Differential pressure type electronic cigarette gas pressure sensor and electronic cigarette

The invention discloses a differential pressure type electronic cigarette gas pressure sensor and an electronic cigarette. The differential pressure type electronic cigarette gas pressure sensor comprises a PCB; a shell installed on the PCB, wherein the space between the shell and the PCB is divided into two ventilation cavities; a chip arranged on the PCB, positioned in a first cavity and used for processing air pressure data; a first air pressure sensing element used for detecting external air pressure; and a second air pressure sensing element mounted on the PCB, positioned in a second cavity and used for detecting the air suction pressure of a user. The two air pressure sensing elements are integrated on the same air pressure sensor, the air pressure sensor is arranged to be of a double-cavity type, and the two air pressure sensing elements are located in different cavities respectively, so that the external air pressure and the air pressure on an air suction channel can be compared in time to generate an
