ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to stoves and more particularly to a battery operated ignition device for stove with improved characteristics.
BACKGROUND OF THE INVENTION
A conventional ignition device for stove
1
is shown in
FIG. 1
comprising an ignition switch
11
provided on the housing of stove
1
, a high voltage generator
13
within stove
1
being electrically coupled to ignition switch
11
through a conductive line, at least one second conductive line
15
(one is shown) extended from high voltage generator
13
and having an arc tip
151
near stove head
12
of stove
1
, a battery
16
in high voltage generator
13
, and a high voltage coil circuit
17
in high voltage generator
13
. An electrical connection is established between battery
16
and high voltage coil circuit
17
when ignition switch
11
is pressed. Hence, an arc is generated in arc tip
151
of second conductive line
15
by the enabled high voltage coil circuit
17
for igniting gas flowed from stove head
12
. However, the previous design suffered from a disadvantage. For example, when battery
16
is used up has to first detach housing of stove
1
and then detach housing of high voltage generator
13
prior to removing battery
16
for replacement. This is inconvenient. To the worse, it may be difficult to reassemble the stove
1
if one or more components (such as screw) are lost during above disassembly.
SUMMARY OF THE INVENTION
It is thus an object of the present invention to provide an ignition device for stove comprising a battery container projected from a housing of the stove and having a battery therein; a releasable ignition switch projected from an outer end of the battery container being capable of detaching the ignition switch for removing the battery from the battery container for replacement when the battery is used up; a high voltage generator within the stove being electrically coupled to the battery container through a first conductive line; and at least one second conductive line extended from the high voltage generator and having an arc tip proximal to a stove head of the stove; whereby an electrical connection is established between the high voltage generator and the battery when the ignition switch is pressed for generating an arc in the arc tip by the high voltage generator for igniting gas flowed from the stove head.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
