The technical solution of the utility model is: the utility model includes regulating block, silk screen, induction tunnel, the connector with regulatory function, silk screen is rolled into cylindric, the head inwall that is close to induction tunnel is also fixed thereon, and regulating block is placed in the head of induction tunnel, and is packed on the induction tunnel.
Above-mentioned silk screen is fixed by welding in the head inwall of induction tunnel.
Above-mentioned regulating block is provided with locating hole, and connector passes the set locating hole of regulating block, and twists solid on induction tunnel.
Above-mentioned connector is a screw.
Have some regulating tanks on the above-mentioned regulating block, the head of induction tunnel has and somely matches with regulating tank, to regulate the air inlet of primary air air inflow.
The air inlet rear of above-mentioned induction tunnel is provided with mixed air cavity, and mixed air cavity is flat;
Above-mentioned induction tunnel is provided with some fire holes in two proceeds posterolateral of mixing air cavity, and the fire hole front end is provided with tube wall angled, and the stator blade of recessed induction tunnel pipe shaft.
Above-mentioned induction tunnel is provided with some steam vents in fire hole two proceeds posterolateral.
Above-mentioned induction tunnel end flattens into the sealing of sealing, and sealing offers installing hole.
One side of above-mentioned induction tunnel postmedian has some secondary steam vents.
The utility model owing to adopt comprises to be regulated and the two-part structure of injection, and primary air is pre-mixed for twice in induction tunnel, carries out completing combustion then under the help of auxiliary air.The utility model can use the different source of the gas of multifrequency nature; Still can smooth combustion when bleed pressure changes, safe in utilization; Can adapt to various barbecue environment, need not special blast apparatus; The utility model burner design is ingenious, and is simple in structure, and processing cost is low; And can make gas completing combustion, ignition temperature has improved efficiency of combustion greatly far above the diffusion flame burner height, and comparable general gas baking oven is saved and surpassed 10% fuel.The utility model is that a kind of design is ingenious, function admirable, the convenient and practical burner that is used for fuel gas oven.
