DETAILED DESCRIPTION

[0027] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0028] As a specific embodiment, the high heat dissipation stove burner of the embodiment of the utility model comprises an energy supply bracket 1 and a peripheral burner assembly 2; the energy supply bracket 1 is provided with a horizontal outer ring gas nozzle 12 and a horizontal inner ring gas nozzle 13.

[0029] The peripheral burner assembly 2 includes an air guide cover 21 and a fire cover 29. The air guide cover 21 is provided with an outer ring gas path 22 and an inner ring gas path 23. Usually, a through hole is opened on the fire cover 29 for the output and combustion of the mixed gas of the fuel gas and air described later.

[0030] The outer ring gas path 22 includes an outer ring gas inlet 221, an outer ring groove 228, and an outer ring gas outlet 229 that are connected in sequence; the inner ring gas path 23 includes an inner ring gas inlet 231, an inner ring groove 238, and an inner ring gas outlet 239 that are connected in sequence; the inner ring groove 238 is located in the outer ring groove 228; and the fire cover 29 surrounds the outer ring gas outlet 229 and the inner ring gas outlet 239 respectively. For example, when viewed from above, the inner ring groove 238 and the outer ring groove 228 are both annular and have the same center. Usually, a plurality of outer ring gas outlets 229 are provided on the inner ring groove 238.

[0031] The outer ring gas nozzle 12 and the inner ring gas nozzle 13 are respectively facing the outer ring air inlet 221 and the inner ring air inlet 231. Usually, a gap is provided between the outer ring gas nozzle 12 and the outer ring air inlet 221. When the gas is sprayed from the outer ring gas nozzle 12 into the outer ring air inlet 221, air will enter the outer ring air inlet 221 from the gap. The gas and air are mixed in the outer ring gas path 22 and then output from the outer ring air outlet 229 and burn on the fire cover 29. The same is true for the inner ring gas nozzle 13 and the inner ring air inlet 231, which will not be described in detail below.

[0032] The air guide cover 21 includes heat sinks 211 evenly arranged around the outer groove 228, and the heat sinks 211 are all located outside the outer groove 228. The heat sinks 211 can improve the heat dissipation effect of the air guide cover 21, thereby preventing the air guide cover 21 from being overheated and scalding the glass plate and other installed objects, and can also improve the service life of the air guide cover to a certain extent.

[0033] As one of the specific implementations, the heat sink 211 is arranged at the bottom of the air guide cover 21 and a gap is arranged between the heat sink 211 and the energy supply bracket 1. During installation, the heat sink 211 and the energy supply bracket 1 clamp the glass plate and other objects to be installed. The heat sink 211 improves the heat dissipation effect while reducing the heat transferred to the glass plate and other objects to be installed, which can further prevent the air guide cover 21 from being overheated and scalding the glass plate and other objects to be installed.

[0034] As one of the specific implementations, the outer ring groove 228 is annular in shape when viewed from above; the outer ring air inlet 221 is located below the outer ring groove 228, and the outer ring groove 228 is provided with an annular fan opening 222 so that the outer ring air inlet 221 is connected to the outer ring groove 228. It is easy to understand that the outer ring air inlet 221 is connected to the outer ring groove 228 through a pipeline (not shown in the drawings). It can provide over-gas to achieve heat insulation, thereby further preventing the air guide cover 21 from being overheated and scalding the glass plate and other installed objects.

[0035] As one of the specific implementations, the setting angle of the annular fan opening 222 is an angle away from the outer ring air inlet 221. It is easy to understand that the annular fan opening 222 can be rotated around the outer ring groove 228 to set different angles, so it can be rotated to the angle farthest from the outer ring air inlet 221 (judged by the center point of the annular fan opening 222 when viewed from above). It can further provide over-gas to achieve heat insulation, thereby further preventing the air guide cover 21 from being too hot and scalding the glass plate and other installed objects.

[0036] As one of the specific implementations, an air baffle 223 is provided on the inner wall of the annular fan opening 222, and the bottom end surface of the air baffle 223 is higher than the bottom end surface of the outer ring groove 228. The gas flowing upward from the annular fan opening 222 is guided to the portion of the outer ring groove 228 close to the outer ring gas inlet 221, so that the gas distribution in the outer ring groove 228 is relatively uniform, thereby ensuring that each fire cover 29 burns relatively uniformly.

[0037] As one of the specific embodiments, it also includes an inner burner assembly 3, and the fire cover 29 corresponding to the inner circle air outlet 239 in the fire cover 29 is an inner circle fire cover 291; the inner burner assembly 3 includes an inner air supply pipe 31 and an inner air bleed pipe 32 provided with a side hole 321, the top of the inner air supply pipe 31 is directly opposite to the bottom of the inner air bleed pipe 32, the inner circle fire cover 291 is provided with an inner hole (i.e., the inner combustion hole 292), and the inner air bleed pipe 32 is arranged in the inner hole of the inner circle fire cover 291. The fuel gas output from the inner air bleed pipe 32 can further increase the combustion area of ​​the inner circle fire cover 291, thereby improving the heating efficiency. The top of the inner hole of the inner circle fire cover 291 is truncated cone-shaped to further increase the combustion area.

[0038] As one of the specific implementations, the air guide cover 21 includes a lower fire cover 283 , an upper shell 282 , and a lower shell 281 stacked in sequence from top to bottom, and the heat sink 211 is arranged on the outer periphery of the bottom end of the upper shell 282 .

[0039] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0040] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0041] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0042] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the relevant standards of dimensional tolerance.
