[0039] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0040] Please refer to Figures 1-6 This invention provides a burner, including a burner head 1, a first heat insulation component 3, and an infrared combustion plate 5. The burner head 1 includes a burner head body 11 and a surrounding plate 12 disposed on the upper outer side of the burner head body 11. The burner head body 11 has an inner mixing chamber 102 and an outer mixing chamber 101 sequentially formed from the inside to the outside. The first heat insulation component 3 is installed in the outer mixing chamber 101 and located inside the surrounding plate 12, forming a first heat insulation cavity between the first heat insulation component 3 and the surrounding plate 12. A first heat insulation material 4 is disposed within the first heat insulation cavity. The infrared combustion plate 5 is installed at the upper end of the burner head body 11 and located above the inner mixing chamber 102 and the outer mixing chamber 101. By forming a first heat insulation cavity between the first heat insulation component 3 and the surrounding plate 12, and placing the first heat insulation material 4 within the first heat insulation cavity, heat insulation is achieved around the burner head 1.

[0041] Optionally, the first heat insulation component 3 includes a first base plate 31 and a side wall plate 32 connected to each other. The first base plate 31 has multiple guide holes 311 extending radially along its surface. These guide holes 311 are distributed circumferentially along the first base plate 31. The first base plate 31 also has multiple guide plates 312 extending radially along its surface. Each guide plate 312 corresponds to one of the guide holes 311. The guide plates 312 are positioned on the first side of the guide holes 311 and extend from bottom to top. The first bottom plate 31 is inclined to the second side of the guide hole 311. Both the first and second sides of the guide hole 311 extend radially along the first bottom plate 31. The first bottom plate 31 is arranged horizontally in the middle of the outer mixing chamber 101 to divide the outer mixing chamber 101 into an upper mixing chamber 1011 and a lower mixing chamber 1012 located below the upper mixing chamber 1011. The side wall plate 32 is arranged vertically on the inner side of the surrounding plate 12 and forms a first heat insulation cavity with the surrounding plate 12.

[0042] Optionally, the system also includes an ejector assembly 2, which comprises an outer ejector 21 and an inner ejector 22. The outer ejector 21 is connected to the lower mixing chamber 1012, and the inner ejector 22 is connected to the inner mixing chamber 102. Specifically, the fuel gas and air undergo a first mixing in the outer ejector 21. The fuel gas and air are then injected into the lower mixing chamber 1012 through the outer ejector 21 for a second mixing. The mixture then flows upward through the guide hole 311 into the upper mixing chamber 1011. During this process, the fuel gas and air mixture forms an airflow along the circumference of the bottom plate under the guidance of the guide plate 312, thereby achieving a third mixing of the air and fuel gas. This improves the premixing effect of the air and fuel gas, enhances the mixing uniformity, and ultimately improves the combustion efficiency. Furthermore, the first bottom plate 31, located in the middle of the outer mixing chamber 101, also prevents the heat from the infrared burner from being transferred downwards, thus providing insulation.

[0043] Optionally, the enclosure 12 includes a second bottom plate 121 and a second side plate 122 connected to each other. The second bottom plate 121 is arranged in a horizontal direction, and the second side plate 122 is arranged in a vertical direction. The side wall 32 includes a third side plate 321 and a first top plate 322 connected to each other. The third side plate 321 is arranged in a vertical direction and is located inside the second side plate 122. The first top plate 322 is arranged in a horizontal direction and is located above the second bottom plate 121. The second bottom plate 121, the second side plate 122, the third side plate 321 and the first top plate 322 enclose a first heat insulation cavity. The structure is simple and compact, and it is easy to install the first heat insulation material 4.

[0044] Optionally, the device also includes a liquid collection tray 6, which has an upward-facing liquid collection trough 601. The liquid collection tray 6 is fitted around the periphery of the surrounding plate 12 and has a first ventilation gap 602 between it and the surrounding plate 12. The periphery of the infrared combustion plate 5 is located above the liquid collection trough 601. The liquid collection tray 6 serves two purposes: firstly, it can collect liquid overflowing from the pot during cooking; secondly, since it is located on the outer periphery of the surrounding plate 12, it can also provide insulation for the outer periphery of the surrounding plate 12, thereby further improving the heat insulation effect on the burner. In addition, by providing a first ventilation gap 602 between the periphery of the surrounding plate 12 and the liquid collection tray 6, secondary air can flow through the first ventilation gap 602 to the outside of the infrared combustion plate 5, thereby improving the combustion efficiency of the infrared combustion plate 5. When the secondary air flows through the first ventilation gap 602, it can also carry away some of the heat from the surrounding plate 12, causing this heat to flow upward and contact the bottom of the pot, thereby improving the thermal efficiency of the burner.

[0045] Optionally, a bottom heat insulation component 7 is also included, which is disposed on the outer side of the lower part of the burner body 11. This heat insulation component 7 insulates the lower part of the burner body 11, reducing the amount of heat entering the gas stove housing through the lower side of the burner body 11, thereby protecting the electronic components housed in the housing.

[0046] Optionally, the bottom insulation assembly 7 includes a second insulation element 72, a third insulation element 71, and a second insulation material 73. The second insulation element 72 covers the outer side of the lower part of the burner head body 11. The third insulation element 71 surrounds the outer periphery of the first insulation element 3 and has a second gap with the second insulation element 72. The second insulation material 73 is disposed in the second gap.

[0047] Optionally, the second heat insulation component 72 includes a third base plate 721 and a fourth side plate 722 connected to each other. The third base plate 721 is located below the burner body 11, and the fourth side plate 722 is located on the lower periphery of the burner body 11 to cover the lower part of the burner body 11 and achieve a heat insulation effect.

[0048] Optionally, the third heat insulation member 71 includes a first side plate 711 and a second top plate 712 connected to each other. The first side plate 711 surrounds the outer periphery of the fourth side plate 722. The second top plate 712 is located below the liquid tray 6 and has a second ventilation gap communicating with the first ventilation gap 602 between it and the liquid tray 6. Secondary air flows through the second ventilation gap to the first ventilation gap 602, thereby carrying away the heat outside the surrounding plate 12 and providing secondary air for the infrared combustion plate 5.

[0049] Optionally, the second heat insulation material 73 is disposed on the side of the second gap near the second heat insulation member 72, and a second heat insulation cavity is provided between the second heat insulation material 73 and the second heat insulation member 72. By providing the second heat insulation cavity, the heat transfer effect is reduced when heat is transferred in the second heat insulation cavity, and there is no need to provide an excessively thick second heat insulation material 73, which can still achieve a good heat insulation effect. On the one hand, the amount of second heat insulation material 73 is reduced, and on the other hand, the product weight is reduced.

[0050] Optionally, both the first insulation material 4 and the second insulation material 73 are insulation cotton.

[0051] Optionally, a first clearance hole 702 is provided on the fourth side plate 722, a second clearance hole 701 is provided on the first side plate 711, and a third clearance hole 703 is provided on the second heat insulation material 73. The first clearance hole 702, the second clearance hole 701 and the third clearance hole 703 are connected to form a clearance channel 700. The outer ejector tube 21 and the inner ejector tube 22 are both connected to the burner body 11 by passing through the clearance channel 700, so that the outer ejector tube 21 is connected to the outer mixing chamber 101 and the inner ejector tube 22 is connected to the inner mixing chamber 102.

[0052] Optionally, the burner body 11 is also provided with a secondary air channel 103 located inside the internal mixing chamber 102. The secondary air enters the infrared combustion plate 5 through the secondary air channel 103 to increase the secondary air in the middle of the infrared combustion plate 5, thereby improving the combustion efficiency.

[0053] Optionally, it also includes an ignition needle 8, which is disposed in the secondary air channel 103 and extends to the upper side of the infrared combustion plate 5 to achieve ignition.

[0054] Another aspect of this utility model provides a gas stove, including the burner described above.

[0055] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
