In this embodiment, the battery cell 30 and the control board 40 are also mounted on the back plate 11; the housing 50 is provided with an air suction hole 51, and the external air flows through the reservoir 13 through the air suction hole 51 and flows to the nebulizer 200, so that whether the user sucks the nebulizer 200 can be detected through the air inlet hole 140.

Two sides of the liquid storage tank 13 are respectively provided with a containing groove 130, the containing groove 130 is used for installing electrodes, and the containing groove 130 can also be used for installing magnetic attraction pieces. For example, the magnetic member is disposed in the receiving groove 130 and surrounds the electrode. The magnetic member may be a permanent magnet or a ferromagnetic member, and the magnetic member is magnetically connected to the atomizer 200, and the electrode is electrically connected to the atomizer 200.

In other embodiments, the bracket 10 may also only include the connection seat 12, and the airflow sensing part 20, the battery cell 30, the control board 40, and the like may also be disposed on other structural members; alternatively, the stent 10 may have other shapes, such as a substantially prismatic or cylindrical stent 10, and the like, which is not particularly limited in this application.

In this embodiment, the air inlet hole 140 is disposed at an end of the air inlet column 14 away from the bottom wall of the liquid storage tank 13, so as to increase the height of the port of the air inlet hole 140 and prevent the accumulated liquid in the liquid storage tank 13 from flowing into the air inlet hole 140 too much.

Alternatively, the air inlet column 14 may be disposed in the liquid storage tank 13, that is, the air inlet column 14 is connected to the bottom wall of the liquid storage tank 13, and the air inlet column 14 is disposed at a distance from the side wall of the liquid storage tank 13; alternatively, the air inlet pillar 14 may be partially or fully embedded in the sidewall of the reservoir 13, thereby allowing a greater distance from the air inlet of the atomizer 200, which may significantly reduce the risk of leakage into the air vent 140.

The air inlet (not shown) on the atomizer 200 faces the liquid storage tank 13, and the liquid storage tank 13 is mainly used for containing leakage liquid leaked from the air inlet on the atomizer 200, so as to prevent the leakage liquid from flowing to the battery cell 30 and the control board 40.

In this embodiment, the partition wall 15 and the air inlet column 14 are both disposed on the bottom wall of the reservoir 13, the air inlet column 14 is partially or completely embedded in the side wall of the reservoir 13, the partition wall 15 is disposed around the air inlet column 14, the partition groove 16 is formed between the partition wall 15 and the air inlet column 14, an opening 150 is formed on the partition wall 15, and the partition groove 16 is communicated with the reservoir 13 through the opening 150.

Through setting up the division wall 15, can further increase the degree of difficulty that the liquid on the terminal surface of support 10 flowed to inlet port 140, and division wall 15 still can block the steam in the reservoir 13 and flow to inlet port 140, is favorable to reducing the risk that air vent 140 is blocked.

The partition wall 15 includes two sub-partition walls 151 located at two sides of the air intake column 14, wherein first ends of the two sub-partition walls 151 are connected to the side wall of the reservoir 13, and second ends are spaced apart to form the opening 150. In this embodiment, the end face of the bracket 10 is oval, the air inlet column 14 is disposed near the long side of the oval, the opening 150 is located on the short axis of the oval, and the two sub-partition walls 151 are both semi-circular arcs and symmetrically disposed on the two opposite sides of the air inlet column 14.

In this embodiment, by disposing the isolation tank 16 between the air intake column 14 and the sidewall of the liquid storage tank 13, the isolation tank 16 can block the liquid on the sidewall of the liquid storage tank 13 from flowing into the area of the air intake column 14, thereby reducing the source of the liquid around the air intake hole 140.

Specifically, the isolation tank 16 is communicated with the liquid storage tank 13 through the opening 150, and the isolation tank 16 can guide the contained liquid into the liquid storage tank 13, so as to prevent the liquid stored in the isolation tank 16 from overflowing and entering the air inlet hole 140.

Further, the bottom wall of the isolation tank 16 may be a plane or a flow guiding inclined wall, when the bottom wall of the isolation tank 16 is the flow guiding inclined wall, the lowest position of the flow guiding inclined wall is close to the liquid storage tank 13, and the liquid in the isolation tank 16 is guided to the liquid storage tank 13 along the flow guiding inclined wall, so that the liquid guiding effect of the isolation tank 16 is increased.

Specifically, the reservoir 13 is used to store liquid that leaks into the power module 100; the air hole 140 on the air inlet column 14 is communicated with the airflow sensing part 20, and when the electronic atomization device 300 is used, the airflow sensing part 20 senses airflow change in the electronic atomization device 300 through the air inlet hole 140, and feeds back a signal to the control board 40, so as to control the electrical core 30 to supply power to the atomizer 200.

The above-mentioned structure of the partition wall 15 and the partition groove 16 is mainly used to block the path of the liquid flowing into the air inlet hole 140, and when the port of the air inlet hole 140 faces the atomizer 200, the leakage liquid in the atomizer 200 is easy to directly drop into the air inlet hole 140, thereby blocking the air inlet hole 140. Therefore, in order to further reduce the risk that the air inlet hole 140 is blocked by liquid, referring to fig. 4-8, the power supply module provided by the present application further includes a blocking piece 17, the blocking piece 17 is disposed at the port of the air inlet hole 140 facing the atomizer 200 and blocks the port, so as to block liquid leakage in the atomizer 200 from directly dropping into the air inlet hole 140, the side wall of the air inlet column 14 forming the air inlet hole 140 has an air inlet 141 (see fig. 8) for air inlet, the air flow sensing piece 20 senses the change of air flow in the electronic atomization device 300 through the air inlet 141 on the side wall of the air inlet column 14 forming the air inlet hole 140, and feeds back a signal to the control board 40, thereby controlling the electric core 30 to supply power to the atomizer 200.

The position of the air inlet 141 on the air inlet column 14 has a certain distance from the bottom wall of the liquid storage tank 13, so that the accumulated liquid in the liquid storage tank 13 is prevented from excessively flowing into the air inlet 141.

The air inlet 141 may be an air guide through hole penetrating through a sidewall of the air inlet pillar 14 forming the air inlet hole 140, and the air inlet 141 may also be formed by the air inlet pillar 14 and the shielding member 17 in a matching manner.

In this embodiment, the air inlet 141 is formed by the air inlet post 14 cooperating with the shutter 17. Specifically, the end surface of the air inlet pillar 14 facing the atomizer 200 is provided with an air guiding groove 142, the air guiding groove 142 penetrates through the side wall of the air inlet hole 140, and the shielding member 17 is disposed on the end surface of the air inlet pillar 14 facing the atomizer 200 and covers the air guiding groove 142, so as to form the air inlet 141 by matching with the air inlet pillar 14 forming the air guiding groove 142.

Wherein, the ratio of the width of the air guiding groove 142 to the aperture of the air inlet hole 140 is 0.8-1.0, and the width of the air guiding groove 142 cannot be too small, which may cause the air flow sensing member 20 to be difficult to sense the air flow and the air pressure change in the electronic atomization device 300. For example, when the number of the air guide grooves 142 is two, the two air guide grooves 142 are disposed axially symmetrically along the air inlet hole 140, and the ratio of the width of the air guide groove 142 to the equal diameter of the air inlet hole 140 is 1.0. When the number of the air guide grooves 142 is greater than two, a plurality of air guide grooves 142 are circumferentially disposed around the air inlet hole 140, and the ratio of the width of each air guide groove 142 to the aperture of the air inlet hole 140 is appropriately reduced according to the number of the air guide grooves 142.

The air inlet 141 may face the partition wall 15, or may face the opening 150 of the partition wall 15. For example, in order to prevent the air inlet 141 from sucking the moisture-laden air in the sump 13, the air inlet 141 is directed toward the partition wall 15, and the sump 13 is blocked from the air inlet 141 by the partition wall 15, so that the air suction of the moisture-laden air into the air inlet 141 can be effectively reduced.

In an alternative embodiment, the number of the air inlets 141 is two, the two air inlets 141 face the two sub-partition walls 15, and the two air inlets 141 are arranged axially symmetrically along the air inlet hole 140. For example, the line connecting the two air inlets 141 is parallel to the major axis of the elliptical end face of the stent 10.

Referring to fig. 7, the shutter 17 includes a fixing portion 171 and a shielding portion 172, the fixing portion 171 being fixed to the holder 10 or the housing 50, the shielding portion 172 extending from the fixing portion 171 to a port of the intake hole 140 toward the nebulizer 200.

Specifically, the fixing portion 171 may be connected to the inner surface of the housing 50 or the bracket 10 by clipping, screwing or bonding. For example, the fixing portion 171 is a protrusion, and the housing 50 or the bracket 10 has a groove, and the protrusion and the groove are matched to realize connection. For another example, the fixing portion 171 has a male screw. The inner surface of the housing 50 or the bracket 10 has an internal thread, and the external thread is engaged with the internal thread to realize connection. For example, the fixing portion 171 is provided with an adhesive layer to be fixedly adhered to the inner surface of the housing 50 or the bracket 10.

One of the shielding portion 172 and the air inlet column 14 has a first engaging portion, and the other has a second engaging portion, and the first engaging portion and the second engaging portion engage with each other to fix the shielding portion 172 at the port of the air inlet hole 140 facing the atomizer 200. One of the first clamping part and the second clamping part can be a buckle, and the other can be a clamping groove. For example, the surface of the shielding portion 172 facing the air intake hole 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 with the air guide groove 142 and spaced from the bottom wall of the air guide groove 142, thereby forming the air inlet 141.

Or, the blocking portion 172 has a protrusion, which is disposed in the air inlet hole 140 and fixed to a sidewall of the air inlet hole 140 by interference fit. In this embodiment, the air inlet 141 is a through hole formed in a sidewall of the air inlet pillar 14 of the air inlet hole 140.

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

In some alternative embodiments, the material of the shield 17 may be rubber, silicone or plastic. The shield 17 may also be attached to the inner surface of the housing 50 or the bracket 10, for example by injection moulding integrally with the housing 50.

At least one vent 18 is opened on the side wall of the reservoir 13, wherein at least one vent 18 is provided at the position where the air inlet column 14 is embedded in the side wall of the reservoir 13, and then when the external atmosphere flows into the reservoir 13 through the vent 18, the external atmosphere directly passes through the air inlet column 14, so that the air inlet 141 can more directly and efficiently detect the air flow condition.

For example, when the sidewall of the reservoir 13 is opened with a vent 18, the vent 18 is disposed at a position where the air inlet pillar 14 is embedded in the sidewall of the reservoir 13, or is disposed at two sides of the reservoir 13 symmetrically to the notch 131. When the sidewall of the liquid storage tank 13 is provided with two air vents 18, one of the air vents 18 is disposed at a position where the sidewall of the liquid storage tank 13 is embedded in the air inlet column 14, and the other air vent may be disposed symmetrically with the first air vent 18, or may be disposed at other positions of the sidewall of the liquid storage tank 13, which is not limited herein.

Specifically, when the atomizer 200 is applied with a suction operation, the external air enters the electronic atomizer 300 through the air vent 18 and flows into the atomizer 200 through the reservoir 13. Consequently, set up vent 18 through the position of inlaying air inlet column 14 at the lateral wall of reservoir 13, the outside air passes through air inlet 141 earlier, then flow into reservoir 13 and atomizer 200, compare and set up vent 18 in other positions on the lateral wall of reservoir 13, can prevent that the outside air from passing through reservoir 13 earlier, carry more steam, then flow through air inlet 141 and then block up air inlet 141, and then lead to the unable detection air current of air current response piece 20 to change, the problem that electronic atomization device 300 can not normally start.

In other embodiments, the notch 131 is not completely blocked by the shield 172, and the notch 131 serves as the vent 18 at the same time.

Different from the prior art, the power supply module and the electronic atomization device 300 of the application comprise a support 10 and a shielding member 17, specifically, one end of the support 10 is provided with an air inlet column 14 and a partition wall 15, the air inlet column 14 is provided with an air inlet hole 140, the partition wall 15 is at least partially arranged around the air inlet column 14, and a partition groove 16 is formed between the partition wall 15 and the air inlet column 14 and used for blocking the path of liquid flowing to the air inlet hole 140; the shutter 17 is arranged at the port of the air intake hole 140 facing the nebulizer 200 and blocks the port, thereby blocking the liquid from entering the air intake hole 140; wherein, the sidewall of the air inlet column 14 forming the air inlet hole 140 has an air inlet 141, so that the air flow sensing member 20 can sense the air pressure change of the air flow in the electronic atomization device 300 through the air inlet 141.
