The present invention relates to a piezoelectric ignition type gas lighter having a flame burner and a flameless burner.

In a conventional piezoelectric ignition type gas lighter, the piezoelectric igniter discharges electrical energy to ignite and burn liquefied gas fuel ejected from the fuel valve into the air. Such ignition and combustion include flame combustion standing long from the fireball, and flameless or internal flame combustion in which gaseous mixtures of gas fuel and air are burned in a hollow wind cylinder to stand very short from the fireball. The flames on the gas lighter's crater are fragile and allow the user to cover the crater by hand because the fire often goes out while the user lights a cigarette outdoors. The flameless flame on the crater is very short and powerful in length and is a combustion of the gas mixture, so that the flame does not extinguish in the light of a strong wind, making it very easy to light a cigarette outdoors. However, flameless flames have the drawback that they are more difficult to light a cigarette than flame flames. These flaws are very short in flames, so if the tip of the cigarette is not near the crater, the cigarette will not ignite, and since the cigarette is positioned obliquely in the crater, only the tip of the cigarette will burn in contact with the crater, causing the user to burn the entire tip of the cigarette. It is necessary to inhale the cigarettes for some time so that the fire is evenly burned, and the flameless gas lighter can sometimes not be used in these places because these noises are relatively loud and surprisingly raised in quiet rooms.

Unexamined Japanese Patent Application Laid-open No. 3-186114 discloses a flame and flameless gas lighter to overcome the above-mentioned drawbacks. However, such a gas lighter must be smaller than normal so that the flame burner nozzle's outer diameter is smaller than normal to provide a smaller flame nozzle's inner diameter because the flame burner nozzle is located directly above the internal flame or flameless burner nozzle in the hollow windshield cylinder. There is a tendency for the flame burner nozzles to be clogged with foreign matter in the gas fuel, making them difficult to clean. In addition, since the flameless burner nozzle acts as a discharge electrode, when the flame and flameless burner nozzles are damaged, none of the flame and flameless burners can be used and the gas lighter can be used.

SUMMARY OF THE INVENTION An object of the present invention is to provide a gas lighter having a new structure which can be used by switching both of flame and flameless or internal flame burners installed side by side.

It is a further object of the present invention that a simple means can switch between two fuel passages to the flame and flameless burners so that the need for a fuel valve on the flameless burner side is eliminated, each burner having an ignition electrode to ignite The idea is to provide a new gas lighter that the electrodes can always ignite.

Still another object of the present invention is to provide a gas lighter in which one piezo igniter can ignite each burner, and the connection of the lead wire on the flameless burner side is simple and easy to assemble.

In order to achieve these objects, the gas lighter of the present invention includes a tank for storing liquefied gas fuel, an accommodating portion for accommodating a piezoelectric igniter, and a lighter body for accommodating a fuel valve mounted in the tank and made of synthetic resin; A metal holder mounted to the lighter body; A hollow cylindrical assembly having a hollow intermediate cylinder made of ceramic, a hollow bottom cylinder made of metal and an upper open end, and an internal burner made of an electrically conductive material supported at the lower end and the inner surface of the cylindrical assembly via an insulating material A nozzle, a discharge electrode provided on the inner burner nozzle with a discharge gap, and electrically connected to the bottom cylindrical portion, connected to a lower end of the inner burner nozzle, beneath an air hole and the air hole, and liquefied gas on the fuel. A flameless burner comprising a fuel and air mixing tube having an orifice for ejecting and installed in the metal holder such that the bottom cylinder is electrically connected to and fixed to the metal holder; An outer burner nozzle made of an electrically conductive material fixed to the metal holder, and a discharge electrode provided on an upper portion of the outer burner nozzle and extending through an insulating material disposed on a side of the outer burner nozzle; A flame burner installed in parallel with the flame burner and sharing the fuel valve with the flameless burner; Flame free including a shut-off valve installed in the fuel passage to the flame burner, and an actuator installed in the lighter case to operate the shut-off valve to switch the flow of liquefied gas fuel between the flame and flame burners And a fuel passage switching means to the flame burner; The piezoelectric igniter has two leads, one lead wire electrically connected to the internal burner nozzle via the air and fuel mixing tube and the other lead wire electrically connected to the discharge electrode of the flame burner; Due to the significant difference between the diameter of the orifice and the inner diameter of the outer burner nozzle of the flame burner, it is possible to direct all of the liquefied gas fuel through the fuel passage to the outer burner nozzle when the fuel passages are open. do.

In the present invention, due to the significant difference between the inner diameter of the outer burner nozzle of the flame burner and the diameter of the orifice in the inner burner nozzle of the flame burner, there is a significant difference in the passage resistance of the fuel passage of the flame burner and the fuel passage of the flame burner. The liquefied fuel gas is introduced into the fuel passage of the flame burner when the shutoff valve is opened.

The discharge electrode of the flameless burner is in the form of an annular thin metal plate, and is electrically connected to the bottom cylindrical portion and the intermediate cylindrical portion, and the insulating material supporting the inner burner joule can insert the discharge electrode of the flameless burner.

A hook at the front end of one lead wire engages the loop of the electrical connection terminal, which is inserted into and electrically connected to the fuel and air mixing tube such that the one lead wire is electrically connected to the junction connection terminal.

The igniter has a (+) high voltage lead and a (-) high voltage lead, and each of the (6) and (-) high voltage leads is electrically connected to one burner nozzle either of the discharge electrode or the nozzle of the flameless and flame burner.

When the current from one piezo igniter is electrically discharged to the flame burner and flameless burner, only the burner that ejects the liquefied gas fuel is operated, and the burner which does not receive the liquefied gas fuel is not operated.

The switching means has a burner selection valve actuating lever installed in the burner selection valve, so that the shutoff valve and the actuator are movably installed in the lighter case.

The switching means comprises a movable arm for entering and exiting the space between the bar-shaped means for operating the fuel valve and a burner selection valve such as a shut-off valve, and the corner being pivotable to the tank, one end of which is one end of the bar-shaped actuating means. An L-shaped link pivoted into an actuator bar and an actuating bar such as an actuator movably mounted perpendicularly to the side wall surface of the lighter case, wherein a part of the actuating bar protrudes out of the opening defined by the side wall of the lighter case. The bottom end of is pivoted to the other end of the L-shaped link.

In the present invention, the user can select one of the flame burner and flameless burners according to the situation. Since the flame and flameless burners have respective discharge electrodes, the user can ignite the cigarette even if either flame or flameless burners are broken. In addition, because the flame and flameless burners are arranged side by side, the outer burner nozzle of the flame burner has a sufficiently large inner diameter so as not to be clogged by foreign matter in the gaseous fuel mixture. Since simply opening and closing the fuel passage of the flame burner switches between the fuel passage of the flame burner and the fuel passage of the flameless burner, the fuel valve of the conventional flameless burner can be removed, and only the fuel valve should have a flow regulator. do. Even the preparation of two burners does not complicate the internal structure of the gas lighter and does not increase the size of the gas lighter. Therefore, the present invention can make a gas lighter which is easier to handle than a gas lighter having conventional flame and flameless burners. Since the middle cylinder of the cylinder assembly of the flameless burner is made of ceramic material to reflect the red flame of the inner burner nozzle when using the flameless burner, the user can use the conventional flameless burner even when using a gas lighter in the dark or light. It is easier to check the operation of the flameless burner on the side of the gas lighter than the operation of.

Although the discharge electrode of the flameless burner in the form of an annular thin metal plate is located between the intermediate cylindrical portion and the insulating material supporting the cylindrical portion of the cylindrical assembly, the discharge electrode of the flameless burner is the discharge electrode of the flameless burner. Since it is electrically connected to the bottom cylindrical portion, it is possible to generate an electric arc crossing the discharge gap in the same manner as the conventional gas lighter. Since the engagement of the hooks of the lead wires of the loops of the connection terminals can be arranged at the same time as the igniter is placed in the accommodating part of the lighter body and the lead wires can be electrically connected to the connection terminals in the assembly of the gas lighter, the gas lighter assembly labor is reduced. do. Since the igniter has positive and negative voltage leads, the discharge electrodes discharge at the same time, and the electrical energy required for the ignition discharge can ensure that the two burners do not fail to ignite.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 show a gas lighter according to the first embodiment of the present invention.

The gas lighter includes a lighter body 1 made of synthetic resin. The lighter main body 1 includes a liquefied gas fuel tank 2 and a receiving portion 4 for the piezoelectric igniter 3. The lighter body 1 defines a space on the upper wall of the tank 2. The metal holder 7 is screwed to the upper surface of the lighter body 2. The holder 7 holds the windshield cylindrical assembly 8 of the arch of the flameless burner 5 and the outer burner nozzle 9 of the flameburner arranged side by side on the space.

The lighter body 1 has a fuel valve 10 provided on the upper wall of the tank 2 or the lower surface of the space. The fuel valve 10 is a conventional structure in which a fuel discharge tube 12 serving as an actuator for a valve body in a casing of the fuel valve 10 is installed to be movable vertically on the valve casing of the fuel valve 10. The upper end of the fuel discharge tube 12 has a fluid relay member (11). The upper wall of the fluid relay member 11 has an outlet connected to the outer burner nozzle 9 of the flame burner 6, and the side wall of the fluid relay member 11 has an inner burner nozzle 29 of the flameless burner 5. Has an outlet connected to it. The fuel valve operating bar 13 extends obliquely between the fuel discharge tube 12 and the side of the igniter 3, so that the front end of the fuel valve operating bar 13 is fitted on the fuel discharge tube 12.

The second flexible fuel passage tube 14 made of synthetic resin or rubber is connected to the lower end of the inner burner nozzle 29 of the flameless burner 5 from the outlet at the side wall of the fluid relay member 11. Extends to (33). Thus, the flameless burner 5 is in continuous fluid communication with the fuel valve 10. The first fuel passage tube 15 made of the same material as the second fuel passage tube 14 is wound around the support 16 extending downward from the lower bracket 7a of the holder 7. And extends from the outlet at the top wall of the burner to the lower end of the outer burner nozzle (9) of the flame burner (6). Thus, the outer burner nozzle 9 of the flame burner 6 is in fluid communication with the fuel valve 10.

As shown in FIG. 3, the winding portion of the first fuel passage tube 15 may squeeze a portion of the first fuel passage 15 in cooperation with the support 16 to close the first fuel passage tube 15. It has a horizontal bar-shaped burner selector 17 that can be. The front end of the burner selector 17 is bent backwards, and the rear end of the burner selector 17 is screwed into the metal cover 18 covering the space above the tank 2. The front face of the burner selector 17 has a selector actuator 19 superimposed thereon as shown by dashed lines in FIG. The selector actuator 19 has a wedge shaped rear face (not shown) in contact with the front face of the burner selector 17 and is fitted into a horizontal groove (not shown) in the front wall of the lighter case 20.

The two leads 21, 22 extend from the igniter 3 so that the leads 21 are electrically connected to the internal burner nozzle 29 of the flameless burner 5 and the leads 22 are shown in FIG. 2. As shown, it extends from the back of the holder 7 through the insulating material 23 of the holder 7 and is electrically connected to the first discharge electrode 24 disposed directly above the outer burner nozzle 9 of the flame burner 6. Is connected.

The bottom of the igniter 3 is electrically connected to a flexible ground bar 25 extending out of the lighter body 1. The ground bar 25 extending between the lighter body 1 and the lighter case 20 includes a lighter case 20, a cover 8, a holder 7, a windshield cylindrical assembly 8, and an outer burner nozzle 9. Provide a ground consisting of:

As shown in FIG. 3, the igniter actuator 26 covers the moving element 3a of the igniter 3. The bottom end of the igniter actuator 26 has a side protruding constrictor 27 for the fuel valve actuating bar 13. The retractor 27 is fitted to slide in the groove in the cover 18 and is disposed at the upper or rear end of the fuel valve actuating bar 13.

As shown in FIG. 4, the flameless burner 5 mainly consists of a windscreen cylinder 8, an internal burner nozzle 29, a second discharge electrode 30, and a fuel and air mixing tube 33. As shown in FIG. The windshield cylindrical assembly 8 includes an upper hollow inner cylindrical part 8c made of metal, a hollow upper outer cylindrical part 8b that is screwed to an outer cylindrical surface of the inner cylindrical part 8c, and an intermediate hollow cylindrical part made of ceramic. (28), a bottom outer cylindrical portion 8a made of metal, and a hollow insulating support inner cylindrical portion 34. As shown in FIG. The inner burner nozzle 29 is made of an electrically conductive material and is disposed in the bottom outer cylindrical portion 8a and the insulating support inner cylindrical portion 34, which is a coaxial line of insulating material. The second discharge electrode 30 is in the form of an annular thin metal plate and fits the inner cylindrical surface of the bottom outer cylindrical portion 8a which is electrically connected to the bottom outer cylindrical portion 8a. The second discharge electrode 30 has a second discharge gap and is disposed directly above the internal burner nozzle 29. The insulating intermediate cylindrical portion and the insulating support inner cylindrical portion 34 sandwich the second discharge electrode 30 therebetween. The outer edge of the second discharge electrode 30 is fitted to the inner surface of the bottom outer cylindrical portion 8a and electrically connected to the bottom outer cylindrical portion 8a. The fuel and air mixing tube 33 is made of an electrically conductive material and is screwed into the outer cylindrical surface of the bottom end of the inner burner nozzle 29 to be inserted into the insulating support inner cylindrical portion 34. The middle side wall of the fuel and air mixing tube 33 has an air intake 31. The bottom end of the fuel and air mixing tube 33 has a plate defining an orifice 32 under the air inlet 31 for introducing fuel gas into the internal burner nozzle 29. The diameter of the orifice 32 is significantly smaller than the inner diameter of the outer burner nozzle 9 of the flame burner 5. Therefore, the passage resistance of the second fuel passage 14 is such that almost all liquefied gas fuel is guided to the outer burner nozzle 9 through the first fuel passage tube 15 when the fuel passages 14 and 15 are opened. It is much larger than the passage resistance of the one fuel passage tube 15.

The bottom outer cylindrical portion 8a is fitted to be fixed to the hole in the lower bracket 7a of the holder 7. The upper outer cylindrical portion 8b is fixed to the upper bracket 7b of the holder 7 which defines the crater 42 of the flame burner 6. The cylindrical portion 28 is sandwiched between the bottom and upper outer cylindrical portions 8a and 8b intermediate cylindrical portion 28. The bottom outer cylindrical portion 8a includes an annular inner shoulder portion for supporting the inner burner nozzle 29 and the insulating support inner cylindrical portion 34 for supporting the first discharge electrode 30.

An electrical connection terminal 36 having a loop 35 is fitted around the bottom end of the fuel and air mixing tube 33 so that the loop 35 lies on the side of the igniter 3. The outer flange 37 of the fuel and air mixing tube 33 and the screw cap 39 screwed to the outer cylindrical surface of the bottom end of the fuel and air mixing tube 33 have an electrical connection terminal 36 therebetween. Insert in. The lowermost inner shoulder of the cap 39 securely supports the bushing 38 to align the open ends of the opis 32 and the second fuel passage tube 14. The inner shoulder of the bushing 38 and the inner cylindrical surface of the bottom end of the cap 39 having a reduced diameter fix the second fuel passage tube 14.

The hook at the front end of the lead wire 21 of the igniter 3 is engaged with the loop 35 of the electrical connection terminal 36 so that the internal burner nozzle 29 is connected to the fuel and air mixing tube 33 and the electrical connection terminal. 36, and the lead wire 21 is electrically connected to the igniter 3. As shown in FIG. 4, the annular crater with the wire 40 of the catalysis is fitted in the upper inner cylindrical portion 8c. As shown in FIG. 3, the windshield 41 integrally formed with the cover 18 surrounds the fireballs of the flame and flameless burners 6, 5.

In operation, depressing the igniter actuator 26 presses the rear end of the fuel valve actuating bar 13 to open the fuel valve 10 so that the liquefied gas is discharged from the two fuel passage tubes 14, 15 outside the tank 2. Are discharged). Since the diameter of the orifice 32 communicating with the inner burner nozzle 29 of the flameless burner 5 is much smaller than the inner diameter of the outer burner nozzle 9 of the flame burner 6, the second fuel passage tube 14 The passage resistance of) is much greater than the passage resistance of the first fuel passage tube 15, and almost all the liquefied gas passes through the first fuel passage tube so as to be ejected from the outer burner nozzle 9. The current from the igniter 3 actuated by further pressing the igniter actuator 26 is at the upper end of the outer burner jog 9 to ignite the liquefied gas ejected from the upper end of the outer burner nozzle 9. An electric arc intersects the first discharge gap between the coil discharge electrode 9a and the needle discharge electrode 24 to generate a spark from the fireball 42.

On the other hand, sliding the selector actuator 19 horizontally pushes the front end portion of the burner selector 17 toward the rear, so that the burner selector 17 and the support 16 are connected to the first fuel passage valve 15. Press to close. As a result, the liquefied gas is discharged to the second fuel passage tube 14 outside the tank 2. The ejection of liquefied gas from the orifice 32 is directly above the orifice 32 in the fuel and air mixing tube 33 to introduce air through the air inlet 31 into the fuel and air mixing tube 33. Generates sound pressure in the area. Therefore, the fuel mixture gas is blown into the insulating support cylinder 34 from the air outlet at the side wall of the internal burner nozzle 29.

Electricity from the igniter 3 is discharged simultaneously in the flame burner 6 and the flameless burner 5. Since the burner selector 17 is in the closed position of the first fuel passage tube 15 to stop the supply of liquefied gas fuel to the flame burner 6, the electricity from the igniter 3 is transferred to the internal burner nozzle 29. Of the flameless burner 5 such that the electric wick crossing the second discharge gap between the discharge electrode 30 and the discharge electrode 30 ignites the gas mixture ejected through the lifesaving on the side of the front end of the internal burner nozzle 29. The internal burner nozzle 29 is ignited. Therefore, the gas mixture is combusted in the windshield cylindrical assembly. Since this combustion proceeds to a high temperature, the intermediate cylinder causes the heat of combustion to be reflected by the red combustion light, which can be observed through the holes in the windshield 41.

Therefore, selecting the use of the first fuel passage tube 5 or the second fuel passage tube 14 prior to the operation of the igniter 3 only requires that only one of the flame burner 6 and the flameless burner 5 be used. It can work.

5 to 9 show a gas lighter according to the second embodiment of the present invention. In general, elements of the gas lighter according to the second embodiment that are identical to the first embodiment use the same reference numerals, and descriptions of the same elements are omitted. In summary, the outer burner nozzle 9 of the flame burner 6 is integrated into the fluid relay member 11 to form the burner selection valve 11, and the burner selection valve 11 is the first of the flame burner 6. It is possible to switch between the fuel passage 15 and the second fuel passage of the flameless burner 5. Further, the positions of the flameless burner 5 and the flameless burner 6 of the gas lighter according to the second embodiment are opposite to those of the gas lighter according to the first embodiment.

The bottom end of the cylindrical valve casing of the burner selection valve 11 has a fuel inlet 11a. The side wall of the valve casing of the burner selection valve 11 has a fuel outlet 11b. The outer burner nozzle 9 of the flame burner 6 is cylindrical and has an outer flange 9a in the middle. A part of the outer burner nozzle 9 below the flange 9a passes through the bushing 11c screwed into the inner cylindrical surface of the upper end of the valve casing of the burner selector valve 11 into the valve casing. The outer burner nozzle 9 can move vertically, and the bottom end side wall of the outer burner nozzle 9 has a through hole 9b. The coil spring 9d, which sits between the lower side of the bushing 11c and the spring retainer 9c at the bottom of the outer burner nozzle 9, has a burner with a through hole 9b below the lower side of the bushing 11c. Tighten the outer burner nozzle 9 downward so as to be exposed into the valve casing of the selector valve 11. Therefore, the liquefied gas that has passed through the first fuel passage 15 passes through the inside of the valve casing of the burner selector valve 11, the through hole 9b, the inside of the outer burner nozzle 9, and the upper portion of the outer burner nozzle 9. Pass outside the end one after the other.

The front end of the curved burner selector operating lever 43 is fixed to the lower side of the flange 9a of the outer burner nozzle 9. The burner selector operating lever 43 may be pivoted about an axis at the edge of the burner selector operating lever 43 along the inner surface of the lighter case 20. The bottom end of the burner selector operating lever 43 engages the operating block 19a of the selector actuator 19 installed to slide horizontally on the lighter case 20. The operation block 19a is horizontally thin and long, and is coupled to the selection actuator 19a by a screw 19c penetrating the horizontal groove 20a. The actuating block 19a has a cam surface 19b that pushes the bottom end of the burner selector actuating lever 43 backwards when it is moved horizontally to one end of the groove in the lighter case 20.

The burner selection valve 11 communicates with the fuel valve 10 through the fuel discharge tube 12, the first fuel passage 15, and the fuel inlet 11a at the bottom end of the valve casing of the burner selection valve 11. . The internal burner nozzle 29 of the flameless burner 5 communicates with the burner selection valve 11 through the fuel and air mixing tube 33, the second fuel passage tube 14, and the fuel outlet 11b. Therefore, the liquefied gas fuel introduced into the burner selection valve 11 through the normally open fuel valve 10 is introduced into the hollow interior of the inner burner nozzle 29 and the bottom end of the fuel and air mixing tube 33.

The igniter 3 held in the lighter body 1 is completely electrically insulated from the lighter case 20. The igniter 3 has two leads 21 and 22 at the top and the bottom. The positive high voltage lead wire 21 is electrically connected to the internal burner joules 29 of the flameless burner 5 in the same manner as in the first embodiment. The negative high voltage lead wire 22 is electrically connected to the first discharge electrode 24 penetrating the insulating material 23 of the holder 7, and the external burner nozzle 9 of the flame burner 6 is connected to the first discharge gap. Provided directly above.

In operation, pressing the igniter actuator 26 first presses the rear end of the fuel valve actuating bar 13 to open the fuel valve 10. At that time, the liquefied gas fuel is introduced into the valve casing of the burner selection valve 11 outside the tank 2 in the open position through the open fuel valve 10. Since the diameter of the orifice 32 in the fuel and air mixing tube 33 is much smaller than the inner diameter of the outer burner nozzle 9 shown in FIG. 7, the pressure resistance of the second fuel passage tube 14 is It is much larger than the pressure resistance inside the hollow of the outer burner nozzle 9. Therefore, almost all the liquefied gas fuel in the valve casing of the burner selector valve 11 is introduced into the outer burner nozzle 9 and ejected from the upper end of the outer burner nozzle 9.

Further pressing of the igniter actuator 26 activates the igniter 3 to simultaneously generate positive and negative high voltage electricity. The positive high voltage electricity leads the lead wire 21, the electrical connection terminal 36, the fuel and air mixing tube 33, the internal burner nozzle 29, and the internal burner nozzle to generate an electric arc crossing the second discharge gap. The second discharge gap, the second discharge gap 30, the bottom outer cylindrical portion 8a, the lower bracket 7a of the holder 7, and the cover 18 between the 29 and the second discharge electrodes 30. And it passes through the lighter case 20 sequentially. On the other hand, (-) high voltage electricity is the upper portion of the lead wire 22, the first discharge electrode 24, the first discharge electrode 24 and the external burner nozzle (9) to generate an electric arc crossing the first discharge gap The first discharge gap between the coil electrodes 9a at the end, the coil electrode 9a at the upper end of the outer burner nozzle 9, the valve casing of the burner selector valve 11, the cover 18 and the lighter case ( 20) pass sequentially. These positive and negative high voltage electricity is discharged at the same time. However, since the internal burner nozzle 29 of the flameless burner cannot receive liquefied gas fuel, the electric arc generated by crossing the second discharge gap in the flameless burner 5 is discharged from the flameless burner 5. The liquefied gas fuel cannot be ignited, and only the first discharge gap in the flame burner 6 is ignited to burn the liquefied gas fuel so that the spark of electric arc generated is ignited from the outer burner nozzle 9. Although the electrical connection from the cover 18 to the lighter case 20 is removed, this electrical connection can be removed because ignition by electrical discharge can be made.

On the other hand, the front end of the burner selector operating lever 43 rotates in a clockwise direction as shown in FIG. 8 with respect to the axis at the corner of the burner selector operating lever 43 so as to lift the outer burner nozzle 9. In order to close the through holes 9b of the outer burner nozzle 9 against the force of the coil spring 9d, the sliding of the selector actuator 19 first moves the bottom end of the burner selector operating lever 43 to the operating block. Tighten backward by means of the cam surface 19b of 19a. The cam surface 19b may be selectively formed to push the bottom end of the burner selector operating lever 43 when the user slides the selector actuator 19 horizontally. Continuously pressing the igniter actuator 26 presses the rear end of the fuel valve actuating bar 13 to open the fuel valve 10. By this means, the liquefied gas fuel is introduced into the burner selection valve 11 and introduced into the fuel and air mixing tube 33 through the second fuel passage tube 14. The ejection of liquefied gas fuel from the orifice 32 creates a negative pressure in this region so that air is introduced into the inner region of the fuel and air mixing tube 33 directly above the orifice 32. Therefore, the gaseous fuel and the mixed gas are blown into the windshield cylindrical assembly 8 through the through holes in the side wall of the inner burner nozzle 29.

Further pressing of the igniter actuator 26 causes the igniter 3 to generate an electric arc crossing the second discharge gap to ignite the fuel gas mixture ejected from the holes in the sidewall of the internal burner nozzle 29. Works. By this, the fuel gas mixture is combusted in the windshield cylindrical assembly 8. In this case, the user can easily observe a very short flame from the outside of the windshield 41 that is erected from the crater at the upper end of the windshield cylindrical assembly 8.

10 and 11 show an alternative burner selection of a very useful gas lighter that can simultaneously open and ignite the lighter cap. This burner selection part is disposed in a space in front of the front end of the fuel valve operation bar 13. The burner selector is an arm 44 provided so as to be movable between the front end of the fuel valve actuating bar 13 and the burner selector actuating lever 43 provided in the burner selector valve 11, and one end is the front of the arm 44. It consists of an L-shaped link 45 connected to the arm 44 so as to pivot to an end and a burner selector operating bar 46 connected to the L-shaped link 45.

The L-tongue link 45 consists of an upper arm and a lower arm 47. The edge of the L-shaped link 45 is supported to be pivotable by pivot means 48 on a bearing 49 which is fastened to the upper wall of the tank 2. The upper end of the upper arm of the L-shaped link 45 pivots to the front end of the arm 44. The front end of the lower arm 47 is pivoted by the pivot means 50 to the bottom end of the selector operating bar 46. The rear face of the burner selector operating bar is in continuous sliding contact with the fixing guide 51, and the front face of the upper end of the burner selector operating bar 46 is also continuously perpendicular to the inner surface of the side wall of the lighter case 20. Is in sliding contact. This side wall of the lighter case 20 defines a vertical flaw 52 for manually operating the selector operating bar 46. The front middle portion of the selector operating section 46 has a section 53 that protrudes through the groove section 52. Vertical movement of the section 52 moves the selector operating bar 46 vertically.

As shown in FIG. 10, when the arm 44 is in the disengaged position from the fuel valve actuating bar 13, the upper inclined surface of the front end of the fuel valve actuating bar 13 and the arm 44 are pivoting means ( There is sufficient space in between for the front end of the fuel valve actuating bar 13 to rotate upwards with respect to 13a). Therefore, pressing the igniter actuator 26 to press the rear end of the fuel valve actuating bar 13 only closes the fuel valve 10, but the fuel valve actuating bar 13 opens the burner selector operating lever 43. Do not combine. The burner selection valve 11 remains open, so that liquefied gas fuel flows from the fuel valve 10 to the flame burner 6 in the same manner as the first and second embodiments of the present invention.

As shown in FIG. 11, the lower end of the arm 44 is arranged in a notch in the upper surface of the fuel valve actuating bar 13 behind the upper slope of the front end of the fuel valve actuating bar 13. When the 44 is in the position to engage the fuel valve actuating bar 13, the igniter actuator 26 presses the rear end of the fuel valve actuating bar 13, the fuel valve actuating bar 13 is the arm 44. By means of the burner selector operating portion 43 can be raised. Therefore, as described above, the fuel valve 10 is opened, and at the same time, the burner selection valve 11 is closed so that liquefied gas fuel flows from the fuel valve 10 into the internal burner nozzle 29 of the flameless burner 5. .

With the burner used, this switching can be done by simply moving the segment on the burner selector operating lever 43 by the user's forefinger holding the gas lighter. That is, raising the section 53 on the burner selector operating lever 43 with the front end of the index finger is the lower arm of the L-shaped link 45 to rotate the L-shaped link in the clockwise direction in FIG. Raise 47 to move arm 44 to fuel valve actuating bar 13 such that the rear end of arm 44 engages the notch in the upper surface of fuel valve actuating bar 13. On the other hand, pressing the section 53 with the front end of the index finger rotates the L-shaped link 45 counterclockwise in FIG. 11 to separate the arm 44 from the fuel valve operating bar 13. Move (44) forward.

It is to be understood that the invention is not limited to the embodiments described in the specification, and that those skilled in the art can readily modify the invention without departing from the spirit of the invention as defined by the claims.
