Description

Technical Field

[0001] The present invention relates to the technical field of atomizer core structures, and in particular to a multi-layer composite atomizer core structure. Background Art

[0002] The nebulizer is used to atomize the test solution. The nebulizer is an important component of the atomization system. Its performance has a significant impact on the precision of the measurement and chemical interference. Therefore, the nebulizer is required to have stable spray, small and uniform droplets and high atomization efficiency. The nebulizer is widely used in the fields of electronic cigarettes, medical treatment and humidifiers. It can atomize liquids such as tobacco oil, liquid medicine and water. The atomizer core structure is one of the important components of the nebulizer and occupies an important position in the nebulizer.

[0003] Generally, the atomizer core of a traditional electronic cigarette atomizer uses an electrode to heat the atomizer at a high temperature to achieve atomization. However, since the atomizer tube usually adopts a single-pipe setting, when different flavors of e-liquid need to be atomized, the two e-liquids need to be mixed, thereby reducing the storage capacity of a single e-liquid, and the subsequent frequent addition of e-liquid. At the same time, the atomized e-liquid spray volume of the single-pipe design is small, so after the two e-liquids are mixed, the content of the single e-liquid in the mist volume is reduced, thereby affecting the actual use effect, which is very inconvenient. Moreover, the mixed e-liquid can only be added with new e-liquid after all the atomization is completed, thereby reducing the selectivity.

[0004] In summary, it is necessary to propose a multi-layer composite atomizer atomizing core structure to solve the above problems. Summary of the Invention
