Optionally, referring to fig. 5, the air hole 140 may also be disposed on a side wall of the air inlet column 14, and the drainage structure 15 is disposed around the air hole 140, so as to prevent condensate on the atomizer 200 from directly dropping into the air inlet hole 140.

In one embodiment, the air inlet hole of the atomizer 200 is disposed substantially opposite to the center of the reservoir 13, and the position of the air inlet pillar 14 is offset from the position of the air inlet hole of the atomizer 200 to prevent leakage from falling into the air hole 140.

Alternatively, the air inlet column 14 may be disposed in the reservoir 13, that is, the air inlet column 14 is connected to the bottom wall of the reservoir 13, and the air inlet column 14 is disposed at a distance from the sidewall 132 of the reservoir 13; alternatively, the air intake column 14 may also be partially or completely embedded in the side wall 132 of the reservoir 13, thereby allowing a greater distance from the air intake of the atomizer 200, which may significantly reduce the risk of leakage into the air holes 140.

The air inlet hole on the atomizer 200 is opposite to the liquid storage tank 13, and the liquid storage tank 13 is mainly used for containing leaked liquid leaked from the air inlet hole and preventing the leaked liquid from flowing to the battery core 30, the control panel 40 and other devices; the outside air flow passes through the liquid storage tank 13 and leads to the air inlet hole of the atomizer 200, and liquid such as water vapor and leakage carried by the air flow can be condensed on the end surface of the air inlet column 14, even the liquid on the end surface of the bracket 10 is guided to the air inlet column 14, so that the air hole 140 has a higher risk of being blocked.

As shown in fig. 4, the drainage structure 15 may be circular and may be disposed 360 degrees around the air hole 140; the flow directing structure 15 may also be partially disposed around the air hole 140, such as a semi-surrounding, which is not specifically limited in this application.

Optionally, drainage structure 15 can be drainage inclined plane 151 such as chamfer angle or radius angle, and drainage structure 15 can also be structures such as drainage groove or drainage hole, and it can reduce the area of the first terminal surface 141 of the one end that air inlet column 14 kept away from the diapire of reservoir 13 promptly to reduce the liquid gathering volume of first terminal surface 141, also be favorable to gathering in the leading-in to reservoir 13 of the liquid of first terminal surface 141, further reduce the liquid gathering volume of first terminal surface 141, can reduce the risk that liquid got into gas pocket 140 effectively.

Further, when the drainage structure 15 is the drainage inclined plane 151, an included angle between the drainage inclined plane 151 and the axis of the air hole 140 is greater than or equal to 30 degrees and less than or equal to 60 degrees, so as to increase the drainage efficiency of the drainage inclined plane 151. Optionally, the angle between the drainage bevel 151 and the axis of the air hole 140 may be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, or 60 degrees.

In the present application, the terms "first", "second" and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

As shown in fig. 5, the air hole 140 is disposed on the sidewall of the air inlet column 14, and the drainage structure 15 may also be a drainage groove and disposed around the air hole 140 to guide the liquid flowing to the air hole 140 to the reservoir 13.

Specifically, the reservoir 13 is used to store liquid that leaks into the power module 100; the air holes 140 on the air inlet column 14 are communicated with the airflow induction part 20, when the atomizer 200 is applied with a suction operation, the airflow induction part 20 induces airflow change in the electronic atomization device through the air holes 140, and feeds back a signal to the control board 40, so as to control the battery core 30 to supply power to the atomizer 200; the drainage structure 15 is used for guiding the liquid collected at the end, away from the bottom wall of the liquid storage tank 13, of the air inlet column 14 to the liquid storage tank 13, so that the excessive liquid is prevented from being collected at the end face, away from the bottom wall of the liquid storage tank 13, of the air inlet column 14, the risk that the liquid blocks the air hole 140 can be remarkably reduced, the phenomenon that the airflow induction piece 20 cannot induce airflow change is avoided, and the electronic atomization device 300 cannot be normally started.

In this embodiment, the air hole 140 is disposed at an end of the air inlet column 14 away from the bottom wall of the reservoir 13, and the drainage structure 15 is a drainage inclined plane 151 disposed around the air hole 140. For example, on the end of the intake column 14 remote from the bottom wall of the sump 13, a right angle or rounded is formed to form a drainage ramp 151.

It can be understood that the one end that the reservoir 13 was kept away from to the air inlet column 14 is the chamfer design, then the one end that the reservoir 13 was kept away from to the air inlet column 14 is divided into first terminal surface 141 and drainage inclined plane 151, for not having the chamfer design, drainage inclined plane 151 can reduce the platform area of the terminal surface that the reservoir 13 was kept away from to air inlet column 14, and then reduce the liquid gathering volume of liquid on air inlet column 14, and simultaneously, liquid also flows to reservoir 13 through drainage inclined plane 151 more easily, thereby reduce the risk that liquid flows into air pocket 140.

Further, the width of the first end surface 141 of the air intake column 14 away from the bottom wall of the reservoir 13 in the radial direction of the air hole 140 is greater than or equal to 0.1mm and less than or equal to 0.3mm, so that the air intake column 14 has certain strength, the accumulation amount of liquid on the first end surface 141 can be reduced, and the liquid on the air intake column 14 easily flows into the reservoir 13 through the drainage inclined surface 151.

Alternatively, the width of the first end surface 141 in the radial direction of the air hole 140 is 0.1mm, 0.2mm, or 0.3 mm.

In other embodiments, the drainage structure 15 may also be a plurality of drainage grooves disposed around the air hole 140, one end of each drainage groove is disposed on an end surface of the air inlet column 14 far away from the liquid storage tank 13, and the other end of each drainage groove extends toward the liquid storage tank 13, so as to guide the liquid on the air inlet column 14 into the liquid storage tank 13.

In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Further, an isolation tank 16 is formed between the intake column 14 and the side wall of the reservoir 13, and the isolation tank 16 is disposed at least partially around the intake column 14. By providing the isolation tank 16 between the air intake column 14 and the side wall of the reservoir 13, the isolation tank 16 can prevent the liquid on the side wall of the reservoir 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. When the isolation tank 16 is disposed completely around the intake column 14, the isolation tank 16 may also be used to contain the liquid flowing into the side walls of the intake column 14 and the liquid storage tank 13, and corresponds to a sub-liquid storage tank.

Optionally, an isolation tank 16 is disposed around the intake column 14, and the isolation tank 16 is isolated from the reservoir 13, the isolation tank 16 storing the liquid diverted from the intake column 14. The side wall of the isolation tank 16 near the reservoir 13 is lower than the side walls of the air inlet column 14 and the reservoir 13, so that when the liquid contained in the isolation tank 16 is full, the liquid in the isolation tank 16 can overflow the isolation tank 16 and flow into the reservoir 13.

In one embodiment, the isolation tank 16 is further connected to the reservoir 13, and the isolation tank 16 can guide the contained liquid into the reservoir 13, thereby preventing the liquid stored in the isolation tank 16 from overflowing and entering the air 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 part 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.

Further, one end of the bracket 10 is further provided with a partition wall 17, the partition wall 17 is arranged around the air inlet column 14, the partition groove 16 is arranged between the partition wall 17 and the air inlet column 14, an opening 18 is formed in the partition wall 17, and the partition groove 16 is communicated with the liquid storage tank 13 through the opening 18.

Through setting up the division wall 17, can further increase the degree of difficulty that the liquid on the terminal surface of support 10 flowed to gas pocket 140, and division wall 17 still can block the steam in the reservoir 13 and flow to gas pocket 140, is favorable to reducing the risk that gas pocket 140 is blocked.

Optionally, the partition wall 17 surrounds the air inlet column 14, and when the air inlet column 14 and the side wall of the liquid storage tank 13 are arranged at intervals, the partition wall 17 may also be arranged at intervals with the side wall of the liquid storage tank 13; the partition wall 17 may also be integrally formed with the side wall of the partition groove 16.

Alternatively, the opening 18 is a through hole provided on the partition wall 17 on a side close to the reservoir 13, through which the liquid in the partition tank 16 flows into the reservoir 13.

In this embodiment, the opening 18 is a notch extending from the end surface of the partition wall 17 away from the bottom wall of the reservoir 13 to the bottom wall of the reservoir 13. The opening 18 is arranged to be a notch, so that the processing difficulty can be reduced, and the flow guide effect is better.

The air inlet column 14 is at least partially embedded in the side wall of the liquid storage tank 13, a partition wall 17 is formed on the side wall of the liquid storage tank 13, the partition wall 17 comprises a ring blocking portion 171, the ring blocking portion 171 extends into the liquid storage tank 13 from the side wall of the liquid storage tank 13, and an opening 18 is formed in the ring blocking portion 171.

Specifically, the air inlet column 14 is partially embedded in the side wall of the reservoir 13, the partition wall 17 is in a ring shape with an opening 18, a part of the partition wall 17 is embedded in the side wall of the reservoir 13, the other part of the partition wall 17 extends into the reservoir 13 to form a ring stop 171, and the opening 18 communicates with the reservoir 13 and the partition tank 16.

In other embodiments, the air intake column 14 may also be completely embedded in the side wall of the reservoir 13, the partition wall 17 is disposed around the air intake column 14, and a side of the partition wall 17 facing the reservoir 13 has an opening 18 for introducing the liquid in the partition tank 16 into the reservoir 13.

Referring to fig. 6, the sidewall of the liquid storage tank 13 is provided with at least one air inlet 131, wherein there is at least one air inlet 131 disposed at a position where the air inlet column 14 is embedded in the sidewall of the liquid storage tank 13, and when the external atmosphere flows into the liquid storage tank 13 through the air inlet 131, the external atmosphere directly passes through the air inlet column 14, so that the air hole 140 can detect the air flow condition more directly and efficiently.

For example, when the sidewall of the liquid storage tank 13 is opened with an air inlet 131, the air inlet 131 is disposed at a position where the air inlet column 14 is embedded in the sidewall of the liquid storage tank 13. When the sidewall of the liquid storage tank 13 is provided with two air inlets 131, one of the air inlets 131 is disposed at the position where the air inlet column 14 is embedded in the sidewall of the liquid storage tank 13, and the other one may be disposed symmetrically with the first air inlet 131, 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 atomization device 300 through the air inlet 131 and flows into the atomizer 200 through the reservoir 13. Therefore, the air inlet 131 is arranged at the position where the air inlet column 14 is embedded in the side wall of the liquid storage tank 13, the external air firstly passes through the air hole 140 and then flows into the liquid storage tank 13 and the atomizer 200, compared with the air inlet hole 140 arranged at other positions on the side wall of the liquid storage tank 13, the situation that the external air firstly passes through the liquid storage tank 13 and carries more water vapor can be prevented, and then the external air flows through the air hole 140, and is deposited in the area around the air hole 140 to block the air hole 140, so that the air flow sensor 20 cannot detect the change of the air flow, and the electronic atomization device 300 cannot be started normally.

Further, at least one air suction hole 51 is formed in the housing 50, and the air suction hole 51 is used for guiding the external air into the electronic atomization device 300. It can be understood that the at least one air suction hole 51 is disposed in one-to-one correspondence with the at least one air inlet 131, so as to reduce the suction resistance of the electronic atomization device 300.

In the present embodiment, the first end surface 141 of the air inlet column 14 is higher than the second end surface 172 of the partition wall 17, wherein the second end surface 172 is the end surface of the partition wall 17 away from the bottom wall of the liquid storage tank 13, so that the liquid in the partition tank 16 can be prevented from overflowing into the air hole 140.
