The present invention relates to an ignition promoting device to ignite safely and accurately when igniting gas appliances using butane gas outdoors.

Recreational gas appliances, mainly liquefied gas, are equipped with adapters at the bottom for coupling and separation with butane gas containers, and at the top of the adapters, knobs for adjusting gas paths and piezoelectric sparks generated during ignition. A gas valve equipped with a switch was provided, and a venturi tube for sending gas to an ejection pipe was provided at an upper portion of the gas valve, and a combustion member made of a blower tube or a burner in which the combustion state of gas was a light source was connected to an upper portion of the venturi tube. Made up.

An air inlet is formed between the venturi tube and the gas valve to receive external air required for gas combustion. Thus, gas and air are mixed at a predetermined ratio through the venturi tube to combust in the gas ejection tube.

In general, when gas is combusted, the ratio of combustion air is greater than that of gas, and when gas is ignited, efficient combustion and ignition are achieved only when the ratio of gas is higher than combustion air.

Therefore, in order to promote ignition in gas appliances and leisure gas appliances, a hole or a gap in which air can be introduced into the venturi tube is formed so that external air is always introduced into the gas ejection tube through the venturi tube. In the case of complete combustion, but the ignition is rather low at the time of ignition there was a problem that the ignition is not made at a time.

In addition, the gas gap between the venturi tube and the gas valve has a high concentration of gas at the time of ignition, so that gas leaks naturally between the gaps, resulting in a decrease in safety.

If the gas is leaked into the gap between the venturi tube and the gas valve as described above, if the ignition operation is performed by pressing the knob, the mixture of gas and air is in an unstable state, and thus an incomplete combustion state is achieved and the soot is the inner wall of the glass tube. A problem occurred that the illuminance of the light source was lowered during combustion.

Therefore, the space or through hole between the venturi tube and the gas valve of the gas appliance requires a safety member to prevent leakage due to the excessive supply of gas during ignition, and the safety member moves to a position that blocks the gap or the through hole only when the gas is ignited. In order to safely ignite the gas appliance for leisure by such a safety member, and complete combustion is prevented by preventing the leakage of gas as much as possible, it is possible to prevent contamination of the combustion part. Like the leisure gas appliance 1 shown in Fig. 1, a through hole 6 is formed on the side of the venturi tube 5 connecting the gas ejection tube 9 and the gas valve 2, and the venturi tube 5 is surrounded therein. Install a control plate (7) consisting of a shielding plate (7a) having an outer diameter of the circular arc surface and a lever (7b) protruding from one side of the shielding plate (7a) to a thin side, the lever (7b) of the control (7) Gas valve (2) The cover plate 7a is placed on the through-axis of the venturi tube 5 inside the holder 3 so as to be fixed in the form of point rotation in the holder 3 to be installed, and the lever 7b is a guide formed in the holder 3. The configuration of the ignition accelerator which protrudes outward through the hole and engages the knob 8 has been introduced.

In the conventional ignition accelerator, the ignition plate 7a covers the through hole 6 of the venturi tube 5 by moving the knob 8 protruding from the outer circumference of the holder 5 when the ignition is performed. ) By opening the gas path by rotating the knob 11 connected to the predetermined direction and pressing the knob 11 of the spindle 10 to generate a spark in the piezoelectric switch 12.

In this case, the blocking plate 7a blocks the through-hole 6 drilled in the venturi tube 5, thereby preventing the gas from flowing out as much as possible, and at the same time, the outside air is blocked from being introduced into the venturi tube 5. The concentration of the gas is increased to ignite the gas ejection pipe 9 or the burner (not shown) at one time, but after the ignition, the shielding plate 7a covering the vent hole 6 of the venturi pipe 5 is opened. Complete combustion takes place only when moving to a position, which can be forgotten and not opened.

As described above, if the through-hole 6 of the venturi tube 5 is closed after ignition, the gas ratio becomes higher than the air ratio, so that the combustion tube is incompletely burned and soot is generated. The soot burned on the inner surface of the glass, which lowered the illuminance of the gas, and the burner part of the other gas appliance was contaminated by soot.

This problem is caused by manually operating the screening plate of the ignition accelerator, which is very troublesome to use the ignition accelerator.

Therefore, in the conventional ignition accelerator, the convenience to facilitate the handling of the accelerator is required, the certainty of the ignition operation is required, and the technical skills required for the leisure gas appliance are controlled from the gas valve to the knob that controls the gas and ignition. I want to satisfy.

The present invention is designed to ignite and extinguish a flame in a gas appliance or leisure gas appliance, the control and ignition knob 90 is moved in the front and rear direction from the connector 80 and the connector for moving the spindle 97 left and right. It consists of a knob consisting of a knob which supplies gas to the left and right direction and presses it during ignition. In this case, when the ignition control and the pressing force of the ignition knob 90 is transmitted to the block 200 through the extension piece 210, the air inlet 310 of the venturi tube 300 is closed to the concentration of gas Is increased and at the same time removing the force applied to the knob after the ignition block 200 is configured to open the air inlet 310 closed by the elastic member 400 that is pressed during its own load or knob compression. Ignition accelerator.

The blocking unit 200 intermittently closing or partially closing and concealing the air inlet portion 310 formed between the gas valve 60 and the venturi tube 300 having the nozzle 66 coupled to the upper end thereof may be a venturi tube ( 300 is formed into an arc larger than the outer diameter, and the extension piece 210 is installed between the shielding rod 200 and the adjustment and ignition knob 90, but is extended by the guide hole 22 formed in the holder 20. While installing the 210, the end of the extension piece 210 faces the edge surface 91 of the knob 90 by the guide hole 22 formed in the holder 20.

The extension piece 210 is for transmitting the force transmitted to the ignition and adjustment knob 90 to the block 200, can be formed integrally with the block 200, after forming separately the block ( It can also be formed in a structure assembled to 200).

Since the blocking bar 200 should always be in a position to open a hole or a gap of the air inlet part 310, using the self load of the blocking bar 200 to move the blocking bar 200 to the first position. Elevated or descending the air inlet 310, or is provided with a separate elastic member 400 to the block and the holder 20 has a configuration to move back and forth toward the air inlet (310).

EXAMPLE

When the butane gas container 60 is connected to and separated from the disposable butane gas container, the gas valve 60 is inserted into a hole in the holder 20 in which the gas ejection pipe 40 and the glass pipe 30 are installed, and protrude into the concave upper surface 21. The venturi tube 300 having the air inlet 310 is coupled to the threaded portion 61 of the gas valve 60. The shape of the air inlet 310 formed at the circumference of the venturi tube 300 is generally circular and is formed in one place.

The concave upper surface 21 of the holder 20 has a guide hole for protruding the push piece 75 of the piezoelectric switch 70 installed inside the holder 20 and the extension piece 210 of the shielding rod 200. 22) 23 are formed.

Barrier stand 200 is installed as a concave upper surface 21 of the holder 20 is a semicircular shape having the same or greater than the outer diameter curved surface of the venturi tube 300, the support piece 212 is bored at both ends 211 is provided flat, and the extension lower part 210 is formed by extending the center lower side of the circular arc surface forward.

The elastic member 400 is coupled to the guide hole 212 formed by boring the supporting piece 211 which is flat on the semi-circular curved surface.

The elastic member 400 is composed of a guide rod 401 made of 'c' type and a coil spring 402 fitted to both ends of the guide rod, the ends of the guide hole of the support piece (211) 212, the bar 200 and the elastic member 400 is installed together with the concave upper surface 21 of the holder 20, the guide rod 4 ((0)) protruding from the concave upper surface 21 A state of being fitted to the support 24 is achieved.

In this configuration, while holding the handle 101 of the leisure gas lamp 100 to which the disposable butane gas container 10 is connected to a predetermined place, the control and ignition knob 90 is moved to a predetermined place. When the adjustment and ignition knob 90 is moved to the ignition side in the state, the gas path is opened by the spindle 97 of the gas valve 60, and when the knob 90 is pressed, the push piece 75 of the piezoelectric switch 70 is pressed. ) Is pressed and at the same time the extension piece 210 of the block 200 is also pressed.

When the extension piece 210 of the plugging block 200 is pressed, it moves toward the venturi tube 300 to block the air inlet 310, and when the push piece 75 of the piezoelectric switch 70 is pressed. Sparks are generated around the gas ejection pipe 40.

When the block 200 blocks the air inlet 310, the external air does not flow into the gas ejection pipe 40, so the concentration of the gas is naturally increased. In this state, the spark of the piezoelectric switch 70 is gas ejected. It is transmitted to the tube 40 to ignite the action.

At this time, since the gas is supplied and ejected to the gas ejection pipe 40 with a high concentration, it is ignited by only one ignition action.

And when the ignition in the gas ejection pipe 40 is to remove the force applied to the adjustment and the ignition knob 90, this is made by the state of releasing the hand in contact with the knob (90).

When the knob 90 is released, the coil spring 402 of the elastic member 400, which has been compressed so far, returns and pushes the support piece 211, thereby preventing the block 200 from being separated from the venturi tube 300. Achieve.

When the block 200 is separated from the venturi tube 300, the air inlet 310 is in a natural open state, and the outside air flows into the ejection pipe 40, so that the gas and air are in an appropriate mixing ratio. Is a complete combustion.

EXAMPLE

When the butane gas container 60 is connected to and separated from the disposable butane gas container, the gas valve 60 is inserted into a hole in the holder 20 in which the ejection pipe 40 and the glass tube 30 are installed, and protrude into the concave upper surface 21. An ordinary nut is coupled to the screw portion 61 of the gas valve 60 to fix it.

In addition, a nut is attached to the threaded portion 301 protruding from the upper surface of the support plate 50 by inserting the end screw portion 301 of the venturi tube 300 into the center of the support plate 50 fixed to the concave upper surface 21. When the 50 is installed on the concave upper surface 21, an air inlet 310 through which the combustion air flows is formed between the venturi tube 300 and the gas valve 60.

The concave upper surface 21 of the holder 20 forms a guide hole 22 into which the extension piece 210 of the plug 200 is fitted, and a guide hole into which the piezoelectric switch 70 is fitted between the gas valve and the holder. To form.

The blocking rod 200 installed as the concave upper surface 21 of the holder 20 is a cylindrical ring having an inner diameter larger than the outer diameter of the venturi tube 300, and has a height greater than the gap between the air inlets 310. Is formed.

The tip of the extension piece 210 is inserted into both sides of the blocking ring 200 of the cylindrical ring, and the end of the extension piece 210 is bent into a 'b' shape to adjust and ignite through the guide hole 22. The lever 90 is placed in the vicinity of the edge 91 of the frame to form a lever.

In such a configuration, while holding the handle 101 of the leisure gas lamp 100 to which the disposable butane gas container 10 is connected, the control and ignition knob 90 is moved to the ignition side in a state of moving to a predetermined place. Opening the gas path to the spindle 97 of the 60, after pressing the knob 90, the push piece 75 of the piezoelectric switch 70 is pressed and at the same time bent in the 'b' shape of the block (210) ) Will also be pressed.

When the extension 210 of the blocking stand 200 is pressed, the blocking stand 200 moves upwards as if being heard by the lever toward the upper side of the venturi tube 300 to prevent the gap between the air inlets 310. When the push piece 75 of the piezoelectric switch 70 is pressed, sparks are generated.

When the block 200 blocks the air inlet 310, the outside air does not flow into the gas path, so the concentration of the gas is naturally increased. In this state, the spark of the piezoelectric switch 70 is a gas ejection pipe ( 40) to ignite.

At this time, since the gas having a high concentration is ejected from the gas ejection pipe 40, the gas is ignited by only one ignition.

After the gas is ignited in the ejection pipe 40, the force applied to the adjustment and the ignition knob 90 is removed, which is achieved by releasing the hand in contact with the knob 90.

When the knob 90 is released, the block 200 in the lifted state is lowered by its own load so that the air inlet 310 is exposed, that is, the air inlet 310 is opened. To achieve.

When the block 200 opens the air inlet 310 of the venturi tube 300, the outside air flows into the venturi tube 300, and the air is mixed with the gas in an appropriate state so that the combustion tube 40 is completely burned. Will be achieved.

As described above, the present invention is a gas valve is fixed and the air inlet 310 formed for the complete combustion in the holder 20 of the gas for leisure gas 100, the gas ejection pipe and the glass tube is installed, the control of the flame and Dots, closed by the block 200 moving in the state of pressing the fire extinguishing knob (90), after ignition to return to its own load or elastic member 400 to open the air inlet 310 Since the ignition of the gas for leisure is made very easy, and prevents the outflow of the gas by blocking the air inlet 310 during ignition has the advantage of eliminating the risk factors as possible, when ignition The gas concentration is increased, and the composition of removing the incomplete element at the time of ignition by adjusting the concentration of gas and air at the time of combustion reduces the soot generation and has the advantage of continuously maintaining the illuminance of the gas.

The present invention can be applied to any combustion mechanism, as well as leisure gas appliances and gas appliances that connect the butane gas container directly in addition to leisure gas.
