Abstract

The utility model relates to a safety lighter which uses a fire stone to strike fire. The utility model comprises a lighter body, a wind proof cover, an air valve device, a middle support frame, a spark generating device and safety devices, wherein the safety devices are arranged at two positions on the lighter. One safety device is arranged at both sides of a strike fire wheel and is composed of a rotating shaft fixedly connected with the inner part of a shaft hole of the strike fire wheel, and the maximum diameter of the rotating shaft is approximate to or the same as the diameter of the strike fire wheel; the other safety device is a damping element which is arranged at the lower part of the back of a lever and is used for preventing the lever from being pressed downwards. The lighter finishes striking fire for one time. The structures of the safety devices arranged at the two positions are simple, and the operation is convenient, safe and reliable.

Description

Safety lighter

It is the flint lighter of fuel with the liquefied gas that the utility model relates to a kind of, particularly is provided with the lighter of release mechanism.

For preventing that children from using lighter and the unconscious sparking of being grown up causes the generation of burn and fire incident, many countries all successively are defined in the lighter of selling its domestic market must be provided with safety device.In recent years, various safety lighters constantly are pushed to the market, if divide by the number of times of sparking action, these safety lighters roughly can be divided into two classes.One class is that the sparking action needs two actions just can finish, and the characteristics of this class lighter are that security is higher, but troublesome poeration; Another kind of lighter is that sparking does not have tangible two actions, and the characteristics of this class lighter are simple in structure, easy to operate, but security is poor slightly.

The purpose of this utility model is at the problems referred to above, provides a kind of need once to move and finishes the sparking process, and be provided with the novel lighter of two place's safety devices on lighter.

The utility model is achieved in that lighter comprises body, hurricane globe, air-valve device, intermediate support, spark generator, and spark generator is made up of flint wheel, rotating shaft, flint, flint spring.Lighter is provided with two place's safety devices.First safety device is located at the flint wheel both sides, is made of the rotating shaft that connects firmly in the flint wheel axis hole, and the rotating shaft maximum gauge is close with the flint wheel diameter or identical.Because this safety device is concordant with the flint wheel cylindrical, not to resemble the side wheel sheet that the flint wheel both sides are stirred in common sparking during sparking, but with thumb by on safety device and flint wheel, firmly pressing down, the thumb that contacts with the safety device flint wheel is directly acted on the flint wheel, stir the flint wheel sparking.Because the flint wheel diameter less than the side wheel sheet diameter of common lighter, wants big so directly stir the power of the common lighter side wheel of the force rate effect sheet of flint wheel.Second safety device of this lighter is located under the lever rear portion of air-valve device, promptly is provided with the damping element that stops lever to press down in the lever rear end bottom space.When depress lever, need apply the bigger power of more common lighter, just can overcome resistance, open air valve.This shows, this lighter is provided with release mechanism respectively in two places of control lighter sparking (stirring flint wheel and following to lever), they need execute bigger power than the common lighter sparking, so this two places safety device has constituted the dual fail-safe security function of this lighter, avoided child fire play very effectively, and, also has security to the unconscious sparking of being grown up.

Two kinds of release mechanisms that the structure of first safety device of the present utility model also can adopt the applicant to be proposed in No. 97219832.6 " safety lighter " application documents replace, be a kind of be the coaxial side wheel sheet of loading onto on the flint wheel both sides, the side wheel sheet cooperates with flint wheel between centers crack, its slightly larger in diameter is in the flint wheel external diameter, another kind is the hurricane globe top to be extended to cover the flint wheel both sides, and it highly equals or is slightly larger than the flint wheel overhead height.

The utlity model has following advantage:

1, two place's safety devices are controlled two elements (flint wheel and lever) that sparking is moved respectively on the lighter.This lighter is more safer than the lighter that has only a safety device.

2, this lighter structure is simple, and is easily manufactured, is suitable for producing in enormous quantities.

3, lighter is easy and simple to handle, does not change common lighter and once moves the mode of operation of igniting, increase dynamics in operating process only.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

With reference to Fig. 1, Fig. 2, the safety lighter is made of body, hurricane globe 5, air-valve device 3, intermediate support 11, spark generator and safety device.Body is made up of oil storage tank 1 and oil groove lid 2.On oil groove lid 2, air-valve device 3 is housed.Air-valve device comprises that fire chews pipe 6, flame adjusting ring 4 and valve opening element and lever 9, and the fulcrum of lever 9 is located on the intermediate support 11.Spark generator comprises flint wheel 7, flint 8, flint spring 12 on intermediate support 11.Safety device has two places, and first safety device is made of the rotating shaft 13 that connects firmly in flint wheel 7 axis holes.Rotating shaft 13 has two, an end of two rotating shafts 13 and the axis hole interference fit of flint wheel 7, and the other end is contained in intermediate support 11 axis holes and is matched in clearance.The maximum gauge of rotating shaft 13 and flint wheel 7 external diameters are roughly the same.Second safety device is to establish a damping element 10 between the bottom, rear end of lever 9 and intermediate support 11, and damping element 10 is a spring, also can be the rubber-like flexible member.During sparking, user's thumb is pressed in rotating shaft 13a and stir at flint wheel 7a place, because the radius of gyration of flint wheel is littler than the radius of gyration of common lighter side wheel sheet, so, need apply the power bigger, could rotate flint wheel 7 and produce spark with flint 8 frictions than common lighter.The 9a that rapidly pushes down lever 9 with thumb exerts oneself downwards then, at this moment, because lever 9 is upwards withstood in the elastic force effect of spring 10, if lever 9 can't be depressed by the dynamics of pushing of common common lighter, only the masterpiece as Shi Gengda is used for lever 9a to pressing down, can make then that spring 10 is compressed, lever 9a moves downward, its other end is provoked fire and is chewed pipe 6 and open air valve combustion gas is lighted.After having played fire, the openhanded lever 9 of opening, each part all reset under system's inner spring power effect, and lighter comes back to safe condition.
