A preparation method of an electronic cigarette mesh heating body

Abstract

The invention relates to a method for preparing a mesh heating body of an electronic cigarette. Firstly, resistance wires are used to weave a resistance wire mesh, and then electrodes are prepared on the resistance wire mesh; electrodes are prepared on the resistance wire mesh by covering the resistance wire mesh with conductive paste Formed; including the steps of pretreating the conductive paste, covering the conductive paste on the resistance screen, drying, curing, and cutting. Aiming at the shortcomings of the existing preparation process of the mesh heating element, the present invention provides a preparation method of the mesh heating element for electronic cigarettes with simple preparation process, good stability, low cost and suitable for industrial production.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a method for preparing a mesh heating body of an electronic cigarette. Background technique [0002] As a substitute for cigarettes, e-cigarettes instantly atomize a solution (e-liquid) with a specific flavor and effect through electronic heating to generate aerosol particles. The mainstream e-cigarette heating body on the market is mainly a spiral heating body made of electrothermal alloy wires. It has the advantages of simple production process and low cost and is widely used. However, it has its own disadvantages. The heating area of ​​the spiral structure heating body is relatively small. Small, the temperature in the middle area is high, the heat distribution is uneven, and the atomization effect of the e-liquid is not ideal, which is difficult to meet consumers' needs for a higher experience. With the development of electronic cigarette technology, the requirements for...

The mainstream e-cigarette heating body on the market is mainly a spiral heating body made of electrothermal alloy wires. It has the advantages of simple production process and low cost and is widely used. However, it has its own disadvantages. The heating area of ​​the spiral structure heating body is relatively small. Small, high temperature in the middle area, uneven heat distribution, unsatisfactory atomization effect of e-liquid, difficult to meet consumers' needs for higher experience

With the development of electronic cigarette technology, the requirements for the heating technology of electronic cigarettes are getting higher and higher, and a mesh heating body has appeared. The mesh heating body has the advantages of large heating area and uniform heat, and has been recognized by the electronic cigarette industry. However, The preparation process of the mesh heating body is immature, which limits its wide use

[0003] There are two main preparation techniques for the mesh heating body for electronic vaporizers on the market. One is to use two nickel wires to weld the metal mesh. The wire mesh is used as a heating mesh, but the higher the mesh number of the metal mesh, the smaller the diameter of the wire, the more lines per unit area, the more difficult the welding, the higher the production cost, and there are many false welding lines, but the wire mesh with a low mesh number cannot meet the requirements. Resistance requirements; the other uses metal parts riveted at both ends of the screen, the metal parts play a conductive role, the riveted mesh heating element will loosen due to the reduction of residual stress after a period of use, and there is a risk of poor contact
