Wherein, column external furnace body 1, column inner furnace body 2, ring-type ring washer 3, air intake cylinder 4, support member 5, base plate 6, outer stove wind hole 11, ring washer holddown groove 12, external furnace body lug 13, external furnace body draw-in groove 14, wind hole, bottom 21, wind hole, top 22, inner furnace body lug 23, inner furnace body draw-in groove 24, ring washer lug 32, fresh air inlet 41, blower fan 42, opening 43, push rod 44, projection 45, support member draw-in groove 51, support member lug 52, socket 53.
The specific embodiment
As shown in Fig. 1 ~ 7, outdoor portable stove of the present invention, by column external furnace body 1, column inner furnace body 2, ring-type ring washer 3 and air intake cylinder 4, removably assembled, after dismounting, column external furnace body 1, column inner furnace body 2 and ring-type ring washer 3 can be rolled and put into air intake cylinder 4.Can also be provided with base plate 6, be positioned at below column external furnace body 1.
Column external furnace body 1 and column inner furnace body 2 are surrounded by rectangle or approximate rectangular (as approximate rectangular trapezoidal, parallelogram or other shapes) sheet metal.Sheet metal two ends can be fixing by external furnace body lug 13 and external furnace body draw-in groove 14, inner furnace body lug 23 and inner furnace body draw-in groove 24, and lug has groove 15, and lug is stuck in draw-in groove by groove 15.Sheet metal two ends can also be fixed by other means.
Outer stove wind hole 11 is established in column external furnace body 1 bottom.Air intake cylinder 4 one end are connected with outer stove wind hole 11, and the other end is provided with fresh air inlet 41.In air intake cylinder 4, be provided with blower fan 42, be preferably the blower fan with USB interface, blower fan can also connecting small-sized solar panel.Air intake cylinder 4 is provided with the push rod 44 in opening 43 and opening 43 near fresh air inlet 41 one end, to roll after column external furnace body 1, column inner furnace body 2 and 3 dismountings of ring-type ring washer to put into while taking out again after air intake cylinder 4, by push rod, release, air intake cylinder 4 arranges projection 45 at the other end, to block fixing in air intake cylinder 4 insertion outer stove wind holes 11.
Wind hole, some tops 22 is established on column inner furnace body 2 tops, wind hole, some bottoms 21 is established in bottom, the preferred diameter 1.5cm of wind hole, top 22(left and right) than the preferred diameter 0.5cm of wind hole, bottom 21(left and right) large, the air quantity that makes to enter wind hole, top is larger than the air quantity in wind hole bottom entering.Bavin (comprising wet bavin) is put into 2 burnings of column inner furnace body, the mezzanine space that air enters between column external furnace body 1 and column inner furnace body 2 through outer stove wind hole 11, portion of air enters column inner furnace body 2 from wind hole, top 22, portion of air directly enters in column inner furnace body 2 through wind hole, bottom 21, because wind hole 21, bottom is very little, column inner furnace body 2 bottom firewood burn incompletelys produce a large amount of carbon monoxide, carbon monoxide rises to top, the more hot-airs that enter with wind hole, top 22 mix, fully burning, produces larger flame.
Ring-type ring washer 3 is arranged between column external furnace body 1 and column inner furnace body 2 and is positioned at above wind hole, top 22.Column external furnace body 1 top is provided with ring washer holddown groove 12, and ring-type ring washer 3 is provided with ring washer lug 32, and ring-type ring washer 3 inserts ring washer holddown groove 12 by ring washer lug 32, is fixed in ring washer holddown groove 12.Can also be by other means that ring-type ring washer 3 is fixing.
At column external furnace body 1 and column inner furnace body 2 tops, at least three support members 5 are set, are used for placing pot.Support member 5 can be surrounded by rectangular metal sheet square, and sheet metal two ends are fixed by support member draw-in groove 51 and support member lug 52.In support member 5 lower ends, be provided with four sockets 53, be fixed on column external furnace body 1 and column inner furnace body 2.Support member 5 can also be tubulose (as titanium alloy pipe), and lower end is provided with four sockets.
As a preferred embodiment of the present invention, the parts such as column external furnace body 1, column inner furnace body 2, ring-type ring washer 3 are made by titanium alloy thin slice, and about 0.1mm is thick for thin slice; Air intake cylinder 4 diameter 3.5cm, are about 25cm.Be built into stove, the about 15cm of stove peripheral diameter, lightweight, sound construction.
When stove of the present invention carries, taken apart, all parts such as column external furnace body 1, column inner furnace body 2 launch to roll to put into air intake cylinder 4, are convenient for carrying, and during use, assembling is built into stove.
