FIG. 2 is a view for explaining an outline of a water circuit, an air circuit, and an electric circuit in a handpiece drive unit having a built-in electric drive mechanism for dental use according to the present invention. the inner, air circuit 9 _first air turbine _drive, air circuit 9 ₂ for spray (mixture of water and _air), the water circuit 9 ₃ etc. is provided for spraying, conventional controls foot controller to, by adjusting the air volume of the supplied air circuit 9 ₁ the air turbine, and controlling the rotational speed of the air turbine, in tooth cutting, mixing of the air circuit 9 _2, air and water from the water circuit 9 ₃ to the cutting unit Is sprayed to cool the cutting part.
[0014]
Also in the present invention, the foot controller is operated as described above, and the air for driving the turbine and the air and water for spraying are supplied to the drive unit body 10 in the same manner as in the conventional air turbine operation. As described above, when the air for driving the air turbine is supplied through the instrument hose 9 as described above, the drive unit main body 10 detects that the air has been supplied, and water circuit communicates with the air circuit 13 ₂ and the water circuit 13 ₃ of the motor built-in micro engine 14 instrument hose 13, from the micro-engine 14, is injected spray for tooth cutting unit cooling, at the same time, the handpiece 14 supplied to the motor section of air for cooling the motor incorporated in the head portion through the air circuit 13 _1.
