Description

Technical Field

[0001] The present invention relates to the technical field of gas combustion, and in particular to a direct-injection high-heat-intensity blue-light infrared gas appliance. Background Art

[0002] Gas burners generally include atmospheric burners and infrared burners. Atmospheric burners are widely known for their high popularity, while infrared burners have received increasing attention in recent years for their high efficiency, energy saving, environmental protection, and low carbon characteristics. However, infrared burners are currently too large, relatively complex in structure, and their manufacturing costs are much higher than atmospheric burners, which greatly limits their popularization and application. According to reports, the current penetration rate of infrared civilian stoves is only 3%, which has great market prospects. Therefore, it is extremely necessary to develop infrared burners with small size, simple structure, and high heat intensity. Secondly, the frequency of outdoor camping activities has shown a significant increase, and the demand for outdoor burners has surged. However, the current outdoor infrared burners still fail to meet the user experience well, mainly manifested in the following points:

[0003] 1. The heat intensity is low, and it is necessary to increase the heat load by increasing the fire hole area of ​​the burner to meet the fast heat dissipation environment of outdoor cooking. Therefore, outdoor stoves need to be larger in size, but the large size poses great challenges to cost control and portability.

[0004] 2. At present, the area heat intensity of household gas infrared burners is about 140-200kW / ㎡, and the maximum heat intensity of infrared outdoor cassette stoves is about 300kW / ㎡. This means that according to the above heat intensity, in order to achieve a moderate heat load of 3kW for outdoor applications, the effective combustion surface of the burner is about Φ113-Φ165, and the burner size is about Φ123-Φ175. This area also needs to take into account the setting of the stove size, which is not easy to accept for outdoor burning appliances.

[0005] 3. Infrared burners with high thermal intensity are prone to backfire, especially in the field of high-pressure outdoor camping stoves. The gas pressure is often as high as 100,000 or even millions of Pa. In addition, the pressure of disposable gas cylinders fluctuates greatly with the consumption of gas and the influence of gasification and cooling. In order to adapt to the premise of large fluctuations in gas pressure, high-thermal-intensity infrared burners are produced. In order to prevent backfire, the conventional structure is relatively complex, and the height of the burner cavity must also be increased, so the volume is also large.

[0006] 4. High thermal intensity means that more gas combustion reactions are completed per unit fire hole area, which means that the probability of incomplete combustion of gas increases, resulting in a sharp increase in the CO concentration in the flue gas. Large changes in gas pressure will also cause the operating conditions to deteriorate under certain pressures, leading to an increase in CO.

[0007] 5. High thermal intensity and small head area will cause the gas flow rate to increase sharply. During cold ignition, the high-speed airflow will carry away the heat and it will be difficult to reach the ignition point of the gas, resulting in ignition failure. Current technology usually adopts the method of constantly open flame and adding atmospheric ignition burner to achieve this, but it is not friendly to the size and cost of the stove.

[0008] 6. Although the wind resistance of the current product meets the technical standards and has good effects, it cannot make up for the impact of strong outdoor winds on the deterioration of heating and ignition performance. In addition, it may even be necessary to add windproof components, which will increase costs and reduce portability.

[0009] In view of this, it is necessary to propose further improvements to the current structure. Summary of the Invention

[0041] Please refer to Figures 1 to 10 The present invention provides a direct-injection high-heat-intensity blue-light infrared gas appliance, comprising:

[0042] The combustion element 1 includes a furnace body 11 and an ejector pipe 12 which are interconnected. A premixing adjustment plate 6 adapted thereto is fixedly connected to the furnace body 11. The ejector pipe 12 is provided with a plurality of air inlets 1211.

[0043] The flame stabilizing member 2 is arranged at one end of the furnace body 11 away from the ejector tube 12, and the flame stabilizing member 2 is arranged opposite to the premixing adjustment plate 6. The flame stabilizing member 2 is also provided with an ignition ground electrode 711;

[0044] The ignition element 3 is disposed in the furnace body 11 and further includes an ignition positive electrode 31. The ignition positive electrode 31 is disposed through and exposed to the flame stabilizing element 2. The ignition positive electrode 31 is disposed adjacent to the ignition ground electrode 711.

[0045] The nozzle member 4 is connected to one end of the ejector tube 12 away from the furnace body 11 .

[0046] In this embodiment, the combustion element 1 includes a furnace body 11 and an ejector tube 12 that are interconnected. The furnace body 11 and the ejector tube 12 are connected in an integrally formed manner. The connection manner between the furnace body 11 and the ejector tube 12 is not limited and is set according to the actual production method.

[0047] In this embodiment, a flame stabilizer 2 is provided at the end of the furnace body 11 away from the ejector tube 12. The dimensions of the flame stabilizer 2 are compatible with those of the furnace body 11, allowing it to be securely attached to the furnace body 11. An ignition element 3 is also provided within the furnace body 11. The ignition element 3 is equipped with an ignition positive electrode 31, which extends through the flame stabilizer 2 and is exposed therefrom. Furthermore, an ignition ground electrode 711 is provided on the flame stabilizer 2. The ignition ground electrode 711 is positioned adjacent to the ignition positive electrode 31, allowing a discharge to occur between the ignition ground electrode 711 and the ignition positive electrode 31, igniting the combustible gas mixture that flows from the ejector tube 12 to the furnace body 11 and then to the surface of the flame stabilizer 2. A nozzle 4 is also connected to the end of the ejector tube 12 away from the furnace body 11, allowing high-pressure gas to be ejected vertically upward from the nozzle 4 into the ejector tube 12. The ignition ground electrode 711 is an electrically connected ground electrode.

[0048] Specifically, a premixing regulating plate 6 is fixedly connected to the furnace body 1, and the premixing regulating plate 6 is arranged above the ejector pipe 12. The ejector pipe 12 is provided with a plurality of air inlets 1211. When the high-pressure gas is sprayed into the ejector pipe 12, the pressure difference is used to suck air from the air inlets 1211 perpendicular to the gas flow direction. The high-pressure gas and air are mixed in the ejector pipe 12 and the furnace body 11. When they pass through the ejector pipe 12 and enter the furnace body 11, the front of the premixing regulating plate 6 arranged above the ejector pipe 12 will block most of the mixed gas, so that it cannot enter the furnace body 11 and can only be reflected into the ejector pipe 12. The airflow produces vertical collision, and the uniformity of the mixed gas in the ejector pipe 12 is further improved. At the same time, the airflow vertically upward from the ejector pipe 12, that is, along the axial direction of the furnace body 11, is affected by the premixing regulating plate 6 is blocked on the front side and changes its path to flow and diffuse in the radial direction of the furnace body 11. The radial airflow is partially reflected after hitting the inner wall of the furnace body 11, and the reflected and rebounded gas continues to collide and mix with the forward gas. The mixed gas finally enters the space between the flame stabilizing part 2 and the premixing adjustment plate 6 through the gap between the premixing adjustment plate 6 and the inner wall of the furnace body 11, and finally forms a uniform combustible gas through the homogenization effect of the mutual interpenetration of the flame stabilizing part 2 and each mixed airflow to reach the surface of the flame stabilizing part 2. That is, the premixing adjustment effect of the premixing adjustment plate 6 is equivalent to extending the path of diffusion mixing, so that the gas and air are more fully mixed, which can greatly shorten the length of the ejector tube 12 and also reduce the size of the end of the furnace body 11 where the flame stabilizing part 2 is provided, and the total volume is also greatly reduced, thereby greatly improving the thermal intensity.

[0049] Specifically, high-pressure gas is sprayed vertically upward from the nozzle member 4 into the ejector tube 12, and the pressure difference is used to draw air from the air inlet 1211 perpendicular to the gas flow direction of the ejector tube 12. The high-pressure gas and air are mixed in the ejector tube 12 and vertically enter the furnace cavity 11. The premixing adjustment plate 6 fixed inside the furnace cavity 11 extends the premixing path and adjusts the distribution of the mixed gas, effectively shortening the axial length of the ejector tube 12 and the radial size of the furnace cavity 11, efficiently forming a uniform combustible mixed gas, and reaching the surface of the flame stabilizing member 2 at the head of the furnace body 11, while making the air flow at the edge slightly larger than that in the middle. The gas is ignited by the ignition positive electrode 31 of the ignition member 3 built into the furnace body 11 and the ignition ground electrode 711 on the surface of the flame stabilizing member 2 through an electric arc, and most of the gas is distributed in most of the area in the middle area of ​​the flame stabilizing member 2 to form infrared combustion, while atmospheric combustion with a blue flame and micro-flame is formed at the outer edge, thereby achieving efficient combustion and high thermal intensity of the burner, effectively reducing the volume of the burner and making it more portable.

[0050] Among them, the nozzle part 4 is vertically arranged below the ejector tube 12, so that the high-pressure gas can be vertically sprayed into the ejector tube 12 through the nozzle part 4. The nozzle part 4 and the high-temperature plane of the flame stabilizing part 2 are vertical and far away, and an air inlet 1211 is also provided at the ejector tube 12, so that the nozzle part 4 is continuously cooled, so the temperature rise is low, and the risk of backfire is minimized.

[0051] Furthermore, the furnace body 11 includes a first cavity 111 and a second cavity 112 that are connected to each other. A through hole 1121 is provided at the center position of the second cavity 112 near the ejector tube 12. The second cavity 112 is connected to the ejector tube 12 through the through hole 1121. The position of the through hole 1121 corresponds to the center of the premixing adjustment plate 6. A plurality of first connecting members 1122 are evenly distributed around the through hole 1121, and are connected to a plurality of support members 61 on the premixing adjustment plate 6 through the plurality of first connecting members 1122. A plurality of guide holes 62 are also evenly distributed on the edge of the premixing adjustment plate 6.

[0052] In this embodiment, the interior of the furnace body 11 includes a first cavity 111 and a second cavity 112 that are interconnected. The cross-sectional size of the first cavity 111 is larger than the cross-sectional size of the second cavity 112. A through hole 1121 is provided on the side of the second cavity 112 close to the ejector tube 12, and the second cavity is connected to the ejector tube 12 through the through hole 1121, so that the first cavity 111, the second cavity 112 and the ejector tube 12 of the furnace body 11 are interconnected. The through hole 1121 is arranged at the central axis position of the second cavity 112, and a plurality of first connecting members 1122 are evenly distributed around the through hole 1121. A premixing adjustment plate 6 adapted to the shape of the furnace cavity 11 is arranged above the first connecting member 1122. A plurality of supporting members 61 are evenly arranged on the bottom of the premixing adjustment plate 6, and are connected to the first connecting member 1122 through the plurality of supporting members 61, so that the premixing adjustment plate 6 is fixedly connected to the furnace body 11, that is, the center position of the premixing adjustment plate 6 is also the position of the through hole 1121.

[0053] Specifically, a plurality of evenly distributed guide holes 62 are provided at the edge of the premixing adjustment plate 6, while no guide holes are provided in the middle portion above the through hole 1121. This allows the mixed gas in the ejector tube 12 to be blocked by the premixing adjustment plate 6. The mixed gas can not only enter the space between the flame stabilizing member 2 and the premixing adjustment plate 6 through the gap between the premixing adjustment plate 6 and the inner wall of the furnace body 11, but also enter the space between the flame stabilizing member 2 and the premixing adjustment plate 6 through the guide holes 62 provided on the premixing adjustment plate 6. Finally, a uniform combustible gas is formed through the homogenization effect of the mutual interpenetration of the flame stabilizing member 2 and each mixed airflow to reach the surface of the flame stabilizing member 2, and the combustible gas is ignited by the arc generated between the ignition positive electrode 31 and the ignition ground electrode 711.

[0054] The number of the first connecting members 1122 and the number of the supporting members 61 are the same, 4 in this embodiment, and the first connecting members 1122 are specifically rivets.

[0055] Furthermore, a supporting step 1111 is provided on the inner wall of the first cavity 111, and a flame stabilizing member 2 is tightly provided on the supporting step 1111, and the flame stabilizing member 2 is arranged in contact with the inner wall of the first cavity 111, and the flame stabilizing member 2 is provided with a plurality of fire holes, the size of the fire holes is larger than the size of the ignition positive electrode 31, the ignition positive electrode 31 passes through the fire holes and is exposed on the flame stabilizing member 2, and the material of the flame stabilizing member 2 is a porous insulating refractory material.

[0056] In this embodiment, a plurality of fire holes are provided on the flame stabilizing member 2, and a supporting step 1111 is provided on the inner wall of the first cavity 111. The flame stabilizing member 2 is tightly installed on the supporting step 1111. The supporting step 1111 is a flat horizontal surface, and the size of the flame stabilizing member 2 is adapted to the cross-sectional size of the first cavity 111, so that the flame stabilizing member 2 can be tightly abutted against the inner wall of the first cavity 111, thereby ensuring the sealing of the flame stabilizing member 2 and ensuring that the mixed combustible gas will not leak out from the side of the flame stabilizing member 2, but will only reach the head surface of the combustion member 1 through the fire holes of the flame stabilizing member 2.

[0057] Among them, the size of the fire hole of the flame stabilizing member 2 is slightly larger than the size of the ignition positive electrode 31, so that the ignition positive electrode 31 can pass through the fire hole and be exposed at the fire hole. Since an ignition ground electrode 711 is provided on the flame stabilizing member 2, the ignition positive electrode 31 needs to be exposed outside the fire hole, so that an arc can be generated between the ignition positive electrode 31 and the ignition ground electrode 711 to ignite the combustible gas on the surface of the flame stabilizing member 2. The material used for the flame stabilizing member 2 in this embodiment is a porous insulating refractory material, which is a non-conductive insulating material and also a refractory material, which can prevent the ignition positive electrode 31 and the ignition ground electrode 711 from short-circuiting.

[0058] Furthermore, the ejector tube 12 includes a third cavity 121 and a fourth cavity 122 that are connected to each other. The inner side wall of the fourth cavity 122 is provided with a connecting thread 1221 for connecting the nozzle member 4. The third cavity 121 is connected to the second cavity 112 through a through hole 1121, and a plurality of air inlets 1211 are opened through the outer wall of the third cavity 121 near the fourth cavity 122. The first cavity 111, the second cavity 112, the third cavity 121 and the fourth cavity 122 are connected to each other, and the cross-sectional dimensions of the first cavity 111, the second cavity 112, the third cavity 121 and the fourth cavity 122 increase successively from the fourth cavity 122 to the first cavity 111.

[0059] In this embodiment, the ejector tube 12 includes a third cavity 121 and a fourth cavity 122. The third cavity 121 and the fourth cavity 122 are interconnected, and the third cavity 121 is connected to the second cavity 112 via a through hole 1121, thereby interconnecting the first cavity 111, the second cavity 112, the third cavity 121, and the fourth cavity 122. The cross-sectional dimensions of the first cavity 111, the second cavity 112, the third cavity 121, and the fourth cavity 122 increase in order from the fourth cavity 122 to the first cavity 111, i.e., the size of the first cavity 111 is larger than the size of the second cavity 112, which is larger than the size of the third cavity 121, which is larger than the size of the fourth cavity 122.

[0060] A plurality of air inlets 1211 are provided on the outer wall of the third cavity 121 close to the fourth cavity 122, so that air can enter from the air inlet 1211, and a connecting thread 1221 is provided on the inner wall of the fourth cavity 122, so that the nozzle member 4 can be screwed. When the high-pressure gas is sprayed into the ejector pipe 12 from the nozzle member 4, it will successively enter the fourth cavity 122, the third cavity 121, the second cavity 112, and the first cavity 111 with increasing cross-sectional sizes. At the same time, the pressure difference will suck air from the air inlet 1211 of the third cavity 121. When the mixed gas in the third cavity 121 enters the second cavity 112 through the through hole 1121, it will be drawn in by the premixed gas above the through hole 1121. The regulating plate 6 blocks, so that most of the mixed gas is blocked and reflected into the third cavity 121, and the airflow produces vertical counter-collision, and the mixing uniformity is further improved. At the same time, the upward vertical airflow, that is, along the second cavity 122, changes its path due to the front blocking of the horizontal premixing regulating plate 6 and diffuses radially into the furnace cavity. The radial airflow hits the inner wall of the second cavity 122 and is partially reflected. The reflected rebound gas continues to counter-mix with the forward gas, and the mixed gas finally passes through the guide hole 62 and the gap between the premixing regulating plate 6 and the side wall of the second cavity 122 into the space between the flame stabilizing part 2 and the premixing regulating plate 6 (that is, in the second cavity 122), and finally reaches the surface of the flame stabilizing part 2 arranged in the first cavity 111.

[0061] Furthermore, a decorative ring 7 is provided on the flame stabilizing member 2, and the decorative ring 7 includes a first decorative ring 71 and a second decorative ring 72 connected to each other.

[0062] In this embodiment, the decorative ring 7 is mounted on the flame stabilizer 2 and includes a first decorative ring 71 and a second decorative ring 72. The first decorative ring 71 and the second decorative ring 72 are integrally formed. Specifically, the first decorative ring 71 is placed on the surface of the flame stabilizer 2, while the second decorative ring 72 is sleeved onto the outer wall of the first cavity 111 of the furnace body 11.

The positioning notch of the second decorative ring 72 matches the size of the positioning boss 113, allowing the second decorative ring 72 to downwardly wrap around the positioning boss 113. Two ignition ground electrodes 711 are disposed on the side of the first decorative ring 71 near the positioning notch, and an ignition positive electrode 31 is disposed between the two ignition ground electrodes 711, thereby enabling an arc to be generated between the ignition positive electrode 711 and the ignition positive electrode 31.

[0063] Among them, the ignition ground electrode 711 is set on the side close to the positioning notch to ensure that when the positioning notch is inserted on the positioning boss 113, the ignition positive electrode 31 can be exactly in the middle of the two ignition ground electrodes 711 on the first decorative ring 71 and ensure a reasonable discharge distance, and the discharge arc between the ignition ground electrode 711 and the ignition positive electrode 31 just passes horizontally through the inner flame of the flame stabilizing member 2.

[0064] Specifically, the positions of the ignition positive electrode 31 and the ignition ground electrode 711 are at the edge of the flame stabilizing member 2, thereby forming a position for atmospheric combustion, and when the ignition positive electrode 31 discharges, the spark passes through the inner flame of the flame, and the ignition success rate is very high. It successfully solves the problem of ignition failure caused by the high-speed airflow carrying away heat during cold ignition and the difficulty in reaching the ignition point of the gas.

[0065] Furthermore, a mounting hole 1123 is also provided on one side of the furnace body 11 where the through hole 1121 is provided, that is, the through hole 1121 and the mounting hole 1123 are arranged in the same plane, and the ignition element 3 is arranged in the furnace body 11 through the mounting hole 1123, and the ignition element 3 is connected to the ignition positive electrode 31 at one end close to the flame stabilizing element 2, and the tip of the ignition positive electrode 31 is exposed to the fire hole of the flame stabilizing element 2 so that an arc can be generated with the ignition ground electrode 711, and a wiring terminal 32 is provided at the other end, and the wiring terminal 32 is also exposed to the furnace body 11, so that the wiring terminal 32 can be connected to the piezoelectric ceramic element 8, and the piezoelectric ceramic element 8 can generate an instantaneous high voltage, so that the ignition positive electrode 31 and the ignition ground electrode 711 can generate two electric spark discharges of sufficient intensity.

[0066] The ignition positive electrode 31 is specifically an ignition needle.

[0067] Furthermore, the nozzle member 4 includes a nozzle seat 41, one side of the nozzle seat 41 is vertically screwed into the fourth cavity 122 and is also provided with a nozzle 42, and an air intake pipe mounting hole 431 is provided on the side of the nozzle seat 41 away from the fourth cavity 122, and an air pipe control valve assembly 5 is connected through the air intake pipe mounting hole 431.

Alternatively, dedicated control valves for other gas sources can be used. The gas enters the nozzle holder 41 through the gas pipe control valve assembly 5 and is ejected vertically upward through the nozzle 42 connected to the nozzle holder 41 into the fourth cavity 122 of the ejector tube 12, and then vertically upward until it reaches the surface of the flame stabilizer 2.

[0069] Furthermore, a first step 123 is provided on the outer wall of the ejector tube 12 close to the nozzle seat 41, and a first positioning plane 1231 and a first mounting thread 1232 are also provided on the outer wall of the ejector tube 12 close to the first step 123; a second step 124 is also provided on the side of the ejector tube 12 close to the furnace body 11, and a second positioning plane 1241 and a second mounting thread 1242 are also provided on the outer wall of the ejector tube 12 close to the second step 124.

[0070] In this embodiment, the ejector tube 12 is provided with a first step 123 and a second step 124 from bottom to top, and a first positioning plane 1231 and a first mounting thread 1232 are provided on the outer wall of the ejector tube 12 at a position below the first step 123, and a second positioning plane 1241 and a second mounting thread 1242 are provided on the outer wall of the ejector tube 12 at a position below the second step 124. The first mounting thread 1232, the second mounting thread 1242 and the first positioning plane 1231 and the second positioning plane 1241 are respectively provided on both sides of the ejector tube 12, and the first positioning plane 1231 and the second positioning plane 1241 are provided close to one side of the mounting hole 1123 connected to the ignition component 3.

[0071] Among them, there are two levels of first steps 123 and second steps 124. The first step 123 is arranged on the side of the ejector tube 12 close to the nozzle part 4, and the second step 124 is arranged on the side of the ejector tube 12 close to the furnace body 11, just located at the upper and lower ends of the outer wall of the ejector tube 12, and the first mounting thread 1232 and the second mounting thread 1242 below the first step 123 and the second step 124 are two different specifications. The nominal diameter of the first mounting thread 1232 is smaller than the nominal diameter of the second mounting thread 1242, so that the burner can be suitable for installation applications on grate racks of different structures, making the application range of the burner wider.

[0072] Furthermore, it also includes a multi-axis folding furnace rack 9, in which the combustion element 1 is inserted. The multi-axis folding furnace rack 9 includes a base 91 and multiple support assemblies 92. The multiple support assemblies 92 are evenly connected to the base 91 through a second connecting member 93. Each support assembly 92 rotates relative to the base 91 through the corresponding second connecting member 93, so that the support assembly 92 can unfold and support the base 91 or fold and retract on the base 91; a combustion element mounting hole 911 and an air avoidance hole 912 are provided on the base 91, the ejector tube 12 is inserted in the combustion element mounting hole 911, the ignition element 3 is arranged in the air avoidance hole 912, the first step 123 abuts against the base 91, and a positioning straight edge 9111 is provided in the combustion element mounting hole 911, and the positioning straight edge 9111 is adapted to the first positioning plane 1231.

[0073] In this embodiment, the combustion element 1 is inserted into the multi-axis folding furnace frame 9, which includes a base 91 and a plurality of support assemblies 92. The plurality of support assemblies 92 are evenly spaced and connected to the base 91. Specifically, the plurality of support assemblies 92 is 4 in this embodiment, and the support assemblies 92 are spaced 90° apart from each other.

[0074] Specifically, each support assembly 92 is connected to the base 91 through a second connecting member 93, and each support assembly 92 can rotate relative to the base 91 through the second connecting member 93, wherein a rotation limit hole 913 is also provided on the base 91. When the support assembly 92 rotates relative to the base 91, the support assembly 92 will drive the second connecting member 93 to rotate in the rotation limit hole 913, thereby allowing the support assembly 92 to be unfolded or folded relative to the base 91. When multiple support assemblies 92 are unfolded relative to the base 91, stoves can be placed on multiple support assemblies 92. After the stove is used, the multiple support assemblies 92 are rotated in the opposite direction relative to the base 91, so that the multiple support assemblies 92 are folded and stored on the base 91. A plurality of support components 92 are provided on the base 91, which can be unfolded for use or folded for storage by rotation, so that the multi-axis folding stove rack has a small folding volume, a large unfolding support surface, and a stable structure. The unfolding and folding are simple and convenient, and it is suitable for use in various outdoor scenes. In addition, the multi-axis folding stove rack 9 has a simple structure and low manufacturing cost, and is suitable for large-scale promotion and use.

[0075] Specifically, support assembly 92 includes a support member 921 and a bracket member 922. Both support members 921 and bracket member 922 face vertically upward. Support member 921 is used to support the ground. Multiple support members 921 of the support assembly can support the multi-axis folding stove on the ground. Bracket member 922 is used to support the stove, which can be placed on the bracket members 922 of the support assembly. Second connecting member 93 includes a first right-angled side and a second right-angled side. The first right-angled side is rotatably connected to base 91. Support member 921 and bracket member 922 are connected to either side of the second right-angled side via a rivet. Support member 921 and bracket member 922 can rotate relative to each other, allowing support member 921 and bracket member 922 to move closer to or further away from base 91.

[0076] The adjacent ends of the support member 921 and the bracket member 922 are rotatably connected to the second connecting member 93, and the opposite ends are used to support the ground and support the stove respectively. When the opposite ends of the two move in the direction away from the base 91, the end of the support member 921 and the bracket member 922 adjacent to the support member 921 will abut against the base 91, and the end of the bracket member 922 adjacent to the support member 921 will be inserted into the positioning hole 914, so that the support member 921 and the bracket member 922 can be more stable.

[0077] When the support assembly 92 rotates relative to the base 91, the support member 921 and the bracket member 922 can be relatively unfolded or folded. When the support member 921 and the support frame 922 are unfolded, the support member 921 is used to support the ground, and the bracket member 922 is used to support the stove, so that the combustion member 1 can be used.

[0078] In this embodiment, a combustion component mounting hole 911 and an air-avoiding hole 912 are provided on the base 91 . The ejector tube 12 is inserted into the combustion component mounting hole 911 , and the ignition component 3 is provided in the air-avoiding hole 912 .

[0079] In this embodiment, the first step 123 of the ejector tube 12 is arranged in the multi-axis folding furnace frame 9. Specifically, the ejector tube 12 is inserted into the combustion component mounting hole 911, the first step 123 is tightly attached to the base 91, and the first positioning plane 1231 is in contact with the positioning straight edge 9111 in the combustion component mounting hole 911, so that the ignition component 3 can be coaxial with the air avoidance hole 912.

[0080] Furthermore, the ejector tube 12 is connected to a trachea directing plate 10 provided with a trachea air-avoiding gap 101, a fixing part 125 is connected to the first mounting thread 1232, and the trachea directing plate 10 is abutted against the base 91 through the fixing part 125, and an adjusting part 126 is also connected to the first mounting thread 1232, and the adjusting part 126 is also connected to the nozzle seat 41 to drive the air inlet pipe mounting hole 43 on the nozzle seat 42 41 to correspond to the trachea air-avoiding gap 101.

[0081] In this embodiment, the trachea directing plate 10 is arranged on the ejector tube 12, and the trachea directing plate 10 is fixed to the bottom of the combustion component mounting hole 911 by a fixing part 125 screwed on the first mounting thread 1232, so that the combustion component 1 can be firmly fixed while protecting the ignition component 3 from being broken by the torque generated by the arbitrary rotation of the thread.

[0082] An adjusting member 126 is also threadedly connected to the first mounting thread 1232. The adjusting member 126 is also connected to the nozzle holder 41. When the nozzle holder 41 is threadedly adjusted, the air intake pipe mounting hole 43 can be aligned with the air intake air gap 101. This allows the air intake control valve assembly 5 to be installed in the air intake pipe mounting hole 43 and pass through the air intake air gap 101. The air intake mounting plate 10 includes a vertical folded edge, and the air intake air gap 101 is provided on the vertical folded edge.

[0083] Furthermore, the specific working steps of the direct-injection high-heat-intensity blue-light infrared gas burner are as follows:

[0084] When the gas appliance needs to be used, the support assembly 92 on the multi-axis folding stove frame 9 is first rotated relative to the base 91 , so as to be unfolded relative to the base 91 and support the base 91 .

[0085] At this time, the high-pressure gas enters the nozzle 41 from the gas pipe control valve assembly 5. When the high-pressure gas is sprayed into the ejector pipe 12 through the nozzle 41, the pressure difference is used to suck air from the air inlet 1211 perpendicular to the gas flow direction. The high-pressure gas and air are mixed in the ejector pipe 12 and the furnace body 11. When passing through the ejector pipe 12 and entering the furnace body 1, the front of the premixing adjustment plate 6 arranged above the ejector pipe 12 will block most of the mixed gas, and it cannot enter the furnace body 11 and can only be reflected into the ejector pipe 12. The air flow produces a vertical collision, and the uniformity of the mixed gas in the ejector pipe 12 is further improved. At the same time, the air flow from the ejector pipe 12 upward vertically, that is, along the axial direction of the furnace body 11, is blocked by the front of the premixing adjustment plate 6 and changes its path to flow and diffuse in the radial direction of the furnace body 11. The radial gas After the flow hits the inner wall of the furnace body 11, it is partially reflected, and the reflected and rebounded gas continues to collide and mix with the forward gas. The mixed gas finally enters the space between the flame stabilizing part 2 and the premixing adjustment plate 6 through the gap between the premixing adjustment plate 6 and the inner wall of the furnace body 11, and finally forms a uniform combustible gas through the homogenization effect of the mutual interpenetration of the flame stabilizing part 2 and each mixed airflow to reach the surface of the flame stabilizing part 2. The gas is ignited by the electric arc through the ignition positive electrode 31 of the ignition part 3 built into the furnace body 11 and the ignition ground electrode 711 on the surface of the flame stabilizing part 2, and most of the gas is distributed in most of the area in the middle area of ​​the flame stabilizing part 2 to form infrared combustion, and atmospheric combustion with a blue flame and micro-flame is formed at the outer edge, thereby realizing efficient combustion and high thermal intensity of the burner, effectively reducing the volume of the burner and making it more portable.

[0086] As can be seen from the above, the beneficial effects of this embodiment are as follows:

[0087] Firstly, the combustion element 1 has a high thermal intensity, which is several times higher than that of the infrared burners in the prior art, and has a large adjustment range and a wide range of application scenarios.

[0088] Secondly, for the first time, the same burner has achieved a composite combustion mode with infrared as the main combustion mode and atmospheric combustion as the auxiliary combustion mode. It inherits the advantages of infrared such as excellent wind resistance and high thermal efficiency, and has the advantage of atmospheric combustion being easier to ignite.

[0089] Third, the discharge position of the built-in ignition positive electrode 31 and the ignition ground electrode 711 is exactly located at the edge of the flame stabilizing member 2 to form atmospheric combustion, and when the ignition positive electrode 31 discharges, the spark passes through the inner flame of the flame, and the ignition success rate is very high. It successfully solves the problem of ignition failure caused by the high-speed airflow carrying away heat during cold ignition and the difficulty in reaching the ignition point of the gas.

[0090] Fourth, in vertical direct injection combustion, the end face of the nozzle member 4 is vertically far away from the high-temperature plane of the flame stabilizing member 2, and there is an air inlet 1211 near the nozzle member 4. The cold air continuously cools, so the temperature rise is low, which minimizes the risk of flashback.

[0091] Fifth, an outdoor fuel appliance is provided that has a small folding volume, a large supporting surface when unfolded, and a stable structure. It is simple and convenient to unfold and fold, and is suitable for use in various outdoor scenes.

[0092] Sixth, the burning appliance has a simple structure and low manufacturing cost, making it suitable for large-scale promotion and use.

[0093] Seventh, the CO content in flue gas emissions is low, making it safe and environmentally friendly to use.

[0094] Eighth, the wind resistance is one step further than that of traditional infrared burners. It can achieve stronger wind resistance while maintaining a good combustion state, ensuring that the heating performance in outdoor strong wind environments is basically not deteriorated.
