The present invention relates to a multi-piece bristles replacement toothbrush, and more particularly to a combined toothbrush structure having a collection of bristles.

In order to meet the different human tooth structure and different cleaning needs, manufacturers will continue to develop a variety of toothbrushes with different types of bristles according to various needs, in order to meet the needs of use.

Generally, the toothbrushes sold in the market are mainly made of plastic materials, and their service life is generally from one month to three months. When the brush on the toothbrush is worn to a certain extent, the integrally formed toothbrush must be discarded. The new toothbrush was purchased to replace it. As a result, a large number of discarded toothbrushes could not be decomposed for many years, and thus became a large amount of garbage that would damage the environment and seriously harm the environment.

Based on the above problems, a replaceable toothbrush has emerged. For example, in the case of the Republic of China No. M277340, a combined toothbrush is disclosed. When the bristles on the brush head are damaged to a considerable extent, only a new brush needs to be replaced. The head element can be used as the toothbrush body can be repeatedly used repeatedly to reduce the harm to the environment.

Regardless of whether it has the function of a replaceable brush head, the manufacturer has spared no effort in improving the design of the bristles. In order to achieve different cleaning or care needs at the same time, many bristles on the toothbrush are designed with a variety of different bristles, such as bristles of different thickness, length and hardness on the toothbrush, as well as the arrangement and selection of the bristles. The materials are also quite elegant.

However, many toothbrushes that use composite bristles and are advertised as having a variety of cleaning and care effects are not ideal for use because the various bristles are interlaced and mixed, not only failing to achieve the desired cleaning and care results, but also some Because the toothbrush bristles are not properly designed, it can cause damage to the teeth and gums.
