At the same time, the gray water tank solenoid valve 41 is closed. When the first-level filter box liquid level 63 is not activated, the gray water tank delayed emptying relay 44 controls the first-level filter slide valve 48 to open after a delay of 1 second. At the same time, the first-level filter slide valve position sensor 4801 controls the first-level filter box overflow solenoid valve 47 to open, so that the first-level filter box 72 maintains a normal pressure state. The wastewater in the gray water tank 70 is filtered by the first-level filter 39 and discharged into the first-level filter box 72. After 3 seconds, the gray water tank delayed emptying relay 44 controls the first-level filter slide valve 48 to close.

[0050] When the wastewater in the first-stage filter box 72 reaches the first-stage filter box liquid level 63, the first-stage filter box liquid level 63 outputs a signal to the first-stage filter slide valve 48, prohibiting the first-stage filter slide valve 48 from opening; at the same time, the first-stage filter box liquid level 63 outputs a signal to the filter box pressurization timer 50, at this time the filter box pressurization timer 50 starts timing, if the set time is reached and no signal from the first-stage filter box pressure sensor 62 is received, it means that the first-stage filter box pressure sensor 62 is damaged, at this time the filter box pressurization timer 50 controls the filter box air pump 38 to stop working, and the first-stage filter box pressure sensor fault indicator 19 lights up; at the same time, the first-stage filter box liquid level 63 outputs a signal to control the start of the filter box air pump 38, and inputs air pressure to the first-stage filter box 72 through the first-stage filter box solenoid valve 37. When it reaches the first After the first-stage filter box pressure sensor 62 is set to a value, the first-stage filter box pressure sensor 62 outputs a signal to the filter box air pump 38, the first-stage filter box solenoid valve 37 and the filter box delayed emptying relay 45, and the filter box air pump 38 stops outputting. At the same time, the first-stage filter box solenoid valve 37 is closed. When the second-stage filter box liquid level 73 is not activated, the filter box delayed emptying relay 45 controls the second-stage filter slide valve 53 to open after a delay of 1 second. At the same time, the second-stage filter slide valve position sensor 5301 outputs a signal to the timer 51. The timer 51 controls the ultraviolet lamp 65 and the ozone generator 55 to start. The wastewater in the first-stage filter box 72 is filtered by the second-stage filter 54 and then discharged into the second-stage filter box 64. After 3 seconds, the filter box delayed emptying relay 45 controls the second-stage filter slide valve 53 to close.

[0051] When the water in the secondary filter box 64 reaches the secondary filter box liquid level 73, the secondary filter box liquid level 73 immediately outputs a signal to the secondary filter slide valve 53, prohibiting the secondary filter slide valve 53 from opening. At the same time, the secondary filter box liquid level 73 outputs another signal to the detection water tank delay relay 46 after a delay. The detection water tank delay relay 46 controls the detection water pump 40 to start and the secondary filter box solenoid valve 60 to open. After 10 seconds, the detection water tank delay relay 46 controls the detection water pump 40 and the secondary filter box solenoid valve 60 to close.

At the same time, the secondary filter box water quality detection module 69 outputs a signal to the timer 51, and the timer 51 controls the ultraviolet lamp 65 and the ozone generator 55 to start and purify again;

[0053] The wash basin water purification circulation system also has a one-touch emptying function. After pressing the gray water tank one-touch emptying button 8, the gray water tank air pump 35 starts to pressurize the gray water tank 70. When the gray water tank pressure sensor 71 reaches the set value, the gray water tank delayed emptying relay 44 controls the first-level filter slide valve 48 to open after a delay of 1 second. At the same time, the first-level filter slide valve position sensor 4801 controls the first-level filter box overflow solenoid valve 47 to open, so that the first-level filter box 72 maintains a normal pressure state. The water in the gray water tank 70 is discharged into the first-level filter box 72.
