Description

Technical Field

[0001] The utility model relates to the technical field of atomizer core structure equipment, in particular to an atomizer core structure of a MEMS silicon-based heating plate. Background Art

[0002] As the core component of liquid atomization products, the heating atomization core is used to heat the liquid and turn it into a mist aerosol form. Liquid heating atomization cores mainly include cotton-wrapped atomization cores and porous ceramic atomization cores. In the cotton-wrapped atomization core, the metal heating wire and the cotton core are in direct contact. At high temperatures, the metal components in the heating wire and the debris of the cotton core material may be carried by the aerosol formed by atomization and inhaled by the user, causing potential health hazards. At the same time, the cotton core is in non-uniform contact with the metal heating wire, the heating is uneven, and the high-temperature carbonization will also cause the resistance of the heating wire to change, which in turn causes the temperature of the heating wire to change, making the atomization uniformity, stability, and consistency poor. The porous ceramic atomization core consists of two parts: porous ceramic and heating electrode. The porous ceramic is sintered at high temperature to form a bowl-shaped structure. The heating film is designed to be attached to the ceramic surface in a specific shape. During operation, the heating film heats the liquid to form mist by uniform heating, which is emitted by the ceramic micropores.

[0003] The application number is CN202122589150.9, which discloses an atomizer core structure based on a MEMS silicon-based heating plate, including: a silicon-based heating plate and a porous ceramic core, the silicon-based heating plate includes a heating wire and a silicon-based substrate, the heating wire is made on the surface of the silicon-based substrate, the silicon-based substrate is provided with array-arranged atomization micropores, the silicon-based substrate is fixedly mounted on the porous ceramic core, and the atomization micropores are connected to the porous ceramic core. Compared with the prior art, the utility model avoids leakage of the atomizer core, reduces processing difficulty, improves the yield rate, increases the atomization heating area of ​​the atomizer core, improves temperature uniformity, increases the amount of mist, and reduces dry burning.

[0004] The atomizer core structure based on a MEMS silicon-based heating plate disclosed in the above document has the following defects: when the atomizer core structure needs to be installed somewhere for use, the outside of the structure needs to be protected, otherwise the atomizer core will be damaged by external force, shortening the service life of the atomizer core.

[0005] It can be seen from this that the existing atomizer core structure does not have the function of preventing the outer part of the atomizer core from collision. It is necessary to improve the existing deficiencies and provide a function that can prevent the outer part of the atomizer core from collision. Utility Model Content
