[0002] Currently, small water pumps refer to micro water pumps, micro liquid pumps, liquid sampling pumps, and diaphragm micro water pumps. Generally, small-sized micro water pumps are called micro water pumps, or colloquially, small micro water pumps. Micro water pumps have the following characteristics:

[0003] 1. Ultra-small size (smaller than the palm of your hand); unique dual-use function for water and gas, the working medium can be gas or liquid (non-oil, non-corrosive), pumping water when there is water and pumping gas when there is gas;

[0004] 2. It can operate continuously for 24 hours; long-term idling is normal and will not damage the pump.

[0005] 3. Oil-free, does not contaminate the working medium, maintenance-free, and can be installed in any direction;

[0006] 4. Applications: For pumping water-air mixtures or directly pumping water;

[0007] 5. Target customers: Water treatment, liquid sampling, scientific research, instrumentation, chemical analysis, healthcare, pharmaceuticals, bioengineering, automatic control, environmental protection and many other fields.

[0008] The related technology discloses a micro water pump testing device, referring to Figure 1 The system includes a chassis 1, a positioning device, a sealing test device 3, and a current test device 4. The positioning device includes multiple positioning blocks 2. The sealing test device 3 includes a water tank 31, a water inlet mechanism 32, and a water outlet mechanism 33. The water inlet mechanism 32 is used to transport water from the water tank 31 to the micro water pump, and the water outlet mechanism 33 is used to return water from the micro water pump to the water tank 31, thereby testing whether one end of the micro water pump leaks. The current test device 4 is installed on the chassis 1 and is used to test the stability of the current at the other end of the micro water pump.

[0009] In the process of developing this application, the inventors discovered that the technology has at least the following problems: When the above-mentioned equipment tests the micro water pump, since the sealing performance and current stability of the micro water pump are tested simultaneously, when the sealing performance of the micro water pump is not up to standard, the water inside the micro water pump will overflow during the process of the water inlet mechanism transporting water from the water tank to the inside of the micro water pump. When the overflowing water comes into contact with the current testing device, a safety accident is likely to occur, which can easily damage the equipment. Summary of the Invention

[0010] To improve the overall safety of a comprehensive testing device for micro water pumps, this application provides a comprehensive testing device for micro water pumps.

[0011] The comprehensive testing equipment for miniature water pumps provided in this application adopts the following technical solution:

[0012] A comprehensive testing device for a miniature water pump includes a chassis, on which are sequentially arranged the following:

[0013] A positioning device, comprising multiple positioning blocks, wherein each positioning block has a positioning groove for positioning a micro water pump, the depth of which is the same as the thickness of the micro water pump.

[0014] A sealing test device is used to test the sealing performance of the micro water pump;

[0015] A current testing device is used to test the stability of the current of the micro water pump;

[0016] A water-blocking and water-absorbing device is located between the sealing test device and the current test device. The water-blocking and water-absorbing device includes a support frame, an adjustment mechanism, a lifting drive mechanism, and a water-blocking plate. The support frame is fixed to the chassis, and the adjustment mechanism is disposed on the support frame. The adjustment mechanism is used to adjust the position of the lifting drive mechanism in the horizontal direction, and the lifting drive mechanism is used to drive the water-blocking plate to rise and fall. The water-blocking plate has multiple clearance grooves, and each clearance groove corresponds to a positioning device. When the water-blocking plate descends to the lowest point, the inner sidewall of the clearance groove abuts against the outer sidewall of the positioning block.

[0017] By adopting the above technical solution, since the thickness of the micro water pump is equal to the depth of the positioning groove, when the operator places multiple micro water pumps into the positioning groove in sequence, the upper surface of all micro water pumps is flush with the upper surface of the positioning block. Before testing, the position of the lifting drive mechanism is first adjusted horizontally by the adjustment mechanism. The lifting drive mechanism drives the water baffle plate to move horizontally so that the multiple clearance grooves on the water baffle plate are aligned with the multiple positioning blocks in sequence. Then, the lifting drive mechanism drives the water baffle plate to descend. When the water baffle plate descends to the lowest point, the inner wall of each clearance groove of the water baffle plate abuts against the outer wall of the positioning block. At this time, the water baffle plate separates the two ends of the micro water pump. When the water inside the micro water pump overflows, the water baffle plate blocks the overflowing water so that the overflowing water does not flow to one side of the current testing device, thus protecting the current testing device and the entire testing equipment, extending the overall service life of the testing equipment.

[0018] Optionally, the inner wall of the recess is provided with an installation groove, and a flexible absorbent material is provided in the installation groove, with the bottom of the flexible absorbent material protruding from the recess.

[0019] By adopting the above technical solution, the installation groove has a positioning function for the flexible absorbent material, increasing the efficiency of the staff in installing the flexible absorbent material onto the water-blocking plate; when the inner side wall of each clearance groove of the water-blocking plate abuts against the outer side wall of the positioning block, the water-blocking plate and the micro water pump have a squeezing effect on the flexible absorbent material. The flexible absorbent material not only has a blocking effect on the water-blocking plate and the micro water pump, thereby reducing the pressure of the water-blocking plate on the micro water pump and protecting the micro water pump; at the same time, when the micro water pump leaks water during the test, the micro water pump has an adsorption effect on the leaked water, thereby preventing the water leaking from one end of the micro water pump from flowing to one end of the current testing device.

[0020] Optionally, the adjusting mechanism includes a lead screw, an adjusting rod, and a handwheel. The support frame has an adjusting groove that extends along a first direction, and the adjusting rod slides into the adjusting groove. Both ends of the lead screw are rotatably connected to the support frame, the lead screw passes through the adjusting rod, and the lead screw is threaded into the adjusting rod. The handwheel is fixed to the end of the lead screw.

[0021] By adopting the above technical solution, the operator can rotate the screw by rotating the handwheel, which saves effort. During the rotation of the screw, the adjusting rod slides along the first direction, the adjusting rod drives the lifting drive mechanism to slide along the first direction, and the lifting drive mechanism drives the water baffle to slide along the first direction, thereby making it easier to ensure that the clearance grooves on the water baffle are aligned with the positioning blocks one by one.

[0022] Optionally, a guide rail is fixedly installed in the adjustment groove, the guide rail extends along a first direction, the guide rail passes through the adjustment rod, and the adjustment rod slides in cooperation with the guide rail.

[0023] By adopting the above technical solution, the guide rail guides the adjusting rod, increasing the stability of the adjusting rod sliding along the first direction.

[0024] Optionally, the support frame is threaded with a screw, the end of which abuts against the lead screw.

[0025] By adopting the above technical solution, when it is necessary to adjust the position of the baffle plate, the operator can rotate the screw to release the clamping effect of the screw on the baffle plate, and then it is convenient to adjust the position of the baffle plate along the first direction; after the position of the baffle plate is adjusted, the operator can rotate the screw so that the end of the screw abuts against the lead screw. At this time, the screw and the support frame have a fixing effect on the lead screw, so that the lead screw cannot be rotated, thereby fixing the baffle plate.

[0026] Optionally, a knob is fixedly installed on the screw.

[0027] By adopting the above technical solution, workers can rotate the screw by turning the knob, which saves effort.

[0028] Optionally, a fixing block is fixedly installed on the support frame, and an adjustment hole is provided on the fixing block. A bolt is inserted into the adjustment hole, and the bolt is threaded into the chassis.

[0029] By adopting the above technical solution, the bolt nut and the chassis have a clamping effect on the fixing block, thereby fixing the fixing block to the chassis, and then fixing the support frame to the chassis, which increases the convenience for workers to install and disassemble the support frame.

[0030] Optionally, the adjustment hole extends along the second direction.

[0031] By adopting the above technical solution, when the staff releases the bolts from fixing the block, it is easy to adjust the position of the support frame in the second direction, and thus easy to adjust the position of the baffle plate in the second direction.

[0032] Optionally, the sealing test device includes a water tank, at least one water inlet mechanism, at least one water outlet mechanism, and at least one return mechanism; the water tank is disposed inside the chassis, the water inlet mechanism is used to transport water in the water tank to the micro water pump, and the water outlet mechanism is used to transport water in the micro water pump to the water tank; the return mechanism includes multiple return pipes, each of which corresponds to a positioning block; each positioning slot has a through return hole at its bottom, the top end of the return pipe is fixedly connected to the bottom of the positioning block, the top end of the return pipe communicates with the return hole, and the bottom end of the return pipe passes through the water tank and communicates with the interior of the water tank.

[0033] By adopting the above technical solution, during the testing of the micro water pump's sealing performance, when there is no leakage, water from the tank is first transported to the micro water pump through the inlet mechanism, and then water from inside the micro water pump is transported back to the tank through the outlet mechanism, thus achieving water circulation. When the micro water pump leaks, the water overflowing from the micro water pump first flows to the bottom of the positioning slot under its own gravity, and then flows back to the tank through the return hole and return pipe. This ensures that the water overflowing from the micro water pump can flow back to the tank, avoiding water waste and reducing water accumulation on the surface of the positioning block, further increasing the overall safety of the comprehensive testing equipment.

[0034] Optionally, the water-proof plate is provided with multiple drying mechanisms, each corresponding to a positioning block. The drying mechanism is located above the positioning block and is used to dry the positioning block.

[0035] By adopting the above technical solution, the air-drying mechanism can dry a small amount of water on the surface of the positioning block, thereby ensuring that the positioning block can remain dry before the next test of the micro water pump.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. Since the thickness of the miniature water pump is equal to the depth of the positioning groove, when multiple miniature water pumps are placed in the positioning groove in sequence, the upper surface of all miniature water pumps is flush with the upper surface of the positioning block. Before testing, the position of the lifting drive mechanism is first adjusted horizontally by the adjustment mechanism. The lifting drive mechanism drives the water baffle plate to move horizontally so that the multiple clearance grooves on the water baffle plate are aligned with the multiple positioning blocks in sequence. Then, the lifting drive mechanism drives the water baffle plate to descend. When the water baffle plate descends to the lowest point, the inner wall of each clearance groove of the water baffle plate abuts against the outer wall of the positioning block. At this time, the water baffle plate separates the two ends of the miniature water pump. When the water inside the miniature water pump overflows, the water baffle plate blocks the overflowing water so that the overflowing water does not flow to one side of the current testing device, thus protecting the current testing device and the entire testing equipment, extending the overall service life of the testing equipment.

[0038] 2. The mounting grooves provide positioning for the flexible absorbent material, increasing the efficiency of installing it onto the baffle plate. When the inner wall of each recessed groove of the baffle plate abuts against the outer wall of the positioning block, the baffle plate and the micro pump exert a squeezing effect on the flexible absorbent material. The flexible absorbent material not only acts as a barrier against the baffle plate and the micro pump, thus reducing the pressure exerted by the baffle plate on the micro pump and protecting it, but also absorbs the leaked water during testing, preventing water leaking from one end of the micro pump from flowing onto the other end of the current testing device.

[0039] 3. When the miniature water pump leaks, the water overflowing from the miniature water pump first flows to the bottom of the positioning slot under its own gravity, and then flows back into the water tank through the return hole and return pipe. This ensures that the water overflowing from the miniature water pump can flow back into the water tank, avoiding water waste. It also reduces the amount of water accumulating on the surface of the positioning block, further increasing the overall safety of the integrated testing equipment.

[0040] 4. The air-drying mechanism has an air-drying effect on the small amount of water on the surface of the positioning block, thereby ensuring that the positioning block can remain dry before the next test of the micro water pump. Attached Figure Description

[0050] The following is in conjunction with the appendix Figure 2-7 This application will be described in further detail.

[0051] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0052] For ease of understanding, in this embodiment, the length direction of the adjusting rod 62 in the horizontal direction is defined as the first direction, and the direction perpendicular to the first direction is defined as the second direction. Based on this, the comprehensive testing equipment for the micro water pump will be described.

[0053] This application discloses a comprehensive testing device for miniature water pumps. (Refer to...) Figure 2 and Figure 3 The comprehensive testing equipment for miniature water pumps includes a chassis 1. The chassis 1 is sequentially equipped with a positioning device, a sealing performance testing device 3, a current testing device 4, and a water-blocking and suction device. The water-blocking and suction device is located between the sealing performance testing device 3 and the current testing device 4. The positioning device is used to position multiple miniature water pumps. The sealing performance testing device 3 is used to test the sealing performance of the miniature water pumps. The current testing device 4 is used to test the stability of the current of the miniature water pumps. The water-blocking and suction device is used to prevent and absorb water overflowing from the inside of the miniature water pumps. The comprehensive testing equipment for miniature water pumps has a protective function.

[0054] Reference Figure 3 and Figure 5 The positioning device includes multiple positioning blocks 2, all of which are fixed to the upper surface of the housing 1 and are evenly distributed at equal intervals along a first direction. Each positioning block 2 has a positioning groove 21 on its upper surface for positioning the micro water pump; the depth of the positioning groove 21 is the same as the thickness of the micro water pump. After the operator places the micro water pump into the positioning groove 21, the upper surface of the micro water pump is flush with the upper surface of the positioning block 2.

[0055] Reference Figure 3 and Figure 4The sealing performance testing device 3 is used to test the sealing performance of the micro water pump. The sealing performance testing device 3 includes a water tank 31, at least one inlet mechanism 32, at least one outlet mechanism 33, and at least one return mechanism. The inlet mechanism 32, outlet mechanism 33, and return mechanism correspond one-to-one. The water tank 31 is located inside the casing 1. The inlet mechanism 32 is used to transport water from the water tank 31 to the micro water pump, and the outlet mechanism 33 is used to transport water from the micro water pump to the water tank 31. The return mechanism includes multiple return pipes 34, each corresponding to a positioning block 2. Each positioning slot 21 has a through return hole 22 at its bottom. The top end of the return pipe 34 is fixedly connected to the bottom of the positioning block 2, and the top end of the return pipe 34 communicates with the return hole 22. The bottom end of the return pipe 34 passes through the water tank 31 and communicates with the interior of the water tank 31. During the testing of the micro water pump's sealing performance, when the micro water pump does not leak, water is first transported from the water tank 31 to the micro water pump through the water inlet mechanism 32, and then water from inside the micro water pump is transported back to the water tank 31 through the water outlet mechanism 33, thus achieving water circulation. When the micro water pump leaks, the water overflowing from the micro water pump first flows to the bottom of the positioning groove 21 under its own gravity, and then flows back to the water tank 31 through the return hole 22 and the return pipe 34. This ensures that the water overflowing from the micro water pump can flow back to the water tank 31, avoiding water waste and reducing water accumulation on the surface of the positioning block 2, further increasing the overall safety of the integrated testing equipment.

[0056] Continue to refer to Figure 3 The current testing device 4 is set on the surface of the chassis 1, and the positioning device is located between the sealing testing device 3 and the current testing device 4. The current testing device 4 is used to test the stability of the current of the micro water pump.

[0057] Reference Figure 5 and Figure 6 The water-blocking and water-absorbing device includes a support frame 5, an adjusting mechanism 6, a lifting drive mechanism 7, and a water-blocking plate 8. The support frame 5 is fixed to the upper surface of the housing 1. The adjusting mechanism 6 is disposed on the support frame 5 and is used to adjust the position of the lifting drive mechanism 7 in the horizontal direction. The lifting drive mechanism 7 is used to drive the water-blocking plate 8 to rise and fall. In this embodiment, the lifting drive mechanism 7 is a cylinder. The water-blocking plate 8 has multiple clearance grooves 81, which correspond one-to-one with the positioning blocks 2. When the water-blocking plate 8 descends to the lowest point, the inner wall of the clearance groove 81 abuts against the outer wall of the positioning block 2.

[0058] Reference Figure 4 and Figure 5Since the thickness of the miniature water pump is equal to the depth of the positioning groove 21, when the operator places multiple miniature water pumps into the positioning groove 21 in sequence, the upper surface of all the miniature water pumps is flush with the upper surface of the positioning block 2. Before testing, the position of the lifting drive mechanism 7 is first adjusted horizontally by the adjusting mechanism 6. The lifting drive mechanism 7 drives the water baffle 8 to move horizontally so that the multiple clearance grooves 81 on the water baffle 8 are respectively aligned with the multiple positioning blocks 2 in sequence. Then, the lifting drive mechanism 7 drives the water baffle 8 to descend. When the water baffle 8 descends to the lowest point, the inner sidewall of each clearance groove 81 of the water baffle 8 abuts against the outer sidewall of the positioning block 2. At this time, the water baffle 8 separates the two ends of the miniature water pump. When the water inside the miniature water pump overflows, the water baffle 8 blocks the overflowing water so that the overflowing water does not flow to one side of the current testing device 4, thus protecting the current testing device 4 and the entire testing equipment, extending the overall service life of the testing equipment (in conjunction with...). Figure 3 ).

[0059] Reference Figure 5 A fixing block 55 is fixedly installed on the support frame 5. The fixing block 55 has an adjustment hole 56 extending in the second direction. A bolt passes through the adjustment hole 56 and is threaded into the housing 1. The bolt nut and the housing 1 clamp the fixing block 55, thereby fixing the fixing block 55 to the housing 1, and consequently fixing the support frame 5 to the housing 1, increasing the convenience of installation and disassembly of the support frame 5. When the bolt is released from its fixing effect on the fixing block 55, the position of the support frame 5 can be easily adjusted in the second direction, and consequently, the position of the baffle plate 8 can be easily adjusted in the second direction.

[0060] Reference Figure 6 The adjusting mechanism 6 includes a lead screw 61, an adjusting rod 62, and a handwheel 63. A through adjusting groove 51 is formed on the upper surface of the support frame 5, extending along a first direction. Both ends of the adjusting groove 51 are closed. The length of the adjusting rod 62 is less than the length of the adjusting groove 51, and the adjusting rod 62 slides into the adjusting groove 51. The lead screw 61 extends along the first direction, with both ends passing through the support frame and rotatably connected to both ends of the lead screw 61. The lead screw 61 passes through the adjusting rod 62, and the lead screw 61 and adjusting rod 62 are threaded together. The handwheel 63 is fixed to one end of the lead screw 61. The operator rotates the handwheel 63 to rotate the lead screw 61, which saves effort. During rotation, the lead screw 61 drives the adjusting rod 62 to slide along the first direction. The adjusting rod 62 drives the lifting drive mechanism 7 to slide along the first direction, and the lifting drive mechanism 7 drives the water-blocking plate 8 to slide along the first direction, thus ensuring that the clearance grooves 81 on the water-blocking plate 8 are aligned with the positioning blocks 2.

[0061] Reference Figure 6Guide rails 52 are fixedly installed on both opposite sides of the adjusting groove 51. Both guide rails 52 extend along the first direction and pass through the adjusting rod 62. The adjusting rod 62 slides in conjunction with the two guide rails 52. The two guide rails 52 guide the adjusting rod 62, increasing the stability of the adjusting rod 62 sliding along the first direction.

[0062] Reference Figure 5 and Figure 6 A screw 53 is threaded onto the support frame 5, with the end of the screw 53 abutting against the lead screw 61. When the position of the baffle plate 8 needs to be adjusted, the operator can rotate the screw 53 to release its clamping effect on the baffle plate 8, thus facilitating adjustment of the baffle plate 8 along the first direction. After the position of the baffle plate 8 is adjusted, the operator rotates the screw 53 so that its end abuts against the lead screw 61. At this point, the screw 53 and the support frame 5 fix the lead screw 61, preventing it from rotating and thus securing the baffle plate 8. A knob 54 is fixedly installed on the screw 53. The operator rotates the knob 54 to rotate the screw 53, which saves effort.

[0063] Reference Figure 7 The inner wall of the recess 81 is provided with an installation groove 82, and a flexible absorbent material 83 is provided in the installation groove 82. The bottom of the flexible absorbent material 83 protrudes from the recess 81. The installation groove 82 has a positioning function for the flexible absorbent material 83, which increases the efficiency of the operator in installing the flexible absorbent material 83 on the water-blocking plate 8. When the inner wall of each recess 81 of the water-blocking plate 8 abuts against the outer wall of the positioning block 2, the water-blocking plate 8 and the micro water pump have a squeezing effect on the flexible absorbent material 83. The flexible absorbent material 83 not only has a blocking effect on the water-blocking plate 8 and the micro water pump, thereby reducing the pressure of the water-blocking plate 8 on the micro water pump, but also has a protective effect on the micro water pump. At the same time, when the micro water pump leaks water during the test, the micro water pump has an adsorption effect on the leaked water, thereby preventing the water leaking from one end of the micro water pump from flowing to one end of the current testing device 4.

[0064] Reference Figure 5 and Figure 7 Multiple drying mechanisms 9 are provided on the water-separating plate 8, evenly distributed at equal intervals along a first direction. Each drying mechanism 9 corresponds to a positioning block 2 and is located above the positioning block 2. The drying mechanism 9 is used to dry the positioning block 2. Each drying mechanism 9 includes a mounting block 91 and at least one hot air blower 92. The mounting block 91 is fixed to the side wall of the water-separating plate 8, and the hot air blower is fixed to the lower surface of the mounting block 91. The drying mechanism 9 dries a small amount of water on the surface of the positioning block 2, thereby ensuring that the positioning block 2 remains dry before the next test of the micro water pump.

[0065] Reference Figure 1A protective cover 10 is fixedly installed on the upper surface of the chassis 1. The sealing test device 3 is located inside the protective cover 10. The protective cover 10 protects the sealing test device 3 and increases the cleanliness of the surface of the sealing test device 3.

[0066] The implementation principle of the above embodiment is as follows: Since the thickness of the micro water pump is equal to the depth of the positioning groove 21, when the operator places multiple micro water pumps into the positioning groove 21 in sequence, the upper surface of all micro water pumps is flush with the upper surface of the positioning block 2. Before testing, the position of the lifting drive mechanism 7 is first adjusted horizontally by the adjustment mechanism 6. The lifting drive mechanism 7 drives the water baffle 8 to move horizontally so that the multiple clearance grooves 81 on the water baffle 8 are respectively aligned with the multiple positioning blocks 2 in sequence. Then, the lifting drive mechanism 7 drives the water baffle 8 to descend. When the water baffle 8 descends to the lowest point, the inner sidewall of each clearance groove 81 of the water baffle 8 abuts against the outer sidewall of the positioning block 2. At this time, the water baffle 8 separates the two ends of the micro water pump. When the water inside the micro water pump overflows, the water baffle 8 blocks the overflowing water so that the overflowing water does not flow to one side of the current testing device 4, thereby protecting the current testing device 4 and the entire testing equipment, thus extending the overall service life of the testing equipment.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
