The spray suction head uses the prior art, which is not described herein.

[0176] The clean water tank 2 is provided with a clean water tank high liquid level sensor, a clean water tank low liquid level sensor, and a clean water tank empty liquid level sensor for detecting whether there is decontamination liquid in the clean water tank 2. The clean water tank 2 is provided with a first liquid inlet 2a for realizing the entry of the decontamination liquid and being in communication with the first liquid inlet pipe 8, and a first liquid outlet 2b for realizing the flow of the decontamination liquid and being in communication with the first liquid outlet pipe 9.

[0177] Due to the cooperation of the clean water tank high liquid level sensor, the clean water tank low liquid level sensor, and the water pump on the first liquid inlet pipe, the working of the clean water tank in use is as follows: when the liquid surface in the clean water tank reaches the low predetermined value, the corresponding water pump works to make the decontamination liquid enter the clean water tank, and when the liquid surface in the clean water tank reaches the high predetermined value, the corresponding water pump stops working to stop the liquid entering the clean water tank, so as to realize the automatic entry and exit of the decontamination liquid in the clean water tank, and keep the liquid surface height in the clean water tank between the low predetermined value and the high predetermined value, thereby ensuring that the clean water tank can always supply the normal use of the spray suction head. In the first use, the decontamination can be carried out only when the liquid surface in the clean water tank reaches the low predetermined value.

[0178] In the present application, since the sewage tank is in a negative pressure state during decontamination, in order to ensure the normal discharge of the decontamination liquid in the sewage tank, part of the decontamination liquid is retained in the second liquid discharge pipe after the liquid is discharged in the second liquid discharge pipe, at this time the decontamination liquid in the second liquid discharge pipe is in communication with the decontamination liquid in the sewage tank, so that the liquid discharge of the second liquid discharge pipe is not affected by the negative pressure in the sewage tank. Specifically, the working of the sewage tank is as follows: under the condition that there is no decontamination liquid in the second liquid discharge pipe, i.e. when the decontamination equipment is used for the first time, when the liquid level in the sewage tank reaches the detection position of the high liquid level sensor of the sewage tank, the suction head 7 is paused, which means that the vacuum pump and the cleaning pump 12b on the first liquid discharge pipe are paused, so that the air pressure in the sewage tank is restored to atmospheric pressure from below atmospheric pressure, then the sewage pump 12c located on the second liquid discharge pipe works, so that there is decontamination liquid in the entire second liquid discharge pipe, then the vacuum pump and the cleaning pump 12b on the first liquid discharge pipe continue to work, and when the liquid in the sewage tank cannot be detected by the low liquid level sensor of the sewage tank, the sewage pump 12c on the second liquid discharge pipe stops working.

[0179] Under the condition that there is decontamination liquid in the second liquid discharge pipe, when the liquid in the sewage tank can be detected by the low liquid level sensor of the sewage tank, the sewage pump 12c on the second liquid discharge pipe starts to work again, so that the decontamination liquid in the sewage tank is discharged through the second liquid discharge pipe, and when the liquid in the sewage tank cannot be detected by the low liquid level sensor of the sewage tank, the water pump on the second liquid discharge pipe stops working. When the liquid level in the sewage tank reaches the detection position of the high liquid level sensor of the sewage tank, the decontamination equipment is automatically stopped for protection of the vacuum pump.

[0180] In the present embodiment, the vacuum pump 6, the suction head 7 and the sewage tank 4 are each provided with two, each suction head 7 is placed in the accessory tank 5 provided on the rack 3, the two accessory tanks 5 are respectively arranged on the left and right sides of the rack 3, the two sewage tanks 4 are arranged side by side on the upper front side of the rack 3, the clean water tank 2 is arranged in the rack 3 and located at the rear side of the sewage tank 4, and the clean water tank 2 and the two sewage tanks 4 are arranged between the two accessory tanks 5, and the panel 1 is arranged on the top surface of the rack 3.

[0184] When any of the first buttons is pressed, the corresponding spray suction head enters the decontamination, and the clean water tank and the corresponding sewage tank work according to the above process. At the same time, the cleaning pump on the corresponding first liquid outlet and the vacuum pump on the corresponding sewage tank work. When any of the first buttons is pressed, the corresponding spray suction head enters the pause decontamination, the corresponding sewage tank pauses discharging liquid, and the cleaning pump on the corresponding first liquid outlet and the vacuum pump on the corresponding sewage tank stop working, so that the corresponding spray suction head stops decontamination. Only when the two second buttons are pressed at the same time, the two spray suction heads enter the pause decontamination, and the clean water tank pauses liquid inlet.

[0185] When the second button is pressed, the water pump on the first liquid inlet and the water pumps on the two first liquid outlets work, so that the decontamination liquid in the clean water tank is discharged. At this time, in order to prevent pollution, the spray suction head is directly inserted into the folding sewage bag. When the clean water tank emptying liquid level sensor detects that the clean water tank is empty, the water pump on the first liquid inlet and the water pumps on the two first liquid outlets stop working. Alternatively, the clean water tank emptying liquid level sensor is not arranged, and the water pump on the first liquid inlet and the water pumps on the two first liquid outlets work for a period of time and then stop. When the third button is pressed, the vacuum pump of the sewage tank stops working, and the water pumps on the two second liquid outlets work. When the second emptying liquid level sensor detects that the decontamination liquid in the corresponding sewage tank is empty, the water pumps on the two second liquid outlets stop working. Alternatively, the second emptying liquid level sensor is not arranged, and the water pumps on the two second liquid outlets work for a period of time and then stop.
