The portable interdental brush according to the present invention is easy to carry because the cleaning liquid is accommodated therein, the upper part is formed with an assembly projection part from which the cleaning liquid flows out, and the lower part is formed with an injection hole filled with the cleaning liquid, After the injection, the cleaning liquid tube to which the injection hole lid for closing the injection hole is attached and an assembly hole into which the assembly protrusion of the cleaning liquid tube is inserted and assembled are formed in the lower part and assembled to the assembly protrusion of the cleaning liquid tube. The upper part includes a brush body with a brush fixing part fixed, and when used, the cleaning liquid tube is rotated to open and the cleaning liquid tube is pushed, so that the brush can be used even when the cleaning liquid flows out. Since there is no shaking of the fixed brush body, it can be used conveniently. After use, turning the cleaning solution tube in the opposite direction blocks the cleaning solution from flowing out. The injection hole lid is fixed to the lower end of the cleaning solution tube so that it can be easily controlled and injection of the cleaning solution is easy.Injection of the cleaning solution becomes easy, mass production becomes possible, and the manufacturing cost is low. Convenient to do. [Selection] Figure 2本発明による携帯用歯間ブラシは、洗浄液が収納されて携帯が簡単になり、上部には洗浄液が流出される組立突出部が形成され、下部には洗浄液が充填される注入孔が形成され、注入後には注入孔を閉鎖させる注入孔の蓋が取り付けされた洗浄液チューブと、前記洗浄液チューブの組立突出部が挿入されて組み立てられる組立孔が下部に形成されて前記洗浄液チューブの組立突出部に組み立てられ、上部にはブラシ固定部が固定されたブラシ本体を含み、使用する場合には、洗浄液チューブを回して開放させて洗浄液チューブを押すと、洗浄液が流出される状態で使用してもブラシが固定されたブラシ本体の揺れがないので、便利に使用が可能になり、使用後には洗浄液チューブを反対方向に回すと、洗浄液の流出が遮断されて洗浄液の流出が容易に制御され、洗浄液の注入が容易であるように洗浄液チューブの下端に注入孔の蓋を固定させて洗浄液の注入が容易になり、大量生産が可能になって製造コストが安価になり、使用するのに便利である。【選択図】図２
