Abstract
The utility model provides a filtering funnel, relating to the technical field of the filtering funnel, in particular to the technical field of the filtering funnel for testing, analyzing and measuring. The filtering funnel comprises a funnel main body and a drainage tube body which is arranged at the lower part of the funnel main body, wherein the inner wall of the funnel main body is evenly provided with a plurality of convex parts. Each convex part is in the shape of strip and is extended to a combination part between the funnel main body and the drainage tube body from the edge of the funnel main body. The convex parts are floating points which are evenly arranged at the inner wall of the funnel main body. The filtering funnel achieves the aims of being simple in structure, improving the filtering effect, and improving the filtering speed.
Description
Technical field
The utility model relates to the technical field of filter tunnel, relates in particular to the technical field of the filter tunnel of test, analysis, metering usefulness.
Background technology
The funnel of test at present, analysis, metering usefulness is generally glassware.Mouth sticking distilled water in circular filter paper doubling secondary back need be attached to the funnel conical wall during use, and then inject solution and filter.In this process, along with oozing out of solution, filter paper will tightly attach the smooth inner wall of funnel, cause filter efficiency low, in order to change these phenomenons, need the smooth inner wall of funnel be improved.
Summary of the invention
The utility model purpose provides a kind of simple in structure, improves filter effect, improves the filter tunnel of the rate of filtration.
The utility model adopts following technical scheme for achieving the above object:
A kind of filter tunnel comprises funnel body and is arranged on the drainage body of funnel body bottom, it is characterized in that on the inwall of funnel body some protruding parts being set evenly.
Protruding part of the present utility model is a strip, extends to the joint portion of funnel body and drainage body from the edge of funnel body.
Protruding part of the present utility model is a floating-point, is evenly arranged in the inwall of funnel body.
The utility model adopts technique scheme, compared with prior art have following advantage: the utility model adopts the strip protruding part that the inwall of funnel body is divided into several regions, each zone is corrugated clocklike, ripple is sinusoidal waveform or other waveform clocklike, perhaps the protruding floating-point that distributes with rule of the inwall of funnel body.Prevent that filter paper from tightly sticking to the funnel inwall after running into liquid, realized can between filter paper and funnel inwall, dripping fast from the liquid that filter paper oozes out, simple in structure, improved the filter effect and the rate of filtration.
Description of drawings
Fig. 1 is the schematic diagram that partly cuts open of the present utility model.
Fig. 2 is 180 ° schematic diagram after the utility model funnel inwall launches.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1 and Figure 2, a kind of filter tunnel comprises funnel body and is arranged on the drainage body of funnel body bottom, it is characterized in that on the inwall of funnel body some protruding parts being set evenly.
As shown in Figure 1, protruding part of the present utility model is a strip, extends to the joint portion of funnel body and drainage body from the edge of funnel body.Funnel body 2 inwalls are corrugated clocklike, form crimp ring 1.Forming crimp ring 1 has trough 3 and crest 4, and funnel body has drainage body 52 times.
As shown in Figure 2, funnel body 2 inwalls are 180 ° after launching fast, and inwall is divided into several regions, and each zone all presents corrugated clocklike.
Protruding part of the present utility model is a floating-point, is evenly arranged in the inwall of funnel body.
Claims (3)
