Working principle and using flow:

when the internal pressure of the aerosol can is influenced by the external environment and is increased to exceed the normal working pressure range, the internal pressure of the aerosol can acts on the piston plate 14, the increased air pressure pushes the piston plate 14 to overcome the elasticity of the supporting spring 13 and move towards the inside of the groove 12, and when the pressure exceeds a preset value, the piston plate 14 moves upwards to the upper part of the air inlet 16, so that part of air in the can body 1 enters the elastic air bag 11 from the first channel 17, the pressure in the can body can be relieved, the pressure in the can body can not be overloaded, and the conditions such as explosion and the like are avoided;

in the aerosol can spraying process, first, the second valve 22 is opened, then the worker presses the pressing block 7 downwards, the first valve 5 is opened in the pressing block 7 pressing process, the effective gas in the can body 1 can be pushed out under the action of the internal gas pressure, so that the spraying effect is realized, while the pressing block moves downwards, the inner side of the elastic air bag 11 is extruded through the guide pipe 19 connected with the pressing block, the gas in the elastic air bag 11 enters the shell 804 from the guide pipe 19, the annular channel 20 and the second channel 21, and the pipe diameter of the second channel 21 is smaller, so that the gas is always discharged outwards in the spraying process of pressing block 7 pressing, and the discharged gas enters the shell 804 from each through hole 803, so that the discharged high-speed gas is combined with high-pressure spraying, the spraying effect is further improved, the spraying atomizing effect is ensured, and the working efficiency is improved; after the primary spraying is finished, along with the return of the pressing block 7 under the rebound action of the return spring 6, the elastic air bag 11 also starts to recover under the self elastic action, negative pressure can be generated inside the elastic air bag 11, air is sucked from the mixing nozzle 802 and the through hole 803 through the guide pipe 19, the annular channel 20 and the second channel 21, meanwhile, residual materials inside the mixing nozzle 802 can be sucked, the normal work of the next spraying is prevented from being influenced by the residual materials, and finally the second valve 22 is closed, so that the primary spraying can be finished.
