Abstract
A safe combustion device includes a housing. A wick is disposed in the housing. The wick has a top end at a first distance from a bottom surface of the housing. A guiding device is connected to the housing and includes at least one shade. The at least one shade has bottom and top sides at second and third distances from the bottom surface of the housing respectively. The second distance is shorter than the first distance. The first distance is shorter than the third distance. The at least one shade has an inner lateral side adjacent to the wick. The at least one shade and the housing include a flow passage formed therebetween.
Claims17
A safe combustion device comprising:
- a housing defining a receiving space;
- a wick disposed in the receiving space, with the wick having a top end at a first distance from a bottom surface of the housing;
- and
- a guiding device connected to the housing and including at least one shade, with the at least one shade having bottom and top sides at second and third distances from the bottom surface of the housing respectively, with the second distance shorter than the first distance, with the first distance shorter than the third distance, with the at least one shade having an inner lateral side adjacent to the wick and an outer lateral side opposite the inner lateral side, with the at least one shade and the housing including a flow passage formed therebetween, with the flow passage having a length between the inner lateral side of the at least one shade and the wick, a length below the bottom side of the at least one shade, and a length outside the outer lateral side of the at least one shade, wherein the guiding device includes at least one flow guiding member extending in the flow passage and disposed between the wick and the at least one shade, and wherein the at least one flow guiding member extends gradually upward and has a first end adjacent to the wick with the first end at a lower height than the top end of the wick from a bottom of the flow passage and a second end adjacent to the at least one shade at a higher height than the height of the first end from the bottom of the flow passage, wherein the at least one flow guiding member includes at least one orifice extending therethrough.
