[0039] like Figure 1-4 As shown, the embodiment of the utility model provides an air replenishing structure, which is applied to an electronic atomization device, the electronic atomization device comprises a liquid storage cup 1, a bracket assembly 2 inserted in a port of the liquid storage cup 1, and a base 3 buckled with the bracket assembly 2 to form an atomization chamber, the air replenishing structure comprises:

[0040] An air supply channel 21 is provided on the support assembly 2, and two ends of the air supply channel 21 are respectively connected to the atomizing chamber and the liquid storage cup 1;

[0041] A blocking structure 31 is arranged on the base 3 and extends into the air supply channel 21, and a one-way flow channel 4 is constructed between the air supply channel 21 and the blocking structure 31. Both ends of the one-way flow channel 4 are respectively connected to the atomization chamber and the part of the air supply channel 21 located on the side of the blocking structure 31 away from the base 3. The flow direction of the airflow in the one-way flow channel 4 is from the base 3 toward the bracket assembly 2.

[0042] In the present embodiment, the air replenishment structure includes an air replenishment channel 21 provided on the support assembly 2, a blocking structure 31 provided on the base 3 and extending into the air replenishment channel 21, and a one-way flow channel 4 constructed between the air replenishment channel 21 and the blocking structure 31; specifically, in the present embodiment, the two ends of the air replenishment channel 21 are connected to the atomization chamber and the liquid storage cup 1 respectively, a blocking structure 31 extending into the air replenishment channel 21 is provided on the base 3, and a one-way flow channel 4 is constructed between the air replenishment channel 21 and the blocking structure 31, the two ends of the one-way flow channel 4 are respectively connected to the atomization chamber and the part of the air replenishment channel 21 located on the side of the blocking structure 31 away from the base 3, and the flow direction of the airflow in the one-way flow channel 4 is from the base 3 to the liquid storage cup 1. Towards the bracket assembly 2, when there is no ventilation, the one-way flow channel 4 can automatically close the air supply channel 21. During ventilation, when the atomized liquid in the liquid storage cup 1 is consumed less due to work, the pressure in the liquid storage cup 1 is reduced, and the one-way flow channel 4 allows air to enter the liquid storage cup 1. The pressure inside the liquid storage cup 1 reaches equilibrium after the air enters, and the one-way flow channel 4 closes the air supply channel 21. Therefore, the air supply structure of this embodiment can open the air supply channel 21 when the negative pressure in the liquid storage cup 1 is less than a preset value. The air supply structure of this embodiment enables the ventilation airway to achieve ventilation at the shortest distance, and the cross-section of the ventilation airway can be made relatively large, and the ventilation sensitivity is high, ensuring timely ventilation, thereby avoiding defects such as drying or sticking of the atomizer core.

Compared with the sealing silicone rubber 7 with a pressure relief groove provided on the periphery, the air supply path of the air supply channel 21 of this embodiment is shorter and the air supply is faster.

[0049] In this embodiment, the unidirectional flow of the unidirectional flow channel 4 is achieved by using the Tesla valve flow channel structure.

[0050] In some embodiments, an air inlet hole 34 is opened on the base 3 so that the side of the base 3 away from the liquid storage cup 1 is connected to the atomization chamber, forming an air inlet path of the atomization chamber; the side of the base 3 facing the bracket assembly 2 is constructed with a first annular protrusion 35 surrounding the air inlet hole 34 to form a liquid storage space 36 between the inner wall of the base 3 and the outer wall of the first annular protrusion 35.

[0051] In this embodiment, the liquid storage space 36 can store the atomized liquid seeping out due to ventilation, ensuring that the seeping atomized liquid does not affect the ventilation function, thereby avoiding defects such as the atomizer core drying out or sticking.

[0052] In some embodiments, at least two electrodes 6 connected to the atomizer core 5 are inserted on the base 3, and the electrodes 6 extend from the atomizer core 5 to a side of the base 3 away from the liquid storage cup 1.

[0057] In some embodiments, the liquid storage cup 1 is constructed with an air outlet pipe 11 at one end connected to the outside. When the air replenishment structure includes an air outlet channel 22, the other end of the air outlet pipe 11 is plugged into the other end of the air outlet channel 22 to form an air outlet path for the atomization chamber.
