| I.P Abstract & Summary |
A portable interdental toothbrush is provided that can be carried conveniently since a cleaning solution tube stays in a sealed state when carried without using it, which makes it convenient to use. When using the interdental toothbrush, an engaging protrusion fixed to an engaging portion is released to wet a brush with the cleaning solution filled in the cleaning solution tube through the discharge hole by pulling the brush body. Due to the features, the structure is simple, the production is easy, and production cost is low, thereby allowing any user to use it, and promoting the dental and oral health for citizens. |
