[0002] In the field of automotive repair and detailing, car paint spray guns play a crucial role. A spray gun is a professional tool used to spray paint onto a car body, providing protection and aesthetic benefits.

[0003] Paint residue inside the spray gun will solidify after drying, clogging nozzles, air lines, or needle valves. This can lead to uneven spraying, interrupted spraying, or even damage to the spray gun. Regular and thorough cleaning can prevent this from happening and ensure smooth spraying next time. Therefore, when using an automotive paint spray gun, it is necessary to clean clogged nozzles or spray heads in a timely manner to avoid affecting the spraying quality.

[0004] A search revealed that Chinese utility model patent CN213468371U discloses a painting spray gun cleaning device, comprising a cleaning body with a cleaning chamber inside and an operating port communicating with the cleaning chamber; a water supply component communicating with the cleaning chamber and also communicating with a water supply device; a drying mechanism mounted on the cleaning body, including a first control valve and a blowing assembly connected to the first control valve, the first control valve also being connected to an air supply device, the blowing assembly being used to blow air onto the spray gun; and a controller, with the water supply component and the first control valve both electrically connected to the controller. This application achieves cleaning by first immersing the spray gun in water and then blowing air onto it. However, this device only cleans the surface of the spray gun and cannot effectively clean its interior, thus failing to meet the cleaning needs after spray gun use. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a spray gun cleaning device for automobile repair, and the main technical problem to be solved is how to effectively clean the inside of the spray gun.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A spray gun cleaning device for automobile repair includes a base, on which an operating mechanism and a collection mechanism are provided. The operating mechanism includes an operating table and a fixing component. The fixing component includes a clamp for fixing the spray gun to the operating table. The operating table is provided with a running component, which includes a turntable. The turntable is provided with a lever. The turntable drives the lever to rotate to push the trigger of the spray gun. The collection mechanism includes a cover for collecting waste liquid.

[0008] Furthermore, the control panel is fixedly connected to one side of the top of the base. The top of the control panel is provided with a mounting groove that matches the handle of the spray gun. The clamp is inverted U-shape and is fitted onto the outside of the top of the control panel. Both sides of the clamp are provided with strip openings.

[0009] Furthermore, bolts are fixedly connected to the inner sides of the two strip openings on both sides of the base. A nut is threaded onto the outer side of one end of each bolt. The diameter of the nut is larger than the width of the strip opening. Several wrenches are fixedly connected to the outer side of the nut.

[0010] Furthermore, two side plates are fixedly connected to the top of one side of the control panel. Each side plate has a circular through hole at one end, and the two side plates are rotatably connected to the same rotating shaft at the circular through hole. There are two turntables, which are fixedly connected to the two ends of the rod between the two side plates at the rotating shaft. The lever is fixedly connected to one side between the two turntables, and the lever is covered with a protective sleeve made of rubber.

[0011] Furthermore, one end of the rotating shaft is connected to a driven wheel via a key, and a motor is fixedly connected to the top of the base below the rotating shaft. One end of the motor's output shaft is connected to a driving wheel via a key. Both the driving wheel and the driven wheel are belt pulleys, and the same belt is fitted around the outside of both the driving wheel and the driven wheel. The diameter of the driving wheel is smaller than the diameter of the driven wheel.

[0012] Furthermore, a waste liquid tank is fixedly connected to the other side of the top of the base. The top of the waste liquid tank has an inlet, and a pipe is fixedly connected to the inlet. The pipe is made of metal shaped flexible tubing. The cover is fixedly connected to the top of the pipe, and the protective cover is fixedly connected to the inside of the cover. The material of the protective cover is sponge.

[0013] Furthermore, gaskets are fixedly connected to the inner wall of the top of the clamping plate and the inner wall of the operating table in the mounting groove. The gaskets are made of rubber.

[0014] The beneficial effects of this utility model are as follows:

[0023] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0024] Example 1

[0025] See attached document Figure 1-2 This application provides a spray gun cleaning device for automobile repair, including a base 1. The base 1 is equipped with an operating mechanism and a collection mechanism. The operating mechanism includes an operating table 2 and a fixing component. The fixing component includes a clamping plate 8, which is used to fix the spray gun on the operating table 2 to ensure the stability of the spray gun during the cleaning process and to ensure the smooth progress of the cleaning process. The operating table 2 is equipped with a running component, including a turntable 9. The turntable 9 is equipped with a lever 13. The turntable 9 drives the lever 13 to rotate and push the trigger of the spray gun. After the cleaning fluid is injected into the material tank of the spray gun, the spray gun can spray out the cleaning fluid by repeatedly pushing the trigger of the spray gun, so that the cleaning fluid flows inside the spray gun and thus achieves the effect of cleaning its internal cavity. The collection mechanism includes a cover 10, which is used to collect waste liquid. The inside of the cover 10 is equipped with a protective cover 18 for wrapping the nozzle of the spray gun.

[0026] Preferably, the operating table 2 is fixedly connected to one side of the top of the base 1. The top of the operating table 2 is provided with a mounting groove that matches the handle of the spray gun. The clamping plate 8 is inverted U-shape and is fitted onto the outside of the top of the operating table 2. Both sides of the clamping plate 8 have slotted openings. Bolts 6 are fixedly connected to the inner sides of the two slotted openings on both sides of the base 1. Nuts 5 are threaded to the outer side of one end of each bolt 6. The diameter of the nuts 5 is larger than the width of the slotted openings. Several wrenches 7 are fixedly connected to the outer side of the nuts 5.

[0027] When the spray gun needs to be cleaned, its handle can be placed in the mounting slot on the operating table 2, and its trigger can be placed between the rotating shaft 12 and the operating table 2. Then press the clamp plate 8 onto the spray gun. After adjusting the clamp plate 8 to press the spray gun, the nut 5 can be turned by the wrench 7. Since the rotation of the nut 5 outside the bolt 6 can gradually approach the clamp plate 8, the nut 5 can be used to fix the clamp plate 8, thereby fixing the spray gun with the clamp plate 8.

[0028] Preferably, two side plates 4 are fixedly connected to the top of one side of the operating table 2. Each side plate 4 has a circular through hole at one end, and the two side plates 4 are rotatably connected to the same rotating shaft 12 at the circular through hole. There are two turntables 9, which are fixedly connected to the two ends of the rod between the two side plates 4 at the rotating shaft 12. The lever 13 is fixedly connected to one side between the two turntables 9. The lever 13 is covered with a protective sleeve 14 made of rubber. The protective sleeve 14 can replace the lever 13 in contact with the wrench of the spray gun, so it can play a protective role between the two, thereby avoiding wear caused by repeated pushing of the trigger.

[0029] Preferably, one end of the rotating shaft 12 is connected to the driven wheel 3 via a key, and the top of the base 1 is fixedly connected to the motor 15 below the rotating shaft 12. One end of the output shaft of the motor 15 is connected to the driving wheel 16 via a key. Both the driving wheel 16 and the driven wheel 3 are pulleys. The same belt 17 is fitted around the outside of the driving wheel 16 and the driven wheel 3. The diameter of the driving wheel 16 is smaller than the diameter of the driven wheel 3. The small-diameter driving wheel 16 drives the large-diameter driven wheel 3 to rotate, which can achieve the effect of deceleration. Therefore, the speed of the push trigger is reduced, ensuring that the cleaning fluid can be sprayed out smoothly.

[0030] Then, cleaning fluid can be poured into the material tank of the spray gun, and the motor 15 can be started. The motor 15 can drive the drive wheel 16 to rotate. The drive wheel 16 drives the driven wheel 3 to rotate through the belt 17. The driven wheel 3 drives the turntable 9 to rotate through the rotating shaft 12. The turntable 9 drives the lever 13 to rotate, which can push the trigger of the spray gun, so that the spray gun sprays out cleaning fluid. By utilizing the flow of cleaning fluid in the spray gun during this process, its inner cavity can be cleaned.

[0031] During the rotation of lever 13, the lever 13 can push the trigger when it moves closer to the operating table 2, and the lever 13 can return the trigger to its original state when it moves away from the operating table 2. Therefore, the continuous rotation of lever 13 can repeatedly push the trigger, thereby causing the spray gun to continuously spray cleaning fluid to achieve an effective and thorough cleaning effect.

[0032] Preferably, a waste liquid tank is fixedly connected to the other side of the top of the base 1. The top of the waste liquid tank has an inlet, and a pipe 11 is fixedly connected to the inlet of the waste liquid tank. The pipe 11 is made of metal shaped flexible tubing. The cover 10 is fixedly connected to the top of the pipe 11, and the protective cover 18 is fixedly connected to the inside of the cover 10. The material of the protective cover 18 is sponge.

[0033] After the spray gun is fixed, the pipe 11 made of metal shaped flexible hose can be bent to adjust the position of the cover 10 so that it covers the outside of the spray gun nozzle and the cover 18 wraps around the spray gun nozzle.

[0034] Therefore, the cleaning fluid sprayed by the spray gun will be confined within the casing 10 and flow into the waste liquid tank through the pipe 11, thus enabling centralized collection of waste liquid. In addition, the protective cover 18 made of sponge material can absorb residual liquid at the nozzle, thus preventing waste liquid backflow and preventing secondary pollution.

[0035] Example 2

[0036] See attached document Figure 3 This application provides a spray gun cleaning device for automobile repair. Compared with embodiment 1, in order to ensure the stability and safety of the spray gun during the cleaning process, a gasket 19 is fixedly connected to the inner wall of the top of the clamping plate 8 and the inner wall of the mounting groove of the operating table 2. The material of the gasket 19 is rubber.

[0037] When the spray gun is fixed using the operating table 2 and the clamping plate 8, the rubber gasket 19 can protect the spray gun in the mounting groove on the operating table 2 and on the inner wall of the top of the clamping plate 8, and increase the friction between the spray gun and the two, thus ensuring the safety and stability of the spray gun during the cleaning process.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
