Abstract
The utility model discloses a kind of drainage funnels, including contain liquid umbrella, filler neck, fistulae, confluence mouth, confluence piece and drainage tongue；It contains liquid umbrella lower end to be connected with the upper end of filler neck, filler neck lower end is connected with the upper end of fistulae；The lower end inner wall of fistulae is connected with the upper end of confluence piece；The oblique lower end of confluence piece is connected with the top of drainage tongue；Fistulae outer wall is equipped with confluence mouth.The utility model structure is simple, fashionable, when volumetric flask constant volume, avoids constant volume liquid outflow and is stained with the phenomenon that constant volume graduation mark or more causes constant volume error and brings great convenience for laboratory technician, use is conveniently, safely quick, suitable for being widely popularized.
Description
Technical field
The utility model belongs to experimental instrument technology, and in particular to a kind of drainage funnel.
Background technique
Drainage instrument used in current experiment room only has glass bar, and when volumetric flask constant volume, needing will be by constant volume
Liquid be transferred in volumetric flask, the process can use glass bar drainage, operate comparatively relatively difficult, accidentally
It will will be transferred liquid to be spread to outside volumetric flask, or even be stained on the inner wall of volumetric flask constant volume graduation mark or more, and cause constant volume
Error, not enough precisely.
Summary of the invention
Shortcomings and deficiencies present in view of the above technology, purpose of the utility model is to solve the above problems, mention
For a kind of drainage funnel, special feature is that the liquid of the lower end outflow of drainage funnel will not be stained with container inner wall, down-flowing liquid
The center of container inner wall can be always held at.
Realizing technical solution used by above-mentioned purpose of utility model is: providing a kind of drainage funnel, including contains liquid umbrella, leakage
Struggle against neck, fistulae, confluence mouth, confluence piece and drainage tongue；The Sheng liquid umbrella lower end is connected with the upper end of filler neck, the filler neck
Lower end is connected with the upper end of fistulae；The lower end inner wall of the fistulae is connected with the upper end of confluence piece；The oblique of piece that converge
It is connected to lower end with the top of drainage tongue；The fistulae outer wall is equipped with confluence mouth.
Further, the filler neck outer wall is equipped at intervals with groove, and the groove is at least provided with one.
Further, the confluence piece is at least provided with three pieces.
Further, the Sheng liquid umbrella, filler neck, fistulae, confluence mouth, confluence piece and drainage tongue use glass material.
The utility model structure is simple, fashionable, when volumetric flask constant volume, avoids constant volume liquid outflow and is stained with
The phenomenon that causing constant volume error more than to constant volume graduation mark brings great convenience for laboratory technician, and use is conveniently, safely quick,
Suitable for being widely popularized.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of drainage funnel of the utility model.
Fig. 2 is a kind of present invention looks up structural representation of drainage funnel of the utility model.
In figure: 1., which contain 2. filler neck of liquid umbrella, 201. groove, the 3. fistulae 4. confluence confluence piece 6. of mouth 5., drains tongue.
Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model work is further retouched below with reference to embodiment
It states.
A kind of drainage funnel according to shown in Fig. 1-2, including contain liquid umbrella 1, filler neck 2, fistulae 3, confluence mouth 4, confluence piece 5
With drainage tongue 6；It contains 1 lower end of liquid umbrella to be connected with the upper end of filler neck 2,2 lower end of filler neck is connected with the upper end of fistulae 3；Leakage
The lower end inner wall of pipe 3 is connected with the upper end of confluence piece 5, and the piece 5 that converges is at least provided with three pieces；Converge piece 5 oblique lower end with draw
The top of stream tongue 6 is connected；Confluence mouth 4 is equipped with outside fistulae 3, for by the outlet Shi Xiangzhong by the liquid of constant volume through fistulae 3
The heart concentrates convergence, generates the centripetal force of an ecto-entad；2 outer wall of filler neck is equipped at intervals with groove 201, and groove 201 is at least set
There is one, for balancing measuring bottle inner and outer air pressure；Preferably, there are four groove 201 is set.
Article can be tested not according to using by containing liquid umbrella 1, filler neck 2, fistulae 3, confluence mouth 4, confluence piece 5 and drainage tongue 6
Together, using corresponding making material, it is preferred that use glass material.
In use, the utility model can be inserted into the measuring bottle for needing to shift solution by user, make filler neck 2 embedded in measuring bottle
Then bottleneck holds another measuring bottle equipped with solution and pours into along liquid umbrella 1 is contained, solution along filler neck 2, fistulae 3 and converges at this time
Stem bar 4 enters transfer measuring bottle and concentrates and converge to center through confluence mouth 4 when liquid enters transfer measuring bottle through the outlet of fistulae 3, produces
The centripetal force of a raw ecto-entad, then flows into transfer amount bottle under the drainage of drainage tongue 6；To inside measuring bottle due to molten
When the overfilled air pressure inside of liquid rises, inside and outside air pressure balance displacement can be carried out by the groove 201 being arranged on filler neck 2；To
When solution is left a little, less solution converges in center through confluence piece 5 along 3 lower part of fistulae, then along the drainage at center
Tongue 6 flows into transfer measuring bottle, maximumlly displaced solution.
The utility model structure is simple, fashionable, when volumetric flask constant volume, avoids constant volume liquid outflow and is stained with
The phenomenon that causing constant volume error more than to constant volume graduation mark brings great convenience for laboratory technician, and use is conveniently, safely quick,
Suitable for being widely popularized.
The above, the only preferred embodiment of the utility model cannot limit the utility model practical range with this；It is all
According to simple equivalent changes and modifications made by present utility model application the scope of the patents and creation description, this should still belong to
In the range of utility model patent is covered.
