Description

Technical Field

[0001] This utility model relates to the field of roller brush technology, and in particular to a rubber strip roller brush. Background Technology

[0002] Vacuum cleaners, washing machines and other cleaning appliances are equipped with floor brushes and roller brushes to suck up dust, stains and particles, catch hair and remove mites.

[0003] As a core component of cleaning appliances, the cleaning roller brush assembly currently used in commercially available cleaning appliances can be divided into two types: one is a rigid filament strip brush roller brush that uses rigid filaments to achieve a 360° spiral interweaving; the other is a silicone strip roller brush with segmented interweaving. Both rigid filament strip brush roller brushes and silicone strip brushes can achieve good dust removal effects on floors and carpets.

[0004] While the aforementioned hard-filament brush rollers achieve 360° interlacing due to the spread-out tips of the hard filaments, they are prone to tangling with residual hair when cleaning. This hair can get into the roller brush bearings of the cleaning appliance, not only reducing the cleaning effect but also potentially affecting the normal rotation of the drive shaft and bearings. Furthermore, it increases the difficulty of cleaning the appliance, requiring manual cleaning by the consumer. In contrast, the aforementioned rubber-strip brushes offer better protection against hair tangling, but the blades are a single unit, preventing 360° rotation and interlacing, or causing them to fold over and become ineffective. They can only be segmented to ensure the blades remain upright, resulting in a complex mold structure and high manufacturing difficulty for the roller brush tube.

[0005] Therefore, there is an urgent need in this field for a new type of rubber strip roller brush to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rubber strip roller brush to solve the problems existing in the prior art. The rubber strip of the roller brush is inserted into the roller brush tube in a spiral distribution pattern at 360°, which can prevent hair from getting tangled.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] This utility model discloses a rubber strip roller brush, including a roller brush tube body, a plurality of roller brush rubber strips are installed on the side wall of the roller brush tube body, the roller brush rubber strips are spirally distributed on the side wall of the roller brush tube body, and a fabric strip is installed on one side of the roller brush rubber strip.

[0009] Preferably, the roller brush has two rubber strips.

[0010] Preferably, the material of the roller brush strip is silicone.

[0011] Preferably, the material of the woven strip is nylon or polyester.

[0012] Preferably, the side wall of the roller brush tube is provided with a guide mounting groove, and the roller brush rubber strip is inserted into the guide mounting groove.

[0013] Preferably, the material of the roller brush tube is ABS plastic.

[0014] Preferably, the roller brush strip is wrapped around the outer wall of the roller brush tube one or two times.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] This invention uses roller brush strips to clean the floor, thus preventing hair entanglement. The roller brush strips are spirally mounted on the roller brush tube, allowing for 360° insertion. Furthermore, this invention requires only two roller brush strips, reducing the number of strips needed compared to existing strip-based roller brushes, thereby lowering manufacturing costs and simplifying the structure.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The purpose of this invention is to provide a rubber strip roller brush to solve the problems existing in the prior art. The rubber strip of the roller brush can be inserted into the roller brush tube in a spiral distribution manner at 360°, and can prevent hair from getting tangled.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figures 1-5As shown, this embodiment provides a rubber strip roller brush, including a roller brush tube 1, which is a tubular structure, no different from the tubular structure of existing roller brushes. Several roller brush rubber strips 2 are installed on the side wall of the roller brush tube 1, and each roller brush rubber strip 2 is spirally distributed on the side wall of the roller brush tube 1, ensuring that the individual roller brush rubber strips 2 do not interfere with each other. A fabric strip 3 is installed on one side of each roller brush rubber strip 2 to improve its wear resistance and provide some protection.

[0038] In actual use, the roller brush tube 1 is installed on the corresponding cleaning equipment (such as a vacuum cleaner or floor scrubber). During cleaning, as the roller brush tube 1 rotates, the side with the fabric strip 3 will contact the ground first. The abrasion resistance of the fabric strip 3 ensures that the roller brush rubber strip 2 is not damaged. The toughness of the roller brush rubber strip 2 allows it to effectively pat and scrape the floor and carpet, thereby cleaning dust and debris and preventing hair from getting tangled.

[0039] In this embodiment, two roller brush strips 2 are generally sufficient. Of course, those skilled in the art can adjust the specific number of roller brush strips 2 according to the length of the roller brush tube 1 and the roller brush strips 2, and can set one, three or more.

[0040] In this embodiment, the roller brush strip 2 is made of silicone, which has a certain degree of flexibility, enabling it to pat and scrape dust off the ground. Of course, those skilled in the art can replace it with other alternative materials, and it is not limited to this one.

[0041] In this embodiment, the fabric strip 3 is made of nylon or polyester, which is inexpensive and has a certain degree of abrasion resistance, thereby effectively protecting the roller brush strip 2 and preventing it from directly contacting the ground.

[0042] In this embodiment, as Figures 2-3 As shown, the side wall of the roller brush tube 1 is provided with an approximately rectangular guide mounting groove, and the cross-section of the roller brush strip 2 is T-shaped. One side of the roller brush strip 2 can be inserted into the guide mounting groove, thereby achieving the fixing effect of the roller brush tube 1 and the roller brush strip 2.

[0043] In this embodiment, the material of the roller brush tube 1 is ABS plastic, which is a common material for the roller brush tube 1. If the customer has a need, those skilled in the art can also use other materials to make the roller brush tube 1.

[0044] In this embodiment, the roller brush strip 2 is wound around the outer wall of the roller brush tube 1 once (i.e., 360°) or twice (720°). Of course, those skilled in the art can further adjust the number of winding turns of the roller brush strip 2 according to actual needs, such as three or more turns. In addition, those skilled in the art can also set each roller brush strip 2 to be wound around the outer wall of the roller brush tube 1 by 1 / 4 turn or 1 / 2 turn, etc. Of course, the number of roller brush strips 2 also needs to be adjusted accordingly to meet the 360° interlacing requirement.
