Abstract

The invention relates to an electronic cigarette heater. The electronic cigarette heater at least comprises a ceramic substrate (1), wherein the ceramic substrate (1) is composed of a zirconia toughened alumina (ZTA) ceramic substrate, a bottom insulating layer (2), an upper electrode layer (3), a lower electrode layer (4), a weldable layer (5) and a surface insulating layer (6), wherein the bottom insulating layer (2), the upper electrode layer (3),the lower electrode layer (4), the weldable layer (5) and the surface insulating layer (6) are sequentially printed on the surface of the ceramicsubstrate (1), and the upper electrode layer (3) is connected with the lower electrode layer (4); and the weldable layer (5) coincides with the lower electrode layer (4). The electronic cigarette heater has high strength and good thermal conductivity.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, and more specifically, the invention relates to an electronic cigarette heater. Background technique [0002] Existing electronic cigarette heaters generally print an insulating layer, a heating layer, etc. on the surface of a ceramic substrate. Therefore, the quality of the ceramic substrate determines the life of the electronic cigarette heater. The ceramic substrate of the general electronic cigarette heater is made of pure zirconia or pure alumina. The thermal conductivity of the pure zirconia substrate is not good, while the strength of the pure alumina substrate is not enough. [0003] For example, the application number: 201810385710.9 discloses a sheet-type electronic cigarette heater, which includes a protective anti-fouling layer. The protective anti-fouling layer includes: a metal substrate, and an insulating layer covering the surface of the metal substrate; The heatin...
