Abstract: A vaporizer device includes a vaporization unit for heating the smoke oil to generate an aerosol, a battery for supplying power to the vaporization unit, a housing connected to one end of the vaporization unit and accommodating the battery and a mouthpiece connected to the other end of the vaporization unit and used for inhaling the aerosol generated by the vaporization unit. The vaporizer device further includes a rotating part provided on the outside of the housing to rotate relative to the housing. By turning the rotating part, a user can relieve anxiety and stress. This indicates that the vaporizer device has an improved pressure relief effect. An annular knob is slidable toward a printed circuit board (PCB), so that a light-emitting diode (LED) lamp is controlled to change color.
