A waterproof plate 14 is also provided at one end of the 13, a waterproof bucket 4 is provided on the waterproof plate 14, a fixing rod 22 is provided on the waterproof bucket 4, a connecting box 21 penetrated by the fixing rod 22 is provided on the fixing rod 22, a circulating water pipe 6 is provided on the connecting box 21, one end of the circulating water pipe 6 is connected to a water pump 25, an air bag 34 is also provided on the circulating water pipe 6, a first piston cylinder 7 is provided on the air bag 34, a first piston rod 30 is provided on the first piston cylinder 7, a fixing plate 32 is provided on the first piston rod 30, a placing plate 20 is provided on the fixing plate 32, a second piston rod 23 is provided on the placing plate 20, and a second piston rod 24 is provided on the second piston rod 25. The plug rod 23 is provided with a second piston cylinder 9, the second piston cylinder 9 is provided with an air delivery pipe 17, the air delivery pipe 17 is provided with an air storage tank 8, the air delivery pipe 17 is also provided with a knob 26, the knob 26 is provided with an air blocking disk 18, the base 1 is also provided with a telescopic column 10, the telescopic column 10 is provided with a fixed column 11, the fixed column 11 is provided with a plurality of push rods 12, the plurality of push rods 12 are provided with a plurality of push plates 19, and the base 1 is also provided with a water tank 31. When starting to clean small hardware, the hardware is placed on the placement tray 20, and the gravity of the placed small hardware drives the placement tray 20 to squeeze The second piston rod 23 is pressed, and the second piston rod 23 moves to discharge the air in the second piston cylinder 9 into the air storage tank 8. At the same time, the placement plate 20 moves to drive the fixing plate 32 to move, and drive the first piston rod 30 to move, so as to extract a part of the gas in the air bag 34. The squeezing effect of the placement plate 20 on the hardware is different according to the gravity of the placed hardware, so that the amount of gas extracted from the air bag 34 is different, so that different amounts of water can pass through the circulating water pipe 6, so as to control different hardware to spray different amounts of water for flushing, avoid blindly spraying water to clean the hardware, reduce the use of water resources, and save water resources.

[0022] Water is pumped from the water tank 31 into the circulating water pipe 6 through the water pump 25, and enters the connecting box 21 through the water pump 25, and the small hardware in the flushing bucket 13 is flushed through the nozzle. When the placement tray 20 is in a stable state, the rotating air blocking disk 18 prevents the gas in the gas storage tank 8 from entering the second piston cylinder 9, so that the placement tray 20 will not return to the original position temporarily, ensuring that the instantaneous amount of water passing through the circulating water pipe 6 remains unchanged.

[0023] At the same time, the small hardware on the storage tray 20 is pushed into the flushing bucket 13 for flushing through the push rod 12. After the flushing is completed, the air blocking disk 18 is rotated again to allow the gas in the gas storage tank 8 to return to the second piston cylinder 9, so that the storage tray 20 returns to the original position for the next flushing. After the flushing is completed, the water in the flushing bucket 13 flows out from the holes on the waterproof bucket 4, is filtered by the filter plate 33 inside the filter station 5, and is discharged into the water tank 31 again through the sewage pipe 15 for reuse, thereby reusing water resources and saving water resources.

[0024] The filter disc 33 is of double-layer detachable design, and a hole is arranged inside the filter disc 33, and the size is adapted to the support platform 16. The water after flushing in the flushing bucket 13 flows into the filter platform 5 from the hole on the waterproof bucket 4, and the oil and waste residue in the water after cleaning are filtered through the filter disc 33, so that the relatively clean water re-enters the water tank 31 through the sewage pipe 15, so that water resources are reused, water resources are saved, and waste is avoided. At the same time, it is prevented that sewage flows out to cause environmental pollution. The filter disc 33 in the filter platform 5 can be replaced to achieve a long-term filtering effect.

[0025] A plurality of water outlets are designed on the flushing bucket 13, and a blocking block is also provided on the flushing bucket 13. The waterproof bucket 4 is provided with an opening, and the filter platform 5 covers the opening. The blocking block ensures that when the flushing bucket 13 rotates, the hardware inside the flushing bucket 13 is driven to turn over to prevent only one side of the hardware from being flushed. The hardware is fully flushed to ensure the cleaning effect. At the same time, the waterproof bucket 4 wraps the flushing bucket 13 to ensure that the sewage used to clean the hardware can only flow out from the opening on the waterproof bucket 4 to prevent the sewage from polluting the environment.

[0026] One end of the water pump 25 is connected to the water tank 31. The water in the water tank 31 is pumped out by the water pump 25 and transported to the circulating water pipe 6. The water is then transported to the connecting box 21 to clean the hardware in the flushing barrel 13, thereby reusing water resources.

[0027] Gaps are provided on the plurality of push plates 19, and the plurality of push rods 12 are respectively connected to the push plates 19. The push plates 19 push the hardware on the storage tray 20. Gaps are provided between the plurality of push plates 19, and the sizes thereof are respectively adapted to the first piston cylinder 7 and the knob 26, so that the push plates 19 can push the hardware without colliding with the device.

[0028] The second piston cylinder 9 is hollow in design, and the internal size of the second piston cylinder 9 is adapted to the second piston rod 23. The hardware placed on the placement plate 20 squeezes the placement plate 20, driving the placement plate 20 to squeeze the second piston rod 23, driving the second piston rod 23 to move inside the second piston cylinder 9, squeezing the gas inside the second piston cylinder 9, allowing the gas to enter the gas storage tank 8. The movement of the placement plate 20 drives the fixing plate 32 to move, driving the first piston rod 30 to move, extracting the gas in the air bag 34, shrinking the air bag 34, and allowing a certain amount of water to pass through the circulating water pipe 6.

[0029] The gas storage tank 8 is hollow in design, the gas supply pipe 17 is hollow in design, the gas supply pipe 17 is connected to the knob 26, the size of the knob 26 is adapted to the gas supply pipe 17, and when the storage tray 20 is in a stable state, rotating the knob 26 drives the air blocking disk 18 to rotate, so that the gas storage tank 8 and the second piston cylinder 9 are in a separated state. During the flushing process, the storage tray 20 can be in a stable state, and the air bag 34 will not be restored, ensuring that the instantaneous water intake during the flushing process does not fluctuate greatly, thereby achieving the purpose of controlling the flushing volume.

[0030] The first piston cylinder 7 is hollow in design, and a first piston rod 30 is provided on the first piston cylinder 7. The size of the first piston cylinder 7 is adapted to the first piston rod 30. When the placement plate 20 moves, the first piston rod 30 and the first piston cylinder 7 are driven to move, and the gas in the airbag 34 is extracted to shrink the airbag 34, so that a certain amount of water can pass through the circulating water pipe 6, thereby achieving the purpose of controlling different water intake amounts through the different gravity of the hardware.

[0031] The airbag 34 is hollow in design, and its size matches the circulating water pipe 6 . In the initial state, the airbag 34 blocks the water in the circulating water pipe 6 , causing the circulating water pipe 6 to be blocked, thereby controlling the amount of water in the circulating water pipe 6 that enters the flushing bucket 13 .

[0032] The gas pipe 17 is provided with a hole whose size is adapted to the knob 26. The gas pipe 17 is connected to the gas storage tank 8 and the second piston cylinder 9. The knob 26 is driven to rotate by rotating the air blocking disk 18 to clear and close the gas pipe 17, thereby controlling the gas flow between the second piston cylinder 9 and the gas storage tank 8.

[0033] Working principle: When you start cleaning small hardware, place the hardware on the storage tray 20. The gravity of the placed small hardware drives the storage tray 20 to squeeze the second piston rod 23. The second piston rod 23 moves to discharge the air in the second piston cylinder 9 into the air storage tank 8. At the same time, the movement of the storage tray 20 drives the fixing plate 32 to move, and drives the first piston rod 30 to move, extracting a part of the gas in the air bag 34. The squeezing effect of the gravity of the placed hardware on the storage tray 20 is different, so that the amount of gas extracted from the air bag 34 is different, so that different amounts of water can pass through the circulating water pipe 6, so as to control different hardware to spray different amounts of water for flushing, avoid excessive use of water, reduce the use of water resources, and save water resources. Water is pumped from the water tank 31 into the circulating water pipe 6 through the air bag 34, and enters the connecting box 21 through the air bag 34. The small hardware in the flushing barrel 13 is flushed through the nozzle. When the placement tray 20 is in a stable state, the air blocking disk 18 is rotated so that the gas in the gas tank 8 cannot enter the second piston cylinder 9, so that the placement tray 20 will not return to the original position temporarily, ensuring that the instantaneous amount of water passing through the circulating water pipe 6 remains unchanged. At the same time, the small hardware on the placement tray 20 is pushed into the flushing barrel 13 for flushing through the push rod 12. After the flushing is completed, the air blocking disk 18 is rotated again to allow the gas in the gas tank 8 to return to the second piston cylinder 9, so that the placement tray 20 returns to the original position for the next flushing. After the flushing is completed, the water in the flushing barrel 13 flows out from the holes on the waterproof barrel 4, is filtered through the filter plate 33 inside the filter station 5, and is discharged into the water tank 31 again through the sewage pipe 15 for reuse, thereby reusing water resources and saving water resources.

[0034] The filter disc 33 is designed to be double-layered and detachable, and a hole is arranged inside the filter disc 33, and the size is adapted to the support platform 16. The water after flushing in the flushing barrel 13 flows into the filter platform 5 from the hole on the waterproof barrel 4, and the oil and waste residue in the water after cleaning are filtered through the filter disc 33, so that the relatively clean water re-enters the water tank 31 through the sewage pipe 15, so that water resources are reused, water resources are saved, and waste is avoided. At the same time, sewage is prevented from flowing out and causing environmental pollution. The filter disc 33 in the filter platform 5 can be replaced to achieve a long-term filtering effect. Multiple water outlets are designed on the flushing barrel 13, and an obstruction block is also arranged on the flushing barrel 13. The waterproof barrel 4 is provided with an orifice, and the filter platform 5 covers the orifice. The obstruction block ensures that the hardware inside the flushing barrel 13 is turned over when the flushing barrel 13 rotates, so as to prevent only one side of the hardware from being flushed, which is good for the hardware. The parts are fully rinsed to ensure the cleaning effect. At the same time, the waterproof bucket 4 wraps the flushing bucket 13 to ensure that the sewage used to clean the hardware can only flow out from the holes on the waterproof bucket 4 to prevent sewage from polluting the environment. Water is pumped from the water tank 31 into the circulating water pipe 6 through the water pump 25, and enters the connecting box 21 through the water pump 25. The small hardware in the flushing bucket 13 is rinsed through the nozzle. When the placement tray 20 is in a stable state, the rotating air blocking disk 18 prevents the gas in the gas tank 8 from entering the second piston cylinder 9, so that the placement tray 20 will not return to the initial position temporarily, ensuring that the instantaneous amount of water passing through the circulating water pipe 6 remains unchanged. The air bag 34 is hollow in design, and the size of the air bag 34 is adapted to the circulating water pipe 6. In the initial state, the air bag 34 blocks the water in the circulating water pipe 6, causing the circulating water pipe 6 to be blocked, thereby controlling the amount of water in the circulating water pipe 6 entering the flushing bucket 13.
