[0073] Specifically, the length of the first cleaning member is greater than the length of the second cleaning member.

[0074] Specifically, there are at least two cleaning members 20, and the at least two cleaning members 20 are arranged at intervals 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.

[0075] Specifically, the dirt collecting member 40 is arranged between the at least two cleaning members 20, and the limiting member 50 is arranged at the ends of the at least two cleaning members 20. With such a structural arrangement, it is possible to better optimize the arrangement positions of the dirt collecting member 40 and the limiting member 50, avoid interference between the movement of the limiting member 50 and the movement of the cleaning members 20, and facilitate better collection of the sewage on the at least two cleaning members 20 through the dirt collecting member 40. Specifically, during the dirt scraping process of the dirt scraping member 30, not only sewage will enter the dirt collecting member 40, but also large particle impurities and the like may enter the dirt collecting groove 41 of the dirt collecting member 40.

[0076] 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 dirt collecting groove 41, and the filtering member 60 is adapted to the inner peripheral wall of the dirt collecting groove 41. The filtering member 60 is clamped or adhered to the inner peripheral wall of the dirt 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, and the sewage suction pipe 70 passes through the sewage chamber and enters the filtering chamber, and the sewage suction pipe 70 is communicated with the filtering chamber. With such a structural arrangement, it is possible to better filter the sewage in the dirt collecting groove 41 of the dirt collecting member 40, avoid the situation that large particle impurities are pumped into the sewage tank through the sewage suction pipe 70, resulting in 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.

[0077] Specifically, along the extending direction from the bottom of the dirt collecting groove 41 to the notch of the dirt 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.

[0078] Specifically, the cleaning structure further includes a sealing member 90, and the sealing member 90 is arranged between the filtering member 60 and the sewage suction pipe 70 to seal the gap between the filtering member 60 and the sewage suction pipe 70. In this way, it is possible to better separate the filtering chamber and the sewage chamber, and avoid the situation that large particle impurities in the sewage chamber enter the filtering chamber and are pumped away by the sewage suction pipe 70. The sealing member can be made of soft rubber material.

[0079] Specifically, the filter 60 is provided with a clearance opening 61, and the sewage extraction pipe 70 is arranged at the clearance opening 61. The sealing member is sleeved on the sewage extraction pipe 70, and the sealing member is located below the dirt scraping member 30 and is interference-fitted with the filter 60 in the vertical direction.

[0080] In this embodiment, the filter element 60 is interference fit with the inner peripheral wall of the dirt collecting tank 41, so as to effectively separate the filter cavity and the sewage cavity and avoid the mixing of the filter cavity and the sewage cavity. Specifically, ribs can be provided on the outer peripheral edge of the filter element 60 to achieve interference fit, and specifically, the interference amount is less than 0.5 mm. A gap can be provided between the portion without ribs and the dirt collecting tank 40, but the gap needs to be less than 0.5 mm to prevent large particles from passing through.

[0081] Specifically, the distance between the sewage extraction port 71 of the sewage extraction pipe 70 and the bottom of the sewage collection tank 41 is greater than the aperture of the filter hole of the filter element 60 and less than or equal to 1 mm. In this way, it is convenient to better avoid the situation where some impurities that mistakenly enter the filter cavity are sucked away by the sewage extraction port 71, and better avoid the situation where the sewage extraction pipe 70 is blocked.

[0082] In this embodiment, a handle 100 is provided on the filter element 60, and the handle 100 is located on one side of the notch of the filter element 60 close to the sump 41, and the handle 100 protrudes from the filter element 60.

[0083] Specifically, the filter element 60 includes a bracket and a filter screen, and the filter screen is installed on the bracket.

[0084] Specifically, at least part of the bottom of the sewage collecting tank 41 is inclined, and the sewage extraction port 71 of the sewage extraction pipe 70 is arranged opposite to the lowest part of the bottom of the sewage collecting tank 41. In this way, the sewage extraction port 71 can better extract the filtered sewage, and avoid the situation where too much sewage is accumulated in the sewage collecting part 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 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] According to another aspect of the utility model, a cleaning sweeper is provided, comprising the cleaning structure provided above.

[0093] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps 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 relationship. 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 description. In all the examples shown and discussed here, any specific values 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 in subsequent drawings is not necessary.

[0094] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc., 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 terms 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 terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

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

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