Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a side brush assembly and a cleaning device. Background Technology

[0002] With the development of smart homes, household cleaning equipment is becoming increasingly popular. Taking robot vacuums as an example, the side brush component, as an important part of robot vacuums, can sweep debris from edges and corners into the cleaning range of the main brush, thereby improving the cleaning effect.

[0003] However, when existing robotic vacuum cleaners come into contact with surfaces such as floors and carpets during operation, the side brushes may lift up due to the high friction, which can affect their cleaning performance. Utility Model Content

[0004] The purpose of this application is to provide a side brush assembly and cleaning device, which aims to solve the problem in the related art that the side brush assembly is easily subjected to large frictional forces, causing it to lift up and affecting the cleaning effect.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] In a first aspect, embodiments of this application provide a cleaning device, including a device body and a side brush assembly. The side brush assembly is used to clean a target object from the opposite direction. The side brush assembly includes a side brush bracket, a fixing structure, and a bristle-embedding structure. The side brush bracket is rotatably disposed at the bottom of the device body and is configured to rotate relative to the device body. The fixing structure is connected to the side brush bracket, and the bristle-embedding structure is connected to the fixing structure. The side brush assembly also includes guide ribs, and the surface area of ​​the guide ribs facing the target object is smaller than the surface area of ​​the fixing structure facing the target object.

[0007] The beneficial effects of the embodiments of this application are as follows: The cleaning equipment provided in this application has a side brush bracket that can rotate relative to the main body of the equipment, thereby driving the fixed structure and the bristle structure to rotate synchronously so that the bristle structure can perform cleaning operations; at the same time, a guide rib is provided on the side of the fixed structure facing away from the main body of the equipment. When the fixed structure and the bristle structure rotate and clean the target object, the guide rib can replace the fixed structure to contact the target object. Moreover, the surface area of ​​the guide rib facing the target object is smaller, so the friction force on the guide rib is smaller. The probability of the guide rib and the fixed structure folding due to friction, causing the bristle structure to lift up and leave the target object, is smaller, so as to ensure the cleaning efficiency of the cleaning equipment.

[0008] In some embodiments, the guide bone position includes a first side surface, a second side surface, and a guide surface. One end of the first side surface and the second side surface are respectively connected to a fixing structure, and the other end of the first side surface and the second side surface are respectively connected to the guide surface. The guide surface faces the target object. The first side surface is a concave arc surface.

[0009] In some embodiments, there are two fixing structures, which are symmetrically arranged on the side brush bracket about the axial direction of the side brush bracket; each of the two fixing structures is provided with a bristle-planting structure.

[0010] In some embodiments, the fixing structure is arc-shaped, with the outer arc surface of the fixing structure facing the rotation direction of the side brush bracket.

[0011] In some embodiments, the fixing structure has a first end and a second end, the first end being connected to the side brush bracket and the second end being connected to the bristle-embedding structure; the distance between the first end and the device body is less than the distance between the second end and the device body.

[0012] In some embodiments, the guide bone includes a first guide portion and a second guide portion, both of which are disposed on the side of the fixing structure facing away from the main body of the device, and the first guide portion and the second guide portion are disposed sequentially from the first end to the second end.

[0013] In some embodiments, the projections of the two tufts of hair structures are arranged in parallel in any plane in the axial direction perpendicular to the side brush holder.

[0014] In some embodiments, the guide bone position and the fixation structure are integrally formed.

[0015] In some embodiments, two sets of side brush assemblies are symmetrically arranged at the bottom of the device body, and the two sets of side brush assemblies rotate in opposite directions; in the forward direction along the device body, both sets of side brush assemblies rotate toward the center of the bottom of the device body.

[0016] In some embodiments, the cleaning device further includes a drive unit disposed within the device body, and the output end of the drive unit is connected to the side brush bracket.

[0017] Secondly, this application embodiment also provides a side brush assembly, which includes a side brush bracket, a fixing structure, and a bristle implantation structure; the side brush bracket is rotatably disposed at the bottom of the device body, and the side brush bracket is configured to rotate relative to the device body; the fixing structure is connected to the side brush bracket, and the bristle implantation structure is connected to the fixing structure; wherein, the side brush assembly also includes a guide rib, which is disposed on the side of the fixing structure facing away from the device body; the guide rib protrudes from the fixing structure in the direction facing away from the device body.

[0018] The beneficial effects of the embodiments of this application are as follows: When the side brush assembly provided in the embodiments of this application rotates and cleans the target object, the guide bone can replace the fixed structure to contact the target object, and the surface area of ​​the guide bone facing the target object is smaller, so the friction force on the guide bone is smaller. The probability that the guide bone and the fixed structure will be folded due to friction and cause the bristle structure to lift up and leave the target object is smaller, thereby effectively ensuring the cleaning efficiency of the side brush assembly.

Detailed Implementation

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0030] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in 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.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of 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.

[0033] With the development of smart homes, household cleaning equipment is becoming increasingly popular. Taking robot vacuums as an example, the side brush component, as an important part of robot vacuums, can sweep debris from edges and corners into the cleaning range of the main brush, thereby improving the cleaning effect.

[0034] However, when existing robotic vacuum cleaners come into contact with surfaces such as floors and carpets during operation, the side brushes may lift up due to the high friction, which can affect their cleaning performance.

[0035] Based on the above considerations, in order to solve the problem that the side brush assembly in related technologies is prone to warping due to high friction, affecting the cleaning effect, a cleaning device is designed. The side brush bracket of the cleaning device can rotate relative to the main body of the device, thereby driving the fixed structure and the bristle structure to rotate synchronously so that the bristle structure can perform cleaning operations. At the same time, a guide rib is provided on the side of the fixed structure facing away from the main body of the device. When the fixed structure and the bristle structure rotate and clean the target object, the guide rib can replace the fixed structure to contact the target object. Moreover, the surface area of ​​the guide rib facing the target object is smaller, thus the friction force on the guide rib is smaller. The probability of the guide rib and the fixed structure folding due to friction, causing the bristle structure to warp and leave the target object, is smaller, so as to ensure the cleaning efficiency of the cleaning device.

[0036] For ease of description, we will take a robotic vacuum cleaner as an example to provide a detailed description of the cleaning equipment provided in this application.

[0037] Please refer to Figures 1 to 4 This application provides a cleaning device 1000, including a device body 100 and a side brush assembly 200. The side brush assembly 200 is used to clean a target object from the opposite direction. The side brush assembly 200 includes a side brush bracket 210, a fixing structure 220, and a bristle-embedding structure 230. The side brush bracket 210 is rotatably disposed at the bottom of the device body 100 and is configured to rotate relative to the device body 100. The fixing structure 220 is connected to the side brush bracket 210, and the bristle-embedding structure 230 is connected to the fixing structure 220. The side brush assembly 200 also includes a guide rib 240, the surface area of ​​the guide rib 240 facing the target object is smaller than the surface area of ​​the fixing structure 220 facing the target object.

[0038] The target objects mentioned above refer to objects that need to be cleaned, such as floors and carpets.

[0039] The equipment body 100 refers to the main structure of the cleaning equipment 1000, including the main parts such as the shell structure and internal control structure of the cleaning equipment 1000. Optionally, the equipment body 100 may also include cleaning devices such as a suction port and a main brush structure, using the main brush for sweeping and the suction port for vacuuming.

[0040] The side brush assembly 200 refers to a component used to perform sweeping and brushing functions; the side brush assembly 200 is typically located on the bottom side of the main body 100 of the device. The main function of the side brush assembly 200 is to clean walls, corners, and other hard-to-reach areas when the cleaning device 1000 is running; the side brush assembly 200 sweeps dust, dirt, and debris from edge areas or corners towards the area directly under the main body 100 of the cleaning device 100 by rotating, so that the main body 100 can vacuum or clean.

[0041] The side brush assembly 200 includes a side brush bracket 210; the side brush bracket 210 refers to a bracket structure rotatably mounted on the bottom of the main body 100 of the device. Optionally, the side brush bracket 210 may be, but is not limited to, a circular bracket, a rectangular bracket, a spherical bracket, or other configurations.

[0042] The side brush bracket 210 is configured to rotate relative to the main body 100; thus, the side brush bracket 210 can drive the fixed structure 220 and the bristle structure 230 to rotate synchronously relative to the main body 100, so as to realize the rotation cleaning operation of the entire side brush assembly 200.

[0043] The fixing structure 220 refers to the structure connected to the side brush bracket 210 and used to fix the bristle structure 230. Optionally, the number of fixing structures 220 can be one, two, or three; the fixing structure 220 can be, but is not limited to, a block structure, a rod structure, a protruding structure, etc.; the material of the fixing structure 220 can be a wear-resistant material with a certain degree of elasticity. The fixing structure 220 can be connected to the side brush bracket 210 to form an integral unit through snap-fit, heat fusion connection, fastener connection, integral molding, etc.

[0044] For example, in some embodiments, the fixing structure 220 can be a rod-shaped structure, such as an arc-shaped rod-shaped structure; one end of the rod-shaped structure is connected to the side brush bracket 210, and the other end of the rod-shaped structure is used to connect to the bristle-planting structure 230; in this way, when the side brush bracket 210 rotates, the fixing structure 220 can drive the bristle-planting structure 230 to rotate synchronously to achieve the cleaning operation.

[0045] The side brush assembly 200 also includes a bristle structure 230; it can be understood that the bristle structure 230 refers to a bundle of bristles fixedly mounted on the fixed structure 220. When the side brush bracket 210 rotates, the bristle structure 230 can rotate synchronously and perform cleaning operations on the surface of the target object (such as the floor, carpet, etc.).

[0046] The side brush assembly 200 also includes a guide rib 240; the guide rib 240 refers to a structure that is disposed on the fixed structure 220 and is outwardly protruding. Optionally, the guide rib 240 can be connected to the fixed structure 220 to form an integral unit by means of bonding, fastener connection, snap-fit ​​connection, integral molding, etc.

[0047] The guide rib 240 can be of any configuration; for example, it can be roughly triangular, trapezoidal, semi-circular, etc. The guide rib 240 is located on the side of the fixed structure 220 facing away from the main body 100, i.e., the guide rib 240 is located on the side of the fixed structure 220 facing the target object. It should be understood that when the cleaning equipment 1000 performs cleaning operations, the side brush assembly 200 rotates to sweep, and at this time, the gap between the guide rib 240 and the target object is smaller than the gap between the fixed structure 220 and the target object; for example, the guide rib 240 can partially abut against the surface of the target object. Thus, during the sweeping process of the side brush assembly 200, the guide rib 240 replaces the fixed structure 220 in contact with the target object such as the floor or carpet.

[0048] The surface area of ​​the guide rib 240 facing the target object is smaller than the surface area of ​​the fixed structure 220 facing the target object. It should be understood that the surface area of ​​the guide rib 240 facing the target object refers to the area where the guide rib 240 contacts the target object; for example, when the surface of the guide rib 240 facing the target object is a plane, the area of ​​that plane is the area in contact with the target object; or, when the surface of the guide rib 240 facing the target object is a curved surface, the area of ​​the curved surface in contact with the target object is the area in contact with the target object.

[0049] The cleaning device 1000 provided in this application embodiment has a side brush bracket 210 that can rotate relative to the main body 100, thereby driving the fixed structure 220 and the bristle structure 230 to rotate synchronously so that the bristle structure 230 can perform cleaning operations. At the same time, a guide rib 240 is provided on the side of the fixed structure 220 facing away from the main body 100. When the fixed structure 220 and the bristle structure 230 rotate and clean the target object, the guide rib 240 can replace the fixed structure 220 to contact the target object. Moreover, the surface area of ​​the guide rib 240 facing the target object is smaller, so the friction force on the guide rib 240 is smaller. The probability that the guide rib 240 and the fixed structure 220 will bend due to friction and cause the bristle structure 230 to lift up and leave the target object is smaller, so as to ensure the cleaning efficiency of the cleaning device 1000.

[0050] Please refer to Figures 1 to 5 In some embodiments, the guide bone position 240 includes a first side 2401, a second side 2402, and a guide surface 2403. One end of the first side 2401 and the second side 2402 are respectively connected to the fixing structure 220, and the other opposite ends of the first side 2401 and the second side 2402 are respectively connected to the guide surface 2403. The guide surface 2403 faces the target object. The first side 2401 is a concave arc surface.

[0051] It should be understood that the first side 2401 and the second side 2402 refer to the two end walls of the guide bone position 240 on the periphery; thus, both the first side 2401 and the second side 2402 are connected to the fixation structure 220.

[0052] The guide surface 2403 refers to the surface facing the target object and used to form contact with the target object; the first side surface 2401 and the second side surface 2402 are connected to the guide surface 2403 at the other end of the connecting and fixing structure 220.

[0053] The first side surface 2401 is a concave arc surface; optionally, the first side surface 2401 can be an arc surface of any curvature. By setting the first side surface 2401 as an arc surface, the end of the first side surface 2401 facing the target object is inclined towards the second side surface 2402; thus, the area of ​​the guide surface 2403 can be set to be smaller.

[0054] This configuration allows the guide bone position 240 to provide guidance and support for the fixation structure 220, effectively reducing the probability of the fixation structure 220 deforming due to excessive friction.

[0055] Please refer to Figures 1 to 4 In some embodiments, there are two fixing structures 220, which are symmetrically arranged on the side brush bracket 210 about the axial direction of the side brush bracket 210; each of the two fixing structures 220 is provided with a bristle-planting structure 230.

[0056] Two fixed structures 220 are symmetrically arranged on the side brush bracket 210 about the axial direction. In this way, after one of the fixed structures 220 rotates 180° from its initial position about the axial direction of the side brush bracket 210, it can coincide with the initial position of the other fixed structure 220.

[0057] In this embodiment, the number of fixing structures 220 is limited to two. This setting changes the conventional design of three fixing structures 220 and three bundles of hair-planting structures 230 to a design of two fixing structures 220 and two bundles of hair-planting structures 230, which can reduce the number of bundles of hair-planting structures 230 and effectively increase the spacing between hair-planting structures 230. As a result, the spacing between adjacent hair-planting structures 230 is larger, and the probability of hair, wires, etc. getting tangled on the hair-planting structures 230 and fixing structures 220 is also lower.

[0058] Please refer to Figures 1 to 4 In some embodiments, the fixing structure 220 is arc-shaped, and the outer arc surface of the fixing structure 220 faces the rotation direction of the side brush bracket 210.

[0059] The fixed structure 220 has an arc-shaped structure; it should be understood that the surface of the fixed structure 220 facing away from the center of curvature of its arc-shaped structure is the outer arc surface, and the surface of the fixed structure 220 facing the center of curvature of its arc-shaped structure is the inner arc surface.

[0060] In this embodiment, the outer arc surface of the fixing structure 220 faces the rotation direction of the side brush bracket 210. Thus, when the side brush bracket 210 rotates and drives the fixing structure 220 to rotate, the outer arc surface of the fixing structure 220 faces the rotation direction of the side brush bracket 210 and rotates forward. Compared to the state where the inner arc surface of the fixing structure 220 faces the rotation direction of the side brush bracket 210, when the outer arc surface faces the rotation direction of the side brush bracket 210, hair, wires, etc., tend to move outward under the push of the fixing structure 220 and the guide bone 240, due to the arc shape of the outer arc surface of the fixing structure 220. Therefore, the fixing structure 220 is less likely to entangle hair, etc.

[0061] Please refer to Figures 1 to 4 In some embodiments, the fixing structure 220 has a first end 221 and a second end 222, the first end 221 being connected to the side brush bracket 210 and the second end 222 being connected to the bristle-planting structure 230; the distance between the first end 221 and the device body 100 is less than the distance between the second end 222 and the device body 100.

[0062] Here, the first end 221 and the second end 222 refer to two different ends of the fixing structure 220. For example, in some embodiments, the fixing structure 220 can be an arc-shaped rod structure; thus, the opposite ends of the arc-shaped rod structure are the first end 221 and the second end 222.

[0063] The first end 221 is connected to the side brush; optionally, the first end 221 can be connected to the side brush bracket 210 by means of bonding, snap-fit ​​connection, integral molding, etc.

[0064] The second end 222 is connected to the hair-planting structure 230; it is understood that the hair bundles in the hair-planting structure 230 can be fixed to the second end 222 by hair-planting or by heat-fusion connection, snap-fit, etc.

[0065] The distance between the first end 221 and the main body 100 is less than the distance between the second end 222 and the main body 100; that is, the first end 221 connected to the side brush bracket 210 is closer to the main body 100, and the first end 221 connected to the side brush bracket 210 is farther from the target object; at the same time, the second end 222 connected to the bristle structure 230 is farther from the main body 100, and the second end 222 connected to the bristle structure 230 is closer to the target object.

[0066] With this configuration, when the cleaning equipment 1000 is performing a cleaning operation, the bristle structure 230 can get closer to the target object or form contact with the target object to ensure the cleaning effect of the bristle structure 230 on the target object; at the same time, the first end 221 of the side brush bracket 210 is far away from the target object to prevent the target object from affecting the rotation of the side brush bracket 210 and thus affecting the cleaning effect of the side brush assembly 200.

[0067] Please refer to Figures 1 to 4 In some embodiments, the guide bone position 240 includes a first guide portion 241 and a second guide portion 242. The first guide portion 241 and the second guide portion 242 are both disposed on the side of the fixing structure 220 facing away from the device body 100, and the first guide portion 241 and the second guide portion 242 are arranged sequentially from the first end 221 to the second end 222.

[0068] Understandably, the first guide portion 241 and the second guide portion 242 refer to two parts of the guide bone position 240. Optionally, the first guide portion 241 and the second guide portion 242 can be an integral structure; or, the first guide portion 241 and the second guide portion 242 can be a separate structure.

[0069] For example, in some embodiments, the first guide portion 241 may be, but is not limited to, a semi-circular protrusion, an arc-shaped protrusion, a triangular protrusion, a trapezoidal protrusion, etc.; the second guide portion 242 may be, but is not limited to, a semi-circular protrusion, an arc-shaped protrusion, a triangular protrusion, a trapezoidal protrusion, etc.

[0070] The first guide portion 241 and the second guide portion 242 are arranged sequentially from the first end 221 to the second end 222. For example, when the fixing structure 220 is an arc-shaped rod structure, the first guide portion 241 and the second guide portion 242 can be arranged sequentially along the length direction of the fixing structure 220, and the first guide portion 241 is closer to the first end 221, and the second guide portion 242 is closer to the second end 222.

[0071] Meanwhile, the second end 222 is closer to the target object than the first end 221; thus, the second guide portion 242, which is closer to the second end 222, is closer to the target object.

[0072] With this configuration, the first guide part 241 and the second guide part 242 can form a two-level guiding effect on the fixed structure 220. That is, the second guide part 242, which is closer to the target object, can contact the target object such as the ground or carpet, while the first guide part 241, which is farther away from the target object, can make secondary contact. This can adapt to various terrains and further reduce the probability that the fixed structure 220 will deform due to excessive force, causing the flocking structure 230 to lift up.

[0073] Please refer to Figures 1 to 4In some embodiments, the projections of the two tufts of hair-planting structures 230 are arranged in parallel in any plane in the axial direction perpendicular to the side brush holder 210.

[0074] With this configuration, the cleaning paths of the two bundles of bristle structures 230 located on the two fixed structures 220 are roughly the same; as the two fixed structures 220 rotate, the two bundles of bristle structures 230 can sweep through the same path, so as to ensure the cleaning consistency of the two bundles of bristle structures 230 when rotating synchronously.

[0075] Please refer to Figures 1 to 4 In some embodiments, the guide bone position 240 is integrally formed with the fixation structure 220.

[0076] In this embodiment, the guide rib 240 and the fixing structure 220 are integrally formed, which can improve the connection strength between the guide rib 240 and the fixing structure 220; thus making the guide rib 240 more durable and effectively improving the structural strength of the guide rib 240 and the entire side brush assembly 200.

[0077] Please refer to Figures 1 to 4 In some embodiments, two sets of side brush assemblies 200 are symmetrically arranged at the bottom of the device body 100, and the two sets of side brush assemblies 200 rotate in opposite directions; in the forward direction along the device body 100, both sets of side brush assemblies 200 rotate toward the center of the bottom of the device body 100.

[0078] With this configuration, two sets of side brush assemblies 200 simultaneously perform cleaning operations at the bottom of the main body 100, and the two sets of side brush assemblies 200 rotate in opposite directions. Thus, along the forward direction of the main body 100, both sets of side brush assemblies 200 rotate towards the center of the bottom of the main body 100, and the two sets of side brush assemblies 200 can effectively sweep the garbage that is difficult to clean from the corners into the lower part of the main body 100, so as to facilitate the cleaning operation of the main body 100.

[0079] Please refer to Figures 1 to 4 In some embodiments, the cleaning device 1000 further includes a drive unit (not shown in the figure), which is disposed within the device body 100, and the output end of the drive unit is connected to the side brush bracket 210.

[0080] Optionally, the driving device can be a drive motor or other driving component. The output end of the driving device is connected to the side brush bracket 210 and the side brush bracket 210 is driven to rotate, so as to realize the rotation cleaning operation of the side brush assembly 200.

[0081] Please refer to Figures 1 to 4This application embodiment also provides a side brush assembly 200, which includes a side brush bracket 210, a fixing structure 220, and a bristle implantation structure 230. The side brush bracket 210 is rotatably disposed at the bottom of the device body 100 and is configured to rotate relative to the device body 100. The fixing structure 220 is connected to the side brush bracket 210, and the bristle implantation structure 230 is connected to the fixing structure 220. The side brush assembly 200 also includes a guide rib 240, which is disposed on the side of the fixing structure 220 facing away from the device body 100. The guide rib 240 protrudes from the fixing structure 220 in a direction facing away from the device body 100.

[0082] The side brush assembly 200 provided in this application embodiment can be applied to the cleaning device 1000 described above, for example, mounted on the bottom side of a sweeping robot. When the side brush assembly 200 rotates and cleans the target object, the guide rib 240 can replace the fixed structure 220 to contact the target object, and the surface area of ​​the guide rib 240 facing the target object is smaller, thereby reducing the friction force on the guide rib 240. The probability that the guide rib 240 and the fixed structure 220 will be folded due to friction, causing the bristle structure 230 to lift up and leave the target object, is smaller, thus effectively ensuring the cleaning efficiency of the side brush assembly 200.

[0083] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
