The guide plate 45 is positioned at the lower side of the wiping bar 21 and is inclined towards the lower rear side to receive the dirty liquid scraped off from the cleaning roller 3 by the wiping bar 21 and guide the dirty liquid to flow into the dirty liquid inlet 431.

The operation of the floor wiping machine 100 will now be described. When the floor cleaning machine 100 performs a cleaning operation, the floor cleaning machine 100 starts the driving motor 6 and the cleaning motor 34, and the driving motor 6 drives the cleaning roller 3 to rotate on the floor to be cleaned. The cleaning liquid in the solution tank 31 is supplied to the fluid distributor 33 through the fluid supply path 32 by the cleaning motor 34, and then the fluid distributor 33 distributes the cleaning liquid therein to the rotating cleaning roller 3, and the cleaning roller 3 rotates with the cleaning liquid and performs the cleaning work on the floor to be cleaned.

The wiping strip 21 abutting against the surface of the cleaning roller 3 wipes off the excess dirty liquid adhering to the surface of the cleaning roller 3, and the wiped dirty liquid flows backward along the wiping strip 21 under the action of its surface tension and gravity and drops onto the liquid receiving portion 451. The dirty liquid on the liquid receiving portion 451 flows to the pair of dirty liquid inlets 431 along the inclined surface of the guide plate 45 by gravity, and finally flows in through the dirty liquid inlets 431 and is stored in the corresponding first chamber 411.

The liquid level in the first chamber 411 continuously rises as the dirty liquid continuously flows in. When the liquid level in the first chamber 411 is higher than the liquid level corresponding to the overflow port 414, the dirty liquid flows into the second chamber 412 through the overflow port 414, the garbage such as large particles and impurities carried by the dirty liquid is deposited at the inner bottom of the first chamber 411 and is blocked by the partition 413 to be collected in the pair of first chambers 411, and the dirty liquid rising to the upper part of the overflow port 414 in the first chamber 411 flows into the second chamber 412 from the overflow port 414. The floater 5 located in the second chamber 412 floats up and down along with the liquid level of the second chamber 412, and when the liquid level of the second chamber 412 rises to a set liquid level, the warning lamp 13 connected with the floater 5 sends out a warning outwards to provide a user for dumping the cleaning liquid in the dirty liquid storage box 4.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the foregoing description only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims, specification, and equivalents thereof.
