Embodiment 1

[0039] As long as there are three types of e-cigarette ceramic heaters: tubular, sheet, and needle-shaped, they are mainly made of alumina or zirconia ceramics, and high-temperature fired tungsten paste, platinum paste, gold paste, etc. are used as electrode materials, and the cost is relatively high. . Most of them use alumina, and tungsten is used as the electrode material. The main problem is that the thermal conductivity of alumina is high, and the heat diffuses quickly through the ceramic body during heating, which leads to an increase in the temperature of the rear end of the heating body, which not only causes serious heat loss but also causes Other components generate heat, so a flange ring with low thermal conductivity is required to resist heat, and the cost increases. Using zirconia, a low thermal conductivity material, can solve the problems of slow temperature rise, high power consumption, and high back-end temperature of alumina materials, but the matching heatin...

Abstract

The invention provides a ceramic heating body for an electronic cigarette. The ceramic heating body comprises a ceramic inner core and a ceramic substrate wound on the ceramic inner core; a heating circuit is arranged on a bonding surface of the ceramic substrate and the ceramic inner core; a heat conducting layer is arranged outside the ceramic substrate; the heat conductivity of the heat conducting layer is greater than that of the ceramic substrate; and the heat conducting layer is a silver layer, a silver-palladium layer or a silver-platinum layer, so that the ceramic inner core and the ceramic substrate are made of low-temperature sintering materials. The heat distribution of the surface of the ceramic heating body can be quickly balanced by attaching one heat conducting layer with the heat conductivity greater than that of the ceramic substrate outside the ceramic substrate, so that the temperature of the surface of the ceramic heating body is uniform; and meanwhile, the requirements on the heat conductivity of the ceramic substrate are reduced due to the existence of the heat conducting layer, so that the low-heat-conductivity material can be adopted, and the temperature ofa bonding wire region can be reduced.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a ceramic heating body for electronic cigarettes. Background technique [0002] Due to the advantages of low-temperature baking e-cigarettes such as non-combustion and no production of toxic substances such as carbon monoxide, it has been rapidly developed in the world in recent years; and the ceramic heating body is its core component, which determines the overall design and performance quality of e-cigarettes Level. At present, the electronic cigarette ceramic heaters on the market are divided into three categories: tubular, sheet, and needle-shaped according to their different shapes. They are mainly made of alumina or zirconia ceramics, combined with high-temperature fired tungsten paste, Platinum paste, gold paste, etc. are used as electrode materials. [0003] The early products were mainly made of alumina, but due to the high thermal conductivity of alumina...
