The flame combustion apparatus that the present invention can change vortex kenel more comprises a cradle, and it is mounted on this second component one end away from this first component, and this cradle can connect a fuel tank, and this fuel tank can arrange a wick.
The flame combustion apparatus that the present invention can change vortex kenel more comprises a holder, a bracing frame and a base, this holder comprises a fixing hole and several fixing feet, this fuel tank can be positioned over this fixing hole, those fixing feet are stood in a plane for this holder, this bracing frame comprises an outer cover, one is held hole, a retainer ring and several support portion, this appearance hole is formed at this outer cover and holds this nozzle, this water conservancy diversion group, this guide ring, this cradle, this fuel tank and this holder, this retainer ring is formed radially several fixing hook part, those fixing hook parts are connected to this cover body, those support portions extend to form between this outer cover and this retainer ring, this base is arranged at this bracing frame away from one end of this cover body and comprises several foot.
The flame combustion apparatus that the present invention can change vortex kenel not only utilizes stack effect to form the effect of vortex flame with other hydrodynamic effect, and coordinates Coanda effect (Coanda Effect) to produce vortex flame significantly.So-called stack effect utilizes air heats to cause density to reduce, and makes the hot-air of generation increase in this cover body, and leave in this cover body one end away from this nozzle.Because one end of this cover body has an opening, can negative pressure be formed because hot-air falls apart excessive and will fill up in the restricted quarter of this cover body of air suction in the several tonifying Qi roads between this second component and this cradle, flame in the restricted quarter of this cover body by ascending air, namely so-called stack effect auxiliary and improve flame height.If make the air inlet entering this cover body rotate by various diversion mode just can make ascending air in the shape of a spiral, and then produce the effect of swirl flame.
The flow duct of path for providing extraneous air to import this cover body that the airtube of this water conservancy diversion group upwards extends, because the sectional area of those airtubes is little compared with the sectional area of this cover body, so when air enters those airtubes and enters in the restricted quarter of this cover body, can venturi-effect be produced and air be accelerated, air through accelerating can keep speed and upwards climb sharply, when the air filled into upwards is climbed sharply, flame will be driven to rotate and rise in the shape of a spiral simultaneously, improving flame height further.
But the height of the intensity of stack effect and this cover body, this cover body internal and external temperature gap, relevant with the degree entering this cover body air circulation.Generally when the scale of burning is less and when the cover body height of generation stack effect is shorter, stack effect dies down, when main cause is burning small scale, relative produced heat is also few, therefore cause this cover body upper and lower pressure reduction too low, in this case due to the water conservancy diversion insufficient strength of those airtubes, add the inertia of upper outlet body inner fluid itself, if the flow field therefore only relying on stack effect and guide functions cannot be formed in minimum distance to stablize spiral trend produce the effect of obvious swirl flame.
The present invention can change the flame combustion apparatus of vortex kenel except the stack effect using general swirl flame and guide functions, add and use Coanda effect (Coanda Effect), so-called Coanda effect refers to that the negative pressure formed by stack effect in this cover body sucks outside air, and with the blade of this water conservancy diversion group, importing air is spirally led the internal face of this cover body the air of suction.Viscosity due to air itself makes importing air draught have to depart from original flow direction and slightly turns to and be attached to the tendency of flowed through body surface.This is because viscosity makes to there is skin-friction force between the body surface that flows through, and the air-flow velocity flow through near body surface is slowed down, as long as the Curvature varying of the body surface that air-flow flows through is not too large, the slowing down of flow velocity can cause importing air and can be attracted on body surface and flow.But once flow velocity along flowing through the barometric gradient vanishing or negative of body surface, fluid be no longer attracted to body surface upper reaches movable property estranged from and supervene eddy current.Simultaneously by guiding cool ambient air spirally lead the internal face of this cover body time can produce centrifugal force, because cold air proportion is larger, air-guiding coordinates and centrifugal force makes Coanda effect in this cover body, continue longer stream distance, and then can maintain the flow field of comparatively stablizing spiral trend.The internal diameter of this pod apertures is finally coordinated to be less than the height of the pore size control flame of this pore, therefore this device coordinates above-mentioned multiple fluid effect under spark flame scale, still can form the flame effect obviously rotated when burning, and is that existing apparatus cannot be reached.
Technical characteristics of the present invention is: the present invention can change the flame combustion apparatus of vortex kenel except the stack effect using general swirl flame and guide functions, more add and use Coanda effect (Coanda Effect), so-called Coanda effect refers to that the negative pressure formed by stack effect in this cover body sucks outside air, and with the blade of this water conservancy diversion group, importing air is spirally led the internal face of this cover body the air of suction, make Coanda effect in this cover body, continue longer stream distance, and then can the flow field of comparatively stablizing spiral trend be maintained, and coordinate the internal diameter of this pod apertures to be less than the height of the pore size control flame of this pore, therefore this device coordinates above-mentioned multiple fluid effect under spark flame scale, still can form the flame effect obviously rotated when burning.
Secondary technical characteristic of the present invention is: this guide ring comprises several lamellar body and a drivening piece, curved and the storehouse and corral forms this pod apertures each other of each this lamellar body, the first component that this drivening piece is hubbed at this nozzle away from this second component one end and connect those lamellar bodies, this drivening piece can drive those lamellar bodies to move along a circumferencial direction of this pod apertures relative to the first component pivotable of this nozzle, those lamellar bodies are made optionally to change the internal diameter of this pod apertures close to or away from this pod apertures axial line, when user and device interactive, the internal diameter by a guide ring is only needed to change, the i.e. water conservancy diversion angle of the diversion air of adjustable outside introducing.Under identical burning scale, maintain except the effect of obvious swirl flame except the height that can change flame.More can change flame further and rotate kenel.The flame adjusted close to personal like rotates kenel, increases the enjoyment of device.
Other object, advantage and novel characteristics of the present invention will be more obvious from the following detailed description and related drawings.The record of this device measured result invests in annex, to prove that validity of the present invention is with unique.

The flame combustion apparatus that the present invention can change vortex kenel not only utilizes stack effect to form the effect of vortex flame with other hydrodynamic effect, and coordinates Coanda effect (Coanda Effect) to produce vortex flame significantly.So-called stack effect utilizes air heats to cause density to reduce, and makes the hot-air of generation increase in this cover body 40, and leave away from one end of this nozzle 10 at this cover body 40.Because one end of this cover body 40 has an opening 42, can negative pressure be formed because hot-air falls apart excessive and will fill up in this cover body 40 of air suction in the several tonifying Qi roads 51 between this second component 12 and this cradle 50, flame in the restricted quarter 41 of this cover body 40 by ascending air, namely so-called stack effect auxiliary and improve flame height.If make the air inlet entering this cover body 40 rotate by various diversion mode just can make ascending air in the shape of a spiral, and then produce the effect of swirl flame.
The flow duct of path for providing extraneous air to import this cover body 40 that the airtube 22 of this water conservancy diversion group 20 upwards extends, because the sectional area of those airtubes 22 is little compared with the sectional area of this cover body 40, so when air enters those airtubes 22 and enters in the restricted quarter 41 of this cover body 40, can venturi-effect be produced and air be accelerated, air through accelerating can keep speed and upwards climb sharply, when the air filled into upwards is climbed sharply, flame will be driven to rotate and rise in the shape of a spiral simultaneously, improving flame height further.
But the height of the intensity of stack effect and this cover body 40, this cover body 40 internal and external temperature gap and and to enter the degree of this cover body 40 air circulation relevant.Generally when the scale of burning is less and when the cover body 40 of generation stack effect is highly shorter, stack effect dies down, when main cause is burning small scale, relative produced heat is also few, therefore cause the pressure reduction of this cover body about 40 too low, in this case due to the water conservancy diversion insufficient strength of those airtubes 22, add the inertia of upper outlet body inner fluid itself, if the flow field therefore only relying on stack effect and guide functions cannot be formed in minimum distance to stablize spiral trend produce the effect of obvious swirl flame.
