Wait filter types.And vacuum filter has many advantages, such as that the rate of filtration is fast, simple to operation, is more and more applied.
The vacuum filter with miillpore filter is a kind of vacuum filter being most widely used in laboratory operation.It is real
The common vacuum apparatus in room is tested mainly by cup, cup lid, filtering liquid-collecting bottle, miillpore filter and attachment device structure on filter
Into.And micro-pore-film filtration refers to that using pressure be motive force, by the selectivity of film, by component of different sizes in blending ingredients
The technical method detached.The vacuum apparatus applied at present is varied, but is respectively provided with the advantages of simple and quick, so
Using increasingly wider.Existing vacuum filter miillpore filter used when being filtered operation is round filter membrane, therefore vacuum
The coupling part of filter is both designed as circle.But the effective filtration area of this filter membrane does not maximize the use,
So as to cause the waste of effective filter space.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of vacuum filter, the vacuum
The upper opening of filter setting neck is square, can increase the area flowed down for liquid in the case where width is constant, carry
High efficiency, and the duration that liquid is kept to flow so that filter process is stablized.
The utility model is realized using following technical scheme：A kind of vacuum filter, including upper cup lid, upper cup, connector,
Filter and receiving flask；The upper cup lid is covered on the opening of cup；The upper cup includes the neck below cavity portion and cavity portion；
The upper opening of the neck is square, and is opened in cavity portion；The under shed of the neck is connected with connector；In the cavity portion
Equipped with filter mounting table；The upper surface of the filter mounting table, which is equipped with to be open on from filter mounting table edge to neck, prolongs
The diversion trench stretched；The filter is placed on filter mounting table, and the upper opening of neck is completely covered；The filter is placed
Stepped changeover portion is additionally provided with above platform；The receiving flask is connected to the lower section of connector；The connector, which is equipped with, to be taken out
Vacuum interface.
Further, the upper cup lid is equipped with the convex edge for extending downwardly and coating cup edge.
Further, the cross section of the upper cup is square.
Further, it is additionally provided with flow-guiding mouth on the upper cup.
Further, the filter is at least two miillpore filters, and at least two miillpore filter is superimposed.
Further, the cross section of the receiving flask is circle.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is by being square by the upper limited opening of neck, in the case where diameter is constant, Neng Gouzeng
The big area flowed down for liquid, filter efficiency improve more than 20%；
2nd, the utility model by changeover portion diverted liquid and extends liquid flow distance so that liquid is in all directions
Filter is flow to, improves the efficiency of filtering.

Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further：
With reference to Fig. 1 and with reference to Fig. 2, a kind of vacuum filter including upper cup lid 1, upper cup 2, connector 3, filter 4 and is received
Collect bottle 5；Upper cup lid 1 is covered at the opening 21 of cup 2；Upper cup 2 includes the neck 23 of 22 lower section of cavity portion 22 and cavity portion；Neck 23
Upper opening 231 be square, and be opened in cavity portion 22；The under shed 232 of neck 23 is connected with connector 3；It is set in cavity portion 22
There is filter mounting table 221；The upper surface of filter mounting table 221 is equipped on from 221 edge of filter mounting table to neck 23
Be open the diversion trench 2211 extended；Filter 4 is placed on filter mounting table 221, and the upper opening of neck 23 is completely covered
231；The top of filter mounting table 221 is additionally provided with stepped changeover portion 24；Receiving flask 5 is connected to the lower section of connector 3；Even
Fitting 3 is equipped with and vacuumizes interface 31.
As preferred embodiment, upper cup lid 1 is equipped with the convex edge 11 for extending downwardly and coating 2 edge of cup.Upper cup lid 1
For being covered on upper cup 2, prevent liquid splash from losing and prevent foreign object from falling into cup 2 to pollute, and in the cladding of convex edge 11
Cup 2 is so that covering is complete.
As preferred embodiment, the cross section of upper cup 2 is square.
As preferred embodiment, flow-guiding mouth (not shown) is additionally provided on upper cup 2, plays and draws in pouring liquid
The effect of stream.
As preferred embodiment, filter 4 is at least two miillpore filters, and at least two miillpore filters are superimposed.
As preferred embodiment, the cross section of receiving flask 5 is circle.
Connect in use, interface 31 will be vacuumized with vacuum pump；Then liquid to be filtered is packed into the cavity portion of upper cup 2
22, cup lid 1 is covered, opens vacuum pump, then the liquid of cavity portion 22 is by suction, from each after 24 dispersing liquid of changeover portion
A direction falls into filter 4, then flows into diversion trench 2211, is drained to neck 23 through diversion trench 2211, is most flowed afterwards through connector 3
To receiving flask 5；Since the upper opening 231 of neck 23 is square, compared with the circle of the prior art, in the case that diameter is constant
The area of 23 plane of the opening of neck can be increased, more efficient under liquid flow, changeover portion 24 has in the horizontal direction by liquid
The effect of body shunting so that filter 4 is whole to play the role of transition, and diversion trench 2211 is played filter every rising and draw
The effect of stream keeps the gap between filter 4 and filter mounting table 221 so that liquid smoothly flows down.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
