Chip type electronic cigarette heater, preparation method thereof and electronic cigarette

Abstract

The invention discloses a chip type electronic cigarette heater which comprises a protection anti-fouling layer. The protection anti-fouling layer comprises a metal substrate, an insulating layer covering the surface of the metal substrate, a heating layer which covers the insulating layer and is used for heating the metal substrate, and a conductor layer which covers the insulating layer and is connected with the heating layer and used for conducting the heating layer. The substrate is set as the metal substrate, and the problem that the service life of an instrument is affected due to the characteristic that ceramics is hard and crisp is avoided; the metal substrate has the good thermal conductivity, the heat conducting speed is high, the heating efficiency of the chip type electronic cigarette heater is improved, and the heating response speed of the chip type electronic cigarette heater is increased; meanwhile, by arranging the insulating layer on the surface of the metal substrate, the thick film circuit heating layer formed by sintering resistance paste is arranged on the insulating layer, the advantages of high heating speed and high power density are achieved, and energy consumption is lowered; the invention further provides a preparation method of the chip type electronic cigarette heater and an electronic cigarette having the advantages.

Description

technical field [0001] The present application relates to the field of electronic cigarettes, in particular to a sheet-type 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 sheet-shaped electronic cigarette products currently on the market mostly use ceramic sheets as substrates, and heat-generating circuits are made on the surface of ceramic substrates. The method of use is to insert them into cigarette cores or cartridges for heatin...

AI Technical Summary

Problems solved by technology

[0003] However, due to the low thermal conductivity of ceramic materials, the ceramic substrate will not easily conduct heat, resulting in low heating efficiency and slow heating response speed

At the same time, because ceramics are hard and brittle, once they are subjected to external forces during use, they are prone to brittle fracture, which will affect the service life of the appliance.
