GAS-LIQUID SEPARATOR FOR DENTISTRY, SUCTION DEVICE FOR DENTISTRY, SUCTION SYSTEM FOR DENTISTRY AND GAS-LIQUID SEPARATION METHOD IN DENTISTRY

摘要

PROBLEM TO BE SOLVED: To provide a gas-liquid separator for dentistry achieving space-saving and having high installation flexibility.;SOLUTION: The gas-liquid separator for dentistry includes: a tank (1t) having a suction port (1a) and capable of storing liquid flowing from the suction port (1a); a connecting port (1b) provided on an upper part of the tank (1t); a pump (3) connected to a lower part of the tank (1t); and a check valve (7) provided at a discharge route (4c) connected to the pump (3) and passing only the flow from the pump (3). A negative pressure generator (53) is connected to the connecting port (1b) and, when an air-liquid mixture body (AL) is sucked from the suction port (1a) into the tank (1t) by operation of the negative pressure generator (53), the gas-liquid separator downward separates a liquid (LQ) of the air-liquid mixture body (AL) by dead weight and can discharge it through the check valve (7) by the operation of the pump (3).;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
