Most of the air entering from the air inlet 500 enters the atomizing channel 400 , and a small part can enter the air supply channel 70 through the communication groove 401 to replenish air for the liquid storage chamber 100 and avoid negative pressure.

The air supplement channel 70 is specifically arranged on the first seat body 411 of the atomization seat 41 , and runs through two opposite surfaces of the first seat body 411 .

The two conductors 53 of the bottom case assembly 50 are respectively located on both sides of the air inlet 500 , one end of the conductors 53 is inserted into the bottom case 51 , and the other end is inserted into an air supply channel 70 , which simplifies the structure and assembly process. Correspondingly, a plurality of grooves 74 surrounding the conductor 73 are provided in the air supply passage 70 , and the plurality of grooves 74 are connected to each other and communicate with the air supply passage 70 and the communication groove 401 . The multi-channel grooves 74 are set in the gas supply channel 70 in the form of a labyrinth groove. There is a small ventilation groove at the bottom of the labyrinth tank to communicate with the communication groove 401, and the gas can be introduced into the labyrinth tank by using the capillary principle, and enter through the gas supply channel 70. The liquid storage bin 100 realizes air replenishment.

As shown in FIG. 9 , the atomizing device according to the fifth embodiment of the present invention includes a hollow shell 10 , a suction nozzle 20 , an air duct 30 , an atomizing unit 40 , a bottom shell assembly 50 and a liquid injection plug 60 . For the coordination and specific configuration of each structure, reference may be made to the above-mentioned fourth embodiment, and details are not repeated here.

What is different from the fourth embodiment above is that the air supplement valve further includes a pressure head 75 . The pressure head 75 is arranged on the surface of the first seat body 411 of the atomization seat 41 facing the liquid storage chamber 100 corresponding to the air supply channel 70 , and the pressure head 75 can be opened and closed relative to the first seat body 411 to open or close the air supply channel 70 .

One end of the pressure head 75 is connected to the surface of the first base body 411, and the other end can rotate up and down relative to the first base body 411 to realize the opening and closing of the pressure head 75 on the air supply channel 70, further enhancing the leak-proof function.

The pressure head 75 can be made of elastic materials such as silica gel.

When the atomizers of the above-mentioned fourth and fifth embodiments are in operation, the air pressure in the oil storage bin 100 decreases due to the consumption of e-liquid. At this time, the air supply valve is opened, and the gas enters from the air inlet 500 through the communication grooves 401 on both sides. The groove 74 enters the air supplement channel 70, and then pushes away the pressure head 75 to enter the liquid storage chamber 100, so as to realize the balance between the liquid storage chamber 100 and the external pressure, and then realize timely and sufficient liquid supply. At the same time, the phenomenon of liquid leakage caused by the change of air pressure inside and outside the liquid storage bin 100 is avoided, and the leak-proof function is enhanced.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, all of which are equally included in the scope of patent protection of the present invention.
