Description

Technical Field

[0001] The present invention relates to the technical field of gas combustion, and particularly 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 well-known due to their high popularity rate. In recent years, infrared burners have received increasing attention due to their high efficiency, energy conservation, environmental protection, and low-carbon characteristics. However, at present, the volume of infrared burners is too large, the structure is relatively complex, and the manufacturing cost is much higher than that of atmospheric gas appliances, which greatly limits their popularization and application. It is reported that the popularization rate of current infrared household stoves is only 3%, and there is a great market prospect. Therefore, it is extremely necessary to develop an infrared burner with a small volume, simple structure, and high heat intensity. Secondly, the frequency of people's outdoor camping activities shows a significant increasing trend, and the demand for outdoor gas appliances has increased sharply. However, current outdoor infrared gas appliances still cannot well meet the user experience, mainly manifested in the following points:

[0003] 1. The heat intensity is low. To increase the heat load to meet the fast heat dissipation environment of outdoor cooking, it is necessary to increase the flame hole area of the burner. Therefore, outdoor stoves need a larger volume, but the large volume poses great challenges to cost control and portability.

[0004] 2. Currently, the area heat intensity of household gas infrared burners is about 140 - 200 kW / ㎡, and the highest heat intensity of outdoor infrared cartridge stoves is about 300 kW / ㎡. This means that according to the above heat intensity, to achieve a moderate heat load of 3 kW for outdoor applications, the size of the effective combustion surface of the burner is about Φ113 - Φ165, and the size of the burner is about Φ123 - Φ175. Considering the setting of the stove size, this area is unacceptable for outdoor gas appliances.

[0005] 3. High-heat-intensity infrared burners are prone to flashback, especially in the field of high-pressure outdoor camping stoves, where the gas pressure is often as high as one hundred thousand or even one million Pa. Moreover, due to the influence of gas consumption and gasification cooling of disposable gas cylinders, the pressure fluctuates greatly. To manufacture a high-heat-intensity infrared burner under the premise of extremely large gas pressure fluctuations and prevent flashback, the conventional structure is relatively complex, and the height of the burner furnace cavity also needs to be increased, so the volume is also large.

[0006] 4. High heat intensity means that more gas combustion reactions are completed per unit flame hole area, which means that the probability of incomplete gas combustion increases, resulting in a sharp rise in the CO concentration in the flue gas. A large change in gas pressure will also cause the deterioration of working conditions at certain pressures, resulting in an increase in CO.

[0007] 5. High heat intensity and a small head area will cause a sharp increase in gas flow velocity. During cold ignition, the high-speed airflow will carry away heat, making it difficult to reach the ignition point of the gas and resulting in ignition failure. The existing technology usually uses a standing pilot or adds an atmospheric ignition burner to achieve ignition, but this is not very friendly to the volume and cost of the stove.

[0008] 6. Although the current product's wind resistance performance meets the technical standards and has good effects, it cannot compensate for the deterioration of heating performance and ignition performance caused by strong outdoor winds. Moreover, even adding windproof components will increase more 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 and infrared gas appliance, including:

[0042] A combustion member 1, the combustion member 1 includes a furnace body 11 and an ejector tube 12 that are connected to each other. A premixing adjustment plate 6 adapted thereto is fixedly connected inside the furnace body 11, and a plurality of air inlets 1211 are provided on the ejector tube 12;

[0043] A flame stabilizing member 2, 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, and an ignition ground electrode 711 is also arranged on the flame stabilizing member 2;

[0044] An ignition member 3, the ignition member 3 is arranged inside the furnace body 11, and the ignition member 3 further includes an ignition positive electrode 31. The ignition positive electrode 31 is arranged through and exposed outside the flame stabilizing member 2, and the ignition positive electrode 31 and the ignition ground electrode 711 are arranged close to each other;

[0045] A nozzle member 4, 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 member 1 includes a furnace body 11 and an ejector tube 12 that are connected to each other. The connection manner between the furnace body 11 and the ejector tube 12 is integrally formed, and the connection manner between the furnace body 11 and the ejector tube 12 is not limited herein and is set according to the actual production method.

[0047] In this embodiment, a flame stabilizing member 2 is provided at one end of the furnace body 11 away from the ejector tube 12. The size of the flame stabilizing member 2 is adapted to the size of the furnace body 11, so that the flame stabilizing member 2 can be fixedly connected inside the furnace body 11. An ignition member 3 is also provided inside the furnace body 11. An ignition positive electrode 31 is provided on the ignition member 3. The ignition positive electrode 31 penetrates through the flame stabilizing member 2 and is exposed outside the flame stabilizing member 2. An ignition ground electrode 711 is also provided on the flame stabilizing member 2. The ignition ground electrode 711 and the ignition positive electrode 31 are arranged close to each other, so that a discharge can occur between the ignition ground electrode 711 and the ignition positive electrode 31 to ignite the combustible mixed gas that sequentially flows from the ejector tube 12 to the furnace body 11 and then reaches the surface of the flame stabilizing member 2. One end of the ejector tube 12 away from the furnace body 11 is also connected to a nozzle member 4, so that high-pressure gas can be vertically sprayed upward into the ejector tube 12 from the nozzle member 4. Among them, the ignition ground electrode 711 is a grounded electrode.

[0048] Specifically, a premixing adjustment plate 6 is fixedly connected inside the furnace body 1. The premixing adjustment plate 6 is arranged above the ejector tube 12. A plurality of air inlets 1211 are provided on the ejector tube 12. When the high-pressure gas is sprayed into the ejector tube 12, air is sucked in from the air inlets 1211 perpendicular to the direction of the gas flow by using the pressure difference. The high-pressure gas and air are mixed in the ejector tube 12 and the furnace body 11. When passing through the ejector tube 12 and entering the furnace body 11, the front surface of the premixing adjustment plate 6 arranged above the ejector tube 12 will block most of the mixed gas, preventing it from entering the furnace body 11 and only reflecting it into the ejector tube 12, resulting in a vertical counterflow of the air flow. The uniformity of the mixed gas in the ejector tube 12 is further improved. At the same time, the air flow that is vertically upward along the axis of the furnace body 11 from the ejector tube 12 changes its path and flows and diffuses in the radial direction of the furnace body 11 due to the blockage of the front surface of the premixing adjustment plate 6. The radial air flow collides with the inner side wall of the furnace body 11 and generates partial reflection. The reflected and rebounded gas continues to generate counterflow mixing with the advancing gas. The mixed gas finally enters 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 side wall of the furnace body 11. Finally, through the homogenizing effect of the mutual interpenetration of the flame stabilizing member 2 and each mixed air flow, a uniform combustible gas reaches the surface of the flame stabilizing member 2. That is, the premixing adjustment function of the premixing adjustment plate 6 is equivalent to extending the path of diffusion mixing, enabling the gas and air to be more fully mixed, greatly shortening the length of the ejector tube 12, reducing the size of the end of the furnace body 11 where the flame stabilizing member 2 is provided, and greatly reducing the overall volume, thereby greatly improving the thermal intensity.

[0049] Specifically, high-pressure gas is vertically sprayed upward from the nozzle member 4 into the ejector tube 12. By using the pressure difference, air is sucked in from the air inlet 1211 which is 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 then vertically enter the furnace chamber 11. The premix adjustment plate 6 fixed inside the furnace chamber 11 extends the premix path and adjusts the distribution of the mixed gas, effectively shortening the axial length of the ejector tube 12 and the radial dimension of the furnace chamber 11, efficiently forming a uniform combustible mixed gas, and reaching the surface of the flame stabilizer 2 at the head of the furnace body 11. At the same time, the air flow at the edge part is slightly greater than that in the middle. The ignition positive electrode 31 of the ignition member 3 built in the furnace body 11 and the ignition ground electrode 711 on the surface of the flame stabilizer 2 ignite the gas through an electric arc, distributing most of the gas in most of the area in the middle region of the flame stabilizer 2 to form infrared combustion, and forming atmospheric combustion with blue flame microflames at the outer edge part, thereby realizing the efficient combustion and high heat intensity of the burner, effectively reducing the volume of the gas appliance and making it more portable.

[0050] Among them, the nozzle member 4 is vertically arranged below the ejector tube 12, enabling the high-pressure gas to be vertically sprayed into the ejector tube 12 through the nozzle member 4. The nozzle member 4 is vertical and far away from the high-temperature plane of the flame stabilizer 2, and an air inlet 1211 is also provided at the ejector tube 12, enabling the nozzle member 4 to be continuously cooled, so the temperature rise is relatively low, minimizing the risk of flashback.

[0051] Furthermore, the furnace body 11 includes a first cavity 111 and a second cavity 112 that are connected. A through hole 1121 is opened at the central position on the side of the second cavity 112 close to 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 premix adjustment plate 6. A plurality of first connectors 1122 are evenly distributed around the through hole 1121, and are connected to a plurality of support members 61 on the premix adjustment plate 6 through the plurality of first connectors 1122. A plurality of diversion holes 62 are evenly distributed at the edge of the premix 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 dimension of the first cavity 111 is larger than that of the second cavity 112. A through hole 1121 is provided on one side of the second cavity 112 close to the ejector tube 12, and the second cavity communicates with the ejector tube 12 through this 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 provided at the central axis position of the second cavity 112, and a plurality of first connectors 1122 are evenly distributed around the through hole 1121. Above the first connectors 1122, there is a premixing adjustment plate 6 adapted to the shape of the furnace cavity 11. A plurality of support members 61 are evenly provided on the bottom of the premixing adjustment plate 6, and are connected to the first connectors 1122 through the plurality of support members 61, so that the premixing adjustment plate 6 is fixedly connected inside the furnace body 11, that is, the central position of the premixing adjustment plate 6 is also the position of the through hole 1121.

[0053] Specifically, a plurality of evenly distributed diversion holes 62 are also provided at the edge part of the premixing adjustment plate 6, and no diversion holes are provided in the middle part above the through hole 1121. When the mixed gas in the ejector tube 12 is 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 side 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 diversion holes 62 provided on the premixing adjustment plate 6. Finally, through the homogenizing effect of the mutual interpenetration of the flame stabilizing member 2 and each mixed gas flow, a uniform combustible gas reaches the surface of the flame stabilizing member 2 and is ignited by the arc generated between the ignition positive electrode 31 and the ignition ground electrode 711.

[0054] Among them, the number of the first connectors 1122 and the support members 61 is the same, and both are 4 in this embodiment, and the first connectors 1122 are specifically rivets.

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

[0056] In this embodiment, a plurality of flame holes are provided on the flame stabilizer 2, and a support step 1111 is provided on the inner side wall of the first cavity 111. The flame stabilizer 2 is closely mounted on the support step 1111. The support step 1111 is a flat horizontal plane, and the size of the flame stabilizer 2 is adapted to the cross-sectional size of the first cavity 111, so that the flame stabilizer 2 can be in close contact with the inner side wall of the first cavity 111, thereby ensuring the sealing of the flame stabilizer 2 and ensuring that the mixed combustible gas will not leak out from the side of the flame stabilizer 2, and will only reach the head surface of the burner 1 through the flame holes of the flame stabilizer 2.

[0057] Among them, the size of the flame holes on the flame stabilizer 2 is slightly larger than the size of the ignition positive electrode 31, so that the ignition positive electrode 31 can penetrate through the flame holes and be exposed outside the flame holes. Since the ignition ground electrode 711 is provided on the flame stabilizer 2, it is necessary to expose the ignition positive electrode 31 outside the flame holes, so that an electric 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 stabilizer 2. Moreover, the material used for the flame stabilizer 2 in this embodiment is a porous insulating refractory material, which is a non-conductive insulating material and also a refractory material, and 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 and communicated. A connecting thread 1221 for connecting the nozzle member 4 is provided on the inner side wall of the fourth cavity 122. The third cavity 121 is communicated with the second cavity 112 through a through hole 1121. A plurality of air inlets 1211 are penetrated and opened on the outer wall of the third cavity 121 close to the fourth cavity 122. The first cavity 111, the second cavity 112, the third cavity 121, and the fourth cavity 122 are interconnected, and the cross-sectional sizes of the first cavity 111, the second cavity 112, the third cavity 121, and the fourth cavity 122 increase in sequence 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, and the third cavity 121 and the fourth cavity 122 are connected and communicated. Moreover, the third cavity 121 is communicated with the second cavity 112 through a through hole 1121, so that the first cavity 111, the second cavity 112, the third cavity 121, and the fourth cavity 122 are interconnected. Among them, the cross-sectional sizes of the first cavity 111, the second cavity 112, the third cavity 121, and the fourth cavity 122 increase in sequence from the fourth cavity 122 to the first cavity 111, that is, the size of the first cavity 111 is larger than the size of the second cavity 112, the size of the second cavity 112 is larger than the size of the third cavity 121, and the size of the third cavity 121 is larger than the size of the fourth cavity 122.

[0060] A plurality of air inlets 1211 are formed through the outer wall of the third cavity 121 close to the fourth cavity 122, so that air can enter from the air inlets 1211. A connecting thread 1221 is provided on the inner side wall of the fourth cavity 122, so that the nozzle member 4 can be screwed. When high-pressure gas is sprayed into the injection pipe 12 from the nozzle member 4, it will sequentially enter the fourth cavity 122, the third cavity 121, the second cavity 112, and the first cavity 111 with the cross-sectional size increasing in sequence. At the same time, the pressure difference will suck air from the air inlets 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 blocked by the premixing adjustment plate 6 above the through hole 1121, so that most of the mixed gas is blocked and reflected into the third cavity 121, and the air flow generates a vertical counterflow, further improving the mixing uniformity. At the same time, the upward vertical air flow along the second cavity 122 changes its path and flows radially into the furnace cavity due to the frontal block of the horizontal premixing adjustment plate 6. The radial air flow collides with the inner side wall of the second cavity 122 and generates partial reflection. The reflected and rebounded gas continues to generate counterflow mixing with the forward gas. Finally, the mixed gas enters the space between the flame stabilizing member 2 and the premixing adjustment plate 6 (i.e., inside the second cavity 122) through the diversion holes 62 and the gap between the premixing adjustment plate 6 and the side wall of the second cavity 122, and finally reaches the surface of the flame stabilizing member 2 arranged in the first cavity 111.

[0061] Furthermore, a decorative ring 7 is also covered on the flame stabilizing member 2. The decorative ring 7 includes a first decorative ring 71 and a second decorative ring 72 connected to each other. The first decorative ring 71 is arranged on the flame stabilizing member 2, and the second decorative ring 72 is sleeved on the outer side wall of the furnace body 11. A positioning notch is formed on the side of the second decorative ring 72 away from the first decorative ring 71. A positioning boss 113 is provided on the outer side wall of the furnace body 11, and the positioning notch is adaptively inserted on the positioning boss 113. Two ignition ground electrodes 711 are arranged at intervals on the side of the first decorative ring 71 close to the positioning notch. An ignition positive electrode 31 is also arranged between the two ignition ground electrodes 711, and the ignition positive electrode 31 and the two ignition ground electrodes 711 are respectively arranged at the edge of the flame stabilizing member 2.

[0062] In this embodiment, the decorative ring 7 is covered on the flame stabilizing member 2, and the decorative ring 7 includes a first decorative ring 7 and a second decorative ring 72. The first decorative ring 71 and the second decorative ring 72 are connected in an integrally formed manner. Specifically, the first decorative ring 71 is placed on the surface of the flame stabilizing member 2, and the second decorative ring 72 is sleeved on the outer wall of the first cavity 111 of the furnace body 11. A positioning notch is also provided at the bottom of the second decorative ring 72, and a positioning boss 113 is also provided on the outer wall of the first cavity 111. The positioning notch of the second decorative ring 72 is adapted to the size of the positioning boss 113, so that the second decorative ring 72 can wrap around the positioning boss 113 downward. Among them, two ignition ground electrodes 711 arranged at intervals are also provided on the side of the first decorative ring 71 close to the positioning notch, and an ignition positive electrode 31 is also provided between the two ignition ground electrodes 711, so that an arc can be generated between the ignition positive electrode 711 and the ignition positive electrode 31.

[0063] Among them, the ignition ground electrode 711 is arranged 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 horizontally passes 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 just passes through the inner flame of the flame, and the ignition success rate is very high. This successfully solves the problem of ignition failure caused by the high-speed airflow taking away heat during cold ignition and it is difficult to reach 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 component 3 is arranged in the furnace body 11 through the mounting hole 1123, and the ignition component 3 is connected to the ignition positive electrode 31 at one end close to the flame stabilizing component 2, and the tip of the ignition positive electrode 31 is exposed to the fire hole of the flame stabilizing component 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 component 8, and the piezoelectric ceramic component 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] Further, the nozzle member 4 includes a nozzle base 41. One side of the nozzle base 41 is vertically screwed into the fourth cavity 122 and is also provided with a nozzle 42. On the side of the nozzle base 41 away from the fourth cavity 122, an air inlet pipe mounting hole 431 is provided, and an air pipe control valve assembly 5 is connected through the air inlet pipe mounting hole 431.

[0068] In this embodiment, the air pipe control valve assembly 5 can be connected to an alpine air pipe, can also be equipped with an adapter to connect to other air sources, or can also use a special control valve for other air sources. The air source enters the nozzle base 41 through the air pipe control valve assembly 5, and is vertically sprayed upward into the fourth cavity 122 of the injection pipe 12 through the nozzle 42 connected to the nozzle base 41, and vertically upward until it reaches the surface of the flame stabilizing member 2.

[0069] Further, a first step 123 is provided on the outer side wall of the injection pipe 12 close to the nozzle base 41. A first positioning plane 1231 and a first mounting thread 1232 are also provided on the outer side wall of the injection pipe 12 close to the first step 123; a second step 124 is also provided on the side of the injection pipe 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 side wall of the injection pipe 12 close to the second step 124.

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

[0071] Among them, two levels of horizontal first steps 123 and second steps 124 are provided here. The first step 123 is provided on the side of the injection pipe 12 close to the nozzle member 4, and the second step 124 is provided on the side of the injection pipe 12 close to the furnace body 11, exactly at the upper and lower ends of the outer side wall of the injection pipe 12. The first mounting thread 1232 and the second mounting thread 1242 below the first step 123 and the second step 124 are of 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 the installation and application of furnace racks with different structures, and the application range of the burner is wider.

[0072] Further, it further includes a multi-axis folding stove rack 9. The combustion member 1 is inserted into the multi-axis folding stove rack 9. The multi-axis folding stove rack 9 includes a base 91 and a plurality of support components 92. The plurality of support components 92 are respectively and evenly connected to the base 91 through a second connecting member 93. Each support component 92 makes a rotational movement relative to the base 91 through the corresponding second connecting member 93, so that the support component 92 unfolds to support the base 91 or folds and retracts onto the base 91. A combustion member mounting hole 911 and a clearance hole 912 are formed on the base 91. The ejector pipe 12 is inserted into the combustion member mounting hole 911, and the ignition member 3 is arranged in the clearance hole 912. The first step 123 abuts against the base 91. A positioning straight edge 9111 is arranged in the combustion member mounting hole 911, and the positioning straight edge 9111 is adapted to the first positioning plane 1231.

[0073] In this embodiment, the combustion member 1 is inserted into the multi-axis folding stove rack 9. The multi-axis folding stove rack 9 includes a base 91 and a plurality of support components 92. The plurality of support components 92 are evenly spaced and connected to the base 91. Among them, the plurality of support components 92 are specifically 4 in this embodiment, and the interval between two adjacent support components 92 is set at 90°.

[0074] Specifically, each support component 92 is connected to the base 91 through a second connecting member 93, and each support component 92 can make a rotational movement relative to the base 91 through the second connecting member 93. Among them, a rotational limit hole 913 is further formed on the base 91. When the support component 92 makes a rotational movement relative to the base 91, the support component 92 will drive the second connecting member 93 to rotate in the rotational limit hole 913, so that the support component 92 unfolds or folds relative to the base 91. When the plurality of support components 92 all unfold relative to the base 91, a cooking appliance can be placed on the plurality of support components 92. After the cooking appliance is used, the plurality of support components 92 are rotated in the reverse direction relative to the base 91, so that the plurality of support components 92 are folded and retracted onto the base 91. By arranging a plurality of support components 92 on the base 91 that can be unfolded for use or folded and stored by rotation, the multi-axis folding stove rack plays the role of small folding volume, large unfolding support surface and stable structure. The unfolding and folding are simple and convenient, suitable for various outdoor scenarios. Moreover, the structure of the multi-axis folding stove rack 9 is simple and the manufacturing cost is low, which is suitable for large-scale popularization and use.

[0075] Specifically, the support assembly 92 includes a support member 921 and a bracket member 922. The planes of the support member 921 and the bracket member 922 are both vertically upward. The support member 921 is used to support the ground, and the support members 921 of multiple support assemblies can support the multi-axis folding stove rack on the ground. The bracket member 922 is used to support the cooking appliance, and the cooking appliance can be placed on the bracket members 922 of multiple support assemblies. The second connecting member 93 includes a first right-angle side and a second right-angle side. The first right-angle side is rotatably connected to the base 91. The support member 921 and the bracket member 922 are connected to both sides of the second right-angle side by a rivet, and the support member 921 and the bracket member 922 can rotate relative to each other, so that the support member 921 and the bracket member 922 can approach or move away from the base 91 relative to each other.

[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 respectively used to support the ground and the cooking appliance. When the opposite ends of the two move away from the base 91 respectively, the adjacent ends of the support member 921 and the bracket member 922 will abut against the base 91, and the adjacent end of the bracket member 922 and 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 cooking appliance, so that the combustion member 1 can be used.

[0078] In this embodiment, a combustion member installation hole 911 and a clearance hole 912 are provided on the base 91. The injection pipe 12 is inserted into the combustion member installation hole 911, and the ignition member 3 is arranged in the clearance hole 912.

[0079] In this embodiment, the first step 123 of the injection pipe 12 is arranged in the multi-axis folding stove rack 9. Specifically, the injection pipe 12 is inserted into the combustion member installation hole 911, and the first step 123 is closely attached to the base 91, and the first positioning plane 1231 is fitted with the positioning straight edge 9111 in the combustion member installation hole 911, so that the ignition member 3 can be coaxial with the clearance hole 912.

[0080] Furthermore, the injection pipe 12 is connected with an air pipe orientation plate 10 provided with an air pipe clearance notch 101. A fixing member 125 is connected to the first installation thread 1232, and the air pipe orientation plate 10 is abutted against the base 91 through the fixing member 125. An adjusting member 126 is also connected to the first installation thread 1232, and the adjusting member 126 is also connected to the nozzle seat 41 to drive the intake pipe installation hole 43 on the nozzle 42 seat 41 to correspond to the air pipe clearance notch 101.

[0081] In this embodiment, the trachea orientation plate 10 is arranged on the ejector pipe 12, and the trachea orientation plate 10 is fixedly arranged at the bottom of the burner mounting hole 911 through a fixing member 125 screwed onto the first mounting thread 1232, so that while firmly fixing the burner 1, the ignition member 3 can be protected from being broken by the torque generated by the random rotation of the thread.

[0082] An adjusting member 126 is also screwed onto the first mounting thread 1232, and the adjusting member 126 is also connected to the nozzle seat 41. When the nozzle seat 41 is driven to be adjusted by thread, the intake pipe mounting hole 43 can be aligned with the trachea clearance notch 101, and then the trachea control valve assembly 5 can be installed into the intake pipe mounting hole 43 and can pass through the trachea clearance notch 101. Among them, the trachea mounting plate 10 includes a vertical folding edge, and the trachea clearance notch 101 is arranged on the vertical folding edge.

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

[0084] When the gas appliance needs to be used, first rotate the support assembly 92 on the multi-axis folding furnace rack 9 relative to the base 91, so as to expand relative to the base 91 and support the base 91.

[0085] At this time, high-pressure gas enters the nozzle 41 from the trachea control valve assembly 5. When the high-pressure gas is sprayed into the ejector pipe 12 through the nozzle 41, air is sucked in from the air inlet 1211 in the direction perpendicular to the gas flow direction by using the pressure difference. The high-pressure gas and air are mixed in the ejector pipe 12 and the furnace body 11. When entering the furnace body 1 through the ejector pipe 12, the front surface of the premixing adjustment plate 6 arranged above the ejector pipe 12 will block most of the mixed gas and cannot enter the furnace body 11, but can only be reflected into the ejector pipe 12, and the air flow generates a vertical counterflush, further improving the uniformity of the mixed gas in the ejector pipe 12. At the same time, the air flow vertically upward from the ejector pipe 12, that is, along the axial direction of the furnace body 11, changes its path and flows and diffuses in the radial direction of the furnace body 11 due to the blocking of the front surface of the premixing adjustment plate 6. The radial air flow collides with the inner side wall of the furnace body 11 and generates partial reflection. The reflected and rebounded gas continues to generate counterflush and mixing with the forward gas. Finally, the mixed gas enters 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 side wall of the furnace body 11. Finally, through the homogenization effect of the mutual interpenetration of the flame stabilizing member 2 and each mixed air flow, a uniform combustible gas reaches the surface of the flame stabilizing member 2, and the gas is ignited by an electric arc between the ignition positive electrode 31 of the ignition member 3 built in the furnace body 11 and the ignition ground electrode 711 on the surface of the flame stabilizing member 2. Most of the gas is distributed in most of the area in the middle region of the flame stabilizing member 2 to form infrared combustion, and atmospheric combustion with blue flame microflames is formed at the outer edge part, so as to realize the efficient combustion and high heat intensity of the burner, effectively reduce the volume of the gas appliance and make it more portable.

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

[0087] First of all, the combustion piece 1 has a high thermal intensity, which is several times higher than that of the infrared burner in the prior art, and has a large adjustment range, so the application scenarios are wide.

[0088] Secondly, for the first time, the combustion mode of the same burner is a composite mode of mainly infrared and supplemented by atmospheric combustion, inheriting the advantages of excellent wind resistance and high thermal efficiency of infrared, and also having the advantage of easier ignition of atmospheric combustion.

[0089] Thirdly, the discharge position of the built-in ignition positive electrode 31 and the ignition ground electrode 711 is exactly at the edge of the flame stabilizing piece 2 where atmospheric combustion can be formed, and when the ignition positive electrode 31 discharges, the spark just passes through the inner flame of the flame, so the ignition success rate is very high, successfully solving the problem that ignition failure may occur during cold-state ignition because the high-speed air flow takes away heat and it is difficult to reach the ignition point of the gas.

[0090] Fourthly, for vertical direct injection combustion, the end face of the nozzle piece 4 is at a far vertical distance from the high-temperature plane of the flame stabilizing piece 2, and there is also an air inlet 1211 near the nozzle piece 4, and the cold air continuously cools, so the temperature rise is low, minimizing the risk of flashback.

[0091] Fifthly, an outdoor cooking appliance with a small folded volume, a large unfolded support surface and a stable structure is provided. The unfolding and folding are simple and convenient, and it is suitable for use in various outdoor scenarios.

[0092] Sixthly, the structure of the cooking appliance is simple and the manufacturing cost is low, which is suitable for large-scale popularization and use.

[0093] Seventhly, the CO in the flue gas emission is low, and it is safe and environmentally friendly to use.

[0094] Eighthly, the wind resistance performance is further improved compared with traditional infrared burners. While achieving stronger wind resistance performance, it can maintain a good combustion state, ensuring that the heating performance in a strong outdoor wind environment is basically not deteriorated.

[0095] The present invention provides a direct-injection high-heat-intensity blue-light infrared gas appliance, comprising: a combustion member, the combustion member including a furnace body and an ejector tube that are interconnected, a premixing adjustment plate fixedly connected to the furnace body and adapted thereto is provided inside the furnace body, the premixing adjustment plate is disposed above the ejector tube, and a plurality of air inlets are provided on the ejector tube; a flame stabilizing member, the flame stabilizing member is disposed at one end of the furnace body away from the ejector tube, and the flame stabilizing member is disposed opposite to the premixing adjustment plate, and an ignition electrode is further provided on the flame stabilizing member; an ignition member, the ignition member is disposed inside the furnace body, and the ignition member further includes an ignition positive electrode, the ignition positive electrode is disposed through and exposed outside the flame stabilizing member, and the ignition positive electrode and the ignition electrode are disposed close to each other; a nozzle member, the nozzle member is connected to one end of the ejector tube away from the furnace body. Through the gas appliance provided by the present invention, high-pressure gas is vertically sprayed upward into the ejector tube through the nozzle member, and air is sucked in from a plurality of air inlets in the direction perpendicular to the gas flow direction by using the pressure difference and enters the furnace cavity. The premixing adjustment plate disposed in the center of the furnace cavity can extend the premixing path and adjust the distribution of the mixed gas, effectively shorten the axial length of the ejector tube and the radial dimension of the furnace cavity, efficiently form a uniform combustible mixed gas, and reach the surface of the flame stabilizing member at the head of the burner, and then the gas is ignited by the built-in ignition member. Most of the gas is distributed over most of the area in the middle region of the flame stabilizing member to form infrared combustion, and atmospheric combustion with blue flame microflames is formed at the outer edge portion, so as to achieve efficient combustion and high heat intensity of the burner, effectively reduce the volume of the gas appliance and make it more portable.
