Description

Technical Field

[0001] The utility model relates to a cleaning appliance, in particular to a rotary brush and a dust removal device. Background Art

[0002] In the prior art, the rotary brush used in the electric vacuum cleaner generally includes a cylindrical brush body, and a plurality of fixed grooves are provided on the outer peripheral side of the brush body. The fixed grooves extend spirally along the axial direction of the brush body, and the brush strips are installed and fixed in the fixed grooves. Generally, the brush strip installed in the same fixed groove is an integral part, and the material of the brush strip cannot be changed to meet different cleaning requirements. Brush strips of different materials can only be installed in different fixed grooves, for example, a bristle brush strip is installed in one fixed groove, and a rubber brush strip is installed in another fixed groove. Since the bristle brush strip and the rubber brush strip are at different positions on the outer peripheral side of the brush body, during the rotation of the rotary brush, generally only one brush strip will contact the surface to be cleaned, and brush strips of different materials will not contact the surface to be cleaned at the same time, and the cleaning function still has certain limitations. Utility Model Content

[0003] The utility model aims to provide a rotary brush, which solves the problem that only one type of brush strip can be installed in one fixed groove, resulting in limited cleaning function, and is conducive to increasing the wide application of the rotary brush.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rotary brush, including a brush body and a brush strip, a plurality of fixed grooves are provided on the outer peripheral side surface of the brush body, the fixed grooves extend spirally along the axial direction of the brush body, the brush strip includes a base installed in the fixed groove and a dust removal part extending out of the fixed groove, at least one brush strip in the fixed groove is divided into at least two short brush strips, the dust removal parts of two adjacent short brush strips in the same fixed groove are separated to form a groove, and the materials of the two adjacent short brush strips are the same or different.

[0005] After adopting the above technical scheme, the utility model has the following advantages: on the one hand, the short brush strips in the same fixed groove can be made of the same or different materials according to actual needs, which is conducive to increasing the wide applicability of the rotary brush; on the other hand, hair will inevitably be entangled on the rotary brush, and the grooves separated and formed between the dust removal parts of two adjacent short brush strips can accommodate the hair, and the hair will be concentrated in the grooves during the rotation of the rotary brush, which is convenient for cleaning after the dust removal device completes the cleaning work.

[0006] Furthermore, the width of the dust removal part gradually decreases from the base body to the direction away from the brush body, so that the groove forms a flared shape. The above technical solution can make the hair gather in the groove, which is convenient for subsequent cleaning.

[0007] Furthermore, the end surface of the dust removal part is an inclined surface or an outward convex arc surface. The above technical solution has a simple structure, is easy to shape, and has a guiding effect on the concentration of hair.

[0008] Furthermore, the bases of two adjacent short brush strips in the same fixed groove are in contact with each other; or, there is a gap between the bases of two adjacent short brush strips in the same fixed groove. With the above technical solution, the short brush strip will not move axially and will not easily generate noise; or, the gap is set to allow the short brush strip to have a certain amount of moving space in the axial direction of the brush body, so that the short brush strip can be moved axially when cleaning hair, so that the end face of the dust removal part is separated from the hair, making cleaning more efficient.

[0009] Furthermore, the cross section of the fixing groove is T-shaped or trapezoidal, and the cross section of the base body is adapted to the cross section of the fixing groove. The above technical solution provides a reliable fixing effect for the brush strip.

[0010] Furthermore, at least one end of the fixing groove is open and located at the end surface of the brush body, and the short brush strips are sequentially inserted into the fixing groove from the opening. With the above technical solution, it is more convenient to install the brush strips.

[0011] Furthermore, end caps are provided at both ends of the brush body, and the end faces of the brush strips near the end caps are perpendicular to the axial direction of the brush body. With the above technical solution, the end caps can prevent the short brush strips from escaping from the opening and the fixing groove, and can also facilitate the installation and fixing of the brush body into the dust removal device. The end faces of the brush strips near the end caps are perpendicular to the axial direction of the brush body, which can avoid the structure of the dust removal device and reduce the concentration of hair between the brush strips and the end caps.

[0012] The utility model also provides a dust removal device, comprising a machine body, wherein the machine body is equipped with the rotary brush described in any one of the above technical solutions.

[0013] Furthermore, the bottom surface of the body is provided with an air suction port, a supporting rib is provided at the air suction port, the rotary brush is located above the air suction port, the supporting rib is perpendicular to the axial direction of the rotary brush and is located below the groove on the brush bar. With the above technical solution, the hair will gradually concentrate in the groove after being entangled on the rotary brush. There is a certain space in the groove to accommodate the entangled hair after several cleanings, which can reduce the frequency of hair cleaning by users. At the same time, after the hair is concentrated in the groove, it is not easy to contact and generate friction with the structure of the air suction port, and the rotation resistance of the rotary brush is not easy to increase, ensuring that the dust removal device can be used normally for a long time.

[0014] Furthermore, the support ribs bulge upward and extend into the grooves. By adopting the above technical solution, the height of the space occupied by the support ribs is reduced, so that the brush bar is closer to the surface to be cleaned, which is conducive to improving the dust removal ability.

[0028] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0029] Embodiment 1:

[0030] refer to Figures 1 to 3 The utility model provides a rotary brush, including a brush body 100 and a brush strip 200. A plurality of fixed grooves 101 are provided on the outer peripheral side of the brush body 100. The fixed grooves 101 extend spirally along the axial direction of the brush body 100. The brush strip 200 includes a base 201 installed in the fixed groove 101 and a dust removal portion 202 extending out of the fixed groove 101. The brush strip 200 in at least one fixed groove 101 is divided into at least two short brush strips 200a. The dust removal portions 202 of two adjacent short brush strips 200a in the same fixed groove 101 are separated to form a groove 203. The materials of the two adjacent short brush strips 200a are the same or different. For example, in the present embodiment, four fixed grooves 101 are provided on the outer peripheral side of the brush body 100. The brush strip 200 in each fixed groove 101 is divided into five short brush strips 200a, and four grooves 203 are formed accordingly.

[0031] On the one hand, the short brush strips 200a in the same fixed groove 101 can be made of the same or different materials according to actual needs, which is conducive to increasing the wide applicability of the rotary brush. On the other hand, hair will inevitably be entangled on the rotary brush, and the grooves 203 separated and formed between the dust removal parts 202 of two adjacent short brush strips 200a can accommodate the hair. During the rotation of the rotary brush, the hair is concentrated in the grooves 203, which is convenient for cleaning after the dust removal device completes the cleaning work.

[0032] Combination Figure 2 and Figure 3 As can be seen, the width W of the dust removal part 202 gradually decreases from the base 201 to the direction away from the brush body 100, so that the groove 203 forms a flared shape, which can allow the hair to be collected in the groove 203, which is convenient for subsequent cleaning. Specifically, in this embodiment, the end surface 2021 of the dust removal part 202 is set as an inclined surface. Figure 4 As shown, the end surface 2021 of the dust removal portion 202 is set as an outward convex arc surface. It can be understood that other common shapes can also be used to make the groove 203 form a flared shape.

[0033] In order to facilitate the installation of the brush strip 200, the bases 201 of two adjacent short brush strips 200a in the same fixed groove 101 can be abutted, and no additional isolation parts are needed. The short brush strip 200a will not move axially and is not easy to generate noise. It is understandable that the bases 201 of two adjacent short brush strips 200a in the same fixed groove 101 may not be abutted, but have a certain gap 103, so that the short brush strip 200a has a certain moving space in the axial direction of the brush body 100. When cleaning hair, the short brush strip 200a can be moved axially to separate the end face of the dust removal part 202 from the hair, making cleaning more efficient.

[0034] In order to provide a reliable fixing effect for the brush strip 200, the cross section of the fixing groove 101 can generally be set to be T-shaped, such as Figure 5 As shown, the cross-sectional shape of the base 201 matches the cross-sectional shape of the fixing groove 101. It can be understood that in addition to the T-shape, other shapes can also be selected. Figure 6 Trapezoid as shown, or other common shapes.

[0035] In order to facilitate the installation of the brush strip 200, at least one end of the fixing groove 101 can be designed to have an opening 1011 located on the end surface of the brush body 100, and the short brush strip 200a can be inserted into the fixing groove 101 from the opening 1011. In addition, the installation can also be achieved by common methods such as deforming the brush strip 200 into the fixing groove 101 or fixing the brush strip 200 with fasteners.

[0036] In order to prevent the short brush strip 200a from escaping from the opening of the fixing groove 101, and also to facilitate the installation and fixation of the brush body 100 in the dust removal device, end covers 102 can be provided at both ends of the brush body 100. The end covers 102 can be installed by common means such as threads and snaps, which are easy to disassemble and assemble, and short brush strips 200a of different materials can be easily replaced. In order to avoid the structure of the dust removal device, the end face of the brush strip 200 close to the end cover 102 can be selected to be perpendicular to the axial direction of the brush body 100, and at the same time, the concentration of hair between the brush strip 200 and the end cover 102 can be reduced.

[0037] Embodiment 2:

[0038] The utility model also provides a dust removal device, such as Figure 7 As shown, the machine body 300 is provided with a rotary brush as described in any of the above embodiments. One or more rotary brushes can be provided as required, for example, two are provided in this embodiment and are distributed front and back. The dust removal device can be a vacuum cleaner, a mite removal device, etc.

[0039] The bottom surface of the body 300 is provided with an air suction port 301, and a supporting rib 302 is provided at the air suction port 301. The rotary brush is located above the air suction port 301, and the supporting rib 302 is perpendicular to the axial direction of the rotary brush and is located below the groove 203 on the brush strip 200. Figure 8 After the hair is entangled on the rotary brush, it will gradually gather in the groove 203. There is a certain space in the groove 203 to accommodate the entangled hair after several cleanings, which can reduce the frequency of hair cleaning by the user. At the same time, after the hair is concentrated in the groove 203, it is not easy to contact and generate friction with the structure of the air suction port 301, and the rotation resistance of the rotary brush is not easy to increase, ensuring that the dust removal device can be used normally for a long time.

[0040] Since the support rib 302 will occupy a certain space, combined with Fig. 9 and Fig.10 It can be seen that the support rib 302 can be designed to bulge upward and extend into the groove 203. When viewed along the axial direction of the rotary brush, there is a certain overlap between the support rib 302 and the brush bar 200. This can reduce the height of the space occupied by the support rib 302 and allow the brush bar 200 to be closer to the surface to be cleaned, which is beneficial to improving the dust removal ability. For example, in a mite removal device, the brush bar 200 is closer to the bedding, the beating effect will be enhanced, and the mite removal ability can be improved.

[0041] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
