[0037] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Reference Figure 1 , Figure 2 The side brush assembly 10 proposed in the embodiment of the utility model includes a base 100 and a blocking structure 200. The base 100 is used to assemble other accessories of the floor brush assembly. The base 100 has a bottom 111 and a top 121. The bottom 111 faces the surface to be cleaned, and the top 121 faces the shell of the cleaning device connected to the floor brush assembly.

[0040] A mounting bracket 140 is provided inside the base 100, and the mounting bracket 140 is provided with a plurality of mounting feet 141. The plurality of mounting feet 141 are arranged at intervals around the circumference of the mounting bracket 140, and the plurality of mounting feet 141 extend outside the base 100. Each mounting foot 141 is provided with bristles 142, and the bristles 142 can be made of nylon material.

[0041] A blocking structure 200 is provided on the base, and the blocking structure 200 is arranged circumferentially along the rotation center of the side brush assembly 10. When the side brush assembly 10 rotates, the blocking structure 200 can block flexible objects such as hair to prevent the flexible objects from being entangled in the transmission assembly connected to the side brush assembly 10.

[0042] When the side brush assembly 10 with the above structure rotates, the bristles 142 of the side brush assembly 10 rotate accordingly and clean the ground. When the bristles 142 clean flexible objects such as hair, some of the flexible objects such as hair will move and entangle in the direction of the bristles 142, and move upward along the bristles 142 as the side brush assembly 10 rotates. When the flexible objects such as hair move upward to the blocking structure 200, they are intercepted by the blocking structure 200. The flexible objects such as hair stay at the blocking structure 200 and cannot move upward any further. Therefore, the flexible objects such as hair cannot enter the transmission shaft 330 area of ​​the side brush assembly 10, cannot entangle the transmission shaft 330 of the side brush assembly 10, and cannot enter the speed reduction mechanism 320 of the side brush assembly 10, thereby avoiding overloading or jamming of the speed reduction mechanism 320, so as to ensure the normal cleaning operation of the cleaning equipment, avoid rotation failure of the side brush assembly 10, and improve the service life of the side brush assembly 10.

[0043] Reference Figure 1 , Figure 2In some embodiments, the blocking structure 200 is disposed on the end surface of the base 100 opposite to the housing of the cleaning device, and is extended along the axial direction of the side brush assembly 10. In other words, the blocking structure 200 is disposed on the top 121 of the base 100, and one end of the blocking structure 200 is close to the housing of the cleaning device. Thus, the blocking structure 200 is disposed on the path of flexible objects such as hair entering the transmission shaft 330 area. Before entering the transmission shaft 330 area, the blocking structure 200 intercepts the flexible objects such as hair, thereby blocking the path of the flexible objects such as hair along the bristles 142 to the transmission shaft 330 area. Therefore, the flexible objects such as hair cannot enter the transmission shaft 330 area, cannot be entangled with the transmission shaft 330 of the side brush assembly 10, and will not enter the speed reduction mechanism 320 of the side brush assembly 10, thereby avoiding overloading or jamming of the speed reduction mechanism 320, so as to ensure the normal cleaning operation of the cleaning device, avoid causing rotation failure of the side brush assembly 10, and improve the service life of the side brush assembly 10.

[0044] It is understandable that the blocking structure 200 may also be disposed on an edge of the base 100 close to the top 121 , which is not limited herein.

[0045] It should be noted that the transmission assembly connected to the side brush assembly 10 includes a transmission shaft 330 and a speed reduction mechanism 320 .

[0046] Reference Figure 1 , Figure 2 , Figure 3 In some embodiments, the blocking structure 200 includes a connecting portion 210 and a hook portion 220, wherein one end of the connecting portion 210 is connected to the base 100 and is extended in a direction away from the base 100, and the hook portion 220 is provided at one end of the connecting portion 210 away from the base 100 and extends in a direction away from the rotation center of the side brush assembly 10. When the side brush assembly 10 rotates, the bristles 142 of the side brush assembly 10 rotate accordingly and clean the ground. When the bristles 142 clean flexible objects such as hair, some of the flexible objects such as hair will move toward the direction of the bristles 142 and entangle with them, and move upward along the bristles 142 as the side brush assembly 10 rotates. When the flexible objects such as hair move upward to the blocking structure 200, they are intercepted by the hook 220 and entangled in the connecting portion 210 and the hook 220. The flexible objects such as hair stay at the blocking structure 200 and no longer move upward. Therefore, the flexible objects such as hair cannot enter the transmission shaft 330 area, cannot entangle the transmission shaft 330 of the side brush assembly 10, and will not enter the speed reduction mechanism 320 of the side brush assembly 10, thereby avoiding overloading or jamming of the speed reduction mechanism 320, so as to ensure the normal cleaning operation of the cleaning equipment, avoid rotation failure of the side brush assembly 10, and improve the service life of the side brush assembly 10.

[0047] It should be noted that the blocking structure 200 may also adopt other structural types. For example, in one embodiment, a plurality of grooves are arranged on the side of the blocking structure 200 away from the rotation center of the side brush assembly 10. The grooves are arranged in a direction perpendicular to the axis of the side brush assembly 10, and the plurality of grooves are arranged at intervals along the axis direction of the side brush assembly 10. The plurality of grooves are equivalent to a plurality of hooks 220. When the hair or other flexible objects move upward along the blocking structure 200, the plurality of grooves play a step-by-step interception role for the hair or other flexible objects, thereby effectively intercepting the hair or other flexible objects. In another embodiment, a sticky layer is arranged on the side of the blocking structure 200 away from the rotation center of the side brush assembly 10. The sticky layer can also achieve the purpose of intercepting the hair or other flexible objects by bonding the hair or other flexible objects that move to the blocking structure 200. In this embodiment, the sticky layer can be an adhesive layer, Velcro, etc.

[0048] Reference Figure 1 , Figure 2 , Figure 3 In some embodiments, the blocking structure 200 includes a connecting portion 210 and a hook portion 220. Reinforcing ribs 230 are provided on both sides of the connecting portion 210. The reinforcing ribs 230 are connected to the connecting portion 210 and are extended along the circumference of the base 100. By providing reinforcing ribs 230 on both sides of the connecting portion 210, the strength of the blocking structure 200 can be increased, and the interception area of ​​the blocking structure 200 can be increased, thereby improving the probability of intercepting flexible objects such as hair, thereby reducing the probability of flexible objects such as hair entering the transmission shaft 330 area.

[0049] Reference Figure 1 , Figure 2 In some embodiments, the mounting bracket 140 is provided with three mounting legs 141, and the three mounting legs 141 are evenly spaced around the circumference of the mounting bracket 140, and each mounting leg 141 is provided with bristles 142, and three blocking structures 200 are provided, and the three blocking structures 200 are arranged one by one corresponding to the three mounting legs 141, and are spaced along the circumference of the base 100. That is, referring to Figure 1 The blocking structure 200 is disposed on the base 100 and is close to the connection between the corresponding mounting foot 141 and the base 100. As a result, when the side brush assembly 10 rotates, the bristles 142 of the side brush assembly 10 rotate accordingly and clean the ground. When the bristles 142 clean flexible objects such as hair, the flexible objects such as hair move upward along the bristles 142 to the connection between the mounting foot 141 and the base 100. When the path for the flexible objects such as hair to move upward is about to become wider, they are intercepted by the blocking structure 200, thereby further improving the interception efficiency.

[0050] It should be noted that the number of mounting feet 141 can be set to two or more according to specific needs, and the number of blocking structures 200 can be set according to the number of mounting feet 141 or according to actual needs, which is not limited here.

[0051] Reference Figure 2 In some embodiments, the base 100 includes a base 110 and an upper cover 120, the upper cover 120 and the base 110 can be fixedly connected by ultrasonic welding or fastener connection, a mounting cavity 130 is formed between the base 110 and the upper cover 120, the mounting bracket 140 is arranged in the mounting cavity 130, the base 110 is provided with a plurality of avoidance gaps 112, the avoidance gaps 112 are connected to the mounting cavity, and the avoidance gaps 112 are provided for the mounting legs 141 to pass through. Thus, the assembly and positioning of the mounting bracket 140 on the base 100 can be facilitated, and the assembly difficulty of the mounting bracket 140 can be reduced.

[0052] In some embodiments, the blocking structure 200 can be disposed on the base 110 or on the upper cover 120, and the blocking structure 200 and the base 100 can be separate structures. Specifically, the base 110, the upper cover 120 and the blocking structure 200 are all separate parts, and the base 110, the upper cover 120 and the blocking structure 200 are detachably connected through a connecting structure or fasteners, or fixedly connected by ultrasonic welding.

[0053] It should be noted that the blocking structure 200 and the base 100 can also be an integral structure by injection molding. In addition, the base 110 and the upper cover 120 can also be an integral structure, thereby reducing the number of components of the side brush assembly 10 and reducing the assembly process. The base 110 and the upper cover 120 are an integral structure, which can be fixedly connected by ultrasonic welding or integrally molded by injection molding.

[0054] Reference Figure 2 In some embodiments, three connectors 113 are provided on the base 110, and the three connectors 113 extend along the axial direction of the side brush assembly 10 and are evenly spaced along the circumference of the rotation center of the side brush assembly 10. Three avoidance holes 122 are correspondingly provided on the upper cover 120, and the three avoidance holes 122 are evenly spaced along the circumference of the rotation center of the side brush assembly 10, and the connectors 113 are inserted into the corresponding avoidance holes 122. When assembling the base 110 and the upper cover 120, the connectors 113 can be inserted along the corresponding avoidance holes 122, which is convenient and quick, and by providing three connectors 113 and three corresponding avoidance holes 122, blind insertion of the base 110 and the upper cover 120 during assembly can be achieved.

[0055] Reference Figure 2A hook 114 is provided on the connector 113, and a buckle slot 340 is provided at a corresponding position of the transmission shaft 330 of the driving mechanism 300 of the side brush assembly 10. When the side brush assembly 10 is connected to the driving mechanism 300, the hook 114 is clamped in the buckle slot 340, and the driving mechanism 300 drives the side brush assembly 10 to rotate through the cooperation of the hook 114 and the buckle slot 340. In addition, the side brush assembly 10 is easily disassembled and installed through the cooperation of the hook 114 and the buckle slot 340.

[0056] It should be noted that the number of the connectors 113 and the avoidance holes 122 can be two or more, which will not be described in detail herein.

[0057] Reference Figure 1 In some embodiments, the mounting foot 141 is configured as a rubber strip, and the mounting bracket 140 can move along the axial direction of the side brush assembly 10, and the mounting foot 141 abuts against the bottom edge of the avoidance gap 112. When the side brush assembly 10 is assembled to the cleaning device, the bottom edge of the avoidance gap 112 abuts against the lower part of the mounting foot 141, and the mounting foot 141 is in a deformed state, so that the ends of the bristles 142 are tilted upward and do not contact the ground. When the cleaning device is used, the driving mechanism 300 of the side brush assembly 10 drives the mounting bracket 140 to move upward along the axial direction of the side brush assembly 10, and the deformation of the mounting foot 141 is restored, so that the ends of the bristles 142 move downward to contact the ground, thereby realizing the sweeping function when the side brush assembly 10 rotates.

[0058] Reference Figure 1 , Figure 2 In some embodiments, the mounting bracket 140 is provided with a connecting member 143, the connecting member 143 is provided with a threaded hole 144, and the connecting shaft 350 of the side brush assembly 10 is used for threaded connection with the threaded hole 144. Since the connecting shaft 350 is threadedly connected with the threaded hole 144 on the connecting member 143, the mounting bracket 140 can be raised or lowered by the forward and reverse rotation of the driving mechanism 300, thereby causing the bristles 142 to be lowered or raised.

[0059] Specifically, when the cleaning equipment starts cleaning, the driving mechanism 300 drives the mounting bracket 140 to move upward along the axial direction of the side brush assembly 10 through the connecting shaft 350, and the mounting foot 141 is restored. Under the elastic action of the mounting foot 141, the end of the bristle 142 moves downward to contact the ground to realize the sweeping function; after cleaning, the driving mechanism 300 drives the mounting bracket 140 to move downward along the axial direction of the side brush assembly 10 through the connecting shaft 350, and the bottom edge of the avoidance notch 112 abuts against the lower part of the mounting foot 141. The mounting foot 141 is in a deformed state, causing the end of the bristle 142 to curl upward, and the bristle 142 is separated from the ground.

[0060] It is understandable that the connecting member 143 may be a nut, and the nut may be made of the same material as the mounting bracket 140 , and the nut may be fixedly connected to the mounting bracket 140 by welding or integral molding.

[0061] Reference Figure 1 , Figure 2 In some embodiments, a rib 145 is provided on the side of the mounting foot 141 away from the axis of the side brush assembly 10. The rib 145 is used to cooperate with the damping member on the housing of the cleaning device to change the current of the motor 310 of the cleaning device, thereby detecting the change in the current of the motor 310 and locating the position of the bristles 142. When the side brush assembly 10 stops rotating, the bristles 142 can avoid the downward sensor position of the cleaning device and the bristles 142 will not stop directly forward.

[0062] Reference Figure 4 The cleaning device proposed in the embodiment of the utility model includes a motor 310, a speed reduction mechanism 320 connected to the motor 310, and a side brush assembly 10 proposed in any of the above embodiments, and the side brush assembly 10 is connected to the speed reduction mechanism 320 through a transmission shaft 330. When the side brush assembly 10 rotates, the hair and other flexible objects wrapped around the bristles 142 of the side brush assembly 10 move upward with the rotation of the side brush assembly 10. When the hair and other flexible objects move to the blocking structure 200, they are intercepted by the blocking structure 200, and the hair and other flexible objects no longer move upward, so they cannot wrap around the transmission shaft 330 of the side brush assembly 10, and they will not enter the speed reduction mechanism 320 of the side brush assembly 10, thereby avoiding overloading or jamming of the speed reduction mechanism 320, so as to ensure the normal cleaning operation of the cleaning device, avoid causing rotation failure of the side brush assembly 10, and improve the service life of the side brush assembly 10.

[0063] It is understandable that the cleaning device 10 of the present invention may be a vacuum cleaner, a sweeping robot, a floor scrubber, etc.

[0064] In some embodiments, the side brush assembly 10 is detachably connected to the transmission shaft 330. When the side brush assembly 10 is disassembled, the hair and other flexible objects are hung on the blocking structure 200, and the hair and other flexible objects can be disassembled together with the side brush assembly 10. Therefore, after the cleaning operation of the cleaning device is completed, the user only needs to unplug the side brush assembly 10, and the hair and other flexible objects will be hung on the blocking structure 200 and removed together, so that the hair and other flexible objects can be cleaned out, thereby reducing the frequency and time of cleaning for users, improving user experience, and improving product competitiveness.

[0065] Reference Figures 5 to 8 , the functions of the cleaning device of the present application are specifically described below by taking the cleaning operation of a cleaning device of a specific embodiment as an example.

[0066] In this embodiment, the motor 310 serving as the driving mechanism 300 of the side brush assembly 10 is connected to the side brush assembly 10 through the reduction mechanism 320 to drive the side brush assembly 10 to rotate. Specifically, the connecting shaft 360 of the side brush assembly 10 is rotatably arranged in the housing of the reduction mechanism 320 through a one-way bearing 350. A damping ring 370 is fixedly connected to one end of the connecting shaft 360. A damping cover 380 is provided on the housing of the reduction mechanism 320. The damping ring 370 and the damping cover 380 can be engaged or separated. A thread is provided on the other end of the connecting shaft 360. A connecting piece 143 is provided on the side brush assembly 10. A threaded hole 144 is provided on the connecting piece 143. The connecting shaft 360 can be threadedly connected to the threaded hole 144.

[0067] When the cleaning equipment starts cleaning, the motor 310 rotates forward, driving the side brush assembly 10 to rotate through the reduction mechanism 320, and the damping cover 380 and the damping ring 370 are engaged, and the connecting shaft 360 cannot rotate with the side brush assembly 10. At this time, the connecting end of the connecting shaft 360 and the connecting member 143 is screwed into the threaded hole 144 of the connecting member 143, and the connecting member 143 rises, driving the mounting bracket 140 to move upward along the axial direction of the side brush assembly 10, and the mounting foot 141 is restored. Under the elastic action of the mounting foot 141, the end of the bristle 142 moves downward to contact the ground, and the damping cover 380 and the damping ring 370 are disengaged and no longer engaged.

[0068] The motor 310 continues to rotate forward, the side brush assembly 10 continues to rotate, and the bristles 142 of the side brush assembly 10 rotate accordingly and clean the ground. When the bristles 142 clean flexible objects such as hair, some of the flexible objects such as hair will move toward the direction of the bristles 142 and entangle with them, and move upward along the bristles 142 as the side brush assembly 10 rotates. When the flexible objects such as hair move upward to the blocking structure 200, they are intercepted by the hook 220 and entangled in the connecting portion 210 and the hook 220. The flexible objects such as hair stay at the blocking structure 200 and no longer move upward. Therefore, the flexible objects such as hair cannot enter the transmission shaft 330 area, cannot entangle the transmission shaft 330 of the side brush assembly 10, and will not enter the reduction mechanism 320 of the side brush assembly 10, thereby avoiding overloading or jamming of the reduction mechanism 320 to ensure the normal cleaning operation of the cleaning equipment.

[0069] After cleaning, the motor 310 reverses. Since the connecting shaft 360 is arranged in the housing of the reduction mechanism 320 through the one-way bearing 350, when the motor 310 reverses, the one-way bearing 350 locks the connecting shaft 360, and the connecting shaft 360 does not rotate. The side brush assembly 10 rotates, and the connecting shaft 360 gradually withdraws from the threaded hole 144 of the connecting member 143, driving the connecting member 143 to descend, thereby driving the mounting bracket 140 to move downward along the axial direction of the side brush assembly 10, avoiding the bottom edge of the notch 112 to abut against the lower part of the mounting foot 141, and the mounting foot 141 is in a deformed state, causing the ends of the bristles 142 to curl upward, and the bristles 142 to separate from the ground to retract the bristles 142.

[0070] When it is necessary to clean the soft objects such as hair on the side brush assembly 10, the side brush assembly 10 can be unplugged from the driving mechanism 300. Therefore, the frequency and time of cleaning by the user can be reduced, the user experience is improved, and the product competitiveness is improved.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
