Each wire harness is composed of a plurality of wires. Thus, the fuel can be conveyed between the two ends of the capillary structure due to the action of the capillary phenomenon.

Description

Metal lamp wick

Technical Field

The present invention relates to a wick structure, and more particularly, to a wick structure woven from metal wires.

Background

The prior lamp is provided with a high-temperature resistant tray body above the fuel cup, and a rope-shaped cotton wick is arranged on the tray body in a penetrating way, so that the wick can be hung in the fuel cup. The cotton wick absorbs the fuel oil in the fuel oil cup by capillary phenomenon, and the top end of the wick is ignited by flame, so that the fuel oil can be burnt. However, the cotton wick is in a rope shape formed by weaving cotton, and the tail end is easy to scatter and is not easy to penetrate through the disc body when being cut off. And the cotton wick is easy to generate carbonization at the top when burning fuel oil, which is not beneficial to burning.

In addition, if the cotton wick is used with fuel oil with a slightly high viscosity, the adsorbability of the cotton wick is relatively reduced compared with the fuel oil with a high viscosity, and the flame is not easy to ignite or is extinguished shortly after ignition, so that the cotton wick cannot achieve the effect of stable and continuous ignition when used with the fuel oil with a slightly high viscosity, and the cotton wick has a poor oil absorption effect, easily generates a large amount of smoke, and causes environmental pollution.

Moreover, the core part of the cotton yarn wick is not fine enough, so carbon deposition is easily caused during combustion, the ignited flame is unstable, the carbon deposition is not easy to ignite when being too much, and the carbon deposition of the cotton yarn wick can cause abnormal combustion and easily cause danger if being too full when fuel is added.

Therefore, there are the patent publication No. 493722 of Taiwan patent publication No. 493722 of Wick structure and the patent publication No. 580106 of Taiwan patent publication No. 580106 of Wick structure improvement for oil lamp or alcohol lamp, both of which use glass fiber to improve the disadvantages of cotton wick, but there are many disadvantages to improve the glass fiber wick. First, from the manufacturing point of view, the material cost of the glass fiber is high, and the process of weaving the glass fiber and the cotton thread is complicated, so that the selling price of the glass fiber wick must be correspondingly increased, and the wick is a large amount of consumable, so that the consumer cannot provide a price for the parent. Furthermore, from an environmental standpoint, fiberglass has the potential for direct or indirect impairment of cardiopulmonary function, either to the user or to the manufacturer on site.

In fact, the glass fiber wick is carbonized when burning fuel, but the carbonization speed is slower than that of the cotton wick. Therefore, the height of the wick needs to be adjusted or fuel needs to be added according to the carbonization of the wick. Furthermore, the glass fiber wick has a problem of drooping after absorbing fuel oil by capillarity, and it is difficult for a user to adjust the height of flame, which is a problem that is difficult to overcome when the glass fiber wick is used in an ornamental lamp.

Detailed Description

Fig. 1 is an external view of a metal wick according to a first embodiment of the present invention. Fig. 2 is an enlarged partial schematic view of the metal wick shown in fig. 1. Fig. 3 is a schematic view of the use of the metal wick shown in fig. 1. Fig. 4 is a schematic cross-sectional view of fig. 3. Referring to fig. 1 to 4, the metal wick 1 of the present embodiment includes a hollow chamber 10 and at least one capillary structure 20.

In the present embodiment, the number of the capillary structures 20 is one, and the capillary structure 20 surrounds the hollow chamber 10 and is formed by weaving a plurality of

metal wire bundles

21 and 22 into a circular tube shape, so that the capillary structure 20 has flexibility and can be bent.

The plurality of metal wire harnesses includes a plurality of first metal wire harnesses 21 and a plurality of second metal wire harnesses 22 which are interlaced with each other, and each of the first metal wire harnesses 21 and at least one of the plurality of second metal wire harnesses 22 are interlaced with each other to form an acute angle θ. Therefore, the plurality of first metal wire harnesses 21 and the plurality of second metal wire harnesses 22 are interlaced with each other to form a plurality of meshes 23, and each mesh 23 has an acute angle θ. Each first wire harness 21 and each second wire harness 22 are respectively composed of a plurality of

wires

211, 221, and the

wires

221, 221 can be made of copper, stainless steel or composite metal material and have the same wire diameter. According to the flame reaction, the color of the ignited flame can be adjusted by changing the material of the wires 221, for example: the

wires

221, 221 are made of copper and can be ignited to produce a green flame.

Referring to fig. 3, since the capillary structure 20 is flexible and bendable, the top end of the metal wick 1 for igniting flame and the bottom end for sucking fuel are not limited to two longitudinally different ends as the conventional wick. The capillary structure 20 can be bent from the middle and then inserted into the fuel cup S, at this time, the overall appearance of the metal wick 1 is slightly inverted U-shaped, a lighting end 24 for lighting flame is formed at the original middle bent part of the capillary structure 20, and two ends which are originally longitudinally different are bent and then located at one side of the opposite lighting end 24, so as to form two absorption ends 25 capable of absorbing fuel. Therefore, the metal wick 1 of the present embodiment has higher versatility, and can be used for fuel cups S of different heights without cutting.

capillary structures

20, 20a is two, and the structure is substantially the same as that described in the previous embodiment. The difference lies in that: the two

capillary structures

20, 20a are coaxially sleeved with each other along a central axis C of the hollow chamber 10. Since the plurality of

capillary structures

20, 20a are sleeved with each other, the metal wick 1a provided by the present embodiment is not easy to bend, but is easy to maintain the bent shape.
