Floor brush assembly and cleaning device

Abstract

The application provides a floor brush assembly and a cleaning device, and relates to the technical field of household appliances, and aims to solve the technical problem that hair is easily entangled on the axle of the walking wheel, which increases the rotating resistance of the axle. In the floor brush assembly, a blocking structure is arranged at the gap between the two ends of the two walking wheels and the two mounting holes. The blocking structure is arranged around the outer periphery of the axle coaxially connecting the two walking wheels and extends along the axial direction of the axle to close the gap between the end surface of the mounting hole and the corresponding walking wheel. In this way, when the device is working, the hair, fiber rope and other entanglements on the ground are blocked outside the blocking structure and are not easy to enter the position where the axle and the walking wheel rotate at high speed, so as to avoid being entangled on the axle or between the axle and the walking wheel, thereby avoiding the problems of increased axle resistance and jamming of the walking wheel, improving the working reliability and stability of the device, and prolonging the service life of the device.

Description

Technical Field

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

[0002] Floor scrubbers, vacuum cleaners, and other cleaning equipment are widely used in homes and commercial environments to clean dust, debris, hair, and other dirt from floors. They achieve their cleaning function by using a motor to drive a rotating brush and coordinating with airflow to achieve the same effect, and have become an important part of modern cleaning tools.

[0003] In related technologies, the floor brush assembly of such cleaning equipment typically includes a floor brush body, a walking mechanism, and a drive mechanism. The walking mechanism consists of an axle located at the rear of the floor brush body, two large-sized walking wheels coaxially connected to both ends of the axle, and a small wheel assembly located at the front of the floor brush. The floor brush body has mounting holes to accommodate the axle. A notch is provided at the bottom of the floor brush body corresponding to the positions of the walking wheels, exposing the walking wheels to the outside to enable smooth movement on the ground.

[0004] However, in the relevant technology, there is a gap between the end face of each walking wheel and the mounting hole on the brush body. During the cleaning process, hair on the ground is easily carried into the gap by the rotating walking wheel. The hair is easily wrapped around the wheel axle. As the amount of hair wrapped around increases, the rotational resistance of the wheel axle increases, which can easily lead to the problem of the walking wheel getting stuck. Utility Model Content

[0005] In view of the above problems, this application provides a floor brush assembly and cleaning device, which aims to prevent hair and other entangled objects from entering the axle with the walking wheel and getting tangled on the axle, thereby improving the anti-tangling performance of the device and improving product reliability and stability.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a floor brush assembly, including a floor brush body and a walking mechanism. The walking mechanism includes two walking wheels and axles. The floor brush body has a mounting hole for accommodating the axles. The axles pass through the mounting hole. The two walking wheels are located at the axial ends of the mounting hole and are coaxially mounted on the corresponding ends of the axles. The end faces of the mounting holes at both ends have gaps with the corresponding axles. The bottom of the floor brush body has clearance notches at positions corresponding to the two walking wheels. Part of the structure of the walking wheels is exposed outside the bottom of the floor brush body through the clearance notches.

[0008] The brush body has a shielding structure at each position corresponding to the gap. The shielding structure surrounds the outer periphery of the axle and extends along the axial direction of the axle to close the gap between the end face of the mounting hole and the corresponding walking wheel.

[0009] In this embodiment, a shielding structure is provided at the gap between the two end faces of the two traveling wheels and the two mounting holes. The shielding structure surrounds the outer periphery of the axle that coaxially connects the two traveling wheels and extends along the axial direction of the axle to close the gap between the end face of the mounting hole and the corresponding traveling wheel. In this way, when the equipment is cleaning, hair, fiber ropes and other entangled objects on the ground are blocked outside the shielding structure and are less likely to enter the position where the axle and traveling wheels are rotating at high speed. This prevents them from getting tangled on the axle or between the axle and the traveling wheels, avoiding the problems of increased axle resistance and traveling wheel jamming. This improves the reliability and stability of the equipment and extends its service life.

[0010] In some alternative embodiments, each of the shielding structures is located on the outer periphery of the mounting hole.

[0011] In this way, hair, fiber ropes and other entangled materials are blocked outside the mounting hole by the shielding structure, preventing hair and other entangled materials from entering the mounting hole and wrapping around the axle, thereby improving the shielding effect, reducing the rotational resistance of the axle, and improving the reliability and stability of the product.

[0012] In some alternative embodiments, each of the walking wheels has a relief recess at one end facing the shielding structure, and the edge of the shielding structure facing the walking wheel has a flange extending away from the central area. At least the flange is located in the relief recess and is sealed to the inner peripheral wall of the relief recess, and the other end of the shielding structure is in direct contact with the end face of the corresponding end of the mounting hole.

[0013] This further enhances the sealing effect of the shielding structure and its corresponding gaps, further preventing hair and other entangled objects from getting tangled on the axle.

[0014] In some alternative embodiments, the shielding structure has a recessed accumulation area along its outer peripheral wall, which is configured to gather up the entanglement blocked from the outside of the shielding structure when the floor brush assembly cleans the floor.

[0015] In this way, hair and other tangled objects blocked outside the shielding structure can be effectively collected by the accumulation area, preventing them from spreading randomly or being rolled back into the surrounding area. On the one hand, this reduces the probability of tangled objects coming into contact with and entering the gaps between the axle and the wheels; on the other hand, it facilitates the centralized cleaning of tangled objects accumulated on the shielding structure, thereby improving the anti-tangling properties and maintenance convenience of the equipment.

[0016] In some alternative embodiments, the contours of each of the shielding structures are curved along the axial direction of the wheel axle;

[0017] Wherein, along the radial direction of the wheel axle, the radial dimensions at both ends of each of the shielding structures are greater than the cross-sectional dimensions of the central region of the shielding structure, and the central region of the shielding structure along the axial direction of the wheel axle forms the accumulation area.

[0018] In this way, hair and other tangled objects blocked outside the shielding structure can be effectively guided to slide along the contour of the shielding structure to the accumulation area in the middle and remain there. This prevents the tangled objects from entering the gap between the wheel and axle and accumulating on the wheel and axle or being rolled into the wheels again, significantly improving the reliability of anti-tangling and the convenience of cleaning operations.

[0019] In some alternative embodiments, the brush body includes a brush base and a brush cover, the brush cover being configured to be mounted on the brush base, and the shielding structure being provided on at least one of the brush base and the brush cover.

[0020] This increases the modularity of the floor brush components, thereby reducing the overall manufacturing cost and assembly complexity.

[0021] In some optional embodiments, the bottom shell of the floor brush has a first flange that is open toward the side of the floor brush cover and recessed toward the bottom side of the floor brush bottom shell at the position corresponding to each of the gaps; the floor brush cover has a second flange that is open toward the side of the floor brush bottom shell and recessed toward the side away from the floor brush bottom shell at the position corresponding to each of the gaps.

[0022] When the floor brush cover is assembled onto the floor brush base, each of the first flanges and its corresponding second flanges are aligned to form the shielding structure.

[0023] In this way, the first and second flanges, which are respectively located on the bottom shell of the floor brush and the cover of the floor brush, are connected to each other after assembly to form a complete shielding structure. This reduces the manufacturing difficulty of the shielding structure and the installation difficulty between the wheel axle and the shielding structure. At the same time, it ensures the uniformity and consistency of the gap control between the shielding structure and the wheel axle, thereby significantly enhancing the overall effect of preventing hair entanglement and the product yield.

[0024] In some alternative embodiments, each of the first flanges is integrally formed with the bottom shell of the floor brush; and / or,

[0025] Each of the second flanges is an integral structure with the floor brush cover.

[0026] This can further reduce assembly processes, thereby lowering assembly costs and improving assembly efficiency.

[0027] In some optional embodiments, at least two first oil reservoirs, arranged circumferentially at intervals, are provided on the outer peripheral walls of the connections between the axial ends of the axle and the two traveling wheels. These first oil reservoirs are used to store lubricating grease; and / or,

[0028] Each of the aforementioned wheels has a mounting hole that matches the wheel axle. On the inner peripheral wall of the mounting hole, at least two second oil reservoirs are provided, which are arranged at intervals along the circumference of the mounting hole. The second oil reservoirs are used to store lubricating grease.

[0029] In this way, the grease stored in the first and / or second oil reservoirs can lubricate the wheel axle and the traveling wheel, reducing wear and abnormal noise, thereby extending the service life of the parts and improving the user experience.

[0030] In some optional embodiments, when the outer peripheral wall of the axle has the first oil reservoir, the length direction of the first oil reservoir extends along the axial direction of the axle; and / or,

[0031] When the inner peripheral wall of the assembly hole has the second oil reservoir, the length direction of the second oil reservoir extends along the axial direction of the assembly hole.

[0032] This increases the volume of the first and / or second oil reservoirs, while also increasing the lubrication coverage area, thereby reducing wear between the axle and the traveling wheel and abnormal noise caused by friction, further extending the service life of components and improving the user experience.

[0033] A second aspect of this application provides a cleaning device, including a floor brush assembly as provided in the first aspect.

[0034] The cleaning equipment provided in this application embodiment has the same beneficial effects as the floor brush assembly provided in the above embodiment, and will not be described again here.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] This application provides a cleaning device, including but not limited to floor scrubbers, vacuum cleaners, etc., for cleaning dirt such as dust, debris and hair on the ground. It achieves the cleaning function by driving a roller brush to rotate with airflow.

[0058] Please refer to Figure 1 and Figure 2 As shown, the cleaning equipment includes a floor brush assembly 10 and a main unit connected to the floor brush assembly 10. The floor brush assembly 10 includes a floor brush body 100, a walking mechanism 200, and a drive mechanism. The walking mechanism 200 consists of a wheel axle 220 located at the rear of the floor brush body 100, two large-sized walking wheels 210 coaxially connected to both ends of the wheel axle 220, and a small wheel set located at the front of the floor brush. The floor brush body 100 has mounting holes 110 for accommodating the wheel axle 220. The bottom of the floor brush body 100 has notches corresponding to the positions of the walking wheels 210, exposing part of the walking wheels 210 to the outside to achieve smooth movement on the ground.

[0059] Because there is a gap between the two large-sized walking wheels 210 at the rear and the end face of the mounting holes 110 on the brush body 100, in order to prevent the walking wheels 210 from rotating smoothly and getting stuck, during the cleaning process, hair on the ground is easily carried into this gap by the rotating large-sized walking wheels 210. The hair is easily wrapped around the wheel axle 220. As the amount of hair wrapped around increases, the rotational resistance of the wheel axle 220 increases, which can easily lead to the problem of the walking wheels 210 getting stuck.

[0060] To overcome the defects of the above structure, this application provides an improved floor brush assembly 10, which can block hair, fiber ropes and other entangled objects on the ground from entering the gap when the equipment is cleaning. This makes it difficult for hair to enter the high-speed rotating position of the axle 220 and the traveling wheel 210, and thus it is less likely to get tangled on the axle 220 or between the axle 220 and the traveling wheel 210. This avoids the problem of increased resistance of the axle 220 and jamming of the traveling wheel 210, thereby improving the reliability and stability of the equipment and extending its service life.

[0061] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0062] Please refer to Figures 1 to 3 , Figure 5 As shown, the floor brush assembly 10 provided in this application embodiment includes a floor brush body 100 and a walking mechanism 200. The walking mechanism 200 includes two walking wheels 210 and a wheel axle 220. Since the two large walking wheels 210 at the rear end of the floor brush assembly 10 are prone to carrying hair and other debris when walking, the improvements in this application include, but are not limited to, improving the structure of the two large walking wheels 210 at the rear end. Therefore, the walking wheels 210 mentioned in this document refer to the two large walking wheels 210 located at the rear end of the floor brush assembly 10. Of course, the improvements in this application are also applicable to the small walking wheels 210 at the front end.

[0063] like Figure 4 and Figure 5 As shown, the floor brush body 100 has a mounting hole 110 inside to accommodate a wheel axle 220. The wheel axle 220 passes through the mounting hole 110. Two traveling wheels 210 are located at the two axial ends of the mounting hole 110 and are coaxially mounted on the corresponding ends of the wheel axle 220. There is a gap between the end faces of the mounting hole 110 and the corresponding wheel axle 220. There is a clearance notch at the bottom of the floor brush body 100 corresponding to the two traveling wheels 210. Part of the structure of the traveling wheel 210 is exposed outside the bottom of the floor brush body 100 through its corresponding clearance notch so that the traveling wheel 210 can roll and contact the ground, thereby walking on the ground.

[0064] Please continue to refer to Figure 4 As shown, the brush body 100 has a shielding structure 120 at each position corresponding to the gap. The shielding structure 120 surrounds the outer periphery of the axle 220 and extends along the axial direction of the axle 220 to close the gap between the end face of the mounting hole 110 and the corresponding walking wheel 210.

[0065] In this embodiment, a shielding structure 120 is provided at the gap between the two end faces of the two traveling wheels 210 and the two mounting holes 110. The shielding structure 120 surrounds the outer periphery of the axle 220 that coaxially connects the two traveling wheels 210 and extends along the axial direction of the axle 220 to close the gap between the end face of the mounting hole 110 and the corresponding traveling wheel 210. In this way, when the equipment is cleaning, hair, fiber ropes and other entangled objects on the ground are blocked outside the shielding structure 120 and are not likely to enter the position where the axle 220 and the traveling wheels 210 are rotating at high speed. This prevents them from getting tangled on the axle 220 or between the axle 220 and the traveling wheels 210, thus avoiding the problem of increased resistance of the axle 220 and jamming of the traveling wheels 210. This improves the reliability and stability of the equipment and extends its service life.

[0066] In other words, the shielding structure 120 blocks and seals the gap between the end faces of the walking wheel 210 and the corresponding ends of the mounting hole 110, so that the exposed wheel axle 220 is completely isolated from the outer peripheral structure through the shielding structure 120. In this way, the hair carried by the walking wheel 210 can be blocked outside the shielding structure 120, and some hair and other entangled objects will be wrapped around the outer peripheral wall of the shielding structure 120. However, the hair and other entangled objects wrapped around the outer peripheral wall of the shielding structure 120 will not affect the rotation of the walking wheel 210, nor will it increase the load on the drive motor that drives the wheel axle 220. In addition, the hair wrapped around the outer peripheral wall of the shielding structure 120 achieves the purpose of collecting hair and other entangled objects, thereby avoiding problems such as hair and other entangled objects flying around randomly. Users can then collect and dispose of them in a centralized manner, thereby improving the user experience.

[0067] In addition, such as Figure 4 and Figure 5 As shown, each shielding structure 120 is located on the outer periphery of the mounting hole 110. In this way, hair, fiber rope and other entangled objects are shielded outside the mounting hole 110 by the shielding structure 120, preventing hair and other entangled objects from entering the mounting hole 110 and wrapping around the axle 220, thereby improving the shielding effect, reducing the rotational resistance of the axle 220, and improving the reliability and stability of the product.

[0068] Please continue to refer to Figure 4 As shown, each of the walking wheels 210 has a relief recess 211 at one end facing the shielding structure 120, and the edge of the shielding structure 120 facing the walking wheel 210 has a flange 121 extending away from the central area. At least the flange 121 is located in the relief recess 211 and is sealed to the inner peripheral wall of the relief recess 211. The other end of the shielding structure 120 is in direct contact with the end face of the corresponding end of the mounting hole 110.

[0069] For example, the shielding structure 120 can be integrally formed with the end face corresponding to the mounting hole 110 by bonding, welding, or integral molding. In this way, there will be no assembly gap between the shielding structure 120 and the end face corresponding to the mounting hole 110, thereby preventing hair from entering the assembly gap. In addition, the end of the shielding structure 120 facing the corresponding wheel 210 is provided with an outward flange 121. At least the flange 121 is located in the avoidance recess 211 of the wheel 210, and the outer peripheral wall of the flange 121 abuts against the inner peripheral wall of the avoidance recess 211. Improving the sealing effect of the shielding structure 120 and its corresponding gaps creates a better barrier against hair, effectively preventing hair and other entangled objects from entering the gap between the wheel axle 220 and the walking wheel 210 from both ends of the shielding structure 120. This further enhances the shielding effect of the shielding structure 120, preventing hair and other entangled objects from getting tangled on the wheel axle 220, effectively preventing an increase in the rotational resistance of the wheel axle 220, avoiding an increase in the load on the drive motor that drives the wheel axle 220, and further improving the reliability, stability and service life of the product.

[0070] Please continue to refer to Figure 4 The shielding structure 120 has a recessed accumulation area 122 on its outer peripheral wall. When the floor brush assembly 10 cleans the floor, the accumulation area 122 is configured to gather the entanglement that is blocked from the outside of the shielding structure 120.

[0071] In this way, hair and other tangled objects blocked outside the shielding structure 120 can be effectively collected by the accumulation area 122, preventing hair and other tangled objects from spreading randomly or being rolled back into the surrounding area. On the one hand, this reduces the probability of tangled objects coming into contact with and entering the gaps between the axle 220 and the walking wheel 210; on the other hand, it facilitates the centralized cleaning of tangled objects accumulated on the shielding structure 120, thereby improving the anti-tangling performance and maintenance convenience of the equipment.

[0072] In some embodiments, the contours of each shielding structure 120 are curved along the axial direction of the wheel axle 220; wherein, along the radial direction of the wheel axle 220, the radial dimensions at both ends of each shielding structure 120 are greater than the cross-sectional dimensions of the central region of the shielding structure 120, and the central region of the shielding structure 120 along the axial direction of the wheel axle 220 is formed as an accumulation area 122. In this way, hair and other entangled objects blocked outside the shielding structure 120 can be effectively guided to slide along the contour of the shielding structure 120 to the central accumulation area 122 and remain in the accumulation area 122, thereby preventing the entangled objects from entering the gap of the wheel axle 220 and entangled and accumulated on the wheel axle 220 or being rolled up again by the traveling wheel 210, which significantly improves the reliability of anti-entanglement and the convenience of cleaning operations.

[0073] Please refer to Figure 5As shown, the floor brush body 100 includes a floor brush bottom shell 101, a floor brush cover 102, and a floor brush top cover 103. The floor brush cover 102 is configured to be mounted on the floor brush bottom shell 101, and the two together form a cavity for accommodating structures such as roller brushes. The floor brush top cover 103 is mounted on the floor brush cover 102. At least one of the floor brush bottom shell 101 and the floor brush cover 102 is provided with a shielding structure 120. For example, the shielding structure 120 can be integrated with at least one of the floor brush bottom shell 101 and the floor brush cover 102. This improves the modularity of the floor brush assembly 10, thereby reducing the manufacturing cost and assembly complexity of the whole machine.

[0074] Please continue to refer to Figure 5 As shown, at positions corresponding to each gap on the floor brush base 101, there is a first flange 1011 that is open towards the side of the floor brush cover 102 and recessed towards the bottom side of the floor brush base 101; at positions corresponding to each gap on the floor brush cover 102, there is a second flange 1021 that is open towards the side of the floor brush base 101 and recessed away from the side of the floor brush base 101; when the floor brush cover 102 is assembled onto the floor brush base 101, each first flange 1011 and its corresponding second flange 1021 are in contact. Together, they form a shielding structure 120. Thus, the first flange 1011 and the second flange 1021, which are respectively located on the bottom shell of the brush 101 and the brush cover 102, are connected to each other after assembly to form a complete shielding structure 120. This reduces the manufacturing difficulty of the shielding structure 120 and the installation difficulty between the wheel axle 220 and the shielding structure 120. At the same time, it ensures the uniformity and consistency of the gap control between the shielding structure 120 and the wheel axle 220, thereby significantly enhancing the overall effect of preventing hair entanglement and the product yield.

[0075] For example, the brush cover 102 and the brush base 101 are detachably connected to facilitate the installation of various components inside the brush assembly 10. In addition, when the brush cover 102 is installed on the brush base 101, the first flange 1011 directly abuts with the second flange 1021 to jointly form a shielding structure 120 without the need for other connecting structures, which simplifies the manufacturing process and reduces manufacturing costs.

[0076] In some embodiments, each of the first flanges 1011 is integrally formed with the floor brush base shell 101 through molding processes such as injection molding and casting; each of the second flanges 1021 is integrally formed with the floor brush cover 102 through molding processes such as injection molding and casting. In this way, the assembly process can be further reduced, thereby reducing assembly costs and improving assembly efficiency.

[0077] Please refer to Figure 6 , Figure 7 and Figure 8As shown, the wheel 210 has a mounting hole through which the axle 220 passes. The axle 220 is connected to the mounting hole by a key, which can be a common flat key, a wedge key, or a spline. In addition, the outer end face of the wheel 210 (i.e. the side visible to the user) is covered with a wheel cover 230. A decorative ring 240 is inlaid on the outer periphery of the wheel cover 230 to enhance the overall aesthetics of the wheel 210.

[0078] For example, the materials of the axle 220 and the wheel 210 include, but are not limited to, metal, plastic, etc.

[0079] In order to reduce the friction between the axle 220 and the traveling wheel 210 and improve the smoothness of the rotation of the traveling wheel 210, in the embodiments of this application, please refer to... Figure 7 , Figure 8 and Figure 9 As shown, at least two first oil reservoirs 221 are provided on the outer peripheral walls of the connection points between the two axial ends of the axle 220 and the two traveling wheels 210, arranged at intervals along the circumference. The first oil reservoirs 221 are used to store grease. And / or, each traveling wheel 210 has a mounting hole that matches the axle 220. At least two second oil reservoirs are provided on the inner peripheral walls of the mounting hole, arranged at intervals along the circumference of the mounting hole. The second oil reservoirs are used to store grease.

[0080] In other words, the first oil reservoir 221 may be provided only on the axle 220; or the second oil reservoir may be provided only on the inner wall of the mounting hole of the traveling wheel 210; or the first oil reservoir 221 may be provided on the axle 220, and the second oil reservoir may be provided on the inner wall of the mounting hole of the traveling wheel 210.

[0081] The first oil reservoir 221 and the second oil reservoir are both used to store grease. In this way, the grease stored in the first oil reservoir 221 and the second oil reservoir can lubricate the wheel axle 220 and the traveling wheel 210, reduce wear and abnormal noise caused by poor lubrication, thereby extending the service life of the parts and improving the user experience.

[0082] When the outer peripheral wall of the axle 220 has a first oil reservoir 221, the length direction of the first oil reservoir 221 extends along the axial direction of the axle 220 (e.g., Figure 7 and Figure 8 (As shown in the figure) When the inner peripheral wall of the mounting hole has a second oil reservoir, the length direction of the second oil reservoir extends along the axial direction of the mounting hole. In this way, the volume of the first oil reservoir 221 and / or the second oil reservoir can be increased, and the lubrication coverage area can be increased, thereby reducing the wear between the wheel axle 220 and the traveling wheel 210 and the abnormal noise caused by friction, further extending the service life of the parts and improving the user's experience.

[0083] like Figures 7 to 9 As shown, in a specific implementation, the axle 220 is provided with a first oil reservoir 221, and the walking mechanism 200 is installed on the brush body 100. Each first oil reservoir 221 is first filled with lubricating grease, and then the axle 220 is passed through the mounting hole of the walking wheel 210. The wheel cover 230 and the decorative ring 240 are pre-installed and then placed on the outer end of the walking wheel 210 to complete the installation of the walking wheel 210 and the axle 220. After that, the internal parts of the brush are assembled on the brush bottom shell 101, and the axle 220 is installed in the mounting hole 110. Then, the brush cover 102 and the brush top cover 103 are installed in sequence.
