Description

Liquid fuel range

The utility model belongs to Domestic stove, is specially a kind of liquid fuel range.

That sells in the market has a kind of " gasification burner " (QHL35-8-3 type " kerosene gasification burner " that carburetion stove that the fire-resistant kitchen tools stove and accessory in Harbin City factory produces and Jinzhou City, Liaoning Province vapour stove factory produce) that uses liquid fuels such as kerosene, diesel oil, this " gasification burner " disciform fuel tank and be equipped with above fuel tank that a stone or metal plate for standing a stove on as a precaution against fire of fixedlying connected with fuel tank with pole etc. forms, there is a heating tube that links to each other with the stone or metal plate for standing a stove on as a precaution against fire bottom stone or metal plate for standing a stove on as a precaution against fire top near the stone or metal plate for standing a stove on as a precaution against fire place, connects a woven hose that stretches to the fuel tank inner bottom part again on the valve that the heating tube front end connects; Should " gasification burner " in use must at first gas injection in fuel tank, rely on the pressure that produces in the fuel tank that liquid fuel is pressed into woven hose, again through the flow through bottom of stone or metal plate for standing a stove on as a precaution against fire of heating tube, light the liquid fuel in the dish this moment, the flame liquid fuel heat in the heating tube of will flowing through, liquid fuel just is vaporizated into gas; This kind " gasification burner " though simple in structure, gas injection in advance when using, and make and keep certain pressure in the fuel tank, fuel combustion is insufficient, carbon distribution is too much in nozzle and the heating tube, needs often dismounting cleaning.Publication number CN2193499Y (ZL942285344) discloses a kind of " the dual-purpose stove and accessory of gas-liquid fuels ", when this stove and accessory uses liquid fuel, do not need in fuel tank gas injection to boost, can produce pressure automatically in the case, and can be in whole use, all the time can keep certain pressure in the fuel tank, fuel combustion is abundant, thermal efficiency height; But the evaporation burner of this stove and accessory is the annulus tube that an interior cover that is built-in with in the tube chamber is divided into the tube chamber exocoel and inner chamber; Facts have proved, as the evaporation burner of the critical piece of stove and accessory, owing to be an annulus tube of exocoel in having, manufacturing process is complicated, therefore and the burner that makes does not sometimes reach requirement, to the production in enormous quantities of this stove and accessory and promote the use of, just is subjected to certain influence and restriction.

The purpose of this utility model provides a kind of liquid fuel range, and this stove and accessory in use must gas injection in fuel tank, and fuel combustion is abundant, thermal efficiency height, the manufacturing process simple possible of evaporation burner is easy to processing and manufacturing simultaneously, is convenient to produce in enormous quantities and apply.

To achieve these goals, liquid fuel range of the present utility model is that the evaporation burner to above-mentioned second kind of stove and accessory (the dual-purpose stove and accessory of gas-liquid fuels) improves, promptly the interior cover that the tube chamber of evaporation burner is built-in with is divided into the tube chamber in an annulus tube of exocoel and inner chamber, change the independent interior annulus tube and the outer toroid tube that have inner chamber respectively into, interior annulus tube is a fuel vaporization chamber, the outer toroid tube is a fuel chamber, one side lower end of outer toroid tube connects front end and is connected with burnt gas valve with Gas Pipe, the combustion gas that the rear end connects heating plate divides fluid, the bottom of interior annulus tube is connected with the woven hose that is connected with fuel tank, and the upper end is connected with the Gas Pipe that is connected with burnt gas valve.Liquid fuel is heated in interior annulus tube, combustion gas after the vaporization divides fluid by Gas Pipe, burnt gas valve, combustion gas, major part enters the outer toroid tube, overflow by the fuel gas hole that outer toroid tube upper surface is equipped with, the small part combustion gas enters heating plate, overflow by the fuel gas hole on the heating plate, become vaporization flame after lighting.This evaporation burner after the improvement, inside and outside annulus tube separates separately, not only is easy to processing and manufacturing, and has strengthened the volume of fuel vaporization chamber, the liquid fuel that the heating plate that increases makes it in the vaporizer constantly is heated vaporization, has therefore increased the evaporating capacity and the vaporization intensity of this stove and accessory.
