Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sweeping and cleaning, and more specifically to a roller brush for being installed on ground cleaning equipment. Background Art
[0002] Floor cleaning equipment is used to remove dust and other debris from surfaces such as carpets and hard floors. Floor cleaning equipment typically first applies a cleaning fluid or solution to the floor, then agitates the surface with a brush. Suction is then used to recover the applied cleaning fluid, removing dust or debris along with the recovered fluid from the surface. Conventional floor cleaning equipment includes a main unit and a floor brush assembly, which is located at the bottom end of the main unit.
[0003] The floor brush assembly includes a bottom shell and a shell cover. The bottom shell is provided with an air intake channel, the shell cover is provided with a suction channel, the bottom of the shell cover is provided with a suction port, and the shell cover is detachably connected to the bottom shell. The bottom of the bottom shell is provided with a roller brush assembly, which generally includes two roller brushes, and the roller brushes are detachably connected to the bottom shell. The roller brush includes a rotating shaft, and bristles are fixedly connected to the side walls of the rotating shaft. The rotating shaft in the prior art is generally circular, and the bristles are vertically connected to the side walls of the rotating shaft. During the rolling process of the roller brush, the bristles are in vertical contact with the ground. Since the bristles have a certain hardness, the roller brush contacts the ground or the surface of the object to be cleaned with greater force during the rolling process, and long-term use will scratch the ground or the surface of the object to be cleaned. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a roller brush, the bristles of which will not vertically contact the ground or the surface of the object to be cleaned during the rolling process, and will not scratch the ground or the surface of the object to be cleaned during use.
[0005] The technical solution of the present utility model is to provide a roller brush with the following structure, including a roller brush, a rotating shaft and bristles, the rotating shaft including a shaft body, a plurality of convex strips are provided on the shaft body, the convex strips are arranged along the length direction of the shaft body, the convex strips are bent around the shaft body, a side wall of the convex strips adjacent to the shaft body is a bearing surface, the bearing surface is a curved surface, the bristles are arranged in sequence along the length direction of the bearing surface and are fixedly connected; the height of the bristles is greater than the height of the convex strips and the bristles are not perpendicular to the shaft body; a channel for dust or garbage to pass through is formed between the bristles of two adjacent convex strips.
[0006] After adopting the above structure, the roller brush of the utility model has the following advantages compared with the prior art:
[0007] Because the roller brush of the present invention has a ridge on its shaft, the ridge is bent around the shaft, and a side wall adjacent to the ridge and the shaft serves as a bearing surface, the bearing surface is a curved surface, and the bristles are arranged in sequence along the length of the bearing surface and are fixedly connected; the height of the bristles is greater than the height of the ridge, and the bristles are not perpendicular to the shaft; a channel for dust or garbage to pass through is formed between the bristles of two adjacent ridges. With this structure, the bristles of the roller brush will not make vertical contact with the ground or the surface of the object being cleaned during rolling, and will not scratch the ground or the surface of the object being cleaned during use. During rolling, the dust or garbage brushed off will enter the channel, making cleaning easier.
[0008] As an improvement, the ridges are bent in a "V" shape around the shaft, with the ends of the ridges connected to the ends of the shaft, and the middle of the ridges connected to the middle of the shaft. With this structure, as the roller brush rolls, dust or trash picked up by it will enter the channel. Due to the dust or trash at both ends of the channel or the "V"-shaped structure of the channel, the dust or trash at both ends will be concentrated in the middle of the channel, making it easier to clean later.
[0009] As an improvement, the convex strips are symmetrically arranged with the perpendicular midline of the shaft as the symmetry line. After adopting this structure, the symmetrical structure can make the roller brush roll more stably and better collect dust and garbage.
[0010] As an improvement, the ridges are vertically arranged on the shaft, with the roots of two adjacent ridges connected to each other; the sidewalls of the ridges away from the bearing surface are close to the bearing surface of the adjacent ridges. With this structure, the structural design is more reasonable.
[0011] As an improvement, the angle between the bristles and the shaft gradually increases from the middle of the convex strip to the end of the convex strip, and the bristles in the middle of the convex strip are parallel to the shaft. With this structure, the brushing effect is better and the floor and the surface being cleaned will not be scratched.
[0012] As an improvement, the bristles gradually approach the sidewalls of adjacent ridges from the middle of the ridges to the ends of the ridges, so that the bristles in the middle of the ridges do not contact the sidewalls of adjacent ridges, while the bristles at the ends of the ridges touch the sidewalls of adjacent ridges. This structure is more reliable.
[0013] As an improvement, there are four convex strips. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that these detailed descriptions are merely descriptions of exemplary embodiments of the present application and are not intended to limit the scope of the present application in any way. Throughout the specification, the same reference numerals refer to the same elements.
[0019] In the drawings, the thickness, size and shape of objects have been slightly exaggerated for ease of explanation. The drawings are only examples and are not drawn strictly to scale.
[0020] It should also be understood that the terms “comprises,” “has,” “includes,” and “comprising,” when used in this specification, indicate the presence of the stated features, integers, steps, operations, elements, and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts, and / or combinations thereof.
[0021] like Figures 1 to 3 As shown, this embodiment discloses a roller brush comprising a rotating shaft and bristles 2. The rotating shaft comprises a cylindrical shaft 1 with connecting portions at both ends for connecting to a floor cleaning device. The shaft 1 is provided with a plurality of ridges 3, which are arranged along the length of the shaft 1. There are four ridges 3.
[0022] The ridges 3 are bent around the shaft 1 in a V-shape, with the ends of the ridges 3 connected to the ends of the shaft 1 and the middle of the ridges 3 connected to the middle of the shaft 1. The ridges 3 are symmetrically arranged with the perpendicular midline of the shaft 1 as the line of symmetry.
[0023] The ridges 3 are vertically arranged on the shaft 1, with the bases of two adjacent ridges 3 connected. A sidewall of the ridge 3 adjacent to the shaft 1 serves as a bearing surface 301, which is a curved surface. The sidewall of the ridge 3 away from the bearing surface 301 is closer to the bearing surface 301 of the adjacent ridge 3.
[0024] The bristles 2 are arranged in sequence along the length of the bearing surface 301 and are fixedly connected. The angle formed between the bristles 2 and the shaft 1 gradually increases from the middle of the ridge 3 to the end of the ridge 3. The bristles 2 in the middle of the ridge 3 are parallel to the shaft 1. The bristles 2 gradually approach the sidewalls of the adjacent ridge 3 from the middle of the ridge 3 to the end of the ridge 3. The bristles 2 in the middle of the ridge 3 do not contact the sidewalls of the adjacent ridge 3, and the bristles 2 at the end of the ridge 3 touch the sidewalls of the adjacent ridge 3.
[0025] The height of the bristles 2 is greater than that of the ridges 3 and the bristles 2 are not perpendicular to the shaft 1 ; a channel 4 for dust or garbage to pass through is formed between the bristles 2 of two adjacent ridges 3 .
[0026] The roller brush disclosed in this specific embodiment does not have the bristles 2 in vertical contact with the ground or the surface of the object being cleaned during the rolling process. The bristles 2 are in oblique contact with the ground or the surface of the object being cleaned. Therefore, the force exerted by the bristles 2 on the ground or the surface of the object being cleaned is relatively small, but it does not affect the removal of dust or garbage on the ground or the surface of the object being cleaned, so that users can use it with confidence.
[0027] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the principles and spirit of the present application are included in the scope of protection of the present application.
