Description

Technical Field

[0001] The utility model belongs to the field of precision measurement, and in particular relates to a garbage escape prevention cover used on a roller brush. Background Art

[0002] Cleaning brushes are widely used in a variety of cleaning equipment, such as floor sweepers, car washers, and industrial cleaning systems. These devices effectively remove trash, dirt, and debris from floors and surfaces using rotating brushes. However, with the increasing demand for cleaning, existing cleaning brush technology has exposed some shortcomings when it comes to waste collection.

[0003] Traditional cleaning roller brushes typically consist of the following main components: a roller brush frame, a roller brush body, and a brush handle. The roller brush body typically has bristles and is mounted on the roller brush frame, while the brush handle is fixed to the roller brush frame. For example, patent publication number CN220917361U, titled "Roller Brush Mechanism and Cleaning Device," features an exposed roller brush.

[0004] While these structures are effective at cleaning surfaces to a certain extent, they have several drawbacks in the waste collection process:

[0005] 1. Waste Escape: Existing cleaning roller brushes often fail to fully capture waste during cleaning. As the roller brush rotates, debris and dirt are easily thrown onto the outside of the brush or into the gaps between the bristles, preventing some debris from being effectively captured and removed. This not only affects cleaning effectiveness but can also cause secondary contamination.

[0006] 2. Bristle wear: After long-term use, the wear of the bristles will also affect the cleaning effect of the roller brush. When the wear is severe, the bristles cannot effectively contact the ground or surface, resulting in reduced cleaning efficiency and the roller brush cannot adapt to different cleaning needs.

[0007] 3. Limited cleaning range: Due to the limitations of bristle design and roller brush structure, the cleaning range is usually limited. Some designs cannot effectively cover smaller gaps or corners, and these areas may leave uncleaned garbage.

[0008] 4. Difficulty in Maintenance and Cleaning: Existing cleaning brush designs also present certain difficulties in cleaning and maintaining after waste collection. This is especially true when dealing with sticky waste or liquids, as cleaning the residue from the brush may require additional time and labor.

[0009] 5. Low efficiency: Due to the problems of garbage escape and bristle wear, the overall cleaning efficiency of the existing roller brush cleaning equipment will be affected when processing large amounts of garbage or under high-frequency use.

[0010] There are also cleaning roller brushes with a cover. For example, in the Chinese utility model patent with the announcement number CN220675902U and the patent name "Cleaning Equipment", a floor brush structure shell covering the roller brush is disclosed, and its air duct structure is behind it. Its disadvantage is that the cover is not removable, which is very inconvenient for replacing the roller brush and cleaning the equipment itself. It is more suitable for cleaning dust. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to provide a garbage escape prevention cover for a roller brush which can effectively prevent garbage from escaping and can be disassembled to improve cleaning efficiency in response to the status quo of the above-mentioned prior art.

[0012] The present invention solves the above-mentioned technical problems by adopting a technical solution: a garbage escape prevention cover for a roller brush, comprising a cover body, a cover cavity within the cover body for covering the roller brush body, and a sewage suction pipe extending from the cover cavity to the outside world; and a detachable restraining mechanism between the cover body and the roller brush frame for confining the roller brush body within the cover cavity. The roller brush of the present invention can be removed for use alone or attached to the cover body.

[0013] In a preferred solution, the roller brush holder is also located in the cover cavity.

[0014] In the preferred embodiment, the opening of the sewage suction pipe in the housing cavity is located above the roller brush body in the forward direction. This is different from the structure of the patent application CN220675902U in the background art, which is titled "Cleaning Equipment." In that patent, the sewage suction pipe is located behind the roller brush body, while in the present invention, it is located above the roller brush body in the forward direction. This arrangement not only allows garbage moving toward the rear of the roller brush body to tumble forward into the sewage suction pipe, but also allows the roller brush body to suck away floating garbage in front of it before it, reducing the cleaning burden of the roller brush body. Especially when cleaning in water, since the density of water is greater than that of air, garbage in the housing cavity is more easily sucked away by the sewage suction pipe in front of the roller brush body.

[0015] In this solution, the detachable restraining mechanism includes a first step on one side of the cover and a first support bar on the other side. The first step and the first support bar are respectively located below the roller brush holder. A first rotating shaft is connected between one end of the first support bar and the cover, and a first locking structure is provided between the other end and the cover. The roller brush holder is restrained within the cover cavity by the first step and the first support bar. The roller brush holder can be removed by unlocking the first support bar.

[0016] In the above preferred embodiment, the first locking structure includes a first pin on the cover body and a first groove on the first support bar for the first pin to engage in. When the first pin is disengaged from the first groove, the first support bar loses its restraint and is released to rotate about the first rotation axis.

[0017] In another embodiment, the detachable restraining mechanism includes a first support bar located on one side of the cover body and a second support bar located on the other side of the cover body. The first support bar and the second support bar are respectively located below the roller brush frame. A first rotating shaft is connected between one end of the first support bar and the cover body, and a first locking structure is provided between the other end and the cover body. A second rotating shaft is connected between one end of the second support bar and the cover body, and a second locking structure is provided between the other end and the cover body. The roller brush frame is restrained within the cover cavity by the first and second support bars. When the first and second support bars are unlocked, the first support bar is no longer restrained and is allowed to rotate around the first rotating shaft, allowing the roller brush frame to be removed.

[0018] In the above preferred embodiment, the first locking structure includes a first pin located on the cover body and a first groove located on the first support bar for the first pin to be engaged with; the second locking structure includes a second pin located on the cover body and a second groove located on the second support bar for the second pin to be engaged with.

[0019] In the preferred embodiment, the first and second rotating shafts are located behind the roller brush body. Thus, when installing the cover, the roller brush body does not need to be installed from the rear of the cover, but from the front of the cover, so that the clean rear of the cover will not be scratched and contaminated by garbage during installation.

[0020] Another solution for temporarily restraining the roller brush rack is: the detachable restraining mechanism includes a third pin located on the cover body and extending and retracting parallel to the axis of the roller brush body, and a third groove located on the roller brush rack for the third pin to be inserted into. There are two third grooves respectively arranged on both sides of the roller brush rack, and there are also two third pins respectively arranged on both sides of the cover body.

[0021] In a preferred solution, the cover body is provided with two or more rollers, which can avoid the roller brush body from serving as a load-bearing part and extend the life of the bristles; the cover body is provided with a notch for the brush rod of the roller brush frame to be inserted into.

[0022] To sum up, compared with the existing technology, the utility model of the anti-garbage escape cover used on the roller brush has a detachable cover structure, which can be used in conjunction with the roller brush and can also be disassembled and used alone. Since the cover is detachable, it is convenient to replace and clean the roller brush. In the preferred solution, the sewage suction pipe is creatively arranged in the forward direction of the roller brush body, which has a good sewage suction effect in water and effectively reduces the cleaning burden of the roller brush body.
