Abstract

The utility model relates to a gas burner, which comprises a burner body, a flame separator cover, a base bottom, an inner ring fire cover and an outer ring fire cover, wherein, inner ring fire is provided with a single gas inlet channel, and outer ring fire is also provided with a single gas inlet channel. Thus, an independent gas inlet mode is used, and the size of the fire power of a center flame head and an outer flame head can be solely regulated. The structure is simple, and the used is convenient.

Description

A kind of gas burner

The utility model relates to a kind of gas burner.

At present, gas-cooker on the market generally uses a kind of gas burner of many flame fronts, discloses a kind of gas burner as Chinese patent 98120026.5, although the gas burner of these many flame fronts is simple in structure, flame is even.But all there is a common defective, because many flame fronts adopt same Intaker controller, the adjusting of flame size is controlled by same control device, control device is transferred air inlet when big, the firepower of all flame fronts all strengthens, when control device was turned air inlet down, the firepower of all flame fronts all reduced.Like this, make troubles for people in the use, marquis when many, user wish and can regulate separately the firepower size of flame of centre head or external flame head respectively.

The purpose of this utility model is to provide the gas burner of a kind of energy independent regulation flame of centre head and external flame head.

The purpose of this utility model is achieved in that

A kind of gas burner comprises burner body, the flame trap lid, and at the bottom of the pedestal, interior ring fire lid, external ring fire cover is characterized in that being provided with uptake ventilator on burner body, and the upper end of uptake ventilator communicates with interior ring fire combustion gas chamber; Also be provided with a plurality of vertical outer shroud air flues on burner body, isolated between outer shroud air flue and the uptake ventilator, the outer shroud air flue communicates with the outer shroud annular air cavity; Ring fuel gas supply passage at the bottom of the pedestal, being provided with, the inlet end of blast tube is connected with the control valve of control air inflow, and the front end of blast tube is equipped with nozzle, and nozzle and uptake ventilator are on same axis; On at the bottom of the pedestal, be provided with outer shroud fuel gas supply passage, the inlet end of blast tube also is connected with the control valve that can control air inflow, the front end of blast tube forms a plurality of outlet passageways, and a plurality of outer shroud fire-fighting mouths are housed, the quantity of outer shroud fire-fighting mouth is identical with the quantity of outer shroud air flue, and be installed in the outer shroud air flue on same axis.

Aforesaid a kind of gas burner, ring fire combustion gas chamber is made of the upper surface in the centre of the lower surface of flame trap lid and burner body in it is characterized in that.

Aforesaid a kind of gas burner, the quantity that it is characterized in that the outer shroud air flue can be 3 to 6.

The utility model adopts independently intake method, can regulate the firepower size of flame of centre head and external flame head separately.It is simple in structure, and is easy to use.

Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation:

The utility model comprises burner body 1, flame trap lid 2, at the bottom of the pedestal 3, interior ring fire lid 4, external ring fire cover 18, wherein be provided with uptake ventilator 5 on burner body 1, the upper end of uptake ventilator 5 communicates with interior ring fire combustion gas chamber 6, and interior ring fire combustion gas chamber 6 is made of the upper surface 8 in the centre of the lower surface 7 of flame trap lid 2 and burner body 1.Flame trap lid 2 is provided with circumferential fire hole 9 and communicates with interior ring fire combustion gas chamber 6, ring fire in combustion gas just constitutes when flowing out burning by these fire holes 9.

Also be provided with a plurality of vertical outer shroud air flues 10 on burner body 1, isolated between outer shroud air flue 10 and the uptake ventilator 5, its quantity can be 3 to 6, and why a plurality of passages are set, and is in order to guarantee that burning evenly.The horizontal air flue 11 of the upper end connection of outer shroud air flue 10 communicates with outer shroud annular air cavity 12 again, on flame trap lid 2, equally also be provided with circumferential fire hole 13, fire hole 13 communicates with outer shroud annular air cavity 12, and combustion gas just constitutes outer ring fire when flowing out burning by these fire holes 13.

Ring fuel gas supply passage 14 in being provided with on 3 at the bottom of the pedestal, the inlet end of blast tube 14 are connected with the control valve that can control air inflow, and the front end of blast tube 14 is equipped with nozzle 15, and nozzle 15 and uptake ventilator 5 are on same axis.

Be provided with outer shroud fuel gas supply passage 16 on 3 at the bottom of the pedestal, the inlet end of blast tube 16 is connected with the control valve that can control air inflow, the front end of blast tube 16 forms a plurality of outlet passageways, and a plurality of outer shroud fire-fighting mouths 17 are housed, the quantity of outer shroud fire-fighting mouth 17 is identical with the quantity of outer shroud air flue 10, and be installed in outer shroud air flue 10 on same axis.

The utility model in use, combustion gas is supplied with simultaneously by interior ring fuel gas supply passage 14 and outer shroud fuel gas supply passage 16, the combustion gas of ring blast tube 14 sprays into uptake ventilator 5 by nozzle 15 in entering, ring fire combustion gas chamber 6 in uptake ventilator 5 enters again, be assigned to fire hole 9 on the flame trap lid 2, ring fire in these fire holes 9 just constitute by interior ring fire combustion gas chamber 6 when burning.If the size of ring fire in regulating, the control valve of regulating the inlet end that is connected blast tube 14 gets final product.The combustion gas that enters outer shroud fuel gas supply passage 16 sprays into outer shroud air flue 10 by a plurality of outer shroud fire-fighting mouths 17, enter outer shroud annular air cavity 12 through horizontal air flue 11 again, be assigned to flame trap by outer shroud annular air cavity 12 and cover 2 fire hole 13, ring fire outside these fire holes 13 just constitute when burning.If regulate the size of outer ring fire, the control valve of regulating the inlet end that is connected blast tube 16 gets final product.
