Description

Torch lamp {TORCH LAMP}

The present invention relates to a torch lamp, and more particularly, to a torch lamp having improved preheating structure.

To preheat the gas introduced into the conventional torch lamp is known a torch lamp for butane gas registered utility model (registration number 20-0210400).

7 and 8 are a perspective view and a partial cross-sectional view showing the structure of a conventional torch lamp. As shown in these figures, the conventional torch lamp 1 has a gas amount adjusting member 3 formed on the mounting plate 2 coupled to the butane gas 10, so as to communicate with the gas amount adjusting member 3. The delivery pipe 4 and the flame pipe 6 are provided.

In the flame pipe 6, a partition wall 7 having an injection nozzle 5a is provided so that a space 8 for preheating the inside of the flame pipe 6 is formed. An injection nozzle 5 for injecting gas from the butane gas 10 through the flame pipe 6 is fitted in the connection portion between the delivery pipe 4 and the space 8.

When the conventional torch lamp 1 is mounted on the butane gas 1 and the flame tube 6 is tilted downward, the vaporized gas and the liquefied gas are discharged by the pressure in the butane gas 10. Moving along (4), the primary injection is performed to the space portion 8 by the injection nozzle 5. After the primary injection, it is sent to the flame tube 6 side again through the nozzle 5a installed in the front partition 7 in the state where the vaporization efficiency is increased, and a predetermined flame is obtained by igniting the flame tube 6. Can be.

At this time, the liquefied gas remaining in the liquid state remains in the space 8, but since the heat generated from the flame tube 6 is conducted to the space 8, the liquefied gas is vaporized by the conductive heat so that the nozzle ( Together through 5a).

However, in the conventional torch lamp 1 for butane gas, the cross section of the space 8 is equal to the cross section of the flame tube 6, and the space required for preheating to vaporize the introduced liquid gas is at the same time. While the gas passing through the portion 8 is not sufficiently vaporized, when the flame tube 6 is used at an angle, the liquid gas is ejected and the flame is not generated evenly.

Accordingly, an object of the present invention is to provide a torch lamp that can not only shorten the time required for preheating even when the outside temperature is low, but also prevent the liquid gas from being ejected to form an uneven flame, thereby obtaining a stable flame. will be.

Another object of the present invention is to provide a torch lamp which can form a strong and stable flame by preventing the uneven ejection of gas by changing the flow path of the gas directed to the injection nozzle.

It is yet another object of the present invention to provide a torch lamp that is easily replaceable and repaired locally by allowing some components to be removable.

The object is, in accordance with the present invention, in the torch lamp having a mounting plate coupled to the butane gas, and a gas amount adjusting member coupled to the mounting plate to adjust the amount of gas discharged from the butane gas, the flame is formed A flame tube having an opening; An output pipe having one end coupled to the gas amount control member and the other end disposed in the flame pipe to deliver gas from the butane gas to the flame pipe and having at least one gas outlet formed at the other end thereof; A gas guide member coupled to the other end of the delivery pipe and having a gas ejection flow passage configured to eject the gas in one direction; It is achieved by a torch lamp, characterized in that it comprises a spray nozzle detachably coupled to the gas guide member for injecting the gas ejected through the gas ejection flow path into the opening of the flame pipe.

Here, the gas blowing passage, at least one first passage portion formed in parallel with the longitudinal direction of the flame pipe; And a second flow path portion formed transverse to the first flow path portion and in communication with the first flow path portion at least in some sections. Therefore, not only the efficiency of preheating can be improved, but the time required for preheating can be shortened.

The interior of the flame tube is partitioned into a closed section and an open section by the gas guide member. At this time, a more stable flame can be obtained by forming almost the same ratio of the length of the closed section to the open section.

The gas outlet formed in the outlet pipe communicates with the first passage portion of the gas outlet passage in the closed section.

At least one air hole is formed on a side surface of the flame pipe corresponding to the open section. As the air vent, external air, more specifically oxygen, flows into the flame tube to assist combustion.

Hereinafter, with reference to the accompanying drawings will be described in detail for each embodiment of the present invention and the same reference numerals for the same configuration of each embodiment.

The torch lamp 11 according to the present invention may be used in combination with a portable gas cylinder such as, for example, butane gas 10, as shown in FIGS. 1 to 3.

The torch lamp 11 includes an attachment plate 12 coupled to the butane gas 10 and a gas amount adjusting member 20 coupled to the attachment plate 12 to adjust an amount of gas discharged from the butane gas 10. ), The flame pipe 30, the flame is formed, both ends (40a, 40b) of the discharge pipe 40 and the discharge pipe 40 in communication with the flame pipe 30 and the gas amount control member 20, respectively, The gas guide member 50 provided inside the flame tube 30 while being coupled to the other end 40b and the injection nozzle 60 detachably coupled to the gas guide member 50 are included.

The gas amount adjusting member 20 is connected to the attachment plate 12 and is coupled to the main body portion 22 having a gas discharge passage 22a formed therein, and coupled to the main body portion 22, and the end of which opens and closes the gas discharge passage 22a. It has an opening / closing bar 24 and a knob 26 for operating the opening / closing bar 24.

Accordingly, when the knob 26 is rotated in one direction, the end of the opening / closing bar 24 may open the gas discharge passage 22a (see FIG. 3), and when the knob 26 is rotated in the other direction, the gas discharge passage 22a is closed ( In addition, the opening of the gas discharge passage 22a can be appropriately adjusted by rotating the knob 26 in an appropriate state. The shape of the gas amount adjusting member 20 may employ the method shown in FIG. 1 or may employ the same method as the prior art.

The flame tube 30 has an opening 30a formed at one side thereof so that a flame can be formed by spark ignition at one end thereof. The internal volume of the flame tube 30 may be appropriately designed according to the strength and intensity of the flame to be used.

Flame tube 30 is divided into a closed section (B) and an open section (A) by the gas guide member 50 to be described later, the side of the flame tube 30 corresponding to the open section (A) A plurality of air holes 30b through which outside air, that is, oxygen, flows into the flame tube 30 are formed. In the present embodiment, by forming the length ratio of the closed section B and the open section A in the flame tube 30 to be almost the same (see FIG. 5A), the intensity and intensity of the flame formed in the flame tube 30 are determined. Not only can it be increased, but a more stable flame can be obtained.

The delivery pipe 40 consists of a tubular body having a much smaller cross-sectional area than the flame pipe 30. One end 40a of the delivery pipe 40 communicates with the gas discharge flow path 22a of the gas amount adjusting member 20, and the other end 40b is disposed in the closed section B in the flame pipe 30 so as to provide butane gas ( The gas from 10) is sent out. At this time, it is advantageous that the discharge pipe 40 is welded to the flame pipe 30 so that a gap between the flame pipe 30 and the discharge pipe 40 does not occur. The gas outlet 40c is formed through the side wall adjacent to the other end 40b of the delivery pipe 40. The gas outlet 40c communicates with the first passage portion 52a of the gas ejection passage 52 which will be described later in the closed section B. FIG.

On the other hand, as shown in Figure 4a and 4b, the gas guide member 50 is coupled to the other end (40b) of the delivery pipe (40). To this end, a male thread 40d is formed outside the other end 40b of the delivery pipe 40 and a female thread (not shown) is formed in the gas guide member 50. However, the other end 40b of the delivery pipe 40 may be welded to the gas guide member 50.

The gas guide member 50 has a double cylindrical shape having a predetermined thickness. The gas guide member 50 is fitted in the flame pipe 30 is fit. In the central portion of the gas guide member 50, a groove 50a is formed for the flow of gas in the flame tube 30, but such a groove 50a may not be formed.

In the gas guide member 50, a gas ejection flow path that receives gas delivered from the gas outlet 40c of the delivery pipe 40 and ejects the gas to the opening 30a of the flame pipe 30 through the injection nozzle 60. 52 is formed. The gas ejection passage 52 is formed in parallel with the lengthwise direction of the flame tube 30 and has a plurality of first passage portions 52a formed at one side thereof adjacent to the gas outlet 40c of the discharge tube 40. And a second flow path portion 52b formed transverse to the first flow path portion 52a and in communication with the first flow path portion 52a at least in some sections. 2 and 3, the first flow path part 52a is formed in two parts in the gas guide member 50, and the first flow path part 52a is formed in one part in FIG.

The gas ejection passage 52 not only prevents an uneven ejection state (so-called “byte”) of gas discharged from the butane gas 10 through the discharge pipe 40, but also due to a wide flow passage of gas. The gas guide member 50 can be preheated quickly.

The second channel portion 52b is introduced into the first channel portion 52a of the gas guide member 50 through the gas outlet 40c of the delivery pipe 40 in the substantially central region of the second channel portion 52b. An injection nozzle 60 for precisely injecting the gas flowing through 52b) at high pressure is combined (see FIGS. 4A and 4B).

The injection nozzle 60 has a very narrow injection hole 60a, and the injection hole 60a may be blocked by foreign matter. Thus, in the present invention, when the injection hole 60a is blocked, the injection nozzle 60 is replaced with a new one, or the injection nozzle from the gas guide member 50 to be repaired by drilling the injection hole 60a using a tool such as a needle. 60 is detachably coupled and decoupled. To this end, the injection nozzle 60 and the gas guide member 50 is formed with threaded portions (60b, 50b) that are mutually screwed together.

A method of using the torch lamp 11 having such a configuration will be described below.

First, the attachment plate 12 is coupled to the butane gas 10, and then the knob 26 of the gas amount adjusting member 20 is rotated in one direction in the state as shown in FIG. 22a is opened (see FIG. 3). Then, the gas in the butane gas 10 is sent to the delivery pipe 40 through the gas discharge passage 22a.

The gas sent through the delivery pipe 40 is sent out through the gas delivery port 40c formed at the other end 40b of the delivery pipe 40 to fill the closed section B of the flame pipe 30. The gas filled in the closed section (B) flows into the first flow path portion 52a of the gas guide member 50, and then passes through the second flow path portion 52b to open the injection hole 60a of the injection nozzle 60. Through the opening 30a of the flame tube 30 is injected. At this time, a flame having a desired intensity and intensity may be formed in the opening 30a of the flame tube 30 by igniting a flame in the opening 30a of the flame tube 30.

When a flame is generated in the opening 30a of the flame tube 30, high heat by the flame is generated in the injection nozzle 60 region. The generated high heat is rapid heat transfer to the delivery pipe 40 through the injection nozzle 60 and the gas guide member 50, so that the delivery pipe 40 is quickly heated to pass through the delivery pipe 40. Increase the fraction.

That is, in the conventional torch lamp 11, the time for which the delivery pipe 40 is preheated from the moment of ignition is important, but the gas guide member 50 of the present invention includes first and second flow path portions 52a and 52b. A gas ejection passage 52 is formed, and since gas flows into the first and second passage portions 52a and 52b, the contact area is increased, so that the gas guide member 50 can be preheated quickly.

For this reason, the delivery pipe 40 may also be preheated quickly, so that the mole fraction of the gas gas in the gas passing through the delivery pipe 40 may be higher, so that the ejection state of the gas toward the injection nozzle 60 may be stably made. An air hole formed in the open portion of the flame pipe 30 while the gas discharged from the discharge pipe 40 is injected into the opening 30a of the flame pipe 30 through the injection nozzle 60 while the mole fraction is increased ( By introducing oxygen through 30b), a stable flame having excellent strength and strength may be formed in the opening 30a of the flame tube 30.

Thus, for example, even if the outside temperature is low, such as winter, since the preheating time is much faster than in the prior art, a stable and powerful flame can be obtained.

As such, according to the present invention, even if the outside temperature is low, a short time required for preheating can be obtained to obtain a strong flame. In addition, by changing the flow path of the gas to the injection nozzle 60, it is possible to prevent the non-uniform ejection state of the gas to form a strong and stable flame.

In addition, by allowing some components to be detachable from one another, it is easy to replace and repair a local configuration such as, for example, injection nozzle 60.

In the above-described embodiment, the gas guide member 50 forms the length ratio of the closed section B and the open section A formed in the flame pipe 30 to be almost the same, thereby stably forming the flame.

However, as shown in Fig. 5A, the length ratio of the closed section B and the open section A does not necessarily have to be the same. That is, as shown in FIG. 5B, the opening section C may be formed shorter than the closing section D, and conversely, as shown in FIG. 5C, the opening section E may be the closing section F. It can be formed longer than). In addition, as shown in Figure 5d, by providing the gas guide member 50 directly to the end of the flame pipe 30 may be configured to exist so that only the open section (G).

As described above, according to the present invention, the torch lamp which not only shortens the time required for preheating even when the outside temperature is low, but also prevents the liquid gas from being ejected unevenly, thereby obtaining a stable flame. Is provided.

In addition, by changing the flow path of the gas to the injection nozzle it is possible to prevent the non-uniform ejection state of the gas to form a strong and stable flame.

In addition, by allowing some components to be detachable from one another, local components such as, for example, injection nozzles are easily replaced and repaired.
