Description

배출펌프{PUMP}Discharge Pump {PUMP}

본 고안은 펌핑 작동을 하여 용기에 수용된 화장품을 일정량씩 외부로 배출 사용할 수 있도록 하는 배출펌프에 관한 것으로, 특히 펌핑 작동에 의해 내용물이 배출할 때 실린더 내부에서 승하강하는 밀폐피스톤과 접촉하는 실린더튜브와의 접촉면적을 최소화 시켜 밀폐피스톤이 부드럽게 작용할 수 있도록 한 배출펌프에 관한 것이다.The present invention relates to a discharge pump for pumping operation to discharge the cosmetics contained in the container by a certain amount to the outside, in particular, the cylinder tube in contact with the sealing piston rising and falling inside the cylinder when the contents are discharged by the pumping operation The present invention relates to an exhaust pump that minimizes the contact area with and allows the closed piston to operate smoothly.

일반적으로 용기 내부에 담겨져 있는 화장품, 샴푸, 세제류 등의 내용물을 적당량씩 배출 사용하기 위한 수단의 하나로 용기에 배출펌프를 장착 사용하게 된다.In general, one of the means for discharging and using the appropriate amount of the contents, such as cosmetics, shampoo, detergents contained in the inside of the container is equipped with a discharge pump to use.

상기와 같이 용기에 장착되어 내용물을 소량씩 배출 사용하는 기존의 배출펌프는 다양하게 착안 되어있으나, 일반적인 배출펌프의 구조는 첨부도면 도 1에 도시된 바와 같이 내용물유입공(111)을 개폐하는 개폐볼(112)과, 작동피스톤(113)이 스프링(114)의 탄성력을 받도록 설치되어 있고, 상기 작동피스톤(113)으로 내용물저장실(115) 내에 압력을 가해 내용물저장실(115) 수용된 내용물을 누름버튼(120)을 통해 배출되도록 이루 어진 실린더(100)가 펌프본체(130)에 설치되어 있는 것이다.Existing discharge pump is installed in a container as described above using a small amount of the contents discharged in various ways, but the structure of a general discharge pump opening and closing the opening and closing the contents inlet hole 111 as shown in Figure 1 attached The ball 112 and the operating piston 113 is installed to receive the elastic force of the spring 114, the pressure is applied to the contents storage chamber 115 by the operation piston 113, the contents stored in the contents storage chamber 115 push button Cylinder 100 is made to be discharged through the 120 is installed in the pump body (130).

상기 작동피스톤(113) 외주연부에는 상, 하부테두리(116a)(116b)를 갖는 밀폐피스톤(116)이 더 설치되어 있고, 상기 작동피스톤(113)과 누름버튼(120) 사이에는 연결이송관(121)이 설치되어 있는 것이다.An outer circumferential portion of the working piston 113 is further provided with a sealed piston 116 having upper and lower edges 116a and 116b, and a connection transfer pipe (120) between the operating piston 113 and the push button 120. 121) is installed.

또한, 상기 펌프본체(130)에 마련된 실린더하우징(131)에는 실린더튜브(117)가 장착되고 상기 실린더튜브(117)의 내주연부에는 상기 밀폐피스톤(116)과 접촉되어 있다. In addition, the cylinder housing 131 provided in the pump body 130 is mounted with a cylinder tube 117 and the inner peripheral portion of the cylinder tube 117 is in contact with the sealing piston 116.

상기한 구성을 갖는 종래의 내용물 배출펌프의 작용상태를 알아볼 것 같으면 첨부도면 도2에 도시된 바와 같이 누름버튼(120)을 누르면 연결이송관(121)이 하강함과 동시에 작동피스톤(113)이 하강하면서 밀폐피스톤(116)과 작동피스톤(113)의 사이에 공극이 먼저 발생하게 된다. 따라서 이 공극으로 내용물저장실(115)에 수용되어 있던 내용물이 배출되어지게 된다.If the operation state of the conventional contents discharge pump having the above configuration is to be seen, as shown in the accompanying drawings, press the push button 120, as shown in Figure 2, the connection pipe 121 is lowered and at the same time the operation piston 113 While descending, a gap is first generated between the sealing piston 116 and the working piston 113. Therefore, the contents contained in the contents storage chamber 115 are discharged to the voids.

이때 개폐볼(112)은 압축되는 스프링(114)에 의해 내용물유입공(111)에 밀착되어져 내용물 유입이 차단하게 된다.At this time, the opening and closing ball 112 is in close contact with the contents inlet hole 111 by the spring 114 is compressed to block the inflow of the contents.

상기에서와 같이 누름버튼(120)을 눌러 내용물을 배출한 다음 누름버튼(120)에 가해졌던 외력을 해제하면, 스프링(114)에 압축된 반발력에 의해 작동피스톤(113)과 밀폐피스톤(116)이 함께 상승하게 된다.Pressing the push button 120 to discharge the contents as described above, and then release the external force applied to the push button 120, the operating piston 113 and the closed piston 116 by the repulsive force compressed by the spring 114 This rises together.

그러나 상기와 같이 승하강하는 밀폐피스톤(116)이 실린더튜브(117) 내부에서 작용할 때 첨부도면 도 3에 도시된 바와 같이 밀폐피스톤(116) 상, 하부테두리(116a)(116b)와 실린더튜브(117) 내주연부의 접촉되는 면적이 크기 때문에 고무재질인 밀폐피스톤(124)이 변형되는 현상이 자주 발생하게 되며, 이는 진공을 유지하여야 하는 내용물 저장실(115)의 기능이 상실되는 문제점이 발생하게 된다.However, as shown in FIG. 3, when the sealing piston 116 ascending and descending acts inside the cylinder tube 117, the lower edges 116a and 116b and the cylinder tube ( 117) Since the contact area of the inner circumference is large, a phenomenon in which the sealing piston 124, which is a rubber material, is frequently caused, causes a problem that the function of the contents storage chamber 115 to maintain the vacuum is lost. .

상기와 같이 내용물 저장실(115)에서 진공에 대한 문제점이 발생하면 내용물이 적정량이 배출되어야 하는데 그 이하로 배출되는 경우가 발생하게 된다.As described above, when a problem with vacuum occurs in the contents storage chamber 115, the contents should be discharged to an appropriate amount, but less than that.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 그 목적으로는 승하강하는 밀폐피스톤과 접촉하는 실린더튜브의 접촉면적을 최소화 시켜 밀폐피스톤이 매끄럽게 작용할 수 있도록 하여 내용물 저장실에 진공을 유지하도록 하는 것을 제공함에 있다 하겠다.The present invention has been devised to solve the above problems, and the purpose of this is to minimize the contact area of the cylinder tube in contact with the rising and falling sealed pistons so that the sealed pistons can operate smoothly to maintain the vacuum in the contents storage compartment. It is in providing what it does.

상기 목적을 달성하기 위한 본 고안은 누름버튼(20)을 눌러 실린더(30)를 통해 내용물을 적당량씩 배출 사용할 수 있도록 하는 펌프본체(40)를 포함하는 배출펌프(10)에 있어서, 상기 실린더(30)에 마련된 실린더튜브(31) 내주연부에는 밀폐피스톤(32)이 승하강할 때 밀폐피스톤(32) 변형을 방지하는 피스톤변형방지수단(50)이 마련된 것으로 달성된다.The present invention for achieving the above object in the discharge pump (10) comprising a pump body (40) to be used to discharge the contents by a suitable amount by pressing the push button (20), the cylinder ( The inner peripheral portion of the cylinder tube 31 provided at 30 is provided with a piston deformation preventing means 50 which prevents deformation of the sealing piston 32 when the sealing piston 32 is raised and lowered.

본 고안은 배출펌프의 펌핑 작동에 의해 내용물이 배출할 때 실린더 내부에서 승하강하는 밀폐피스톤과 접촉하는 실린더튜브의 접촉면적을 최소화 시켜 밀폐피스톤이 변형됨이 없이 부드럽게 작용함으로서 내용물 저장실의 진공효과가 가일층 높일 수 있도록 하는 효과가 있다.The present invention minimizes the contact area of the cylinder tube in contact with the sealed piston which is raised and lowered inside the cylinder when the contents are discharged by the pumping operation of the discharge pump, thereby smoothly operating without deforming the sealed piston, thereby improving the vacuum effect of the storage compartment. It is effective to further increase.

이하에서는 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings as follows.

먼저, 첨부도면 도 4에 도시된 바와 같이 누름버튼(20)을 눌러 실린더(30)를 통해 내용물을 적당량씩 배출 사용할 수 있도록 하는 펌프본체(40)에는 상기 실린더(30)에 마련된 실린더튜브(31)가 장착될 수 있도록 하는 실린더하우징(41)이 마련되어 있다.First, as shown in FIG. 4, a cylinder tube 31 provided in the cylinder 30 is provided in the pump body 40 so that the contents can be discharged by an appropriate amount through the cylinder 30 by pressing the push button 20. Is provided with a cylinder housing 41 for mounting.

상기 실린더튜브(31) 내주연부에는 내용물저장실(34)있는 내용물을 밀폐시키는 밀폐피스톤(32) 상,하부테두리(32a)(32b)와 접촉되며, 상기 밀폐피스톤(32) 상측단부에는 상기 누름버튼(20)과 결합된 연결이송관(21)이 배치되어 있으며, 밀폐피스톤(32)의 하측단부에는 작동피스톤(35)이 마련되어 있다.The inner circumferential portion of the cylinder tube 31 is in contact with the upper and lower borders 32a and 32b of the sealing piston 32 for sealing the contents of the contents storage chamber 34, and the push button at the upper end of the sealing piston 32. A connection transfer pipe 21 coupled to the 20 is disposed, and an operating piston 35 is provided at the lower end of the sealed piston 32.

상기 실린더튜브(31) 내주연부에는 상기 밀폐피스톤(32)의 승 하강할 때 밀폐피스톤(32) 변형을 방지하는 피스톤변형방지수단(50)이 마련되어 있다.An inner circumferential portion of the cylinder tube 31 is provided with a piston deformation preventing means 50 for preventing deformation of the sealing piston 32 when the sealing piston 32 is raised and lowered.

그리고, 상기 피스톤변형방지수단(50)에는 격자형상의 널링(51)이 형성될 수 있다.In addition, the piston deformation preventing means 50 may be formed with a grid-like knurling 51.

상기와 같이 구성된 본 고안의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

첨부도면 도 5에 도시된 바와 같이 누름버튼(20)을 누르면 연결이송관(21)이 하강함과 동시에 작동피스톤(35)이 하강하게 된다. 이때 밀폐피스톤(32)은 탄성재질로 되어 있어 잠시 실린더튜브(31) 내주연부와 밀착된 상태로 정지하고 있다가 다시 하측으로 짧은 거리만큼 이동 정지하게 된다.As shown in FIG. 5, when the push button 20 is pressed, the connection transport tube 21 descends and the operation piston 35 descends. At this time, the sealing piston 32 is made of an elastic material and stops in a state of being in close contact with the inner circumference of the cylinder tube 31 for a while, and then stops moving downward by a short distance.

따라서 작동피스톤(35)과 밀폐피스톤(32)이 이격되는 공간(S)이 형성되고 이 공간(S)으로 내용물저장실(34)에 있던 압축된 내용물이 배출되는 것이다.Therefore, the space (S) in which the working piston (35) and the sealing piston (32) is formed is formed, and the compressed content in the contents storage chamber (34) is discharged into this space (S).

이때에도 종래와 마찬가지로 개폐볼(112)은 압축되는 스프링(114)에 의해 내용물유입공(111)에 밀착되어져 내용물 유입이 차단하게 된다. In this case, as in the prior art, the opening and closing ball 112 is in close contact with the contents inlet hole 111 by the spring 114 is compressed to block the inflow of the contents.

상기에서와 같이 누름버튼(20)을 눌러 내용물을 배출한 다음 누름버튼(20)에 가해졌던 외력을 해제하면, 스프링(114)에 압축된 반발력에 의해 작동피스톤(35)과 밀폐피스톤(32)이 함께 상승하게 된다.Pressing the push button 20 to discharge the contents as described above, and then release the external force applied to the push button 20, the operating piston 35 and the closed piston 32 by the repulsive force compressed by the spring 114 This rises together.

한편 상기와 같이 첨부도면 도 6a 내지 6b에 도시된 바와 같이 밀폐피스톤(32)이 승하강할 때 상, 하부테두리(32a)(32b)는 실린더튜브(31)에 마련된 피스톤변형방지수단(50)의 널링(51) 에 의해 접촉면적이 종래에 비해 줄어들므로 변형됨이 없이 부드럽게 작용하게 된다.Meanwhile, as shown in FIGS. 6A to 6B, the upper and lower edges 32a and 32b of the piston deformation preventing means 50 provided in the cylinder tube 31 are raised and lowered as shown in FIGS. 6A to 6B. By the knurling 51, the contact area is reduced compared to the prior art, thereby smoothly working without deformation.

전술한 실시예는 본 고안의 바람직한 실시예를 설명한 것에 불과하므로, 본 고안의 적용 범위는 이와 같은 것에 한정되지 않으며, 동일 사상의 범주내에서 적절한 변경이 가능하다. 따라서, 본 고안의 실시예에 나타난 각 구성 요소의 형상 및 구조는 변형하여 실시할 수 있으므로, 이러한 형상 및 구조의 변형은 첨부된 본 고안의 특허청구범위에 속함은 당연한 것이다.Since the above-described embodiment is merely a description of a preferred embodiment of the present invention, the scope of application of the present invention is not limited to such, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
