Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a combustion device for burning gas fuel, and in particular, although the intention is not limited to this, it relates to a windshield gas lighter for igniting a cigarette.

(Prior Art) For example, a general gas lighter includes a fuel tank having a fuel discharge nozzle, an ignition device (a high-pressure discharge device or a flint ignition mechanism for igniting the gas),
It also includes an operating mechanism that drives the fuel discharge nozzle upward or downward, and then or before that drives the ignition device to ignite. Conventionally, the ignition flame usually rises from the flame port of the outer case (or inner case) of the lighter (if the nozzle itself is exposed, there is no flame port; in this case, the tip opening of the nozzle). Since the gas flow velocity is relatively low, the flame's upward momentum is relatively weak, and in the presence of wind, the flame extinguishes as soon as it ignites. Therefore, in the past, the side of the flame was surrounded by a cylindrical body or the like to reduce the direct impact of the wind on the flame (windshield lighter).

(Problem to be solved by the invention) A cylindrical body is used to surround the flame as a windshield, but it is necessary to supply air to the fuel gas emitted from the nozzle and apply sparks or flint sparks. For this reason, it is necessary to open an air supply port or a spark port in the cylindrical body, which poses the problem of reducing the windshield effect. Furthermore, since there is a cylindrical body for windshield, cleaning around the nozzle is difficult and maintainability is low.
Furthermore, spark ignition devices have the problem that it is difficult to arrange the discharge electrodes, and complicated elements are required for mounting the discharge electrodes and wiring the power supply lines to the discharge electrodes.

The first purpose of the present invention is to provide a gas combustion device that is easy to maintain and has a high windshield effect, and the second purpose is to provide a windshield gas combustion device that allows easy and simple high-voltage power supply for gas ignition. shall be.

[Structure of the idea]

Support cylinder 2 having an opening at the upper end and a female thread on the inner circumferential surface; having a male thread on the outer peripheral surface that is screwed into the female thread of the support cylinder 2, and the lower end abuts the upper surface of the outer flange of the insulator cylinder 3. Fixed ring 6; stored in the support tube 2;
Catalyst support ring 8 whose lower end abuts the upper end of the fixed ring 6 and holds the catalyst wire in the central opening; is inserted into the support cylinder 2 and has a male thread on its outer circumference that is screwed into the female thread of the support cylinder 2; A presser ring 9 that is in contact with the upper end of the catalyst support ring 8; the upper part is connected to the inner space of the lower part of the insulator cylinder 3, and the intake port 5h is provided on the side surface below the lower end of the insulator cylinder 3, and the fuel a gas mixing pipe 5 having a gas inlet and an inner space communicating with the inlet and the fuel gas inlet;
It has an inner space that communicates with the inner space of the gas mixing pipe 5,
and has an opening 4h that communicates with the inner space and discharges the mixed gas in the inner space into the upper space of the insulator cylinder 3,
It includes a mixture nozzle 4 inserted into the inner space of the upper part of the insulator cylinder 3; and ignition means for igniting the mixed gas between the insulator cylinder 3 and the catalyst wire.

The windshield gas combustion device of the present invention also includes () a hollow insulator 3; supporting means 2, 6 for a conductor supporting the insulator 3, surrounding the upper side surface thereof, and having an opening at the upper end; an output terminal; One of the output terminals is electrically connected to the support means 2, 6, and the other output terminal has a tip end shaped like a coil, and a high voltage for generating an ignition spark is generated between these output terminals. High voltage generating means 24; the upper part is inserted into the inner space of the lower part of the insulator 3, and has an intake port 5h on the side surface below the lower end of the insulator 3, and a fuel gas inlet below the inlet port 5h. a gas mixing tube 5 made of a conductor and having an inner space communicating with an intake port and a fuel gas inlet of the high voltage generating means, and passing through a coil hole at the tip of the coiled winding shape of the high voltage generating means; It has an inner space communicating with the inner space of the mixing tube 5, has a discharging tip 4t at the upper end, and has an inner space between the discharging tip 4t and the support means 2 and 6 for the conductor. An ignition nozzle 4 made of a conductor is provided, which has an opening 4h communicating with the inner space for supplying a mixed gas, is inserted into the inner space in the upper part of the insulator 3, and is connected to the gas mixing tube at the lower part.

(Function) () The facility gas that has entered the fuel gas inlet of the gas mixing pipe 5 is mixed with air from its intake port, and the mixed gas flows from the inner space of the gas mixing pipe 5 into the mixture nozzle 4. It exits to the upper space of the insulator cylinder 3 through the space. The ignition means 24 ignites this mixed gas, so that a flame is generated within the support cylinder 2 and rises from the central opening of the catalyst support ring 6 to the upper part of the support cylinder 2 across the catalyst wire. The catalyst wire is heated by this flame and becomes red hot. Catalyst wire also has an anti-inflammatory effect, so
The flame above the catalyst wire is pale in color and difficult to see, but if you hold the tip of a cigarette above the catalyst wire, it will ignite.

Since the combustion gas is mixed with air within the support tube 2, there is a flame, and the flame within the support tube 2 is difficult to extinguish even by wind. When a relatively strong wind enters the support cylinder 2 from the upper part of the catalyst wire, this flame will also be temporarily extinguished. However, if the catalyst wire generates heat and is at a high temperature, its oxidation-promoting effect causes the mixture to become a flame when it comes into contact with the mixture. Therefore, even if the flame disappears temporarily, it will reappear. Due to the combustion promoting effect of the catalyst, the windshield effect is higher than when there is simply a cylinder.

Then, the fixing ring 6 is screwed into the support tube 2, the outer flange of the insulator tube 3 is sandwiched between the inner flange of the support tube 2 and the lower end of the fixing ring 6, and the fixing ring 6 is tightened to insulate the support tube 2. Body cylinder 3
, screw the presser ring 9 into the support cylinder 2, sandwich the catalyst support ring 8 between the fixing ring 6 and the presser ring 9, and fix the catalyst support ring 8 above the fixing ring 6 by tightening the presser ring 9. Therefore, remove the catalyst support ring 8 from the support cylinder 2 by reversing the assembly order and clean the area around the catalyst wires fixed to the catalyst support ring 8 and the inner space of the support cylinder 2. I can do it. In this way, maintainability is high.

The windshield gas combustion device of the present invention also has the following features: (1) The supporting cylinder 2 and the fixing ring 5 are made of electrical conductors, and the ignition means is used as the high voltage generating means 24, and one of the output terminals thereof is
One of the output terminals is electrically connected to the support tube 2 and the fixing ring 5, and the other end of the output terminal is formed into a coiled winding shape, and the conductor gas mixing tube 5 is passed through this coiled winding part. There is. A conductive ignition nozzle 4 having a discharging tip 4t at its upper end is inserted into the inner space of the insulator tube 3 and connected to the gas mixing tube 5. That is, one of the output terminals of the high voltage generating means 24 is connected to the support tube 2 and the fixing ring 6, and the other is connected to the ignition nozzle 4,
The former and the latter are insulated by an insulator cylinder 3.

When the high voltage generating means 24 generates a high voltage for ignition, the support tube 2, the fixing ring 6 and the ignition nozzle 4
This voltage is applied between the discharging tips 4t to generate a discharge spark, which ignites the mixed gas being supplied to the inner space of the support tube 2 from the opening 4h of the ignition nozzle 4. This ignition generates a flame that burns within the support tube 2 and passes upward through the inner space of the support tube 2.

Since the support tube 2 and the fixing ring 6 serve as one pole for high-pressure discharge, and the gas mixing tube 5 serves as the other pole, there is no need to add a special discharge electrode, and the discharge electrode is connected to the support tube 2. Since no special means for retraction is required, the ignition mechanism is extremely simple. In addition, in the case of one pole for supplying high voltage for ignition, the gas mixing tube 5 is simply passed through the coiled winding portion, so there is virtually no need for electrical connection work, and the assembly work is simple.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 shows an exploded view of an embodiment of the present invention. A fuel nozzle 20 is attached to the fuel tank 17, and in this embodiment, by pulling up the fuel nozzle 20, a gas release valve opens in the fuel tank 17, and the fuel in the fuel tank 17 is vaporized. It comes out from the nozzle 20. The fuel tank 17 is made of transparent synthetic resin, and the remaining amount of liquefied fuel inside can be visually observed from the outside of the tank. This fuel tank 17 is integrally formed with a side trunk 19 that guides a high pressure generator 24 and a support trunk 18 that supports a burner unit (2, etc.).

The high voltage generator 24 is a so-called piezoelectric unit, which has a piezoelectric element that generates high voltage in response to a strike and a mechanism that strikes the piezoelectric element, and the piezoelectric element is housed in a main body case 24c made of an insulator. A metal base 24f supports one end of this piezoelectric element. A high voltage lead 24h is connected to the other end of the piezoelectric element. High voltage lead 2
The leading end of the 4h wire is stripped of its insulating coating to expose the conductive wire, and is wound around a coil of a predetermined radius with a length of 24w. The main body case 24c has an operation case 24.
i is attached, and an impact coil spring and plunger are housed in this operating case 24i. A conductive layer having the same potential as the base 24f is exposed on the outer surface of the head of the operating case 24i. When the operating case 24i is pressed down, the coil spring is compressed, the plunger is unlocked at a certain position, and the plunger is driven downward by the repulsive force of the spring and strikes the piezoelectric element. At this time, the piezoelectric element applies high voltage to the base 24df and the operating case 24i.
(usually referred to as ground) and coil 24w (usually referred to as the high voltage pole).

When assembling the lighter, open hole 1 of fuel tank 17.
Insert the receiving plate 22 and the rubber plate 23 into 7r. Next, the operating element 21 is passed through the support shaft 18 between its two legs 21f ₁ and 21f ₂ , and the engagement groove 21r is inserted into the nozzle 2.
It is inserted under the flange 20f of 0 and attached to the support stem 18 in such a manner that the fulcrum protrusion _21P2 is engaged with the groove 18r of the support stem 18.

Pass the leg sleeve 5s of the mixing tube 5 through the coil 24w of the piezoelectric unit 24, and
Insert the orifice plate 10, washer 11, and filter 12 in this order into the leg sleeve 5.
The male thread on the outer periphery of the tip of the flange pipe 13 is screwed together with the inner female thread of s, and the elastic synthetic resin tube 15 fixed to the lower part of the flange pipe 13 is passed through the rubber O-ring 16.

Next, the operator 25, which is formed by pressing a metal plate, is placed over the operating case 24i of the piezoelectric unit 24.
Support arm 1 and operator 25 fixed to support tube 2
and the piezoelectric unit 24 as a set, the base 24f of the piezoelectric unit 24 is connected to the hole 17 of the fuel tank 17.
r, lower leg 1f of support arm 1, and operator 2.
5 and the piezoelectric unit 24 are inserted between the support stem 18 and the side stem 19 of the fuel tank 17. In this way, the semicircular protrusions 25f ₁ , 25f ₂ formed by pressing the operating element 25 become the legs 21f 1 , 25f ₂ of the operating element 21,
21f ₂ from above. Hole 1 of support arm 1
h is aligned with the hole 18h of the support stem 18. If the operator 25 is pressed down in this state, the piezoelectric unit 2
As the operation case 24i of No. 4 is pushed down,
The actuator 21 is connected to the protrusion 21P ₂ (groove 18r of the support stem 18
(supported by) in a clockwise direction to pull the nozzle 20 upward (release of fuel gas from the nozzle 20).

Next, the lower end opening of the elastic synthetic resin tube 15 is fitted over the nozzle 20 up to the flange 20f, and the O-ring 16 is inserted into the flange 20f of the nozzle 20.
Lower it to near 0f. This allows O-ring 16
Then, the lower end of the elastic synthetic resin tube 15 is tightened against the circumferential surface of the nozzle 20.

As described above, the operator 2 is placed in the fuel tank 17.
1. When the support arm 1, operator 25 and piezoelectric unit 24 are assembled, they are attached to the lighter case 2.
6 through the lower opening 26b, and
The hole 18h is the upper opening 26h of the lighter case 26.
Push it out so that it comes out higher. and top lid 28
straddle the legs 28f ₁ and 28f ₂ fixed to the support arm 18 and align their holes 28h ₁ and 28 ₂ with the hole 1h of the support arm 1 and the hole 18h of the support arm 18, and Pass the pin 29 through the top cover 28.
Push down the upper cap 28c toward the lighter case 26. When the upper cap 28c tightly closes the upper opening 26h of the lighter case 26, in this state, the triangularly protruding ends of the legs 28f ₁ and 28f ₂ of the upper lid 28 form a semicircle formed by pressing out the operator 25. It comes into contact with the upper ends of the shaped projections 25r ₁ and 25r ₂ .

Next, insert the hook 30 into the lower opening 26b of the lighter case 26, engage the protrusion 30p of the hook 30 with the inner groove 26r of the lighter case 26, close the lower opening 26b with the lower lid 31, and screw 32 to lower lid 31
Through the hole 31h and the hole 30h of the hook 30,
Screw it into the screw hole at the bottom of the fuel tank.

With the above steps, the lighter has been assembled.
When using the lighter assembled in this manner, the upper cap 28c of the upper lid 28 is rotated clockwise around the pin 29 with the thumb. Then, the legs 28f ₁ and 28f ₂ of the upper lid 28 drive the operator 25 downward. The downward movement of the operating element 25 drives the operating case 24i of the piezoelectric unit 24 downward, compressing the coil spring therein, and the operating element 21 rotates clockwise to pull up the nozzle 20. As a result, the discharge of fuel gas starts from the nozzle 20, and the discharged fuel gas is passed through the stretchable (elastic) synthetic resin tube 15 and the filter 1.
2. The center hole of the washer 11 and the orifice in the center of the orifice plate 10 (10h: Figs. 2 and 3)
It enters the mixing tube 5 through the tube and proceeds further upward. Due to this fuel gas flow, air is drawn into the mixing tube 5 through the intake port (5h: Figs. 2 and 3) opened on the circumferential surface of the mixing tube 5, and this air is mixed with the fuel gas.
The mixed gas flows from the mixing pipe 5 to the ignition nozzle (4: second,
3), enters the inner space of the support cylinder 2 through the opening 4h of the ignition nozzle, passes through the catalyst wire 7, and exits above the support cylinder 2.

When the top cover 28 is further rotated, the piezoelectric unit 24
The lock of the plunger in the operating case 24i is released, the plunger hits the piezoelectric element by the repulsive force of the coil spring, and high voltage is ignited in the support tube 2 from the coil 24w of the lead 24h via the mixing tube 5. The nozzle (4: Figs. 2 and 3) is connected to the fixing ring (6: Figs. 2 and 3) via the conductive layer of the actuating case 24i of the piezoelectric unit 24, the operator 25, the support arm 1, and the support tube 2. ) is connected to the low voltage (earth) pole of the piezoelectric unit 24, so that an electrical discharge spark occurs between the ignition nozzle 4 and the fixed ring 6. The discharge spark ignites the mixed gas in the support tube 2 to generate a flame, which heats the catalyst wire 7 and makes it red hot, promoting combustion of the mixed gas.

In this state, connect the tip of the cigarette to the catalyst wire 7.
When you bring it close to above, it will ignite.

FIG. 2 shows an enlarged view of the internal structure of the support tube 2, and FIG. 3 shows a cross-section taken along the line -2. Note that these drawings show the state immediately before the elastic synthetic resin tube 15 is connected to the nozzle 20.

The structure around the support tube 2 will be explained with reference to FIGS. 2 and 3. The metal (conductive) support tube 2 has a relatively thick inner flange at the lower end.
It has a substantially cylindrical shape with a small-diameter thin sleeve integrated below the inner flange, and a female thread 2s is cut on the inner wall surface. This support tube 2 is fixed to the support arm 1 by passing the small-diameter thin sleeve through a hole at the ring-shaped tip of the metal (conductive) support arm 1 and caulking the thin sleeve outward. ing. A ceramic (insulator) cylinder 3 is inserted into a hole in the inner flange of the support cylinder 2 from above. The ceramic tube 3 has an outer flange at the upper end and an inner flange at the center, and the lower surface of the inner flange is in contact with the upper surface of the flange of the support tube 2. The metal (conductive) fixing ring 6 has an inner flange at the lower end and a male thread on the outer peripheral surface.
The upper end surface has a groove 6s (FIG. 3) into which the tip of a flathead screwdriver (screwdriver) is inserted. By screwing the fixing ring 6 into the support tube 2, the upper end surface of the ceramic tube 6 is pressed down by the fixing ring 6,
As a result, the outer flange of the ceramic tube 6 is tightened by the inner flange of the support tube 2 and the inner flange of the fixing ring 6, thereby fixing the ceramic tube 6 to the support tube 2.

A metal (conductive) ignition nozzle 4 is inserted into the center hole of the inner flange of the ceramic cylinder 3, and a tip of a metal (conductive) mixing tube 5 is inserted into the lower opening of the cylinder 3. The mixing pipe 5 is fixed to the ignition nozzle 4 by screwing the male thread formed on the outer circumferential surface of the lower part of the nozzle 4 into the female thread formed on the inner circumferential surface of the mixing pipe 5. Both are fixed to the ceramic tube 3 by tightening the inner flanges of 3.

A catalyst support ring 8 that supports the catalyst wire 7 is inserted into the center of the support cylinder 2 through an opening at its upper end, and is supported by a fixing ring 6 . 6 at the top
The holding ring 9, which has a hexagonal hole 9h corresponding to the external shape of a square nut, has a male thread on its outer circumferential surface, and this male thread is screwed into a female thread 2s on the inner circumferential surface of the support cylinder 2. 6
By inserting and turning a hexagonal driver into the square hole 9h, the holding ring 9 is screwed into the support cylinder 2, and the catalyst support ring 8 is tightened by the holding ring 9 and the fixing ring 6.

The fixing ring 6 is attached to the support arm 1 via the support cylinder 2.
Since the support arm 2 is electrically connected to the conductive layer (ground electrode) of the actuating case 24i of the piezoelectric unit 24 via the operator 25, the fixing ring 6 is electrically connected to the piezoelectric unit 24
It functions as one discharge electrode (ground) connected to the ground.

The coil 24w at the tip of the high voltage lead 24h of the piezoelectric unit 24 is obtained by stripping the insulation of the high voltage lead 24h and winding its core wire (conductor wire) to a diameter slightly smaller than the outer diameter of the leg sleeve 5s of the mixing tube 5. A leg sleeve 5s is inserted into this coil 24w, and is held down by a gear-like flange 5f for screw driving of the mixing tube 5. As a result, the ignition nozzle 4 is electrically connected to the high voltage lead 24h of the piezoelectric unit 24 via the mixing tube 5 (note that even if there is a small gap, when high voltage is applied, the The gap is destroyed by electrical discharge and becomes conductive).
The tip of the ignition nozzle 4 is tapered into a small diameter cylinder, and has a relatively sharp circumferential edge at the top end. Therefore, when the piezoelectric unit 24 generates a high voltage, a discharge spark is generated between the circumferential edge and the circumferential edge of the inner flange at the lower end of the fixing ring 6. The ignition nozzle 4 has an opening 4h below the small-diameter cylindrical portion at the tip.

The mixing tube 5 has an orifice plate 10 in the center.
There is an inner flange for receiving air, and above the inner flange there is an intake port 5h for sucking in the air. Plate 10 having orifice 10h, washer 11 and filter 12 are inserted in this order into mixing tube 5 from the lower opening, flange tube 13 is screwed into the lower opening of mixing tube 6, and plate 10, washer 11 and filter 12 are inserted into mixing tube 5 from the lower opening. It is pressed against the inner flange of the mixing tube 6. A heat-resistant O-ring 14 is attached to the side circumferential surface of the flange pipe 13, and this maintains the airtightness of the threaded joint between the mixing pipe 5 and the flange pipe 13. The tip of a stretchable synthetic resin tube 15 is press-fitted into the flange tube 13, and is brought into pressure contact with the inner wall of the flange tube 13 due to its stretching force.

The nozzle 20 is pulled upward and the nozzle 20
When the fuel gas leaves, it passes through the synthetic resin tube 15 and then enters the mixing tube 5 through the filter 12, the central hole of the washer 11 and the orifice 10h of the plate 10, and then enters the ignition nozzle 4.
This flow of fuel gas causes the intake port 5 of the mixing pipe 5 to
Air is sucked into the tube 5 through h and advances to the ignition nozzle 4 while mixing with the fuel gas. A gas mixture of air and fuel gas, ie, a mixed gas, exits from the opening 4h of the ignition nozzle 4 into the inner space of the ceramic cylinder 3, and then advances to the inner space of the fixing ring 6.
When the ignition spark advances from the inner space of the ceramic tube 3 to the inner space of the fixing ring 6, the ignition spark passes through the ignition nozzle 4.
When the mixed gas is generated between the leading edge of the ring 6 and the periphery of the inner flange of the fixing ring 6, the mixed gas ignites and becomes a flame. The flame passes through the catalyst wire 7 and rises from the hexagonal opening 9h of the holding ring 9, but this flame makes the catalyst wire 7 red hot, and due to the combustion promoting action of the catalyst wire 7, the flame becomes pale blue. Or it becomes transparent. If you bring the tip of a cigarette close to the top of opening 9h, it will catch fire.

When the catalyst wire 7 is red-hot, even if a strong wind that blows out the flame temporarily hits the opening 9h and extinguishes the flame, the flame is regenerated in the catalyst wire 7 after the wind passes. Therefore, it has a windproof effect even against relatively strong winds.

When the upper lid 28 is closed, the nozzle 20 is lowered to stop releasing fuel gas and combustion.

It is difficult to drill screw holes in the ceramic tube 3,
Normally, a metal layer is formed on the surface by plating or vapor deposition, and the metal is welded to the metal layer to fix it to the metal, but in the embodiment described above, the support tube 2 and the fixing ring 6 are used to attach the ceramic tube 3 to the outside. Attach the support tube 2 to the ceramic tube 3 by tightening the flange.
is firmly attached. Processing is easy because plating and vapor deposition are not required. Since the catalyst support ring 8 is fixed to the support tube 2 by tightening the fixing ring 6 and the holding ring 9, when it is necessary to remove the catalyst wire 7, such as when cleaning around the catalyst wire 7 or the ignition nozzle 4, The presser ring 9 can be rotated and removed from the support tube 2, and the catalyst support ring 8 can be taken out, allowing non-destructive disassembly, cleaning, repair, etc. to be carried out easily and easily.

The ignition nozzle 4 and fixing ring 6 are used as they are as electrodes for discharging the high voltage of the piezoelectric unit 24, and the connection between the ignition nozzle 4 and the unit 24 is simply by winding the high voltage lead 24h of the unit 24 around the coil 24w. Simply passing the sleeve 5s of the ignition nozzle 4 through the coil 24w does not require soldering or screw clamping, making assembly simple and reliable.
