Description

Top cover type safety device in the lighter

Technical field

The present invention relates to a kind of lighter, relate 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; Be a kind of lighter commonly used, mainly by button 1, lighter shell 6, pressure rod 7, nozzles 8, high-voltage line 9, button thimble 10 and piezoelectrics 11 and fixedly the transverse slat 12 of piezoelectrics 11 form; One end of transverse slat 12 links to each other with lighter shell 6; 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 11 hull shapes, and middle thimble 101 can touch the loam cake of piezoelectrics 11; Button 1 downwards on time, drive on the button thimble 10 in the middle of a thimble 101 pushed up piezoelectrics 11, piezoelectrics 11 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 technical issues that need to address of the present invention have provided top cover 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 present invention is achieved by the following technical solutions:

The present invention includes button, lighter shell, button thimble, pressure rod, piezoelectrics, transverse slat; First thimble and second thimble are in piezoelectrics hull shape outer in the described button thimble, and the 3rd thimble is between lighter shell and first thimble, and an end and the transverse slat of return spring are fixed; Also comprise an angle in the lower end of described first thimble, one extension rod is arranged in the lower end of angle; The hull shape of piezoelectrics outside, one inclined-plane is arranged with the contact position of angle and extension rod; When needs are lighted a fire, upwards promote button, the angle of first thimble of button thimble is stuck on the piezoelectrics upper surface;

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

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:

As seen from Figure 2: the present invention includes button 1, lighter shell 6, pressure rod 7, button thimble 10, piezoelectrics 11, transverse slat 12; First thimble 101 and second thimble 102 are in piezoelectrics 11 hull shape outers in the described button thimble 10, and the 3rd thimble 103 is between lighter shell 6 and first thimble 101, and an end of return spring 5 and transverse slat 12 are fixing; Also comprise an angle 2 in the lower end of described first thimble 101, an extension rod 3 is arranged in the lower end of angle 2; The hull shape of piezoelectrics 11 outside, an inclined-plane 4 is arranged with the contact position of angle 2 and extension rod 3; When needs are lighted a fire, upwards promote button 1, the angle 2 of first thimble 101 of button thimble 10 is stuck on piezoelectrics 11 upper surfaces;

The gradient on described inclined-plane 4 is corresponding with extension rod 3, and when extension rod 3 downwards the time, angle 2 breaks away from piezoelectrics 11 upper surfaces;

Lock-out state of the present invention

Reset condition as shown in Figure 3A;

Shown in Fig. 3 B-Fig. 3 D:

The user presses down by button 1 application of force, and extension rod 3 touches inclined-plane 4 earlier, and the downslide of postponing touches pressure rod 7 until button thimble 10, with its voltage rise extremely to greatest extent; Because the angle 2 of this moment has been stuck in the piezoelectrics 11 on the end face, button 1 does not reach piezoelectrics 11 all the time, promptly can not start lighter, and the user just has gas not have fire under this state, and this moment, lighter was in the lock state;

Releasing process

Reset condition is shown in Fig. 4 A:

User's application of force that makes progress promotes lighter, places piezoelectrics 11 tops until angle 2, guarantees that lighter can start piezoelectricity fire maker 11, the lighter release;

The sparking process

Shown in Fig. 4 C-Fig. 4 D:

The user presses the button 1 of lighter downwards, angle 2 drives piezoelectrics 11 and presses down, guarantee that lighter can start piezoelectricity fire maker 11, simultaneously second thimble 102 of button thimble 10 presses down and starts pressure rod 7, and lighter can normally be struck sparks there being electricity to have under the situation of gas.

Reseting procedure

Process is shown in Fig. 4 E-Fig. 4 G:

In Fig. 4 E-Fig. 4 F process, the user continues downwards by the button 1 of lighter, and angle 2 presses to inclined-plane 4, continues sparking, contacts fully with piezoelectrics 11 to button 1, reaches at utmost, finishes the preparation of locking; At this moment, because the effect on inclined-plane 4, angle 2 leaves on piezoelectrics 11 upper surfaces; When letting go, because the effect of return spring 5 makes it restore to raw bits, lighter locks once more, shown in Fig. 4 G.

Lighter state of the present invention and use can be divided into following a few part:

The lighter locking

Shown in Fig. 4 A, lighter is in raw bits, is in the lock state, and the user can not start piezoelectrics 11 to button 10 application of forces, and lighter is in the lock state.

The lighter release

Shown in Fig. 4 B, user's application of force that makes progress promotes lighter button 1, places piezoelectrics 11 tops until angle 2, to dominant bit, guarantees that lighter can start piezoelectricity fire maker 11, the lighter release.

The lighter sparking

The whole process of lighter is shown in Fig. 4 C and Fig. 4 D:

The user presses the button 1 of lighter downwards, angle 2 drives piezoelectrics 11 and presses down, guarantee that lighter can start piezoelectricity fire maker 11, simultaneously second thimble 102 of button thimble 10 presses down and starts pressure rod 7, and lighter can normally be struck sparks there being electricity to have under the situation of gas.

The lighter reset locking

Shown in Fig. 4 E-Fig. 4 F: the user continues downwards by the button 1 of lighter, and angle 2 presses to inclined-plane 4, continues sparking, contacts fully with piezoelectrics (11) to button (1), reaches at utmost, finishes the preparation of locking;

Shown in Fig. 4 G, the user decontrols button 1, makes it restore to raw bits, and lighter locks once more.
