The working principle and the using process are as follows:

when the internal pressure of the aerosol can is increased to exceed the normal working pressure range due to the influence of the external environment, 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 elastic force of the supporting spring 13 to move towards the inside of the groove 12, and when the pressure exceeds a preset value, the piston plate 14 moves upwards to the position above 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 internal pressure of the can body is ensured not to be overloaded, and the situations such as explosion are avoided;

in the process of spraying the aerosol can, firstly, the second valve 22 is opened, then the operator presses the pressing block 7 downwards, the first valve 5 is opened in the process of pressing the pressing block 7 downwards, the effective gas in the can body 1 can be pushed out under the action of the internal air pressure, so that the spraying effect is realized, the inner side of the elastic airbag 11 is pressed through the guide pipe 19 connected with the pressing block 18 through the pressing plate 18 while the pressing block moves downwards, so that the gas in the elastic airbag 11 enters the shell 804 from the guide pipe 19, the annular channel 20 and the second channel 21, because the pipe diameter of the second channel 21 is small, the gas is discharged outwards from the interior of the elastic airbag 11 in the spraying process of pressing the pressing block 7, and the discharged gas enters the shell 804 and then enters the mixing nozzle 802 from each through hole 803, so that the discharged high-speed gas can be combined with high-pressure spraying, thereby further improving the spraying effect, ensuring the spraying and atomizing effect and improving the working efficiency; after one-time spraying is finished, along with the fact that the pressing block 7 restores to the original position under the rebounding effect of the return spring 6, the elastic air bag 11 also starts to restore to the original position under the self elastic effect, 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 influence of residual materials on the normal work of next spraying is avoided, and finally the second valve 22 is closed, so that one-time spraying can be finished.
