본 고안은 에어건(Air Gun)에 관한 것으로서, 더욱 상세하게는 에어건에 사용하여 압축공기를 분사할수 있고, 분진 및 옴등을 흡입하여 회수할수 있도록 한 것이다.The present invention relates to an air gun, and more specifically, it can be used for air guns to inject compressed air, and to recover by inhaling dust and scabs.
종래의 압축공기를 분사하는 에어건은 제1도에 나타낸 바와같이, 에어건의 본체(1a)전방과 손잡이(12)하방을 관통하여 통공(16)이 형성되고, 상기 손잡이(12)의 일측선단에 체결너트(7a)로서 고정된 버튼(13)이 설치되며, 상기 버튼(13)후방의 손잡이(12)내에는 탄성을 부여하는 스프링(14)이 삽입된 유로개폐밸브(15)가 설치되어 상기 통공(16)을 폐쇄시키고, 상기 손잡이(12)의 하단에는 에어호스(17)를 연결하기 위한 커플링(18)이 설치되어 구성된다.As shown in FIG. 1, a conventional air gun for injecting compressed air passes through the front of the main body 1a of the air gun and the lower part of the handle 12 to form a through hole 16, and at one end of the handle 12. A button 13 fixed as a fastening nut 7a is installed, and a flow path opening / closing valve 15 into which a spring 14 for imparting elasticity is inserted is installed in the handle 12 behind the button 13. The through hole 16 is closed and a coupling 18 for connecting the air hose 17 is installed at the lower end of the handle 12.
따라서, 에어건으로 압축공기를 분사시키고자 할때에는, 에어건의 손잡이 (12)하단에 설치된 커플링(18)에 에어호스(17)를 연결하여 청소하고자하는 곳에 에어건의 토출구를 향하게 한후에 손잡이(12)에 설치된 버튼(13)을 누르면, 상기 손잡이(12)내의 스프링(14)이 압축되어 유로개폐밸브(15)가 통공(16)을 열어주므로 약 5∼7kg/cm2의 압축공기가 에어건의 통공(16)을 통해서 토출구로 분사하게 된다.Therefore, when spraying compressed air with the air gun, the air hose 17 is connected to the coupling 18 installed at the bottom of the air gun knob 12 so that the air outlet 17 of the air gun is directed to the outlet of the air gun, and then the handle 12 is opened. When the button 13 installed on the button 13 is pressed, the spring 14 in the handle 12 is compressed and the flow opening / closing valve 15 opens the opening 16 so that about 5 to 7 kg / cm 2 of compressed air is supplied to the air gun. Through 16, it is injected into the discharge port.
그러나, 이와같은 종래의 에어건은 단순히 압축공기의 토출로 인한 국부적인 청소로서, 오물및 분진등을 흡입할수 없을뿐만 아니라, 토출력이 약하므로 기계등에 누저고딘 이물질등을 제거할수 없는 등의 문제점이 있었다.However, such a conventional air gun is simply a local cleaning due to the discharge of compressed air, and not only can not suck in dirt and dust, but also has a weak earth output, so it is not possible to remove foreign substances that have leaked into the machine. there was.

A recovery container 10 made of a nonwoven fabric is fixed as the clamp 11.
또한, 본체(1)하방의 손잡이(12)일측선단에 체결너트(7a)로서 고정된 버튼 (13)이 설치되고, 상기 버튼(13) 후방이 손잡이(12)내에는 탄성력있는 스프링 (14)이 삽입된 유로개폐밸브(15)가 설치되어 상기 본체(1)전방과 손잡이(12)하방을 관통하여 형성된 통공(16)을 폐쇄시키며, 상기 손잡이(12)의 하단에는 에어호스 (17)를 연결하는 커플링(18)이 설치되어 구성된다.In addition, a button 13 fixed as a fastening nut 7a is installed at one end of the handle 12 below the main body 1, and the rear of the button 13 has an elastic spring 14 in the handle 12. The inserted flow path opening and closing valve 15 is installed to close the through hole 16 formed through the front of the main body 1 and the lower portion of the handle 12, and an air hose 17 is disposed at the lower end of the handle 12. The coupling 18 which connects is provided and comprised.
이와같이 구성된 본 고안은 제2도 및 제3도(a)에 나타낸 바와같이, 에어건의 본체(1)내에 이젝터(2)가 설치되고, 손잡이(12)하단의 커플링(18)에 에어호스(17)를 연결시킨후 상기 본체(1)의 선단에는 연결관(9)이 고정되며, 상기 본체(1)후단에는 핀파이프(8)끝단에 클램프(11)로서 필터역할을 하는 부직포로된 회수용기(10)가 고정된 상태에서 에어건을 사용하여 분진 및 오물등을 흡입시키고자 할때에는 에어건의 손잡이(12)에 설치된 버튼(13)을 당기면, 상기 버튼(13)후방의 손잡이 (12)내의 유로개폐밸브(15)에 삽입된 스프링(14)이 압축된다.According to the present invention configured as described above, as shown in FIGS. 2 and 3 (a), the ejector 2 is installed in the main body 1 of the air gun, and the air hose (3) is provided at the coupling 18 below the handle 12. 17) is connected, the connecting pipe (9) is fixed to the front end of the main body 1, the number of non-woven fabric to act as a filter as a clamp 11 at the end of the pin pipe (8) at the rear end of the main body (1) When the container 10 is fixed and the dust and dirt are to be sucked in by using the air gun, the button 13 installed on the handle 12 of the air gun is pulled, and the handle 12 in the rear of the button 13 is pulled out. The spring 14 inserted into the flow path opening and closing valve 15 is compressed.
이와동시에, 본체(1)전방과 손잡이(12)하방을 관통하여 형성된 통공(16)을 막고있는 유로개폐밸브(15)가 열리면서 압축공기가 상기 통공(16)을 통해 공급되어 이젝터(2)의 요입홈(4)일측 끝단에 소정 간격으로 상기 이젝터(2)를 관통하여 경사지게 형성된 복수개의 유로공(5)으로 압축공기가 제3도(a)와 같이 후방으로 빠져나오게 된다.At the same time, the passage opening / closing valve 15 blocking the opening 16 formed through the front of the main body 1 and the handle 12 is opened, and compressed air is supplied through the opening 16 so that the ejector 2 of the ejector 2 is opened. Compressed air is discharged to the rear side as shown in FIG. 3 (a) to a plurality of flow path holes 5 formed inclined through the ejector 2 at predetermined intervals at one end of the concave indentation groove 4.
이때, 통공(16)을 거쳐 이젝터(2)의 요입홈(4)으로 들어오는 압축공기는 상기 요입홈(4)의 일측끝단에 경사지게 형성된 복수개의 유로공(5)으로 들어오면서 유속이 급속히 빨라지게 된다.At this time, the compressed air entering the recessed groove 4 of the ejector 2 through the through hole 16 is introduced into the plurality of flow paths 5 inclined at one end of the recessed groove 4 so that the flow velocity is rapidly increased. do.
즉, 이젝터(2)의 요입홈(4)과 유로공(5)의 급격한 직경의 차이로 인한 단면적과 속도는 반비례함에 따라 유속이 급격하게 증가하게 된다.That is, the cross-sectional area and the speed due to the difference in the sharp diameters of the recessed grooves 4 and the flow paths 5 of the ejector 2 are inversely proportional, and the flow rate is rapidly increased.
반면에, 유속과 압력은 반비례함에 따라 유속의 급격한 증가에 따른 압력저하 현상이 발생하게 되어 외부의 분진 및 오물등이 연결관(9)으로 들어와서 에어건 본체(1)후장의 핀파이프(8)끝단에 고정된 회수용기(10)로 포집되고, 토출된 공기는 상기 회수용기(10)에서 필터링되어 대기로 방출 시킨다.On the other hand, the flow rate and pressure are inversely proportional to the pressure drop due to the rapid increase in the flow rate, so that dust and dirt from the outside enter the connecting pipe 9 and the fin pipe 8 of the rear of the air gun body 1 Collected by the recovery vessel 10 fixed at the end, the discharged air is filtered in the recovery vessel 10 to be discharged to the atmosphere.
또한, 에어건을 사용하여 압축공기를 분사시키고자 할때에는 제3도의(a)와 같이 에어건의 본체(1)내에 이젝터(2)가 고정된 상태에서 이젝터(2)를 분해시킨후, 제3도(b)에 나타낸 바와같이 상기 이젝터(2)를 에어건의 본체(1)내에 반대방향으로 고정시킨다.In addition, when injecting compressed air using an air gun, the ejector 2 is disassembled while the ejector 2 is fixed in the main body 1 of the air gun as shown in FIG. As shown in (b), the ejector 2 is fixed in the main body 1 of the air gun in the opposite direction.
그후, 에어건의 손잡이(12)하단의 커블링(18)에 에어호스(17)를 연결시킨후, 에어건의 손잡이(12)에 설치된 버튼(13)을 당기면, 상기 버튼(13)후방의 손잡이 (12)내의 유로개폐밸브(15)가 열리면서 압축공기가 통공(16)을 통해 공급되어 이젝터(2)의 요입홈(4)일측끝단에 소정간격으로 이젝터(2)를 관통하여 경사지게 형성된 복수개의 유로공(5)으로 제3도의(b)와 같이 전방으로 빠져나오게 되어 압축공기를 분사시키게 된다.Thereafter, after connecting the air hose 17 to the coupling 18 at the bottom of the handle 12 of the air gun, and pulling the button 13 installed on the handle 12 of the air gun, the handle behind the button 13 ( 12) A plurality of flow paths are formed to be inclined to pass through the ejector 2 at predetermined intervals at one end of the inlet groove 4 of the ejector 2 by supplying the compressed air through the through hole 16 while the flow path open / close valve 15 is opened. The ball 5 is discharged forward as shown in (b) of FIG. 3 to inject compressed air.
이때, 압축공기가 요입홈(4)의 일측끝단에 경사지게 형성된 복수개의 좁은 유로공(5)으로 들어올때 급속한 유속증가로 인한 토출력이 배가되어 압축공기를 효율적으로 투출시키게 된다.At this time, when the compressed air enters the plurality of narrow passage holes 5 which are inclined at one end of the concave groove 4, the output power due to the rapid flow rate is doubled to efficiently discharge the compressed air.
이상에서와 같이, 본 고안은 에어건의 본체(1)내에 흡입 및 분사시에 따라 이젝터(2)를 설치하고 분진 및 오물등의 흡입시 본체(1)의 선단과 후방의 핀파이프 (8)끝단에 각각 연결관(9)과 필터역할을 하는 부직포로된 회수용기(10)를 설치하므로써, 에어건을 사용하여 압축공기의 분사뿐만 아니라 분진 및 오물등을 흡입하여 회수할수 있고 토출력 및 청소효율을 향상시킬수 있으므로 인한 에어건의 효율성 및 신뢰성을 대폭향상시킨 매우 유용한 고안이다.As described above, the present invention installs the ejector 2 in the main body 1 of the air gun at the time of suction and injection, and the tip of the main pipe 1 at the end of the main pipe 1 and the end of the pin pipe 8 at the time of suction of dust and dirt. By installing each of the connecting pipes 9 and the recovery container 10 made of a nonwoven fabric acting as a filter, the air gun can be used to suck and collect not only the compressed air but also to collect dust and dirt, and to improve the output and cleaning efficiency. It is a very useful design that can greatly improve the efficiency and reliability of the air gun.
