Abstract

The invention discloses a porous ceramic heating element used for atomizing tobacco tar of an electronic cigarette. The porous ceramic heating element comprises a porous ceramic substrate, a resistivelayer jointed with the surface of the porous ceramic substrate, and a lead electrically connected with the resistive layer by means of an electrode, wherein the surface, jointed with the porous ceramic substrate, of the resistive layer is provided with a first protective layer for isolating tobacco tar. According to the heating element provided by the invention, the resistive layer is not directly contacted with the tobacco tar, so the the corrosion effect of the tobacco tar on the resistive layer is avoided, and the service life of the resistive layer is accordingly prolonged. The inventionalso provides a manufacturing method of the porous ceramic heating element; a first protective layer and the resistive layer are printed on the surface of a whole piece of porous ceramics, and the porous ceramics is then cut, so that a plurality of independent ceramic heating elements are obtained; therefore, the batch processing of heating parts of the porous ceramic heating element is realized,and the production efficiency of the porous ceramic heating element is increased to a certain extent.

Description

technical field

[0001] The invention relates to the technical field of heating elements of e-liquid type electronic cigarettes, in particular to a porous ceramic heating element and a manufacturing method thereof. Background technique

[0002] In the e-cigarette industry, the e-liquid-type e-cigarette technology is relatively mature, well developed, and has a wider market for use. In the existing e-liquid type electronic cigarette, the heating device includes a ceramic substrate and a heating component. After the power supply is connected, the heating component generates heat and atomizes the e-liquid heating. In recent years, some porous ceramic atomizing cores with different regulations and structures have appeared on the market, which have been initially recognized by users and the market.

[0003] However, the heating components heated with the e-liquid are susceptible to corrosion by the e-liquid under high temperature conditions, thereby affecting the effect of the he...
