[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example:

[0027] See also Figure 1-5 The manual cleaning spray device includes a water spray gun 1, which is composed of a gun body 101 and a water spray head 102. The gun body 101 and the water spray head 102 are rotatably connected. A lamp body 103 is arranged on the gun body 101. When the workpiece is manually cleaned, it can be properly illuminated to facilitate observation of whether the workpiece is cleaned. The lamp body 103 can be arranged in multiple groups in the circumferential direction of the gun body 101. A gear ring 2 is arranged at one end of the water spray head 102. The end of the gun body 101 connected to the water spray head 102 A driving mechanism 3 is arranged inside, and the driving mechanism 3 is a micro motor. A gear 4 is connected to the output shaft of the driving mechanism 3, and the gear 4 can mesh with the gear ring 2. The driving mechanism 3 drives the gear 4 to rotate, thereby driving the gear ring 2 meshing with it to rotate. Since the water spray head 102 is coaxially connected to the gun body 101, and the gear ring 2 is coaxial with the water spray head 102, the rotation of the gear ring 2 drives the water spray head 102 to rotate, so that the water spray head 102 rotates and sprays water, which can reduce water splashing when spraying water.

[0028] In the present application, the water spray head 102 includes a shell 7, a fixed tube 8 is sleeved on the outer side of the shell 7, a convex ring 803 is provided on the side of the fixed tube 8 close to the gun body 101, and the gear ring 2 is sleeved on the convex ring 803. When the water spray head 102 is installed on the gun body 101, the convex ring 803 extends to the inner side of the gun body 101.

[0029] In the present application, a water pipe 6 is provided inside the gun body 101, and a fixed body is sleeved on the water pipe 6. The fixed body is provided between the inner wall of the gun body 101 and the outer wall of the water pipe 6. The end of the water pipe 6 is rotatably connected with a tube body 5, and the tube body 5 extends into the shell 7. Water is transmitted to the tube body 5 through the water pipe 6, and then sprayed out from the shell 7.

[0030] In the present application, a limiting protrusion 701 is provided on the outer wall of the shell 7, and a limiting groove 801 matching the limiting protrusion 701 is provided on the inner wall of the fixed cylinder 8. Through the cooperation between the limiting protrusion 701 and the limiting groove 801, the fixed cylinder 8 is sleeved outside the shell 7, so that the shell 7 and the fixed cylinder 8 will not rotate relative to each other in the circumferential direction.

[0031] In the present application, an annular groove 802 is provided on the side of the fixed tube 8 close to the gun body 101, and the gear shaft of the gear 4 slides in cooperation with the annular groove 802, and the end of the gear shaft of the gear 4 extends into the annular groove 802. When the fixed tube 8 rotates, the gear shaft will slide relative to the annular groove 802, and the annular groove 802 plays a certain limiting role on the gear shaft, thereby ensuring the stability of the gear 4.

[0032] In the present application, a limiting sleeve 9 is sleeved on the end of the shell 7, and one inner end of the limiting sleeve 9 contacts the fixed cylinder 8. The setting of the limiting sleeve 9 limits the axial position of the fixed cylinder 8, and the fixed cylinder 8 is movably connected to the limiting sleeve 9.

[0033] Among them, the outer wall of the limiting sleeve 9 near one end of the fixed cylinder 8 is provided with an annular slide rail A901, and the convex ring 803 is penetrated by a limiting screw A804, which extends into the annular slide rail A901. The end of the limiting screw A804 is slidably matched with the annular slide rail A901. When the fixed cylinder 8 rotates, the limiting screw A804 is driven to rotate, and the limiting screw A804 can slide in the annular slide rail A901, so that the limiting sleeve 9 does not need to rotate with the fixed cylinder 8. Figure 4 As shown, when the water spray head 102 is installed on the gun body 101 , the end of the limiting sleeve 9 contacts the boss on the fixed body sleeved on the water pipe 6 , thereby limiting the installation position of the shell 7 extending into the gun body 101 .

[0034] Among them Figure 5 As shown, the axial position of the limit sleeve 9 and the shell 7 is fixed by a limit screw B. An annular slide rail B is provided on the outer wall of the shell 7. The limit screw B is threadedly connected to the limit sleeve 9. The end of the limit screw B extends into the annular slide rail B. The end of the limit screw B is slidably matched with the annular slide rail B, so that when the shell 7 rotates, the limit sleeve 9 does not rotate with it.

[0035] In the present application, the inner wall of the shell 7 is provided with an internal thread, and the outer wall of the tube body 5 is provided with an external thread matching the internal thread, so that the shell 7 and the tube body 5 are connected together by threads, and the tube body 5 and the water pipe 6 are rotatably connected. When the shell 7 rotates, the tube body 5 can be driven to rotate along with it;

[0036] An axial elastic telescopic rod is connected to one end of the gear shaft of the gear 4 close to the driving mechanism 3, and the axial elastic telescopic rod is connected to the driving mechanism 3. Through the setting of the elastic telescopic rod, when the tube body 5 is installed in the shell 7, the gear 4 can be pushed to the side of the driving mechanism 3. After the tube body 5 is installed, the gear 4 is moved toward the gear ring 2 to make the gear 4 mesh with the gear ring 2. Through the setting of the elastic telescopic rod, the installation of the shell 7 and the tube body 5 is more convenient.

[0037] The present application also includes a cleaning table 10, a water tank 11 is arranged below the cleaning table 10, and the water spray gun 1 is connected to the water tank 11 through a water pipe. When the cleaning parts are received, the parts are placed on the cleaning table 10, and the water source of the water spray gun 1 is provided by the water tank 11.

[0038] In the present application, a turntable 12 is provided on the top of the cleaning table 10, and a workpiece placement slot is provided on the turntable 12. The turntable 12 is driven by a motor to rotate, and the parts on the workpiece placement slot are driven to rotate, so that the parts are cleaned around with a water spray gun 1.

[0039] Working principle: When cleaning the workpiece, the staff uses the water spray gun 1 to clean the workpiece placed on the turntable 12. During cleaning, water falls on the cleaning table 10. The cleaning table 10 is provided with a water outlet, and the water used for cleaning flows to the outside. When the water spray gun 1 is in use, the driving mechanism 3 drives the gear 4 to rotate, thereby driving the gear ring 2 meshing with it to rotate. Since the water spray head 102 is coaxially connected to the gun body 101, and the gear ring 2 is coaxial with the water spray head 102, the rotation of the gear ring 2 drives the water spray head 102 to rotate, so that the water spray head 102 rotates while spraying water, which can reduce water splashing when spraying water, and facilitate the cleaning of the cleaning water.

[0040] In the present application, when the water spray head 102 is installed with the gun body 101, the fixing tube 8 is first sleeved on the outer wall of the shell 7 so that the limiting protrusion 701 and the limiting groove 801 cooperate, and then the limiting sleeve 9 is sleeved into the end of the shell 7 so that the limiting sleeve 9 contacts with the fixing tube 8, and the limiting screw B extends to the annular slide rail B on the outer wall of the shell 7 to fix the axial position of the limiting sleeve 9 and limit the axial position of the fixing tube 8 at the same time, and then the shell 7 is brought close to the tube body 5, so that the tube body 5 is screwed into the shell 7, and when the gear ring 2 is close to the gear 4, Since the gear shaft of the gear 4 is connected with an axial elastic telescopic rod near one end of the driving mechanism 3, the gear 4 can be pushed to one side of the driving mechanism 3, and the housing 7 and the fixed cylinder 8 are further rotated and moved to one side of the gun body 101, and then the elastic telescopic rod is loosened to make the elastic telescopic rod push the gear 4 to mesh with the gear ring 2. During the meshing process of the gear 4 and the gear ring 2, the fixed cylinder 8 can be slightly rotated to make the gear 4 and the gear ring 2 accurately mesh. By setting the elastic telescopic rod, the meshing process of the gear 4 and the gear ring 2 is more convenient when the housing 7 and the pipe body 5 are installed. At the same time, in order to improve the stability of the sprinkler head fixing, the limiting sleeve 9 and the gun body 101 can also be connected by a latch or a bolt, and the limiting sleeve 9 can also be clamped with the inner wall of the gun body 101.
