Summary:A disposable toothbrush of the present invention comprises a head unit (110), toothbrush bristles (120), a handle unit (130), and a toothpaste supplying unit (140). The head unit (110) forms a plurality of implemented pores on an upper surface, forms a toothpaste supplying hole (112) which is formed by penetrating an upper surface from the lower surface in a central part, and forms 2-6 fixed holes (113) on a lower surface. The toothbrush bristles (120) are implanted in the pores. The handle unit (130) is connected to the head unit (110). The toothpaste supplying unit (140) includes: a head touching unit (141); a protruding unit (142); a toothpaste accommodating unit (143); a fixed protrusion (144); a toothpaste supply protruding unit (145); and a cutting unit (146). The head touching unit (141) is bonded to a lower surface of the head unit (110). The protruding unit (142) is formed to protrude in a dome shape in a lower part of the head touching unit (141). The toothpaste accommodating unit (143) forms a sealed space between the head touching unit (141) and the protruding unit (142) and accommodates toothpaste. The fixed protrusion (144) is provided in the head touching unit (141), is inserted into each of the fixed holes (113), and fixes the head touching unit (141) to a lower surface of the head unit (110). The toothpaste supply protruding unit (145) is inserted into the toothpaste supply hole (112) and is connected to the toothpaste accommodating unit (143). The cutting unit (146) is provided in an end part of the toothpaste supply protruding unit (145), is cut by pressure by pressing the protruding unit (142), supplies the toothpaste accommodated in the toothpaste accommodating unit (143) to the toothpaste supplying hole (112) through the toothpaste supply protruding unit (145), and supplies the toothpaste to the toothbrush bristles (120). The present invention can prevent wastage of the toothpaste. 본 발명의 일회용 칫솔은, 상면에 다수의 식모공이 형성되고, 중앙부위에 상기 하면으로부터 상면을 관통하여 형성되는 치약공급공(112)이 형성되며, 하면에 2개 내지 6개의 고정공(113)이 형성되는 헤드부(110); 상기 식모공에 식재된 칫솔모(120); 상기 헤드부(110)와 연결된 손잡이부(130); 상기 헤드부(110)의 하면에 접하는 헤드접촉부(141)와, 상기 헤드접촉부(141)의 하부에 돔형태로 돌출되도록 형성되는 돌출부(142)와, 상기 헤드접촉부(141)와 상기 돌출부(142) 사이의 밀폐된 공간을 이루며 치약이 수용되는 치약수용부(143)와, 상기 헤드접촉부(141)에 구비되고 상기 고정공(113)에 각각 삽입되어 상기 헤드접촉부(141)가 상기 헤드부(110)의 하면에 고정되도록 하는 고정돌기(144)와, 상기 치약공급공(112)에 삽입되며 상기 치약수용부(143)와 연통되는 치약공급용 돌기부(145)와, 상기 치약공급용 돌기부(145)의 단부부위에 구비되며 상기 돌출부(142)의 누름에 의한 압력에 의해 절취되어 상기 치약공급용 돌기부(145)를 통해 상기 치약수용부(143)에 수용된 치약을 상기 치약공급공(112)으로 공급되도록 함으로써 상기 칫솔모(120)에 공급되도록 하는 절취부(146)로 이루어지는 치약공급부(140);를 포함하여 이루어지는 것을 특징으로 한다.
