The utility model is characterized in that the press button is fixedly connected with a lock rod having definite elasticity, the head part of the lock rod is extended out of the body, the position of the body, corresponding to the lock rod passing position, is provided with a spacing hole and a guide hole, the two holes are mutually communicated and can be used for containing the head part of the lock rod, the spacing hole can limit that the head part of the lock rod can not move to the lighting position, and the guide hole can allow that the head part of the lock rod can move to the lighting position. The lock rod arranged on the press button, the spacing hole and the guide hole arranged on the body form a safety mechanism, the operation of the igniter is safer, and the operation is convenient.

Description

The lighter safety electronic ignitor

It is the ignition with piezoelectric ignition system of the lighter of fuel, particularly lighter with the liquid gas that the utility model relates to a kind of.

For preventing children, especially young child takes place because of the lighter improper use causes fire incident, the many countries such as the U.S., Canada, Australia and each national capital law-making stipulation of Europe all must be provided with release mechanism at the lighter series products of its market sale, to prevent the generation of accident.In recent years, increasing with the ratio of electronic lighter institute's certificate in lighter gang of piezoelectric ignition system, the igniter that development has a release mechanism becomes a main target in the lighter manufacturing industry.

The purpose of this utility model provides a kind of both safe in utilization, the easy to operate again ignition with new type of safe mechanism.

The utility model is realized in the following way: this lighter electronic igniter comprises body, button, piezoelectric ignition system device, lever, air-valve device.Being connected on button has certain flexible locking bar, and this locking bar head stretches out outside the body.Have spacing hole and pilot hole on the relevant position of passing locking bar on the body, two holes interconnect and can hold the locking bar head, and spacing hole can limit the locking bar head can not be displaced to the sparking position, and pilot hole can allow that the locking bar head is displaced to the sparking position.Locking bar on the button and the spacing hole on the body, pilot hole constitute the release mechanism of igniter.In the normal state, the locking bar head is in the spacing hole, and slightly stretches out body.This moment is if push button, because locking bar is subjected to the restriction of spacing hole, the button that is connected with it can not be moved on the sparking position, thus lighter can not catch fire, thereby play the safeguard protection effect.When needs are struck sparks, must push the locking bar head to pilot hole earlier, make it remove the constraint of spacing hole, push button then to ignition location, produce spark.When pushing button, lever is depressed and disengages combustible gas, and combustible gas and spark meet and catch fire.After finishing igniting, release button, igniter returns back to the normality position, and button also is pushed to the normality position, the locking bar on the button rebounds spacing hole from pilot hole under himself elastic force effect in.Igniter returns back to safe condition.

The utility model compared with prior art has following advantage: 1, security performance is good.Not only children are had good security, and can avoid product in the production and transport process once in a while collision impact lighted.2, simple to operate.The use of this product does not have to change operating habit in the past, only need increase an action consciously and get final product.3, simple in structure, easily manufactured, adapt to and produce in enormous quantities.

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

With reference to Fig. 1, Fig. 2, Fig. 3, this lighter safety electronic ignitor by body 1, piezoelectric ignition system device 3, air-valve device 5, and button 2, lever 4 form.The brace that is connected on the button 2 has certain flexible locking bar 6, locking bar 6 can with button 2 one-body molded (shown in Fig. 7,8).The head 6A of locking bar 6 slightly stretches out outside the body 1.Body 1 is synthetic by 1A, 1B two parts.Have a spacing hole 1C to locking bar on position corresponding with locking bar 6 head 6A on the body 1A, this hole just holds locking bar 6 head 6A.Have the pilot hole 1D that is communicated with spacing hole 1C on body 1B, this pilot hole 1D can not only hold locking bar, and locking bar head 6A is slided along the hole with the motion of button.Be in during locking bar 6 normalities among the spacing hole 1C of body 1 (as shown in Figure 4).During igniting,, then,, also just can not light a fire so button can not move because of the locking bar head 6 on the button 2 is limited by the spacing hole 1C on the body 1A as push button 2 by custom.As before pushing button, elder generation to body 1B direction applied thrust, makes the locking bar 6 on the button produce strains at locking bar head 6A place, and its head 6A is pushed to the pilot hole 1D (as shown in Figure 5) that is positioned at body 1B.Like this, locking bar 6 has just had the space of moving along the button press direction.At this moment, push button 2, button 2 just can move to the ignition location of igniter, produces spark.Locking bar 6 also movement therewith to pilot hole 1D bottom (as shown in Figure 6).When button 2 pressed down, its 2C point was depressed lever 4, opened the valve of air-valve device 5, and combustible gas overflows, and produced flame.After having put fire, release button 2, button just can reset along with resetting of igniter.Locking bar 6 on the button 2 rebounds head 6A among the spacing hole 1C under himself elastic force effect from body pilot hole 1D.Igniter is in home again.

Claims (2)

1, a kind of ignition of lighter, comprise body (1), button (2), piezoelectric ignition system device (3), lever (4), air-valve device (5), it is characterized in that being connected on the button (2) and have certain flexible locking bar (6), locking bar (6) head stretches out outside the body (1), on the relevant position of passing locking bar (6) on the body (1), have spacing hole (1C) and pilot hole (1D), two holes interconnect and can hold locking bar (6) head, spacing hole (1C) can limit locking bar (6) head can not be displaced to the sparking position, and pilot hole (1D) can allow that locking bar (6) head displacement is to the position of striking sparks.

2, the ignition of lighter according to claim 1, two parts are synthetic by (1A) and (1B) to it is characterized in that described body (1), have described spacing hole (1C) on body (1A), have described pilot hole (1D) on body (1B).
