TECHNICAL FIELD
[0003] This invention relates generally to smoking devices, and
more particularly relates to smoke and odor elimination filters,
devices and methods.
BACKGROUND
[0004] Smoking is a practice in which a combustible substance,
e.g., tobacco, cannabis or herbs, is burned and the resulting smoke
inhaled. Combustion of the substance causes the release of active
drugs such as nicotine or THC and makes them available for
absorption through the lungs. The most common way of smoking today
is through cigarettes, primarily industrially manufactured but also
hand-rolled using rolling paper. Other smoking tools includes
traditional pipes, cigars, hookahs and bongs.
[0005] People smoke for recreation, as a part of rituals, in search
of a spiritual enlightenment, and for medical purposes. The history
of smoking can be dated to as early as 5000 BC, and has been
recorded in many different cultures around the world. Early smoking
evolved in association with religious ceremonies, as offerings to
deities, in cleansing rituals, or as a process of divination. The
practice of smoking has become commonplace.
[0006] It will be appreciated that, while cannabis for recreational
use is illegal in many parts of the world, its use as a medicine is
legal in a number of territories, including Canada, Austria,
Germany, the Netherlands, Spain, Israel, Italy, Finland, and
Portugal. In the United States, permission for medical cannabis
varies from state to state, several having enacted laws to allow
regulated cannabis consumption, possession, cultivation, and
distribution for medicinal use.
[0007] When non-smokers are exposed to secondhand smoke, it is
commonly referred to as passive smoking. Non-smokers who breathe in
secondhand smoke take in the nicotine, THC and/or other chemicals
just like smokers do. Passive smoking has played a central role in
the debate over the harms and regulation of tobacco products. Since
the early 1970s, the tobacco industry has been concerned about
passive smoking as a serious threat to its business interests.
Passive smoking was perceived as motivation for stricter regulation
of tobacco products as well as for smoking bans in workplaces and
indoor public establishments, such as restaurants, bars and night
clubs.
[0008] Smoking releases odors that get into hair, clothing, and
other surfaces, even after the smoke is no longer visible. Some
researchers call this remnant odor "thirdhand" smoke. Essentially,
the particles caused by smoking settle on surfaces and can be
measured long after a person has finished smoking.
[0009] What is desired is a mechanism for reducing or eliminating
secondhand and thirdhand smoke.

provides a pipe, comprising a combustion bowl with bowl vents; an
inhalation path for drawing smoke from the combustion bowl through
the bowl vents during inhalation; an exhalation filter; and an
exhalation path for forcing exhaled smoke through the exhalation
filter during exhalation.
[0011] The pipe may further comprise a mouthpiece on both the
inhalation path and the exhalation path. The inhalation path may
include a one-way inhalation valve between the combustion bowl and
the mouthpiece. The pipe may further comprise a lid over the
combustion bowl, the lid creating a substantially airtight
inhalation seal with the combustion bowl. The lid may include a
one-way inhalation valve. The pipe may further comprise exhalation
vents, wherein the exhalation path includes a one-way exhalation
valve between the mouthpiece and the exhalation vents. The one-way
exhalation valve may be part of the exhalation filter. The

DETAILED DESCRIPTION
[0035] The following description is provided to enable any person
skilled in the art to make and use the invention. Various
modifications to the embodiments are possible, and the generic
principles defined herein may be applied to these and other
embodiments and applications without departing from the spirit and
scope of the invention. Thus, the invention is not intended to be
limited to the embodiments and applications shown, but is to be
accorded the widest scope consistent with the principles, features
and teachings disclosed herein.
[0036] FIGS. 1a-1e illustrate a smoke and odor elimination pipe
100, in accordance with an embodiment of the present invention.
FIG. 1a is a perspective view of the pipe 100. FIG. 1b is a side
view of the pipe 100. FIG. 1c is a top view of the pipe 100. FIG.
1d is a bottom view of the pipe 100. FIG. 1e is a front view of the
pipe 100.
[0037] As shown in FIGS. 1a-1e, the pipe 100 has six sides, namely,
a top side 151, a bottom side 152, a front side 153, a rear side
154, a left side 155, and a right side 156. The pipe 100 includes a
mouthpiece 105 and one-way exhalation vents 115 on the front side
153, and a flip-top lid 110 with one-way inhalation vents 120 on
the top side 151.
[0038] In use, the smoker opens the lid 110, exposing a combustion
bowl (not shown) with combustible substance therein. The smoker
applies a flame over the combustible substance, e.g., using a
butane lighter, and inhales through the mouthpiece 105. Airflow
causes the combustible substance to burn and smoke to pass through
an inhalation path in the pipe 100 via an inhalation filter (not
shown) and out the mouthpiece 105 to the smoker. The smoker closes
the lid 110, which effectively prevents air from flowing out the
opening exposed when the lid 110 is open. Air can still be drawn
through the one-way inhalation vents 120. The smoker then exhales
through the same mouthpiece 105. The smoke passes through an
exhalation path in the pipe 100 through an exhalation filter (not
shown) and out the exhalation vents 115. The exhalation filter
scrubs the smoke and odor particles.
[0039] In one embodiment, the pipe 100 is about 4 inches long
(front to rear), 1.5 inches tall (top to bottom), and 7/8 inch wide
(left to right). Components of the pipe 100 may be made of a metal
such as aluminum or of plastic.
[0040] FIG. 2 is an exploded view of the pipe 100, in accordance
with an embodiment of the present invention.
[0041] The pipe 100 includes a body 201 with two channels, namely,
a lower channel 210 and an upper channel 211. An end cap 208 with a
through-hole (not shown) is positioned on the rear end of the lower
channel 210. A bowl housing 202, possibly made of aluminum, is
positioned near the rear side of the body 201, behind the end cap
208. Although not shown, bowl vents may be disposed on the
underside of the bowl 212. The shape of the bowl housing 202 allows
air to be drawn through the bowl vents on the underside of the bowl
212 to an intermediate chamber behind the end cap 208 and through
the upper channel 211. Although not shown, in some embodiments, an
inhalation filter may be positioned in the upper channel 211. The
shape of the bowl housing 202 also allows air to pass from the
upper channel to the intermediate chamber under the bowl 212,
through the end cap 208, and through the lower channel 210.
[0042] A fitting 205 is positioned in the front end of the body
201. The fitting 205 includes two passageways, namely, an upper
passageway 213 that interfaces with the upper channel 211 and a
lower passageway 214 that interfaces with the lower channel 210. In
some embodiments, the fitting 205 is attached airtight to the body
210, e.g., using glue. The upper passageway 213 may be configured
to accept the mouthpiece 105 mounted therein, possibly with an
o-ring 204 therebetween to create an airtight seal. The lower
passageway 214 may be configured to accept an exhalation filter
cartridge 203 into the lower channel 210 and an exhalation vent cap
206. In some embodiments, the exhalation vent cap 206 is removable
to allow replacement of the exhalation filter cartridge 203. In
some embodiments, the end cap 206 is part of or integrated with the
exhalation filter cartridge 203.
[0043] The pipe 100 includes an inhalation path and an exhalation
path. As shown and described with reference to the pipe 100, the
inhalation path and exhalation path of pipe 100 overlap. To ensure
that air is not drawn from the exhalation filter cartridge 203
during inhalation and that air is not forced through the combustion
bowl 212 during exhalation, one or more one-way inhalation valves
and one or more one-way exhalation valves may be employed. In some
embodiments, the one-way inhalation valve may be attached to the
flip top lid 110. In some embodiments, the one-way inhalation valve
may be a flap (similar to the flap 303 of FIG. 3) positioned on the
under side of the flip-top lid 110. Therefore, during exhalation,
the inhalation flap prevents air from exiting the flip-top lid 110,
and forces the air through the lower channel. In some embodiments,
a one-way exhalation valve may be disposed in or on the exhalation
filter cartridge 203, in the body 201, on the end cap 208, or in
the exhalation vent cap 206. In some embodiments, the one-way
exhalation valve may be a flap (similar to the flap 303 of FIG. 3)
positioned on the front side of the end cap 208. Thus, during
inhalation, the flap prevents air from being drawn from the lower
channel 210, and allows air to flow through the lower channel.
[0044] FIG. 3 is an exploded view of a flip-top lid assembly 300,
in accordance with some embodiments. The flip-top lid assembly 300
includes the flip-top lid 110 with inhalation vents 120
therethrough, a rear wall 312 extending downward from the backside
of the lid 110, a pivot bore 310 through the rear wall 312 from the
left to the right, and a finger lever 311 that when positioned on
the body 201 extends past the rear side 154 to cause rotation of
the flip-top lid about the pivot bore 310 when pressed upon. A
first dowel 308 is inserted into the pivot bore 310 and lee torsion
springs 307 are attached to the first dowel 308. The first dowel
308 may include a dowel bore 315 therethrough.
[0045] As shown, a one-way inhalation flap 303 may be attached to
the lid 110 to prevent airflow out of the inhalation vents 120. A
lid gasket 302 may be positioned on the underside of the lid 110,
and held in place by a combustion bowl plate 305. The combustion
bowl plate 305 may be secured to the lid 110 using screws 304. It
will be appreciated that the combustion bowl plate 305 may be made
of metal to protect the gasket 302 and the one-way inhalation flap
303 from damage by the burning combustible substance in the bowl
212.
[0046] FIG. 4 is an exploded view of the flip-top lid assembly 300
positioned for connection to the bowl housing 202. As shown, a
second dowel 403 may be positioned through holes 402 in the bowl
housing 202 and through the dowel bore 315 of the first dowel 308.
It will be further appreciated that the lee torsion springs 307 may
be used to bias the flip-top lid 110 in a closed and to press the
lid gasket 302 in an airtight position on the bowl housing 202.
Pressing on the finger lever 311 causes a rotational force to
counter the bias of the springs 307, thus opening the flip-top lid
assembly 300 to expose the bowl 212.
[0047] FIGS. 5a-5f illustrate the internal details of the pipe 100,
in accordance with an embodiment of the present invention.
[0048] FIG. 5a illustrates a front view of the pipe 100, and
identifies plane A-A half way between the left and right sides of
the front face.
[0049] FIG. 5b illustrates a sectional view of the pipe 100 at
plane A-A. When the flip-top lid 110 is open or closed, inhalation
draws air from the mouthpiece 105, which draws air from the upper
channel 211, which draws air from an intermediate path 503, which
draws air from a intermediate chamber 505 under the bowl 212. A
one-way exhalation flap 507 prevents air from being drawn from the
lower channel 210 and the exhalation filter cartridge 203. Instead,
air is drawn through bowl vents 520 on the underside of the bowl
212, which draws smoke from the burning combustible substance in
the bowl 212. This may be referred to as the "inhalation path," in
this embodiment. During exhalation, air is forced into the
mouthpiece 105, which forces air into the upper chamber 211, which
forces air through the intermediate path 503 to the intermediate
chamber 505. The one-way inhalation flap 303 in the flip-top lid
assembly 300 (see FIG. 3) prevents air from being forced through
combustion bowl 202. Instead, the one-way exhalation flap 507 in
the lower channel 210 opens, allowing the air to pass into the
lower channel 210, though the exhalation filter cartridge 203, and
out the exhalation vents 115. In some embodiments, the exhalation
flap 507 (or some other one-way exhalation valve) may be positioned
in this and/or other locations, such as in the exhalation filter
cartridge 203 or near the exhalation vents 115. This may be
referred to as the "exhalation path," in this embodiment.
[0050] FIG. 5c illustrates a sectional view of the rear portion of
the pipe 100 through the bowl 212. As shown, bowl housing 202
includes bowl vents 520 between the bowl 212 and the chamber
505.
[0051] FIG. 5d illustrates a side view of the pipe 100, in
accordance with an embodiment of the present invention. FIG. 5d
defines plane B-B as a section through the upper channel 211 and
defines plane C-C as a section through the lower channel 210.
[0052] FIG. 5e illustrates sectional view of plane B-B of the pipe
100. As shown, the bottom of the bowl 212 includes bowl vents
520.
[0053] FIG. 5f illustrates sectional view at plane C-C of the pipe
100. As shown, in an embodiment, the lower channel 210 may include
ridges that cooperate with ridges on the exhalation filter
cartridge 203.
[0054] FIG. 6 is a sectional view of an example pipe 500, in
accordance with an embodiment of the invention. The pipe 500
includes an upper channel 635, a lower channel 655, and an
intermediate channel 640. An exhalation filter 650 is positioned in
the lower channel 655. A one-way exhalation valve 645 is positioned
in the intermediate channel 640. A one-way inhalation valve 630 is
positioned in the upper channel 635. A mouthpiece is positioned at
the front side of the upper channel 635 of the pipe 500. A flip-top
lid 605 is positioned at the rear side of the upper channel 635 of
the pipe 500. A combustion bowl 615 is positioned under the
flip-top lid 605. An inhalation filter 620 is positioned between
the bowl 615 and the mouthpiece 625 in the upper channel 635.
Exhalation vents 655 are positioned in the front side of the lower
channel 655 of the pipe 500.
[0055] Accordingly, during inhalation, air is drawn from the
mouthpiece 625. The one-way inhalation valve 630 allows air to pass
through the upper channel 635, through the inhalation filter 620,
and from the combustion bowl 615. The exhalation valve 645 prevents
air from being drawn from the lower channel 655. During exhalation,
air is forced into the mouthpiece 625, which forces air through the
intermediate channel 640 via the one-way exhalation valve 645, to
the lower channel 655, through the exhalation filter 650 and out
the exhalation vents 655. The one-way inhalation valve 630 prevents
are being exhaled through the inhalation filter 620 or the
combustion bowl 615.
[0056] FIG. 7 illustrates an exploded view of an exhalation pipe
700, in accordance with an embodiment of the present invention.
[0057] As shown, the exhalation pipe 700 includes an elliptical
body 705 with a filter channel 725 therethrough, threading (not
shown) on the rear internal side of the elliptical body 705, and a
passageway (not shown) on the front side. A mouthpiece 710 is
attached onto the front side of the elliptical body (possibly with
glue). An exhalation filter cartridge 203 is inserted into the
filter channel 725. An end cap 715 includes exhalation vents 720
and threading 730 that cooperates with the threading in the body
705.
[0058] In use, the smoker inhales smoke from a cigarette, pipe,
bong, cigar or other smoking apparatus. The smoker then exhales
through the mouthpiece 710. The smoke travels through the
mouthpiece 710, through the passageway, into the channel 725,
through the exhalation filter cartridge 203, and out the exhalation
vents 720. The filter 203 scrubs the smoke and odor particles.
[0059] In some embodiments, the body 705 may be made of extruded
aluminum, plastic, ferrous metals, precious metals, etc. The
mouthpiece 710 may be machined stainless steel, plastic, ferrous
metals, precious metals, etc. The end cap 715 may be machined
stainless steel, plastic, ferrous metals, precious metals, etc.
[0060] FIGS. 8a-8d illustrate an exhalation pipe 700.
[0061] FIG. 8a illustrates a side view of the exhalation pipe 700.
As shown, the pipe 700 may be about 4 inches in length, e.g., 3.93
inches. FIG. 8a defines plane A-A.
[0062] FIG. 8b illustrates a sectional view of exhalation pipe 700
at plane A-A. As shown, the pipe 700 includes a mouthpiece press
fit to the body 705. The end cap 715 is screwed onto the body 705
via threading 730.
[0063] FIG. 8c illustrates a front view of the pipe exhalation 700.
As shown, in some embodiments, the pipe 700 is about 1.3 inches
across the longitudinal axis of the elliptical body 705 and about
0.95 inches across the latitudinal axis of the elliptical body 705.
The diameter of the circular end cap 715 may be about 1.3 inches,
allowing portions of it to extend beyond the body 705 for easy
rotational manipulation by the user.
[0064] FIG. 8d illustrates a rear view of the exhalation pipe 700.
As shown, the end cap 715 includes exhalation vents 720.
[0065] FIGS. 9a-9e illustrate a pipe 900, in accordance with an
embodiment of the present invention. As will be described in more
detail below, the pipe 900 includes a combustion section, a filter
cartridge section, as well as an internal lighter section.
[0066] In some embodiments, the pipe 900 is about 4 inches tall
(top to bottom), 3 inches long (front to rear), and 7/8 inches wide
(left to right). As shown, the pipe 900 includes a body 910. A
mouthpiece 905 is rotatably attached to the front side of the body
910. A cap 915 is slidably mounted on the top of the body 905.
Sliding the cap 915 forward exposes the combustion bowl (not shown)
therein. Sliding the cap 915 towards the rear will allow the
mouthpiece 905 to flip open. In some embodiments, sliding the cap
forward after opening the mouthpiece secures the mouthpiece in its
open position. An ignition switch 920 ignites the internal lighter,
which causes combustible substance in the combustion bowl to
ignite. The smoker can inhale the smoke through the mouthpiece 905
via an inhalation path and exhale the smoke through the same
mouthpiece via an exhalation path to filter the smoke and odor.
[0067] FIG. 10a is an exploded view of the pipe 900, in accordance
with some embodiments of the present invention. The pipe 900
includes a body 1001 having three channels, namely, a front channel
1020, a center channel 1022, and a rear channel 1024. An exhalation
filter cartridge 203 is positioned in the center channel 1022. A
lighter 1004 is positioned in the rear channel 1024. A bottom cap
1012 with exhalation vents 1036 may be slidably mounted on the
bottom of the body 1001.
[0068] The front channel 1020 may be used for storage of
combustible substance. This storage may be locked in place using
spring-loaded ball bearings that drop into receiving indents on the
compartment. Some embodiments may use a swing out storage hinged
along the vertical edge of the compartment and the device. Other
embodiments may use a fold back compartment that is hinged at the
bottom of the compartment and device.
[0069] A fitting 1005 may be inserted into the top side of the body
1001, above the three channels. The fitting 1005 may include a
mouthpiece attachment portion 1026 in the front of the fitting
1005. A mouthpiece 905 and mouthpiece seal 1008 may be attached to
the mouthpiece attachment portion 1026. In some embodiments, the
mouthpiece seal 1008 includes five flat faces and one arcuate face.
The arcuate face may cooperate with an arcuate section of the
mouthpiece 905 to enable the mouthpiece 905 to rotate from a
position flush with the front face of the body 1001 to a position
normal to the front face of the body 1001. A pin (not shown) may be
slidably inserted through holes 1032 in the fitting 1002 and
through a pivot bore 1030 in the mouthpiece 905. When the
mouthpiece 905 is inserted into the body 1001, the dowel may be
held in place by the side walls of the body 1001.
[0070] The fitting 1002 may also include notches 1034, which abut
the top portion of the walls dividing the body 1001 into its three
channels. The notches 1034 may provide a better airtight seal
between the fitting 1002 and the body 1001. The fitting 1002 also
includes a combustion bowl 1028, possibly made of aluminum, with
flame access holes (not shown) on the bottom side of the bowl 1028.
The fitting 1002 may be attached to the body 1001, possibly using
glue, to provide an airtight seal.
[0071] A top lid 915 may be slidably attached to the fitting 1002
or the body 1001. A spring pin 1005, washer 1006 and set screw 1007
may cooperate with the top lid 915 to retain the lid 915 in open or
closed position. Some embodiments of the device may use a porcelain
lighter compartment top dome insert and a combustion chamber insert
to help contain heat generated during combustion.
[0072] An external ignition switch 920 may be slidably mounted
through the body 1001 to engage an internal ignition switch on the
lighter 1004. Upon activation, the lighter will ignite causing a
flame through the flame access holes under the combustion bowl
1028, causing the combustible substance to burn.
[0073] Like the pipe 100, the pipe 900 will include an inhalation
path from the combustion bowl through an inhalation filter to the
mouthpiece 905 and an exhalation path from the mouthpiece 905
through the exhalation filter cartridge 203 and out the exhalation
vents 1036.
[0074] FIG. 10b is an exploded view of a pipe 1050, in accordance
with an embodiment of the present invention. The pipe 1050 is
similar to the pipe 900 described above with reference to FIGS. 9
and 10a. In this case, pipe 1050 includes a body 1053 with no
channels therein. A storage chamber 1060, exhalation filter
cartridge 203, and lighter assembly 1004 are disposed into the body
1053 tightly against the inside walls of the body 1053 and tightly
against each other, thus dividing the body into three sections,
similar to the pipe 900. A fitting 1055 similar to fitting 1002 is
inserted above the three sections. Like the fitting 1002, the
fitting 1055 creates the channels for separate inhalation and
exhalation paths. The fitting 1055 supports mouthpiece 905, using
dowels 1062 and mouthpiece seal 1008. A bowl lid 1054, gasket 1056,
spring 1056 and pin 1058 cooperate to form a flip-top lid assembly
over the bowl 1028 in the fitting 1054. Lighter cap assembly 1068
is positioned at the bottom of the lighter assembly 1004 to enable
airflow, possibly one way, to the lighter assembly 1004 as needed
through a lighter vent 1070 in the bottom cap 1072. A top cover
wear-strip 1051 may be attached to the top cap 915 to enable the
top cap 915 to slide comfortably and not loosely across the top of
the body 1053 or fitting 1053. An ignition switch assembly
including ignition switch 920, ignition switch wear surface 1064
and slider block 1066, enables the user to ignite the lighter,
which burns the combustible substance.
[0075] FIG. 11a is a side view of the pipe 900, in accordance with
an embodiment. FIG. 11a defines plane A-A through the center of the
rear channel 1024 and plane B-B through the center of the center
channel 1022.
[0076] FIG. 11b is a sectional view of the pipe 900 at plane A-A.
As shown, the lighter 1004 is positioned within the rear channel
1024. Upon ignition, the lighter 1004 causes a flame 1138 to pass
through flame access holes 1180 in the combustion bowl 1028.
[0077] FIG. 11c is a sectional view of the pipe 900 at plane B-B.
As shown, the exhalation filter cartridge 203 is inserted into the
center channel 1022 above the exhalation vents 1036. The exhalation
filter cartridge 203 also cooperates with an intermediate channel
1140 from which it receives air exhaled from the smoker.
[0078] FIGS. 12a-12c illustrate the pipe 900, in accordance with
some embodiments. FIG. 12a is a front view of the pipe 900 and
defines a plane C-C through the center of the front face and a
plane H-H at about the 3/4 position of the front face from the left
side.
[0079] FIG. 12b is a sectional view of the pipe 900 at plane C-C.
As shown, a storage chamber 1020 is positioned in the front channel
1022, the exhalation filter cartridge 203 is positioned in the
center channel 1022, and the lighter 1004 is positioned in the rear
channel 1024 under the combustion bowl 1028. A one-way inhalation
valve 1205 is positioned between the combustion bowl 1028 to enable
smoke to transfer from the combustion bowl 1208 through the
intermediate channel 1210 to the mouthpiece 915. A one-way
exhalation valve 1215 may be positioned between the intermediate
channel 1210 and the center channel 1022 to enable exhaled smoke to
transfer from mouthpiece 915 through the intermediate channel 1210
to the center channel 1022 and exhalation filter cartridge 203 and
out the exhalation vents 1036. Alternatively or additionally, a
one-way exhalation valve 1215 may be positioned inside the
exhalation filter cartridge 203 as described below.
[0080] FIG. 12c is a sectional view of the pipe 900 at plane H-H.
As shown, the pin 1005 is positioned to lock the top lid 915.
[0081] FIG. 13 is a sectional side view of a pipe 1300, in
accordance with an embodiment of the present invention. As shown,
the pipe 1300 includes a mouthpiece 1302 in a pipe body 1301. The
mouthpiece 1302 is operatively coupled to an inhalation filter
1304, which is operatively coupled via a one-way inhalation valve
1308 to a combustion bowl 1306. A flip-top lid 1310 is positioned
over the combustion bowl 1306. The mouthpiece 1302 is also
operatively coupled to an exhalation filter channel 1318 with
exhalation filter media therein. An outlet cap 1320 with an
integral one-way exhalation valve is positioned at the bottom end
of the exhalation filter channel 1318. A lighter 1316 is positioned
in a channel below the combustion bowl 1306. The lighter 1316 may
receive air through a lighter air vent 1332 (possibly with a check
valve). An ignition switch 1314 extends through the pipe body 1301
to enable user activation of the lighter 1316. In one embodiment,
during an inhalation phase, the ignition switch 1314 is depressed
for one second before the person begins to inhale. During
inhalation, the smoke is drawn from combustion bowl 1306, through
the one-way inhalation valve 1308, through the inhalation filter
1304, and through the mouthpiece 1302. During exhalation, smoke is
past through the mouthpiece 1302, through the exhalation filter
channel 1318 (and exhalation filter media), and through outlet cap
1320. In some embodiments, the inhalation filter 1304 may be
replaced by removing the mouthpiece 105 and pulling on a cartridge
removal grip 1330 which protrudes into the mouthpiece 105.
[0082] FIG. 14 is a sectional side view of a pipe 1400, in
accordance with an embodiment of the present invention. As shown,
the pipe 1400 is similar to the pipe 1300, except with a timed
ignition button assembly 1405 and a lighter dust cover 1410. The
ignition button assembly 1405 ensures that the lighter is not on
too long to insure that the device does not generate enough heat to
be a source of injury. The lighter dust cover 1410 ensures that
dust does not impede ignition of the flame.
[0083] FIG. 15 illustrates details of the ignition button assembly
1405, in accordance with an embodiment of the present invention.
The ignition button assembly 1405 includes an external ignition
button 1505, a primary oil-filled chamber 1520, a transfer chamber
1510, and a return spring in the primary chamber 1520. As pressure
is applied to the external ignition button 1505, oil from the
primary chamber 1520 passes through holes 1530 in the plunger 1515
into the transfer chamber 1510, slowly releasing pressure on the
ignition switch 1505. Once the oil has traveled into the transfer
chamber 1510, the ignition switch 1505 is released and the oil is
allowed to return to the primary chamber 1520, whereby the process
may be repeated.
[0084] FIGS. 16a-16e illustrate the exhalation filter cartridge
203, in accordance with an embodiment. FIG. 16a is a perspective
view of the exhalation filter cartridge 203, which includes a front
face 1602, rear face 1604 and a central body 1606 (in this case,
with a square cross section). The front face 1602 includes an
opening 1608 for receiving the smoke and odor exhaled from the
smoker. In this case, the opening 1608 is round with a raised lip
1610 around the perimeter of the round opening 1608. The raised lip
1610 helps to create an airproof seal in the exhalation paths of
the pipes. FIG. 16b is a front view of the front face 1602 of
exhalation filter cartridge 203. FIG. 16c is a rear view of the
rear face 1604 of the exhalation filter cartridge 203. FIG. 16d is
a side view of the exhalation filter cartridge 203 and defines a
plane A-A and plane Z-Z. FIG. 16e is a sectional view of the
exhalation filter cartridge 203 at plane A-A. As shown, the
exhalation filter cartridge 203 includes opening 1608, filter media
1614, an end cap 1612, and filter exhalation vents 1616 in the end
cap 1612.
[0085] FIGS. 17a and b illustrate details of the exhalation filter
cartridge 203, in accordance with an embodiment of the present
invention. FIG. 17a is a sectional side view of the exhalation
filter cartridge 203. As shown, the exhalation filter cartridge 203
includes an inlet cap 1620, an outlet cap 1628, and a filter casing
1622 therebetween. The inlet cap 1620 includes a raised lip (or
"nipple") that engages a corresponding shape inside a pipe, so that
substantially all smoke exhaled passes through the filter media
1614. A pleated HEPA filter 1624 is positioned inside the
exhalation filter cartridge 203, between the inlet cap 1620, the
outlet cap 1628, and the filter casing 1622. HEPA material rated at
as little as a 95% rating will trap the smoke particles. A foam
core 1630 is positioned between the inlet cap 1620 and the outlet
cap 1628 and within the pleated HEPA filter 1624. For example, the
foam core 1630 may be manufactured from core of 60 pours-per-inch
(PPI can be higher or lower) polyether polyurethane foam (or other
foam).
[0086] FIG. 17b is a sectional view of the exhalation filter
cartridge 203 at plane Z-Z. As shown, the exhalation filter
cartridge 203 includes a foam core 1630, which is surrounded by the
pleated HEPA filter 1624, which is surrounded by the filter casing
1622. The foam core 1630 includes a central bore 1632, preferably
extending the length of the foam core 1630. The central bore 1632
allows the smoke to pass through the length of the foam core 1630,
before being forced laterally through the foam core 1630 and HEPA
filter 1624. Although not shown, a metal cap may be positioned at
the bottom end of the foam core 1630 and HEPA filter 1624 to stop
the downward flow of smoke and odor particles before being allowed
to exit out the outlet cap 1628, and to force the smoke and odor
particles laterally towards the filter casing 1622. The foam core
1630 may be infused with a odor capturing substance, e.g., odor
absorbing materials such as Ecosorb.RTM. odor-absorbing products
manufactured by OMI Industries. Citrus, mint and/or cinnamon
extracts (or other extracts) can additionally or alternatively be
added to the oil to provide a selection of scents.
[0087] In some embodiments, the odor absorbing materials react on a
molecular level to neutralize smoke odors, preferably involving
adsorption, absorption, gas solubility and reaction. For example,
when Ecosorb.RTM. oil is diluted with water and broadcast via
atomization, the tiny water droplets created contain a thin oil
skin that creates an electrostatic charge. This charge facilitates
adsorption of the odor molecules onto the droplet surface. The gas
is absorbed by the droplet (solubility) and held.
[0088] FIG. 18 is an exploded view of the exhalation filter
cartridge 203, in accordance with an embodiment of the present
invention. As shown, the exhalation filter cartridge 203 includes a
filter casing 1622. The inlet cap 1620 is positioned on the top
side of the filter casing 1622 to form the front face 1602. The
HEPA filter 1624 is positioned inside the filter casing 1622. An
internal filter cap 1802 is positioned on the bottom side of the
filter casing 1622 to support the HEPA filter 1624 and create an
exhalation hole 1806 to allow exhaled air to pass therethrough.
Although not shown, the foam core 1630 is positioned inside the
HEPA filter 1624. A flap 1804, possibly made of rubber (e.g.
Viton.RTM. rubber), is positioned on the bottom side of the
internal filter cap 1802 to cover the exhalation hole 1806. An
outlet cap 1628 is positioned over the internal filter cap 1802 and
the round flap 1804, supporting the round flap between the internal
filter cap 1802 and the outlet cap 1628. The outlet cap 1628
includes exhalation vents 1808 outside the boundaries of the flap
1804. Accordingly, during exhalation, air can pass through the
exhalation hole 1806, past the round flap 1804, and out the
exhalation vents 1808. During inhalation, the flap 1804 is drawn up
to cover the exhalation hole 1806, preventing air to flow through
the exhalation filter cartridge 203.
[0089] FIG. 19 is an exploded view of the exhalation filter
cartridge 203, in accordance with an embodiment of the present
invention. As shown, the exhalation filter cartridge 203 includes a
filter casing 1622. The inlet cap 1620 is positioned over the top
end of the filter casing 1622. A sponge foam seal 1904 may be
positioned over the inlet cap 1620 to enable an airproof seal with
the pipe body. The internal filter cap 1802 is positioned at the
bottom of the filter casing 1622. The flap is positioned over the
exhalation hole 1806. The outlet cap 1628 is positioned over the
internal filter cap 1802 and the outlet cap 1628. The foam core
1620 is positioned inside the pleated HEPA filter 1624, which is
positioned inside the filter casing 1622. The top of the HEPA
filter 1624 and foam core 1630 may be fused or glued to the inlet
cap 1620.
[0090] As stated above with reference to FIG. 18b, the foam core
1630 includes a central bore 1632, extending the length of the foam
core 1630. The central bore 1632 allows the smoke to pass through
the entire length of the foam core 1630, before being forced
through the foam core 1630 and HEPA filter 1624. A metal cap 1902
is positioned at the bottom end of the foam core 1630 and HEPA
filter 1624 to force the smoke laterally towards the filter casing
1622 before being allowed to exit out the outlet cap 1628. In this
embodiment, the metal cap 1902 is round and the cross section of
the filter casing 1622 is square. Accordingly, the metal cap 1902
forces the air to pass down the central bore 1632, laterally
through the foam core 1630, laterally through the HEPA filter 1624,
and out the corners that extend beyond the circumference of the
round metal cap 1902.
[0091] It will be appreciated that some embodiments may use natural
or synthetic fibers, ceramic, metal, chemicals, oils and/or
crystals for filtering.
[0092] FIGS. 20a-20d illustrate an exhalation filter cartridge 2005

2015 with a downward flanging tip 2030, a rear arm 2020, and a
pivot base 2025 between the two arms. Depressing the rear arm 2020
will cause the pivot base 2025 to pivot and the forward arm 2015 to
raise. FIG. 20c is a perspective view of the exhalation filter
cartridge 2005 positioned in the pipe 100. FIG. 20d is a close-up
of the retaining clip 2010 when the exhalation filter cartridge
2005 is positioned in the pipe 100. In this embodiment, the pipe
100 includes a hole 2035 configured to receive and retain the
downward flanging tip 2030 of the forward arm 2015, and a slot 2040
to receive the rear arm 2020. The pipe 100 also includes a recessed
portion 2045 to enable a user to apply downward pressure on the
rear arm 2020, when the exhalation filter cartridge 2005 is
positioned in the pipe 100. Other retaining clip options are
possible.
[0093] Some embodiments may use a warning system that will alert
the user and others that exhalation has not gone back through the
pipe. This alarm or alerting system will have an adjustable timer
of from 5 seconds to 30 seconds after which the alarm or alert will
sound. The use of this alarm or alerting system will assist in the
training of the user to always exhale through the device. Over
time, the proper use of this device will become habit.
[0094] The exhalation filter cartridge 203 may be designed to be
inserted into the series of devices.
[0095] Some embodiments may use filter media that is not in the
form of a cartridge.
[0096] Although several of the embodiments have been described as
using the same mouthpiece for inhalation and exhalation, one
skilled in the art will recognize that separate mouthpieces may be
used. Further, one skilled in the art will recognize that, in some
embodiments, the inhalation path and exhalation path may not
overlap.
[0097] The term "pipe" herein shall include various types of
smoking devices, including bongs, hookahs, cigarettes, cigars,
e-cigarettes, or the like.
[0098] It will be appreciated that smoke and odor may be visible or
invisible. It will be appreciated that the term "smoke" may or may
not include odor.
