In the micro-sprayer field, passage is to guarantee sprayer make-up gas in the course of the work, and the container external and internal pressure keeps the effect of balance.This invention is changed into passage in the middle part of the epimere of the pump housing, is in the centre position of piston 9 after the installation, and the upper space of liquid and piston 9 is formed at interval, and liquid can not enter into the piston upper space by passage.
By above-mentioned improvement make micro-sprayer vibrations appear in can or transportation, when being inverted, liquid that can not produces the cooperation place phenomenon of leakage of valve rod 4 and interior plug 5 in the bottle.Scheme one is that passage 16 is offered at the epimere middle part of the pump housing 14, makes it at the piston middle part, and piston is enclosed in inside to passage, makes the above position of pump housing internal piston realize good sealing effectiveness in can or transportation.Scheme two is that the exhaust position with sprayer changes and is located on the valve rod 4, rise is from being h (Fig. 9), gas passes through air discharge duct 18 adding container internal gas pressures when pressing down spraying, but this improvement need ask sprayer when being shaken, and air discharge duct 18 positions on the valve rod 4 can not enter into pump housing inside.Therefore, the distance of h will be restricted, otherwise will leakage, and the stroke that moves up and down that just valve rod produces under being shaken can not be too big.The groundwork principle of another kind of scheme produces a layer sealing surface between soft plastic 17 and Nei Sai 5 contact-making surfaces, prevent that bottle interior liquid from entering in the pump housing 14 by passage 16, and the gap of stopping soft plastic 17 and Nei Sai 5 generations causes liquid to spill.Described soft plastic 17 is an one with valve rod 4.Involved sprayer part name and the title of other enterprise's name then are as the criterion with the enterprises name if any different among the present invention.
By above-mentioned design, improved original micro-sprayer hermetically-sealed construction, make sprayer inner sealing performance reach good level, and spray volume is big, lift is higher, to the concentration no requirement (NR) of liquid.Technical have an obvious improvement, stops micro-sprayer and produce leakage and odoriferous phenomenon in transportation or filling liquid process, thereby improve the product specification of micro-sprayer.
