The end face of dress flange is against on some support rods, and the circular inserted sheet interference fit is plugged in the inwall of lower dropping funnel；Under described
What the matching of dropping funnel and circular inserted sheet was docked one is truncated into columnar structured, and remainder is circular platform type structure；The bottom of the lower dropping funnel
Portion is provided with downcomer；Bubble filter membrane is provided with lower dropping funnel.
The stomata matching is wherein in a support rod.
The height of the upper dropping funnel is the 2/3 of the height of lower dropping funnel.
Accommodation space is together form between the mounting flange top surface, annular groove, adjacent two support rods.
What the present invention can reach has the technical effect that：
Compared with prior art, integrated-type dropping funnel of the invention, the function of modeling pin, dropping funnel and bubble filter is integrated with, is made
Obtaining the overall manufacturing cost of transfusion device reduces；
Compared with prior art, integrated-type dropping funnel of the invention, stomata matched design is wherein in a support rod, Neng Goubao
The diameter dimension of card stomata is enough to realize into outlet；
Compared with prior art, integrated-type dropping funnel of the invention, support rod is provided with annular groove, so as to ensure that installation
The bulk strength of bulge loop, in addition, in processing, additionally it is possible to reduce the processing dimension of installation bulge loop, reduce production cost；
Compared with prior art, integrated-type dropping funnel of the invention, fastening is realized by being interference fitted between upper dropping funnel and lower dropping funnel,
Install it is more convenient, can also spreading glue therebetween, make its connection more firm.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 is the sectional view of integrated-type dropping funnel of the present invention；
Fig. 2 is the sectional view of the upper dropping funnel of the present invention；
Fig. 3 is the sectional view of the lower dropping funnel of the present invention.
