[0002] With the continuous improvement of people's living standards, water-storage devices such as instant hot water dispensers, coffee machines, and humidifiers are becoming increasingly popular, enhancing people's quality of life. These devices are equipped with water tanks to supply water, and these tanks typically feature a check valve for water supply and a float for water level detection. The quality of the water tank is crucial to the overall performance of the device, making its factory quality critical. Currently, manufacturers manually inspect the water tank's components, checking for openability and airtightness of the check valve, as well as the movement of the float. However, manual inspection is inefficient, and workers are prone to fatigue over long periods. This high-intensity fatigue can lead to misjudgments, significantly impacting the accuracy of the inspection. Summary of the Invention

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown, the present invention provides a water storage tank testing device, which includes a machine base 1, a fixture seat 11 disposed on the machine base 1, a clamping platform 12 movably disposed on the fixture seat 11, a clamping device 2 disposed on the clamping platform 12, an inflation device 3 disposed on the fixture seat 11, and an air tightness testing device 4 disposed on the fixture seat 11 for testing the air tightness of the check valve 131 of the water storage tank 13. The air tightness testing device 4 includes a sealing rod slidably disposed on the fixture seat 11, a pressure sensor connected to the sealing rod, and a first driving device for driving the sealing rod to move. The inflation device 3 includes a moving rod 31 slidably disposed on the fixture seat 11, an inflation component 32 disposed on the moving rod 31, and a second driving device 33 for driving the moving rod 31 to move.

[0027] In practical applications, the top of the water tank 13 is open to allow water to enter from the outside. The bottom or side of the water tank 13 is equipped with a check valve 131 for connecting to external devices (such as coffee machines, water dispensers, and humidifiers). When the check valve 131 is open, water from the water tank 13 flows into the device; when the check valve 131 is closed, it stops the flow of water from the water tank 13 into the device. The check valve 131 includes an inlet 136, a valve 134, and a sealing port 133 (i.e., an outlet). The valve 134 is controlled by the elasticity of a spring 135 to open and close the sealing port 133. When the water tank 13 testing equipment is working, the clamping device is used to clamp the water tank 13 onto the clamping platform 12. The clamping platform 12 moves the water tank 13 until the sealing port 133 of the check valve 131 of the water tank 13 is aligned with the sealing rod, and the water inlet 136 of the check valve 131 is aligned with the air filling component 32. Next, after the water tank 13 is positioned, the first drive device drives the sealing rod to move so that the sealing rod contacts the sealing port 133 and seals it; then, the second drive device 33 drives the inflation component 32 to move so that the inflation component 32 enters the inlet 136 of the check valve 131. After the inflation component 32 enters the inlet 136, it inflates the inside of the check valve 131; after the check valve 131 is inflated, the sealing rod located at the sealing port 133 receives the pressure of the gas. This pressure is transmitted to the pressure sensor, which then sends a pressure signal to the computer electrically connected to it. The computer reads the corresponding pressure value and uses the pressure value to determine whether the check valve 131 can reach the pressure value for sealing. If the pressure value is too low, the check valve 131 of the water tank 13 fails to achieve the sealing function, and the water tank 13 is a defective product. This invention uses a clamping platform 12 to fix the water storage tank 13 and move it to the testing station. Then, a sealing rod is used to seal the check valve 131 of the water storage tank 13, while an inflation device 32 inflates the check valve 131. Finally, a pressure sensor detects the pressure received by the sealing rod after the check valve 131 is inflated. The test data is used to determine whether the water storage tank 13 is a qualified product. This invention uses the clamping platform 12, the airtightness testing device 4, and the inflation device 3 to automate the testing of the water outlet seal of the water storage tank 13, replacing existing manual testing methods. This avoids subjective misjudgment by workers, greatly improves the accuracy of the water storage tank 13 testing, increases the efficiency of the water storage tank 13's production, and significantly reduces labor costs.

[0028] In this technical solution, the water storage tank 13 detection device further includes an elasticity detection device 5. The elasticity detection device 5 includes a top rod 51 movably mounted on the clamp seat 11. The top rod 51 is connected to a pressure sensor. The first driving device is drivenly connected to the top rod 51 and is used to drive the top rod 51 to move.

[0029] In practical applications, the valve 134 of the check valve 131 is reset by the elastic force of the spring 135. The elastic force keeps the valve 134 pressed against the sealing port 133, thereby blocking the water flow. Whether the elastic force meets the standard is also a criterion for judging whether the water storage tank 13 is a good product; therefore, it is particularly important to test the elastic force of the spring 135. In this technical solution, after the check valve 131 of the water storage tank 13 completes the sealing test, the sealing rod retracts. Then, the first driving device drives the push rod 51 to move into the sealing port 133 of the check valve 131, contacting the valve 134 and pushing the valve 134 away from the sealing port 133. At this time, the valve 134 compresses the spring 135, and the elastic force of the spring 135 is transmitted to the pressure sensor through the push rod 51. The pressure sensor then sends a pressure signal to the computer electrically connected to it. The computer reads the corresponding pressure value and uses the pressure value to determine whether the elastic force of the spring 135 of the check valve 131 meets the factory standard. If the elastic force is too small, it means that the sealing force of the valve 134 is not large enough and the sealing performance does not meet the standard. Specifically, the elastic force of the spring 135 can be tested in both the non-inflated and inflated states of the check valve 131. When testing in the inflated state, its inflation pressure can be consistent with the pressure state of the water storage tank 13 after water is filled.

[0030] In this technical solution, the first driving device includes a fixed base 431 disposed on the clamp seat 11, a sliding block 432 slidably disposed on the fixed base 431, a moving driving member 433 disposed on the fixed base 431, and a rotary driving mechanism disposed on the sliding block 432. The pressure sensor is disposed on the sliding block 432 and connected to the sealing rod and the top rod 51. The sealing rod and the top rod 51 are disposed side by side on the sliding block 432. The rotary driving mechanism is used to drive the sealing rod and the top rod 51 to rotate on the sliding block 432. In this technical solution, the moving drive component 433 is used to drive the sliding block 432 to move closer to or further away from the fixture seat 11; after the airtightness test is completed, the moving drive component 433 drives the sealing rod to exit the sealing port 133 and reset, and then the rotation drive mechanism drives the sealing rod and the top rod 51 to rotate side by side, and after rotating 180 degrees, the position of the top rod 51 is aligned with the position of the sealing port 133; then, the moving drive component 433 drives the top rod 51 to move and extend into the sealing port 133 to contact the valve 134, and compress the spring 135 of the valve 134, thereby detecting the elastic force of the spring 135.

[0031] In this embodiment, the rotary drive mechanism includes a first fixed block 434 mounted on the pressure sensor, a rotary drive component 435 mounted on the first fixed block 434, and a rotary block 436 mounted on the first fixed block 434. The rotary drive component 435 is drivably connected to the rotary block 436. The sealing rod and the top rod 51 are connected side-by-side to the rotary block 436. Specifically, the rotary drive component 435 is a rotary cylinder, whose rotation shaft is connected to the rotary block 436. The cylinder body is connected to the pressure sensor, which is mounted on a sliding block 432. In practical applications, the rotary drive component 435 drives the rotary block 436 to rotate, thereby causing the top rod 51 and the sealing rod to rotate synchronously. This structure is simple and compact, allowing the same pressure sensor to be used for testing the top rod 51 and the sealing rod, saving costs.

[0032] In this technical solution, the clamping table 12 includes a carrying plate 121 and flipping blocks 122 respectively disposed on both sides of the carrying plate 121. The flipping blocks 122 are rotatably connected to the clamping seat 11. The clamping seat 11 is provided with a rotation drive device 123 for driving the flipping blocks 122 to rotate. The clamping device 2 is disposed at the end of the flipping blocks 122 away from the carrying plate 121. The inflation device 3 is installed at the bottom of the clamping seat 11. The air tightness detection device 4 and the elasticity detection device 5 are installed on one side of the clamping seat 11 and located above the clamping seat 11. In this embodiment, the rotation drive device 123 includes a rotating fixed seat disposed on the clamping seat 11 and a drive motor disposed on the rotating fixed seat. The output shaft of the drive motor is connected to the flipping blocks 122. In practical applications, the water tank 13 to be tested is placed and fixed on the carrier plate 121 with its opening facing upwards (i.e., the bottom of the water tank 13 rests on the carrier plate 121). Then, the clamping device 2 clamps the water tank 13 on the carrier plate 121 to ensure that the water tank 13 is stably fixed on the carrier plate 121. During operation, the rotating drive device 123 drives the flipping block 122 to flip. The flipping of the flipping block 122 causes the carrier plate 121 to flip 180 degrees. After the carrier plate 121 flips, it also causes the water tank 13 to flip, so that the opening of the water tank 13 faces downwards. At this time, the check valve 131 at the bottom of the water tank 13 corresponds to the position of the airtightness testing device 4 and the elasticity testing device 5. During testing, the inflation component 32 of the inflation device 3, driven by the second drive device 33, extends from the opening of the water storage tank 13 into the water tank and enters the inlet 136 of the check valve 131. Then, the airtightness testing device 4 and the spring force testing device 5 test the sealing of the check valve 131 and the spring force of the spring 135 inside the valve 134. The working principle has been described above and will not be repeated here. This structural design allows the entire testing equipment to be more compact and its mechanical operation to be faster and simpler.

[0033] In this embodiment, the clamping device 2 includes a pressing block 21 movably mounted on the clamping table 12 and a pressing drive device 22 for driving the pressing block 21. In practical applications, after the carrier plate 121 is placed on the carrier plate 121, the pressing drive device 22 drives the pressing block 21 to move until the pressing block 21 presses and fixes the water storage tank 13 onto the carrier plate 121. The movement of the pressing block 21 can be varied, such as rotation or movement. Specifically, the pressing drive device 22 includes a pressing cylinder mounted on the tilting block 122, the pressing block 21 is connected to the telescopic rod of the pressing cylinder, and the pressing block 21 is horizontally mounted on the carrier plate 121. In practical applications, the pressing block 21 is located on the side away from the carrier plate 121. After the water tank 13 is placed on the carrier plate 121, the pressing cylinder drives the pressing block 21 to move closer to the carrier plate 121 until the pressing block 21 contacts the open end of the water tank 13 and is pressed.

[0034] In this technical solution, the clamping platform 12 is equipped with a buoy detection device for detecting changes in the position of the buoy within the water storage tank 13. The buoy detection device includes a second fixing block 71 mounted on the loading plate 121, a first buoy sensor 72 mounted on the second fixing block 71, and a second buoy sensor 73 mounted on the second fixing block 71. The second fixing block 71 is vertically mounted on the loading plate 121. The first buoy sensor 72 and the second buoy sensor 73 are vertically spaced apart, with the first buoy sensor 72 located closer to the loading plate 121 and the second buoy sensor 73 located above the first buoy sensor 72. In practical applications, a buoy block that can move up and down is provided at the bottom of the water storage tank 13. The buoy block contains a magnetic block, and both the first buoy sensor 72 and the second buoy sensor 73 are magnetic sensors. When the water tank 13 is placed on the loading plate 121, the loading plate 121 is not flipped. The position of the buoy block of the water tank 13 is aligned with the position of the first buoy sensor 72. Thus, the first buoy sensor 72 senses and records the buoy block. Then, when the loading plate 121 is flipped, the first buoy sensor 72 and the second buoy sensor 73 flip along with the loading plate 121. At this time, the buoy block of the water tank 13 moves downward and moves to the position corresponding to the second buoy sensor 73. Thus, the second buoy sensor 73 senses and records the buoy block. By detecting the two positions of the buoy block by the first buoy sensor 72 and the second buoy sensor 73 respectively, it is determined whether the buoy block is moving normally, and thus whether the buoy of the water tank 13 can work normally.

[0035] In this technical solution, the second fixing block 71 is slidably mounted on the material carrier plate 121. The second fixing block 71 is equipped with a third driving device 74 for driving the second fixing block 71 closer to or further away from the clamping platform 12. Specifically, the third driving device 74 is a driving cylinder, and the second fixing block 71 is connected to the telescopic rod of the driving cylinder. In practical applications, when it is necessary to detect the buoy block, the third driving device 74 drives the second fixing block 71, along with the first buoy sensor 72 and the second buoy sensor 73, to move closer to the water storage tank 13, so that the first buoy sensor 72 and the second buoy sensor 73 can detect the buoy block. After detection, the third driving device 74 drives the second fixing block 71, along with the first buoy sensor 72 and the second buoy sensor 73, to reset. In this embodiment, since the first buoy sensor 72 and the second buoy sensor 73 are detected by magnetic detection of the buoy block, if the first buoy sensor 72 and the second buoy sensor 73 are not far away from the water tank 13, they will be magnetically attracted and unable to move after the water tank 13 is flipped.

[0036] In this technical solution, a rib detection device 6 is provided on the fixture base 11. The rib detection device 6 includes a touch sensing block 61 slidably disposed on the fixture base 11 and a fourth driving device 62 for driving the touch sensing block 61 to slide. The touch sensing block 61 is located on one side of the clamping table 12. Specifically, the fourth driving device 62 is a driving cylinder, and the touch sensing block 61 is connected to the extension rod of the driving cylinder. In practical applications, a rib 132 is provided on one side of the water storage tank 13. In order to detect whether this rib 132 of the water storage tank 13 meets the standard, the rib detection device 6 is used to detect the position of the rib 132. During operation, after the water tank 13 is placed on the loading plate 121, the fourth drive device 62 drives the touch sensor block 61 to move towards the side of the water tank 13. When it moves to the preset position, the touch sensor block 61 will contact the rib plate 132 of the water tank 13. At this time, the rib plate 132 of the water tank 13 is in compliance with the standard. If the touch sensor block 61 does not contact the rib plate 132 of the water tank 13 when it moves to the preset position, then the rib plate 132 of the water tank 13 is judged to be non-compliant and is a defective product.
