Description

Technical Field

[0001] This utility model relates to a small handle shaving component. Background Technology

[0002] Currently, there are two types of razors on the market: electric and manual. Generally speaking, electric razors are more efficient and relatively safer, but they are not as effective at shaving as manual razors. Manual razors, on the other hand, are effective at shaving, but because the blades are directly shaving the skin, it is easy to cut the skin if you are not careful when shaving long hair. Manual razors are generally used mainly for shaving short hair.

[0003] The main body of existing electric shavers is relatively large, and the main body also serves as the handle; while the handle of manual shavers is relatively small. Electric shavers and manual shavers are usually separate. For people with long beards, they usually need to buy both a reciprocating electric shaver with comb teeth and a manual shaver, which undoubtedly increases costs.

[0004] This utility model is a technical solution based on this situation, which uses a small handle and is combined with both electric and manual shaving heads.

[0005] Currently, electric shavers on the market typically use a snap-fit ​​connection between the shaver head and handle for easy head replacement. In recent years, to further facilitate head replacement, a magnetic connection structure has emerged, as exemplified by patent technology (CN222135045U) entitled "A Hidden Magnetic Shaver Structure." Magnetic connections between the shaver head and handle are generally used in larger shaver bodies and heads, where ample space allows for magnet placement. However, for smaller handles with an outer diameter of no more than 18mm, space constraints necessitate a rotating snap-fit ​​connection. Since these smaller handles also share a manual shaver head, whose blades are exposed on the top, manual shaver head replacement can easily result in cuts as the hand slips across the blades. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a simple small handle shaving assembly that allows for the replacement of electric or manual shaving heads via magnetic attraction.

[0007] To solve the above-mentioned technical problems, this utility model provides a small handle shaving assembly, including a handle, an electric shaving head, and a manual shaving head.
