Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and more particularly to a roller brush and cleaning equipment. Background Technology

[0002] A floor scrubber is a cleaning device widely used in various scenarios. Its core function is to remove dust or scrub the floor by having a cloth roller roll into contact with the floor.

[0003] In related technologies, the cloth roller is usually composed of a rigid roller with an inner fixing part (metal or plastic) directly wrapping a cleaning cloth (such as non-woven fabric or sponge cloth), and the outer side of the cloth roller is scraped by a scraper (rigid or elastic scraper) to remove sewage.

[0004] However, the rigid contact between the hard roller and the scraper causes excessive wear on the cleaning cloth fibers, which in turn leads to a significant reduction in the lifespan of the cloth roller. Utility Model Content

[0005] Based on this, this application provides a roller brush and a cleaning device to address the shortcomings of related technologies.

[0006] In a first aspect, this application provides a roller brush component, comprising:

[0007] Support cylinder;

[0008] Cleaning layer, which is fitted onto the support cylinder;

[0009] An elastic structure is connected between the support cylinder and the cleaning layer. The elastic structure has an elastic cavity along the radial direction of the support cylinder. The size of the elastic cavity is greater than or equal to 0.5 mm and less than or equal to 3 mm.

[0010] The roller brush component provided in this application embodiment includes a support cylinder, a cleaning layer, and an elastic structure, the elastic structure including an elastic cavity. The support cylinder supports the elastic structure and the cleaning layer; the cleaning layer cleans the surface to be cleaned; and the elastic structure provides an elastic connection between the support cylinder and the cleaning layer, allowing the cleaning layer to elastically contact the squeegee or the surface to be cleaned, thereby reducing wear on the cleaning layer. The elastic cavity, with its radial dimension between 0.5 mm and 3 mm, provides sufficient deformation space even when the elastic structure is made of materials of different hardness, and the presence of the elastic structure between the support cylinder and the cleaning layer does not excessively increase the radial dimension of the roller brush component.

[0011] In one possible implementation, the elastic structure includes an inner elastic layer and an outer elastic layer spaced apart, a cleaning layer is sleeved on the outer elastic layer, and an elastic cavity is defined between the inner elastic layer and the outer elastic layer.

[0012] Thus, the elastic inner layer is fitted onto the support cylinder, thereby allowing the elastic inner layer to be fixedly connected to the support cylinder, which in turn connects the elastic structure to the support cylinder. The cleaning layer is fitted onto the elastic outer layer, thereby connecting the cleaning layer to the elastic structure. In this way, the cleaning layer, the elastic structure, and the support cylinder are fitted sequentially from the outside to the inside to form a roller brush.

[0013] In one possible implementation, the elastic structure further includes elastic ribs, which are disposed in the elastic cavity and are connected to the inner elastic layer and the outer elastic layer.

[0014] Thus, when the pressure on the cleaning layer is transmitted to the elastic structure, the elastic ribs are compressed. When the pressure on the elastic structure disappears, the elastic ribs can return to their original shape. The elastic ribs can undergo elastic deformation within the elastic cavity, thereby changing the radial dimension of the elastic cavity, thus enabling an elastic connection between the cleaning layer and the support cylinder.

[0015] In one possible implementation, the elastic ribs are spirally arranged along the axial direction of the support cylinder on the outer periphery of the elastic inner layer.

[0016] In this way, the elastic ribs can be supported between the inner and outer elastic layers, and when the elastic ribs are subjected to pressure, they can undergo elastic deformation within the elastic cavity, thereby enabling an elastic connection between the cleaning layer and the support cylinder.

[0017] In one possible implementation, the length of the elastic rib is along the axial direction of the support cylinder, and the width of the elastic rib is inclined relative to the radial direction of the support cylinder.

[0018] Thus, compared to making the width direction of the support cylinder along the radial direction of the support cylinder, the elastic ribs are more likely to move towards the inner elastic layer when subjected to pressure, thereby causing the overall elastic structure to undergo elastic deformation, which is beneficial to improving the buffering performance of the elastic structure.

[0019] In one possible implementation, there are multiple elastic ribs, which are spaced apart circumferentially along the support cylinder, and the multiple elastic ribs are inclined in the same direction.

[0020] In this way, multiple supporting ribs can elastically support various circumferential parts of the elastic outer layer. Furthermore, since multiple elastic ribs maintain the same tilt direction, it is beneficial to reduce the stiffness of the elastic ribs, thereby improving the buffering performance of the elastic structure.

[0021] In one possible implementation, the side of the elastic rib closer to the outer elastic layer is tilted relative to the side closer to the inner elastic layer in the direction of rotation of the elastic rib.

[0022] Thus, when the roller brush rotates, for a single elastic rib, its tilt direction and its rotation direction are on the same side. When the elastic structure is under pressure, the elastic rib is more likely to deform, thereby improving the buffering performance of the elastic structure.

[0023] In one possible implementation, the hardness of the elastic outer layer is less than the hardness of the elastic rib, and the hardness of the elastic rib is less than the hardness of the elastic inner layer.

[0024] This is beneficial for improving the buffering performance of the elastic outer layer in contact with the cleaning layer, maintaining the elastic ribs at a moderate hardness, which is conducive to generating appropriate deformation under pressure, and the elastic inner layer having a high hardness, which can improve the stiffness of the elastic inner layer, thereby improving the structural stability of the elastic structure.

[0025] Secondly, this application provides a cleaning device, including a device body and the roller brush provided in the first aspect, wherein the roller brush is connected to the device body.

[0026] In one possible implementation, the device body includes a housing and a wiping component, the roller brush is rotatably connected to the housing, the wiping component is connected to the housing, the wiping component is located on the outer periphery of the roller brush and contacts the cleaning layer.

[0027] Thus, when the cleaning equipment uses the roller brush provided in the first aspect, since the cleaning layer and the support cylinder are elastically connected through an elastic structure, when there is a lot of sewage on the cleaning layer that needs to be scraped off, the squeegee can abut against the cleaning layer, and the roller brush remains in a rotating state. The sewage on the cleaning layer is scraped off by the squeegee, and the cleaning layer and the squeegee are in elastic contact, which can prevent the squeegee from causing excessive wear on the cleaning layer.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0056] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0057] Floor scrubbers are cleaning devices widely used in various scenarios. Their core function is to remove dust or scrub the floor by having a cloth roller roll into contact with the surface. In related technologies, the cloth roller typically consists of a rigid roller with an inner fixing component (metal or plastic) directly wrapping a cleaning cloth (such as non-woven fabric or sponge cloth), while a scraper (rigid or flexible squeegee) removes wastewater from the outside of the roller. However, the rigid contact between the rigid roller and the scraper causes excessive wear on the cleaning cloth fibers, significantly shortening the roller's lifespan.

[0058] Alternatively, in related technologies, the fabric roller is adjusted by a floating mechanism. However, this causes the rotation axis of the fabric roller to not coincide with its geometric center, which in turn causes the fabric roller to vibrate periodically when rotating at high speed, making it easy for hair to get tangled on the fabric roller.

[0059] In view of the above problems, this application provides a roller brush and a cleaning device. The roller brush has an elastic cavity between the support cylinder and the cleaning layer, and the height of the elastic cavity is set between 0.5 mm and 3 mm so that the elastic structure has a certain deformation space. When the cleaning layer comes into contact with the wiper, the elastic structure can buffer the contact pressure between the cleaning layer and the wiper, thereby reducing the wear of the cleaning layer and improving the service life of the roller brush.

[0060] The specific implementation of the roller brush and cleaning equipment provided in this application will be described in detail below with reference to the accompanying drawings.

[0061] Reference Figure 1 As shown in the figure, this application embodiment provides a cleaning device, which includes a roller brush 10 and a device body 20, with the roller brush 10 connected to the device body 20.

[0062] It is understood that the cleaning equipment can be a vacuum cleaner, a floor scrubber, or a robot vacuum cleaner, and this application does not limit it in this respect.

[0063] The roller brush 10 can be rotatably connected to the device body 20, so that when the cleaning device moves on the surface to be cleaned, the roller brush 10 can roll relative to the surface to be cleaned, thereby cleaning the surface to be cleaned.

[0064] Reference Figures 2 to 6 As shown, based on the above embodiments, this application provides a roller brush 10, which includes a support cylinder 100, a cleaning layer 200 and an elastic structure 300. The cleaning layer 200 is sleeved on the support cylinder 100, and the elastic structure 300 is connected between the support cylinder 100 and the cleaning layer 200.

[0065] The elastic structure 300 has an elastic cavity 310 along the radial direction of the support cylinder 100. The size of the elastic cavity 310 is greater than or equal to 0.5 mm and less than or equal to 3 mm.

[0066] In this embodiment, the support cylinder 100 supports the cleaning layer 200, and the support cylinder 100 can be rotatably connected to the device body 20, thereby causing the roller brush 10 to rotate relative to the device body 20. The cleaning layer 200 is used to contact the surface to be cleaned, so that the wet cleaning layer 200 can perform wet mopping on the surface to be cleaned, or the cleaning device can vacuum the surface to be cleaned. Under the action of suction, the cleaning layer 200 can help peel off the dirt attached to the surface to be cleaned.

[0067] Because an elastic structure 300 is provided between the cleaning layer 200 and the support cylinder 100, the elastic structure 300 enables an elastic connection between the cleaning layer 200 and the support cylinder 100. Furthermore, because the elastic structure 300 has an elastic cavity 310, the elastic cavity 310 can provide deformation space for the elastic structure 300. When the roller brush 10 is subjected to pressure, the elastic structure 300 is compressed radially along the support cylinder 100, thereby producing a certain deformation. When the pressure on the roller brush 10 decreases or disappears, the elastic structure 300 returns to its original shape radially along the support cylinder 100, thereby enabling the roller brush 10 to adapt to changes based on the pressure acting on it.

[0068] In this way, when the squeegee 202 wipes the cleaning layer 200, the squeegee 202 and the cleaning layer 200 make elastic contact, which avoids the cleaning layer 200 from being severely worn due to rigid contact, thereby improving the service life of the cleaning layer 200. Furthermore, when cleaning the surface to be cleaned, the elastic structure 300 allows the cleaning layer 200 to make elastic contact with the surface to be cleaned, ensuring that the cleaning layer 200 always maintains a close contact with the surface to be cleaned, thus improving the cleaning effect of the roller brush 10.

[0069] The radial dimension of the elastic cavity 310 along the support cylinder 100 can be between 0.5 mm and 3 mm. On the one hand, if the radial dimension of the elastic cavity 310 along the support cylinder 100 is less than 0.5 mm, the spatial dimension of the elastic cavity 310 is small, and the elastic structure 300 does not have sufficient deformation space. On the other hand, if the radial dimension of the elastic cavity 310 along the support cylinder 100 is greater than 3 mm, it will result in a larger size of the elastic structure 300, which in turn will result in a larger radial dimension of the roller brush 10, thus making the roller brush 10 unable to fit the existing equipment body 20.

[0070] Therefore, in this embodiment, the radial dimension of the elastic cavity 310 along the support cylinder 100 is between 0.5 mm and 3 mm, which allows the elastic structure 300 to have sufficient deformation space and to balance the overall radial dimension of the roller brush 10.

[0071] In specific implementation, the elastic structure 300 can be made of materials such as silicone rubber, thermoplastic polyurethane or natural rubber. The Shore hardness of the material selected for the elastic structure 300 can be between 20A and 80A. The radial dimension of the elastic cavity 310 along the support cylinder 100 can be matched with the hardness of the selected material. When the hardness of the material is greater, the radial dimension of the elastic cavity 310 along the support cylinder 100 can be larger. When the hardness of the material is smaller, the radial dimension of the elastic cavity 310 along the support cylinder 100 can be smaller.

[0072] For example, when the elastic structure 300 is made of silicone rubber with a Shore hardness of 30A-50A, the elastic modulus of the silicone rubber is between 2.5MPa and 6MPa, and the deformation of the elastic structure 300 is relatively large. In this case, the radial dimension of the elastic cavity 310 along the support cylinder 100 can be set to 2mm to 3mm to ensure that the elastic cavity 310 can provide sufficient deformation margin, thereby preventing the elastic structure 300 from failing under large pressure.

[0073] For example, when the elastic structure 300 is made of medium-hardness silicone rubber with a Shore hardness of 50A-70A, the elastic modulus of the silicone rubber is between 6MPa and 15MPa, and the deformation of the elastic structure 300 is moderate. In this case, the radial dimension of the elastic cavity 310 along the support cylinder 100 can be set to 1mm to 2mm. The deformation of the elastic structure 300 is adapted to the size of the elastic cavity 310, which can improve the buffering capacity of the elastic structure 300 to cope with pressure, thereby enabling the cleaning layer 200 and the wiper 202 to achieve elastic contact.

[0074] For example, when the elastic structure 300 is made of relatively hard silicone rubber with a Shore hardness of 70A-80A, the elastic modulus of the silicone rubber is between 15MPa and 25MPa, and the deformation of the elastic structure 300 is relatively small. In this case, the radial dimension of the elastic cavity 310 along the support cylinder 100 can be set to 0.5mm to 1mm, which can provide sufficient deformation space for the elastic structure 300 while maintaining the overall rigidity of the elastic structure 300. Moreover, for a relatively hard elastic structure 300, setting the size of the elastic cavity 310 too large will not only increase the size of the roller brush 10, but also lead to structural redundancy.

[0075] The roller brush 10 provided in this embodiment includes a support cylinder 100, a cleaning layer 200, and an elastic structure 300, the elastic structure 300 including an elastic cavity 310. The support cylinder 100 supports the elastic structure 300 and the cleaning layer 200. The cleaning layer 200 cleans the surface to be cleaned. The elastic structure 300 provides an elastic connection between the support cylinder 100 and the cleaning layer 200, allowing the cleaning layer 200 to elastically contact the wiper 202 or the surface to be cleaned, thereby reducing wear on the cleaning layer 200. The elastic cavity 310, with its radial dimension between 0.5 mm and 3 mm, provides sufficient deformation space even when the elastic structure 300 is made of materials of different hardness. Furthermore, placing the elastic structure 300 between the support cylinder 100 and the cleaning layer 200 does not excessively increase the radial dimension of the roller brush 10.

[0076] Reference Figure 6 As shown, in one possible implementation, the elastic structure 300 includes an inner elastic layer 320 and an outer elastic layer 330 spaced apart from each other. The inner elastic layer 320 is sleeved on the support cylinder 100, and the cleaning layer 200 is sleeved on the outer elastic layer 330. An elastic cavity 310 is defined between the inner elastic layer 320 and the outer elastic layer 330.

[0077] In this way, the elastic inner layer 320 is sleeved on the support cylinder 100, thereby allowing the elastic inner layer 320 to be fixedly connected to the support cylinder 100, and the elastic structure 300 to be connected to the support cylinder 100. The cleaning layer 200 is sleeved on the elastic outer layer 330, thereby allowing the cleaning layer 200 to be connected to the elastic structure 300. Thus, the cleaning layer 200, the elastic structure 300, and the support cylinder 100 are sequentially sleeved from the outside to the inside to form the roller brush 10.

[0078] The elastic inner layer 320 can be interference-fitted with the support cylinder 100.

[0079] In some embodiments, air can be filled into the elastic cavity 310 so that the elastic structure 300 forms an air bladder. When the elastic structure 300 is subjected to pressure, the volume of the elastic cavity 310 decreases. When the pressure on the elastic structure 300 disappears, the elastic cavity 310 returns to its original volume, thereby enabling the cleaning layer 200 and the support cylinder 100 to achieve an elastic connection.

[0080] Reference Figures 5 to 8 As shown, in some embodiments, the elastic structure 300 further includes elastic ribs 340, which are disposed in the elastic cavity 310 and are all connected to the elastic inner layer 320 and the elastic outer layer 330.

[0081] With this configuration, when the pressure on the cleaning layer 200 is transmitted to the elastic structure 300, the elastic rib 340 is compressed. When the pressure on the elastic structure 300 disappears, the elastic rib 340 can return to its original shape. The elastic rib 340 can undergo elastic deformation within the elastic cavity 310, thereby causing a change in the radial dimension of the elastic cavity 310, thus enabling an elastic connection between the cleaning layer 200 and the support cylinder 100.

[0082] Reference Figure 7 and Figure 8 As shown, in some embodiments, the elastic rib 340 is spirally disposed on the outer periphery of the elastic inner layer 320 along the axial direction of the support cylinder 100.

[0083] With this configuration, the elastic rib 340 can be supported between the elastic inner layer 320 and the elastic outer layer 330, and when the elastic rib 340 is subjected to pressure, it can undergo elastic deformation within the elastic cavity 310, thereby enabling an elastic connection between the cleaning layer 200 and the support cylinder 100.

[0084] The pitch of the elastic rib 340 can be set according to the length of the roller brush 10, and this embodiment does not impose specific restrictions on it.

[0085] Reference Figure 6 As shown, in some embodiments, the length direction of the elastic rib 340 is along the axial direction of the support cylinder 100, and the width direction of the elastic rib 340 is inclined relative to the radial direction of the support cylinder 100.

[0086] Thus, compared to the width direction of the support cylinder 100 being along the radial direction of the support cylinder 100, the elastic rib 340 is more likely to move towards the elastic inner layer 320 when subjected to pressure, thereby causing the elastic structure 300 to undergo elastic deformation as a whole, which is beneficial to improving the buffering performance of the elastic structure 300.

[0087] Reference Figure 6 As shown, in one possible implementation, there are multiple elastic ribs 340, which are spaced apart circumferentially along the support cylinder 100, and the multiple elastic ribs 340 have the same inclination direction.

[0088] In this way, multiple support ribs can elastically support various circumferential parts of the elastic outer layer 330. Furthermore, since the multiple elastic ribs 340 maintain the same tilt direction, it is beneficial to reduce the stiffness of the elastic ribs 340, thereby improving the buffering performance of the elastic structure 300.

[0089] Reference Figure 6 As shown, in one possible implementation, the side of the elastic rib 340 closest to the outer elastic layer 330 is inclined toward the rotation direction of the elastic rib 340 relative to the side closest to the inner elastic layer 320.

[0090] It should be noted that, taking the end where the elastic rib 340 connects to the inner elastic layer 320 as the starting point and the end where the elastic rib 340 connects to the outer elastic layer 330 as the ending point, a directed line segment is drawn, which forms an acute angle with the rotation direction of the elastic rib 340. It should also be noted that, since multiple elastic ribs 340 are spaced apart circumferentially along the support cylinder 100, the multiple elastic ribs 340 described in the above embodiments refer to the same elastic rib 340.

[0091] In this way, when the roller brush 10 rotates, for a single elastic rib 340, its tilt direction and its rotation direction are on the same side. When the elastic structure 300 is subjected to pressure, the elastic rib 340 is more likely to deform, thereby improving the buffering performance of the elastic structure 300.

[0092] In one possible implementation, the hardness of the elastic outer layer 330 is less than the hardness of the elastic rib 340, and the hardness of the elastic rib 340 is less than the hardness of the elastic inner layer 320.

[0093] In other words, the hardness of the elastic outer layer 330, the elastic rib 340, and the elastic inner layer 320 gradually increases. This is beneficial to improving the buffering performance of the elastic outer layer 330 in contact with the cleaning layer 200. The elastic rib 340 maintains a medium hardness, which is beneficial to it to produce appropriate deformation under pressure. The elastic inner layer 320 has a high hardness, which can improve the stiffness of the elastic inner layer 320 and thus improve the structural stability of the elastic structure 300.

[0094] Reference Figure 1 and Figure 9 As shown, in one possible implementation, the device body 20 includes a housing 201 and a wiping component 202. The roller brush 10 is rotatably connected to the housing 201, and the wiping component 202 is connected to the housing 201. The wiping component 202 is located on the outer periphery of the roller brush 10 and is in contact with the cleaning layer 200.

[0095] It should be understood that when the cleaning equipment uses the roller brush 10 provided in the above embodiment, since the cleaning layer 200 and the support cylinder 100 are elastically connected through the elastic structure 300, when there is a lot of sewage on the cleaning layer 200 that needs to be scraped off, the squeegee 202 can abut against the cleaning layer 200, and the roller brush 10 remains in a rotating state. The sewage on the cleaning layer 200 is then scraped off by the squeegee 202. Furthermore, the cleaning layer 200 and the squeegee 202 are in elastic contact, thus preventing excessive wear on the cleaning layer 200 caused by the squeegee 202. In addition, since the axis of rotation and the geometric center line of the roller brush 10 in this embodiment remain consistent when rotating, hair can be effectively prevented from getting tangled on the roller brush 10.

[0096] Reference Figures 2 to 4As shown, in some embodiments, the roller brush 10 may also include a mounting portion 400, which is connected to the housing 201, thereby mounting the roller brush 10 onto the housing 201.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
