Technical Field

[0001] The present invention relates to the technical field of gas burners, and particularly to a gas burner with a heat transfer structure for isolating radiant heat. Background Art

[0002] A gas burner is a combustion device that uses different fuels as the main body, such as natural gas, coal gas, etc., mixes them with air for combustion, and then sprays out flames. The burner head is a component in the burner for mixing gas and air.

[0003] In most existing gas burners, the flame is ejected through a nozzle at the burner head. The ejected flame has a high temperature, which will heat the nozzle. After a long combustion time, the heat will radiate to the surrounding of the nozzle. If a person accidentally touches the nozzle, it will cause harm to their body. For this reason, we propose a gas burner with a heat transfer structure for isolating radiant heat to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a gas burner with a heat transfer structure for isolating radiant heat to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A gas burner with a heat transfer structure for isolating radiant heat, including a gas burner body. One side of the gas burner body is fixedly installed with an air inlet box. The outer wall of the air inlet of the air inlet box is fixedly connected with a heat dissipation cold row. One side of the heat dissipation cold row is provided with a pump body fixedly connected to the air inlet box.

[0006] A support cylinder is sleeved outside the nozzle of the gas burner body. The two ends of the support cylinder are respectively fixedly connected with mounting plates. A flexible heat insulation plate is sleeved outside the support cylinder. A high-temperature resistant liquid storage bag is sleeved outside the flexible heat insulation plate. A protective cylinder body is sleeved outside the high-temperature resistant liquid storage bag. The two ends of the protective cylinder body are respectively fixedly connected with mounting plates. A limiting component is arranged on the outer wall of one side of the protective cylinder body, and two connecting pipes are fixedly installed on the outer wall of the other side.

[0007] Preferably, one end of the connecting pipe is fixedly communicated with the high-temperature resistant liquid storage bag through a telescopic pipe. The other end of the connecting pipe is respectively fixedly connected with the pump body through a water pipe.

A circulating water path is formed among the heat dissipation cold row, the pump body, the connecting pipe and the high-temperature resistant liquid storage bag.

[0008] Preferably, the high-temperature resistant liquid storage bag is filled with a coolant. A handle fixedly connected to the protective cylinder body is arranged between the connecting pipes.

[0009] Preferably, tinfoil is fixedly laid on the inner walls of the support cylinder and the flexible heat insulation board. Tinfoil is fixedly laid on the opposite sides of the mounting plate, and a heat insulation layer is provided between the tinfoil and the mounting plate. The thickness of the tinfoil is - centimeters.

[0010] Preferably, after being unfolded, the flexible heat insulation board is in a rectangular body structure and is bonded into a cylindrical structure by magic tape.

Specific implementation mode

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Refer to Figure 1 , 2 , which is the first embodiment of the present invention. This embodiment provides a gas burner with a radiation heat transfer isolation structure, including a gas burner body 1. An air inlet box 2 is fixedly installed on one side of the gas burner body 1. A heat dissipation cold row 3 is fixedly connected to the outer wall of the air inlet of the air inlet box 2. A pump body 4 fixedly connected to the air inlet box 2 is arranged on one side of the heat dissipation cold row 3. When the gas burner body 1 burns and works, the pump body 4 is simultaneously powered on to drive the coolant filled in the high-temperature resistant liquid storage bag 11 to circulate and exchange with the heat dissipation cold row 3. The coolant filled in the high-temperature resistant liquid storage bag 11 absorbs the heat of the radiation heat dissipated by the nozzle of the gas burner body 1. At the same time, the pump body 4 extracts the heat-absorbing coolant into the heat dissipation cold row 3. After the heat dissipation of the heat dissipation cold row 3, the cooled coolant re-enters the high-temperature resistant liquid storage bag 11 to absorb the radiation heat. This cycle continues, and the hot air dissipated by the heat dissipation cold row 3 is discharged towards the air inlet of the air inlet box 2, thereby heating the air at the air inlet position of the air inlet box 2. The fan of the gas burner body 1 extracts external air into it, and the heated air contacts the gas, improving the oxidation reaction speed with the gas and making the gas burn more fully;

[0023] A support cylinder 13 is sleeved outside the nozzle of the gas burner body 1. Both ends of the support cylinder 13 are fixedly connected to mounting plates 6 respectively. A flexible heat insulation plate 12 is sleeved outside the support cylinder 13. A high-temperature resistant liquid storage bag 11 is sleeved outside the flexible heat insulation plate 12. A protective cylinder body 5 is sleeved outside the high-temperature resistant liquid storage bag 11. Both ends of the protective cylinder body 5 are fixedly connected to mounting plates 6 respectively. A limiting component 9 is arranged on one outer wall of the protective cylinder body 5, and two connecting pipes 8 are fixedly installed on the other outer wall. During operation, the protective cylinder body 5 and the support cylinder 13 are sleeved on the nozzle of the gas burner body 1, and then are fixedly connected to the gas burner body 1 through the mounting plate 6 on one side in cooperation with bolts. The mounting plate 6 on the other side cooperates with bolts to fixedly install the gas burner body 1 at the combustion use position. When the gas burner body 1 burns and works, the temperature of the nozzle gradually rises under the heating of the flame of the burner head, and at the same time, heat radiation is generated outward. The tinfoil fixedly covered on the inner wall of the support cylinder 13 reflects the radiant heat, and at the same time, in cooperation with the flexible heat insulation plate 12, the effect of heat transfer is weakened. The radiant heat absorbed by the high-temperature resistant liquid storage bag 11 is extremely small. Finally, under the blocking of the heat insulation plate 10 fixedly connected to the inner wall of the protective cylinder body 5, the radiant heat of the gas burner body 1 is isolated, avoiding the problem that surrounding personnel may be harmed if they accidentally touch the nozzle. By operating the limiting component 9, the protective cylinder body 5 can be opened, which is convenient for replacing the internal flexible heat insulation plate 12 and high-temperature resistant liquid storage bag 11, preventing aging during long-term use and avoiding affecting the isolation effect.

[0024] Embodiment 2

[0025] Referring to Figures 1-5 , this is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, one end of the connecting pipe 8 is fixedly communicated with the high-temperature resistant liquid storage bag 11 through a telescopic pipe. The other end of the connecting pipe 8 is fixedly connected to a pump body 4 through a water pipe respectively. The pump body 4 is fixedly connected to a heat dissipation cold row 3 through a water pipe. A circulating water path is formed among the heat dissipation cold row 3, the pump body 4, the connecting pipe 8 and the high-temperature resistant liquid storage bag 11. The high-temperature resistant liquid storage bag 11 is filled with a coolant. The circulating water path can ensure that the pump body 4 circulates to extract the coolant in the high-temperature resistant liquid storage bag 11, and at the same time, cooperate with the heat dissipation cold row 3 to cool the heat-absorbed coolant. The cooled coolant flows back to the high-temperature resistant liquid storage bag 11 again under the drive of the pump body 4, ensuring the effect of the high-temperature resistant liquid storage bag 11 absorbing radiant heat.

[0026] Specifically, a handle 7 fixedly connecting the protective cylinder body 5 is arranged between the connecting pipes 8. The setting of the handle 7 facilitates the operation of taking the gas burner body 1 and is convenient for moving it to the position where it needs to be fixed.

[0027] Specifically, tinfoil is fixedly laid on the inner walls of the support cylinder 13 and the flexible heat insulation board 12. Tinfoil is fixedly laid on the opposite sides of the mounting plate 6, and a heat insulation layer is provided between the tinfoil and the mounting plate 6. The thickness of the tinfoil is 1-3 cm. The tinfoil reflects radiant heat and, in conjunction with the heat insulation layer, enhances the effect of reducing heat transfer.

[0028] Specifically, after the flexible heat insulation board 12 is unfolded, it is in a rectangular body structure and is bonded into a cylindrical structure by Velcro. The Velcro bonding method facilitates the unfolding and removal of the flexible heat insulation board 12, thereby facilitating the replacement of the flexible heat insulation board 12, avoiding the aging of the flexible heat insulation board 12 during long-term use, and preventing the impact on the effect of isolating radiant heat.

[0029] Specifically, the protective cylinder body 5 is composed of two semi-circular ring plates, and the two semi-circular ring plates are hinged to each other through a hinge 51. The hinged setting facilitates the opening of the protective cylinder body 5, facilitating the operator to replace the internal flexible heat insulation board 12 and the high-temperature liquid storage bladder 11. One end of each of the two ends of the protective cylinder body 5 is fixedly connected to one end of a connecting cylinder 52, and the other end of the connecting cylinder 52 is fixedly connected to the mounting plate 6 respectively. Heat insulation boards 10 are fixedly connected to the inner walls of the protective cylinder body 5 respectively. Tinfoil and a heat insulation layer are fixedly provided on the inner walls of the heat insulation boards 10. At the same time, the mounting plate 6 is also made of heat insulation material. Tinfoil and a heat insulation layer are fixedly provided on the mounting plate 6 located inside the protective cylinder body 5. At the same time, the thickness of the tinfoil and the heat insulation layer is twice the thickness of the heat insulation board 10, enhancing the effect of isolating radiant heat and preventing the temperature of the mounting plate 6 from being too high.

[0030] Specifically, the limiting component 9 includes a support block 91, a limiting frame 92, a groove 93, a threaded rotary rod 94, a rectangular clamping block 95, and an elastic clamping block 96. One end of the support block 91 is fixedly connected to the outer wall of the opposite end of one semi-circular ring plate of the protective cylinder body 5. The limiting frame 92 is fixedly connected to the outer wall of the opposite end of the other semi-circular ring plate of the protective cylinder body 5. A groove 93 is concavely provided on the side of the support block 91 close to the limiting frame 92. The rectangular clamping block 95 is movably arranged in the groove 93. One end of the rectangular clamping block 95 is rotatably connected to the threaded rotary rod 94. Elastic clamping blocks 96 are fixedly connected to both sides of the end of the support block 91 close to the limiting frame 92. When the protective cylinder body 5 is closed into a complete ring, the elastic clamping blocks 96 are respectively clamped on the inner walls of both sides of the "mouth"-shaped limiting frame 92. At the same time, the rectangular clamping block 95 extends into the limiting frame 92 to limit the elastic clamping blocks 96 to prevent the elastic clamping blocks 96 from disengaging. When it is necessary to open the protective cylinder body 5, first rotate the threaded rotary rod 94 to drive the rectangular clamping block 95 to retract into the groove 93. At this time, the elastic clamping blocks 96 can be pushed to disengage from the limiting frame 92, and then the protective cylinder body 5 can be smoothly opened.

[0031] Embodiment 3

[0032] Refer to Figures 1-5, which is the third embodiment of the present invention. Based on the above two embodiments, in use, the protective cylinder 5 and the support cylinder 13 are sleeved on the nozzle of the gas burner body 1, and then fixed to the gas burner body 1 through the mounting plate 6 on one side in cooperation with bolts. The mounting plate 6 on the other side cooperates with bolts to fixedly install the gas burner body 1 at the combustion position. When the gas burner body 1 burns and works, the temperature of the nozzle gradually rises under the heating of the flame of the burner head, and at the same time, heat radiation is generated outward. The tin foil fixedly covered on the inner wall of the support cylinder 13 reflects the radiant heat, and at the same time, cooperates with the flexible heat insulation plate 12, thereby weakening the effect of heat transfer. When the gas burner body 1 burns and works, the pump body 4 is simultaneously powered on to drive the coolant filled in the high-temperature resistant liquid storage bag 11 to circulate and exchange with the heat dissipation radiator 3. The coolant filled in the high-temperature resistant liquid storage bag 11 absorbs the heat of the radiant heat dissipated by the nozzle of the gas burner body 1. At the same time, the pump body 4 extracts the heat-absorbing coolant into the heat dissipation radiator 3. After the heat dissipation of the heat dissipation radiator 3, the cooled coolant re-enters the high-temperature resistant liquid storage bag 11 to absorb the radiant heat. This cycle continues, and the hot air dissipated by the heat dissipation radiator 3 is discharged towards the air inlet of the air inlet box 2, thereby heating the air at the air inlet position of the air inlet box 2. The fan of the gas burner body 1 extracts the outside air into it, and the heated air contacts the gas, increasing the oxidation reaction speed with the gas and making the gas burn more fully. The radiant heat absorbed by the high-temperature resistant liquid storage bag 11 is extremely small. Finally, under the barrier of the heat insulation plate 10 fixedly connected to the inner wall of the protective cylinder 5, the radiant heat of the gas burner body 1 is isolated, avoiding the problem that accidental contact with the nozzle by surrounding personnel may cause harm to their bodies. By operating the limit component 9, the protective cylinder 5 can be opened, thereby facilitating the replacement of the internal flexible heat insulation plate 12 and the high-temperature resistant liquid storage bag 11, preventing aging during long-term use and avoiding affecting the isolation effect.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
