Compared with prior art, the integrated-type dropping funnel of the utility model, a stomata matched design support rod wherein
It is interior, it can guarantee that the diameter dimension of stomata is enough to realize disengaging gas；
Compared with prior art, the integrated-type dropping funnel of the utility model is provided with support rod, to protect in a ring groove
The integral strength of installation bulge loop is demonstrate,proved, in addition, in processing, additionally it is possible to which the processing dimension for reducing installation bulge loop reduces production
Cost；
Compared with prior art, the integrated-type dropping funnel of the utility model passes through interference fit between upper dropping funnel and lower dropping funnel
Realize fastening, install it is more convenient, can also spreading glue therebetween, keep its connection stronger.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments:
Fig. 1 is the cross-sectional view of the utility model integrated-type dropping funnel；
Fig. 2 is the cross-sectional view of the upper dropping funnel of the utility model；
Fig. 3 is the cross-sectional view of the lower dropping funnel of the utility model.
Specific embodiment
It please refers to Fig.1 to Fig.3, the utility model provides a kind of integrated-type dropping funnel, including upper dropping funnel 1 and lower dropping funnel 2, described
The top of upper dropping funnel 1, which is integrally formed, is equipped with modeling needle 3, is equipped with the medical fluid runner 4 and gas flow 5 not penetrated through mutually in the modeling needle 3,
Vent plug 6 is equipped in the gas flow 5；Modeling 3 bottom of needle extends in dropping funnel 1 and forms dropper 7, institute in upper dropping funnel 1
State dropping funnel 1 outer wall bottom be outward extended with installation bulge loop 8, it is described installation bulge loop 8 bottom surface be extended with round inserted sheet 11, with
And the annular groove 10 of round 11 outer ring of inserted sheet is set；Several support rods 12 are equipped in the annular groove 10；The installation is convex
It is through with stomata 13 between the inner wall of the supreme dropping funnel 1 of the outer peripheral surface of ring 8, is equipped with air-filtering membrane in stomata 13；
Mounting flange 14 is outward extended at the top of the outer wall of the lower dropping funnel 2, the matching of mounting flange 14 is embedded in ring
In the shape slot 10 and end face of mounting flange 14 is against on several support rods 12, and circle inserted sheet 11 interference fit is plugged in down
The inner wall of dropping funnel 2；The lower dropping funnel 2 matches one docked with round inserted sheet 11 and is truncated into columnar structured 15, and rest part is circle
Bench-type structure 16；The bottom of the lower dropping funnel 2 is equipped with downcomer 17；Bubble filter membrane 18 is equipped in lower dropping funnel 2.
The matching of stomata 13 is in a wherein support rod 12.
The height of the upper dropping funnel 1 is the 2/3 of the height of lower dropping funnel 2.
14 top surface of mounting flange, annular groove 10, that accommodating is together formed between two adjacent support rods 12 is empty
Between 19.
It makes an explanation below to the working principle of the integrated-type dropping funnel of the utility model:
In use, in the space that medical fluid is formed from the medical fluid runner 4 of modeling needle 3 into upper dropping funnel 1 and lower dropping funnel 2, with medicine
The continuous rising of liquid liquid level, the air in dropping funnel is discharged from stomata 13, when liquid level rises to 13 position of stomata and covers stomata
When 13, according to the principle of the obstructed liquid of air-filtering membrane blowing air, positive air pressure is formd between upper dropping funnel 1 and liquid level, just
Medical fluid is pressed to bubble filter membrane 18 by air pressure, and medical fluid is seeped down from bubble filter membrane 18 and is discharged from downcomer 17.
The integrated-type dropping funnel of the utility model, upper dropping funnel 1 pass through round inserted sheet 11 and realize face sealing, structure with lower dropping funnel 2
