The present invention mainly discloses a flame burning device, and more particularly to a burning device capable of efficiently generating and changing a vortex flame.

Please refer to the "VORTEX TYPE GAS LAMP" patent of U.S. Patent No. 7,097,448, which discloses a scroll type gas lamp for combustible gas to generate an upward vortex flame, the vortex flame being located around It is limited to the boundary of the vortex air. During the operation, there is an interface between the vortex air without gas and the central region surrounded by gas, and the gas is burned inside. The gas lamp has an axis and includes: a base having a surface extending laterally along the central axis; a shield including a first and a second axially extending section Each block has an upper end and a lower end, and the lower end of each block is fluid-tightly coupled to the base, each block is almost identical and transparent, each block constitutes a cut-off wall, and the cut-off wall has an arc. An inner wall and an outer wall, each block having an axially extending first edge and an axially extending second edge; the first and second blocks Alternatingly overlapping and their edges are adjacent to each other and spaced apart to form tangentially oriented air ports, thus forming an axially extending chamber that is open to the sides due to the ports; the first and second blocks are It is arranged and arranged at the base and surrounds the entrance of the combustible gas; the gas combines with the air entering from the port for combustion, the burning gas forms a flame, the flame is separated from the curved inner wall, and the air does not allow the gas to flow to the port.

The shield of the aforementioned patent includes two opposite first and second blocks, the first block and the second block are all disposed on the base, and the two ends of the two blocks overlap each other to form a port, and the external air passes through the opposite The two ports enter the interior of the shroud and provide the air required for flame combustion by external air entrainment inside the shroud. Such a design can only provide continuous combustion of the flame, and is unstable in the practical application due to the influence of the air flow around the device, resulting in difficulty in maintaining a stable flame height and a vortex shape, and only in a certain range of the flame scale. Forming a rotating flame effect, if the flame scale is small or the length of the shield is not long enough, a significant rotating flame effect cannot be formed. Moreover, since the intake air flow of the device is in a fixed state, the size and length of the flame can only be adjusted by changing the combustion scale. At the same combustion scale, the flame rotation pattern cannot be changed. For the user, it is not possible to interact with the device and produce a flame rotation pattern that is close to personal preference.

The light transmissive cover is arranged in alignment, and the longitudinal position of the air hole is in an upright shape and is located in the body. When the outside air enters the interior of the transmissive cover via the obliquely aligned air holes, the air forms a swirling flow that provides the air required by the flame to allow the flame to continue to burn and form a rotating effect. However, since the air inlet is located on the plane and above the combustion port, the direction of the air intake is perpendicular to the direction of combustion of the flame, and the rotating flame effect can only be formed when the flame scale is large enough. If the flame scale is small, it cannot be formed obviously and stably. Rotating flame effect.

The present invention can change the vortex type flame combustion device to not only utilize the chimney effect with other fluid effects to form a swirling flame, but also to produce a distinct swirling flame in conjunction with the Coanda Effect. The so-called chimney effect is to reduce the density caused by the heat of the air, so that the generated hot air rises in the casing and exits at the end of the casing away from the nozzle. Because the cover has an opening at one end, a negative pressure is generated due to the overflow of hot air, and air of a plurality of air passages between the second component and the socket is drawn into the restricted space of the cover to fill The flame in the confined space of the enclosure increases the flame height by means of an updraft, also known as the chimney effect. When the intake air entering the cover body is rotated by various flow guiding means, the ascending air flow can be spiraled, thereby generating the effect of rotating the flame.

The upwardly extending path of the air guiding channel of the guiding group is a flow pipe for supplying external air into the cover body. Since the cross-sectional area of the air guiding channels is smaller than the sectional area of the cover body, when air enters the air guiding channels, the air enters When the cover body is in the confined space, a venturi effect is generated to accelerate the air, and the accelerated air will maintain the speed and rise upward. When the replenished air rises upward, the flame will be rotated and simultaneously The spiral rises to further increase the flame height.

However, the strength of the chimney effect is related to the height of the cover, and the temperature difference between the inside and outside of the cover is related to the degree of air circulation into the cover. Generally, when the combustion scale is small and the height of the shell body generating the chimney effect is short, the chimney effect is weakened, mainly because the combustion scale is small and the amount of heat generated is small, so that the pressure difference between the upper and lower sides of the shell is too low. In this case, because the guiding force of the air guiding channels is insufficient, and the inertia of the fluid itself in the casing is added, the flow field of the stable spiral rising trend cannot be formed in a very short distance by relying only on the chimney effect and the guiding effect. And produces a distinctly rotating flame effect.

The flame burning device of the present invention can change the vortex type flame combustion device, in addition to the chimney effect and the diversion effect of the general rotating flame, the Coanda effect is added, and the so-called Coanda effect means that the hood body is formed by the chimney effect. The negative pressure draws in the outside air, and the sucked air is guided by the blades of the flow guiding group to the inner wall surface of the casing in a spiral shape. Due to the viscosity of the air itself, the incoming air flow has a tendency to deviate slightly from the original flow direction and adhere to the surface of the object flowing therethrough. This is because the viscous surface friction between the surfaces of the flowing objects, and the flow velocity of the air flowing near the surface of the object is slowed down, as long as the curvature of the surface of the object through which the airflow flows is not too large, and the flow rate is slowed down. It will cause the introduced air to be adsorbed on the surface of the object. However, once the flow rate becomes zero or negative along the pressure gradient across the surface of the object, the fluid is no longer adsorbed on the surface of the object to create a separation and is accompanied by eddy currents. At the same time, centrifugal force is generated by guiding the outside cold air to guide the inner wall surface of the cover body in a spiral shape. Due to the large specific gravity of the cold air, the guiding air flow matching and the centrifugal force cause the Coanda effect to continue in the cover body for a long distance. In turn, it can maintain a relatively stable spiral upward flow field. Finally, the inner diameter of the guiding hole is smaller than the diameter of the air hole to control the height of the flame. Therefore, the device can cooperate with the multiple fluid effect to form a significantly rotating flame effect under a small flame scale during combustion, which is a conventional device. Unable to reach.

The main technical feature of the present invention is that the flame burning device of the present invention can change the vortex type flame combustion device in addition to the chimney effect and the diversion effect of the general rotating flame, and the Coanda Effect is added. The so-called Coanda effect is Refers to the negative pressure generated by the chimney effect in the cover body to take in the outside air, and the inhaled air is guided to the inner wall surface of the cover body by the blades of the flow guiding group in a spiral shape, so that the Coanda effect is in the cover body. Maintaining a longer flow distance, thereby maintaining a relatively stable spiral upward flow field, and matching the inner diameter of the flow guiding hole to the height of the air hole to control the height of the flame, so the device can cooperate with the above multiple fluid effects during combustion A very rotating flame effect can still be formed at a very small flame scale.

A secondary technical feature of the present invention is that the flow guiding ring includes a plurality of sheets and a driving member, each of the sheets is curved and stacked on each other to form the guiding hole, and the driving member is pivoted on the The first part of the nozzle is away from one end of the second part and is connected to the pieces, the driving piece being pivotable relative to the first part of the nozzle and driving the pieces to move in a circumferential direction of the flow guiding hole, so that The sheets are selectively adjacent to or away from an axial line of the flow guiding hole to change the inner diameter of the guiding hole. When the user interacts with the device, only the inner diameter of one guiding ring needs to be changed, that is, The flow angle of the externally introduced diversion air can be adjusted. At the same combustion scale, in addition to changing the height of the flame and maintaining the effect of a distinctly rotating flame. The flame rotation pattern can be further changed. Adjust the flame rotation pattern close to your personal preference and increase the fun of the device.

The present invention can change the vortex type flame combustion device to not only utilize the chimney effect with other fluid effects to form a swirling flame, but also to produce a distinct swirling flame in conjunction with the Coanda Effect. The chimney effect is that the density of the air is lowered by heating, so that the generated hot air rises in the casing 40 and exits at the end of the casing 40 away from the nozzle 10. Since the cover 40 has an opening 42 at one end, a negative pressure is generated due to the overflow of hot air, and the air of the plurality of air passages 51 between the second member 12 and the holder 50 is drawn into the cover. Filled within 40, the flame in the confined space 41 of the shell 40 increases the flame height by the updraft, which is the aid of the so-called chimney effect. When the intake air entering the cover 40 is rotated by various flow guiding methods, the ascending air current can be spiraled, and the effect of rotating the flame is generated.

The upwardly extending path of the air guiding passage 22 of the flow guiding group 20 is a flow duct for supplying external air into the casing 40. Since the cross-sectional area of the air guiding passages 22 is smaller than the sectional area of the casing 40, when air enters the When the air guiding passages 22 enter the confined space 41 of the cover 40, a venturi effect is generated to accelerate the air, and the accelerated air will maintain the speed and rise upwards, when the replenished air rises upward, The flame will be rotated and spiraled at the same time to further increase the flame height.

However, the strength of the chimney effect and the height of the cover 40, the temperature difference between the inside and the outside of the cover 40 is related to the degree of air flow into the cover 40. Generally, when the combustion scale is small and the height of the hood 40 which generates the chimney effect is short, the chimney effect is weakened, mainly because the combustion scale is small relative to the amount of heat generated, and thus the pressure difference between the upper and lower sides of the hood 40 is caused. Too low, in this case, because the guiding force of the air guiding channels 22 is insufficient, and the inertia of the fluid itself in the casing is added, the stable spiraling tendency cannot be formed in a very short distance if only the chimney effect and the guiding effect are relied on. The flow field produces an effect of a distinctly rotating flame.

The flame burning device of the present invention can change the vortex type flame burning device, in addition to the chimney effect and the diversion effect of the general rotating flame, the Coanda effect is added, and the so-called Coanda effect means that the shell 40 is surrounded by a chimney. The negative pressure formed by the effect draws in the outside air, and the sucked air is guided to the inner wall surface of the cover 40 in a spiral shape by the blades 21 of the flow guiding group 20. Due to the viscosity of the air itself, the incoming air flow has a tendency to deviate slightly from the original flow direction and adhere to the surface of the object flowing therethrough. This is because the viscous surface friction between the surfaces of the flowing objects, and the flow velocity of the air flowing near the surface of the object is slowed down, as long as the curvature of the surface of the object through which the airflow flows is not too large, and the flow rate is slowed down. It will cause the introduced air to be adsorbed on the surface of the object. However, once the flow rate becomes zero or negative along the pressure gradient across the surface of the object, the fluid is no longer adsorbed on the surface of the object to create a separation and is accompanied by eddy currents. At the same time, centrifugal force is generated by guiding the outside cold air to guide the inner wall surface of the cover 40 in a spiral shape. Since the cold air has a large specific gravity, the guiding airflow and the centrifugal force cause the Coanda effect to last longer in the cover 40. The flow distance, in turn, can maintain a relatively stable spiral upward flow field. Finally, the inner diameter D1 of the air guiding hole 31 is smaller than the diameter D of the air hole 13 to control the height of the flame. Therefore, the device can cooperate with the multiple fluid effect to form a significantly rotating flame effect under a small flame scale. It is impossible to achieve with existing devices.

Please refer to FIG. 8 , which is a schematic diagram of the use of a second embodiment of a flame burning apparatus capable of changing a scroll type according to the present invention, and in conjunction with FIG. 7 , the structure of the second embodiment of the flame burning apparatus of the scroll type can be changed. It is substantially the same as the first embodiment except that the inner diameter D2 of the guide ring 30a of the second embodiment is larger than the inner diameter D1 of the guide ring 30 of the first embodiment. In the present embodiment, the inner diameter D2 is 51.6mm. Thereby, the flame height generated in the second embodiment is higher than the flame height generated in the first embodiment.

The plurality of second connecting portions 332b are evenly distributed in the circumferential direction of the ring portion 331b and surround the through hole 333b.

The 334b is formed by the ring portion 331b extending radially and is pivotable relative to the first member 11 of the nozzle 10 for a user to move the pieces 32b, thereby adjusting the inside of the guiding hole 31b.
