However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Furthermore, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the specific shapes, configurations, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

Hereinafter, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

Furthermore, spatially relative terms such as "under … …," "under … …," "under … …," "lower," "above … …," "upper," "above … …," "higher," "side" (e.g., as in "sidewall") and the like are used herein to describe one element's relationship to another element(s) as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below … …" may include both upper and lower orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In this application, unless specifically stated and limited otherwise, the term "abutting" means that two objects are brought together with a small gap, in which the liquid cannot flow smoothly under its own surface tension. For example: the term "adjacent to" in the sense that the liquid-bearing portion of the deflector is adjacent to the cleaning roller and located below the scraper "means that the liquid-bearing portion of the deflector is close to the cleaning roller and leaves a small gap, and the liquid cannot smoothly flow in the small gap under the action of the surface tension of the liquid.

In the present application, unless explicitly specified and limited otherwise, the term "coupled" is to be construed broadly, and for example, "coupled" may be either fixedly coupled, detachably coupled, or integrally formed; can be directly connected or indirectly connected through an intermediate medium.

The diversion portion 452 is integrally connected to the lid 43 and is configured to be simultaneously connected to a pair of dirty liquid inlets 431. The deflector 45 is located at the lower side of the wiper strip 21 and is inclined toward the rear lower side to receive the dirty liquid scraped off from the cleaning roller 3 by the wiper strip 21 and guide the dirty liquid thereof to the dirty liquid inlet 431.

The operation of the floor scrubbing machine 100 will now be described. When the floor cleaning machine 100 is in cleaning work, 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 reaches the fluid distributor 33 through the liquid delivery path 32 by the cleaning motor 34, and then the fluid distributor 33 distributes the cleaning liquid inside to the rotating cleaning roller 3, and the cleaning roller 3 carries the cleaning liquid to rotate and performs cleaning work on the floor to be cleaned.

The wiping strip 21 abutting against the surface of the cleaning roller 3 wipes off the excessive dirty liquid adhering to the surface of the cleaning roller 3, and the scraped dirty liquid flows backward along the wiping strip 21 under the action of self surface tension and gravity and drops onto the liquid bearing portion 451. The dirty liquid on the liquid carrying portion 451 flows along the inclined surface of the baffle 45 to the pair of dirty liquid inlets 431 under the action of 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 increases as the contaminated 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 waste liquid flows into the second chamber 412 through the overflow port 414, and the waste such as large particles and sundries carried by the waste liquid is deposited at the inner bottom of the first chamber 411 and is blocked by the partition 413 to be concentrated in the first chambers 411, and the waste liquid rising to the upper part of the overflow port 414 in the first chamber 411 flows from the overflow port 414 into the second chamber 412. The float 5 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 the set liquid level, the warning lamp 13 in signal connection with the float 5 gives warning to the outside to provide the user to pour the cleaning liquid in the dirty liquid storage box 4.

The foregoing has shown and described the basic principles, principal 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 foregoing embodiments, which have been described in the foregoing embodiments and description merely illustrates the principles of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, the scope of which is defined in the appended claims, specification and their equivalents.
