Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a burner valve device for a liquefied gas lighter, and particularly to a burner valve device in which a burner nozzle moves up and down to open and close the valve.

[Conventional technology]

Conventionally, burner valve devices for liquefied gas lighters have been known in which a valve body is attached to a fuel storage tank and the valve is opened and closed by moving up and down a burner nozzle that extends upward from the valve body. be.

In such burner valve devices, there is a gap between the valve body and the burner nozzle, so there is a risk that dirt and dust may enter this gap during long-term use and cause valve closing failure. . Particularly in the case of lighters that generate sparks for ignition by rubbing a flint with a pyrotechnic file, there is a high risk that flint powder will enter the gap and cause valve closing failure. .

However, in the past, such garbage,
No proposal has been made to prevent dust, flint powder, etc. from entering between the valve body and the burner nozzle.

[Means for solving problems]

This idea effectively seals the gap between the valve body and the burner nozzle without obstructing the vertical movement of the burner nozzle, and eliminates dirt, dust, and flint powder in the gap between the valve body and the burner nozzle. This burner valve is installed in the fuel storage tank of a liquefied gas lighter and is opened and closed by moving the burner nozzle up and down. A protective cylindrical body having a length corresponding to the amount of rise of the burner nozzle and flexibility corresponding to vertical movement is installed between the valve body and the burner nozzle, thereby sealing the gap between the valve body and the burner nozzle. .

〔Example〕

Preferred embodiments of this invention will be described below with reference to the drawings. In the figure, 1 is a casing body of a liquefied gas lighter, and a fuel storage tank 2 is provided inside. 3 is a burner valve that communicates with the fuel storage tank 2 to control and release fuel gas to the outside, and includes a valve body 4 fixed to the fuel storage tank 2, and a burner valve 3 that is movable up and down on the valve body 4. The valve is opened and closed by moving a valve body 6 made of rubber or the like fixed to the lower end of the burner nozzle 5 into and out of contact with the valve hole 7 of the valve body 4. The burner nozzle 5 is formed with a gas passage 8 whose lower end communicates with the inside of the valve body 4 and whose upper end opens to the upper end of the burner nozzle 5, allowing fuel gas to be ejected from the fuel storage tank 2 when the valve is opened.
The burner nozzle 5 is normally biased in the valve closing direction by a spring 9. A gasket 10 is disposed between the valve body 4 and the fuel storage tank 2 to maintain airtightness between the two.

Reference numeral 11 denotes a flexible protective cylinder made of rubber, synthetic resin, etc., which is disposed between the nozzle holding member 12 and the burner nozzle 5, which constitute a part of the valve body 4, and whose upper end is connected to the burner nozzle. 5, and its lower end is tightly attached to the nozzle holding member 12. The protective cylinder 11 has a length corresponding to the ascending distance of the burner nozzle 5 and a shape with free flexibility that does not inhibit vertical movement. A gap 13 between the burner nozzle 5 and the nozzle holding member 12 is sealed by the protective cylinder 11 disposed between the burner nozzle 5 and the nozzle holding member 12.
There is no possibility that dirt, dust, flint powder, etc. will enter this gap 13.

14 is a pyrotechnic file wheel for rubbing the flint 15;
Reference numeral 6 denotes a lever member that moves the burner nozzle 5 up and down in response to opening and closing of the lid 17.

[Operations and effects of the invention] According to this invention, the burner valve is installed in the fuel storage tank of a liquefied gas lighter and is opened and closed by moving the burner nozzle up and down. A protective cylindrical body with a length corresponding to the amount of rise of the burner nozzle and flexibility corresponding to vertical movement is installed between the valve body and the burner nozzle to close the gap between the valve body and the burner nozzle. There is no risk of dirt, dust, flint powder, etc. entering the gap between the valve body and the valve body.
In addition to ensuring stable valve opening and closing operations over a long period of time, the protective cylinder has a predetermined length and flexibility, so there is no hindrance to the vertical movement of the burner nozzle to open and close the valve. There is no danger that it will come.
