Description

Technical Field

[0001] This utility model relates to a combustion device, and more particularly to a simple vortex flame combustion device. Background Technology

[0002] Please refer to Taiwan Patent No. TWI558950, "Flame Combustion Device with Modifiable Vortex Pattern," which describes a flame combustion device with a modifiable vortex pattern. The device includes a nozzle, a flow guide assembly, a flow guide ring, and a cover. The nozzle is connected to a fuel tank and has an air hole with a specific diameter. The flow guide assembly is disposed at the air hole of the nozzle and includes several blades. Each blade is spirally and uniformly distributed along a circumferential direction along the inner periphery of the air hole, forming an air passage between two adjacent blades. The flow guide ring is disposed at one end of the nozzle and has a flow guide hole communicating with the air hole. The flow guide hole has an inner diameter smaller than the diameter of the air hole. The cover is connected to one end of the nozzle and adjacent to the flow guide ring. The cover is light-transmitting and encloses a confined space that communicates with the flow guide hole of the flow guide ring.

Detailed Implementation

[0017] Please refer to Figures 1 to 3The figures shown are a perspective view, an exploded perspective view, and a cross-sectional view of the simplified vortex flame combustion device of this utility model. This utility model provides a simplified vortex flame combustion device 10, comprising a fuel container 20, a wick holder 30, at least one wick 40, and a windproof cover 50; wherein:

[0018] The fuel container 20 is provided with a fuel tank 21 that opens upwards.

[0019] The wick holder 30 is connected to the upper vertical edge of the fuel container 20. The wick holder 30 is provided with a central part 31 and several blades 32 integrally formed and connected to the central part 31. The several blades 32 are equally spaced around the outer periphery of the central part 31 in the horizontal direction.

[0020] The wick 40 is inserted into the center part 31. One end of the wick 40 is located in the fuel tank 21 and the other end protrudes from the side of the wick holder 30 opposite to the fuel container 20.

[0021] The windproof cover 50 is provided with an airflow channel 51 that extends vertically and connects the upper and lower edges of the windproof cover 50 and corresponds to the center part 31. The windproof cover 50 is connected to the candle holder 30 along its lower vertical edge.

[0022] The combustion device 10 includes a measuring cup 60, which is detachably connected to the upper vertical edge of the wind shield 50 by means of insertion into the airflow channel 51. When the measuring cup 60 is connected to the wind shield 50, the measuring cup 60 closes the opening of the airflow channel 51 at the top of the wind shield 50.

[0023] The candle holder 30 is provided with an outer ring 33 integrally formed and connected to the plurality of blades 32. The outer ring 33 surrounds the plurality of blades 32 and is connected to the fuel container 20. The upper edge of the outer ring 33 is vertically higher than the upper edge of the candle wick 40. The wind shield 50 is connected to the outer ring 33 along its lower vertical edge.

[0024] The plurality of blades 32 are respectively disposed on the upper vertical direction of the fuel tank 21. The outer ring 33 is provided with an air intake 331, which is disposed on the side of the plurality of blades 32 opposite to the central part 31 in the horizontal direction. Air can pass through the air intake 331 from the outside of the outer ring 33 and enter between any two of the plurality of blades 32.

[0025] The outer ring 33 has a flange 332 along its horizontal outer periphery. The wind shield 50 is fitted onto the outer ring 33 and abuts against the flange 332 along its vertical lower edge. The combustion device 10 includes a base 70, which has a receiving groove 71 that extends vertically through it. The fuel container 20 is disposed in the receiving groove 71. The flange 332 abuts against the upper edge of the base 70 along its vertical direction.

[0026] The fuel container 20 is connected to several locking members 22, which pass through the fuel container 20 and are fixed to the wick holder 30, so that the fuel container 20 is suspended in the receiving groove 71 through the wick holder 30.

[0027] In this embodiment, there are several candle wicks 40, which are inserted into the central portion 31 at equal intervals.

[0028] The combustion device 10, with its simple structure, can produce a spiral flame. When using the combustion device 10, the measuring cup 60 must first be removed. The air convection generated by the burning wick 40 allows external air to enter the airflow channel 51 through the blades 32. This airflow through the blades 32 forms a spiral trajectory, causing the flame of the burning wick 40 to be spiral-shaped. The wind shield 50 is made of transparent material, making the flame of the wick 40 easily visible. After use, the measuring cup 60 can be placed back on top of the wind shield 50, allowing the flame of the wick 40 to extinguish naturally. The measuring cup 60 can also be used as a fuel measuring tool when refilling fuel.
