Description

413724 V. Description of the invention (π [Background of the invention] ♦ Field of the invention This invention is related to a portable gas burner (gasburner). Specifically, the portable gas burner is: It is mounted on the gas introduction body and can be mounted freely. Burner heads such as gas stoves or gas lamps (1 anter η) used for assembly and disassembly and box-type gas cylinders (bomb). ♦ Description of related technologies. Such portable gas burners have been known in the past, It is disclosed in, for example, Japanese Registered New Type Gazette No. 3027.50. This custom case, as shown in FIG. 7, has the following basic structure. That is, a gas introduction body (101) built into a gas flow regulating valve It is provided with a foldable tripod (102), a gas cylinder matching interface (103), a gas adjustment knob (not shown), and an air-fuel mixing pipe (105), and the gas cylinder is equipped with the interface (103) Attach a freely detachable box-type gas cylinder (106), and connect the above-mentioned air-fuel mixing pipe (105) with a freely detachable gas stove or gas burner head (1 0 7) In this case, 'the gas tank is equipped with an interface ( 1 0 3) It is called micro-inclined fitting. When the gas cylinder is equipped with the interface (1 0 3) and the cassette gas cylinder (1 06) is installed, the bottom edge of the gas cylinder (1 0 6 c) is located at the ground. Height. Moreover, the above-mentioned tripod (102) on the thigh (101a) formed with the body (1 (H) -body) can freely rotate back and forth as shown by arrow A. This structure is: expandable when in use, not used Can be folded inside the above thigh (1 0 1 a). In addition, Figure 7

苐 Page 4 413724 V. The symbol (1 1 8) in the description of the invention (2) is the main air intake with the air-fuel mixing pipe (1 0 5) as the opening -ρ 0 In the above-mentioned conventional example, the gas tank is equipped with an interface (1 0 3) Slightly assembled, so that when this cartridge is fitted with a socket (1 0 6), the bottom edge of the cartridge (1 0 6 c) is at a grounded height And formed. In recent years, due to the diversification of use conditions, gas storage cylinders with different gas storage capacities have begun to be provided, but gas storage cylinders with different capacities have the same diameter and the length of the gas storage cylinder is changed to change its capacity. Therefore, based on the large-capacity gas storage tank, when setting the angle of the gas tank's interface (103), when the small-capacity and short gas storage tank is connected, the bottom edge of the gas storage tank (1 0 6 c ) Is suspended because it cannot be grounded; conversely, if a small-capacity gas tank is used as the reference, the angle of the gas tank's interface (1 0 3) is set. When a large-capacity and long gas tank is connected, the tripod (1 0 2 ) One foot will float because it cannot be grounded. That is to say, when equipped with gas tanks of different capacities, not only will the portable gas burner be set up unstable, but in any case, it will be equipped with a gas tank (106) and an interface (103). ), An improper force is generated and the connection state is unstable. Also, in the above conventional case, since the tripod 002) can be folded under the thigh (1 0 1 a) formed with the body (101), if the tripod (1 0 2) is desired to be tightened, it can be folded. When folded into the outer diameter of the head of a burner such as a gas stove or gas lamp, including the thigh (1 0 1 a), the expansion diameter of the tripod (1 0 2) is limited. At this point, it will also cause carry Type gas burner loses the stability of the placed state. [Summary of Invention]

V. Description of the invention C3) The present invention is designed in consideration of the above situation, and its technical problem is to provide a portable gas burner so that even if it is equipped with gas storage cylinders of different capacities, the placement situation will not become unstable. In addition, the tripod can be tightened when folded, and it can fully ensure the expanded diameter during use, and has excellent placement stability. In order to solve the above problems, the present invention has the following structure: The invention described in item 1 of the scope of patent application is a portable gas burner, which is structured such that a gas is introduced into a body (1) containing a gas flow regulating valve, It is equipped with a foldable multiple tripod (2), a gas cylinder matching interface (.3), a gas adjustment knob (4), and an air-fuel mixing pipe (5), and is individually installed at the above gas cylinder matching interface (3). Freely detachable cassette-type gas storage cylinder (6), and a freely detachable burner head (A) installed on the above-mentioned air-fuel mixing pipe (5); ) When installing the gas cylinder matching interface (3), install the gas cylinder matching interface (3) at a height where the central portion (6 a) of the gas cylinder (6) can be grounded slightly horizontally. This structure allows the gas reservoir (3) to be connected to the middle (6a) of the gas reservoir (6) with a small horizontal ground even when it is connected to a small-capacity, short gas reservoir (6); otherwise, even if it is connected In the case of a large-capacity and long gas cylinder, the middle (6a) of the gas cylinder (6) can also be grounded slightly horizontally. In other words, there is no need to worry about this portable gas even if it is used with gas storage tanks of different capacities. The burner placement becomes unstable. In addition to the structure of item 1 of the scope of patent application, in addition to the structure of item 1 of the scope of patent application, when the above-mentioned gas cylinder (6) is installed slightly horizontally, the direction of the above-mentioned gas cylinder matching interface (3) is arranged so that Can store gas with this gas

413724 V. Description of the invention (4) The tube (6) replaces one of the plural tripods (2). According to this structure, in addition to the advantages described above, because one of the legs (2) corresponding to the gas storage cylinder (6) is omitted, it has the advantage of simplifying its structure. The invention in the third scope of the patent application is a portable gas burner in the first scope of the patent application, which is characterized in that the plurality of tripods (2) can be turned upwards to be mixed with the air-fuel mixture pipe (5 ) Slightly parallel state. With this structure, even when the tripod (2) is long, when it is folded, the tripod (2) does not extend below the gas introduction body (1) and does not exceed the outer diameter of the gas lamp or the like. In addition to the above advantages, it can be tightened when folded, and the expansion diameter of the stand can be fully ensured when in use, so the stability of the portable gas burner in the placed state can be ensured. In addition to the advantages described in the second item, the invention in the fourth item in the patent application scope can also take advantage of the third item. The invention of claim 5 is a portable gas burner according to the scope of patent application 1. The burner head (7 A) for a furnace constitutes the burner head (7), and the burner head (7 A) It is equipped with a grate (1 5). The structural feature of the grate (1 5) is: each base end (1 6 a) of a plurality of grate strips (1 6) is rotated, and can be used during use. It expands slightly horizontally; when not in use, it can be turned down to be slightly horizontal with the air-fuel mixing pipe (5). According to this structure, even if the grate bar (1 6) is long, it can be contracted after folding, and the expanded diameter of the grate bar (1 6) can be fully ensured during use, so it can ensure that the pot or dad is heated by the container ( 3 0) Stability in placement state. In addition to the advantages described in item 2, the invention in item 6 of the scope of patent application has the advantages of item 5.

413724 V. Description of the invention [5]-Please invent the patent for the seventh invention. In addition to the advantages recorded in the third, there are the advantages of the fifth. The invention of item No. 8 in the patent scope is characterized by the portable gas burner of item No. 5, which is characterized in that the above-mentioned hearth bar (1 5) is slightly lower in the use state of the hearth bar (16) due to the low central, The periphery is equipped with a multi-segment container placement section (17) corresponding to the outer diameter of the to-be-added rail σσ (30) 〇 This structure has the advantage of being able to place 17 cr (3 0) of heated outer diameter of different outer diameters. It can be stably placed in the container placement section (1 7). It can be stably placed in use.
