통상적으로 부항은 펌프의 왕복운동에 의해 대기압 이하의 음압이 발생되고, 이러한 압력차를 이용하여 체액을 몸바깥으로 배출하는데 사용되는 장치로서, 주로 어혈, 콧물, 가래를 포함하는 체액배출용으로 널리 사용된다.In general, the cupping is a negative pressure below the atmospheric pressure is generated by the reciprocating motion of the pump, the device used to discharge the body fluids out of the body by using the pressure difference, it is widely used for the discharge of body fluids including mainly blood, runny nose, sputum Used.

예컨대, 부항은 부항용기의 측면 혹은 상부에 밸브가 구비되고, 밸부상에 펌프를 연결하여 공기를 흡입하되, 밸브는 부항용기의 내부공기 배출은 허용하면서 유입은 차단하여 펌프를 분리한 후에도 부항용기 내부의 진공상태가 견고하게 유지되도록 하는 중요한 구성요소이다.For example, the cupping vessel is provided with a valve on the side or top of the cupping vessel, and connects a pump on the valve portion to suck in air, but the valve allows the inside air of the cupping vessel to be discharged while the inlet is blocked to separate the pump even after separating the pump. It is an important component that keeps the vacuum inside.

이에 종래에 개시된 부항을 살펴보면, 공개실용신안 공고번호 실1989-3064호에서 밸브체의 손잡이와 삽입관을 연결하고 있는 연결관의 외주면 좌. 우측에 수평 방향으로 일정한 간격부분으로 배기 통로에 관통되게 절결 형성된 틈새를 대칭 형성하여 배기통로와 연결되면서 관통되도록 구성함으로서 부항기의 진공상태를 유지시킬 수 있고, 또한 손쉽게 진공상태를 해제할 수 있도록 하고 있다.Looking at the prior art disclosed in this, the left side of the outer circumference of the connecting pipe connecting the handle and the insertion pipe of the valve body in the Utility Model Publication No. 1989-3064.

둘째, 밸브의 틈새(절개선)와 부항 내부공간이 연통되도록 밸브 중심에 배기통로가 필히 구비되어야 함에 따라 밸브의 직경 축소에 한계가 따랐고, 이는 부항의 소형화에 가장 큰 걸림돌이 되는 폐단이 따랐다.Second, the exhaust passage must be provided at the center of the valve so that the gap between the valve (incision line) and the inner space of the cupping was inevitably limited, resulting in a limitation in reducing the diameter of the valve, which was the biggest obstacle to the miniaturization of the cupping.

이에 따라 본 고안은 상기한 문제점을 해결하기 위해 착안 된 것으로서, 보다 상세하게는 사용중 국부적인 변형으로 인한 압력누수 및 압력조절기능상실을 포함하는 작동불량을 방지하고, 또 부항용기와 더불어 사이즈의 소형화가 가능한 부항용 밸브를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been conceived to solve the above problems, and more particularly, to prevent malfunctions, including pressure leakage and loss of pressure control due to local deformation during use, and further downsizing the size with the cupping container It is an object of the present invention to provide an actuating valve.

본 고안은 부항용 밸브에 관련되며, 이때 부항용 밸브는 펌프와 연결되어 부항내부 공기의 배출은 허용하되, 유입은 차단하는 역류방지밸브로서, 장시간 반복사용에도 압력누수, 압력 조절기능상실을 포함하는 작동불량이 방지 및 사이즈의 소형화가 가능하도록 밸브설치홀(10), 밸브본체(20)를 포함하여 주요구성으로 이루어진다.The present invention relates to a cupping valve, in which the cupping valve is connected to a pump to allow the discharge of the air inside the cupping, but prevents the inflow, and prevents inflow. It consists of the main configuration including the valve installation hole 10, the valve body 20 to prevent malfunction and to downsize the size.

[실시예 1]Example 1

본 고안에 따른 밸브설치홀(10)은 부항용기(1)의 일측에 관통형성된다. 밸브설치홀(10)은 후술하는 탄성바(22)가 끼움결합되도록 부항용기(1)의 외측에서 내측으로 관통형성된다. The valve installation hole 10 according to the present invention is formed through one side of the cupping container (1). The valve installation hole 10 is formed to penetrate inward from the outside of the cupping container 1 so that the elastic bar 22 to be described later is fitted.

그리고 밸브설치홀(10)과 인접하는 부항용기의 내ㆍ외주면은 수평면으로 형성된다. 이에 밸브설치홀(10)을 통하여 끼움결합된 밸브본체(20)의 후크(22a)와 확장캡(24)이 부항용기(1)의 밸브설치홀(10)과 인접하는 부항용기(1)의 내ㆍ외주면에 형성된 수평면에 긴밀하게 면접되어 기밀성이 향상된다.The inner and outer circumferential surfaces of the cupping container adjacent to the valve installation hole 10 are formed in a horizontal plane. Accordingly, the hook 22a and the expansion cap 24 of the valve body 20 fitted through the valve mounting hole 10 of the cupping container 1 adjacent to the valve mounting hole 10 of the cupping container 1 are disposed. The airtightness is improved by closely interviewing the horizontal surfaces formed on the inner and outer peripheral surfaces.

또한, 본 고안에 따른 밸브본체(20)는 밸브설치홀(10)에 삽입되어 일단에 구비되는 후크(22a)에 의해 결속되고 외주면에 공기유로(22b)가 형성되는 탄성바(22)와, 탄성바(22)의 다른 일단에 확장형성되어 부항용기(1)의 외주면에 밀착되는 확장캡(24)이 구비된다.In addition, the valve body 20 according to the present invention is inserted into the valve installation hole 10 is bound by the hook 22a provided at one end and the elastic bar 22 is formed in the outer circumferential surface air flow path 22b, An expansion cap 24 is formed on the other end of the elastic bar 22 to be in close contact with the outer circumferential surface of the cupping container 1.

밸브본체(20)는 고무, 실리콘을 포함하는 탄성력이 우수한 재질로 형성되고, 탄성바(22)를 통하여 밸브설치홀(10)에 끼움결합된다. 탄성바(22)는 밸브설치홀(10)의 내경사이즈를 고려하여 억지끼움결합되도록 공차가공되고, 밸브설치홀(10)에 삽입된 상태로 후크(22a)에 의해 이탈이 방지된다. 후크(22a)는 탄성바(22)의 직경대비 확장형성되고, 밸브설치홀(10)상으로 초기진입이 용이하도록 선단부가 반구형 또는 원추형으로 형성된다.The valve body 20 is formed of a material having excellent elastic force including rubber and silicon, and is fitted into the valve installation hole 10 through the elastic bar 22. The elastic bar 22 is processed tolerantly fit in consideration of the inner diameter size of the valve installation hole 10, and is prevented from being separated by the hook 22a in a state of being inserted into the valve installation hole 10. The hook 22a is formed to expand relative to the diameter of the elastic bar 22, and the front end portion is formed in a hemispherical shape or a conical shape to facilitate the initial entry into the valve installation hole 10.

그리고, 탄성바(22)는 밸브설치홀(10)에 삽입된 상태로 외주면에 형성되는 공기유로(22b)를 통하여 공기가 이송되되, 공기유로(22b)는 1~4개소에 오목하게 함몰형성되고, 확장캡(24)에 의해 마감되어 진공펌프의 흡입력이 작용시 부항용기(1)의 내부공기 배출은 허용되고, 유입은 차단하게 된다.In addition, the elastic bar 22 is transferred to the air through the air flow passage 22b formed on the outer circumferential surface of the elastic bar 22 is inserted into the valve installation hole 10, the air flow passage 22b is formed recessed in 1 to 4 places. When the suction force of the vacuum pump is acted upon by the expansion cap 24, the internal air discharge of the cupping container 1 is allowed, and the inflow is blocked.

즉, 밸브본체(20)가 밸브설치홀(10)에 설치된 상태로 탄성바(22) 및 확장캡(24)에서 각각 작용하는 이중 탄성력에 의해 공기유로(22b)가 마감됨에 따라 사용중 확장캡(24)의 들뜸현상으로 인한 압력누수 및 압력 조절기능상실을 포함하는 작동불량이 방지된다.That is, as the air flow passage 22b is closed by the double elastic force acting on the elastic bar 22 and the expansion cap 24 in a state in which the valve body 20 is installed in the valve installation hole 10, the expansion cap during use ( Preventing malfunctions including pressure leakage and loss of pressure regulation due to the lifting of 24).

이때, 확장캡(24)은 중심에서 가장자리부로 갈수록 두께가 얇게 형성된다. 이에 확장캡(24)은 가장자리부로 갈수록 얇아지는 두께로 인해 유연성 및 탄성변형폭이 형상됨에 따라 부항용기(1)와의 밀착성이 향상되고, 또 사용중 가장자리부분에 이물질이 잔류하거나 일부손상되더라도 확장캡(24)의 자체탄성변형에 의해 손상부분이 유연하게 보상되는 이점이 있다.At this time, the expansion cap 24 is formed thinner from the center to the edge portion. Accordingly, the expansion cap 24 has improved flexibility and elasticity with the cupping container 1 due to the flexibility and elastic deformation width due to the thickness becoming thinner toward the edge, and the expansion cap (even if foreign matter remains or partially damaged at the edge part during use) There is an advantage that the damaged part is flexibly compensated by the self-elastic deformation of 24).

또한, 상기 확장캡(24)은 부항용기(1)와 면접되는 저면에 종단면형상이 아치형으로 형성된 밀착탄지부(26)가 구비된다. 밀착탄지부(26)는 확장캡(24)의 저면이 탄성바(22)가 형성된 중심에서 가장자리부로 갈수록 하향절곡되어 확장캡(24)의 밀착력이 가장자리부로 집중되는 구조를 가진다.In addition, the expansion cap 24 is provided with a close contact portion 26 is formed in an arcuate longitudinal section on the bottom surface in contact with the cupping container (1). The close contact portion 26 has a structure in which the bottom surface of the expansion cap 24 is bent downward from the center where the elastic bar 22 is formed to the edge portion so that the adhesive force of the expansion cap 24 is concentrated to the edge portion.

즉, 밀착탄지부(26)에 의해 확장캡(24)의 저면이 부항용기(1)의 외주면과 전체적으로 면접되지 않고, 가장자리부분이 국부적으로 밀착됨에 따라 사용중 압력누수를 포함하는 작동불량이 방지된다.That is, the bottom surface of the expansion cap 24 is not entirely interviewed with the outer circumferential surface of the cupping container 1 by the close contact portion 26, and the edge portion is locally intimately contacted to prevent a malfunction including pressure leakage during use. .

또, 확장캡(24)의 선단부를 방향에 무관하게 어느 일측에서 가압하면 밀착탄지부(26)가 부항용기(1) 표면으로부터 이격되어 외부공기가 유입되므로 진공압력조절이 간편하게 수행되는 이점이 있다.
In addition, if the front end portion of the expansion cap 24 is pressed in any side irrespective of the direction, the close contact portion 26 is separated from the cupping vessel 1 surface, so that the outside air flows, there is an advantage that the vacuum pressure control is easily performed. .

[실시예 2][Example 2]

본 고안에 따른 밸브설치홀(10)은 부항용기(1)의 일측에 관통형성되고, 내주면에 공기유로(12)가 형성된다. 밸브설치홀(10)은 후술하는 탄성바(22)가 끼움결합되도록 부항용기(1)의 외측에서 내측으로 관통형성되고, 내주면에 공기유로(12)가 1~4개소에 형성된다.The valve installation hole 10 according to the present invention is formed through one side of the cupping container 1, the air passage 12 is formed on the inner peripheral surface. The valve installation hole 10 is formed to penetrate from the outer side of the cupping container 1 to the inner side so that the elastic bar 22 to be described later is fitted, and the air passages 12 are formed at one to four places on the inner circumferential surface thereof.

그리고 밸브설치홀(10)과 인접하는 부항용기의 내ㆍ외주면은 수평면으로 형성된다. 이에 밸브설치홀(10)을 통하여 끼움결합된 밸브본체(20)의 후크(22a)와 확장캡(24)이 부항용기(1)의 밸브설치홀(10)과 인접하는 부항용기(1)의 내ㆍ외주면에 형성된 수평면에 긴밀하게 면접되어 기밀성이 향상된다.The inner and outer circumferential surfaces of the cupping container adjacent to the valve installation hole 10 are formed in a horizontal plane. Accordingly, the hook 22a and the expansion cap 24 of the valve body 20 fitted through the valve mounting hole 10 of the cupping container 1 adjacent to the valve mounting hole 10 of the cupping container 1 are disposed. The airtightness is improved by closely interviewing the horizontal surfaces formed on the inner and outer peripheral surfaces.

또한, 본 고안에 따른 밸브본체(20)는 밸브설치홀(10)에 삽입되어 일단에 구비되는 후크(22a)에 의해 결속되는 탄성바(22)와, 탄성바(22)의 다른 일단에 확장형성되어 부항용기(1)의 외주면에 밀착되는 확장캡(24)이 구비된다.In addition, the valve body 20 according to the present invention is inserted into the valve installation hole 10 is extended to the elastic bar 22 and the other end of the elastic bar 22 is bound by the hook 22a provided at one end. Is formed is provided with an expansion cap 24 in close contact with the outer peripheral surface of the cupping container (1).

밸브본체(20)는 고무, 실리콘을 포함하는 탄성력이 우수한 재질로 형성되고, 탄성바(22)를 통하여 밸브설치홀(10)에 끼움결합된다. 탄성바(22)는 밸브설치홀(10)의 내경사이즈를 고려하여 억지끼움결합되도록 공차가공되고, 밸브설치홀(10)에 삽입된 상태로 후크(22a)에 의해 이탈이 방지된다. 후크(22a)는 탄성바(22)의 직경대비 확장형성되고, 밸브설치홀(10)상으로 초기진입이 용이하도록 선단부가 반구형 또는 원추형으로 형성된다.The valve body 20 is formed of a material having excellent elastic force including rubber and silicon, and is fitted into the valve installation hole 10 through the elastic bar 22. The elastic bar 22 is processed tolerantly fit in consideration of the inner diameter size of the valve installation hole 10, and is prevented from being separated by the hook 22a in a state of being inserted into the valve installation hole 10. The hook 22a is formed to expand relative to the diameter of the elastic bar 22, and the front end portion is formed in a hemispherical shape or a conical shape to facilitate the initial entry into the valve installation hole 10.

그리고, 탄성바(22)는 일단에 구비되는 확장캡(24)이 부항용기(1)의 외주면에 밀착되어 상기 밸브설치홀(10)의 공기유로(12)가 마감됨에 따라 진공펌프의 흡입력이 작용시 부항용기(1)의 내부공기 배출은 허용되고, 유입은 차단된다.In addition, the elastic bar 22 has an expansion cap 24 provided at one end thereof in close contact with the outer circumferential surface of the cupping container 1 so that the suction force of the vacuum pump is increased as the air flow passage 12 of the valve installation hole 10 is closed. During operation, the discharge of the internal air of the cupping container 1 is allowed, and the inflow is blocked.

즉, 밸브본체(20)가 밸브설치홀(10)에 설치된 상태로 탄성바(22) 및 확장캡(24)에서 각각 작용하는 이중 탄성력에 의해 공기유로(12)가 마감됨에 따라 사용중 확장캡(24)의 들뜸현상으로 인한 압력누수 및 압력 조절기능상실을 포함하는 작동불량이 방지된다.That is, as the air flow passage 12 is closed by the double elastic force acting on the elastic bar 22 and the expansion cap 24 in a state in which the valve body 20 is installed in the valve installation hole 10, the expansion cap during use ( Preventing malfunctions including pressure leakage and loss of pressure regulation due to the lifting of 24).

이때, 확장캡(24)은 중심에서 가장자리부로 갈수록 두께가 얇게 형성된다. 이에 확장캡(24)은 가장자리부로 갈수록 얇아지는 두께로 인해 유연성 및 탄성변형폭이 형상됨에 따라 부항용기(1)와의 밀착성이 향상되고, 또 사용중 가장자리부분에 이물질이 잔류하거나 일부손상되더라도 확장캡(24)의 자체탄성변형에 의해 손상부분이 유연하게 보상되는 이점이 있다.At this time, the expansion cap 24 is formed thinner from the center to the edge portion. Accordingly, the expansion cap 24 has improved flexibility and elasticity with the cupping container 1 due to the flexibility and elastic deformation width due to the thickness becoming thinner toward the edge, and the expansion cap (even if foreign matter remains or partially damaged at the edge part during use) There is an advantage that the damaged part is flexibly compensated by the self-elastic deformation of 24).

또한, 상기 확장캡(24)은 부항용기(1)와 면접되는 저면에 종단면형상이 아치형으로 형성된 밀착탄지부(26)가 구비된다. 밀착탄지부(26)는 확장캡(24)의 저면이 탄성바(22)가 형성된 중심에서 가장자리부로 갈수록 하향절곡되어 확장캡(24)의 밀착력이 가장자리부로 집중되는 구조를 가진다.In addition, the expansion cap 24 is provided with a close contact portion 26 is formed in an arcuate longitudinal section on the bottom surface in contact with the cupping container (1). The close contact portion 26 has a structure in which the bottom surface of the expansion cap 24 is bent downward from the center where the elastic bar 22 is formed to the edge portion so that the adhesive force of the expansion cap 24 is concentrated to the edge portion.

즉, 밀착탄지부(26)에 의해 확장캡(24)의 저면이 부항용기(1)의 외주면과 전체적으로 면접되지 않고, 가장자리부분이 국부적으로 밀착됨에 따라 사용중 압력누수를 포함하는 작동불량이 방지된다.That is, the bottom surface of the expansion cap 24 is not entirely interviewed with the outer circumferential surface of the cupping container 1 by the close contact portion 26, and the edge portion is locally intimately contacted to prevent a malfunction including pressure leakage during use. .

또, 확장캡(24)의 선단부를 방향에 무관하게 어느 일측에서 가압하면 밀착탄지부(26)가 부항용기(1) 표면으로부터 이격되어 외부공기가 유입되므로 진공압력조절이 간편하게 수행되는 이점이 있다.In addition, if the front end portion of the expansion cap 24 is pressed in any side irrespective of the direction, the close contact portion 26 is separated from the cupping vessel 1 surface, so that the outside air flows, there is an advantage that the vacuum pressure control is easily performed. .
