Gas burner

The present invention is a gas burner, especially a gas burner having simultaneous ignition and rapid supply of gas.

According to the fire, it is indispensable for our daily life. With it, we can make cooked food, lighting, and even forging, welding, welding and other metal objects. That is to say, in the case of canned gas, because of the use of liquid gas, it is convenient to either ignite or cook the food whether it is filled with a lighter or combined with a portable gas stove. Therefore, today, canned gas has its irreplaceability.

Based on the convenience of canned gas, the gas burning tools in the workshop exist in two types for users to choose. For example, the U.S. Patent No. 5,466,149 (corresponding to the National Patent Publication No. 271227) and the U.S. Patent No. 5,564,919 (corresponding to the National Patent Publication No. 277674) are exemplified by the creator of the present invention. The mouth of the bottom of the gas burner is connected to the gas outlet valve of the canned gas to inject the liquid gas into the fuel reservoir, thereby providing the gas supply to the gas outlet of the gas burner and the source of the fuel when the combustion device is burned. The other type is the US Patent No. 5,735,353 (corresponding to the Taiwan New Publication No. 329905) and the US Patent No. 5,816,794 (corresponding to the Taiwan New Publication No. 301012). For example, the gas burner is a receiving device below, so as to be connected with the commercially available canned gas, after the gas of the canned gas is vaporized, it is supplied to the whole combustion device for the purpose of melting. Welding, welding or some other burning operation.

The second type of gas burner emits a large amount of gas as a result of the high pressure release of the canned gas, and the solid energy generates a large flame for continuous and large-scale combustion operations.

Referring to FIG. 3 and FIG. 7 , the joint device 2 is attached to the bottom opening 13 of the casing 1 . The joint device 2 has a ring 21 . The joint 21 is provided with a joint portion 211 , which is opened with the top wall. The joint portion 211 is designed according to the joint portion of the top of the canned gas. Therefore, the joint portion 211 is a thread, but not limited thereto. A buffer ring piece 22 is disposed between the inner wall of the ring hole 212 and the joint portion 211, and a connecting portion 231 of the nozzle 23 is passed through the buffer ring piece 22 and coupled to the ring hole 212, and further connected to the fixed end cover 24. In combination, one end of the conveying pipe 25 passes through the fixed end cover 24 and is inserted into the filling nozzle 23 to receive the gas and liquid fuel outputted from the canned gas.

Therefore, when the adapter 21 is connected to the canned gas, the gas and liquid fuel enters through the nozzle 23 and is transported through the delivery pipe 25 to enter the intake control valve 32 in the seat hole 31 of the base 3. The retaining ring 21 is sleeved on the oppositely disposed positioning jaws of the bottom opening 13 by using the positioning groove 213 formed by the top periphery to form a fixing.

As shown in FIG. 3 to FIG. 4 and FIG. 7 to FIG. 10 , the base 3 is an integrally formed seat body, and a bottom-like seat hole 31 is axially opened at the bottom thereof, and the seat hole 31 is provided with an intake control valve 32. Installed to control the disconnection of gas.

The intake control valve 32 is provided with a control rod 321 , a first spring 322 and a second spring 323 from the front end of the seat hole 31 , and is attached to the front end of the seat hole 31 by a front end cover 324 to make the control rod The front end lever 321a of the 321 is extended by the front end cover 324 and is located at the front opening 13. A first ejector valve 325 and a third spring 326 are sleeved into a first valve seat 327, and the first valve seat 327 is inserted into the rear end of the seat hole 31 to make the first and second springs. 322 and 323 are respectively disposed between the control rod 321 and the front ejector valve 325a of the first ejector valve 325 and between the control rod 321 and the first valve seat 327, and the back valve of the first ejector valve 325 The axial displacement of the head 325b is elastically displaced, and the neck valve port 327a of the first valve seat 327 is closed or opened.

The first valve seat 327 has a rear end that is sleeved with a socket 328, and the third spring 326 is disposed between the valve head 325b and the socket 328. The sleeve 328 is sleeved with a filter material 328a, such as a copper sintered body, and finally a rear end cover 329 is attached to the rear end of the seat hole 31, and the intake control valve 32 is mounted on the seat hole 31. Inside. In addition, one end of the conveying pipe 25 passes through the rear end cover 329 and is inserted into the socket 328 so that the conveying pipe 25 is adjacent to the filter material 328a, and the other end of the conveying pipe 25 is coupled to the joint device 2.

An accommodating groove 33 is defined in the other axial direction of the pedestal 3 in the front of the pedestal 3. The accommodating groove 33 is for receiving and positioning a piezoelectric device 34, so that the front button 341 of the piezoelectric device 34 is also located at the front opening. 13 locations. The piezoelectric device 34 is connected to the conductive terminal 343 fixed in the terminal positioning hole 17 by a conductive wire 342. Furthermore, the front opening 13 is sleeved with an axially movable pressing button 14, which is respectively inserted into and adjacent to the button 321a. In addition, the top surface of the pressing button 14 defines a button hole 141 for fastening the rear button 16 .

Therefore, as shown in FIG. 7 and FIG. 8 , when the pressing button 14 is not pressed, the valve head of the first ejector valve 325 is caused by the balance of the elastic extension of the first and third springs 322 and 326. 325b closes the neck valve port 327a of the first valve seat 327, so that gaseous or liquid fuel inside the canned gas combined with the engagement device 2 cannot enter the intake control valve 32 via the delivery pipe 25. Inside.

As shown in FIG. 9 and FIG. 10, when the pressing button 14 is pressed, the pressing button 341 and the lever button 231a are respectively pressed, the lever 321 is axially moved inwardly and the first and second springs 322 are compressed. 323, the first spring 322 is moved against the first ejector valve 325 and abuts the valve port 327a. The valve head 235b of the first ejector valve 325 opens the valve port 327a and compresses the third spring 326. The gas and liquid fuel delivered through the conveying pipe 25 of the joining device 2 quickly pass through the filter material 328a and the valve port 327a in the direction indicated by the arrow, and enter the gas passage 35 communicating with the seat hole 31, the gas passage. The end of 35 is coupled to a first air supply valve 36 for controlling the amount of fuel that is vaporized into the gasification chamber 351 below the stabilizing device 3. The first air supply valve 36 has a second valve seat 361 disposed at the end of the gas passage 35. The second valve seat 361 is fitted with a fourth spring 362 and a second valve seat 361. The second ejector valve 363 of the front end and the rear end of the second ejector valve 363 are attached to the voltage stabilizing device 4.

When the pressing button 14 is continuously pressed, the pressing button 341 triggers the piezoelectric device 34 to generate static electricity, and is transmitted to the position of the air guiding component 54 of the fire-spraying device 5 through a conductive wire 342; since the first spring 322 has abutted The valve port 327a, so the control rod 321 continues to squeeze the first and second springs 322, 323 to absorb the displacement stroke of the control rod 321 without affecting the third spring 326.

As shown in FIG. 3 , FIG. 5 , FIG. 7 , FIG. 8 and FIG. 11 , the voltage regulator 4 is mounted in a stepped coupling hole 352 which is obliquely opened behind the base 3 , and the voltage regulator 4 has a The diaphragm 41, a limiting piece 42, a fifth spring 43, an adjusting seat 44, a fixing base 45, and a knob 46 are formed. The diaphragm piece 41 is an elastic sheet body made of a polymer material, and a peripheral edge thereof is overlapped with the bottom wall of the coupling hole 352, so that a gasification chamber 351 is formed between the diaphragm piece 41 and the first gas supply valve 36, and the gas separation chamber 351 is formed. The vaporization chamber 351 is laterally connected to an air outlet 353 which is opened on the side of the base 1. The diaphragm piece 31 has a pair of followers 411 and a support member 412 connected to the second ejector valve 363 and the fifth spring 43 respectively under the diaphragm 31, and the peripheral edge of the centrally raised limiting piece 42 is overlapped with the diaphragm. Above the 41, the upper half of the support member 412 protrudes from the centrally defined limiting hole 421 of the limiting piece 42 so as to sleeve the end of the fifth spring 43 while the other end of the fifth spring 43 is sleeved. It is disposed on the inner wall of the top of the adjusting seat 44.

The adjusting seat 44 is rotatably screwed into the fixing base 45 and protrudes from the top of the fixing base 45. Then, the fixing base 45 is fixed, for example, riveted to the coupling hole 352. The bottom edge of the fixing seat 45 is pressed against the bottom edge of the limiting piece 42 and the diaphragm piece 41 on the bottom wall of the coupling hole 352, and finally a knob 46 is attached to the shaft 441 of the top of the adjusting seat 44, so that The knob 46 can synchronously rotate the adjusting seat 44 in the fixing base 45, that is, complete the combination of the voltage stabilizing device 3 and the base 1.

Furthermore, the bottom flange 442 of the adjusting seat 44 is axially and radially respectively sleeved with a sealing ring 443 and a friction ring 444. Therefore, when the sealing ring 443 above the flange 442 abuts against the inside of the fixing seat 45 When the wall 451 is blocked, the adjustment seat 44 is moved upward relative to the fixing base 45; and when the adjusting seat 44 is rotated by the fixing base 45, the friction ring 444 is rotated on the inner wall of the fixing seat 45. The frictional interference produces a special feel.

When the voltage stabilizing device 4 is in the closed state, the fifth spring 43 between the adjusting seat 44 and the top surface support member 412 of the diaphragm 41 is in an energy releasing state, so that the diaphragm piece 41 bottom surface follower 411 The second ejector valve 363 is not biased. Therefore, the fourth spring 362 in the first air supply valve 36 is also in the release state, and the second ejector valve 363 is pressed against the second valve seat 361, so that the first The gas supply valve 36 is in a closed state, and it is impossible to inject fuel into the gasification chamber 351 below the regulator unit 4.

As shown in FIG. 11, when the knob 46 is rotated, the adjusting seat 44 is rotated in the fixing base 45, and an axial displacement is generated, so that the adjusting seat 44 forms an energy storage (compression) state for the fifth spring 43. The support member 412, the central portion of the diaphragm 41 and the follower 411 and the second ejector valve 363 are simultaneously moved downward to open the second valve seat 361 of the first air supply valve 36. At this time, the liquid and gaseous fuel delivered by the intake control valve 32 passes through the first air supply valve 36 and enters the gasification chamber 351 to vaporize the liquid fuel that is not completely vaporized, and will be completely The vaporized gas flows to the vent 353.

The end of the air outlet 353 is connected to a plug hole 354, and the air outlet 353 is further connected to a second air supply valve 37. The second air supply valve 37 has a third valve seat mounted at the end of the air outlet 353. 371. The third valve seat 371 is fitted with a sixth spring 372 and a third ejector valve 373 extending through the bottom end of the third valve seat 371. When the third ejector valve 373 is not squeezed, for example, the ferrule 51 of the combustion device 5 is not installed, the third ejector valve 373 closes the third valve seat 371.

Since the second ejector valve 363 has a small aperture, too much gas or liquid fuel that is not completely vaporized will quickly fill and remain in the gasification chamber 351. When the pressure inside the gasification chamber 351 is suddenly increased, the central portion of the diaphragm 41 is elastically displaced upward, and the fifth spring 43 is compressed. At this time, the second ejector valve 363 is moved up and the fourth spring 362 is extended to The second valve seat 361 is closed to stop the supply of gas and liquid fuel.

When the gas inside the gasification chamber 351 is gradually ejected through the second air supply valve 37, the internal pressure of the vaporization chamber 351 is gradually decreased, and at this time, the fifth spring 43 is extended, and the support member 411, the central portion of the diaphragm 41, and the slave are pushed. The movable member 412 is displaced downward, thereby causing the second ejector valve 363 to move downward, and compressing the fourth spring 362 to re-form the supply state of the gas and liquid fuel as shown in FIG. In fact, since the fuel flows rapidly between the intake control valve 32, the first air supply valve 36, the voltage regulator 4, and the second air supply valve 37 in the susceptor 1, the diaphragm 41 and the second are made. The ejector valve 363 also moves rapidly and repeatedly, so that the liquid fuel can be completely vaporized into a gas, and a constant pressure effect is obtained.

Therefore, by rotating the adjusting seat 44, it is axially raised and lowered in the fixing base 45, and the pressure adjustment of compressing or stretching the fifth spring 43 between the adjusting seat 44 and the support member 412 above the diaphragm piece 41 is performed. The pressure applied to the diaphragm 41 by the fifth spring 43 is greater than the fourth spring 362 and the fuel pressure in the first air supply valve 36, and the pressure applied by the fifth spring 43 to the diaphragm 41 is less than the gas. When the pressure of the fuel in the chamber 351 is vaporized, the diaphragm 41, the support member 412 and the follower 411 reciprocally synchronously drive the second ejector valve 363 to move, thereby opening or closing the second of the first air supply valve 36. The valve seat 361 further adjusts the fuel pressure entering the inside of the gasification chamber 351 and the gas output from the vaporized gas to the outlet hole 353.

As shown in FIG. 6, FIG. 7, and FIG. 9, the fire-spraying device 5 is inserted into the insertion hole 354. The bottom of the sleeve 51 is coupled with a nozzle holder 511. The third ejector valve 373 is joined and squeezed to cause the completely vaporized gaseous fuel to be ejected by the air nozzle 512 attached to the top end of the jet seat 511. The air nozzle 512 is provided with a filter material 514, such as a copper sintered body, to filter the gas passing through the nozzle block 511. Further, a plurality of vent holes 513 are defined in the middle of the sleeve 51 so that air passes through the top of the casing 1. The air guiding groove 18, which is preset on both sides of the opening 13, is introduced and enters the socket 51 through the vent hole 513 to be mixed with the gas discharged from the air nozzle 512 to form a mixed gas.

In addition, the socket 51 is sleeved in a loading and unloading base 52 and combined with an outer tube 53. The loading and unloading base 52 radially protrudes from an electric chamber 521, and a contact terminal 522 is fixed in the electric chamber 521. A cover 523 is closed to the electrical chamber 521. The contact terminal 522 is connected to a wire 524 into the outer tube 53, and the end of the wire 524 is fixed to the wire positioning ring 531 in the front end of the outer tube 53.

In order to generate a special flame effect, a gas guiding component 54 that can guide the flow direction of the mixed gas is installed in a fire-breathing tube 55, and is fastened to the gas guiding component 54 by a pressing ring 541. Inside the squib 55. Finally, an extension tube 56 is sleeved to the front end of the squib 55, that is, the assembly of the squirting device 5 is completed. Wherein, the air guiding component 54 is, for example but not limited to, a cross-shaped rotating member, so that when the mixed gas passes through the cross-shaped rotating member, a swirling flame can be generated to enhance the combustion effect.

The step of attaching the fire-spraying device 5 to the housing 1 and the base 3 is to first insert the loading and unloading base 52 into the top opening 13 of the housing 1 and rotate it by a predetermined angle, for example, 90 degrees, so that the loading and unloading seat The second air supply valve 37 is fixed to the top of the casing 1 and the nozzle seat 511 at the bottom of the sleeve 51 is inserted into the insertion hole 354 formed at the top of the base 3 to form a gas-tight connection between the second air supply valve 37 and the nozzle holder 511; When the loading and unloading base 52 is rotated to the positioning, the contact terminal 522 of the electric chamber 521 is in contact with the predetermined conductive terminal 343 of the top surface of the casing 1, that is, the electrical connection of the piezoelectric device 34 to the outer tube 53 is formed. On the other hand, if the fire-spraying device 5 is to be disassembled, only the reverse rotation is required to make the fire-breathing device 5 and the top opening of the casing 1 unlock and pull away, so that the conductive terminal 343 and the contact terminal 522 and the second can be made. The air supply valve 37 is separated from the nozzle holder 511, and the second air supply valve 37 is closed to prevent leakage of gas.

Therefore, when the push button 341 of the piezoelectric device 34 is compressed by the push button 14, the generated static electricity is transmitted through the wire 342, the conductive terminal 343, the contact terminal 522 and the wire 524, so that the wire 524 and the guide in the squib 55 are guided. The gas assembly 54 generates a static spark to ignite the mixed gas passing through the gas guide assembly 54.

When the bottom jet seat 512 of the squib 51 of the fire-breathing device 5 is not inserted into the insertion hole 354, the third ejector valve 373 closes the third valve seat 371 due to the extension of the sixth spring 372 to form a gas shut-off. When the bottom jet seat 512 is inserted into the insertion hole 354, the bottom nozzle holder 511 of the socket 51 pushes the third ejector valve 373 to compress the sixth spring 372 to pass the gaseous fuel through the third valve seat. 371, after entering the nozzle holder 511, filtering through the filter medium 514, and ejecting from the tip end nozzle 512.

As shown in FIG. 3 and FIG. 12 , the housing 1 further includes a continuous button 16 , and the continuous button 16 is sleeved on the front upper opening 13 of the housing 1 , and the continuous button 16 is longitudinally sleeved with a seventh spring 161 . The bottom of the seventh spring 161 abuts against a flap 19 inside the casing 1, so that the continuous key 16 has an automatic return function. Wherein, the continuous button 16 is provided with a hook 162 at the longitudinal bottom. When the pressing button 14 is in the retracted state of the pressing, the pressing button 16 can be directly pressed, so that the buckle 162 and the buttonhole 141 of the pressing button 14 form a fastening state as shown in FIG. 12, so that the pressing button is pressed. After the external force is pressed, the air intake control valve 32 in the base 3 can continue to supply the gas to the voltage stabilizing device 4 unless it is automatically returned.

As shown in FIG. 3 and FIG. 13 , the housing 1 of the present invention further includes a safety key 15 which is sleeved on the front lower opening 13 of the housing 1 and at least one stop 151 is protruded from the top surface. The bottom surface of the pressing button 14 corresponds to the position of the stop 151, and the stopper 142 abuts against the stop 151, so that the pressing button 14 forms a locked state that cannot be pressed. To press the push button 14, the safety button 15 only needs to be pushed laterally so that the stop 151 is disengaged from the stop 142, and the push button 14 is formed into a depressible unlocked state.

In the actual operation of the case, please refer to FIG. 1, FIG. 2, FIG. 7 and FIG. 8.
