In one embodiment, as shown in fig. 3 and 4, the path of ventilation channel 20 may be straight or may be tortuous. In one embodiment, the ventilation channel 20 is configured to be tortuous and is lower at one end of the sinking platform 322 near the reservoir 10 than at one end of the sidewall body 321 near the reservoir 10. Specifically, a certain gap 325 is left at the top of the sinking platform 322, and is used for communicating with the ventilation groove 33 and the ventilation port 441, respectively, so as to form the ventilation channel 20. That is, the ventilation groove 33 communicates with the ventilation port 441 through the gap 325 near the second end 202 of the first seal member 40, and the ventilation passage 20 is bent in a direction in which the land 322 approaches the first seal member 40, that is, the ventilation passage 20 is axially disposed at a portion of the ventilation groove 33 and bent toward a horizontal direction at a portion of the land 322 adjacent the first seal member 40, so that the ventilation groove 33 communicates with the ventilation port 441. In this embodiment, the height of the sinking platform 322 is less than the height of the sidewall body 321 by 0.2-0.3 mm, so that the liquid storage bin 10 is not easy to leak liquid, and can play a role of ventilation. In other embodiments, the ventilation opening 441 can be disposed on the same line with the ventilation slot 33, and directly communicates with the ventilation opening 441 from the end of the ventilation slot 33 close to the ventilation opening 441, so as to form a straight ventilation channel 20.

For example, the sidewall body 321 includes two opposite long sides and two opposite short sides, the two sinking platforms 322 are respectively disposed on the two opposite short sides, and the two first supporting portions 323 are respectively disposed on the two opposite long sides. The inner cavity of the base 30 is provided with a second supporting portion 324, the bottom end of the second supporting portion 324 is fixed on the surface of the base body 31 close to the first sealing element 40, the top end extends towards one side close to the first sealing element 40, and the first supporting portion 323 and the second supporting portion 324 are correspondingly connected with the groove or the clamping groove inside the first sealing element 40.

A fourth groove 434 recessed inward is formed between the first sealing member body 41 and the first protrusion 42, and the first supporting part 323 is connected to the fourth groove 434 of the first sealing member 40 to seal the joint of the base 30 and the first sealing member 40, thereby achieving tight connection with the first sealing member 40. The number, size and shape of the first supporting portion 323 and the second supporting portion 324 may be set as required as long as the matching connection with the third groove 433 and the fourth groove 434 is achieved. The heights of the first supporting portion 323 and the second supporting portion 324 may be uniform or non-uniform, and the present application is not limited thereto.

As shown in fig. 2 to 4, the base body 31 has a liquid accumulation chamber 34 near the inner surface of the liquid storage chamber 10, and the first end 201 of the ventilation channel 20 extends to the bottom of the liquid accumulation chamber 34 and is communicated with the liquid accumulation chamber 34, so that the pressure of the liquid storage chamber 10 is reduced, and the condensate and the leaked atomized liquid can flow back to the liquid storage chamber 10 along the ventilation channel 20, thereby avoiding leakage. The bottom of the inner cavity of the base 30 is provided with a first holding portion 35 and an air inlet 36, and the air inlet 36 is used for air inlet. In one aspect, gas entering through the gas inlet 36 may enter the aerosolizing chamber 61, carry aerosol, and then enter the aerosol passage 90. On the other hand, the gas introduced from the gas inlet 36 may be introduced into the ventilation passage 20 through the communication chamber 361 and the liquid accumulation chamber 34 in this order to be ventilated. The periphery of the air inlet 36 is provided with a second holding part 37 protruding from the air inlet 36, and the first holding part 35 and the second holding part 37 are used for locking the condensate in the liquid collecting bin 34 and the atomized liquid leaked from the liquid storage bin 10. The inlet 36 is provided with a check valve 48, the check valve 48 may cover the inlet 36, the check valve 48 may be opened when gas enters from the inlet 36, and the check valve 48 may be closed when gas does not enter. Meanwhile, the gas in the atomizing chamber 61 and the liquid in the liquid loading chamber 34 cannot flow out from the gas inlet 36. Therefore, the check valve 48 prevents the liquid in the sump 34 from flowing out while ensuring the intake of the air intake 36.
