Further, a partition wall 2212 radially extends inside the cavity structure 22, the partition wall 2212 divides the inside of the cavity structure 22 into the liquid storage cavity 221 and the first accommodating cavity 223, the first accommodating cavity 223 accommodates the atomizing element 80 of the electronic atomizing device 100 therein, and the atomizing element 80 is in fluid communication with the liquid storage cavity 221, so that the liquid matrix in the liquid storage cavity 221 can flow to the atomizing element 80 in the first accommodating cavity 223 for atomization. Specifically, the partition wall 2212 is provided with a liquid guiding opening 2213, the liquid matrix in the liquid storage cavity 221 can flow to the atomizing element 80 through the liquid guiding opening 2213, and the liquid storage cavity 221 and the first accommodating cavity 223 are distributed on two sides of the liquid guiding opening 2213.

In some embodiments, when the cavity structure 22 extends axially inside the housing 21, the cavity structure 22 divides the interior of the housing 21 into the reservoir cavity 221, the first chamber 2221 and the second chamber 2222 which are isolated from each other, the first chamber 2221 and the second chamber 2222 are distributed on two sides of the reservoir cavity 221, and the aerosol can respectively flow through the first chamber 2221 and the second chamber 2222, that is, the air flow passages are divided into the first air flow passage 2221 and the second air flow passage 2222, and preferably, the first air flow passage 2221 and the second air flow passage 2222 have substantially the same size in the same cross section, so as to more smoothly escape from the reservoir 20.

Specifically, an opposite sidewall 222 of the cavity 22 is connected between opposite inner walls of the reservoir 20, and the other sidewalls of the cavity 22 are directly formed by the inner walls of the reservoir 20, so that the interior of the housing 21 is divided into the reservoir 221, the first chamber 2221 and the second chamber 2222 by the sidewalls 222. It should be noted that in other embodiments of the present invention, the outer wall of the chamber structure 22 may be circumferentially spaced from the inner wall of the housing 21, and the gap may be used to form the air flow passage.

The electronic vaping device 100 also includes a first seal 40 for sealing the reservoir chamber 221. With continued reference to fig. 7 and 8, fig. 7 and 8 respectively show perspective views of the first sealing member 40 in two directions. The first sealing member 40 is made of a flexible soft rubber material, such as silicone rubber or rubber. The first sealing member 40 includes an end surface 41 and a side wall 42 extending from the end surface 41 toward a direction away from the liquid storage cavity 221, the end surface 41 and the side wall 42 define a second accommodating chamber 43, and the second accommodating chamber 43 is used for holding the atomizing element 80 of the electronic atomizing device. The end surface 41 is provided with a liquid guiding hole 411, the first sealing element 40 is assembled in the first accommodating chamber 223 in an interference manner, so that the first sealing element 40 is elastically abutted against the inner wall of the first accommodating chamber 223, meanwhile, the liquid guiding hole 411 of the first sealing element 40 is communicated with the liquid guiding opening 2213, the liquid matrix in the liquid storage cavity 221 cannot leak through an assembly gap between the atomizing element 80 and the inner wall of the second accommodating chamber 223, the first sealing element 40 provides sealing between the atomizing element 80 and the inner wall of the first accommodating chamber 223, and the liquid matrix can only flow to the atomizing element 80 in the second accommodating chamber 43 through the liquid guiding opening 2213 and the liquid guiding hole 411.

With continued reference to fig. 9, the atomizing element 80 includes a porous body 81 and a heating element 82 coupled to the porous body 81, the porous body 81 may be made of a hard capillary structure such as porous ceramic, porous glass, etc., the porous body 81 may be, but is not limited to, a block structure in the embodiment, and according to the use situation, it includes a liquid absorbing surface 811 and an atomizing surface 812 oppositely disposed along the axial direction of the electronic atomizing device 100, i.e., the upper and lower surfaces of the block porous body 81 in fig. 8, the liquid absorbing surface 811 is used for absorbing the liquid matrix, and the heating element 82 is coupled to the atomizing surface 812 for heating and atomizing the liquid matrix. The porous body 81 is at least partially accommodated in the second accommodating chamber 43, and since the first sealing member 40 is made of a flexible material, the porous body 80 can be tightly fitted in the second accommodating chamber 43 by interference fit, and the liquid absorbing surface 811 of the porous body 81 is accommodated in the second accommodating chamber 43 and faces the liquid guiding hole 411 of the first sealing member 40, so that the liquid matrix can flow to the liquid absorbing surface 811 through the liquid guiding hole 411 and to the atomizing surface 812 through the inner microporous structure of the porous body 81.

The heating element 82 is preferably formed on the atomization surface 812 by mixing conductive raw material powder and a printing aid into paste and then sintering the paste after printing according to a suitable pattern, so that all or most of the surface of the heating element is tightly combined with the atomization surface 812, and the heating element has the effects of high atomization efficiency, low heat loss, dry burning prevention or great reduction of dry burning and the like. In some embodiments, the heating element 82 may take various configurations, and the heating element 82 may be a sheet-shaped heating element combined on the atomizing surface 812 and formed with a specific pattern, or a heating net, a disk-shaped heating element formed by a spiral heating wire, a heating film, or other forms; for example, the particular pattern may be a serpentine shape. The heating element 82 may be made of stainless steel, nichrome, ferrochromium alloy, titanium metal, or the like in some embodiments. Therefore, when the liquid substrate flows onto the atomization surface 812, the heating element 82 of the atomization surface 812 can heat and atomize the liquid substrate, and release the aerosol generated after atomization from the atomization surface 812.

Further, the cavity structure 22 is further provided with an injection opening 2211 for injecting liquid, and before the first housing 10 is not connected to the reservoir 30, the liquid matrix may be injected into the reservoir 221 through the injection opening 2211 in advance. After the liquid medium is filled, the first housing 10 is fixedly connected to the liquid reservoir 30.

Further, in order to prevent the liquid matrix from leaking from the liquid injection opening end 2212 when the electronic atomization device 100 is inverted, the electronic atomization device 100 further includes a second sealing member 50, fig. 10 and 11 respectively show a perspective view of the second sealing member 50 in two directions, and the second sealing member 50 is also made of a flexible soft rubber material such as silicon gel or rubber. The second sealing member 50 has an upper surface 51 and a lower surface 52 opposite to each other, and a sidewall extending between the upper surface 51 and the lower surface 52, and a plurality of protrusions 511 axially extend from the upper surface 51 toward the first housing 10, and the plurality of protrusions 511 form a clamping space 512. The first inserting-connecting part 521 axially extends from the lower surface 52 to the reservoir part 20, a convex rib 5211 is arranged around the outer wall of the first inserting-connecting part 521, the first inserting-connecting part 521 is inserted into the reservoir cavity 221 through the open end 2211 of the reservoir cavity 251, and meanwhile, the cross section of the first inserting-connecting part 521 is matched with the opening shape of the open end 2211 of the reservoir cavity 221, so that the first inserting-connecting part 521 can be tightly attached to the end wall of the open end 2211 in an interference fit mode, the open end 2211 of the reservoir cavity 221 is blocked, and liquid matrix is prevented from flowing out of the open end 2211 of the reservoir cavity 221 when the atomizer 100 is inverted. Meanwhile, in order to prevent the first sealing member 40 from falling into the reservoir 221 due to bumping of the electronic atomization device 100 during transportation, the cross-sectional area of the first insertion portion 521 is smaller than that of the lower surface 52, so that a part of the lower surface 52 abuts against the end surface of the open end 2211 of the reservoir 221, and the first sealing member 40 is prevented from falling into the reservoir 221.

Continuing to refer to fig. 12, fig. 12 shows a schematic cross-sectional view of the first housing 10 in one direction. The first housing 10 has an air outlet 12 at one end thereof, and aerosol generated by atomization can escape from the atomizer 100 through the air outlet 12, and a user can inhale the aerosol through the air outlet 12. And the other end opposite to the air outlet hole 12 is configured as an open end 13, the proximal end 211 of the liquid storage part 20 extends into the first housing 10 through the open end 13, and the first housing 10 is hollow, so that the aerosol generated by the atomizing element 80 can flow to the proximal end 211 of the liquid storage part 20 through the first air flow channel 2221 and the second air flow channel 2222, and enter the inside of the first housing 10 through the opening of the proximal end 211, and then be discharged from the air outlet hole 12 of the first housing 10.

The first housing 10 is provided with a clamping portion 14 which can be partially clamped in the clamping space 512, the clamping portion 14 is formed by extending the inner wall of the first housing 10, the clamping portion 14 is provided with a second insertion portion 141 axially extending towards the opening end 13 of the first housing 10, the second sealing member 50 is provided with a second through hole 53 axially penetrating through the body of the second sealing member 50, when the first housing 10 is clamped with the liquid storage portion 20, the clamping portion 14 is clamped in the clamping space 512, and the second insertion portion 141 is inserted into the second through hole 53. It is easy to understand that the cross-sectional shape of the second inserting portion 141 is matched with the shape of the second through hole 53, so that the second inserting portion 141 and the second through hole 53 are in interference fit, the second inserting portion 141 and the hole wall of the second through hole 53 are tightly attached to each other in the circumferential direction, and the second through hole 53 is further sealed, so that the liquid matrix in the liquid storage cavity 221 is prevented from leaking through the second through hole 53 when the electronic atomization device 100 is inverted.

It should be noted that the second through hole 53 is provided in the second sealing member 50 in this embodiment to discharge a part of air of the reservoir 221 from the second through hole 53 when the second sealing member 50 is inserted into the reservoir 221. Specifically, during actual production and assembly, the liquid matrix is loaded into the reservoir 221 in advance, the second sealing member 50 is mounted at the opening end 2211 of the reservoir 221, at this time, the air in the reservoir 221 is compressed along with the insertion of the second sealing member 50, a part of the air is discharged from the second through hole 53, the first housing 10 is assembled on the reservoir 20, and the second socket 141 of the first housing 10 is inserted into the second through hole 53, at this time, although the air in the reservoir 251 is also compressed along with the insertion of the second socket 141, a part of the air is already discharged from the second through hole 53, and thus only a small amount of air in the reservoir 221 compresses the liquid matrix, and the liquid matrix does not excessively flow onto the atomizing element 80 to cause leakage under the action of the small amount of air pressure. If the second through hole 53 is not formed in the second sealing member 50, the second sealing member 50 is a completely closed sealing member, and as the second sealing member 50 is inserted into the liquid storage chamber 221, the air in the liquid storage chamber 221 is compressed and cannot be discharged, the compressed air presses the liquid substrate, and the liquid substrate is excessively flowed onto the atomizing element 80 by the large gas pressure, so that leakage is easily generated.

Further, in order to prevent the second insertion part 141 from being inserted into the second through hole 53, the second sealing member 50 may be depressed by the pressing force of the second insertion part 141, so that a gap is generated between the second sealing member 50 and the inner wall of the reservoir chamber 221, and the sealing performance of the second sealing member 50 is affected. The second sealing element 50 is provided with the protrusion 511, when the first housing 10 is connected with the liquid storage part 20 in a clamping manner, the clamping part 14 of the first housing 10 is located in the clamping space 512 of the second sealing element 50, the protrusion 511 clamps the clamping part 14, the extrusion force applied to the second sealing element 50 by the second insertion part 141 is reduced, and further the second sealing element 50 is effectively prevented from sinking under the action of the extrusion force.

It is worth noting that in some embodiments, the first air flow channel 2221 and the second air flow channel 2222 are provided with a first air outlet port 22211 and a second air outlet port 22221 which escape from the liquid storage part 20, as shown in fig. 5. The first outlet port 22211 and the second outlet port 22221 are each lower in height than the liquid injection open end 2211 so that the volume of the reservoir chamber 221 can be increased to increase the amount of liquid medium that can be stored.

Further, the electronic atomization device 100 further includes a ventilation channel for communicating the external air with the liquid storage cavity 221, so as to guide the external air into the liquid storage cavity 221, and prevent the liquid storage cavity 221 from generating negative pressure along with consumption of the liquid substrate, and further prevent the liquid substrate from flowing onto the atomization element 80 smoothly under the action of the negative pressure, thereby causing the atomization element 80 to be easily dried. The ventilation channel has an air inlet through which outside air enters the ventilation channel and an air outlet from which outside air escapes in the form of bubbles. The first sealing member 40 extends to the liquid storage cavity 221 to form a bubble guiding portion 412, the bubble guiding portion 412 is disposed opposite to the air outlet of the air exchange channel, and the bubble guiding portion 412 is used for guiding the bubbles escaping from the air outlet of the air exchange channel during air exchange of the electronic atomization device 100 to the liquid storage cavity 221, that is, guiding the bubbles to the direction away from the liquid absorption surface 811 of the atomization element 80, so as to prevent the bubbles from accumulating on the liquid absorption surface 811 after escaping from the air outlet of the air exchange channel, thereby possibly blocking the liquid guide opening 2213, and further preventing the liquid matrix in the liquid storage cavity 221 from smoothly flowing onto the atomization element 80, thereby causing dry burning of the atomization element 80.

In some embodiments, as shown in FIG. 13, FIG. 13 shows a schematic cross-sectional view of the reservoir 20 in one direction.
