Technical Field
The utility model relates to a shaver, in particular to a multi-blade module wheel-changing type manual shaver.
Background
The shaver is a personal care product which is common in daily life, belongs to a self-service tool, and is mainly used for shaving beards and body hair. Generally, a shaver may be classified into an electric shaver and a manual shaver.
The electric shaver always has a certain distance with the skin to protect the skin from being cut due to the cutter head, the cutter mesh and the like, so that the clean shaving experience can not be achieved ever though the electric shaver is safe. In contrast, a manual shaver with a frequently replaced shaving head is sharper and causes less damage to hair follicles during shaving, which can be visually compared by the cross-sections of two shaving beards.
In view of the fact that the shaving heads of a manual shaver need to be replaced frequently, users often need to prepare multiple sets of shaving heads for use. The spare cutter heads commonly adopted in the prior art are all independent of the shaver, a storage container is additionally provided, and the old cutter heads are manually disassembled and replaced after being taken out from the storage container during replacement. Obviously, the storage mode and the replacement mode of the cutter head in the prior art have higher challenges for user experience, and need to be improved urgently.
