Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and in particular to a floor brush assembly, cleaning equipment and a system. Background Art

[0002] In recent years, with the improvement of people's living standards, home cleaning has gradually entered an era of automation and intelligence. Cleaning equipment has emerged, such as sweeping robots and floor scrubbers. Floor scrubbers can free people from home cleaning work, effectively reduce people's workload in home cleaning, and alleviate people's fatigue during home cleaning.

[0003] In the related art, it is very easy for entangled objects, balls of thread and other thin linear garbage to appear in the working environment of the floor scrubber. Such garbage is very easy to entangle the cleaning parts of the cleaning device, which can easily affect the cleaning effect, hinder the normal operation of the floor brush assembly, and even burn out the motor. In order to solve this problem, the prior art cleans the cleaning parts by setting up additional cutting components, which can easily damage the implanted hair on the cleaning parts during the cleaning process, affecting the subsequent cleaning effect of the cleaning parts. Utility Model Content

[0004] The embodiments of the present application provide a floor brush assembly, a cleaning device and a system to solve the problem that entangled objects on the existing floor brush assembly are difficult to clean.

[0005] In a first aspect, the present application provides a floor brush assembly, comprising a housing, a cleaning member and a scraper assembly, wherein the housing comprises a receiving cavity. The cleaning member is disposed in the receiving cavity and is rotatably connected to the housing. The scraper assembly is connected to the housing, and a side of the scraper assembly facing the cleaning member is at least partially interference-fitted with the cleaning member. A side of the scraper assembly facing away from the cleaning member is provided with a plurality of cutting structures, and the cutting structures are at least used to cut windings located on the cleaning member.

[0006] The floor brush assembly in the embodiment of the present application is provided with a shell to provide an installation position for other parts of the floor brush assembly to improve the aesthetics of the cleaning assembly. And the shell can protect the parts located in the shell to prevent the parts in the shell from falling dust. By providing a receiving cavity on the shell, a receiving space is provided for the cleaning member. By providing a scraper assembly, and at least partially interfering with the cleaning member on one side of the scraper assembly facing the cleaning member, the scraper assembly can pick up the windings wound on the cleaning member, and the windings can be prevented from being wound on the cleaning member. By providing a cutting structure on the side of the scraper assembly facing away from the cleaning member, the scraper assembly can pick up and cut the windings wound on the cleaning member, so that the cut windings can be separated from the cleaning member, so that the cut windings can be sucked from the suction port of the floor brush assembly into the sewage tank connected to the cleaning member. Based on the prior art, the additional cutting assembly cleans the cleaning member, which is easy to damage the implanted hair on the cleaning member during the cleaning process, thereby affecting the subsequent cleaning effect of the cleaning member. Therefore, in the present application, the cutting structure is arranged on the side of the scraper assembly away from the cleaning member, which can effectively prevent the cutting structure from damaging the bristles of the cleaning member while ensuring the cleaning effect of the cleaning member. In addition, the cutting structure can be hidden inside the shell to prevent safety hazards caused by the exposure of the cutting structure.

[0007] In a possible implementation, each of the cutting structures includes a first side wall and a second side wall that are arranged opposite to each other. An end of the first side wall that faces away from the cleaning member is connected to an end of the second side wall that faces away from the cleaning member, and a cutting edge is formed at the connection between the first side wall and the second side wall. A first preset angle is formed between the first side wall and the second side wall, and the value range of the first preset angle is 15°-90°.

[0008] By setting the cutting structure to include a first side wall and a second side wall, and connecting the end of the first side wall facing away from the cleaning member with the end of the second side wall facing away from the cleaning member, a relatively sharp cutting edge is formed at the connection between the first side wall and the second side wall, so as to cut the windings wound on the cleaning member, thereby preventing the windings from being wound around the cleaning member, and by setting the value range of the first preset angle to 15°-90°, the sharpness of the cutting edge can be ensured, the cutting effect of the cutting structure on the windings can be improved, and the windings can be prevented from being wound around the cleaning member, making the cleaning member difficult to clean.

[0009] In a possible implementation, the first preset angle has a value range of 20°-70°.

[0010] By setting the value range of the first preset angle to 20°-70°, the sharpness of the cutting blade can be further guaranteed, the cutting effect of the cutting structure on the entangled objects can be improved, and the entangled objects can be prevented from being entangled on the cleaning piece, making the cleaning piece difficult to clean.

[0011] In a possible implementation, the first preset angle has a value range of 30°-60°.

[0012] By setting the value range of the first preset angle to 30°-60°, the sharpness of the cutting blade can be further guaranteed, the cutting effect of the cutting structure on the entangled objects can be improved, and the entangled objects can be prevented from being entangled on the cleaning piece, making the cleaning piece difficult to clean.

[0013] In a possible implementation, the scraper assembly includes a fixed end and a free end that are arranged opposite to each other. The fixed end is used to connect to the housing. The free end is used to at least partially insert the cleaning member when the cleaning member rotates. The cutting structure extends from the free end of the scraper assembly toward the fixed end.

[0014] When the cleaning member rotates, the free end of the scraper assembly is at least partially inserted into the cleaning member so that the free end of the scraper assembly can hook the windings wound on the cleaning member, and as the cleaning member rotates, the windings move from the free end of the scraper assembly to the fixed end relative to the scraper assembly so as to support the windings. During the rotation of the cleaning member, the windings are cut by the cutting structure located on the side of the scraper assembly away from the cleaning member. When the windings are cut, they can be sucked into the sewage tank connected to the cleaning member from the sewage suction port. By setting the cutting structure from the free end of the scraper assembly, the windings can be cut by the cutting structure as soon as they are hooked, which can increase the cutting effect and cutting efficiency of the cutting structure.

[0015] In a possible implementation, the scraper assembly includes a scraper body. In the axial direction of the cleaning member, the scraper body includes a plurality of scraping teeth arranged at intervals. A side of each scraping tooth facing away from the cleaning member includes the cutting structure.

[0016] By arranging the scraper assembly to include a scraper body, and arranging a plurality of scraping teeth arranged at intervals on the scraper body, it is possible to conveniently hook up the entangled objects on the cleaning member, so as to improve the cutting efficiency of the scraper assembly.

[0017] In a possible implementation, the cutting structure protrudes outward from a side of the scraping tooth away from the cleaning member, wherein the orthographic projection of the cutting structure in the direction from the scraper assembly to the cleaning member is located on the scraping tooth.

[0018] By arranging the cutting structure to protrude outward from the side of the scraper teeth away from the cleaning member, the cutting structure and the scraper teeth can be an integrated structure, which can reduce the difficulty of processing and further reduce the cost. By arranging the orthographic projection of the cutting structure in the direction from the scraper assembly to the cleaning member on the scraper teeth, the cutting structure can be prevented from occupying the space between adjacent scraper teeth, reducing the difficulty of processing, preventing the scraper teeth from being broken due to uneven force, and improving the aesthetics of the scraper teeth.

[0019] In a possible implementation, a dimension of a side of the cutting structure close to the scraping teeth in the axial direction of the cleaning member is smaller than a dimension of a side of the scraping teeth away from the cleaning member in the axial direction of the cleaning member.

[0020] By setting the size of the side of the cutting structure facing the scraper to be smaller than the size of the side of the scraper facing away from the cleaning member, the first preset angle between the first side wall and the second side wall can be made smaller while the protrusion height of the cutting structure remains the same. In other words, the cutting edge can be made sharper, thereby improving the cutting effect and cutting efficiency of the cutting structure.

[0021] In a possible implementation, the scraper tooth includes a tooth root and a tooth top, wherein the tooth root is connected to the scraper body, and the tooth top is the free end of the scraper tooth, and the cutting structure extends from the tooth top toward the tooth root.

[0022] By extending the cutting structure from the tooth top toward the tooth root, the winding object can be cut by the cutting structure when it is hooked, thereby increasing the cutting effect and cutting efficiency of the cutting structure.

[0023] In a possible implementation, the size of the cross section of the tooth top of the skiving tooth is smaller than the size of the cross section of the tooth root.

[0024] By making the cross-sectional size of the tooth top of the scraper tooth smaller than the cross-sectional size of the tooth root, the tooth top size can be smaller, making it easier to hook up entangled objects, thereby improving the efficiency of the scraper body in picking up entangled objects, thereby improving the efficiency of the scraper body in cutting entangled objects, and improving the anti-entanglement effect of the cleaning piece.

[0025] In a possible implementation manner, in the direction from the tooth root to the tooth top, the size of the cross section of at least a portion of the skiving teeth gradually decreases.

[0026] By setting the cross-sectional dimensions of the scraping teeth to gradually decrease from the tooth root to the tooth top, the scraping teeth can be made into a tapered structure, so that the windings on the cleaning piece can be picked up more conveniently. And the supporting force of the picked windings can be gradually increased as they gradually go deeper into the scraping teeth, so that the maximum force point of the windings is at the cutting edge, thereby improving the cutting efficiency of the cutting structure.

[0027] In a possible implementation, the size of the side of the scraper facing the cleaning member in the axial direction of the cleaning member is a first size, and the size of the side of the scraper facing away from the cleaning member in the axial direction of the cleaning member is a second size, wherein the first size is greater than the second size.

[0028] By setting the first size to be larger than the second size, after the scraping teeth hook the winding object, the maximum force point of the winding object is at the cutting edge, thereby improving the cutting efficiency of the cutting structure.

[0029] In a possible implementation, from a side of the scraping teeth facing the cleaning member to a side of the scraping teeth facing away from the cleaning member, a size of at least part of the scraping teeth in the axial direction of the cleaning member gradually decreases.

[0030] By setting the axial size of the scraper teeth on the cleaning piece to gradually decrease from the side of the scraper teeth facing the cleaning piece to the side of the scraper teeth facing away from the cleaning piece, after the scraper teeth hook the entangled object, the maximum force point of the entangled object is at the cutting edge, thereby improving the cutting efficiency of the cutting structure, reducing the processing difficulty of the scraper teeth, and improving the aesthetics of the scraper teeth.

[0031] In a possible implementation, in the axial direction of the cleaning member, a distance between the tooth roots of two adjacent scraping teeth is between 2-5 mm.

[0032] By setting the distance between the roots of two adjacent scraper teeth to between 2-5 mm, the density of the scraper teeth can be increased, thereby improving the ability to pick up entangled objects and improving the efficiency of cutting entangled objects.

[0033] In a possible implementation, in the direction from the cleaning member to the scraper assembly, the scraper assembly includes at least two layers of scraper teeth disposed at intervals, wherein the distances from the cutting edges on the scraper teeth at different layers to the cleaning member are different.

[0034] By providing at least two layers of spaced-apart scraping teeth, the entangled materials on the cleaning piece can be cut in layers, thereby avoiding the problem of a single scraping tooth missing part of the entangled materials, thereby improving the efficiency of the scraper body in picking up the entangled materials, improving the cutting effect and cutting efficiency, and preventing the entangled materials from being entangled on the cleaning piece, making the cleaning piece difficult to clean.

[0035] In a possible implementation, the skiving teeth located at different layers have different sizes in the direction from the tooth root to the tooth top.

[0036] By setting the sizes of the scraping teeth on different layers in the direction from the tooth root to the tooth top differently, the space of the scraper body can be reasonably utilized to ensure that the tooth pitch between the scraping teeth is small, which can further improve the efficiency of the scraper body in picking up entangled objects, improve the cutting effect and cutting efficiency, and prevent entangled objects from being entangled on the cleaning parts, making the cleaning parts difficult to clean.

[0037] In a possible implementation manner, the skiving teeth located at different layers have the same size in the direction from the tooth root to the tooth top.

[0038] By setting the dimensions of the skiving teeth located in different layers in the direction from the tooth root to the tooth top to be the same, the difficulty of skiving tooth processing can be reduced, thereby reducing the production cost.

[0039] In a possible implementation, the scraping teeth are a linear structure.

[0040] By setting the scraping teeth to a linear structure, the processing difficulty of the scraping teeth can be reduced, thereby reducing the cost.

[0041] In a possible implementation, the scraping teeth are bent structures.

[0042] By arranging the scraping teeth as a bent structure, the scraping teeth can be easily inserted into the cleaning member, thereby improving the efficiency of the scraping teeth in picking up the winding objects, thereby improving the cutting efficiency of the scraper body.

[0043] In a possible implementation, the scraping tooth is an arrow-shaped structure, and the arrow points toward the tooth top of the scraping tooth.

[0044] The scraping teeth are arranged in an arrow-shaped structure so as to hook the winding objects on the cleaning member, thereby improving the efficiency of the scraping teeth in picking up the winding objects, and thereby improving the cutting efficiency of the scraper body.

[0045] In a possible implementation, when the scraping tooth is a bent structure, the scraping tooth includes a connecting portion and a bent portion. The connecting portion is used to connect the bent portion to the scraper body, and the bent portion is bent relative to the connecting portion in the axial direction of the cleaning member. The angle between the bent portion and the central axis of the cleaning member is between 0-90°.

[0046] By setting the angle between the bent portion and the central axis of the cleaning member to be between 0 and 90 degrees, it can be ensured that the free end of the scraper tooth hooks the winding material on the cleaning member, thereby ensuring the cutting efficiency of the scraper body.

[0047] In a possible implementation manner, the bending directions of the plurality of scraping teeth are the same.

[0048] By setting the bending directions of multiple scraping teeth to be the same, the aesthetics of the scraper body can be improved.

[0049] In a possible implementation, the scraper assembly includes a scraper surface facing the cleaning member, wherein at least a portion of the scraper surface is interference-fitted with the cleaning member.

[0050] By making at least part of the scraper surface and the cleaning member have an interference fit, the scraper assembly can be inserted into the implanted hair of the cleaning member, so as to conveniently hook up the windings wound on the cleaning member, thereby improving the cutting efficiency of the scraper assembly on the windings.

[0051] In a possible implementation, the floor brush assembly further includes a driving assembly. The driving assembly is connected to the cleaning member, and the driving assembly is used to drive the cleaning member to rotate forward or reversely. The scraper assembly is used to cut the windings on the cleaning member when the cleaning member rotates forward. The scraper assembly is also used to loosen the cleaning member when the cleaning member reverses.

[0052] The driving assembly is set to drive the rotation direction of the cleaning member, so that when the cleaning member rotates forward, the scraper assembly picks up the windings and cuts them. The forward rotation can be the rotation direction of the cleaning member when it is working normally. The windings wound on the cleaning member that are missed and not picked up due to the gap between the scraping teeth can be loosened by reversing the cleaning member. When the windings are loosened, the cleaning member can be rotated forward again to make the scraper assembly pick up the windings again and cut them. In this way, the forward and reverse rotations are alternated until the windings on the cleaning member are cleaned up, so as to prevent the windings from being entangled on the cleaning member, making it difficult to clean the cleaning member.

[0053] In a possible implementation, the floor brush assembly further includes a control device, wherein the control device is electrically connected to the drive assembly, and the control device is used to control the drive assembly to rotate forward or reverse.

[0054] By setting a control device, the driving component can be controlled so that the forward and reverse rotation of the cleaning component can be an automatically controlled process, which can improve the automation and intelligent performance of the floor brush component and enhance the user experience.

[0055] In a possible implementation, the scraper surface has a target interference point. A line connecting the target interference point and the rotation center of the cleaning member has a second preset angle with the scraper surface, and the value range of the second preset angle is 80-100°; wherein the target interference point is the point where the interference between the scraper surface and the cleaning member is the largest, and the rotation center of the cleaning member is the center of the circular surface of the cleaning member where the target interference point is located.

[0056] In this way, when the cleaning member is in normal working state, within the value range of the second preset angle, the scraper assembly and the cleaning member can be in contact, ensuring the relative sealing between the scraper assembly and the cleaning member. In this way, when the cleaning member drives the winding object to rotate to the position of the scraper assembly, the scraper assembly helps to weaken the airflow formed by the rotation of the cleaning member, and allows the winding object to be sucked away through the suction channel under the action of suction, effectively avoiding the problem of the winding object always being entangled on the cleaning member under the action of the airflow. At the same time, the scraper assembly can block the winding object that rotates to the position close to the suction channel, further reducing the probability of the winding object entangled with the cleaning member, realizing the separation of the winding object and the cleaning member, solving the problem of difficult cleaning of the winding object, and improving the cleaning effect of the floor scrubber.

[0057] In a possible implementation, a value range of the second preset angle is 85-95°.

[0058] In this way, within the above-mentioned value range, even if the shape or position of the scraper assembly changes, it can ensure that the scraper assembly and the cleaning member are in contact, thereby ensuring the relative sealing between the scraper assembly and the cleaning member, and the scraper surface and the cleaning member fit more closely, with a higher fitting effect.

[0059] In a possible implementation, a third preset angle is formed between a line connecting the target interference point and the rotation center of the cleaning member and a horizontal line where the rotation center of the cleaning member is located, and the value range of the third preset angle is -30-30°. When the third preset angle is a positive value, the target interference point is located above the horizontal line, and when the third preset angle is a negative value, the target interference point is located below the horizontal line.

[0060] In this way, when the cleaning member is in normal working state, within the value range of the third preset angle, the scraper assembly always maintains an interference state with the cleaning member, which is beneficial to the separation of the entangled object and the cleaning member and reduces the frequency of the entangled object entangled with the cleaning member.

[0061] In a possible implementation, the third preset angle has a value range of 0-30°.

[0062] In this way, the scraper assembly is located above the horizontal line where the rotation center of the cleaning element is located. On the basis of ensuring that the suction force of the entire machine on the ground is not reduced, the suction force exerted on the entangled material around the scraper assembly is opposite to the direction of the entanglement force generated by the rotation of the cleaning element on the entangled material, which is more conducive to peeling off the entangled material and achieving the separation of the entangled material and the cleaning element.

[0063] In a possible implementation, the scraper assembly includes a connector, wherein the connector is used to connect the scraper body to the housing.

[0064] By providing a connector to connect the scraper body and the housing, the design flexibility of the scraper body can be improved. In addition, the structure of the scraper body can be simplified, thereby reducing the difficulty of processing the scraper body. In addition, by connecting the scraper body and the housing through a connector, when a problem occurs with the scraper body, only the scraper body can be replaced, which can reduce the maintenance cost of the floor brush assembly.

[0065] In a possible implementation, the floor brush assembly further includes a sewage suction channel. One end of the sewage suction channel is connected to the accommodating cavity, and the other end is used to communicate with a sewage tank on the body. At least part of the cutting structure is located in the sewage suction channel. The cutting structure is arranged toward the sewage suction channel.

[0066] By providing a dirt suction channel, garbage on the surface to be cleaned can be sucked away through the dirt suction channel, and the cut windings can also be sucked away from the dirt suction channel. By arranging at least part of the cutting structure in the dirt suction channel, the cutting structure can be hidden in the inner corner of the shell, thereby preventing the potential safety hazards caused by the exposure of the cutting structure.

[0067] In a possible implementation, the cleaning member is used to clean the surface to be cleaned.

[0068] By cleaning the surface to be cleaned with the cleaning member and cleaning the cleaning member with the provided scraper assembly at the same time, the surface cleanliness of the cleaning member can be improved, thereby improving the cleaning efficiency and cleaning effect of the cleaning member.

In addition, the cutting structure can be hidden inside the shell, and the safety hazards caused by the exposure of the cutting structure can be prevented.

And it can effectively prevent the cutting structure from damaging the hair implantation of the cleaning member.

[0118] It should be noted that, for the convenience of description, in the embodiment of the present application, the thickness direction of the shell of the floor brush assembly is taken as the z direction, the axial direction of the cleaning element is taken as the x direction, and the direction from the cleaning element to the shell is taken as the y direction.

[0119] The present application embodiment provides a floor brush assembly 100, such as Figure 1 As shown, the floor brush assembly 100 may include a housing 10, a cleaning member 20 and a scraper assembly 30. Figure 2 As shown, the housing 10 may include a housing cavity 12, and the housing cavity 12 is used to accommodate the cleaning member 20. The cleaning member 20 is rotatably connected to the housing 10 and is located in the housing cavity 12. The scraper assembly 30 is connected to the housing 10, and the side of the scraper assembly 30 facing the cleaning member 20 is at least partially interference-fitted with the cleaning member 20. The side of the scraper assembly 30 facing away from the cleaning member 20 is provided with a plurality of cutting structures 312, and the cutting structures 312 are at least used to cut the windings located on the cleaning member 20.

[0120] It should be noted that the entangled objects may be waste such as long and thin hairs. In the embodiments of the present application, the specific types of the entangled objects are not further limited.

[0121] like Figure 1 As shown, the floor brush assembly 100 may further include a roller so that the floor brush assembly 100 can be moved for user convenience, which can save effort and enhance user experience.

[0122] For example, the cleaning member 20 may be a roller brush, and the outer side of the roller brush is provided with implanted hair 21 (see Figure 3As shown), the implanted hair 21 is relatively soft and will be flattened during operation, so the side of the scraper assembly 30 facing the cleaning member 20 is at least partially interference-fitted with the cleaning member 20, so that the scraper assembly 30 can be inserted into the implanted hair 21. The specific structure of the cleaning member 20 is not further limited in the application embodiment.

[0123] Exemplarily, the cleaning member 20 can be used to clean the surface to be cleaned. In practical applications, the surface to be cleaned generally refers to the cleaning surface that needs to be cleaned by the floor brush assembly 100, which can generally be the ground or carpet, etc., and can be a flat surface or a slope, etc. When the floor brush assembly 100 is located on the surface to be cleaned, part of the structure of the cleaning member 20 of the floor brush assembly 100 can be tangent to the surface to be cleaned. In the embodiment of the present application, the surface to be cleaned is not further limited.

[0124] The cleaning member 20 cleans the surface to be cleaned and the scraper assembly 30 cleans the cleaning member 20 at the same time, so that the surface cleanliness of the cleaning member 20 can be improved, thereby improving the cleaning efficiency and cleaning effect of the cleaning member 20.

[0125] It should be noted that in the embodiments of the present application, "towards" refers to orientation in a broad sense, and is not limited to a frontal relative arrangement; and "deviating from" refers to deviation in a broad sense, and is not limited to a back-to-back parallel relative arrangement.

[0126] It should be noted that "interference fit" refers to the limitation of the interference amount and degree of fit between the scraper assembly 30 and the cleaning member 20. The interference amount refers to the dimensional deviation that is allowed to exceed the design size during assembly to ensure that the scraper assembly 30 and the cleaning member 20 can achieve good fit or connection during assembly or processing; the degree of fit refers to the size, shape, angle and other conditions of the contact surface between the scraper assembly 30 and the cleaning member 20. In this way, during the installation process, the connection tightness between the scraper assembly 30 and the cleaning member 20 can be improved, which helps to prevent the scraper assembly 30 and the cleaning member 20 from falling off, so as to ensure that the scraper assembly 30 can be inserted into the implanted hair 21 of the cleaning member 20, so as to facilitate the hooking of the windings wrapped around the cleaning member 20 and improve the separation efficiency of the windings and the cleaning member 20.

[0127] The floor brush assembly 100 in the embodiment of the present application is provided with a housing 10, thereby providing an installation position for other components of the floor brush assembly 100 to improve the aesthetics of the cleaning assembly. In addition, the housing 10 can protect the parts located in the housing 10 and prevent the parts in the housing 10 from falling dust. By providing a housing cavity 12 on the housing 10, a housing space is provided for the cleaning member 20. By providing a scraper assembly 30, and at least partially interfering with the cleaning member 20 on one side of the scraper assembly 30 facing the cleaning member 20, the scraper assembly 30 can pick up the windings wound on the cleaning member 20, and the windings can be prevented from being wound on the cleaning member 20. By providing a cutting structure 312 on one side of the scraper assembly 30 away from the cleaning member 20, the scraper assembly 30 can pick up and cut the windings wound on the cleaning member 20, so that the cut windings can be separated from the cleaning member 20, so that the cut windings can be sucked from the sewage suction port 131 of the floor brush assembly 100 into the sewage tank connected to the cleaning member 20. Based on the prior art, an additional cutting assembly is used to clean the cleaning member, which can easily damage the implanted hair on the cleaning member during the cleaning process, thereby affecting the subsequent cleaning effect of the cleaning member. Therefore, in the present application, the cutting structure 312 is arranged on the side of the scraper assembly 30 away from the cleaning member 20, which can effectively prevent the cutting structure 312 from damaging the implanted hair 21 of the cleaning member 20 while ensuring the cleaning effect of the cleaning member 20. In addition, the cutting structure 312 can be hidden inside the housing 10, which can prevent the potential safety hazards caused by the exposure of the cutting structure 312.

[0128] For example, Figure 2 As shown, the housing 10 may include a front cover plate 11, which is located on the top of the cleaning member 20. In the axial direction (x direction) of the cleaning member 20, the two ends of the housing 10 are respectively provided with a fixing frame 15, one end of the fixing frame 15 is connected to the housing 10, and the other end is rotatably connected to the cleaning member 20, and a receiving cavity 12 is formed between the side of the front cover plate 11 facing the cleaning member 20 and the two fixing frames 15. Among them, the front cover plate 11 can be used to cover part of the cleaning member 20, so as to prevent the cleaning member 20 from flying dust during operation. Exemplarily, the front cover plate 11 can be a transparent arc-shaped plate structure.

[0129] In a possible implementation, the floor brush assembly 100 further includes a sewage suction channel 13. Figure 3 As shown, one end of the sewage suction channel 13 is connected to the accommodating chamber 12, and the other end is used to communicate with the sewage tank on the body. Exemplarily, a sewage suction port 131 is provided at one end of the sewage suction channel 13 facing the accommodating chamber 12, and the sewage suction port 131 is located on the shell 10. By providing the sewage suction channel 13, garbage on the surface to be cleaned can be sucked away through the sewage suction channel 13, and the cut winding objects can also be sucked away from the sewage suction channel 13.

[0130] For example, Figure 4 As shown, in the z direction, the two ends of the sewage suction port 131 are provided with a first side edge 16 and a second side edge 17 which are arranged opposite to each other. Among them, the second side edge 17 is close to the surface to be cleaned, and the scraper assembly 30 is arranged on the first side edge 16. The cleaning member 20 is spaced apart from the second side edge 17. A scraper bar 14 and the like can be arranged on the second side edge 17, and the scraper bar 14 extends outside the sewage suction port 131 in the z direction, so that a closed space is formed between the cleaning member 20, the surface to be cleaned (not shown in the figure), the scraper bar 14, the accommodating cavity 12 and the sewage suction port 131, so as to facilitate the garbage on the surface to be cleaned to be sucked away from the sewage suction channel 13.

[0131] It should be noted that "opposite arrangement" refers to face-to-face arrangement, which can be arranged diagonally face-to-face or directly face-to-face. In the embodiment of the present application, "close" refers to close in a broad sense, and is not limited to facing each other directly. Figure 3 and Figure 4 The arrow in the figure may point to the direction in which garbage such as entanglements are sucked into the sewage tank (not shown in the figure).

[0132] Of course, in other embodiments, the end of the sewage suction channel 13 away from the accommodating chamber 12 can also be connected to a container for accommodating garbage, such as a dust box. In the embodiment of the present application, the device for connecting the end of the sewage suction channel 13 away from the accommodating chamber 12 is not further limited.

[0133] like Figure 5 As shown, at least part of the scraper assembly 30 is located in the accommodating chamber 12. At least part of the cutting structure 312 is located in the sewage suction channel 13, and the cutting structure 312 is arranged toward the sewage suction channel 13. By arranging at least part of the cutting structure 312 in the sewage suction channel 13, the cutting structure 312 can be hidden in the inner corner of the housing 10, thereby preventing the potential safety hazards caused by the exposure of the cutting structure 312.

[0134] In a possible implementation, an air guide wall 132 may be provided between the first side edge 16 and the second side edge 17 of the sewage suction port 131 (see Figure 2 and Figure 3 As shown), the two air guide walls 132 extend from the two ends of the shell 10 along the x-direction toward the direction close to the sewage suction port 131, and the end of the air guide wall 132 close to the sewage suction port 131 gradually extends in the direction away from the accommodating cavity 12, and forms the sewage suction port 131 at a position close to the middle of the shell 10 along the x-direction.

[0135] It should be noted that in the embodiment of the present application, the specific shape of the sewage suction port 131 is not limited and can be designed according to actual conditions.

[0136] By providing the wind guide wall 132, the garbage such as the entangled objects at the two ends of the cleaning member 20 can be gathered to the sewage suction port 131 and then sucked into the sewage suction channel 13. By providing the sewage suction port 131 at a position close to the middle of the housing 10 along the x direction, the distance from the garbage at the end of the cleaning member 20 along the x direction to the sewage suction port 131 can be reduced, that is, the travel of the garbage at the end of the cleaning member 20 to the sewage suction port 131 can be reduced, so that the cleaning effect of the floor brush assembly 100 can be improved.

[0137] Exemplarily, the sewage suction channel 13 may include a hose structure. In the embodiment of the present application, the specific structure of the sewage suction channel 13 is not further limited.

[0138] like Figure 6 As shown, the scraper assembly 30 may include a scraper body 31 and a connector 32. The connector 32 is used to connect the scraper body 31 to the housing 10. Exemplarily, in the z direction, one end of the connector 32 is connected to the first side edge 16 of the opening of the housing 10, and the other end of the connector 32 is connected to the scraper body 31.

[0139] By providing a connector 32 to connect the scraper body 31 and the housing 10, the design flexibility of the scraper body 31 can be improved. In addition, the structure of the scraper body 31 can be simplified, thereby reducing the difficulty of processing the scraper body 31. In addition, by connecting the scraper body 31 and the housing 10 through the connector 32, when there is a problem with the scraper body 31, only the scraper body 31 can be replaced, which can reduce the maintenance cost of the floor brush assembly 100.

[0140] In some embodiments, the connection member 32 is configured as a water divider for providing water from the clean water tank to the cleaning member 20 .

[0141] Continue to see Figure 6 As shown, in the axial direction (x direction) of the cleaning member 20, the scraper body 31 includes a plurality of scraping teeth 311 arranged at intervals. The scraping teeth 311 can extend along the z direction. Each scraping tooth 311 has a cutting structure 312 on a side facing away from the cleaning member 20 (see Figure 7 shown).

[0142] By configuring the scraper assembly 30 to include a scraper body 31 and configuring a plurality of spaced scraping teeth 311 on the scraper body 31 , it is possible to conveniently hook up the entangled objects on the cleaning member 20 , so as to improve the cutting efficiency of the scraper assembly 30 .

[0143] In a possible implementation, the cutting structure 312 protrudes outward from the side of the scraper tooth 311 facing away from the cleaning member 20. The orthographic projection of the cutting structure 312 in the direction from the scraper assembly 30 to the cleaning member 20 is located on the scraper tooth 311. In other words, the cutting structure 312 is located on the scraper tooth 311, and no structure extends to the outside of the scraper tooth 311. In this way, the connection area between the cutting structure 312 and the scraper tooth 311 can be increased, thereby improving the connection stability between the cutting structure 312 and the scraper tooth 311, thereby extending the service life of the scraper tooth 311. In addition, by setting the cutting structure 312 to protrude outward from the side of the scraper tooth 311 facing away from the cleaning member 20, the cutting structure 312 and the scraper tooth 311 can be an integrated structure, which can reduce the difficulty of processing and thus reduce costs.

[0144] For example, in the x direction, the cutting structure 312 can be arranged in the middle of the scraping teeth 311, so that the top of the cutting structure 312 can be the point where the winding material is subjected to the greatest force, which can improve the cutting efficiency of the cutting part. By arranging the orthographic projection of the cutting structure 312 in the direction from the scraper assembly 30 to the cleaning member 20 on the scraping teeth 311, it can prevent the cutting structure 312 from occupying the space between adjacent scraping teeth 311, reduce the difficulty of processing, prevent the scraping teeth 311 from being subjected to uneven force and causing the scraping teeth 311 to break, etc., and improve the aesthetics of the scraping teeth 311.

[0145] Of course, in some embodiments, in the x-direction, the cutting structure 312 can also be set at other positions of the scraper tooth 311. For example, the cutting structure 312 can be set close to one side of the scraper tooth 311 in the x-direction. In the embodiment of the present application, the position of the cutting structure 312 located on the scraper tooth 311 in the x-direction is not further limited.

[0146] The cutting structure 312 is described in detail below with reference to the accompanying drawings.

[0147] like Figure 8 As shown, each cutting structure 312 includes a first side wall 3121 and a second side wall 3122 that are arranged opposite to each other. The end of the first side wall 3121 that faces away from the cleaning member 20 is connected to the end of the second side wall 3122 that faces away from the cleaning member 20, and a cutting edge 3123 is formed at the connection between the first side wall 3121 and the second side wall 3122. There is a first preset angle α between the first side wall 3121 and the second side wall 3122, and the value range of the first preset angle α is 15°-90°.

[0148] By setting the cutting structure 312 to include a first side wall 3121 and a second side wall 3122, and connecting the end of the first side wall 3121 away from the cleaning member 20 with the end of the second side wall 3122 away from the cleaning member 20, a relatively sharp cutting blade 3123 is formed at the connection between the first side wall 3121 and the second side wall 3122, so as to cut the windings wound on the cleaning member 20, thereby preventing the windings from being wound around the cleaning member 20, and by setting the value range of the first preset angle to 15°-90°, the sharpness of the cutting blade 3123 can be ensured, the cutting effect of the cutting structure 312 on the windings can be improved, and the windings can be prevented from being wound around the cleaning member 20, making the cleaning member 20 difficult to clean.

[0149] It should be noted that in the z direction, the first preset angle α at different positions of the scraper 311 can be the same or different, and can be specifically determined according to the shape of the cutting structure 312. In the embodiment of the present application, the value of the first preset angle at different positions of the scraper 311 in the z direction is not further limited.

[0150] Among them, the first side wall 3121 and the second side wall 3122 can be a straight slope or an arc-shaped slope. When the first side wall 3121 and the second side wall 3122 are arc-shaped slopes, the first preset angle α can be the angle between the cross-sections of the first side wall 3121 and the second side wall 3122 near the intersection of the first side wall 3121 and the second side wall 3122.

[0151] Exemplarily, the first preset angle α can be any value between 15 and 90°; for example, it can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 60°, 65°, 70°, 75°, 80°, 85° or 90°, etc. In the embodiment of the present application, the value of the first preset angle α is not further limited.

[0152] In a possible implementation, the first preset angle α has a value range of 20°-70°.

[0153] By setting the value range of the first preset angle α to 20°-70°, the sharpness of the cutting blade 3123 can be further ensured, the cutting effect of the cutting structure 312 on the entangled objects can be improved, and the entangled objects can be prevented from being entangled on the cleaning member 20, making the cleaning member 20 difficult to clean.

[0154] In a possible implementation, the first preset angle α has a value range of 30°-60°.

[0155] By setting the value range of the first preset angle α to 30°-60°, the sharpness of the cutting blade 3123 can be further guaranteed, the cutting effect of the cutting structure 312 on the entangled objects can be improved, and the entangled objects can be prevented from being entangled on the cleaning member 20, making the cleaning member 20 difficult to clean.

[0156] In one possible implementation, see Figure 8 As shown, the size of the scraper 311 facing the cleaning member 20 in the x direction is a first size D1. The size of the scraper 311 facing away from the cleaning member 20 in the x direction is a second size D2. The first size D1 is greater than the second size D2.

[0157] By setting the first size to be larger than the second size, after the scraping teeth 311 hook the winding object, the maximum force point of the winding object is at the cutting edge 3123, thereby improving the cutting efficiency of the cutting structure 312.

[0158] In a possible implementation, the size of at least part of the scraping teeth 311 in the x direction gradually decreases from the side of the scraping teeth 311 facing the cleaning member 20 to the side of the scraping teeth 311 facing away from the cleaning member 20. That is, starting from a certain position, the size of the scraping teeth 311 in the x direction gradually decreases from the side of the scraping teeth 311 facing the cleaning member 20 to the side of the scraping teeth 311 facing away from the cleaning member 20. It can also be said that starting from a certain position, at least one side surface of the scraping teeth 311 in the x direction gradually shrinks inwards.

[0159] For example, in the y direction, the size of the scraping teeth 311 in the x direction between the middle of the scraping teeth 311 and the side of the scraping teeth 311 facing away from the cleaning member 20 gradually decreases. Of course, the size of the scraping teeth 311 in the x direction may also gradually decrease from other positions to the side of the scraping teeth 311 facing away from the cleaning member 20. In the embodiment of the present application, the initial position where the scraping teeth 311 begin to shrink is not further limited.

[0160] By setting the axial dimension of at least part of the scraper teeth 311 on the cleaning member 20 to gradually decrease from the side of the scraper teeth 311 facing the cleaning member 20 to the side of the scraper teeth 311 facing away from the cleaning member 20, after the scraper teeth 311 hook the entangled object, the maximum force point of the entangled object is at the cutting edge 3123, thereby improving the cutting efficiency of the cutting structure 312, reducing the processing difficulty of the scraper teeth 311, and improving the aesthetics of the scraper teeth 311.

[0161] In the embodiment of the present application, a dimension of a surface of the cutting structure 312 close to the scraping teeth 311 in the x direction is a third dimension D3, wherein the third dimension D3 is smaller than the second dimension D2.

[0162] By setting the size of the side of the cutting structure 312 facing the scraper 311 to be smaller than the size of the side of the scraper 311 facing away from the cleaning member 20, the first preset angle between the first side wall 3121 and the second side wall 3122 can be made smaller while the protrusion height of the cutting structure 312 remains the same. In other words, the cutting edge 3123 can be made sharper, thereby improving the cutting effect and cutting efficiency of the cutting structure 312.

[0163] In a possible implementation, the scraper assembly 30 may include a fixed end 30a and a free end 30b that are disposed opposite to each other (see Figure 5 ). The fixed end 30a is used to connect with the housing 10. The free end 30b is used to at least partially insert into the cleaning member 20 when the cleaning member 20 rotates. The cutting structure 312 extends from the free end 30b of the scraper assembly 30 toward the fixed end 30a.

[0164] When the cleaning member 20 rotates, the free end 30b of the scraper assembly 30 is at least partially inserted into the cleaning member 20 so that the free end 30b of the scraper assembly 30 can hook the windings wound on the cleaning member 20, and as the cleaning member 20 rotates, the windings move from the free end 30b of the scraper assembly 30 to the fixed end 30a relative to the scraper assembly 30 so as to support the windings. During the rotation of the cleaning member 20, the windings are cut by the cutting structure 312 located on the side of the scraper assembly 30 away from the cleaning member 20. When the windings are cut, they can be sucked into the sewage tank connected to the cleaning member 20 from the sewage suction port 131. By setting the cutting structure 312 from the free end 30b of the scraper assembly 30, the windings can be cut by the cutting structure 312 at the first time when they are hooked, which can increase the cutting effect and cutting efficiency of the cutting structure 312.

[0165] For example, Fig. 9 As shown, the scraper tooth 311 may include a tooth root 3111 and a tooth top 3112. The tooth root 3111 is connected to the scraper body 31, and the tooth top 3112 is the free end of the scraper tooth 311, that is, the free end 30b of the scraper assembly 30. The cutting structure 312 extends from the tooth top 3112 toward the tooth root 3111.

[0166] By extending the cutting structure 312 from the tooth top 3112 toward the tooth root 3111 , the winding object can be cut by the cutting structure 312 immediately when it is hooked, thereby increasing the cutting effect and efficiency of the cutting structure 312 .

[0167] In a possible implementation, the size of the cross section of the tooth top 3112 of the skiving tooth 311 is smaller than the size of the cross section of the tooth root 3111 .

[0168] By making the cross-sectional size of the tooth top 3112 of the scraper tooth 311 smaller than the cross-sectional size of the tooth root 3111, the size of the tooth top 3112 can be smaller, which is convenient for hooking up entangled objects, thereby improving the efficiency of the scraper body 31 in picking up entangled objects, and then improving the efficiency of the scraper body 31 in cutting entangled objects, thereby improving the anti-hair entanglement effect of the cleaning member 20.

[0169] Exemplarily, in the direction from the tooth root 3111 to the tooth top 3112, the size of the cross section of at least part of the scraping tooth 311 gradually decreases. For example, in the z direction, the size of the cross section of the scraping tooth 311 located between the middle of the scraping tooth 311 and the tooth top 3112 gradually decreases. Of course, the size of the cross section can also gradually decrease starting from other positions of the scraping tooth 311, and the specific shape of the scraping tooth 311 is not further limited in the embodiment of the present application.

[0170] It should be noted that the "cross section" refers to the cross section obtained by cutting the scraper 311 in a direction perpendicular to the central axis of the scraper 311. When the scraper 311 is in a straight line, the central axis of the scraper 311 is in the z direction. When the scraper 311 is in a bent structure, the directions of the central axes of different areas of the scraper 311 are different. Among them, the central axis refers to the central axis of the extension direction of the scraper 311, and the scraper 311 extends from the tooth root 3111 to the tooth top 3112. The "size of the cross section" refers to the area of ​​the closed area formed by the outer contour of the cross section.

[0171] By setting the cross-sectional dimensions of the scraping teeth 311 to gradually decrease from the tooth root 3111 to the tooth top 3112, the scraping teeth 311 can be made into a tapered structure, so that the windings on the cleaning member 20 can be picked up more conveniently. In addition, the supporting force of the picked windings can be gradually increased as the windings gradually penetrate into the scraping teeth 311, so that the maximum force point of the windings is at the cutting edge 3123, thereby improving the cutting efficiency of the cutting structure 312.

[0172] In a possible implementation, in the axial direction of the cleaning member 20, the spacing d between the tooth roots 3111 of two adjacent scraping teeth 311 is between 2-5 mm. For example, it can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc. Alternatively, it can also be 2.1 mm, 2.2 mm, 2.8 mm, 3.3 mm, 4.8 mm, etc. In the embodiment of the present application, the spacing between the tooth roots 3111 of two adjacent scraping teeth 311 is not further limited. In the specific design, the density of the scraping teeth 311 can be selected according to the cleaning needs and the density of the hair implants 21 on the cleaning member 20, and there is no specific limitation.

[0173] By setting the spacing between the tooth roots 3111 of two adjacent scraping teeth 311 to be between 2-5 mm, the density of the scraping teeth 311 can be increased, thereby improving the ability to pick up windings and improving the efficiency of cutting windings. Of course, in some embodiments, the spacing between the tooth roots 3111 of two adjacent scraping teeth 311 can also be other values. In the embodiment of the present application, the spacing between the tooth roots 3111 of two adjacent scraping teeth 311 is not further limited.

[0174] In the embodiment of the present application, there is no limitation on the tooth height of the scraping teeth 311 , and the tooth heights may be equal or unequal. In the specific design, scraping teeth 311 with corresponding tooth heights may be designed according to cleaning requirements to achieve more thorough cleaning.

[0175] It should be noted that the scraping teeth 311 may be a linear structure. By setting the scraping teeth 311 as a linear structure, the difficulty of processing the scraping teeth 311 can be reduced, thereby reducing the cost.

[0176] Of course, in other embodiments, such as Fig.10 As shown, the scraping teeth 311 can also be a bent structure. By setting the scraping teeth 311 as a bent structure, it is convenient to insert the scraping teeth 311 into the cleaning member 20, thereby improving the efficiency of the scraping teeth 311 picking up the windings, thereby improving the cutting efficiency of the scraper body 31.

[0177] Exemplarily, when the scraping tooth 311 is a bent structure, the scraping tooth 311 may include a connecting portion 3113 and a bending portion 3114. The connecting portion 3113 is used to connect the bending portion 3114 to the scraper body 31, and the bending portion 3114 is bent relative to the connecting portion 3113 in the axial direction of the cleaning member 20. The angle between the bending portion 3114 and the central axis of the cleaning member 20 is between 0-90°. The central axis of the connecting portion 3113 may be in the z direction.

[0178] By setting the angle between the bending portion 3114 and the central axis of the cleaning member 20 to be between 0° and 90°, it is possible to ensure that the tooth tops 3112 of the scraping teeth 311 hook the entangled objects on the cleaning member 20 , thereby ensuring the cutting efficiency of the scraper body 31 .

[0179] In some embodiments, the bending directions of the plurality of scraping teeth 311 may be the same. By setting the bending directions of the plurality of scraping teeth 311 to be the same, the aesthetics of the scraper body 31 can be improved. Of course, in some embodiments, the bending directions of the plurality of scraping teeth 311 may also be set to be different, which can improve the design flexibility of the scraper body 31.

[0180] In one possible implementation, Fig.11 As shown, the scraping tooth 311 is an arrow-shaped structure, and the arrow points toward the tooth top 3112 of the scraping tooth 311 .

[0181] The scraping teeth 311 are arranged in an arrow-shaped structure so as to hook the entangled objects on the cleaning member 20 , thereby improving the efficiency of the scraping teeth 311 in picking up the entangled objects, thereby improving the cutting efficiency of the scraper body 31 .

[0182] In one possible implementation, Fig.12 As shown, in the direction from the cleaning member 20 to the scraper assembly 30, that is, in the y direction, the scraper assembly 30 includes at least two layers of spaced scraper teeth 311. The distances from the cutting edges 3123 on the scraper teeth 311 at different layers to the cleaning member 20 are different.

[0183] By providing at least two layers of spaced-apart scraping teeth 311, the entangled materials on the cleaning member 20 can be cut in layers, thereby avoiding the problem of a single scraping tooth 311 missing part of the entangled materials, thereby improving the efficiency of the scraper body 31 in picking up the entangled materials, improving the cutting effect and cutting efficiency, and preventing the entangled materials from being entangled on the cleaning member 20, making the cleaning member 20 difficult to clean.

[0184] Exemplarily, at least two layers of scraping teeth 311 can be arranged on one scraper body 31, or on at least two scraper bodies 31, and then at least two scraping teeth 311 bodies are arranged at intervals along the y direction, etc. In the embodiment of the present application, the arrangement of at least two layers of scraping teeth 311 is not further limited.

[0185] In the embodiment of the present application, the cutting structure 312 directly protrudes from the scraping teeth 311, and the first side wall 3121 and the second side wall 3122 of the cutting structure 312 are respectively connected to the side walls of the scraping teeth 311 in the x direction. Of course, in other embodiments, the size of the side of the cutting structure 312 close to the scraping teeth 311 in the x direction can also be set to be smaller than the size of the side of the scraping teeth 311 away from the cleaning member 20 in the x direction. In the embodiment of the present application, the specific structure of the cutting structure 312 is not further limited.

[0186] In a possible implementation, the sizes of the scraping teeth 311 located at different layers in the direction from the tooth root 3111 to the tooth top 3112 may be the same or different. In the embodiment of the present application, the sizes of the scraping teeth 311 located at different layers in the direction from the tooth root 3111 to the tooth top 3112 are not further limited.

[0187] By setting the sizes of the scraping teeth 311 located at different layers in the direction from the tooth root 3111 to the tooth top 3112 to be different, the space of the scraper body 31 can be reasonably utilized, and the tooth pitch between the scraping teeth 311 can be ensured to be small, which can further improve the efficiency of the scraper body 31 in picking up winding objects, improve the cutting effect and cutting efficiency, and prevent the winding objects from being wound around the cleaning member 20, making it difficult to clean the cleaning member 20. By setting the sizes of the scraping teeth 311 located at different layers in the direction from the tooth root 3111 to the tooth top 3112 to be the same, the processing difficulty of the scraping teeth 311 can be reduced, thereby reducing the production cost.

[0188] It should be noted that in the embodiment of the present application, the number of layers of the scraping teeth 311 is not limited. For example, the scraper body 31 may include two layers of scraping teeth 311, which are stacked; or the scraper body 31 may include three layers of scraping teeth 311, which are stacked; or the scraper body 31 may include more layers of scraping teeth 311, and adjacent scraping teeth 311 are stacked. This embodiment does not limit this.

[0189] In a possible implementation, the material of the cutting structure 312 may be a plastic material, a metal material, or a ceramic material with strong rigidity. The cutting structure 312 may be fixed to the side of the scraping teeth 311 away from the cleaning member 20 by various assembly methods such as integral injection molding, hot stamping molding, or secondary injection molding. In the embodiment of the present application, the material of the cutting structure 312 and the connection method of the cutting structure 312 and the scraping teeth 311 are not further limited.

[0190] In the above-mentioned embodiment, an embodiment is introduced in which the cutting structure 312 is connected to the side of the scraper assembly 30 which is away from the cleaning. In some embodiments, the cutting structure 312 can also be arranged at other positions.

[0191] like Fig.13 As shown, in the x direction, the scraper tooth 311 includes a first side surface 3115 and a second side surface 3116 that are oppositely disposed, and a cutting structure 312 is disposed on the first side surface 3115 , the second side surface 3116 , and between two adjacent scraper teeth 311 .

[0192] In a possible implementation, the tooth top 3112 of the skiving tooth 311 is provided with an arrow-shaped structure.

[0193] The tooth top 3112 of the scraper tooth 311 is set to an arrow-shaped structure so as to hook the entangled objects on the cleaning member 20 , thereby improving the efficiency of the scraper tooth 311 in picking up the entangled objects, thereby improving the cutting efficiency of the scraper body 31 .

[0194] By providing the cutting structure 312 on the first side surface 3115, the second side surface 3116 and between two adjacent scraping teeth 311, the scraper assembly 30 can cut the windings wound around the cleaning member 20, so that the cut windings can be separated from the cleaning member 20 and sucked into the sewage tank connected to the cleaning member 20 through the sewage suction channel 13. The cutting structure 312 can be effectively prevented from damaging the implanted hairs 21 of the cleaning member 20. In addition, the cutting structure 312 can be hidden inside the housing 10, so as to prevent the potential safety hazards caused by the exposure of the cutting structure 312.

[0195] In some other embodiments, the cutting structure 312 and the scraper assembly 30 may be provided separately.

[0196] like Fig.14 As shown, the present application provides a floor brush assembly 100, including a shell 10, a cleaning member 20, a scraper assembly 30 and a cutting structure 312. The shell 10 includes a housing chamber 12. The cleaning member 20 is disposed in the housing chamber 12 and is rotatably connected to the shell 10. The scraper assembly 30 is connected to the shell 10, and a side of the scraper assembly 30 facing the cleaning member 20 is at least partially interference-fitted with the cleaning member 20. The cutting structure 312 is located on a side of the scraper assembly 30 that is away from the cleaning member 20, and is spaced apart from the scraper assembly 30. The cutting structure 312 is at least used to cut windings located on the cleaning member 20.

[0197] It should be noted that the structure, principle and connection relationship of the housing 10 and the cleaning member 20 in the embodiment of the present application are similar to those described above. Figures 1 to 12 The same as the embodiment shown in FIG. 1 , so the structure of the housing 10 and the cleaning member 20 can refer to the above embodiment. Figures 1 to 12 The description in the embodiments of the present application is not further limited.

[0198] For example, Fig.14 As shown, the scraper assembly 30 may include a scraper body 31 and a connecting member 32, wherein the connecting member 32 is used to connect the scraper body 31 to the housing 10. In the axial direction (x direction) of the cleaning member 20, the scraper body 31 includes a plurality of scraping teeth 311 arranged at intervals. The scraping teeth 311 may extend along the z direction.

[0199] like Fig.15 As shown, the cutting structure 312 is located on a side of the scraper body 31 away from the cleaning member 20, and is spaced apart from the scraper body 31. The cutting structure 312 may be a plate-shaped structure arranged along the x direction. In the z direction, one end of the cutting structure 312 is fixedly connected to the scraper body 31, and the other end extends along the z direction in a direction away from the scraper body 31. In addition, in the z direction, a cutting blade 3123 is provided at one end of the cutting structure 312 away from the scraper body 31.

[0200] The floor brush assembly 100 in the embodiment of the present application is provided with a housing 10, thereby providing an installation position for other components of the floor brush assembly 100 to improve the aesthetics of the cleaning assembly. In addition, the housing 10 can protect the components located in the housing 10 and prevent the components in the housing 10 from falling dust. A receiving cavity 12 is provided on the housing 10 to provide a receiving space for the cleaning member 20. A scraper assembly 30 is provided, and at least a part of the scraper assembly 30 facing the cleaning member 20 is interference-fitted with the cleaning member 20, so that the scraper assembly 30 can pick up the windings wound on the cleaning member 20, and the windings can be prevented from being wound on the cleaning member 20. A cutting structure 312 is provided on a side of the scraper assembly 30 facing away from the cleaning member 20 and is spaced apart from the scraper assembly 30 so that the scraper assembly 30 can cut the windings wound around the cleaning member 20. This allows the cut windings to be separated from the cleaning member 20 and sucked into a sewage tank connected to the cleaning member 20 through the sewage suction channel 13. The cutting structure 312 can be effectively prevented from damaging the implanted hairs 21 of the cleaning member 20. In addition, the cutting structure 312 can be hidden inside the shell 10 to prevent safety hazards caused by exposure of the cutting structure 312.

[0201] It should be noted that, in the embodiment of the present application, the distance between the cutting structure 312 and the scraper body 31 is not limited, and can be specifically set according to the structure of the cleaning member 20 .

[0202] In some embodiments, Fig.16 As shown, the scraper assembly 30 may further include a scraper surface 313 facing the cleaning member 20. At least a portion of the scraper surface 313 is interference-fitted with the cleaning member 20. By interference-fitting at least a portion of the scraper surface 313 with the cleaning member 20, the scraper assembly 30 can be inserted into the implanted hair 21 of the cleaning member 20, so as to facilitate the hooking of the windings wound on the cleaning member 20, thereby improving the scraper assembly 30's cutting efficiency of the windings.

[0203] In a possible implementation, the scraper surface 313 has a target interference point with the cleaning member 20 where the interference is the largest. A line connecting the target interference point and the rotation center of the cleaning member 20 has a second preset angle θ with the scraper surface 313, and the value range of the second preset angle θ is 80-100°.

[0204] It should be noted that the cleaning member 20 rotates around its own central axis, and the central axis of the cleaning member 20 is determined. The "rotation center" refers to the position of the central axis of the cleaning member 20 on the cross section perpendicular to the central axis of the cleaning member 20, that is, the position of the center of the cleaning member 20 on the cross section perpendicular to the central axis of the cleaning member 20. Exemplarily, the rotation center in the embodiment of the present application can be point C in the figure. On the cross section passing through the target interference point and perpendicular to the central axis of the cleaning member 20, the line connecting the target interference point and the rotation center of the cleaning member 20 is R in the figure.

[0205] It should be noted that the "target interference point" refers to the point with the largest interference between the scraper surface 313 and the cleaning member 20, that is, when the scraper assembly 30 and the cleaning member 20 are in interference fit, the scraper surface 313 and the cleaning member 20 are in contact, and the number of interference fit points between the scraper surface 313 and the cleaning member 20 is not less than one. Among them, when the number of interference fit points is one, the interference fit point is the target interference point; when the number of interference fit points is greater than one, for example, when the number of interference fit points is two, three or more, the interference fit point with the largest interference is the target interference point. It should be noted that "the maximum interference" refers to the state when the scraper surface 313 and the cleaning member 20 are in the tightest interference fit. The rotation center of the cleaning member 20 is the center of the circular surface of the cleaning member 20 where the target interference point is located.

[0206] In this way, by limiting the target interference point with the largest interference, the connection tightness between the scraper assembly 30 and the cleaning member 20 can be ensured, which helps prevent the scraper assembly 30 and the cleaning member 20 from becoming detached, thereby ensuring that the scraper assembly 30 can be inserted into the implanted hair 21 of the cleaning member 20, making it convenient to hook up the entangled objects wrapped around the cleaning member 20, thereby improving the separation efficiency of the entangled objects and the cleaning member 20.

[0207] Exemplarily, the second preset angle θ can be set to 80°, 85°, 90°, 95°, 98°, 100° or any point value between 80-100° according to actual needs, or can also be 81°, 82°, 83°, 91°, 92°, 99°, etc. The embodiment of the present application does not limit the specific value of θ, nor is it limited to the above examples.

[0208] If the value of the second preset angle is less than 80°, in this way, during the operation of the cleaning member 20, the scraper surface 313 is inclined toward one side of the cleaning member 20, and at this time at least part of the scraper surface 313 is located in the implanted hair 21 of the cleaning member 20, so that the entangled material is not easy to be hooked off, and part of the entangled material hooked off through the body 31 is easy to get stuck on the scraper assembly 30, and the entangled material is not easy to fall off, and the separation effect and separation efficiency of the entangled material are low. If the value of the second preset angle is greater than 100°, the contact area between the scraper surface 313 and the cleaning member 20 is reduced, and the contact between the scraper surface 313 and the cleaning member 20 cannot be well guaranteed, and thus the relative sealing between the scraper assembly 30 and the cleaning member 20 cannot be guaranteed. In this way, when the cleaning member 20 drives the entangled material to rotate to the position of the scraper assembly 30, the airflow formed by the rotation of the cleaning member 20 cannot be well weakened, and the entangled material is not easy to be sucked away.

[0209] Therefore, when the value of the second preset angle is any point value within the range of 80-100°, the scraper assembly 30 and the cleaning member 20 can be in contact, which is beneficial to ensure the relative sealing between the scraper assembly 30 and the cleaning member 20. In this way, when the cleaning member 20 drives the winding object to rotate to the position of the scraper assembly 30, under the action of the scraper assembly 30, it helps to weaken the airflow formed by the rotation of the cleaning member 20, and the winding object is sucked away through the suction port 131 under the action of suction, effectively avoiding the problem that the winding object is always entangled on the cleaning member 20 under the action of the airflow. At the same time, the scraper assembly 30 can block the winding object that rotates to the position close to the suction port 131, further reduce the probability of the winding object entangled with the cleaning member 20, realize the separation of the winding object and the cleaning member 20, solve the problem of difficult cleaning of the winding object, and improve the cleaning effect of cleaning equipment such as floor scrubbers.

[0210] In a possible implementation, the second preset angle θ has a value range of 85-95°.

[0211] It should be noted that when the value of θ is within the range of 85-95°, θ can be set to 85°, 90°, 92°, 95° or any value within the range of 85-95° according to actual needs.

[0212] It can be understood that when the value range of the second preset angle is 85-95°, the scraper assembly 30 can ensure that the scraper assembly 30 and the cleaning member 20 are in contact during the multi-angle setting process, thereby ensuring the relative sealing between the scraper assembly 30 and the cleaning member 20, and the scraper surface 313 and the cleaning member 20 are more closely fitted, and the fitting effect is higher.

[0213] In a possible implementation, a third preset angle λ is formed between a line connecting the target interference point and the rotation center of the cleaning member 20 and a horizontal line where the rotation center of the cleaning member 20 is located. The value range of the third preset angle λ is -30° to 30°.

[0214] As an explanation, since there are positive and negative values ​​in the z direction, when the third preset angle λ is positive, the target interference point is located above the horizontal line (e.g. Fig.16 As shown in FIG. 1 , when the third preset angle is a negative value, the target interference point is located below the horizontal line (as shown in FIG. Fig.17 When the third preset angle λ is 0°, the line connecting the target interference point and the rotation center of the cleaning member 20 is the same line as the horizontal line passing through the rotation center of the cleaning member 20.

[0215] It should be noted that when the value of λ is within -30-30°, λ can be set to -30°, -25°, -20°, -15°, -10°, 0°, 5°, 10°, 15°, 25°, 30° or any value between -30-30° according to actual needs. The embodiments of the present application do not limit the specific value of λ, nor are they limited to the above examples.

[0216] If the value of the third preset angle is less than -30°, the contact area between the scraper surface 313 and the cleaning member 20 is reduced, and the contact between the scraper surface 313 and the cleaning member 20 cannot be well guaranteed, and the relative sealing between the scraper assembly 30 and the cleaning member 20 cannot be guaranteed. In this way, when the cleaning member 20 drives the winding object to rotate to the position of the scraper assembly 30, the airflow formed by the rotation of the cleaning member 20 cannot be well weakened, and the winding object is not easy to be sucked away. If the value of the second preset angle is greater than 30°, the scraper surface 313 is inclined toward one side of the cleaning member 20. At this time, at least part of the scraper surface 313 is located in the implanted hair 21 of the cleaning member 20. In this way, the winding object is not easy to be hooked off, and a part of the winding object hooked off by the scraper assembly 30 is easy to get stuck on the scraper assembly 30, and the winding object is not easy to fall off. The separation effect and separation efficiency of the winding object are low.

[0217] Therefore, when the value of the third preset angle is any value within the range of -30-30°, the scraper assembly 30 and the cleaning element 20 always maintain an interference state. On the basis of ensuring that the suction force of the whole machine on the ground is not reduced, the suction force exerted on the entangled material around the scraper assembly 30 is opposite to the direction of the entanglement force generated by the rotation of the cleaning element 20 on the entangled material, which is more conducive to peeling off the entangled material and realizing the separation of the entangled material and the cleaning element 20.

[0218] In a possible implementation, in the embodiment of the present application, the value range of the third preset angle may be 0-30°.

[0219] It should be noted that when the value of λ is within the range of 0-30°, λ can be set to 0°, 10°, 15°, 20°, 25°, 28°, 30° or any value within the range of 0-30° according to actual needs. In this way, the scraper assembly 30 is located above the horizontal line where the rotation center of the cleaning member 20 is located, and on the basis of further ensuring that the suction force of the whole machine on the ground is not reduced, the suction force on the winding material around the scraper assembly 30 is opposite to the winding force generated by the rotation of the cleaning member 20 on the winding material, which is more conducive to peeling off the winding material and realizing the separation of the winding material and the cleaning member 20.

[0220] In a possible implementation, the floor brush assembly 100 may further include a driving assembly (not shown in the figure). The driving assembly is connected to the cleaning member 20, and the driving assembly is used to drive the cleaning member 20 to rotate forward or reverse. The scraper assembly 30 is used to cut the windings on the cleaning member 20 when the cleaning member 20 rotates forward. The scraper assembly 30 is also used to loosen the cleaning member 20 when the cleaning member 20 reverses.

[0221] It should be noted that the forward rotation may be the rotation direction of the cleaning member 20 when cleaning the surface to be cleaned, for example, it may be counterclockwise. Correspondingly, the reverse rotation may be the rotation direction opposite to the forward rotation direction, for example, it may be clockwise.

[0222] The driving assembly is set to drive the rotation direction of the cleaning member 20, so that when the cleaning member 20 rotates forward, the scraper assembly 30 picks up the windings and cuts them. The windings wound on the cleaning member 20 that are missed and not picked up due to the gap between the scraper teeth 311 can be loosened by reversing the cleaning member 20. When the windings are loosened, the cleaning member 20 can be rotated forward again to make the scraper assembly 30 pick up the windings again and cut them. In this way, the forward and reverse reciprocating rotations are alternated until the windings wound on the cleaning member 20 are cleaned up, so as to prevent the windings from being wound on the cleaning member 20, making it difficult to clean the cleaning member 20.

[0223] In a possible implementation, the floor brush assembly 100 may further include a control device, wherein the control device is electrically connected to the driving assembly, and the control device is used to control the driving assembly to rotate forward or reverse.

[0224] By setting a control device, the driving assembly can be controlled so that the forward and reverse rotation of the cleaning member 20 can be an automatically controlled process, which can improve the automation and intelligent performance of the floor brush assembly 100 and enhance the user experience.

[0225] An embodiment of the present application also provides a cleaning device, including a floor brush assembly and a body, wherein the floor brush assembly is rotatably connected to the body, and the floor brush assembly may be the floor brush assembly in any of the above embodiments.

[0226] The cleaning device provided in the embodiment of the present application can cut the entangled material wrapped around the cleaning piece by setting any of the above-mentioned floor brush assemblies, so that the cut entangled material can be separated from the cleaning piece and sucked into the sewage tank connected to the cleaning piece through the sewage suction channel, and the cutting structure can be effectively prevented from damaging the implanted hair of the cleaning piece. At the same time, the cutting structure can be hidden in the inner corner of the opening, so as to prevent the safety hazards caused by the exposure of the cutting structure.

[0227] It should be noted that the cleaning equipment in the embodiments of the present application includes but is not limited to a floor scrubber, a vacuum cleaner, a floor sweeper, etc. As long as the cleaning equipment has a cleaning function, it belongs to the protection scope of the embodiments of the present application.

[0228] An embodiment of the present application also provides a cleaning system, including a base station and the above-mentioned cleaning device.
