AI Technical Summary

Benefits of technology

The present invention provides a toothbrush with replaceable brush heads that are easily stored, securely and fixedly mounted without the need for separation, and can be quickly replaced with new ones as needed. The brush heads are designed to be tightly and closely fixed when mounted, allowing for effective brushing of teeth. The technical effect of the invention is to improve the user experience, convenience, and cost-effectiveness.

Problems solved by technology

In the case of the toothbrush, as a predetermined time elapses, the brush hairs of the toothbrush are spread or abraded, so that the user may not effectively brush the teeth with the toothbrush.

Accordingly, the user must replace the entire portion of the toothbrush with new one, which may be not economical.

However, according to the cited reference 1, as the toothbrush has a complex structure, the manufacturing cost may be increased.

In addition, according to the cited reference 1, a user may not only feel inconvenient in use, but also must replace the entire portion of the toothbrush including brush hairs, so that loss may be greatly caused in an economical aspect.

According to the cited reference 2, although the toothbrush has a simpler structure, the storage of the toothbrush is cumbersome and inconvenient.

In addition, when toothpaste sticks to a coupling part, the toothpaste may not be easily separated from the coupling part.

According to the cited reference 3, since the entire portion of the first head having the size corresponding to that of the body must be replaced with new one, loss may be great in the economical aspect.
