Description

Auto ignition oxygen-saving torch}

      BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic oxy-storage torch as a gas torch used for cutting or brazing a workpiece of metal material, applying heat, or welding.

      In more detail, when the spark roller provided in the torch head of the present invention is pushed or pulled by contacting the workpiece or the flat bottom while releasing the supplied gas through the tip and the ignition gas injection hole, the spark roller rotates. Therefore, the ignition stone (lighter stone), which had been pressed and contacted with a spring outside the spark roller, was rubbed, and sparks were generated to ignite the gas discharged to the ignition gas injection port first, and then to the tip (furnace) to ignite. After the ignition, the user can adjust the flame to the desired size, and the primary flame will be extinguished automatically and the air will be sucked through the ignition gas injection port to mix the gas, oxygen, air, in the injector to save oxygen. To provide an auto-oxygen saving torch.

      The present invention is to further improve the automatic ignition gas cutting machine pre-registered and pre- filed by me to provide an automatic oxy-fuel cutting machine of another principle.

      Conventional gas cutters, which are commonly used, are not equipped with a device that can automatically ignite the sparks, so there was a great danger when igniting the sparks. In other words, the conventional gas cutting machine does not have a device for igniting the flame, so when igniting the flame, the ignition of the flame is generally ignited by using a separate ignition mechanism such as a matcher, an industrial lighter, etc. Use the tool to ignite the ignition first, then operate the oxygen supply valve and gas supply valve to release the mixed gas from the tip, bring the spark from the ignition to the tip, and discharge the mixture through the tip by the spark from the ignition. The gas was ignited to produce a powerful spark.

       As such, the conventional gas cutting machine, which is used to ignite the flame by a manual method, is inconvenient to carry a separate ignition mechanism, and it is necessary to eject the mixed gas generated at the tip. It was not easy to adjust it, and there was a problem that often occurs a safety accident such as burns in the process of ignition.

        In order to solve such a problem of the conventional gas cutting machine, I am proposing to the automatic ignition gas cutting machine and the patent application No. 10-2003-0017295 to be registered in the patent No. 0413748.

        The automatic ignition gas cutting machine proposed in Patent No. 0413748 is to generate a flame while releasing a mixed gas mixed with gas and oxygen through a tip, and an oxygen amount adjusting valve is provided inside the valve bundle provided at the rear of the handle. It can be provided to supply the amount of oxygen required to work the workpiece, but can be controlled by a valve or lever provided on the upper side of the handle, the front end of the handle is provided with an ignition button to easily ignite the flame, The present invention relates to an automatic ignition gas cutting device formed by varying the supply structure of oxygen and gas supplied according to capacity and characteristics, and supplying by mixing oxygen and gas used for ignition and spark generation or supplying in a separated state. It can be used appropriately according to the capacity (size) and usage. When mixing and supplying oxygen and gas for spark generation, it is possible to improve the thermal power by mixing while spraying, and when supplying the ignition button without supplying oxygen and gas used for ignition, it is safer. Although it was possible to use it, the ignition nozzle was exposed to the outside, and foreign matters accumulated in the ignition spring, and thus there was a problem in life due to ignition failure or breakage of the ignition spring. In addition, there was a problem that the wind blows, or the ignition rate is low during outdoor altitude work.

        In order to solve this problem, the automatic ignition gas cutter of Patent Application No. 10-2003-0017295, which is improved, grabs the handle of the cutter with the right hand, opens the gas valve with the left hand, and then holds the ignition grip and retracts. As the ignition valve is opened, the piezoelectric element (piezo) is pressed to generate electricity to generate primary ignition nozzles and sparks, so that the spark ignited inside the ignition unit reaches the ignition gas pipe for ignition without being affected by wind. When the ignition grip is released after ignition by reaching the tip of the tip with a strong flame, the ignition flame is extinguished and the door of the ignition unit is closed, preventing foreign matter from penetrating and being affected by the wind. The small cutter had difficulty in application.

The present invention has been made to further improve to solve the above problems to provide an automatic oxy-storage torch applied to various models of countries around the world.

The present invention is to provide an automatic ignition oxygen saving torch to save oxygen by using a mixture of air.

The present invention provides an auto-oxygen-saving torch that can be ignited and operated more easily without changing hands.

The conventional torch is detachably fastened using a nut 28-1, as shown in Figs. 4A and 4B, and the seed 27 is assembled in a direction opposite to the valve pin 26-1. Since the seed 27 and the valve pin 26-1 do not coincide with each other due to the movement of the screw 27-2, the valve pin 26-1 is severely damaged and the outflow of oxygen occurs. The automatic oxy-storage torch 1 of 1 is integrated as shown in Fig. 3a and 3b. As the valve pin 26-1 moves with the screw through the inside of the seed 27, the center is precise and there is no leakage of oxygen. (26-1) Provides an automatic flash oxygen reduction torch that eliminates damage and eliminates the cause of backfire.

SUMMARY OF THE INVENTION The present invention provides an automatic oxy-storage torch with a gas and oxygen supply connector in which a hose connection part forms a sawtooth-shaped groove and a U-shaped groove to connect a general hose and use a one-touch connector directly. .
