The specific embodiment

Improvement thinking of the present utility model is: the lever motion fulcrum to linked switch is transformed, and linked switch is had can normally do lever motion and lose fulcrum to make the lever motion two states; When linked switch can't be done lever motion, lighter for want of fuel gas can't be lighted a fire; And design the locking spring of suitable pressure, make children can't change this two kinds of duties because of the strength reason.This just is equivalent to install additional one child lock on lighter.Guarantee children's life security with this.

According to this thinking, the structure of original lighter need not change substantially, following high-voltage pulse lead-in wire 2 and the air storing cavity that is arranged in parallel by switch 1, with high-voltage pulse generator that comprises as shown in Figure 1 high-voltage pulse generator 4, high-voltage pulse generator top; Other has a sheet of linked switch lateral arrangement (both the length direction of linked switch was arranged along the orientation, the left and right sides of lighter), the two ends of linked switch are also inserted respectively and are connected the following on switch and the spool of the right and left, so that the two ends of switch are with moving up and down respectively by switch and spool down; These components and parts and concrete structure all are positioned on the machine wall (representing with double dot dash line among the figure) of lighter.

The change that the utility model is done is that the projection of originally using as linked switch lever motion fulcrum is removed; Replace with safety lock in addition.The structure of this safety lock is: a rotating lock core 8 is located in the middle part of described linked switch bottom, and the pivot center of lock core is vertical substantially with the length direction of linked switch; The lock core two ends are cylindrical spindle noses and are supported by the axis hole of two side machine walls 10, and this lock core wherein end of an end also passes through axis hole and connects with the handle 12 of engine body exterior; The middle part of lock core is shaped on eccentric cam 9, and when handle was swung, this eccentric cam was also followed lock core and swung together.Because limited location, this eccentric cam has two states, and one of them state is that the eccentric cam top is near the rotating fulcrum (as shown in Figure 1) of linked switch as linked switch; Another is that eccentric cam rotates 90 degree, and its top is left from linked switch and made lighter be in safety locking state (as shown in Figure 2).

Fig. 1 represents the normal operating conditions that is in of lighter.At this moment, pressing down by switch under the electronic lighter, the pulse fuse above the high-voltage pulse generator is together pressed down; When the electronic lighter switch is depressed into certain position, just be pressed onto the left end of linked switch down by switch, thereby down continue to press down the pulse fuse of not only depressing above the high-voltage pulse generator by switch, and the left end of linked switch is rotated counterclockwise around the top of eccentric cam (with it as balance pivot), the right-hand member of linked switch then makes liquefied gas spray from port lifting on the spool, and the electronic lighter switch continues to press down till liquefied gas is ignited in the high-voltage pulse generator discharge.

The expression lighter is in the safety locking state among Fig. 2.At this moment, when pressing, can depress by the electronic lighter switch pulse fuse above the high-voltage pulse generator, but because eccentric cam 9 has rotated counterclockwise 90 degree, the past following suitable distance that moved in the top of eccentric cam, linked switch has lost the fulcrum of lever activity, can't make on the spool and lift, so the valve lighter of not performing fighting can not be worked.

Fig. 3 to Fig. 5 has shown the situation of each parts when normal operating conditions in the safety lock: the left end of lock core 8 is made square tenon surface 8-2 and cylindrical spindle nose 8-1 (the inscribed circle cylinder that links to each other with square tenon surface), in the square opening and prism of this end insertion machine wall 10; The centre of lock core is provided with the eccentric cam 9 (can see two eccentric cams 9 among the figure, also can merge into an eccentric cam) as the linked switch fulcrum; The lock core right-hand member also is a cylindrical spindle nose and by the circular axis hole supporting of machine wall 10, and this end also passes through circular axis hole and is connected with the handle of machine wall outside; Among the figure as can be known: firm for connecting, the axle head of lock core is shaped on leg-of-mutton groove and is connected (also can adopt other connected mode, as making screw on handle, and fix with screw and lock core axle head) with handle.Spring 11 (steel sheet spring) is installed between the machine wall of the eccentric cam on safety lock right side and lighter, and makes it have the potential energy of past left-hand axis to motion to the lock core application of force (this power should guarantee that children can not be pressed into).When position shown in Figure 3 since the square tenon surface of lock core left end with the machine wall on square hole insert and cooperate, lock core can not rotate, lighter is in the state of operate as normal.At lock core left end axial compressive force F (should greater than spring force) in addition, lock core will overcome spring force and move right (shown in Figure 6), and when the square tenon surface of lock core left square hole on the machine wall, rotatable handles turned over 90 degree clockwise with lock core; Removal power F, lock core will be moved to the left under the effect of spring 11, because the square tenon surface of lock core left end reenters the square hole on the machine wall, safety lock is in the position of Fig. 7.At this moment, on the lock core eccentric cam rotated the disengaging linked switch, be not re-used as the fulcrum of linked switch, linked switch can not be opened valve, lighter is lockable and is in a safe condition.Recover the work of lighter, as long as in addition power F and handle turn over the operate as normal that 90 degree just can recover lighter counterclockwise once more at the left end of lock core.

Obviously, described square tenon surface also can be arranged on the right side of lock core; Spring 11 also can be arranged on the left side of lock core, all has identical effect.In addition, spring 11 also can be provided with at the lock core position, and directly is positioned on the body of lighter the lock core application of force; And do not adopt steel disc formula spring, and adopt other structure (as helical spring), still can reach purpose the lock core application of force.Described these transfer pairs those skilled in the art are conspicuous.

Set suitable spring force, can make children drive the lock housing axially-movable with hand strength, the purpose of safety lock can reach.
