Burner head for a gas stove

Abstract

This invention provides a burner head for a gas stove that can provide even-burning fire flames and is more safety. The burner head for a gas stove comprises a base and an annular cover, which is characterized in that small holes through inner and outer surroundings of the annular cover are disposed at a lower portion of the annular cover and gas-exiting grooves through the inner and outer surroundings of the annular cover are disposed at an upper portion of the annular cover.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to describe the structure and characteristics of the present invention in detail, a preferred embodiment accompanying with drawings is explained in the following.

As FIG. 1 through FIG. 4 shows, the burner head 1 of the present invention includes a base 10 and an annular cover 20 in which a circle of small holes 21 through inner and outer surroundings of the annular cover 20 formed on the lower portion of the annular cover 20, and a plurality of gas-exiting grooves 22 through the inner and outer surroundings of the annular cover 20 disposed on the upper portion of the annular cover 20. The gas-exiting grooves 22 are not disposed in radial directions from the center of annular cover 20 but are disposed in a way that a predetermined angle a is contained between the adjacent gas-existing grooves 22. As such, the rotating flame can be formed to attain the even-burning effect, and it can sufficiently burn the oxygen in the air. It is not only that the gas is burned sufficiently to increase the utility efficiency of gas but also that amounts of carbon monoxide owing to insufficient burning is decreased, and improving the safety. The influence of taken-in air flow is small, and hence it makes the burning more stable. The best effect is generated at 15-degree angle. The connecting assembly of the base 10 and the annular cover 20 is similar to ordinary art, and they can be connected by screw or other connecting ways.

As FIG. 4 and FIG. 5 show, the longitudinal dimension of each of the gas-exiting grooves 22 is slightly tilted to the vertical direction, and the burning fire can be enhanced further to form the rotating flame effect by such configuration. The upper portion of each of the gas-exiting grooves 22 is not flat, but a slope surface is formed instead. It also can enhance the rotating flame effect.

While the invention has been described by way of examples and in terms of preferred embodiments, it is to be understood that those who are familiar with the subject art can carry out various modifications and similar arrangements and procedures described in the present invention and also achieve the effectiveness of the present invention. Hence, it is to be understood that the description of the present invention should be accorded with the broadest interpretation to those who are familiar with the subject art, and the invention is not limited thereto.
