| description | The invention discloses an electronic cigarette gas pressure sensor and an electronic cigarette. The sensor comprises a shell, a circuit board, an ASIC chip and a gas pressure sensing element; the circuit board is provided with a first gas hole; the gas pressure sensing element comprises a base and a piezoelectric film; the base forms a gas cavity, and the first gas hole is communicated with the gas cavity; the piezoelectric film gradually inclines from the end connected with the base to the direction away from the gas cavity; the shell and the circuit board are welded through solder paste; the piezoelectric film and the ASIC chip are connected through a wire; the ASIC chip and the circuit board are bonded and fixed; and the first air holes and the second air holes are staggered. Compared with the prior art, the electronic cigarette gas pressure sensor has the advantages that the defect that oil or water drops on the surface of the piezoelectric film to generate electric signals mistakenly can be well prevent |
