Claims

[Scope of claim for utility model registration] 1. Controlling the rotation of an abrasive material attached to a handpiece used for cutting tooth models or teeth in the oral cavity, and the release of tip air and spray water from the handpiece by foot operation. In a foot controller for a dental treatment device that is used by being connected to a dental treatment device, one pedal side is equipped with compressed air that controls the rotation of the abrasive material attached to the handpiece depending on the amount of pedal depression. At least a control valve with a relief to control the compressed air supplied to the air turbine operated by the DC motor and a variable resistor to control the voltage supplied to the DC motor are installed. A three-way valve is provided which opens when stepped on to supply tip air to the handpiece, and an air pipe line in which the control valve with relief is installed and an air line in which the three-way valve is installed. Air pipes branched from the dental treatment apparatus are connected to each other, and when the two pedals are pressed together, compressed air is supplied from both air pipes, and the water provided in the dental treatment apparatus is supplied with compressed air. A foot controller for a dental treatment device, characterized in that the on-off valve is equipped with an on-off valve for supplying pilot air. 2. The foot controller for a dental treatment device according to claim 1, wherein the control valve with relief is a pressure reducing valve with relief that adjusts compressed air pressure. 3. The foot controller for a dental treatment device according to claim 1, wherein the control valve with relief is a throttle valve with relief that adjusts the flow rate of compressed air.
