Disposable fuel burner

The present invention relates to disposable fuel burner and employed fuel and wick, this oil burner is generally used for heating bain-marie or other such as the situation of food heating, and low-level lighting perhaps is provided.

Various types of disposable fuel burners have been introduced in the front.Usually, existing disposable fuel burner all comprises an a kind of liquid fuel or gelinite fuel in the container that is contained in, and part is immersed in the wick in the fuel, and a wick bearing, and the part of wick is stretched out by bearing.The fire proofing that some existing oil burner also has one deck porous contacts with the exposed part of wick.In this class oil burner, because capillarity, fuel infiltrates in the porous layer by wick, and these fuel can be lighted.Usually, the wick bearing of former disposable fuel burner is a metal plate that has a wick by the hole, also has one or two less opening above it, allows air to enter the grease chamber.In addition, also some previous disposable fuel burner is thick short jar shape, and the core that the top of jar has a protuberance is used to support wick, a spiral cover can also be installed to prevent that fuel flows out in transportation from oil burner on the core.This oil burner has a kind of many parts structure usually.

Existing disposable liquid body fuel stove and accessory has a series of defectives.The defective of existing oil burner comprises:

(a) some stove, particularly those are equipped with the stove of gelinite fuel, can become awfully hot in combustion process and/or after using, and therefore do not take suitable safeguard procedures just can't pick up stove to skin;

(b), just make the outdoor serviceability variation of this disposable fuel burner because flame can be unstable in wind;

(c) have the oil burner of liquid fuel, or the gelinite oil burner of those heating in use, when by accidental being knocked over, fuel overflows from stove easily;

(d) in some oil burner, flame height, just the flame density refractory maybe can't be regulated to regulate;

(e) some stove if in use be subjected to bump from the side, will bring security incident;

(f) for some stove, if, just be difficult to rekindle because some are former thereby extinguish;

(g) some stove is relatively complicated, and/or manufacturing cost is higher;

(h) have the stove of gelinite fuel, when not using, and sometimes in use, can have the smell of a kind of ethanol or methyl alcohol, this is unallowed under food product environment.

The disposable fuel burner that is not all prior arts all has all described defectives, but has in these defectives one at least.

Therefore, just need improved disposable fuel burner.

Therefore one object of the present invention just is to have proposed a kind of improved disposable fuel burner.

A kind of disposable fuel burner that first kind of embodiment according to the present invention proposes, it comprises a container that part of fuel is housed at least, also has

The bottom of a sealing;

The sidewall of sealing;

The wick bearing, it is positioned at the top of fuel surface, and is connected across on the sidewall, has a depression at least a portion of wick bearing, and the bottom of depression has a wick supporting opening, and the wick bearing at least also has an air inlet opening;

An elongated and loose wick, the one end is immersed in the fuel, and the other end passes by wick bearing opening, and fuel can be in the exposed end burning of wick.

Usually, the disposable fuel burner among first kind of embodiment only has an air inlet opening.

In a kind of form of this embodiment, the air inlet opening is arranged in the depression of wick bearing, on the depression sidewall, perhaps on the bottom surface of depression.In the another kind of form of present embodiment, a kind of cup-shaped part is provided, and this part is between wick bearing and fuel, around the air inlet opening, between cup-shaped part and wick bearing, define an enclosure space, have an airport on the cup-shaped part.In this disposable fuel burner of first kind of embodiment, cup-shaped part can hold the fuel that flows out by airport, therefore can reduce or prevent that fuel from passing through the leakage in the air inlet hole on the wick bearing.Usually, the arrangement mode of the airport on the cup-shaped part is wanted to guarantee that the fuel that enters cup-shaped part can be back in the fuel container by airport.

In the another kind of form of present embodiment, disposable fuel burner has the valving with the air inlet relevant action, when disposable fuel burner is moved or is inverted with respect to the use location, valve parts can prevent that fuel from leaking by air inlet, and allows air to enter fuel container when disposable fuel burner is in the use location.

Valve parts can be any convenient means, and when disposable fuel burner was in the use, it allowed air to enter fuel container by the air inlet opening; And be in the transportation or toppled over or when being inverted, it can stop (preventing substantially usually) fuel to flow out by the air inlet opening when disposable fuel burner.Usually, in this form of first kind of embodiment, valving comprises the plastics of a flexibility or the film of metal, this film is encapsulated in beneath (just being arranged in the side of fuel container on the wick bearing) of wick bearing, this film or seal have one or more breach, when disposable fuel burner was in the use location, air can enter fuel chambers by air inlet openings and breach; And when disposable fuel burner was in dump position or is inverted, the fuel in the disposable fuel burner was just oppressed film and is closed tightly breach, and/or makes air inlet openings close by film.

For example, on the wick bearing, the cingens thin film center of seal zone is separated with the wick bearing, and covers on the air inlet openings with thin-film package at edge that can wound film.Have one or more slits on the central area.When disposable fuel burner was in use, air entered air inlet openings, and entered the inside of fuel chambers by the slit on the film.But such as when disposable fuel burner is inverted, the size in slit can guarantee to prevent that fuel from oozing out from fuel chambers.The quantity in slit generally is one or two, normally one.The slit is linear or V font normally, but also can be any possible shape.

In the another kind of form of valving, be used for film is installed on the perimeter seal on the above-mentioned wick bearing and have at least one breach, the breach on the seal provides one or more openings for air enters fuel chambers.In this form, there is not the slit on the film usually; That is to say that the breach on the seal just air enters the passage of fuel chambers inside from air inlet openings.In the valving of this form, when disposable fuel burner was in user mode, air can freely enter the inside of fuel chambers; If but for example, when disposable fuel burner was inverted, the pressure that acts in the disposable fuel burner on the film just was pressed on film on the wick bearing, thereby prevent that fuel from flowing out by breach on the seal and air inlet openings.Usually, on seal, has only a breach.

Usually, the position of film on the wick bearing should make the breach of air inlet openings away from perimeter seal, or the slit on the film, and this will decide on concrete situation.

If necessary, valving can comprise plural layers, the seal that is encapsulated on the wick bearing and/or repeatedly is enclosed in mutually each layer film together all has a breach, or all have a slit on each layer film, or slit and seal combine, and form air enters fuel chambers inside from air inlet openings passage.Usually, have the seal breach of two adjacent layer films, or under the situation in two adjacent layer film slits, should be good more between the position in breach or slit apart from far away more.

The film of valving can be any suitable shape, for example, and square, rectangle, circle, ellipse, hexagon or the like.Usually do rectangularity, square or circular.Film is thin polymer film normally, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyvinyl alcohol, wherein modal is polyethylene and polyvinyl chloride.Film can also adopt metal material, for example, and tin or aluminium.Film can adopt any method easily to be encapsulated on the wick bearing, comprises gluing or heat-sealing, and/or can adopt soft soldering, welding or soldering for metallic material film.Should understand that thin-film material and any adhesive that is used for it is enclosed on the wick bearing must be inert materials all, and can not be subjected to the influence of the fuel in the disposable fuel burner.

Disposable fuel burner can also comprise a top cover that has opening, and the wick bearing is between top cover and fuel, and the opening of wick bearing has the opening of a part facing to top cover at least.When having top cover, and/or be formed on depression on the wick bearing, just can keep off the rain for burned flame is windproof on stove wick exposed part.Usually, the top cover opening be located in wick bearing opening directly over, the same big with wick bearing opening at least, more common situation is greater than wick bearing opening.Common top cover opening is rounded, oval, square, rectangle, triangle, hexagon, octagon or pentagon, and modal is circular.With respect to the size of wick bearing opening, normally its 1 to 5 times of top cover opening, more commonly 1.5 of its size to 4 times, modal is its 2 to 3 times.Usually, the selection of the distance between the size of top cover opening and top cover and the wick bearing will guarantee to pull out or be pressed into by the bearing opening with the handgrip wick, and also will guarantee is simultaneously having under the condition of wind, for flame provides windproof protection.

In this form of the present invention, top cover can be used as a kind of retaining device, to preserve the fuel that may flow out by the air inlet openings of wick bearing, particularly when disposable fuel burner is in normal stand up position, air inlet openings is positioned under the situation of the part that wick bearing upper top cover covered.

Therefore, in second kind of embodiment, the present invention proposes a kind of disposable fuel burner, it comprises a container that a part of fuel is housed at least, also has

The bottom of a sealing;

The sidewall of sealing;

One is positioned at the fuel surface top, and has the first wick bearing of a wick bearing opening and at least one air inlet openings;

At least can partly preserve the fuel retaining device that flows out fuel from described air inlet openings; An elongated and loose wick, the one end is immersed in the fuel, and the other end stretches out by wick bearing opening, fuel can be lighted at the exposed end of wick.

The wick bearing that should be understood that this form among the present invention need not to have depression, and can be plane fully, or is the cima shape.Yet, a kind of plane wick bearing or to have the wick bearing of depression better.When the wick bearing is plane fully, or when having a depression, when in case disposable fuel burner returns to normal stand up position, the fuel (for example, causing that fuel flows out because disposable fuel burner is toppled over or is inverted) that is kept between fuel retaining device and the wick bearing can be easier to by the capillarity of wick be back in the fuel chambers.

The fuel retaining device is the top cover of a disposable fuel burner normally, and it has one and wick bearing opening opening opposing, and top cover is connected across on the sidewall of oil burner.For the purpose of convenient, the inner edge of this top cover opening can be bent downwardly, and that is to say towards the wick bearing.

For this disposable fuel burner, the disposable fuel burner that particularly has the wick bearing of general plane, in case advantage just is that this stove is when dump position or upside down position return to stand up position, the fuel that leaks between fuel retaining device and the wick bearing can not form oil sump around wick, wick can be rekindled easily.In addition, by pulling out or being pressed into, can adjust the height of wick easily up and down.When pulling out, the wick that stretches out on the wick bearing is partly extended; When being pressed into, wick can deposit in the space between fuel retaining device and the wick bearing, thereby reduces the height of wick effectively.In the disposable fuel burner of prior art,, just be difficult to or may do not reduce the height of wick usually from an opening tightly in case wick is pulled out.

In the another kind of form in the present embodiment, disposable fuel burner only has an air inlet openings, this air inlet openings is positioned on the wick upper surface of support by one or the lid of its top seals, lid has an opening at least, so that the permission air enters into the space between lid and the wick bearing.Usually, the air inlet of this form is arranged in the depression of wick bearing, and shape at least a portion of lid stretches in depression.More typical situation is that the depression circumference that inwardly stretches on the lid forms an antelabium, and is tangent with the depression circumference of wick bearing.For example, the inward flange of antelabium bends towards the surface of depression, thereby forms a slight gap around the inside antelabium that stretches of bearing depression can to do one on the lid, usually about 1mm, and this gap provides opening for entering of air.Air inlet openings on the wick bearing in the depression is positioned on the surface of depression, between depression circumference, wick bearing depression surface and the antelabium of lid.

In addition, perhaps alternatively, a kind of disposable fuel burner among second kind of embodiment can have a kind of valving that is used for air inlet openings, and the valving is here touched upon in first kind of embodiment.

Usually, in such an embodiment, roughly be the plane around the zone beyond the depression on the wick bearing, depression is exactly a depression that forms in the zone of the general plane on the wick bearing.Usually, the zone of general planar comprises the edge from the depression peripheral region to the wick bearing, and can comprise one or more shallow rib, and these shallow ribs are looped around around the depression usually.Have these shallow ribs and can strengthen the face shaping of disposable fuel burner.

The wick bearing can be connected on a certain position of fuel retaining device, or expands on the sidewall of disposable fuel burner always, and perhaps both have both at the same time.Connection can be adopted any mode easily, and for example, bonding, welding, soft soldering, eyelet, crimping engage or the like.In a kind of disposable fuel burner according to the present invention, the outward flange of the outward flange of wick bearing and fuel retaining device all spinning is combined on the sidewall top of disposable fuel burner.

In a kind of disposable fuel burner according to first kind or second kind embodiment, stove also has sealing device, so that prevent that fuel spills in transportation from stove.Like this, when the sealing device installation in position, just can prevent effectively disposable fuel burner be inverted or the situation of toppling under, fuel leaks from disposable fuel burner.

For example, sealing device can be a removable cap, seals on the closed side wall of the wick bearing that is installed in disposable fuel burner; If stove has top cover, then sealing is installed on the top cover of disposable fuel burner.In one form, removable cap can make reducible, so that extinguish the flame of burnt fuel in wick under the situation of needs.Removable cap also can make the form that can not reset.For example, detachable lid can depended on pressure be installed in container or the sidewall of the antelabium that inwardly stretches in and on the sidewall, just as traditional coating can lid or other surface finishing method.Also can use a traditional device for releasing closures that lid is taken out from the container of disposable fuel burner.Can also make removable cap have the helix part, unscrew lid, can pull down lid from the container of disposable fuel burner by helix from pairing container side wall.Can also detachable lid be sealed on the sidewall of disposable fuel burner by the easily broken seal of a kind of annular, lid can be opened when being subjected to pulling force.Usually, detachable lid can be bonded on the tin can main body.For simplicity, can have a draw ring on the detachable lid, so that dismounting.The salable lid of other type is conspicuous for the those skilled in the art of correlative technology field.

Sealing device can also be a kind of Adhesive Label that peels off, and label covers on the depression of wick bearing, and when disposable fuel burner had top cover, then label covered on the top cover of disposable fuel burner.The material of label is generally grease proofing material, and top glue is unaffected when touching fuel.For simplicity, Adhesive Label is made by flexiplast usually, for example polyethylene, polypropylene, polyvinyl chloride or materials similar, and on the part of one side at least, have and can peel off adhesive.Usually, Adhesive Label is that the PVC of a kind of plasticised polyvinyl chloride (PVC) or metal is the film of the metal of matrix, made of paper, fiber etc.Adhesive is generally acrylic emulsion glue, can paste fixing again.Usually, Adhesive Label has a part for grasping, so that pull down sealing device from disposable fuel burner.Should understand, when sealing device not only covers wick bearing opening but also covers the air inlet of wick bearing, use this sealing device the most effective.

Sealing device can also be one that can open and closely be tucked in the depression of wick bearing, or stopper or plug in the top cover opening of disposable fuel burner.Usually in this case, sealing device is a kind of elastoplast stopper that its size can seal depression surface or opening, thus disposable fuel burner be inverted or the situation of toppling under, plastic stopper can prevent that fuel from leaking from disposable fuel burner.When depression has air inlet, adopt that this to be the sealing device that stopper shape can seal in the depression that is installed in the wick bearing the most effective.

In the disposable fuel burner of some form of the present invention, the wick that stretches out from wick bearing opening may be pressed onto the stopper that inserts depression or opening, also stopper may be held up and the disengaging original position.Therefore, the stopper that is used for disposable fuel burner of the present invention has positioner usually, is used for the stopper that is installed in depression or the opening is fixed on original position.Positioner for example can comprise, being used for inserting on the depression of disposable fuel burner or the part in the opening and having one or more grooves of stopper, with the surface of the contacted depression of stopper on or then have the projection of respective numbers in the opening at the top cover of disposable fuel burner.The quantity of projection and groove and size are wanted suitably, so that can stopper be filled in depression or opening by hand, and make it the location, but can pull down stopper by pulling or prizing.

Otherwise, insert on the surface of the depression of disposable fuel burner or the stopper by its opening and can have one or more projections, when stopper was inserted in depression or the opening, these projections can make stopper remain on original position.Usually in this case, projection has an easy fracture part, with box lunch stopper is produced fracture when depression or opening are pulled down, with for convenience detach.Projection generally is projection shape or ligule.Stopper generally has 1 to 8, and common is 2 to 4, and more common is 2 such projections.For example, in the insertion depression of stopper or on the part in the opening, can comprise a circular fin, or two or more projection.

For the ease of from disposable fuel burner, taking off stopper, the top of stopper have usually one can grasping part or device, can apply leverage to stopper by it, so that stopper is taken off from disposable fuel burner.For example, the part at stopper top can cover the upper surface of disposable fuel burner at least, but keeps enough distances with this surface, so that finger, screwdriver or other device can be inserted into the following of top stopper is levered up.For making things convenient for the phase to see, the following of stopper top can have an inside step portion, keeps certain distance so that make between the upper surface of the top of stopper and disposable fuel burner.

Should understand that disposable fuel burner of the present invention can have above-mentioned multiple sealing device simultaneously.

In the another kind of form of the disposable fuel burner of second kind of embodiment of the present invention, the disposable fuel burner that is provided comprises a container that part of fuel is housed at least, also comprises

The bottom surface of a sealing;

The sidewall of sealing;

The first and second wick bearings, determined the space of a sealing therebetween, the first wick bearing is between the fuel and the second wick bearing, at least to there be a wick bearing to be connected across between the sidewall, all have a wick bearing opening on each wick bearing, the first wick bearing has an air inlet at least, and the second wick bearing does not have air inlet;

An elongated loose wick inserts by the wick bearing opening on the wick bearing, and first end of wick is immersed in the fuel, and second exposed end stretches out by the wick bearing opening that is positioned on the second wick bearing;

The size of wick bearing opening wants to guarantee (i) when the disposable fuel burner inversion or when toppling over, and prevents that fuel is by wick and leak out from disposable fuel burner on every side; (ii) when disposable fuel burner is in user mode, allows enough fuel to arrive the exposed end of wick, and can light with sustained combustion at exposed end and exhaust fully until fuel by the capillarity of wick.

Usually, only have an air inlet on the first wick bearing of the disposable fuel burner of second kind of embodiment.

In the disposable fuel burner among first kind and the second kind of embodiment, the size of air inlet openings will guarantee that fuel can not flow out by air inlet openings when container is inverted or is toppled over.Usually, the size of air inlet openings is between 0.1 to 2 millimeter (mm), more commonly between 0.2 to 1mm.Essential understand, if opening size is too little, when disposable fuel burner in use because the consumption of fuel, will produce pressure differential between container inside and outside.This pressure differential can cause the minimizing of flowing of fuel to the exposed end of wick, thereby the size of flame is reduced.Usually, the size of air inlet openings should be greater than guaranteeing that enough air enter in the fuel chambers of disposable fuel burner, to prevent this situation.

Usually, in the disposable fuel burner of the second kind of embodiment that has two wick bearings, it is big that the size of the wick bearing opening of the first wick bearing is wanted, when returning to the use location with convenient stove, allow to enter into the fuel backflow between the first and second wick bearings or be penetrated into fuel chambers, perhaps absorbed by wick.Enter into the fuel between the first and second wick bearings, also can be open closed in fuel chambers by the air inlet on the first wick bearing.

Usually, the space between the first and second wick bearings is big, is enough to prevent to leak into the fuel leak of this enclosure space to the upper surface of the second wick bearing.Usually, this enclosure space is that 4-10mm is wide, and more common width is 5-7mm, although how many this width depends on other size of fuel and disposable fuel burner.In the disposable fuel burner of present embodiment, if have any fuel from fuel chambers, leak out (if for example when disposable fuel burner transports or its when being toppled over), leak out around its wick by wick, air inlet openings or the wick bearing opening by the first wick bearing like this, the fuel of leakage can be retained in the space between the first wick bearing and the fuel retaining device; When disposable fuel burner is ajusted again, or after settling out, fuel will reflux by air inlet openings or by wick and turn back in the fuel chambers, is perhaps absorbed by wick.Like this, this disposable fuel burner according to second kind of embodiment rocks or just can not produce leakage when toppling over running into, unless make this rock or tilt state keeps the sufficiently long time.

In having second kind of embodiment of two wick bearings, any one in the first or second wick bearing, perhaps both can be connected across between the sidewall of disposable fuel burner.For having only a bearing to be connected across situation between the sidewall of disposable fuel burner, another wick bearing is bearing in usually or is fixed on the wick bearing that is connected across on the sidewall.

Can also have a depression on the first wick bearing and/or the second wick bearing, the depression bottom has a wick bearing opening.Usually, have a depression in the second wick bearing.Be preferably with a depression in the wick bearing of disposable fuel burner, this wick bearing can be made by T2, T3 or T4 steel.

In addition, for the wick bearing in the disposable fuel burner of first kind of embodiment, or in the disposable fuel burner of second kind of embodiment when having the second wick bearing (when the second wick bearing has depression), can have one and be looped around depression inside antelabium on every side, the height of wick and adjustable fuel-economizing rope is wanted to hold in the size of antelabium and position, can not be subjected to the obstruction of antelabium with the flame that guarantees exposed end.Generally, antelabium can provide the protection of keeping out wind and rain at the flame of wick exposed end to burning.Antelabium can also make and utilize sealing device sealing disposable fuel burner to become convenient that sealing device has wherein been done detailed description in front.

As mentioned above, in conjunction with first kind of embodiment, the disposable fuel burner of second kind of embodiment can also comprise a top cover that has opening, the wick bearing is between top cover and fuel, and the opening (when having two wick bearings) of the opening of wick bearing (when having only a wick bearing) or the second wick bearing is wanted some opening facing to top cover at least.

In the disposable fuel burner of first kind of embodiment, air inlet openings can be positioned at the edge of contiguous wick bearing expediently.Similarly, in the disposable fuel burner of second kind of embodiment, air openings can suitably be positioned at the vicinity, edge of the first wick bearing.Usually, in this mode of the present invention, disposable fuel burner includes only an air inlet, disposable fuel burner also has a counterweight that is installed on its sidewall, perhaps be installed in the bottom of adjacent perimeter, perhaps be installed on the upper surface or lower surface of sidewall of contiguous disposable fuel burner of a wick bearing, the position of counterweight is in facing to the diameter of air inlet or cornerwise opposite.Counterweight is installed on the inner surface or outer surface of disposable fuel burner.Counterweight generally is installed on the inner surface of fuel chambers of disposable fuel burner.By this structure, when disposable fuel burner being made when roughly cylindrical, in case stove is toppled over, counterweight will cause that disposable fuel burner rolls, and is in the extreme lower position that can reach until counterweight.Under such position, air inlet openings roughly is in the extreme higher position that can reach, and is at this position air inlet more than the normal fuel surface of disposable fuel burner.Like this, just can not leak at this position fuel by air inlet openings.Counterweight can be fixed on the sidewall of disposable fuel burner by any method easily, such as by gluing, welding, soldering, soft soldering, riveted joint or the like.Counterweight generally is bonded on the sidewall.

Similarly, when the disposable fuel burner of first kind of embodiment had a cup-shaped part that is enclosed in around the air inlet, disposable fuel burner also had a counterweight that is positioned at air inlet openings diameter opposite, as mentioned above.

In the disposable fuel burner of first kind and second kind embodiment, it is circular that wick bearing opening is generally.But, also can adopt other shaped aperture, for example, oval, square, rectangle, triangle, hexagon or the like.The edge of wick bearing can also have square profile of tooth or tooth profile.The opening size that should understand the wick bearing of disposable fuel burner of the present invention depends on multiple factor, comprising thickness and the viscosity of fuel and/or the surface tension of wick material type, wick.Here provide some prompting, any people who has a universal experience at the disposable fuel burner technical elements can determine the size of wick bearing opening at an easy rate according to wick material, wick thickness and fuel.

At no matter first kind still in second kind of disposable fuel burner of the present invention, can also have the fray-out of flame device, this fray-out of flame device can be from the use location to extinguishing the position motion, when being in when extinguishing the position, the fray-out of flame device can be so that the fray-out of flame on the wick of disposable fuel burner.Also can make the fray-out of flame device and have an opening and a valve part, when disposable fuel burner was in the use location, the flame that burnt fuel is sent on the wick exposed end was by the opening ejection of fray-out of flame device; And be in when extinguishing the position when disposable fuel burner, valve partly produces action to be stoped and comes in contact between air and the flame, thereby reaches flame-out purpose.

Usually, the use location just is meant, when the sealing bottom surface of disposable fuel burner is in an approximate horizontal surperficial, and the residing position of fray-out of flame device.Extinguish the position and typically refer to, when place the disposable fuel burner side, when for example disposable fuel burner is by accidental knocking over, the residing position of fray-out of flame device.

In first kind of embodiment of the present invention, if having the fray-out of flame device, this device is fit to be placed between the top cover and wick bearing of disposable fuel burner.In second kind of embodiment of the present invention, when having the fray-out of flame device, this device should be installed between the first and second wick bearings, and perhaps between the top cover and the first or second wick bearing, this will be determined on a case-by-case basis.

For example, in the disposable fuel burner of second kind of embodiment, the fray-out of flame device can have a barrel portion simply, has an outside flange near the cylindrical end, then have an inside flange near the other end, thereby form a valve part; Wherein outside flange is sandwiched between two parts in the middle of the first wick bearing, the second wick bearing and the top cover, and when the fray-out of flame device is in when extinguishing the position, this outside flange can be blocked by in above-mentioned two parts.The present invention in this case, when disposable fuel burner was in dump position, the fray-out of flame device moved to and extinguishes the position, and this moment, the valve part covered wick exposed end burned flame at least in part, and prevent that combustible from overflowing from flame region, thereby make fray-out of flame.

In another form, the fray-out of flame device is the disk of a ring-type.In this form, disposable fuel burner can comprise a top cover that has opening, flame can pass through from opening, also comprise two layers of isolating mutually, the fray-out of flame device just is clipped between two layers, when disposable fuel burner is in when extinguishing the position, the annular element of fray-out of flame device is just sealed the opening of top cover, thereby prevents air contact flame and make fray-out of flame.

From this form further, the fray-out of flame device is the rotation valve on a kind of wick bearing that is installed in disposable fuel burner of the present invention, and the valve on the plane that is parallel to the wick bearing can turn to the second place from primary importance; On primary importance, valve can cover burned flame on the wick end that the bearing opening from the wick bearing stretches out, thereby makes fray-out of flame; On the second place, valve does not interdict flame.Usually, valve is roughly plane dish or plate shaped, and it can be circular, square, oval, hexagon, water droplet shape or any shape that other suits.Valve also can be the hemispherical of protuberance or other Any shape that has a rising zone.Usually, valve is installed in rotation on the wick bearing in contiguous its edge, for example be installed in rotation on the pin, and pin is fixed on the wick bearing by neighboring edge place valve.

For simplicity, in this form of the present invention, disposable fuel burner can be made and roughly be cylindric, and has a counterweight that is installed on the sidewall as mentioned above, the fray-out of flame device is installed on the wick bearing, is positioned at the position, opposite along the diametric(al) counterweight.In this case, if disposable fuel burner is knocked over suddenly, it will roll, reach extreme lower position until counterweight, the fray-out of flame device will hang from its rotating shaft, thereby seals the opening of wick bearing, and then extinguishes burned flame on the wick that stretches out from wick bearing opening.

The fray-out of flame device of fray-out of flame device, particularly valve type, the especially rotatable valve type fray-out of flame device of installing can also be as the adjusting device of flame height or size.Like this, when stove in use, the fray-out of flame device moves to one can partly block the position of flame, thereby reduces the height and/or the size of flame.

Usually, in disposable fuel burner of the present invention, the height of wick is adjustable.This can realize until reaching needed wick height by wick is pulled out or pushed from bearing opening or opening usually.And, can regulate the wick height like this for the disposable fuel burner that above the wick bearing, also has a top cover, and promptly earlier wick is pulled out to more than the top cover, according to needed height wick is pushed back space between top cover and the wick bearing then.

Usually, the roughly spherical in shape or taper of the depression in the wick bearing is seen down from the top of wick bearing, is the depression of a circle, and its sidewall is perpendicular to the bottom surface of depression.But, the depression of other shape is also arranged, for example when observing from the top, can be tapered or oval, square, rectangle, triangle, rhombus, hexagon, octagon or the like, or the combination of these shapes.Generally, depression is spherical, perhaps sees rounded from the top and has the approximate vertical sidewall.More common situation is, sees from the top depression is rounded and has the sidewall of approximate vertical, and depression is to form by carry out punching press on the wick bearing.Be in tilt state at stove, under the situation that fuel flows out by air inlet,, exist fuel between top cover and the wick bearing will flow back into the bottom of depression, flow back into fuel chambers by wick then, or absorbed by wick in case stove returns to stand up position.The depression of the disposable fuel burner of first kind of embodiment can extend to sidewall from wick bearing opening always.In this case, depression can make an integral body with sidewall.Alternatively, the diameter of the depression in the wick bearing or full-size can be wick bearing diameter or maximum sized 0.1 to 0.9 times; More common is the diameter of wick bearing or maximum sized 0.2 to 0.8 times, and especially common is wick bearing diameter or maximum sized 0.3 to 0.7 times; The most commonly wick bearing diameter or maximum sized 0.4 to 0.6 times.The degree of depth of the wick bearing depression of the disposable fuel burner among the present invention generally is enough to keep out wind and rain at the flame of wick exposed end for burning.The pocket depth of the wick bearing of disposable fuel burner of the present invention is generally from 4mm to 15mm, and more common is dark from 6mm to 10mm, and the most common is that 8mm is dark.
