AEROSOL GENERATION DEVICE AND HEATING ASSEMBLY THEREOF

The present invention relates to an aerosol generation device and a heating assembly thereof. The heating assembly comprises a bracket body and a heating body for heating an aerosol generation substrate, wherein the heating body is arranged in the bracket body in a penetrating manner, and a first end of the heating body extends from the bracket body; and a channel for the heating body to pass through is arranged in the bracket body, the channel penetrates the bracket body, and the channel is internally provided with a sealing member surrounding the outside of the heating body and at least partially making contact with the heating body. In the present invention, the first end of the heating body can be inserted into the aerosol generation substrate from a bottom end of the aerosol generation substrate, the aerosol generation substrate is heated to generate an aerosol, and the sealing member seals a gap between the heating body and the bracket body, such that the aerosol cannot pass through the bracket body and
