[0035] The water inlet amount of the water tank 2 can be controlled according to demand. The water inlet amount can be preset on the display screen 49. After pressing the water inlet button 47 of the water tank 2, the water tank water inlet solenoid valve 6 is opened, and the water level detector monitors the water level of the water tank 2 in real time. When the preset water level is reached, the water tank water inlet solenoid valve 6 is closed;

[0036] When the water tank drain valve 9 is opened, a signal is transmitted to the control system 23. At this time, even if the water tank 2 water inlet button 47 is pressed, the water tank water inlet solenoid valve 6 will not open;

[0040] When the system is not in use, the water tank drain valve 20 can be opened to drain the water in the water tank 13; the water tank drain valve 9 can be opened to drain the water in the water tank 2;

[0041] The display screen 49 can be used to set the water inflow of the water tank 2, the water supply amount, the water supply time, the cumulative leakage of the toilet to be tested, and can also display the remaining water amount of the water tank 2, fault information, monitoring screen playback and other information;

[0043] The water pump 4 is fixed on the water pump bracket 5. There is a shock-absorbing pad under the water pump bracket 5 to prevent the water pump 4 from being directly fixed on the cabinet 51 and causing vibration and noise.

[0044] The purpose of providing the pulley 50 is to facilitate the movement of the cabinet 51 and improve the convenience of detection;

The main cabinet door 1 and the rear cabinet door 11 are usually closed to prevent non-professionals from modifying the detection parameters and damaging components, which will affect the system function.

[0046] The working principle and use process of the utility model are as follows: when the water tank 2 is short of water and the water tank drain valve 9 is closed, a predetermined water inflow volume is set on the display screen 49, the water tank 2 water inflow button 47 is pressed, the water tank water inflow solenoid valve 6 is opened, and the water level monitor 3 monitors the water inflow volume in real time. When the set water level is reached, the water tank water inflow solenoid valve 6 is closed;

[0047] The following describes the testing process using a toilet as an example: Connect the water source, air source, and power source, place the toilet to be tested on the cabinet 51, and install the squat toilet on the squat toilet bracket 40. Connect the toilet's water inlet, slide valve opening air inlet, and slide valve closing air inlet to the toilet's water inlet 42, toilet opening connection port 43, and toilet closing connection port 44, respectively. Connect the water outlet to the toilet's water outlet 31. Press the toilet test button 45, and the S1 valve body of the toilet solenoid valve 14 will be energized. Gas will pass through the toilet solenoid valve 14 to close the toilet's slide valve. Simultaneously, the water tank water supply contactor 28 will operate, controlling the water pump 4 to start working and opening the water tank water supply solenoid valve 26. Simultaneously, the water tank water inlet solenoid valve 18 will open, and the water pump 4 will pump water from the water tank 2 into the water tank 13.

[0048] When the water tank level 21 is reached, the water tank water contactor 28 stops working, the water pump 4 stops working, the water tank water solenoid valve 26 and the water tank water inlet solenoid valve 18 are closed, and the water tank pressurization solenoid valve 15 is opened. The gas controls the water outlet pneumatic valve 19 to open after passing through the water tank pressurization solenoid valve 15. At the same time, the gas enters the water tank 13 to pressurize the water tank 13 and provide the water in the water tank 13 to the toilet to be tested. At this time, the toilet to be tested takes 30 seconds. During the whole process, the water immersion sensor 8 monitors and detects whether there is water in the small water tank 7 in real time.

[0049] If the toilet is leaking, the water sensor 8 immediately outputs a signal, the alarm 10 lights up red, and the micro-liquid flow meter 24 begins to detect the cumulative amount of leaked water and displays the result on the display 49. The leaked water flows back into the water tank 2 through the small water tank return port 204.

[0050] If the toilet under test is not leaking, the water sensor 8 will not output a signal, and the alarm 10 will light up green. After 30 seconds, the valve body S2 of the toilet solenoid valve 14 will be energized, and the gas will open the slide valve of the toilet under test through the toilet solenoid valve 14. The water in the toilet under test will flow back to the water tank 2 through the water sensor 8, the micro liquid flow meter 24, and the small water tank return port 204.

[0051] To provide a fixed amount of water, the user enters the desired water volume on display screen 49 and presses water supply button 46. This activates water supply contactor 29, controlling water pump 4 and opening water supply solenoid valve 27. Flow sensor 25 monitors the amount of water flowing through in real time, and water in water tank 2 is then delivered to external devices through water supply port 37 of cabinet 51. When the desired water volume is reached, water supply contactor 29 ceases operation, controlling water pump 4 and closing water supply solenoid valve 27, and water supply ends.

[0052] To schedule water supply, enter the scheduled water supply time on display 49 and press water supply button 46. This activates water supply contactor 29, controlling water pump 4 and water supply solenoid valve 27 to open. Water in water tank 2 is then delivered to external devices via water pump 4, water supply solenoid valve 27, flow sensor 25, and water supply port 37. When the scheduled time is reached, water supply contactor 29 ceases operation, controlling water pump 4 and water supply solenoid valve 27 to close, and water supply ends.

[0053] The system also has a component self-test function: when the system self-test button 48 is pressed, the water tank water supply contactor 28 is activated, the water pump 4 starts working, the water tank water supply solenoid valve 26 and the water tank water inlet solenoid valve 18 are opened, and when the water in the water tank 13 reaches the water tank liquid level 21, the water pump 4 stops working, and the water tank water supply solenoid valve 26 and the water tank water inlet solenoid valve 18 are closed;

[0054] If the water tank liquid level 21 detects no signal after a period of time, the water outlet pneumatic valve 19 is damaged, the alarm 10 lights up a yellow light, and the display screen 49 displays "water outlet pneumatic valve 19 is damaged."

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
