ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a flame adjusting device for a gas burning device and includes a wheel having a neck to which a ring is engaged. A valve extends through the ring and is securely connected to the wheel. The wheel can be rotated to rotate the valve while the neck is hold.
BACKGROUND OF THE INVENTION
A conventional lighter is shown in FIG.
1
and generally includes a valve connected to a top of a tank for receiving butane (for example) therein and the valve includes a disk
12
with a tube
120
extending from the disk
12
. A flame adjusting wheel
11
has a threaded inner periphery is mounted to a threaded outer periphery of the disk
12
. A gas lever
10
is connected to the tube
120
on the disk
12
so that when lifting the gas lever
10
, the valve is actuated and the gas in the tank releases to be burned. A U-shaped member
13
is mounted to the top of the tank and a notch
130
is defined in a lower edge of the U-shaped member
13
. A protrusion
111
extends from the adjusting wheel
11
and is accessed from notch
130
so that when shifting the protrusion
111
, the disk
12
is rotated to adjust the volume of the gas releasing from the valve. The protrusion
111
can only be shifted within the notch
130
so that if the user wants to adjust the flame to an extreme condition, he/she has to remove the adjusting wheel
11
from the disk
12
and then rotate the disk to change the basic status of the disk
12
so as to have a larger or smaller gas volume that is normally released. Nevertheless, this is not an expected way for the users to adjust the gas volume and could damage the lighter.
The present invention intends to provide a flame adjusting device that allows the user to adjust the status of the valve without disassembling the lighter.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a flame adjusting device for a gas burning device which has a valve connected to a gas tank and having a disk which controls a volume of gas released via the valve. A tube extends from the disk and a gas lever is connected to the tube. A striker member is located beside the disk. The flame adjusting device comprises a flame adjusting wheel which has a hole for securely engaging the disk therein. A neck extends from a periphery of the hole and a ring is mounted to the neck. A protrusion extends form the ring so that a user may shift the protrusion to adjust the disk.
The primary object of the present invention is to provide a flame adjusting device for a gas burning device wherein the original status of the disk of the valve of the burning device can be adjusted without disassembling the burning device.
