Description

Disposable oil burner

The present invention relates to disposable oil burners and the fuel and wicks used therein, such oil burners are typically used for heating bain-maries or other situations such as food heating, or to provide low light lighting.

Various types of disposable oil burners have been described above. Typically, existing disposable oil burners include a liquid or gel fuel contained in a container, a wick partially submerged in the fuel, and a wick support through which a portion of the wick passes. The seat sticks out. Some existing oil burners also have a layer of porous flame retardant material in contact with the exposed portion of the wick. In this type of oil burner, the fuel can be ignited as it penetrates through the wick into the porous layer due to capillary action. Typically, the wick support of previous disposable oil burners was a flat metal plate with a hole for the wick to pass through and one or two smaller openings to allow air to enter the oil chamber. In addition, some previous disposable oil burners were in the shape of a thick and low tank with a raised central part on the top to support the oil wick. Out of the oil burner. Such oil burners generally have a multi-part construction.

Existing disposable liquid oil burners suffer from a number of drawbacks. Disadvantages of existing oil burners include:

(a) Some stoves, especially those containing gel fuel, become so hot during combustion and/or after use that they cannot be picked up without proper skin protection;

(b) the outdoor performance of such disposable oil burners is poor because the flame will be unstable in the wind;

(c) oil burners having liquid fuel, or those gel oil burners which become hot in use, are liable to spill fuel from the burner when accidentally knocked over;

(d) in some oil burners, the flame height, i.e. the flame density, is difficult or impossible to adjust;

(e) Some stoves will cause safety accidents if they are hit from the side during use;

(f) for some furnaces, if extinguished for some reason, it is difficult to relight;

(g) Some furnaces are relatively complex and/or expensive to manufacture;

(h) Stoves with gel fuel, when not in use, and sometimes when in use, have an ethanol or methanol odor which is not permitted in a food environment.

Not all prior art disposable oil burners have all of the disadvantages mentioned, but at least one of these disadvantages.

Accordingly, there is a need for improved disposable fuel burners.

It is therefore an object of the present invention to provide an improved disposable fuel burner.

A disposable oil burner proposed according to a first embodiment of the present invention comprises a container at least partially filled with fuel, and also has

a closed bottom;

closed side walls;

A wick support located above the fuel surface and spanning the side walls, at least a portion of the wick support has a recess, the bottom of which has a wick support opening, the wick support also have at least one air intake opening;

A slender, loose wick with one end submerged in fuel and the other end protruding through an opening in the wick support so that the fuel can be burned at the exposed end of the wick.

Typically, the disposable oil burners of the first embodiment have only one air intake opening.

In one form of this embodiment, the air intake opening is located in a pocket of the wick support, such as on a side wall of the pocket, or on the bottom of the pocket. In another form of this embodiment, there is provided a cup-shaped member positioned between the wick support and the fuel, surrounding the air intake opening, and defining between the cup-shaped member and the wick support. A closed space is formed, and there is an air hole in the cup-shaped part. In the disposable oil burner of the first embodiment, the cup-shaped part can contain the fuel flowing out through the air hole, thereby reducing or preventing the leakage of fuel through the air inlet hole on the wick support. Typically, the air holes in the cup are arranged in such a way that fuel entering the cup can flow back through the air holes into the fuel container.

In another form of this embodiment, the disposable fuel burner is provided with valve means actuated in association with the air inlet to prevent fuel from entering through the air when the disposable fuel burner is moved or inverted relative to the position of use. The gas port leaks while allowing air to enter the fuel container when the disposable fuel burner is in the use position.

The valve part may be any convenient device which allows air to enter the fuel container through the air intake opening when the burner is in use, and which allows air to enter the fuel container when the burner is in transport or is tipped or inverted. The flow of fuel through the air intake opening can be prevented (usually substantially prevented). Typically, in this form of the first embodiment, the valve means comprises a flexible plastic or metal membrane which is encapsulated beneath the wick support (that is, on the wick support in the fuel container). side), the membrane or seal has one or more notches through which air can enter the fuel chamber through the air intake opening and notch when the burner is in the use position; and when the burner is in the poured position or inverted , the fuel in the disposable fuel burner presses the membrane and closes the gap tightly, and/or closes the intake opening through the membrane.

For example, the membrane may be encapsulated on the wick support around the edges of the membrane, with the central region of the membrane surrounded by the seal detached from the wick support and overlying the inlet opening. One or more slits are formed in the central area. When the disposable oil burner is in use, air enters the intake opening and passes through the slit in the membrane to the interior of the fuel chamber. However, for example when the disposable fuel burner is turned upside down, the size of the gap ensures that fuel seepage from the fuel chamber is prevented. The number of slits is generally one to two, usually one. The slots are usually straight or V-shaped, but can be of any possible shape.

In another form of the valve arrangement, the peripheral seal used to mount the membrane on the wick support is provided with at least one indentation, the indentation in the seal providing one or more openings for air to enter the fuel chamber . In this form, there is generally no gap in the membrane; that is, the gap in the seal is the passage for air from the intake opening into the interior of the fuel chamber. In this form of valve arrangement, when the disposable fuel burner is in use, air can freely enter the interior of the fuel chamber; but if, for example, the disposable fuel burner is turned upside down, the disposable fuel burner acts on the membrane The pressure compresses the membrane against the wick support, preventing fuel from flowing out through the gap in the seal and the intake opening. Usually, there is only one notch on the seal.

Typically, the membrane is positioned on the wick support such that the inlet opening is away from the gap in the perimeter seal, or the gap in the membrane, as the case may be.

If necessary, the valve assembly may consist of multiple layers of film, with a notch in the seal of each film encapsulated on the wick support and/or on top of each other, or with a seal on each film. A gap, or the combination of the gap and the seal, forms the passage of air from the intake opening into the interior of the fuel chamber. Generally, in the case of a gap in a seal having two adjacent layers of film, or a gap between two adjacent layers of film, the gap or gap should be located as far apart as possible.

The membrane of the valve means may be of any suitable shape, for example, square, rectangular, circular, oval, hexagonal and the like. Usually rectangular, square or round. The film is typically a polymer film such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyvinyl alcohol, the most common of which are polyethylene and polyvinyl chloride. Metallic materials such as tin or aluminum can also be used for the film. The film may be encapsulated on the wick support by any convenient method, including gluing or heat sealing, and/or for metallic material films may be soldered, welded or brazed. It should be understood that the film material and any adhesive used to seal it to the wick support must be inert materials so as not to be affected by the fuel in the disposable fuel burner.

The disposable oil burner may also include a top cover with an opening, the oil wick support is located between the top cover and the fuel, and at least a part of the opening of the oil wick support faces the opening of the top cover. When provided with a top cover, and/or a recess formed in the wick support, it provides weather protection for the flame burning on the exposed portion of the stove wick. Typically, the top cover opening is directly above the wick support opening and is at least as large as, and more commonly larger than, the wick support opening. Common coping openings are circular, oval, square, rectangular, triangular, hexagonal, octagonal, or pentagonal, with circular being the most common. The top cover opening is usually 1 to 5 times the size of the wick support opening, more commonly 1.5 to 4 times the size, and most commonly 2 to 3 times the size. Usually, the size of the opening of the top cover and the distance between the top cover and the oil wick support should be selected to ensure that the oil wick can be pulled out or pressed in through the support opening by hand, and at the same time, it must be ensured that under windy conditions, Provides wind protection against flames.

In this form of the invention, the top cover may act as a retaining means for any fuel that may escape through the intake opening of the wick support, especially when the disposable fuel burner is in its normal upright position, the intake The opening is located in the case of the part covered by the top cover on the wick support.

Therefore, in a second embodiment, the present invention proposes a disposable fuel burner comprising a container containing at least a portion of the fuel, with

a closed bottom;

closed side walls;

a first wick support located above the fuel surface and having a wick support opening and at least one air intake opening;

fuel retaining means at least partially retaining fuel flowing from said inlet opening; an elongated, loose wick having one end submerged in the fuel and the other extending through the wick support opening, the fuel being held in the wick The exposed ends can be ignited.

It should be understood that the wick support of this form in the present invention need not have dimples, but may be completely planar or dome-shaped. However, a flat wick mount or a wick mount with dimples is preferred. When the wick support is completely planar, or has a recess, once the disposable fuel burner returns to its normal upright position, fuel retained between the fuel retaining device and the wick support (e.g. due to a If the permanent oil burner is toppled or inverted to cause fuel to flow out), it can more easily flow back into the fuel chamber through the capillary action of the oil wick.

The fuel retention means is typically a disposable fuel burner top cover having an opening opposite the wick support opening, the top cover bridging the side wall of the fuel burner. For convenience, the inner edge of the top cover opening can be bent downwards, that is to say towards the wick support.

One advantage of such disposable oil burners, particularly those having a generally planar wick support, is that leakage into the fuel retaining device and the oil is eliminated once the burner is returned to an upright position from a dumped or inverted position. The fuel between the wick supports does not pool around the wick and the wick can be easily re-ignited. In addition, the height of the wick can be easily adjusted up and down by pulling it out or pressing it in. When pulled out, the part of the oil wick protruding above the oil wick support can be lengthened; when pressed in, the oil wick can be stored in the space between the fuel retention device and the oil wick support, thereby effectively reducing The height of the small oil wick. In prior art disposable oil burners, once the wick has been pulled through a tight opening, it is often difficult or impossible to reduce the height of the wick.

In another form of this embodiment, the disposable fuel burner has only one air intake opening, which is closed by a cover on or above the upper surface of the wick support, the cover having at least one Open to allow air to enter the space between the cover and the wick mount. Usually, the air inlet of this form is located in the recess of the wick support, and the shape of the cover extends at least partly into the recess. More typically, the inwardly extending perimeter of the pocket in the cover forms a lip that is tangent to the pocket perimeter of the wick support. For example, the cover can be formed with a lip extending inwardly around the seat pocket, the inner edge of the lip is bent towards the surface of the pocket, thereby forming a small gap, usually about 1mm, which provides for the entry of air. opened his mouth. The air intake opening in the pocket on the wick support is located on the surface of the pocket between the pocket circumference of the cover, the wick support pocket surface and the lip.

In addition, or alternatively, a disposable fuel burner in the second embodiment may be provided with a valve arrangement for the inlet opening, which has already been discussed in the first embodiment.

Typically, in such embodiments, the area surrounding the wick support other than the pocket is generally planar, the pocket being a depression formed in the generally planar area of the wick support. Typically, the generally planar region includes the edge from the area surrounding the pocket to the wick standoff, and may contain one or more shallow edges that generally surround the pocket. Having these shallow edges enhances the appearance of the disposable fuel burner.

The wick support may be attached to a portion of the fuel retention device, or extend all the way to the side wall of the disposable fuel burner, or both. Joining may be by any convenient means, for example, gluing, welding, soldering, seaming, crimping, and the like. In a disposable fuel burner according to the invention, the outer edges of the wick support and the fuel retaining means are crimped to the upper edge of the side wall of the disposable fuel burner.

In a disposable oil burner according to the first or second embodiment, the burner is also provided with sealing means to prevent fuel from leaking out of the burner during transportation. In this way, when the sealing device is installed in place, it can effectively prevent fuel from leaking from the disposable fuel burner when the disposable fuel burner is turned upside down or toppled over.

For example, the sealing means may be a removable cover that is sealed mounted on the closed side wall of the oil wick support of the disposable oil burner or on the top cover of the disposable oil burner if the burner has a top cover. In one form, the removable cover can be made repositionable to facilitate extinguishing the flames of fuel burning in the wick if desired. The removable cover can also be made non-resettable. For example, the removable lid may be pressure-fitted into and onto the sidewall of the container or inwardly extending lip, like conventional paint-sealed enclosure lids or other surface finishing methods. A conventional decapper can also be used to remove the lid from the disposable fuel burner container. It is also possible to provide a detachable lid with a helix portion which can be removed from the disposable fuel burner container by unscrewing the lid from the helix corresponding to the side wall of the container. It is also possible to seal the removable cover to the side wall of the disposable fuel burner by means of an annular frangible seal which can be opened under tension. Typically, the removable lid is engageable on a can body. For convenience, the removable cover can have a pull tab for easy removal. Other types of sealable lids will be apparent to those of ordinary skill in the relevant art.

The sealing device can also be a peelable adhesive label, the label is covered on the recess of the oil wick support, and when the disposable fuel burner has a top cover, the label is covered on the top cover of the disposable fuel burner. The material of the label is generally an oil-proof material, and the glue on it should not be affected when it comes into contact with fuel. For convenience, adhesive labels are usually made of a flexible plastic, such as polyethylene, polypropylene, polyvinyl chloride or similar material, and have a peelable adhesive on at least a portion of one side. Usually, the adhesive label is a plasticized polyvinyl chloride (PVC) or metal PVC-based metal, paper, fiber, etc. film. The adhesive is generally acrylic emulsion glue, which can be re-pasted and fixed. Typically, the adhesive label has a grip portion to remove the seal from the disposable fuel burner. It will be appreciated that the seal is most effective when the seal covers both the wick support opening and the wick support inlet.

The sealing device can also be a plug or mandrel that can be opened and tightly inserted into the recess of the oil wick support, or the opening of the top cover of the disposable oil burner. Usually in this case, the seal is a resilient plastic plug sized to seal against the surface or opening of the well, so that if the burner is inverted or tipped over, the plastic stopper prevents fuel from flowing out of the burner. in the leak. When the cavity has an air inlet, it is most effective to adopt such a plug-shaped sealing device that can be installed in the cavity of the wick support.

In certain forms of disposable oil burners of the present invention, the wick protruding from the opening in the wick support may press against the plug inserted into the recess or opening and may lift the plug out of place. Therefore, the plugs used in the disposable oil burners of the present invention are usually provided with retaining means for holding the plugs in place when installed in the recesses or openings. The positioning means may include, for example, one or more grooves on the portion of the plug intended to be inserted into a recess or opening in a disposable fuel burner, and on the surface of the recess that contacts the plug or on the disposable The opening of the top cover of the oil burner has a corresponding number of protrusions. The number and size of protrusions and grooves shall be such that the plug can be inserted and positioned by hand pressure into the recess or opening, but the plug can be removed by hand pulling or prying.

Conversely, the surface of the plug inserted into the recess or through the opening of the disposable fuel burner may have one or more protrusions on its surface which will hold the plug in place when inserted into the recess or opening. Usually in this case, the protrusion is provided with a breakable portion so that when the plug is removed from the recess or opening it breaks to facilitate removal. The protrusions are generally lump-like or tongue-like. Plugs typically have 1 to 8, usually 2 to 4, more often 2 such protrusions. For example, the portion of the plug that is inserted into the recess or into the opening may include an annular rib, or two or more protrusions.

To facilitate removal of the plug from the disposable fuel burner, the top of the plug usually has a grippable part or device by which leverage can be applied to the plug to remove the plug from the disposable fuel burner. For example, at least a portion of the top of the plug may cover the upper surface of the disposable oil burner, but leave a sufficient distance from that surface so that a finger, screwdriver or other device can be inserted under the top to pry the plug off. For convenience, the underside of the top of the plug may have an inwardly stepped portion to allow a certain distance between the top of the plug and the upper surface of the disposable fuel burner.

It should be understood that the disposable fuel burner of the present invention can have the above-mentioned various sealing devices at the same time.

In another form of the second embodiment of the present invention, a disposable fuel burner is provided comprising a container at least partially filled with fuel, further comprising

a closed bottom;

closed side walls;

first and second wick supports defining an enclosed space therebetween, the first wick support being located between the fuel and the second wick support, at least one wick support spanning between the side walls Between, each oil wick support has an oil wick support opening, the first oil wick support has at least one air inlet, and the second oil wick support has no air inlet;

A long, thin, loose wick is inserted through the wick support opening on the wick support, with the first end of the wick submerged in the fuel and the second exposed end passing through the wick support located on the second wick support. the seat opening protrudes;

The size of the opening in the wick support shall be such that (i) when the disposable fuel burner is turned upside down or tipped over, fuel will be prevented from leaking from the disposable fuel burner through the wick and its surroundings; (ii) when the disposable fuel burner is in use In this state, enough fuel is allowed to reach the exposed end of the oil wick through the capillary action of the oil wick, where it can be ignited and continue to burn until the fuel is completely consumed.

Usually, only one air inlet is provided on the first wick support of the disposable oil burner of the second embodiment.

In the disposable fuel burners of the first and second embodiments, the air inlet opening is sized such that fuel does not flow out through the air inlet opening when the container is turned upside down or tipped over. Typically, the size of the inlet opening is between 0.1 and 2 millimeters (mm), more commonly between 0.2 and 1 mm. It must be understood that if the opening size is too small, when the disposable oil burner is in use, a pressure difference will develop between the inside and outside of the container due to fuel consumption. This pressure differential results in a reduction in the flow of fuel to the exposed end of the wick, thereby reducing the size of the flame. In general, the size of the air intake opening should not be larger than to ensure that enough air enters the fuel chamber of a disposable oil burner to prevent this.

Typically, in the second embodiment of a disposable oil burner with two wick supports, the wick support opening of the first wick support is sized larger so that when the stove is returned to the use position , allowing fuel entering between the first and second wick supports to flow back or permeate into the fuel chamber, or be absorbed by the wick. Fuel entering between the first and second wick supports can also flow back into the fuel chamber through the air intake opening on the first wick support.

Typically, the space between the first and second wick supports is large enough to prevent fuel leaking into this enclosed space from seeping onto the upper surface of the second wick support. Typically, this enclosed space is 4-10mm wide, more commonly 5-7mm, although this width will depend somewhat on the fuel and other dimensions of the disposable oil burner. In the disposable oil burner of this embodiment, if any fuel leaks out of the fuel chamber (such as when the disposable oil burner is being transported or if it is dumped) so that it passes through the wick, the air intake opening, or through The oil wick around the opening of the oil wick support of the first oil wick support leaks out, and the leaked fuel will be retained in the space between the first oil wick support and the fuel retention device; when the disposable fuel burner is repositioned Once positive, or stabilized, the fuel is either recirculated back into the fuel chamber through the intake opening or through the wick, or is absorbed by the wick. In this way, the disposable fuel burner according to the second embodiment will not leak when it is shaken or toppled, unless the state of shaking or toppling is kept for a long enough time.

In a second embodiment having two wick supports, either the first or second wick supports, or both, may span between the side walls of the disposable fuel burner. Where only one support spans between the side walls of a disposable oil burner, the other wick support is usually supported or secured to the wick support spanning the side walls.

The first oil wick support and/or the second oil wick support may also have a recess, and the bottom of the recess has an oil wick support opening. Typically, there is a pocket in the second wick support. Disposable oil burners preferably have a recess in the wick support, which can be made of T2, T3 or T4 steel.

In addition, for the oil wick support in the disposable oil burner of the first embodiment, or when there is a second oil wick support in the disposable oil burner of the second embodiment (when the second oil wick support has In the case of a recess), there may be an inwardly facing lip around the recess, the size and position of the lip to accommodate the wick and adjust the height of the wick, so that the flame at the exposed end will not be affected by the lip. hindrance. Typically, the lip provides weather protection from the flames burning on the exposed end of the wick. The lip also facilitates the sealing of the disposable fuel burner with the sealing means described in detail above.

As mentioned above, in combination with the first embodiment, the disposable fuel burner of the second embodiment may also include a top cover with an opening, the oil wick support is located between the top cover and the fuel, and the opening of the oil wick support (When there is only one oil wick support) or the opening of the second oil wick support (when there are two oil wick supports) at least a part must face the opening of the top cover.

In the disposable oil burner of the first embodiment, the air inlet opening may conveniently be located at an edge adjacent to the wick support. Similarly, in the second embodiment of the disposable oil burner, the air opening may be suitably located near the edge of the first wick support. Typically, in this form of the invention, the disposable oil burner comprises only an air inlet and has a counterweight mounted on its side wall, either at the bottom adjacent to the perimeter, or at the On the upper or lower surface of a wick support adjacent to the side wall of the disposable fuel burner, the counterweight is positioned on the diametrically or diagonally opposite side to the air inlet. The counterweight is mounted on the inner or outer surface of the disposable oil burner. The counterweight is generally mounted on the interior surface of the fuel chamber of the disposable oil burner. With this construction, when the disposable fuel burner is made approximately cylindrical, once the burner is tipped over, the counterweight will cause the disposable fuel burner to roll until the counterweight is in the lowest position it can reach. In this position, the air inlet opening is approximately at its highest achievable position in which the air inlet is above the normal fuel surface of the disposable fuel burner. Thus, fuel cannot leak through the intake opening in this position. The counterweight may be secured to the side wall of the disposable oil burner by any convenient method, such as by gluing, welding, brazing, soldering, riveting, or the like. The counterweight is typically glued to the side walls.

Similarly, while the disposable oil burner of the first embodiment has a cup-shaped member surrounding the air inlet, the disposable oil burner also has a counterweight diametrically opposite the air inlet opening, as described above.

In the disposable oil burners of the first and second embodiments, the wick support opening is generally circular. However, openings of other shapes may also be used, such as oval, square, rectangular, triangular, hexagonal, etc. The edge of the wick support can also have a rectangular or toothed profile. It should be understood that the size of the opening in the wick support of the disposable fuel burner of the present invention depends on a number of factors including the type of wick material, the thickness of the wick and the viscosity and/or surface tension of the fuel. As a hint here, anyone with ordinary experience in disposable oil burner technology can easily size the wick support opening based on wick material, wick thickness, and fuel.

No matter in the first or the second disposable oil burner of the present invention, there may also be a flame extinguishing device, which can move from the use position to the extinguishing position. When in the extinguishing position, the flame extinguishing device can make The flame on the wick of the disposable oil burner goes out. It is also possible to make the flame extinguishing device with an opening and a valve part. When the disposable oil burner is in the use position, the flame emitted by the burning fuel on the exposed end of the oil wick is ejected through the opening of the flame extinguishing device; When the permanent oil burner is in the extinguished position, the valve part moves to prevent the contact between the air and the flame, so as to achieve the purpose of extinguishing the flame.

Generally, the use position refers to the position where the flame extinguishing device is located when the closed bottom surface of the disposable oil burner is on a substantially horizontal surface. The extinguishing position generally refers to the position of the flame extinguishing device when the disposable fuel burner is placed on its side, for example if the disposable fuel burner is accidentally knocked over.

In a first embodiment of the invention, if provided with a flame extinguishing device, the device is adapted to be placed between the top cover of the disposable oil burner and the wick support. In the second embodiment of the invention, when a flame extinguishing device is provided, the device should be installed between the first and second wick supports, or between the top cover and the first or second wick supports time, it depends on the specific circumstances.

For example, in the second embodiment of a disposable oil burner, the flame extinguishing means could simply have a cylindrical portion with an outwardly facing flange near one end and an outwardly facing flange near the other end. The inner flange, thereby forming a shutter part; wherein the outward flange is sandwiched between the first oil wick support, the second oil wick support and the two parts of the top cover, when the flame extinguishing device is extinguished position, this outward flange can be blocked by one of the above two parts. In this case of the present invention, when the disposable oil burner is in the dumping position, the flame extinguishing device moves to the extinguishing position, at which time the valve part at least partially covers the flame burning at the exposed end of the oil wick and prevents combustible substances from being released from the flame. Area overflows, extinguishing flames.

In another form, the flame arrester is an annular disc. In this form, the disposable oil burner may comprise a top cover with an opening through which the flame may pass, and two separate layers between which the flame extinguishing device is sandwiched. When the permanent oil burner is in the extinguished position, the annular part of the flame extinguishing device seals the opening of the top cover, thereby preventing the air from contacting the flame and extinguishing the flame.

Further from this form, the flame extinguishing device is a rotary valve installed on the oil wick support of the disposable oil burner of the present invention, and the valve on a plane parallel to the oil wick support can rotate from the first position to the second position; in the first position, the valve can cover the flame burning on the end of the oil wick protruding from the support opening on the oil wick support, so that the flame is extinguished; in the second position, the valve does not Block the flames. Typically, the shutter is generally in the shape of a flat dish or plate, which may be round, square, oval, hexagonal, drop-shaped or any other suitable shape. The shutter could also be raised hemispherical or any other shape with a raised area. Typically, the shutter is rotatably mounted to the wick support adjacent its edge, for example by rotatably mounting the shutter adjacent its edge to a pin secured to the wick support.

For convenience, in this form of the invention, the disposable oil burner can be made generally cylindrical, and with a counterweight mounted on the side wall as mentioned above, the flame extinguishing device is mounted on the wick support on, located diametrically opposite the counterweight. In this case, if the disposable oil burner is suddenly knocked over, it will roll until the counterweight reaches its lowest position, and the flame extinguisher will hang down from its axis of rotation, thereby sealing the opening of the wick support, And then extinguish the flame burning on the oil wick stretched out from the oil wick support opening.

The flame extinguishing device, in particular of the valve type, especially of the rotatably mounted valve type, can also be used as an adjustment device for the height or size of the flame. Thus, when the furnace is in use, the flame arrester moves to a position where it partially blocks the flame, thereby reducing the height and/or size of the flame.

Usually, in the disposable oil burner of the present invention, the height of the oil wick can be adjusted. This is usually accomplished by pulling or pushing the wick out or through the support opening or opening until the desired wick height is achieved. And for the disposable fuel burner with a top cover above the oil wick support, the height of the oil wick can be adjusted in this way, that is, the oil wick is first pulled out above the top cover, and then the oil wick is pressed back according to the required height. to the space between the top cover and the wick support.

Usually, the recess in the oil wick support is roughly spherical or conical, and viewed from the top of the oil wick support, it is a circular depression whose side walls are perpendicular to the bottom surface of the depression. However, there are also other shaped pockets, for example, conical when viewed from above, or oval, square, rectangular, triangular, rhombus, hexagonal, octagonal, etc., or a combination of these shapes. Typically, the depression is spherical, or circular when viewed from above, with generally vertical sidewalls. More commonly, the depression is circular when viewed from above with generally vertical side walls, and the pocket is formed by stamping in the wick support. With the stove in the dumped position and the fuel flowing out through the air inlet, once the stove is returned to the upright position, the fuel that exists between the top cover and the wick support will flow back to the bottom of the well and then flow through the wick Return to the fuel chamber, or be absorbed by the wick. The cavity of the disposable oil burner in the first embodiment can extend from the oil wick support opening to the side wall. In this case, the recess can be formed in one piece with the side wall. Alternatively, the diameter or maximum dimension of the pocket in the wick support may be 0.1 to 0.9 times the diameter or maximum dimension of the wick support; more commonly 0.2 to 0.8 the diameter or maximum dimension of the wick support Times, especially common is 0.3 to 0.7 times the diameter or maximum dimension of the wick support; the most common is 0.4 to 0.6 times the diameter or maximum dimension of the wick support. The depth of the recess of the oil wick support of the disposable oil burner in the present invention is generally sufficient to shelter the flame burning at the exposed end of the oil wick. The depth of the recess of the wick support of the disposable oil burner of the present invention is typically from 4mm to 15mm, more usually from 6mm to 10mm deep, most commonly 8mm deep.

The fuel used in the stove of the present invention may be any known fuel for use in disposable oil fired stoves. The fuel is generally liquid, such as methanol, ethanol, isopropanol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and higher ethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol and higher propylene glycol, the aforementioned Lower alkyl ethers of diols, such as methyl or ethyl ethers. All of the above-mentioned fuels are combustible and easy to catch fire, posing different degrees of combustion hazards. The present inventors have surprisingly discovered that adding a proportion of water to an alcohol or glycol can produce a fuel which can be used in a disposable oil burner, but which lowers the flash point and/or the fire hazard of the fuel.

Thus, a third embodiment of the invention provides a stove, typically a disposable oil burner, wherein the fuel consists of alcohol or glycol and 1% to 30% by volume water. Usually, the amount of water in the fuel is guaranteed. According to the method of Australian Standard 2106, the fuel has no measurable flash point and is therefore not a flammable liquid under the Dangerous Goods Regulations 1978 (New South Wales). Generally, the flash point of a fuel is higher than its boiling point. Common alcohols or glycols are methanol, ethanol, isopropanol, ethylene glycol, propylene glycol, diethylene glycol, or dipropylene glycol. The more commonly used alcohols or diols are ethanol and diethylene glycol. The most commonly used alcohol or diol is diethylene glycol. The volume ratio of fuel to water is 99:1 to 70:30, the more commonly used volume ratio is 99:1 to 80:20, the more commonly used is 97.5:2.5 to 80:20, and the more commonly used one is 90: 10 to 80:20, the most commonly used is 85:15 to 80:20. A very good fuel according to an embodiment of the invention is a mixture of 85% by volume ethylene glycol and 15% by volume water. According to the closed cup method, this fuel has no measurable flash point, its boiling point is about 158°C, and its ignition point is about 162°C.

Disposable oil burners of the present invention are typically made of metal such as aluminium, steel or tin-plated steel. However, other fire-resistant materials such as glass or ceramics can also be used. For convenience, the disposable fuel burner of the present invention may be a refitted tank, or include a refitted tank, such as a tin box used to preserve food, having a wick support opening and an air intake opening on it, It is also possible to make a recess in the lid. In this way, compared with previous disposable fuel burners, for example, compared with the disposable fuel burner that installs a screw cap on the oil wick for convenience of transportation, the disposable fuel burner of the present invention has simple structure and low manufacturing cost. The advantages. In addition, compared with the prior art disposable fuel burner with a screw cap on the oil wick, under the same overall height and width, the fuel storage space of the disposable fuel burner of the present invention is larger.

The disposable fuel burner of the present invention is easy to make, by joining the oil wick support, or when there are many oil wick supports, joining at least one of the oil wick support and the bottom curling on the side wall. This kind of disposable oil burner can be made by first joining the bottom and the side wall together, then filling the fuel chamber so formed, and then joining the oil wick support and the oil wick to the other end of the side wall superior. Before or after the assembly of the wick support and wick is engaged on the side wall, a plug-shaped seal, and/or a peelable label can be attached to the assembly. In a preferred assembly process, the plug and label are made prior to joining the wick support and wick assembly to the sidewall, the joining step being carried out under partial vacuum. In another possible assembly process, the plug and peelable label are installed on the wick support and wick assembly, the fuel in the fuel chamber is preheated, and the wick support, wick The assembly of , plug and tab is bonded to the side wall and finally the fuel is cooled. During these procedures, when the wick support and wick assembly are engaged to the side walls, the pressure developed inside the disposable fuel burner is lower than the pressure outside. In this case, the combination of the stopper and the peel-off label as a sealing means forms a complete airtight seal to the disposable fuel burner, so that the low pressure maintained in the disposable fuel burner eliminates, for example, during storage Problems caused by excessive pressure in disposable oil burners due to temperature rise.

The loose oil wick in the disposable fuel burner of the present invention can be made of any material identical to the oil wick of the disposable fuel burner of the prior art. For example, the oil wick can be made of fiber material, such as cotton, wool, hemp or other natural fiber materials, and can also be made of fiberglass. Fiberglass is a flame retardant material that can be used over and over again. One problem with using fiberglass material is that it can be difficult to relight after the first use. Fiberglass can be replaced by wicks made from natural materials, such as cotton. Typically, such materials tend to cluster into balls once made, and these balls on the exposed end of the wick assist in re-ignition of the wick. However, natural material wicks can cause excessive leakage of fuel through the wick when the burner is placed upside down or toppled over; and when the burner is in use, the wick absorbs too much fuel beyond the Burning needs. Surprisingly, the present inventors have found a composite wick that completely solves the problems posed by these existing wicks.

Therefore, in the fourth embodiment, the present invention also proposes an oil wick for an oil burner, especially a disposable oil burner, the oil wick includes a section of elongated glass fiber, at least one end of the glass fiber is wrapped or Covered with a layer of clustered fuel-absorbent material. Commonly used tufted fuel-absorbent materials are cotton, wool or hemp. A more common tufted absorbable fuel material is terry-terry. Typically, at least the portion of the wick extending through the opening of the wick support of the disposable fuel burner of the first embodiment, or the portion of the wick extending through the opening of the wick support above the disposable fuel burner of the second embodiment The portion of the emerging wick includes tufts of fuel-absorbent material. In another mode, the elongated glass fibers are wrapped with tufted balls of fuel-absorbent material over at least half their length, eg, their entire length.

In another form, the end of the loose fibrous wick extending from the opening of the wick support may be wrapped with a layer of fuel-absorbent material, usually a tufted pellet of fuel-absorbent material. For example, the loose fiber wick may be a fiberglass wick. The wrapping is preferably sewn to one or both, preferably both, of the exposed ends of the fiber wick. Alternatively, the wrapping layer can also be fixed by gluing, or by a stop plate, or by one or more stop blocks made on the wick support.

In another variation, the wrapper of absorbable fuel material may have one or more elongated extensions, each of which may be inserted into an aperture, such as a slot, in the wick support so that the wrapper may be The layers are fixed tightly enough. The elongated portion of the wrapping can be made long enough to reach the fuel of the disposable oil burner through the hole, but it does not have to be. The loose fiber wick can be omitted if the extension of the wrap can reach the fuel, in which case the hole in the wick support through which the extension of the wrap passes can serve as the wick support opening.

Loose fiber wicks can fit loosely in the opening of the wick support, especially when it is sewn onto the layer of fuel-absorbent material of the tufting ball, or it can be fastened tightly to the wick support seat opening. For example, the open edge of the wick support can tightly grip the wick passing through it.

This form of loose fibrous wick and the layer of fuel-absorbent material of the tufted balls generally produces a wider flame than other wick devices that do not include a wrap. In addition, this device makes it easier to relight the flame on the stove when the flame dies out for some reason. The ease of re-ignition of such wick devices is partly due to the greater area of fuel-absorbing material in this wick device than in other wick devices, and partly due to the fact that after the flame is extinguished, A large amount of fuel will accumulate on the wick, and these accumulated fuels can be easily removed by squeezing the coating with your fingers (this, of course, can only be done after a long enough time for the coating to cool down).

In such arrangements, the size of the coating of fuel-absorbent material is usually sufficient to fill the recess in the wick support of the disposable fuel burner.

The present invention also provides a disposable oil burner with the wick device of the fourth embodiment, and a disposable oil burner with a loose fiber wick covered on the exposed end of the loose fiber wick A layer of absorbable fuel material layered with clustered balls.

Usually, the oil wick of the disposable fuel burner of the present invention is about 8-12 mm thick, and the fuel chamber of the disposable fuel burner is roughly cylindrical, with a diameter of about 70-100 mm, usually 85 mm, and a height of about 40-100 mm. The common one is 60mm.

The disposable oil burner of the present invention can conveniently be added with a wind shielding device, which can shield the flame in the stove from wind when used outdoors. Previous disposable oil burners typically lost 30-40% of their heat when exposed to even a small amount of rain, making it impossible to use it as a stove. Prior to the present invention, there was no disposable oil burner combined with a windshield to solve this problem.

Usually, the wind-shielding device of the disposable oil burner of the present invention at least comprises a hole and is used for introducing air on the oil wick of the stove, and the wind-shielding device can generally be placed on the top of the disposable fuel burner or its surroundings, and make the above Air intake openings must not be located on the wind blown side or the rain exposed side of the windshield. The windshield device can be made into any simple shape like this. Usually made the same shape as the cross-section of the disposable fuel burner. That is to say, if the disposable oil burner is cylindrical, the shape of the windshield is also cylindrical, at least at the junction where the windshield is installed with the stove. Typically, the draft shield is sized to allow placement on the upper surface of the disposable fuel burner when in use. The windshield can have many air intake holes. In another simple form, the windshield is generally circular in plan view, but wider at its upper end than at its lower end. Thus, for example, the diameter of the upper end may be 1 to 3 times, more typically 1.5 to 2 times, the diameter of the lower end.

Therefore, the present invention also provides a windshield device for a stove, especially a disposable oil burner. The windshield device is a hollow body with openings at both ends and at least one air inlet hole on the side wall. Typically, at least one of the air intake holes is sized to allow access to the stove wick so that it can be ignited when the draft guard is installed on the stove. Preferably there are two air intake holes sized to reach the wick. It will be appreciated that the distance between the disposable fuel burner and the bottom of the container being heated may vary between different locations or for different uses. Therefore, the ventilation device for the disposable oil burner of the present invention usually also includes a height adjustment device. For example, the windshield may comprise an inner part and an outer part which are slidably mounted inside and outside, means for lifting the inner part relative to the outer part, and means for fixing the inner part to any position on the outer part.

The main body of the windshield also includes a deformable portion, the deformation of which causes one end of the windshield to be raised or lowered relative to the other end. The deformable portion may comprise a, such as a bellows or telescoping portion, by which stretching the ends of the windshield causes the windshield to elongate or heighten, and compressing the ends of the windshield causes it to shorten, lower or Flatten. The deformable portion may form an integral part of the wind deflector or a part of the wind deflector.

In another form, the deformable portion comprises a set of deflectable lugs encircling at least one end of the windshield body by Curving the lugs outboard or inboard of the sides of the windshield body reduces the overall height of the windshield. For convenience, this windshield device according to the present invention can be made of used metal cans for preserving food without lids. This allows the bottom of the can to form a wide circular opening, allowing the draft shield to be fitted over the wick and flame of a disposable oil burner; one or more holes may be cut in the cylindrical part of the can to allow air to flow into the On flame; multiple (usually 15-20) notches may be made in the open end of the circular portion of the can to create a set of bendable lugs parallel to the length of the main length of the can The main axis, usually up to half the length of the body of the can. By bending the lugs so formed inwardly or outwardly (usually outwardly) at different angles relative to the body of the can, the effective height of the windstop can be raised from half the height of the cylindrical portion of the can to the full height .

Using the windshield according to the present invention, when using the disposable oil burner of the present invention on rainy days, the heat loss is usually reduced to 3-5%.

But the fuel 1030 flowing out from the disposable fuel burner 1000 will be reduced to a minimum, and this is because the fuel will flow back into the container 1005 through the air hole 1065, and the fuel 1030 that can flow out through the air inlet 1055 of the disposable fuel burner 1000 will be reduced to a minimum. Greatly reduced, at most only equivalent to the amount of fuel 1030 entering the space 1067.

12A to 12C show an isometric view, a top view and a cross-sectional view, respectively, of a disposable fuel burner of the present invention. Referring to Figures 12A to 12C, the wick support 1140 is a generally planar metal disc with an upwardly raised edge 1145 for engagement on a food can or similar container and a central The recess 1150 has a shallow edge 1146 surrounding the recess 1150 which is perfectly centered with the recess 1150 .

Recess 1150 has a central wick seat opening 1160 and an air inlet 1147 therein. Dimple 1150 forms a spherical indentation in wick mount 1140 as shown. However, the recess 1150 can also be in other shapes, for example, in a top view, it can be square, triangular, rectangular, circular, oval, rhombus, hexagonal, octagonal, in each case, the recess The bottom surface and side walls of 1150 are both substantially vertical.

13A to 13C illustrate a windshield device according to the present invention. An isometric view of the windshield is shown in Figures 13A and 13B. In Figure 13A, the windshield is at full height, while Figure 13B is at a reduced height. FIG. 13C is a top view of the windshield in FIG. 13B in a lowered state.

As shown in FIGS. 13A to 13C , the windshield 1200 is made of a metal can that is cylindrical in shape and has an opening 1220 . As can be seen in Fig. 13C, there is an opening 1240 in the bottom 1230 of the metal can, so that the windshield 1200 can be installed around the wick of a disposable oil burner. A plurality of lugs 1270 are formed on the side wall 1210 of the open top 1220 of the windshield 1200. The lugs 1270 are formed by opening a set of lugs 1270 on the top of a cylinder 1210 (as shown in FIG. 13A ) along a direction parallel to the reference axis of the cylinder. Parallel notches 1280 are made.

Adjacent the bottom surface 1230 of the cylinder 1210 is an opening 1260 to allow air to reach the flame burning in the windshield 1200 . The size of the opening 1260 is such that the stove wick in the windshield 1200 can be ignited by a match, small metal rod, small candle or gas lighter.

The lug 1270 should be bendable. FIG. 13A shows the state of the windshield when the lugs 1270 are not bent, and the windshield 1200 has a maximum height at this time. In Fig. 13B, it can be seen that the lugs 1270 are bent outwards, so that the overall height of the windshield 1200 is reduced.

During use, the windshield device 1200 is installed on the top of the disposable oil burner, such as the disposable oil burner in the present invention, and its bottom surface 1230 is located on the top of the burner. The lugs 1270 can be curved inwardly or outwardly, usually outwardly, in such a way that the combination of the disposable fuel burner and draft shield 1200 obtains the proper distance from the bottom of the vessel being heated. If necessary, the opening 1260 on the windshield 1200 can be turned to the direction of the leeward or the leeward of the rain. This allows the flame on the disposable oil burner to be protected from wind and rain, but allows air to reach the flame through the opening 1260. Like this, compared with the simple device that does not have wind-shielding device, the heat that the flame sends out most can directly heat the container on the stove.

The present invention has a number of advantages over previously known disposable oil burners. Without significantly sacrificing the fuel capacity of the disposable fuel burner of the present invention, the disposable fuel burner of the present invention has many distinct advantages over prior art disposable fuel burners, as follows:

(a) There is a recess on the oil wick support of the disposable oil burner of the first embodiment, or there is a recess on the oil wick support of the second embodiment, and the oil wick is positioned on the support by this device The height above the seat opening can be adjusted arbitrarily, and simultaneously the side wall or the top cover (if there is a top cover) of the container can shield the wind and rain to a certain extent. Thus, the disposable fuel burner of the present invention is more convenient to use in weather conditions than some existing disposable fuel burners.

(b) It has been mentioned above that, in the second embodiment of the present invention, it is difficult for the fuel to splash out of the stove when a sudden side impact is encountered.

(c) When the oil wick is located in the recess of the oil wick support, the flame height produced by the disposable oil burner of the present invention can be adjusted within a wide range, compared with the disposable oil burner of the prior art , can better meet the requirements of the furnace. Thus, for example, the present device allows the use of larger wicks, thereby providing higher flame temperatures for disposable oil burners and extending the usability of disposable oil burners, as compared to at least some prior art stoves.

(d) Since the flame produced by the stove of the present invention is limited to the position of the oil wick, rather than being spread over a wider layer of loose material, it will not contact the material for making the stove, so the fire of the present invention during use The body of the stove simply becomes warm so that it can be picked up and moved to another location while the stove is lit or immediately after the flame steel is extinguished.

(e) With the wick of the present invention, the wick can be re-ignited immediately after the flame has been extinguished without the need to adjust the wick; whereas, at least in some prior art stoves, it is often necessary to turn the wick or Chip off any loose material in contact with the wick (and this is difficult to do when the container is hot). In at least some prior art furnaces with layers of bulk material in contact with the wick, it is easy to dislodge this bulk material when scraping.

(f) Although the stove of the present invention is disposable, it can be recharged relatively easily when the previously charged fuel is exhausted, simply by removing the wick and passing it through the wick support. Simply inject fresh fuel into the opening.

(g) The disposable fuel burners of the present invention, at least in their simplest form, are simpler and less expensive to manufacture than prior art disposable fuel burners. For example, the disposable fuel burner of the present invention can be made of instant food cans, which can be packaged using a food can sealing machine.

(h) Various changes can be easily made to the appearance of the disposable fuel burner (for example, the shape of the recess and the shape and size of the oil wick support) according to the aesthetic needs in specific applications.

(i) During transportation, the disposable fuel burner of the present invention can be sealed with various convenient sealing methods to prevent leakage; while the stove in the prior art can only have one or two sealing methods.

(j) Compared with prior art disposable oil burners with a screw-on lid that sits over the wick, the disposable oil burners of the present invention generally have a larger fuel capacity for the same overall height and width. capacity.
