The embodiment 1 of the utility model provides an internal rotary fire anti-dry burning burner, as shown in fig. 1, which comprises a burner head 1, an internal fire cover 2, an external fire cover 3, a temperature detection component 4 and a heat insulation component 5; the inner fire cover 2 and the outer fire cover 3 are both arranged on the furnace end 1, the temperature detection assembly 4 penetrates through the furnace end 1 and the inner fire cover 2 and is used for collecting the temperature of a pot on a burner to prevent the burner from being burnt, and the heat insulation assembly 4 is arranged between the inner fire cover 2 and the temperature detection assembly 4 and is used for preventing the flame of the burner from influencing the measurement precision of the temperature detection assembly 4;
specifically, the inner fire cover 2 and the outer fire cover 3 are both provided with inner fire swirling holes 21, and the inner fire swirling holes 21 enable the burner to form flames which rotate inwards from the edge of a combustion area when the burner burns;
like this, adopt above-mentioned structure, at the in-process of combustor work, prevent that the combustor from burning futilely through temperature detect subassembly 4, guarantee temperature detect subassembly's detection precision through thermal-insulated subassembly 5's setting, avoid it to receive flame radiation and become invalid.
As shown in fig. 2-3, the insulation assembly 5 includes an insulating sleeve 51;
specifically, the heat insulating sleeve 51 is annular, and is disposed around the temperature detection assembly 4;
in order to effectively block the influence of flame on the temperature detection assembly 4, the top of the heat insulation sleeve 51 is higher than the plane of the inner fire cover 2 and the outer fire cover 3.
A gap is left between the heat insulating sleeve 51 and the temperature detection assembly 4, and the gap forms a first cooling channel 52;
thus, during combustion in the burner, air is convected through the first cooling passage 52, and cooling of the temperature sensing assembly 4 is achieved.
