Existing cleaning devices typically provide a scraper bar at the bottom of their cleaning elements for scraping away residual dirty water as the cleaning elements clean the floor.

However, the conventional scraping strip has poor scraping effect, so that sewage is easy to remain, and the cleaning effect is affected. This is because the shape of the cleaning component and the shape of the scraping strip of the existing cleaning device are not adapted, for example, the side of the cleaning component close to the surface to be cleaned is generally a round angle and has a certain radian, while the existing scraping strip is perpendicular to the surface to be cleaned, and a large gap area exists between the scraping strip and the cleaning component when the scraping strip is abutted to the surface to be cleaned, so that the sewage is easy to remain in the gap area and even leak from one side of the gap area, and the cleaning effect is affected.

Therefore, the embodiment of the utility model provides a cleaning device, wherein the first scraping part of the first scraping strip is matched with the turning part of the first annular belt, so that the residue of sewage can be reduced when the surface to be cleaned is scraped, and the cleaning effect is improved.

Referring to fig. 1-3, an embodiment of the present utility model provides a cleaning apparatus 100, which includes a cleaning belt member 10 and a wiper strip assembly 20, wherein the cleaning belt member 10 includes a first endless belt 11 for cleaning a surface to be cleaned, and the first endless belt 11 has a turning portion 111 adjacent to the surface to be cleaned. The wiper strip assembly 20 is provided behind the cleaning belt member 10 in the advancing direction of the cleaning device 100 for wiping liquid on a surface to be cleaned behind the cleaning belt member 10, the wiper strip assembly 20 comprising a first wiper strip 21 adjacent to the first endless belt 11. Wherein the first wiper 21 includes a first wiper 211 for wiping the surface to be cleaned, the first wiper 211 being configured to fit the turning portion 111.

In the cleaning device 100 according to the embodiment of the present utility model, the first wiping portion 211 of the first scraping strip 21 is configured to be matched with the turning portion 111 of the first annular belt 11, so that the first wiping portion 211 can be close to the turning portion 111, a larger gap area between the first wiping portion 211 and the turning portion 111 is avoided, and when the surface to be cleaned is scraped, the residual sewage can be reduced, and the cleaning effect is improved.

In a specific application, the direction of advance of the cleaning device 100, i.e. the main direction of travel of the cleaning device 100 when in operation. When the cleaning device 100 is operated, the cleaning device moves forward along the surface to be cleaned, so as to clean the surface to be cleaned through the first annular belt 11, and at this time, the first scraping portion 211 can scrape sewage on the surface to be cleaned along with the first annular belt 11, so that the cleaning effect is improved.

In some use scenarios, the surface to be cleaned may be a floor, i.e. the cleaning device 100 is used for cleaning floors. Of course, in other usage scenarios, the surface to be cleaned may also be a wall surface or a window or a ceiling or other surface to be cleaned.

In some embodiments, as shown in fig. 2 and 3, the first wiper 211 may abut the turn 111 of the endless belt. With this arrangement, the first wiping part 211 can be made to closely contact the first endless belt 11 to wipe the surface to be cleaned, so that a gap area is not generated between the first wiping part 211 and the first endless belt 11, residual sewage is avoided, and the cleaning effect can be improved better. For example, the first wiper portion 211 may contact only the distal end of the turning portion 111 (as shown in fig. 2 and 3), may contact the turning portion 111 in a partial region near the distal end, or may contact the turning portion 111 throughout the first wiper portion 211.

Of course, in other embodiments, the first wiper 211 may have a slight gap with the turn 111 of the endless belt. At this time, the first wiping part 211 is structurally matched with the turning part 111, so that a larger gap area is not generated when the first wiping part is close to the turning part 111, residual sewage can be reduced, and the cleaning effect is improved.

Alternatively, the turning portion 111 may be arc-shaped, such as arc-shaped, or may be other shapes.

Illustratively, the turning portion 111 may be curved as a whole, or may be a combination of planar portions and curved portions, where the curved portion of the turning portion 111 is close to the surface to be cleaned, and the first wiper 211 may be configured to fit the entire turning portion 111, or may be configured to fit the curved portion of the turning portion 111. The first wiping part 211 is configured to be matched with the turning part 111, which means that the shape of the first wiping part 211 can be matched with the turning part 111, for example, the first wiping part 211 has arc-shaped parts, and the radians of the first wiping part 211 and the turning part can be the same, and can also have slight differences, so that the first wiping part 211 can be close to the turning part 111 at least at the tail end of the surface to be cleaned, thereby avoiding generating larger gap areas, reducing sewage residues and improving cleaning effect.

In some embodiments, as shown in fig. 2-5, the turning portion 111 is arc-shaped, the first wiper 21 further includes a first fixing portion 212, the first wiper 211 includes a first side 2111 and a second side 2112 opposite to the first side 2111, the first side 2111 of the first wiper 211 is connected to the first fixing portion 212, the second side 2112 of the first wiper 211 is for wiping the surface to be cleaned, and the first side 2111 to the second side 2112 of the first wiper 211 are arc-shaped to extend toward the first endless belt 11. In this embodiment, the first fixing portion 212 may be disposed to facilitate the first wiper 21 to be mounted at a preset position, and the first wiper 211 may be disposed to bend and extend toward the first annular belt 11 in an arc shape, so as to adapt to the arc-shaped turning portion 111, so as to reduce the residual sewage and improve the cleaning effect when the first wiper 211 wipes the surface to be cleaned.

In some embodiments, as shown in fig. 3, the first wiper 21 further includes a protrusion 213, where the protrusion 213 is disposed on a side of the first wiper 211 opposite the first endless belt 11 and between the first side 2111 and the second side 2112, and the second side 2112 of the first wiper 211 wipes the liquid on the surface to be cleaned when the cleaning device 100 moves forward, and the protrusion 213 is used to abut against the surface to be cleaned to lift the second side 2112 of the first wiper 211 when the cleaning device 100 moves backward. In the present embodiment, by the provision of the protrusions 213, the second side 2112 of the first wiper 211 can be lifted up when the cleaning device 100 moves backward, so that the second side 2112 of the first wiper 211 abutting against the surface to be cleaned can be separated from the surface to be cleaned when the cleaning device 100 is retracted, thereby realizing cleaning of the bottom space.

In some embodiments, the protrusions 213 may be integrally formed with the first wiper 211, thereby reducing assembly processes, reducing production costs, and improving structural stability.

In some embodiments, the first fixing portion 212 and the first wiping portion 211 are integrally formed, so that the assembly process is reduced, the production cost is reduced, and the structural stability is improved.

Illustratively, the surface to be cleaned may be a horizontal surface such as the floor, in which case the height direction of the cleaning apparatus 100 is a vertical direction perpendicular to the horizontal surface.

In some embodiments, the first securing portion 212 extends in a height direction of the cleaning device 100. In this embodiment, since the first wiping portion 211 needs to be close to the surface to be cleaned and needs to be located at a lower position relative to the entire cleaning apparatus 100, the first fixing portion 212 extends along the height direction of the cleaning apparatus 100, so that the first fixing portion is convenient to be mounted to a predetermined position. In addition, the first fixing portion 212 extends vertically, and a fixing structure such as a fixing screw is also convenient to fix the first fixing portion 212 to a predetermined position in a horizontal direction.

In some embodiments, the first wiper 211 is made of a flexible material. In this embodiment, the flexible material may be a soft rubber material such as silica gel, rubber, and the like, and when abutting against the surface to be cleaned, the flexible material may also provide elastic force to act on the surface to be cleaned, so as to maintain the abutting, and promote the wiping effect of the sewage. Of course, the flexible material may be other materials that can flexibly wipe the surface to be cleaned.

In some embodiments, as shown in fig. 1-7, the cleaning apparatus 100 further includes a main frame 30, and the cleaning belt member 10 and the wiper strip assembly 20 are mounted to the main frame 30.

In the present embodiment, the base 22 and the first mounting surface 221 are provided to support the first wiper strip 21, thereby preventing the first wiper strip 21 from bending backward when wiping the surface to be cleaned.

In some embodiments, as shown in fig. 5 and 7, the first mounting surface 221 includes a planar portion 2211 and an arcuate portion 2212, the planar portion 2211 abutting the first fixed portion 212, the arcuate portion 2212 abutting at least a portion of the first wiper 211. In the present embodiment, the first fixing portion 212 can be supported by the planar portion 2211, and the first wiping portion 211 can be supported by the arc portion 2212, so that the radian of the first wiping portion 211 can be maintained, the first wiping portion 211 can be always adapted to and close to the turning portion 111, the first wiping portion 211 is prevented from bending backward when the surface to be cleaned is scraped, and the cleaning effect is improved.

For example, as shown in fig. 4, 5 and 7, the arc-shaped portion 2212 may abut against a portion of the first wiping portion 211 near the first side 2111, and a portion of the first wiping portion 211 near the second side 2112 may be suspended, so as to facilitate wiping and cleaning the surface to be cleaned.

In some embodiments, as shown in fig. 4-6, the wiper strip assembly 20 further includes a first positioning plate 23, the first positioning plate 23 being disposed in front of the first wiper strip 21 in the forward direction of the cleaning apparatus 100 and securing the first securing portion 212 to the first mounting surface 221.

In some embodiments, as shown in fig. 4-6, the first positioning plate 23 has a slope structure 231 that slopes downward toward the direction of the first endless belt 11, and a portion of the first wiper 211 near the first side 2111 is sandwiched between the first mounting surface 221 and the slope structure 231. In this embodiment, by the arrangement of the inclined surface structure 231, the radian of the first wiper portion 211 can be maintained in cooperation with the first mounting surface 221, so that the first wiper strip 21 is prevented from being deformed by force, so that the first wiper portion 211 can always keep fit and approach the turning portion 111, and the cleaning effect is improved. Wherein, since the first positioning plate 23 is generally a plate-shaped structure formed by processing hard materials, the inclined surface structure 231 is convenient to process.

Of course, in other embodiments, the bevel structure 231 may be replaced by a cambered surface structure, and the radian of the first wiper 211 can also be maintained in cooperation with the first mounting surface 221.

In some embodiments, as shown in fig. 2, 4-6, the wiper assembly 20 may further include a second wiper 24, the second wiper 24 being disposed behind the first wiper 21 in the forward direction of the cleaning device 100, the second wiper 24 having a second wiper portion 241 for wiping the surface to be cleaned. Wherein the second wiping part 241 is configured to be elastically deformable in the case of wiping the surface to be cleaned so that the tip of the second wiping part 241 is held against the surface to be cleaned, the tip of the second wiping part 241 is bent backward when the cleaning device 100 moves forward, and the tip of the second wiping part 241 is bent forward when the cleaning device 100 moves backward.

In addition, the second fixing portion 242 extends vertically, and a fixing structure such as a fixing screw is also convenient to fix the second fixing portion 242 to a predetermined position in a horizontal direction.

In some embodiments, the second wiper 241 is made of a flexible material. In this embodiment, the flexible material may be a soft rubber material such as silica gel, rubber, and the like, and when abutting against the surface to be cleaned, the flexible material may also provide elastic force to act on the surface to be cleaned, so as to maintain the abutting, and promote the wiping effect of the sewage. Of course, the flexible material may be other materials that can flexibly wipe the surface to be cleaned.

In some embodiments, as shown in fig. 1-7, the cleaning apparatus 100 further includes a main frame 30, and the cleaning belt member 10 and the wiper strip assembly 20 are mounted to the main frame 30.

I.e. the gap from the bottom of the lead-in member 40 to the surface to be cleaned can be automatically adjusted.

As an embodiment, when the cleaning device 100 performs the cleaning operation on the surface to be cleaned, the gap between the guide member 40 and the surface to be cleaned can be automatically adjusted according to the size of the garbage, i.e., the gap between the bottom of the guide member 40 and the surface to be cleaned can be automatically adjusted according to the size of the garbage. In a specific application, when the cleaning device 100 moves on a surface to be cleaned to perform cleaning work, if a large volume of garbage is encountered, the bottom of the guiding member 40 can be lifted up, so that the large volume of garbage can be guided to the cleaning belt member 10 or the working area of the cleaning belt member 10 through the guiding member 40, thereby realizing the effect that the guiding member 40 can automatically adjust the gap between the guiding member 40 and the surface to be cleaned according to the size of the garbage, and enabling the cleaning device 100 to remove the garbage with different volumes.

As an embodiment, when the cleaning device 100 performs the cleaning work on the surface to be cleaned, the gap between the leading-in member 40 and the cleaning belt member 10, that is, the gap between the rear side portion of the leading-in member 40 and the front side portion of the cleaning belt member 10 can be automatically adjusted.

As an embodiment, when the cleaning device 100 performs the cleaning work on the surface to be cleaned, the introducing member 40 can automatically adjust the gap with the first endless belt 11 according to the size of the garbage. By adopting the arrangement scheme, garbage with different volume sizes can be conveyed between the guide-in member 40 and the first annular belt 11, and adverse phenomena that the garbage is clamped between the guide-in member 40 and the first annular belt 11 in the conveying process are effectively prevented.

As an embodiment, as shown in fig. 9, the introducing member 40 has an introducing portion 41 adjacent to the surface to be cleaned and having an adjustable gap with the surface to be cleaned, and the introducing portion 41 is used for introducing the garbage on the surface to be cleaned to the first endless belt 11 or the working area of the first endless belt 11. The introduction portion 41 is a bottom portion of the introduction member 40, that is, a portion of the introduction member 40 closest to the surface to be cleaned in the height direction of the cleaning device 100. According to the technical scheme, the gap between the guide-in part 41 and the surface to be cleaned is set to be adjustable, that is to say, the gap can be increased or reduced, so that the gap can be suitable for garbage with different volumes and sizes, in this way, the guide-in member 40 can guide small-volume garbage to the first annular belt 11 or the working area of the first annular belt 11, and can guide large-volume garbage to the first annular belt 11 or the working area of the first annular belt 11, thereby effectively ensuring the cleaning effect of the cleaning device 100 for cleaning the garbage on the surface to be cleaned.

As one embodiment, the introducing member 40 is rotatably coupled to the cleaning belt member 10. When the introducing member 40 rotates relative to the cleaning belt member 10, the gap between the introducing member 40 and the surface to be cleaned can be adjusted, and the gap between the introducing member and the cleaning belt member 10 can be adjusted, so that the effect that the introducing member 40 can automatically adjust the gap between the introducing member and the surface to be cleaned and the gap between the introducing member and the first annular belt 11 according to the size of the garbage can be realized, and the cleaning device 100 can remove garbage with different sizes and volumes. Of course, in particular applications, the rotatable connection of the introduction member 40 is not limited thereto, for example, as alternative embodiments, the introduction member 40 may be rotatably connected to the recovery vessel 50.

In some embodiments, as shown in fig. 8 and 9, the introduction member 40 may be an annular band member. The introduction member 40 comprises a second endless belt 42, a second roller 43 and at least one second guide element 44, the second endless belt 42 being looped around the second roller 43 and the second guide element 44. The second roller 43 is used to rotate under the driving of the external force to drive the second endless belt 42 to rotate, and the second endless belt 42 can form a tensioned endless structure through the tensioning and guiding of the second roller 43 and the second guiding member 44. Of course, the introduction member 40 may be a plate-like member or a combination of an annular belt member and a plate-like member as an alternative embodiment.

As an embodiment, as shown in fig. 8, the cleaning device 100 further includes a second motor 45 for driving the second roller 43 to rotate, and the second motor 45 is in driving connection with the second roller 43 for driving the second roller 43 to rotate so as to drive the second endless belt 42 to rotate. By driving the second motor 45, the capacity of the introduction member 40 to introduce the refuse can be advantageously increased. In a specific application, the cleaning device 100 further includes a second transmission member 46, where the second transmission member 46 is drivingly connected between the second motor 45 and the second roller 43, and the second motor 45 drives the second roller 43 to rotate through the second transmission member 46. The disposing function of the second transmission member 46 may include at least one of the following functions: the rotation speed output by the second motor 45 is regulated to the rotation speed required by the design of the second roller 43; and the power transmission within a certain distance range is realized. The second transmission member 46 may include at least one of a belt transmission or a rack and pinion transmission or a chain transmission.
