Abstract: This invention relates to a tobacco vaporizer, which belong to the technical field of electro-heating technology. The tobacco vaporizer includes an vaporizer, a battery rod and a PCB board. The tobacco vaporizer further includes a sealing part located between the vaporizer and the battery rod; a temperature measurement detector that one end of the temperature measurement detector is inserted in the sealing part and the other end of the temperature measurement detector is connected with the PCB board through the conductive wire. The tobacco vaporizer is simple in structure and easy to measure the temperature of the evaporation cavity.
