Description
RELATED APPLICATIONS
[0001] This application claims the benefit, under 35 U.S.C.
.sctn.119, of U.S. Provisional Patent Application Ser. No.
61/893,021 filed on Oct. 18, 2013, and entitled "Decorative
Fragrance Dispensing System," which is hereby incorporated by
reference in its entirety.
FIELD OF THE DISCLOSURE
[0002] This disclosure generally relates to a decorative fragrance
dispensing system.
BACKGROUND
[0003] Fragrance dispensing products may be used to dispense
fragrance into surrounding air (for example, within a room, office,
workplace, or household), thereby "freshening" the air and creating
a pleasant atmosphere. In creating the pleasant atmosphere, ambient
lighting may also be included as part of a fragrance dispensing
product. Examples of types of fragrance dispensing products may
include candles, air fresheners, electric fragrance dispensers,
etc.
[0004] Some fragrance dispensing products use fragrance elements
such as melted wax, gels, and/or liquids, to hold and dispense
fragrance. These products may become messy if the wax, gels, or
liquids are spilled. Further, children and/or animals may be
inclined to play with or eat the wax, gels, or liquids. Hence,
current fragrance dispensing systems may present a danger to
children and/or animals.
[0005] Some products may use molded EVA plastic infused with
fragrance instead of wax, gels, or liquids. However, such products
use heating elements to heat the EVA plastic to temperatures
between about 100.degree. F. and 150.degree. F. The heat causes the
EVA plastic to release the fragrance. Using a heating element
within a fragrance dispensing system may be dangerous to people or
articles that may come in contact with the heating element or a
heated portion of the fragrance dispensing system. Further, using
molded plastics may not enable sufficient airflow to pass through
the fragrance dispensing system to infuse the air with the
fragrance.
SUMMARY
[0006] Disclosed is a fragrance packet that may be filled with
ethylene vinyl acetate (EVA) beads that are infused with
fragrances. The disclosed fragrance packet may resolve or mitigate
at least one disadvantage of current systems described above and or
one or more additional disadvantages known in the relevant art. The
fragrance packet may have a high fragrance load (e.g., 17%).
Throughout the process of infusing the fragrance into the EVA beads
and during use of the fragrance packet, no additional heat (e.g.,
above room temperature) may be applied to the EVA beads, which may
enable the EVA beads to last longer and to maintain a high level of
fragrance for distribution in multiple applications and settings.
The fragrance packet may be used passively (e.g., as a standalone
apparatus) or actively (e.g., with a fragrance dispensing system
that includes a fan). Hence, the fragrance packet may be
portable.
[0007] In an embodiment, a bead packet apparatus includes a
plurality of beads that have been infused with fragrance. The
apparatus further includes a fabric casing enclosing the plurality
of beads.
[0008] In an embodiment, the plurality of beads include ethylene
vinyl acetate (EVA) beads. The plurality of beads may be configured
to release the fragrance over a period of time in the absence of
heat above room temperature. The fragrance may be released in
response to receiving an air flow between the plurality of beads.
The fabric casing may include a mesh that enables the airflow
through the plurality of EVA beads. A total surface area of the
plurality of EVA beads may be large enough to release a human
detectable amount of fragrance in the absence of heat above room
temperature. A fragrance load of the EVA beads may be at least
17%.
[0009] In an embodiment, the apparatus further includes a hook
configured to attach to the fabric casing. Alternatively, a size
and shape of the bead packet may fit a platform of a fragrance
dispensing apparatus. The fragrance dispensing apparatus may be
configured to receive the bead packet at the platform. The
fragrance dispensing apparatus may further be configured to actuate
air flow through the bead packet, the bead packet remaining
substantially unheated by a scent dispensing apparatus during
actuation of the airflow.
[0010] In an embodiment, a method includes receiving an air flow
between a plurality of beads enclosed by a fabric casing. The
method further includes releasing a fragrance from the plurality of
beads in response to the air flow in the absence of heat above room
temperature.
[0011] In an embodiment, the plurality of beads include ethylene
vinyl acetate (EVA) beads. Releasing the fragrance may occur over a
period of time. Releasing the fragrance may include releasing a
human detectable amount of fragrance in the absence of heat above
room temperature. In an embodiment, the air flow is generated by a
fan of a fragrance dispensing apparatus.
[0012] In an embodiment, a method of forming a bead packet
apparatus includes tumbling a plurality of beads with one or more
fragrance agents. The method further includes encasing a portion of
the plurality of beads into a fabric casing.
[0013] In an embodiment, tumbling the plurality of beads is
performed in a sealed tumbling machine. Tumbling the plurality of
beads may be performed without heating the plurality of beads above
room temperature. Further, tumbling the plurality of beads may be
performed for at least one hour. Alternatively, tumbling the
plurality of beads may be performed for at least three days.
Tumbling the plurality of beads may be performed until a fragrance
load of the beads is at least 17%.

DETAILED DESCRIPTION
[0034] Referring to FIG. 1, an embodiment of a fragrance dispensing
system is depicted and generally designated 100. The fragrance
dispensing system 100 may include a housing 110, an ethylene vinyl
acetate (EVA) bead packet 120, a lower module 130, and a fan 140.
In some embodiments, the fragrance dispensing system 100 may also
include a topper 170.
[0035] The housing 110 may include a platform 112 and a sidewall
116 coupled together such that the platform 112 and the sidewall
116 define a cavity that includes an upper portion 151 and a lower
portion 152. Further, the platform 112 may include one or more
openings, such as the opening 114 defined therein. The opening 114
may communicatively couple a space 150 above the platform 110 to
the upper portion 151 of the cavity. For example, a change of air
pressure within the upper portion of the cavity 151 may cause an
airflow path to pass between the space 150 and the upper portion
151 of the cavity via the openings including the opening 114.
Likewise, the sidewall 116 may include one or more openings, such
as the opening 118 defined therein. The opening 118 may
communicatively couple a space 153 adjacent to the sidewall 116 to
the upper portion 151 of the cavity. The housing 110 may be formed
from and include materials such as ceramic materials, poly resin
materials, wax materials, etc. For example, the housing 110 may
include ceramic, glass, poly resin, plastic, wood, metal,
composites, another type of shapeable material, or a combination
thereof.
[0036] The platform 112 may be configured to receive the EVA bead
packet 120. For example, a size and/or a shape of the platform 112
may retain the EVA bead packet 120 when placed in contact with the
EVA bead packet 120.
[0037] The EVA bead packet 120 may include a plurality of EVA beads
such as the EVA bead 122 and a casing 124 enclosing the plurality
of EVA beads. An embodiment of the EVA bead packet 120 is described
further with reference to FIG. 12.
[0038] The lower module 130 may include a battery 131, a locking
mechanism 132, a recharging cable 133, at least one light emitting
diode (LED) 134, a switch connector 135, a turnable knob 136, a
translucent plastic plate 137, and a controller circuit 138.
Although not depicted in FIG. 1, the lower module 130 may include
additional wires and circuitry coupling the elements of the lower
module 130 together to enable various operations of the lower
module 130 as described herein. The lower module 130 may be coupled
to a fan 140 by a motor 160 to enable the motor and fan as
described herein.
[0039] The battery 131 may include any battery capable of powering
the motor 160 and the at least one LED 134. For example, the
battery 131 may be a rechargeable high capacity lithium ion
battery, such as a low voltage and power consumption DC 3.7 volt
rechargeable lithium ion battery. The battery 131 may be
electrically coupled to the motor 160 and the at least one LED 134
via the controller circuit 138 as described further with reference
to FIG. 2. In an embodiment, the battery 131 may be capable of
operating the fragrance dispensing system 100 as described herein
for a period of at least 80 hours. In one or more other
embodiments, the battery 131 may be a lower capacity battery and
may be capable of operating the fragrance dispensing system 100 as
described herein for a period of less than 80 hours.
[0040] The locking mechanism 132 may include any type of locking
mechanism capable of coupling the housing 110 to the lower module
130 when enabled and releasing the housing 110 from the lower
module 130 when disabled. In an embodiment, the locking mechanism
132 includes a twist locking mechanism. For example, the locking
mechanism 132 may include a notch attached to a side of the lower
module 130 as depicted in FIG. 1. The notch may be received by the
housing 110. A particular embodiment of the locking mechanism is
described further with reference to FIGS. 6A-7.
[0041] The recharging cable 133 may include any type of recharging
cable capable of charging the battery 131. In an embodiment, the
recharging cable 133 is electrically coupled to the battery 131 via
the controller circuit 138 as described with reference to FIG. 2.
The recharging cable 133 may further be configured to couple to an
electrical outlet (e.g., a wall outlet) to receive power for
recharging the battery 131. In an embodiment, the recharging cable
133 is a 1 amp 5 volt rechargeable cable.
[0042] The at least one LED 134 may be configured to produce light
within the upper portion 151 and the lower portion 152 of the
cavity. The light may pass through the translucent plate 137. The
light may further pass through the opening 114, the opening 118, or
both, thereby producing ambient lighting around the fragrance
dispensing system 100. In an embodiment, the at least one LED 134
includes six LEDs coupled to the controller circuit 138.
[0043] The switch connector 135 may be configured to receive the
turnable knob 136 and to place the turnable knob in communication
with a switch of the controller circuit 138. For example, the
switch connector 135 may be keyed with a star shape that enables an
inside of the turnable knob 136 to be press fit to the switch
connector 135 and locked into place. The turnable knob 136 may then
be rotated to activate different settings of the switch connector
135 and an associated switch coupled to the controller circuit
138.
[0044] The translucent plastic plate 137 may cover the at least one
LED 134 thereby separating the at least one LED 134 from the lower
portion 152 of the cavity. In an embodiment, the translucent
plastic plate 137 is cloudy white to modify light from the at least
one LED 134 to generate an ambient lighting. Other types of plates
are also possible, such as a transparent plate.
[0045] The controller circuit 138 may include one or more inputs,
switches, processors, and/or circuits capable of initiating
operations associated with the fragrance dispensing system 100. An
embodiment of the controller circuit 138 is further described with
reference to FIG. 2.
[0046] The fan 140 may include any type of ventilator system
capable of generating an airflow path from the space 150 above the
platform to the lower portion 152 of the cavity via the opening 114
of the platform 112 and via the upper portion 151 of the cavity.
The airflow path may further pass from the lower portion 152 of the
cavity to the space 153 adjacent to the sidewall 116 via the upper
portion 151 of the cavity and via the opening 118 of the sidewall
116. To generate the airflow, the fan 140 may use a reverse motion.
For example, the fan 140 may be configured to pull air down through
the cavity (e.g., from the upper portion 151 to the lower portion
152). In an embodiment, the fan 140 includes two diametrically
opposed blades 142, 144. An angle and size of the blades 142, 143
may reduce a noise emitted by the fan while increasing an airflow
through the airflow path. In an embodiment, the fan includes three
blades. The fan 140 may also be transparent. For example, the fan
140 may be formed of colorless see-through plastic such that light
from the LED 134 may pass through the fan 140.
[0047] The motor 160 may include any type of motor capable of
driving the fan 140. The motor 160 may further include cloth
brushing 162. The cloth brushing 162 may reduce an amount of noise
and/or vibration associated with operation of the motor 160.
[0048] The topper 170 may be configured to fit with the housing
110. When coupled together, the topper 170 and the platform 112 may
define an upper cavity configured to retain the EVA bead packet.
The topper 170 may include at least one opening 172 defined
therein. The at least one opening 172 may enable an air flow path
to pass through the EVA bead packet 120 and the at least one
opening 114 without being restricted.
[0049] During operation, the controller circuit 138 may receive one
or more signals indicating an operating state of the fragrance
dispensing system 100. Particular embodiments of the operating
states of the fragrance dispensing system 100 are described further
with reference to FIG. 2. Based on the operating state, the
controller circuit 138 may provide electrical power to the motor
160 from the battery 131. The motor 160 may convert the electrical
power to mechanical power to drive the fan 140. The fan 140 may
cause air to flow in a particular airflow path. For example, the
fan 140 may draw airflow in a direction away from the EVA bead
packet 120, thereby drawing air from the space 150 above the
platform 110 through the EVA bead packet 120 and through the at
least one opening 112 into the upper portion 151 of the cavity. An
embodiment of the airflow path is further described with reference
to FIG. 3. Depending on the operating state, the controller circuit
138 may further provide electrical power to the at least one LED
134.
[0050] As further operations, a user may be able to disable the
locking mechanism 132 enabling the housing 110 to be separated from
the lower module 130. The housing may be replaced by a second
housing. For example, the user may prefer a style of the second
housing as compared to the housing 110. The second housing may
include a second platform configured to receive the EVA bead packet
120. In an embodiment, a plurality of interchangeable housings with
different designs may be used with lower module 130.
[0051] A benefit associated with the fragrance dispensing system
100 is that the combination of the extended surface area of the EVA
beads with the airflow path produced by the fan 140 may enable the
fragrance dispensing apparatus to dispense fragrance without
heating the EVA beads 122 in contrast to systems that use molded
EVA plastic and/or traditional airflow paths. Other advantages and
benefits of the fragrance dispensing system 100 will be apparent to
persons of ordinary skill in the relevant art having the benefit of
this disclosure.
[0052] Referring to FIG. 2, a block diagram of an embodiment of a
system for fragrance dispensing is depicted and generally
designated 200. The system 200 may include a controller circuit
210, a four wire switch 220, a power save switch 222, a battery
charge input 224, a fan motor 230, at least one LED 232, and a
battery 240. The controller circuit 210 may correspond to the
controller circuit 138 of FIG. 1, the four wire switch 220 may
correspond to and be coupled to the switch connector 135, and the
battery charge input 224 may be configured to couple to the
recharging cable 133. Further, the fan motor 230 may correspond to
the motor 160 and the at least one LED 232 may correspond to the at
least one LED 134.
[0053] The controller circuit 210 may include one or more
integrated circuits 212, a DC battery controller 214, a recharge
controller 216, and a motor controller 218. Although, the
integrated circuits 212, the DC battery controller 214, the
recharge controller 216, and the motor controller 218 are depicted
as distinct, in other embodiments, one or more of the integrated
circuits 212, the DC battery controller 214, the recharge
controller 216, and the motor controller 218, or portions thereof,
may be combined.
[0054] In an embodiment, the controller circuit 210 includes a
printed circuit board (PCB). The PCB may be coupled to the four
wire switch 220, the power save switch 222, and the battery charge
input 224. The PCB may be further coupled to the integrated
circuits 212, the DC battery controller 214, the recharge
controller 216, and the motor controller 218. The PCB may also be
coupled to the fan 230 and the at least one LED 232.
[0055] The integrated circuits 212 may include a processor capable
of performing operations associated with the system 200 as
described herein. For example, the processor may include any type
of processing device such as a central processing unit (CPU), a
digital signal processor (DSP), a peripheral interface controller
(PIC), and/or another type of processing element.
[0056] The DC battery controller 214 may perform operations to
selectively operate the battery 240. For example, the DC battery
controller 214 may disconnect an output of the battery 240 in
response to a determination that the battery has reached a
predetermined level of discharge. Further, the DC battery
controller 214 may reduce an amount of current drawn from the
battery 240 in response to determining that the amount of current
exceeds a predetermined threshold. Additionally, the DC battery
controller may disconnect an output of the battery 240 in response
to an input received from the four wire switch, 220, the power save
switch 222, the battery charge input 224, or a combination
thereof.
[0057] The recharge controller 216 may receive a charging current
from the battery charge input 224. Based on the charging current,
the recharge controller 216 may generate a charging input usable to
charge the battery 240. The charging input may be directed by the
recharge controller 216 into the battery 240. Upon detecting that
the battery 240 is charged beyond a threshold, the recharge
controller 216 may disconnect the charging input from the battery
240.
[0058] The motor controller 218 may selectively control the fan
motor 230 to adjust a speed of the fan motor 230. For example, the
motor controller 218 may receive a signal from the integrated
circuits 212 indicating that a speed of the fan motor 230 should be
increased or decreased. Based on the signal, the motor controller
218 may increase an amount of power supplied to the fan motor
230.
[0059] During operation, the controller circuit 210 may selectively
enter an off state, a light state, a low state, or a high state.
For example, a user may position the four wire switch 220 to one of
four positions corresponding to a particular state. The particular
state may be communicated to the integrated circuits 212. The
controller circuit 210 may refrain from operating both the fan
motor 230 and the one or more LEDs 232 while in the off state. The
controller circuit 210 may further refrain from operating the fan
motor 230 and may operate the one or more LEDs 232 while in the
light only state. The controller circuit 210 may also operate the
fan motor 230 at a low speed while in the low state. The controller
circuit 210 may operate the fan motor 230 at a high speed while in
the high state. Both the high state and the low state may
correspond to and be included as part of an on state of the system
200.
[0060] The system 200 may further selectively enter a power saving
state. For example, a user may position the power save switch 222
to one of two positions indicating to the integrated circuits 212
whether the system 200 is to enter the power saving state. While in
the power saving state, the controller circuit 210 may perform
power saving operations for a first period of time and may be
powered off for a second period of time. To illustrate, the
controller circuit 210 may perform power saving operations during 4
hours of a 24 hour period. The power saving operations may include
operating the fan for a first duration (e.g., for a 15 minute
period) and ceasing to operate the fan for a second duration (e.g.,
for a 5 minute period). Thus, during the power saving state, the
system 200 may conserve power, thereby prolonging an amount of time
between battery charges.
[0061] A benefit associated with the system 200 including the power
save switch 222 is that the system 200 may be more portable as
compared to fragrance dispensing systems that do not have power
save options. For example, the system 200 may be operated
independent of a power input for longer than other systems. In an
embodiment, the battery 240 may be able to operate the system 200
for more than 80 hours without being recharged. Other advantages
and benefits of the system 200 will be apparent to persons of
ordinary skill in the relevant art having the benefit of this
disclosure.
[0062] Referring to FIG. 3, a diagram of an embodiment of an air
flow path of an embodiment of the system 100 for fragrance
dispensing is depicted. In following the air flow path, air may
move from the space 150 above the platform 112 to the upper portion
151 of the cavity via the at least one platform opening 114. In
passing through the platform 112, the air flow may further pass
through the EVA bead packet 120. In passing through the EVA bead
packet 120, the air flow may absorb fragrance from the EVA bead
packet 120. The scented air may then flow from the upper portion
151 of the cavity to the lower portion 152 of the cavity due to
suction created by the fan 140. The scented air may be compressed
in the lower portion 152 of the cavity such that the scented air is
forced upward along the sidewall 116 of the housing 110. Hence, the
air flow path may pass upward from the lower portion 152 of the
cavity to the upper portion 151 of the cavity. From there, the air
flow path may pass from the upper portion 151 of the cavity to the
space 153 adjacent to the sidewall 116 via the at least one
sidewall opening 118. Hence, the system 100 may pull air downward
through the EVA bead packet 120 and subsequently force the air
outward from the housing 110. Although, FIG. 3 is described in
terms of having at least one platform opening 114 and at least one
sidewall opening 118, the at least one platform opening 114 may
include multiple openings to increase an air flow into the housing
110 and the at least one sidewall opening 118 may include multiple
openings to increase an air flow out of the housing 110.
[0063] A benefit of the air flow pattern described with reference
to FIG. 3 is that an amount of air passing through the EVA bead
packet 120 and subsequently passing though the at least one
sidewall opening 118 may be greater as compared to systems that do
not pull air downward into the lower portion 152 of the cavity. For
example, alternate systems may experience less air being directed
through the EVA bead packet 120 due to a lack of control over the
air flow path. Hence, the system 100 may better disperse fragrance
from the EVA bead packet 120 as compared to systems that do not
pull air downward and subsequently force the air outward. Other
advantages and benefits of the air flow path of the system 100 will
be apparent to persons of ordinary skill in the relevant art having
the benefit of this disclosure.
[0064] Referring to FIGS. 4A-4C, an embodiment of the fragrance
dispensing system 100 is depicted from multiple views. Although
FIGS. 4A-4C depict the fragrance dispensing system 100 as including
a weaved pattern defining the at least one platform opening 114 and
the at least one sidewall opening 118, other embodiments of the
fragrance dispensing system 100 may include other designs.
[0065] Referring to FIG. 4A, an embodiment of the fragrance
dispensing system 100 including the topper 170 is depicted from a
top angled view. The topper 170 may include at least one opening
172 defined therein. In an embodiment, the topper 170 includes a
plurality of openings defined therein. The collective area of the
openings may be greater than or equal to the collective area of
platform openings (e.g. the platform opening 114) defined in the
platform 112. By having an area that is greater than or equal to
the area of the platform openings, the topper 170 may refrain from
causing additional air flow resistance to the platform 112. Hence,
air may flow freely through the topper 170.
[0066] The topper 170 may be coupled to the housing 110 via a press
fit mechanism. In other embodiments, other mechanisms may be used
to secure the topper 170 to the housing 110. When coupled to the
housing 110, the topper 170 and the platform 112 may define a
cavity that is configured to retain the EVA bead packet 120.
[0067] A benefit of the topper 170 is that the EVA bead packet 120
may be retained securely in place, thereby preventing the EVA bead
packet from falling or becoming lost should the fragrance
dispensing system be moved or jostled. Other benefits and
advantages of the topper 170 will be apparent to persons of
ordinary skill in the relevant art having the benefit of this
disclosure.
[0068] Referring to FIG. 4B, an embodiment of the fragrance
dispensing system 100 with the topper 172 removed is depicted from
a top angled view. The platform 112 may be concave shaped to better
retain the EVA bead packet 120. As depicted in FIG. 4B a plurality
of platform openings (e.g., including the platform opening 114) may
be defined in the platform 112. Having multiple platform openings
may enable the system 100 to have better air flow through the
platform 112, and thereby through the EVA bead packet 120, as
compared to systems that have relatively few openings. Other
benefits and advantages of the platform 112 with platform openings
defined therein will be apparent to persons of ordinary skill in
the art having the benefit of this disclosure.
[0069] Referring to FIG. 4C, an embodiment of the fragrance
dispensing system 100 that includes the EVA bead packet 120 is
depicted from a side view. The EVA bead packet 120 may be sized to
fit over the platform openings 114. When the system 100 is
activated (e.g., by the turnable knob 136), fragrance may be drawn
from the EVA bead packet 120 downward into the housing 110. The
fragrance may then be pushed out through a plurality of sidewall
openings (e.g., including the sidewall opening 118) in order to
disperse the fragrance through a room. A cumulative area of the
sidewall openings may be greater than or equal to a cumulative area
of the platform openings, thereby preventing restriction of air
flow through the fragrance dispersing system 100. Other benefits
and advantages of the sidewall 116 with sidewall openings defined
therein will be apparent to persons of ordinary skill in the art
having the benefit of this disclosure.
[0070] Referring to FIG. 5, an exploded view of an embodiment of a
lower module is depicted and generally designated 530. The lower
module 530 may correspond to the lower module 130. For example, the
lower module 530 may include the battery 131, the locking mechanism
132, the at least one LED 134, the translucent plastic plate 137,
the controller circuit 138, the fan 140, and the motor 160. The
lower module 530 may also include an o ring 590, a motor mount 539,
and a motor cover 564.
[0071] The o ring 590 may help secure a housing (e.g., the housing
110) coupled to the lower module 530. The o ring 590 may further
seal the housing (e.g., the housing 110) to the lower module 530,
thereby protecting the air flow pattern described with reference to
FIG. 3 by preventing air seepage. In an embodiment, the o ring may
be a 3 mm thick rubber gasket. The motor mount 539 may be
configured to receive and retain the motor 160. The motor mount 539
may further be shaped to substantially retain the battery 131 as
well, thereby reducing vibration and noise associated with the
lower module 530. The motor cover 564 may include a plastic white
motor cover. A non-transparent finish may help modify lighting
received by the at least one LED 134 to create ambient lighting. In
an embodiment, the motor cover 564 is coupled to the motor mount
539 by screws on either side of the motor cover 564. Other benefits
and advantages of the o ring 590, the motor mount 539, and the
motor cover 564 will be apparent to persons of ordinary skill in
the relevant art having the benefit of this disclosure.

The lower module 630 may correspond to the lower module 130. The
lower module 630 may include a switch 608. The switch 608 may
correspond to the power save switch 222 of FIG. 2. The lower module
630 may also include screw holes 604, 606. The screw holes 604 may
enable the lower module 630 to couple to the translucent plate 137
and the screw holes 606 may enable the lower module 630 to couple
to the motor mount 539.
[0073] The lower module 630 may further include molded letters 602.
The molded letters 602 may provide instructions to a user for
activating the locking mechanism 132. For example, the locking
mechanism 132 may be a twisting locking mechanism, and the molded
letters 602 may instruct the user to rotate the lower module 630 to
lock the lower module 630 to a housing such as the housing 610.
[0074] Referring to FIG. 6B, an embodiment of a housing 610 usable
with the first embodiment of the locking mechanism is depicted. The
housing 610 may include at least one half-moon opening 612 defined
therein. The at least one half-moon opening may enable the lower
module 630 to be inserted into the housing 610 and twisted into
place. For example, the lower module 630 may include a notch that
fits into the half-moon opening 612. In an embodiment, the
half-moon opening 612 fits the switch connector 135 such that the
switch connector 135 may be positioned to receive the switch 136
through an opening in the housing 610. The housing 610 may further
include additional half-moon openings as depicted in FIG. 6B. In an
embodiment, the housing 610 includes three half-moon openings.
[0075] A benefit of the twist locking mechanism of FIGS. 6A and 6B
is that a user may easily lock and unlock the lower module 630 from
the housing 610, thereby enabling the user to easily replace the
housing 610 with a second housing of a preferred style. Other
benefits and advantages of the twist locking mechanism of FIGS. 6A
and 6B will be apparent to persons of ordinary skill in the art
having the benefit of this disclosure.
[0076] Referring to FIG. 7, an embodiment of a lower module 730
including a second embodiment of a locking mechanism is depicted.
The second locking mechanism may include at least one hole 702
defined within the lower module 730. The at least one hole 702 may
be configured to receive a screw therethrough to lock the lower
module 730 to a housing (e.g., the housing 110). The second locking
mechanism may more securely lock the lower module 730 to a housing
as compared to locking mechanisms that do not use screws.
[0077] Referring to FIG. 8, an embodiment of a lower module 830
that includes a switch mating connector 802 is depicted. The lower
module 830 may correspond to the lower module 130. The switch
mating connector 802 may correspond to the switch connector 135 and
may be keyed with a star shape to enable an inside of a turnable
knob to fit tightly to the switch mating connector 802 and to
enable the turnable knob to turn a switch (e.g., the four wire
switch 220 of FIG. 2) to different settings as described with
reference to FIG. 9. Further, the turnable knob may be removed to
enable a housing to be removed from the lower module 830.
[0078] Referring to FIG. 9, an embodiment of the lower module 830
is depicted with a turnable knob 804 fit onto the switch mating
connector 802. By turning the turnable knob 804, a switch may be
turned to different settings as described herein.
[0079] Referring to FIGS. 10A and 10B, an embodiment of the
turnable knob 804 is depicted. FIG. 10A depicts a lower view of the
embodiment of the turnable knob 804. An inside 806 of the turnable
knob may match the star key of the switch mating connector 802.
FIG. 10B depicts an upper view of the embodiment of the turnable
knob 804.
[0080] Referring to FIG. 11, an embodiment of a method of fragrance
dispensing is depicted and generally designated 1100. The method
1100 may include receiving an EVA bead packet at a platform of a
fragrance dispensing apparatus, at 1102. For example, the EVA bead
packet 120 may be received at the platform 112.
[0081] The method 1100 may further include actuating airflow
through the EVA bead packet, at 1104. The EVA bead packet may
remain substantially unheated by a fragrance dispensing apparatus
during actuation of the airflow. For example, the fan 140 may
actuate air flow through the EVA bead packet 120, thereby infusing
the air with a fragrance received from the EVA bead packet 120
without heating the EVA bead packet 120.
[0082] The method 1100 may also include generate an airflow path
from a space above a platform to a lower portion of a cavity via
the EVA bead packet and via at least one platform opening defined
within the platform, from the lower portion of the cavity to an
upper portion of the cavity, and from the upper portion of the
cavity to a space adjacent to a sidewall via at least one sidewall
opening, at 1106. For example, the air flow path described with
reference to FIG. 3 may be employed to fill a space with
fragrance.
[0083] A benefit of the method 1100 is that fragrance may be
infused into air passing through the EVA bead packet and may be
directed efficiently to a space without heating the EVA bead packet
or employing any type of heating element. Other benefits and
advantages of the method 1100 will be apparent to persons of
ordinary skill in the art having the benefit of this
disclosure.
[0084] Referring to FIG. 12, an embodiment of a bead packet
apparatus is depicted and generally designated 1200. The bead
packet 1200 may include a plurality of beads 1202 and a fabric
casing 1204. In an embodiment, the bead packet 1200 may have a size
and shape that enables the bead packet to fit a platform of a
fragrance dispensing apparatus. For example, the bead packet 1200
may correspond to the EVA bead packet 120 and may be usable with
the fragrance dispensing apparatus 100.
[0085] The plurality of beads 1202 may include EVA beads infused
with fragrance. Further, the plurality of beads 1202 may be
configured to release the fragrance over a period of time. The
fragrance may be released in response to receiving an air flow
between the plurality of beads 1202. The amount of fragrance
released in response to the air flow may depend on a total surface
area of the plurality of beads 1202 that come in contact with the
air flow. A total surface area of the plurality of beads 1202 may
be sufficiently large to enable a human detectable amount of
fragrance to be released. As used herein, a human detectable amount
of fragrance is a concentration of scent that enables a typical
human to smell the fragrance when located proximate to the bead
packet 1200. Different fragrance agents may have different
detectability thresholds. Detectability thresholds corresponding to
particular fragrance agents are known to persons of ordinary skill
in the art. Due to the large surface area that the plurality of
beads 1202 present, the human detectable amount of fragrance may be
released in the absence of heat above room temperature. As used
herein, room temperature means a range of temperatures between
60.degree. F. 100.degree. F. In an embodiment, the plurality of
beads 1202 may release a human detectable amount of fragrance at
below 75.degree. F. In an embodiment, the beads are infused with a
fragrance load of 17 percent. The fragrance load may be an
indication of percentage of fragrance agent volume as compared to a
volume of fragrance element (e.g., the plurality of fragrance beads
1202).
[0086] Particular fragrances that may be infused in the plurality
of beads 1102 may include Accord, Amber, Amber Crystals, Aniseed,
Apple, Baked Cookie, Bartlett Pear, Basil Leaf, Bergamot,

other types of fragrances, or a combination thereof. The particular
fragrances listed herein are intended as a non-limiting example. It
should be understood that in one or more other embodiments the
plurality of beads 1102 may be infused with other types of
fragrances not listed herein.
[0087] The fabric casing 1204 may include a mesh that enables air
flow through the plurality of beads. In an embodiment, the fabric
casing 1104 may also include a hook receiver 1206. The hook
receiver 1206 may include string or twine coupled to the fabric
casing 1104. The hook receiver may be configured to receive a hook
1108, thereby coupling the fabric casing 1104 to the hook 1108.
[0088] A benefit of the fragrance packet 1200 may be that the
plurality of beads 1202 may release a fragrance without being
heated. Further, because the fragrance packet 1200 may be
relatively small it may be portable for use in a variety of
applications. Also, the hook 1208 may enable the fragrance packet
1200 to be attached to household items, such as a laundry basket, a
car mirror, various knobs, etc. Additional advantages and benefits
of the fragrance packet 1200 will be apparent to persons of
ordinary skill in the relevant art having the benefit of this
disclosure.
[0089] Referring to FIG. 13, an embodiment of a tumbler machine is
depicted and generally designated 1300. The tumbler machine 1300
may be used to tumble a plurality of beads 1302 with one or more
fragrance agents. The plurality of beads 1302 may correspond to the
plurality of beads 1202.
[0090] The tumbler machine 1300 may include a mixing mechanism
1304. For example, the mixing mechanism may include an auger,
mixing arm, another mixing element, or any combination thereof. The
tumbler machine 1300 may further include a lid 1306. The lid 1306
may be configured to seal the tumbler machine 1300 to prevent
fragrance agents from seeping out of the tumbler machine 1300
during tumbling.
[0091] Referring to FIG. 14, an embodiment of a method of
dispersing fragrance is depicted and generally designated 1400. The
method 1400 may include, receiving an air flow between a plurality
of beads enclosed by a fabric casing, at 1402. For example, the
plurality of beads 1202 may receive an air flow between the
plurality of beads 1202. In an embodiment, the plurality of beads
1202 may include EVA beads.
[0092] The method 1400 may also include releasing a fragrance from
the plurality of beads in response to the air flow in the absence
of heat above room temperature, at 1404. For example, the plurality
of beads 1202 may release a fragrance in response to the air flow.
As explained herein, the fragrance may be released over a period of
time. Further, the fragrance may be released in the absence of
additional stimuli such as heat. In an embodiment, the air flow may
be generated by a fan, as described with reference to FIGS. 1 and
3.
[0093] A benefit associated with the method 1400 may be that the
plurality of beads may release fragrance without resorting to using
a heating element, thereby making the bead packet safer as compared
to fragrance dispensing products that use heating elements.
Additional advantages and benefits of the method 1400 will be
apparent to persons of ordinary skill in the relevant art having
the benefit of this disclosure.
[0094] Referring to FIG. 15, an embodiment of a method of
manufacturing a bead packet is depicted and generally designated
1500. The method 1500 may include tumbling a plurality of beads
with one or more fragrance agents in a sealed tumbler machine
without heating the plurality of beads above room temperature, at
1502. For example, the plurality of beads 1302 may be infused with
fragrance by tumbling the plurality of beads 1302 in the tumbler
machine 1300 with one or more fragrance agents. The tumbler machine
1300 may be sealed by the lid 1306 to prevent the one or more
fragrance agents from seeping out of the tumbler machine 1300,
thereby strengthening the extent to which the plurality of beads
1302 become infused with a fragrance. The tumbling may be performed
for at least an hour for some fragrance agents. Other fragrance
agents may require at least three days for the beads to become
infused with the fragrance. In an embodiment, the tumbling is
performed until the fragrance load of the plurality of beads 1302
is at least 17 percent.
[0095] The method 1500 may further include encasing a portion of
the plurality of beads into a fabric casing, at 1504. For example,
the plurality of beads 1302, or at least a portion thereof, may be
encased within a fabric casing (e.g., the fabric casing 1204).
[0096] A benefit of the method 1500 is that the beads may be
infused with fragrance without being heated as compared to
manufacturing methods that do not use a sealed tumbler or that do
not use beads which inherently have a high surface area. Additional
advantages and benefits of the method 1500 will be apparent to
persons of ordinary skill in the relevant art having the benefit of
this disclosure.
[0097] Although various embodiments have been shown and described,
the present disclosure is not so limited and will be understood to
include all such modifications and variations are would be apparent
to one skilled in the art.
