Preparation method of LTCC (Low Temperature Co-Fired Ceramic) heater for electronic cigarette

Abstract

The invention discloses a preparation method of an LTCC (Low Temperature Co-Fired Ceramic) heater for an electronic cigarette, and belongs to the field of electronic components. The preparation method comprises the following steps: firstly, preparing a porous ceramic material; secondly, preparing a conductor and a resistance material; then, processing and preparing a green body of the electronic cigarette ceramic heating body through an LTCC (Low Temperature Co-Fired Ceramic) process; and finally, preparing the electronic cigarette ceramic heating body through low-temperature co-firing. In the material, the sintering temperature is regulated and controlled by adopting the glass ceramic, the pore distribution and pore size of the porous ceramic are regulated and controlled by the pore-forming agent, and the stroke distance of tobacco tar is reduced by slotting, so that the porous ceramic and various conductor slurries are matched and co-fired in a multi-layer manner, and meanwhile, a proper amount of smoke is generated in the atomization process of the electronic cigarette, and the airflow is smooth; no scorched taste effect exists. The product reliability, the quality consistency and the stability are greatly improved, and meanwhile, the oil guide groove is introduced to greatly improve the atomization quality of the atomizer. The method is widely applied to the ceramic heating body for the electronic cigarette so as to realize the preparation of the novel ceramic heating body for the electronic cigarette.

Description

technical field [0001] The invention belongs to electronic products, and further relates to the field of electronic cigarettes, in particular, to a method for preparing an LTCC ceramic heater for electronic cigarettes. Background technique [0002] The structure of the ceramic heating element of the electronic cigarette is a heating element, which is powered by the battery to generate heat, so that the smoke oil next to it volatilizes and forms smoke, so that the effect of "swallowing clouds and fog" can be achieved when people smoke. Its quality mainly depends on the materials used, heating wire and its manufacturing process. The preparation process of the traditional electronic cigarette porous ceramic substrate is similar to the preparation process of general ceramic components. At present, the key points of the ceramic heating element are the ceramic strength and the printing of the circuit. The preparation process of the electronic cigarette ceramic heating element is t...

Problems solved by technology

[0004] The technical problems to be solved by the present invention are: in the traditional technology, the reliability of the adhesion between the resistor and the electrode and the porous ceramic substrate is low, the quality consistency is poor, and the viscosity of the e-liquid affects the atomization amount of the product

It is used to solve the problems of the existing electronic cigarette ceramic heating element due to the poor fluidity of high-viscosity e-liquid, resulting in small smoke volume, poor taste, poor reliability of post-fired electrodes and resistors, low life, poor consistency, and low production efficiency.
