Tubular electronic cigarette heater, preparing method thereof and electronic cigarette

Abstract

The invention discloses a tubular electronic cigarette heater which comprises a metal tube, an insulating layer wrapping the outer surface of the metal tube, a heating layer for heating the metal tube, and a protection layer covering the heating layer. The heating layer is led out of the protection layer through a lead. According to the tubular electronic cigarette heater, by arranging the insulating layer on the outer surface of the metal pipe and arranging the thick-film circuit heating layer formed by sintering resistance paste on the insulating layer, since a thick-film circuit is quite low in overall thickness and is attached to the insulating layer through high-temperature sintering, the thick-film circuit heating layer can be regarded as one part of the tube wall of the tubular electronic cigarette heater, the tubular electronic cigarette heater has the advantages of being rapid in heating, extremely high in power density and the like and is high in electro-thermal conversion efficiency, and energy consumption is reduced. The invention further provides a preparing method of the tubular electronic cigarette heater and an electronic cigarette with the same advantages.

Description

technical field [0001] The present application relates to the field of electronic cigarettes, in particular to a tubular electronic cigarette heater, a preparation method thereof, and an electronic cigarette. Background technique [0002] With the improvement of people's awareness of the dangers of traditional cigarettes, the voice of tobacco control is also increasing. In addition, with the rapid development of electronic technology in recent years, electronic cigarettes have emerged as the times require, and low-temperature baking electronic cigarettes have gradually become a new trend. The core component of the electronic cigarette is the electronic cigarette heater, such as figure 1 As shown, the heaters of tubular e-cigarette products currently on the market mostly use a structure in which a metal tube is wrapped around a heating wire, and the pod or core is placed in the tube to heat it. However, in order to prevent the heating wire from short-circuiting The surface o...

Problems solved by technology

The core component of the electronic cigarette is the electronic cigarette heater, such as figure 1 As shown, the heaters of tubular e-cigarette products currently on the market mostly use a structure in which a metal tube is wrapped around a heating wire, and the pod or core is placed in the tube to heat it. However, in order to prevent the heating wire from short-circuiting , the surface of the metal tube and the heating wire must be covered with a layer of insulating material that can withstand a certain temperature, and the thermal contact area is relatively small when heated by the heating wire, resulting in low heating efficiency of the heater and poor heating response. The speed is also slow, increasing energy consumption, and there are defects such as difficult temperature acquisition and control, power attenuation, etc.
