The pressing member 233 and the inner wall of the second liquid guide hole 231 define a path through which the liquid medium flows in the second liquid guide hole 231. In other embodiments of the present invention, the second liquid guiding hole 231 may be defined by the pressing member 233 itself, and specifically, a through hole (not shown) may be formed in the pressing member 233 and is communicated with the liquid outlet pipe 120, so that after the pressing member 233 presses the first sealing member, the liquid matrix flows along the through hole to the atomizing core 25 through the third liquid guiding hole 241 for atomization.

In summary, since the atomizing assembly 20 has the first and second mounting positions with respect to the reservoir 10, the nebulizer 100 can have two states, namely, a pre-installed state and a usage state, in which the atomizing assembly 20 and the reservoir 10 are kept connected. When the atomizing assembly 20 is connected to the reservoir 10 in the first assembled position, the atomizer is in the pre-loaded state; when the atomizing assembly 20 is moved from the first assembled position to the second assembled position with respect to the reservoir 10, the atomizer is in use.

In the pre-assembled state, i.e., when the atomizing assembly 20 is connected to the reservoir 10 in the first assembled position, the atomizing assembly 20 is not tightly coupled to the reservoir 10, and a gap 50 exists, and the pressing member 233 is spaced apart from the first sealing member, which has not been broken or loosened, and the liquid medium is sealed in the reservoir cavity of the reservoir 10 and is separated from the atomizing core 25 of the atomizing assembly 20, as shown in fig. 8. It will be readily appreciated that in other embodiments of the utility model, the pressing member 233 may also abut the first sealing member in the pre-installed state, as long as the first sealing member is not unsealed in the pre-installed state.

In a use state, that is, when a user is ready to use the atomizer 100 for inhalation, the user can apply pressure to the reservoir 10 to move the atomizing assembly 20 relative to the reservoir 10 from the first assembly position to the second assembly position under the action of external force, at which time the atomizing assembly 20 is tightly combined with the reservoir 10, and the pressing member 233 further presses the first sealing member, so that the first sealing member is broken or loosened, and thus the liquid matrix in the reservoir 10 flows to the atomizing core 25 in the atomizing assembly 20 for atomization.

In this way, compared with the prior art in which the liquid matrix in the liquid reservoir 10 is in direct contact with the atomizing core 25, the atomizer 100 provided by the embodiment of the present invention is separated from the atomizing core 25 before the atomizer 100 is used for suction, wherein the liquid matrix in the atomizer 100 is sealed in the liquid reservoir 10; when in use, the cigarette is unpacked and is contacted with the atomizing core 25, thereby greatly reducing the contact time of the liquid matrix and the atomizing core 25 and effectively preventing the smoke from leaking.

Meanwhile, the atomizer provided by the embodiment of the application is provided with the second sealing piece on the atomization assembly, when the liquid reservoir is connected with the atomization assembly, the extrusion component of the atomization assembly provides extrusion force for the first sealing piece of the liquid reservoir, so that the first sealing piece is broken or loosened, the liquid matrix in the liquid reservoir flows to the liquid inlet of the atomization assembly from the liquid outlet of the liquid reservoir, the second sealing piece provides sealing at the joint of the liquid outlet and the liquid inlet, so as to seal the gap between the joint of the liquid outlet and the liquid inlet, and the liquid matrix cannot leak out in the unsealing process of the first sealing piece.

Second embodiment, fig. 11-12 show a perspective view and an exploded view of a perspective view of an atomizer 200 according to a further embodiment of the present invention, in which the atomizer 200 includes a reservoir 10a, an atomizing element 20a and a bottom cover 30a, the reservoir 10a includes an air outlet 11a, a reservoir cavity 12a and an air duct 13a, which are the same as those in the first embodiment, one end of the reservoir 10a opposite to the air outlet 111a of the reservoir is open, and the atomizing element 20a can be installed in the reservoir 10a through the open end of the reservoir 10 a.

The bottom cover 30a is provided with a first buckling position 31a and a second buckling position 32a, the reservoir 10a is provided with a buckling piece 14a matched with the first buckling position 31a and the second buckling position 32a, when the buckling piece 14a is buckled with the first buckling position 31a, the bottom cover 30a and the reservoir 10a are mutually assembled at the first assembling position, and at the moment, a gap 50a is still kept between the bottom cover 30a and the reservoir 10a and is not completely and tightly combined, as shown in fig. 13; when the bottom cap 30a is further pushed to snap-fit the latch 14a to the second latch site 32a, the bottom cap 30a and the reservoir 10a are assembled to each other at the second assembly position, and the bottom cap 60 is tightly combined with the reservoir 40, as shown in fig. 14. As described in the first embodiment, the positions of the first fastening position 31a, the second fastening position 32a and the adaptive fastener 14a can be interchanged, and other fixing connection methods known to those skilled in the art can be used as well. In this embodiment, the atomizing assembly 20a and the reservoir 10a are connected in the first assembly position and the second assembly position.

Referring to fig. 13, the atomizing assembly 20a includes a support 23a, a third sealing element 24a, an atomizing core 25a and a base 26a, and the support 23a, the third sealing element 24a, the atomizing core 25a and the base 26a in the second embodiment are the same as the support 23, the third sealing element 24, the atomizing core 25 and the base 26 in the first embodiment except that the second liquid guiding hole 231a of the support 23a is not provided with the pressing member 233 any more, and the description thereof is omitted.

To seal the reservoir 12a, the atomizing assembly 20a further includes a flexible sealing member 22a, the flexible sealing member 22a being disposed between the reservoir 12a and the support 23a and having a profile that is adapted to the cross-section of the interior profile of the reservoir 10a to seal the reservoir 12a from liquid leakage from the reservoir 12 a. Specifically, in the present embodiment, the flexible sealing element 22a is sleeved on the top of the support 23a, so that the support 23a provides a rigid support for the flexible sealing element, and at this time, the flexible sealing element 23a blocks the conduction path between the second liquid guiding hole 231a of the support 23a and the reservoir 12a, so that the liquid in the reservoir 12a cannot flow to the atomizing assembly 20 a. In the first assembled position, the flexible sealing element 22a seals the reservoir; in the second assembled position, the flexible sealing member 22a is broken and liquid in the reservoir 12a is allowed to flow toward the atomizing assembly 20a for atomization. In order to enable the atomization assembly 20a to flow to the air outlet hole 11a of the reservoir after generating aerosol, the flexible sealing element 22a is further opened with a vent hole 221a, and the air duct 13a is communicated with the vent hole 221 a.

Further, referring to fig. 15, in order to break the flexible sealing element 22a at the second assembly position, a weak area 222a capable of being easily broken by being pressed is formed on the flexible sealing element 22a, and the weak area 222a is defined by a groove formed on the flexible sealing element 22a, and the groove can be set to various shapes, which can be set by those skilled in the art according to specific scenarios, and the shape of the groove is preferably set to a ring shape in this embodiment. The weakened area 222a has a very thin thickness compared to the rest of the flexible sealing element 22a, which thickness facilitates its rupture, for example a thickness of about 0.1 mm. In the second assembled position, the weakened region 222a can be broken to connect the second fluid aperture 231a of the support 23a with the fluid flow path of the reservoir 12a, such that fluid in the reservoir 12a can flow through the second fluid aperture 231a of the support 23a to the atomizing core 25a of the atomizing assembly 20 a.

Further, with continued reference to fig. 16 and with reference to fig. 14, in order to cooperate with the flexible sealing element 22a to be ruptured when in the second assembled position, a pressing member 15a extending along the length of the reservoir 12 is cooperatively disposed in the reservoir 10a, the pressing member 15a extending within the reservoir 12a for releasing the sealing of the reservoir 12a by the sealing element 22a, and may be in the form of a sheet or a rod having a free end facing the open end of the reservoir 10a and configured to press against the pressing end 151a of the sealing element. In order to provide the squeezing member 15a with sufficient strength so that the squeezing end 151a can squeeze the flexible sealing element 22 to rupture it, the squeezing member 15a is at least partially connected to the airway tube 13a of the reservoir 10 a.

As described in conjunction with the above structure, in the production process, the bottom cap 30a with the atomizing assembly 20a assembled thereon may be pressed in from the open end of the reservoir 10a until the first snap-fit position 31a on the bottom cap 30a is snapped into the snap-fit member 14a of the reservoir 10a, and at this time, the bottom cap 30a and the reservoir 10a are not completely tightly combined with each other with a certain distance 50a therebetween; meanwhile, the weakened area 222a of the flexible sealing element 22a abuts against the pressing end 151a, but the weakened area 222a is not yet broken, and the liquid storage chamber 12a and the second liquid guiding hole 231a of the bracket 23a are still in an isolated or sealed state, which is the pre-assembly state of the above-mentioned embodiment.

When the user needs to use the device, the user can further press the bottom cap 30a further toward the open end of the reservoir 10a, and the bottom cap 30a will drive the atomizing assembly 20a further toward the inside of the reservoir 10a until the second latching position 32a on the bottom cap 30a is engaged with the latch 14a of the reservoir 10 a. In the process, the weak region 222a of the sealing element 22a is further pressed by the pressing end 151a, so that the weak region 222a is broken by the pressing of the pressing end 151a, and thus the liquid storage chamber 12a is communicated with the second liquid guide hole 231a of the bracket 23a, and the liquid medium can flow from the liquid storage chamber 12a to the atomizing assembly 20a for atomization.

It can be understood that, since the sealing member 22a in the present embodiment is made of a flexible material, for example, the sealing member 22a in the present embodiment may be made of a silicone material, the pressing end 151a may preferably be configured to be in a sharp-pointed shape, when the sealing member 22a is further moved from the first assembly position to the second assembly position along with the bottom cover 30a, the pressing end 151a having the sharp-pointed shape may puncture the weak area 222a of the flexible sealing member 22a at a certain point, and since the flexible sealing member 22a has a certain elastic force, the weak area 222a may be rapidly shrunk around the puncture point under the elastic force, so as to expand the fracture range, in such a manner that the weak area 222a may not fall into the atomizing assembly 20 due to fracture under the pressing of the pressing end 151a to form a fixed residue.

In some embodiments, the sealing element 22a may also be made of a hard glue material, and the weak region 222a is also made of a hard glue material, when the sealing element 22a is further moved from the first assembly position to the second assembly position along with the bottom cover 30a, the pressing end 151a presses the weak region 222a, and since the weak region 222a is made of a hard glue material, at least a portion of the weak region 222a is broken under the pressing force of the pressing end 151a, so that the liquid storage chamber 12a and the second liquid guide hole 231a of the bracket 23a can be conducted.

The utility model also provides an electronic atomization device, which comprises the atomizer and the power supply mechanism (not shown), wherein the atomizer and the power supply mechanism are detachably or fixedly connected, the power supply mechanism comprises a battery cell (not shown), a control board (not shown) and a fixed seat (not shown), the control board is fixed on the fixed seat, the fixed seat is provided with a first elastic sheet (not shown) and a second elastic sheet (not shown), and the first elastic sheet and the second elastic sheet are electrically connected with the control board and are electrically connected with the battery cell through the control board.
