Description

Background of the invention

[0001] The present invention relates to a cleaning device and in particular to a cleaning device for cleaning the surfaces of tools or parts.

[0002] When used over a long period of time, parts of tools or equipment can develop problems such as surface rust, rust stains, or accumulated dirt. Most tools or parts can be reused after their surfaces have been cleaned, thus avoiding the need for replacement. However, conventional cleaning methods involve manually scraping off rust and dirt using tools such as screwdrivers or knives, or sanding the surface with abrasive cloth. These methods are not only inefficient but often lead to poor cleaning results and can easily scratch the surface.

[0003] Therefore, there is a need for a cleaning device that reduces and / or avoids the disadvantages mentioned above. Brief description of the invention

[0004] In general, the present disclosure describes a cleaning device comprising a connecting member, a brush assembly, and a restricting member. The connecting member has a drive end, a driven end suitable for connection to a power tool, and a drive hole extending from the drive end to the driven end. At least one first restricting slot is formed on an inner surface of the drive hole. The brush assembly includes a retaining member removably connected to the drive hole, and a brush member mounted on the retaining member. A second restricting slot corresponding to the at least one first restricting slot is formed on an outer surface of the retaining member. The brush member has a rough surface. The restricting member removably engages the at least one first restricting slot and the second restricting slot.

[0005] The present invention will become more apparent from the following detailed description of illustrative embodiments of the present invention, which are described in conjunction with the drawings. Short description of the drawings Fig. 1 shows a perspective view of a cleaning device according to an embodiment of the present invention; Fig. Figure 2 shows an exploded perspective view of the cleaning device of Fig. 1; and Fig. 3 shows a cross-sectional view of the cleaning device of Fig. 1. Detailed description of the invention

[0006] The Fig. 1 to 3 show a cleaning device according to an embodiment of the present invention. The cleaning device comprises a connecting element 10, a brush assembly 20, and a limiting element 30.

[0007] The connecting element 10 has a drive end 11, a driven end 12 suitable for connection to a power tool, and a drive hole 13 extending from the drive end 11 to the driven end 12. At least one first limiting slot 131 is formed on an inner surface of the drive hole 13. In the present embodiment, the drive hole 13 may be a polygonal hole. A plurality of drive surfaces 132 are further provided on the inner surface of the drive hole 13. The number of the at least one first limiting slot 131 is a plurality in this embodiment, and the plurality of first limiting slots 131 are each formed on the plurality of drive surfaces 132. In addition, each pair of adjacent drive surfaces 132 has a rounded corner 133.The connecting element 10 further includes a driven hole 14 located at the driven end 12 and communicating with the drive hole 13. The driven hole 14 is adapted to be releasably connected to the power tool so that the connecting element 10 can be rotatably driven by the power tool. Furthermore, the driven hole 14 may be a square hole, and the connecting element 10 further includes an annular groove 15 located on an outer surface of the driven end 12. The annular groove 15 may be engaged with a retaining ring to ensure that the connecting element 10 does not accidentally fall off the power tool during use.

[0008] The brush assembly 20 includes a holding member 21 detachably connected to the drive hole 13 and a brush member 22 mounted on the holding member 21. A second limiting slot 214 corresponding to the first limiting slots 131 is formed on an outer surface of the holding member 21. The brush member 22 has a rough surface 221. Furthermore, the holding member 21 includes a head 211 and a body 212 connected to the head 211. The brush member 22 is mounted on the head 211. The second limiting slot 214 is formed on an outer surface of the body 212. In the embodiment, the body 212 may have a polygonal cross-section corresponding to the drive hole 13 so that the body 212 can be detachably inserted into the drive hole 13. Furthermore, the holding member 21 further includes a receiving recess 213 disposed in the head 211.The brush element 22 has a circular cross-section and includes a large-diameter portion 222, a small-diameter portion 223 connected to the large-diameter portion 222, and a through-hole 224 penetrating the opposite sides of the brush element 22. In the embodiment, the rough surface 221 may be formed on at least one end surface and a peripheral surface of the large-diameter portion 222. The small-diameter portion 223 is received in and connected to the receiving recess 213 so that the brush element 22 can be mounted on the head 211. The through-hole 224 is suitable for receiving tools or parts to be cleaned, such as screws or nuts, to clean their peripheries through an inner surface of the through-hole 224.

[0009] The limiting member 30 removably engages the first limiting slots 131 and the second limiting slot 214, allowing the brush assembly 20 to be selectively connected to or disconnected from the connecting member 10, thereby facilitating the replacement of various brush assemblies 20. In the embodiment, the limiting member 30 may be annular and has an opening 31 that is expandable or contractible, meaning that the limiting member 30 may be a C-shaped retaining ring that can be manipulated by tools such as retaining ring pliers to selectively release it from the second limiting slot 214, thereby allowing the body 212 of the retaining member 21 to be released from the drive hole 13 of the connecting member 10 for replacement of the brush assembly 20.

[0010] In summary, in this embodiment, the driven end 12 of the connecting member 10 is adapted to be connected to the power tool, thereby enabling the connecting member 10 to be driven by the power tool to rotate synchronously with the brush assembly 20 to clean the surface of tools or parts. Furthermore, the limiting member 30 can be selectively released from the second limiting groove 214, allowing the body 212 of the retaining member 21 to be released from the drive hole 13 of the connecting member 10 for replacement of the brush assembly 20.
