Description

A kind of safety lighter

Technical field

The utility model relates to lighter, relates in particular to a kind of safety lighter.

Background technology

General known simple type lighter comprises fuselage; head; on head, be provided with nozzles; fire ring; fan housing; the lever pressing plate; spring; flint; support and sparking wheels; the middle wheel of sparking wheels; cincture (comprising axis) is fixed together; rotate simultaneously; stop simultaneously; and wheel is high slightly in the cincture ratio; wheel in the user can rotate simultaneously with general strength; cincture (comprising axis); wheel produces spark with flint generation friction in making; to discharge fuel if press down pressing plate simultaneously; can reach the purpose of lighting lighter, but this type of simple and easy lighter can not prevent effectively that children from playing or because of taking turns in the unintentional rotation; cincture produces that spark causes lighting lighter and all kinds of danger that take place.

Be safe handling, prevent the danger that the mistake combustion produces, previous various corrective measures are concluded following several:

(1) cincture and middle wheel combine as a whole, but can separate with axis, and the gap of axis and middle wheel, cincture is bigger.In addition, the outside of cincture (with the contact-making surface of thumb) has little tooth.The characteristics of this corrective measure are the securities that strengthens lighter by the strength that increases wheel in the rotation.But the shortcoming of this corrective measure is: because the gap of axis and middle wheel, cincture is bigger, and there is little tooth in the outside of cincture, thus need relatively large strength to take turns in could rotating, Just because of this, the practicality of this corrective measure is not strong, is difficult in practice promote.

(2) interior 2/3 of the side of wheel and axis, cincture combines as a whole in, and outer 1/3 and former three of middle wheel do not rotated simultaneously or stopped.In wheel outer 1/3 and interior 2/3 between significantly gap is arranged, both are discerptible, the former is embedded on the latter, the security performance of this corrective measure is better, but comparatively speaking, its manufacturing, design difficulty are bigger, cause cost to strengthen, the profit reduction.

(3) method of increase components and parts strengthens the security performance of lighter, as utilize the depression on the fuselage top of existing simple type lighter lever pressing plate below, increase the shell fragment control piece newly and constitute one group of safety switch, one vertical follow block is arranged below the front end of this control piece, and (annotate: this follow block is up-narrow and down-wide, upper-thin-lower-thick), the plate body of control piece is provided with an impenetrating mouth, the dislocation state that the projection of utilizing control piece at ordinary times to be positioned at the impenetrating mouth of the top plate body when the next and lever pressing plate lower end forms, make the lever pressing plate not press down, reach the safe effect that gas can't be excessive.If but inwardly push away and on when lifting control piece, then the impenetrating mouth of control piece plate body just in time upwards entangles on the projection of lever pressing plate below, make control piece can not bring into play the effect that stops, this moment, the lever pressing plate was fallen together with control piece, and gas is released for igniting.And when rising on the lever clamp loose position, utilize then that the control piece follow block is up-narrow and down-wide, the mutual squeezing action of the features of shape of upper-thin-lower-thick and shell fragment, make control piece maintain lower position, the projection of the lever pressing plate lower end after rise this moment is misplaced with the impenetrating mouth of control piece top plate body once more, recovers the safe condition that the lever pressing plate can't press down.Certain security performance that strengthens lighter of this kind corrective measure, but the increase of its design, manufacturing cost also is conspicuous.

No matter adopt above-mentioned which kind of scheme, all exist because of design, assembling, raw-material increase cause cost and improve, the obvious decline of the rising of selling price or profit, thereby be difficult to the drawback promoted in practice.The utility model content
