Abstract
Description
A roller brush structure and a sweeper Technical Field
[0001] This utility model relates to the field of sweeping machine technology, and more specifically, to a roller brush structure and a sweeping machine. Background Technology
[0002] Robotic vacuum cleaners, such as those used in robotic vacuums, use high-speed motors to drive a rotating brush that lifts up dust and debris from the floor. A fan then sucks the dust and debris into the suction port, thus removing the dust and debris. The rotating brush is the main cleaning module of a robotic vacuum cleaner; it removes dust, hair, and other debris by sweeping the floor, and its performance directly affects the cleaning effect.
[0003] Some existing robot vacuums have bristles on their roller brushes. During cleaning, the bristles are prone to splitting and becoming tangled, resulting in poor cleaning power and difficulty in cleaning up dust and other small debris. In addition, when cleaning larger debris, the debris can easily get stuck on the bristles, preventing the bristles from cleaning up other debris smoothly, resulting in poor cleaning effect. Summary of the Invention
[0004] To address at least one of the aforementioned problems, this utility model provides a roller brush structure, comprising: a roller and a plurality of brush bodies disposed on the roller. A flexible sheet-like body is disposed on one side of each brush body. The length of each brush body protruding from the outer wall of the roller is a first length, and the length of the sheet-like body protruding from the outer wall of the roller is a second length, wherein the first length is greater than or equal to the second length. This roller brush structure is simple in structure and has low production cost. The sheet-like body on one side of the brush body provides support for the brush body during cleaning, preventing excessive bending, splitting, or misalignment. The support force of the sheet-like body also enhances the cleaning power of the brush body for small debris, resulting in a cleaner clean. The sheet-like body can also block larger debris, reducing the phenomenon of debris getting stuck on the brush body, resulting in better cleaning performance and more reliable use.
[0005] Optionally, the brush body is distributed on both sides of the sheet-like body.

[0007] Optionally, the brush body is distributed along a V-shaped trajectory, and the sheet-like body is V-shaped.
[0008] Optionally, the sheet-like body includes a first sheet and a second sheet connected together, and the connection between the first sheet and the second sheet forms an included angle, the included angle being 110°-160°.
[0009] Optionally, the brush body is made of nylon.
[0010] Optionally, one end of the brush body is connected to a mounting block, and one end of the sheet-like body is connected to the mounting block.
[0011] Optionally, the roller is provided with a mounting cavity for mounting the mounting block, and the roller is provided with a slot communicating with the mounting cavity, through which the brush body and the sheet-like body pass.
[0012] Optionally, the mounting cavity is provided with a side opening, and the mounting block is inserted into the mounting cavity from the side opening along the axial direction of the roller. One end of the roller is provided with an end cap. When the mounting block is inserted into the mounting cavity, the end cap is installed on one side of the side opening to limit the mounting block.
[0013] Compared to existing technologies, the roller brush structure of this utility model is simple in structure and has low production cost. A sheet-like body is provided on one side of the brush body, which supports the brush body during cleaning, preventing excessive bending, splitting, or misalignment. The supporting force of the sheet-like body also enhances the brush's cleaning power for fine debris, resulting in a cleaner finish.

Detailed Implementation
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.
[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0028] Referring to Figures 1-9, this embodiment of the utility model provides a roller brush structure suitable for installation on a sweeper. The roller brush structure includes: a roller 1 and multiple brush bodies 2 disposed on the roller 1. A flexible sheet 3 is disposed on one side of each brush body 2. The length of the brush body 2 protruding from the outer wall of the roller 1 is a first length L, and the length of the sheet 3 protruding from the outer wall of the roller 1 is a second length M. The first length L is greater than or equal to the second length M, so that the end of the brush body 2 away from the roller 1 can contact the ground, thereby ensuring the cleaning effect of the brush body 2 on the ground debris. The structure design is reasonable. If the first length L is less than the second length M, it will lead to... The problem of brush body 2 failing to make smooth contact with the ground, affecting the cleaning effect; this roller brush has a simple structure and low production cost; a plate-like body is set on one side of the brush body, which can support the brush body when sweeping up garbage, simulating a broom, so that the brush body is not prone to excessive bending, splitting, or tangling during sweeping. The supporting force of the plate-like body can also improve the sweeping power of the brush body for small garbage, resulting in a cleaner sweep; the plate-like body can also block larger garbage to a certain extent, so that the plate-like body can sweep up larger garbage, reducing the phenomenon of garbage getting stuck on the brush body, resulting in better sweeping effect and more reliable use.
[0029] Referring to Figures 1 and 2, brushes 2 are distributed on both sides of the sheet-like body 3. Increasing the number of brushes 2 allows the brushes 2 on one side of the sheet-like body 3 to first contact the garbage for the first cleaning during sweeping, and then the brushes 2 on the other side of the sheet-like body 3 perform a second cleaning, improving the cleaning effect and making the cleaning more thorough. The sheet-like body 3 is made of non-woven fabric, which has a simple manufacturing process and low production cost. Non-woven fabric has a certain degree of water absorption, which can reduce the residual moisture on the ground after sweeping when cleaning some wet garbage. Non-woven fabric can be softly deformed, making the garbage sweeping work more gentle and stable. During sweeping, the non-woven fabric provides a reaction support force to the brushes, allowing the brushes to mimic the sweeping action of a broom and better clean dust and garbage.
[0030] Referring to Figures 1, 2, 8, and 9, the brush body 2 is distributed along a V-shaped trajectory, and the sheet-like body 3 is V-shaped to collect garbage during sweeping and sweep it into the dustbin inlet of the sweeper. The rotation direction of the roller 1 is as indicated by the arrow in Figure 1, and the shape of the sheet-like body 3 matches the V-shaped trajectory of the brush body 2. The sheet-like body 3 includes a first sheet 31 and a second sheet 32 connected together. The first sheet 31 and the second sheet 32 are symmetrically or approximately symmetrically arranged. An included angle A is formed at the connection between the first sheet 31 and the second sheet 32. The included angle A is 110°-160°. In this embodiment, the included angle A is 140°. The included angle A is set appropriately. The included angle A should not be set too large to avoid poor garbage collection effect. The included angle A should not be set too small to avoid some garbage getting stuck at the included angle A.
[0031] Referring to Figures 1, 3, and 4, the brush body 2 is made of nylon. Nylon brush bodies have good hardness and toughness, resulting in good cleaning ability. Furthermore, nylon brush bodies have high wear resistance, allowing them to maintain their original shape and performance for a long time without easily deforming, breaking, or shedding bristles. One end of the brush body 2 is connected to the mounting block 4, and the end of the brush body 2 is fixed to the mounting block 4 by means of integral molding, glue, welding, etc. One end of the sheet-like body 3 is connected to the mounting block 4, and the end of the sheet-like body 3 is fixed to the mounting block 4 by means of glue, welding, sewing, etc.
[0032] Referring to Figures 1, 3, 4, and 5, the roller 1 is provided with a mounting cavity 101 for mounting the mounting block 4. The roller 1 is provided with a slot 102 communicating with the mounting cavity 101. The brush body 2 and the sheet-like body 3 penetrate the slot 102, allowing the brush body 2 to extend outwards from the slot 102 and thus contact the debris on the ground. The mounting block 4 is simple to install, stable after installation, and has a reasonable structural design. The mounting cavity 101 is provided with a side opening 103, and the mounting block 4 extends from the side opening 103 along the roller 1... The roller 1 is installed into the mounting cavity 101 in the axial direction. One end of the roller 1 is provided with an end cap 5, which is adapted to connect with the body of the sweeper. The connection structure between the end cap and the body of the sweeper is existing technology and will not be described in detail here. When the mounting block 4 is installed into the mounting cavity 101, the end cap 5 is installed on one side of the side opening 103 by bolts. The end cap 5 limits the mounting block 4 to prevent the mounting block 4 from accidentally falling out of the mounting cavity 101. The mounting block 4 is installed firmly and is not prone to large displacement, which improves the stability during sweeping.
[0033] The roller brush structure of this utility model is simple in structure and low in production cost. A plate-like body is provided on one side of the brush body, which can support the brush body when cleaning up garbage. This prevents the brush body from bending excessively and from splitting or becoming disordered. The support force of the plate-like body can also improve the cleaning power of the brush body for small garbage, resulting in a cleaner cleaning. The plate-like body can also block larger garbage to a certain extent, reducing the phenomenon of garbage getting stuck on the brush body, resulting in better cleaning effect and more reliable use.
[0034] In addition, this utility model also provides a sweeper that includes the above-mentioned roller brush structure. This sweeper also has the same beneficial effects as the above-mentioned roller brush structure, which will not be described in detail here.
