[0027] The working principle of the utility model is:

[0028] When the gas pressure in the aerosol bottle body increases, the gas will push the valve rod 4 to move upwards. At this time, the clamping block 5 on the valve rod 4 will slide along the outer surface of the compression spring 3 under the elastic force of the compression spring 3 and keep stable. Since the top end of the valve rod 4 extends above the shell 1, when the valve rod 4 moves upwards, it will open the channel inside the bottle body, so that the gas can be smoothly sprayed out. At the same time, the design of the built-in gasket 6 can ensure the sealing between the valve rod 4 and the shell 1, preventing gas leakage. When the gas pressure in the aerosol bottle body decreases, the elastic force of the compression spring 3 will push the valve rod 4 to move downwards, so that the channel is closed, thereby maintaining the stability of the pressure inside the bottle body.
