Metallic Wick Assembly

Abstract

A metallic wick assembly includes at least one mesh member and a sleeve member. The at least one mesh member includes a first length defined between first and second ends thereof. The sleeve member is mounted around the mesh member and includes a second length defined between two longitudinal opposite ends thereof. The second length is less than the first length. A third length is defined between a distal end of the sleeve member and the first end of the mesh member. The sleeve member is slidable with respect to the mesh member to adjust the third length for controlling the flame scale.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a wick assembly and, more particularly, to a wick assembly made of metal and provided for being mounted to a lamp device for precisely control the flame combustion scale.[0003]2. Description of the Related Art[0004]A conventional lamp device includes a fuel cup storing fuel, and a wick connecting into fuel stored in the fuel cup. Moreover, the wick is normally made out of braided cotton and works by capillary action. Fuel is drawn up through the wick to reach the flame produced on the disk. The above lamp device is actively used for various purposes, such as lighting, decorating, or increasing atmosphere. For example, an oil lamp is used in religion, or an alcohol lamp is used in medical or chemical laboratories.[0005]The conventional cotton wick must be cut to a predetermined length adapted for being mounted to the lamp device. However, after trimming, the cotton wick is easily loosened...

AI Technical Summary

Benefits of technology

The metallic wick assembly described in this patent has two important advantages. First, the sleeve member can slide back and forth to adjust the flame scale. Second, the assembly is made of metal, which lowers manufacturing costs and makes it more affordable. The mesh member is made of a common metal wire mesh, and the sleeve member is made of a common metal tube. These features make the metallic wick assembly a popular choice among consumers.

Problems solved by technology

However, after trimming, the cotton wick is easily loosened at its terminal end.

Trimming the cotton wick results in the wick eventually unconnected with fuel, so that users can only replenish fuel or replace a new wick.

It is inconvenient and wasteful.

However, cotton wicks with low stiffness and low fire-resistance cannot be adjusted easily to maintain proper fuel wicking and flame scale, especially for high viscosity or high flash point fuels results in producing carbon deposits and difficult to ignite.

If the fuel drawn is slower than it burns, wick will be carbonized and burnt out.

If the fuel drawn is more than it burns, usually occurring on burning high flash point fuel, will cause slow evaporation of the fuel and produce soot due to incomplete combustion.

Incomplete combustion not only produces soot but also toxic fumes.

The fiberglass layer is able to draw fuel by capillary action, hard to burn down, and not easily being loosened at its terminal end.

However, the fiberglass layer does not draw fuel effectively to cause the flame extinguished easily and the flame scale difficult to be controlled.

Therefore, the wick disclosed by said patents both include fiberglass filaments, but the fiberglass is expansive, difficult processing.

Momentously, the wick is a large quantity of consumable items, but the fiberglass wick is expensive, and not environment-friendly.

Additionally, when the fiberglass wick is processed, inhaling the fiberglass can cause damage to human lungs and be harmful to manufacturing personnel.

Inhaling of fiberglass will jeopardize the health of workers during fiberglass-reinforced plastic processing.

The fiberglass fiber can also cause skin, eye and throat irritation to users.

At higher exposure levels, the fiberglass also has been associated with skin rashes and difficulty in breathing.

Thus, the user cannot adjust the flame height or scale easily.

At the same time, the user may also contact fuel in the wick and cause inconvenience or even danger.
