Description
- The present invention relates to an oil burning lamp and particularly to an oil burning lamp to provide improved evaporation of fragrance fuel oil.
- Lamp sets capable of emanating fragrances have been made in a wide variety of styles. For instance, perfume candles available in the past commonly include a wick which can be ignited to produce flame to heat and melt solid candle into wax vapor to emanate fragrances. However, most essences contained in the wax cannot exude fragrance as desired when burned. Only a small portion of the essences produce scanty fragrance when the wax near the flame has been heated and melted. Hence the effectiveness of the fragrance candles to emanate fragrance is limited.
- A conventional liquid type fragrance candle, referring to

The wick 7 can be burned to heat themetal heating head 6 to emanate fragrance. Themetal heating head 6 directly receives heat and can reach above Celsius 100.degree. and results in overheat of the wick and scorching of the fuel oil to generate charred smell. Moreover, the fuel oil is directly burned via the flame and cannot effectively produce fragrances. - To remedy the aforesaid drawbacks, U.S. Pat. No. 6,960,320 discloses an oil burning lamp that includes a burner tube to hold a wick. The burner has one end threaded through by the wick outwards for burning that generates heat transferred downwards to increase heating area of the wick. The burning tube further has a plurality of brackets with gaps formed thereon to expose the wick to the indoor ambience, thereby can diffuse fragrance outwards. However, the burner tube is directly in contact with the wick, and the high temperature of the burner tube easily excessively burns the essence in the wick to produce charred smell. Moreover, the burner tube only has a few slots to expose and communicate the wick with outer space. It is not an effective fragrance emanation technique.
- The primary object of the present invention is to solve the disadvantages of the conventional techniques of heat transfer structure that cannot effectively emanate fragrance in the air.

a wick running through the opening and containing a first end extended into the oil storage room to dip into the fragrance fuel oil, a second end to draw the fragrance fuel oil from the first end and be ignited for burning and a middle section located between the first end and the second end to allow the fragrance fuel oil to pass through; and
a heating structure coupled on the wick and including a heat transfer portion coupled annularly on the second end to get heat energy generated by burning of the fragrance fuel oil, a heating portion clamping the middle section, a diffusing portion bridging the heat transfer portion and the heating portion to transfer the heat energy from the heat transfer portion to the heating portion and a diffusing chamber located between the diffusing portion and the wick, the diffusing portion including at least one aperture leading to the diffusing chamber, the heating portion receiving the heat energy from the heat transfer portion via the diffusing portion to heat the middle section to facilitate evaporation of the fragrance fuel oil into the diffusing chamber so that vaporized fragrance fuel oil emanates to the exterior via the aperture.
2. The oil burning lamp of claim 1 further including a first cap fastened to the opening and a second cap stacked coaxially onto the first cap, the first cap and the second cap including respectively a first track and a second track on a lateral side corresponding to and engageable with each other to allow the first cap to turn coaxially against the second cap.
3. The oil burning lamp of claim 2 , wherein the first cap and the second cap include respectively a plurality of first air vents and a plurality of second air vents corresponding to each other.
4. The oil burning lamp of claim 2 , wherein the first cap and the second cap include respectively a first hole and a second hole that are overlapped and run through by the second end of the wick.
5. The oil burning lamp of claim 1 , wherein the heating portion is coupled on the opening and includes a hole run through by the wick to form clamping thereof.
6. The oil burning lamp of claim 1 , wherein the heat transfer portion and the diffusing portion include respectively a first fastening portion and a second fastening portion that are engageable with each other.
7. The oil burning lamp of claim 1 , wherein the heating portion and the diffusing portion include respectively a first coupling portion and a second coupling portion to couple with each other.
8. The oil burning lamp of claim 1 , wherein the heat transfer portion includes a support tube to hold the second end of the wick.
9. The oil burning lamp of claim 1 , wherein the heat transfer portion includes a coupling tube to couple with the second end of the wick.
10. The oil burning lamp of claim 1 , wherein the heating structure includes a heating coil in the diffusing chamber run through by the middle section of the wick.
11. The oil burning lamp of claim 10 , wherein the heating coil is connected to the heating portion.
12. The oil burning lamp of claim 10 , wherein the heating coil is connected to the heat transfer portion.
13. The oil burning lamp of claim 1 further including a protective cap to encase the heating structure.
