Referring to fig. 2, fig. 2 is a schematic cross-sectional structure of a filter according to an embodiment of the application.

In one embodiment, the filter 30 includes a filter portion 31, where the filter portion 31 is disposed on a side of the extrusion 20 near the surface to be cleaned, and the filter portion 31 includes a first portion 311, a second portion 312, and a third portion 313 that are connected by bending, where the first portion 311 is disposed opposite to the third portion 313, and the first portion 311 is near the cleaning roller 10 opposite to the third portion 313.

The second portion 312 is provided with at least one first filter hole 341 and the third portion 313 is provided with at least one second filter hole 342.

The filter portion 31 is provided on a side of the pressing member 20 near the surface to be cleaned, in other words, the filter portion 31 is provided below the pressing member 20. When the pressing member 20 presses the cleaning roller 10, substances such as sewage and impurities adsorbed by the cleaning roller 10 drop due to its own weight, and the filtering portion 31 is provided below the pressing member 20 so as to receive the substances such as sewage and impurities and filter the substances such as sewage and impurities.

In the present embodiment, the second portion 312 is provided with at least one first filter hole 341 and the third portion 313 is provided with at least one second filter hole 342. The number of the first filter holes 341 and the second filter holes 342 is not limited in the present application, and may be adjusted according to the specification of the cleaning device 1.

In the working process of the cleaning device 1, if the large impurities on the surface to be cleaned are more, the first filtering holes 341 of the second portion 312 are easy to be blocked, and the third portion 313 is provided with at least one second filtering hole 342, so that the sewage is filtered out from the second filtering holes 342, and the filtering efficiency of the filtering portion 31 is improved.

In other embodiments, the third portion 313 may also be provided with a plurality of filter holes 34, which are not limited by the present application.

Referring to fig. 2, in an embodiment, the filter 30 further includes an extension portion 32, where the extension portion 32 is disposed on the third portion 313 and extends toward a direction away from the surface to be cleaned, the extension portion 32 is disposed on a side of the extrusion 20 away from the cleaning roller 10, and an end of the extension portion 32 away from the surface to be cleaned is farther away from the surface to be cleaned than the extrusion 20.

The filter 30 further includes a baffle 33, the baffle 33 is disposed at an end of the extension 32 facing away from the surface to be cleaned, and the baffle 33 extends in a direction approaching the pressing member 20.

When the pressing member 20 abuts and presses the cleaning drum 10, a part of the contaminated water in the cleaning drum 10 may be splashed. The extension 32 is disposed on the third portion 313 and extends in a direction away from the surface to be cleaned, the extension 32 is disposed on a side of the extrusion 20 away from the cleaning roller 10, and the extension 32 can be used to block the dirty water splashed when the extrusion 20 extrudes the cleaning roller 10 and to allow the dirty water to flow to the third portion 313 and the second portion 312 for filtering. Further, when the sewage falls to the second portion 312 of the filtering portion 31, a splash phenomenon may also occur, and the blocking portion may also be used to block the sewage that splashes after falling to the second portion 312.

The baffle 33 extends in a direction approaching the pressing member 20, and the baffle 33 is connected to the extension 32 by bending. The baffle 33 may also be used to block splatter waste water as the extrusion 20 presses against the cleaning drum 10 or splatter waste water after it falls to the second portion 312.

In the filter member 30 provided by the application, the filtering part 31 is arranged on one side of the extrusion 20 close to the surface to be cleaned, the extension part 32 is arranged on one side of the extrusion 20 away from the cleaning roller 10, the baffle 33 is arranged on one side of the extrusion 20 away from the surface to be cleaned, the filtering part 31, the extension part 32 and the baffle 33 of the filter member 30 are connected, and the filter member 30 surrounds the extrusion 20 away from the outer periphery of the cleaning roller 10, so that most of sewage and impurities extruded by the extrusion 20 can be filtered through the filter member 30.

Referring to fig. 3, fig. 3 is a schematic cross-sectional view of a cleaning roller, an extrusion member, and a filter member according to another embodiment of the application.

In this embodiment, the cleaning apparatus 1 further includes a baffle 83, one end of the baffle 83 being connected to the filter member 30, and the other end extending in a direction approaching the pressing member 20.

The baffle 83 may be used to drain the dirt and impurities expressed by the extrusion 20 and to drain the dirt and impurities from the upper end of the extrusion 20 into the filter element 30. The large garbage is directly introduced into the filter member 30 from the upper surface of the baffle 83, and part of the sewage and foreign matters extruded from the extrusion member 20 can also flow into the filter member 30 from below through the holes of the baffle 83. This prevents the extrusion 20 from being stuck or entangled by the large trash.

In the related art, the cleaning roller of the cleaning device extrudes the sewage inside the cleaning roller by using the extruding scraping of sliding friction, which causes the load of the motor of the cleaning roller to be increased, and affects the service life of the motor of the cleaning roller. In addition, the manufacturing process of the cleaning roller is generally a pouring and foaming process, the cleaning roller manufactured by the process is poor in precision, the size of the cleaning roller and the hardness degree of the self structure are inconsistent, and the load of a roller motor is also influenced.

In one embodiment, the extrusion 20 is capable of rotating against the cleaning drum 10, and the direction of rotation of the extrusion 20 is opposite to the direction of rotation of the cleaning drum 10.

For example, in one embodiment, the cleaning roller 10 abuts the extrusion 20 and forms a deformation groove 11, the deformation groove 11 having a maximum depth in the range of 1mm to 8mm.

Alternatively, the maximum depth of the deformation groove 11 may be 1mm, or 2mm, or 3mm, or 3.3mm, or 3.7mm, or 4.0mm, or 4.5mm, or 5mm, or 6mm, or 7mm, or 8mm, or other values within 1mm-8mm. Alternatively, the maximum depth of the deformation groove 11 may be in other ranges, such as 2mm-4mm, or 2.5mm-6mm, or 3.5mm-7mm, or other ranges, and should not be construed as limiting the present application.

In one embodiment, the extrusion 20 may also be an active rotating structure, and the direction of rotation of the extrusion 20 is the same as the direction of rotation of the cleaning drum 10. The rotation direction of the extrusion piece 20 is the same as the rotation direction of the cleaning roller 10, so that when the extrusion piece 20 extrudes sewage and impurities of the cleaning roller 10, the extrusion piece 20 drives the sewage and the impurities to move along the rotation direction of the extrusion piece 20, and then the sewage and the impurities are taken away from the extrusion part of the extrusion piece 20 and the cleaning roller 10, so that the extrusion effect is prevented from being influenced by the impurities clamped at the extrusion part of the extrusion piece 20 and the cleaning roller 10.

In one embodiment, the extrusion 20 may be a fixed structure, in other words, the extrusion 20 may not rotate, which is not a limitation of the present application.

Referring to fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of a cleaning device including a sliding member according to an embodiment of the application, and fig. 6 is an enlarged schematic structural diagram of a sliding member sliding-connecting with a side wall of a housing according to an embodiment of the application.

In one embodiment, the cleaning device 1 further includes a housing 40 and a sliding member 50, a first through hole 401 is disposed on a side wall of the housing 40, the pressing member 20 is rotatably connected to the sliding member 50, at least a portion of the sliding member 50 is slidably connected to an inner wall of the first through hole 401 along a preset direction, the preset direction is a direction approaching or separating from an axis of the cleaning roller 10, and the sliding member 50 is used for driving the pressing member 20 to move along the preset direction.

The housing 40 has a first receiving space therein for receiving the cleaning roller 10, the pressing member 20, the filter member 30, and other structural members.

In one embodiment, the side wall of the housing 40 includes a side wall body 41, a side plate 42, and a side cover plate, the side wall body 41 is connected to the side plate 42 in a bending manner, the side plate 42 is provided with the first through hole 401, the peripheral side of the side cover plate abuts against the side plate 42, and the side wall body 41, the side plate 42, and the side cover plate enclose a second accommodating space.

The side wall of the housing 40 is provided with a first through hole 401, and at least part of the sliding member 50 is slidably connected with the inner wall of the first through hole 401 along a preset direction. And one end of the slider 50 abuts against the inner wall of the first through hole 401, and the other end of the slider 50 abuts against the side cover plate to restrict the movement of the slider 50 in a direction parallel to the axis of the cleaning drum 10.

In other embodiments, the sliding member 50 may have a groove portion that engages with the inner wall of the first through hole 401, so that the sliding member 50 can only slide along the extending direction of the inner wall of the first through hole 401, and the connection structure between the sliding member 50 and the inner wall of the first through hole 401 is not limited in the present application, as long as the sliding member 50 can slide along the preset direction.

The sliding member 50 moves in a predetermined direction and drives the pressing member 20 in the predetermined direction to adjust the depth to which the pressing member 20 presses the cleaning roller 10. When the radial dimension of the cleaning roller 10 is changed due to the manufacturing error, the slider 50 may drive the pressing member 20 to move in a preset direction so that the pressing member 20 presses the cleaning roller 10 to the same depth. For example, if the radial dimension of the cleaning roller 10 is reduced due to the manufacturing error, the sliding member 50 may drive the pressing member 20 to move in a direction approaching the axis of the cleaning roller 10; if the radial dimension of the cleaning cylinder 10 increases due to manufacturing tolerances, the slider 50 may move the extrusion 20 in a direction away from the axis of the cleaning cylinder 10.

The elastic member 60 is used for providing elastic supporting force to the sliding member 50, and enabling the sliding member 50 to drive the extrusion 20 to move along the direction approaching to the axis of the cleaning roller 10 and abut against the cleaning roller 10. Accordingly, the pressing depth of the pressing member 20 with the cleaning roller 10 is determined by the supporting force of the elastic member 60, in other words, the pressing depth of the pressing member 20 with the cleaning roller 10 is determined by the elastic force set value of the elastic member 60. If the supporting force provided by the elastic member 60 is large, the pressing depth of the pressing member 20 with the cleaning roller 10 is large; if the supporting force provided by the elastic member 60 is small, the pressing depth of the pressing member 20 with the cleaning cylinder 10 is small.

The pressing depth of the pressing member 20 with the cleaning roller 10 is determined by the supporting force of the elastic member 60, and thus, when the radial dimension of the cleaning roller 10 in the cleaning apparatus 1 is changed, the pressing depth of the pressing member 20 with the cleaning roller 10 is kept constant. It should be noted that the radial dimension of the cleaning roller 10 may be changed, including, but not limited to, due to errors in manufacturing accuracy or due to the need to assemble cleaning rollers 10 of different specifications, or other reasons.

Alternatively, in the present embodiment, the elastic member 60 is a spring, and in other embodiments, the elastic member 60 may be other elastic members, such as a leaf spring, a silicone member, or other elastic members.

In other embodiments, the sliding distance of the sliding member 50 from one end of the sliding groove 423 to the other end of the sliding groove 423 may be 2.5mm-4.5mm, or 3mm-5mm, or 3.5mm-6mm, or other ranges, which is not limited by the present application.
