본 고안은 산소 절단 작업시 별도의 점화기구 없이 팁(화구)에 착화가 가능토록 한 산소절단기에서 압전소자에 구조가 간단한 압착버튼을 눌러 전기를 발생시켰을때 절단기 몸체나 손잡이에는 전기가 흐르지 않게 하기 위하여 외갑체내에 절연체를 삽입하여 점화부 내측의 금속재와 팁(화구)에만 전기가 도통되게 하여 피절단체와 방전되면서 착화 되도록 한 가스절단기의 자동점화 장치에 관한 것이다.The present invention prevents electricity from flowing through the cutter body or handle when oxygen is generated by pressing a simple pressing button on the piezoelectric element in the oxygen cutter that enables ignition on the tip without the need for a separate ignition mechanism. The present invention relates to an automatic ignition device for a gas cutting machine in which an insulator is inserted into an outer shell body so that electricity is conducted only to a metal material and a tip (furnace) inside the ignition unit so as to be ignited while being discharged from the cut body.

종래에는 절단기를 점화시키기 위해 라이타, 성냥, 전기 용접, 불꽂 등 별도의 점화기구를 사용해야 했으므로 휴대의 불편함이 있었고 공지의 압전소자를 이용하여 자동점화 되도록 유도한 절단기에서는 점화버튼 장치의 구조가 복잡하며 팁(화구) 자체에서 방전 스파크가 발생하도록 하므로서 금속재인 절단기 몸체나 손잡이에 전기가 흐르게 되고 또 팁의 방전부위가 변형되어 점화가 잘 되지 않는 등의 문제짐이 있었다.Conventionally, a separate ignition device such as a lighter, a match, an electric welding, and a fire ignition has to be used to ignite the cutting machine, which is inconvenient to carry, and the structure of the ignition button device is complicated in the cutting machine which is induced to auto-ignite using a known piezoelectric element. In addition, there was a problem such that electricity was flowed to the cutter body or the handle, which is a metal material, and the discharge part of the tip was deformed, so that the spark spark occurred at the tip itself.

본 고안은 위와 같은 문제점을 해소하기 위하여 압전소자의 압압버튼 구조를 간단하고도 확실하게 동작할수 있게 구성하고 외갑체에 도전용 금속재를 내장한 절연물을 형성시켜 상기 절연물내에 팁(화구)이 체결삽입되게 함으로서 금속재와 접촉되어 전극이 된 팁과 작업물 사이에서 불꽃 방전을 일으켜 점화 될 수 있게 구성하여 손잡이나 몸체에 전규가 흐르는 것을 방지하고 점화가 확실하게 이루어질 수 있게 하는데에 그 목적이 있는 것이다.The present invention is configured to easily and reliably operate the piezoelectric button structure of the piezoelectric element in order to solve the above problems and to form an insulator incorporating a conductive metal material in the outer shell body to insert the tip (crater) in the insulator The purpose of the present invention is to provide a spark discharge between the tip and the workpiece, which is in contact with the metal material, to ignite the workpiece, thereby preventing the flow of electric charges to the handle or the body and to ensure that the ignition is performed reliably.

이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

기전부(100)는 절단기 몸체의 손잡이(15)부위내측에 공지의 압전소자를 설치하되, 압전소자의 압착부에 경사면(16)이 형성된형의 점화버튼(2)에 스프링(17)을 삽설하여 버튼(2)이 절단기체 손잡이(15)상측에 노출되도록 설치하고 전선관(4)내의 전선(5)이 발화부(200)의 절연물(7)내측에 형성시킨 산소공(12) 및 가스공(14)이 천설된 전도체(6)에 접속되게 하되. 발화부(200)는 외갑체(9)내측에 가스공(14) 및 산소공(12)이 천설되고 개방측에 나사산(18)을 형성시킨 절연물(7)을 장설하고 그 내부 상측에 산소공(12) 및 가스공(14) 이 천설된 금속전도체(6)가 전선관(4)내의 전선(5)과 접촉시켜 부착하여 산소공(12')과 가스공(14')이 천설되고 나사산(18')이 형성된 팁(8)을 절연물(7)내에 설치된 금속도전체(6)와 접촉되게 체결하여 구성된 것을 특징으로하는 산소절단기의 자동점화장치인 것이다.Mechanism unit 100 is a well-known piezoelectric element is installed on the inner side of the handle 15 of the cutter body, the inclined surface 16 is formed in the pressing portion of the piezoelectric element A spring 17 is inserted into the ignition button 2 of the mold so that the button 2 is exposed above the handle 15 of the cutter body, and the wire 5 in the conduit 4 is insulated from the ignition part 200. 7) The oxygen hole 12 and the gas hole 14 formed in the inner side are to be connected to the installed conductor 6, The ignition part 200 installs an insulator 7 in which gas holes 14 and oxygen holes 12 are installed inside the outer shell body 9 and threads 18 are formed on the open side, and oxygen balls are disposed on the upper side thereof. (12) and the metal conductor 6 on which the gas hole 14 is installed is attached in contact with the electric wire 5 in the conduit tube 4 so that the oxygen hole 12 'and the gas hole 14' are laid and threaded ( 18 ') is formed by fastening the tip 8 formed in contact with the metal conductor 6 installed in the insulator 7. The automatic ignition device of the oxygen cutter.

이와 같이 구성된 본 고안의 작용, 효과를 설명하면 다음과 같다.Referring to the operation, effects of the present invention configured as described above are as follows.

팁에 불을 점화시킬 때에는 가스와 산소를 팁(화구)에 분출시킨 다음 발화부(200)를 가공물(금속체)에 접근시키고 점화버튼을 누르면 점화버튼을 하강하게 되어 압전소자도 점화버튼의 경사면(16)에 의하여 압압되어 전기를 발생시키게 되고 이때 발생된 전기는 전선(5)과 금속도전체(6)를 거쳐 팁에 이르게 되어 가공물(금속체)과 불꽃 방전을 이르켜 가스에 점화되는 것이다.When igniting the tip, the gas and oxygen are ejected to the tip (crater), and then the ignition part 200 approaches the workpiece (metal body), and when the ignition button is pressed, the ignition button is lowered. It is pressed by (16) to generate electricity, and the generated electricity reaches the tip through the electric wire 5 and the metal conductor 6, leading to the work (metal body) and the spark discharge to ignite the gas. .

이와 같이 본 고안은 가공물(금속체)에 접근시켜 점화버튼만 누르면 팁과 가공물사이에 불꽃 방전을 일으켜 간단히 점화될 뿐만 아니라 전기도전체를 절단기 본체 및 손잡이와 완전히 절연시켰기 때문에 인체에 감전이 되거나 점화부위가 변형이 일어나는 등의 문제가 전혀 발생치 않는 것이다.As such, the present invention approaches the workpiece (metal), and when the ignition button is pressed, a spark discharge is generated between the tip and the workpiece, and the ignition is simply ignited, and the electric conductor is completely insulated from the cutter body and the handle. There is no problem such as deformation of the site.

이상과 같이 본 고안은 간단한 조작에 의하여 점화가 가능하여 다른 불씨가 전혀 필요없고 또 전기적 절연이 완벽하여 인체에 감전되는 일이 전혀 없는 유용한 고안인 것이다.As described above, the present invention is a useful design that can be ignited by a simple operation so that no other embers are needed and the electrical insulation is perfect so that no electric shock occurs to the human body.
