Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirrer with an adjustable sealing cover. Background Art

[0002] In the aerosol industry, the content of aerosol is the key to ensuring the quality of aerosol. Aerosols usually contain suspended matter (such as drug particles, pigments, etc.), solvents and propellants (such as liquefied petroleum gas, dimethyl ether, etc.). If these components are not dispersed and dissolved well, they may stratify or precipitate in a static state, resulting in uneven concentration, poor atomization and even nozzle clogging during spraying. The agitator can effectively disperse the suspended matter in the solvent to ensure uniform concentration and good atomization effect during spraying.

[0003] In the existing aerosol material mixing process, an open stirring device is mostly used, which easily leads to the mixing of external dust, oil, water vapor and other impurities, and the volatile substances in the material are also easy to overflow, which seriously affects the quality of the aerosol. At the same time, the volatilization of the solvent in the material will also affect the environment and the health of the operator and cause production losses. In addition, the existing stirring device generally does not have the cleaning function and the function of monitoring the temperature and humidity of the surrounding environment. The user needs to manually clean the stirring tank used in conjunction with the stirring device, which is inconvenient to use; and the lack of temperature and humidity detection may indirectly cause safety hazards caused by the failure to eliminate static electricity in time.

[0004] Therefore, it is urgent to propose a solution to solve at least one of the problems existing in the existing stirring device. Utility Model Content
