ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a gas volume control device for a gas burner and includes a bolt rotatably received in the casing of the burner and controlling communication between a passage, an inlet and an outlet so that the volume of the gas entering the outlet can be micro-adjusted.
BACKGROUND OF THE INVENTION
A conventional burner is shown in FIG.
1
and generally includes a casing
11
with a chamber
100
and an inlet tube
10
is connected to the casing
11
and communicates with the chamber
100
. An outlet tube
101
is connected to the casing
11
and communicates with the chamber
100
so that gas may enter the chamber
100
via the inlet tube
10
and come out from the outlet tube
101
to be burned. A valve
13
is received in the chamber
100
and biased by a spring
130
, a passage
131
is defined through the valve
13
so as to allow the gas to flow. An adjusting screw
14
is threadedly engaged with the inner threads
121
in the path of the control shaft
12
. The adjusting screw
14
can be rotated by a screw driver and extended into the valve
13
so that the volume of the gas can be controlled. Nevertheless, the flame of the burner is difficult to be controlled because the volume of the gas can only be controlled by using the screw driver and this takes time and inconvenient.
FIG. 2
shows an improved conventional burner which includes a casing
20
having an inlet tube
22
, an outlet tube, a valve
21
biased by a spring
210
and received in the chamber in the casing
20
, and an ignition device
24
which can be operated by rotating a shaft
23
. Although the burner has an ignition device
24
which allows the user to easily ignite the gas, the volume of the gas is not able to be controlled.
The present invention intends to provide a gas volume control device for a burner wherein the control device is connected to a side of the casing and easily to be operated for the users.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a gas burner which includes a casing having a chamber and a valve is received in the chamber and biased by a spring. An operation shaft is rotatably inserted in the casing and operatively connected to an ignition device. An orifice is defined through a wall of the valve and communicates between the inlet tube and the chamber. An inlet tube and an outlet tube are respectively connected to the casing and communicate with the chamber.
A receiving recess is defined in the casing and located perpendicular to an axis of the inlet tube. An opening is defined through an outside of the casing so as to receive an adjusting screw therein. A first passage is defined in communication between the inlet tube and the receiving recess. A second passage is defined in communication with the receiving recess. A third passage is defined in communication between the first passage and the second passage.
The adjusting screw is extended in a position that is in communication with the first passage and the second passage so that the gas volume can be controlled by rotating the screw.
The primary object of the present invention is to provide a gas volume control device which is easily to be made in the conventional gas burner without too much change in structure.
