BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a torch and more particularly to a solid fuel torch having a flame collector which is adapted for centralizing flames of the torch and increase height of the flames.

2. Description of the Related Art

Camping and picnics often include a torch. Many individuals enjoy staying around a torch, especially in the evening when it becomes cool.

Outdoor fireplaces are well-known in the art, and are generally used to provide outdoor heat and/or to provide an aesthetically appealing appearance of a wood fireplace. Various prior art outdoor fireplaces are illustrated, for example, in Taiwan Pat. No. 094217780.

While the outdoor fireplaces of the prior art provide a number of advantageous features, they nevertheless have certain limitations. As described herein, the present invention seeks to overcome certain of these limitations and other drawbacks of the prior art, and to provide new features not heretofore available.

Moreover, solid wax, coal oil and gas are usually used as source with the conventional torch; but unstable characteristics of coal oil and gas often cause the safety problems. Comparatively, solid wax is safer while burning. Cotton wick is arranged in the center of the solid wax, however, the conventional cotton wick often seems to have disproportionately small diameter as to have some disadvantages as follows:

Solid wax would be dissolved in 80 degrees Centigrade and soaked by the cotton wick. During burning, the solid wax is decreased and the height of cotton wick is getting lower so that the height of the flames can not be maintained like the very start.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a solid fuel torch including a flame collection allowing flames of the torch burning steadily and increasing the height of the flames. The torch further includes a stand having a containing portion, with the containing portion adapted for receiving a solid fuel means. The solid fuel means has a wick protruding from solid fuel, with diameter of the wick larger than the one eighth diameter of the solid fuel. The flame collection is mounted on the solid fuel means and includes an enclosed barrel and a casing means. The enclosed barrel is disposed in the containing portion, and a channel is defined between the solid fuel means and the enclosed barrel, with the channel having a premeditated width. The casing means includes a main body and a guiding portion piercing the main body, with a central channel defined in the guiding portion and communicating with the solid fuel means.

A feature to the present invention is that the guiding portion of the casing means is in form of a hollow awl and includes a first end and a second end, with the first end of the guiding portion above the top of the main body of the casing means, with the second end of the guiding portion below the top of the main body of the casing means. A plurality of apertures are provided on the second end of the guiding portion and adapted for guiding air into the central channel of the casing means as to increase the height of flames. And the awl guiding portion pressurizes the guided air as to centralize the flames.

Other objectives, advantages, and features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

An embodiment of the present invention will now be discussed with reference to FIGS. 1 through 5. As shown in FIGS. 1 through 4, a solid fuel torch include s a stand 10, a solid fuel means 20 and a flame collector mounted on th e solid fuel means 20. The solid fuel means 20 and the flame collector are both disposed on the stand 10.

The stand 10 consists of numbers of stand legs 101, numbers of first stand rings 102, a stand spike 103 and two second stand rings 104. The second stand rings 104 have different diameters with respect each other. Each stand leg 101 has a first end and a second end. To form the stand 10, firstly, bend the first end of each stand leg 101 to form the first end of each stand leg 101 to be L-shaped. And then, the first end of each stand leg 101 includes a bent portion 105 and a distal portion 106, with the bent portion 105 approximately perpendicular to the related stand leg 101, with the distal portion 106 approximately perpendicular to the related bent portion 105. Secondly, set the larger second stand rings 104 on the distal portion 106 of each stand legs 101, and evenly arrange the stand legs 101 around the larger second stand rings 104. Thirdly, set the smaller second stand rings 104 onto the bent portions 105. Moreover, the second stand rings 104 are welded with the stand legs 101 respectively. The first ends of the stand legs 101 and the second stand rings 104 define a containing portion 11 adapted for receiving the solid fuel means 20. The stand spike 103 is installed to the second ends of the stand legs 101 for inserting into the ground for anchoring the solid fuel torch (shown in FIG. 5). The first stand rings 102 are surrounded with the stand legs 101 and disposed on the stand 10 in position.

The solid fuel means 20 includes a metal can body 21 containing solid fuel (not numbered) and a wick 22 provided in the center of the solid fuel and protruding from a top surface 23 of the solid fuel. In this embodiment, the solid fuel is solid wax preferably. A thin solid wax is provided on the surface of the wick 22 for facilitating light up the wick 22. A diameter of the wick 22 is larger than the one eighth diameter of the solid fuel preferably.

The flame collector that is provided for covering the solid fuel means 20 includes an enclosed barrel 30, a casing means 40 and an air shield means 50.

The enclosed barrel 30, which is made of metal and defines a mesh portion 31, is removably disposed in the containing portion 11 and limited by the second stand rings 104. The enclosed barrel 30 surrounds the solid fuel means 20, and a channel 32 is defined between the can body 21 and the enclosed barrel 30, with the channel 32 having a premeditated width. Air can be guided from either the mesh portion 31 or the bottom of the channel 32 for combustion-supporting of the wick 22 of the solid fuel means 20.

The casing means 40 consists of a guiding portion 41 and a main body 42, with the guiding portion 41 disposed in the center of the main body 42 and welded with the main body 42. The main body 42 is in form of hollow lid and has a top surface 401 and a sidewall 402, with the bottom of the sidewall 402 slightly bent outwardly. The guiding portion 41 has a first end and a second end, with the first end provided to extend from a top surface of the main body 42, with the second end provided in the main body 42. The guiding portion 41 is preferably shaped like an awl in this embodiment, with inner diameter of the guiding portion 41 increasing from the first end of the guiding portion 41 to the second end of the guiding portion 41; however, the guiding portion 41 also can be shaped like a cylinder with an equal inner diameter. A central channel 411 is defined through the guiding portion 41 longitudinally, and numbers of apertures 412 are arranged annularly on the second end of the guiding portion 41, with the apertures 412 in communication with the central channel 411. In use, the main body 42 of the casing means 40 is mounted on the top of the enclosed barrel 30, and the second end of the guiding portion 41 is exactly above the wick 22. And top 221 of the wick 22 is slightly inserted into the central channel 411, with the distance between the top 221 of the wick 22 and the top surface 23 of the solid fuel is larger than the distance between bottom portion 413 of the second end of the guiding portion 41 and the top surface 23 of the solid fuel. Therefore, The bottom portion 413 of the second end of the guiding portion 41 is away from the top surface 23 of the solid fuel, with the top 221 of the wick 22 and a gap 43 is defined between the second end of the guiding portion 41 and the top surface 23 of the solid fuel. Therefore, the air guided from either the mesh portion 31 or the bottom of the channel 32 is split to flow through either the gap 43 or the apertures 412 into the central channel 411. The split air which flows through the gap 43 is provided to supply the wick 22 combustion-supporting gas, oxygen, so that the wick 22 can continue to burn. The split air is pressurized while flowing through the apertures 412 as to increase the height of flames A of the wick 22. Moreover, while the flames A move upwardly through the central channel 411, because the inner diameter of the first end of the guiding portion 41 is smaller than the second end of the guiding portion 41, the central channel 411 pressurizes and centralizes the flames A.

The air shield means 50 is hollow and formed via rolling up a metal plate. The air shield means 50 is removably mounted on the casing means 40, and the bottom of the air shield means 50 is abutted with the bottom of the sidewall 402 of the casing means 40 for securely installation of the air shield means 50 and the casing means 40. The air shield means 50 is wind proof as to prevent height of the flames A decreasing by wind and destroying the structure of the flames A. Numbers of pattern holes 51 are annularly arranged on the wall of the air shield means 50 for aesthetics. The pattern holes 51 are in form of variable-geometry or characters and provided near the top of the air shield means 50. Numbers of adjusting holes 52 are annularly arranged on the wall of the air shield means 50. The adjusting holes 52 are in form of bar and provided near the bottom of the air shield means 50. A piece 53 is installed onto the exterior of each adjusting hole 52 and operated to adjust the size of opening of the related adjusting hole 52 so that users can peep the interior of the air shield means 50 via the adjusting holes 52. Further, the air shield means 50 can be in form of transparent glass so that user can directly peep the interior of the air shield means 50 via the wall of the air shield means 50. The transparent glass can be multicolored for aesthetics.

A cap means 60 is provided to extinguish the flames A and includes a handle 61 and a hanging portion 62. The handle 61 is connected to the exterior of the cap means 60, and the hanging portion 62 is formed from the distal end of the handle 61 for hanging to the stand 10 in position (shown in FIG. 5). The handle 61 is in form of L-shaped. A inner diameter of the cap means 60 corresponds to the diameter of the first end of the guiding portion 41 so that while desiring to extinguish the flames A, users can grip the handle 61 to drive the cap means 60 to mount on the first end of the guiding portion 41.
