Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.At this it should be noted that
The explanation of these embodiments is adapted to assist in and understands this utility model, but be not intended that restriction of the present utility model.This
Outward, as long as technical characteristic involved in each embodiment of this utility model disclosed below does not constitutes punching each other
Dash forward and just can be combined with each other.
As shown in Figures 1 to 9, it is a kind of burner, including:
Gas inlet chamber, center 3；Described central flame gas inlet chamber 3 is provided with center combustion gas lid 1, center gas inlet
Chamber 3 communicates with extraneous combustion gas, is provided with ring fire steady flame groove 32 in several on the wall in gas inlet chamber, center 3；
The combustion gas annular groove 4 of outer ring fire；Described combustion gas annular tongue 4 is provided with outer ring fire combustion gas lid 2, combustion gas annular
The outer wall of groove 4 is provided with several outer ring fires steady flame groove 42, is provided with biography fire passage 43, described biography on combustion gas annular groove 4
The air inlet of fire passage 43 is positioned at the outside of combustion gas annular groove 4, and it is recessed that the gas outlet of biography fire passage 43 is positioned at combustion gas annular
The inner side of groove 4, is provided with side igniting groove 431 on the wall passing fire passage 43, is respectively equipped with two on the inwall of combustion gas annular groove 4
Individual ignition slot 44, two ignition slot 44 lay respectively at biography fire passage 43 side, and it is recessed that gas inlet chamber, described center 3 is positioned at combustion gas annular
The center of groove 4；And
