Oil burning lamp

Abstract

An oil burning lamp comprises an oil container, a wick and a heating structure. The wick includes a first end located in the oil container to draw fragrance fuel oil therein, a second end to draw the fragrance fuel oil from the first end to be ignited for burning and a middle section interposed between the first end and second end. The heating structure is coupled on the wick and includes 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 to clamp the middle section of the wick, a diffusing portion to bridge the heat transfer portion and heating portion and a diffusing chamber located in the diffusing portion.

What is claimed is: 
     
         1 . An oil burning lamp, comprising:
 an oil container including an oil storage room to hold fragrance fuel oil and an opening leading to the oil storage room;   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.
