Claims

[Claims for Utility Model Registration] 1. Commonly used by a constant-speed air-driven handpiece that is used with a substantially constant air flow rate for a treatment tool and a variable-speed air-driven handpiece that is used with an adjustable air flow rate. A drive air control device comprising: a compressed air source, a starting air cutoff valve, a flow rate adjustment valve, a constant speed variable speed switching valve, and connecting these valves, the compressed air source, and the handpiece. It consists of an air pipe, a foot controller that operates an air cutoff valve for startup, and a flow rate adjustment valve, and the constant speed variable speed switching valve allows a constant speed air-driven handpiece and a variable speed air-driven handpiece to be operated. If you select one of these and select a constant speed air-driven handpiece, the foot controller will operate the
When the starting air shutoff valve is opened to drive the constant speed air-driven handpiece and a variable speed air-driven handpiece is selected, the starting air shutoff valve is opened by operating the foot controller. A dental air-driven hand that opens an air cutoff valve to drive the variable speed air-driven handpiece and adjusts the flow rate of air flowing through the flow rate adjustment valve linked to the operation amount of the foot controller. Piece control device. 2. A drive air control device that is commonly used by a constant speed air-driven handpiece that is used with a constant air flow rate to a treatment tool and a variable speed air-driven handpiece that is used with an adjustable air flow rate, Connect the compressed air source, the air cutoff valve for startup, the flow rate adjustment valve, the servo motor system that controls the flow rate adjustment valve, the constant speed variable speed changeover switch, these valves, the handpiece, and the air source. air piping,
It consists of a foot controller that operates the electric switch of the air cutoff valve for startup and the input variable resistor of the servo motor system of the flow rate adjustment valve. If you select either a variable-speed air-driven handpiece or a constant-speed air-driven handpiece, you can operate the foot controller to
When the air shutoff valve for the startup is opened and the constant speed air-driven handpiece is selected, and the variable speed air-driven handpiece is selected, the air shutoff valve for the startup is activated by operating the foot controller. A dental air drive device that opens an air cutoff valve to drive the variable speed air drive handpiece and adjusts the flow rate of air flowing through the flow rate adjustment valve linked to the operation amount of the foot controller. Handpiece control device.
