Abstract

The utility model involves in a kind of shell rotary type safety device of lighter including air receiver 5, piezolighter 9, button 10 and shell 12. The bottom of button 10 includes the first thimble 101 and the third thimble 103 near the shell 12. The shell 12 is divided into top shell 120 and bottom shell 121 and rotates at an angle by rotary venthole 6 which connects top shell with bottom shell. A stop extending hole 7 is arranged at top shell 120 opposite to the third thimble 103. The button 10 will be pressed down when top shell and bottom shell are surfacing, then the third thimble 103 holds out of the hole 7 and is stopped by top of bottom shell 121, so the first thimble 101 can not push the piezolighter 9 completely. The third thimble 103 holds out of the hole 7 when top shell and bottom shell are angulated, and ignition is successful. The step of upwhirlling the shell before agitation strengthens the security.

Description

Lighter middle shell rotation safeties

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 by nozzles 1, pressure rod 2, air storage chamber 5, piezoelectrics 9, button 10, high-voltage line 11, casing 12; Its button 10 bottoms 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 11; Button 10 drives middle thimble 101 and has pushed up piezoelectrics 9 downwards on time, and piezoelectrics 9 are to pressing down, and 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 a kind of lighter middle shell rotation safeties, 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 air storage chamber, piezoelectrics, button, casing; First thimble in the middle of described button bottom comprises, the 3rd thimble of second thimble and close casing; Described casing is divided into upper casing and lower casing, and does the rotation of certain angle by the rotation passage that connects upper and lower casing; There is a stop bit to stretch out the hole at the upper casing place relative with the 3rd thimble; When upper and lower casing becomes a plane, press the button, the 3rd thimble stretches out the hole and by the top stop bit of lower casing, first thimble can not press down piezoelectrics fully; When upper and lower casing at angle the time, press the button, the 3rd thimble stretches out the hole, and first thimble can press down piezoelectrics fully;

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

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 air storage chamber 5, piezoelectrics 9, button 10, casing 12; The 3rd thimble 103 of first thimble, 101, the second thimbles 102 and close casing 12 in the middle of described button 10 bottoms comprise; Described casing 12 is divided into upper casing 120 and lower casing 121, and does the rotation of certain angle by the rotation passage 6 that connects upper and lower casing; There is a stop bit to stretch out hole 7 at upper casing 120 places relative with the 3rd thimble 103; When upper and lower casing becomes a plane, press the button that 10, the three thimbles 103 stretch out hole 7 and by the top stop bit of lower casing 121, first thimble 101 can not press down piezoelectrics 9 fully; When upper and lower casing at angle the time, press the button 10, the three thimbles 103 and stretch out hole 7, the first thimbles 101 and can press down piezoelectrics 9 fully;

Ignition distance when the distance that the lower end of described the 3rd thimble 103 and stop bit stretch out hole 7 presses down less than piezoelectrics 9;

The utility model lock-out state

As shown in Figure 3A:

Because the existence of the 3rd thimble 103, the user presses down button 10 application of forces, and the 3rd thimble 103 stretches out hole 7 from stop bit and stretches out, be hampered by the air storage chamber shell of lighter bottom, can not press to normal position, promptly can not start piezoelectrics 9, this moment, lighter was in the lock state;

Releasing process

Releasing process is shown in Fig. 3 B, Fig. 3 C:

User's application of force rotation lighter forms alternate angle, and when the user presses down button 10 application of forces, it is extended that the 3rd thimble 103 stretches out hole 7 from stop bit, the air storage chamber shell restriction that breaks away from the lighter bottom, and lighter can start piezoelectrics 9, the lighter release;

The utility model lighter state and use can be divided into following a few part:

The lighter locking

As shown in Figure 3A, lighter is in raw bits, and the user can not start piezoelectrics 9 to button 10 application of forces, also promptly can not excite air storage chamber 5 normally to strike sparks, and lighter is in the lock state.

Lighter rotation release

Shown in Fig. 3 B, the user rotates this lighter top, forms alternate angle, and the lighter release is finished;

Shown in Fig. 3 C, by rotation, the 3rd thimble 103 stretches out hole 7 from stop bit and exposes, and breaks away from the air storage chamber shell restriction of lighter bottom, and the user can touch the button down, guarantees that the user normally strikes sparks.

Lighter is normally struck sparks

Shown in Fig. 4 D, can be the same as lighter, normal sparking.

The lighter reset locking

Shown in Fig. 4 E, the user will rotate lighter to original position, and lighter can not normally be struck sparks, and is in the lock state again.
