[0002] Aerosol cans are a type of packaging equipment widely used in many fields, which are designed to store and release high-pressure gases or liquids. The structure and function of this container make it an indispensable part of modern industry, especially in the daily chemical, pharmaceutical and car care industries.

[0003] After searching, the application number is "202221551392.7", which provides an air pressure detection device for detecting the sealing of an aerosol can. The first spring is fixed on the inner top wall and the inner bottom wall of the shell. There are eight first springs in total, and every four are connected and fixed to a first clamp block. The two first clamp blocks correspond to each other. The elastic sealing airbag is placed in the shell. The outer surface of the elastic sealing airbag is connected to the air inlet pipe and the air outlet pipe. One end of the air inlet pipe and the air outlet pipe is respectively connected to the air inlet control valve and the air outlet control valve. When testing the aerosol can, the elastic sealing airbag can adapt to different pipe diameters because of its elasticity. The aerosol can passes through, and after the aerosol can passes through the elastic sealing airbag, the mouth of the aerosol can is aligned with the air flow hole, and the first clamp block can fix the head of the aerosol can. The diameters of the aerosol cans are different, so the first clamp block can compress the first spring according to the diameter size, and then open the air intake control valve to make the elastic sealing airbag start to expand and seal the inside of the shell, so as to facilitate the subsequent air pressure detection of the aerosol can. During the detection, the hydraulic rod is started to move the piston plate to compress the air in the cavity, so that the air passes through the air flow hole of the partition, and air pressure is applied to the aerosol can to perform air pressure detection.
