Description

Air pump

본 고안은 에어펌프에 관한 것으로서, 더 상세하게는 수축/확장되어 공기를흡입/배기시키는 러버펌프에 흡기/배기밸브를 일체로 형성함으로써 조립을 간편하게 하고 하나의 동력원으로부터 구동되는 러버펌프를 복수개 구비함으로써 펌프효율이 향상되도록 개선된 에어펌프에 관한 것이다.The present invention relates to an air pump, and more particularly, by integrating the intake / exhaust valve into a rubber pump that contracts / expands air intake / exhaust, thereby simplifying assembly and providing a plurality of rubber pumps driven from one power source. The present invention relates to an improved air pump to improve pump efficiency.

일반적인 에어펌프가 도1에 도시되어 있다. 이는 모터(10)가 상부플레이트(20)에 결합되고, 모터(10)의 편심회전축(11)에는 러버펌프(30)가 승하강 가능하게 결합되며, 러버펌프(30)의 하부에는 하부플레이트(50)가 상부플레이트(20)와 기밀을 유지하도록 결합되고, 하부플레이트(50)와 러버펌프(30) 사이에 배출구(42)와 흡입구(41)가 관통되어 형성된 중간플레이트(40)가 설치되고, 중간플레이트(40)의 배출구(42)와 흡입구(41)에는 러버펌프(30)의 펌핑에 의해 배출구(42)와 흡입구(41)를 개폐하는 고무밸브(60)가 설치된 구조로 되어 있다.A typical air pump is shown in FIG. This is the motor 10 is coupled to the upper plate 20, the rubber pump 30 is coupled to the eccentric rotation shaft 11 of the motor 10 to be able to move up and down, the lower plate (below the rubber pump 30) 50 is coupled to maintain the airtight with the upper plate 20, the intermediate plate 40 is formed between the lower plate 50 and the rubber pump 30 through the discharge port 42 and the suction port 41 is installed, The outlet 42 and the inlet 41 of the intermediate plate 40 have a structure in which a rubber valve 60 is installed to open and close the outlet 42 and the inlet 41 by pumping the rubber pump 30.

참조번호 111a,112a 및 121a,122a 제1,2러버부재(110)(120)로부터 연장된 패킹체로서 메인프레임(150)과 상하부플레이트(130)(140) 사이의 공기 흡배기 통로 주변을 밀폐시키는 패킹역활을 한다.Reference numerals 111a, 112a and 121a, 122a are packings extending from the first and second rubber members 110 and 120 to seal the air intake and exhaust passages between the main frame 150 and the upper and lower plates 130 and 140. It acts as a packing.

이와 같이 구성된 본 고안 에어펌프는 다음과 같이 작동된다.Invented air pump configured as described above is operated as follows.

모터(100)가 구동되면 편심축(101)에 의해 제1러버부재(110)와 제2러버부재(120)는 순차적으로 수축 및 확장을 하게 되면서 새로운 공기가 유입되어 압축되고 압축된 공기는 토출포트(155)(156)를 통해서 토출되게 된다.When the motor 100 is driven, the first rubber member 110 and the second rubber member 120 are sequentially contracted and expanded by the eccentric shaft 101 while new air is introduced and compressed and the compressed air is discharged. Discharged through the ports 155 and 156.

즉, 도4a를 참조하면, 제1러버부재(110)가 편심축(101)에 의해 수축되게 되면, 상부플레이트(130)와 제1러버부재(110)에 의해 형성된 공간에 유입된 공기들이 상부배기공(153)을 통해 토출포트(155)로 토출된다. 이때 제1배기밸브(112)는 제1러버부재(110)의 수축으로 인한 압축공기에 의해 휘어지면서 배기홈(132) 및 상부배기공(153)의 통로를 연통시킨다. 동시에 상부흡입공(151)은 배기되는 공기로 인해 제1흡기밸브(111)는 상부흡입공(151)에 흡착되어 외부공기의 유입을 방지시킨다.That is, referring to FIG. 4A, when the first rubber member 110 is contracted by the eccentric shaft 101, the air introduced into the space formed by the upper plate 130 and the first rubber member 110 is upper. The discharge port 155 is discharged through the exhaust hole 153. At this time, the first exhaust valve 112 is bent by the compressed air due to the contraction of the first rubber member 110 to communicate the passage of the exhaust groove 132 and the upper exhaust hole 153. At the same time, the upper suction hole 151 is adsorbed by the upper suction hole 111 due to the exhausted air, thereby preventing the inflow of external air.

한편, 제1러버부재(110)의 수축으로 인한 공기의 토출과 동시에, 제2러버부재(120)는 확장되어 하부플레이트(140)와 제2러버부재(120)에 의해 형성된 공간에 새로운 공기들이 유입된다. 즉, 제2러버부재(120)가 확장되게 되면, 그 흡입력으로제2흡기밸브(121)가 개방되면서 하부흡입공(152) 및 흡기홈(141)을 통해 외부공기가 유입되고, 반대로 제2배기밸브(122)는 제2러버부재(120)의 흡입력에 의해 하부배기공(154)을 차단하게 된다.Meanwhile, at the same time as the air is discharged due to the contraction of the first rubber member 110, the second rubber member 120 is expanded to introduce new air into the space formed by the lower plate 140 and the second rubber member 120. Inflow. That is, when the second rubber member 120 is expanded, the second air intake valve 121 is opened by the suction force, and the outside air flows through the lower suction hole 152 and the intake groove 141, and conversely, the second rubber member 120 is opened. The exhaust valve 122 blocks the lower exhaust hole 154 by the suction force of the second rubber member 120.

즉, 도4a는 제1러버부재(110)의 수축으로 공기가 배기되고 제2러버부재(120)는 확장되어 외부공기가 유입되는 작동을 하게 된다.That is, FIG. 4A shows that the air is exhausted by the contraction of the first rubber member 110 and the second rubber member 120 is expanded to operate the external air.

한편, 도4b는 도4a와 반대동작으로서, 제1러버부재(110)의 확장으로 외부공기가 유입되고 제2러버부재(120)는 수축되어 유입된 공기가 배기되는 작동을 하게 된다. 이에 대한 작동은 상술한 도4a의 동작과 유사하므로 상세한 설명은 생략한다.On the other hand, Figure 4b is the reverse operation of Figure 4a, the expansion of the first rubber member 110, the outside air flows in and the second rubber member 120 is contracted to perform the operation to exhaust the introduced air. Operation thereof is similar to that of FIG. 4A described above, and thus a detailed description thereof will be omitted.

상기와 같이 토출포트(155)(156)를 통해 토출된 공기는 연결된 고무호스(160)를 통해, 예컨대 혈압측정기와 같은 에어튜브에 공급된다.The air discharged through the discharge ports 155 and 156 as described above is supplied to an air tube such as a blood pressure meter through the connected rubber hose 160.

이와 같은 본 고안은 제1,2러버부재(110)(120)가 하나의 동력원으로부터 수축/확장을 순차적으로 함으로써 외부공기를 연속적으로 공급받아 압축배기시킴으로써 펌프효율이 향상된다.The present invention as described above, the pump efficiency is improved by the first and second rubber members 110, 120 are continuously supplied with compressed air by sequentially contracting / expansion from one power source.

또한, 제1,2러버부재(110)(120)에 흡기밸브와 배기밸브가 일체로 형성됨으로써, 관리부품수를 절감하여 부품관리가 수월하고, 또한 조립을 간편하게 한다.In addition, since the intake valve and the exhaust valve are integrally formed in the first and second rubber members 110 and 120, the number of parts to be managed is reduced, so that parts management is easy and assembly is simplified.
