Air pressure changes. For example, when there are two air guiding grooves 142 , the two air guiding grooves 142 are symmetrically arranged along the air inlet hole 140 , and the equal diameter ratio of the width of the air guiding groove 142 to the air inlet hole 140 is 1.0.

Specifically, the fixing portion 171 may be connected to the inner surface of the housing 50 or the bracket 10 by clamping, screwing or bonding. For example, the fixing part 171 is a protrusion, and the housing 50 or the bracket 10 has a groove, and the protrusion cooperates with the groove to realize the connection. For another example, the fixing portion 171 has external threads. The inner surface of the housing 50 or the bracket 10 has internal threads, and the external threads cooperate with the internal threads to realize the connection. For example, an adhesive layer is disposed on the fixing portion 171 to be fixedly bonded to the inner surface of the housing 50 or the bracket 10 .

One of the shielding portion 172 and the intake column 14 has a first engaging portion, and the other has a second engaging portion.

Wherein, one of the first engaging portion and the second engaging portion may be a buckle, and the other may be a groove. For example, the surface of the shielding portion 172 facing the air inlet 140 has a protrusion corresponding to the air guide groove 142 , and the height of the protrusion is lower than the depth of the air guide groove 142 . The protrusion is engaged in the air guiding groove 142 and spaced from the bottom wall of the air guiding groove 142 to form the air inlet 141 .

Alternatively, there is a protrusion on the blocking portion 172 , and the protrusion is arranged in the air inlet 140 and has an interference fit with the side wall of the air inlet 140 to achieve fixation. In this solution, the air inlet 141 is a through hole forming the side wall of the air inlet column 14 of the air inlet 140 .

In this embodiment, the side of the bracket 10 has an annular groove 102, the fixing part 171 is annular and embedded in the annular groove 102, the side wall of the liquid storage tank 13 has a gap 131 at the position where the air inlet column 14 is embedded, The shielding portion 172 extends from the annular fixing portion 171 to the port of the air inlet 140 facing the atomizer 200 through the gap 131 . Wherein, the ring-shaped fixing portion 171 can also be interference-filled between the housing 50 and the bracket 10 to serve as a sealing ring.

In some optional embodiments, the material of the shielding member 17 can be rubber, silicone or plastic. The shield 17 may also be connected to the inner surface of the housing 50 or the bracket 10 , for example, integrally injection molded with the housing 50 .

When in the liquid tank 13 , it will directly pass through the air inlet column 14 , so that the air inlet 141 can detect the airflow condition more directly and efficiently.

For example, when the side wall of the liquid storage tank 13 is provided with a vent 18, the vent 18 is set at the position where the side wall of the liquid storage tank 13 is embedded with the air inlet column 14, or is symmetrically arranged with the notch 131 in the liquid storage tank. 13 sides.

The symmetrical arrangement may also be arranged at other positions on the side wall of the liquid storage tank 13, which is not limited here.

Specifically, when the atomizer 200 is subjected to suction operation, outside air enters the electronic atomization device 300 through the vent 18 , and then flows into the atomizer 200 through the liquid storage tank 13 . Therefore, by setting the vent 18 at the position where the air inlet column 14 is embedded on the side wall of the liquid storage tank 13, the outside air first passes through the air inlet 141, and then flows into the liquid storage tank 13 and the atomizer 200, compared to the Other positions on the side wall of the liquid storage tank 13 are provided with air vents 18, which can prevent the outside air from passing through the liquid storage tank 13 first, carrying more water vapor, and then flow through the air inlet 141 to block the air inlet 141, thereby causing The airflow sensor 20 cannot detect the airflow change, and the electronic atomization device 300 cannot be started normally.
