Description

metal wick

technical field

The present invention relates to a lamp wick structure, in particular to a lamp wick structure woven from metal wires.

Background technique

In the existing lamp, a high-temperature resistant disc body is assembled above the fuel cup, and a rope-shaped cotton wick is passed through the disc body, so that the wick can hang into the fuel cup. The cotton wick can absorb the fuel in the fuel cup by means of capillary phenomenon, and ignite with flame at the top of the wick, so that the fuel can be burned. However, the cotton wick is woven into a rope-like shape with cotton threads, and the ends are easy to spread out when cut, and it is not easy to pass through the disc. In addition, the cotton wick is prone to carbonization at the top when burning fuel, which is not conducive to combustion.

In addition, if the cotton wick is used with a slightly higher viscosity fuel, the adsorption of the cotton wick will be relatively lower than that of the high viscosity fuel, and the flame is not easy to ignite, or it will go out soon after ignition, so the cotton wick is used in The fuel with slightly higher viscosity cannot achieve the effect of stable and continuous ignition, and the oil absorption effect is not good, and it is easy to generate a large amount of smoke and cause environmental pollution.

In addition, the core of the cotton wick is not dense enough, and it is easy to cause carbon deposition when burning, and the ignited flame is unstable. If there is too much carbon deposition, it will not be easy to ignite. If the fuel is overfilled, the carbon deposition of the cotton wick will cause abnormality. Burning and dangerous.

Therefore, like the patent case of Taiwan Patent Publication No. 493722 "Wick Structure Improvement" and the Taiwan Patent Publication No. 580106 "Wick Structure Improvement for Oil Lamp or Alcohol Lamp", the above two patent cases are improved by glass fiber. The shortcomings of cotton wicks, but there are still many shortcomings in this kind of glass fiber wicks, which need to be improved. First of all, from the perspective of manufacturing, the material cost of glass fiber is high, and the weaving process of glass fiber and cotton thread is complicated, resulting in a corresponding increase in the price of glass fiber wicks, and the wicks are a large number of consumables, so it is impossible to provide consumers with a Affordable prices. Furthermore, from the perspective of environmental protection, glass fiber has the potential to cause indirect or direct damage to the cardiopulmonary function, both for users and on-site manufacturers.

In fact, fiberglass wicks will also carbonize when burning fuel, but the carbonization rate is slower than that of cotton wicks. Therefore, it is also necessary to adjust the height or add fuel according to the carbonization of the wick. Furthermore, the glass fiber wick will sag after absorbing fuel by capillary phenomenon, and it is difficult for users to adjust the height of the flame, which is even more difficult to overcome when the glass fiber wick is used in ornamental lamps.
