Description

CROSS-REFERENCE TO PRIOR APPLICATION This application is a continuation of International Patent Application No. PCT/CN2020/089824, filed on May 12, 2020. The entire disclosure is hereby incorporated by reference herein. FIELD This application relates to the field of vaporization device technologies, and in particular, to a vaporization device. BACKGROUND Currently, a cavity wall of a vaporization cavity in a vaporization device such as an e-cigarette is made of a plastic material. When the temperature in the vaporization cavity is excessively high, stability problems such as deformation, and even scorching of the cavity wall of the vaporization cavity are usually caused. Moreover, when the vaporization device heats and vaporizes an aerosol substrate such as e-liquid, an oil frying phenomenon is prone to occur due to uneven distribution of the aerosol substrate and high local temperature. The non-vaporized aerosol substrate splashes to the cavity wall of the vaporization cavity, or the vaporized aerosol substrate condenses on the cavity wall of the vaporization cavity. The aerosol substrate attached to the cavity wall of the vaporization cavity may reach the bottom of the vaporization device along the cavity wall, causing a liquid leakage problem. SUMMARY In an embodiment, the present invention provides a vaporization device, comprising: an air inlet; an air outlet; a vaporization cavity in communication with the air inlet and the air outlet, a vaporization assembly being arranged in the vaporization cavity; and a first capillary liquid absorbing structure arranged on a part of the inner wall of the vaporization cavity close to the vaporization assembly, wherein, after the first capillary liquid absorbing structure absorbs an aerosol substrate, a temperature of the cavity wall of the vaporization cavity at a position where the first capillary liquid absorbing structure is located is lowerable with endothermic vaporization of the aerosol substrate.
