Abstract

The invention relates to a rotation sleeve cover safety device of lighter, wherein it comprises a piezoelectric lighter (1), button (6), and a rotator for resisting the downward motion of button; one point of inner side of rotation sleeve cover is connected to one end of return spring (5); another end of return spring (5) is connected to the spring positioning pin (4); the spring positioning pin (4) is between the button (6) and the piezoelectric lighter (1); said positioning point (3) can position the rotation sleeve cover (2), when the return spring (5) is loose; when lighting, pushing rotation sleeve cover (2) to leave the positioning point (3) to be parallel with button (6); then pushing downwards the rotation sleeve cover (2) to contact the button (6) with piezoelectric lighter (1). The invention adds a rotation step before lighting, to improve the safety.

Description

Rotary sleeve 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; As shown in Figure 1: be a kind of lighter commonly used, main piezoelectrics 1, air storage chamber 10, drive atmospheric pressure pole 9, nozzles 8, high-voltage line 7 and button 6 and form; When button down on time, be pressed onto piezoelectrics, 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 rotary sleeve 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 piezoelectrics, button; Also comprise one can stop button down by rotational structure; Described rotational structure comprises a rotation upper shield, an anchor point of fixing with lighter casing, spring holder, return spring; A bit being connected with an end of return spring of described rotation upper shield inboard, the other end of return spring links to each other with spring holder, and spring holder is placed between button and the piezoelectrics; Described anchor point will rotate upper shield location when return spring is lax; When needs are lighted a fire, promote the rotation upper shield, make the rotation upper shield leave anchor point and parallel with button, contact with piezoelectrics by rotating upper shield and driving button downwards again;

Compared with prior art, the invention has the beneficial effects as follows: owing to before igniting, the step of a rotation 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 piezoelectrics 1, button 6; Also comprise one can stop button down by rotational structure; Described rotational structure comprises 2, one anchor points of fixing with lighter casing 3 of a rotation upper shield, spring holder 4, return spring 5; A bit being connected with an end of return spring 5 of described rotation upper shield 2 inboards, the other end of return spring 5 links to each other with spring holder 4, and spring holder 4 is placed between button 6 and the piezoelectrics 1; Described anchor point 3 will rotate upper shield 2 location when return spring 5 relaxes; When needs are lighted a fire, promote rotation upper shield 2, make rotation upper shield 2 leave anchor point 3 and parallel with button 6, contact with piezoelectrics 1 by rotating upper shield 2 and driving button 6 downwards again.

Lock-out state

Locking-in state is as shown in Figure 3A:

Because the existence of rotation upper shield, the user presses down buttons force and is obstructed, and can not press to normal position, promptly can not start the piezoelectricity fire maker, and this moment, lighter was in the lock state.

Releasing process

Releasing process is shown in Fig. 3 B:

User's application of force upwards promotes the rotation upper shield, will rotate upper shield and progressively be pushed to directly over the button, and lighter is in just progressively release.

Release is finished

The release completion status shown in Fig. 3 C,

The user overlaps rotation upper shield and button (6) to the rotation upper shield application of force fully, and the lighter restriction is eliminated, and release is finished, and lighter can normally be struck sparks.

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

The lighter locking

Shown in Fig. 4 A, button is limited by the rotation upper shield, and the user can not start the piezoelectricity fire maker by the button down application of force, also promptly can not normally strike sparks, and lighter is in the lock state.

The lighter release

Shown in Fig. 4 B, the user rotates up upper shield, and it is progressively overlapped with button, and release is finished.

Lighter is normally struck sparks

Shown in Fig. 4 C, after the user finishes release, guarantee to rotate upper shield and go to dominant bit.

Shown in Fig. 4 D, can push pushbutton enable piezoelectricity fire maker downwards and light the gas that ejects from air storage chamber normal sparking as the sparking press proof.

The lighter reset locking

Shown in Fig. 4 E, the user will rotate under the upper shield and be pushed into raw bits, the locking lighter, and lighter can not normally be struck sparks, and is in the lock state again.

Claims (1)

1. rotary sleeve cover type safety device in the lighter comprises piezoelectrics (1), button (6); It is characterized in that: also comprise one can stop button down by rotational structure; Described rotational structure comprises a rotation upper shield (2), an anchor point (3) of fixing with lighter casing, spring holder (4), return spring (5); What described rotation upper shield (2) was inboard a bit is connected with an end of return spring (5), and the other end of return spring (5) links to each other with spring holder (4), and spring holder (4) is placed between button (6) and the piezoelectrics (1); Described anchor point (3) will rotate upper shield (2) location when return spring (5) is lax; When needs were lighted a fire, promotion rotation upper shield (2) made rotation upper shield (2) leave anchor point (3) and parallel with button (6), contacted with piezoelectrics (1) by rotating upper shield (2) and driving button (6) downwards again.
