Description

Combustion apparatus

The present invention relates to a kind of burner of the ignitable fuel that burns, such as a gas lighter, and it is equipped with the flow rate regulating device that is used for regulating the ignitable fuel flow rate, and more specifically, relate to a kind of burner, can improve its availability and ability to work, and guarantee stable burning.

The burner of burning ignitable fuel comprises such as lighter, various types of igniter, portable gas range and light fixture etc.In the middle of them, the lighter that a kind of flow rate regulating device of the flow rate that the ignitable fuel that is used for regulating injection is housed is arranged, this class lighter such as be disclosed in patent announcement Nos.50613/1988 that Japan examined, 21092/1988 and the utility model notification number Nos.18852/1991 and 35969/1991 that examined of Japan in.Lighter among the patent announcement No.21092/1988 that Japan has examined is shown among Figure 12.This lighter has a lighter body 101, and this body 101 has a cylindrical shape capsule portion 103 that is formed in the lighter body 101.Inside round the lighter body 101 of capsule portion 103 outer surfaces plays a part fuel bunker 105.This fuel bunker 105 is filled with ignitable fuel.

One valve body 107 is firmly held in the capsule portion 103 by an articulated structure.One valve burner 109 is connected in these valve body 107 inboards and can moves up by upper and lower in the drawings.One liner 111 is positioned at the bottom of this valve burner 109.Valve burner 109 and liner 111 generally are subjected to the downward pressure of a helical spring 113, make liner 111 compress valve seat 115.Valve seat 115 is formed at the top of a cylindrical parts 117.One passage 119 forms in the core of this cylindrical parts 117, and its lower end forms gap 121.

One supporting member 123 be positioned at cylindrical parts 117 below, decompressor 125 then places between cylindrical parts 117 and the supporting member 123.This decompressor 125 is so-called flow rate regulating device, and it comprises that half perforated membrane 125a and one closely places the perforated membrane 125b of this half perforated membrane 125a.

The hole radius of half perforated membrane 125a is 20 to 500 dusts, and it is used such as ductile polyolefin, particularly polypropylene or polyethylene and makes.

Ignitable fuel in the fuel bunker 105 flows in gap 121 and the passage 119, simultaneously decompression under the flow rate control of this decompressor 125.When valve burner 109 moved up against the spring force of helical spring 113, the hole 109a that ignitable fuel is flowed through in the valve burner 109 flowed in the valve burner 109, and from valve burner 109 terminal ejaculations.

Except the lighter shown in Figure 12, also have a kind of device of the flow rate by film-type flow rate regulating device control ignitable fuel to be disclosed among the patent announcement No.19448/1992 that has examined such as Japan, wherein the film-type flow rate regulating device has utilized ceramic porosity characteristic.

Above-mentioned traditional structure has following shortcoming.With regard to regard to this class flow rate regulating device shown in Figure 12, (be about 25um because the thickness of the filter of decompressor 125 or each film 125a and 125b is very little, even on film, be bonded with the adhesive-bonded fabric 100um that also only has an appointment), therefore this filter is wanted extreme care when using it.And the edge part of effective area part is clipped in up and down between the parts (being cylindrical parts 117 and the supporting member 123 in the structure shown in Figure 12), or edge part is fixed and is sealed on the resin piece by hot melt or similar approach in some cases.Even connect filter in the above described manner, flow rate regulating device or filter itself is very thin, so mechanical strength and calorific intensity are all lower.Therefore flow rate regulating device may be because of because of carelessness in assembling or when moving back and forth, or As time goes on may be damaged.In other words, because decompressor 125 is single film 125a and 125b, because of being difficult to move back and forth decompressor, and very difficultly satisfy safety requirements constantly.

Except this problem, traditional lighter lacks the flammability of safety.In general, the diameter of the effective area of used gas lighter is very little during igniting, about 2 millimeters.Because the through-hole diameter in the film 125a shown in Figure 12 is little of about 20 to 500 dusts, the flow rate of gas be along with the change of through-hole diameter may alter a great deal, thereby makes the also change of flame size of generation.Just, in the very narrow effective range of 2 millimeters of diameters, when through-hole diameter changes in the scope of 20 to 500 dusts, flow rate by through hole and and then the correspondingly change of flame that produced.

The second method that adopts ceramic porous characteristic to regulate flow rate needs the very little hole of handled, and as the structure shown in Figure 12, the change of specific gas flow rate is also very big.Adopting used thickness is 2 millimeters, diameter when being 3 millimeters ceramic filter, and liquid often rests on ceramic filter inside, and like this, when opening of valves, it is its gas of 200 times that liquid fuel is transformed into volume.Therefore, burned flame is very big, and this is a danger close to the user.

The solution of the problems referred to above has disclosed among the utility model publication number Nos.151666/1979,162762/1980,72069/1981,66264/1983,61659/1993 and 117635/1994 of Japanese unexamined.In traditional device, Japan does not retrieve the device that is disclosed among the utility model publication number Nos.151666/1979,162762/1980,72069/1981,66264/1983 and 61659/1993 and is designed to have one by the lampwick spare that constitutes such as natural fibers such as cotton lines that scribbles airtight coating between fuel bath part and combustion parts, and effluent air quantity is controlled in some levels.The scheme that discloses among the Japanese unexamined utility model publication number No.117635/1994 is such, the regulating part that promptly has a lampwick spare that scribbles airtight coating that is made of several soft copper cash between fuel bunker portion and burning portion is to guarantee stable gas flow.

Those devices that in the utility model publication number Nos.151666/1979,162762/1980,72069/1981,66264/1983 and 61659/1993 of Japanese unexamined, disclose, wick spare adopts the cotton line of the natural fiber formation that alters a great deal, and therefore is difficult to provide stable specific gas flow rate always.Therefore the device that discloses among the utility model publication number No.117635/1994 of Japanese unexamined can be regulated big gas flow, is not suitable for being used for regulating the specific gas flow rate such as disposable gas lighter.That is,, and do not have miscellaneous part to regulate flow, then can flow out the liquid gas that gasifies without suitably in a large number if this traditional device directly is used as the flow rate regulating device of disposable gas lighter.

Therefore, an object of the present invention is to provide a kind of burner that flow rate regulating device is housed, it can guarantee smooth combustion, can satisfy safety requirements for a long time again simultaneously.

For achieving the above object, but burner of the present invention comprises a valve by an On/Off sprays the nozzle of the ignitable fuel that is positioned at a fuel reservoir; Be positioned at the valve upstream end and the flow rate control device of a lampwick spare is arranged, lampwick spare uses the line that is made of many fibers to make or make with many filaments, and one around the impenetrable parts of the fuel of lampwick spare, thereby, ignitable fuel in fuel reservoir utilizes the capillarity of line or filament or utilizes between the fiber of line or the passage that acts as a fuel of the gap between the filament is supplied with, and the fiber of line is continuous elongated fibers and one of synthetic fibers, metallic fiber, carbon fiber, glass fibre and hollow line.

Referring now to Fig. 1 to Fig. 4 first preferred embodiment of the present invention is described.In this embodiment, the present invention is used to adopt the gas lighter of ignitable fuel.Gas lighter has lighter body 1, at lighter body 1 internal shaping one capsule portion 3 is arranged.Played the effect of the fuel bunker 5 of storage ignitable fuel round the inside of the lighter body 1 of capsule portion 3 outer surfaces.The ignitable fuel that uses is a liquid gasoline gas, and it forms (commerce propane that 90% commerce use butane and 10%) with butane and commerce with propane by commerce basically.

Except liquid gasoline gas, also can adopt other ignitable fuels, such as pure liquid fuel and alcohol liquid fuel.One nozzle housing 7 is connected in capsule portion 3, and nozzle housing 7 is columniform basically, is formed with threaded portion 7a on its outer surface.There are an internal thread part 3a and threaded portion 7a interlock in capsule portion 3.Utilize the interlock of threaded portion 7a and internal thread part 3a, nozzle housing 7 just is fixed on capsule portion 3.One nozzle group valve seat is positioned at nozzle housing 7.

One nozzle 11 passes nozzle housing 7 and is positioned at it, and can move up by upper and lower in the drawings.Middle body at nozzle 11 is formed with an air flue 11a and an air admission hole 11b.One valve module (such as rubber parts) 13 is connected to the lower end of nozzle 11.More particularly, the shape of valve module 13 resembles a jut 13b from the core projection of dish 13a.Jut 13b inserts the air flue 11a of nozzle 11 from the lower end.One valve seat 9a forms in the middle body of nozzle valve seat 9, and 13 of valve modules are on valve seat 9a.

Nozzle 11 and valve module 13 are located on the valve seat 9a valve module 13 usually because of the effect of a helical spring 15 is subjected to downward power.When the actuator shown in the with dashed lines 17 among Fig. 1 rotates in Fig. 1 along clockwise direction so that nozzle 11 when moving up against the active force of helical spring 15, because the effect of gas pressure, valve module 13 lifts and opens.That is, remove on the valve seat 9a of valve module 13, flow into by the air flue 9b of nozzle valve seat 9 to allow gas, air admission hole 11b and air flue 11a that therefore gas pass through nozzle 11 penetrate.

There is a fuel flow rate control device 19 at capsule portion 3 places under nozzle valve seat 9.This fuel flow rate control device 19 has the Elastic Cylindrical part 19a of part thoroughly that acts as a fuel, and also has a line 19b who inserts elastic component 19a central portion.It is that the 70 butyronitrile butadiene rubber (NBR) of spending are made that elastic component 19a uses such as intensity.As shown in Figure 2, elastic component 19a length L in the axial direction is 2.5 millimeters.Axial middle body at elastic component 19a is drilled with a hole 21, and its interpolation lambda line 19b as shown in Figure 2, can adopt such as an eedle and get out this hole 21, and the diameter D1 in hole 21 is slightly less than the outer diameter D 2 of line 19b.Do not wish the outer diameter D 2 of aperture D1, because this can form the gap that gas is leaked betwixt greater than line 19b.

Without eedle boring, may form the crack.Line 19b has a burst shape structure, and a burst shape structure has many strands synthetic fibers (see figure 4) such as polyester fiber 22 and so on together.

Except polyester fiber, also adoptable other synthetic fibers are such as vinylidene chloride, polypropylene and nylon.

Every fiber 22 is the long fibres that are of a size of 1.3 Denier (1 Denier equals/9000 meters of 1 grams).Total about 630 fibers 22.(Fig. 4 illustration strand section, for the sake of simplicity, the quantity that the number of shown fiber 22 is mentioned among the embodiment therewith is unequal).The line 19b of this structure inserts in the hole 21 of elastic component 19a and is in as shown in Figure 4 state.Gas flows through the gap between the fiber strand, and makes its flow rate adjusted, as shown in Figure 4.

According to experiment, be under 23 ℃ the situation recording temperature, about 30 millimeters of combustion flame height.

As shown in Figure 1, lampwick 23 is positioned at the fuel flow rate control device 19 times, and like this, the ignitable fuel in the fuel bunker 5 upwards picks up by this lampwick 23, and its flow rate is adjusted by the fuel flow rate control device 19 with said structure.

In Fig. 1,25 refer to a rotary file, and 27 refer to be positioned at the guide on rotary file 25 both sides, and 29 refer to a calcium carbide.

The action of the gas lighter with said structure is discussed now.At first, user's thumb places on a pair of guide 25, and guide 25 is rotated along the clockwise direction among Fig. 1, thereby actuator 17 is also then rotated along clockwise direction.As a result, nozzle 11 is raised against the power of helical spring 15.Therefore, because the gas pressure that acts on from below, valve module 13 upwards lifts, thereby is unlocked.Gas flows through air flue 9b, and enters air flue 11a through the air admission hole 11b of nozzle 11.Then, gas penetrates from the end of nozzle 11.When guide 25 rotated, file 25 rotated thereupon, makes calcium carbide 29 send spark.Spark ignition from the gas of nozzle 11 ejection.In this continuous action, the ignitable fuel in the fuel oil storage tank 5 flows to valve, and flow rate is regulated by fuel flow rate control device 19.

This embodiment has following advantage, and at first, fuel flow rate control device 19 has certain thickness, and does not resemble traditional film-type device, and therefore, this control device 19 is adding man-hour or operating easily when assembling gas lighter.More particularly, owing to the outside of fuel flow rate control device 19, be that elastic component 19a compares with the conventional thin membranous type and has enough thickness, therefore when operating control device 19, can catch elastic component 19a.Therefore, during at Working control device 19 or at the assembling gas lighter, be easy to operating control device 19.Because elastic component 19a has been arranged, improved the mechanical strength and the calorific intensity of fuel flow rate control device 19, it is stable that control device 19 is acted in long time.And fuel flow rate control device 19 can be because of not careless or along with the time changes and damages during lighter in processing or assembling.Structure (for example number of its type, fiber and length or the like) by changing line 19b on demand can obtain suitable flow rate adjustment characteristic.This helps eliminating the change of line 19b, thereby improves stable combustibility.And, different with prior art, do not use natural fiber, also eliminate the change on performance, and guaranteed the flow rate control of high accuracy.

Explain second embodiment referring now to Fig. 5.Although in first embodiment, line 19b has one polyester fiber such as synthetic fibers, as shown in Figure 5, also can adopt the vinylidene chloride hollow line of synthetic fibers.Such as, eight hollow lines 24 are twisted into thigh, every hollow line is made up of the long fibre of 50 Denier.In the case, confirming by experiment, is that the combustion flame height is about 30 millimeters under 23 ℃ the situation recording room temperature.The line 19b that is made up of hollow line 24 can immerse fuel bunker 5, and it is up to make ignitable fuel pass through the hollow space 24a of every hollow line 24, thus the adjustments of gas flow rate.In the case, line 19b is used as lampwick 23 as shown in fig. 1.

Explain the 3rd embodiment referring now to Fig. 4.Though the line 19b that adopts synthetic fibers to form in first and second embodiment, in this embodiment, line 19b is made of carbon fiber.More particularly, about 100 lines 22 are twisted into thigh, and every line 22 is by the diameter of the about 15um(fiber 22 of size) elongated fibers form.Confirmed already, measure about 25 millimeters of the combustion flame height of room temperature when being 23 ℃.

Below with reference to Fig. 4 the 4th embodiment is described.In this embodiment, line 19b is made of metallic fiber (being the copper fiber among this embodiment).More particularly, about 12 lines are twisted into thigh, and every line is made of the elongated fibers of the about 60um of size.Confirmed already that the combustion flame height when recording room temperature and be 23 ℃ was about 35 millimeters.

Explanation the 5th embodiment referring now to Fig. 6.This embodiment has the structure among Fig. 1, but does not have lampwick 23.Such as, when using liquid gasoline gas as ignitable fuel, lampwick 23 does not just need, and therefore can dispense as shown in Figure 6.

Referring now to Fig. 7 and Fig. 8 the 6th embodiment is described.In first to the 5th embodiment, line 19b is contained in the through hole 21 as the elastic component 19a of supporting member, thereby has constituted fuel flow rate control device 19.Yet in the 6th embodiment, supporting member 19a and line 19b make one in advance.More particularly, as shown in Figure 8, thermoplastic resin, thermosetting resin, rubber and so on can be from extruding (although do not draw among the figure, having adopted compression moulding machine and predetermined model when compression moulding) round the extrusion mode of line 19b, thereby made product as shown in phantom in Figure 8.This product is cut into Len req, to make fuel flow rate control device 19() by shown in the solid line among Fig. 8.In the case, the not saturating part 19a of fuel needs not be and uses elastic component.In order later on line 19b to be passed the saturating part 19a of fuel, saturating part 19a should be an elastic component in the last example, with online 8 and the saturating part 19b of fuel between keep air-locked sealing.But, when the saturating part 19b of line 19b and fuel is integrally formed, do not need to consider air-locked sealing.Therefore the not saturating part 19b of fuel needs not be an elastic component.This structure also can produce aforesaid same advantage.

Referring now to Fig. 9 the seventh embodiment of the present invention is described.In this embodiment, the line 19b of fuel flow rate control device 19 has different structures.The wire 31 of single (or more) places in the middle body, and the fiber of selecting from synthetic fibers, regenerated fiber, metallic fiber, carbon fiber and glass fibre 33 is round wire 31.Line 19b with this structure has same advantage.

This structure is more specifically described below.Wire 31 is the soft copper silks that are coated with such as tin, and external diameter is 0.18 millimeter (180um), and length is 3.5 millimeters.This wire 31 imposes on heat the liquid gas that flows along this wire 31 and makes this gas evaporation, thereby has guaranteed sufficient gasification.That is, the latent heat that has of wire 31 has passed to liquid gas.Line 19b has one totally 1600 glass fibres.More particularly, the glass fibre sheave of 400 6um or be twisted into thigh, and four such strand be twisted into thigh again along the direction opposite with above-mentioned per share strand.

Introduce step by step below and made.At first, the glass fibre of 400 6um is twisted into Dan Shu.Four such bundles are along being twisted into thigh around wire 31 in the opposite direction with the per share strand side that is twisted into single fibre bundle then.But the fibre bundle that is produced places the geat central authorities of extrusion molded machine in the mode of feeding, inject the polyethylene that melts then, thereby all these is integral by extrusion molded mechanism.

In the case, the passage of liquid fuel process mainly is that along the gap between line 19b and the wire 31, and the effect of air flue can be played in the gap (being the gap between the individual glass fibers) in the line 19b itself, but less.When extrusion molded, polyvinyl resin enters between line 19b and the supporting member 19a, is shielding this gap, thereby has only gap seldom to be used as air flue.Gap between online 19b and the wire 31 can be used as the main thoroughfare, because make the required heat of liquid gas gasification can impose on the gas of advancing along wire 31.

Explain the eighth embodiment of the present invention referring now to Figure 10.In this embodiment, the structure of the line 19b of fuel flow rate control device 19 is also through revising.Single (or many) wire places in the middle body, and hollow line 33 is around this wire 31.Line 19 with this structure can have same advantage.

Explain the ninth embodiment of the present invention referring now to Figure 11.This embodiment is designed to regulate flame height on demand.Outer surface part in nozzle housing 7 has internal thread 7a, is formed with internal thread 3a in the capsule portion 3 of lighter body 1.By the interlock of internal thread 7a and internal thread 3a, nozzle housing 7 is connected to capsule portion 3.Identical among this part structure and first embodiment (being shown in Fig. 1).One rotating drive part 41 is connected to the top of nozzle housing 7.Such as, when the user rotated this rotating drive part 41 with thumb along suitable direction, nozzle housing 7 was rotated, thereby nozzle housing 7 and nozzle valve seat 9 are lifted.The moving upward of nozzle housing 7 and nozzle valve seat 9 regulated the gap between nozzle valve seat 9 and the fuel flow rate control device 19.One porous member 43 is arranged between nozzle valve seat 9 and fuel flow rate control device 19.This porous member 43 can be made of urethane foam.

Utilize said structure, when the user need increase flame height, can rotate rotating drive part 41 along a direction.This moves upward nozzle housing 7, has increased the gap between nozzle valve seat 9 and fuel flow rate control device 11.Porous member 43 correspondingly expands, thereby the air bag density in the porous member 43 is increased.Therefore, the quantity of the ignitable fuel of process increases therefrom, and flame height is increased.On the other hand, in order to reduce flame height, the user should rotate this rotating drive part 41 in opposite direction.This moves downward nozzle housing 7, thereby makes the gap turn narrow between nozzle valve seat 9 and the fuel flow rate control device 11.Therefore porous member 43 is compressed, and the air bag density in the porous member 43 is reduced.Therefore, by ignitable fuel quantity minimizing there, thereby reduced flame height.

Porous member 43 can change the flow rate of ignitable fuel.Thereby, being set in a predetermined value by quantity with porous member 43, flame height can be limited to assigned altitute.And porous member 43 can be regulated flame height in required height when suitably expanding or compressing.

The present invention is not limited to the foregoing description, at first, although gas lighter illustrates as the example of ignitable fuel burner in the description of the foregoing description, the present invention also can be applied to all kinds of igniters outside gas lighter, portable gas range, the light fixture etc.The fiber that constitutes the line 19b of fuel flow rate control device 19 can be the above-mentioned regenerated fiber, carbon fiber or the glass fibre that are coated with gold through surface-treated glass fibre or surface outside all kinds of.Any two kinds of fibers in synthetic fibers, metallic fiber, carbon fiber and glass fibre can interosculate.Perhaps, general fibre can combine with a hollow line.Although in the above-described embodiments, line has a burst shape structure, and line is not limited to this particular type, also can be made of the line that does not add strand of bunchy.The particular value that provides in each embodiment is the usefulness of explanation for example just, the invention is not restricted to these particular values.
