Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a cleaning roller, a floor scrubber and a cleaning robot. Background Art

[0002] With the development of science and technology and economy, traditional cleaning methods can no longer meet people's current needs. Cleaning equipment has emerged, such as vacuum cleaners, which are lightweight, wireless, and low-noise. In order to meet the needs of floor cleaning in different scenarios, existing cleaning equipment has gradually evolved from the original dry suction to the current cleaning equipment that can add water to clean the floor. A core component of current cleaning equipment with water washing function is the roller brush component or the drum component.

[0003] In order to balance water absorption and floor cleaning, the conventional cleaning roller brush adopts a water-absorbing fluff bundle structure as the cleaning brush layer. This type of cleaning brush has at least the following problems:

[0004] First of all, one end of the bristle bundle is fixed on the supporting rod of the roller brush, and the other end is suspended as a free end. The fluffy and dense bristle bundles constitute the surface cleaning layer of the cleaning roller brush, but each bristle bundle has its own free end. In order to make the bristle bundles more fluffy, the free ends of the bristle bundles are not well bonded together to form a complete surface, but the free ends of the bristle bundles are scattered, resulting in the inability to connect the surfaces of the bristle bundles or the fluff bundles to form a continuous and complete surface. Such a design will inevitably leave large gaps between the bristle bundles. These gaps have a fatal defect of garbage jamming, and as the roller brush works, the garbage jammed in the bristle bundles will get deeper and deeper, which is not conducive to the cleaning of the bristle bundles. Secondly, one end of the bristle bundle is suspended. After the bristle brush absorbs water, during the rotation of the roller brush, the centrifugal force of the water droplets on the bristle bundle is very small because the bristle bundles are fluffy and scattered. As a result, the water droplets on the free end of the bristle bundle are easily thrown onto the ground. This will cause a lot of water stains to remain on the ground after cleaning. It takes a long time for the ground to dry, which is not conducive to cleaning and quick drying of the ground. Therefore, the roller brushes in the prior art still have many problems to be improved. Utility Model Content

[0005] Based on this, it is necessary to provide a surface cleaning roller, a surface cleaning device and an automatic cleaning device to solve the problems in the prior art that a lot of water stains remain on the ground after the roller brush assembly cleans the ground, and garbage is easily stuck on the surface of the roller brush assembly.

[0006] The utility model provides:

[0007] A cleaning roller comprises a roller supporting portion and a cleaning layer, wherein the roller supporting portion and the cleaning layer both extend in the length direction of the cleaning roller, and the cleaning layer at least wraps a portion of the surface of the roller supporting portion; the cleaning layer forms the outer surface of the cleaning roller, and the cleaning layer is used to contact a floor to be cleaned to clean the floor to be cleaned, and the cleaning layer is a foaming material, and the foaming material is a water-absorbing sponge, and the outer surface of the water-absorbing sponge is a continuous surface structure of a mesh or honeycomb structure; the cleaning layer is formed by winding the water-absorbing sponge at least once in a spiral winding manner along the outer surface of the roller supporting portion, and a spiral winding texture in a spiral shape is presented on the outer surface of the cleaning layer.

[0008] In one embodiment, the water-absorbing sponge contains PU material.

[0009] In one embodiment, the cleaning layer is formed by one or more independent water-absorbing sponges being wound one or more times in a spiral manner along the outer surface of the roller support portion.

[0010] In one embodiment, the cleaning layer has a connecting portion, and the connecting portion includes a first connecting portion inclined surface and a second connecting portion inclined surface. After the first connecting surface and the second connecting surface are connected, the spiral winding texture is presented on the cleaning layer.

[0011] In one embodiment, the cleaning roller further includes a handle, which is disposed on one side of the cleaning roller and is used for installing or removing the cleaning roller.

[0012] The utility model also provides a floor scrubber, which comprises the cleaning roller in the utility model.

[0013] The utility model also provides a cleaning robot, which comprises the cleaning roller in the utility model.

[0014] In the embodiment of the present utility model, the cleaning roller of the embodiment has a continuous surface with a mesh or honeycomb structure, and the continuous surface avoids leaving a large number of gaps in the surface of the cleaning roller to hide garbage. This can effectively solve the problem of garbage hiding inside the surface of the cleaning roller, thereby solving the problem of incomplete cleaning and residual garbage inside the cleaning parts. Furthermore, since the surface of the cleaning roller is made of a continuous surface water-absorbing material with a mesh or honeycomb structure, the water-absorbing material is a complete whole, and the water adsorbed on the water-absorbing material is no longer just scattered small water droplets but a complete mass of water. In this way, during the rotation of the cleaning roller, the water adsorbed in the cleaning layer of the cleaning roller is not easily thrown onto the ground due to the centrifugal force, which reduces the residual water on the ground, facilitates the quick drying of the ground, and improves the cleaning efficiency of the ground.

[0029] like Figure 1-Figure 4As shown, some embodiments of the present utility model provide a cleaning roller 100. The overall shape of the cleaning roller 100 is cylindrical or truncated cone. Looking from the inside to the outside along the radial direction of the cleaning roller 100 (as shown in the figure, the length direction x of the cleaning roller is defined, and the radial direction is y), at least a roller support portion 110 and a cleaning layer 120 are included. The roller support portion 110 and the cleaning layer 120 are extended along the length direction of the cleaning roller 100. The cleaning layer 120 wraps the roller support portion 110 along its circumference. It can be understood that the cleaning layer 120 is wrapped around the outer periphery of the roller support portion 110, or the cleaning layer 120 wraps the other surfaces of the roller support portion 110 except the two end faces. The cleaning layer 120 forms the outer surface of the cleaning roller 100, and the cleaning layer 120 contacts the ground to be cleaned to clean the ground to be cleaned. There are requirements for the selection of materials for the cleaning layer 120. The cleaning layer 120 needs to be made of a foaming material, and the foaming material can be a water-absorbing sponge. It should be noted that although the sponge is a foaming material, only a water-absorbing sponge can be used as the cleaning layer 120 here, which requires the open porosity of the foaming material to be high enough. The preferred method is to control the open porosity of the foaming material to be above 60%. The selected water-absorbing sponge also has strict requirements on its outer surface. The outer surface of the water-absorbing sponge here needs to be a continuous surface structure of a mesh or honeycomb structure. If the surface has obvious large pits and an uneven surface, the water-absorbing sponge cannot be used as the cleaning layer 120 here to contact the ground to be cleaned, unless the surface of the water-absorbing sponge is treated for flatness. The cleaning layer 120 can be formed by winding the water-absorbing sponge along the outer surface of the roller support part 110 in a spiral winding manner for at least one circle. The outer surface of the cleaning layer 120 presents a spiral winding texture in a spiral shape. It should be noted that a single piece (a piece, a strip) of water-absorbing sponge can be used to wrap one or several circles along the outer surface of the roller support part 110 to form a surface continuous cleaning layer 120. At the same time, several (two or more) absorbent sponges can be used to wrap one or several circles along the outer surface of the roller support part 110 to form a surface continuous cleaning layer 120. The surface continuous cleaning layer 120 needs to satisfy the requirement that the surface of the cleaning layer is continuous and there should be no obvious gaps to hide garbage. Although a roller brush made of multiple bundles of mutually separated hair or fluff with large gaps on the surface is absorbent, there are many large gaps on the surface of the material itself. Therefore, the absorbent surface formed by these hair bundles or fluff is intermittent and discontinuous, which is different from the absorbent material with a continuous surface required by this scheme. The surface of the absorbent sponge has a mesh or honeycomb shape structure, and the absorbent sponge is made of absorbent material with a continuous surface (the surface of the absorbent material needs to be relatively flat).

[0030] Since the surface of the absorbent sponge is a continuous surface structure in a mesh or honeycomb structure, the continuous surface absorbent material absorbent sponge is used to make the cleaning layer 120, so that a large number of obvious gaps on the surface of the cleaning roller 100 to hide garbage and dirt can be avoided, which can effectively solve the problem of garbage and dirt hiding on the surface of the cleaning roller 100, thereby solving the problem of incomplete cleaning and residual garbage inside the cleaning component. Compared with the existing roller brush bristles, which have a large number of obvious gaps and can hide a lot of garbage during the cleaning process, the cleaning roller 100 of this solution solves the problem of garbage hiding inside the surface of the cleaning component. Furthermore, since the surface of the cleaning roller 100 is made of a continuous surface water-absorbing sponge with a mesh or honeycomb structure, the surface of the water-absorbing sponge is continuous and has been used as a complete and large-area whole. The water absorbed on such a large-area whole water-absorbing sponge is a complete mass of water connected together, rather than scattered small water droplets. In this way, during the rotation of the cleaning roller 100, the water absorbed in the cleaning layer 120 of the cleaning roller 100 is no longer easily thrown onto the ground due to the centrifugal force, which effectively reduces the residual water on the ground and reduces the quick-drying time of the ground. Compared with the prior art, which uses multiple fluff bundles or multiple bristle bundles to form a cleaning roller brush, each bristle bundle is scattered, and the small water droplets on each bristle bundle are easily thrown onto the ground by the centrifugal force when the roller brush rotates, causing a lot of residual water on the ground. The water-locking performance of the cleaning roller 100 of this solution is better, and the water absorbed on the cleaning layer 120 of the cleaning roller 100 will not be easily thrown onto the ground due to the rotation of the surface cleaning roller 100, which effectively solves the problem of excessive residual water on the ground.

[0031] In order to make the water absorption performance of the water-absorbing sponge better, the water-absorbing sponge can be made of a whole piece of PU material, or can be made of a water-absorbing material containing PU material.

[0032] In order to facilitate the formation of the cleaning layer 120 by winding the water-absorbing sponge, the cleaning layer 120 may be designed to have a connecting portion 1200 thereon, the connecting portion 1200 comprising a first connecting inclined surface 1201 and a second connecting inclined surface 1202. After the first connecting inclined surface 1201 and the second connecting inclined surface 1202 are butt-jointed and bonded together, a spiral winding texture in a spiral shape is left on the cleaning layer 120. In order to facilitate the connection of the connecting portion 1200, the first connecting inclined surface 1201 and the second connecting inclined surface 1202 may be made into completely butt-jointed inclined surfaces, and are butt-jointed and bonded together through bevel matching.

[0033] The design of spirally winding a water-absorbing sponge around the outer surface of the roller support part 110 to form a cleaning layer 120 and leaving a spiral winding texture on the cleaning layer has very important technical significance compared to other cleaning layer designs, which is mainly reflected in: when the cleaning roller 100 is installed on the cleaning equipment for operation, a scraper bar needs to be installed on the cleaning equipment, and the function of the scraper bar is to scrape off the residual garbage and sewage on the surface of the cleaning roller 100 (the function of the scraper bar greatly improves the cleaning efficiency of the cleaning system, and general cleaning equipment needs to be designed with a scraper bar to scrape the surface of the roller brush or roller). The cleaning layer 120 is made into a spirally wound texture to ensure that the scraping area of ​​the scraper strip on the connection part of the cleaning layer is the same per unit time, so that during the rotation of the cleaning roller 100, the contact surface of the scraper strip of the cleaning device on the connection part of the cleaning layer of the cleaning roller 100 is more uniform, so that the force of the scraper strip of the cleaning device on the connection part of the cleaning roller 100 is more uniform, and at the same time, the contact area between the connection part of the cleaning layer and the ground per unit time is the same, so that the pressure of the cleaning roller 100 on the ground is more uniform, so that the cleaning roller can run more smoothly on the ground and ensure the stable cleaning performance of the cleaning roller 100. In addition, the winding texture of the cleaning layer of the cleaning roller 100 is designed to be spiral, and during the forward and reverse rotation of the cleaning roller 100, the scraper strip installed in the cleaning device will not damage the connection part of the cleaning roller 100 and cause damage to the surface of the cleaning roller 100, effectively avoiding the problem of the connection part of the cleaning layer being scratched by the scraper strip, and improving the service life of the cleaning roller.

[0034] Further, in order to facilitate the installation of the cleaning roller 100 on the cleaning device, or to facilitate the removal of the cleaning roller 100 from the cleaning device, a handle 130 can be provided at one end of the cleaning roller 100. The user can hold the handle 130 to realize the removal of the cleaning roller 100.

[0035] like Figure 5 As shown,

[0036] The present invention also provides a floor scrubber 200. It should be noted that the floor scrubber 200 may be a floor scrubber with a negative pressure suction motor or a floor scrubber without a negative pressure suction motor. The floor scrubber 200 is equipped with a cleaning roller 100 provided by the present invention. The floor scrubber provided by the present invention provides a very good and practical technical solution in solving the problem of residual garbage in the cleaning parts, the problem of excessive residual water on the ground after cleaning, and the problem of quick drying of the ground after the floor scrubber is working.

[0037] like Figure 6 As shown,

[0038] The utility model also provides a cleaning robot 300, on which the cleaning roller 100 provided by the utility model is installed. The cleaning robot provided by the utility model provides a very good and practical technical solution in solving the problem of residual garbage in the cleaning parts, solving the problem of excessive residual water on the ground after cleaning, and solving the problem of quick drying of the ground after the floor scrubber is working.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
