Abstract

The utility model relates to an air outlet valve structure of a lighter, which has low manufacture cost and comprises a turnbuckle, a small rubber ring, a spring, a gas-out needle, a rubber stopper, a rubber sleeve, a big rubber ring and a base. The inner cavity of the turnbuckle accommodates the small rubber ring and the spring. The inner cavity of the turnbuckle accommodates part of the gas-out needle, and the front end of the gas-out needle penetrates an opening of the turnbuckle. A flange of the gas-out needle is abutted against the spring. The rubber stopper closes the gas vent of the gas-out needle from the back end. The inner cavity of the rubber sleeve accommodates the rubber stopper, and part of the base is inserted into the inner cavity of the rubber sleeve from the back end. The rubber stopper covers the gas vent of the inner cavity of the rubber sleeve. The big rubber ring is sheathed on the back end of the rubber sleeve and is clamped by the base and the rubber sleeve. The base and the rubber sleeve of the utility model are two discrete components. The plastic can be the material of the rubber sleeve. The utility model can adopt the mode of injection molding and can be implemented in the mode of large bulk production. Besides, the rubber sleeve is made of plastic. Thus, 60% of copper using quantity can be reduced, which reduces the manufacturing cost of the utility model.

Description

The lighter valve arrangement

[technical field]

The utility model relates to a kind of valve arrangement, particularly a kind of lighter valve arrangement.

[background technology]

See also Fig. 1 and Fig. 2, present lighter valve arrangement generally includes turnbuckle 1, small rubber circle 2, spring 3, air-out needle 4, rubber stopper 5, go to the bottom cover 6 and big rubber ring 7.The inner chamber 10 of turnbuckle 1 is equipped with small rubber circle 2 and spring 3.Air-out needle 4 parts are contained in the inner chamber 10 of turnbuckle 1, and its front end passes from the opening 11 of turnbuckle 1.The flange 40 of this air-out needle 4 is against spring 3.Rubber stopper 5 clogs the passage 41 of air-out needle 4 from the rear end.Cover 6 the inner chamber 60 of going to the bottom holds rubber stopper 5, and big rubber ring 7 is enclosed within the groove 61 of the cover 6 of going to the bottom.Because the elastic compression rubber stopper 5 of spring 3 makes rubber stopper 5 cover and goes to the bottom and overlaps 6 passage 62.Small rubber circle 2 plays the effect of sealing air-out needle 4.When this air outlet valve structure was packed lighter into, small rubber circle 2, rubber stopper 5 and big rubber ring 7 sealed, and can prevent gas leakage.

The cover 6 of going to the bottom of this type of lighter valve body only limits to use the copper metal material, and needs to use the machine tooling manufacturing, therefore needs a large amount of copper metal materials of loss, and yields poorly, involves great expense, and need to clean up and can use with gasoline.

[utility model content]

The purpose of this utility model is to provide a kind of lighter valve arrangement of low cost of manufacture.

The utility model is achieved by the following technical solution: this lighter valve arrangement comprises turnbuckle, small rubber circle, spring, air-out needle, rubber stopper, gum cover, big rubber ring and base.The inner chamber of turnbuckle holds small rubber circle and spring.Air-out needle partly is contained in the inner chamber of turnbuckle, and its front end passes from the opening of turnbuckle.The flange of this air-out needle is against spring.Rubber stopper clogs the passage of air-out needle from the rear end.The inner chamber of gum cover holds rubber stopper.Base is installed on the rear end of gum cover, and the passage of this base is covered by rubber stopper, and big rubber ring is between base and gum cover.

Compared to prior art, base of the present utility model and gum cover are two discrete components, and the material of gum cover can be plastics, can adopt injection mo(u)lding, can produce in enormous quantities.Gum cover adopts the plastics manufacturing in addition, can reduce by 60% copper consumption, makes manufacturing cost of the present utility model reduce.

[specific embodiment]

See also Fig. 3 and Fig. 4, a kind of lighter valve arrangement of low cost of manufacture, it comprises turnbuckle 80, small rubber circle 81, spring 82, air-out needle 83, rubber stopper 84, gum cover 85, big rubber ring 86 and base 87.The inner chamber 800 of turnbuckle 80 holds small rubber circle 81 and spring 82.Air-out needle 83 parts are contained in the inner chamber 800 of turnbuckle 80, and its front end passes from the opening of turnbuckle 80.The flange 830 of this air-out needle 83 is against spring 82.Rubber stopper 84 clogs the passage 831 of air-out needle 83 from the rear end.The inner chamber 850 of gum cover 85 holds rubber stopper 84, and base 87 is filled in the inner chamber 850 of gum cover 85 from rear end part, and its passage 870 is covered by rubber stopper 84.Big rubber ring 86 is enclosed within the rear end of gum cover 85, and is clamped by base 87 and gum cover 85.Because the elastic compression rubber stopper 84 of spring 82 makes rubber stopper 84 cover the passage 870 of base 87.Small rubber circle 81 plays the effect of sealing air-out needle 83.When this air outlet valve structure was packed lighter into, small rubber circle 81, rubber stopper 82 and big rubber ring 86 sealed, and can prevent gas leakage.

Base 87 of the present utility model is two discrete components with gum cover 85, and the material of gum cover 85 is plastics, can adopt injection mo(u)lding, can produce in enormous quantities.Gum cover 85 adopts the plastics manufacturing in addition, can reduce by 60% copper consumption, makes manufacturing cost of the present utility model reduce.

Although the utility model is to describe with reference to specific embodiment, this description and not meaning that is construed as limiting the utility model.With reference to description of the present utility model, other of the disclosed embodiments change, and all can expect for those skilled in the art.Therefore, such variation should not break away from affiliated claim institute's restricted portion and spirit.
