BACKGROUND OF THE PRESENT INVENTION




1. Field of Invention




The present invention relates to a barbecue lighter, and more particularly to a barbecue lighter with a safety arrangement, the depression of the ignition trigger of the barbecue lighter normally cannot drive the depressible end of the gas lever downwardly for releasing gas. Therefore, no emitted gas is released and ignited so as to prevent the barbecue lighter from being ignited accidentally or by children.




2. Description of Related Arts




A barbecue lighter is commonly used at home such as pilot light for stoves or outdoor activities such as fireplaces or camping since the barbecue lighter can provide a father ignition distance comparing with an ordinary lighter.




A conventional barbecue lighter comprises a casing having a liquefied gas storage, a gas emitting nozzle extended from the liquefied gas storage for controlling a flow of gas, and an elongated nozzle tube extended from the casing for encircling the gas emitting nozzle. Due to the ignition operation of the barbecue lighter, the barbecue lighter usually incorporates with a piezoelectric unit in such a manner that when the trigger button is depressed downwardly to compress the piezoelectric unit and to release the gas from the liquefied gas at the same time, the sparks produced by the piezoelectric unit will ignite the emitted gas from the gas emitting nozzle.




For safety reasons, both the government and the consumers in United States demand a safety device employed in every lighter, including the barbecue lighter, to prevent unwanted ignition accidentally or by a child. One of the most common ways to incorporate the barbecue lighter with the safety device is to lock up the trigger button in a downwardly movable manner, so as to prevent the trigger button from being pressed downwardly to ignite the barbecue lighter. However, the operation of such safety device is unreliable.




Since the downward movement of the trigger button is locked up in the locking position, once the trigger button can be depressed downwardly, the barbecue lighter will be ignited. In other words, the child may easily to figure out how to unlock the barbecue lighter.




In order to stop the child from the usage of the barbecue lighter, a complicated safety device must be used, such as requiring a double-action operation to ignite the barbecue lighter. However, this adverse result affects the ease of operating the safety device and leads to different operational results depending on the users. Moreover, such safety device will highly increase the manufacturing cost of the barbecue lighter. Therefore, such safety device can be considered disadvantageous in practical use.




SUMMARY OF THE PRESENT INVENTION




A main object of the present invention is to provide a barbecue lighter with a safety arrangement, wherein the depression of the ignition trigger of the barbecue lighter normally cannot drive the depressible end of the gas lever downwardly for releasing gas. Therefore, no emitted gas is released and ignited so as to prevent the barbecue lighter from being ignited accidentally or by children.




Another object of the present invention is to provide a barbecue lighter with a safety arrangement, wherein in order to ignite the barbecue lighter, the user must require to move a pusher arm of the safety arrangement to a position that the bottom portion of the pusher arm is positioned right above the depressible end of the gas lever and then depress the ignition trigger. Therefore, no gas is released when only depressing the ignition trigger, so as to prevent the barbecue lighter from being ignited accidentally or by children.




Another object of the present invention is to provide a barbecue lighter with a safety arrangement, wherein the ignition of the barbecue lighter of the present invention requires a simple single-action operation by an adult's finger instead of the conventional double-action operation.

According to the preferred embodiment, the pusher arm


711


is downwardly extended into the trigger cavity


12


, wherein a bottom portion of the pusher arm


711


functions as a pusher head adapted to depress the depressible end


42


of the gas lever


40


for releasing gas at the ignition position. In the ignition position, the pusher arm


711


is moved to a position that the bottom portion thereof is positioned above the depressible end


42


of the gas lever


40


to depress the depressible end


42

711


is arranged to be driven by the operation button


712


to move from the normally safety position, as shown in

FIG. 2

, to the ignition position, as shown in FIG.


3


.




Accordingly, the operation slot


61


is formed on a top wall of the ignition trigger


60


wherein an upper portion of the pusher arm


711


is extended out of the trigger cavity


12


through the operation slot


61


to form the operation button


712


. As shown in

FIG. 2

711


is extended out of the trigger cavity


12


through the operation slot


61


to form the operation button


712


, wherein the upper portion of the pusher arm


711


is arranged to move a bottom portion thereof above the depressible end


42


of the gas lever


40


at the ignition position.




As shown in

FIG. 2

, in the safety position, the bottom portion of the pusher arm


711


is positioned away from the depressible end


42


of the gas lever


40


with a predetermined distance in such a manner that when the ignition trigger


60


is depressed downwardly to drive the pusher arm


711


downward, the position of the gas lever


40


is remained unchanged, so that no gas is released to the gas emitting nozzle


20


.




In the ignition position, as shown in

FIG. 3

, the pusher arm


711


is moved at a position that the bottom portion thereof is positioned above the depressible end


42


of the gas lever


40


in such a manner that when the ignition trigger


60


is depressed downwardly to drive the pusher arm


711


downward, the depressible end


42


of the gas lever


40


is depressed downwardly by the pusher arm


711


for releasing gas.




Therefore, in the safety position, even though the ignition trigger


60


is adapted to be pressed downwardly to compress the piezoelectric unit


50


, the barbecue lighter cannot be ignited since no gas is released. In other words, the safety arrangement


70


can prevent the barbecue lighter from being ignited accidentally or by children.




The resilient element


72


, according to the preferred embodiment, is a compression spring disposed in the trigger cavity


12


for applying an urging pressure against the pusher arm


711


so as to normally retain the pusher arm


711


at the safety position. As shown

FIG. 2

, the resilient element


72


is provided between the pusher arm


711


and an inner wall of the ignition trigger


60


. The resilient element


72

60


, wherein the first holder


73


and the second holder


74


are adapted to engage with two ends of the resilient element


72


respectively so as to securely hold the resilient element


72


between the pusher arm


711


and the inner wall of the ignition trigger


60


. Accordingly, the first and second holders


73


,


74


, each having a rod-like shape, are adapted to insert into the two ends of the resilient element


72


respectively.




In order to ignite the barbecue lighter, the user must intentionally push the operation button


712


frontwardly so as to move the pusher arm


711


to a position that the bottom portion thereof is positioned aligning above the depressible end


42


of the gas lever


40


, i.e. the ignition position of the barbecue lighter. At the same time, a downward force must be applied on the ignition trigger


60


to drive the pusher arm


711


downwardly so as to depress the depressible end


42


of the gas lever


40


for releasing gas. Therefore, the movable operating part


51


of the piezoelectric unit


50


is compressed to generate the sparks through the ignition tip


52


for igniting the emitted gas through the gas emitting nozzle


20


.




After the barbecue lighter is ignited, the user may release the depressing of the ignition trigger


60


in such a manner that the compressed piezoelectric unit


50


will rebound to its original form which pushes the ignition trigger


60


upwardly back to the original position. Furthermore, the compressed resilient element
