Abstract: A portable atomizing apparatus according to the present invention includes a battery case, an atomizing device, a body case, a control unit, and a suction adjustment. The battery case receives a battery, and the atomizing device includes a heating member electrically connected to the battery for generating heat to atomize a source material. The body case is connected between the battery case and the atomizing device. Besides, the control unit is mounted inside the body case, electrically connected to the battery and to the heating member, so that the control unit receives an electrical power from the battery to control the output signal delivered to the heating member. Also, the suction adjustment opens or closes an air inlet of the atomizing apparatus so as to adjust the amount of air entering the atomizing apparatus.
