Description

Technical Field

[0001] This utility model belongs to the field of magnetic brush technology, and specifically relates to a magnetic brush structure. Background Technology

[0002] When cleaning fish tanks and window glass, magnetic brushes are required. These brushes consist of an inner brush and an outer brush, both of which are embedded with magnets. A brush cloth is also placed on the surface of the inner and outer brushes. Existing magnetic brushes have a plastic barrier with a thickness of 1-2mm to fix the magnets. Although this can position the magnets, it reduces the magnetic force of the magnets, thereby reducing the wiping force and affecting the stability and effectiveness of the magnetic brush, thus limiting its applicability. Summary of the Invention

[0003] The purpose of this invention is to provide a magnetic brush structure with a reasonable structural design that is conducive to improving wiping force.

[0004] The technical solution to achieve the purpose of this utility model is a magnetic brush structure, including an inner brush body and an outer brush body. The brush surfaces of the inner brush body and the outer brush body are provided with at least two magnet mounting holes, and the outer end of the inner wall of the magnet mounting hole is integrally formed with a limiting protrusion ring.

[0005] A magnet block is fixed inside the magnet mounting hole, and a limiting ring groove that mates with the limiting protrusion is provided on the outer edge of the magnet block.

[0006] The magnet block is inserted into the magnet mounting hole and fixed by being inserted into the limiting ring groove by the limiting protrusion ring, and the surface of the magnet block is flush with the brush surface of the inner brush body or the outer brush body.

[0007] A brush cloth is fixed on the brush surface of the inner brush body and the outer brush body, and the surface of the brush cloth is attached to the outer surface of the magnet block.

[0008] A further preferred embodiment is that a scraper is fixed to the end of the outer brush body;

[0009] The edge of the scraper blade is flush with the brush cloth of the outer brush body.

[0010] A further preferred embodiment is that the number of magnet mounting holes is two or three.

[0011] A further preferred embodiment is that a handle is fixed to the inner brush body.

[0012] A further preferred embodiment is that both the inner brush body and the outer brush body include a support and a cover, and the magnet mounting hole and the brush bristles are located on the side of the support away from the cover.

[0013] A further preferred embodiment is that the brush cloth is a plastic brush cloth or a fiber brush cloth.

[0014] This invention has several advantages: Its structure is rationally designed, with magnet mounting holes on both the inner and outer brush bodies. A limiting protrusion is integrally formed on the outer end of the inner wall of each magnet mounting hole, allowing the magnet to be positioned after installation. Furthermore, the outer surface of the magnet is flush with the surfaces of the inner and outer brush bodies, preventing the magnet from loosening or falling off. This reduces the need for a plastic shielding layer, increases the magnet's magnetic attraction, and, combined with the brush cloth, enhances wiping force and cleaning effectiveness. It is stable, reliable, and highly adaptable. Attached Figure Description

[0021] 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.

[0022] Example

[0023] See Figures 1 to 4As shown, a magnetic brush structure includes an inner brush body 1 and an outer brush body 2. The brush surfaces of both the inner and outer brush bodies are provided with at least two magnet mounting holes 3, the number of which is two or three. A limiting protrusion ring 4 is integrally formed on the outer end of the inner wall of each magnet mounting hole. In this embodiment, both the inner and outer brush bodies are conventional structures of the prior art, simply applied. Both the inner and outer brush bodies include a support and a cover. The magnet mounting holes and brush bristles are located on the side of the support away from the cover. The support and cover can be fixed by screws or other snap-fit ​​methods.

[0024] In this embodiment, a magnet block 5 is fixed inside the magnet mounting hole, and a limiting ring groove 6 that mates with the limiting protrusion ring is provided on the outer edge of the magnet block. In actual application, the shape of the limiting ring groove matches that of the limiting protrusion ring, mainly for limiting the magnet block. During assembly, the magnet block is inserted into the magnet mounting hole and fixed by the limiting protrusion ring being inserted into the limiting ring groove, and the surface of the magnet block is flush with the brush surface of the inner or outer brush body. A brush cloth 7 is fixed on the brush surface of the inner and outer brush bodies, and the surface of the brush cloth is attached to the outer surface of the magnet block. The brush cloth is a plastic brush cloth or a fiber brush cloth. Through the above structure, the brush cloth is in direct contact with the magnet block, reducing the plastic shielding layer, thereby ensuring the magnetic attraction between the inner and outer brush bodies, which is beneficial to improving the wiping force and has strong applicability.

[0025] In this embodiment, a scraper 8 is fixed to the end of the outer brush body; the edge of the scraper is flush with the brush cloth of the outer brush body. This allows for scraping during wiping, improving cleaning effectiveness and cleanliness.

[0026] A handle 9 is fixed to the inner brush body. This is for ease of use and is a common structure in existing technology, therefore it is not described in detail.

[0027] This invention has several advantages: Its structure is rationally designed, with magnet mounting holes on both the inner and outer brush bodies. A limiting protrusion is integrally formed on the outer end of the inner wall of each magnet mounting hole, allowing the magnet to be positioned after installation. Furthermore, the outer surface of the magnet is flush with the surfaces of the inner and outer brush bodies, preventing the magnet from loosening or falling off. This reduces the need for a plastic shielding layer, increases the magnet's magnetic attraction, and, combined with the brush cloth, enhances wiping force and cleaning effectiveness. It is stable, reliable, and highly adaptable.

[0028] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
