[0006] The return pipe and suction pipe are inserted into the interior of the storage tank. A mixing tank is located inside the storage tank. Rubber sleeves are fitted onto the outer sides of both the suction pipe and the return pipe. A connecting sleeve is fitted onto the inner side of the two rubber sleeves. The connecting sleeve connects a rotating shaft fixed at one end to the inner side of the rubber sleeve. One end of the two connecting sleeves is joined together, and a connecting post is fitted onto the inner side of the connecting sleeve. Stainless steel springs are fixed at both ends of the connecting post. A pressure reducing valve is installed at the rear end of the paint pump housing. An air inlet for compressed air is located at the rear end of the pressure reducing valve. A gas flow meter is located at the right end of the pressure reducing valve.
[0007] Preferably, the paint pump housing is supported by a bracket fixed at the lower end.
[0008] Preferably, a stirrer and a viscosity sensor are installed inside the mixing tank, the mixing tank is fed through the discharge port at the upper end, and a discharge port is provided on the inner end face of the mixing tank.
[0009] Preferably, the air inlet is connected to an air source, and the air pressure is regulated by the pressure reducing valve to provide the required air source for the bubble atomizing nozzle.
[0010] Preferably, the paint pump housing absorbs paint from inside the storage tank through a suction pipe and an inlet suction cup, and the paint inside the storage tank originates from the mixing tank.
[0011] Preferably, the bubble atomizing nozzle is connected to the discharge valve via a connecting pipe, and the paint pump housing is provided with two discharge valves, both of which can be connected to the connecting pipe.

[0014] Compared with the prior art, the present invention provides an automatic batching aerosol spraying system, which has the following beneficial effects:
[0015] 1. Compressed air provides a stable air source to the bubble atomizing nozzle through a pressure reducing valve and an air flow meter. For different working conditions, a viscosity sensor is used to measure the viscosity of the paint in the mixing tank. The pre-mixed paint and solvent are automatically injected into the mixing tank and stirred evenly by the agitator in the mixing tank. A high-precision paint pump housing, through a pressure regulating valve and a liquid flow meter, stably and continuously delivers a fixed amount of paint to the bubble atomizing nozzle per unit time. A storage tank is installed after the paint pump housing. When the spraying operation is paused, it will automatically switch to a return pump to keep the entire system circulating, ensuring that the powder paint does not settle and ensuring its properties are stable. The specially designed bubble atomizing nozzle ensures that the gas atomizes the paint and sprays it evenly to meet the spraying process requirements. The entire system needs to adopt a specific connection structure to reduce the impact of gravity on the paint.
[0016] 2. The return pipe and the suction pipe are respectively fitted inside the two rubber sleeves. When in use, the pipes will move, causing the rubber sleeves to rotate around the rotating shaft. When subjected to external force, they will move outward through the connecting post. The elastic force of the stainless steel spring will cause the return pipe and the suction pipe to return to their original positions after the external force disappears. This can prevent the return pipe and the suction pipe from getting tangled together. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] The utility model provides, for example Figure 1-4An automatic aerosol spraying system is shown, comprising a paint pump housing 1 and a storage tank 11. A stainless steel buffer cup 5 is installed at the upper end of the paint pump housing 1. A pump body is installed inside the paint pump housing 1. A discharge valve 6 is installed at the upper front end of the paint pump housing 1, with its inner side connected to the pump body. A connecting pipe 13 is sleeved on the outer side of the discharge valve 6. A bubble atomizing nozzle 14 for spraying is installed at the other end of the connecting pipe 13. A return valve 7 is installed at the upper front end of the paint pump housing 1, with a return pipe 8 sleeved on its outer side. A suction pipe 9 for drawing in paint is installed at the lower front end of the paint pump housing 1, with an inlet suction cup 10 installed at the other end of the suction pipe 9. The return pipe 8... The suction pipe 9 is inserted into the interior of the storage tank 11. A batching barrel 20 is installed inside the storage tank 11. Rubber sleeves 15 are fitted onto the outer sides of the suction pipe 9 and the return pipe 8. A sleeve 16 is fitted onto the inner side of the two rubber sleeves 15. The sleeve 16 fits the rotating shaft 19, which is fixed at one end, into the interior of the rubber sleeves 15. One end of the two sleeves 16 is joined together. A connecting column 17 is fitted into the interior of the sleeve 16. Stainless steel springs 18 are fixed at both ends of the connecting column 17. A pressure reducing valve 4 is installed at the rear end of the paint pump housing 1. An air inlet 3 for connecting compressed air is installed at the rear end of the pressure reducing valve 4. A gas flow meter 2 is installed at the right end of the pressure reducing valve 4.
[0026] After the system starts, the paint pump draws paint from the storage tank 11 through the suction pipe 9 and the inlet suction cup 10. The system's air source enters through the air inlet 3 and the air pressure is regulated by the pressure reducing valve 4 to ensure that the gas pressure is suitable for the spraying requirements. The paint output from the paint pump may have pressure fluctuations. In order to ensure the stability of the paint flow, the paint will pass through the stainless steel buffer cup 5. The stainless steel buffer cup 5 absorbs pressure pulsations to ensure that the paint flow is smooth. The paint and gas are mixed at the bubble atomizing nozzle 14. The gas atomizes the paint into fine particles through high-speed flow, forming a uniform spraying effect. The atomized paint is sprayed onto the target surface to complete the spraying operation.
[0027] like Figure 1 and Figure 2 As shown, the paint pump housing 1 is supported by a bracket 12 fixed at the lower end. An agitator and a viscosity sensor are installed inside the mixing tank 20. The mixing tank 20 is fed through the discharge port at the upper end. A discharge port is provided at the inner end face of the mixing tank 20. The air inlet 3 is connected to an air source, and the air pressure is regulated by a pressure reducing valve 4 to provide the required air source for the bubble atomizing nozzle 14. The paint pump housing 1 absorbs the paint inside the storage tank 11 through the suction pipe 9 and the inlet suction cup 10. The paint inside the storage tank 11 comes from the mixing tank 20.
[0028] Compressed air provides a stable air source to the bubble atomizing nozzle 14 through the pressure reducing valve 4 and the air flow meter. For different working conditions, a viscosity sensor is used to measure the viscosity of the paint in the mixing tank 20. The pre-mixed paint and solvent are automatically injected into the mixing tank 20 and stirred evenly by the agitator in the mixing tank 20. A high-precision paint pump housing 1, through a pressure regulating valve and a liquid flow meter, stably and continuously delivers a fixed amount of paint to the bubble atomizing nozzle 14 per unit time. A storage tank 11 is installed after the paint pump housing 1. When the spraying operation is paused, it will automatically switch to the return pump to keep the entire system circulating, ensuring that the powder paint does not settle and ensuring its properties are stable. The specially designed bubble atomizing nozzle 14 ensures that the gas atomizes the paint and sprays it out evenly, meeting the requirements of the spraying process.
[0029] like Figure 2 and Figure 3 As shown, the bubble atomizing nozzle 14 is connected to the discharge valve 6 through the connecting pipe 13. The paint pump housing 1 is provided with two discharge valves 6, both of which can be connected to the connecting pipe 13. The bubble atomizing nozzle 14 atomizes and sprays the paint sucked in by the inlet suction cup 10. The return pipe 8 allows part of the paint to flow back into the interior of the storage tank 11. The return pipe 8 and the suction pipe 9 are both sleeved inside the rubber sleeve pipe 15. The two rubber sleeve pipes 15 are connected by a connecting post 17 and a stainless steel spring 18 sleeved inside the sleeve cylinder 16. The other end of the stainless steel spring 18 is fixed to the inner wall of the sleeve cylinder 16. When the return pipe 8 and the suction pipe 9 move, the rubber sleeve pipe 15 rotates around the rotating shaft 19 as the center axis. When the rubber sleeve pipe 15 is stretched, it moves through the connecting post 17.
[0030] The return pipe 8 and the suction pipe 9 are respectively fitted inside the two rubber sleeve pipes 15. When the return pipe 8 and the suction pipe 9 are in use, the pipes will move, causing the rubber sleeve pipe 15 to rotate around the rotating shaft 19. When subjected to external force, they will move outward through the connecting column 17. The elastic force of the stainless steel spring 18 will cause the return pipe 8 and the suction pipe 9 to return to their original positions after the external force disappears.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
