Description
FIELD OF THE INVENTION
[0001] The present invention relates to electronic atomization
device and, in particular, it concerns an electronic atomization
device with an adjustable air inlet.
BACKGROUND OF THE INVENTION
[0002] Electronic atomization device, also called electronic
cigarette, atomization tobacco with low temperature, is mainly used
for reducing harms brought by smoking traditional cigarette. Its
appearance and taste are similar to cigarette and it has more
flavors than even normal cigarette does. It can also create a
cloud, a taste and a feel that resemble cigarette. The electronic
atomization device, which is composed of battery assembly and
atomizer, is an imitative cigarette, and flavor components therein
can be atomized into gas by atomization so that user can inhale it
directly. The flavor components include tobacco liquid, tobacco
shred, tobacco powder, tobacco paste, fragrant slice, fragrant bar,
liquid tobacco and so on.
[0003] The atomization device for atomizing the flavor components
generally includes an air inlet for inhaling the outside air which
will be mixed with the atomizing gas, and such an air inlet may be
an access for the condensate and liquid flavor flowing to the
outside world. Generally, the air inlet is arranged at the bottom
of the electronic atomization device and cannot be closed when not
in use, thus the condensate and liquid flavor are very easy to flow
to the outside surface of the electronic atomization device which
will cause the outside surface of the electronic atomization device
to be dirty. And if the condensate and liquid flavor enter into the
inside of the battery assembly via the air inlet, the battery
assembly may be damaged.
SUMMARY OF THE INVENTION
[0004] An object of the present invention is to overcome the
defects of the prior art by providing an electronic atomization
device with an adjustable air inlet, which can prevent the
condensate and liquid flavor from flowing out of the electronic
atomization device via the air inlet, so as to avoid the outside
surface of the electronic atomization device getting dirty and
reducing the possibility of damaging the battery assembly.
[0005] To achieve the above object, the following technical
solutions are provided:
[0006] There is provided an electronic atomization device with an
adjustable air inlet, which includes a cigarette holder, an
atomizer connected to the cigarette holder and a battery assembly
for supplying power to the atomizer. The device further includes an
air inlet disposed at an upper portion of the atomizer for
connecting the atomizer to outside world and a switch assembly
disposed between the atomizer and the cigarette holder for opening
or closing the air inlet.
[0007] Preferably, the switch assembly includes a round ring
sandwiched between the atomizer and the cigarette holder and a
sealing block fixed inside the round ring for opening or closing
the air inlet, the round ring being coaxial with the atomizer, and
when the round ring rotates with respect to the atomizer, the air
inlet will be opened or closed by the sealing block which is driven
by the round ring.
[0008] Preferably, there is provided a flange disposed inside the
round ring and the sealing block is fixed on the flange.
[0009] Preferably, there are provided a limiting notch formed at
the flange and a limiting pillar disposed at the top of the
atomizer and extending throughout the limiting notch. Due to the
assembly relation between the limiting notch and the limiting
pillar, the rotation range of round ring will be restricted,
thereby avoiding the sealing block far away from the air inlet
which will bring inconvenience to use.
[0010] Preferably, the round ring has an inlet notch formed at the
bottom thereof and the air inlet connects to the outside world via
the inlet notch.
[0011] Preferably, the round ring has ant-slip strips formed on an
outside surface thereof.
[0012] Preferably, the sealing block is an elastic sealing
block.
[0013] Preferably, the sealing block contacts with an upper surface
of the air inlet, and the upper surface of the air inlet is an
inclined surface so that the sealing block is capable of applying
pressing force onto the upper surface of the air inlet when the air
inlet is closed completely by means of the sealing block.
[0014] Preferably, the switch assembly further includes an elastic
pad disposed between the sealing block and the air inlet, and the
elastic pad has a through hole corresponding to the air inlet.
[0015] Preferably, a concave is formed around the air inlet for
positioning the elastic pad and a convex corresponding to the
concave is provided at the bottom of the elastic pad, and the

ensure the function of opening and closing the air inlet.
[0016] Preferably, the sealing block and the round ring form an
integrated body and the sealing block has a blind hole formed on an
upper surface thereof. The blind hole is used for distinguishing
the installation direction of the round ring when assembling.
[0017] Preferably, the atomizer has a limiting cylinder formed on
the top thereof and the limiting cylinder has a notch formed
thereon for restricting the rotation range of the sealing
block.

series with the battery and an adjusting knob by which a resistance
value of the adjustable resistor is capable of being changed so as
to adjust the voltage applied on the atomizer.
[0024] Preferably, the voltage adjusting unit further includes a
connecting sleeve for determining a relative location between the
adjustable resistor and the adjusting knob; the adjusting knob has
a central shaft for connecting with the adjustable resistor; the
central shaft is clamped by the connecting sleeve and capable of
rotating with respect to the connecting sleeve and the adjustable
resistor is fixed on a circuit board which is clamped by the
connecting sleeve.
[0025] Preferably, the battery assembly further includes a casing
for containing the battery and the voltage adjusting unit further
includes a fixed round ring by which the connecting sleeve is fixed
to the casing; the fixed round ring is disposed on an outside
surface of the connecting sleeve and fixed to an inner surface of
the casing by an interference fit.
[0026] Compared with the prior art, the present invention has
beneficial effects as follows:
[0027] As disclosed in the present invention, the electronic
atomization device has an air inlet disposed at the upper portion
of the atomizer but not at the lower portion thereof, which can

out of the electronic atomization device when the electronic
atomization device dumping. Moreover, the air inlet can be closed
completely by means of the switch assembly thereby preventing the
condensate and liquid flavor from flowing to the outside world,
avoiding the outsider surface of the electronic atomization device
getting dirty and reducing the possibility of the damage of the
battery assembly.
