[0002] Electronic cigarettes, also known as electronic cigarettes, electronic aerosols or electronic nicotine delivery systems, are electronic devices that simulate the smoking experience by heating liquids to produce steam, and the atomizer is the core component of electronic cigarettes. The atomizer is generally composed of a cartridge and a host. Driven by the host, the cartridge heats the oil to produce smoke for the user to inhale. At present, some hosts adopt a split structure, that is, the host consists of a detachable upper shell and a lower shell, and the upper shell only serves as a wrapping function without other functional functions. All functional structures are integrated in the lower shell, which is not easy to maintain. In addition, according to the different usage needs of each user, traditional atomizers generally adjust the airflow by adding an air-adjusting structure, such as gear rotation air-adjusting or adding an air-adjusting ring. However, these two airflow adjustment methods require the addition of other components, which are complex in structure, inconvenient to operate, and have poor sealing, which in turn affects the accuracy of air adjustment and reduces the user experience.
