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 arranged at both sides of the lighter. Two modes are supplied: one mode is that both sides of the lighter are coaxially and respectively provided with a side wheel slice matched with a rotating shaft in a clearance fit mode, and the diameter of the side wheel slice is a little more than the outer diameter of a strike fire wheel; the other mode is that the top of the wind proof cover extends to be covered on both sides of the strike fire wheel, and the height of the wind proof cover is equal to or a little more than the height of the top of the strike fire wheel. The safety lighter finishes striking fire for one time, the simple structure, and the operation is convenient.

Description

Safety lighter

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

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 on its domestic market must be provided with safety device.Various in recent years safety lighters constantly are pushed to the market.If the number of times by the sparking action divides, these safety lighters roughly can be divided into two classes: a class is that the sparking action needs two actions just can finish.The characteristics of this class lighter are that security is higher, but troublesome poeration, the consumer is difficult for accepting.Another kind of is that sparking does not have tangible two actions.The characteristics of this class lighter are simple in structure, easy to operate under the prerequisite that guarantees security, and the consumer is easy to accept.

The purpose of this utility model provides a kind of need and once moves the lighter that is provided with the new type of safe device of finishing the sparking process.

The utility model is achieved in that lighter comprises body, hurricane globe, air-valve device, intermediate support, spark generator.Spark generator is made up of flint wheel, rotating shaft, flint, flint spring.Safety device is located at the both sides of flint wheel.This safety device can have dual mode, and the first is the coaxial side wheel sheet of loading onto on the both sides of flint wheel, side wheel sheet and rotating shaft matched in clearance, and its slightly larger in diameter is in the external diameter of flint wheel; It two 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.During sparking, by firmly pressing down on safety device and flint wheel, make the thumb skin that contacts with safety device and flint wheel produce distortion with thumb, the skin of distortion directly acts on the flint wheel, stirs flint wheel friction flint and produces spark ignition.If strike sparks by common sparking mode, be that the thumb flicking is on the safety device of flint wheel and both sides thereof, although thumb skin also can produce distortion, because the power that acts on the flint wheel is less, be not enough to stir flint wheel, also just can not produce spark ignition by the friction flint.So the utility model only needs once action just to finish the sparking process, but need increase consciously to push dynamics and will consciously masterpiece be used on the flint wheel when striking sparks owing to this lighter, this not only can be avoided child fire play, and the unconscious sparking of being grown up is also had security.

The utlity model has following advantage:

1, easy and simple to handle.Only need to increase consciously the application point that presses down dynamics and notice during sparking, once action just can be finished the sparking process.

2, simple in structure, make easily low cost of manufacture.

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the structural representation of the utility model embodiment 2;

Fig. 4 is the left view of Fig. 3.

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

Embodiment 1:

With reference to Fig. 1, Fig. 2, the safety lighter is made of body, hurricane globe 5, air-valve device 3, intermediate support 10, 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, adjustable ring 4 and valve opening lever 9.The fulcrum of lever 9 is located on the intermediate support 10.Spark generator is made up of flint wheel 7, rotating shaft 12, flint 8 and fiery flint spring 11.Whole spark generator is contained on the intermediate support 10.Safety device i.e. two side wheel sheets 13 is enclosed within respectively in the rotating shaft 12 of flint wheel 7 both sides, and with rotating shaft 12 matched in clearance.Rotating shaft 12 has 2, and an end of two rotating shafts connects with the endoporus of flint wheel 7 is fastening, the other end be contained in the axis hole of intermediate support 10 and with the axis hole matched in clearance.Two rotating shafts 12 and flint wheel 7 can rotate in intermediate support 10 together, and side wheel sheet 13 can not drive rotating shaft 12 when rotating and flint wheel rotates together.The slightly larger in diameter of side wheel sheet 13 is in the external diameter of flint wheel 7.When sparking, user's thumb is pressed in the 13a place of side wheel sheet 13 and the 7a place and the rotation of flint wheel 7.If according to common sparking method, the power that promptly is pressed on side wheel sheet 13 and the flint wheel 7 is little, and mainly is to drive the flint wheel sparking by rotating the side wheel sheet, as mentioned above, because the rotation of side wheel sheet can not drive rotating shaft and flint wheel rotates together, so can't strike sparks.Has only off the beaten track sparking method, on side wheel sheet 13a and flint wheel 7a, apply bigger pressure, make the skin of thumb produce distortion and allow this skin that partly is out of shape directly stir flint wheel 7 consciously, flint wheel 7 rotates with flint 8 frictions and produces spark.Depress lever 9 then rapidly, provoke fire and chew pipe 6, open air valve combustion gas is lighted.Behind fire, the openhanded lever 9 of opening, fire are chewed pipe 6 and are resetted under the elastic force effect of air-valve device 3, drive lever 9 simultaneously and reset, and lighter is got back to original state.

Implement 2:

With reference to Fig. 3, Fig. 4, present embodiment has been cancelled the side wheel sheet 13 of embodiment 1, and its safety device is replaced by hurricane globe 5.The top of hurricane globe 5 extends to the 5a place to the both sides of flint wheel 7, and it highly is equal to or greater than the overhead height of flint wheel.All the other structures are with embodiment 1.During sparking, finger must be pressed in flint wheel 7a and hurricane globe 5a place, and directly stirs flint wheel 7 consciously, just can strike sparks.As by common sparking method, there is not enough pressure, then can not stir flint wheel 7, thereby can't strike sparks.
