DETAILED DESCRIPTION

[0017] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0018] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present.

[0019] For ease of description, spatially relative terms, such as "upper", "lower", "left", "right", and the like, can be used herein for the purpose of illustrating one element or feature's relationship to another element or feature, as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if a device is inverted, elements described as being "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The terms "first", "second", "third", etc. can be used herein to describe various elements, regions, layers and / or sections, which have the same or similar characteristics or functions.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. The use herein of the terms "including", "comprising", "having" and the like are specifically intended to encompass the presence of one or more of the stated items or recited components rather than exclusion of any of the items or components.

[0021] The application will be described in detail below with reference to the attached drawings:

[0022] Device structure:

[0023] The cleaning machine body 1 is provided with a water supply pipe 16 and a drain pipe 2.

[0024] The filter box 3 is arranged on one side of the cleaning machine body 1 and is used for effectively filtering the wastewater discharged by the cleaning machine. The filter box 3 is provided with a water inlet on the top and is connected with the drain pipe 2 of the cleaning machine body 1.

[0025] The first filter cavity 4 is arranged on the top of the filter box 3, and the first filter cavity 4 is provided with a first filter screen 5 arranged obliquely therein. The first filter screen 5 is used for coarsely filtering the wastewater. The low end of the first filter screen 5 is provided with a drain valve 6, which is used for draining the excess wastewater.

[0026] The first liquid level sensor 7 is installed in the first filter cavity 4 and is used for monitoring the water level in the first filter cavity 4. When the liquid level reaches the first liquid level sensor 7, the proportion of impurities and particles in the wastewater is large at this time, and the control is made to open the drain valve 6 to drain the remaining wastewater in the first filter cavity 4.

[0027] The second filter cavity 8:

[0028] The first filter screen 5 is below which a second filter cavity 8 is arranged, and the second filter cavity 8 is slidably installed with a second filter screen 9, the second filter screen 9 is used for fine filtering of the wastewater, and the second filter screen 9 is below which an upper liquid level sensor 10 and a lower liquid level sensor 11 are arranged on the side wall, and the water level change in the second filter cavity 8 is monitored, and when the upper liquid level sensor 10 detects the water level information, the drain valve 6 is controlled to be opened, and the wastewater is directly drained away.

[0029] The water outlet pipe 15 is arranged on the side wall of the second filter cavity 8, and the distance between the water outlet pipe 15 and the second filter screen 9 is greater than the distance between the lower liquid level sensor 11 and the second filter screen 9.

[0030] The water supply system comprises:

[0031] The cleaning machine body 1 is arranged with a water supply pipe 16, and the water supply pipe 16 is connected with a first valve 18 and a second valve 19 through a three-way head 17. The first valve 18 is connected with a water source pipe 20, and the water source pipe 20 is used for connecting an external water supply source; the second valve 19 is connected with the water outlet pipe 15, and the water outlet pipe 15 is arranged with the water pump 14, so that the cleaning machine can be supplied with water continuously when needed.

[0032] When the cleaning machine uses the circulating water to supply water, the first valve 18 is closed, and the second valve 19 is opened, and the water in the second filter cavity 8 is pumped to the water supply pipe 16 through the water pump 14, and when the lower liquid level sensor 11 detects the liquid level information, it indicates that the water amount in the second filter cavity 8 is about to be insufficient, at this time, the second valve 19 is closed and the first valve 18 is opened, and the water supply source is used for supplementing water supply.

[0033] If the cleaning machine does not use circulating water, the first valve 18 is opened, and the second valve 19 is closed, and the water supply source is used for water supply.

[0034] The working process is as follows:

[0035] During the cleaning process, the sewage flows into the filter box 3 through the water inlet, is first filtered by the first filter screen 5, and the larger particles are intercepted, and the clean water with small particles flows into the second filter cavity 8.

[0036] The second filter screen 9 further filters the small particles in the water, and the filtered water falls into the second filter cavity 8 for subsequent use or treatment.

[0037] When the second filter screen 9 needs to be cleaned, the user only needs to pull the handle 13 on the connecting plate 12, and the second filter screen 9 can be easily taken out for cleaning or replacement, and the maintenance is convenient.

[0038] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
