Benefits of technology
"The present invention provides a disposable lighter with a safety ignition unit, which is designed to improve safety features and prevent accidents caused by ignition. The lighter has a reasonably-structured design, low cost, and effectiveness in avoiding dangers caused by ignition of the lighter by children or errors in operation. The lighter includes a disposable lighter with a safety ignition unit, which has smooth, easily-rotating cinctures that make it difficult for a child's thumb or finger to slide off and accidentally ignite the lighter. The lighter is designed to be more convenient for adults and safer than existing technologies."
Problems solved by technology
Presently, most lighters available in the market, especially disposable lighters, can be easily ignited by young children and thus cause hidden dangers in property loss and personal injury.
However, a simple lighter such as this cannot effectively avoid various risks caused by ignition of the lighter when a child plays with the lighter, as sparks may be fairly easily generated when the combined igniting wheel and the cincture unit is rotated accidentally.
As it is known that the disposable lighter is common and relatively cheap, it is impossible to incorporate expensive and complex safety devices which greatly increase the cost of the lighter.
Such expensive safety devices in a disposable lighter simply would not be tolerated by the economics of the marketplace.
1. Goal: Make the operation of ordinary lighters more difficult in restricting the use of such lighters by young children. It is for this purpose that U.S. Pat. Nos. 5,002,482 and 7,004,750 B2 disclosed a child-resistant device, incorporated with a relief mechanism to block the gas fuel and to prevent ignition of the lighter by pressing the safety ring downward.
However, the present inventor notes that the presence of the driving cavity makes it difficult to ensure the most proper engagement between the driving caps and the gears of driving wheels, thus causing the ignition operation somewhat difficult.
However, the present inventor notes that, since the fingers of the adults are greatly inconsistent in length, the design and manufacture of the safety gap and the “uncovered portion” of the drive wheels are of great difficulty.
In addition, even if a safety gap is designed, it does not necessarily suit each adult user.
However, if the controller is pushed inwardly and upwardly, then the through hole of the plate of the controller is engaged with the protrusion beneath the lever press plate, such that the controller cannot block the gas.
This improvement measure has indeed improved the safety of the igniter, but it also leads to higher design and production cost.
Whichever measure is used, there will be some drawbacks, such as increase in cost due to increase of design works, assembly and materials, higher selling price or lower profit; therefore, these measures are impractical for widespread use.

Embodiment Construction
[0032]Referring to the Figures, there are shown some, but not the only embodiments, of the invented igniting wheel set with safety device, and the invented lighter comprising said igniting wheel set.
[0033]Referring to FIGS. 1, 4-6, safe lighters 100, 100′ with safety ignition unit includes a body B and a head H. The body comprises a fuel tank 10 encasing lighter fuel, a wick housing 4, and a wick 5. On or underneath the head H are installed valve / nozzle 11, a adjustment ring 2, a wind mask 1, a lever press plate 6, outer head 9, a igniting wheel set 3 with safety device, spring 8, and a flint 7, a conduction core 5. Parts of the lighter valve / nozzle system are shown in FIG. 5, for example, nozzle body 112, nozzle O-ring 112, nozzle spring 114, nozzle member 115, T-valve 116, nozzle lid 117, body O-ring 118, nozzle washer 119, and sponge filter 120.
[0034]Referring to FIGS. 2, 3, 6 and 7, the igniting wheel set 3, 3′ with safety ignition device is shown to best advantage. The igniting...

A disposable lighter with safety ignition unit is comprised of a body and a head, wherein a nozzle, a ring, a wind mask, a lever press plate, a spring, a flint, a bracket and an igniting wheel set with safety ignition unit are arranged on said head. The igniting wheel set with safety ignition unit includes two central axles, two cinctures and an ignition wheel which is used to make friction with said flint so as to generate sparks, said two cinctures are located on each end of said igniting wheel, the inner diameter(s) of said cincture is slightly larger than the outer diameter of the portions of the igniting wheel set which they encircle, so as to form the rotation of the cinctures as “sliding wheels.” The two central axles are supported on the bracket of the outer head and act as common rotational axle of said cinctures and igniting wheel. Characterized by its reasonably structured design and low cost, the present disposable lighter can effectively avoid dangers caused by ignition of lighter by a child or errors in operation.
Description
[0001]This application claims priority of, and is a continuation-in-part of, PCT International Application, PCT / CN2006 / 00134, filed Jan. 24, 2006, which application is incorporated herein by this reference.FIELD OF INVENTION[0002]The present invention relates to a disposable lighter with a safety ignition unit that makes the operation of an unintended user more difficult, more particularly an ignition unit preventing children from igniting the disposable lighter unnecessarily.BACKGROUND[0003]Presently, most lighters available in the market, especially disposable lighters, can be easily ignited by young children and thus cause hidden dangers in property loss and personal injury. More and more countries, especially Western countries, have attached great importance to the protection of children and imposed strict measures on safety requirements for lighters. Nowadays, both the U.S. government and U.S. Consumer Product Safety Commission demand a safety device in every cigarette lighter,...
