In one of the embodiments, the isolation tank 16 is also connected to the liquid storage tank 13, and the isolation tank 16 can guide the liquid contained in the liquid storage tank 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 can be a plane or a diversion inclined wall. When the bottom wall of the isolation tank 16 is a diversion inclined wall, the lowest point of the diversion inclined wall is close to the liquid storage tank 13, and in the isolation tank 16 The liquid is guided to the liquid storage tank 13 along the guide inclined wall, which increases the liquid guide effect of the isolation tank 16.

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

By arranging the partition wall 17, it is possible to further increase the difficulty of the liquid on the end surface of the bracket 10 flowing to the air hole 140, and the partition wall 17 can also prevent the water vapor in the liquid storage tank 13 from flowing to the air hole 140, which is beneficial to reduce the possibility that the air hole 140 is blocked. risk.

Optionally, the partition wall 17 surrounds the air inlet column 14, and when the side wall of the air inlet column 14 and the liquid storage tank 13 is spaced apart, the partition wall 17 can also be spaced apart from the side wall of the liquid storage tank 13; the partition wall 17 can also be It is integrally formed with the side wall of the isolation groove 16 .

Therefore, by setting the air inlet 131 at the position where the air intake column 14 is embedded on the side wall of the liquid storage tank 13, the outside air first passes through the air hole 140, and then flows into the liquid storage tank 13 and the atomizer 200. Air intake holes 140 are provided at other positions on the side wall of the liquid tank 13, which can prevent outside air from passing through the liquid storage tank 13 first, carrying more water vapor, and then flowing through the air holes 140, and depositing in the area around the air holes 140, blocking The air hole 140 further leads to the problem that the airflow sensor 20 cannot detect the airflow change, and the electronic atomization device 300 cannot be started normally.

Further, the housing 50 is provided with at least one air suction hole 51, and the air suction hole 51 is used to conduct the outside air into the electronic atomization device 300. It can be understood that at least one suction hole 51 is provided in a one-to-one correspondence with at least one air inlet 131 , which can reduce the suction resistance of the electronic atomization device 300 .

In this 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, which can avoid isolation. The liquid in the tank 16 overflows into the air holes 140 .

And when the user has a suction action, the partition wall 17 can block the gas flowing from the area of the liquid storage tank 13 to the air hole 140, and then at least part of the water vapor carried by the air flow can be removed, and it is also beneficial for the water vapor to flow on the partition wall 17. Condensation effectively reduces the water vapor carried by the airflow flowing to the intake column 14 , thereby reducing the condensation of water vapor on the first end surface 141 , which is beneficial to reducing the risk of liquid blocking the air hole 140 .

Further, the height difference between the first end surface 141 and the second end surface 172 is in the range of 0.2 mm to 0.4 mm, and within this range, the partition wall 17 can effectively block water vapor from flowing to the intake column 14 .

It can be understood that the first end surface 141 is lower than the third end surface 133 , and the first end surface 141 is higher than the second end surface 172 , that is, when the atomizer 200 is connected to the power supply assembly 100 , the end of the atomizer 200 close to the bracket 10 is connected to the second end surface 172 . The abutment of the three end surfaces 133 can avoid the interference between the air intake column 14 and the abutting surface of the atomizer 200 , and further, the airflow condition can be detected by utilizing the gap between the first end surface 141 and the abutting surface of the atomizer 200 .

Referring to Fig. 7, Fig. 7 is a cross-sectional view of part of the structure along the line B-B when the bracket shown in Fig. 3 is connected to the atomizer. Reducing the cut-off distance C of the air hole 140 is beneficial to reduce the formation of aerosol condensate in the air hole 140 .

Specifically, the aerosol of the atomizer 200 is easy to overflow into the liquid storage tank 13. If the height difference between the third end surface 133 and the first end surface 141 is large, that is, the distance between the contact surface of the air hole 140 and the atomizer 200 The cut-off distance between them is also larger, which makes it easier for the aerosol to flow to the air hole 140 and condense in the air hole 140, resulting in blocking the air hole 140. That is, within this numerical range, the cut-off distance of the air intake column 14 can be made smaller, which can detect the airflow condition, and can also prevent a large amount of aerosol from flowing to the air hole 140, effectively reducing the condensate in the air hole 140. Formation.

For example, the height difference between the third end surface 133 and the first end surface 141 may be 0.06mm, 0.07mm, 0.08mm, 0.09mm or 0.1mm.

In the bracket 10 provided by the present application, one end of the bracket 10 is provided with an air intake column 14 having a drainage slope 151, a partition wall 17 and an isolation groove 16, thereby forming a moat structure on the side of the intake column 14. Through the moat structure, the reduction of The source of the liquid flowing to the air inlet column 14 blocks the path of the liquid entering the air hole 140 , which significantly reduces the risk of the air hole 140 being blocked, and can ensure the normal start-up of the electronic atomization device 300 .

Further, the second end surface 172 of the partition wall 17 is set lower than the first end surface 141 of the intake column 14, and the height difference between the first end surface 141 and the second end surface 172 is in the range of 0.2mm to 0.4mm; the first The end surface 141 is lower than the third end surface 133 of the side wall of the liquid storage tank 13, and the height difference between the third end surface 133 and the first end surface 141 is in the range of 0.06mm to 0.1mm, that is, the air inlet column 14 and the atomizer 200 The distance is 0.06mm-0.1mm; when the atomizer 200 is subjected to suction operation, it can effectively prevent the aerosol from entering the area of the air intake column 14, and the airflow sensor 20 through the air hole 140 is more to detect the supplementary inflow from the outside The flow state of the air can significantly reduce the formation of condensate in the air holes 140 .
