DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The water inlet valve of a washing machine is a device used to control the water entering the washing machine. In order to ensure that the water inlet valve can effectively control the water flow during operation, it is necessary to test the air tightness of the water inlet valve. Good air tightness can effectively control the water flow and prevent water leakage. The existing detection device has low detection efficiency and can only test one water inlet valve at a time. Especially in the case of large-scale production or the need for efficient detection, it will consume a lot of time and human resources and it is difficult to meet the needs of batch detection.

[0023] To solve the defects of the above detection device during the detection process, please refer to Figure 1-Figure 5The utility model provides a washing machine water inlet valve detection device, which can detect the air tightness of multiple water inlet valves at one time to meet the needs of batch detection. The detection device is based on a detection box 1, which is made of aluminum alloy. It can reduce the weight while maintaining the overall structural strength of the detection box 1, which is convenient for carrying the equipment. Slide bars 2 are fixedly installed on both sides of the interior of the detection box 1, and a detection platform 3 is fixedly installed on the outside of the two slide bars 2, and a pressure plate 4 is slidably installed on the outside of the two slide bars 2. The pressure plate 4 is arranged above the detection platform 3. The detection platform 3 and the pressure plate 4 can respectively block the water inlet and water outlet of the water inlet valve. A plurality of air inlet heads 17 are arranged at the bottom of the pressure plate 4. The water inlet valve is placed on the detection platform 3. The pressure plate 4 slides down to drive the air inlet head 17 to enter the water inlet of the water inlet valve and block the water inlet. High-pressure gas can be transported to the inside of the water inlet valve through the air inlet head 17. A plurality of air outlets 15 are opened on the detection platform 3, and an exhaust pipe 16 is installed inside the air outlet 15. During detection, the water outlet of the water inlet valve is controlled to be closed. If the water inlet valve If the air tightness is insufficient, the high-pressure gas delivered by the air inlet head 17 will enter the exhaust pipe 16 along the air outlet 15. A water tank 11 is installed inside the detection box 1, and the lower end of the exhaust pipe 16 extends to the inside of the water tank 11. Water is added to the water tank 11. The gas in the exhaust pipe 16 enters the water to produce bubbles. On the contrary, if the air tightness of the water inlet valve is good, the gas in the water inlet valve cannot leak from the exhaust pipe 16. The staff can detect whether the water inlet valve is leaking by whether bubbles are generated in the water in the water tank 11, so as to intuitively judge the air tightness of the water inlet valve. In addition, the inner wall of the detection box 1 is slidably connected to multiple groups of clamps, and the number of clamps is not less than three groups. The clamps include two clamps 8. Multiple groups of clamps can synchronously clamp multiple water inlet valves to achieve preliminary fixation of the water inlet valves, and the clamping of the clamps can adjust the horizontal position of the water inlet valve so that the water inlet of the water inlet valve is aligned with the air outlet 15, which is convenient for subsequent detection work.

[0024] In order to achieve the effect of multiple sets of clamping parts to synchronously clamp multiple water inlet valves, refer to Figure 2 and Figure 3 As shown, a servo motor 10 is fixedly installed on one side of the detection box 1, and a threaded rod 9 is fixedly connected to the output end of the servo motor 10. The threaded rod 9 is rotatably installed on the inner wall of the detection box 1, and the end of the clamping plate 8 is connected to the external thread of the threaded rod 9. The outer surface of the threaded rod 9 is provided with multiple groups of two sections of threads with opposite rotation directions. Multiple groups of clamping members are respectively distributed on the multiple groups of threads, and the two clamping plates 8 in the clamping members are symmetrically distributed on the two sections of threads with opposite rotation directions. Multiple water inlet valves are respectively placed on multiple air outlets 15. Driving the servo motor 10 can drive the threaded rod 9 to rotate. Since the clamping member is slidably connected to the inner wall of the detection box 1, the rotation of the threaded rod 9 can drive the two clamping members of the same group to slide together, and the multiple groups of clamping members can clamp and fix multiple water inlet valves at the same time.

[0025] Since the air inlet head 17 needs an air source to transport high-pressure gas to the water inlet valve, an air pump 6 is fixedly installed on one side of the top of the pressure plate 4, and air inlet pipes 7 are symmetrically arranged on the top of the pressure plate 4. The output end of the air pump 6 is connected to the two air inlet pipes 7 respectively through two conduits. The air pump 6 can be driven to transport the high-pressure gas to the pressure plate 4 through the conduits and the air inlet pipes 7. The high-pressure gas can enter the air inlet valve along the air inlet head 17, and then the detection work can be carried out.

[0026] In order to prevent the high-pressure gas from leaking from the water inlet of the water inlet valve, a hydraulic cylinder 5 is fixedly installed on the inner top wall of the slide rod 2, and the output end of the hydraulic cylinder 5 is fixedly connected to the center position of the top of the slide rod 2. The external fixed sleeve of the air inlet head 17 is provided with a sealing gasket 18. Driving the hydraulic cylinder 5 can drive the pressure plate 4 to press down, and the pressure plate 4 drives the air inlet head 17 to fit tightly with the water inlet of the water inlet valve, which can prevent the gas from leaking from the water inlet.

[0027] Since the water tank 11 is inside the detection box 1, the light inside the water tank 11 is dim, which may affect the staff's observation of the bubbles in the water tank 11. In order to solve this technical problem, lighting lamps 13 are fixedly installed on the inner walls on both sides of the water tank 11, and a box cover 12 is movably installed on the top of the water tank 11. Transparent glass is installed in the box cover 12. A drain pipe 14 is arranged on one side of the bottom of the water tank 11. The end of the drain pipe 14 passes through the detection box 1 and extends to the outside of the detection box 1. A valve is arranged on the drain pipe 14. The water in the water tank 11 can be discharged through the drain pipe 14, so that the water in the water tank 11 can be replaced regularly.

[0028] When the device is not in use, in order to prevent internal damage to the device, refer to Figure 1 As shown, a protective door 19 is symmetrically hinged on the detection box 1, and a transparent acrylic plate is installed inside the protective door 19. The protective door 19 can protect the internal parts of the equipment without affecting the staff's observation of the internal status of the equipment. The protective door 19 is provided with an embedded handle and a door suction to facilitate the opening and closing of the protective door 19.

[0029] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
