The operation principle of this allotter is as follows: glass bead places the pipette tip in the pump housing, and with the spherical cavity inclined-plane 201 of spherical cavity lower end in the pump housing at clearance fit seal, and fixed by the spherical cavity limit rib 202 of muscle position, spherical cavity upper end, thus control the glass bead active strokes distance in spherical cavity；Spring is arranged on valve rod and is connected in the chamber between seat, and the upper end of spring is fixed at the spring groove 801 of valve rod, and lower end is fixed on and is connected the inner ring muscle 601 of rod aperture 602 on seat；Linking closely with pin catching groove 802 plane of valve rod at bar catching groove 401 plane of needle, it is fixing to coordinate, prevent from making needle flick with valve rod and separating under the action of the spring, and be provided with and be easy to the rib groove that liquid passes through, coordinate with movable sealing at the spacer ring muscle 501 of piston at the annular groove 402 bottom needle；At the inside race 502 of piston with the mouth inner ring 803 of valve rod at clearance fit seal, when preventing from using, liquid is when needle is opened with piston seal position, in being flowed into the spring cavity being connected between seat and piston between valve rod with piston；Coordinate with cavity face movable sealing at the piston stroke chamber 203 of the pump housing at the outer stopper ring 503 of piston: after assembling product completes, piston, needle, the pump housing, glass bead form annular seal space.Pressure duckbilled, press under band ovable valve stem, needle, piston, and liquid constantly reduces and pressurized because of cavity in the cavity of annular seal space, now hoodle pressurized firmly seals with the pump housing, and piston in folding process with the interior wall friction of the pump housing, make piston upwards beat, and be opened with the sealing position coordinated between needle, piston upwards beat after still with valve handle activity fitted seal, so intracavity liquid outwards can only spray by flowing in valve rod between piston and needle and passing through duckbilled.After pressing hands under duckbilled, carry out rising by recoil of spring power and reset, now band ovable valve stem, needle, piston rise, and piston is by wall friction in the pump housing in uphill process so that it is beat downwards, and and needle between sealing position recompounding seal, the cavity of annular seal space forms negative pressure state because volume constantly increases, now glass bead is upwards beated and cannot be sealed with pump housing inclined-plane, so can only be by the cavity inhaled in the liquid in pipe suction pump housing and fill up with Balance Air pressure reduction, to reach water effect on the pump housing.When pressure duckbilled sprays liquid the most again down, and such iterative cycles liquid the most constantly tries spray.
Sealing under this allotter closed mode is as follows: after this allotter coordinates with fill bottle and tightens, liquid in preventing bottle need to be sealed at each cooperation flow out, it is illustrated in figure 1 the closed mode of this allotter, now press rotation under duckbilled, external screw thread circle 804 with ovable valve stem carries out threaded engagement with the female thread circle 602 being connected seat, and after tightening closedown, duckbilled is fixing cannot be depressed and resilience, spray cannot be tried, it is achieved closing function.Owing to closed mode duckbilled need to be pressed down, and drive the spacer ring muscle 501 of piston and annular groove 402 sealing position of needle to be in open mode, so now fitted seal at the outer ring muscle 403 of needle and the needle stroke chamber 204 of the pump housing, to prevent liquid suction passage from flowing into by piston, valve rod from the pump housing and to flow out from duckbilled；Connect seat outer convex rib 604 at, at buckle ring groove 605 respectively with the connection seat chamber 205 of the pump housing at, at seat buckle ring 206 use interference fit seal, from connecting outflow between seat and the pump housing after avoiding liquid to be entered by the pore 207 of the pump housing, at the same rod aperture 603 connecting seat with the stair ring muscle 805 of valve rod at interference fit seal, it is to avoid liquid flows out and contact spring between seat and valve rod from connecting after being entered by pump housing steam vent；At the inside race 502 of piston with the mouth inner ring 803 of valve rod at clearance fit seal, it is to avoid liquid flows out between piston and valve rod after being entered by pump housing steam vent.The most each fitted seal point must be simultaneously in sealing state, could realize pressing product integral sealing state after closedown under duckbilled, ensures after joining fill bottle abnormal without leakage.
In sum, the feature of this allotter is as follows: 1, spring position designs outside annular seal space, for external spring structure, product makes liquid directly not contact with spring during normal use, it is to avoid makes spring get rusty because of the formula components of liquid and spring materials chemically reactive and affects the outward appearance of spring, function and use the contamination and deterioration etc. of liquid abnormal；2, coordinate with movable sealing at the spacer ring muscle 501 of piston at the annular groove 402 of needle；At the inside race 502 of piston with the mouth inner ring 803 of valve rod at clearance fit seal, prevent liquid from flowing in spring cavity between valve rod and piston during use；When 3, pressing closedown under duckbilled, seal at the outer ring muscle 403 of needle and the needle stroke chamber 204 of the pump housing, prevent liquid from being flowed into and through piston, valve rod from duckbilled outflow by suction pipe from the pump housing；Connect at the rod aperture 603 of seat with the stair ring muscle 805 of valve rod at fitted seal；Liquid is avoided to flow out and contact spring between connection seat and valve rod after being entered by the pore of the pump housing；4, when duckbilled assembles with valve rod, elder generation is imported the interior muscle groove of the 806 of valve rod by the outer rib of duckbilled, the phenomenons such as the interior ring edge groove 807 of the interior buckle ring 1202 and valve rod that press to duckbilled again coordinates fixing, overlapping with valve rod muscle position when so can effectively solve to assemble duckbilled, to damage by pressure；5, fixing lid design can preferably improve product stability, the circle mouth muscle 1101 of i.e. fixing lid is buckled at the outer bead groove 606 connecting seat, the fit clearance between valve rod is reduced after assembling fixing lid, can effectively prevent from the related valve rod because duckbilled rocks from rocking to cause and the coordinating and the instability of seal point of each correlated parts, cause leakage, blow-by, easily the undesirable element such as get loose.
