[0002] When the roller brush in a traditional floor brush is in use, dust, debris and hair on the ground will come into contact with the cleaning strip on the surface of the roller brush and be swept toward the suction port opened on the floor brush housing, thereby sucking the dust and garbage into the vacuum device through the suction port.

[0003] However, during the cleaning process, the roller brush in the conventional vacuum cleaner floor brush is found to easily entangle hair on the roller brush surface, and as the roller brush rotates, the hair becomes more and more entangled, so that the hair is deeply embedded in the brush plate arranged outside the roller brush, making it difficult for the comb teeth to smoothly remove the deeply embedded hair.

[0048] Such as Figure 2-3As shown in the figure. In a preferred embodiment of the present application, a rotary brush 100 is provided, which includes a drum 110, a plurality of brush plates 120, a plurality of first scraping plates 130 and a plurality of second scraping plates 140. Among them, each brush plate 120, each first scraping plate 130 and each second scraping plate 140 correspond to each other one by one. Each brush plate 120 is arranged on the outer surface of the drum 110, and the brush plates 120 are arranged to extend from one end of the drum 110 towards the other end. Among them, each brush plate 120 includes a plurality of bristles, and each bristle is arranged perpendicular to the outer surface of the drum 110. The first scraping plate 130 and the second scraping plate 140 corresponding to one brush plate 120 are respectively arranged on both sides of the brush plate 120, and the extending directions of the first scraping plate 130 and the second scraping plate 140 are both parallel to the extending direction of the brush plate 120. Moreover, the end of the brush plate 120 facing away from the drum 110 is located between the end of the corresponding first scraping plate 130 facing away from the drum 110 and the outer surface of the drum 110. The distance between the end of the first scraping plate 130 facing away from the drum 110 and the end of the corresponding brush plate 120 facing away from the drum 110 takes any value from 0 mm to 0.5 mm. The end of the second scraping plate 140 facing away from the drum 110 is located between the end of the corresponding brush plate 120 facing away from the drum 110 and the outer surface of the drum 110. The distance between the end of the first scraping plate 130 facing away from the drum 110 and the end of the corresponding second scraping plate 140 facing away from the drum 110 takes any value from 1 mm to 2 mm. In particular, the first scraping plate 130 has flexibility and elasticity that can be bent in the direction towards the second scraping plate 140, and the second scraping plate 140 has flexibility and elasticity that can be bent in the direction away from the first scraping plate 130. For this rotary brush 100, the first scraping plate 130 and the second scraping plate 140 are respectively arranged on both sides of the brush plate 120, so that there is a height difference between the end of the first scraping plate 130 facing away from the drum 110 and the end of the second scraping plate 140 facing away from the drum 110, and the end of the brush plate 120 facing away from the drum 110 is located between the end of the first scraping plate 130 facing away from the drum 110 and the end of the second scraping plate 140 facing away from the drum 110. In this way, after the hair wound around the outer peripheral side of the rotary brush 100 forces the first scraping plate 130 to bend, a reverse supporting force is applied to the hair through the second scraping plate 140 to limit the hair from continuing to embed into the brush plate 120, prevent the hair from embedding too deep into the brush plate 120, and reduce the difficulty of removing the hair wound on the rotary brush 100 subsequently.

[0049] Specifically, the shape of the drum 110 is a cylinder, the brush plate 120 extends from one end of the cylinder to the other end, and the extending directions of the first scraper 130 and the second scraper 140 respectively arranged on both sides of the brush plate 120 are parallel to the extending direction of the brush plate 120. Among them, both the first scraper 130 and the second scraper 140 are long strip-shaped plate members, and their length directions are their extending directions. Moreover, the first scraper 130 has flexibility and bendability in the direction of facing or departing from the second scraper 140, and the second scraper 140 has flexibility and bendability in the direction of departing from or facing the first scraper 130, so that the first scraper 130 and the second scraper 140 can be bent and deformed when bound by the hair wound around the outer periphery of the roller brush 100, and after removing the hair wound around the outer periphery of the roller brush 100, both the first scraper 130 and the second scraper 140 can return to their original states under the action of their own elasticity. It should be noted that the extending direction of the brush plate 120 is the arrangement direction of each brush in the brush plate 120. In some embodiments, the numbers of the brush plate 120, the first scraper 130, and the second scraper 140 are all three, and the three brush plates 120 are equally spaced around the circumferential side of the drum 110, and the included angles between any two of the three brush plates 120 are all 120 degrees.

[0050] In some embodiments, one end of the first scraper 130 departing from the drum 110 and on the side of this end departing from the second scraper 140 is configured with a round chamfer, and this round chamfer is matched with the rotation direction of the drum 110, which can make the end of the first scraper 130 departing from the drum 110 better fit the ground.

[0051] As Figure 3 shown. In some embodiments, several mounting grooves 111 are formed on the surface of the drum 110, and each brush plate 120, the first scraper 130 corresponding to this brush plate 120, and the second scraper 140 corresponding to this brush plate 120 are all connected to the respective mounting grooves 111 in a one-to-one correspondence manner, and the extending direction of the mounting groove 111 is parallel to the extending direction of the corresponding brush plate 120. One side of the first scraper 130 located on one side of the brush plate 120 facing the drum 110 and one side of the second scraper 140 located on the other side of this brush plate 120 facing the drum 110 are connected to form a connection structure 150 that is cooperatively connected with the mounting groove 111.

[0052] Specifically, the cross-sectional shape of the mounting groove 111 and the cross-sectional shape of the connection structure 150 are both an inverted "T" - shaped structure, and the connection structure 150 is inserted into the mounting groove 111.

[0053] In some embodiments, the first scraper 130, the second scraper 140 and the connecting structure 150 on both sides of the same brush plate 120 are formed by bending a sheet of wear-resistant TPE (thermoplastic elastomer), and the brush plate 120 is clamped between the first scraper 130 and the second scraper 140.

[0054] In some embodiments, one end of each bristle of the brush plate 120 facing the drum 110 is fixedly connected to the side of the connection structure 150 away from the drum 110, and each bristle is located between the corresponding first scraper 130 and the second scraper 140, so that the bristle is connected to the connection structure 150 as a whole. In other embodiments, the brush plate 120 also includes a mounting plate (not shown in the figure), which is a long strip plate, which is installed in the connection structure 150, and one end of each bristle of the brush plate 120 facing the drum 110 is fixedly connected to the side of the mounting plate away from the drum 110.

[0055] In some embodiments, when the brush plate 120 extends from one end of the drum 110 to the other end, the brush plate 120 spirally extends around the circumference of the drum 110 , and the pitch of the spirally extended brush plate 120 is greater than 2.5 times the axial length of the drum 110 .

[0056] like Figure 2 In other embodiments, each brush plate 120 is composed of a first brush segment 121 and a second brush segment 122, each first scraper 130 is composed of a first scraper segment 131 and a second scraper segment 132, each second scraper 140 is composed of a third scraper segment 141 and a fourth scraper segment 142, the roller 110 includes a first end 112 and a second end 113, the first brush segment 121, the first scraper segment 131 and the third scraper segment 141 are all extended from the first end 112 of the roller 110 toward the second end 113, the second brush segment 122, the second scraper segment 132 and the fourth scraper segment 142 are all extended from the second end 113 of the roller 110 toward the first end 112, and the ends of the first brush segment 121 and the second brush segment 122 facing each other are staggered and overlapped, the ends of the first scraper segment 131 and the second scraper segment 132 facing each other are staggered and overlapped, and the ends of the third scraper segment 141 and the fourth scraper segment 142 facing each other are staggered and overlapped.

[0057] Specifically, the overlapping parts of the opposite-facing ends of the first brush section 121 and the second brush section 122, the overlapping parts of the opposite-facing ends of the first scraping section 131 and the second scraping section 132, and the overlapping parts of the opposite-facing ends of the third scraping section 141 and the fourth scraping section 142 all increase the contact area of the brush plate 120, the first scraper 130, and the second scraper 140 with the outside in the overlapping area, that is, increase the contact area with the ground, making the pressure of the rolling brush 100 more evenly distributed during operation. Moreover, the above-mentioned cross-shaped end settings effectively eliminate the concentrated stress points in the tip area of the "V"-shaped cleaning strips on the surface of the traditional rolling brush compared with the "V"-shaped cleaning strips on the surface of the traditional rolling brush, thereby reducing the uneven force on the rolling brush 100 during the cleaning process. Further, compared with the "V"-shaped design, the cross-shaped end setting has no obvious sharp corners, which can avoid excessive local pressure generated when the rolling brush 100 rotates and avoid excessive force on the local area of the rolling brush 100.

[0058] Further, in this embodiment, both the first brush section 121 and the second brush section 122 extend spirally around the outer peripheral side of the drum 110, the length of the pitch is greater than 2.5 times the axial length of the drum 110, and the spiral directions of the first brush section 121 and the second brush section 122 are set in opposite directions. Both the first scraping section 131 and the second scraping section 132 extend spirally around the outer peripheral side of the drum 110, the length of the pitch is greater than 2.5 times the axial length of the drum 110, and the spiral directions of the first scraping section 131 and the second scraping section 132 are set in opposite directions. Both the third scraping section 141 and the fourth scraping section 142 extend spirally around the outer peripheral side of the drum 110, the length of the pitch is greater than 2.5 times the axial length of the drum 110, and the spiral directions of the third scraping section 141 and the fourth scraping section 142 are set in opposite directions. Among them, the spiral directions of the first brush section 121, the first scraping section 131, and the third scraping section 141 are set in the same direction, and the spiral directions of the second brush section 122, the second scraping section 132, and the fourth scraping section 142 are set in the same direction. After the rolling brush 100 rotates in the spiral direction of the first brush section 121, the hair in contact with the rolling brush 100 will move towards the middle part of the axial direction of the drum 110 under the combined action of the brush plate 120, the first scraper 130, and the second scraper 140 to collect the hair in this area, thereby reducing the probability of hair detaching from the rolling brush 100.

[0059] Such as Figure 1 And Figure 4As shown. As shown in the figure, in another preferred embodiment of the present application, a floor brush 200 is provided. The floor brush 200 is applicable to the above-mentioned roller brush 100. Moreover, the floor brush 200 further includes a housing 210, a driving mechanism, and a comb tooth plate 220. Among them, the housing 210 includes a working plane 211. A receiving cavity 230 is formed at the working plane 211. The roller brush 100 is arranged in the receiving cavity 230 in a manner of rotating around the axis of the drum 110. And, a part of the outer surface of the roller brush 100 protrudes from the working plane 211.

[0060] Specifically, the working plane 211 is a plane on the outer side of the housing 210. During operation, the working plane 211 is in contact with the ground. The side of the roller brush 100 facing away from the housing 210 protrudes from the working plane 211 to contact the ground, so that the end of the brush plate 120 facing away from the drum 110 and the end of the first scraper 130 facing away from the drum 110 can both contact the ground. It can be understood that according to the spacing difference between the end of the first scraper 130 facing away from the drum 110 and the corresponding end of the brush plate 120 facing away from the drum 110, and the spacing difference between the end of the first scraper 130 facing away from the drum 110 and the corresponding end of the second scraper 140 facing away from the drum 110, and that the end of the brush plate 120 facing away from the drum 110 is located between the end of the corresponding first scraper 130 facing away from the drum 110 and the end of the brush plate 120 facing away from the drum 110, and the end of the second scraper 140 facing away from the drum 110 is located between the end of the corresponding brush plate 120 facing away from the drum 110 and the outer surface of the drum 110, the spacing between the end of the second scraper 140 facing away from the drum 110 and the end of the brush plate 120 facing away from the drum 110 is between 0.5 mm and 2 mm. This end spacing can reduce the probability of the second scraper 140 contacting the ground during the operation of the roller brush 100.

[0061] A driving mechanism (not shown in the figure), the output end of the driving mechanism is transmitted to the end of the roller 110 to drive the roller 110 to rotate, and the end of the roller 110 is also constructed with a structure compatible with the driving end to ensure that it can rotate therewith, and the other end of the roller 110 is also rotatably connected relative to the inner wall of the accommodating chamber 230, and a positioning member is provided at the inner wall of the accommodating chamber 230 on the opposite side of the driving end of the driving mechanism, and the positioning member is aligned with the driving end. The other end of the roller 110 away from the driving end is rotatably connected to the inner wall of the accommodating chamber 230 through the positioning member, and the cooperation between the positioning member and the driving end only limits the axial movement and radial movement of the roller 110, so that the roller 110 can only rotate, and when the roller 110 is installed in the accommodating chamber 230 through the driving end and the positioning member, the axis of the roller 110 coincides with the line connecting the center of the driving end and the center of the positioning member. It should be noted that the rotation direction of the driving mechanism is limited. In order to cooperate with the first scraper 130 and the second scraper 140 respectively distributed on both sides of the brush plate 120 to limit the hair from further embedding into the brush plate 120, when the rotation direction of the roller 110 under the action of the driving mechanism is specifically to the first scraper 130 and the second scraper 140 on both sides of a brush plate 120, the rotation direction of the roller 110 should be from the second scraper 140 to the first scraper 130.

[0062] The comb plate 220 is in the shape of an elongated strip as a whole, and its length direction is parallel to the axial direction of the drum 110. When the working plane 211 is in contact with the ground, the comb plate 220 is located obliquely above the drum 110, and the side of the comb plate 220 facing the drum 110 is constructed as a comb structure, and the angle between the extended length direction of the comb structure and the vertical or horizontal direction is between 30 degrees and 60 degrees, and the comb structure is configured so that when the roller brush 100 rotates, the comb structure and the brush plate 120 interfere with each other to remove the hair embedded in the brush plate 120. It can be understood that the interference length between the comb structure and the brush plate 120 is between 0.5mm and 2.5mm, which disrupts the force of hair entanglement so as to remove the hair embedded in the brush plate 120.

[0063] In some embodiments, the accommodating chamber 230 is configured with a suction port on the front side of the rotation path of the roller brush 100 so that the hair removed from the roller brush 100 can be sucked away in real time during operation.

[0064] In some embodiments, a third scraper 240 is also provided in the accommodating cavity 230 where the comb plate 220 is provided. The third scraper 240 is arranged in a parallel manner on one side of the comb plate 220. The third scraper 240 is preferably made of a hard material with low elasticity and deformation ability. It is overall in a long strip shape with its width extending in the direction toward the roller 110. There is interference between the extension length of the third scraper 240 and the brush plate 120 to perform secondary cleaning of the roller brush 100.

[0065] The above content described in this specification is only an example illustration of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claims, and shall fall within the protection scope of the present utility model.
