Description
CROSS-REFERENCE TO RELATED APPLICATION(S)
[0001] This application is a National Stage of International
Application No. PCT/CN2011/081661 filed Nov. 2, 2011, claiming
priority based on Chinese Patent Application No. 201110291841.9
filed Sep. 30, 2011, the contents of all of which are incorporated
herein by reference in their entirety.

particularly, to a bladeless fan.
DESCRIPTION OF RELATED ART
[0003] A general fan is composed of a fan frame, a driving motor
installed in the fan frame and rotatable blades connected the
driving motor. Generally, a blowhole in front of the blades is
covered by a protective cover for safety. As the protective cover
of the fan has a plurality of openings, it is possible that
children's fingers may be injured. In addition, since the general
fan creates airflow using blades, a strong air flow is generated
with inconsistent intensity so that the user may feel
uncomfortable. The blades have to be detached, re-assembled and
tested for cleaning, and the whole process causes huge
inconvenience to the user.
[0004] In order to solve the above problem, a blade-concealed fan
has been designed. The blade-concealed fan includes a body and an
blower having a blowhole in the front-end through which airflow
communicates, the body includes a body case having installed
therein blades and a motor, the motor drives the blades to rotate,
and an air suction hole is formed in the body case. The above fan
does not need outwardly-exposed blades and its function is only to
push airflow to circulate so that it fails to meet the recent
demand for a multifunctional device and leads to a less noticeable
practicality. In addition, control buttons of the conventional
electric fan of the related art are generally installed in the body
case so that the control buttons are not rotated in response to the
rotation of the body case. Hence, it is inconvenient to manipulate
the level of airflow intensity and to turn on/off the fan.

EXAMPLE 1
[0047] As shown in FIGS. 1 to 5, a bladeless fan according to an
exemplary embodiment of the present invention includes a base 2
configured to generate airflow and an blower 1 configured to
include a blowhole on the front-end to blow the airflow, the base 2
includes a rotating body 21 configured to generate the airflow and

by the motor 213, an air suction hole 3 is formed on the sidewall
of the rotation case 211, the fixed body 22 includes the fixation
case 221 and a synchronous driving mechanism 222 fixed on the top
of the fixation case 221 and configured to drive the rotation case
211 to horizontally rotate, and a touch screen controlling device 4

[0048] The touch screen controlling device 4 is installed in the
fixation case 221, the synchronous driving mechanism 222 of the
fixed body 22 drives the rotating body 21 and the blower 1 to
horizontally rotate back and forth. Even though an air blowing
direction changes, the touch screen controlling device 4 is not
rotated so that a signal receiving performance of the touch screen
controlling device is improved and advantages of simple
manipulation, more convenience and high practicality are
achieved.
[0049] As shown in FIG. 2, the blower 1 according to an exemplary
embodiment of the present invention includes a blower internal case
11 and a blower external case 12, the blower internal case 11 and
the blower external case 12 are bayonet-locked with each other,
both the blower internal case 11 and the blower external case 12
are in a ring or elliptical shape, and the blower 1 in a ring or
elliptical shape with a simple structure is easy to be formed,
keeps consistent intensity of wind and makes a user comfortable.
The blower 1 may be formed in other shapes as long as a blowhole is
installed between the blower internal case 11 and the blower
external case 12 so as to blow out airflow. Since the airflow is
forcibly blown out from the blowhole of the blower 1 with the
volume of the blown-out airflow increased up to 15 times and the
speed of up to 35 km, the blown out airflow is softer than that of
a conventional fan and a user may feel comfortable.
[0050] As shown in FIGS. 1 and 3, to be specific, the air suction
hole 3 is formed on the sidewall of the rotation case 211 in a
circumference direction, the blast area of the air suction hole 3
gradually decreases from the external to the internal, and the
largest blast area of the air suction hole 3 is 2 to 5 times

a consistent volume of air is absorbed and high practicality are
achieved.
[0051] As shown in FIG. 2, the rotating body 21 further includes a
motor base 214 configured to fix the motor 213, a motor auxiliary
base 215 configured to fix the motor base 214, a motor support 216,
a motor cover 217 configured to cover the top of the motor 213 and
a bracket 218 installed on the top of the motor cover 217, the
turbine 212 is installed between the motor auxiliary case 215 and
the motor support 216, and the motor support 216 is detachably

to each other through a hook, the motor 213 is inserted into the
motor base 214, the motor base 214 is inserted into a receiving
chamber of the motor auxiliary base 215, and the turbine 212 is
clamped between the motor auxiliary base 215 and the motor support
216 so that it results in a simple structure, easy detachment and
replacement of parts, more convenience in assembly, a more stable
structure and a high process efficiency.
[0052] Among them, a plurality of blades with the same shape and
structure are installed inside of the turbine 212, a plurality of
blades are arranged in a spiral fashion, the same interval is
formed between two adjacent blades, an air flux boosted using the
pressure intensifying principle of the turbine 212 goes through the
blower 1 so that the volume of the airflow in the blower 1
increases, resulting in a greater volume of the blown-out air and a
highly efficient blow effect.
[0053] Among them, the motor 213 is a direct-current brushless
motor in which parts are not damaged due to wearing of a carbon
brush, and the motor 213 makes less noise and is unlikely to break

mechanism 222 includes a synchronous rotatable plate 223 and a
synchronous bracket 224, the central parts of the synchronous
rotatable plate 223 and the synchronous bracket 224 are connected
to each other through a rotation shaft 225, a synchronous motor 226
is installed on the synchronous rotatable plate 223, an eccentric
shaft sheet 227 is installed on the synchronous bracket 224, an

[0055] The synchronous motor 226 leads the rotation shaft 225 via
the transmission metal sheet 229 to rotate, thereby making the
synchronous bracket 224 rotate around the rotation shaft 225 and,
in turn, leading the rotating body 21 and the blower 1 to
horizontally rotate. Specifically, the second eccentric shaft sheet
227 is connected to the rotation shaft 225 of the synchronous motor
226, and the second eccentric shaft 228 of the second eccentric
shaft sheet 227 is connected to the transmission metal sheet 229,

the bottom of the fixation case 221 so as to fix electrical cords
of the present invention, thereby preventing the cord from being
loosened due to repeatedly plugging and unplugging the cords and
leading to a significant reliability. At least two POM friction
plates 202 are installed on a surface where the synchronous
rotatable plate 223 and the synchronous bracket 224 are in contact
with each other and the POM friction plates 202 repeatedly rotate,
thereby preventing wearing of the synchronous rotatable plate 223,
extending the lifetime of the synchronous bracket 224 and the
synchronous rotatable plate 223, enhancing the wear property of the
synchronous bracket 224 and the synchronous rotatable plate 223 and
improving reliability.
[0057] As shown in FIG. 2, a touch screen controlling device 4
includes a touch screen bracket 41 installed on the sidewall of the
fixation case 221, a touch screen 42 installed on the touch screen
bracket 41 and the first Printed Circuit Board (PCB) 43 installed
on the bottom of the fixation case 221, and the first PCB 43 and
the touch screen 42 are electrically connected to each other. As
the touch screen controlling device 4 may be controlled not only by
a remote controller but also a user's hand so as to turn on/off the
fan or control an air-blowing direction or an air volume, a simple
manipulation method and significant practicality may be
achieved.
EXAMPLE 2
[0058] As shown in FIGS. 6 to 10, the present example is different
from the first example in that an atomizing device 5 is installed
below the fixed body 22 and that the atomizing device 5 and the
fixed body 22 are detachably connected to each other and that the
atomizing device 5 includes a water tank body, a ultrasonic
atomizer 52 connected to a water tank body, an air-blowing
mechanism 53, an atomizing mechanism installed above the ultrasonic
atomizer 52 and the second PCB 55 connected to the ultrasonic
atomizer 52 while the atomizing mechanism is installed in the
back-end of the blower 1 and the second PCB 55 and the touch screen
controlling device 4 are electrically connected to each other.
[0059] Resonance is generated through a vibration circuit and a
unique vibration frequency of a piezoelectric ceramic so that the
size of the liquid droplet atomized by the ultrasonic atomizer 54
which is in direct contact with the piezoelectric ceramic is
between 1 .mu.m and 3 .mu.m. The liquid droplets atomized using the
air-blowing mechanism 53 are evenly diffused into the air using an
atomizing mechanism, humidifies the air and generates an abundant
amount of anion so that the atmosphere becomes cleaner and better
for health.
[0060] In summer, installation of the atomizing device 5 reduces
indoor temperature so that indoor environments become cooler and
air-conditioners are used less, resulting in energy saving and less
electricity consumption. In winter, if the indoor environments are
too dry, it is possible to control the touch screen controlling
device 4 to operate only the atomizing device 5 for humidification,
leading to a more pleasant atmosphere and meeting the demand for a
multi-functional fan.
[0061] As shown in FIG. 10, the water tank body includes a water
tank case 510, a water tank lower case 511 configured to seal the
water tank case 510 and a bottom box 512 installed below the water
tank lower case 511, a water tank fixing part 513 is installed in
the water tank lower case 511, the ultrasonic atomizer 52 is
installed on the top surface of the bottom box 512, the second PCB
55 is installed on the top surface of the bottom box 512, the
air-blowing mechanism 53 includes a blow guide funnel 531 connected
to the atomizing mechanism and a fan 532 connected to the blow
guide funnel, the blow guide funnel 531 is fixed on the top surface
of the bottom box 512, the fan 532 is fixed on the bottom surface
of the bottom box 512, the atomizing mechanism includes a blowing
frame 541 installed on the top of the bottom box 512, the first
boss 542, an atomization tank 543 and an atomizing nozzle 544
connected to the atomization tank 543 and an atomizing ring 545
installed on the top of the atomizing nozzle 544, the first boss
542 and the atomization tank 543 are installed on the blowing frame
541 and connected to each other, the atomization tank 543 is
installed on the top of the ultrasonic atomizer 52 while facing
forward, the blowing frame 541 is connected to the water tank lower
case 511 through the first boss 542, the second boss 514 of the
water tank lower case 511 is sleeve-connected to the top of the
first boss 542, and the blowing frame 541 and the water tank case
510 are coupled into one set.
[0062] Liquid such as water may be filled in the water tank case
510 by opening the water tank fixing part 513, and the water tank
fixing part 513 may be used not only for filling but also emptying
the water tank case 510 so that a simple structure without a water
intake port and an easy process with reduced production costs may
be realized. Since the first boss 542 is configured to cover the
top of the blow guide funnel 531 and the second boss 514 is
sleeve-connected to the top of the first boss 542, the blowing
frame 541 is in a good position to from a rabbit joint with the
water tank case 510, the connection between the blowing frame 541
and the water tank body is fairly stable, the blowing frame 541
needs smaller space and a reasonable design with simple assembly
and disassembly methods is realized.
[0063] Specifically, the atomizing nozzle 544 includes a hose 5441
and a hard tube 5442, the hose 5441 is connected to the atomization
tank 543, the lower part of the hard tube 5442 is connected to the
upper part of the hose 5441 and the upper part of the hard tube
5442 is connected to the atomizing ring 545 so that it lead to a
stable connection between the atomizing nozzle 544 and the
atomization tank 543 and between the atomizing nozzle 544 and the
atomizing ring 545, a heightened airtight level, an extended
lifetime and improved durability. Among them, the atomizing ring
545 includes an atomization front case and an atomization back
case, an atomization area is formed between the atomization front
case and the atomization back case, and an atomizing direction in
the atomization area is the same as the air-blowing direction of
the blowhole of the blower 1 so that consistent atomization is
ensured with a significant atomization effect.
[0064] As shown in FIG. 10, a sensor-embedded supporting foot 9 is
installed inside of the bottom box 512 and a magnetic pole 10 is
installed on the top surface of the bottom box 512. Since the
sensor-embedded supporting foot 9 floats on the top surface of
liquid, the sensor-embedded supporting foot 9 goes down if the
amount of the liquid on the bottom box 512 is reduced, and, if
there is no liquid, raises an alarm for water shortage while
automatically stopping the atomization using the second PCB 55 at
the same time so that it prevents an operation in dry environments
and boasts great in-use stability.
[0065] As shown in FIG. 10, the water tank includes an external
case configured to cover an outside of the water tank case 510 and
a bottom plate 515 configured to fix the external case, the
external case includes a front case and a back case 516, the front
case includes a front door 517, one side of the front door 517 is
hinge-connected to the back case 516, the other side of the front
door 517 is magnetically connected to the back case 516, and the
water tank case 510 is exposed by opening the front door 517.
[0066] The magnetic connection is made by installing the first
magnet in the front door 517 and a magnet block 5161 in the back
case 516 to correspond to the position of the first magnet or by
using the front door 517 composed of magnetic materials and
installing at least one magnetic block 5161 in a point where the
back case 516 and the front door 517 are connected to each other.
Specifically, an arc-shaped protruding block 519 is installed at
the center of a point where the front door 517 and the back case
516 are magnetically connected so that the front door 517 is easily
open and the water tank case 510 is used conveniently. Desirably,
two magnetic blocks 5161 are necessary, and each of the two
magnetic blocks 5161 needs to be disposed above and below the
arc-shaped protruding block 519 of the back case 516 to correspond
to each other, thereby making it easy to open and close the front
door 517 and to use the front door 517. A transparent front door
window 518 is formed in the front door 517 and a scale is coupled
to the front door window 518 so that it is easy to check the amount
of water in the water tank case 510 and it is possible to avoid an
operation in dry environments due to water shortage, leading to
great in-use safety.
[0067] Among them, installation of the bottom plate 515 makes the
atomizing device 5 to stand stably and, specifically, a bobbin
spool is installed on a bottom surface of the bottom plate 515 so
as to make it convenient to put electrical cords under the bottom
plate 515, thereby leading to space saving, easy storage and simple
manipulating.
[0068] Description overlapped with that of the first example is
omitted for the sake of explanation.
EXAMPLE 3
[0069] As shown in FIGS. 1 to 3, the present example is different
from the second example in that an air suction hole bracket 6 is
installed between the rotating body 21 and the blower 1, that the
blower 1 and the air suction hole bracket 6 are hinge-connected,
that suction units 63 are formed below the air suction hole bracket
6, that the suction units 63 are detachably installed on the
rotation case 211, that the suction units 63 have a larger cross
sectional area than the bracket 218 and that the blower 1, the air
suction hole bracket 6 and the rotating body 21 form an airflow
passage.
[0070] The suction units 63 are detachably installed on the
rotation case 211, the caliber of the suction units 63 have the
same size as that of the rotation case 211 so as to ensure that, if
airflow is generated in the rotating body 21, the airflow smoothly
goes through the suction unit 63 into the air suction hole bracket
6, and the suction units 63 are installed on the left side and the
right side of the air suction hole bracket 6 to correspond to each
other so as to ensure that the same volume of air is absorbed
through the left side and the right side of the air suction hole
bracket 6, thereby leading to a consistent volume of the blown-out
air and a great blow effect. In the present example, the left side
and the right side of the air suction hole bracket 6 shown in FIG.
2 is referred to the left direction and the right direction,
respectively.
[0071] Specifically, the air suction hole bracket 6 includes the
first air duct bracket 61 and the second air duct bracket 62
detachably connected to the first air duct bracket 61, and the
first air duct bracket 61 is coupled with the second air duct
bracket 62 so that it is easy for disassembly and replacement and
simple to be processed with a significant process efficiency.
[0072] The air suction hole bracket 6 hinge-connected to the blower
1 makes it easy to adjust the air-blowing direction of the blower 1
through 360.degree. and to manipulate the blower 1, and helps a
user to flexibly change the swing angle of the blower 1 so that the
user may conveniently control the air-blowing direction as he/she
wishes.
[0073] As shown in FIG. 11, an angle position rings 7 are installed
on the outer sidewall of the blower 1, the angle position rings 7
are sleeve-connected to each end of the air suction hole bracket 6,
and the swing angle of the angle position ring 7 is between
20.degree. and 60.degree.. Specifically, the upper part of the
angle position ring 7 is in a semi-circular shape, an arc-shaped
protrusion is installed on the bottom of the angle position ring 7,
the swing angle of the blower 1 is determined according to a point
at which the arc-shaped protrusion of the angle position ring 7 is
connected to the inner side of the airflow passage of the blower 1
so that a change in the ventilating direction of the blower 1 due
to external force is prevented, thereby leading to a great position
effect, a fixed air-blowing direction and high practicality.
[0074] Other description of the present example overlapped with
that of the second example is not provided.
EXAMPLE 4
[0075] Like FIG. 2, the present example is different from the third
example in that an anion generating unit 8 connected to the first
PCB 43 is installed in the fixed body 22. The first PCB 43 and the
touch screen 42 are electrically connected so that the anion
generating unit 8 is performed by controlling the touch screen
using a remote controller or a user's touch, and anion generated by
the anion generating unit 8 goes into the blower 1 according to
high-speed airflow generated by high-speed rotation of the turbine
212 and then is blown out through the blowhole and spread into the
air so that the atmosphere may become clean, use convenience may be
improved, and the users' demand for multi-functions may be met.
[0076] Other description of the fourth example overlapped with that
of the third description will not be provided.
[0077] A number of examples have been described above.
Nevertheless, it should be understood that various modifications
may be made. For example, suitable results may be achieved if the
described techniques are performed in a different order and/or if
components in a described system, architecture, device, or circuit
are combined in a different manner and/or replaced or supplemented
by other components or their equivalents. Accordingly, other
implementations are within the scope of the following claims.
