Description

The lighter of band Air Valve Control part

The utility model relates to a kind of lighter with the Air Valve Control part.

Lighter commonly used at present is a kind of electronic ignition utensil that utilizes inflammable gases such as butagas, natural gas for fuel, it comprises oil groove, places the piezoelectric device in the oil groove and goes out pneumatic module, wherein piezoelectric device is made of piezoelectric blocks and the hand of pressing that is positioned at its top, usually directly pull during use and press hand with finger, use pneumatic module and discharge inflammable gas, piezoelectric blocks in the piezoelectric device produces the moment heavy current thereupon and sends spark, and then lights flare.Establish skid plate interlock owing to press hand, piezoelectric blocks and go out the pneumatic module three by interior,, very easily light lighter, injury children even endanger public security if when being not intended to maloperation, the child plays or the unexpected percussion lighter of hard object being arranged.Therefore, area that has and country are to the lighter of the system operating mechanism of not limiting or will expressly forbid production and selling.

The purpose of this utility model is to overcome the defective of existing product, provide a kind of with the Air Valve Control part, push and press the lighter that can not discharge inflammable gas behind the hand.

For achieving the above object, the technical solution of the utility model comprises the oil groove that is used for storage of fuels, place the piezoelectric device in the oil groove and go out pneumatic module, wherein piezoelectric device is made of piezoelectric blocks and the hand of pressing that is positioned at its top, make the stressed generation of piezoelectric blocks moment heavy current and produce electric spark by pressing hand down, go out pneumatic module and be used for discharging and closing inflammable gas, it is characterized in that describedly going out pneumatic module and being provided with the Air Valve Control part, this Air Valve Control part one end places out in the pneumatic module, the other end places outside the oil groove, not with press hand interlock, push and to make piezoelectric blocks generation moment heavy current send spark when pressing hand, discharge inflammable gas and can not open out pneumatic module, only press the Air Valve Control part and open out pneumatic module and discharge inflammable gas, push again and press hand and make piezoelectric blocks produce the moment heavy current to send spark and just can light flare.

The lighter of described band Air Valve Control part is characterized in that described Air Valve Control part is one " L " shape skid plate, and skid plate is connected to out in the pneumatic module by bayonet socket, so that this Air Valve Control part single movement is convenient to operation.

The lighter of described band Air Valve Control part is characterized in that the pneumatic module side is provided with locating piece, in case its displacement.

The lighter of described band Air Valve Control part is characterized in that the oil groove top is provided with a support, is used for fixing parts.

The utility model is owing to going out the Air Valve Control part that is provided with single movement on the pneumatic module, existing lighter piezoelectric device and the linkage structure that goes out pneumatic module have been changed, use pneumatic module and press hand and do not have related, push and press hand and can only make piezoelectric blocks produce the moment heavy current to send spark, if not pressing the Air Valve Control part earlier opens out pneumatic module and discharges inflammable gas, just can not light flare, thereby having avoided only pulling presses hand and can light flare and produce potential safety hazard, the lighter security performance is improved, prevent maloperation.

Further specify the utility model below in conjunction with embodiment and Figure of description.

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

Fig. 2 is a safe condition schematic diagram of the present utility model.

Fig. 3 is a working state schematic representation of the present utility model.

As shown in Figure 1; constituting parts of the present utility model has: the oil groove 11 that is used to store inflammable gas; place the piezoelectric device 13 in the oil groove 11 and go out pneumatic module 14; wherein piezoelectric device 13 is made of piezoelectric blocks 8 and the hand 6 of pressing that is positioned at its top; push and press hand 6 and can make piezoelectric blocks 8 produce moment heavy currents to send spark; go out pneumatic module 14 and be provided with air outlet valve 1 and air valve control piece 3; Air Valve Control part 3 is L-shaped; the one end opening is connected to out in the pneumatic module 14; the other end stretches to outside the oil groove 11; pressing Air Valve Control part 3 stretches to the outer ends of oil groove 11 and can open air outlet valve 1 and discharge inflammable gas; the left side of air outlet valve 1 is provided with the displacement that locating piece is used to prevent Air Valve Control part 3; above oil groove 11, be provided with oil groove lid 9; be used to seal inflammable gas; the top of oil groove 9 also is provided with support 2 and is used for fixing the lighter parts; bottom 12 is provided with charge valve and is convenient to replenish inflammable gas in oil groove 11; piezoelectric blocks 8 and press and be provided with piezoelectricity cap 7 between the hand 6 and be used for transmitting power downwards and protecting piezoelectric blocks 8; piezoelectric blocks 8 has rubber blanket 10 and is used to slow down impact to piezoelectric blocks 8; fan housing 4 is used for windproof, is provided with the inner cover 5 that is used to isolate flame in it.Owing to press Air Valve Control part 3 and push that to press hand 6 are two independently actions, do not link between them, therefore can only make when pressing hand 6 piezoelectric blocks 8 produce moment heavy currents to send spark when pressing separately, and can not make air outlet valve 1 discharge inflammable gas, thereby can not light flare, open air outlet valve 1 and discharge inflammable gas, but can only send spark in moment because of piezoelectric blocks 8 even press Air Valve Control part 3 subsequently, still can't light flare, thereby lighter is in a safe condition.

As shown in Figure 2, under the normality, make air outlet valve 1 be in normally off owing to go out to be provided with spring in the pneumatic module 1, then because of air outlet valve 1 be not opened, do not have inflammable gas if press hand 6 as using common lighter to press this moment, and can not light flare, thereby lighter is in a safe condition.

As shown in Figure 3, during igniting, press Air Valve Control part 3 earlier, open air outlet valve 1 and discharge inflammable gas, then press and press hand 6 and make piezoelectric blocks 8 produce sparks can to light flare, pin Air Valve Control part 3 flare is continued; Finish with fire and only need unclamp Air Valve Control part 3, then close air outlet valve 1 under the effect that goes out pneumatic module 1 inner spring, lighter returns to normal.When flare continues, because the igniting action finishes, press hand 6 and make it to reset so can unclamp, need pin Air Valve Control part 3 to get final product, this is improvements of the present utility model.

The utility model includes but not limited to the foregoing description; make in every cancellation existing product piezoelectric device with go out pneumatic module interlock in establish skid plate; directly control out pneumatic module work by independent control piece; making piezoelectric device and go out pneumatic module is come control operation respectively by two actions implementation, all is protection domain of the present utility model.
