Description

  The present invention relates to a replaceable toothbrush, and particularly relates to a hooking structure of a replaceable toothbrush and the brush.

At present, most of the toothbrushes on the market are made of plastic material, and their service life is usually about three months. The toothbrush bristles continue to rub against the teeth, causing a certain amount of wear. However, since the cleaning function is reduced and bacteria are likely to be generated, it must be discarded. However, this is a waste of resources and not good for environmental protection.

The industry has designed toothbrushes that replace brushes to effectively ameliorate the aforementioned problems. It mainly consists of a grip and a brush connected to the grip. The brush includes a pedestal connected to the grip and a toothbrush piece in which brush bristles are planted. Among them, the pedestal and the toothbrush piece have a fitting structure in which the base and the toothbrush piece are fitted to each other to form a replaceable brush toothbrush.
