[0038] Devices such as vacuum cleaners, floor washers, and floor sweeping robots can facilitate users to clean the floor and are gradually widely used. To further improve the cleaning ability of the above devices, generally speaking, the above devices are all provided with a rotary brush, and the rotary brush is used to sweep up dust, sundries, etc. on the floor for cleaning. However, the sundries usually include long filamentous substances such as hair, thin ropes, and slender fibers. During the rotation of the rotary brush, the long filamentous substances such as hair will wind around the rotary brush. As the use time increases, a large amount of long filamentous substances such as hair accumulate in the rotary brush, which will hinder the rotation of the rotary brush, affect the dust removal effect. At the same time, after the device is used, it is necessary to manually clean the long filamentous substances such as hair in the rotary brush, which increases the cleaning labor intensity of the user, affects the use experience, and is inconvenient to use.

[0039] For this reason, referring to Figures 1 to 9 As shown, an embodiment of the first aspect of the present invention provides a floor brush assembly, which is applied to cleaning devices such as vacuum cleaners, floor washers, and floor sweeping robots. By sweeping the floor, the floor brush assembly can make it easy for the cleaning device to clean dust, sundries, etc. on the floor.

[0040] The structure of the floor brush assembly will be described in detail below by taking the floor brush assembly in a vacuum cleaner as an example.

[0041] Referring to Figures 1 to 3As shown, it can be understood that the floor brush assembly includes a housing 100, a roller brush body 200, and a cleaning component 300. Specifically, the housing 100 includes a base 110 and an upper cover 120. The upper cover 120 is detachably installed on the upper side of the base 110. The upper cover 120 can be connected to the base 110 by screws, snaps, etc. A chamber 130 is defined between the base 110 and the upper cover 120. The chamber 130 has a columnar structure and is arranged horizontally. An opening 111 is provided at the bottom of the base 110. The opening 111 is generally rectangular and is located directly below the chamber 130. The opening 111 communicates with the chamber 130. When the vacuum cleaner is working, dust, debris, etc. on the floor enter the chamber 130 through the opening 111.

[0042] It can be understood that, for facilitating the observation of the situation inside the chamber 130, the upper cover 120 is configured as a transparent member. For example, the upper cover 120 is a transparent plastic member, so that the user can observe the chamber 130 through the transparent upper cover 120 to know the working condition and the amount of debris inside the chamber 130, so as to manually clean the chamber 130 in time when it is blocked to ensure the cleaning efficiency of the vacuum cleaner. Of course, the upper cover 120 can be an opaque member and is provided with a viewing window. For example, the upper cover 120 is an opaque plastic member. The viewing window is generally rectangular and is located at the middle position of the upper cover 120. A transparent plastic plate is installed at the viewing window. Therefore, the user can also observe the chamber 130 through the viewing window to clean the chamber 130 in time.

[0043] Refer to Figures 2 to 4 As shown, it can be understood that the roller brush body 200 generally has a cylindrical structure. The roller brush body 200 is rotatably installed in the housing 100 and is located inside the chamber 130. The roller brush body 200 is arranged horizontally, and the rotation axis of the roller brush body 200 is arranged horizontally. The direction around the rotation axis of the roller brush body 200 is the circumferential direction of the roller brush body 200. Generally speaking, a motor is installed on the housing 100. The motor is connected to the roller brush body 200 through gears or belts, etc. to drive the roller brush body 200 to rotate to achieve floor cleaning.

[0044] Refer to Figures 2 to 4 As shown, it can be understood that, in order to be able to clean the floor, a plurality of wool strips 240 and a plurality of leather strips 250 are installed on the roller brush body 200. The wool strips 240 and the leather strips 250 respectively extend along the rotation axis direction of the roller brush body 200 in a spiral manner on the circumferential wall of the roller brush body 200, and both the wool strips 240 and the leather strips 250 protrude from the circumferential wall of the roller brush body 200 in the radial direction of the roller brush body 200. The plurality of wool strips 240 are arranged at equal intervals in the circumferential direction of the roller brush body 200. The plurality of leather strips 250 are arranged at equal intervals in the circumferential direction of the roller brush body 200, and the wool strips 240 and the leather strips 250 are arranged alternately in the circumferential direction of the roller brush body 200.

[0045] Refer to Figure 3As shown, it can be understood that a plurality of mounting grooves 230 are provided on the peripheral wall of the brush roller body 200. The cross-section of the mounting groove 230 is an inverted T shape, and the mounting groove 230 extends in a spiral manner along the rotation axis direction of the brush roller body 200. Plug-in portions are provided at the roots of the wool strips 240 and the leather strips 250. Therefore, the plug-in portions of the wool strips 240 and the leather strips 250 can be inserted into the mounting grooves 230 respectively from one end of the brush roller body 200 along the rotation axis direction to fix the wool strips 240 and the leather strips 250.

[0046] Referring to Figure 3 As shown, it can be understood that when the vacuum cleaner works, both the wool strips 240 and the leather strips 250 at least partially extend downward out of the opening 111 and contact the floor to clean the floor, facilitating the suction of dust, debris, etc. on the floor. Among them, the wool strips 240 are used to lift fine particulate matters such as dust or long and thin filamentous matters such as hair, and the leather strips 250 can scrape off the debris stuck to the floor.

[0047] It can be understood that the leather strips 250 are usually configured as rubber parts and have a certain elasticity. During the operation of the vacuum cleaner, when the brush roller body 200 rotates and winds around long and thin filamentous matters such as hair, the long and thin filamentous matters such as hair are wound around the plurality of leather strips 250, and the plurality of leather strips 250 can support the long and thin filamentous matters such as hair, reducing the friction force between the long and thin filamentous matters such as hair and the brush roller body 200 and preventing the long and thin filamentous matters such as hair from tightly winding around the brush roller body 200. At the same time, during the rotation of the brush roller body 200, the resistance of the long and thin filamentous matters such as hair moving along the rotation axis direction of the brush roller body 200 can be reduced. Under the action of suction, it is easy for the long and thin filamentous matters such as hair to move along the rotation axis direction of the brush roller body 200 so as to suck away the long and thin filamentous matters such as hair.

[0048] Referring to Figures 2 to 4 As shown, it can be understood that a collection area 210 is provided on the outer peripheral wall of the brush roller body 200 for collecting long and thin filamentous matters such as hair, that is, during the operation of the vacuum cleaner, the long and thin filamentous matters such as hair are concentrated in the collection area 210. Specifically, the collection area 210 can be a groove structure, a pit structure, etc. provided on the outer peripheral wall of the brush roller body 200, that is, the collection area 210 is recessed along the radial direction of the brush roller body 200 towards the rotation axis of the brush roller body 200.

[0049] It can be understood that the collection area 210 is located at one end of the wool strips 240 and the leather strips 250 along the rotation axis direction of the brush roller body 200. As the brush roller body 200 rotates, the spirally extending leather strips 250 can, to a certain extent, guide the long and thin filamentous matters such as hair wound around the plurality of leather strips 250 into the collection area 210 so as to concentrate the long and thin filamentous matters such as hair wound around the brush roller body 200 in the collection area 210.

[0050] Referring to Figure 2 and Figure 3As shown, it can be understood that the housing 100 is provided with a suction port 140. The suction port 140 communicates with the chamber 130 and is located on one side in the radial direction of the roller brush body 200. Generally speaking, the suction port 140 is connected to a suction motor to suck dust, debris, etc. in the chamber 130 into the trash collection box of the vacuum cleaner through the suction port 140. The collection area 210 is arranged corresponding to the suction port 140, that is, the collection area 210 is located at one end of the suction port 140 along the center line direction. When the vacuum cleaner works, a negative pressure is formed at the suction port 140. Under the action of the negative pressure, the slender filaments such as hair wound around a plurality of leather strips 250 can move along the rotation axis direction of the roller brush body 200 into the collection area 210. That is to say, the suction force at the suction port 140 can drive the slender filaments such as hair to move into the collection area 210.

[0051] Referring to Figure 2 and Figure 3 As shown, it can be understood that the cleaning component 300 is installed in the housing 100 and is located in the chamber 130. Specifically, the cleaning component 300 can be structures such as a cutter, a scraper, a blade, a comb tooth, etc., which can scrape off or cut off the slender filaments such as hair (or other winding objects) in the collection area 210. The cleaning component 300 can be installed on the base 110 or the upper cover 120. Generally speaking, the housing 100 is a plastic part, and the cleaning component 300 can be a metal part. The metal cleaning component 300 is installed on the housing 100 by screws or bonded to the housing 100. The cleaning component 300 can also be a plastic part, and the plastic cleaning component 300 and the housing 100 are of an integrally formed structure, which is convenient for processing. Of course, the cleaning component 300 can also be installed on the base 110 or the upper cover 120 in a radially movable and telescopic manner along the roller brush body 200.

[0052] Referring to Figure 2 and Figure 5 As shown, it can be understood that a blade part 310 is provided at one end of the cleaning component 300 facing the roller brush body 200. The length direction of the blade part 310 is parallel to the rotation axis of the roller brush body 200, and the blade part 310 can scrape off or cut off the slender filaments such as hair. Specifically, when the slender filaments such as hair are concentrated in the collection area 210 and rotate with the roller brush body 200, the blade part 310 can extend into the collection area 210 to scrape off or cut off the slender filaments such as hair.

[0053] Therefore, when the vacuum cleaner works, the brush roller body 200 rotates to clean dust, debris, etc. on the floor. Among them, long and thin filaments such as hair are wound around a plurality of leather strips 250. Under the guiding action of the leather strips 250 and the suction force at the suction port 140, the long and thin filaments such as hair move along the rotation axis direction of the brush roller body 200 to the collection area 210. Thus, the long and thin filaments such as hair wound around the brush roller body 200 can be concentrated in the collection area 210. As the brush roller body 200 rotates, the blade portion 310 of the cleaning component 300 can scrape off or cut the long and thin filaments such as hair in the collection area 210, playing an active anti-winding role. Therefore, it can prevent the long and thin filaments such as hair from being wound around the brush roller body 200 for a long time, and the anti-winding effect is good. Since the collection area 210 is arranged corresponding to the suction port 140, the long and thin filaments such as hair that are scraped off or cut are directly sucked away by the suction port 140, without the need for the user to clean up later, improving the user experience. Furthermore, it can prevent the long and thin filaments such as hair from affecting the rotation of the brush roller body 200, enabling the brush roller body 200 to work normally, which is beneficial to improving the cleaning efficiency. In addition, during the process of cleaning the long and thin filaments such as hair wound around the brush roller body 200, it is achieved by the cooperation of the cleaning component 300 and the collection area 210, avoiding the drawbacks of generating noise and damaging the leather strips 250 when scraping off the long and thin filaments such as hair directly from the leather strips 250 in the prior art. Thus, it can reduce noise and reduce the friction on the leather strips 250, which is beneficial to improving the service life of the leather strips 250.

[0054] Referring to Figure 2 As shown, it can be understood that the collection area 210 is located in the middle of the brush roller body 200 along the rotation axis direction. That is to say, the collection area 210 divides the brush roller body 200 into two equal parts on average. A plurality of wool strips 240 are evenly divided into two groups and are respectively arranged on the two parts of the brush roller body 200. Similarly, a plurality of leather strips 250 are evenly divided into two groups and are respectively arranged on the two parts of the brush roller body 200. The spiral directions of the wool strips 240 and the leather strips 250 on the same side of the collection area 210 along the rotation axis direction of the brush roller body 200 are the same, and the spiral directions of the wool strips 240 (or leather strips 250) on both sides of the collection area 210 along the rotation axis direction of the brush roller body 200 are opposite. Correspondingly, the suction port 140 is arranged corresponding to the middle position on the brush roller body 200 along the rotation axis direction. Therefore, the long and thin filaments such as hair wound around the two parts of the brush roller body 200 can move towards the collection area 210 at the middle position simultaneously, which is beneficial to improving the efficiency of cleaning the long and thin filaments such as hair.

[0055] Referring to Figures 2 to 4As shown, it can be understood that the collection area 210 surrounds the rotation axis of the roller brush body 200, that is, the collection area 210 is set as an annular groove, which is arranged along the circumference of the roller brush body 200 and is recessed toward the rotation axis of the roller brush body 200, so that the roller brush body 200 rotates in a balanced manner to avoid vibration and noise. The blade 310 of the cleaning component 300 remains extended into the annular groove. Therefore, as the roller brush body 200 rotates, the blade 310 continuously scrapes or cuts off the hair and other slender filaments in the annular groove, further improving the efficiency of cleaning hair and other slender filaments, and has a good anti-entanglement effect.

[0056] It can be understood that the collection area 210 can also be composed of a plurality of arcuate grooves, which are arranged around the rotation axis of the roller brush body 200. The arc corresponding to the edge of the arcuate groove can be a minor arc or a major arc. The plurality of arcuate grooves are arranged at equal intervals along the circumference of the roller brush body 200. Correspondingly, the cleaning component 300 is configured to be movable and retractable along the radial direction of the roller brush body 200. For example, the cleaning component 300 is connected with components such as springs and cylinders. When the arcuate groove corresponds to the position of the cleaning component 300 in the radial direction of the roller brush body 200, the blade 310 of the cleaning component 300 extends into the arcuate groove to scrape off or cut off slender filaments such as hair. When the arcuate groove and the cleaning component 300 are misaligned, the cleaning component 300 retracts in the opposite direction or abuts against the outer wall of the roller brush body 200 to avoid interference between the cleaning component 300 and the roller brush body 200 and affect the rotation of the roller brush body 200.

[0057] Reference Figures 2 to 4 As shown, it can be understood that the collection area 210 is set as an annular groove, and the annular groove has a bottom wall 211 on the side facing the rotation axis of the roller brush body 200. Generally speaking, the bottom wall 211 is in a circular ring shape, that is, the cross section of the roller brush body 200 at the annular groove is circular, and the cross section here is a plane perpendicular to the rotation axis of the roller brush body 200. When hair and other slender filaments are wound around the annular groove, as the roller brush body 200 rotates, the hair and other slender filaments are easy to slip and do not rotate with the roller brush body 200, resulting in the blade 310 being unable to scrape off or cut off the hair and other slender filaments, resulting in the inability to clean the hair and other slender filaments.

[0058] For this purpose, refer to Figures 2 to 4As shown, it can be understood that the roller brush body 200 is provided with an anti-skid portion 220, and the anti-skid portion 220 is located in the collection area 210. Specifically, the anti-skid portion 220 includes two side walls, and the two side walls are arranged at intervals along the rotation axis direction of the roller brush body 200. In the direction perpendicular to and toward the rotation axis of the roller brush body 200, the distance between the two side walls decreases until the two side walls are connected, that is, the anti-skid portion 220 is a V-shaped groove, and the small end of the V-shaped groove faces the rotation axis of the roller brush body 200. The notch width of the V-shaped groove is greater than the notch width of the annular groove, and along the radial direction of the roller brush body 200, the depth of the V-shaped groove is greater than the depth of the annular groove. Therefore, The edge of the cross section of the roller brush body 200 at the collection area 210 has a straight line segment instead of a full circle, that is, the bottom wall 211 has edges and corners, which can increase the resistance of the hair and other slender filaments to the rotation of the roller brush body 200, prevent the hair and other slender filaments wound around the collection area 210 from slipping, and make the hair and other slender filaments rotate with the roller brush body 200, so that the blade 310 can scrape off or cut the hair and other slender filaments, prevent the hair and other slender filaments from being entangled on the roller brush body 200 for a long time, and the anti-entanglement effect is good.

[0059] Reference Figures 2 to 4 As shown, it can be understood that the roller brush body 200 is provided with multiple anti-slip parts 220, that is, multiple V-shaped grooves are provided in the collection area 210, and the multiple V-shaped grooves are arranged at equal intervals along the circumference of the roller brush body 200, so that there are multiple straight line segments on the edge of the cross section of the roller brush body 200 at the collection area 210, which further increases the resistance of the hair and other slender filaments to the rotation of the roller brush body 200, and prevents the hair and other slender filaments arranged around the collection area 210 from slipping. For example, the roller brush body 200 is provided with two V-shaped grooves located in the collection area 210, and the two V-shaped grooves are symmetrical about the center of the rotation axis of the roller brush body 200, which will not be repeated here.

[0060] It can be understood that the anti-slip portion 220 can also be a square groove, and the groove wall of the square groove on the side facing the rotation axis of the roller brush body 200 is a plane, that is, at least one plane is formed on the bottom wall 211 of the annular groove. Alternatively, the anti-slip portion 220 is a plane arranged on the bottom wall 211 of the annular groove. Therefore, it is also possible to make at least one straight line segment exist on the edge of the cross section of the roller brush body 200 at the collection area 210, so as to increase the resistance of the hair and other slender filaments to the rotation of the roller brush body 200, and prevent the hair and other slender filaments arranged around the collection area 210 from slipping.

[0061] Reference Figure 8As shown, it can be understood that the cross-section of the roller brush body 200 at the collection area 210 is a polygon, generally a regular polygon. That is to say, the bottom wall 211 of the collection area 210 is composed of multiple planes connected in sequence along the circumferential direction of the roller brush body 200. It can also be understood that a plurality of anti-slip portions 220 connected in sequence along the circumferential direction of the roller brush body 200 are provided on the bottom wall 211 of the collection area 210. Therefore, the resistance of relatively thin and long filaments such as hair to the rotation of the roller brush body 200 can be further increased, preventing the relatively thin and long filaments such as hair wound around the collection area 210 from slipping. Generally speaking, the number of sides of the polygon does not exceed five to ensure that the resistance between the relatively thin and long filaments such as hair and the roller brush body 200 can prevent the relatively thin and long filaments such as hair from slipping.

[0062] Referring to Figure 9 As shown, it can be understood that the cross-section of the roller brush body 200 at the collection area 210 can also be an ellipse, so that the bottom wall 211 has a portion protruding in the radial direction of the roller brush body 200. When the cross-section of the roller brush body 200 at the collection area 210 is an ellipse, the rotational resistance of the roller brush body 200 to relatively thin and long filaments such as hair is greater than that when it is circular, preventing the relatively thin and long filaments such as hair wound around the collection area 210 from slipping.

[0063] Referring to Figure 3As shown, it can be understood that the collection area 210 is arranged as an annular groove. One side of the annular groove facing the rotation axis of the brush roller body 200 has a bottom wall 211. Since anti-slip portions 220 such as V-shaped grooves and square groove structures can be arranged in the collection area 210, generally speaking, both sides of the annular groove along the rotation axis direction of the brush roller body 200 have groove walls. Here, the bottom wall 211 is the wall body part located between the reference planes where the two groove walls are located. Since the cross-section of the bottom wall 211 can be circular, elliptical or polygonal, etc., the distances from the bottom wall 211 to the cutting edge 310 are not equal. Define the maximum distance between the bottom wall 211 and the rotation axis of the brush roller body 200 as R, and the minimum distance between the cutting edge 310 and the rotation axis of the brush roller body 200 as L, satisfying: 0 ≤ (L - R) ≤ 3 mm. That is to say, during the rotation of the brush roller body 200, there is a minimum distance between the cutting edge 310 and the bottom wall 211, which is 0 to 3 mm. When L - R = 0 mm, that is, during the rotation of the brush roller body 200, the bottom wall 211 and the cutting edge 310 contact at least once, or the cutting edge 310 always contacts the bottom wall 211, ensuring that the cutting edge 310 can completely scrape off or cut off hair and other slender filaments on the collection area 210, realizing the cleaning of hair and other slender filaments; making L - R ≥ 0 mm can prevent the cutting edge 310 from interfering with the rotation of the brush roller body 200. Making L - R ≤ 3 mm, that is, during the rotation of the brush roller body 200, the minimum distance between the bottom wall 211 and the cutting edge 310 will not exceed 3 mm, to ensure that the cutting edge 310 will not be too far from the bottom wall 211, preventing the cutting edge 310 from being unable to scrape off or cut off hair and other slender filaments, effectively improving the anti-winding effect. For example, L - R = 1 mm, L - R = 2 mm or L - R = 3 mm, etc.

[0064] It can be understood that to further improve the anti-winding effect, 0 ≤ (L - R) ≤ 1 mm. This will not be elaborated here.

[0065] Referring to Figure 3 and Figure 5 As shown, it can be understood that the cleaning component 300 is provided with two cutting edges 310. The length directions of the two cutting edges 310 are both parallel to the rotation axis of the brush roller body 200, that is, the length directions of the cutting edges 310 are both parallel to the bottom wall 211 of the collection area 210, and the two cutting edges 310 are arranged at intervals along the circumferential direction of the brush roller body 200. Therefore, during the rotation of the brush roller body 200 with hair and other slender filaments, both of the two cutting edges 310 can scrape off or cut off the hair and other slender filaments, which is beneficial to improving the efficiency and reliability of cleaning hair and other slender filaments, so as to further improve the anti-winding effect. Of course, it can be understood that the cleaning component 300 can also be provided with three, four or more cutting edges 310. This will not be elaborated here.

[0066] Referring to Figure 7As shown, it can be understood that the cleaning component 300 may also be provided with only one cutting edge 310, which will not be elaborated here.

[0067] Referring to Figure 6 As shown, it can be understood that the cutting edge 310 is provided with a plurality of teeth 311. One end of the teeth 311 facing the roller brush body 200 is a pointed part, and the two side edges of the teeth 311 along the rotation axis direction of the roller brush body 200 are sharp edges. The plurality of teeth 311 are arranged at equal intervals along the rotation axis direction of the roller brush body 200, that is, the cutting edge 310 is a comb-like structure. The teeth 311 can penetrate into slender filaments such as hair, so as to tear off and cut the slender filaments such as hair, preventing the slender filaments such as hair from being wound around the roller brush body 200 for a long time, and having a good anti-winding effect.

[0068] The cleaning device according to the second aspect embodiment of the present invention includes the floor brush assembly according to the first aspect embodiment of the present invention. The cleaning device may be a vacuum cleaner, a floor washer, a sweeping robot, etc.

[0069] Since the cleaning device adopts the above-mentioned floor brush assembly, when the cleaning device works, the roller brush body 200 rotates to clean dust, debris, etc. on the floor. Among them, slender filaments such as hair are wound around a plurality of leather strips 250. Under the guiding action of the leather strips 250 and the suction force at the suction port 140, the slender filaments such as hair move along the rotation axis direction of the roller brush body 200 to the collection area 210, so that the slender filaments such as hair wound around the roller brush body 200 can be concentrated in the collection area 210. As the roller brush body 200 rotates, the cutting edge 310 of the cleaning component 300 can scrape off or cut the slender filaments such as hair in the collection area 210, thereby preventing the slender filaments such as hair from being wound around the roller brush body 200 for a long time, and having a good anti-winding effect. Since the collection area 210 is arranged corresponding to the suction port 140, the scraped or cut slender filaments such as hair are directly sucked away by the suction port 140, without the need for the user to clean up later, improving the user experience. Furthermore, it can prevent the slender filaments such as hair from affecting the rotation of the roller brush body 200, so that the roller brush body 200 can work normally, which is beneficial to improving the cleaning efficiency. In addition, in the process of cleaning the slender filaments such as hair wound around the roller brush body 200, it is realized by the cooperation of the cleaning component 300 and the collection area 210, avoiding the drawbacks of directly scraping off the slender filaments such as hair from the leather strips 250 by a comb in the prior art, which may generate noise and cause damage to the leather strips 250. Thus, the noise can be reduced and the friction on the leather strips 250 can be reduced, which is beneficial to improving the service life of the leather strips 250.

[0070] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
