Liquid tobacco tar type electronic cigarette heater and electronic cigarette

Abstract

The invention discloses a liquid tobacco tar type electronic cigarette heater and an electronic cigarette. The heater comprises a thick film heating layer and a first porous ceramic layer which fits one side face of the thick film heating layer, wherein the thick film heating layer comprises a substrate, a heating circuit layer which is arranged on a first surface of the substrate, a conductive layer which is connected with the heating circuit layer and a guiding wire which is connected with the conductive layer, and the first porous ceramic layer fits a second surface of the substrate. The heater has the advantages that when the thick film heating layer is electrified, the whole substrate can be heated through the heating circuit layer, liquid tobacco tar is attracted by the first porousceramic layer to reach the contacting face of the first porous ceramic layer and the substrate to absorb heat and for atomized steam, the thermal contacting area is larger, the heating efficiency andheating responding speed are improved, no harmful substance is generated by the direct contact of the liquid tobacco tar and the substrate, which facilitates the health of a user.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of electronic cigarettes, in particular to a liquid e-liquid type electronic cigarette heater and electronic cigarette. Background technique [0002] In recent years, as people’s awareness of the dangers of traditional cigarettes has increased, the market capacity of e-cigarette products has further expanded. Among them, e-cigarettes are electronic products that imitate cigarettes and have the same appearance, smoke, taste and feel as cigarettes. Cigarette is a product that users can smoke after turning nicotine into steam by heating and atomizing. The fundamental difference between it and cigarettes is "heating and not burning." [0003] The core component of e-cigarettes is e-cigarette heaters. At present, most liquid e-cigarette heaters on the market use oil-absorbing cotton to wind the resistance wire (such as figure 1 Shown). However, by heating the heating wire, the thermal contact ...

AI Technical Summary

Problems solved by technology

However, the thermal contact area is small due to the heating of the electric heating wire. In order to achieve the target temperature, the heating wire needs a higher temperature to realize the temperature difference exchange, resulting in low heating efficiency and slow heating response speed.

In addition, the resistance wire that is in direct contact with the liquid e-liquid is made of nickel-chromium, and long-term high temperature is prone to produce heavy metals, which is harmful to human health
