The pressure box 70 also has two through holes 75, 76 communicating with the cleaning chamber 78. One of the through holes 75 is connected to the connection port 23 of the clean water container 20 through a hose. Another through hole 76 is connected to the connection port 34 of the sewage container 30 through a hose. The clean water of the clean water container 20 enters from the through hole 75 by the water pump 49 and flows along the cleaning chamber formed in the pressure box 70. When the clean water flows in the cleaning chamber, it cleans the surface of the wiping layer flowing through cleaning chamber, and the fluid is discharged from the through hole 76 of the pressure box 70 connected to the sewage container 30.

[0046] The pressing device 73 near the garbage collection device 60 is made of a metal material, thereby increasing the strength of the pressing device 73. The pressing device 73 can quickly peel off the garbage adhered to the wiping layer 56 and cause the garbage to fall into the garbage collection device 60. The garbage can be prevented from sticking to the wiping layer 56. In this way, garbage can be prevented from adhering to the wiping layer 156, and the wiping layer 156 can be cleaned by the decontamination device to improve the wiping effect of the wiping layer 156.

[0047] A cleaning chamber for holding a cleaning fluid is formed between the divider 74 and the pressing devices 73, 77. The cleaning chamber resembles a channel. The cleaning fluid enters the cleaning chamber from the through hole 75, and then passes through the through hole 76. The fluid enters the sewage container 30 through the connection port 34.

[0048] The disclosure respectively provides a separate clean water container 20 with a water inlet 22 and a sewage container 30 provided with a sewage outlet 32, which can make the cleaning fluid in the decontamination device circulate more smoothly.
