Abstract

PURPOSE:To simplify the construction and facilitate the production of the titled device, by a method wherein a cap-shaped thick-wall soft elastic valve casing fixed to a lighter case is provided with a fuel passage, a porous elastic member is placed through a valve seat plate, a valve body is pressed by a spring force, and the valve is opened by a lever action. CONSTITUTION:When a nozzle valve rod 5 is pulled upwards by operating a pulling-up lever 6, a base part 52 having a large diameter is moved upwards against a spring 56 to open a valve hole 21. Accordingly, the base part 52 pushes a top part 13 of the valve casing 1 upwards, and an intermediate wall of the casing 1 is extended. Since a skirt wall 11 is fixed, a plug body 3 is stationary in position, and the valve seat plate 2 is displaced upwards as the cylinder wall is extended. Therefore, the porous elastic body 4 permits permeation of gases. Accordingly, a fuel A1 flows out to a nozzle 53 through a liquid-sucking pipe 32, a fuel passage 31, the elastic body 4, the valve hole 21, an axial hole 12 and a fuel passage 54, and is ignited. With this construction, the device can be easily assembled by only sequentially fitting the valve rod 5, the valve seat plate 2, the porous elastic body 4 and the plug body 3 into the axial hole 12, and flame can be easily adjusted.

Description

[Detailed Description of the Invention] The purpose of the present invention is to provide a means that has all the functions required in the use of a gas lighter, has a simple structure, and has a simple production means and can be produced at low cost. do.

The gas lighter's tinder valve requires a valve opening/closing function as well as a valve opening adjustment function that determines the size of the flame. Since this would be impossible otherwise, the on-off valve and the control valve have conventionally been provided separately. In particular, the opening degree of the control valve is mostly adjusted by rotating precision screws. Machining precision screws is not only expensive, but the related structure itself is complex and requires a large number of parts. Therefore, this invention was developed to replace such conventional fire [
This invention is the result of research and devising to eliminate the drawbacks of the one-valve device, provide all the functions required in practice, and realize low cost.This invention will be explained below with reference to the illustrated example. Here, the first embodiment shown in FIGS. 1 and 2, and the third embodiment shown in FIGS.
The second embodiment shown in FIG. 4 is different from the second embodiment only in the shape of the skirt wall 11 of the valve case 1 and the fixing means for the skirt wall 11, and the dimensions of the other parts are the same. Therefore, in explaining the operational steps and effects of the present invention, the steps from FIG. 1 to FIG. 4 will be described as a series of steps. In addition, Fig. 2, Fig. 3,
4, the illustration of the spring 56 shown in FIG. 1 is omitted.

That is, 1 is a valve case made of a cap-shaped thick soft elastic body, and a skirt wall 11 around the opening is fixed to the lighter case A. The fixing method may be any suitable method, but in the first embodiment, it is fixed by adhesive 7, and in the second embodiment, it is fixed by a circle m8 inserted from above. A valve seat plate 2 having a valve hole 21 and a plug body 3 are tightly fitted into the shaft hole 12 of the valve housing 1 . A fuel passage 31 is bored in the plug body 3, and this fuel passage 31 connects the shaft hole 12 of the valve housing and the fuel tank A1, and in the illustrated example, a liquid suction pipe 32 is provided. The positions of the valve seat plate 2 and the plug body 3 are the middle part of the axial length of the valve M1 and the bottom wall 1, respectively.
It is inside 1. A porous elastic body 4 is inserted between the valve seat plate 2 and the plug body 3. Reference numeral 5 denotes a crater valve ring having a small-diameter cervical canal 51 that is slidably and closely inserted into the top wall 13 of the valve housing, and a large-diameter base 52 that is located within the shaft hole 12 of the valve housing.
3 and the shaft hole 12' of the valve housing are bored,
It is also under the downward tension of a spring 56. Large mouth valve ring 5
A valve body 55 is provided at the bottom of the valve body. 6 is the lifting lever,
Its tip 61 engages with the large mouth valve ring 5. In this invention, as described above, the top wall 13 of the valve housing is raised by operating the lifting lever 6.

It was made by sea urchin.

This invention is constructed as described above, and since the valve housing 1 is made of a cap-shaped thick soft elastic body, by operating the lifting lever 6 and pulling up the spout valve ring 5, the large diameter base can be removed. 52 is the spring 56
The top wall 1 of the valve housing rises against the tension of
3 is pushed up by the base 52, and the intermediate portion of the cylindrical wall of the valve housing 1 expands. The plug body 3 is tightly fitted into the shaft hole inside the hem wall 11 of the valve case, and the hem wall 11 is connected to the lighter case A.
The position of the plug body 3 remains unchanged because it is fixed to the valve body 1. On the other hand, since the valve seat plate 2 is tightly fitted into the middle part of the valve housing 1, the position of the valve seat plate 2 changes as the valve housing cylinder wall expands. The position is displaced upward, and therefore the density of the poroelastic body 4 inserted between the valve seat plate 2 and the plug body 3 becomes coarse. At this time, the large mouth valve ring 5
is rising, the valve body 55 separates from the valve hole 21 as shown in FIGS. 2 to 4, the on-off valve opens, and the pressurized gas fuel in the fuel tank Al flows from the fuel tank A1 to the fuel passage 31. , the porous elastic body 4, the valve hole 21, the shaft hole 12 of the valve housing, and the fuel passage 54, and are emitted from the crater 54, and when ignited in the crater 63, a flame is generated. Figures 2 through 4 all show a state in which ignition is possible, but as shown in Figures 3 and 4, as the degree of rise of the large mouth valve ring 5 increases, the cylinder of the valve housing 1 increases. The degree of elongation of the wall also increases, and therefore the poroelastic body 4
The density of the poroelastic body 4 also becomes coarser, and the amount of fuel passing through the poroelastic body 4 also increases.

Thus, as the degree of pulling of the pulling lever 6 increases, the amount of gas released from the crater 53 increases, and the flame lengthens accordingly. Therefore, the user of the lighter can obtain a desired flame length by adjusting the operation of the lifting lever 6. According to experiments, the amount of lift of the crater valve ring 5 from the valve closed position shown in FIG. 1 to the valve fully open state shown in FIG. 4 is several II.
m, a satisfactory flame length was obtained when the distance displacement between the valve seat plate 2 and the plug body 3 was approximately 0.1 mm. Incidentally, it is extremely easy to provide the lighter case A with a position limiting member for the operating portion of the lifting lever 6 to prevent the flame from rising excessively due to excessive lifting of the large mouth valve ring 5.

Thus, according to the present invention, the flame can be easily adjusted without using a complicated and expensive flame adjustment mechanism such as a combination of a flame adjustment wheel, a precision screw, and a knurled member, which has been widely used in the past. When assembling the device, insert the crater valve ring 5, valve seat plate 2,
Assembling the valve device is completed by simply inserting the porous elastic body 4 and the plug body 3 in order and fixing the valve housing 1 to the lighter case A, which reduces production costs due to the small number of parts and simple shape. can be significantly reduced.
