The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, and the injection mixing tube separates with burner, meets embedded gas-cooker instructions for use, and combustion flame is even, and thermic load can greatly can be little, the novel household burner for gas stove that the thermal efficiency is high.

The technical solution of the utility model is, a kind of novel household burner for gas stove, by nozzle, the air-conditioning plate, 8 word air doors, the injection mixing tube, elbow, combustion chamber, furnace shell, the fire lid, the ornamenting circle, the installation location-plate of spray point and thermocouple probe, spray point and thermocouple probe are formed, its characteristics are: fire covers the inclined-plane of the inclined-plane of fire hole and furnace shell to the center, the alignment pin that fire covers links to each other with location, combustion chamber hole, furnace shell is riveted mutually with combustion chamber, the combustion chamber small end be with furnace shell in the circle of round heart deviation certain distance, keeping off the burner air inlet, the big end of combustion chamber has three positioning cylinders and an inlet tube outward, inlet tube inserts in the endoporus of elbow, the other end of elbow is inserted with the injection mixing tube, and the injection mixing tube links to each other with combustion chamber by screw.

Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, pressure basically identical during the root of gas arrival fire hole, the burned flame height is consistent.Because drag losses is very little in whole gas flow process, so the effect of injection mixing tube injection air is fine, makes primary air fully burn.Because the bottom surface at combustion chamber has three contour cylinders, make burner and kitchen range face form the gap, again because combustion chamber has endoporus, make air can enter the endoporus of combustion chamber from the bottom surface of kitchen range face and burner, thereby arrive by the interior fire hole of fire lid, enough required auxiliary airs of burning are provided, guarantee fully burning.Because the combustion chamber air inlet pipe is inserted in the gas outlet of elbow and close-fitting, burner is by three fixed high cylinders of combustion chamber bottom surface and kitchen range face location again, and the installation of burner is reliable and stable, makes pot to overflow soup and flow on the kitchen range face tool promotional value.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a sectional structure schematic diagram of the present utility model.

Fig. 2 takes plan structure schematic diagram behind fire lid, the case ring away for the utility model.

Among the figure, ornamenting circle 9 covers on fire lid 8, the fire tank that inside and outside fire hole is communicated is arranged on the fire lid 8, the inclined-plane of fire lid 8 dependence fire holes and the inclined-plane of furnace shell 6 are to the center, alignment pin on the fire lid 8 links to each other with the location, hole of combustion chamber 5, furnace shell 6 is riveted mutually with combustion chamber 5, combustion chamber 5 small ends be with furnace shell 6 in the circle of round heart deviation certain distances, keeping off the burner air inlet, outside the combustion chamber 5 big ends three positioning cylinders and an inlet tube are arranged, inlet tube inserts in the endoporus of elbow 7, and the other end of elbow 7 is inserted with injection mixing tube 4, and injection mixing tube 4 links to each other with combustion chamber 5 by screw.Locating slot on the 8 word air doors 3 is corresponding with the alignment pin at injection mixing tube 4 air inlet places, makes the 3 location interference of 8 word air doors be installed in the air inlet place of injection mixing tube 4, and uses rivet.In the screw that nozzle 1 screws on the 8 word air doors 3, be with air-conditioning plate 2 on the nozzle 1.Wherein, combustion chamber 5 off-centre operations and furnace shell fire hole inclined-plane interior round-formed by little gradually to the slit of big symmetry, the width in its slit is the 0.5-1.5 millimeter, the best is 1 millimeter, minimum slit is the 0.5-2 millimeter, the slit gross area is fire hole area 1.5-1.99 times, and best slit is 1 millimeter, and the best gross area is 1.8 times of fire hole area.The inclined-plane of the upper/lower terminal of combustion chamber 5 and furnace shell 6 constitutes cavity of resorption, the interior empty formation epicoele of fire lid 8, and upper and lower two chambeies have the slit to go here and there mutually.Make the mist with certain dynamic pressure that enters into burner from injection mixing tube 4 through after mixing, the gas dynamic pressure power, the static pressure that enter behind the burner from the slit reach unanimity.Though this does not meet the numerical value that two books are recommended, pressure basically identical during the root of gas arrival fire hole, the burned flame height is consistent.Because drag losses is very little in whole gas flow process, so the effect of injection mixing tube injection air is fine, makes primary air fully burn.Wherein, spray point 11, thermocouple probe string are crossed the endoporus of combustion chamber 5, between combustion chamber 5 and kitchen range face the gap of deciding cylinder are arranged.The installation location-plate 10 of spray point 11, thermocouple probe serves as the location benchmark with the cylindrical of elbow 7 ventholes, is fixed point with elbow 7 air inlet positions and injection mixing tube screw, by fixedly the lower end and the spring of injection mixing tube screw are located.The air inlet diameter of burner be injection mixing tube 4 outlet diameter 1-1.5 doubly, the best is 1.5 times.Therefore the loss of dynamic pressure be minimum, thereby mist arrival burner has and is beneficial to gas than higher dynamic pressure and fully mixes, and overcomes the resistance in slit.
