The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

In conjunction with Fig. 1-shown in Figure 6, the utility model lighter safety ignitor mainly comprises pressing lid 1, one depression bar 2 and a spring 12, wherein:

Pressing lid 1 is made the branch body structure, include a pedestal 13 and a lid 11, wherein a side of pedestal 13 relative lighter fan housings 5 convexes with two and rise to connect and button pin 131, the two button pin 131 of guide effect snap onto in the fan housing 5 of lighter, makes pedestal 13 slippage about the fan housing inwall.What the top of pedestal 13 was provided with that two jacks that are arranged in parallel 132 and are used for placing spring puts seat 133.Lid 11 is the lids that are corresponding pedestal 13 top shape, and can cover pedestal, and described spring 12 is positioned at the inside of both combinations.Two pins 111 that protrude are downwards arranged at described lid 11 bottoms, and pin inserts in two jacks 132 at pedestal top, and lid 11 inwardly or is outwards passed along the jack of pedestal.On two pins 111 of lid a jack 112 is arranged respectively, but voltage supply bar 2 is pegged graft.

Depression bar 2 is made demihull shape, its upper end is plugged in the slot 112 of lid pin, the lower end correspondence is positioned at the shoulder rank 32 of the Piezoelectric switches housing 3 of its below, and the distance between depression bar 2 lower end surface and this shoulder rank is less than the igniting stroke of igniter, like this because the barrier effect of these 31 pairs of depression bars 2 in shoulder rank, make the user under, pressing can't be covered 1 and press down and do not reach igniting stroke, i.e. akinesia ignition switch not with lid 11 outside passing states.Have only after lid 11 outside the passing, the user just can push pressing lid 1 downwards, and the igniting connector 4 that is driven in the Piezoelectric switches by pressing lid 1 moves, and can produce the percussion igniting.The connector 4 of wherein lighting a fire is a lever member, and the both sides of fork-shaped head are hubbed on the two side of lighter shell, and afterbody heads on the pedestal 13 of pressing lid, and the middle part is the top that fulcrum leans against the Piezoelectric switches housing.
