[0002] In many fields of metal processing and manufacturing, such as automobile manufacturing, aerospace, machinery manufacturing, and building decoration, metal surface treatment is a crucial step. Among them, cleaning is the basic step of metal surface treatment. Its purpose is to remove impurities such as oil, rust, scale, and dust from the metal surface, so as to provide a clean and smooth surface for subsequent processes such as coating, electroplating, and welding, and to ensure the treatment effect and quality.
[0003] During metal surface cleaning, the cleaning medium splashes during spraying, and dirt detached from the metal surface also scatters everywhere. This splashed cleaning medium and dirt easily adhere to the surface of the spray gun, including the outer casing and the area around the handle. The contamination of the spray gun surface not only affects the cleanliness of the equipment, but also, on the one hand, the accumulation of dirt may obscure some markings and operating buttons on the spray gun surface, causing inconvenience to operators and increasing the risk of misoperation; on the other hand, the dirt on the spray gun surface may fall back onto the metal surface during the cleaning process, causing secondary pollution and affecting the cleaning quality of the metal surface. Therefore, we propose a self-cleaning cleaning spray gun for metal surface treatment. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a self-cleaning cleaning spray gun for metal surface treatment, comprising:
[0027] Metal parts cleaning box 1, the top of metal parts cleaning box 1 is provided with a through groove 8;
[0028] The spray gun cleaning structure is located on the metal parts cleaning box 1.
[0029] The spray gun cleaning structure includes a water supply hose 7, a cleaning spray gun body 4, a spray gun head 9, an external threaded ring 10, a corrugated hose 13, an external threaded ring 21, and a knob ring 12. The water supply hose 7 is installed on the top of the metal cleaning box 1. One end of the water supply hose 7 passes through the through groove 8 and is threadedly connected to the water inlet end of the cleaning spray gun body 4. The spray gun head 9 is fixedly connected to the cleaning spray gun body 4. The external threaded ring 10 is threadedly connected to the inside of the spray gun head 9. The corrugated hose 13 is fixedly connected to the end of the external threaded ring 10 away from the spray gun head 9. The end of the corrugated hose 13 away from the external threaded ring 10 is fixedly connected to the external threaded ring 21. The knob ring 12 is fixedly connected to the end of the external threaded ring 21 away from the corrugated hose 13.
[0030] The spray gun cleaning structure also includes four fixing plates 15, an internal threaded positioning ring 14, and a limiting ring 17. The four fixing plates 15 are all fixedly connected to the outer surface of the spray gun head 9. The ends of the four fixing plates 15 away from the spray gun head 9 are all fixedly connected to the outer surface of the internal threaded positioning ring 14. A limiting groove 16 is opened inside the external threaded ring 11. The limiting ring 17 is slidably connected inside the limiting groove 16. The limiting ring 17 is fixedly sleeved on the outer surface of the corrugated hose 13. The four fixing plates 15 are arranged in a circular array on the spray gun head 9.
[0031] The metal parts cleaning tank 1 has a hook 6 fixedly connected inside, the hook 6 has an "L" shaped structure, the metal parts cleaning tank 1 has a drain plate 5 fixedly connected inside, the top of the drain plate 5 has a baffle 3 fixedly connected, and the metal parts cleaning tank 1 has a collection box 2 slidably connected inside, the collection box 2 and the bottom of the drain plate 5 are in sliding contact.
[0032] Furthermore, when using this device, if it is necessary to clean the spray gun used for metal surface treatment or to clean metal parts, the water supply hose 7 is connected to an external water source. The water source enters the cleaning spray gun body 4 through the water supply hose 7. The operator holds the cleaning spray gun body 4 and turns on the water source switch. The water flow is sprayed out from the spray gun head 9. At this time, the metal parts placed in the metal parts cleaning box 1 can be initially rinsed to remove larger dust, impurities, etc. from the surface of the metal parts.
[0033] When cleaning the spray gun is required, the operator can rotate the knob ring 12. Rotating the knob ring 12 will rotate the external threaded ring 11 out of the internal threaded positioning ring 14. At the same time, since the limiting ring 17 is fixedly sleeved on the outer surface of the corrugated hose 13 and slidably connected in the limiting groove 16 opened inside the external threaded ring 11, the corrugated hose 13 will not rotate with the external threaded ring 11 during the movement of the external threaded ring 11. This allows the knob ring 12 to drive the corrugated hose 13 to extend or retract. When the corrugated hose 13 extends, its other end can bend and rotate freely, and water can be sprayed out through the corrugated hose 13 to clean the outside of the spray gun.
[0034] The metal parts cleaning tank 1 has an L-shaped hook 6 fixedly connected inside. The operator can hang the cleaning spray gun body 4 on the hook 6. The water leakage plate 5 inside the metal parts cleaning tank 1 serves to separate and filter. During the cleaning process, water carrying impurities falls from the metal parts and lands on the water leakage plate 5. The baffle 3 on the water leakage plate 5 can prevent water and impurities from splashing out. At the same time, the holes in the water leakage plate 5 allow water to pass through, while impurities remain above the water leakage plate 5. The wastewater flowing down from the water leakage plate 5 will enter the collection box 2. After the cleaning operation is completed, the operator can pull the collection box 2 out of the metal parts cleaning tank 1 to centrally treat the wastewater and impurities and keep the inside of the metal parts cleaning tank 1 clean.
[0035] Through the sliding engagement of the limiting ring 17 and the limiting groove 16, when the external threaded ring 11 moves, the corrugated hose 13 will not rotate with it, but can smoothly extend or retract, so that the corrugated hose 13 can clean the outside of the spray gun, avoiding the problem of contamination of the spray gun surface due to splashing of cleaning medium and scattering of dirt, reducing the risk of misoperation, and preventing dirt from falling back onto the metal surface and causing secondary contamination, thus ensuring the cleaning quality of the metal surface.
[0036] Structural Description: Metal Parts Cleaning Box 1: The main container of the device, used to place metal parts for cleaning operations. A through groove 8 is opened on the top, and components such as a drain plate 5 and hooks 6 are installed inside to provide cleaning space.
