A test nozzle is connected to one end of the connecting pipe, and different connecting pipes are connected to nozzles of different calibers. The other end of the connecting pipe is made to stick to the pipe mouth of the outlet pipe by rotating the adjusting disk. A sealing structure is connected to the connecting pipe, and the sealing structure can slide on the connecting pipe, so that the sealing structure is placed at the connection between the connecting rod and the outlet pipe, so that the connection between the connecting rod and the outlet pipe is sealed to prevent water leakage.

The bottom of the test tank 19 is inclined, and the lower part of the bottom of the test tank 19 is close to the lower water tank 4.

[0034] like Figure 3-5As shown, the sealing structure 10 includes a sealing ring 12, a fixed ring 13, and a guide ring 14. The sealing ring 12 is connected to the inner wall of the fixed ring 13. The fixed ring 13 has a plurality of protrusions 15 connected to both ends. A limit ring 16 is sleeved on the fixed ring 13 and is slidably connected to the fixed ring 13. The limit ring 16 is adapted to fit the protrusions 15. The guide ring 14 is connected to the inner wall of the sealing ring 12 at its end. The inner wall of the guide ring 14 is an inclined surface. The lower water trough 4 is provided with a rotation groove 17. A rotating rod 18 is connected to the adjusting disk 8. The rotating rod 18 is plugged into the rotation groove 17. The cross-section of the rotating rod 18 and the rotation groove 17 are both T-shaped.

[0035] like Figure 2 、 6 As shown in Figures 7 and 8, a test slot 19 is provided on the operating table 1. The test slot 19 is connected to the lower water tank 4 and is coaxially aligned. A partition 39 is inserted between the test slot 19 and the lower water tank 4. A test board 20 is movably connected to the test slot 19. A movable structure 21 is provided on one side of the test board 20. The movable structure 21 includes a movable block 22, a screw 23, and a fixed block 24. The test board 20 is connected to the movable block 22, and the fixed block 24 is connected to the operating table 1. One end of the screw 23 is connected to the fixed block 24, and the other end of the screw 23 is threadedly connected to the movable block 22.

[0036] like Figure 7 、 8 As shown, the movable block 22 is provided with a connecting rod 25, and a circular groove 26 is provided on the surface of the movable block 22. One end of the connecting rod 25 is rotatably connected to the movable block 22 through the circular groove 26. The other end of the connecting rod 25 is connected to an insert plate 27, which has a slot 28, and the test board 20 is inserted into the slot 28. The connecting rod 25 is connected to a connecting block 29, one end of which is connected to the connecting rod 25, and the other end of the connecting block 29 is connected to a disc 30. The groove wall of the circular groove 26 is provided with a slide rail 31. The connecting block 29 is engaged with the circular groove 26, and the disc 30 is slidably connected to the slide rail 31. A stabilizing structure 32 is provided on the other side of the test board 20. The stabilizing structure 32 includes a stabilizing block 33, a support rod 34 and a second fixed block 35. The second fixed block 35 is connected to the operating table 1, one end of the support rod 34 is connected to the second fixed block 35, and the other end of the support rod 34 is plugged into the stabilizing block 33. A stabilizing rod 36 is connected to the stabilizing block 33, and the stabilizing rod 36 is connected to the plug-in plate 27.

[0037] like Figure 1-8As shown: a bracket 43 is connected to the operating table 1, and the water supply tank 3 is installed on the bracket 43. The upper end of the water inlet pipe 6 is connected to the lower water level of the water supply tank 3, and the other end of the water inlet pipe 6 is connected to the water inlet of the test water pump 2, so that water flows into the test water pump 2. One end of the water outlet pipe 7 is connected to the water outlet of the test water pump 2, and the other end passes through the operating table 1 and enters the lower water tank 4, so that water flows through the test water pump 2 and enters the lower water tank 4. A bottom plate 42 is connected to the bottom of the operating table 1. The bottom plate 42 is used to place the recovery box 5. The upper end of the collection pipe 11 is connected to the lower water tank 4, and the lower end is connected to the recovery box 5, so that the water after testing enters the recovery box 5. Rollers 41 are connected under the bottom plate 42 to facilitate the flexible movement of the test equipment, facilitate the change of test sites, and enhance the convenience of use.

[0038] Multiple connecting pipes 9 can be connected to the adjustment disk 8 according to the different types of test nozzles 38 required. In this embodiment, two are used as an example to speed up the test progress and efficiency. At the same time, multiple water outlet pipes 7 can be connected to the lower water tank 4, which can serve as a control test group for the test nozzles 38 and improve the test efficiency.

[0039] The sealing ring 12 is made of rubber material, and the ridges 15 are evenly arranged on the outside of the sealing ring 12. Gaps are left between adjacent ridges 15 to facilitate the movement of the ridges 15. At the same time, the ridges 15 are connected to the end faces of the fixing ring 13 as an integral whole, so that the surface has an arc-shaped transition, so that the limiting ring 16 can smoothly transition from the fixing ring 13 to the ridges 15. At the same time, when the limiting ring 16 moves to the strips 15, it can squeeze the rubber sealing ring 12, so that the connection is completely sealed so that the test nozzle 38 can spray out, thereby improving the accuracy of the test.

[0040] The guide ring 14 is connected to the inner wall of the port of the sealing ring 12. The inner wall of the guide ring 14 is an inclined surface and opens toward the water outlet pipe 7, so that when the fixing ring 13 is moved, the guide ring 14 can easily carry the sealing ring 12 into the water outlet pipe 7. At the same time, it can limit the limiting ring 16, so that the sealing ring 12 protruding due to the limiting ring 16 cannot be crossed, and then the limiting ring 16 is placed away from the protruding strip 15, thereby improving the stability of the structure movement.

[0041] The recycling tank 5 has a built-in circulating filtered water system. The recycling tank 5 and the water supply tank 3 are connected by a pipe, allowing used water to be filtered and returned to the water supply tank 3 for recycling, eliminating the need for frequent water additions and improving the device's ease of use. A switch 40 and an electrical control box 37 are connected to the operating table 1. The switch 40 is electrically connected to the test water pump 2 and the circulating filtered water system to control its operation. The electrical control box 37 is electrically connected to the test water pump 2 and the recycling tank 5 (the recycling tank 5 is connected to a weighing device that is electrically connected to the electrical control box 37 for data transmission). The electrical control box 37 contains electronic devices such as a digital flow meter and a time counter for recording and displaying test data, making the test equipment more intelligent.

[0042] The partition 39 is inserted into the lower water tank 4 and abuts against the wall of the lower water tank 4 near the test tank 19 to isolate the lower water tank 4 and the test tank 19, preventing water from entering the test tank 19 during the flow test of the water pump and increasing water loss, thereby ensuring the accuracy of the test results.

[0043] One end of the rotating rod 18 is connected to the adjusting disk 8. The rotating rod 18 is in the shape of a round rod and the connecting structure at the other end is in the shape of a circle, so that the cross-section of the rotating rod 18 is in the shape of a T, so that the rotating rod 18 can be easily rotated to adjust the connection between different connecting pipes 9 and the water outlet pipe 7.

[0044] The connection shape between the test trough 19 and the lower water tank 4 is T-shaped. The test trough 19 is a long strip structure. At the same time, the bottom of the test trough 19 is a sloped bottom to facilitate the introduction of flowing water into the lower water tank 4 for collection and recycling.

[0045] When in use, the flow rate of the test water pump 2 is tested: the test water pump 2 is turned on by the switch 40, so that the test water pump 2 can pump water, and the electrical control box 37 is turned on to record and display the water volume, wherein the water flows from the water supply tank 3 on the bracket 43 through the water inlet pipe 6 into the water inlet of the test water pump 2, and then enters the water outlet pipe 7 from the water outlet of the test water pump 2 and then into the lower water tank 4, so that the water flows through the test water pump 2 into the lower water tank 4, and the collecting pipe 11 connected to the bottom of the lower water tank 4 allows the water to flow into the recovery tank 5. The water in the recovery tank 5 passes through the circulating filtered water system and the pipeline and then returns to the water supply tank 3, completing a water cycle. At the same time, the amount of water flowing through per unit time is displayed and recorded by the electrical control box 37.

[0046] Test the water discharge status of different nozzles: Rotate the adjustment dial 8 to align the connecting pipe 9 connected to the test nozzle 38 to be tested with the nozzle opening of the outlet pipe 7. Then, move the sealing structure 10 so that the guide ring 14, with the fixing ring 13 and the sealing ring 12, enters the connection between the connecting pipe 9 and the nozzle opening of the outlet pipe 7. Move the limiting ring 16 to press the sealing ring 12 inward, thereby ensuring a stable seal between the connecting pipe 9 and the outlet pipe 7. Then, start the test water pump 2 to supply water to test the water discharge status of the nozzle, and obtain the water demand and spray status of different nozzles per unit time. When changing the test, reset the limiting ring 16, move the fixing ring 13 away from the outlet pipe 7, and rotate the adjustment dial 8 to change to the next caliber test nozzle 38 for testing.

[0047] To test the flushing capabilities of different nozzles, remove the partition 39 and use different nozzles to impact the test plate 20 with water jets to determine the flushing capabilities of nozzles 38 of different calibers. Rotate the movable block 22, causing it to move on the screw 23, driving the insert plate 27 within the test slot 19, changing the distance between the nozzle and the test plate 20 to determine the effect of different flushing distances on flushing capabilities and obtain test results. By changing the material of the test plate 20 (e.g., tile floor, wood board) or the type of stain on the material, different calibers and spacings can be used to determine the flushing capabilities under different materials or stain types. These three groups can be used as cross-reference tests to improve the depth and accuracy of the test, completing the test of the nozzle as a spray cleaning tool for vacuum cleaners.
