Summary:The present invention relates to an air valve applied to a medical instrument as an air valve used in a medical instrument, which comprises: a valve body having an inlet and an outlet for air to enter and exit formed on the upper surface while having a threaded part formed on the inner lower part; a core body inserted into the valve body and screwed together while having a coupling block formed integrally in the center of the upper surface; a bobbin inserted and fixed within the core body and having a coil wound around the outer circumference thereof; a core inserted into the bobbin and screwed to the coupling block of the valve body; a support ring provided to be seated on the upper surface of the core body within the valve body; a leaf spring mounted on the upper surface of the support ring; a plunger closely fixed to the bottom of the leaf spring and spaced apart from the core body; and a packing member penetrating the leaf spring and the plunger and coupled and fixed, wherein the upper surface thereof is provided in contact with the discharge port of the valve body. As the leaf spring bends due to the magnetic force generated from the core body and the packing member moves, the air valve is disposed to make the inlet communicate with the outlet of the valve body. 본 발명은 의료기기에 적용되는 에어 밸브에 관한 것으로, 의료기기에 사용되는 에어 밸브로서, 상면에 에어가 출입되는 흡입구와 토출구가 형성되는 한편 내측 하부에는 나사부가 형성되는 밸브바디; 밸브바디 내에 삽입되어 나사 결합되는 한편 그 상면 중앙에는 결합블록이 일체형으로 형성되는 코어바디; 코어바디 내에 삽입되어 고정되는 한편 그 외주면에는 코일이 권취되어 구비되는 보빈; 보빈 내로 삽입되어 밸브바디의 결합블록에 나사 결합되게 구비되는 코어; 밸브바디 내에서 코어바디의 상면에 안착되게 구비되는 서포트링; 서포트링의 상면에 안착되어 구비되는 판스프링; 판스프링의 하면에 밀착 고정되어 코어바디와 이격되게 구비되는 플런저; 판스프링과 플런저를 관통하여 결합 고정되고 그 상면은 밸브바디의 토출구에 접하여 구비되는 패킹부재;를 포함하여, 코어바디에서 발생되는 자기력에 의해 판스프링이 휘어짐에 따라 패킹부재가 이동되면서 밸브바디의 흡입구와 토출구를 연통시키도록 구비되는 에어 밸브를 제공한다.
