Description

Faucet Leak Detection Device Technical Field

[0001] This application relates to the technical field of faucet detection, and in particular to a faucet leakage detection device. Background Technology

[0002] Faucets are extremely common water-using devices in industrial production and daily life, widely used in various places. With social development, people's requirements for the quality and performance of faucets are constantly increasing, especially the sealing performance, which directly affects the rational use of water resources and the user experience. Ensuring that faucets do not leak not only avoids water waste but also reduces a series of problems that leaks may cause, such as furniture damage and floor soaking. Therefore, faucet leak detection has become increasingly important. Accurate and effective leak detection helps improve product quality, enhances consumer satisfaction, and ultimately drives the entire faucet industry towards higher quality and more environmentally friendly development.

[0003] In the past, to detect whether a faucet was leaking, workers would hold the faucet and connect the water supply pipe to the faucet's inlet, then manually observe whether there was water seepage on the faucet's surface. The connection of the water supply pipe was cumbersome and affected the efficiency of the test. Summary of the Invention

[0004] To simplify the connection between the water supply pipe and the faucet inlet and improve detection efficiency, this application provides a faucet leakage detection device.

[0005] The faucet leakage detection device provided in this application adopts the following technical solution:

[0006] A faucet leakage detection device includes a frame and a water supply mechanism. The water supply mechanism includes a connecting pipe connected to the frame. The upper end of the connecting pipe is used to connect to the water inlet of the faucet to be tested. There are two connecting pipes, which are distributed horizontally at intervals. The lower ends of the two connecting pipes are respectively connected to an external hot water source or a cold water source through pipes.

[0007] By adopting the above technical solution, the faucet to be tested is connected to two connecting pipes, so that the two connecting pipes are connected to the hot and cold water inlets of the faucet to be tested. Hot water and cold water from the outside are respectively introduced into the connecting pipes and then sent into the faucet to be tested to observe whether the faucet is leaking. This simplifies the operation of connecting the water supply pipe to the faucet inlet and improves the testing efficiency.

[0008] Preferably, it also includes a second fixing bolt. The frame is connected to a mounting base. The mounting base has a second connecting hole. The number of the second connecting holes is the same as the number of connecting pipes and they correspond one-to-one. The connecting pipes are coaxially slidably embedded in the second connecting holes. The side wall of the mounting base has a second mounting hole. The second mounting hole communicates with the second connecting hole. The number of the second mounting hole and the second fixing bolt is the same as the number of the second connecting hole and they correspond one-to-one. The second fixing bolt is threadedly connected to the second mounting hole and abuts against the side wall of the connecting pipe.

[0009] By adopting the above technical solution, the second fixing bolt and the second mounting hole abut against the outer wall of the connecting pipe, thereby achieving a fixed connection between the connecting pipe and the frame. The relative fixation of the connecting pipe can be adjusted as needed to meet the testing needs of different models of faucets and improve the applicability of the equipment.

[0010] Preferably, the device further includes a positioning component. The frame is connected to a placement seat, which is located above the mounting base. The upper end of the placement seat has a placement groove for the lower end of the faucet to be tested to be embedded in. The bottom of the placement groove has a first connecting hole, the number of which is the same as the number of connecting pipes and corresponds one-to-one. The first connecting hole is for the connecting pipes to pass through. The positioning component includes a positioning plate and a positioning drive cylinder. The positioning plate is slidably connected to the frame, and the sliding direction of the positioning plate is vertical. The positioning plate is used to press against the upper end of the faucet to be tested. The positioning drive cylinder is connected to the frame and is used to drive the positioning plate to slide.

[0011] By adopting the above technical solution, the positioning drive cylinder drives the positioning plate to press against the upper end of the faucet to be tested, and the positioning plate and the placement seat clamp the faucet to be tested, reducing the possibility of the faucet to be tested moving vertically during the testing process and improving the reliability of the equipment testing.

[0012] Preferably, the positioning plate has a connecting hole for the operation button at the top of the faucet to be tested to pass through, and the wall of the connecting hole fits against the outer wall of the top of the faucet to be tested.

[0013] By adopting the above technical solution, the positioning plate is provided with a connecting hole, through which the operation button of the water faucet passes, making it convenient for the staff to adjust the operation button to connect the two flow channels to the connecting pipes respectively, so that the detection of the two flow channels can be achieved at one time, improving the convenience of equipment operation and detection efficiency.

[0014] Preferably, the positioning assembly further includes a sliding seat and a first fixing bolt. The sliding seat is slidably connected to the frame, and the sliding direction of the sliding seat is vertical. The sliding seat is provided with a first mounting groove. One end of the positioning plate is slidably embedded in the first mounting groove, and the sliding direction of the positioning plate is horizontal. The side wall of the positioning plate is in contact with the groove wall of the first mounting groove. The upper end of the sliding seat is provided with a first mounting hole, and the first mounting hole is connected to the first mounting groove. The first fixing bolt is threadedly connected to the first mounting hole and abuts against the positioning plate.

[0015] By adopting the above technical solution, the positioning drive cylinder drives the sliding seat to slide, which in turn drives the positioning plate to slide against the faucet to be tested. The positioning plate can be replaced or the relative position of the positioning plate and the sliding seat can be adjusted as needed to adapt to different models of faucets to be tested, thereby improving the applicability of the equipment.

[0016] Preferably, the water supply mechanism further includes a sealing ring bladder, a compression air bladder, a sliding plate, and a first reset member. Two sealing ring bladders are provided, each connected to the outer periphery of the upper end of two connecting pipes. The compression air bladders are connected to the frame, and the number of compression air bladders is the same as the number of sealing ring bladders, with each compression air bladder connected to one of the two sealing ring bladders via a pipe. The sliding plate is slidably connected to the frame, and the sliding direction of the sliding plate is vertical. The sliding plate is used to abut against the upper end of the positioning plate. The first reset member is connected between the sliding plate and the frame, and the first reset member causes the sliding plate to tend to abut against the compression air bladder.

[0017] By adopting the above technical solution, when the lower end of the positioning plate abuts against the water tap to be tested, the sliding plate abuts against the squeezing airbag under the elastic force of the first reset component, and the gas in the squeezing airbag is forced into the sealing airbag through the pipe. The sealing airbag expands and presses against the inner wall of the water inlet of the water tap to be tested, thereby improving the sealing performance between the connecting pipe and the water tap to be tested and improving the reliability of the equipment.

[0018] Preferably, the water supply assembly further includes a first solenoid valve, a contact switch, a slider, a second reset element, and a push ring. The number of the push ring, the first solenoid valve, the contact switch, and the slider corresponds one-to-one with the number of connecting pipes. The first solenoid valve is connected to the end of the connecting pipe away from the faucet being tested to achieve the opening and closing of the connecting pipe. The contact switch is connected to the frame and is electrically connected to the first solenoid valve. When the contact switch is closed, the first solenoid valve is open. The slider is slidably connected to the frame and is used to abut against the contact switch. The second reset element is connected between the slider and the frame, and the second reset element causes the slider to tend to move away from the contact switch. The push ring is connected to the frame and is connected to the sealing ring through a pipe. The push ring is used to push the slider to slide closer to the contact switch.

[0019] By adopting the above technical solution, when the sealing ring bladder is in normal use, the gas in the squeeze bladder enters the sealing ring bladder, driving it to expand. This gas then enters the push bladder, driving it to expand as well. The push bladder then pushes the slider against the contact switch, overcoming the spring of the second reset element. The contact switch closes, and the first solenoid valve opens, allowing water to be supplied to the faucet under test via the connecting pipe for detection. When the sealing ring bladder leaks, it cannot press tightly against the inner wall of the faucet's inlet. Liquid entering the faucet leaks through the gap between the connecting pipe and the inner wall of the faucet's inlet. The liquid embedded in the squeeze bladder leaks from the sealing ring bladder cavity, preventing the push bladder from driving the slider to close the contact switch. The first solenoid valve remains closed, improving the reliability of the equipment and the accuracy of the test results.

[0020] Preferably, the device further includes a clamping assembly, which comprises a clamping block, a first gear, a first rack, and a clamping drive cylinder. The clamping block is slidably connected to the upper end of the placement seat, and the sliding direction of the clamping block is horizontal. There are two clamping blocks, which are symmetrically distributed along the sliding direction of the clamping blocks. One end of the clamping block near the other clamping block abuts against the outer wall of the lower end of the faucet to be tested. The clamping drive cylinder is connected to the placement seat and is used to drive the clamping block to slide. The first gear is rotatably connected to the placement seat, and the rotation axis of the first gear is perpendicular to the sliding direction of the clamping block. There are two first racks, one end of each of the two first racks is connected to the two clamping blocks respectively, and the first racks mesh with the first gear.

[0021] By adopting the above technical solution, the clamping drive cylinder drives two clamping blocks to clamp the outer wall of the lower end of the faucet under test, reducing the possibility of the faucet under test moving horizontally during the test and improving the reliability of the equipment test.

[0022] Preferably, one end of the clamping block near the other clamping block is provided with a V-shaped groove, and the groove wall of the V-shaped groove is used to press against the outer wall of the lower end of the faucet to be tested.

[0023] By adopting the above technical solution, the clamping block is equipped with a V-groove to accommodate faucets of different sizes to be tested, thereby improving the applicability of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Connect the faucet to be tested to two connecting pipes, so that the two connecting pipes are connected to the hot and cold water inlets of the faucet. Insert hot and cold water from the outside into the connecting pipes and then into the faucet to observe whether the faucet is leaking. This simplifies the operation of connecting the water supply pipe to the faucet inlet and improves the testing efficiency.

[0026] 2. The positioning drive cylinder drives the positioning plate to press against the upper end of the faucet to be tested. The positioning plate and the placement seat clamp the faucet to be tested, reducing the possibility of the faucet to be tested moving vertically during the test and improving the reliability of the equipment test.

[0027] 3. When the lower end of the positioning plate abuts against the faucet to be tested, the sliding plate abuts against the compression airbag under the elastic force of the first reset component, and the gas in the compression airbag is forced into the sealing airbag through the pipe. The sealing airbag expands and presses against the inner wall of the water inlet of the faucet to be tested, thereby improving the sealing performance between the connecting pipe and the faucet to be tested and improving the reliability of the equipment.

[0046] The implementation principle of a faucet leakage detection device in this application embodiment is as follows: the lower end of the faucet to be tested is embedded in the placement groove 151, the upper end of the connecting pipe 22 and the sealing ring 23 are embedded in the water inlet of the faucet to be tested, the piston rod of the clamping drive cylinder 312 extends, pushing the two clamping blocks 311 to move closer to each other, and the groove walls of the two V-shaped grooves 3111 abut against the outer wall of the lower end of the faucet to be tested.

[0047] The piston rod of the positioning drive cylinder 324 retracts, causing the sliding seat 321 to move downwards, which in turn moves the positioning ring downwards to abut the upper end of the faucet under test, allowing the operating button at the upper end of the faucet to pass through the connecting hole 3231. The sliding plate 25, under the elastic force of the first reset member 26, presses against the compression airbag 24, forcing the gas inside the compression airbag 24 through a pipe into the sealing ring bladder 23. The sealing ring bladder 23 expands and presses against the inner wall of the faucet's inlet. The gas then enters the pushing airbag 211 through a pipe, pushing the airbag 211 to expand and push the slider 29 to slide. The slider 29 abuts against the contact switch 28, closing the contact switch 28 and opening the first solenoid valve 27. Operating the corresponding control valve 21 connects the connecting pipe 22 to an external cold or hot water source, allowing for testing of the corresponding pipeline.

[0048] After the test is completed, all control valves 21 are closed. The piston rod of the positioning drive cylinder 324 extends, causing the sliding seat 321 to move upward, which in turn causes the positioning plate 323 to move upward. The positioning plate 323 abuts against the sliding plate 25, pushing the sliding plate 25 away from the compression airbag 24. The slider 29 extends out of the slide groove 155 under the action of the elastic force of the second reset member 210. The contact switch 28 is opened, and the first solenoid valve 27 is closed. The cylinder and sealing ring bladder 23 are pushed to contract, pushing the gas in the airbag 211 and sealing ring bladder 23 back into the compression airbag 24 through the pipe. The piston rod of the clamping drive cylinder 312 contracts, causing the two clamping blocks 311 to move away from each other.
