Description of the Related Art A gas writer disclosed in Japanese Utility Model Publication No. 3-45017 supplies a mixture of air and a fuel gas to an internal space of a hollow burner cylinder (3), and the mixture is supplied in the cylinder. To burn. Since the gas burns in the cylinder and the cylinder (3) prevents the external wind from blowing off the combustion gas, it is difficult for the wind to misfire. That is, there is a first wind resistance effect. In addition to this, a catalyst wire (7) is arranged in the combustion cylinder (3), and this is red-heated by the combustion gas. Even if strong wind enters from the upper opening of the combustion tube (3) and the combustion in the tube (3) disappears temporarily,
The heated catalyst wire (7) automatically reignites the mixture around it. That is, since the catalyst wire (7) that is red-heated by the combustion gas constantly burns the air-fuel mixture around it continuously, even if there is a temporary misfire due to strong wind, it will automatically re-ignite immediately, which is a high wind resistance effect. There is a secondary wind resistance effect due to the catalyst wire (7).

い場合にこの不安感が強くなる。A fuel gas receiving port is provided at the lower end, a gas ejection opening is provided at the upper end projecting into the combustion cylinder (3), and an air intake is provided at an outer surface between the gas receiving port and the gas ejection opening. A mixture of fuel gas and air is supplied into the combustion tube (3) from a gas mixing pipe (5) having a port, but the gas flow sucks air at a high speed from the intake port, whereby the gas mixing pipe ( 5) supplies a relatively high-speed air-fuel mixture to the combustion cylinder (3). Therefore, the combustion gas is discharged from the combustion cylinder (3) at a high speed. However,
As the fuel gas and air are well mixed,
(3) So-called red flames do not appear inside and outside, and the combustion gas is transparent or slightly bluish and difficult to see. When the catalyst wire (7) is provided, it glows red, so it can be easily confirmed that the ignition is carried out by looking inside the combustion tube (3) from above, but from the side, it is ignited.
It's not easy to tell if (there is a flame) or not. Since the combustion gas blows out at high speed, the fact that the flame is not visible is
Brings anxiety to The. This anxiety becomes particularly strong when the catalyst wire (7) is not provided.

い。すなわち第1次の耐風効果がある。When the combustion mode switching means (9, 10) is placed in the first position, the air inlet of the tubular member (2, 3) is opened by the first opening / closing means (7f).
(2a) is closed, and the second opening / closing means (7s) opens the air intake port (8c) of the pipe member (8). As a result, the fuel gas supplied to the opening (8d) at the lower end of the pipe member (8) is discharged from the upper opening (8d) of the pipe member (8).
From the a) to the inner space of the tubular member (2, 3), this fuel gas flow sucks air along the flow of the fuel gas flow from the air suction port (8c) and the inside of the pipe member (8). The fuel gas flow that rises up is mixed with air to form a fuel gas / air mixture, and exits from the upper end opening (8a) into the inner space of the tubular member (2, 3). Ignition means (1

Even if the combustion in (2,3) also disappears temporarily, the heated catalyst wire (4) automatically reignites the air-fuel mixture around it. That is, since the catalyst wire (4) that is red-heated by the combustion gas always continuously burns the air-fuel mixture around it, even if there is a temporary misfire due to strong wind, it automatically re-ignites immediately, which is a high wind resistance effect. A secondary wind resistance effect due to the catalyst wire (4) can be obtained.

える。When the combustion mode switching means (9, 10) is placed in the second position, the first opening / closing means (7f) causes the air inlet (2) of the tubular member (2, 3).
a) is opened, and the air inlet (8c) of the pipe member (8) is closed by the second opening / closing means (7s). As a result, the fuel gas supplied to the opening (8d) at the lower end of the pipe member (8) exits from the upper end opening (8a) of the pipe member (8) into the inner space of the tubular member (2, 3). Air inlet
Since (8c) is closed, the upper end opening (8a) of the pipe member (8)
The fuel gas is substantially free of air until it exits. On the other hand, since the air intake (2a) of the tubular member (2, 3) is open,
Air passes through it into the tubular members (2, 3) and mixes with the fuel gas exiting from the upper end opening (8a) of the tubular member (8), but the tubular member (8)
The fuel gas concentration is higher and the air concentration is lower at a position closer to the center line passing through the center of the upper end opening (8a). On the contrary, the farther from the center line, the lower the fuel gas concentration and the higher the air concentration. The ignition means (16) ignites the air-fuel mixture in the tubular members (2, 3), but this ignition occurs at a position slightly distant from the center line of the pipe member (8) and where the fuel gas concentration is relatively low. Occur. Due to this ignition, the flame rises from the tubular member (2, 3), but the air concentration is lower as it is closer to the center line of the pipe member (8), so the flame is a red outside like a candle or a match flame. It presents a flame. In this way, the flame, so-called ordinary red flame, can be seen, so that the user can easily recognize the ignition. When there is no wind outdoors or indoors, this red flame gives the user a feeling of tranquility.

耐風効果がある。When a piezoelectric ignition device (not shown) generates a high voltage to generate an electric spark 17 at the upper end of the mixing tube 8 and the tip of the lead 16, a spark on the path of the spark 17 or around it. The air-fuel mixture is ignited when the air-fuel mixture ratio is suitable for ignition. Since the air-fuel mixture main flow 18ag1 and the air-fuel mixture sub-flow 18ag2 have high flow velocities, the ignited combustion nuclei may be extinguished by cooling or blown off by the gas flow before they sufficiently spread, and thus ignition may fail. obtain. On the other hand, since the flow rate of the air-fuel mixture gentle flow 18ag3 is extremely low, the combustion nuclei generated there spread and become combustion gas, which is the air-fuel mixture sidestream 18ag2 and the air-fuel mixture main flow 1
Ignite 8ag1. That is, the mixture gentle flow 18ag3
When formed, the probability of ignition failure is lower than it would be without it. Due to the ignition of the air-fuel mixture, the internal space of the ceramic cylinder 3 becomes combustion gas, which causes the catalyst wire 4 to glow red and the upper end opening 3
Exit from a at high speed. The combustion gas is transparent or slightly bluish and ignites when the tip of the cigarette is brought close to above the opening of the holding nut 6. Since the holding nut 6, the ceramic cylinder 3 and the support cylinder 2 prevent the external wind from blowing off the combustion gas, the combustion gas is unlikely to misfire with respect to the wind. That is, there is a first wind resistance effect. In addition to this, since the catalyst wire 4 is red-heated by the combustion gas,
Even if a strong wind enters from the upper opening of the presser nut 6 and the combustion in the ceramic cylinder 3 temporarily disappears, the heated catalyst wire 4 automatically reignites the air-fuel mixture around it.
That is, since the catalyst wire 4 that is red-heated by the combustion gas always continuously burns the air-fuel mixture around it, even if a temporary misfire due to a strong wind causes immediate re-ignition, a high wind resistance effect, that is, the catalyst wire. There is a secondary wind resistance effect of 4.

Natural flame mode (Fig. 2) When the flame switching lever 10 is pushed down against the force of the compression coil spring 9 to the second position shown in Fig. 2, the outer flange 7f of the flame switching cylinder 7 is supported by the supporting cylinder. 2, the lower opening 2a of the support cylinder 2 is opened by retracting downward from the lower end surface of the support tube 2, the flow dividing opening 7b of the flame switching cylinder 7 is moved below the branch opening 8b of the mixing pipe 8, and the inner surface of the flame switching cylinder 7 is 0. Since it contacts the ring 15 and compresses it, the flow passage between the branch opening 8b of the mixing tube 8 and the flow dividing opening 7b of the flame switching cylinder 7 is blocked, and the lower sleeve 7s of the flame switching cylinder 7 is closed. The air inlet 8c of the mixing tube 8 is closed.

い。In this state, when the gas release lever 14 is rotationally driven counterclockwise and the fuel nozzle 13 is pulled up (the gas release valve of the fuel tank is opened), the fuel gas of the fuel tank is synthesized from the fuel nozzle 13. It flows through the resin tube 12 into the mixing tube 8 (gas flow 18 g), and the upper end opening 8 of the mixing tube 8
From a to the inner space of the ceramic cylinder 3 (fuel gas mainstream 1
8g1). Since the air inlet port 8c of the mixing tube 8 is closed, substantially no air is mixed in the gas flow 18g by the time it exits the upper end opening 8a. Air is sucked from the lower opening 2a of the support cylinder 2 by the main flow 18g1 of the fuel gas discharged from the upper end opening 8a, and the air flow 18a flows into the ceramic cylinder 3. A part of the gas flow 18g in the mixing pipe 8 passes through the branch opening 8b and exits into the space between the mixing pipe 8 and the flame switching cylinder 7, where the edge of the upper end opening 7a of the flame switching cylinder 7 and the mixing pipe 8. It goes out into the ceramic cylinder 3 through the space between the upper surface and the peripheral surface (fuel gas gentle flow 18g2). Main fuel gas flow 1 from upper opening 8a
Air is sucked from the lower opening 2a of the support cylinder 2 by 8g1, and the air flow 18a flows into the ceramic cylinder 3. Since the air flow 18a flows in so as to cover the fuel gas flowing upward from around the upper end opening 8a of the mixing pipe 8 from below, the fuel gas concentration is high and the air concentration is low in the space inside the ceramic cylinder 3 as it is closer to the central axis. . On the contrary, the high pressure lead 16
The fuel gas concentration is lower and the air concentration is higher as it is closer to the tip surface of the.

The air-fuel mixture is ignited when the air-fuel mixture ratio is suitable for ignition. Since the main flow of the fuel gas 18g1 has a high flow velocity, the ignited combustion nuclei may be extinguished by cooling or blown off by the gas flow before being sufficiently spread, so that ignition may fail. On the other hand, since the combustion gas gentle flow 18g2 has a very low flow velocity, the combustion nuclei generated in the atmosphere mixed with air spread to become combustion gas, which propagates to the combustion gas main flow 18g1 from the outside. That is, when the combustion gas gentle flow 18g2 is formed, the probability of ignition failure is lower than that in the absence thereof.

タバコの先端を近づけるとそこに火が付く。In this way, the flame rises from the ceramic cylinder 3, but like the flames of candles and matches, the fuel gas concentration is high at the center, so the center is oxygen deficient (internal flame),
Outer flame 18cf is red at the outer peripheral portion and the upper portion where the oxygen concentration is high. That is, a natural flame with a pale inner flame inside and a red flame outside the bottom rises from the ceramic cylinder 3. When the tip of the cigarette is brought close to this flame, it catches fire.
