Specific embodiment:
The utility model water is gentle comes in and goes out from same outlet, and the good airproof performance after inflation is easy to use.
Working process of the present utility model is: first, empty bottle filling liquid, note not filling, filling liquid amount (V liquid), according to empty bottle volume (V bottle)), filling inflation pressure (P0) and finally spray the complete pressure that should keep (P1) calculate, V liquid=V bottle × (1-P1 ∕ P0); After having filled with, lower cover is threaded connection at bottleneck, screws; Piston rod is movable back and forth in piston rod cavity, piston rod something or somebody to fall back on portion one side is provided with two piston rod grooves, be used for putting O type circle, ensure the sealing of piston rod cavity, the outer spring of surface cover of piston, spring is placed in spring card slot, and piston rod bottom fills a piston rod pressing plate,, on piston rod spring is fixed by screw tightening.Like this, press piston rod pressing plate place, piston rod head side is constantly stretched out piston rod cavity, until the O type circle in two piston rod grooves also stretches out piston rod cavity, piston rod cavity is in opening state, now spring is in compressive state, unclamp the pressure of piston rod pressing plate, piston rod is pulled back under the effect of spring, and the O type circle in two piston rod grooves is also got back to piston rod cavity, until piston rod head is stuck, piston rod cavity is in closed state.The apical head of lower cover has a lower cover groove, and for putting O type circle, above upper cover is tightened on lower cover time, this O type circle is pressed on the sidewall step of upper cover, and the leak tightness connecting for being placed on lower cover on ensureing, is threaded connection between upper and lower covers.
The button spindle middle part of upper cover is fluted, put O type circle, the button passage that is used for ensureing upper cover is in closed state, button bottom is connected with button spindle portion by draw-in groove, prevent that button spindle from skidding off button passage, simultaneously, in upper cover cavity, there is sidewall step, it is than slightly projection of upper cover sidewall, when upper cover is tightened in guarantee, the groove of lower cap header and O type circle press seal state, press the button, button push piston bar skids off until seal ring skids off piston rod cavity, under gas pressure, water from piston rod and piston rod cavity gap out, the side groove of piston rod has strengthened clearance space, ensuring enough water yields flows out.Now, between upper and lower covers, seal, upper cover button cavity also seals, and water can only be from outlet ejection.
When inflation, gas filled device is to piston rod platen pressure, all pushing piston-rod passage, then aeratings of two seal rings of piston rod groove (O shape circle); Add after gas, remove piston rod platen pressure, piston rod gos up under spring force and the effect of bottle internal gas pressure, and seal ring is got back in piston rod cavity, reaches sealing state; Upper cover, upper cover inside cavity has negative thread, with the head that is fixed on lower cover, button is as Fig. 5, in the middle of its button spindle portion, there is push-button recess, be used for putting O type circle, then put into button passage, O type circle is combined with passage closely, reach sealing state, then button spindle portion (by screw or buckle mode) is loaded onto in button bottom, ensure that button is under active state, its O type circle, all the time in button cavity inside, keeps sealing state.Press button (as do not taken on water pipe outside lower cover rod end chamber road, when use, bottleneck down, just energy contact piston bar cavity of water like this, do not take on water pipe and be mainly automated production conveniently), water under pressure liquid will the out arrival upper cover cavity on piston rod in, because seal between upper and lower covers, button passage is also in sealing state, and water can only be from outlet ejection; Release button, the piston rod of lower cover is got back to rod end chamber road class under spring force and bottle internal gas pressure effect, and lower cover is again in sealing state, and button jack-up.
The utility model is taked double-canopy structure (upper and lower cover), and upper and lower covers is separable.Lower cover can meet the operations such as the filling spiral cover inflation of automation, and ensure the good sealing property of bottle in storage and transport process, upper cover ensures not produce leakage under use state, and, when use, can stop at any time, still can keep the pressure state in bottle, upper and lower covers can separate at any time, an inflating pressure, repeatedly uses; (2) the Double seal ring structure on piston rod, ensures better tightness; (3) groove of piston rod side (4-3) is that piston rod has air inlet and water exit, and does not need air inlet and water outlet two nested structures in order to ensure that liquid can flow out more smoothly.Total is simply small and exquisite, reliably effective.
The utility model lower cover is consistent with conventional bottle cap profile, and filling, the spiral cover of available common carbonated drink, aerating automatic production line are produced together with bottle.Upper cover is produced separately, uses and is just combined in one, and can separate at any time.With low cost, can be mass-produced, transport stores and uses all very convenient.
More than by preferred and description that specific embodiment is detailed the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within groundwork of the present utility model; any amendment of doing, combine and be equal to replacement etc., within being all included in protection domain of the present utility model.
