Description
FIELD OF THE INVENTION
[0001] The present invention relates to an electronic cigarette
device, and in particular, to an electronic cigarette atomizing
core and an atomizer.
BACKGROUND OF THE INVENTION
[0002] The first electrode of the ultrasonic atomizing sheet of the
existing ultrasonic electronic cigarette atomizer is generally
connected to an electrode assembly by a wire, so the atomizing core
is inconvenient to assemble, and solder joints at two ends of the
wire easily fall off, resulting in poor conductivity of the
ultrasonic atomizing sheet. In addition, during ultrasonic
atomization, because the supply speed of e-liquid is slow, the
ultrasonic atomizing sheet is easily dry-burnt. Further, because
the air pipe is directly communicated with the atomization cavity,
the e-liquid splashed on the ultrasonic atomizing sheet enters the
vent tube connected with the suction nozzle during the atomization.
Hence, the user easily inhales the e-liquid.
SUMMARY OF THE INVENTION
[0003] The technical problem to be solved by the present invention
is to overcome the shortcomings of the prior art, and provide an
electronic cigarette atomizing core which is convenient to
assemble, does not require welding wires and can also protect the
ultrasonic atomizing sheet, and an atomizer.
[0004] In order to solve the above technical problems, the present
invention provides an electronic cigarette atomizing core,
including an outer sleeve and an inner sleeve which are sleeved on
each other, wherein an atomization cavity is formed below the inner
sleeve, and the outer sleeve is provided with a first e-liquid
passing port; two ends of e-liquid guide cotton are sandwiched
between the outer sleeve and the inner sleeve, and the two ends of
the e-liquid guide cotton cover the first e-liquid passing port;
the inner sleeve is provided with an air supply groove for
delivering air to an e-liquid tank, one end of the air supply
groove is communicated with the first e-liquid passing port, and
the other end thereof is communicated with the atomization
cavity.
[0005] In the present invention, the air supply groove is disposed
at a position corresponding to the first e-liquid passing port, and
the air supply groove is communicated with the atomization cavity,
so that a part of intake air flow entering the atomization cavity
can enter the e-liquid tank through the air supply groove and the
first e-liquid passing port. During smoking, the e-liquid tank
continuously supplies e-liquid, and a part of intake air flow in
the atomization cavity is continuously filled into the e-liquid
tank to increase the air pressure of the e-liquid tank, thereby
increasing the supply speed of e-liquid and effectively preventing
dry burning of the ultrasonic atomizing sheet.
[0006] Preferably, an inner cavity of the inner sleeve is provided
with a boss, for sealing and clamping a vent tube, and an air
outlet cavity sequentially from top down, so that the e-liquid
splashed during ultrasonic atomization is condensed on the inner
wall of the air outlet cavity, and the user hardly inhales the
e-liquid.
[0007] Preferably, the top of the inner sleeve is provided with two
vents symmetrically, the outer wall of the inner sleeve under the
two vents is respectively provided with a vent groove that reaches
the bottom of the inner sleeve, and after the outer sleeve and the
inner sleeve are sleeved on each other, the inner wall of the outer
sleeve and the vent grooves enclose two first air inlet channels.
The two first air inlet channels are symmetrically disposed on two
sides of the atomization cavity, and intake air flows through the
two first air inlet channels at equal quantity and equal velocity,
and flows into the atomization cavity from symmetrical positions on
two sides of the atomization cavity, so smoke in the atomization
cavity is taken away more thoroughly, and the smoke is prevented
from staying in the atomization cavity to affect the taste when
smoking next time.
[0008] Preferably, the outer wall of the inner sleeve is
symmetrically provided with e-liquid guide cotton mounting grooves
for mounting the two ends of the e-liquid guide cotton, the
e-liquid guide cotton mounting groove is provided with a clamping
segment at the upper part for clamping the e-liquid guide cotton
and a loosening segment at the lower part, and the depth of the
e-liquid guide cotton mounting groove at the clamping segment is
less than that of the e-liquid guide cotton mounting groove at the
loosening segment, so that the e-liquid guide speed of the e-liquid
guide cotton is not affected by clamping after the e-liquid guide
cotton is clamped and fixed.
[0009] Preferably, the e-liquid guide cotton mounting grooves and
the vent grooves are arranged alternatively to prevent the air flow
in the vent grooves from affecting the flow rate of e-liquid on the
e-liquid guide cotton, which then affects the atomization effect of
the ultrasonic atomizing sheet.

ultrasonic atomizing sheet, an elastic insulating seat and an
electrode assembly are sequentially disposed in the inner cavity of
the outer sleeve from top down; a first electrode is disposed on

ultrasonic atomizing sheet is electrically connected to the second
electrical connection terminal of the electrode assembly via the
outer sleeve, and the second electrode of the ultrasonic atomizing
sheet is electrically connected to the first electrical connection
terminal of the electrode assembly.
[0011] Preferably, the upper part of the inner wall of the outer
sleeve is provided with a support portion, the top of the outer
wall of the inner sleeve is provided with a step, and the step is
supported by the support portion, so that the inner sleeve and the
outer sleeve are fixedly connected into a whole.
[0012] Preferably, the lower part of the inner wall of the outer
sleeve is provided with a resisting portion for resisting the first
electrode of the ultrasonic atomizing sheet, which forms an
electrical connection. As such, the resisting portion of the outer
sleeve directly resists the first electrode of the ultrasonic
atomizing sheet, and the bottom of the inner wall of the outer
sleeve is directly connected to the electrode assembly, so the
electrical connection can be realized without wire bonding.
[0013] Preferably, a yielding portion for preventing the side wall
of the ultrasonic atomizing sheet from being broken due to
squeezing, surrounds the periphery of the resisting portion, so
that the assembled ultrasonic atomizing sheet is only subject to
the resisting force of the resisting portion, and the ultrasonic
atomizing sheet is conserved.
[0014] Preferably, the lower surface of the ultrasonic atomizing
sheet is disposed on the upper surface of the elastic insulating
seat, so as to prevent the ultrasonic atomizing sheet from being
broken by squeezing or losing its atomizing function by means of
the elasticity of the elastic insulating seat itself.
[0015] Preferably, the upper part of the inner cavity of the
elastic insulating seat is provided with a mounting portion, and
the ultrasonic atomizing sheet is mounted on the mounting portion
to prevent the side wall of the ultrasonic atomizing sheet to be
scratched or squeezed because of the shaking of assembled

locking leg movement grooves A14; when the e-liquid tank device A
is aligned with the suction nozzle device B, the buttons B41 are
clamped by the shell of the suction nozzle device B, and the two
limit bosses B21 are limited by the limit steps A131 at the ends of
the limit step movement grooves A13, so that the suction nozzle
device B cannot rotate relative to the upper cover A1; when the two
buttons B41 are simultaneously pressed down to break away from the
limitation of the shell of the suction nozzle device B, the locking
legs B411 break away from the limitations of the clamping grooves
A141; when the suction nozzle device B rotates 90 degrees
counterclockwise around the e-liquid tank device A, the locking
legs B411 rotate counterclockwise in the locking leg movement
grooves A14, and the limit bosses B21 rotate 90 degrees
counterclockwise in the limit step movement grooves A13 to open the
e-liquid filling port A12, which facilitates the filling of
e-liquid; then the suction nozzle device B rotates 90 degrees
clockwise around the e-liquid tank device A, the locking legs B411
rotate clockwise in the locking leg movement grooves A14 and are
finally snapped into the clamping grooves A141, the buttons B41 are
snapped into the shell of the suction nozzle device B, the limit
bosses B21 rotate 90 degrees clockwise in the limit step movement
grooves A13 and are finally limited by the limit steps A131 to
close the e-liquid filling port A12, and the suction nozzle device
B cannot rotate relative to the e-liquid tank device A.
