Vaporizer and aerosol generation apparatus

Abstract

This application provides a vaporizer and an aerosol generation apparatus. The vaporizer includes a housing, where the housing has a liquid storage cavity and a first air outlet channel; a fixing bracket, mounted inside the housing, where the fixing bracket has a liquid guide portion extending toward the liquid storage cavity, where at least a part of a surface of the liquid guide portion that faces toward the first air outlet channel is recessed to form a first recessed portion; and a vaporization assembly, fixedly mounted on the fixing bracket, and being in fluid communication with the liquid storage cavity through the liquid guide portion, where the vaporization assembly is configured to vaporize the liquid substrate to form the aerosol. In the vaporizer, a structural design of the fixing bracket and a design of the air outlet channel are simplified, so that the whole structure is simpler.
