Description

  The present invention relates to a gas lighter equipped with a fire extinguishing mechanism that reliably extinguishes the afterglow of the gas lighter after use of the gas lighter, in particular, even if fuel gas leaks due to a failure in opening and closing the valve mechanism of the ejection nozzle, The present invention relates to a gas lighter equipped with a fire extinguishing mechanism that cuts off the flow of leaked gas and reliably extinguishes fire.

  2. Description of the Related Art Conventionally, a gas lighter performs fire extinguishing by deliberately performing a fuel gas ejection and an ignition operation by means of an intentional operation as means for igniting a cigarette or the like, and canceling the state of the intentional operation.

  Even if the operation is canceled and the fire extinguishing state is restored, fuel gas may leak without completely closing the jet nozzle valve due to dust entering the jet nozzle valve or between the jet nozzle and the gas lever. is there. If the ignition state (afterfire) is sustained by such a leaked gas, there is a possibility of developing into an accident such as an unexpected burn or fire.

Therefore, in order to ensure fire extinguishing when the operating state of the gas lighter is released, the jet nozzle is opened only during operation, and the jet nozzle is closed with a burner cap during non-operation to extinguish the residual fire. Such gas lighters are disclosed in the following patent documents.
JP 2001-108234 A Japanese Unexamined Patent Publication No. 7-158852

  The gas lighter described in Patent Document 1 is provided with a set button that is operated simultaneously with the operation button, is provided with a burner cap that opens to the left and right in conjunction with the set button, and always surrounds the ejection nozzle that ejects fuel gas with the burner cap When the set button is pushed down, the burner cap opens left and right to expose the ejection nozzle. After using the lighter, release the finger from the operation button to shut off the gas with the automatic return of the operation button. Even if the fuel gas leaks due to some trouble, the jet nozzle is surrounded by a burner cap that returns to the surrounding state by the elasticity of the return rubber so that the residual flame caused by the leaked gas is extinguished.

  However, since this gas lighter has a burner cap that opens and closes to the left and right around the ejection nozzle, there is a problem that the space that the burner cap extends to the left and right must be provided in the cap, and the fire extinguishing mechanism cannot be reduced. There is. In addition, the burner cap must be operated by operating a set button different from the ignition button, which is troublesome.

  In the gas lighter described in Patent Document 2, the shutter provided on the operation button is brought into contact with the outlet of the ejection nozzle that constantly ejects fuel gas when not operated, and pushed forward from the ejection nozzle by pushing out the operation button during ignition operation. The gas passage is opened, and after using the gas lighter, the finger is released from the operation button, so that the gas is shut off with the automatic return of the operation button and the shutter stays on the ejection nozzle. .

  However, in this gas lighter, since the shutter is pushed forward, a large space must be provided in front, and there is a problem that the fire extinguishing mechanism cannot be reduced. In addition, since the shutter is cantilevered by the operation button, there is a problem that a backlash gradually occurs due to frequent operations.

  Therefore, the gas lighter provided with the fire extinguishing mechanism of the present invention has been conceived in order to solve such a problem, and the movable space of the fire extinguishing mechanism is reduced to simplify the configuration and operation. .

  The gas lighter according to the present invention includes a lid member that moves in conjunction with the operation button in the gas lighter that causes the fuel gas to be ejected from the ejection nozzle by operating the operation button and that activates an ignition mechanism to ignite the fuel gas. Provided, the lid member is in a position to suppress the ejection of the fuel gas on the ejection nozzle when the operation button is not operated, and has a fire extinguishing mechanism that moves to a position where the ejection of the fuel gas is opened when the operation button is operated. It has.

  The gas lighter according to the present invention includes a lid member that is in a position that suppresses the ejection of fuel gas on the ejection nozzle when the operation button is not operated, and moves to a position that opens the ejection of fuel gas when the operation button is operated. By providing a fire extinguishing mechanism, fuel gas continues to leak from the ejection nozzle due to malfunction of the gas lever that opens the valve mechanism in the ejection nozzle, malfunction return due to dust clogging of the nozzle moving part, etc. Even if it exists, the ejected gas hits the lid member by returning the lid member to the fixed position, and the gas is blocked or diffused, so that the residual fire can be extinguished reliably.

  In the gas lighter of the present invention, the lid member of the fire extinguishing mechanism can be smoothly rotated, and the fire extinguishing mechanism can be reduced in size, so that it can be provided inside the cap that forms a flame. The appearance and design are not affected, and the operation is the same as a conventional gas lighter.
