Detailed description of the invention
Key concept of the present invention as shown in Figure 1 and Figure 2, it is made up of the jacking mechanism 3 of the tubulose valve pocket 1 be located at bottom lighter gas box, rubber seal post 2, rubber seal post: the tubulose valve pocket 1 bottom lighter gas box is the garden through hole of a reducing, be communicated with the inside and outside of gas box, reducing round tube hole 1 be divided into 11,12 two sections of intervals, epimere 11 aperture is large, and hypomere 12 aperture is little; Rubber seal post 2 is located in the chamber of tubulose valve pocket epimere 11; The top of round tube hole 1 is provided with the jacking mechanism 3 of rubber seal post, presses closer one end 21 of rubber seal post 3, makes the effective sealing of the garden anchor ring 15 of the paired valve pocket hypomere 12 of the other end 22 garden planar shaped of rubber seal post 2.
As Fig. 1, Fig. 2, shown in Fig. 3, we further can be provided with one or more than one air guide groove 14 at tubulose valve pocket epimere 11 along through hole direction, in Fig. 1 and Fig. 2, due to the angle difference 90 degree of section, so groove 14 position is in the drawings also different with distribution, as being provided with groove 14, we are adding in the process of combustion gas to lighter, combustion gas just can be very unobstructed pass through from air guide groove 14, certainly we also can not arrange air guide groove 14, but when adding combustion gas, combustion gas can only be passed through from the thin crack between the inner peripheral surface of the epimere 11 of the garden outer peripheral face of rubber seal post 2 and tubulose valve pocket 1, patency will be subject to the impact of the fit clearance size of the epimere 11 of rubber seal post 2 and tubulose valve pocket 1, the too little aerating in gap is just very slow, the gap of aerating is even blocked completely due to swelling in combustion gas of rubber seal post 2, if gap is too large, the perpendicularity of rubber seal post 2 in tubulose valve pocket epimere 11 just can not ensure, thus have influence on the reliability sealed between 22 garden planes and garden anchor ring 15.
As shown in Figure 3, we the reducing garden through hole hypomere 12 of tubulose valve pocket 1 bottom lighter gas box can be provided with through hole extension 13, the through hole internal diameter of extension 13 is greater than the through hole internal diameter of hypomere 12, and at through hole 13, the change junction of 12 size internal diameters is provided with the inclined-plane 16 seamlessly transitted, the benefit of such setting after gas box has welded, can load rubber seal post 2 easily again from this head of extension 13, rubber seal post 2 is by exerting pressure by the radial direction on inclined-plane 16 under the effect of outside pressure, diameter progressively diminishes by the hypomere 12 of reducing garden through hole 1, enter into epimere 11, rubber seal post 2 diameter restores to the original state, back-off is formed with garden anchor ring 15, and this load be along cant to, load than being easier to, withdrawing is hair down direction, form buckle.If adopt compressed spring type jacking mechanism also can load stage clip 3 from this head of extension 13, reinstall rubber seal post 2, see Fig. 6, the same buckle formed between rubber seal post 2 and garden anchor ring 15.Reinstall rubber seal post 2, stage clip 3 after gas box has welded, huge energy when welding can be avoided the infringement of rubber seal post 2 and tubulose valve pocket 1, the reliability of sealing can be improve, the assembly technology of lighter also advantages of simple more; Certainly in order to the succinct of structure also can not adopt this scheme.
As shown in Figure 1, Figure 2, Figure 3 shows, we further can be set to sphere 21 rubber seal post 2 upper surface, the benefit that upper surface is set to sphere 21 to improve the retraction space of rubber seal post 2 when adding combustion gas, serve the effect of spring-like, be conducive to the unobstructed of aerating, certainly at rubber seal post 2 epimere, a round platform is set to replace sphere, also can serves the same role, see Fig. 4; It is also feasible that upper surface is set to garden plane, but the result of use of intake valve is just so not good, it is reasonable selection that lower surface 22 is set to garden plane, when can effectively prevent from pressing too large in gas box, rubber seal post 2 outwards comes off, also be conducive to the reliability of sealing between 22 Mian Yu garden anchor rings 15, it is also feasible that certain lower surface is set to sphere.
As shown in Figure 1, Figure 2, Figure 3 shows, we are further set to the thin bar 3 concentric with tubulose valve pocket the jacking mechanism of rubber seal post 2, its benefit is also to reserve larger retraction space to rubber seal post 2 when adding combustion gas, because the diameter of the thin bar 3 of the jacking mechanism of rubber seal post is much less than rubber seal post 2, so the space around thin bar 3 is under the exerting pressure of filling gas mouth, just can be converted into the retraction space of rubber seal post 2, arrange like this and aerating just can be made more unobstructed; In fact the same with tubulose valve pocket 1, the part of thin bar 3 also just on lighter gas box is same entirety with gas box shell, just due to it in the present invention the special role that rises and do explanation special a bit.
As shown in Figure 1, Figure 2, Figure 3 shows, we are further set to stage clip 3 the jacking mechanism of rubber seal post, see Fig. 6, its benefit can reserve huge retraction space to rubber seal post when adding combustion gas, make aerating more unobstructed, the feel of inflation is better, and the reliability of sealing is also better, certainly the production cost that a spring 3 can increase lighter is added, so both advantageous and disadvantageous.
As Fig. 4, Fig. 5, shown in Fig. 6, as everybody knows, the gas box of lighter is generally the hollow structure by ultrasonic bonding, several plastic part that is same or similar materials being welded together and formed, so the manufacture craft of gas box and structure have much a variety of, according to the different structure of lighter gas box, we contemplate such three different enforcement situations, certainly can also change and other structure a lot, but be consistent with the concept of the intake valve of invention, in these three embodiments, plastic part 51 is according to different needs with 52, the position of welding is different.Through hole 55 shown in Fig. 5 is the special constructions according to gas box, the scheme of a connection gas box inside of taking and the tubulose valve pocket 1 of charge valve.
