Description

Safety lighter

Technical field

The utility model relates to a kind of lighter, specifically is the safety lighter that a kind of children of preventing play and strike sparks by mistake.

Background technology

Existing common steel wheel lighter is made up of the casing and the sparking assembly of carrying fuel tube, the sparking component assembling is above the casing of carrying fuel tube, the sparking assembly mainly is made up of friction wheel and the flint wheel that is fixedly mounted on the friction wheel both sides, two outsides of flint wheel are provided with installation shaft and are installed in rotation in the installing hole that the lighter head both sides are provided with, be provided with straight trough under the friction wheel, and in this straight trough spring is housed, spring top is equipped with flint and friction wheel Elastic Contact.Dial the rotation of commentaries on classics flint wheel drive friction wheel by thumb during sparking and send spark with the friction flint, thereby simultaneously make the air outlet valve exhaust make spark ignition gas by skid plate under the thumb, though as long as pushing a little to the sparking wheel assembly, thumb just can realize striking sparks during the sparking of the lighter of this structure.But this lighter just exists very big dangerous hidden danger to the very strong children of curiosity. at an easy rate, the lighter that does not just need great finger strength just can light if allow child take and light, is bred disaster probably.

Have some countries just the lighter product to be formulated safety standard as the U.S. now, the unsafe lighter of this use does not allow to come into the market to sell.Therefore, the safety lighter that prevents the sparking of child's mistake that has occurred various structures on the market.Conclusion gets up to have following several:

(1) the big and wheel that skids that be slidingly matched with interior wheel shaft than flint wheel diameter is installed on the interior wheel shaft between flint wheel and the friction wheel, utilize the characteristics that adult's thumb is bigger than child thumb and muscle is strong, when the adult strikes sparks, its thumb can be simultaneously by being pressed on skid wheel and the flint wheel, dialling changes skid wheel and flint wheel drive friction wheel, friction wheel and flint is rubbed produce spark ignition gas; Child is little because of its thumb, can only go up and can not be pressed into flint wheel by being pressed in the wheel that skids, and forms to skid and can't drive friction wheel and rotate igniting.As Chinese utility model patent " the wheeled safety lighter of a kind of friction " (notification number CN2826195Y, open October 11 2006 date); And similar also has Chinese utility model patent " slipping type safety-type lighter " (notification number CN2874288Y, open on 02 28th, 2007 date), but the shortcoming of these two kinds of corrective measures is: owing to skid wheel between flint wheel and friction wheel, exceed flint wheel, the muscle of adult's finger will contact flint wheel needs relatively large strength could rotate friction wheel, the hand skin that is easy to rub brokenly, Just because of this, the practicality of this corrective measure is not strong, is difficult in practice promote.

(2) the flint wheel separate type of friction wheel and both sides is established center hole on the flint wheel, and corresponding with it axle upper edge circumference is shaped on the arc tooth equably.Flint wheel can slide by the arc tooth, also can drive friction wheel rotates, as Chinese utility model patent " lighter to children's safety of cincture inner wall smooth " (notification number CN2397378Y, open on 09 20th, 2000 date), its sliding of such structure is poor slightly, and structure is still simple inadequately.

Summary of the invention

Technical problem to be solved in the utility model is to improve the deficiencies in the prior art, provide more uniform and stable of a kind of rotation, and sliding effect is good, can effectively prevent the safety lighter of children's mistake sparking.When applying the operating physical force that differs in size, can in rotation process, form and slide or follow and rotate two kinds of different kenels, thereby produce igniting and the different differences that misfire, to prevent the play safe effectiveness of lighter of children.

The technical solution of the utility model is:

A kind of safety lighter is made up of the casing and the sparking assembly of carrying fuel tube, and the sparking component assembling is above casing, and the sparking assembly is provided with nozzles, fan housing, lever pressing plate, spring, flint, support, flint wheel and friction wheel; Be provided with straight trough under the described friction wheel, and in this straight trough spring be housed, spring top is equipped with flint and friction wheel Elastic Contact, is used for producing spark with the flint friction; Flint wheel has two, and symmetry is packed in the friction wheel both sides and is bridged on interlock on the support with friction wheel with rotating shaft respectively; The end outside of two flint wheels all has the wheel shaft of boss scalariform again, and two wheels that skid are socketed in respectively on the wheel shaft of this two flint wheel, and near flint wheel; Skid the diameter of wheel greater than the flint wheel diameter, make both form difference in height, the internal diameter of the wheel that skids is a bit larger tham the wheel shaft external diameter of flint wheel and forms pulley and rotates;

The utility model owing to adopted is equipped with the version of and skid wheel that with felling axe be slidingly matched bigger than flint wheel diameter on the felling axe of two flint wheels, utilize the characteristics that adult's thumb is bigger than child thumb and muscle is strong, when the adult strikes sparks, its thumb can be simultaneously by being pressed on skid wheel and the flint wheel, dialling changes skid wheel and flint wheel drive friction wheel, friction wheel and flint is rubbed produce spark ignition gas; And child is when striking sparks, and is smaller because of its thumb, can only go up and can not be pressed into flint wheel by being pressed in the wheel that skids, thereby form skidding, also just can't drive the friction wheel rotation, so also just can not successfully strike sparks.Compared with prior art, the utility model can obviously strengthen the security protection effect of lighter not changing original simple type lighter structure fully, not increasing under the prerequisite of any components and parts;
