DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described below in conjunction with the embodiments and drawings.

The terms "first" and "second" are used solely for the purpose of distinguishing technical features and are not to be construed as indicating or implying relative importance, or as implicitly indicating the number of technical features indicated, or as implicitly indicating the order of the technical features indicated. Furthermore, "and / or" appearing throughout the text represent three parallel solutions. For example, "A and / or B" represents a solution where A satisfies, a solution where B satisfies, or a solution where both A and B satisfy.

[0047] In the description of the present invention, the terms "comprises", "includes" or any other variations thereof are intended to cover a non-exclusive inclusion, which may include not only the listed elements but also other elements not explicitly listed.

[0048] As described in the background technology, the use of pulse solenoid valves will be affected by the application environment, and most of the existing aging tests directly control the opening and closing of the pulse solenoid valves through a controller, resulting in a low simulation degree of the test device, affecting the accuracy of the aging test and causing the water flow of the applied induction faucet to be unstable.

[0049] Based on this, an embodiment of the present invention proposes an aging test device for a pulse solenoid valve to improve the simulation degree of the test device and the accuracy of the aging test, and to improve the stability of the water flow rate of the applied induction faucet.

[0050] like Figures 1 to 3 As shown, the aging test device for the pulse solenoid valve provided by some embodiments of the present invention includes: a flushing pipeline 100 , a flow meter 300 , a control module 400 and a water supply module 500 .

[0051] One end of the flushing pipe 100 is connected to the pulse solenoid valve 200, which is fixed to one end of the flushing pipe 100. The pulse solenoid valve 200 is electrically connected to the output end of the control module 400, which controls the opening and closing of the pulse solenoid valve 200.

[0052] The flow meter 300 is provided on the flushing pipe 100 and is electrically connected to the input end of the control module 400 . The flow meter 300 detects the flushing water volume in the flushing pipe 100 and sends the flushing water volume to the control module 400 .

[0053] The output end of the water supply module 500 is communicated with the other end of the flushing pipe 100 . The water supply module 500 is electrically connected to the control module 400 . The water supply module 500 delivers water to the flushing pipe 100 .

[0054] In one embodiment, the control module 400 outputs a control signal to control the measured pulse solenoid valve 200 to open, causing the constant pressure water tank 520 to supply water to the flushing pipeline 100. The measured pulse solenoid valve 200 then discharges the water from the flushing pipeline 100. The flow meter 300 detects the flushing water volume and outputs it to the control module 400. The control module 400 receives the flushing water volume and, when the flushing water volume is less than a first set value, deems the measured pulse solenoid valve 200 to be malfunctioning. The first set value can be set based on the parameters of the flushing pipeline 100 or the parameters of the measured pulse solenoid valve 200, and this embodiment does not impose any specific limitations thereon.

[0055] In another embodiment, the control module 400 outputs a control signal to control the pulse solenoid valve 200 being tested to close, so that the pulse solenoid valve 200 does not discharge water from the flushing pipeline 100. The flow meter 300 detects the flushing volume and outputs it to the control module 400. The control module 400 receives the flushing volume and, when the flushing volume is greater than a second set value, determines that the pulse solenoid valve 200 being tested is not closed properly. The second set value can be set based on the parameters of the flushing pipeline 100 or the parameters of the pulse solenoid valve 200 being tested, and this embodiment does not impose any specific limitations thereon.

[0056] Water is supplied to the flushing pipe 100 through the water supply module 500, and a complete water channel test environment is set up for the tested pulse solenoid valve 200 to the greatest extent, so as to simulate the water outlet water channel of the induction faucet, so as to improve the simulation degree of the aging test device; the opening and closing of the tested pulse solenoid valve 200 is controlled by the control module 400, and the flushing volume is detected by the flow meter 300 to detect the switch valve state of the tested pulse solenoid valve 200, thereby completing the aging test of the tested pulse solenoid valve 200. The aging test is completed in a highly simulated test environment, thereby improving the accuracy of the aging test, improving the stability of the water outlet flow of the applied induction faucet, and bringing a good user experience to the user.

[0057] like Figures 1 to 3 As shown, the water supply module 500 provided in some embodiments of the present invention includes: a water supply tank 510 , a constant pressure water tank 520 , a water pressure detector 530 and a pressure supply variable frequency pump 540 .

[0058] The water supply tank 510 is connected to one end of the pressure supply variable frequency pump 540, and the other end of the pressure supply variable frequency pump 540 is connected to the water inlet end of the constant pressure water tank 520. The constant pressure water tank 520 is provided with at least one water supply port, and the other end of the flushing pipe 100 is connected to one of the water supply ports.

[0059] In one embodiment, the water flow direction of the water supply module 500 is: the water in the water supply tank 510 flows into the constant pressure water tank 520 through the pressure supply variable frequency pump 540, and the water in the constant pressure water tank 520 flows into the flushing pipeline 100 through the water supply port.

[0060] The flushing pipe 100 can be connected to other water supply ports to complete the aging test. Each water supply port can be connected to a flushing pipe 100 to simultaneously perform aging tests on multiple pulse solenoid valves 200. The flushing pipe 100 can also be connected to each water supply port in a specific order. That is, after completing a aging test, the flushing pipe 100 is connected to a different water supply port and then the aging test is completed again. In this embodiment, the corresponding connection relationship between the flushing pipe 100 and the water supply ports is not further described.

[0061] A water pressure detector 530 is mounted on the constant-pressure water tank 520 and is electrically connected to the input of the controller 410 in the control module 400. The pressure-supply variable frequency pump 540 is electrically connected to the output of the controller 410 in the control module 400. The water pressure detector 530 detects the water pressure within the constant-pressure water tank 520 and outputs the pressure value to the controller 410. The pressure-supply variable frequency pump 540 receives a regulation signal from the controller 410 and pumps water from the water supply tank 510 to the constant-pressure water tank 520, thereby regulating the water pressure within the constant-pressure water tank 520 and maintaining a stable water pressure in the flushing pipe 100.

[0062] In one embodiment, the control module 400 outputs a control signal to control the measured pulse solenoid valve 200 to open. The water pressure detector 530 detects the output water supply pressure. In the controller 410 of the control module 400, when the water supply pressure is less than a set pressure, a regulation signal is output. The pressure supply variable frequency pump 540 receives the regulation signal and adjusts its speed to replenish water from the water supply tank 510 to the constant pressure water tank 520, bringing the water supply pressure to the set pressure. The constant pressure water tank 520 supplies water to the flushing pipeline 100. The measured pulse solenoid valve 200 discharges water from the flushing pipeline 100. The flowmeter 300 detects the flushing volume and outputs it to the control module 400. The control module 400 receives the flushing volume. If the flushing volume is less than a set first set volume, the measured pulse solenoid valve 200 is deemed to be malfunctioning. The first set volume and the set pressure can be set as needed and are not specifically limited in this embodiment.

[0063] Water is supplied to the flushing pipe 100 through the water supply tank 510, the constant pressure water tank 520 and the pressure supply variable frequency pump 540, and a complete water path is set up for the pulse solenoid valve 200 to the greatest extent possible, simulating the water path environment of the actual application of the induction faucet to improve the simulation degree of the aging test device. The water supply pressure in the constant pressure water tank 520 is adjusted through the pressure supply variable frequency pump 540 and the water pressure detector 530 to maintain the stability of the water pressure supplied to the flushing pipe 100, reduce the collection error of the flow meter 300, and improve the accuracy of the aging test. When aging testing is performed on multiple pulse solenoid valves 200 under test, stable water pressure can be provided to multiple flushing pipes 100, thereby improving the test efficiency and accuracy of the aging test, improving the stability of the water flow rate of the applied induction faucet, and bringing a good user experience.

[0064] like Figures 1 to 3 As shown, the pressure supply frequency conversion pump 540 provided in some embodiments of the present invention includes: a pressure supply water pump 541 and a pressure supply frequency converter 542.

[0065] The water supply tank 510 is connected to one end of the pressure water pump 541, the other end of the pressure water pump 541 is connected to the water inlet end of the constant pressure water tank 520, the input end of the pressure supply frequency converter 542 is electrically connected to the output end of the control module 400, the input end of the pressure supply frequency converter 542 is also electrically connected to the external driving power supply, and the output end of the pressure supply frequency converter 542 is electrically connected to the pressure water pump 541.

[0066] In one embodiment, the control module 400 outputs a control signal to control the measured pulse solenoid valve 200 to open. The water pressure detector 530 detects the output water supply pressure. In the controller 410 of the control module 400, when the water supply pressure is less than a set pressure, a regulation signal is output. The pressure supply inverter 542 receives the regulation signal and adjusts the speed of the pressure supply pump 541. The pressure supply pump 541 replenishes water from the water supply reservoir 510 to the constant pressure water tank 520, bringing the water supply pressure to the set pressure. The constant pressure water tank 520 supplies water to the flushing pipeline 100. The measured pulse solenoid valve 200 discharges water from the flushing pipeline 100. The flowmeter 300 detects the flushing volume and outputs it to the control module 400. The control module 400 receives the flushing volume. If the flushing volume is less than a first set volume, the measured pulse solenoid valve 200 is deemed to be malfunctioning. The first set volume and the set pressure can be set as needed and are not specifically limited in this embodiment.

[0067] like Figures 1 to 3 As shown, the control module 400 provided in some embodiments of the present invention includes: a controller 410 and a regulation circuit 420 .

[0068] The input end of the controller 410 is electrically connected to the flow meter 300 , and the controller 410 receives the flushing water volume output by the flow meter 300 ; the input end of the controller 410 is also electrically connected to the water pressure detector 530 , and the controller 410 receives the water supply pressure output by the water pressure detector 530 .

[0069] The output end of the controller 410 is electrically connected to the voltage supply inverter 542, and the controller 410 outputs a regulation signal to the voltage supply inverter 542. The output end of the controller 410 is also electrically connected to the input end of the control circuit 420, and the controller 410 outputs a control signal to the control circuit 420.

[0070] The controller 410 is a PLC controller. The controller 410 may also be other types of controllers, which are not specifically limited in this embodiment.

[0071] The input end of the control circuit 420 is electrically connected to the external driving power supply, and the output end of the control circuit 420 is electrically connected to the pulse solenoid valve 200 being measured. The control circuit 420 receives the control signal and controls the on-off between the external driving power supply and the pulse solenoid valve 200 being measured.

[0072] In one embodiment, the controller 410 outputs a control signal, causing the control circuit 420 to connect the driving power supply to the pulse solenoid valve 200 under test, causing the pulse solenoid valve 200 to open. The water pressure detector 530 detects and outputs the water supply pressure to the controller 410. When the water supply pressure is less than a set pressure, the controller 410 outputs a control signal. The pressure inverter 542 receives the control signal and adjusts the speed of the pressure pump 541. The pressure pump 541 replenishes water from the water supply reservoir 510 into the constant pressure water tank 520, bringing the water supply pressure to the set pressure. The constant pressure water tank 520 supplies water to the flushing pipeline 100, and the pulse solenoid valve 200 under test discharges the water from the flushing pipeline 100. The flow meter 300 detects the flushing water volume and outputs it to the controller 410. The controller 410 receives the flushing water volume and, if the flushing water volume is less than a set first set volume, determines that the pulse solenoid valve 200 under test is not opening properly. The first set amount and the set pressure can be set as needed, and this embodiment does not impose any specific restrictions on them.

[0073] In another embodiment, the controller 410 outputs a control signal, causing the control circuit 420 to cut off the path between the driving power supply and the pulse solenoid valve 200 being tested. The pulse solenoid valve 200 being tested closes and does not discharge water from the flushing pipeline 100. The flow meter 300 detects a flushing volume and outputs it to the controller 410. The controller 410 receives the flushing volume and, when the flushing volume is greater than a second set volume, determines that the pulse solenoid valve 200 being tested is not closed properly. The second set volume can be set based on the parameters of the flushing pipeline 100 or the parameters of the pulse solenoid valve 200 being tested, and this embodiment does not impose any specific limitations thereon.

[0074] The control circuit 420 includes a first relay 421 , a second relay 422 , a third relay 423 and an optocoupler isolator 424 .

[0075] The input end of the second relay 422 is electrically connected to the external driving power supply, the input end of the second relay 422 is electrically connected to the output end of the controller 410, and the output end of the second relay 422 is electrically connected to the input end of the optocoupler isolator 424; wherein, the output end of the second relay 422 can be electrically connected to the collector of the photosensitive element in the optocoupler isolator 424.

[0076] An input end of the first relay 421 is electrically connected to an output end of the controller 410 , and an output end of the first relay 421 is connected to an input end of the optocoupler isolator 424 .

[0077] The output end of the third relay 423 is electrically connected to the pulse solenoid valve 200 being measured, and the input end of the third relay 423 is electrically connected to the output end of the optocoupler isolator 424; wherein, the input end of the third relay 423 can be electrically connected to the emitter of the photosensitive element in the optocoupler isolator 424.

[0078] In one embodiment, the controller 410 outputs a control signal, which is received by the first and second relays 421 and 422. When the first and second relays 421 and 422 are turned on, the photosensor of the optocoupler isolator 424 is turned on, and external drive power is input to the third relay 423 via the second relay 422 and the optocoupler isolator 424. The third relay 423 is turned on, and external drive power is supplied to the pulse solenoid valve 200 under test via the third relay 423, causing the pulse solenoid valve 200 under test to open. In this embodiment, the control signal is a low-level pulse signal. The water pressure detector 530 detects and outputs the water supply pressure to the controller 410. When the water supply pressure is less than a set pressure, the controller 410 outputs a control signal. The pressure converter 542 receives the control signal and adjusts the speed of the pressure water pump 541. The pressure water pump 541 replenishes water from the water supply tank 510 into the constant pressure water tank 520, bringing the water supply pressure to the set pressure. The constant pressure water tank 520 supplies water to the flushing pipe 100. The pulse solenoid valve 200 under test discharges the water in the flushing pipe 100. The flow meter 300 detects the flushing water volume and outputs it to the controller 410. The controller 410 receives the flushing water volume and, if the flushing water volume is less than a first set value, determines that the pulse solenoid valve 200 under test is not opening properly. The first set value and the set pressure can be set as desired and are not specifically limited in this embodiment.

[0079] In another embodiment, the controller 410 outputs a control signal, which is received by the first and second relays 421 and 422. When the first and second relays 421 and 422 are turned off, the photosensor of the optocoupler isolator 424 is turned off, preventing the external drive power from being input to the third relay 423 via the second relay 422 and the optocoupler isolator 424. The third relay 423 is turned off, and the pulse solenoid valve 200 being tested is closed. In this embodiment, the control signal is a high-level pulse signal. The pulse solenoid valve 200 being tested does not discharge water from the flushing pipeline 100. The flowmeter 300 detects the flushing volume and outputs it to the controller 410. The controller 410 receives the flushing volume. If the flushing volume exceeds a second set value, the pulse solenoid valve 200 being tested is considered to be defective and has not closed. The second set value can be set based on the parameters of the flushing pipeline 100 or the parameters of the pulse solenoid valve 200 being tested, and this embodiment does not impose any specific limitations thereon.

[0080] like Figures 1 to 3 As shown, the aging test device provided by some embodiments of the present invention further includes: a first angle seat valve 600 , a first solenoid valve 610 , a vent pipe 700 , a second angle seat valve 710 , a second solenoid valve 720 and a leak detection sensor 800 .

[0081] The first angle seat valve 600 is installed at the other end of the flushing pipe 100, near the water supply port of the constant pressure water tank 520. The first solenoid valve 610 is connected to the first angle seat valve 600. The first solenoid valve 610 is electrically connected to the output end of the controller 410. The first solenoid valve 610 controls the first angle seat valve 600.

[0082] Exemplarily, the controller 410 outputs an opening signal to the first solenoid valve 610 , and the first solenoid valve 610 is energized to control the first angle seat valve 600 connected thereto to open, so that the constant pressure water tank 520 supplies water to the flushing pipe 100 .

[0083] The first solenoid valve 610 and the first angle seat valve 600 cooperate to control the input of water into the constant pressure water tank 520 .

[0084] The vent pipe 700 is located on one side of the flow meter 300 and is connected to the flushing pipe 100. A second angle seat valve 710 is provided on the vent pipe 700. A second solenoid valve 720 is electrically connected to the output terminal of the controller 410 and is connected to the second angle seat valve 710. The second solenoid valve 720 controls the second angle seat valve 710 to control the opening and closing of the vent pipe 700.

[0085] Exemplarily, the controller 410 outputs an opening signal to the second solenoid valve 720 , and the second solenoid valve 720 is energized to control the second angle seat valve 710 connected thereto to open, thereby ventilating the vent pipe 700 .

[0086] The leak detection sensor 800 is located on the other side of the flow meter 300 and is electrically connected to the input end of the controller 410 . The leak detection sensor 800 detects the flushing water pressure of the flushing pipe 100 and outputs the flushing water pressure to the controller 410 .

[0087] In one embodiment, before performing a burn-in test, the controller 410 outputs an open signal to the second solenoid valve 720, which opens the second angle seat valve 710 and vents the vent pipe 700. The controller 410 then outputs a close signal to the second solenoid valve 720, which closes the second angle seat valve 710 and closes the vent pipe 700. The leak detection sensor 800 outputs the flushing water pressure to the controller 410. The controller 410 determines whether the flushing pipe 100 and the solenoid valve are leaking based on the pressure changes of the flushing water pressure, thereby performing a safety test before the burn-in test and improving the stability and safety of the burn-in test apparatus. The remaining solenoid valves are all closed.
