The mobile multi-functional spraying device usually has a compact design and an easy-to-operate control system, enabling it to be quickly deployed and operated in various environments, such as construction sites, fire scenes, large equipment cleaning sites, etc. In addition, these devices often have multiple spraying modes and working pressure adjustment functions to adapt to different operation requirements and improve work efficiency and spraying effect.

[0003] Currently, when a mobile multi-functional spraying device extinguishes a fire, it generally sprays after mixing water and a medicament for fire extinguishing treatment. By mixing the medicament and water, the efficiency of fire extinguishing treatment is improved. However, when the mixing ratio of the medicament and water is inappropriate, when there is more medicament mixed, the use cost is increased, and when there is less medicament mixed, the efficiency of extinguishing the fire is affected.

[0022] The spraying mechanism includes a first pneumatic infusion pump 2 fixedly installed inside the outer shell assembly 14. A first connecting water pipe is installed between the first pneumatic infusion pump 2 and the water storage tank 1. Two high-pressure gas cylinders 3 are installed inside the outer shell assembly 14. A flow proportioning valve 5 is installed inside the outer shell assembly 14. An acceleration switch 6 is installed inside the outer shell assembly 14. An air pipe is installed at the air outlet end of the high-pressure gas cylinder 3. A connecting pipe is installed between the power switch 4 and the acceleration switch 6. The two air pipes are fixedly connected to the connecting pipe. A second pneumatic infusion pump 7 is installed inside the outer shell assembly 14. A first adjusting pipe is installed on the left side of the flow proportioning valve 5. A second adjusting pipe is installed at the bottom of the flow proportioning valve 5. One end of the first adjusting pipe away from the flow proportioning valve 5 is fixedly connected to the water inlet end of the first pneumatic infusion pump 2. One end of the second adjusting pipe away from the flow proportioning valve 5 is fixedly connected to the water outlet end of the second pneumatic infusion pump 7. A second connecting water pipe is installed between the water inlet end of the second pneumatic infusion pump 7 and the chemical agent tank 12.

[0023] A flow pipe is installed between the acceleration switch 6 and the liquid outlet assembly 9. A check device 8 is provided in the flow pipeline to prevent the mixed liquid from flowing into the air circuit. The liquid outlet end of the first pneumatic infusion pump 2 is fixedly installed with a liquid outlet assembly 9. One end of the liquid outlet assembly 9 away from the first pneumatic infusion pump 2 is fixedly installed with a water hose 10. One end of the water hose 10 away from the liquid outlet assembly 9 is fixedly installed with a spray gun 11. A partition is provided between the water storage tank 1 and the medicine tank 12, and the water storage tank 1 and the medicine tank 12 are not connected. The bottom of the outer shell assembly 14 is fixedly installed with a base 13, and a water hose storage box 15 is installed inside the outer shell assembly 14.

[0024] In this embodiment, a partition is provided between the water storage tank 1 and the medicine tank 12, and the water storage tank 1 and the medicine tank 12 are not connected.

[0025] In this embodiment, the water hose storage box 15 is used to store and retrieve the water hose 10 and the water gun 11.

[0026] In this embodiment, on the premise that the water, medicine and compressed air are fully filled, first take out the water hose 10 and the spray gun 11 and connect them to the quick socket of the water pipe at the water outlet of the device and straighten the water hose 10. Carry the spray gun 11 on the shoulder, and there should be no bending of the water hose 10. Then open the stop valve and the power switch 4 on the high-pressure gas cylinder 3 first. The high-pressure air fills the pipeline, and then open the operating lever on the spray gun 11 and spray it at the fire source. During the spraying process, adjust the flow rate proportional valve 5 and the acceleration switch 6 according to the on-site fire situation. After the spraying is completed, close the stop valve, the power switch 4, the acceleration switch 6 and the operating lever of the spray gun 11 on the high-pressure gas cylinder 3, and the high-pressure air and the remaining mixed liquid remaining inside the device should be discharged by opening the acceleration switch 6 and the operating lever of the spray gun 11 again. Then close the acceleration switch 6 and the operating lever of the spray gun 11 and retract the water hose 10 and the spray gun 11 and place them in the water hose storage box 15.

[0027] The working principle of the above embodiment is as follows:

[0028] When the mobile multi-functional spraying device is in use, the device can be moved to the location where it is needed through the base 13, the housing assembly 14 and the wheels. Compressed air is stored in the high-pressure gas cylinder 3. When the stop valve and the power switch 4 on the high-pressure gas cylinder 3 are opened, the high-pressure air enters the first pneumatic infusion pump 2 and the second pneumatic infusion pump 7 through the air path after being decompressed by the pressure reducer, so as to start the first pneumatic infusion pump 2 and the second pneumatic infusion pump 7, and the first pneumatic infusion pump 2 and the second pneumatic infusion pump 7 are respectively used to pump out the water and the medicament inside the water storage tank 1 and the medicament tank 12. The pumped-out medicament converges at the liquid inlet of the first pneumatic infusion pump 2 after passing through the second pneumatic infusion pump 7 and the flow proportion valve 5, and then flows through the first pneumatic infusion pump 2 and the liquid outlet assembly 9 and is fully mixed and foamed inside to form a fire extinguishing mixture, which is sprayed out through the water hose 10 by using the spray gun 11 for fire extinguishing. The water storage tank 1 and the medicament tank 12 are always in a non-pressure storage state, so as to ensure the safe and reliable operation of the water storage tank 1 and the medicament tank 12 in a high-temperature environment. Moreover, the water and the medicament are stored separately and not premixed in advance, which improves the storage time. During spraying, the acceleration switch 6 can be opened at the same time to directly let the high-pressure air in the bottle enter the pipeline of the liquid outlet assembly 9 to accelerate the inside of the liquid outlet assembly 9 to increase the spraying distance, and the check device 8 is used to prevent the mixed liquid from flowing back into the air pipeline. The flow proportion valve 5 can accurately control the flow rate of the medicament flowing through here. For different degrees of fire, the flow rate of the medicament can be adjusted by adjusting the flow proportion valve 5, so as to produce different proportions of the mixed liquid for fire extinguishing.
