As shown in fig. 11 and 12, the aerosol valve of the prior art includes a fixed cap 3 'fixedly connected with the bottle body, a valve chamber member 4' disposed inside the fixed cap 3 ', a quantitative chamber member disposed inside the valve chamber member 4', and a valve rod 5 'sequentially passing through the fixed cap 3', the valve chamber member 4 'and the quantitative chamber member 6' (some prior art aerosol valves have no quantitative chamber member, so the valve rod 5 'may only pass through the fixed cap 3' and the valve chamber member 4 '), and a gasket 101' is disposed between the valve chamber member 4 'and the fixed cap 3'. The valve rod 5 ' is pressed down in the inflating process in the production link, the lower end of the valve rod 5 ' is still in sealing connection with the valve chamber component 4 ', the gasket 101 ' can only be forcibly squeezed to inflate in the inflating process, the gasket 101 ' is prone to displacement or damage, slow leakage and the like are caused, and the structure has the problems of high rejection rate, low production efficiency and the like. Chinese utility model patent with publication number CN214320605U discloses an extra large spraying quantity quantitative aerosol valve, and its technical scheme who adopts is that valve chamber spare 46 is cavity and lower extreme confined cylindricality structure, is equipped with the annular thin slice 64 that stretches into in interior passageway 62 on the edge of interior mouth 63, and the lower extreme of valve rod 54 passes interior mouth 63 and inserts in interior passageway 62, and is equipped with the slope that realizes sealing with annular thin slice 64 interference fit on the lower extreme of valve rod 54. Because the terminal surface of valve rod 5 is straight rod-shaped, no matter be static state, filling state or open mode, valve rod 5 all with annular thin slice 64 valve chest piece 4 interference fit or tight fit, lead to exist at the inflation in-process and aerify slowly, the packing ring because of pressure takes place displacement scheduling problem. Then like the chinese utility model patent of publication No. CN213535884U, disclose a novel ration valve, the technical scheme that its adopted is that the upper and lower both sides of ration bowl are provided with interior packing ring 101 one and interior packing ring 101 two respectively, and interior packing ring 101 one and interior packing ring 101 two all with valve rod 5 interference fit, because the terminal surface of valve rod 5 is straight shaft-like, no matter be quiescent condition, filling state or open state, valve rod 5 all with interior packing ring 101 interference fit or tight fit, lead to inflating slow in the inflation process, the packing ring takes place the displacement scheduling problem because of pressure.
In addition, there is also a conventional method of inflating a gas mist valve, in which a gasket is provided between a valve housing member 4 'and a valve stem 5', and the gasket is forcibly pressed to inflate the gas mist valve during inflation, which also tends to cause displacement or damage of the gasket, resulting in slow leakage, and the like.
