[0077] Specifically, the length of the first cleaning member is greater than the length of the second cleaning member.

[0078] Specifically, there are at least two cleaning members 20, and the at least two cleaning members 20 are spaced apart on the mounting base 10. The cleaning structure further includes a dirt scraping member 30, and the dirt scraping member 30 is arranged between the at least two cleaning members 20.

Specifically, during the sewage scraping process of the sewage scraping member 30, not only sewage but also large particulate impurities may enter the sewage collecting groove 41 of the sewage collecting member 40.

[0080] In this embodiment, the cleaning structure further includes a filtering member 60 and a sewage suction pipe 70. The filtering member 60 is installed in the sewage collecting groove 41. The filtering member 60 is adapted to the inner peripheral wall of the sewage collecting groove 41, and the filtering member 60 is clamped or attached to the inner peripheral wall of the sewage collecting groove 41 to divide the filtering member 60 into a sewage chamber and a filtering chamber. The sewage suction pipe 70 penetrates through the filtering member 60. The sewage suction pipe 70 passes through the sewage chamber and enters the filtering chamber, and the sewage suction pipe 70 communicates with the filtering chamber. With such a structural arrangement, it is convenient to better filter the sewage in the sewage collecting groove 41 of the sewage collecting member 40, avoid the situation that large particulate impurities are sucked into the sewage tank through the sewage suction pipe 70, causing blockage of the sewage suction pipe 70 and / or the sewage tank, and ensure that the sewage suction pipe 70 can smoothly perform the sewage suction operation.

[0081] Specifically, along the extending direction from the bottom of the sewage collecting groove 41 to the opening of the sewage collecting groove 41, the filtering chamber and the sewage chamber are arranged at intervals. During the normal cleaning process of the cleaning structure, the filtering chamber is located below the sewage chamber.

[0082] Specifically, a relief opening 611 is provided on the filtering member 60, and the sewage suction pipe 70 penetrates through the relief opening 611. A sealing member is sleeved on the sewage suction pipe 70. The sealing member is located below the sewage scraping member 30 and is in interference fit with the filtering member 60 in the vertical direction.

[0083] Specifically, the distance between the sewage suction port 71 of the sewage suction pipe 70 and the bottom of the sewage collecting groove 41 is greater than the pore diameter of the filtering holes of the filtering member 60 and less than or equal to 1 mm. In this way, it is convenient to better avoid the situation that some impurities accidentally entering the filtering chamber are sucked away by the sewage suction port 71, and better avoid the blockage of the sewage suction pipe 70.

[0084] Specifically, at least a part of the bottom of the sewage collecting groove 41 is inclined, and the sewage suction port 71 of the sewage suction pipe 70 is disposed opposite to the lowest part of the bottom of the sewage collecting groove 41. In this way, it is convenient for the sewage suction port 71 to better suck away the filtered sewage, and avoid the situation that too much sewage accumulates in the sewage collecting member 40 and cannot be quickly discharged.

[0085] Specifically, the bottom surface of the sewage collecting tank 41 can be a structure of inclined plane-inclined plane, that is, inclined planes on both sides and a plane in the middle, and the middle plane corresponds to the lowest point. Specifically, the area near the sewage extraction port 71 of the sewage extraction pipe 70 is a plane, and it is the lowest position of the bottom of the sewage collecting tank 41. There is a gap of 0 to 1 mm between the sewage extraction port 71 of the sewage extraction pipe 70 and the bottom plane of the sewage collecting tank 41, and this gap value needs to be larger than the aperture of the filter. The filter element 60 is provided with a handle to facilitate the user to take it out, and the number of handles is not limited.

[0086] In this embodiment, the scraping member 30 has two scraping surfaces arranged opposite to each other, and the angle between the scraping surfaces and the horizontal plane is greater than or equal to 30° and less than or equal to 60°. With such a structural arrangement, it is convenient to better scrape the sewage on the cleaning member 20. Specifically, the two scraping surfaces are arranged toward the two cleaning members 20 respectively.

[0087] When the cleaning structure of this embodiment is used, when the roller mop (corresponding to the cleaning member 20) rotates, the scraping member 30 interferes with the roller mop, scraping the sewage on the mop, and the sewage is filtered from top to bottom by the filter member 60 and reaches the bottom of the sewage collecting tank 41, and is guided by the inclined surface at the bottom to the vicinity of the sewage extraction port 71 of the sewage extraction pipe 70, and then is extracted to the sewage tank. Large solid particles and hair in the sewage are blocked by the filter screen and the sealing structure, and stay above the filter assembly.

[0088] Specifically, the scraper 30 is obtained by bending a sheet metal and has a certain inclined surface, and the angle between the inclined surface and the horizontal plane is about 30 to 60 degrees.

[0089] When the user needs to disassemble and clean the filter assembly, there is no need to turn over the sweeper. The user only needs to lift one side of the sweeper where the swing arm bracket is set, turn the knob by hand to contact the snap-in state of the swing arm bracket, pull out the dirt collecting part 40 from the side, and use the handle 100 to take the filter assembly out of the dirt collecting tank 41 to clean the filter assembly. By arranging the filter assembly horizontally in the dirt collecting tank 41, the filtering area is increased, and high-reliability sewage filtration and convenient user maintenance are achieved.

[0090] The utility model also provides a cleaning sweeper, comprising the cleaning structure provided above.

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0093] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0094] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0095] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0096] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present application.

[0097] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
