The porous body 81 is at least partially accommodated in the second accommodating chamber 43. 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 through an interference fit. At this time, the liquid-absorbing surface 811 of the porous body 81 is accommodated in the second accommodating chamber 43 and faces the liquid-conducting hole 411 of the first sealing member 40, so that the liquid matrix can flow to the suction through the liquid-conducting hole 411.

A first insertion part 521 extends axially from the lower surface 52 toward the liquid storage part 20 , and a rib 5211 is arranged around the outer wall of the first insertion part 521 , and the first insertion part 521 passes through the opening end of the liquid storage chamber 251 2211 is inserted into the liquid storage chamber 221, and the cross-sectional shape of the first insertion part 521 is adapted to the opening shape of the opening end 2211 of the liquid storage chamber 221, so the first insertion part 521 can be fitted with the The end wall of the opening end 2211 is closely fitted, thereby blocking the opening end 2211 of the liquid storage chamber 221 and preventing the liquid matrix from flowing out from the opening end 2211 of the liquid storage chamber 221 when the atomizer 100 is inverted. At the same time, in order to prevent the first sealing member 40 from falling into the liquid storage chamber 221 due to the bumping of the electronic atomization device 100 during transportation, the cross-sectional area of the first insertion part 521 is smaller than the area of the lower surface 52, so that the lower surface A part of the surface 52 abuts against the end surface of the opening 2211 of the liquid storage chamber 221 , preventing the first sealing member 40 from falling into the liquid storage chamber 221 .

Please continue to refer to FIG. 12 , which shows a schematic cross-sectional view of the first casing 10 in one direction. One end of the first casing 10 is provided with an air outlet 12 , through which the aerosol generated by atomization can escape the atomizer 100 , and the user can inhale the aerosol through the air outlet 12 . The other end opposite to the air outlet 12 is configured as an open end 13, and the proximal end 211 of the liquid storage part 20 extends into the first housing 10 through the opening 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 airflow channel 2221 and the second airflow channel 2222 , and enter the first casing 10 through the opening of the proximal end 211 The inside is then discharged through the air outlet 12 of the first casing 10 .

The interior of the first housing 10 is provided with a clamping portion 14 that 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, and the clamping portion 14 faces the side of the first housing 10. A second insertion portion 141 extends axially in the direction of the opening end 13, and a second through hole 53 axially penetrating through the body of the second sealing member 50 is provided on the second sealing member 50. When the first housing 10 and the liquid storage When the parts 20 are engaged and connected, the clamping part 14 is clamped in the clamping space 512 , and at the same time, the second inserting part 141 is inserted into the second through hole 53 . It is easy to understand that the cross-sectional shape of the second insertion portion 141 is adapted to the shape of the second through hole 53 , so that the second insertion portion 141 and the second through hole 53 achieve an interference fit, and the second insertion portion 141 and the second through hole 53 achieve an interference fit. The hole walls of the second through hole 53 are in close contact with each other in the circumferential direction, thereby sealing the second through hole 53 and preventing the liquid matrix in the liquid storage chamber 221 from leaking through the second through hole 53 when the electronic atomization device 100 is turned upside down.

It should be noted that in this embodiment, the second through hole 53 is provided on the second sealing member 50 to allow part of the air in the liquid storage chamber 221 to pass through the second through hole when the second sealing member 50 is inserted into the liquid storage chamber 221 . out of hole 53. Specifically, during actual production and assembly, the liquid matrix is pre-loaded into the liquid storage chamber 221, and then the second sealing member 50 is installed at the opening end 2211 of the liquid storage chamber 221. At this time, with the second sealing member 50 The air in the liquid storage chamber 221 is compressed, and part of the air is discharged from the second through hole 53, and then the first housing 10 is assembled on the liquid storage part 20, while the second socket part 141 of the first housing 10 Inserted into the second through hole 53, although the air in the liquid storage chamber 251 will also be compressed with the insertion of the second plug-in part 141 at this time, part of the air has been discharged from the second through hole 53, thereby causing the storage There is only a small amount of air in the liquid chamber 221 to compress the liquid matrix, and the liquid matrix will not flow to the atomizing element 80 too much to cause leakage under the action of a small amount of air pressure. And if the second through hole 53 is not provided on 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 It is compressed and cannot be discharged, and the compressed air will squeeze the liquid matrix, and the liquid matrix will flow to the atomizing element 80 too much under the action of a relatively large gas pressure, thereby easily causing leakage.

Further, in order to avoid that when the second insertion part 141 is inserted into the second through hole 53 , the second sealing member 50 may sag under the extrusion force of the second insertion part 141 , thus causing the second sealing member 50 to sag. A gap is formed between the liquid storage cavity 221 and the inner wall, thereby affecting the sealing performance of the second sealing member 50 . The second sealing member 50 is provided with the above-mentioned protrusion 511 , and when the first housing 10 is engaged with the liquid storage portion 20 , the clamping portion 14 of the first housing 10 is located in the clamping space 512 of the second sealing member 50 , the protrusion 511 clamps the clamping portion 14 to reduce the extrusion force exerted by the second insertion portion 141 on the second sealing member 50 , thereby effectively preventing the second sealing member 50 from sinking under the extrusion force.

It is worth noting that, in some embodiments, both the first airflow channel 2221 and the second airflow channel 2222 have a first air outlet port 22211 and a second air outlet port 22221 escaping from the liquid storage part 20 , as shown in FIG. 5 . The heights of the first gas outlet port 22211 and the second gas outlet port 22221 are both lower than the height of the liquid injection opening 2211, so that the volume of the liquid storage chamber 221 can be increased, thereby increasing the liquid volume of the liquid matrix that can be stored.
