Description

[Detailed description of the invention] (Industrial application field) This invention is an improvement of an internal combustion type gas lighter in which a fixed amount of gas is ejected without adjustment when the valve is opened, and ignition combustion takes place within the lighter body. Regarding.

(Conventional technology) Conventionally, a combustion tube, etc. was built into the lighter body.
Internal combustion type gas lighters in which gas is ignited and burned within the lighter body have already been devised.

For example, a fuel tank filled with combustion gas,
A mixing pipe that has an intake hole that sucks in air by the negative pressure generated by ejecting the combustion gas from the tank at an increased flow rate, and that promotes mixing of the fuel gas and air, and a flow rate of the mixed gas. A diffuser connected to the mixing pipe to decelerate and diffuse the gas, and a mixed gas with air at a flow velocity sufficient for ignition and combustion by further decelerating and diffusing the gas mixed with air by the diffuser. An internal combustion type gas lighter that performs ignition combustion within the lighter body is provided with a combustion tube connected to the diffuser for ignition and ignition means for igniting the combustible gas in the combustion tube. (Refer to Japanese Patent Application Laid-Open No. 1983-91431).

On the other hand, a tank top lid is airtightly integrated into the upper opening of the gas tank body, a fitting recess with the upper opening integrally molded inside the tank top lid, and a fitting recess with an upper opening formed inside the tank top lid, and a fitting recess with an opening in the bottom center of the fitting recess and inside the gas tank main body. a cylindrical lid-shaped nozzle spiral that is press-fitted into the fitting recess and has a through hole at the top end surface; A nozzle bottom stopper having a cylindrical bottom shape, a gas ejection nozzle that is incorporated into the valve chamber via a spring or the like and whose upper end protrudes outward from the through hole of the nozzle spiral, and a gas ejection nozzle that protrudes from the lower end of the gas ejection nozzle. a filter disposed below the nozzle bottom stopper to allow a certain amount of gas to pass through when the valve is opened; and an annular spacer and a stator applied to the lower surface of the filter; The transmission filter is clamped and fixed between the bottom surface of the bottom plug body and the top surface of the annular spacer and stator, so that the valve bottom is placed in contact with the top surface of the transmission filter, and the valve is fitted onto the outer periphery of the lower end of the valve. There was a gas lighter in which an O-ring was bonded to the upper edge of the annular spacer and the inner wall surface of the fitting recess to seal off the outflow of gas from the side direction (Japanese Patent Laid-Open No. 60-11020
(see publication).

on the other hand, a burner for a cigarette lighter operating using compressed gaseous fuel, comprising means defining a fuel injection orifice of diameter D ₁ and an intake bench lily aligned with said fuel orifice, having an effective diameter of D ₂ ; and means defining a bench lily having a length L ₂ and having an inner diameter aligned with said bench lily and having a length L 2;
_D2 ; a disc-shaped flame holder disposed inside the flame tube, the flame holder having a central hub and a plurality of circumferential openings disposed around the hub; and in a burner in which the distance between the orifice and the inlet of the bench lily is L ₁ and the total area of the openings is A, and further the flame holder is spaced a distance L ₂ from the outlet of the bench lily. , the flame tube has a diameter D ₄ of about 1/4 inch or less, and L ₁ /D ₂ = about 1.67, D ₂ /
D ₁ = approx. 17, L ₂ /D ₂ = approx. 3.33, L ₃ /D ₂ = approx. 1.5,
There was a lighter burner with D ₄ /D ₁ = about 118 and A/(D ₄ ) ² = about 0.05 (see US Pat. No. 3,915,623).

(Problem to be solved by the invention) However, in the structure of the internal combustion type gas lighter (Japanese Unexamined Patent Publication No. 63-914131) as described above, the fuel gas and air ejected toward the diffuser are diffused. Since the fuel gas is only dispersed radially by the cone (more specifically, the action of the downward cone), there is a problem that the mixing and diffusion of fuel gas and air cannot be achieved sufficiently, and combustion efficiency is also expected. It wasn't that good.

On the other hand, in the gas lighter disclosed in JP-A-60-11020, in which the bottom of the valve is placed in contact with the top surface of the transmission filter, there is not only an annular spacer on the bottom surface of the transmission filter, but also a separate stator. Moreover, since a suction core is also required to contact the stator, there are problems in that the number of parts increases and it takes time and effort to assemble. Coupled with the use of molecular sieves (special adsorbents made of synthetic fluorite), production costs were considerably high.

Incidentally, various valve mechanisms for such disposable gas lighters have already been devised, but for example, Japanese Patent Application Laid-Open No. 119917/1986 reduces production costs by significantly simplifying the valve structure. For disposable gas lighters, the permeation filter (low-pressure component) must be placed inside the gas tank.
Because it must be installed so that it is directly exposed to the space above the LPG liquid level, it takes time and effort to install the transmission filter, and if the gas lighter is swung or turned upside down, the transmission filter may be damaged by the liquefied gas. There were concerns that excessive wetting would affect the critical surface tension of the permeation filter, causing errors in gas permeability, and other negative effects on membrane properties.

Moreover, since the upper surface of the perforated metal foil, etc. that constitutes the transmission filter is not provided with a displacement prevention means, it is loosened and displaced especially due to gas pressure fluctuations or negative pressure when the valve is opened, and the gas permeation area fluctuates. It also had the problem of causing problems.

On the other hand, the lighter burner disclosed in U.S. Pat. No. 3,915,623 is equipped with blades that are partially punched out from the metal flame holder, which corresponds to the diffuser plate of the present invention, so that the flame holder does not The gas and air ejected toward the flame holder are once in a vortex state due to the action of the blades, but as they move away from the flame holder, the vortex state weakens, and the negative pressure that has passed through the opening of the flame holder becomes axially Combined with the strong action, the vortex mixing of the fuel gas and air was still insufficient.

Furthermore, such a flame holder is provided with an annular rim to facilitate insertion into the flame tube corresponding to the combustion tube of the present invention, and has blades protruding from the downstream side (above the flame holder), In addition, because of the hub in the center, the flame holder cannot rotate even if it receives fuel gas jetting out at high speed, and the kinetic energy of the gas jetting out at high speed is transferred to the flame holder itself. It was not possible to convert the rotational energy into rotational energy and sufficiently mix and diffuse the fuel gas and air.

The present invention was devised in view of the above problems, and it is easy to install an annular spacer, and it also eliminates the need to use separate members such as stators and nets to prevent the upper part of the transmission filter from changing due to gas pressure fluctuations, etc. It prevents displacement and ensures a constant gas permeation area, suppresses excessive wetting of the transmission filter and gas accumulation inside the holes or on the bottom surface of the filter, and also transfers the kinetic energy of the fuel gas jetting out at high speed to the diffusion plate itself. It is an object of the present invention to provide an internal combustion type gas lighter that can convert fuel gas and air into rotational energy through rotation and sufficiently mix and diffuse fuel gas and air.

(Means for Solving the Problems) In order to solve the above-mentioned problems and achieve the intended purpose, the gist of the present invention consists of a tank top lid that is airtightly integrated into the upper opening of the gas tank body. , a fitting recess with an upward opening integrally molded in the tank top lid; a through hole opened at the center of the bottom surface of the fitting recess and communicating into the gas tank body; and a through hole incorporated in the fitting recess and in the top end surface. a cylindrical lid-shaped nozzle spiral having a cylindrical lid shape, a bottomed cylindrical nozzle bottom stopper that is fitted into the nozzle spiral to form a valve chamber therein and has a valve opening on the bottom surface, and a spring or the like installed in the valve chamber. a gas ejection nozzle that is assembled into the nozzle and has an upper end protruding outward from the through hole of the nozzle spiral; a valve rubber that protrudes from the lower end of the gas ejection nozzle; A filter that allows a certain amount of gas to pass through during valve operation, an annular spacer that is fixed to the permeation filter by thermocompression bonding, ultrasonic welding, or impulse welding and is disposed within the fitting recess, and an upper edge of the annular spacer. an O-ring fitted onto the outer periphery of the nozzle bottom plug so as to join with the inner wall surface of the fitting recess to seal gas outflow from the side direction; A mixing tube communicating with the upper end and having an intake hole in the radial direction, a combustion tube connected to the upper part of the mixing tube, a discharge terminal fixed to the combustion tube via an insulator, and the mixing tube a diffuser plate disposed inside the boundary with the combustion tube and having a plurality of through holes penetrating in the vertical direction; a net-like body crowned on the upper surface of the diffuser plate; An internal combustion mechanism comprising swirl vanes each inclined in an arbitrary direction so that the air sucked in the mixing pipe and the fuel gas jetted from the gas jet nozzle are mixed in a swirl in the downstream combustion cylinder. In the internal combustion type gas lighter, the annular spacer has the transmission filter fixed to the lower edge thereof to close the lower opening, and the bottom surface of the nozzle bottom plug inserted from the upper opening is located below the spacer. The through hole of the fitting recess, which is assembled to the outer periphery of the nozzle bottom plug body and communicates with the gas tank and opens to the lower surface of the transmission filter, has a micropore diameter so as to protrude further downward than the end surface. In addition, the diffusion plate resides in an internal combustion type gas lighter, which is assembled so as to receive fuel gas ejected at high speed from a small hole in a nozzle plate provided at the tip of the gas ejection nozzle, and rotate. In the internal combustion type gas lighter, the through hole of the fitting recess has a micropore diameter of about 0.5 mm, and the small hole of the nozzle plate has an ultrafine diameter of about 50 microns.

(Function) In the internal combustion type gas lighter configured as described above, the transmission filter is fixed to the lower edge of the annular spacer to close the lower opening, and the bottom surface of the nozzle bottom plug is fitted from the upper opening. By assembling the annular spacer so that it protrudes further downward than the lower end surface of the annular spacer, the transmission filter is further tensed by the protrusion of the nozzle bottom plug, and the stator, mesh, etc. This allows the transmission filter to be prevented from bending when the gas pressure becomes higher than necessary, without adding another member.

In addition, by making the through hole of the fitting recess that communicates with the gas tank and opens on the lower surface of the transmission filter with a micropore diameter (preferably a micropore diameter of 0.5 mm), the LPG liquid level in the gas tank The outflow amount of vaporized gas can be controlled in advance, and the adverse effect on membrane properties due to excessive wetting of the permeation filter by liquefied gas, which occurs when the gas lighter is swung or turned upside down, can be prevented. becomes.

Moreover, the amount of so-called gas accumulation, which occurs when the liquefied gas in the gas tank accumulates in the through holes and on the bottom surface of the filter due to surface tension, is suppressed to a minimum, and the heat of vaporization is sufficiently and smoothly supplied without running out. It will be done.

Furthermore, by assembling the diffusion plate so as to rotate in response to the fuel gas jetted out at high speed from the small hole of the nozzle plate provided at the tip of the gas jetting nozzle, the fuel gas jetted toward the diffusion plate is assembled. Not only is the gas and air turned into a vortex by the action of the vortex blades installed on the diffuser plate, but the diffuser plate itself also rotates, so the kinetic energy of the gas ejected at high speed is absorbed by the rotation of the diffuser plate. The fuel gas and air are sufficiently mixed and diffused to convert into energy.

(Example) Next, an example of implementation of the present invention will be described with reference to the drawings.

A in the figure is an internal combustion type gas lighter according to the present invention, and this internal combustion type gas lighter A has a tank top lid 2 attached to an upper opening in a gas tank 1 filled with liquefied gas (LPG) by ultrasonic welding or the like.

This gas ejection nozzle 3g has a perforation 3i that communicates with the gas ejection path 3h opened in the radial direction of the outer peripheral surface, and a valve rubber 3j protruding from the lower end that is fitted to seal the lower opening of the gas ejection path 3h. By moving the distal end neck of the gas ejection nozzle 3g in the withdrawal direction, a valve port 3l formed in the bottom surface of the nozzle bottom plug 3c is opened and closed by the lower end surface of the valve rubber 3j. Further, an O-ring 3k is fitted to the lower end outer circumferential surface of the nozzle bottom plug 3c via an annular groove (not shown), and an annular spacer 5 to be described later.
It sits on the upper edge of the.

On the other hand, on the upper surface of the through hole 2b communicating with the gas tank 1, a membrane filter 4 is arranged to allow a certain amount of gas to pass through when the valve is opened. This membrane filter 4 is fixed in advance to the end face of an annular spacer 5 made of a synthetic resin material by thermocompression bonding, ultrasonic welding, or impulse welding, and the annular spacer 5 is press-fitted into the fitting recess 2a. It is fixed by In addition, by laminating a polypropylene nonwoven fabric 6 with a thickness of 75 microns on the upper surface of the membrane filter 4, a constant gas flow rate is ensured, and
A stable flame length can be obtained without being affected by gas pressure fluctuations.

At that time, the material of the membrane filter 4 is, for example, a maximum pore diameter of 0.4 x 0.04 microns,
Preferably, a microporous film made of polypropylene with a porosity of 45% and a thickness of 25 microns is used.

Further, as shown in FIG. 2, the membrane filter 4 is fixed to the lower edge of the annular spacer 5 to close the lower opening, and the bottom surface of the nozzle bottom plug 3c fitted from the upper opening is The annular spacer 5 is attached to the outer periphery of the nozzle bottom plug 3c so as to protrude further downward than the lower end surface of the spacer 5.

Furthermore, the through hole 2b formed in the fitting recess 2a, which communicates with the gas tank 1 and opens on the lower surface of the membrane filter 4, has a diameter of 0.3 to 2.1 mm, preferably 0.5 mm. and
In addition, the O-ring 3k is joined to the upper edge of the annular spacer 5 and the inner wall surface of the fitting recess 2a, thereby sealing the outflow of gas from the side direction.

On the other hand, the open end of an operating lever 3n supported to be able to swing up and down is engaged with the neck of the gas jet nozzle 3g that projects outward from the opening 3a of the nozzle spiral 3b. The neck of the gas ejection nozzle 3g is moved in the drawing direction by lifting the lever 3n, and the lower end surface of the valve rubber 3j is separated from the upper surface of the valve port 3l, opening the valve and starting to eject gas. It is attached.

Furthermore, at the spout of this gas jet nozzle 3g,
A nozzle plate 3p having a hole 3o with a diameter of about 50 microns in the center is sealed, and an internal combustion mechanism 7 is communicated with the upper part of the nozzle plate 3p.

As shown in FIG. 3, the internal combustion mechanism 7 includes a mixing pipe 7b communicating with the upper end of the gas jet nozzle 3g and having an intake hole 7a in the radial direction, and a combustion tube connected to the upper part of the mixing pipe 7b. 7c, and a discharge terminal 7 fixed to the inner surface of the combustion tube 7c via an insulator 7d.
e, a diffusion plate 7f disposed at the boundary between the mixing tube 7b and the combustion tube 7c, and a net-like body 7g such as a wire mesh covered with the upper surface of the diffusion plate 7f.

Further, as shown in FIG. 5, the diffusion plate 7f has a plurality of through holes 71f, 71f, . . . passing through in the vertical direction.
It is a light and thin disc that has ..., and each through hole 71f, 7
A plurality of swirl vanes 72f, 72f, . . . each inclined in an arbitrary direction are disposed inside 1f.

These swirl vanes 72f, 72f... are the nozzle plate 3 provided at the tip of the gas jet nozzle 3g.
The entire diffuser plate 7f is twisted and tilted in one direction so that when it receives fuel gas ejected at high speed from the small hole 3o of P, the diffuser plate 7f itself is rotated by the wind pressure, and the swirl vane 72f is on the lower side. It is loosely fitted into the combustion tube 7c in this state. Note that 8 in the figure is a lead wire (+).

In the internal combustion type gas lighter A of the present invention constructed as described above, gas vaporized at the LPG liquid level in the gas tank flows in through the through hole 2b opened at the center of the bottom of the fitting recess 2a when the valve is opened. The gas that has passed through the membrane filter 4 and then the nonwoven fabric 6 passes through the valve port 3 opened at the bottom of the nozzle bottom stopper 3c.

Then, the gas and air ejected toward the diffusion plate 7f flow into the combustion tube 7c while creating a vortex due to the action of the swirl vanes 72f, 72f of the diffusion plate 7f. Spout nozzle 3
Small hole 3o of nozzle plate 3p provided at the tip of g
The diffusion plate 7f receives the fuel gas ejected at high speed from the
is assembled to rotate within the combustion tube 7c, the kinetic energy of the gas ejected at high speed is converted into rotational energy by the rotation of the diffusion plate 7f, and the fuel gas and air are sufficiently mixed and diffused. It is something.

Further, the annular spacer 5 has the membrane filter 4 fixed to its lower edge to close the lower opening, and the bottom surface of the nozzle bottom plug 3c fitted from the upper opening is lower than the lower end surface of the spacer 5. Since the membrane filter 4 is assembled to the outer periphery of the nozzle bottom plug 3c so as to protrude further downward, the membrane filter 4 is further tensed by the protrusion of the nozzle bottom plug 3c, and the stator It is possible to suppress the deflection of the membrane filter 4 when the gas pressure becomes higher than necessary without adding a separate member such as a mesh or a mesh body, and it communicates with the gas tank 1 and is open to the lower surface of the membrane filter 4. The through hole 2b of the fitting recess is made with a fine hole diameter (preferably a fine hole diameter of 0.5 mm in diameter).
By doing so, the amount of gas vaporized at the LPG liquid level in the gas tank is controlled in advance, and the filter is prevented from overflowing due to liquefied gas, which occurs when the gas lighter is rocked or turned upside down. It is also possible to prevent adverse effects on film properties due to excessive wetting.

Moreover, the amount of so-called gas accumulation, which occurs when the liquefied gas in the gas tank 1 accumulates in the through hole 2b and on the lower surface of the filter 4 due to surface tension, is suppressed to a minimum, and the heat of vaporization is also sufficient without running out. Supplied smoothly.

(Effect of the invention) The present invention is constructed as described above, and the annular spacer has the transmission filter fixed to the lower edge thereof to close the lower opening, and the bottom surface of the nozzle bottom plug inserted from the upper opening is By assembling the spacer around the outer periphery of the nozzle bottom plug so as to protrude further downward than the lower end surface of the spacer, the transmission filter is further tightened by the protrusion of the nozzle bottom plug, so that it is fixed. It is possible to suppress the deflection of the transmission filter when the gas pressure becomes higher than necessary without adding a separate member such as a shield or a mesh body. The through hole of the fitting recess is made with a fine hole diameter (preferably 0.5 mm in diameter).
By making the micropore diameter of
The outflow amount of gas vaporized at the LPG liquid level is controlled in advance, and the negative effect on membrane properties due to excessive wetting of the permeation filter by liquefied gas, which occurs when the gas lighter is rocked or inverted, is prevented. In addition, the liquefied gas in the gas tank accumulates in the through holes and on the bottom surface of the filter due to surface tension, and a large amount of heat is required to vaporize the accumulated liquefied gas. This eliminates the drawbacks of conventional methods, such as the gas not being vaporized due to insufficient heat, resulting in unstable flames.
This has the effect of suppressing the amount of gas trapped to a minimum and supplying heat of vaporization without running out.

Moreover, there is no need to install an annular spacer inside the gas tank like in the past, and it can be easily installed into the fitting recess from the top, so it goes without saying that the spacer can be installed easily, and the airtightness of the valve is improved. will not be damaged.

In addition, the diffusion plate equipped with swirl vanes is assembled so as to rotate when receiving the fuel gas jetted out at high speed from the small hole of the nozzle plate provided at the tip of the gas jetting nozzle. The vortex blades installed on the diffuser plate not only turn the gas and air ejected into a vortex state, but also rotate the diffuser plate itself, so the kinetic energy of the gas ejected at high speed is transferred to the diffuser plate. The rotation of the fuel gas and air can be converted into rotational energy to sufficiently mix and diffuse the fuel gas and air.
