Description of the drawings
Fig. 1 is the exploded view of one embodiment of the utility model.
Fig. 2 is the assembling stereogram of one embodiment of the utility model.
Fig. 3 is the sectional arrangement drawing of one embodiment of the utility model.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1-Fig. 3, this upper air inlet direct injection infrared stove head, including it is equipped with central burner 11 and outer annular burner
Lid is connected to external ring fire cover 22 and central flame cap 21 respectively on 12 stove seat 1, central burner 11 and outer annular burner 12, described outer
Being equipped in ring burner 12 makes it generate point conductance flowing plate 3 for uniformly dividing gas air-flow.Since 12 area of outer annular burner is larger, because
This combustion gas distributes in the region where outer annular burner 12 in uneven baseset, divides gas by being arranged in outer annular burner 12
Deflector 3 helps to improve the combustion gas gas separation effect of outer annular burner 12, makes the combustion gas of outer annular burner 12, external ring fire cover 22
Output is uniform, during sustained combustion, the combustion gas of burner is enable fully to burn, exhaust gas will not be exceeded, multiple without being arranged
Fire cover simplifies furnace head structure and reduces production cost, and the stove seat with central burner 11,12 structure of outer annular burner
1, inside be not susceptible to block, burning area, combustion power bigger disclosure satisfy that the requirement of level-one efficiency.
Further, described point of conductance flowing plate 3 radially distributes along outer annular burner 12 several airflow diversion holes 31,
Airflow diversion hole 31 helps to form the air-flow of uniformly output combustion gas in outer annular burner 12.
