The present invention relates to an easy-to-clean biodegradable toothbrush, and more particularly, to an easy-to-clean biodegradable toothbrush in which the unit main body in which toothbrush bristles are implanted is made of an elastic body, so that cleaning between the toothbrush bristles is easy, and the toothbrush The handle and the toothbrush head are made of biodegradable resin, which shows excellent biodegradability, and the application of toothbrush bristles which emit negative ions and have excellent antibacterial properties shows excellent storage properties.

A toothbrush is an oral hygiene tool used with toothpaste. It is said that the origin of the toothbrush made of brushes used today is that the ancient Chinese embedded the bristles of pigs living in cold regions into handles made of bamboo or bone. Made, and it was spread to Europe and developed to this day. Various methods for hygienically managing toothbrushes have been continuously researched from the introduction of nylon toothbrushes with less concern about bacterial growth when nylon was introduced in the 1930s to the present.

Since people put the toothbrush directly into the oral cavity and use it, keeping the toothbrush cleanly is very important for personal hygiene. Usually, in order to keep the toothbrush hygienically, the toothbrush is hung on a toothbrush holder after brushing the teeth.

However, before keeping the toothbrush cleanly, the bristles formed on the toothbrush should be kept clean at first, and in conventional toothbrushes, the unit body in which the bristles are implanted is made of a material without flexibility, so residues remain in the bristles. It is not easy to clean when there are foreign objects, etc.

In addition, in the past, when the bristles of the toothbrush were worn out, the entire toothbrush had to be disposed of, and the material of the toothbrush was composed of non-biodegradable synthetic resin, resulting in waste of resources and environmental pollution during disposal.
