Description

  The present invention relates to a structure of a releasable gas outlet valve, and is used in particular for an igniter, and causes a gas remaining in the outlet pipe to flow backward to be released to the outside, thereby burning a flame that burns at the igniter outlet. The present invention relates to a structure of a gas outlet valve that achieves a quick extinguishing effect and can provide a complete and safe igniter to the user by means of the gas outlet valve.

  As shown in FIG. 1, a conventional pressure igniter that is generally seen has a generally rectangular handle portion 10, and one end of the handle portion 10 is provided with a hollow pipe 11 extending a certain distance outward. 11 is provided with a pressure head 12. The inner diameter of the portion where the one end 121 of the pressure head 12 and the pipe 11 are connected is slightly large, but the inner diameter of the other end 122 is obviously small and the handle portion 10. A gas cylinder 13 is provided therein, and one end of the gas cylinder 13 is connected to a gas outlet valve 14, and the gas outlet valve 14 is attached with a screw sleeve 142 from the outside of the front end of the hollow platform 141. . The gas outlet nozzle 143 extends outward from the bottom end in the platform 141 and is exposed to the outside through the front end port 144 of the screw sleeve 142, and the end of the gas outlet nozzle 143 has a flange 145, and the gas outlet pipe 151 and an operating lever 15 is provided between the flange 145 of the gas outlet nozzle 143 and the screw sleeve 142.

  A protruding portion 146 is provided at a predetermined length between the outer diameter of the gas outlet nozzle 143 and the inner diameter of the screw sleeve 142, and a packing 147 and a spring are provided between the inner diameter of the screw sleeve 142 and the protruding portion 146 of the gas outlet nozzle 143. 148 are provided in order. Further, a hole 149 is provided at an inner diameter portion of the side wall of the gas outlet nozzle 143 adjacent to the platform 141, and an airtight packing 16 is interposed at the bottom end of the gas outlet nozzle 143 in the bottom end of the platform 141.

  As a result, when the operating lever 15 is pushed down (as shown in FIG. 2), the flange 145 of the gas outlet nozzle 143 is lifted and the bottom end of the airtight packing 16 is moved upward. The end is opened, the gas in the gas cylinder 13 enters from the open bottom end of the platform 141, and is ejected from the free end of the pipe 11 through the gas outlet pipe 151 along the arrow direction, and an ignition pipe (shown in the drawing). The flame is ignited through the main flame (not done).

  However, after the pressure type igniter made using the gas outlet valve 14 is ignited, a phenomenon that the flame disappears slowly occurs. Therefore, the user removes the operating lever 15 and the gas outlet nozzle 143 is removed. Will return to its original position, the gas in the gas cylinder 13 will be shut off, and the flame will be wrong if it is not burning continuously. However, this is not the case, and when the operating lever 15 is removed as shown in FIG. 1, the gas outlet nozzle 143 returns to its original position, and the gas-tight packing 16 at the bottom end of the gas outlet nozzle 143 has already been mounted. The bottom end of the gas cylinder 13 is sealed to shut off the gas in the gas cylinder 13, but the packing 147 in the front end port 144 of the screw sleeve 142 is still held in an airtight state by the spring 148. The gas remaining in the gas cannot be reversed due to the principle of airflow and pressure, but only leaks along the gas outlet pipe 151. That is, when the gas pressure in the gas outlet pipe 151 is larger than the external pressure, the gas inside constantly flows out from the free end of the pipe 11, and the flow stops when the pressure in the gas outlet pipe 151 becomes smaller than the external pressure. This is the main reason why the flame disappears slowly and also causes regrets that cannot be compensated for such as fire accidents.

  This kind of product has been well received by users at the same time in view of the fact that there is a trap related to the safety of the gas outlet valve in the traditional igniter as described above, and that it causes regret that cannot be compensated for such as a fire accident. Therefore, in order to solve the above problems based on the actual needs of the market and users, the inventor made use of years of experience engaged in this work, and after a long period of research and experiment, finally the present invention “can be released” We hope to develop a "gas outlet valve structure" and to provide a more perfect and safer igniter with this skillful invention.
