Porous ceramic electronic cigarette heater and preparation method thereof and electronic cigarette

Abstract

The invention discloses a porous ceramic electronic cigarette heater. The porous ceramic electronic cigarette heater comprises a porous ceramic carrier, a heating layer and a power supply, wherein theporous ceramic carrier is used for attracting tobacco tar, the heating layer covers the upper surface of the porous ceramic carrier and is used for heating the tobacco tar, particularly, the heatinglayer is formed by sintering resistance paste, the heating layer comprises a permeable heating layer permeating into the porous ceramic carrier, and the power supply is connected to the heating layerthrough a lead and used for supplying power to the heating layer. The provided porous ceramic electronic cigarette heater has the advantages that heating is quick, the power density is high, the thermal capacity is low, the small-scale integration is easy, the impact resistance is strong, the porous ceramic electronic cigarette heater is low-temperature and environmentally-friendly, and the heavymetal pollution does not exist, and the problems are solved that a traditional electronic cigarette heater has low heat efficiency, easy oxidation, brittle failure, change of a resistance value (power) and the like. The invention further provides a preparation method of the porous ceramic electronic cigarette heater and an electronic cigarette, and the preparation method of the porous ceramic electronic cigarette heater and the electronic cigarette have the above advantages.

Description

technical field [0001] The present application relates to the field of electronic cigarettes, in particular to a porous ceramic electronic cigarette heater, a preparation method thereof, and an electronic cigarette. Background technique [0002] E-cigarettes are electronic products that mimic cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that users can smoke after turning the e-liquid into vapor by means of heating and atomization. The fundamental difference between it and cigarettes is "heating without burning". [0003] At present, most e-liquid e-cigarette heaters on the market use oil-absorbing cotton to heat the e-cig oil by wrapping resistance wires outside, such as figure 1 As shown, the helix of the helical resistance wire is provided with a rope-shaped liquid-conducting cotton, and through the penetration of the liquid-conducting cotton, the e-cigarette liquid is introduced into the resistance wire of the atomizing core to ...

AI Technical Summary

Problems solved by technology

[0004] However, the thermal contact area of ​​the resistance wire is small. In order to achieve the target temperature, a higher temperature is required to realize the temperature difference heat transfer, so the heating efficiency is lower and the heating response speed is also slower.

At the same time, because the resistance wire is exposed to the air at high temperature for a long time, there are problems such as easy oxidation, brittle fracture, and changes in resistance value (power)
