Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to specific embodiments.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a disposable funnel, which includes a funnel body 1, a flow guide tube 2, a connecting tube 4, a sleeve 3 and a handle 7, wherein the funnel body 1 is a tapered tubular structure, a small-diameter end of the funnel body 1 is in sealed communication with one end of the flow guide tube, and a large-diameter end of the funnel body is in sealed communication with one end of the connecting tube 4; one end of the sleeve is sleeved at the other end of the connecting pipe, the outer wall surface of the connecting pipe is provided with a first thread, and the inner wall of the sleeve is provided with a second thread matched with the first thread; a support plate 31 is horizontally arranged in the sleeve, a plurality of through holes 32 are formed in the support plate 31, and a filter layer is arranged on one surface, far away from the connecting pipe, of the support plate 31; a filter coating 6 is arranged on the inner wall of the funnel body; the handle 7 is arranged on the outer wall of the sleeve 3. It can be understood that, because the funnel body 1 is a conical cylindrical structure, the small-diameter end of the funnel body is the end with the smaller diameter on the funnel body, and the large-diameter end of the funnel body is the end with the larger diameter on the funnel body; the disposable funnel is convenient for operators to move through the handle; the support plate 31 may preferably be a circular plate, the diameter of the support plate is equal to the inner diameter of the sleeve, and the through holes may be uniformly distributed on the support plate; the filter layer may be laid flat on the support plate.

When the disposable funnel provided by the embodiment of the utility model is used, the sleeve 3 and the connecting pipe 4 are screwed through the matching of the first thread and the second thread, then the sleeve 3 is held by the hand, and the flow guide pipe 2 is inserted into a narrow-mouth liquid collecting bottle to be measured or the funnel body is arranged on the filter frame; then, the liquid to be measured which needs to be filtered is poured into the sleeve 3, the liquid flows into the funnel body 1 after being filtered by the filter layer, the liquid is filtered once by the filter coating on the inner wall of the funnel body, and finally flows into the sample collecting bottle or the container from the flow guide pipe, so that the double filtration of the extract liquid to be measured is realized. It is obvious by the above-mentioned process, the utility model discloses have better ground filter effect, also need not the manual paper folding of operating personnel to solved operating personnel's among the prior art effectively operation step more, because of the mode of artifical paper folding is not unified easily causes the poor problem of filter effect. Meanwhile, when the disposable funnel of the utility model is used for liquid drainage, the flow guide pipe can be directly inserted into a narrow-mouth container or equipment without installing a sleeve; then, the reagent is poured into the funnel body 1 from the connecting pipe, and the reagent flows into the narrow-mouth container or equipment from the flow guide pipe after being filtered by the filter coating on the inner wall of the funnel body, so that the reagent enters the narrow-mouth container or equipment after being filtered once. Therefore, the embodiment of the utility model provides a disposable funnel not only has the function of filtering the extract that awaits measuring, still has the function of liquid drainage and can make reagent filter the back when the drainage, reentries in the container or the equipment of slot.

Specifically, the two ends of the U-shaped rod are connected to the outer wall of the sleeve 3, respectively, so that the operator can conveniently grip the handle. It can be understood that the number of the handles 7 can be two, and the two handles are arranged oppositely, so that an operator can move the disposable funnel more conveniently.

In order to effectively improve the connection strength between the sleeve 3 and the handle 7, the sleeve and the handle are formed into an integral structure.

In particular, the filter layer is made of a full range of cellulose filter paper, glass or quartz fiber filter paper, so that the filter layer has a good filtering effect.

In order to enable a good filtering effect of the filter coating 6, the filter coating is made of a silk fibroin polyurethane material.

Further, the filter coating 6 is connected to the inner wall of the funnel body 1 by an adhesive.

Specifically, the connecting pipe 4, the funnel body 1, the honeycomb duct 2 forms into an integral structure, thereby making the connecting pipe 4 the funnel body 1 the leakproofness between the honeycomb duct 2 is better, has also saved simultaneously the operation of being connected between funnel body 1 and connecting pipe 4, the honeycomb duct 2.

Preferably, the funnel body 1, the flow guide pipe 2, the connecting pipe 4 and the sleeve 3 are all made of an acid-base-resistant and organic reagent-resistant plastic material, so that the funnel body, the flow guide pipe, the connecting pipe and the sleeve are low in cost and good in corrosion resistance. It can be understood that the plastic material resistant to acid, alkali and organic reagents can be polyvinyl chloride (PVC for short) or polypropylene (PP), etc.; the handle 7 can also be made of PVC or PP and other plastic materials with acid and alkali resistance and organic reagent resistance.

The disposable funnel provided by the embodiment of the utility model can save the steps of manual paper folding and manual drainage, and can directly filter the extract liquor to be measured; the filter also can be independently used as a drainage and filtering reagent for use, so that impurities in the reagent can be effectively filtered out primarily; meanwhile, the use is very convenient.

The above are only preferred embodiments of the present invention, and it should be noted that these examples are only used for illustrating the present invention and not for limiting the scope of the present invention, and after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalents also fall within the scope defined by the claims attached to the present application.
