Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a lighter, and more particularly to a piezoelectric lighter with a pivot nozzle head, wherein the nozzle head is adapted to turn with respect to a lighter body so as to selectively adjust an ignition angle of the nozzle head.

2. Description of Related Arts

A lighter is a common tool that replaces matches for igniting cigarettes and cigars. Generally, a conventional lighter, such as a piezoelectric lighter, comprises a lighter casing having a liquefied fuel storage, a gas nozzle extended to a ceiling of the lighter casing and communicating with the liquefied fuel storage for controlling a flow of gas, a piezoelectric unit disposed in the lighter casing for generating sparks when the piezoelectric unit is depressed, and a pusher button slidably mounted on the lighter casing and arranged when the pusher button is depressed downwardly, the piezoelectric unit is depressed while the gas is released from the liquefied fuel storage to the gas nozzle and is ignited by the sparks.

However, such piezoelectric lighter has a major drawback that such piezoelectric lighter can provide a single ignition angle. Since the gas nozzle is fixed to the lighter casing in an upright manner, the gas can only upwardly ejected from the gas nozzle to form the flame when the lighter is ignited. For example, when the user wants to lighten up a candle, he or she may merely put the lighter at a slanted position that the gas nozzle is pointing at the top of the wick such that the flame can directly lighten the wick. Since the gas is upwardly ejected from the gas nozzle, the lighter cannot effectively lighten the candle when the lighter is in such slanted position.

In order to solve the above problem, the lighter manufacturer can make the piezoelectric lighter that the gas nozzle is inclinedly supported at the lighter casing such that the gas nozzle is adapted to directly pointing at the wick of the candle while the lighter casing is at an upright manner. However, such lighter is not practical use for lightening a cigarette. In addition, most users would like to use a utility lighter having an elongated gas nozzle tube to lighten up the candle. However, the utility lighter is bulky that the user is unable to carry the utility lighter in his or her pocket.

SUMMARY OF THE PRESENT INVENTION

A main object of the present invention is to provide a piezoelectric lighter, which comprises a nozzle head adapted to turn with respect to a lighter body so as to selectively adjust an ignition angle of the nozzle head.

Another object of the present invention is to provide a piezoelectric lighter, wherein the nozzle head is pivotally mounted on the lighter body such that the user is able to pivotally turn the nozzle head to select the gas ejecting either at an upright manner or at an inclined manner from the nozzle head so as to enhance the practical use of the piezoelectric lighter.

Another object of the present invention is to provide a piezoelectric lighter, wherein the nozzle head comprises a nozzle seat pivotally mounted to the lighter body and a gas emitting nozzle mounted on the nozzle seat in a stationary manner such that when the nozzle seat is turned with respect to the lighter body, the gas emitting nozzle is correspondingly supported by the nozzle seat so as to ensure the gas ejecting at the gas emitting nozzle.

Another object of the present invention is to provide a piezoelectric lighter, which does not require to alter the original structural design of the lighter so as to minimize the manufacturing cost of the lighter incorporating with the nozzle head.

Another object of the present invention is to provide a piezoelectric lighter, wherein no expensive or complicated mechanism is required to employ in the piezoelectric lighter, so that the present invention successfully provides an economic and efficient solution not only for allowing the nozzle head to be turned to adjust the ignition angle of the lighter but also for facilitating the practical use of the lighter.

Accordingly, in order to accomplish the above objects, the present invention provides a piezoelectric lighter, comprising:

a lighter body having a liquefied gas storage and a gas tube communicatively extending therefrom;

As shown in FIG. 2, the pusher button 30, which is slidably mounted on the sidewall of the lighter body 10 along the pusher slot 13, has a depressing arm 31 extended into the lighter body 10 to rest on top of the movable operating part 21 of the piezoelectric unit 20 and arranged in such a manner that when the pusher button 30 is depressed downwardly, the movable operating part 21 of the piezoelectric unit 20 and the depressible end 152 of the gas lever 15 are respectively depressed at the same time to generate the sparks and to release the gas so as to ignite the piezoelectric lighter.

When the nozzle head 40 is pivotally turned to adjust the orientation of the gas emitting nozzle 42 with respect to the lighter body 10, the gas is ejected correspondingly to adjust the igniting angle of the piezoelectric lighter. It is worth to mention that when the nozzle head 40 is pivotally turned, the nozzle seat 41 retains the gas tube 12 and the ignition tip 22 of the piezoelectric unit 20 in position so as to ensure the gas ejecting at the gas emitting nozzle 42 and being ignited properly.
