Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0028] See also Figure 1 and Figure 2 In one embodiment, the present application proposes an electronic atomization device, including: a shell 10, a protrusion 20, and a power supply component 30.

[0029] The housing 10 has a receiving cavity 11 and an air inlet 12;

[0030] The convex portion 20 is disposed in the accommodating cavity 11 and is located at the air inlet hole 12. The convex portion 20 has a top surface 21 and a side surface 22. The top surface is disposed opposite to the air inlet hole 12. The side surface 22 is provided with a vent hole 221. The vent hole 221 communicates with the accommodating cavity 11 and the air inlet hole 12.

[0031] The power supply assembly 30 is disposed in the accommodating cavity 11 , and is in contact with the top surface 21 or spaced apart from the top surface 21 .

[0032] The shell 10 may be made of plastic, and the air outside the electronic atomization device may enter the electronic atomization device through the air inlet 12, thereby participating in the atomization reaction inside the electronic atomization device, forming an aerosol with the aerosol product and finally being sucked through the nozzle.

[0033] The convex part 20 can be designed as an integrally formed structure with the housing 10, thereby simplifying parts and facilitating assembly, wherein the air inlet 12 can be a circular hole, the vent 221 can be a circular hole or a square hole, and the area of ​​the vent 221 can be greater than or equal to the cross-sectional area of ​​the air inlet 12. Furthermore, the vent 221 extends to the top surface, thereby reducing the circulation of airflow in the convex part 20 and reducing noise.

[0034] The power supply assembly 30 may include a battery and a circuit board, etc. The battery may be located above the top surface 21 or abut against the top surface 21 .

[0035] In this way, the air inlet hole 12 can be prevented from being directly connected to the accommodating cavity 11 in its extending direction. The convex portion 20 can prevent the internal structure from being directly seen through the air inlet hole 12 from the outside of the electronic atomization device, and can also prevent the risk of the battery assembly in the accommodating cavity 11 being punctured by external foreign objects. Furthermore, a vent hole 221 is provided on the side 22 to prevent the battery assembly in the accommodating cavity 11 from blocking the air inlet hole 12, thereby making the airflow of the air inlet hole 12 more stable.

[0036] See also Figure 1 and Figure 2 In one embodiment, the cross-sectional area of ​​the air inlet 12 is greater than or equal to 5 square millimeters, and the distance between the end of the air inlet 12 located on the outer surface of the housing 10 and the top surface 21 is greater than or equal to 1.5 millimeters. This can avoid airflow sound and whistling sound, making the electronic atomization device more convenient to use.

[0037] See also Figure 1 and Figure 2 In one embodiment, the convex portion 20 is a bent structure, one end of which is connected to the inner wall of the accommodating cavity 11, and the other end is arranged opposite to the air inlet 12. This can make the structure of the convex portion 20 simpler and facilitate integral molding, and can also make the area of ​​the vent hole 221 larger, which is convenient for smoother ventilation.

[0038] See also Figure 1 and Figure 2 In one embodiment, the orthographic projection area of ​​the top surface 21 facing the vent hole 221 is larger than the cross-sectional area of ​​the vent hole 221. In this way, the vent hole 221 can be completely shielded to prevent the internal structure from being directly seen through the air inlet 12 from outside the electronic atomization device, and also to prevent the risk of the battery assembly in the accommodating cavity 11 being punctured by external foreign objects.

[0039] See also Figure 2 and Figure 3 In one embodiment, the housing 10 includes a bottom housing 13, and the air inlet 12 is disposed in the bottom housing 13. The bottom housing 13 may be made of plastic material, and the bottom housing 13 is located at the lower end of the housing 10. The air inlet 12 is located in the bottom housing 13 to prevent the hand holding the electronic atomization device from blocking the air inlet 12, thereby ensuring smoother air intake.

[0040] See also Figure 2 In one embodiment, the electronic atomization device further includes a gasket 40, which is disposed in the bottom shell 13, and a side of the power supply assembly 30 close to the air inlet 12 abuts against the gasket 40. The gasket 40 can be made of rubber or foam material, and the power supply assembly 30 can be supported by the gasket 40, which facilitates the positioning and installation of the power supply assembly 30, such as a battery, and can prevent the battery from pressing the top surface 21, thereby ensuring the stability of the electronic atomization device.

[0041] See also Figure 2 In one embodiment, the bottom shell 13 is provided with a mounting groove 131, and the gasket 40 is partially placed in the mounting groove 131. The mounting groove 131 can facilitate the positioning and installation of the gasket 40, and the assembly is faster and more convenient.

[0042] See also Figure 2 In one embodiment, the height of the gasket 40 is greater than the height of the top surface 21. Thus, the battery of the power supply assembly 30 can be spaced apart from the top surface 21 to prevent the battery from pressing the top surface 21, thereby further improving the stability of the electronic atomization device.

[0043] See also Figure 2 In one embodiment, the electronic atomization device further includes a cartridge 50, which is partially placed in the accommodating chamber 11, and the cartridge 50 is located at an end of the power supply assembly 30 away from the air inlet 12. External air enters the accommodating chamber 11 through the air inlet 12 and then through the vent 221, and then enters the cartridge 50 to participate in the atomization reaction. The design of the cartridge 50 allows the replacement of the oil, which is more convenient to use.

[0044] In specific implementation, the above units or structures can be implemented as independent entities, or can be arbitrarily combined to be implemented as the same or several entities. The specific implementation of the above units or structures can refer to the previous method embodiments, which will not be repeated here.
