Microporous ceramic heater for electronic cigarettes and preparation method of heater

Abstract

The invention relates to the technical field of electronic cigarettes, in particular to a microporous ceramic heater for electronic cigarettes and a preparation method of the heater. The microporous ceramic heater comprises a ceramic carrier and a heating film arranged on the ceramic carrier, wherein the ceramic carrier is provided with a plurality of curved through holes running through the ceramic carrier; cigarette oil of an external electronic cigarette permeates into the curved through holes; and the heating film is used for heating the ceramic carrier so that the cigarette oil in the curved through holes is atomized and leaks out. The preparation method of the microporous ceramic heater is simple and efficient, operation and control are convenient, the product quality is stable, andindustrial production is facilitated; the ceramic carrier has the advantages that the strength is high, powder is unlikely to shed, and no peculiar smell is generated during use; the prepared microporous ceramic heater is resistant to dry burning, the bonding strength between the heating film and a ceramic body is high, there is no gap between a heating film circuit and the ceramic body after long-term use, and smoke leakage cannot happen.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, and in particular discloses a microporous ceramic heater for electronic cigarettes. Background technique [0002] E-cigarette is a low-voltage micro-electronic atomization escape device, which converts tobacco-flavored e-liquid into smoke through heating and atomization for use by smokers; the key component is the electric heating atomization escaper, which is also It is called atomization escape core. At present, there are many kinds of atomization escape cores in electronic cigarettes. Electric heating atomization escape cores are the most widely used in the electronic cigarette industry. [0003] The main structure of the electrothermal atomization escape core in the electronic cigarette industry is composed of an oil-conducting carrier, a heating element, a bracket and a shell. After the heating element is energized, the oil-conducting carrier is heated to generate aerosol. [...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the oil-conducting carrier of the atomization escape core is made of fiber cotton, which is suitable for use below 180°C, while the atomization escape temperature of e-liquid in the electronic cigarette industry is 170-250°C, the best The atomization release temperature is 220°C, especially for heavy smoke electronic cigarettes, its normal atomization release temperature needs to be above 220°C; limited by the use temperature, fiber cotton is used as the atomization release core of the oil-conducting carrier , in addition to being limited by the operating temperature, it cannot be dry-burned. If the temperature is higher than 180°C or dry-burned, the fiber cotton will have an odor or burn out the atomized escape core. If the temperature is higher than 190°C or dry-burned, the fiber cotton will Cotton decomposes, and the decomposed products contain many substances that are harmful to the human body, endangering the health of smokers, and are not environmentally friendly.
