This metering seat 1 periphery is arranged with a spring 13, and control ring 5 is to be sheathed on outside the metering seat 1, these spring 13 two ends are replaced with pressure head 2 and control ring 5 respectively, so that the pressure head usefulness that 2 pressurizeds reset to be provided, and be provided with a runner 25 that communicates with metric space 11 in this pressure head 2, and should go up valve group 3 are runner 25 places that are located in the pressure head 2, as Fig. 1, shown in Figure 3, this control ring 5 is to be plate-like, and these spring 13 1 ends are butted on control ring 5 ends, and the other end is butted on cap rib 23 ends, so that the pressure head effectiveness that 2 pressurizeds reset to be provided, just is positioned on runner 25 paths of pressure head 2 and should go up valve group 3;

Valve group 4 respectively was provided with an outer shroud 31 under upward valve group 3 reached, ring 32 in 41 and one, 42, this outer shroud 31 wherein, be provided with one in 41 and support ball 311,411, should support ball 311,411 peripheries are with several ribs 312,412 with outer shroud 31,41 inwalls connect, and should interiorly encircle 32, the 42nd, be placed in the outer shroud, and interior ring 32,42 central authorities have provided one to lead 321,421, should support ball 311, the 411st, support into leading 321,421 ends are with confined bed road 321,421, as Fig. 1, shown in Figure 3, should support ball 311,411 peripheries equidistantly are provided with three and outer shroud 31, the rib 312 that 41 inwall one connect, 412, borrow this rib 312,412 make to ball 311,411 are positioned outer shroud 31,41 central authorities also support into interior ring 32,42 lead 321,421 ends, and support ball 311,411 force-applied leaving slightly lead 321,421, and rib 312,412 provide to ball 311, the 411 confined bed roads 321 that reset, 421 elastic force;

In addition, as Fig. 1, shown in Figure 3, should support ball the 311, the 411st, semicircular in shape, and its semicircle partly is to going into to lead in 321,421, and this leads the 321, the 421st, by with support the past the other end of an end that ball 311,411 contact and be tapered diameter, and lead 321,421 peripheries and be the rounding shape, borrow this rounding to sentence and prevent to sustain damage to ball 311,411 in diameter the widest position;

As Fig. 3, shown in Figure 4, when pushing pressure head 2, plug sleeve 21 is that the air in the extruding metric space 11 are pushed leaving to ball 311 of valve group 3 open and led, and flow out extraneous by runner 25, and the ball 411 that supports of following valve group 4 is pushed against confined bed road 421 by air, in view of the above when pressure head 2 resets, metric space 11 reverts to the volume flow rate when not being subjected to plug sleeve 21 extruding, thereby downwards valve group 4 produces suction and makes to leave to ball 411 and lead 421, allow the interior liquid of bottle flow in the metric spaces 11 through leading 421, the ball 311 that supports of valve group 3 is subjected to suction and confined bed road 321 on this moment, then pushing pressure head 2 again can make the liquid in the metric space 11 flow out outside the runner 25, the liquid of drawing again when pressure head 2 resets again in the bottle enters in the metric space 11, and the effectiveness of quantitatively drawing is provided in view of the above;

These control ring 5 inner faces are provided with one and support rib 51, and this metering seat 1 outer circumferential face is provided with the straight trough 52 identical with control ring 5 axial directions together, and several and straight trough 52 joins and the translot 53 of different heights, as Fig. 1, Fig. 4, shown in Figure 5, what these control ring 5 inner faces were provided with this bulk supports rib 51, the straight trough 52 of this vertical configuration reaches and several translots 53 of straight trough 52 vertical connections and metering seat 1 periphery is provided with, and control ring 5 is provided with an index 54, this index 54 is to point to support rib 51, and in these several translots 53 direction of offering of at least one translot 53 and other translot 53 opposite (present embodiment is three translots 53, one of them translot 53 and other two translots 53 to offer direction different), and make the sense of rotation of control ring 5 on this translot 53 different with other translot 53;

Spin Control ring 5 can make to rib 51 in straight trough 52 enters the translot 53 of different heights, and adjust the distance of 2 of control ring 5 and pressure heads according to this, the operating range that makes pressure head 2 can measure seat 1 relatively is controlled, but and change the volume of metric space 11 storaging liquids, when the distance of pressure head 2 relative control rings 5 is far away, the distance that pressure head 2 compressible spring 13 are measured seat 1 activity relatively is longer, allow plug sleeve 21 can more enter in the metric space 11, thereby can enter in the metric space 11 temporary by flowing out more liquid in the bottle, and during the close together of pressure head 2 relative control rings 5, it is shorter that pressure head 2 compressible spring 13 are measured the distance of seat 1 activity relatively, the distance that allows plug sleeve 21 enter in the metric space 11 is limited, the liquid that makes metric space 11 to keep in relatively is less, provide the user to set the effectiveness of flow whereby, and can not waste dosage or need repeatedly push pressure head 2 to draw required dosage with control ring 5.

See also shown in Figure 6ly, it is other embodiment of the delicate metering pump structure of the utility model vacuum flask, and wherein primary clustering is identical with first embodiment, does not repeat them here, and followingly only narrates it with regard to different structure.

Second embodiment as shown in Figure 6, these pressure head 2 peripheries are provided with an outward extending wing ring 26, and spring 13 two ends are replaced with wing ring 26 and control ring 5 respectively.
