Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a combustion wick used in a combustion instrument using kerosene or the like as a fuel.

<Prior art> The combustion wick used in the combustion equipment is a cloth-like body made of cotton, polyester, or other fibers or filaments arranged on the upper end of the fuel sucking section made of glass or other non-combustible material. The one in which a combustion part made of a characteristic fiber is connected is used, and the above-mentioned suction part makes the fiber direction coincide with the fuel suction direction for the purpose of improving the suction of fuel.

<Problems to be Solved by the Invention> As described above, by making the fiber direction of the fuel suction section coincide with the fuel suction direction, the object of improving the fuel suction was achieved, but such a fuel suction section is I have a weak waist. Also, at the lower end of the suction part, there are usually multiple vertical cuts so that the hem is widened in the oil storage chamber, but this cut cuts the fibers aligned in the vertical direction, and the cut ends are blurred. As a result, there is a drawback in that it mixes into the fuel oil in the oil chamber and deteriorates the suction of the fuel, or it adheres to the inner wall of the combustion cylinder and the vertical movement of the wick becomes unsmooth.

<Means for Solving the Problems> In order to solve the above-mentioned drawbacks of the conventional combustion wick, the present invention has a fiber direction of the long fiber layer, which is the main part of the fuel sucking section, in a transverse direction perpendicular to the fuel sucking direction. Direction, and the irregular fiber cloths in which the fiber directions are irregularly intersected are stacked on both sides or one side, and are integrally connected with the long fiber layer by appropriate means, so that the hem spreads in the oil storage chamber. It has one or more vertical cuts.

<Operation> The long fiber layer mainly composed of transverse long fibers at right angles to the fuel suction direction strengthens the rigidity of the combustion core, and the fuel flow resistance increases to increase the fuel retention in the suction part. Lubrication to the combustion section will be smooth, the combustion condition will be good, and even if the transverse long fibers are cut by the cut provided at the lower end, fine fibers will not be loosened from the cut, and the long cut The fibers are securely held by the irregular fiber cloth or the braided yarn, and a good combustion state can be maintained for a long time.

<Embodiment> FIGS. 1 to 3 show an embodiment according to the present invention, in which a fuel suction portion b is connected to the lower end of a combustion portion a made of glass fiber or other noncombustible fiber by sewing or other means. Is
A vertical cut c having an appropriate width is formed at the lower end of the suction portion.

Although the above-mentioned structure is the same as the conventional one, in the present invention, the fuel suction part b is a thick fiber made by arranging synthetic fibers such as cotton fiber, nylon, polyester, polyethylene, polypropylene or the like or a mixture thereof in parallel. The filamentous filaments are arranged in a transverse direction at right angles to the fuel suction direction, and the braided filaments 2 arranged at appropriate intervals are used to form a cloth-like filamentous layer 3 having a required thickness on both sides or one side thereof. An irregular fiber cloth 4 in which the fiber directions are irregularly crossed, for example, a non-woven fabric is polymerized and integrally bonded with the long fiber layer 3 by needle punching or stitch bonding, and a non-combustible fiber such as glass fiber at the upper end. The burning part a consisting of the above is sewn and the plate-like one having the cut c at the lower end is left as it is or the both ends are sewn 5 as shown in FIG. 1 to form a tubular body.

As shown in FIG. 4, the long fiber layer 3 in which the fibers of the above filaments are arranged and braided is entangled with each other to form a cotton-like shape 6 having a required thickness, and the fiber direction is the fuel suction direction. The nonwoven fabric 4 may be polymerized on both sides or one side so as to be in a transverse direction at a right angle, and integrally bonded by means such as needle punching or stitch bonding. In this case, the braided yarn 2 may be omitted. it can.

The wick of the present invention and a hem of a wicking section in which a cloth-like body made of synthetic fiber has a fiber direction parallel to the fuel oil wicking direction and several stitch threads arranged at equal intervals in a lateral direction perpendicular to the fiber direction. As a result of an experiment using a mixed fuel of 70% white kerosene and 30% light oil, a conventional combustion wick in which a combustion section made of non-combustible fiber was connected to the upper end with a vertical cut was 30 In about 50 hours, tar and carbon adhere to the upper end of the combustion section to deteriorate the combustion state and reduce calories by about 20%,
While short fibers were found to be mixed in the oil chamber, the combustion wick according to the present invention did not cause combustion failure for 80 to 200 hours, and did not cause deformation or fiber loosening.

<Advantages of the Invention> The present invention is configured as described above, and the fiber direction of the long fiber layer 3 which is the main component of the fuel suction section is set to the transverse direction at right angles to the fuel suction direction, thereby increasing the resistance to the flow of fuel oil. Therefore, as compared with the conventional one, the fuel holding property is improved, the fuel is smoothly supplied to the combustion section a, and a good combustion state can be maintained.

In addition, the long fiber layer in which the fibers are arranged in the lateral direction has its shape secured by the irregular fiber cloth 4 or the braided yarn 2 integrally connected to the same layer, which makes the waist stronger and moves up and down the core. Combustion can be adjusted accurately and the shape of the long fiber layer 3 can withstand long-term use. Even if the fiber of the long fiber layer 3 is cut by the cut c below the suction part, the cut fiber is the non-woven fabric 4 or the braided yarn 2. Since it is held, there is no risk that fibers will be unraveled in the fuel oil during use or that it will stick to the inner wall of the combustion tube and make the vertical movement of the core unsmooth, so that it can be used in a good combustion state for a long time. it can.
