Portion is removably connected with volumetric bottle 3, is connected here using thread seal.The bottom of liquid holding bottle 1 is provided with the first check valve 11
For being connected to liquid holding bottle 1 and volumetric bottle 3, it is volumetric bottle 3 to the of reaction vessel 9 that the bottom surface of volumetric bottle 3, which is provided with conducting direction,
Two check valves 31 are arranged at the inner concave, which is also the liquid outlet of volumetric bottle 3, in order to enable volumetric bottle 3
Interior liquid outflow is more thorough, the interior bottom of volumetric bottle 3 can be also provided with into interior concave spherical surface, and second one-way valve 31 is set
Set the lowest part in the interior concave spherical surface.
It is provided with pressing mechanism on the bottle cap 2 of liquid holding bottle 1, for liquid to be pressed to volumetric bottle 3 from liquid holding bottle 1, is squeezed
Mechanism includes air bag 5, and is provided with the conducting direction external world to the 5th check valve 51 inside air bag 5, to work as on air bag 5
Air pressure when extruding gasbag 5 in liquid holding bottle 1 increases, and liquid presses to volumetric bottle 3 by the first check valve 11, when release air bag
After 5, air bag 5 will be restored by the deformability of itself and the air in the external world passes through the 5th check valve 51 and fills into air bag 5.And
The liquid for entering volumetric bottle 3 increases the air pressure of volumetric bottle 3, excludes not in time if this increases air pressure, and it is fixed to enter
Liquid in measuring bottle 3 will be directly discharged by second one-way valve 31, the effect of quantitative measurement is unable to reach, so in volumetric bottle 3
On be also combined with degassing extruder structure, it is convenient when liquid enters volumetric bottle 3 and the air pressure in volumetric bottle 3 is caused to become larger, it is more
Residual air body can be discharged in time by exhaust gear.And enter the liquid in volumetric bottle 3 then can by observation scale and
The amplitude of hand pinching air bag 5 controls.
Reaction vessel 9 therein referring to attached drawing 1-3, its oral area be provided with docked with volumetric bottle 3 to interface 92, can be with
Connection between the two is realized in such a way that screw thread is screwed on, and is arranged in the side wall of reaction vessel 9 close to the position of oral area
There is gas outlet 91, in order to which gas after reaction liquid enters reaction vessel or during the reaction is from the gas outlet
Discharge, when needing to use detection reaction gas, equipment which can connect detection gas.
Degassing extruder structure therein is referring to attached drawing 4-6, the shell 4 including 3 wall surface of volumetric bottle is arranged in, shell 4 it is interior
Part is extruding cavity 41 and discharge chamber 42, and the cross sectional shape of extruding cavity 41 and discharge chamber 42 therein is round and discharge chamber 42
Section radius be greater than extruding cavity 41 section radius, in discharge chamber 42 sliding be connected with sealing element 6, sealing element 6 is sliding
The extreme position of left and right two extruding cavity 41 and gas port 32 can be formed sealing, certainly here in sealing element 6 and volumetric bottle 3
It is provided with corrugated rubber pipe 7 between wall surface, when sealing element 6 is drawn close to gas port 32, can first press corrugated rubber pipe 7
Contracting, is then worked by sealing element 6 and corrugated rubber pipe 7 and forms sealing between gas port 32.It should be understood that can also be with
It is not provided with corrugated rubber pipe 7, forms sealing between the mode and gas port 32 of 3 wall surface of volumetric bottle that directly reclined by sealing element 6.When
When sealing element 6 and extruding cavity 41 are drawn close, pass through first row stomata 421, second row stomata 71 and air guide between extraneous and volumetric bottle 3
Hole 32 is connected to, and when liquid enters volumetric bottle 3 from liquid holding bottle 1, it is fixed that extra air will be discharged by this exhaust gear
Measuring bottle 3, the problem of preventing high pressure from directly squeezing out liquid out of volumetric bottle 3.
Sliding is connected with inflator 8 in extruding cavity 41, and one end of inflator 8 is directly fixed with sealing element 6, is internally provided with work
Plug 81, piston rod is then reversely pierced by 41 formation operation bar 82 of extruding cavity, is provided with air guide direction on piston to be extraneous to inflator 8

And the conducting atmospheric pressure of third check valve 61 is greater than the deformation power of the elastic component.Thus when squeezing into predetermined amount in volumetric bottle 3
Liquid after, can first push operating stick 82, inflator 8 will be moved with sealing element 6 to gas port 32 and by ripple at this time
Sealing (or sealing is directly formed between gas port 32 by sealing element 6) is formed between the compression of rubber tube 7 and gas port 32, after
After continuous promotion operating stick 82, the gas in inflator 8 is pressed to third check valve 61 and makes its unlatching by piston 81, and gas will pass through
Gas port 32 is pressed into volumetric bottle 3, and the air pressure in volumetric bottle 3 increases the liquid in it will be discharged to instead by second one-way valve 31
It answers in container 9.It is once all projected insufficient for the liquid in volumetric bottle 3 if pushing, pullback operation bar 82, at this time gas
It will be filled in inflator 8 by the 4th check valve 811 until piston 81 encounters the bottom of inflator 8, and draw catch bar, inflator 8 again at this time
It retracts and retracts with sealing element 6 along discharge chamber 42, form negative pressure in volumetric bottle 3, since gas has good expansion
Compressibility, it is extraneous until the position that sealing element 6 return back to first row stomata 421, second row stomata 71 is connected to gas port 32
Air will be directly added into volumetric bottle 3, then push operating stick 82 again, repeat above-mentioned extrusion step, until by volumetric bottle 3
Interior liquid all squeezes out.
Two dosing containers of the operation setting above reaction vessel 9 in the same way, may be implemented to measure quantitative
The reaction liquid and then quantitative reaction liquid is discharged into reaction vessel reacts, and realizes quantitative reaction experiment, real
The variable tested can be precisely controlled, is easy to use, simply.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
