PURPOSE: A multi-user dental cleaning device is provided to be usable for multiple users at the same time, and to be operated or stopped by a one-touch operation. CONSTITUTION: A multi-user dental cleaning device includes an inlet port(110), a water current sensor(120), a pulsation pump(130), a nozzle gun(140), and a control unit(150). The inlet port is supplied with cleaning water from a cleaning water supply source(10), and makes the cleaning water to flow into a cleaning water supply flow channel(20). The water current sensor is installed on the cleaning water supply flow channel, in which the cleaning water flows, and senses the flow of the cleaning water. The pulsation pump is connected to the rear end of the water current sensor on the cleaning water supply flow channel; is supplied with the cleaning water; and provides pressure for the cleaning water, which is supplied by the operation according to a control signal, to be pulsated at a regular interval and discharged. The nozzle gun is connected to the rear end of the pulsation pump to discharge the cleaning water, and equipped on one side with an opening and closing switch(143) which selectively opens or closes an inner pipe(146) that is connected with the cleaning water supply flow channel. The control unit is signal-connected with the water current sensor and the pulsation pump in order to output a control signal, which operates the pulsation motor according to water current sensing data that is transferred from the water current sensor, to the pulsation pump. |
