Heating device for electronic cigarettes

Abstract

The invention discloses a heating device for electronic cigarettes, belonging to the field of electronic cigarettes, comprising a tube body, a heating body arranged on the outer circumference of the tube body, a positive electrode and a negative electrode connected to the heating body; the tube body The main body is in the shape of a hollow tube, and the heating element is formed by connecting a plurality of serpentine heating elements end to end in series. One end of the heating element is connected to the positive electrode, and the other end is connected to the negative electrode. The beneficial effect of this patent is: a heating element composed of a plurality of serpentine heating parts is arranged on the surface of the tube body, and the heat is generated through the resistance of the heating element and transferred to the inner side of the tube body, so that the oil fume in the tube body is quickly atomized to achieve purpose of heating.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a heating device for electronic cigarettes. Background technique [0002] There is an atomizer in the electronic cigarette, and the atomizer includes a heating device to heat and generate smoke. The existing heating device uses a heating wire to heat and atomize the e-liquid by heating the heating wire, but the disadvantage of using the heating wire to heat is , The heating contact area is small, and the heating is uneven. For example, the temperature of the part close to the heating wire is high, and the temperature of the part far away from the heating wire is low. Therefore, it is imperative to provide a heating device with a larger heating area and more uniform heating. [0003] For example, the invention patent with the notification number CN205305996U discloses a composite metal electronic cigarette heating element, which includes a tube body and a heating film, and the...
