Wherein: described first combustion gas venthole place circle is concentric circles with second combustion gas venthole place circle; One end of described air inlet pipe is communicated with burner, and the other end is provided with the lid that keeps out the wind; Air inlet pipe is a hollow tubular, its with keep out the wind the internal diameter that covers link greater than with the internal diameter of burner link, be the undergauge structural transition between two internal diameters; The axis projection that covers that keeps out the wind is circle, and circular edge is to the extension that extends with air inlet pipe closure, formation is connected in air inlet pipe; Central authorities at the lid that keeps out the wind have the first combustion gas air admission hole, and the both sides up and down of this first combustion gas air admission hole have the first air inlet hole; Have and the corresponding second combustion gas air admission hole of the first combustion gas air admission hole and the first air inlet hole and the second air inlet hole on described air inlet pipe and the end face that is connected of lid that keeps out the wind; Air inlet pipe is arranged with sheath outward, and this sheath is that the end of hollow circuit cylinder, close stove is a frustum; Described kitchen range dish is an annular, which is provided with support.

Advantage of the present utility model and good effect are:

1. burner of the present utility model is provided with inside and outside two circle combustion gas ventholes, has increased the output of combustion gas, makes low-calorie combustion gas reach required calorific value when exporting.

2. the inside and outside combustion gas venthole on the utility model burner is provided with one heart, makes cooker be heated evenly.

3. the undergauge structure in the air inlet pipe of the present utility model can increase gas pressure.

4. air inlet pipe is arranged with sheath outward, has guaranteed the safety circulation of combustion gas.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1～4, the utility model comprises stove 1, kitchen range dish 2, burner 3, support 4, keep out the wind and cover 5 and air inlet pipe 6, its medium mess dish 2 is annulus, is located on the stove 1, in stove 1, be provided with burner 3, this burner 3 be positioned at kitchen range dish 2 interstitial holes under, one end of air inlet pipe 6 is connected with burner 3, and the other end is provided with to keep out the wind and covers 5; (aperture of the present embodiment first combustion gas venthole is 4.5～5.5mm), in the outside of the described first combustion gas venthole 12, (aperture of the present embodiment second combustion gas venthole is 3～4mm) to be evenly equipped with a plurality of second combustion gas ventholes 13 near the outer marginal circumference of burner 3 to be evenly distributed in a plurality of first combustion gas ventholes 12 on the described burner 3; On kitchen range dish 2, be provided with support 4, be used to support cookers such as the pot that is sitting on the kitchen range dish 2, spoon, kettle.The described first combustion gas venthole 12 places circle is concentric circles with the second combustion gas venthole, 13 places circle.

Air inlet pipe 6 is a hollow tubular, its with keep out the wind the internal diameter that cover 5 links greater than with the internal diameter of burner 3 links, be undergauge structural transition (promptly the part between two internal diameters is a frustum) between two internal diameters.Keep out the wind and cover 5 axis projection for circular, circular edge is to extend, form the extension that is connected in air inlet pipe 6 with air inlet pipe 6 closures; Cover 5 central authorities and have the first combustion gas air admission hole 8 keeping out the wind, the both sides up and down of this first combustion gas air admission hole 8 have the first air inlet hole 9; Described air inlet pipe 6 has on 5 end faces that are connected and the first combustion gas air admission hole 8 and the 9 corresponding second combustion gas air admission hole 10 and the second air inlet holes 11, the first air inlet hole with keeping out the wind to cover.The air inlet pipe 6 outer sheaths 7 that are arranged with, this sheath 7 is a frustum for the end of hollow circuit cylinder, close stove 1.Sheath 7 is positioned at little one section of air inlet pipe 6 diameters.

Operation principle of the present utility model is:

With the stalks of crops, rice husk, saw foam etc. is that the fuel gas with low heat value that produces of raw material is by flowing in air inlet pipe 6 through first and second combustion gas air admission hole 8,10 successively, undergauge transition position gas pressure increases in air inlet pipe 6, enter at last in the burner 3, by first and second combustion gas venthole 12,13 outputs; Because increased the venthole of combustion gas on the burner 3, therefore, the combustion gas of output can reach required calorific value.
