Abstract
The present invention relates to a gas charging and sealing mechanism for a lighter, which comprises a mechanism body (1), a spring (2), a valve body (3), a rubber ring (4) and a valve sleeve (5), wherein the rubber ring (4) is arranged between the upper surface of the valve sleeve (5) and the lower surfaces of a thick shaft (3-2) of the valve body (3) to form a sealing structure. The upper surface of the valve sleeve (5) and the lower surface of the thick shaft (3-2) are all conical surfaces with an angle alpha; the conical surfaces can compress the rubber ring (4) to form high-efficiency sealing. The structure can effectively prevent fuel gas already injected in a machine casing from leaking out.
Description
The present invention relates to a kind of lighter, particularly relate to the gas-flow closure mechanism in a kind of lighter.
At present, what inflatable lighter gas-flow closure mechanism adopted is that sealing ring is pushed down on two planes, the shortcoming of this structure is to have gas to release, instantiation is, have the lighter of outlet to be found after several weeks, the gas that was full of fuel in the lighter has originally lacked a lot, has illustrated that gas releases, thereby this mechanism truly has improved necessity.
The object of the present invention is to provide a kind of improved gas-flow closure mechanism, the fuel gas that charges in the lighter is compared with existing mechanism be difficult for releasing.
The objective of the invention is such realization, gas-flow closure mechanism in a kind of lighter promptly is provided, include fuselage, spring, valve body, cushion rubber, valve sleeve, wherein cushion rubber is arranged between the lower surface of the upper surface of valve sleeve and the thick axle of valve body, constitutes hermetically-sealed construction, and the upper surface of valve sleeve is that the lower surface of top taper seat big below little and the thick axle of valve body is to be that following taper seat big above little and the two form a α angle.
The advantage of apparatus of the present invention is, improves the shape and structure of the thick axle of valve sleeve and valve body, makes the fuel gas in it be difficult for revealing, and has improved product quality.
Below in conjunction with accompanying drawing, describe embodiments of the invention in detail, wherein:
Fig. 1 is the structure key diagram of gas-flow closure mechanism in the lighter of the present invention;
Fig. 2 is the key diagram of fuel gas by gas-flow closure of the present invention mechanism.
Consult Fig. 1, Fig. 1 is the structure key diagram of gas-flow closure mechanism in the lighter of the present invention, this mechanism includes fuselage 1, spring 2, valve body 3, cushion rubber 4, valve sleeve 5, wherein, fuselage 1 structure of lighter comprises that from the valve seat part of the valve body 3 of shell in the middle of lighter, the valve body 3 of middle font is placed in the valve seat, the bottom guide shaft 3-1 of valve body 3 penetrates in the center through hole of valve sleeve 5, guide shaft 3-1 can move up and down in the center through hole of valve sleeve 5 vertically, and the thick axle 3-2 of central authorities of valve body 3 is at the middle part of valve body 3, can moving up and down and move with guide shaft 3-1, the top of valve body 3 is to go up axle 3-3, the outside of last axle 3-3 is with spring 2, and the upper wall of the valve seat endoporus of fuselage is withstood in the upper end of spring 2, and the upper surface of 3 thick 3-2 of valve body is withstood in the lower end of spring 2, spring 2 just is confined state when assembling, thereby valve body 3 is produced the elastic force that moves down.Valve sleeve 5 can be made by industrial plastic, can be to make with fuselage 1 identical materials, can adopt modes such as ultrasonic bonding valve sleeve 5 to be fixed on the middle and lower part, hole of lighter fuselage 1 central valve seat as shown in FIG., play valve body 3 effects such as spacing grade, between the lower surface of the upper surface of valve sleeve 5 and 3 thick 3-2 of valve body, lay cushion rubber 4, it can be the sealing ring that rubber plastic etc. is made, seal, under the effect of spring 2, cushion rubber 4 is compacted, stops the fuel gas that has entered fuselage 1 inside not from leaking here, also stops air from entering fuselage here.
Feature of the present invention just is, the thick axle 3-2 lower surface of the upper surface of valve sleeve 5 and valve body 3, no longer be all with the axial vertical plane that is parallel to each other, in the present embodiment, the lower surface of thick axle 3-2, be following little top big circular cone dignity, the upper surface of valve sleeve 5 is top little following big circular cone dignity, the section shape of these two taper seats at an angle, for example be the angle at acute angle or even right angle or obtuse angle,, realize sealing by these two taper seat compression cushion rubbers 4, experimental results show that, this structure is compared with prior art stronger sealing,, the stronger performance that prevents that fuel gas from releasing in the casing is arranged that is, this by changing into the mechanism by lower compression cushion rubber 4 on the acutangulate taper seat of this example with the prior art of the axially vertical flat compressed cushion rubber 4 that is parallel to each other, make sealing property obtain significant improvement.
Consult Fig. 2, Fig. 2 is a fuel gas by the key diagram of gas-flow closure of the present invention mechanism, when fuel gas tank A being shown attaching fuel gas in lighter with arrow among the figure is to move up, promoting valve body 3 moves up, filling channel is opened, gas is up along the gap between slide-bar 3-1 and the valve sleeve 5, two conical surface spaces of the thick axle 3-2 lower surface by valve sleeve 5 upper surfaces and valve body 3, pass through the valve base chamber space of thick axle 3-2 and fuselage 1 again, go upward to space, spring 2 place, because gas is pressed gas, be advanced into the fuel gas apotheca in the casing on can continuing, after waiting to fill it up with, fuel gas tank A moves apart valve body 3, the elastic force of spring 2 presses down valve body 3 again, makes two conical surfaces and cushion rubber 4 realize sealing together, prevents that the fuel gas in the upper casing from releasing.
In the present embodiment, adopt taper seat compression cushion rubber 4 up and down to realize sealing, the size of cushion rubber 4 and elastic force and material all will be matched suitably, and this point is easy to accomplish routinely.Taper seat angulation α can precedent spend the angle acute angles as 60 up and down, approximately is this angle shown in the cut away view among Fig. 2.According to the difference of the cushion rubber size that adopts, the number of degrees of taper seat angulation α can change up and down.
In addition, it is crooked also can to adopt the lower surface of the upper surface of valve sleeve 5 and 3 thick 3-2 of valve body to make, and groove shapes that cooperates cushion rubber 4 or the like is arranged, and also can realize than the better sealing effectiveness of prior art.
Enforcement of the present invention, the problem that fuel gas is leaked from lighter is well solved, and can obtain good economic benefit.
