Description

TECHNICAL FIELD

[0001] The present application belongs to the field of electronic atomization equipment, and particularly relates to an air flow heat dissipation structure and an aerosol generating device with the same. BACKGROUND

[0002] The aerosol generating device is an electronic product for users to use, which atomizes aerosol base into misty aerosol by using a heating body assembly. Meanwhile, the aerosol generated by the aerosol generating device does not contain tar, suspended particles and other harmful components, so it has a wide application market. In the aerosol generating device, the heating body assembly is a very important part. When the power assembly supplies power to the heating body assembly to make the heating body assembly heat up, the power assembly itself will also generate heat. In the existing aerosol generating device, the heating body assembly is usually located at the position of the air inlet channel. When the air flow passes through, it can drive the aerosol to flow out and also cool the heating body assembly, thereby protecting the heating body assembly to a certain extent. However, in the prior art, the heating body assembly is not always located at the air inlet channel, so the heat generated by the heating body assembly that is not located at the air inlet channel cannot be dissipated in time, thereby causing local overheating of the heating body assembly. In addition, the heat generated by the power assembly will cause excessive heating. SUMMARY

[0003] The purpose of the present application is to provide an air flow heat dissipation structure and an aerosol generating device with the same, which can not only dissipate heat from the power assembly, but also dissipate heat from the local heating body assembly, thereby having a better heat dissipation effect and avoiding the problem of excessive heating.

[0004] To achieve the above-mentioned purpose, the present application is implemented by the following technical scheme: an air flow heat dissipation structure is provided, which comprises a shell, a support arranged in the shell, and a power assembly arranged in the shell and located at the lower end of the support. A supporting member for mounting an air duct is arranged in the support. A heating body assembly is further arranged on the support. The heating body assembly penetrates through the supporting member and extends into the air duct. A containing cavity is formed between the support, the heating body assembly and the supporting member. The containing cavity is in communication with the air duct. A cavity in communication with the containing cavity is arranged on the heating body assembly. A passageway is formed between the power assembly and the shell. An air inlet hole is arranged at the bottom of the shell. The passageway is in communication with the cavity and the air inlet hole.

[0005] Further, the heating body assembly comprises a heating body fixing seat arranged on the support and a heating body arranged on the heating body fixing seat. The cavity is arranged on the heating body, and the cavity is located at the lower end of the supporting member.

[0006] Furthermore, the lower end of the bracket is provided with a channel, and the heating element fixing seat is provided with a through hole communicating with the channel. The channel is connected to the air inlet, and the through hole is connected to the cavity.

[0007] Furthermore, the heating element is provided with an air inlet, which is connected to both the through hole and the cavity.

[0008] Furthermore, the heating element is provided with multiple air outlets, which are connected to both the cavity and the accommodating cavity, and at least one of the air outlets is located on the side wall of the heating element.

[0009] Furthermore, there are two air outlets, which are symmetrically distributed on the side wall of the heating element, and the direction of the two air outlets is perpendicular to the direction of the air passage.

[0010] Furthermore, the lower end of the support member is provided with a through hole, which is connected to both the accommodating cavity and the air passage; the size of the through hole is larger than the size of the heating element, and the heating element passes upward through the through hole and extends into the air passage.

[0011] Furthermore, the power supply assembly includes a battery cell disposed at the lower end of the bracket and a control board electrically connected to the battery cell, the heating element being electrically connected to the control board, and the passage being formed between the battery cell and the control board and the outer casing.

[0012] An aerosol generating device is also provided, including the airflow cooling structure described above.

[0013] Furthermore, the housing is provided with a button hole and a connection hole. The button hole contains a button that is electrically connected to the power supply component, and the connection hole contains a socket that is electrically connected to the power supply component.

[0014] The present invention has the following beneficial effects:

[0015] The airflow heat dissipation structure can dissipate heat of the power supply assembly when air flows through the channel, and take away the generated heat. After the air flows into the cavity, the air flows through the accommodating cavity arranged between the heating body assembly and the supporting piece, and finally flows into the air channel through the supporting piece, so that the aerosol substrate is taken out from the air channel. Since the external air can flow through the cavity arranged on the heating body assembly, the external air flows through the heating body assembly between the support and the supporting piece, so that the heating body assembly between the support and the supporting piece can be cooled, the heating body assembly at the position can be better cooled, and the problem of overheating of the heating body assembly caused by local high temperature is reduced. Therefore, the airflow heat dissipation structure of the embodiment of the present application can not only dissipate heat of the power supply assembly, but also dissipate heat of the heating body assembly locally, has a better heat dissipation effect, and will not have the problem of excessive heating.

[0016] The aerosol generating device provided by the present application is designed based on the airflow heat dissipation structure described above, and the beneficial effects thereof are described above. BRIEF DESCRIPTION OF DRAWINGS
