Description

Blocking button type safety device in the lighter

Technical field

The utility model relates to a kind of lighter, relates in particular in this lighter at prefiring safeties.

Background technology

The U.S. carried out the CR bill comprehensively in 1994 in the world, European Union adds after-tax from the import of nineteen ninety-five and twice pair of disposable lighter in 1999, had passed through the rules (CR bill) that the lighter below 2 Euros must install safety lock additional in 2002.So-called CR (CHILDR ESISTANCE) bill is meant to install additional on lighter and prevents the child device, to improve the lighter security performance.

Existing lighter has various styles, the lid of unlatching and the button of igniting also be have a variety of; As seen from Figure 1: be a kind of lighter commonly used, mainly form by button 1, nozzles 6, pressure rod 7, air storage chamber 8, piezoelectrics 9, button thimble 10.Its button thimble 10 as if " mountain " word that falls, the width of the thimble on two limits (102,103) is bigger slightly than the width of piezoelectrics 9 hull shapes, and middle thimble 101 can touch the loam cake of piezoelectrics 9; Button 1 downwards on time, drive on the button thimble 10 in the middle of a thimble 101 pushed up piezoelectrics 9, piezoelectrics 9 are to pressing down, at this moment lighter just can fire.But the lighter of this style is disadvantageous to 5 years old children, because he can light a fire very easily, brings hidden danger to safety.

Summary of the invention

The utility model technical issues that need to address have provided blocking button type safety device in a kind of lighter, are intended to solve above-mentioned defective.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises button, piezoelectrics, button thimble; First thimble in the middle of described button thimble comprises, second thimble and three thimble close with shell; An axle is installed on described the 3rd thimble; Also comprise a clasp; One end of described clasp can located with the opposite position anchor point of the close shell of thimble, and the other end of clasp joins by retainer spring and axle; When an end of clasp on anchor point, the button thimble blocks; When an end of clasp move on to second thimble nearby, the button thimble can be to pressing down;

Compared with prior art, the beneficial effects of the utility model are: owing to before igniting the step that upwards promotes clasp is arranged earlier, added a lock to safety, guaranteed the thin children of the awareness of safety success of can't striking sparks, guaranteed the safety of the person and property.

Fig. 1 is the lighter structure figure of prior art;

Fig. 2 adopts lighter of the present utility model;

Fig. 3 A to Fig. 3 E is lighter release, sparking, recuperation figure;

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As seen from Figure 2: the utility model comprises button 1, piezoelectrics 9, button thimble 10; First thimble 101 in the middle of described button thimble 10 comprises, second thimble 102 close and the 3rd thimble 103 with shell; An axle 2 is installed on described the 3rd thimble 103; Also comprise a clasp 4; One end of described clasp 4 can located with the opposite position anchor point 5 of thimble 102 close shells, and the other end of clasp 4 joins by retainer spring 3 and axle 2; When an end of clasp 4 on anchor point 5, button thimble 10 blocks; When an end of clasp 4 move on to second thimble 102 nearby, button thimble 10 can be to pressing down.

Principle of the present utility model is as follows:

When clasp was fixed on the anchor point, user's application of force push button because button is connected by the point on the axle with clasp, can't triggers piezoelectrics and excite the interior fuel of air storage chamber, and this moment, lighter was in the lock state;

The user promotes clasp and breaks away from anchor point around axle Rotate 180 degree, the user is application of force push button again, can trigger the piezoelectricity fire maker, excites to generate the electronics fire, simultaneously the pressure rod application of force is excited gas in the air storage chamber, lighter can normally be struck sparks there being electricity to have under the situation of gas;

The user promotes clasp and is rotated under the retainer spring effect around axle, returns to anchor point below, but lighter reset locking again then.Lighter state of the present utility model and use can be divided into following a few part:

The lighter locking

As shown in Figure 3A, clasp is in the lock state, lighter is in locking bit, user's application of force push button, because button is connected by the point on the axle with clasp, and is in the both sides of axle, can't press down piezoelectrics, promptly lighter is under the state that does not have the no gas of fire under this state, and this moment, lighter was in the lock state.

The lighter release

Shown in Fig. 3 B and Fig. 3 C, user's release clasp, method is: the user promotes clasp and breaks away from the some Rotate 180 degree of anchor point on the axle, the homonymy that clasp and button are positioned at spool, the user can touch the button down, then lighter release.

The lighter sparking

The whole process of lighter is shown in Fig. 3 D, and user's application of force push button can trigger the piezoelectricity fire maker, excites to generate the electronics fire, simultaneously the pressure rod application of force is excited gas in the air storage chamber, and lighter can normally be struck sparks there being electricity to have under the situation of gas.

The lighter reset locking

The reseting procedure of lighter is shown in Fig. 3 E: the user only needs to be positioned at clasp and returns to original horizontal position, is in the both sides of axle with button, and piezoelectrics can't press down, and then lighter locks once more.

Claims (1)
