storage tube 20 and the base assembly 10 form a liquid storage
chamber 21 for storing the e-cigarette liquid (as shown in FIG. 7).
The atomizing core assembly 30 is received in the liquid storage
chamber 21 for atomizing e-cigarette liquid. The upper cover
assembly 40 is disposed at one end of the liquid storage tube 20
opposite to the base assembly 10, and is selectively in
communication with the atomizing chamber 310 and the liquid storage
chamber 21, so as to facilitate the user to inhale the smoke formed
after the atomization. When the upper cover assembly 40 is in
airflow communication with the atomizing chamber 310. When the
upper cover assembly is in airflow communication with the liquid
storage chamber 21, the air pressure in the liquid storage chamber
21 can be kept stable, the liquid leakage is prevented, and it's
convenient for the user to fill the e-cigarette liquid. The
mouthpiece is detachably disposed on the upper cover assembly 40
for the user to inhale the smoke formed after the atomization.
[0048] Referring to FIG. 3, specifically, the base assembly 10 is
substantially hollow cylindrical, the base assembly 10 includes a
base 11 with an inner chamber 110 and an air conditioning ring 13.
The base 11 has a substantially hollow cylindrical shape, an air
inlet 112 communicating with the inner chamber 110 is defined in a
circumferential wall of the base 11. The air distribution ring 13
is circumferentially rotatably sleeved on the outer circumference
of the base 11 and has an air conditioning groove 130 in
communication with the outside, the air conditioning groove 130 can
be in communication with or staggered from the air inlet 112. When
the air distribution ring 13 is rotated, the communication area
between the air conditioning groove 130 and the air inlet 112 can
be adjusted, so that the user can adjust the amount of the air
intake as needed.
[0049] The liquid storage tube 20 is a hollow sleeve, two ends of
the liquid storage tube 20 are throughout. Optionally, the liquid
storage tube 20 is a glass tube or a stainless steel tube, which is
sleeved outside the base 11, the liquid storage tube 20 and the
base 11 together form a liquid storage chamber 21 for storing
e-cigarette liquid.
[0050] Referring to FIG. 4, the atomizing core assembly 30 is
received in the liquid storage chamber 21. The atomizing core
assembly 30 includes an atomizing tube 31, a heat generating member
(not shown), a liquid guiding member (not shown) and an electrode
contact assembly 33. The atomizing tube 31 has openings at the
upper and lower ends, an atomizing chamber 310 is formed in the
atomizing tube 31. The atomizing tube 31 is provided with a liquid
inlet hole 312 communicating between the atomizing chamber 310 and
the liquid storage chamber 21. The heat generating member and the
liquid guiding member are disposed in the atomizing tube 31 for
sucking the e-cigarette liquid in the liquid storage chamber 21 and
heating and atomizing the e-cigarette liquid using the electric
power from the battery device. The heating element can be a heating
wire, the liquid guiding piece can be a liquid guiding cotton; the
arrangement of the two can be that the liquid guiding cotton is
wrapped around the heating wire, or the heating wire is wound
around the liquid guiding member. The electrode contact assembly 33
is disposed at the bottom of the atomizing tube 31, one end is
electrically connected to the heat generating member, the other end
is electrically connected to the battery device to provide
electrical power to the atomizing core assembly 30.
[0051] The external air enters the inner chamber 110 of the base 11
from the air conditioning groove 130 of the air distribution ring
13 and the air inlet 112 of the base 11, and then enters the
atomizing chamber 310 from the lower end of the atomizing tube 31.
The e-cigarette liquid in the atomizing chamber 310 is atomized to
form smoke, the external air and the smoke pass through the top of
the atomizing tube 31 and the upper cover assembly 40, and then
flow into the mouthpiece for the user to inhale.
[0052] Referring to FIGS. 5 and 6, the upper cover assembly 40
includes an upper cover 41 and a liquid injecting cover 43 that can
move relative to the upper cover 41 between the locking position
and the unlocking position. The upper cover 41 is sequentially
provided with a smoke outlet 410 and a liquid injecting port 412
along the movement path of the liquid injecting cover 43 from the
locking position to the unlocking position, the liquid injecting
cover 43 is provided with a through hole 430. When the liquid
injecting cover 43 is in the locking position relative to the upper
cover 41, the liquid injecting cover 43 is covered on the upper
cover 41 and cannot be rotated relative to the upper cover 41, the
through hole 430 is in communication with the smoke outlet 410, the
liquid injecting port 412 is closed. When the liquid injecting
cover 43 is moved from the locking position to the unlocking
position with respect to the upper cover 41 by an external force,
the liquid injecting cover 43 can be turned over and opened with
respect to the upper cover 41, and then the liquid injecting port
412 is exposed.
[0053] In this way, when the electronic cigarette is in use, the
through hole 430 of the liquid injecting cover 43 is located at the
locking position and in communication with the smoke outlet 410, so
that the e-cigarette liquid in the atomizing chamber 310 flows out
through the through hole 430 for the user to inhale; at this time,
the liquid injecting port 412 is closed, and the liquid injecting
operation cannot be performed. When the liquid filling operation is
required, the through hole 430 is translated from the locking
position to the unlocking position by the lateral push, and can be
opened by rotating relative to the upper cover 41 to expose the
liquid injecting port 412 to ensure the air pressure in the liquid
storage chamber 21 is stabilized by pre-relieving, so as to avoid
the liquid leakage caused by the change of the air pressure in the
liquid storage chamber 21 due to the sudden opening of the liquid
injecting cover 43, and the liquid injecting operation can also be
performed at the same time.
[0054] Specifically, the upper cover 41 includes a bottom cover 414
and a gland 416 disposed above the bottom cover 414. The smoke
outlet 410 and the liquid injecting port 412 are sequentially
defined on the bottom cover 414 along the moving path of the liquid
injecting cover 43 from the locking position to the unlocking
position. The bottom cover 414 is disposed at one end of the liquid
storage tube 20 away from the base assembly 10, a surface of the
bottom cover 414 facing away from the gland 416 is convexly formed
with a connection fixing post 4141 having a hollow structure. The
connection fixing post 4141 is inserted at an end of the atomizing
tube 31 away from the base 11 for fixing the upper cover assembly
40 and the atomizing core assembly 30 to allow the smoke in the
atomizing chamber 310 to flow. In addition, the upper cover 41
further includes a sealing ring 418 disposed between the bottom
cover 414 and the liquid storage tube 20 for preventing leakage of
e-cigarette liquid.
[0055] The edge of one side of the gland 416 is recessed inwardly
to form a notch 4161 that is open at one end and having a U-shaped
structure, both the smoke outlet 410 and the liquid injecting port
412 are received in and exposed in the notch 4161. Specifically,
the notch 4161 includes a connecting wall 4162 located at a side of
the smoke outlet 410 away from the liquid injecting port 412 and
two side walls 4164 connected to opposite ends of the connecting
wall 4162 and extending in the same direction. The surface of the
connecting wall 4162 near the bottom cover 414 is further recessed
to form a recess 4166 in a direction away from the smoke outlet
410, so that a receiving gap having a certain height is formed
between the gland 416 and the bottom cover 414. And, the surface of
the two side walls 4164 connected to the connecting wall 4162 is
recessed in a direction away from the bottom cover 414 to form a
translating groove 4165, the translating groove 4165 is in
communication with the notch 4161 and the recess 4166. At this
time, the two translating grooves 4165 are in communication with
the recess 4166 to form a U-shaped groove that surrounds the
outside of the notch 4161 and has the same opening direction as the
opening of the notch 4161.
[0056] One end of the liquid injecting cover 43 is received and
confined in the recess 4166 when the liquid injecting cover 43 is
in the locking position, and when the end of the liquid injecting
cover 43 is moved from the locking position to the unlocking
position, the liquid injecting cover 43 can be moved out of the
recess 4166 along the translating groove 4165 and turned over.
Specifically, the liquid injecting cover 43 includes a cover body
433 and a rotating shaft 431 protruding from opposite sides of one
end of the cover body 433. The cover body 433 has a substantially
rectangular plate shape, and its shape matches the shape of the
notch 4161. The through hole 430 extending through the cover body
433 has a hole wall protruding from the surface of the cover body
433 facing away from the bottom cover 414. When the liquid
injecting cover 43 is in the locking position, the rotating shaft
431 is locked in the recess 4166, the hole wall of the through hole
430 abuts against the recess wall of the recess 4166, thereby
preventing the gland 416 from being reversed about the rotating
shaft 431. When the liquid injecting cover 43 is moved from the
locking position to the unlocking position by an external force,
referring to FIG. 6, the rotating shaft 431 moves along the
translating groove 4165 and moves out of the recess 4166, so that
the hole wall of the through hole 430 and the recess walls of the
recess 4166 forms a rotational space for the cover body 433 to be
turned about the rotating shaft 431 with respect to the upper cover
41. At this time, the upper cover 41 can be opened by inverting the
liquid injecting cover 43, so that the liquid injecting port 412 is
exposed, the user can perform the liquid injecting operation. The
liquid injecting cover 43 can also be relatively closed on the
upper cover 41 after the liquid injecting operation is completed,
and then pushed back to the locking position from the unlocking
position. Throughout the process, the cover body 433 cannot be
flipped directly when in the locking position, it is necessary to
perform the lateral push to cancel the interference between the
cover body 433 and the gland 416, so as to realize flipping of the
cover body 433, thus the liquid injecting cover 43 is prevented
from being opened during the use of the electronic cigarette, and
provides with a child protection function at the same time.
[0057] The liquid injecting cover 43 includes a covering portion
432 disposed on the other end of the cover body 433 opposite to the
rotating shaft 431. The covering portion 432 extends to both sides
with respect to the cover body 433, and has a width in the
circumferential direction of the gland 416 greater than the width
of the notch 4161. In the specific embodiment, the covering portion
432 has a fan shape that extends toward the both sides of the cover
body 433. At the same time, the bottom of the gland 416 on both
sides of the notch 4161 is provided with a locking groove 4163 in
communication with the notch 4161, the width of the locking groove
4163 in the circumferential direction of the gland 416 is larger
than the width of the notch 4161. That is, the locking groove 4163
and the notch 4161 form a stepped groove with a wider upper part
and a narrower lower part. Thus, when the liquid injecting cover 43
is pushed into the locking position relative to the upper cover 41,
the covering portion 432 is received in the locking groove 4163 and
resists the groove wall of the locking groove 4163 to prevent the
liquid injecting cover 43 from being pushed in continuously. When
the liquid injecting cover 43 is pushed out to the unlocking
position relative to the upper cover 41, the covering portion 432
can be removed out of the locking groove 4163 through the opening
of the locking groove 4163, so that the liquid injecting cover 43
can be reversed relative to the upper cover 41.
[0058] In the embodiment, the liquid injecting port 412 is a
circular arc shape surrounding the partial outer circumference of
the smoke outlet 410. While matching the shape of the covering
portion 432 having a scalloped structure, the size of the liquid
injecting port 412 is increased to facilitate the liquid injecting
operation.
[0059] Further, in order to ensure the tightness between the gland
416 and the liquid injecting cover 43, a sealing groove 4143 is
defined in the bottom cover 414 around the smoke outlet 410 and the
liquid injecting port 412. The upper cover assembly 40 includes a
gasket 45, the gasket 45 is housed in the sealing groove 4143 and
sealed around the outer periphery of the smoke outlet 410 and the
liquid injecting port 412.
[0060] Referring to FIG. 7 together, in the specific embodiment,
the upper cover 41 includes a pin 417, the pin 417 passes through
the bottom cover 414 from below and is fixed on the gland 416, thus
to secure the bottom cover 414 and the gland 416. It is to be
understood that in other embodiments, the fixing manner of the
gland 416 and the bottom cover 414 can be changed as needed, or the
two can be integrally provided, which is not limited herein.
[0061] When the liquid injecting cover 43 of the electronic
cigarette of the present invention is in the locking position, the
liquid injecting cover 43 is covered on the upper cover 41 and
cannot be turned over with respect to the upper cover 41, the smoke
outlet 410 is in communication with the through hole 430, the
liquid injecting port 412 is closed; at this time, the smoking
operation can be performed normally and the liquid injecting
operation cannot be performed. When the remaining amount of the
e-cigarette liquid in the electronic cigarette is insufficient, the
liquid injecting cover 43 can be translated from the locking
position to the unlocking position to open the liquid injecting
cover 43 by turning over to completely expose the liquid injecting
port 412 for convenient operation. During the operation, the liquid
injecting cover 43 can be turned over after being pushed out
relative to the upper cover 41, and cannot be directly turned over.
While directly pushing laterally the liquid injecting cover 43, the
covering portion 432 is still covering the liquid injecting port
412, that is, the separate turning over or pushing laterally will
not expose the liquid injecting port, the infusion port must be
opened by a two-step operation with a push in the lateral direction
and a turning over, so it can be child proof.

present embodiment, the clamping portion 4191 and the resisting
portion 4192 are an integrally formed stainless steel elastic
piece, it is understood that other elastic members such as springs
are also applicable.
[0072] The liquid injecting cover 43 includes a cover body 433 and
a locking member 434 disposed under the cover body 433.
[0073] Specifically, the cover body 433 has a substantially
disk-like structure, the through hole 430 is defined at the center
of the cover body 433, the hole wall of the through hole 430
extends away from the upper cover 41 to form the plug portion 4331.
The mouthpiece 50 is sleeved on the plug portion 4331.
[0074] The locking member 434 is generally a plate having a round
structure. The locking member 434 is fixedly mounted on the surface
of the cover body 433 facing away from the mouthpiece 50, when the
liquid injecting cover 43 is in the locking position, the locking
member 434 can be sealed on the liquid injecting port 412, thereby
closing the liquid injecting port 412. The locking member 434 is
provided with an alignment hole 4341 corresponding to the through
hole 430. When the locking member 434 is connected to the cover
body 433, the alignment hole 4341 is in communication with the
through hole 430. In this embodiment, the locking member 434 is
inserted on the cover body 433. It can be understood that in other
embodiments not shown, the locking member 434 can also be connected
to the cover body 433 by means of a snapping or glue connection, or
the locking member 434 is integrally formed with the cover body
433, and is not limited herein.
[0075] In order to secure the sealing of the liquid injecting port
412 locked by the locking member 434, the outer periphery of the
liquid injecting port 412 is provided with a gasket 45.
[0076] The first connecting member 4342 is protruded from the
surface of the locking member 434 facing away from the cover body
433 and is disposed adjacent to the socket 4154 of the stopping
member 415. The first connecting member 4342 extends away from the
end of the locking member 434 to form an outwardly extending claw
4343. The surface of the claw 4343 facing away from the locking
member 434 is recessed with a latching groove 4344 that cooperates
with the projection 4181, the claw 4343 can be inserted into the
cavity 4153 via the socket 4154. When the locking member 434 is
translated, the claw 4343 can be moved in the cavity 4153 driven by
the locking member 434, so that the projection 4181 is caught in
the latching groove 4344. In this embodiment, the second connecting
portion 421 includes a first connecting member 4342, and further
includes a claw 4343, still further includes a latching groove
4344. When the liquid injecting cover 43 is in the locking
position, the first connecting portion 422 is locked with the
second connecting portion 421. When the projection 4181 is snapped
into the latching groove 4344, the peripheral edge of the socket
4154 abuts against the claw 4343, thereby restricting the action of
the locking member 434 being reversed relative to the upper cover
41. In the present embodiment, the projection 4181 is made of an
elastic material, the projection 4181 is deformed to be caught in
the latching groove 4344.
[0077] It will be appreciated that in other embodiments not shown,
the claw 4343 is made of an elastic material. The claws 4343 are
deformed such that the projection 4181 can snap into the latching
groove 4344. Of course, it is also understood that, in other
embodiments not shown, the first connecting portion 422 and the
second connecting portion 421 are provided with a magnetic member,
such as a magnet, respectively. When the liquid injecting cover 43
is in the locking position, the first connecting portion 422 is
magnetically coupled to the second connecting portion. Further, the
second connecting portion 421 includes a claw 4343, the claw 4343
itself is a magnetic member or a magnetic member is disposed
thereon. The first connecting portion 422 includes a fastening
member 420 and a projection 4181, the projection 4181 is provided
with a magnetic member such as a magnet. When the claw 4343 is
moved into position, the magnetic member on the claw 4343 and the
magnetic member of the projection 4181 are attracted to each other,
thereby locking the locking member 434, so that the sealing between
the liquid injecting cover 43 and the upper cover 41 is stronger.
When the liquid injecting cover 43 is in the unlocking position,
the first connecting portion 422 is disengaged from the second
connecting portion 421, the circumference of the socket 4154 no
longer resists the claw 4343, so that the liquid injecting cover 43
can be reversed. It can be understood that in other embodiments,
the first connecting portion 422 and the second connecting portion
421 can adopt other shapes and connections, for example, the first
connecting portion 422 and the second connecting portion 421 both
include a claw 4343, the claw 4343 of the second connecting portion
421 has the same shape as that in the present embodiment, the first
connecting portion 422 inverts the claw 4181 and engages with the
claw 4343 of the second connecting portion 421.
[0078] The second connecting member 4345 is protruded from the
surface of the locking member 434 away from the cover body 433 and
is adjacent to the limiting groove 4155 of the stopping member 415.
One end of the second connecting member 4345 away from the locking
member 434 extends outward to form a limiting member 4346. The
limiting member 4346 cooperates with the limiting groove 4155 and
can slide in the limiting groove 4155. A pivotal holes 4347 is
disposed on the side wall of the limiting member 4346 in the
sliding direction of the limiting member 4346. In the embodiment,
the liquid injecting cover 43 further includes a rotating shaft
431, the rotating shaft 431 is mounted in the pivotal hole 4347 and
slidably fitted in the translating groove 4156. When the rotating
shaft 431 is moved to the end of the translating groove 4156 away
from the socket 4154, turning over the liquid injecting cover 43,
the liquid injecting cover 43 can be rotated relative to the upper
cover 41 with the rotating shaft 431 as a center of rotation. It
should be noted that when the rotating shaft 431 is at any position
in the translating groove 4156, the clamping portion 4191 of the
elastic member 419 is elastically resisted on the limiting member
4346.
[0079] Referring to FIG. 13 and FIG. 14 simultaneously, when the
user needs to inject liquid, the liquid injecting cover 43 is first
pushed toward the unlocking position, so that the locking member
434 moves under the force of the liquid injecting cover 43 to
unlock the first connecting portion 422 and the second connecting
portion 421, for example, the latching groove 4344 of the claw 4343
is disengaged from the projection 4181. When the claw 4343 is
aligned with the socket 4154, at this time, the rotating shaft 431
just moves to the end of the translating groove 4156 away from the
socket 4154, and the liquid injecting cover 43 is in the unlocking
position; then, the liquid injecting cover 43 is turned over, so
that the liquid injecting port 412 is exposed and opened, and the
user can perform the liquid injecting operation. Referring to FIG.
12, when the user finishes the injection and needs to close the
injection port 412, the liquid injecting cover 43 is first turned
over, so that the claw 4343 is received in the cavity 4153 via the
socket 4154, and the liquid injecting cover 43 is in the unlocking
position, and then the liquid injecting cover 43 is pushed evenly
toward the locking position, so that the latching groove 4344 and
the projection 4181 are engaged with each other, and the peripheral
edge of the socket 4154 abuts the claw 4343, thereby restricting
the movement of the locking member 434 relatives to the upper cover
41, that is, the liquid injecting cover 43 cannot be reversed with
respect to the upper cover 41. At this time, the liquid injecting
cover 43 is in the locking position, the first connecting portion
422 is locked to the second connecting portion 421, the liquid
injecting cover 43 is placed on the upper cover 41, the liquid
injecting port 412 is closed, the user can inhale, and the liquid
filling operation cannot be performed.
[0080] It should be noted that, in this embodiment, when the liquid
injecting cover 43 is in the locking position, on the one hand, due
to the resistance of the elastic member 419 to the limiting member
4346, on the other hand, due to the locking of the latching groove
4344 and the projection 4181, the liquid injecting cover 43 is
always maintained in the locking position, and the situation that
the liquid injecting cover 43 is slid to the unlocking position due
to the small locking force is avoided. It can be understood that,
in other embodiments not shown, retaining one of the following
structure, the engagement structure of the latching groove 4344 and
the projection 4181, or the elastic member 419, can also prevent
the liquid injecting cover 43 from sliding freely.
[0081] In the electronic cigarette according to the second
embodiment of the present invention, compared with the first
embodiment, the position of the liquid injecting port 412 on the
bottom cover 414 can be unrestricted, which is convenient for
production. By combining the horizontal pushing operation and the
flipping operation, the liquid injecting port 412 can be opened to
completely expose the liquid injecting port 412 for convenient
operation. Meanwhile, by providing the clamping structure of the
projection 4181 and the latching groove 4344, thus that the sealing
between the liquid injecting cover 43 and the upper cover 41 more
firmly.
[0082] The above-mentioned embodiments merely represent several
implementations of the present application, and the descriptions
thereof are more specific and detailed, but they shall not be
understood as a limitation on the scope of the present application.
It should be noted that, for those of ordinary skill in the art,
variations and improvements may still be made without departing
from the concept of the present application, and all of which shall
fall into the protection scope of the present application.
Therefore, the scope of protection of the present application shall
be subject to the appended claims.
