Abstract:
An electronic atomizer comprises an air pressure sensor, a control circuit, an electronic heating unit (R, R1), and a PTC self-recovery fuse 2. The air pressure sensor senses air pressure changes in the electronic atomizer and sends a signal to the control circuit which controls the electronic heating unit. The electronic heating unit heats a liquid to form an aerosol. A device to prevent the electronic atomizer from starting itself comprises a PTC self-recovery fuse 2, and a guide hood 1 whose inner wall 13, 14 forms a guiding passage comprising an inlet 11 and an outlet 12. The guiding passage becomes narrow from the inlet first to the center, and then is enlarged to the outlet. The PTC self-recovery fuse 2 is located at the narrowed part of the guiding passage and is in contact with the air.
