It should be noted that the seal 60 uncovers the inlet 230, and it is understood that the seal 60 unblocks the inlet 230 from the atmosphere.
In this embodiment, in the second state, the air inlet 230 is connected to the atmosphere via the atomizing chamber 25.
As shown in fig. 6, the line with an arrow in fig. 6 indicates a flow path of the air flow to supply the liquid storage chamber 12 through the ventilation channel 23.

When the atomizer 100 works, the atomizing core 30 continuously consumes the liquid stored in the liquid storage cavity 12, and then the air pressure in the liquid storage cavity 12 is reduced due to the reduction of the liquid, and the too low air pressure in the liquid storage cavity 12 causes the liquid discharge difficulty of the atomizing core 30, so that the liquid supply to the atomizing core 30 is insufficient, the atomizing core 30 is easily burnt to generate scorched smell, and the like, which detracts from the service life and quality of the atomizer 100.
By arranging the air exchange channel 23, when the air pressure in the liquid storage cavity 12 is too low, air can be supplied into the liquid storage cavity 12 through the air exchange channel 23, so that the air pressure balance in the liquid storage cavity 12 is maintained, and the condition that the liquid supply to the atomizing core 30 is insufficient due to too low air pressure in the liquid storage cavity 12 is avoided; a sealing element 60 is further arranged to cover the air inlet 230 of the ventilation channel 23, so that when air supply in the liquid storage cavity 12 is not needed, the air inlet 230 can be covered to isolate the liquid storage cavity 12, and the smoke liquid in the liquid storage cavity 12 is prevented from leaking from the ventilation channel 23; when the air pressure in the reservoir chamber 12 is unbalanced, the sealing member 60 is released from the air inlet 230 to communicate the atmosphere with the air inlet 230, and the air is supplied into the reservoir chamber 12 through the ventilation passage 23.
The first state of the atomizer 100 is a state in which the air pressure in the liquid storage chamber 12 is not unbalanced, i.e., the liquid storage chamber 12 does not need to be supplied with air and the liquid discharge is smooth; the second state of the atomizer 100 is a state in which the air pressure in the liquid storage chamber 12 is unbalanced, and liquid feeding in the liquid storage chamber 12 is not smooth, resulting in insufficient liquid supply to the atomizing core 30.
Specifically, the sealing member 60 covers the air inlet 230, so that the air exchange channel 23 is isolated from the atmosphere, and when a user sucks the atomizer 100, the smoke liquid in the liquid storage cavity 12 is continuously reduced, the air pressure in the liquid storage cavity 12 is continuously reduced, and the hydraulic pressure in the air exchange channel 23 is also continuously reduced, that is, the acting force applied to the sealing member 60 by the smoke liquid through the air exchange channel 23 is gradually reduced, so that the pressure difference between the inner side and the outer side of the sealing member at the air inlet 230 is larger, and after reaching a certain degree, a gap is formed between the atomizing base 20 and the sealing member 60 under the pushing of the external atmosphere, and the gap is communicated with the air inlet 230, that is, the air inlet 230 is communicated with the atmosphere through the gap, so that the air is supplied into the liquid storage cavity 12 through the air inlet 230 and the air outlet 232 in sequence, and the unsmooth liquid discharge caused by the unbalanced air pressure in the liquid storage cavity 12 is relieved.
