Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a burner, and more particularly to a burner suitably used when heating and melting a relatively small amount of wax, wax, etc. into a predetermined shape.

For example, when attempting to treat a patient's teeth using wax or wax in a dental clinic or the like, a portable burner has conventionally been used as a device for heating and melting these materials. When using this burner, in most cases one hand is occupied, so the other hand is used to light the burner, and the wax or wax is placed above the burner and heated and melted.
In other words, it is a one-touch method. Therefore, if the burner nozzle 2 is arranged vertically as shown in FIG. 1, a portion of the melted wax or wax 4 will enter the nozzle 2 and block it. On the other hand, if the crater 2 constituting the burner is arranged so as to face horizontally as shown in Figure 2, part of the melted wax or wax 4 will not enter the crater 2, but the flame will reach the required temperature. There is an inconvenience that you will not be able to get a future. In order to eliminate such drawbacks, a method of tilting the crater 2 at a predetermined angle may be considered (see Figure 3), but even in this case, a part of the wax, etc. that is heated and melted is placed at an angle from the crater 2. There is a difficulty in entering and blocking it.
Especially when wax etc. gets into the small diameter crater 2, it is extremely troublesome to remove it.
Moreover, there is the inconvenience that it takes a long time, and for dentists who are required to provide prompt treatment, encountering such an accident can cause patients complaining of toothache an excessive amount of physical stress.
It also imposes a mental burden.

Therefore, as a result of intensive research and repeated trial production, the inventor of the present invention cut the tip of a vertically extending cylindrical body diagonally at a predetermined angle, and created a block with a larger area at the slanted opening. Attach the board,
If a crater is formed directly below the baffle plate and on the side wall of the cylindrical body, the tip of the flame ejected from the crater will rise vertically, providing the desired temperature to the wax, crater, etc. It was found that some wax, etc. that melts and falls is guided downward along the surface of the baffle plate.In other words, a burner with no risk of clogging the crater was obtained, and the above-mentioned problems were solved at once. .

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a burner that is convenient to carry, easy to handle, and is capable of providing a predetermined temperature and heating effect without clogging the crater with melted wax or the like. It is in.

In order to achieve the above object, the present invention provides a gas storage chamber, a lever member for opening and closing a nozzle for extracting gas from the gas storage chamber, and a lever member for mixing the extracted gas with air and then igniting the mixed fluid. It has an ignition device and a tubular outlet body that guides the flame generated by ignition, the outlet body is vertically arranged and has an upper end inclined, and a side wall portion of the outlet body. In order to form a crater hole in the crater hole and to guide the flame led out from the crater hole obliquely upward, a predetermined portion that closes the inclined upper end of the outlet body and extends sufficiently from the outlet body above the crater hole. It is characterized by providing a baffle plate that is inclined at an angle.

Next, preferred embodiments of the burner according to the present invention will be described in detail with reference to the accompanying drawings.

The locking member 22 having an engraved shape is fixed to the base 10 by screwing the lower screw 20 into a screw hole (not shown) formed in the base 10. A gas introduction pipe 24 extends horizontally from one side of the locking member 22, and a flexible tube 26 is fitted into this. Locking member 2
The second upper thread 18 is screwed into an inner thread 30 formed in the first cylindrical body 28 to define a chamber 32 between the inner thread 30 and the inner thread 30 . Note that this chamber 32 communicates with the tube 26 via a hole 34 formed in the locking member 22 and communicating with the gas introduction pipe 24.

A screw 36 is screwed into the internal thread 30 of the first cylindrical body 28 above the locking member 22, an orifice 38 is formed at the upper end of the screw 36, and a filter 40 is fitted into the lower end opening. do. First cylindrical body 28
In the middle, there is an air inlet 42 extending from the side.
The upper end of the cylindrical body 28 is formed into a nozzle shape and serves as an outlet 44 for upwardly discharging a mixed fluid of gas and air. Next, the second cylindrical body 46 is engaged using the shoulder portion of the first cylindrical body 28. In this case, it is preferable to screw a screw 48 into the first cylinder 28 in order to prevent the second cylinder 46 from rotating. Second
An ignition part 50 that penetrates the side wall of the cylinder 46 and generates a spark is fixed to the cylinder 46. A cylinder 54 is rotatably fitted into the cylindrical protrusion 52 at the top end of the second cylinder 46, and a saucer 56 is rotatably fitted into the lower end of the cylinder 54. Further, in this case, a windshield hood 58 is provided upright on one side of the saucer 56. On the other hand, the upper tip of the cylinder 54 is cut at an angle of about 45 degrees to define a crater hole 60 in its elongated side wall, and a baffle plate 62 is fixed to the opening at the inclined tip. As can be seen from the figure, the baffle plate 62 is fixed so that its upper end protrudes sufficiently forward of the crater hole 60.

Note that the outer circumference of the first cylinder 28 has this cylinder 2.
8 is fitted with an eccentric disk 64 having a relatively inner thickness.
Then, a vertically oriented screw hole 65 is bored in the peripheral edge of the disk 64, and a bolt 66 is inserted through the hole from the bottom surface of the base 10 and screwed into the screw hole 65. In this case, it is preferable to interpose a coil spring 68 between the bottom surface of the disc 64 and the top surface of the base 10.

Therefore, a side plate 70 is constructed by bending a single plate into a U-shape close to the crater portion 14 configured as described above.
A support body 72 having portions a and 70b formed thereon is erected. Next, a pair of holes are drilled in the upper part of the side plates 70a and 70b, and the rod 74 is bridged through these holes, and a pair of small holes are bored in the bottom of these side plates 70a and 70b, and these small holes are similarly filled. and bridge rod 76. The rod 76 has an elastic member 7 approximately in the center thereof, which is made of a single plate and whose upper part is slightly bent.
One end of 8 is wound and fixed, and the other end is made to stand up vertically. Note that in this case, the elastic member 78
A hole 80 is formed in the lower part of the flexible tube 26, and a tube body 84 extending from a locking member 82 secured to one end of the flexible tube 26 is inserted through the hole 80.
The pipe body 84 faces the nozzle portion 86 of the gas cylinder 85 and is used to open and close a nozzle (not shown) of the nozzle portion 86 and to lead out the gas. An opening/closing ring 88 that adjusts the opening area of the nozzle to adjust the amount of gas ejected from the nozzle is fitted into the nozzle part 86. A rod 90 is extended from this opening/closing ring 88 and attached to the bottom surface of the base 10. Make it stand out.

Now, the rod 74 has a first lever member 92.
Also, the second lever member 94 is engaged. 7th
As can be easily understood from FIGS. 8A to 8C, the first lever member 92 is rotatably supported on the rod 74 by side plates 96a and 96b extending downward from the sides thereof. At the same time, one end side of the first lever member 92 is substantially curved so that the elastic member 7
Place it close to 8. The other end of the first lever member 92 extends toward the rear end of the base 10 to form a semicircular tail end, and a hook member 98 is suspended from the center of the tail end. . A claw 100 is formed at the lower end of the hook member 98. Note that the side plates 96a, 96b of this lever member 92
The springs 102a and 102b are wound and fixed around the rod 74 inside the spring 1.
One end of the first lever member 92 is engaged with the lower surface of the first lever member 92, and the other end is connected to the side plate body 70a,
It is attached to 70b.

Next, the second lever member 94 has one end thereof wound around the rod 74, the other end thereof extending toward the tail end of the base 10, and a bent arm 104 extending from the other end. I'll let you. A third lever member 106 is disposed below the tip of the arm 104 on the upper surface of the base 10, and one bent end of the lever member 106 is connected to the arm 104.
A claw 108 is formed at the tip of the lever member 92 and the other end thereof, and is configured to engage with the claw 100 of the first lever member 92. Further, the plate 109 is raised from the upper part of the second lever member 94, and this plate 109 passes through the hole 110 formed in the first lever member 94 and terminates after being bent. A lever 112 is fixed to this bent portion of the plate 108. Further, one end of a spring 114 is engaged with the second lever member 94 via the rod 74, and the other end of the spring 114 is engaged with a curved portion of the first lever member 92.

In addition, in the figure, reference numerals 116 and 118 indicate battery 1.
20, reference numeral 122 indicates a micro switch that is turned on and off by pressing the first lever member 92, and reference numeral 124 indicates a micro switch that is turned on and off by pressing the first lever member 92. Shows the spring for tilting.

The device of the present invention is basically constructed as described above, and its operation and effects will be explained next.

First, if the first lever member 92 is pressed downward as shown in FIG. 8A, the first lever member 92
The second lever member 94, which has a spring 114 attached to its tip end, tilts integrally around the rod 74. When tilted within a predetermined range, the claw 108 of the third lever member 106 engages the claw 1 of the hook member 98.
00 is engaged and the bottom surface of the first lever member 92 is brought into pressure contact with the micro switch 122 to open its normally closed contact (not shown). As a result, the battery 120
The electric circuit including the ignition section 50 is energized, and a spark is emitted from the tip of the ignition section 50.

In addition, during that time, the first lever member 92
When the lever member 92 is tilted, the tip of the lever member 92 comes into contact with the elastic member 78, and the elastic member 78 is slightly inclined as shown in FIG. 8C against the elastic force. Therefore, the locking member 82 and the tube body 84 fixed to the locking member 82 are displaced forward as shown by the arrow, and the nozzle portion 86 is opened. Therefore, gas cylinder 8
The butane gas filled in the chamber 5 flows from the nozzle section 86 through the flexible tube 26 to the hole section 34 and is led out to the chamber 32. The gas that has passed through the filter 40 is vigorously jetted out from the orifice 38.
There, it becomes a mixed fluid with the air introduced through the air introduction port 42, and is ignited by the spark generated by the ignition section 50 as described above. At this time, in the present invention, in particular, the flame outlet is the baffle plate body 6.
2, the flame ejects vigorously from the crater hole 60 not in a straight direction, that is, in a vertical direction, but at an angle of 45 degrees, but the flame tip becomes approximately vertical after leaving the tip of the baffle plate 62.

Therefore, even if wax, wax, etc. is heated at the flame tip in the above state, the partially melted wax, etc. will be blocked by the baffle plate 62 and will not enter the interior through the crater hole 60. Also,
Even if it falls, it will slide down the upper surface of the baffle plate 62 and be received by the saucer 56.

After the work is completed, by pressing only the second lever member 94, the arm 104 tilts the lever member 106, and as a result, the pawl 100 is released from the pawl 108, and the first lever member 92 is released under the action of the spring 102. , to return to its original state. Therefore, the elastic member 78
In order to return to its original state, the nozzle portion 86 is closed and the supply of gas from the cylinder 85 is stopped. Therefore, the flame in the crater hole 60 is also extinguished.

The amount of air supplied can be adjusted by moving the disc 64 vertically by screwing the bolt 66, thereby changing the opening state of the air inlet 42. This helps prevent the flame coming out of the crater hole 60 from being extinguished by the wind.

That is, the device of the present invention ignites by pressing the first lever member using only one hand holding the workpiece, heats the workpiece by holding it in the direction of the flame, and then ignites the workpiece while holding it in that state. The flame can be extinguished by pressing the second lever member.

According to the present invention, as described above, wax, wax, etc. can be heated in the vertical upper part of the flame, and the partially melted wax, etc. is prevented from entering the inside of the flame outlet from the crater. Ru. Therefore,
Since there is no risk of the flame outlet being blocked, there is an effect that heating processing work can be accomplished with peace of mind.

Although the burner of the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and various improvements and design changes can be made without departing from the spirit of the present invention. Of course.
