The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present application.

In the related art, the cleaning device comprises at least two driving rollers which are spaced apart from each other and a wiping belt wound on the driving rollers, and the motor drives the driving rollers to rotate so as to drive the wiping belt to wipe the ground, thereby realizing automatic cleaning of the ground. In addition, when brushing the wiping belt after wiping the floor, the wiping belt is generally immersed in water in a water tank and passed through a brushing member to brush the wiping belt. However, the existing brushing member has a single operation speed and poor brushing effect.

According to the cleaning device provided by the embodiment of the invention, the running speed of the brushing assembly can be adjusted, and the brushing effect is good.

The cleaning device according to the present application is described below with reference to the accompanying drawings.

As shown in fig. 6, 8, 9 and 11, the cleaning device 1 according to the present application includes a cleaning member, an endless conveying member 11, a brushing assembly 14 and an adjusting assembly 15. Wherein the cleaning members are provided on the endless conveying member 11 to circulate and convey the cleaning members between the first position and the second position by the endless conveying member 11. In the first position, the cleaning member cleans the floor. A brushing assembly 14 is located below the endless conveyor member 11 adjacent to the second position for brushing the cleaning elements.

The cleaning member is connected to the endless conveying member 11, and the cleaning member circulates continuously between a first position in which the cleaning member is adapted to contact the floor while cleaning dirt on the floor and wiping the floor, and a second position in which the cleaning member is adapted to contact the floor. The cleaning member is driven by the annular conveying part 11 to move continuously after passing through the first position, so that the cleaning member is brushed by the brushing assembly 14.

The adjustment assembly 15 includes a wringer plate 151, the wringer plate 151 and the endless conveying member 11 being spaced apart from each other. The wringer plate 151 is movable to adjust a gap between the wringer plate 151 and the endless conveying member 11.

The wringing plate 151 is provided at the rear of the upper side of the endless conveying member 11. After passing through the brushing assembly 14, the moving direction of the cleaning member is changed, namely, the cleaning member moves from bottom to top, passes through the brushing assembly 14, is brushed by the brushing assembly 14 and then moves from top to bottom. The squeezing plate 151 is adapted to squeeze the cleaning member to drain the excessive water from the cleaning member, reduce the water absorption of the cleaning member, prevent the cleaning member from bringing a large amount of water to the ground, and improve the cleaning effect of the cleaning device 1.

The wringing plate 151 is movable to change the gap through which the cleaning member passes, and can adjust the humidity of the cleaning member, i.e., control the amount of water squeezed from the cleaning member, so that the humidity of the cleaning member can be adapted to effectively clean different bottom surfaces, thereby improving the convenience of the cleaning device 1. While users typically need to mop the floor with a wet mop when they begin to clean the floor, and finally wipe the floor with a dry mop. Therefore, the cleaning device provided by the application can enable a user to automatically adjust the dry humidity according to the needs, thereby meeting the requirements of various cleaning scenes such as wet mopping, dry wiping and the like.

The lower end of the wringing plate 151 is provided with an extension part 152, and the wringing plate 151 can move to enable the extension part 152 to be contacted with or separated from the brushing assembly 14 so as to adjust the running speed of the brushing assembly 14, thereby achieving good brushing effect.

The lower end of the wringer plate 151 has an extension 152 and the brush assembly 14 includes a brush member 142, the wringer plate 151 being movable to bring the extension 152 into contact with the brush member 142 to adjust the rotational speed of the brush member 142.

As shown in fig. 10-12 and 17, in one embodiment of the present application, the brush member 142 may comprise a brush shaft provided with brushes uniformly spaced circumferentially for brushing the cleaning block 12. The brush shaft extends in the lateral direction, and when the wringer plate 151 moves toward the front side, the extending portion 152 interferes with the brush on the brush shaft. However, since the brush is a flexible member, the rotation of the brush shaft is not directly stopped, and the extension 152 generates resistance to the brush shaft, thereby reducing the rotation speed of the brush shaft. Further, by moving the wringer plate 151, the contact area between the extension 152 and the brush is increased or decreased, and thus the rotation speed of the brushing shaft is adjusted.

In addition, the brushing shaft is not limited to be provided with a brush, and other flexible parts such as sponge or cotton cloth can be provided, so long as the aim of cleaning the cleaning block can be achieved.

According to the cleaning device 1 of the present application, a wringing plate which can be close to or far from the annular conveying member 11 is provided, and an extension portion 152 is provided at the lower end of the wringing plate 151, and the distance between the wringing plate 151 and the annular conveying member 11 is controlled to adjust the resistance of the extension portion 152 to the brushing member 142, so as to adjust the rotation speed of the brushing member 142, and a user can adjust the rotation speed of the brushing member 142 according to the requirement, so that the brushing member 142 can brush the cleaning member better, and the cleaning effect of the cleaning device 1 is improved.

According to some embodiments of the application, the longitudinal extension of the endless transport member 11 (longitudinal direction in fig. 1 and 2) is arranged obliquely with respect to the horizontal plane, said second position being higher than said first position. The annular conveying part 11 is obliquely arranged, so that on the one hand, the contact area between the cleaning block 12 and the ground can be improved, the contact time between the cleaning block 12 and the ground is shortened, the cleaning block 12 is in contact with the ground only when moving to the lowest point (namely, the first position) in the annular conveying part 11, the moving direction of the cleaning block 12 can be changed when moving to the lowest point, the cleaning block 12 cleans garbage on the ground towards the cleaning device 1, and the cleaning block 12 is retracted into the cleaning device 1 after being in contact with the ground, so that the cleaning block 12 effectively cleans the ground, the cleaning block 12 which is in contact with the ground is prevented from being in contact with the ground again, invalid cleaning is prevented, and pollution to the cleaned ground is reduced.

In some embodiments of the application, the cleaning elements are cleaning blocks 12 having a generally rectangular, circular or oval cross-sectional area.

The cleaning device of the present application will be described in detail with reference to fig. 1 to 22.

The cleaning device 1 according to the application comprises at least one endless conveyor member 11 and at least one cleaning block 12, the endless conveyor member 11 being operable at the same speed in the circumferential direction of the endless conveyor member 11. The cleaning block 12 is mounted on the endless conveying member 11 and is moved by the endless conveying member 11 in the circumferential direction of the endless conveying member 11 to clean a surface to be cleaned, such as a floor.

In the related art, the cleaning device is provided with a driving roller and a driven roller, an annular integral wiping cloth sleeve surrounds the driving roller and the driven roller, and the width of the integral wiping cloth sleeve is approximately consistent with the axial length of the driving roller and the driven roller. However, because the contact force between the integral cloth cover and the roller is inconsistent, the force applied by the roller to the rag is also uneven, so the integral cloth cover is easy to deform and is not easy to replace and clean. Under the condition that the rag cover is distorted, the stress of each position of the rag cover is uneven when the rag cover contacts with the ground, the further deformation of the rag cover is easily caused, and the rag cover is not synchronous with the driving roller and the driven roller, so that the rag cover is damaged.

According to the cleaning device 1 of the present application, by mounting the cleaning block 12 on the endless conveying member 11, the cleaning block 12 is capable of cleaning a surface to be cleaned such as a floor surface, and the cleaning block 12 facilitates replacement cleaning. And the cleaning block 12 and the annular conveying part 11 can realize synchronous movement, so that the cleaning effect is better. And the cleaning block 12 is not easy to distort and deform, has longer service life and is not easy to damage.

In one embodiment of the present invention, the number of endless conveying members 11 is one, as shown in fig. 21. In this embodiment, one or more cleaning blocks 12 are mounted on the endless conveyor member, and rotation of the one endless conveyor member 11 moves one or more cleaning blocks 12 mounted thereon in synchronism.

In one embodiment of the present invention, the number of endless conveying members 11 is two or more, as shown in fig. 1. In the present invention, the number of the endless conveying members 11 is not limited, and any one of two or more numbers may be set as required. Two or more endless conveying members 11 are moved synchronously at the same speed, and one part of one cleaning block 12 is mounted on one endless conveying member 11 and the other part of one cleaning block 12 is mounted on the other endless conveying member 11, so that different parts of each cleaning block 12 are moved at the same speed, thereby ensuring that each cleaning block 12 does not twist. The synchronous movement between the two or more endless conveying members 11 will be achieved by a timing belt or chain, as described below, connected to a driving wheel and a driven wheel, as will be described in detail below.

In summary, at least one endless conveying member 11 as a whole moves in its circumferential direction at the same speed.

It will be appreciated that the circumferential length of the cleaning blocks 12 is less than or equal to the circumferential length of the endless conveyor means 11.

Further, the cleaning block 12 is detachably mounted on the endless conveying member 11 to further facilitate replacement cleaning thereof.

According to one embodiment of the present application, a plurality of cleaning blocks 12 are arranged at intervals along the circumferential direction of the endless conveying member 11. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

A plurality of cleaning blocks 12 are mounted on the endless conveying member 11, the plurality of cleaning blocks 12 are arranged at intervals along the circumferential direction of the endless conveying member 11, and the plurality of cleaning blocks 12 are not connected to each other. When the cleaning device 1 is in operation, a single cleaning block 12 cleans the floor, the contact area between the cleaning block 12 and the floor is small, and the friction force is small. Each independent cleaning block 12 can clean the ground more stably, the cleaning blocks 12 are not easy to damage, and the service life of the cleaning blocks 12 is prolonged.

According to the cleaning device 1 of the present application, by arranging the plurality of cleaning blocks 12 at intervals along the circumferential direction of the endless conveying member 11, each cleaning block 12 individually cleans the floor surface when the cleaning device 1 is in operation, and each cleaning block facilitates individual replacement cleaning. Each cleaning block 12 is evenly stressed at each position when being contacted with the ground, the cleaning blocks 12 can be effectively prevented from being deformed, the service life of the cleaning blocks 12 is longer, and the cleaning blocks are not easy to damage. Each cleaning block 12 moves synchronously with the endless conveying member 11, and the cleaning effect is better.

The plurality of cleaning blocks 12 are arranged at intervals along the circumferential direction of the endless conveying member 11, the gap between the adjacent two cleaning blocks 12 is increased, and dirt such as dust is prevented from accumulating in the gap between the adjacent two cleaning blocks 12. In addition, the two adjacent cleaning blocks 12 are arranged at intervals, so that acting force generated between the two adjacent cleaning blocks 12 can be avoided, the cleaning blocks 12 can be kept synchronous with the movement of the annular conveying part 11 better, the service life of the cleaning blocks 12 is further prolonged, and damage to the cleaning blocks 12 is avoided.

Further, the plurality of cleaning blocks 12 are arranged at regular intervals in the circumferential direction of the endless conveying member 11, that is, the distances between the adjacent cleaning blocks 12 are the same.

According to one embodiment of the present application, the distance between adjacent cleaning blocks 12 is 20 mm-800 mm. When the distance between two adjacent cleaning blocks 12 is set to 20 mm, it is possible to ensure that the cleaning blocks 12 have a sufficiently high density in the circumferential direction of the endless conveying member 11, and to improve the frequency of cleaning of the floor by the cleaning device 1, thereby improving the cleaning effect. When the distance between two adjacent cleaning blocks 12 is set to 800 mm, the number of the cleaning blocks 12 arranged on the endless conveying member 11 can be reduced, and the cost of the cleaning apparatus 1 can be reduced. At the same time, the cleaning effect of the cleaning device on the floor can be maintained by increasing the rotational speed of the endless conveying member 11. It will be appreciated that the distance between two adjacent cleaning blocks 12 of the cleaning device 1 of the present application is not limited thereto, and the distance between two adjacent cleaning blocks 12 is based on actual requirements.

According to an embodiment of the present application, the cleaning apparatus 1 further includes a driving wheel 110 and a driven wheel 120, the driven wheel 120 and the driving wheel 110 being arranged at intervals in a longitudinal direction, a center line of the driven wheel 120 and the driving wheel 110 extending obliquely upward from a center of the driven wheel 120 with respect to a horizontal direction.

The endless conveying member 11 is wound around the driving pulley 110 and the driven pulley 120, and the cleaning block 12 has a lateral extension longer than the axial length of the driving pulley 110 and the axial length of the driven pulley 120. In other words, as shown in fig. 1, the axial lengths of the driving wheel 110 and the driven wheel 120 are relatively short, and the length of the cleaning block 12 in the lateral direction is much longer than the axial length of the driving wheel 110 and the axial length of the driven wheel 120, and the length of the cleaning block 12 in the lateral direction is also much longer than the lateral extension length of the endless conveying member 11 (the length of the endless conveying member 11 in the lateral direction).

In the present embodiment, the driving wheel 110, the driven wheel 120, and the endless conveying member 11 constitute a transmission mechanism that allows one endless conveying member 11 to move stably and reliably at a specific speed or allows a plurality of endless conveying members 11 to move at the same speed, thereby ensuring that the endless conveying members 11 move synchronously and stably as a whole. The driving wheel 110 is located at the rear side in the longitudinal direction of the driven wheel 120 at the upper side in the vertical direction, and the cleaning block 12 is mounted on the endless conveying member 11 by a small portion (for example, in the case of including two endless conveying members 11, it is preferable that the cleaning block 12 is mounted on the two endless conveying members 11 by the first and second ends thereof), so that the cleaning block 12 is in contact with the transmission mechanism by a small portion and is not in contact with the transmission roller over a large area as in the prior art. Thus, as long as it is ensured that the parts of the cleaning block 12 connected to the endless conveying member 11 move at the same speed, the force exerted by the endless conveying member 11 on these connected parts of the cleaning block 12 is uniform. Therefore, each part of the cleaning block 12 can synchronously move, is not easy to twist, has long service life and has better cleaning effect. However, in the prior art, the driving roller applies force to each part of the cleaning belt in the transverse direction, which tends to cause uneven force to each part of the cleaning belt in the transverse direction, thereby causing twisting. According to the cleaning device 1 of the present application, in the case of comprising an endless conveyor member 11, the cleaning block 12 moves in synchronization with the endless conveyor member 11. In the case of including a plurality of endless conveying members 11, since the plurality of endless conveying members 11 are synchronized with each other, the respective portions of one cleaning block 12 mounted thereon are also moved in synchronization. Therefore, in both cases, the cleaning block 12 is not distorted, and the cleaning effect is better.

The central line between the driving wheel 110 and the driven wheel 120 is inclined with respect to the horizontal direction, i.e. forms a certain angle with the ground, and the driving wheel 110 is disposed above the rear side of the driven wheel 120. Whereby the conveying track of the endless conveying member 11 has a certain inclination angle with the ground. Wherein the driven wheel 120 corresponds to the lower turning position of the track, and the driving wheel 110 corresponds to the upper turning position of the track. The cleaning block 12 contacts the floor when moved to the lower turn of the track to clean the floor.

Here, the direction from the driven wheel 120 toward the driving wheel 110 is defined as a front-to-back direction, wherein the front-to-back direction is the longitudinal direction. Since the cleaning block 12 is moved to a position where the driven wheel 120 is located to contact the floor for cleaning the floor, the position where the cleaning block 12 contacts the floor is at the front and the rest is at the rear.

According to one embodiment of the present application, as shown in fig. 1 to 6, the capstan 110 includes a first capstan 113 and a second capstan 114, and the first capstan 113 and the second capstan 114 are arranged at a lateral interval. The driven pulley 120 includes a first driven pulley 115 and a second driven pulley 116, and the first driven pulley 115 and the second driven pulley 116 are arranged at intervals in the lateral direction. The first driven wheel 115 is longitudinally spaced from the first drive wheel 113 and the second driven wheel 116 is longitudinally spaced from the second drive wheel 114.

A center line of the first driven wheel 115 and the first driving wheel 113 extends upward from a center of the first driven wheel 115 obliquely with respect to the horizontal direction, and a center line of the second driven wheel 116 and the second driving wheel 114 extends upward from a center of the second driven wheel 116 obliquely with respect to the horizontal direction.

The endless conveying member 11 includes a first endless conveying member 111 and a second endless conveying member 112, the first endless conveying member 111 being wound around a first driving wheel 113 and a first driven wheel 115, the second endless conveying member 112 being wound around a second driving wheel 114 and a second driven wheel 116, the first endless conveying member 11 and the second endless conveying member 112 being synchronously moved with respect to each other.

As shown in fig. 1 and 2, the first endless conveying member 111 and the second endless conveying member 112 are spaced apart in the lateral direction, the first endless conveying member 111 is sleeved on the first driving wheel 113 and the first driven wheel 115, and the first driving wheel 113 and the first driven wheel 115 are arranged at intervals in the longitudinal direction, and the first driving wheel 113 is located at the longitudinally rear side of the first driven wheel 115 and at the vertically upper side. The second annular conveying member 112 is sleeved on the second driving wheel 114 and the second driven wheel 116, and the second driving wheel 114 and the second driven wheel 116 are longitudinally arranged at intervals, and the second driving wheel 114 is positioned at the longitudinally rear side and the vertically upper side of the second driven wheel 116. The first end of the cleaning block 12 is fixed to the first endless conveyor 111, and the second end of the cleaning block 12 is fixed to the second endless conveyor 112. The first annular conveying member 11 and the second annular conveying member 112 move synchronously relative to each other, so that the cleaning block 12 can move stably and reliably, the floor can be cleaned circularly, the cleaning block 12 is not easy to distort and deform, and the service life is long.

The first end of the cleaning block 12 is connected to a first endless conveyor 111 and the second end of the cleaning block 12 is connected to a second endless conveyor 112. In the present disclosure, the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Wherein the first annular conveying member 111 and the second annular conveying member 112 may have the same shape, and the conveying track of the first annular conveying member 111 is identical to the conveying track of the second annular conveying member 112. After connecting the first and second ends of the cleaning block 12 to the first and second endless conveying members 111 and 112, respectively, the cleaning block 12 can be moved with the movement of the first and second endless conveying members 111 and 112.

Preferably, as shown in fig. 6, 7, 11 and 12, the garbage collection plate 131 includes a first member 1311 and a second member 1312 provided on the first member 1311. The upper end face and the lower end face of the first member 1311 are both disposed horizontally, and the front end face of the first member 1311 is disposed obliquely upward with respect to the horizontal plane in the front-to-rear direction, and the inclination angle is the same as that of the endless conveying member 11.

The second member 1312 includes a first plate 13121 and a second plate 13122, the first plate 13121 being provided at an upper end face of the first member 1311, the second plate 13122 being provided obliquely upward from a front end of the first plate 13121 in a front-to-rear direction, and at the same angle as that of the endless conveying member 11, so that an upper surface of the second plate 13122 is on the same plane as the front end face of the first member 1311. In addition, an extension plate 13123 is further provided on the lower surface of the second plate 13122, and a socket 13124 is formed between the extension plate 13123 and the first plate 13121.

Wherein the first member 1311 may be a flexible material such as a sponge and the second member 1312 may be a rigid material.

Preferably, as shown in fig. 13 and 14, the waste bin 132 includes a body 1321 and an upper cover 1322, the upper cover 1322 being pivotally connected to the body 1321 to open and close the body 1321. In other words, the upper cover 1322 is rotatable between an open position that opens the body 1321 and a closed position that closes the body 1321. Wherein in the closed position the upper cover 1322 may engage the front side of the waste collection plate 131, i.e. the upper surface of the upper cover 1322 is in the same plane as the upper surface of the second plate 13122, the front face of the first member 1311. Preferably, in the closed position, the cross section of the waste bin 132 is a right triangle and the upper cover 1322 is located at the position of the hypotenuse of the right triangle.

As shown in fig. 12 and 13, when the upper cover 1322 is in the closed position, the garbage can pass through the front end surface of the first member 1311, the upper surface of the second plate 13122, and the upper surface of the upper cover 1322 in order, and enter the garbage box 132, under the driving of the cleaning block 12.

As shown in fig. 12-14, the garbage collection assembly 13 further comprises a cleaning member 133, the cleaning member 133 being provided in the garbage can 132 for cleaning dirt on the cleaning block 12 into the garbage can 132, according to an embodiment of the present application. When the cleaning block 12 moves above the trash box 132, the cleaning piece 133 contacts the surface of the cleaning block 12. The cleaning member 133 rubs against the surface of the cleaning block 12 by the endless conveying member 11 to brush down dirt on the cleaning block 12 and drop the dirt into the dust box 132.

The cleaning member 133 may be configured as a plurality of brushes arranged in a lateral direction, the brushes being disposed in the trash box 132, and free ends of the brushes being in contact with the surface of the cleaning block 12. It is understood that the present application is not limited thereto, and that the cleaning member 133 may be configured as a toothed scraper, a roughened cotton cloth, or other cleaning member such as a plastic brush, for example.

According to one embodiment of the application, as shown in fig. 12, 15 and 16, the cleaning device 1 further comprises a brushing assembly 14, the brushing assembly 14 being adjacent to the first end of the endless conveying member 12, which is high relative to the horizontal plane, for brushing the cleaning block. As shown in fig. 12, 15 and 16, the brushing assembly 14 is positioned behind the trash box 132 for brushing the cleaning block 12. After the cleaning block 12 passes through the bin 132, a majority of the dirt falls into the bin 132. When the cleaning block 12 moves to the upper end of the annular conveying part 11, the brushing assembly 14 brushes the cleaning block 12 and cleans and humidifies the cleaning block 12, so that the cleaning block 12 can effectively wipe and clean the ground in the next contact process with the ground, and the scrubbing quality of the cleaning block 12 on the ground is improved.

According to one embodiment of the application, the brush assembly 14 includes a water reservoir 141 and a brush 142, the water reservoir 141 being located below the first end of the endless conveying member 11. The brushing member 142 is disposed in the water tank 141 and adjacent to the second position, the brushing member 142 is rotatable under the driving of the cleaning member for brushing the cleaning member, and the wringer plate 151 is movable to contact the extension 152 with the brushing member 142 so as to adjust the rotation speed of the brushing member 142. The brush 142 rotates to drive the water in the water tank 141 so that the water in the water tank 141 can be sprayed to the surface of the cleaning block 12. In other words, the cleaning block 12 is not directly contacted with the water in the water tank 141, but water is sprayed to the cleaning block 12 through the brush 142. The brush 142 may also contact the cleaning block 12 as it rotates to brush the surface of the cleaning block 12.

As shown in fig. 11 and 16, the water tank 141 is located at the rear of the waste bin 132. The brush 142 is disposed within the water reservoir 141, and water within the water reservoir 141 submerges a portion of the brush 142 in the water, and another portion of the brush 142 is above the water surface and is contactable with the cleaning block 12. Thus, the brushing member 142 is rotated to drive the water in the water tank 141 to be sprayed onto the cleaning block 12, so that the cleaning block 12 can be wetted without directly contacting the cleaning block 12, and the cleaning block 12 can be brushed by contacting the cleaning block 12.

It will be appreciated that the rotation of the brush member 142 may also be driven solely by the power means, and the application is not limited thereto.

The water tank 141 is provided with cleaning water, at least part of the brushing member 142 can be positioned below the liquid level of the water tank 141, and the brushing member 142 can drive the water in the water tank 141 when rotating, so that the water in the water tank 141 splashes onto the cleaning block 12 to improve the humidity of the cleaning block 12. The brush 142 may also be in contact with the cleaning block 12 to brush clean the cleaning block 12.

According to the cleaning device 1 of the embodiment of the application, the brushing member 142 can rotate under the driving of the cleaning block 12 to spray water to the cleaning block 12 and brush the cleaning block 12. The water in the water tank 141 can be sufficiently used to brush the cleaning block 12 without frequent replacement of the water in the water tank 141. The brushing piece 142 has better brushing effect on the cleaning block 12, the cleanliness of the cleaning block 12 is higher, the utilization efficiency of water resources is improved, the number of water changing times of the cleaning device 1 is reduced, the purpose of saving the water resources is achieved, and meanwhile, the use experience of a user is improved.

The inventors have found through numerous experiments that in the case of directly immersing the cleaning block 12 in water, even if the rotational speed of the motor is set low, the cleaning block 12 cannot obtain a relatively ideal dry humidity by the wringing device, and therefore, the inventors have abandoned the manner of directly immersing the cleaning block 12 in water, but used a spray water manner to wet the cleaning block 12. Therefore, by adopting the cleaning device, the water supply amount to the rag and the cleaning of the rag can be automatically adjusted in a later period conveniently by adopting an indirect water supply mode.

As shown in fig. 15 and 17, the brush assembly 14 further includes a first barrier 143 and a second barrier 144, the first barrier 143 being provided at an upper end of the water tank 141, the first barrier 143 being located below the endless conveying member 11 and being located at a first side of the brush 142 in a longitudinal direction, according to an embodiment of the present application. The second baffle 144 is disposed at an upper end of the water tank 141, and the second baffle 144 is located at a second side of the brush 142 in the longitudinal direction.

According to one embodiment of the application, the first baffle 143 extends in the length direction of the endless conveying member 11 and the second baffle 144 extends in the horizontal direction.

Wherein, as shown in fig. 17, the first side may be a front side of the brush 142, and the second side may be a rear side of the brush 142. The first and second baffles 143 and 144 serve to prevent the cleaning water from splashing into the interior of the cleaning device 1 when the brush 142 rotates. A cleaning gap is left between the first barrier 143 and the second barrier 144, which is adapted for the brushing member 142 to contact the cleaning block 12, and the brushing member 142 is adapted to brush and humidify the cleaning block 12 when the cleaning block 12 passes through the cleaning gap. The first baffle 143 extends along the length direction of the annular conveying part 11, the inclination angle is the same as that of the annular conveying part 11, and the front side of the first baffle 143 can be connected with the upper side wall of the garbage box 132, so that the cleaning block 12 is ensured to move stably. The second baffle 144 extends in a horizontal direction and is disposed at an upper side of the water tank 141, and prevents dirt from falling into the water tank 141. The provision of the first and second baffles 143 and 144 also prevents water in the water tank 141 from splashing into the interior of the cleaning apparatus 1 under the rotation of the brush 142.

According to one embodiment of the application, as shown in fig. 10-12, the cleaning device 1 further comprises an adjustment assembly 15, the adjustment assembly 15 being arranged above the brushing elements 142 and spaced apart from the endless conveying member 11 for adjusting the humidity of the cleaning block 12. According to the cleaning device 1 of the embodiment of the present application, the humidity of the cleaning block 12 can be adjusted, that is, the amount of water squeezed from the cleaning block 12 is controlled, by providing the adjusting assembly 15, so that the humidity of the cleaning block 12 can be adapted to more effectively clean different floors, thereby improving the convenience of the cleaning device 1.

According to one embodiment of the application, the adjustment assembly 15 comprises a wringer plate 151, the wringer plate 151 and the annular conveying member 11 being arranged spaced apart from each other, the wringer plate 151 being movable to adjust the gap between the wringer plate 151 and the annular conveying member 11. Thus, by providing the movable wringer plate 151, the gap between the wringer plate 151 and the endless conveying member 11 can be adjusted, and the wringer plate 151 can be brought into contact with the brush assembly 14 to adjust the operating speed of the brush assembly 14.

As shown in fig. 12 and 17, a wringer plate 151 is provided at the rear of the upper side of the endless conveying member 11, and after the cleaning block 12 passes through the water tank 141, the cleaning block 12 starts to move from top to bottom after bypassing the capstan, and the wringer plate 151 is adapted to squeeze the cleaning block 12 after the cleaning block 12 bypasses the capstan. The transmission shaft 117 can be matched with the wringing plate 151 to drain the excessive water in the cleaning block 12, reduce the water absorption of the cleaning block 12, prevent the cleaning block 12 from bringing a large amount of water to the ground, and improve the cleaning effect of the cleaning device 1. In one embodiment of the present application, extrusion protrusions extending outwards in the radial direction of the transmission shaft 117 are uniformly arranged at intervals on the outer circumference of the transmission shaft 117, the extrusion protrusions are suitable for extruding the inner side of the cleaning block 12, the arrangement of the extrusion protrusions can improve the friction between the transmission shaft 117 and the cleaning block 12, the cleaning block 12 can smoothly bypass the transmission shaft 117, and meanwhile, the extrusion protrusions can be matched with the wringing plate 151 to improve the wringing effect on the cleaning block 12.

According to one embodiment of the present application, the lower end of the wringer plate 151 has an extension 152, and the wringer plate 151 is movable to bring the extension 152 into contact with or out of contact with the brush 142 to adjust the rotational speed of the brush 142, thereby controlling the amount of water supplied from the brush 142 to the cleaning block 12 and/or the brushing speed. It will be appreciated that the rotational speed of the brush 142 varies, the amount of water supplied to the cleaning block 12 by the brush 142 varies, and the dry and wet degree of the cleaning block 12 varies.

Therefore, by adopting the cleaning device, a user can automatically and further adjust the dry humidity according to the needs, and the requirements of various cleaning scenes such as wet mopping, dry wiping and the like are met.

According to one embodiment of the present application, the adjusting assembly 15 further includes a cam 153, the outer circumference of the cam 153 being in contact with the wringer plate 151, the cam 153 being rotatable to drive the wringer plate 151 to be movable.

Specifically, the cam 153 is disposed at the rear side of the wringer plate 151, and the rotation center of the cam 153 is perpendicular to the horizontal plane. The outer circumference of the cam 153 is always kept in abutment with the wringer plate 151, and since the distance between the outer circumference of the cam 153 and the center of the cam 153 is different, the outer circumference of the cam 153 can push the wringer plate 151 to move under the rotation of the cam 153 so as to adjust the distance between the wringer plate 151 and the annular conveying member 11, thereby adjusting the degree of extrusion to the cleaning block 12. The extension 152 at the lower end of the wringing plate 151 contacts the brushing member 142, and the rotating cam 153 can change the contact area between the extension 152 and the brushing member 142, so as to adjust the rotation speed of the brushing member 142.

It is understood that the outer circumferential surface of the cam 153 has a plurality of surfaces along the circumferential direction of the cam 153, and the distances between the plurality of surfaces and the rotation center of the cam 153 are different, so that the rotation of the cam 153 may drive the displacement of the wringer plate 151. The number of different surfaces of the outer circumferential surface of the cam 153 may be set according to actual needs, and the distances between the different surfaces and the rotation center may also be set according to actual needs, which is not limited by the present application.
