Manual ignition security is greatly improved, without using expensive electrically-controlled valve.Fuel in this fuel tank 50 passes through this joint 23 Perforation 231 with this venthole 21 enter this cover body 30 restriction space 31 to produce vortex flame, user by igniter by This mutual pivot of burner two support body 11 is put and is formed an opening, and that is, the side of this burner is close to this nozzle 20 simultaneously point Fire, it is to avoid danger is caused by the top igniting of this burner.

The present invention have security manual ignition vortex flame combustion apparatus secondary be technically characterized in that not merely with Stack effect forms the effect of vortex flame with other hydrodynamic effect, and coordinates Coanda effect (coanda Effect) produce significantly vortex flame.So-called stack effect is to lead to density to reduce using air heats, makes the heat of generation Air rises in this cover body 30, and leaves away from one end of this nozzle 20 in this cover body 30.Because one end tool of this cover body 30 There is an opening, negative pressure can be formed because of scattered the overflowing of hot-air and fill up in this cover body 30 of air suction, the restriction of this cover body 30 Flame in space 31 by ascending air, that is, the auxiliary of so-called stack effect and improve flame height.Pass through each again Planting diversion mode makes the air inlet rotation of this cover body 30 of entrance just can make ascending air in the shape of a spiral, and then produces the effect of swirl flame Really.

The upwardly extending path of airtube 14 of this water conservancy diversion group 10 imports the flow duct of this cover body 30 for providing extraneous air Road, because the sectional area of those airtubes 14 is little compared with the sectional area of this cover body 30, so enter those airtubes 14 when air and When entering in the restriction space 31 of this cover body 30, venturi-effect can be produced and so that air is accelerated, accelerated air can keep Speed and climb sharply upwards, when the air filling into is climbed sharply upwards, it will drive flame rotation and rise in the shape of a spiral simultaneously, enter one Step improves flame height.

But the height of the intensity of stack effect and this cover body 30, this cover body 30 internal and external temperature gap and enter this cover body The degree of 30 air circulations is relevant.When general shorter with cover body 30 height producing stack effect when the scale of burning is less, cigarette Chimney effect dies down, and main cause is that during burning small scale, relatively produced heat is also few, and this cover body therefore caused is about 30 Pressure reduction too low, in this case due to the water conservancy diversion insufficient strength of those airtubes 14, add fluid itself in cover body 30 Inertia, if therefore only rely on stack effect and guide functions cannot form the flow field stablizing spiral trend in minimum distance And produce the effect of obvious swirl flame.

The vortex flame combustion apparatus that the present invention has security manual ignition remove the chimney effect with general swirl flame Should with guide functions outside, add and use Coanda effect (coanda effect), so-called Coanda effect refer in this cover body 30 by The negative pressure that stack effect is formed sucks outside air, and the air of suction is made importing air by the blade 12 of this water conservancy diversion group 10 Spirally guide the internal face of this cover body 30.Deviate original stream because the viscosity of air itself makes importing air draught have Dynamic direction and slightly turn to and be attached to the tendency of flowed through body surface.This be due to viscosity make the body surface that flows through it Between there is skin-friction force, and so that the air-flow velocity flowing through near body surface is slowed down, as long as the body surface that air-flow is flowed through Curvature varying be not too big, the slowing down of flow velocity can lead to import air and can be attracted to flowing on body surface.But once Flow velocity along flow through the barometric gradient vanishing of body surface or negative when, fluid be no longer attracted to body surface upstream movable property estranged From and supervene vortex.Simultaneously by guiding cool ambient air spirally guide this cover body 30 internal face when can produce from Mental and physical efforts, because cold air proportion is larger, so that Coanda effect is continued in this cover body 30 longer for guiding air-flow cooperation and centrifugal force Stream is away from and then maintaining the flow field relatively stablizing spiral trend.Therefore this device coordinates above-mentioned multiple fluid effect in burning Should be able to remain to form the flame effect of obvious rotation under spark flame scale, be that existing apparatus cannot be reached.

What said above, only presently preferred embodiments of the present invention, are not limited to the model of present invention enforcement Enclose, Qi Taru: the transition regime such as nozzle, shape of water conservancy diversion group, or blade kenel change, also all scope of the invention it In；Therefore be familiar with equivalent done by those skilled in the art of this technology or easily change, the spirit without departing from the present invention with The impartial change made under scope and modification, all should be covered by protection domain of the presently claimed invention.
