Safety lighter

Abstract

A safety lighter includes a gas tank, a wheel racket, a file wheel assembly, and a metal cap. A wheel racket being provided at the top of the gas tank further includes two file-wheel seats having a slot extended up therefrom and a multiplicity of match-up seats. The file wheel assembly made by pressing together a file wheel with relatively smaller shaft diameter and two side wheels having external teeth at the circumference edge and with shaft diameter greater that that of the file wheel has its salient shaft pivotally connected to the slot. The metal cap being slipped on the external portion of the wheel racket has an extension portion provided at a location adjacent to the file wheel assembly. Under normal condition, the extension portion of the metal cap meshes with the side wheels of the file wheel assembly and the external teeth of the file wheel having relatively small shaft diameter such that it is not easy to ignite the lighter by turning the file wheel assembly to rub against the flint since it is propped up by the extension portion. When it comes to ignite the lighter, one needs only to exert a small force to press down the file wheel assembly and the slot will guide the salient shaft of the file wheel assembly to slide downward. After pressing down, the file wheel assembly will separate the prop-up engaging of the extension portion of the metal cap and turn the file wheel assembly to rub against the flint to generate flame to achieve the ignition action. Therefore, the lighter is capable of avoiding the children playing with the lighter to cause hazard.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to an improvement of safety lighter, and more particularly, to a safety lighter having safety protecting structure.[0003]2. Description of the Prior Art[0004]The simple-type lighter provides consumers with conveniency and low cost, and claims to be a great breakthrough in the contemporary era ever since the first use of fire in human history. However, the lighter brings forth concerns on safety consideration. FIG. 1 is an exploded view of a common simple-type lighter structure of the prior art. As shown in FIG. 1, the structure of an early lighter structure includes a gas tank (100), a wheel racket (200), a file wheel (300), and a metal cap (400). The gas tank (200) being a hollow chamber for filling liquid gas includes a nozzle (1001) having a neck portion (1002) provided at a closed portion secured thereon. The wheel racket (200), having two file wheel seats (2001) extended therefrom with a small...

Benefits of technology

[0010]In light of the above-mentioned demerits of the prior art, the invention provides a safety lighter that aims to ameliorate at least some of the demerits of the prior art or to provide a useful alternative.

[0011]The primary objective of the invention is to provide a safety lighter making use of the two file-wheel-seat of the wheel racket having a slot to pivotally connected to a file wheel such that the extension portion of the metal cap meshes with the side wheels, which have external teeth at their circumference, of the file wheel assembly for increasing the interference of the turning of the file wheel assembly, thereby, it is not easy to ignite the lighter by turning the file wheel assembly to rub against the flint, thus it is capable of achieving high safety efficacy.

[0012]The secondary objective of the invention is to provide a safety lighter such a portion of the waste metal is retained for using for the extension portion and the salient pieces. Therefore, the invention is capable of increasing the efficacy of saving material without increasing any material cost nor any mold or cutting cost in the overall working process.

[0013]The further objective of the invention is to provide a safety lighter where the metal cap has a second match-up portions that is capable of positively make the engagement of the metal cap and the wheel racket even more secure without worrying about the dislocation, deformation or coming off due to impact or dropping from a high position so as to assure that the metal cap is not apt to come off, thereby, increase the efficacy of the overall safety protection. Moreover, the above-mentioned guided surface (241), which is appeared in arcuate and slant face, provides a guidance to facilitate the slip-on engagement of the metal cap (4), thereby again increase the efficacy of the overall safety protection

[0014]In order to achieve the above-mentioned objectives, a safety lighter is provided. The lighter includes a gas tank, a wheel racket, a file wheel assembly, and a metal cap. A wheel racket being provided at the top of the gas tank further includes two file-wheel seats having a slot extended up therefrom and a multiplicity of match-up seats. The file wheel assembly made by pressing together a file wheel with relatively smaller shaft diameter and two side wheels having external teeth at the circumference edge and with shaft diameter greater that that of the file wheel has its salient shaft pivotally connected to the slot. The metal cap being slipped on the external portion of the wheel racket has an extension portion provided at a location adjacent to the file wheel assembly. Under normal condition, the extension portion of the metal cap meshes with the side wheels of the file wheel assembly and the external teeth of the file wheel having relatively small shaft diameter such that it is not easy to ignite the lighter by turning the file wheel assembly to rub against the flint since it is propped up by the extension portion. When it comes to ignite the lighter, one needs only to exert a small force to press down the file wheel assembly and the slot will guide the salient shaft of the file wheel assembly to slide downward. After pressing down, the file wheel assembly will separate the prop-up engaging of the extension portion of the metal cap and turn the file wheel assembly to rub against the flint to generate flame to achieve the ignition action. Therefore, the lighter is capable of avoiding the children playing with the lighter to cause hazard

Problems solved by technology

However, the lighter brings forth concerns on safety consideration. FIG. 1 is an exploded view of a common simple-type lighter structure of the prior art.

However, as the lighter is very easy to ignite, children without crisis consciousness might often cause hazard by playing with it.

Although this kind of structure can protect the children from easily playing with the lighter, the demerits of the structure are that the elements are complicated and the cost is high.

In accordance with the above-mentioned structures of the safety lighters, one can see that there are some disadvantages: 1. Some structures are inconvenient in operation causing not easy in igniting; 2. Some structures are complicated in design making the cost become too high; 3. Some structures are inconvenient to use by “sense of touch” that might cause the car driver divert his / or her attention on driving when he / or she intend to use the lighter.
