For achieving the above object, the utility model is taked following technical scheme: a kind of New Gas Burner Unit, the burner, frame corresponding with annular air cavity and center air cavity respectively big fire lid and the little fire on fiery cage on the burner and fiery cage that are provided with annular air cavity and center air cavity in comprising cover, fire covers and all has fire hole, described burner side is provided with big fire nozzle and the little fire-fighting mouth of source of the gas being introduced annular air cavity and center air cavity, it is characterized in that described burner side is provided with the primary air adjusting device of control air inlet amount.Primary air adjusting device by the burner side is regulated the primary air air inflow that enters annular air cavity, and combustion gas is fully mixed, and improves efficiency of combustion.

Described primary air adjusting device is between burner and big fire nozzle described in the utility model, comprise and be located at the tube connector that the burner side is communicated with annular air cavity, rotating accent airduct is housed in it, the tube connector outboard end is fixed with outwardly directed link, the big fire nozzle is positioned at link one end, it forms the space between the two over against transferring the airduct air inlet.During use as required rotation in good time adjust airduct, change distance between itself and the nozzle, regulate air capacity, make combustion gas and primary air fully mix the back and feed in the burner annular air cavity, it is more abundant to burn; In addition, adjust airduct and can adopt screw pair to cooperate, rotate the perforate that forms with respect to existing sheet metal and advance air structure with tube connector, locate more reliable, the difficult displacement.

Be provided with an annular transition cover plate between fiery cage described in the utility model and the burner, circumferentially be distributed with the hollow circuit cylinder that protrudes in lid surface more than three on it, there is transitional pore to be communicated with annular air cavity and fiery cage in the cylinder, the cylinder end face is step-like ringwise, and fiery cage frame forms the gap with the transition lid surface on ring-shaped step.Rely on the hollow circuit cylinder of three projectioies on the transition cover plate to hold up fiery cage, make the bigger gap of formation between fiery cage and the transition cover plate, allow more air (being auxiliary air) add to around the little fire lid, with the combustion gas mixing after-combustion in the little fire lid, little fire burns is more abundant, has overcome the combustion gas waste that in the past brought because of little fire is less.

The primary air adjusting device that the utility model is installed by spiral positioning is regulated the primary air air inflow that enters annular air cavity, increase transition cover plate is laid fiery cage allows more air (being auxiliary air) add to around the little fire lid, combustion gas is fully mixed, the big and small fire dish fires and significantly strengthens, and efficiency of combustion is improved.

Below in conjunction with the description of drawings and the specific embodiment the utility model is described further.
