[0002] At present, cleaning equipment such as vacuum cleaners have greatly facilitated household cleaning work and reduced people’s housework intensity.

[0003] However, the roller brush of the vacuum cleaner is often entangled with hair and slender filaments, which hinder the rotation of the roller brush and affect the dust removal effect. In addition, due to the rotation of the roller brush, the hair and slender filaments are tightly entangled on the roller brush, making cleaning more difficult. Utility Model Content

[0004] The utility model aims to at least solve or improve the technical problem that the roller brush of the cleaning equipment in the prior art is difficult to clean.

[0005] To this end, a first aspect of the utility model provides a roller brush.

[0006] A second aspect of the utility model provides a cleaning device.

[0007] In view of this, according to the first aspect of the utility model, the utility model proposes a roller brush, comprising: a roller; a cleaning part, arranged on the peripheral side of the roller brush; a support member, arranged on the peripheral side of the roller, at least on one side of the cleaning part; wherein the height of the cleaning part protruding from the roller is lower than the height of the support member protruding from the roller.

[0008] The roller brush provided by the utility model comprises a roller, a cleaning part and a supporting member. The cleaning part and the supporting member are both arranged on the peripheral side of the roller, and the supporting member is at least located on one side of the cleaning part.

[0009] The height of the support member protruding from the drum is greater than the height of the cleaning part protruding from the drum. Therefore, when the drum rotates for cleaning, the support member protrudes from the cleaning part, thereby reducing the possibility of hair or slender filaments being embedded in the cleaning part.

[0010] In addition, the roller brush in the above technical solution provided by the utility model may also have the following additional technical features:

[0011] In some embodiments, optionally, the height of the support member protruding from the drum is a first height, and the height of the cleaning portion protruding from the drum is a second height; wherein the difference between the first height and the second height is greater than 0 and less than or equal to 2 mm.

[0012] In this embodiment, the height of the support member protruding from the drum is a first height, the height of the cleaning part protruding from the drum is a second height, and the difference between the first height and the second height is greater than 0 and less than or equal to 2 mm.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0053] Refer to the following Figures 1 to 4 To describe the roller brush 100 and the cleaning device provided according to some embodiments of the present invention.

[0054] like Figures 1 to 4 As shown, according to the first aspect of the utility model, the utility model provides a roller brush 100, which is used for cleaning equipment. The roller brush 100 includes a roller 110, a cleaning portion 120 and a support member 130. The cleaning portion 120 and the support member 130 are both arranged on the circumference of the roller 110. The cleaning portion 120 extends in a spiral shape from one end to the other end of the roller 110. Along the circumference of the roller 110, the support members 130 are respectively located on both sides of the cleaning portion 120.

[0055] The support member 130 extends in a spiral shape from one end to the other end of the drum 110 , wherein the cleaning portion 120 and the support member 130 are arranged substantially in parallel.

[0056] The roller brush 100 provided in the present invention comprises a roller 110 , a cleaning portion 120 and a support member 130 . The cleaning portion 120 and the support member 130 are both arranged on the circumference of the roller 110 , and the support member 130 is at least located on one side of the cleaning portion 120 .

[0057] The height of the support member 130 protruding from the drum 110 is greater than the height of the cleaning portion 120 protruding from the drum 110. Therefore, when the drum 110 rotates for cleaning, the drum 110 rotates. Since the support member 130 protrudes from the cleaning portion 120, the possibility of hair or slender filaments being embedded in the cleaning portion 120 can be reduced.

[0058] like Figure 2 As shown, in some embodiments, optionally, the height of the support member 130 protruding from the drum 110 is a first height h, that is, along the radial direction of the drum 110, the height of the support member 130 protruding from the drum 110 is the first height h, and the height of the cleaning portion 120 protruding from the drum 110 is a second height b, that is, along the radial direction of the drum 110, the height of the cleaning portion 120 protruding from the drum 110 is the second height b, wherein the difference a between the first height h and the second height b is greater than 0 and less than or equal to 2 mm.

[0059] In this embodiment, the height of the support member 130 protruding from the drum 110 is a first height h, and the height of the cleaning part 120 protruding from the drum 110 is a second height b. The difference a between the first height h and the second height b is greater than 0 and less than or equal to 2 mm. This ensures the cleaning effect of the cleaning part 120 while reducing the possibility of hair or slender filaments being embedded in the cleaning part 120, thereby reducing the difficulty of cleaning the roller brush 100.

[0060] Specifically, the difference a between the first height h and the second height b may be equal to 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0061] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the support member 130 includes a first support member 132 and a second support member 134, and at least one of the first support member 132 and the second support member 134 protrudes from the drum 110 at a height higher than the height of the cleaning part 120 protruding from the drum 110; along the cleaning rotation direction of the roller brush 100, the first support member 132 is located on the front flow side of the cleaning part 120, and the second support member 134 is located on the rear flow side of the cleaning part 120.

[0062] In this embodiment, the roller brush 100 includes a roller 110, a cleaning portion 120, a first support member 132 and a second support member 134. The cleaning portion 120, the first support member 132 and the second support member 134 are all arranged on the circumference of the roller 110. The cleaning portion 120 extends in a spiral shape from one end to the other end of the roller 110. Along the circumference of the roller 110, the first support member 132 and the second support member 134 are respectively located on both sides of the cleaning portion 120.

[0063] The first support member 132 extends in a spiral shape from one end to the other end of the drum 110 , and the second support member 134 extends in a spiral shape from one end to the other end of the drum 110 , wherein the cleaning portion 120 , the first support member 132 , and the second support member 134 are arranged substantially in parallel.

[0064] Among them, Figure 4 As shown, the height of the first support member 132A protruding from the drum 110 is greater than the height of the cleaning portion 120A protruding from the drum 110. Figure 4 As shown, the height of the second support member 134B protruding from the drum 110 is greater than the height of the cleaning portion 120B protruding from the drum 110, or as shown in FIG. Figure 2 and Figure 3 As shown, the heights of the first support member 132 and the second support member 134 protruding from the drum 110 are both greater than the height of the cleaning portion 120 protruding from the drum 110 .

[0065] like Figure 4 As shown, the height of the first support member 132A protruding from the drum 110 is greater than the height of the cleaning portion 120A protruding from the drum 110. Therefore, when the drum 110 rotates for cleaning, the drum 110 rotates. Since the first support member 132 protrudes from the cleaning portion 120, the possibility of hair or slender filaments being embedded in the cleaning portion 120 is reduced.

[0066] or Figure 4 As shown, the height of the second support member 134B protruding from the drum 110 is greater than the height of the cleaning portion 120B protruding from the drum 110.

[0067] or Figure 2 and Figure 3 As shown, the height of the first support member 132 and the second support member 134 protruding from the drum 110 is greater than the height of the cleaning portion 120 protruding from the drum 110. Therefore, when the drum 110 rotates for cleaning, the drum 110 rotates. Since the second support member 134 protrudes from the cleaning portion 120, the possibility of hair or slender filaments being embedded in the cleaning portion 120 is reduced.

[0068] The cleaning portion 120 has a first support member 132 and a second support member 134 on both sides, so the first support member 132 and the second support member 134 will support the hair or slender filaments to reduce the depth of the hair or slender filaments embedded in the cleaning portion 120, thereby reducing the difficulty of cleaning the roller brush 100.

[0069] Among them, multiple groups of cleaning parts 120, first support members 132 and second support members 134 can be arranged on the drum 110, and one group of cleaning parts 120, first support members 132 and second support members 134 includes one cleaning part 120, one first support member 132 and one second support member 134.

[0072] In this embodiment, the height of the first support member 132A protruding from the roller 110 is a first height h1, the height of the cleaning portion 120A protruding from the roller 110 is a second height b1, and the difference a1 between the first height h1 and the second height b1 is greater than 0 and less than or equal to 2 mm. This ensures the cleaning effect of the cleaning portion 120 while reducing the possibility of hair or slender filaments being embedded in the cleaning portion 120, thereby reducing the difficulty of cleaning the roller brush 100.

[0073] Specifically, the difference a1 between the first height h1 and the second height b1 may be equal to 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0074] like Figure 4As shown, in some embodiments, optionally, the height of the second support member 134B protruding from the roller 110 is a first height h2, that is, along the radial direction of the roller 110, the height of the second support member 134B protruding from the roller 110 is a first height h2, and the height of the cleaning portion 120B protruding from the roller 110 is a second height b2, that is, along the radial direction of the roller 110, the height of the cleaning portion 120B protruding from the roller 110 is a second height b2, wherein the difference a2 between the first height h2 and the second height b2 is greater than 0 and less than or equal to 2 mm.

[0075] In this embodiment, the height of the second support member 134B protruding from the roller 110 is a first height h2, and the height of the cleaning portion 120B protruding from the roller 110 is a second height b2. The difference a2 between the first height h2 and the second height b2 is greater than 0 and less than or equal to 2 mm. This ensures the cleaning effect of the cleaning portion 120 while reducing the possibility of hair or slender filaments being embedded in the cleaning portion 120, thereby reducing the difficulty of cleaning the roller brush 100.

[0076] like Figure 2 As shown, in some embodiments, optionally, the heights of the first support member 132 and the second support member 134 protruding from the drum 110 are both a first height h, that is, along the radial direction of the drum 110, the heights of the first support member 132 and the second support member 134 protruding from the drum 110 are the first height h, and the height of the cleaning portion 120 protruding from the drum 110 is a second height b, that is, along the radial direction of the drum 110, the height of the cleaning portion 120 protruding from the drum 110 is the second height b, wherein the difference a between the first height h and the second height b is greater than 0 and less than or equal to 2 mm.

[0077] In this embodiment, the heights of the first support member 132 and the second support member 134 protruding from the drum 110 are both a first height h, the height of the cleaning portion 120 protruding from the drum 110 is a second height b, and the difference a between the first height h and the second height b is greater than 0 and less than or equal to 2 mm, thereby ensuring the cleaning effect of the cleaning portion 120 while reducing the possibility of hair being stuck in the cleaning portion 120 or slender filaments being embedded in the cleaning portion 120, thereby reducing the difficulty of cleaning the roller brush 100.

[0078] like Figure 3 As shown, in some embodiments, optionally, when the roller brush 100 rotates to clean the surface to be cleaned, the support member 130 passes through the surface to be cleaned first, and then the cleaning portion 120 passes through the surface to be cleaned, and, with the end of the support member 130 facing away from the drum 110 as a reference, the length of the gap between the cleaning portion 120 and the support member 130 is a first length d, and the height of the support member 130 protruding from the drum 110 is a first height h, and the first height h is less than the first length d.

[0079] In this embodiment, along the cleaning rotation direction e of the roller brush 100, with the end of the support member 130 away from the roller brush 100 as a reference, the length of the gap between the cleaning portion 120 and the support member 130 is a first length d, the first length d is an arc structure at one end, the radius of the first length d is the sum of the radius of the drum 110 and the length of the support member 130 protruding from the drum 110, one end of the first length d is an end point of the support member 130 away from the drum 110 and toward the cleaning portion 120, and the other end of the first length d is an end point of the cleaning portion 120 away from the drum 110 and toward the support member 130.

[0080] The height of the support member 130 protruding from the drum 110 is a first height h, and the first height h is less than the first length d. After the support member 130 contacts and tilts over the surface to be cleaned, the cleaning portion 120 can also be fully separated from the surface to be cleaned, thereby ensuring the cleaning effect of the cleaning portion 120, avoiding the cleaning portion 120 and the support member 130 being too close to each other, resulting in the cleaning portion 120 being unable to fully contact the surface to be cleaned, and ensuring the effect of the support member 130 in preventing hair or slender filaments from embedding into the cleaning portion 120.

[0081] Further, a distance between an end of the support member 130 away from the drum 110 and toward the cleaning portion 120 and an end of the cleaning portion 120 away from the drum 110 and toward the support member 130 is greater than or equal to the first height h.

[0082] Specifically, taking the end of the first support member 132 away from the drum 110 as a reference, the length of the gap between the cleaning portion 120 and the first support member 132 is a first length d, and the height of the first support member 132 protruding from the drum 110 is a first height h, which is less than the first length d.

[0083] like Figure 3 As shown, in some embodiments, optionally, along the cleaning rotation direction e of the roller brush 100, the second support member 134 is located on the rear side of the cleaning portion 120, that is, when the roller brush 100 is cleaning, the cleaning portion 120 first passes through the surface to be cleaned, and then the second support member 134 passes through the surface to be cleaned. Taking the end of the second support member 134 away from the drum 110 as a reference, the length of the gap between the cleaning portion 120 and the second support member 134 is a second length c; the height of the cleaning portion 120 protruding from the drum 110 is a second height b, and the second length c is greater than the second height b.
