Description

Technical Field

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

[0002] With the continuous improvement of cleaning requirements and the continuous improvement of cleaning technology, various cleaning equipment has appeared in the field of cleaning and maintenance of various surfaces to be cleaned, such as wooden floors, tile floors, marble floors, etc.

[0003] In current cleaning equipment, such as floor scrubbers, when working, entanglements will inevitably be sucked into the cleaning parts. The entanglements are entangled in the cleaning parts, which can easily affect the normal operation of the cleaning equipment, make it difficult to clean the cleaning parts, and affect the cleaning effect of the floor scrubber. In the related art, in order to solve this problem, the user is required to manually clean the entanglements on the roller brush, or an additional cutting mechanism is provided on the cleaning equipment. This method can easily damage the hair implants on the cleaning parts, reduce the service life of the cleaning parts, and provide a poor user experience. Utility Model Content

[0004] The embodiments of the present application provide a floor brush assembly, a cleaning device and a cleaning system, in which the scraper and the cleaning member are in contact, which helps to ensure the relative sealing between the scraper and the cleaning member, thereby reducing the probability of the entangled objects being entangled with the cleaning member, achieving the separation of the entangled objects and the cleaning member, solving the problem of difficult cleaning of the entangled objects, and improving the cleaning effect of the floor scrubber.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a floor brush assembly, comprising a housing, wherein the housing has a receiving cavity;

[0007] A cleaning member is located in the accommodating cavity and is rotatably connected to the shell; a scraper is connected to the shell, the scraper is located on a side of the shell close to the cleaning member, and the scraper has a scraper surface facing the cleaning member; at least a portion of the scraper surface is in interference fit with the cleaning member. A line connecting a target interference point on the scraper surface and a rotation center of the cleaning member has a first preset angle with the scraper surface, and the value range of the first 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; 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.

[0008] In this way, when the cleaning member is in normal working state, at least part of the scraper surface and the cleaning member are interference fit, so that the scraper can easily hook up the windings wound on the cleaning member, so as to improve the scraper's separation efficiency of the windings; by limiting the value range of the first preset angle to 80-100°, in this way, if the value of the first preset angle is less than 80°, during the operation of the cleaning member, the scraper surface is inclined toward one side of the cleaning member, and at this time at least part of the scraper surface is located in the hair planting of the cleaning member, resulting in the windings not being easy to be hooked off, and part of the windings hooked off by the scraper are easy to get stuck on the scraper, the windings are not easy to fall off, and the separation effect and separation efficiency of the windings are low. If the value of the first preset angle is greater than 100°, the contact area between the scraper surface and the cleaning member is reduced, and the contact between the scraper surface and the cleaning member cannot be well guaranteed, and then the relative sealing between the scraper and the cleaning member cannot be guaranteed. In this way, when the cleaning member drives the windings to rotate to the scraper position, the airflow formed by the rotation of the cleaning member cannot be well weakened, and the windings are not easy to be sucked away. Therefore, within the value range of the first preset angle, the scraper and the cleaning member can be in contact, which is beneficial to ensure the relative sealing between the scraper and the cleaning member, weaken the airflow formed by the rotation of the cleaning member, and reduce the effect of the cleaning member on the entangled object at the location of the scraper. Then, under the action of the scraper, the entangled object and the cleaning member are separated, and the probability of the cleaning member being entangled by the entangled object is reduced. The problem of difficult cleaning of entangled objects is solved, and the cleaning effect of the floor scrubber is improved.

[0009] In a possible implementation, the first preset angle has a value range of 85-95°.

[0010] Thus, within the above value range, the scraper can ensure a reasonable interference between the scraper and the cleaning member during the multi-angle process of the scraper being tilted, thereby ensuring the relative sealing between the scraper and the cleaning member without affecting the normal operation of the cleaning member, and the scraper surface and the cleaning member fit more closely, thereby making the scraper have a better cleaning effect on the cleaning member. Moreover, within this value range, it helps to minimize the airflow formed by the rotation of the cleaning member, reduce the effect of the cleaning member on the entanglement at the location of the scraper, and thereby reduce the probability of the entanglement entangled with the cleaning member.

[0011] In a possible implementation, a line connecting the target interference point and the rotation center of the cleaning member has a second preset angle with a horizontal line passing through the rotation center of the cleaning member, and the value range of the second preset angle is -30-30°; wherein, when the second preset angle is a positive value, the target interference point is located above the horizontal line, and when the second preset angle is a negative value, the target interference point is located below the horizontal line.

[0012] In this way, if the value of the second preset angle is less than -30°, the contact area between the scraper surface and the cleaning member is reduced, and the good interference fit between the scraper surface and the cleaning member cannot be well guaranteed, and thus the relative sealing between the scraper and the cleaning member cannot be guaranteed. In this way, when the cleaning member drives the winding object to rotate to the scraper position, the airflow formed by the rotation of the cleaning member 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 distance between the position of the scraper and the suction channel is far, which is not conducive to the winding object being sucked away through the suction channel, affecting the cleaning effect. Therefore, when the value of the second preset angle is any value within the range of -30-30°, the scraper and the cleaning member always maintain an interference state, and on the basis of ensuring that the suction force of the whole machine on the ground is not reduced, the suction force on the winding object around the scraper is opposite to the winding force generated by the rotation of the cleaning member on the winding object, which is more conducive to peeling off the winding object, realizing the separation of the winding object and the cleaning member, and is conducive to the smooth suction of the winding object.

[0013] In a possible implementation, the second preset angle has a value range of 0-30°.

[0014] In this way, the scraper always maintains a reasonable interference state with the cleaning member, and the angle between the target interference point and the rotation center of the cleaning member and the horizontal line passing through the rotation center of the cleaning member is between 0-30°. In this way, on the one hand, the scraper can be located on the side of the cleaning member close to the dirt suction channel, ensuring a reasonable distance between the scraper and the dirt suction channel, thereby ensuring that the entangled objects taken off the hook can be smoothly sucked away through the dirt suction channel, improving the separation efficiency of the entangled objects, and ensuring the cleaning effect of the cleaning equipment; on the other hand, the scraper is located above the horizontal line where the rotation center of the cleaning member is located. Without affecting the normal operation of the cleaning member, the winding force generated by the rotation of the cleaning member on the entangled objects can be effectively offset by the suction force on the entangled objects, and the winding force direction of the entangled objects is opposite to the suction direction of the entangled objects, so that when the entangled objects rotate to the scraper position, it is more conducive to the scraper to peel off the entangled objects and realize the separation of the entangled objects and the cleaning member.

[0015] In a possible implementation, the scraper includes a scraper body, and in the extension direction of the scraper body, the scraper includes a plurality of scraping teeth arranged at intervals on the scraper body; wherein the extension direction of the scraper body is in the same direction as the axial direction of the cleaning member; wherein the scraper body is connected to the shell, and when the cleaning member rotates, at least part of the scraping teeth is interference fit with the cleaning member.

[0016] In this way, the entangled objects on the cleaning member can be conveniently hooked to improve the separation efficiency of the cleaning member and the entangled objects.

[0017] In a possible implementation, the target interference point is located on the scraper body, and the scraper surface at least includes a surface of the scraper body facing the cleaning member.

[0018] This is beneficial to ensure a reasonable interference fit between the scraper and the cleaning member, and will not affect the scraping teeth from hooking the entangled objects, thereby making it easier for the scraping teeth to hook the entangled objects on the cleaning member and improving the separation efficiency of the cleaning member and the entangled objects.

[0019] In a possible implementation, the target interference point is located on the scraping tooth, and the scraper surface includes at least one side of the scraping tooth facing the cleaning member.

[0020] This is beneficial to ensuring a reasonable interference between the scraper and the cleaning member, and will not be interfered with by the assembly with the housing.

[0021] In a possible implementation, the scraping tooth includes a tooth root and a tooth top, the tooth root is connected to the scraper body, the tooth top is the free end of the scraping tooth, and at least a portion of the tooth top is interference fit with the cleaning member.

[0022] In this way, the free end hooks the windings wound on the cleaning member, and as the cleaning member rotates, the windings move from the tooth top to the tooth root relative to the scraper, so as to peel off the windings and improve the separation efficiency of the cleaning member and the windings.

[0023] In a possible implementation, the scraping tooth is a planar structure; one end of the scraping tooth away from the scraper body is inclined toward the direction close to the cleaning member; or, one end of the scraping tooth away from the scraper body is inclined toward the direction away from the cleaning member; or, the extension direction of the scraping tooth is perpendicular to the horizontal direction.

[0024] In this way, the various structures of the scraping teeth can ensure that the first preset angle is within a value range, thereby ensuring that the scraper and the cleaning member are in contact, and further ensuring the relative sealing between the scraper and the cleaning member.

[0025] In a possible implementation, the scraping teeth are of a curved structure; the scraping teeth are bent in a direction approaching the cleaning member, or the scraping teeth are bent in a direction away from the cleaning member.

[0026] In this way, various structures of the scraping teeth can ensure that the first preset angle is within a value range, thereby ensuring that the scraper and the cleaning member are in contact, and further ensuring the relative sealing between the scraper and the cleaning member.

[0027] In one possible implementation, the scraping teeth are straight teeth, and the extension direction of the scraping teeth intersects with the extension direction of the scraper body perpendicularly or obliquely; or, the scraping teeth are curved teeth; or, the scraping teeth are bent teeth, and the scraping teeth include at least two interconnected scraping tooth segments, and the extension directions of two adjacent scraping tooth segments intersect, and the included angle is greater than 90°.

[0028] In this way, it is convenient to hook the entangled objects on the cleaning member, so as to improve the separation efficiency of the cleaning member and the entangled objects. In addition, when the scraping teeth are bent teeth, by limiting the included angle to be greater than 90°, it is convenient for the scraping teeth to be inserted into the implanted hair of the cleaning member to hook the entangled objects on the cleaning member, so as to improve the separation efficiency of the cleaning member and the entangled objects. Moreover, if the above-mentioned included angle is less than 90°, the entangled objects hooked on the cleaning member are not easy to be separated from the cleaning member, which affects the subsequent cleaning effect of the cleaning member. Therefore, the above-mentioned angle setting can also facilitate the separation of entangled objects on the cleaning member and improve the cleaning effect of the cleaning member.

[0029] In a possible implementation, when the scraping teeth are inclined straight teeth, multiple scraping teeth are inclined in the same direction; when the scraping teeth are curved teeth, multiple scraping teeth are bent in the same direction; when the scraping teeth are bent teeth, multiple scraping teeth are bent in the same direction.

[0030] In this way, the cleaning member can be easily inserted, thereby improving the efficiency of the scraper teeth in picking up the entangled objects and improving the separation efficiency of the cleaning member and the entangled objects. In addition, the same inclination direction of the scraper teeth can improve the structural regularity of the scraper.

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

[0032] In this way, on the one hand, it is helpful to avoid the problem that the entangled material is easy to be difficult to be sucked away when the distance between the roots of two adjacent scraping teeth is too small, and on the other hand, it is helpful to avoid the problem that the entangled material is difficult to hook up when the distance between the roots of two adjacent scraping teeth is too large. Therefore, within the above-mentioned value range, the density of the scraping teeth can be increased, the ability to pick up the entangled material can be improved, and the separation efficiency of the cleaning part and the entangled material can be improved, and there will be no blockage problem.

[0033] In a possible implementation, in the horizontal direction, the scraper includes at least two layers of the scraping teeth that are spaced apart, and the scraping teeth in two adjacent layers are staggered.

[0034] In this way, the resistance of the scraper teeth to the rotation of the cleaning member can be effectively reduced. At the same time, by hooking up the entangled materials on the cleaning member in layers, it is helpful to avoid the problem of a single layer of scraper teeth missing some entangled materials, thereby improving the efficiency of the scraper in picking up entangled materials, improving the anti-entanglement effect, and improving the separation efficiency of the cleaning member and the entangled materials, effectively avoiding the problem of entangled materials being entangled on the cleaning member, making the cleaning member difficult to clean.

[0035] In a possible implementation, the scraper includes a fixed section and a free section; wherein the fixed section is connected to the shell, the free section is connected to the fixed section, and at least a portion of the free section is interference fit with the cleaning member; the scraper surface includes at least the surface of the free section facing the cleaning member.

[0036] In this way, the scraper is connected to the shell through the fixed section, which is beneficial to increase the connection area between the scraper and the shell, thereby helping to improve the connection strength between the scraper and the shell, and ensuring the assembly stability and assembly strength of the scraper and the shell; the scraper surface is the surface of the free section facing the cleaning member, which is beneficial to ensure the contact between the scraper and the cleaning member on the one hand, and on the other hand, it is beneficial to ensure that the free section has enough space to change its shape or position and will not be interfered with by the assembly of the shell.

[0037] In a possible implementation, it also 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 the sewage tank on the fuselage; the sewage suction port of the sewage suction channel faces the cleaning member, and at least part of the scraper is located above the sewage suction port.

[0038] This helps to suck away the entangled objects from the sewage suction channel, facilitates the processing of the hooked entangled objects, improves the cleaning effect, and enhances the user experience.

[0039] In a possible implementation, one end of the scraper close to the sewage suction port is inclined toward the sewage suction port, so that the entangled objects taken off by the hook can be more easily sucked into the sewage suction channel.

[0040] In a possible implementation, the floor brush assembly includes a connecting piece, wherein the connecting piece is used to connect the scraper to the shell.

[0041] In this way, the design flexibility of the scraper can be improved, and the structure of the scraper can be simplified, reducing the difficulty of processing the scraper; in addition, connecting the scraper and the shell through a connecting piece is beneficial to avoiding structural interference between the shell and the scraper. In addition, when the scraper is damaged, only the scraper can be replaced, which can effectively reduce the maintenance cost of the floor brush assembly.

[0042] In a possible implementation manner, a plurality of cutting structures are formed on a side of the scraper facing away from the cleaning member, and the cutting structures are at least used to cut windings on the cleaning member.

[0043] In this way, the cutting structure can cut the entangled material wrapped around the cleaning piece, so that the cut entangled material is separated from the cleaning piece and sucked into the sewage tank connected to the cleaning piece through the sewage suction port of the floor brush assembly, and can effectively prevent the cutting structure from damaging the bristles of the cleaning piece. The cutting structure is hidden inside the shell, which can prevent safety hazards caused by the exposure of the cutting structure.

[0044] In a possible implementation, in the axial direction of the cleaning member, a plurality of scraping teeth arranged at intervals are formed on the scraper; and a surface of each scraping tooth facing away from the cleaning member includes the cutting structure.

[0045] In this way, the winding material hooked by each scraper tooth can be cut, thereby improving the cutting efficiency of the cutting structure.

[0046] In a possible implementation, the cutting structure protrudes outward from a side of the scraping tooth facing away from the cleaning member; wherein an orthographic projection of the cutting structure in a direction from the scraper plate to the cleaning member is located on the scraping tooth.

[0047] In this way, the cutting structure and the scraper teeth can be an integrated structure, which can reduce the processing difficulty and thus reduce the processing cost; by locating the orthographic projection of the cutting structure in the direction from the scraper teeth to the cleaning member on the scraper teeth, this can prevent the cutting structure from occupying the space between adjacent scraper teeth, thereby reducing the processing difficulty, and can prevent the scraper teeth from being broken due to uneven force, and at the same time can improve the aesthetics of the scraper teeth.

[0048] 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.

[0049] In this way, when the height of the protrusion of the cutting structure is the same, the cutting edge is made sharper, which is beneficial to improving the cutting effect and cutting efficiency of the cutting structure.

[0050] In a possible implementation, a driving member is further included; wherein the driving member is connected to the cleaning member, and the driving member is used to drive the cleaning member to rotate forward or reverse; the scraper is used to cut the entangled material on the cleaning member when the cleaning member rotates forward; the scraper is also used to loosen the entangled material on the cleaning member when the cleaning member reverses.

[0051] In this way, the driving member drives the cleaning member to rotate, so that when the cleaning member rotates forward, the scraper 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 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 pick up the windings again and cut them. In this way, the forward and reverse rotations are alternated until the windings wound on the cleaning member are cleaned up, so as to prevent the windings from being wound on the cleaning member, making it difficult to clean the cleaning member.

[0052] In a second aspect, an embodiment of the present application provides a cleaning device, comprising a body and a floor brush assembly, wherein the body is connected to the floor brush assembly.

[0053] The cleaning device provided in the embodiment of the present application, by including the above-mentioned floor brush assembly, can achieve contact between the scraper and the cleaning member within the value range of the first preset angle, which is beneficial to ensure the relative sealing between the scraper and the cleaning member, weaken the airflow formed by the rotation of the cleaning member, and reduce the effect of the cleaning member on the entangled object at the position of the scraper, and then under the action of the scraper, the separation of the entangled object and the cleaning member is achieved, and the probability of the cleaning member being entangled by the entangled object is reduced; at the same time, the scraper can block the entangled object that rotates to the vicinity of the suction port, further reduce the probability of the entangled object entangled with the cleaning member, and achieve the separation of the entangled object and the cleaning member, solve the problem of difficult cleaning of the entangled object, and improve the cleaning effect of the floor scrubber.

[0054] In a third aspect, an embodiment of the present application provides a cleaning system, including a base station and a cleaning device.

[0055] The cleaning system provided in the embodiment of the present application, by including the above-mentioned cleaning equipment, can achieve contact between the scraper and the cleaning member within the value range of the first preset angle, which is beneficial to ensure the relative sealing between the scraper and the cleaning member, weaken the airflow formed by the rotation of the cleaning member, and reduce the effect of the cleaning member on the entangled object at the position of the scraper. Then, under the action of the scraper, the separation of the entangled object and the cleaning member is achieved, and the probability of the cleaning member being entangled by the entangled object is reduced, thereby solving the problem of difficult cleaning of the entangled object and improving the cleaning effect of the floor scrubber.

[0089] In current cleaning equipment such as floor scrubbers, vacuum cleaners or sweeping robots, for example, when a floor scrubber uses a roller brush for cleaning, entanglements such as hair are entangled on the roller brush, which can easily cause the roller brush to stall, making it difficult to clean the roller brush and affecting the cleaning effect of the floor scrubber. Therefore, in the related art, the entanglements are generally cleaned, such as adding a cleaning device to the roller brush to cut and scrape off the entanglements. However, the above cleaning device makes it difficult to clean the entanglements, and the cleaning effect of the floor scrubber is poor.

[0090] Based on the above-mentioned technical problems, the embodiments of the present application provide a floor brush assembly, a cleaning device and a cleaning system. The floor brush assembly includes a shell, a cleaning member and a scraper. Within the value range of the first preset angle, the scraper and the cleaning member can be in contact with each other, which is beneficial to ensure the relative sealing between the scraper and the cleaning member, weaken the airflow formed by the rotation of the cleaning member, and reduce the effect of the cleaning member on the entangled object at the position of the scraper. Under the action of the scraper, the separation of the entangled object and the cleaning member is achieved, reducing the probability of the cleaning member being entangled by the entangled object, solving the problem of difficult cleaning of the entangled object and improving the cleaning effect of the floor scrubber.

[0091] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

For example, the forward direction of the floor brush assembly 100 may be the front end, and the direction opposite to the forward direction may be the rear end.

[0098] The structure of the floor brush assembly 100 provided in the embodiment of the present application is described below.

[0099] It should be noted that, for the convenience of description, in the embodiment of the present application, the axial direction of the cleaning member 120 is taken as the x-direction, and the horizontal direction is taken as the y-direction.

[0100] Reference Figure 2 and Figure 3 As shown, the floor brush assembly 100 may include a housing 110 and a cleaning member 120. The housing 110 has a receiving cavity 111. The receiving cavity 111 is used to receive at least part of the cleaning member 120. The cleaning member 120 is rotatably connected to the housing 110.

The front cover plate 114 can be used to shield part of the cleaning member 120, so as to prevent the cleaning member 120 from flying dust during operation. Exemplarily, the front cover plate 114 can be a transparent curved plate-like structure.

[0103] In some embodiments, a scraper bar 116 may be provided on the housing 110 , and the scraper bar 116 is in contact with the surface to be cleaned during operation, so that the sewage on the surface to be cleaned can be completely sucked away.

[0104] When the cleaning member 120 is working normally, the cleaning member 120 rotates on the surface to be cleaned. The entangled objects on the surface to be cleaned, such as hair, thread balls and other thin linear garbage, are easily entangled in the implanted hair of the cleaning member 120 itself, making it difficult to clean the cleaning member 120, and easily affecting the cleaning effect, hindering the normal operation of the floor brush assembly 100. Therefore, in order to separate the cleaning member 120 from the entangled objects and improve the cleaning effect of the cleaning member 120, in the embodiment of the present application, reference is made to Figures 4 to 8 As shown, the floor brush assembly 100 includes a scraper 130 , which is connected to the housing 110 . The scraper 130 is located on a side of the housing 110 close to the cleaning member 120 , and has a scraper surface 133 facing the cleaning member 120 .

[0105] It should be noted that, in the embodiment of the present application, "close" refers to close in a broad sense, and is not limited to facing each other head-on. Similarly, in the embodiment of the present application, "towards" also refers to close in a broad sense, and is not limited to facing each other head-on.

[0106] The scraper surface 133 is at least partially interference-fitted with the cleaning member 120, and a line connecting the target interference point on the scraper surface 133 and the rotation center of the cleaning member 120 has a first preset angle with the scraper surface 133, and the value range of the first preset angle is 80-100°. The scraper surface 133 may refer to the surface where the line connecting the maximum interference point and the minimum interference point between the scraper 130 and the cleaning member 120 is located.

[0107] It should be noted that, “at least part” in the phrase “at least part of the scraper surface 133 is in interference fit with the cleaning member 120” means that: in some embodiments, the entire scraper surface 133 is in interference fit with the cleaning member 120; or, in some embodiments, a part of the scraper surface 133 is in interference fit with the cleaning member 120, and the other part has no matching relationship with the cleaning member 120. This embodiment of the present application is not limited to this.

[0108] It should be noted that "interference fit" refers to the limitation of the interference amount and degree of fit between the scraper 130 and the cleaning member 120. The interference amount refers to the dimensional deviation that is allowed to exceed the design size during assembly to ensure that the scraper 130 and the cleaning member 120 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 surface 133 and the cleaning member 120. In this way, during the installation process, the connection tightness between the scraper 130 and the cleaning member 120 can be improved, which helps to prevent the scraper 130 from falling off from the cleaning member 120, so as to ensure that the scraper 130 can be inserted into the implanted hair of the cleaning surface, so as to facilitate the hooking of the windings wrapped around the cleaning member 120 and improve the separation efficiency of the windings and the cleaning member 120.

[0109] It should be noted that the "target interference point" is the point with the largest interference between the scraper surface 133 and the cleaning member 120, wherein the "point with the largest interference" means that when the scraper 130 and the cleaning member 120 are in interference fit, the number of interference fit points between the scraper surface 133 and the cleaning member 120 is not less than one. 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 largest interference" refers to the state where the scraper surface 133 and the cleaning member 120 are in interference fit with the maximum tension.

[0110] In this way, by limiting the target interference point with the largest interference, the connection tightness between the scraper 130 and the cleaning member 120 can be ensured, which helps prevent the scraper 130 from becoming detached from the cleaning member 120, thereby ensuring that the scraper 130 can be connected to the cleaning member 120, making it easy to hook up the entangled objects wrapped around the cleaning member 120, thereby improving the separation efficiency of the entangled objects and the cleaning member 120.

[0111] It should be noted that the "rotation center" of the cleaning member 120 may refer to: the center of the circular surface where the target interference point on the cleaning member is located. For example, the cleaning member 120 rotates around an axis, and the rotation axis of the cleaning member 120 is determined. With the target interference point as a reference, a cross section is made along the axis perpendicular to the cleaning member 120, and the cross section passes through the target interference point. The point where the cross section intersects with the axis is the rotation center in this article. For example, the rotation center in the embodiment of the present application may be point C in the figure (refer to Figures 9 to 16 shown).

[0112] In the embodiments of this application, refer to Figures 9 to 11As shown, a line connecting the target interference point and the rotation center of the cleaning member 120 has a first preset angle α with the scraper surface 133 , and the value range of the first preset angle may be 80-100°.

[0113] It should be noted that when the value of α is between 80-100°, α can be set to 80°, 85°, 90°, 95°, 98°, 100° or any 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 α, nor is it limited to the above examples.

[0114] If the value of the first preset angle is less than 80°, in this way, during the operation of the cleaning member 120, the scraper surface 133 is inclined toward one side of the cleaning member 120, and at least part of the scraper surface 133 is located in the hair implantation of the cleaning member 120, so that the windings are not easy to be hooked off, and part of the windings hooked off by the scraper 130 are easily stuck on the scraper 130, and the windings are not easy to fall off, and the separation effect and separation efficiency of the windings are low. If the value of the first preset angle is greater than 100°, the contact area between the scraper surface 133 and the cleaning member 120 is reduced, and the contact between the scraper surface 133 and the cleaning member 120 cannot be well guaranteed, and then the relative sealing between the scraper 130 and the cleaning member 120 cannot be guaranteed. In this way, when the cleaning member 120 drives the windings to rotate to the position of the scraper 130, the airflow formed by the rotation of the cleaning member 120 cannot be well weakened, and the windings are not easy to be sucked away.

[0115] Therefore, when the value of the first preset angle is any value within the range of 80-100°, the scraper 130 and the cleaning member 120 can be in contact, which is beneficial to ensure the relative sealing between the scraper 130 and the cleaning member 120. In this way, when the cleaning member 120 drives the winding object to rotate to the position of the scraper 130, under the action of the scraper 130, it helps to weaken the airflow formed by the rotation of the cleaning member 120, and makes the winding object be sucked away through the suction port 112 under the action of suction, effectively avoiding the problem that the winding object is always entangled on the cleaning member 120 under the action of airflow; at the same time, the scraper 130 can block the winding object that rotates to the vicinity of the suction port 112, further reducing the probability of the winding object entangled with the cleaning member 120, realizing the separation of the winding object and the cleaning member 120, solving the problem of difficult cleaning of the winding object, and improving the cleaning effect of the floor scrubber.

[0116] In a possible implementation, the first preset angle between a line connecting the target interference point and the rotation center of the cleaning member 120 and the scraper surface 133 may be in a range of 85-95°.

[0117] It should be noted that when the value of α is between 85-95°, α can be set to 85°, 90°, 92°, 95° or any value between 85-95° according to actual needs. Alternatively, it can also be 85°, 87°, 88°, 89°, 91°, 93°, etc. The embodiment of the present application does not limit the specific value of α, nor is it limited to the above examples.

[0118] If the value of the first preset angle is less than 85°, the scraper surface 133 is easily entangled with the hair implants of the cleaning member 120, and the entangled objects are not easy to be separated from the hair implants, and the entangled objects are not easy to be hooked off, and a part of the entangled objects hooked off by the scraper 130 is easy to get stuck on the scraper 130, and the entangled objects are not easy to fall off, and the separation effect and separation efficiency of the entangled objects are low. If the value of the first preset angle is greater than 95°, the interference fit between the scraper 130 and the cleaning member 120 is poor, resulting in poor sealing performance between the scraper 130 and the cleaning member 120, and thus the airflow formed by the rotation of the cleaning member 120 cannot be effectively weakened, and the entangled objects are not easy to be sucked away.

[0119] Therefore, when the value of the first preset angle is any value within the range of 85-95°, the scraper 130 can ensure a reasonable interference between the scraper 130 and the cleaning member 120 in the multi-angle tilt setting, which is beneficial to ensure the relative sealing between the scraper 130 and the cleaning member 120, and the scraper surface 133 and the cleaning member 120 are more closely fitted, thereby making the scraper 130 have a better cleaning effect on the cleaning member 120. Moreover, within this value range, it is helpful to minimize the airflow formed by the rotation of the cleaning member 120, reduce the effect of the cleaning member 120 on the entanglement at the location of the scraper 130, and thus reduce the probability of the entanglement entangled with the cleaning member 120.

[0120] In one possible implementation, referring to Figures 9 to 11 As shown, a second preset angle may be formed between a line connecting the target interference point and the rotation center of the cleaning member 120 and a horizontal line passing through the rotation center of the cleaning member 120 , and a value range of the second preset angle β may be -30-30°.

[0121] It should be noted that, since the vertical direction z has positive and negative values, when the second preset angle is positive, the target interference point is located above the horizontal line (see Fig. 9 When the second preset angle is negative, the target interference point is below the horizontal line (see Fig.10 As shown), when the second preset angle is 0°, the line connecting the target interference point and the rotation center of the cleaning member 120 is the same line as the horizontal line passing through the rotation center of the cleaning member 120 (see Fig.11 shown).

[0122] It should be noted that when the value of β is between -30-30°, β 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 β, nor are they limited to the above examples.

[0123] If the value of the second preset angle is less than -30°, the contact area between the scraper surface 133 and the cleaning member 120 is reduced, and the contact between the scraper surface 133 and the cleaning member 120 cannot be well guaranteed, and the relative sealing between the scraper 130 and the cleaning member 120 cannot be guaranteed. In this way, when the cleaning member 120 drives the winding object to rotate to the position of the scraper 130, the airflow formed by the rotation of the cleaning member 120 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 distance between the scraper 130 and the dirt suction channel 113 is far, which is not conducive to the winding object being sucked away through the dirt suction channel 113, affecting the cleaning effect.

[0124] Therefore, when the value of the second preset angle is any value within the range of -30-30°, the scraper 130 and the cleaning element 120 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 130 is opposite to the direction of the entanglement force generated by the rotation of the cleaning element 120 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 120.

[0125] In a possible implementation, in the embodiment of the present application, the second preset angle between the line connecting the target interference point and the rotation center of the cleaning member 120 and the horizontal line passing through the rotation center of the cleaning member 120 can range from 0 to 30°.

[0126] It should be noted that when the value of β is within the range of 0-30°, β can be set to 0°, 10°, 15°, 20°, 25°, 28°, 30° or any value between 0-30° according to actual needs. Alternatively, it can also be 5°, 12°, 18°, 22°, 26°, 29°, 30°, etc. The embodiment of the present application does not limit the specific value of β, nor is it limited to the above examples.

[0127] In this way, the scraper 130 always maintains a reasonable interference state with the cleaning member 120, and the angle between the target interference point and the rotation center of the cleaning member 120 and the horizontal line passing through the rotation center of the cleaning member 120 is between 0-30 degrees. In this way, on the one hand, the scraper 130 can be located on the side of the cleaning member 120 close to the dirt suction channel 113, ensuring that there is a reasonable distance between the scraper 130 and the dirt suction channel 113, thereby ensuring that the entangled objects hooked up can be smoothly sucked away through the dirt suction channel 113, thereby improving the separation efficiency of the entangled objects and ensuring the cleaning effect of the cleaning device 200; on the other hand, the scraper 130 is located above the horizontal line where the rotation center of the cleaning member 120 is located. Without affecting the normal operation of the cleaning member 120, the winding force generated by the rotation of the cleaning member 120 on the entangled objects can be effectively offset by the suction force exerted on the entangled objects, and the direction of the winding force on the entangled objects is opposite to the direction of the suction force exerted on the entangled objects. Therefore, when the entangled objects rotate to the position of the scraper 130, it is more conducive to the scraper 130 to peel off the entangled objects and realize the separation of the entangled objects and the cleaning member 120.

[0128] In one possible implementation, referring to Figure 6 As shown, the scraper 130 may include a scraper body 131, and in the extension direction of the scraper body 131, the scraper 130 may include a plurality of scraping teeth 132 spaced apart on the scraper body 131; wherein the extension direction of the scraper body 131 is in the same direction as the axial direction of the cleaning member 120. wherein the scraper body 131 is connected to the housing 110, and when the cleaning member 120 rotates, at least a portion of the scraping teeth 132 is interference fit with the cleaning member 120.

[0129] In some embodiments, the target interference point may be located on the scraper body 131, and the scraper surface 133 includes at least the surface of the scraper body 131 facing the cleaning member 120. In this way, it is beneficial to ensure a reasonable interference between the scraper 130 and the cleaning member 120, and will not affect the scraping teeth 132 from hooking the windings, thereby facilitating the scraping teeth 132 to hook the windings on the cleaning member 120, and improving the separation efficiency of the cleaning member 120 and the windings.

[0130] In some embodiments, the target interference point may also be located on the scraper teeth 132, and the scraper surface 133 includes at least one side of the scraper teeth 132 facing the cleaning member 120. In this way, it is beneficial to ensure a reasonable interference between the scraper 130 and the cleaning member 120, and will not be interfered with by the assembly between the housing 110.

[0131] In this way, when the cleaning member 120 works normally, the scraping teeth 132 are at least partially interference fit with the cleaning member 120, the scraping teeth 132 are fixed, and the cleaning member 120 rotates around the rotating shaft. When the entangled objects, such as hair, wrapped around the cleaning member 120 pass through the scraper 130, the scraping teeth 132 hook the entangled objects off the cleaning member 120, which can effectively prevent the entangled objects from being wrapped around the cleaning member 120, thereby improving the cleaning efficiency of the cleaning member 120 and increasing the service life of the cleaning member 120.

[0132] It should be noted that the multiple scraping teeth 132 are distributed at intervals along the axial direction of the cleaning member 120, so that they can correspond to the axial direction of the cleaning member 120, thereby helping the multiple scraping teeth 132 to hook up the entangled objects along the axial direction of the cleaning member 120 when the cleaning member 120 rotates. The contact area between the scraping teeth 132 and the cleaning member 120 is large, thereby achieving the separation of the entangled objects and the cleaning member 120 to the greatest extent.

[0133] In some embodiments, the number, density and shape of the scraping teeth 132 are not limited, and can be set according to actual conditions. In some embodiments, in addition to the scraping teeth 132, saw teeth and other structural forms can also be used, and the ends of the saw teeth are inserted into the implanted hair of the cleaning member 120, which is not limited in the embodiments of the present application.

[0134] In one possible implementation, referring to Figure 6 As shown, the scraping tooth 132 may include a tooth root 1321 and a tooth top 1322, wherein the tooth root 1321 is connected to the scraper body 131, and the tooth top 1322 is the free end of the scraping tooth 132, and at least a portion of the tooth top 1322 is interference fit with the cleaning member 120. In this way, the free end hooks the winding material wound on the cleaning member 120, and as the cleaning member 120 rotates, the winding material moves from the tooth top 1322 to the tooth root 1321 relative to the scraper 130, so as to support the winding material and improve the separation efficiency between the cleaning member 120 and the winding material.

[0135] It should be noted that the structure of the scraping teeth 132 is not limited in the embodiment of the present application.

[0136] For example, in this embodiment, the scraping teeth 132 may be a planar structure (see Figure 12 to Figure 14 Alternatively, in other embodiments, the scraping teeth 132 may be a curved structure (see Fig.15 and Fig.16 This embodiment does not limit this.

[0137] When the scraping teeth 132 are planar structures, in other embodiments, the end of the scraping teeth 132 away from the scraper body 131 can be inclined toward the direction close to the cleaning member 120 (see Fig.12Alternatively, in this embodiment, the end of the scraping tooth 132 away from the scraper body 131 may be inclined in a direction away from the cleaning member 120 (see Fig.13 Alternatively, in other embodiments, the extension direction of the scraping teeth 132 is perpendicular to the horizontal direction (see Fig.14 shown).

[0138] When the scraping teeth 132 are curved structures, in other embodiments, the scraping teeth 132 may be bent toward the direction close to the cleaning member 120 (see Fig.15 Alternatively, in other embodiments, the scraping teeth 132 may be bent in a direction away from the cleaning member 120 (see Fig.16 shown).

[0139] In this way, it is possible to ensure that the first preset angle is within a value range, thereby ensuring that the scraper 130 and the cleaning member 120 are in contact, and further ensuring the relative sealing between the scraper 130 and the cleaning member 120 .

[0140] It should be noted that the structure of the scraper teeth 132 includes but is not limited to the above-mentioned various methods, and can be specifically configured according to actual needs.

[0141] For example, in this embodiment, the scraping teeth 132 may be straight teeth (see Fig.17 and Fig.18 Alternatively, in this embodiment, the scraping teeth 132 may be bent teeth (see Figures 19 to 20 Alternatively, in other embodiments, the scraping teeth 132 may be curved teeth. This embodiment does not limit this.

[0142] When the scraping teeth 132 are straight teeth, the extension direction of the scraping teeth 132 is perpendicular or oblique to the extension direction of the scraper body 131. For example, when the scraping teeth 132 are inclined straight teeth, multiple scraping teeth 132 can be inclined in the same direction (refer to Fig.18 When the scraping teeth 132 are curved teeth, the plurality of scraping teeth 132 are bent in the same direction; when the scraping teeth 132 are bent teeth, the plurality of scraping teeth 132 are bent in the same direction (refer to Fig. 20 As shown). In this way, it is convenient to have an interference fit with the cleaning member 120, thereby improving the efficiency of the scraping teeth 132 in picking up the entangled objects, and improving the efficiency of separating the cleaning member 120 from the entangled objects. In addition, by setting the same inclination direction for the multiple scraping teeth 132, the structural regularity of the scraper 130 can be improved.

[0143] In other embodiments, different inclined straight-tooth scraping teeth 132 may also be inclined in different directions. Different curved scraping teeth 132 may also be bent in different directions. Different bent scraping teeth 132 may also be bent in different directions. In this way, the structural flexibility of the scraping teeth 132 may be improved to adapt to the hair planting of roller brushes with different structures, facilitate the insertion of the scraping teeth 132 into the hair planting of the roller brush, separate the hair entangled by the roller brush, and improve the cleaning effect of the cleaning member 120.

[0144] It should be noted that, refer to Fig. 20 As shown, when the scraper tooth 132 is a bent tooth, the scraper tooth 132 includes at least two interconnected scraper tooth segments, the extension directions of two adjacent scraper tooth segments intersect, and the angle γ can be greater than 90°. In this way, it is convenient for the scraper tooth 132 to be inserted into the implanted hair of the cleaning member 120 to hook the entangled material on the cleaning member 120, so as to improve the separation efficiency of the cleaning member 120 and the entangled material. In addition, if the above-mentioned angle is less than 90°, the entangled material hooked on the cleaning member 120 is not easy to be separated from the cleaning member 120, affecting the subsequent cleaning effect of the cleaning member 120. Therefore, the above-mentioned angle setting can also facilitate the separation of the entangled material on the cleaning member 120 and improve the cleaning effect of the cleaning member 120.

[0145] In one possible implementation, referring to Fig.18 and Fig. 20 As shown, in the axial direction of the cleaning member 120, the distance between the tooth roots 1321 of two adjacent scraping teeth 132 may be in the range of 2-5 mm. For example, the distance between the tooth roots 1321 of two adjacent scraping teeth 132 may be d.

[0146] It should be noted that when the value of d is between 2-5 mm, d can be set to 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or any value between 2-5 mm according to actual needs, or can also be 2.1 mm, 2.2 mm, 2.8 mm, 3.3 mm, 4.8 mm, etc. This embodiment does not limit the specific value of d, nor is it limited to the above examples. In the specific design, the density of the scraper teeth 132 can be selected according to the cleaning needs and the density of the hair implants on the cleaning member 120, and there is no specific limitation.

[0147] If the distance between the tooth roots 1321 of two adjacent scraping teeth 132 is less than 2 mm, the scraping teeth 132 are relatively dense, which will cause a certain resistance to the rotation of the cleaning member 120, affecting the rotation speed of the cleaning member 120. In addition, it is not easy for the entangled objects to pass between the adjacent scraping teeth 132 and be sucked away. In addition, if the distance between the tooth roots 1321 is too small, the shape of the tooth structure cannot be made. If the distance between the tooth roots 1321 of two adjacent scraping teeth 132 is greater than 5 mm, the scraping teeth 132 are relatively sparse, and the entangled objects that are hooked off are relatively small, and the anti-entanglement effect is poor. The entangled objects are easy to detach from between the scraping teeth 132 and are not easy to be sucked away, affecting the cleaning effect.

[0148] Therefore, when the distance between the tooth roots 1321 of two adjacent scraping teeth 132 is any value within the range of 2-5 mm, on the one hand, it is helpful to avoid the problem that the entangled material is easy to be difficult to be sucked away when the distance between the tooth roots 1321 of two adjacent scraping teeth 132 is too small, and on the other hand, it is helpful to avoid the problem that the entangled material is difficult to hook when the distance between the tooth roots 1321 of two adjacent scraping teeth 132 is too large. Therefore, within the above-mentioned value range, the density of the scraping teeth 132 can be increased, the ability to pick up the entangled material can be improved, and the separation efficiency of the cleaning element 120 and the entangled material can be improved, and there will be no blockage problem.

[0149] In some embodiments, the tooth height of the scraping teeth 132 is not limited, and the tooth heights can be equal or unequal. In specific design, scraping teeth 132 with corresponding tooth heights can be designed according to cleaning needs to achieve more thorough cleaning. The tooth height is the extension length of the scraping teeth 132 in the vertical direction.

[0150] In one possible implementation, in order to reduce the resistance of the scraping teeth 132 to the rotation of the cleaning member 120 and to improve the anti-entanglement effect, in an embodiment of the present application, in the horizontal direction, the scraper 130 may include at least two layers of scraping teeth 132 spaced apart, and the two adjacent layers of scraping teeth 132 are staggered.

[0151] It should be noted that the number of layers of the scraping teeth 132 is not limited. For example, the scraper 130 may include two layers of scraping teeth 132, which are arranged at intervals; or, the scraper 130 may include three layers of scraping teeth 132, which are arranged at intervals; or, the scraper 130 may include more layers of scraping teeth 132, and adjacent scraping teeth 132 are arranged at intervals. This embodiment does not limit this.

[0152] In this way, the entangled materials on the cleaning member 120 can be hooked up in layers, which is beneficial to avoiding the problem of a single-layer scraping tooth 132 missing some entangled materials, thereby improving the efficiency of the scraper 130 in picking up entangled materials, and improving the efficiency of separating the cleaning member 120 and the entangled materials, effectively avoiding the problem of entangled materials being entangled on the cleaning member 120, making the cleaning member 120 difficult to clean, thereby improving the cleaning efficiency of the cleaning member 120 and extending the service life of the cleaning member 120.

[0153] In some embodiments, the spacing between teeth of two adjacent layers of scraping teeth 132 may be equal or unequal. When the spacing between teeth of two adjacent layers of scraping teeth 132 is equal, the scraping teeth 132 of two adjacent layers may be staggered so that the teeth gaps of one layer correspond to the teeth gaps of another layer.

[0154] In some other embodiments, referring to Fig. 22 As shown, the scraper 130 may include a fixed section 134 and a free section 135; wherein the fixed section 134 is connected to the shell 110, the free section 135 is connected to the fixed section 134, at least a portion of the free section 135 is interference fit with the cleaning member 120, and the scraper surface 133 is the surface of the free section 135 facing the cleaning member 120.

[0155] It should be noted that the difference between this embodiment and the above-mentioned application embodiment is that: the scraper 130 of this embodiment is not provided with scraping teeth 132, and the free section 135 is a flat plate structure, so that the entangled objects can also be hooked up and the entangled objects and the cleaning member 120 can be separated.

[0156] In some embodiments, there is no limitation on the connection method between the fixing section 134 and the housing 110. For example, the fixing section 134 and the housing 110 may be connected by bonding, or the fixing section 134 and the housing 110 may be connected by a buckle and a slot, or the fixing section 134 and the housing 110 may be connected by a separate connector. This embodiment of the application does not limit this.

[0157] In this way, the scraper 130 is connected to the housing 110 through the fixed section 134, which is beneficial to increase the connection area between the scraper 130 and the housing 110, thereby improving the connection strength between the scraper 130 and the housing 110, and ensuring the assembly stability and assembly strength of the scraper 130 and the housing 110. The scraper surface 133 is the surface of the free section 135 facing the cleaning member 120. In this way, on the one hand, it is beneficial to ensure that the scraper 130 and the cleaning member 120 are in contact, and on the other hand, it is beneficial to ensure that the free section 135 has enough space to change its shape or position without being interfered with and affected by the assembly of the housing 110.

[0158] In one possible implementation, referring to Figure 3As shown, a suction port 112 may be provided on the housing 110, and the suction port 112 is horizontally oriented toward the cleaning member 120. In this way, the suction port 112 can suck away the entangled objects hooked by the scraper 130, thereby cleaning the entangled objects, improving the cleaning effect, and improving the user experience.

[0159] It should be noted that there is no limitation on the shape, size and position of the sewage suction port 112, and the design can be made according to the actual situation.

[0160] In one possible implementation, referring to Figure 3 and Figure 5 As shown, it may also include a sewage suction channel 113, one end of which is connected to the accommodating chamber 111, and the other end of the sewage suction channel 113 is used to communicate with the sewage tank on the fuselage 210; at least part of the scraper 130 is located above the sewage suction port 112 of the sewage suction channel 113.

[0161] It should be noted that the shape, size and position of the sewage suction channel 113 are not limited and can be designed according to actual conditions. For example, the sewage suction channel 113 can be a hose structure. In the embodiment of the present application, the specific structure of the sewage suction channel 113 is not further limited.

[0162] In this way, the suction port 112 can suck away the entangled objects hooked by the scraper 130, and suck them into the sewage tank through the suction channel 113, so as to clean the hooked entangled objects, improve the cleaning effect, and enhance the user experience. By locating at least part of the scraper 130 above the suction port 112 of the suction channel 113, it is helpful to suck away the entangled objects from the suction port 112.

[0163] In a possible implementation, one end of the scraper 130 close to the sewage suction port 112 can be tilted toward the sewage suction port 112. In this way, it is more convenient for the entangled objects taken off to be sucked into the sewage suction channel 113. It should be noted that the tilt angle of the scraper 130 is not limited and can be set according to actual needs during design.

[0164] In one possible implementation, referring to Fig.21 As shown, the floor brush assembly 100 may include a connector 140, wherein the connector 140 is used to connect the scraper 130 to the housing 110. In this way, the design flexibility of the scraper 130 can be improved, and the structure of the scraper 130 can be simplified, and the processing difficulty of the scraper 130 can be reduced; in addition, when the scraper 130 and the housing 110 are connected by the connector 140, when the scraper 130 is damaged, etc., only the scraper 130 can be replaced, which can effectively reduce the maintenance cost of the floor brush assembly 100.

[0165] In one possible implementation, referring to Fig.21 As shown, a plurality of cutting structures 150 may be formed on one side of the scraper 130 away from the cleaning member 120, and the cutting structures 150 are at least used to cut the windings on the cleaning member 120. In this way, the cutting structures 150 can cut the windings wound on the cleaning member 120, so that the cut windings are separated from the cleaning member 120 and sucked into the sewage tank from the sewage suction channel 113, and the cutting structures 150 can be effectively prevented from damaging the implanted hairs of the cleaning member 120. In addition, the cutting structures 150 can be hidden inside the housing 110, so as to prevent the potential safety hazards caused by the exposure of the cutting structures 150.

[0166] In a possible implementation, a plurality of scraping teeth 132 are formed on the scraper 130 in the axial direction of the cleaning member 120, and a side of each scraping tooth 132 facing away from the cleaning member 120 may include a cutting structure 150. In this way, the winding material hooked by each scraping tooth 132 can be cut, thereby improving the cutting efficiency of the cutting structure 150.

[0167] In a possible implementation, the cutting structure 150 protrudes outward from the side of the scraper 132 facing away from the cleaning member 120; wherein, the orthographic projection of the cutting structure 150 in the direction from the scraper 130 to the cleaning member 120 is located on the scraper 132. In other words, the cutting structure 150 is located on the scraper 132, and no structure extends to the outside of the scraper 132. In this way, the connection area between the cutting structure 150 and the scraper 132 can be increased, thereby improving the connection stability between the cutting structure 150 and the scraper 132, thereby extending the service life of the scraper 132. In addition, by setting the cutting structure 150 to protrude outward from the side of the scraper 132 facing away from the cleaning member 120, the cutting structure 150 and the scraper 132 can be an integrated structure, which can reduce the difficulty of processing and thus reduce costs.

[0168] In a possible implementation, the dimension of the side of the cutting structure 150 close to the scraping teeth 132 in the axial direction of the cleaning member 120 is smaller than the dimension of the side of the scraping teeth 132 away from the cleaning member 120 in the axial direction of the cleaning member 120. In this way, after the scraping teeth 132 hook the winding material, the maximum force point of the winding material is at the cutting edge, thereby improving the cutting efficiency of the cutting structure 150, reducing the processing difficulty of the scraping teeth 132, and improving the aesthetics of the scraping teeth 132.

[0169] In some embodiments, the material of the cutting structure 150 can be a plastic material, a metal material or a ceramic material with strong rigidity. The cutting structure 150 can be fixed to the side of the scraper 132 away from the cleaning member 120 by various assembly forms 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 150 and the connection method of the cutting structure 150 and the scraper 132 are not further limited.

[0170] In the above embodiment, an embodiment is introduced in which the cutting structure 150 is connected to a side of the scraper 130 facing away from the cleaning member 120. In some other embodiments, the cutting structure 150 may also be arranged at other positions.

[0171] In a possible implementation, the floor brush assembly 100 may also include a driving member; wherein the driving member is connected to the cleaning member 120, and the driving member is used to drive the cleaning member 120 to rotate forward or reverse; the scraper 130 is used to cut the entanglement located on the cleaning member 120 when the cleaning member 120 rotates forward; the scraper 130 is also used to loosen the entanglement located on the cleaning member 120 when the cleaning member 120 reverses.

[0172] It should be noted that the forward rotation may be the rotation direction of the cleaning member 120 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.

[0173] In this way, the driving member drives the cleaning member 120 to rotate, so that when the cleaning member 120 rotates forward, the scraper 130 hooks the entangled material, and by reversing the cleaning member 120, the entangled material tightened on the cleaning member 120 can be loosened. When the entangled material is loosened, the cleaning member 120 can be rotated forward to allow the scraper 130 to pick up the entangled material again and cut it. In this way, the forward and reverse rotations are alternately performed until the entangled material wrapped around the cleaning member 120 is cleaned up, thereby preventing the entangled material from being entangled on the cleaning member 120, making the cleaning member 120 difficult to clean.

[0174] In some embodiments, the type of the driving member is not limited, and the driving member can be a driving motor. In addition, the connection method between the driving member and the cleaning member 120 is not limited.

[0175] 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 member, and the control device is used to control the driving member to rotate forward or reverse. In this way, the forward and reverse rotation of the cleaning member 120 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.

[0176] Therefore, in the floor brush assembly 100, the cleaning device 200 and the cleaning system provided by the embodiment of the present application, the line connecting the target interference point with the largest interference between the scraper surface 133 and the cleaning member 120 and the rotation center of the cleaning member 120 has a first preset angle with the scraper surface 133, and the value range of the first preset angle is 80-100°. In this way, within the value range of the first preset angle, the scraper 130 and the cleaning member 120 can be in contact, which is beneficial to ensure the relative sealing between the scraper 130 and the cleaning member 120, weaken the airflow formed by the rotation of the cleaning member 120, and reduce the effect of the cleaning member 120 on the entanglement at the location of the scraper 130, and then under the action of the scraper 130, the entanglement and the cleaning member 120 are separated, and the probability of the cleaning member 120 being entangled by the entanglement is reduced, which solves the problem of difficult cleaning of the entanglement and improves the cleaning effect of the floor scrubber.
