Abstract
본 고안은 분무통을 등에지고 방제용약제나 물을 분사할수 있게만든 배부식분무기의 피스톤에 관한 것으로 피스톤(1)을 합성수지재로 성형하여 외주면의 둘레에 2-3개의 환형홈(101)을 형성하고 환형홈에 합성고무 또는 고무와 같은 탄성재료로 성형된 피스톤링(102)을 약간 헐겁게 끼워서 된 구성으로 피스톤(1)을 실린더에 삽입하여 작동시킬때 실린더(3)의 내주면과 피스톤(1)을 기밀하게 밀착시키고 피스톤(1)이 실린더(3)와 직접 접촉하지 않음으로 피스톤(1)의 수명이 길고 피스톤(1)의 펌핑작업이 용이하며 피스톤링(102)이 마모되어 기밀성이 떨어지면 피스톤링(102)만을 교체하여 사용함으로 분무기의 유지보수가 편리한 이점이 있는 것이다.The present invention relates to a piston of a dispensing sprayer that has a spray bottle on its back and is capable of injecting a control agent or water. The piston 1 is formed of a synthetic resin to form 2-3 annular grooves 101 around the outer circumferential surface thereof. When the piston (1) is inserted into the cylinder and operated when the piston ring (102) molded in an elastic material such as synthetic rubber or rubber is loosely inserted into the annular groove, the inner peripheral surface of the cylinder (3) and the piston (1) Airtightly adheres to the cylinder and the piston 1 does not come into direct contact with the cylinder 3, so the piston 1 has a long service life, the pumping operation of the piston 1 is easy, and the piston ring 102 is worn and the airtightness decreases. By using only the ring 102 to replace the maintenance of the nebulizer is an advantage.
Description
본 고안은 분무통을 등에지고 방제용약제나 물을 분사할수 있게 만든 배부식분무기의 피스톤에 관한 것으로 보다 구체적으로는 피스톤의 원주면 외주에 피스톤링을 장치하여 실린더의 내벽과 마찰을 줄임과 동시에 기밀을 유지할수있게 한 것이다.The present invention relates to a piston of a dispensing sprayer made by putting a spray bottle on the back and spraying water for controlling chemicals or water. More specifically, the piston ring is installed on the outer circumference of the piston to reduce friction with the inner wall of the cylinder, It will be able to maintain.
배부식분무기는 분무통내에 피스톤과 실린더를 장치하여 피스톤이 실린더 내에서 승강하여 약재를 실린더 내로 흡입하고 피스톤이 하강하면서 발생한 압력에 의해 실린더 로드를 통하여 분무통의 외측으로 분사되게 됨으로 피스톤과 실린더의 기밀한 접촉이 분무기의 성능을 좌우하게 되고 분무기의 성능을 우수하게 하기 위해서는 실린더의 진원도 즉 실린더 단면형상이 정원으로 형성되어야 하며 피스톤이 실린더의 내벽에 기밀하게 밀착하여야 되고 사람이 약제통을 등에지고 피스톤을 작동시켜 분무함으로 최대한의 경량화를 요구하며 피스톤과 실린더 또한 기밀성은 우수하되 마찰력은 감소시켜 피스톤의 펌핑작업이 편리하게 구성하여야 됨으로 상기의 요건을 충족하기 위하여서는 피스톤 및 실린더의 내면가공이 정밀하게 가공되어야 하나 실린더는 무게를 줄이기 위하여 실린더벽의 두게를 얇게 형성함으로 정밀한 가공이 어렵고 가공비용이 많이들게 됨으로 현재 분무기의 실린더는 동합금관을 절단하여 실린더로 사용하고 있어 실린더 단면의 정원유지가 어려워 피스톤의 마모가 극심함으로 실린더와 피스톤의 기밀을 유지하기 위해서는 피스톤의 개선이 요구되고 있다.The spraying device is equipped with a piston and a cylinder in the spray bottle so that the piston is lifted in the cylinder, suctions the medicine into the cylinder, and is sprayed out of the spray bottle through the cylinder rod by the pressure generated as the piston descends. The airtight contact affects the performance of the sprayer, and in order to improve the sprayer's performance, the roundness of the cylinder, that is, the cross-sectional shape of the cylinder, must be formed into a garden, and the piston must be in close contact with the inner wall of the cylinder. It requires maximum weight reduction by spraying the piston, and the piston and cylinder also have excellent airtightness, but the frictional force is reduced to make the pumping work of the piston convenient. Therefore, in order to meet the above requirements, the internal processing of the piston and cylinder is precise. Should be processed As the thickness of the cylinder wall is made thinner to reduce the weight, the precision machining is difficult and the processing cost becomes high. Currently, the cylinder of the sprayer is used as a cylinder by cutting the copper alloy pipe. In order to maintain the tightness of the cylinder and the piston to the extreme, improvement of the piston is required.
종래의 피스톤은 피혁원판을 실린더로드의 끝에 부착하여 사용하는 것이 있으나 이는 피혁원판이 수분을 흡수하게 되면 부풀어 팽창하게되어 피스톤의 펌핑작업이 어렵게 되는 결점이 이었고 이를 개선하여 합성수지 또는 합성고무재로 피스톤을 성형하여서 된 피스톤이 있으나 합성수지재로 성형한 것은 연질재료를 사용하여 성형하여도 실린더의 내벽과 밀착성이 떨어지는 결점이 있고 합성고무재로 성형한 것은 약재의 독성과 실린더내의 압력에 의해 쉽게 변형됨으로 이를 방지하기 위하여 피스톤내에 원판형 철편을 넣어서 성형함으로 피스톤의 제조공정이 복잡하고 분무기의 무게 및 원가가 상승하며 피스톤의 본체가 실린더의 내주벽과 밀착하게 되어 마찰저항이 크고 피스톤의 승하강 작동에 의해 외주면이 마모되면 실린더 전체를 교체하여야 함으로 분무기의 유지관리 또한 어려운 결점이 있었다.Conventional pistons are used by attaching leather discs to the ends of cylinder rods, but this is a disadvantage that the leather discs swell and expand when absorbing moisture, making it difficult to pump the pistons. Although there is a piston formed by molding, the molded part of synthetic resin material has the disadvantage of inferior adhesion with the inner wall of the cylinder even when molded using soft material, and the molded part of synthetic rubber material is easily deformed by the toxicity of chemicals and the pressure in the cylinder. In order to prevent this, by inserting disk-shaped iron pieces into the piston, the manufacturing process of the piston is complicated, the weight and cost of the sprayer are increased, and the main body of the piston is in close contact with the inner circumferential wall of the cylinder. If the outer circumference wears out, replace the entire cylinder. The maintenance of the nebulizer was also a difficult drawback.
본 고안은 상기와 같은 종래의 결점을 개선하여 피스톤의 외주에 피스톤링을 끼워서 피스톤링이 실린더의 내주면에 밀착되게 하여 피스톤과 실린더의 마찰력을 줄이고 기밀성을 좋게한 것으로 이를 첩부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention improves the conventional drawbacks as described above to fit the piston ring to the outer circumference of the piston so that the piston ring is in close contact with the inner peripheral surface of the cylinder to reduce the friction between the piston and the cylinder and improve airtightness in detail based on the attached drawings. The explanation is as follows.

도 1은 본고안의 구성이 예시되어 있다.1 illustrates a configuration of the present invention.
즉 본고안의 피스톤(1)을 합성수지재로 성형하여 외주면의 둘레에 2-3개의 환형홈(101)을 형성하고 환형홈내에 합성고무 또는 고무재와 같은 탄성재료로 성형된 피스톤링(102)을 약간 헐겁게 끼워서된 구조이다.That is, the piston 1 of the present invention is molded with synthetic resin to form 2-3 annular grooves 101 around the outer circumference and the piston ring 102 formed of an elastic material such as synthetic rubber or rubber material in the annular groove. It is a slightly loosened structure.
이와 같이된 본 고안은 피스톤(1)을 피스톤로드(103)에 밀착시켜서 볼트(2)로 결합하여 피스톤로드(013)을 강제 승·하강 작동시켜 분무통(4)내의 약제를 펌핑하여 피스톤로드(103)를 통해 분사관으로 분출하는 구성으로 피스톤(1)이 승강하면 분무통(4)내의 약제가 실린더(3)의 내측으로 흡입되고 피스톤(1)이 하강하면 실린더내(3)의 약제가 압력을 받게되어 피스톤로드(103)를 통해 분무관으로 공급되어 분사되게 되는 것이다.According to the present invention as described above, the piston 1 is brought into close contact with the piston rod 103, and the piston rod 013 is coupled to the piston rod 013 to force the piston rod 013 to operate. When the piston (1) is raised and lowered in a configuration that ejects to the injection pipe through the 103, the drug in the spray container (4) is sucked into the cylinder (3), and when the piston (1) is lowered, the drug in the cylinder (3) The pressure is to be supplied to the spray pipe is sprayed through the piston rod (103).
이와같이된 본 고안은 피스톤(1)에 피스톤링(102)이 장치되어 실린더(3)의 내주면과 기밀하게 밀착되고 접촉면이 적게 되어 피스톤(1)의 펌핑작업이 쉽게되는 이점이 있다.The present invention as described above has the advantage that the piston ring 102 is installed in the piston 1 to be in close contact with the inner circumferential surface of the cylinder 3 and the contact surface is small, so that the pumping operation of the piston 1 is easy.
또한 피스톤(1)이 실린더(3)와 접촉하지 않음으로 피스톤(1)의 수명이 영구적으로 되고 피스톤링(102)이 마모되어 기밀성이 떨어지면 피스톤링(102)만을 교체하여 사용함으로 분무기의 유지보수가 편리한 이점이 있는 것이다.In addition, when the piston 1 does not come into contact with the cylinder 3, the life of the piston 1 becomes permanent, and the piston ring 102 is worn out. There is a convenient advantage.
