Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application. In the description of the present application, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and to simplify the description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the present application.

In the related art, the cleaning device includes at least two driving rollers spaced apart from each other and a wiping belt wound around the driving rollers, and the motor drives the driving rollers to rotate to drive the wiping belt to wipe the floor, thereby achieving automatic cleaning of the floor. In addition, when brushing the wiping tape after wiping the floor, the wiping tape is usually immersed in water in a water tank and passed through a brush member to brush the wiping tape. However, the prior brushing member has single running speed and poor brushing effect.

According to the utility model discloses cleaning device can adjust the functioning speed who brushes the subassembly, brushes effectually.

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 annular conveying member 11, a brush assembly 14 and an adjusting assembly 15. Wherein the cleaning member is provided on the endless conveying member 11 to circulate the cleaning member between the first position and the second position by the endless conveying member 11. In the first position, the cleaning members 11 clean the floor. The brush assembly 14 is located below the endless conveyor member 11 and adjacent the second position for brushing the cleaning elements.

The cleaning elements are connected with the annular conveying component 11, and continuously circulate between a first position and a second position along with the annular conveying component 11, and the cleaning elements are suitable for contacting with the ground when in the first position, and simultaneously cleaning dirt on the ground and wiping the ground. After passing through the first position, the cleaning member continues to move under the driving of the annular conveying component 11, so that the cleaning member is brushed by the brushing component 14.

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

The wringer plate 151 is provided at the rear of the upper side of the endless conveying member 11. After the cleaning member passes through the brushing assembly 14, the moving direction of the cleaning member changes, i.e. the cleaning member moves from bottom to top and passes through the brushing assembly 14, and then moves from top to bottom after being brushed by the brushing assembly 14. The wringing plate 151 is suitable for squeezing the cleaning member to discharge excess water in the cleaning member, reduce the water absorption amount 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 vary 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 out of 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 apparatus 1. The user typically begins cleaning the floor with a large water wipe and finally wipes the floor with a dry wipe. Therefore, by adopting the cleaning device, the user can automatically adjust the dry humidity according to the requirement, and the requirements of various cleaning scenes such as wet mopping, dry wiping and the like can be met.

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 in contact with or separated from the brushing assembly 14, so that the running speed of the brushing assembly 14 can be adjusted, and the brushing effect is good.

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

As shown in fig. 10-12 and 17, in one embodiment of the present application, the brush 142 may include a brush shaft having brushes arranged at regular intervals in a circumferential direction thereof for brushing the cleaning block 12. The brushing shaft extends in the lateral direction, and when the wringing plate 151 moves toward the front side, the extension portion 152 interferes with the brush on the brushing shaft. However, since the brush is a flexible member, the rotation of the brushing shaft is not directly stopped, and the extension portion 152 generates resistance to the brushing shaft, thereby reducing the rotation speed of the brushing shaft. Also, by moving the wringing plate 151, the contact area between the extension 152 and the brush is increased or decreased, and thus the rotation speed of the brush shaft is adjusted.

In addition, the brush is not limited to be arranged on the brushing shaft, and other flexible parts such as sponge or cotton cloth can be arranged on the brushing shaft as long as the purpose of cleaning the cleaning block can be achieved.

According to the cleaning device 1 of the application, the setting can be close to or keep away from the wringing plate of annular conveying component 11, and set up extension 152 at the lower extreme of wringing plate 151, through the distance between control wringing plate 151 and the annular conveying component 11, with the resistance of adjusting extension 152 to scrubbing 142, and then adjust the slew velocity of scrubbing 142, the user can adjust the rotational speed of scrubbing 142 as required, make scrubbing 142 can scrub the cleaning better, the cleaning effect of cleaning device 1 has been improved.

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

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

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 present application comprises at least one endless conveying member 11 and at least one cleaning block 12, the endless conveying member 11 being operable at the same speed in the circumferential direction of the endless conveying member 11. The cleaning block 12 is mounted on the annular conveying member 11 and moved by the annular conveying member 11 in the circumferential direction of the annular 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 drive roller and a driven roller, on which an integral type cloth cover is wound in a ring shape, and the width of the integral type cloth cover is substantially identical to the axial length of the drive roller and the driven roller. However, because the contact force between the integrated cloth cover and the roller is not consistent, the force applied by the roller to the cloth is not uniform, so that the integrated cloth cover is easy to deform and not easy to replace for cleaning. Under the condition that the rag sleeve is distorted, the rag sleeve is stressed unevenly at each position when contacting with the ground, so that the rag sleeve is easy to deform, and the rag sleeve is asynchronous with the driving roller and the driven roller, so that the rag sleeve is damaged.

According to the cleaning device 1 of the present application, by installing the cleaning block 12 on the endless conveying member 11, wherein the cleaning block 12 can clean a surface to be cleaned such as a floor, and the cleaning block 12 facilitates replacement cleaning. And the cleaning block 12 and the annular conveying component 11 can realize synchronous movement, and the cleaning effect is better. And the cleaning block 11 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 the 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 conveying member, and rotation of the endless conveying member 11 causes one or more cleaning blocks 12 mounted thereon to move synchronously.

In one embodiment of the present invention, the number of the endless conveying members 11 is two or more, as shown in fig. 1. The utility model discloses in, do not limit to the quantity of annular conveying part 11, can set up arbitrary quantity in two or more quantity according to the demand. Two or more endless conveying members 11 are moved synchronously at the same speed, a part of one cleaning block 12 is mounted on one endless conveying member 11, and another 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 is not twisted. The synchronous movement between two or more endless conveying members 11 will be achieved by the connection of a timing belt or chain with a driving pulley and a driven pulley as described below, which will be described in detail below.

In summary, the at least one endless conveying member 11 as a whole performs a movement 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 transport element 11.

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

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, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

A plurality of cleaning blocks 12 are mounted on an annular conveying component 11, the cleaning blocks 12 are arranged at intervals along the circumferential direction of the annular conveying component 11, and the cleaning blocks 12 are not connected with each other. When the cleaning device 1 works, a single cleaning block 12 cleans the ground, the contact area between the cleaning block 12 and the ground is small, and the friction force is small. Each independent cleaning block 12 can more stably clean the ground, 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 application, by arranging the plurality of cleaning blocks 12 at intervals along the circumferential direction of the annular conveying component 11, when the cleaning device 1 works, each cleaning block 12 cleans the ground independently, and each cleaning block is convenient to replace and clean independently. Each cleaning block 12 is evenly stressed at each position when in contact with the ground, the cleaning blocks 12 can be effectively prevented from deforming, 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 annular conveying component 11, and the cleaning effect is better.

The plurality of cleaning blocks 12 are arranged at intervals along the circumferential direction of the annular conveying component 11, so that the gap between two adjacent cleaning blocks 12 is increased, and dirt such as dust is prevented from being accumulated in the gap between two adjacent cleaning blocks 12. In addition, the two adjacent cleaning blocks 12 are arranged at intervals, so that the two adjacent cleaning blocks 12 can be prevented from generating acting force, the cleaning blocks 12 can be better kept synchronous with the movement of the annular conveying component 11, the service life of the cleaning blocks 12 is further prolonged, and the 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 blocks 12 is 20 mm to 800 mm. When the distance between two adjacent cleaning blocks 12 is set to 20 mm, the cleaning blocks 12 can be ensured to have a sufficiently high density in the circumferential direction of the annular conveying member 11, the cleaning frequency of the cleaning device 1 on the floor surface is increased, and the cleaning effect is improved. 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. Meanwhile, the cleaning effect of the cleaning device on the floor can be maintained by increasing the rotating speed of the annular conveying part 11. It is to be understood 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 subject to actual requirements.

According to an embodiment of the present application, the cleaning device 1 further includes a driving wheel 110 and a driven wheel 120, the driven wheel 120 and the driving wheel 110 are arranged at a distance from each other in the longitudinal direction, and a central connecting line between the driven wheel 120 and the driving wheel 110 extends from the center of the driven wheel 110 obliquely upward relative to the horizontal direction.

The endless conveying member 11 is wound around the driving pulley 110 and the driven pulley 120, and the cleaning blocks 12 have a lateral extension greater 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 length of the driving wheel 110 and the driven wheel 120 is relatively short, the length of the cleaning block 12 in the transverse 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 transverse direction is also much longer than the transverse extension length of the endless conveying member 11 (the length of the endless conveying member 11 in the transverse direction).

In the present embodiment, the driving pulley 110, the driven pulley 120 and the endless conveying members 11 constitute a transmission mechanism that stably and reliably moves one endless conveying member 11 at a certain speed or moves a plurality of endless conveying members 11 at the same speed, thereby ensuring that the endless conveying members 11 move integrally in synchronization and stably. The driving pulley 110 is located at the rear side of the driven pulley 120 in the longitudinal direction, at the upper side in the vertical direction, and the cleaning blocks 12 are mounted on the endless conveying members 11 only by a small portion (for example, in the case of including two endless conveying members 11, it is preferable that the cleaning blocks 12 are mounted on the two endless conveying members 11 by the first and second ends thereof), so that the cleaning blocks 12 are in contact with the driving mechanism by a small portion and are not in contact with the driving roller over a large area as in the prior art. Thus, as long as it is ensured that the portions of the cleaning block 12 connected to the endless conveying member 11 move at the same speed, the force applied by the endless conveying member 11 to these connected portions of the cleaning block 12 is uniform. Therefore, all parts of the cleaning block 12 can move synchronously, are not easy to twist, have long service life and have better cleaning effect. However, in the prior art, the driving roller applies force to each part in the transverse direction of the cleaning belt, so that the transverse parts of the cleaning belt are stressed unevenly, and the cleaning belt is twisted. According to the cleaning apparatus 1 of the present application, in the case of including one endless conveying member 11, the cleaning block 12 is moved in synchronization with the endless conveying 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, respective portions of one cleaning block 12 mounted thereon are also moved in synchronization. Therefore, in both cases, the cleaning block 12 is not twisted, and the cleaning effect is better.

The central line between the driving wheel 110 and the driven wheel 120 is inclined relative 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 path of the endless conveying member 11 has a certain inclination angle with the ground. The driven wheel 120 is located at a position corresponding to a lower turn of the track, and the driving wheel 110 is located at a position corresponding to an upper turn of the track. The cleaning block 12 contacts the floor surface when moving to the lower turn of the trajectory to clean the floor surface.

Here, it should be noted that the direction from the driven wheel 120 to the driving wheel 110 is defined as a front-to-rear direction, wherein the front-to-rear direction is the above-mentioned longitudinal direction. Since the cleaning block 12 is in contact with the floor surface to clean the floor surface when it is moved to the position where the driven wheel 120 is located, the position where the cleaning block 12 is in contact with the floor surface is forward and the rest is rearward.

According to one embodiment of the present application, as shown in fig. 1-6, the drive pulley 110 includes a first drive pulley 113 and a second drive pulley 114, the first drive pulley 113 and the second drive pulley 114 being laterally spaced apart. 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 a spacing in the lateral direction. The first driven pulley 115 is longitudinally spaced from the first drive pulley 113, and the second driven pulley 116 is longitudinally spaced from the second drive pulley 114.

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

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

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

The shape of the first annular conveying element 111 and the second annular conveying element 112 may be the same, and the conveying track of the first annular conveying element 111 is consistent with the conveying track of the second annular conveying element 112. After connecting the first and second ends of the cleaning block 12 to the first and second endless conveying
