Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning appliances, in particular to a surface cleaning roller, a surface cleaning device and an automatic cleaning device. 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 in the air 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 surfaces of each bristle bundle or each fluff bundle cannot be connected to form a continuous and complete surface. Such a design will inevitably leave 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 brush absorbs water, during the rotation of the roller brush, the bristle bundles are fluffy and scattered, so the centrifugal force of the water droplets on the bristle bundle is very small, causing the water droplets on the free end of the bristle bundle to be easily thrown onto the ground. This will cause a lot of water stains to remain on the ground after cleaning, and it will take a long time for the ground to dry, which is not conducive to cleaning and quick drying of the ground.

[0005] Furthermore, when there is hard or large garbage remaining on the ground, the roller brush will be lifted up when it encounters large garbage because there is no deformation space inside the roller brush during the cleaning process. This is not conducive to the stable operation of the cleaning equipment, and the lifted roller brush will reduce the air performance of the cleaning equipment, thereby reducing the cleaning ability of the cleaning equipment.

[0006] Therefore, the roller brush of the prior art still has many problems to be improved. Utility Model Content

[0015] In one embodiment, the surface water-absorbing layer is formed by winding a water-absorbing material along the outer surface of the lining buffer layer in a spiral winding manner for one or several turns, and the surface water-absorbing layer has an overlapping portion, and the overlapping portion presents one or several spiral overlapping edge contours in the shape of a spiral winding.

[0023] The surface cleaning roller of the above embodiment, due to the setting of the layered structure, is also provided with an inner lining buffer layer in the middle, so that when the surface cleaning roller encounters larger garbage on the ground when cleaning the ground, the surface of the surface cleaning roller can be deformed, so that the surface cleaning roller can be effectively prevented from being lifted by the garbage on the ground and being unfavorable for cleaning. Secondly, since the surface of the surface cleaning roller is a continuous surface with a mesh or honeycomb structure, the continuous surface avoids leaving a large number of gaps on the surface of the surface cleaning roller to hide garbage, so that the garbage can be effectively hidden inside the cleaning surface of the surface cleaning roller, thereby solving the problem of incomplete cleaning and residual garbage inside the cleaning component. Furthermore, since the surface of the surface 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 absorbed on the water-absorbing material is no longer just a few scattered small water droplets, but becomes a complete mass of water, so that during the rotation of the surface cleaning roller, the water absorbed in the water-absorbing layer of the surface cleaning roller is not easily thrown onto the ground due to the centrifugal force, reducing the residual water on the ground and facilitating the quick drying of the ground. And the surface water-absorbing layer can be made very thin, which can further reduce the residual water stains on the ground during the cleaning process and improve the cleaning efficiency of the ground.

[0025] The surface cleaning device of this embodiment is adopted. Due to the layered structure of the surface cleaning drum, an inner lining buffer layer is also arranged in the middle. In this way, when the surface cleaning drum encounters larger garbage on the ground while cleaning the ground, the surface of the surface cleaning drum can be deformed, which can effectively avoid the problem that the surface cleaning drum is lifted by the garbage on the ground and is not conducive to cleaning. Secondly, since the surface of the surface cleaning drum is a continuous surface with a mesh or honeycomb structure, the continuous surface avoids leaving a large number of gaps on the surface of the surface cleaning drum to hide garbage, which can effectively solve the problem that garbage will be hidden inside the cleaning surface of the surface cleaning drum, thereby solving the problem of incomplete cleaning and residual garbage inside the cleaning component. Furthermore, since the surface of the surface cleaning drum 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 absorbed on the water-absorbing material is no longer just a few scattered small water droplets, but becomes a complete mass of water.

[0027] The automatic cleaning device of this embodiment is provided with a lining buffer layer in the middle due to the layered structure. In this way, when the surface cleaning roller encounters larger garbage on the ground while cleaning the ground, the surface of the surface cleaning roller can be deformed, which can effectively avoid the problem that the surface cleaning roller is lifted by the garbage on the ground and is not conducive to cleaning. Secondly, since the surface of the surface cleaning roller is a continuous surface with a mesh or honeycomb structure, the continuous surface avoids leaving a large number of gaps on the surface of the surface cleaning roller to hide garbage, which can effectively solve the problem that garbage will be hidden inside the cleaning surface of the surface cleaning roller, thereby solving the problem of incomplete cleaning and residual garbage inside the cleaning component. Furthermore, since the surface of the surface 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 a few scattered small water droplets, but becomes a complete mass of water.

[0058] Figure 1-Figure 18 It is one or more embodiments of the present invention.

[0059] The surface cleaning roller 10 is in the shape of a cylinder or a barrel. The surface cleaning roller 10 presents a layered structure. When viewed from the inside to the outside along the radial direction of the surface cleaning roller 10, it at least includes a support portion 100, an inner lining buffer layer 200, and a surface water absorption layer 300. The support portion 100 is located at the innermost side of the surface cleaning roller 10. The surface cleaning roller 10 can be made solid or hollow. In one implementation, the surface cleaning roller 10 can be made of plastic or metal. In addition, in other embodiments, the material of the surface cleaning roller 10 can also be made of other materials such as fiber or glass and other solid materials, as long as it can ensure that it has a certain hardness and can play the role of supporting the inner lining buffer layer 200 and the surface water absorption layer 300. The support portion 100, the inner lining buffer layer 200 and the surface water absorption layer 300 all extend along the length direction of the surface cleaning roller 10. The length direction of the surface cleaning roller 10 can refer to the attached Fig.11 The direction x is marked, and the radial direction of the surface cleaning roller 10 can be referred to in the attached Fig.11Direction y is marked. The lining buffer layer 200 is located between the support portion 100 and the surface water-absorbing layer 300. The lining buffer layer 200 wraps the support portion 100 along its circumference. It can be understood that the lining buffer 200 wraps the outer periphery of the support portion 100, or the lining buffer layer 200 wraps other surfaces of the support portion 100 except the two end faces. In other embodiments, there may be other layers between the lining buffer layer 200 and the support portion 100, but it should be emphasized that even if there are other layers between the two, the lining buffer layer 200 also wraps the support portion 100 in its circumferential direction, whether it is direct contact wrapping or non-contact wrapping, it should be within the protection scope of this scheme. The lining buffer layer 200 is made of a deformable and recoverable buffer material. The deformable and recoverable here means that the lining buffer layer 200 can be deformed under a certain local pressure or external force. After deformation, when the local pressure or external force disappears, the lining buffer layer 200 can return to its shape before deformation. The material of the inner lining buffer layer 200 is a deformable and recoverable sponge, soft glue or other flexible and deformable materials that can recover after deformation. It should be noted here that if a sponge is used, it must be a deformable and recoverable sponge. A general sponge without deformation recovery ability cannot be used as the inner lining buffer layer 200 required by this solution. The inner lining buffer layer 200 is used in the surface cleaning roller 10. Its function and main role is to enable the surface cleaning roller 10 to generate a deformable and recoverable buffer space in the radial direction (the buffer space is also the buffer deformation part, which can be deformed appropriately and can recover after deformation) to adapt to floor cleaning in different scenarios. Because the size, thickness, hardness, height, etc. of the garbage left on the ground in different scenes are different, in order to make the surface cleaning roller 10 more applicable to different ground cleaning scenes, it is necessary to make the surface of the surface cleaning roller 10 have a certain deformation recovery buffering ability, especially for the garbage that is relatively hard, relatively large among the general small garbage, and relatively high among the general garbage on the ground, when the surface cleaning roller 10 is rolled over by these garbage, it will not be easily lifted up by these garbage and affect the cleaning efficiency of the surface cleaning roller 10, and when the surface cleaning roller 10 has the deformation recovery buffering ability, the pressure of the ground garbage on the surface cleaning roller 10 will be reduced, which is more conducive to avoiding the surface wear of the surface cleaning roller 10 and can increase the service life of the surface cleaning roller 10. The surface water absorption layer 300 forms the outer surface of the surface cleaning roller 10, and the surface water absorption layer 300 is used to contact with the surface or ground to be cleaned to clean the surface or ground to be cleaned.It should be noted that the surface water-absorbing layer 300 must be made of a water-absorbing material. Non-water-absorbing materials cannot be used as the surface water-absorbing layer 300 required in this solution, because one of the main functions of the surface water-absorbing layer 300 is to absorb the residual water on the surface to be cleaned or on the ground. It should be noted that after the surface water-absorbing layer 300 is made of a water-absorbing material, the surface of the surface water-absorbing layer 300 must also be continuous (the surface of the surface water-absorbing layer 300 is relatively flat). Although a roller brush made of a plurality of mutually separated hair bundles or fluffs with a large gap on the surface is absorbent, there are many large gaps on the surface of the material itself. Therefore, the water-absorbing surface formed by these hair bundles or fluffs is intermittent and discontinuous, which is different from the water-absorbing material with a continuous surface required by this solution. The surface of the surface water-absorbing layer 300 presents a mesh or honeycomb shape structure, and the surface water-absorbing layer 300 is made of a water-absorbing material with a continuous surface (the surface of the water-absorbing material needs to be relatively flat). Since the surface cleaning roller 10 adopts a layered structure and an inner lining buffer layer 200 is arranged in the middle, the surface cleaning roller 10 can be used to clean the ground in different scenes. In this way, when the surface cleaning roller 10 encounters hard, large, or high and large garbage on the ground when cleaning the ground or cleaning the surface to be cleaned, the surface of the surface cleaning roller 10 can be deformed, so that the surface cleaning roller 10 can be effectively prevented from being lifted by the garbage on the ground, which is not conducive to cleaning. Compared with the cleaning roller brush or roller of the prior art, when encountering large garbage on the ground, the cleaning roller brush is lifted by the garbage, resulting in low cleaning efficiency and incomplete cleaning. The problem has been significantly improved. Secondly, since the surface of the surface cleaning roller 10 is a continuous surface structure with a mesh or honeycomb structure, the surface water-absorbing layer 300 is made of a continuous surface water-absorbing material, so that a large number of obvious gaps on the surface of the surface cleaning roller 10 can be avoided to hide garbage, which can effectively solve the problem of hiding garbage on the surface of the surface cleaning roller 10, thereby solving the problem of incomplete cleaning and residual garbage inside the cleaning components. Compared with the existing roller brush bristles, which have a lot of obvious gaps between them and can hide a lot of garbage during the cleaning process, the surface cleaning roller 10 of this solution solves the problem of garbage hiding inside the surface of the cleaning component. Furthermore, since the surface of the surface cleaning roller 10 is made of a continuous surface water-absorbing material with a mesh or honeycomb structure, the surface of the water-absorbing material is continuous and has been used as a complete whole with a large area. The water adsorbed on such a large-area whole water-absorbing material is a complete mass of water connected together, rather than small scattered water droplets. In this way, during the rotation of the surface cleaning roller 10, the water adsorbed in the surface water-absorbing layer 300 of the surface cleaning roller 10 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 a plurality of fluff bundles or a plurality of bristle bundles to form a cleaning roller brush, in which the bristle bundles are dispersed and the small water droplets on the bristle bundles are easily thrown onto the ground by the centrifugal force when the roller brush rotates, resulting in a problem of a lot of residual water on the ground. The surface cleaning roller 10 of the present scheme has better water locking performance, and the water adsorbed on the surface water absorption layer 300 of the surface cleaning roller 10 will not be easily thrown onto the ground due to the rotation of the surface cleaning roller 10, which effectively solves the problem of excessive residual water on the ground.

[0060] like Figure 4 As shown, when the roller brush or roller encounters a large piece of garbage 2 on the ground, the surface cleaning roller 10 with the inner lining buffer layer 200 can deform its surface to prevent the surface cleaning roller 10 from being lifted up by the garbage and leaving the ground. However, when the conventional general roller brush 1 without the inner lining buffer layer 200 encounters a large piece of garbage 2 on the ground, the roller brush 1 will be directly lifted up by the garbage and leave the ground, and the height H from the ground is directly affected by the size and height of the garbage, resulting in reduced cleaning efficiency of the cleaning roller brush 1, incomplete cleaning, and other problems. The reason is that its surface cannot deform to adapt to the garbage to prevent the roller brush 1 from being lifted up.

[0061] Furthermore, in order to further reduce the amount of water adsorbed in the surface cleaning roller 10, a waterproof layer 400 may be provided between the surface water absorption layer 300 and the inner lining buffer layer 200 of the surface cleaning roller 10, and the function of the waterproof layer 400 is to reduce or prevent the water adsorbed in the surface water absorption layer 300 from entering the inner lining buffer layer 200. The waterproof layer 400 may be a waterproof film or glue to achieve water isolation between the surface water absorption layer 300 and the inner lining buffer layer 200.

[0062] Furthermore, the water-absorbing material used in the surface water-absorbing layer 300 can be a foam material. Preferably, the opening porosity of the foam material needs to be greater than 60%. For the foam material with an opening porosity of less than 60%, its water absorption performance is relatively low. The surface water-absorbing layer 300 made of a foam material with an opening porosity of more than 60% has better water absorption performance. Preferably, the foam material is a water-absorbing sponge. It should be noted that not all sponges can be used as the water-absorbing material of this scheme. Among the sponges, only water-absorbing sponges can be used. At the same time, the surface water-absorbing layer 300 can also be made of non-foamed water-absorbing materials. The optional water-absorbing material scheme can be water-absorbing cloth, water-absorbing fabric, water-absorbing fiber, etc. The use of the above-mentioned water-absorbing material as the surface water-absorbing layer 300 has a more prominent feature that the surface of the surface water-absorbing layer 300 made of the above-mentioned material is continuous and there are no obvious gaps on the surface. In this way, there will be no obvious garbage stuck on the surface of the surface water-absorbing layer 300, and the surface of the surface water-absorbing layer 300 does not hide garbage. Moreover, the surface of the surface water-absorbing layer 300 made of the above material is continuous, and the water adsorbed on the surface is also connected together, so that the water adsorbed on the surface water-absorbing layer 300 will not be easily thrown onto the ground by centrifugal force during the rotation of the surface cleaning roller 10, causing more water stains to remain on the ground.

[0063] Furthermore, in order to reduce the amount of water absorbed in the surface water absorption layer 300, the thickness of the surface water absorption layer 300 can be reduced. A preferred solution is that the thickness of the surface water absorption layer 300 is less than the thickness of the lining buffer layer 200. At the same time, in order to reduce the residual moisture on the ground and avoid the problem that the moisture absorbed in the surface water absorption layer 300 is transferred to the ground when the surface cleaning roller 10 contacts the ground, thereby increasing the residual water on the ground, the thickness of the surface water absorption layer 300 is controlled within 3 mm.

[0064] Furthermore, in order to facilitate the manufacture of the surface cleaning roller 10, the surface water-absorbing layer 300 can also be formed by winding a water-absorbing material along the outer surface of the lining buffer layer 200 for one or several turns. It should be noted that a single piece of water-absorbing material can be used to wind along the outer surface of the lining buffer layer 200 to form a complete surface water-absorbing layer 300, and two or even more pieces of water-absorbing material can also be used to wind around the outer surface of the lining buffer layer 200 to form a complete surface water-absorbing layer 300. Whether a single piece of water-absorbing material or two or even more pieces of water-absorbing material are used to wind around to form the surface water-absorbing layer 300, an overlap portion can be formed on the surface of the surface water-absorbing layer 300. Furthermore, the surface of the surface water absorbing layer 300 has an overlapped portion 3000, and the overlapped portion 3000 is presented as one or more non-spiral overlapped edge profiles 3001 on the surface water absorbing layer 300. The non-spiral overlapped edge profiles 3001 can be straight overlapped edge profiles. In this way, the surface water absorbing layer 300 can be installed on the lining buffer layer 200 very quickly to form a complete surface cleaning roller 10.

[0065] At the same time, further, the surface water absorption layer 300 is formed by winding one or several turns of water absorption material along the outer surface of the lining buffer layer 200 in a spiral winding manner. The surface water absorption layer 300 has an overlap portion 3000 on the surface, and the overlap portion 3000 is presented as one or several spiral overlap edge profiles 3002 in the shape of spiral winding on the surface water absorption layer 300. In the design of having an overlap portion 3000 on the surface water absorption layer 300, making the overlap edge profile into a spiral overlap edge profile 3002 has very important technical significance, which is mainly reflected in: when the surface cleaning roller 10 is installed on the cleaning equipment for work, it needs to be used with a scraper on the cleaning equipment, and the function of the scraper is to scrape off the residual garbage and sewage on the surface cleaning roller 10 (the function of the scraper greatly improves the cleaning efficiency of the cleaning system, and general cleaning equipment needs to design a scraper to scrape the surface of the roller brush or roller). Setting the overlapping edge profile of the overlapping portion 3000 of the surface water-absorbing layer 300 into a spiral shape can ensure that the scraping area of ​​the scraping bar on the overlapping edge profile of the overlapping portion is the same per unit time during the rotation of the surface cleaning roller 10, and the contact surface of the scraping bar of the cleaning equipment on the overlapping portion 3000 of the surface cleaning roller 10 is more uniform, so that the force of the scraping bar of the cleaning equipment on the overlapping portion 3000 of the surface cleaning roller 10 is more uniform, and at the same time, the contact area of ​​the overlapping edge profile of the overlapping portion and the ground per unit time is the same, so that the pressure of the surface cleaning roller 10 on the ground is more uniform, thereby enabling the surface cleaning roller to operate more smoothly on the ground and ensure the stable cleaning performance of the surface cleaning roller 10. In addition, by designing the overlapping edge profile of the overlapping portion 3000 of the surface cleaning roller 10 into a spiral shape, the scraper bar installed in the cleaning equipment will not damage the overlapping portion 3000 of the surface cleaning roller 10 and cause damage to the surface of the surface cleaning roller 10 during the forward and reverse rotation of the surface cleaning roller 10, thereby effectively avoiding the problem of the overlapping edge profile of the overlapping portion 3000 being scratched by the scraper bar, thereby improving the service life of the surface cleaning roller.

[0066] Furthermore, in order to facilitate the design of the overlap portion 3000 and ensure the flatness of the surface of the surface water-absorbing layer 300, the overlap portion 3000 includes a first overlap bevel 3003 and a second overlap bevel 3004. When the water-absorbing material is wrapped around the outer surface of the lining buffer layer 200, the first overlap bevel 3003 and the second overlap bevel 3004 are fixed together by bonding. The surface of the surface water-absorbing layer 300 with a flat surface can be formed by ensuring that the surfaces of the first overlap bevel 3003 and the second overlap bevel 3004 are flush with each other, so that the surface of the surface water-absorbing layer 300 can remain flat without obvious protrusions or pits.

[0067] Furthermore, the overlapping portion can be designed in other ways to ensure the surface flatness of the surface water-absorbing layer 300. In one embodiment, the overlapping portion 3000 includes a first overlapping platform 3005 and a second overlapping platform 3006. The thickness of the first overlapping platform 3005 and the second overlapping platform 3006 are both smaller than the thickness of the water-absorbing material. It can be selected that the thickness of the first overlapping platform plus the thickness of the second overlapping platform is the same as the thickness of the water-absorbing material. An optional implementation method is that when the water-absorbing material is wrapped around the outer surface of the lining buffer layer 200, the first overlapping platform 3005 and the second overlapping platform 3006 are bonded and matched to form a surface water-absorbing layer 300 with a flat surface.

[0068] Furthermore, in order to further reduce the water lock rate of the surface water absorption layer, the surface water absorption layer can be made very thin. In one embodiment, the thickness of the surface water absorption layer 300 can be controlled to be no more than 1 mm. In one embodiment, the water absorption material is wound along the outer surface of the lining buffer layer 200 in a spiral winding manner for at least two turns to form the surface water absorption layer 300. In the direction of spiral winding, the surface water absorption layer 300 at least includes a front circle winding water absorption layer 301 and a rear circle winding water absorption layer 302. During the implementation process, the rear circle winding water absorption layer 302 can at least cover, cover or cover a part of the front circle winding water absorption layer 301. It is understood that the rear circle winding water absorption layer 302 at least presses or covers a part of the structure or a part of the edge of the front circle winding water absorption layer 301. Such a design process is very simple to operate, and the surface water absorption layer 300 can be covered on the outer surface of the lining buffer layer 200 more quickly.

[0069] Furthermore, in order to optimize the surface process of the surface water-absorbing layer 300, the surface of the surface water-absorbing layer 300 is kept smooth. It should be noted here that the smooth surface here is not an absolutely smooth and frictionless surface, but is relative to the description of the surface of the surface water-absorbing layer 300 having an overlap portion 3000 on the surface in the previous embodiment: more specifically defined as, the surface of the surface water-absorbing layer 300 having an overlap portion 3000 and an overlap edge contour on the surface of the surface water-absorbing layer 300 is not a smooth surface; and the surface of the surface water-absorbing layer 300 that does not have an overlap portion 3000 and an overlap edge contour is a smooth surface. In order to make the manufacturing process of the surface cleaning roller 10 simpler, the outer edge of the surface water-absorbing layer 300 can be a smooth surface without any overlap marks, and the surface water-absorbing layer 300 can be directly bonded to the outer surface of the lining buffer layer 200 to directly form the outer surface of the surface cleaning roller 10. The surface cleaning roller produced in this way not only has a simpler manufacturing process, but also has no overlapping edge marks on the surface cleaning layer. In this way, during the operation of the surface cleaning roller 10, the pressure on the ground is more uniform, and the working efficiency of the surface cleaning roller 10 is higher.

[0070] Furthermore, in order to facilitate the disassembly and assembly of the surface cleaning drum 10, an upper handle bracket 20 can be provided on one side of the surface cleaning drum 10. The handle bracket 20 is fixedly mounted on one side of the surface cleaning drum, and the surface cleaning drum 10 can be quickly mounted on or disassembled from the cleaning device through the handle bracket 20. In order to facilitate the operation of the handle bracket, the surface cleaning drum 10 and the handle bracket 20 can be connected by providing a bearing.
