Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a burner head for a gas
stove.
[0003] 2. Description of the Related Art
[0004] A burner head of a conventional gas stove used by people at
home comprises a base with an open upper side, a gas transportation
station connected with a gas channel provided at the central
location of the base, an annular cover covering the base, wherein a
circle of small holes and a circle of big holes are provided at the
outer surrounding of the annular cover and a circle of small holes
and a circle of big holes are provided at the inner surrounding of
the annular cover and a gas exit of the gas transportation station
is located on the inner surrounding of the annular cover. The fire
is burned beginning from the small holes while burning, and then
the fire is burned from the big holes via the small holes to form
four annular-shaped even-burning fires. This kind of burner head
can provide four annular-shaped even-burning fires. However, gas is
transported via the holes, and it may result in the fire jumps away
from the burner head due to excessive adjustment of air mixed with
the gas. As a consequence, the burning can not be kept steady. In
addition, the burning maybe incomplete due to insufficient amount
of the mixed air, and it even may cause excessive carbon monoxide
to increase the risk of poisoning the user. The water from the
bottom of the pot is usually dropped onto the burner head, and
resulting in burning can not happen in some fire holes. The safety
also needs to be concerned for the conventional gas stoves.
SUMMARY OF THE INVENTION
[0005] One objective of the present invention is to provide a
burner head for a gas stove, which can provide even-burning fire
flames and is more safety.
[0006] For achieving the above objective, the present invention
provides a burner head for a gas stove comprising a base and an
annular cover, which is characterized in that small holes through
inner and outer surroundings of said annular cover are disposed at
a lower portion of said annular cover and gas-exiting grooves
through the inner and outer surroundings of said annular cover are
disposed at an upper portion of said annular cover.
[0007] As mentioned in the present invention, the two adjacent
gas-exiting grooves are arranged as a predetermined angle contained
therebetween.
[0008] As mentioned in the present invention, the predetermined
angle is 15 degrees.
[0009] As above-mentioned in the present invention, a longitudinal
dimension of the gas-exiting groove is tilted to a vertical
direction of the annular cover.
[0010] As above-mentioned in the present invention, an upper
surface of the gas-exiting groove is formed of a slope surface.
[0011] The present invention has advantages as follows: 1. The
gas-exiting grooves of the present invention are disposed in tilt
so that the burning fire becomes rotating flames and the
even-burning effect can be attained. 2. The rotating flames formed
from the tilt gas-exiting grooves of the present invention 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. 3. The gas-exiting
grooves of the present invention provide more stable burning than
the conventional holes structure. The influence of taken-in air
flow is small, and it overcomes the problem that the fire jumps
away from the burner head due to the too high air flow rate, and
hence the safety of the gas stove is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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.
