Problems solved by technology

Traditional manufacturing technologies such as turning, milling, planing, grinding, and mold forming can also prepare the support body, conductive liquid, and atomizing body separately and then assemble them to obtain the above-mentioned atomizing core with multi-functional areas; but the obtained atomizing core is not Complete finished product, the parts are loosely combined, and the problem of product cracking is serious; the service life of the atomizing core is short, and it is difficult to meet the requirements of the structural strength, atomizing performance and oil-conducting ability of the atomizing core.
At the same time, since the traditional injection and dry pressing molding methods need to use molds for molding, it is impossible to prepare embryonic body shapes with more complex shapes, which further hinders the possibility of optimizing the comprehensive performance of the atomizing core.

Embodiment 1

[0034] The forming method of the atomizing core with multi-functional area in this embodiment is prepared by stacking forming method, such as figure 1 As shown, three nozzles are used to spray raw materials with different compositions to spray the raw materials of the support area 110, the oil guide area 120 and the atomization area 130 respectively, and the functional areas of the atomization core are formed layer by layer, and finally stacked layer by layer to form a complete body. The method of 3D atomizing core is as follows: figure 2 As shown, calcining and sintering can obtain the finished atomizing core.

[0035] The raw materials of the supporting area (110) are: 10-75 parts by weight of a mixture of alumina powder and zirconia powder; 5-50 parts by weight of a mixture of polymethyl methacrylate and sucrose, wherein the mass ratio of polymethyl methacrylate to sucrose is It is 1: (0.5-1.5); The mixture of paraffin wax, low-temperature glass and dibutyl phthalate is 0...

Embodiment 2

[0045] The molding method of this embodiment is prepared using a solidification molding method, such as image 3 As shown, the laser irradiation head is used to irradiate the powdered raw material, so that the binder in the raw material melts and other materials in the raw material are bonded together to form a complete 3D atomizing core layer by layer. The steps of the curing molding method are as follows: the formed layer contains functional area materials at the same time, such as the support area, the atomization area and the powder material of the oil guide area. Then remove the powder material in the oil guide area, and then lay the powder material in the atomization area for molding; then lay the powder material in the support area for molding, forming layer by layer, and finally forming a green embryo with a complete and integrated 3D atomizing core. The composition of the powder material in the support area, the atomization area and the oil guide area is as follows: ...

Description

technical field [0001] The invention belongs to the technical field of tobacco atomization, and in particular relates to a 3D forming method of an atomization core with a multifunctional area. Background technique [0002] The atomization core of the electronic cigarette needs to take into account the main functions of atomization, oil conduction and support, that is, the atomization core needs to meet the requirements of strong oil conduction, high thermal conductivity of atomization and stability of support function. Most of the structure of the atomization area of ​​electronic cigarettes currently on the market is an atomization chip with uniform material; for a single atomization core with uniform material, the three functions of oil guide, atomization and support are composed of the same material. Complete, without the division of functional areas, these three functional requirements are mutually constrained, the strength of the ceramic structure with strong oil conduct...
