Description:

BACKGROUND OF THE PRESENT INVENTION

[0001] 1. Field of Invention

[0002] The present invention relates to a lighter nozzle system for a lighter, and more particularly to a lighter nozzle system for producing a stylish torch via a single fuel supplying source so as to enhance the aesthetic visible effect of the lighter when ignition.

[0003] 2. Description of Related Arts

[0004] A lighter is a common tool that replaces matches for igniting cigarettes and cigars. Generally, there are two types of lighter, namely the regular lighter that produces flat flame and the torch lighter that produces torch.

[0005] There are various types of regular lighter, including the disposable lighter incorporated with a flint type ignition system and the piezoelectric lighter incorporated with a piezoelectric type ignition system. Such regular lighter is capable of generating a flat flame which is merely a single tongue of flame. Due to the soft and weak nature of the flat flame, most of such flat flame lighters are good at igniting cigarettes but find difficulty when igniting a cigar.

[0006] Since the cigar has a bigger diameter and the cigar tobacco is dryer and harder the torch lighter that can produce a stronger and hotter torch is generally used to ignite the cigars. As shown in FIG. 1, the torch nozzle system for such torch lighter comprises a nozzle body having a fuel inlet communicatively connected to a liquefied fuel storage and an emitting opening, and torch head, which is provided at the emitting opening of the nozzle body, having an elongated nozzle duct arranged in such a manner that when the ignition unit produces sparks towards the torch head, the fuel released from the emitting opening to outside through the nozzle duct is ignited to form a strong and stable torch. Although such torch is stronger and hotter than the flat flame, its ignition area is relatively small and limited.

[0007] In order to increase the ignition area of the torch lighter, how to produce two or more torches simultaneously will be an effective solution. Since it is too costly and not practical to provide two or more torch nozzles in the limited interior space of the housing of the torch lighter, it is not available in market.

[0008] In addition, the torch nozzle system for such torch lighter can only produce the long and tall soaring torch. No such torch lighter in market is capable of producing a stylish torch to enhance the aesthetic visible effect for the torch lighter when ignition.

SUMMARY OF THE PRESENT INVENTION

[0009] A main object of the present invention is to provide a lighter nozzle system for producing a stylish torch via a single fuel supplying source so as to enhance the aesthetic visible effect of the lighter when ignition.

[0010] Another object of the present invention is to provide a lighter nozzle system for producing a stylish torch, wherein the lighter nozzle system comprises a nozzle head disposed in the emitting opening of the nozzle body to diverge the fuel releasing therefrom so as to virtually produce the stylish torch. Therefore, by varying the shape of the nozzle head, different styles of the stylish torch can be produced.

[0011] Another object of the present invention is to provide a lighter nozzle system for producing a stylish torch, wherein the lighter nozzle system is capable of being installed into any kind of torch lighter to produce the stylish torch without altering the original structural design of the torch lighter so as to minimize the manufacturing cost of the torch lighter incorporating with the lighter nozzle system of the present invention.

[0012] Another object of the present invention is to provide a lighter nozzle system for producing a stylish torch, wherein the stylish torch produced by the lighter nozzle system have the same heat intensity in comparison with a torch produced by the conventional nozzle system. In other words, the structural configuration of the lighter nozzle system will not weaken the intensity of the torch.

[0013] Another object of the present invention is to provide a lighter nozzle system for producing a stylish torch, wherein since the releasing fuel is diverged at the nozzle head, the stylish torch can substantially increase its ignition area thereof. In other words, the stylish torch is more useful than the conventional torch especially good at igniting cigars.

[0014] Accordingly, in order to accomplish the above objects, the present invention provides a lighter nozzle system for a lighter having a liquefied fuel storage, comprising:

[0015] a diffusion body having a receiving opening adapted for communicating with the liquefied fuel storage, an emitting opening, at least an air inlet provided thereon, wherein the air inlet is positioned adjacent to the receiving opening to define an elongated mixing chamber axially extended between the air inlet to the emitting opening, wherein a flow of air is capable of inletting into the mixing chamber through the air inlet to mix with a fuel releasing through the receiving opening to form a mixture gas at the emitting opening of the diffusion body; and

[0016] a nozzle assembly comprising a nozzle head provided at the emitting opening of the diffusion body and a torch diversion arrangement provided at the nozzle head for radially diverging the mixture gas to produce a stylish torch when the mixture gas is ejected and ignited at the nozzle head.

[0017] These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.

[0028] The lighter nozzle system comprises a diffusion body 10 and a nozzle assembly 20. The diffusion body 10 has a receiving opening 11 adapted for communicating with the liquefied fuel storage, an emitting opening 12, at least an air inlet 13 provided thereon, wherein the air inlet 13 is positioned adjacent to the receiving opening 11 to define an elongated mixing chamber 14 axially extended between the air inlet 13 to the emitting opening 12, wherein a flow of air is capable of inletting into the mixing chamber 14 through the air inlet 13 to mix with the fuel releasing through the receiving opening 11 to form a mixture gas at the emitting opening 12 of the diffusion body 10.

[0029] The nozzle assembly 20 comprises a nozzle head 21 provided at the emitting opening 12 of the diffusion body 10 and a torch diversion arrangement 22 provided at the nozzle head 22 for radially diverging the mixture gas to produce a stylish torch when the mixture gas is ejected and ignited at the nozzle head 21.

[0030] As shown in FIGS. 2 and 3A, the diffusion body 10 is a tubular throat conduit having a root end 101 forming the receiving opening 11 and an emitting end 102 forming the emitting opening 12 wherein the emitting end 102 of the diffusion body 10 is formed to have a surrounding wall 15 coaxially surrounding the emitting opening 12 and defining a gas chamber 150 positioned above the emitting opening 12, wherein the nozzle head 21 of the nozzle assembly 20 is disposed at the gas chamber 150.

[0031] The air inlet 13 is transversely formed on the root end 101 of the diffusion body 10 and has a diameter slightly larger than a diameter of the mixing chamber 14 so as to provide a suction force to absorb the air into the mixing chamber 14 in such a manner that the mixing chamber 14 has a predetermined length and size arranged for the air and the fuel being evenly mixed to form the mixture gas at the emitting opening 12 of the diffusion body 10.

[0032] Accordingly, the lighter nozzle assembly further comprises a fuel vaporizer 30 connected between the receiving opening 11 of the diffusion body 10 and the liquefied fuel storage of the lighter wherein the fuel vaporizer 30 has a micro nozzle pore 31 arranged for vaporizing the fuel released from the liquefied fuel storage into a strong, pressurized gaseous fuel towards the mixing chamber 14 of the diffusion body 100 through the micro nozzle pore 31 of the fuel vaporizer 30.

[0033] When the fuel released from the liquefied fuel storage of the lighter to the receiving opening 11 of the diffusion body 10, the fuel is vaporized to a high-pressure gaseous fuel jetting into the mixing chamber 14 wherein the jetting gaseous fuel and the air flowing through the mixing chamber 14 are mixed to form the mixture gas at the emitting opening 12 of the diffusion body 10.

[0034] As shown in FIG. 2, the nozzle head 21 has a base portion 211 disposed within the gas chamber 150 and a head portion 212 extended above the surrounding wall 15 of the diffusion body 10 wherein the nozzle head 21 further has an elongated nozzle duct 213 extended from the base portion 211 through the head portion 212 to communicate with the gas chamber 150 of the diffusion body 10 and a plurality of guiding teeth 214 radially and evenly extended from an outer circumferential surface of the base portion 211 of the nozzle head 21 to bias against an inner circumferential surface of the surrounding wall 15 of the diffusion body 10 so as to retain the nozzle head 21 at the emitting opening 12 of the diffusion body 10.

[0035] As shown in FIG. 3B, the torch diversion arrangement 22 has a plurality of diverging channels 221 evenly positioned around the nozzle head 10 to communicate with the gas chamber 150 wherein each of the diverging channels 221 is formed between the inner circumferential surface of the surrounding wall 15 and each outer circumferential surface of the guiding teeth 214 in such a manner that when the mixture gas is released to the gas chamber 150 through the emitting opening 12, the mixture gas is guided to radially diverge at the nozzle head 21 through the diverging channels 221.

[0036] As shown in FIG. 3, the nozzle duct 213 has a diameter smaller than a diameter of the emitting opening 12 of the diffusion body 10 in such a manner that a relative small portion of the mixture gas released at the emitting opening 12 is allowed to release to outside through the nozzle duct 213 while a main portion of the mixture gas is forced to eject through the diverging channels 221 in a radial manner with respect to the nozzle head 10. Therefore, once the ignition unit of the lighter produces the sparks towards the nozzle head 10, the mixture gas is ignited to form the stylish torch having a petal shaped, as shown in FIG. 4, so as to enhance the aesthetic visible effect of the lighter when ignition.

[0037] It is worth to mention that since the mixture gas is diverged via the torch diversion arrangement 22 to radially eject from the nozzle head 21 to produce the stylish torch, the ignition area of the stylish torch is substantially increased for enhancing ignition purpose of the lighter. Furthermore, the stylish torch produced by the lighter nozzle system have the same heat intensity in comparison with a torch produced by the conventional nozzle system because the same amount, of the fuel is released through the lighter nozzle system of the present invention.

[0038] FIG. 5 illustrates a first alternative mode of the nozzle assembly 20A of the lighter nozzle system wherein by altering the nozzle assembly 20A, the lighter nozzle system can produce different kinds of stylish torch without changing the structure of the diffusion body 10.

[0039] As shown in FIG. 5, the nozzle head 21A has a base portion 211A disposed with the gas chamber 150 and a head portion 212A extended above the surrounding wall 15 of the diffusion body 10 wherein the nozzle head 21 A further has an elongated nozzle duct 213A extended from the base portion 211A towards the head portion 212A to communicate with the gas chamber 150, a plurality of first nozzle grooves 214A transversely and evenly formed on the head portion 212A of the nozzle head 21A to communicate with the nozzle duct 213A, and a plurality of second nozzle grooves 215A transversely and evenly formed on the head portion 212A at a position above the first nozzle grooves 214A to communicate with the nozzle duct 213A, thereby, the mixture gas released at the gas chamber is allowed to radially eject from the nozzle head 21A through the first and second nozzle grooves 214A, 215A to outside through the nozzle duct 213A.

[0040] Accordingly, each of the first nozzle grooves 214A has a diameter slightly larger than a diameter of each of the second nozzle grooves 215A, thereby, a relative large portion of the mixture gas is released to outside through the first nozzle grooves 214A while a relative small portion of the mixture gas is released to outside through the second nozzle grooves 215A. In addition, each of the first nozzle grooves 214A and each of the second nozzle grooves 214A are perpendicularly extended from the nozzle duct 213A such that each of the first nozzle grooves 214A is parallel to each of the second nozzle grooves 215A.

[0041] The torch diversion arrangement 22A comprises a diverging guider 221A having a ring shaped coaxially mounted on the head portion 212A of the nozzle head 21 A at a position between the first nozzle grooves 214A and the second nozzle grooves 215A wherein the diverging guider 221A has an upper guiding surface 222A for radially diverging the mixture gas ejected from the second nozzle grooves 215A and a lower guiding surface 223A for radially diverging the mixture gas ejected from the first nozzle grooves 214A.

[0042] As shown in FIG. 5, the diverging guider 221A is constructed to have a concave shape to form an upper concavity surface as the upper guiding surface 222A for guiding the mixture gas ejected from the second nozzle grooves 215A while the diverging guider 221A has a flat bottom surface as the lower guiding surface 223A for guiding the mixture gas ejected from the first nozzle grooves 214A. In other words, the mixture gas ejected from the first nozzle grooves 214A is radially diverged with respect to the nozzle head 21A via the lower guiding surface 222A of the diverging guider 221A while the mixture gas ejected from the second grooves 214A is radially diverged via the upper guiding surface 221A to form the stylish torch having a petal shaped.

[0043] FIG. 6 illustrates a second alternative mode of the nozzle assembly 20B of the lighter nozzle system for the lighter to produce the stylish torch.

[0044] As shown in FIG. 6, the nozzle head 21B has a base portion 211B disposed with the gas chamber 150 and a head portion 212B extended above the surrounding wall 15 of the diffusion body 10 wherein the nozzle head 21B further has an elongated nozzle duct 213B extended from the base portion 211B through the head portion 212B to communicate with the gas chamber 150, a plurality of first nozzle grooves 214B transversely and evenly formed on the head portion 212B of the nozzle head 21B to communicate with the nozzle duct 213B, and a plurality of second nozzle grooves 215B transversely and evenly formed on the head portion 212B at a position above the first nozzle grooves 214B to communicate with the nozzle duct 213B, thereby, the mixture gas released at the gas chamber is allowed to radially eject from the nozzle head 21B through the nozzle duct 213B, the first and second nozzle grooves 214B, 215B to outside.

[0045] Accordingly, each of the second nozzle grooves 215B is inclinedly and upwardly extended from the nozzle duct 213B, thereby, the mixture gas released from the second nozzle grooves 215B is radially, inclinedly and upwardly ejected with respect to the nozzle head 21B. In addition, an outlet end of the nozzle duct 213B has a diameter larger than an inlet end of the nozzle duct 213B in such a manner that when the mixture gas is released from the gas chamber 150 to the nozzle duct 213B at the inlet end thereof, the mixture gas is forced to be diverged to eject from the nozzle head 21B through the outlet end of the nozzle duct 213B, and the first and second nozzle grooves 214B, 215B.

[0046] The torch diversion arrangement 22B comprises a diverging guider 221B having a ring shaped coaxially and integrally extended from an outer circumferential surface of the head portion 212B of the nozzle head 21B at a position between the first nozzle grooves 214B and the second nozzle grooves 215B for radially diverging the mixture gas ejected from the first nozzle grooves 214B.

[0047] FIG. 7 illustrates a third alternative mode of the nozzle assembly 20C of the lighter nozzle system, wherein the nozzle assembly 20C has the exact same structural design in accordance with the nozzle assembly 20 of the preferred embodiment, except the nozzle duct 213C of the nozzle assembly 20C has a diameter larger than a diameter of the nozzle duct 213 of the nozzle assembly 20.

[0048] Accordingly, the third alternative mode of the nozzle assembly 20C mainly illustrates that the stylish torch can be alternatively produced by adjusting the dimension of the nozzle duct 213C. Likewise, the dimension of the guiding teeth 214 of the nozzle head 21 can also be altered to form different kinds of stylish torch. As shown in FIG. 7, when the diameter of the nozzle duct 213C is enlarged, the stylish torch is formed to have a relatively higher peak since more mixture gas is ejected from the nozzle duct 213C to outside.

[0049] FIG. 8 illustrates a fourth alternative mode of the nozzle assembly 20D of the lighter nozzle system. The nozzle head 21D is integrally and upwardly extended from the diffusion body 10 wherein the nozzle head 21D has a nozzle duct 213D integrally upwardly extended from the emitting end 12 of the diffusion body 10 and a plurality of nozzle grooves 214D transversely and evenly formed on the nozzle head 21D to communicate with the nozzle duct 213D for guiding the mixture gas radially ejected from the nozzle head 21D from the nozzle grooves 214D through the nozzle duct 213D.

[0050] The torch diversion arrangement 22D comprises a diverging guider 221D having a ring shaped coaxially mounted on the head portion 212D of the nozzle head 21D at a position below the nozzle grooves 214D wherein the diverging guider 221D has an upper guiding surface 222D for radially diverging the mixture gas ejected from the nozzle grooves 214D. As shown in FIG. 8, the diverging guider 221D is constructed to have a concave shape to form an upper concavity surface as the upper guiding surface 222D for guiding the mixture gas ejected from the nozzle grooves 214D.

[0051] In the view of above, the lighter nozzle system for the lighter is capable of producing different stylish torches, such as pedal shape or flower shape, by changing the nozzle assemblies 20, 20A, 20B, 20C, 20D, without altering the diffusion body 10 to enhance the aesthetic visible effect of the lighter when ignition. In addition, the lighter does not required to change its original structure in order to incorporate with the lighter nozzle system of the present invention so as to minimize the manufacturing cost of the lighter.
