Temperature-controllable heating element, atomizer and electronic cigarette

Abstract

The invention discloses a temperature-controllable heating element. The temperature-controllable heating element comprises a conductive fixed seat, a drainage dielectric layer, a heating element, a first positive-pole contacting element, a positive ring and a temperature sensing device. The drainage dielectric layer is adhered to the inner wall of the conductive fixed seat. The heating element and the temperature sensing device are both arranged in the drainage dielectric layer. The temperature sensing device is close to the heating element or is arranged in the drainage dielectric layer close to a heating area of the heating element. The negative pole of the heating element and the positive-pole of the temperature sensing device are both electrically connected with the conductive fixed seat. The edge of the first positive-pole contacting element is inserted into one end of the conductive fixed seat in an insulating mode. The edge of the positive-pole ring is inserted to the outside of the conductive fixed seat in an insulating mode and is located in the outer side of one end of the conductive fixed seat. The positive-pole of the heating element is electrically connected with the first positive-pole contacting element. The positive-pole of the temperature sensing device is connected between the first positive-pole contacting element and the conductive fixed seat in a penetrated mode and is electrically connected with the positive-pole ring. The temperature-controllable heating element has the advantages that assembly is convenient, the temperature of the heating element can be monitored in real time, and taste experiment being influenced by overheating or dry burning is avoided.

Description

technical field [0001] The invention relates to the technology of electronic cigarettes, in particular to temperature-controllable heating components, atomizers and electronic cigarettes. Background technique [0002] Electronic cigarettes, also known as atomizers, electronic cigarettes, and virtual cigarettes, are mainly used to quit smoking and replace cigarettes. It has the appearance and taste similar to cigarettes. [0003] The current electronic cigarette is generally composed of a mouthpiece assembly, an atomizer and a battery assembly. The atomizer includes a heating assembly, a liquid storage assembly and a conductive assembly. Heated to form smoke, and then output through the mouthpiece. [0004] However, since the heating element directly heats the e-liquid after being powered on, it is prone to overheating or dry burning when the e-liquid is insufficient, resulting in damage to the heating element, and the scorching smoke under the action of high temperature af...
