1 top is equipped with center gas separating seat 3, and center gas separating seat 3 is equipped with the channel center Fen Qi 31, and the side of ontology 1 is equipped with center mistake
Gas channel 13,13 one end of the channel the center Guo Qi are connected to the center channel Fen Qi 31, and other end is equipped with central nozzle 22.Institute
State outer ring nozzle 21 and the lower part of ontology 1 be mounted on by outer ring nozzle holder 23, the outer ring nozzle holder 23 under ontology 1
Portion forms the air air intake (not marking in figure) being connected to outer ring premix chamber 11, between the ontology 1 and center gas separating seat 3
Equipped with central air passage 30,30 one end of central air passage is connected to the external world of ontology 1, other end and the channel center Fen Qi
31 connections, central air passage 30 can design needs according to environment-protection oven, be fabricated to and allow air to enter in the aperture of environment-protection oven top,
It can enter in environment-protection oven lower part aperture air, air can also be allowed to enter in the aperture simultaneously of environment-protection oven top and the bottom, realize three-dimensional oxygen supply
It is combustion-supporting.
When in use, the step of outer ring spray combustion gas, is (as shown in solid arrow in figure) burner of the utility model:
At center, gas separating seat 3 covers central flame cap 41, divides air cavity 12 to cover external ring fire cover 42 in outer ring, and outer ring nozzle 21 is arranged in main body
1 bottom, when the outer ring spray combustion gas of burner, combustion gas sprays into outer ring premix chamber 11 from the outer ring nozzle 21 of 1 bottom of main body, at this point, outside
11 surrounding of ring premix chamber generates negative pressure, and air enters outer ring premix chamber 11 and combustion gas mixing from air air intake, to guarantee combustion gas
Full combustion, improve combustion efficiency, be sprayed onto outer ring after mixing and divide evenly dispersed ejection in air cavity 12, entered back into after ejection
External ring fire cover 42 is used for burning, and burning is more evenly, sufficiently；The step of its center spray combustion gas is (arrow institute as dashed lines
Show): the setting of central nozzle 22 is in 1 side of main body, when burner centre sprays combustion gas, central nozzle 22 of the combustion gas from 1 side of main body
Into, then successively sprayed by the channel center Guo Qi 13, the center channel Fen Qi 31, during ejection, central air passage 30
Generate negative pressure, make the center channel Fen Qi 31 suck the appropriate external world air and on be sprayed onto central flame cap 41, fired during ejection
Gas and air mix naturally, play the role of drawing oxygen and aiding combustion, and central flame cap 41 is entered back into after ejection and is used for burning, the gas supply side
Formula keeps the path of center spray combustion gas shorter, helps the outlet pressure for increasing central flame cap 41, is also convenient for the supplement of peripheral air, has
Help its completely burned.
Double direct injection structures of the burner of the utility model using outer ring spray combustion gas, center spray combustion gas, burner operation
When, fuel gas injection dynamics is larger, and firepower is more violent, and combustion flame and calory burning is promoted to float up in cookware, improves combustion
Burner realizes energy saving purpose to the heating efficiency of cookware.
Since center gas separating seat 3 is located at 1 top of main body, outer ring premix chamber 11 will not be occupied and outer ring divides the volume of air cavity 12
With space, their practical ventable areas of section are not influenced, and the effect of combustion gas and outer ring spray combustion gas is sprayed compared with the prior art in center
It is all good, and help to make the overall structure of burner more compact.
Further, the bottom of the center gas separating seat 3 is equipped with and from top to bottom extends downwardly into outer ring and divide inside air cavity 12
Divide gas coning 32, divide gas coning 32 in column taper, the outer diameter of gas coning 32 is divided from top to bottom to gradually become smaller, divides gas coning 32 by setting, outside
When ring spray combustion gas, the gas sprayed is evenly dispersed around under the action of dividing gas coning 32, the dispersion effect of gas is more preferable,
Mix with air also more sufficiently, promote combustion gas completely burned, avoid the generation of harmful exhaust, flue gas, thus reach environmental protection mesh
's.The fuel gas return-flow for dividing gas coning 32 that can also prevent external ring fire cover 42, avoids tempering phenomenon, can also block foreign matter in ontology 1 and fall into
And block outer ring nozzle 21.
Further, it is described divide gas coning 32 protrude into outer ring divide air cavity 12 depth be greater than outer ring divide the one of 12 depth of air cavity
Half, the center channel Fen Qi 31 divides air cavity 12 for coaxial arrangement with gas coning 32, outer ring is divided, which is further ensured that, sprays
Gas by divide the active force of gas coning 32 be it is identical, guarantee enter external ring fire cover 42 gas it is uniform.
Further, annular ledge 33 is equipped with outside the center gas separating seat 3, the two passes through several radial buttress
34 connections, the center channel Fen Qi 31 are formed in annular ledge 33, wherein a buttress 34 and annular ledge 33, center gas separating seat
3, the outer surface of buttress 34 and annular ledge 33 is collectively formed several outer rings for dividing air cavity 12 to be connected to outer ring and crosses gas channel 14,
The jet that outer ring divides air cavity 12 to external ring fire cover 42 is not influenced.The annular ledge 33 is mounted on this by screw thread or insert structure
The top of body 1 is fixedly mounted on the body 1 convenient for center gas separating seat 3, and the preferred annular ledge 33 of the present embodiment is formed by die casting
