Description

Technical Field

[0001] The utility model relates to the technical field of funnels, in particular to a funnel with filtering and metering functions. Background Art

[0002] A funnel is a cylindrical object used to pour liquids and powders into containers with relatively small entrances. In daily inspection work, inspectors need to pretreat samples and measure and quantify them into containers. When there are many impurities in the samples to be processed, centrifugal filtration is required for pretreatment, which is time-consuming. Moreover, using measuring instruments to quantify the pretreated samples into the target containers makes the whole process rather cumbersome. To solve this problem, we propose a funnel with filtering and metering functions. Content of the Utility Model

[0003] The purpose of the utility model is to solve the drawback in the prior art that impurities cannot be filtered, and to propose a funnel with filtering and metering functions.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Design a funnel with filtering and metering functions, including an upper funnel. A lower funnel is connected to the upper funnel. A connecting ear is fixedly connected to the upper funnel. A plurality of connecting plates are arranged on the connecting ear through an adjusting mechanism. Connecting edges are fixedly connected to the plurality of connecting plates. Connecting rings are arranged on the plurality of connecting edges. Filter membranes are connected in the plurality of connecting rings. The mesh holes of the plurality of filter membranes are all different. A measuring meter is arranged on the lower funnel.

[0006] Preferably, the adjusting mechanism includes a connecting cylinder. One end of the connecting cylinder is fixedly connected to the connecting ear, and the other end is inserted with a column, and the column can be pulled out of the connecting cylinder. The column is fixedly connected to the plurality of connecting plates.

[0007] Preferably, a threaded rod is threadedly penetrated through one of the connecting edges. An abutting block is fixedly connected to the threaded rod, and the abutting block can abut against the connecting cylinder.

[0008] Preferably, a fixing block is fixedly connected to the connecting edge. A screw is threadedly penetrated through the fixing block, and the screw is threadedly connected to the connecting ring.

[0009] Preferably, non-stick layers are arranged on the inner walls of the upper funnel and the lower funnel.

[0010] A funnel with filtering and metering functions proposed by the present utility model has the beneficial effects that the filter membrane plays a filtering role to filter the passing liquid. At the same time, different filter membranes can be adjusted to be located in the upper funnel to meet the requirements of different particle impurities and different filtering requirements.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Embodiment 1

[0018] Referring to Figures 1-3 , a funnel with filtering and metering functions includes an upper funnel 1. A lower funnel 2 is communicatively provided on the upper funnel 1. A connecting ear 13 is fixedly connected to the upper funnel 1. A plurality of connecting plates 5 are provided on the connecting ear 13 through an adjusting mechanism. Connecting edges 6 are fixedly connected to the plurality of connecting plates 5. Connecting rings 3 are provided on the plurality of connecting edges 6. The outer wall of the connecting ring 3 abuts against the upper funnel 1. Filter membranes 4 are connected in the plurality of connecting rings 3. The mesh holes of the plurality of filter membranes 4 are all different. The filter membrane 4 plays a filtering role to filter the passing liquid. At the same time, different filter membranes 4 can be adjusted to be located in the upper funnel 1 to meet the requirements of different particle impurities and different filtering requirements.

[0019] A metering table 14 is provided on the lower funnel 2 to play a metering role to meter the filtered liquid.

[0020] The adjusting mechanism includes a connecting cylinder 7. One end of the connecting cylinder 7 is fixedly connected with a connecting ear 13, and the other end is inserted with a column 12. The column 12 is fixedly connected with a plurality of connecting plates 5. By pulling out the column 12 from the connecting cylinder 7 and rotating the column 12, filter membranes 4 with different mesh holes are placed on the upper funnel 1, which plays a role in adjusting the filtration accuracy.

[0021] One of the connecting edges 6 is threadedly penetrated and connected with a threaded rod 8. A butting block 11 is fixedly connected to the threaded rod 8. The butting block 11 can abut against the connecting cylinder 7. By rotating the threaded rod 8, the butting block 11 will abut against the connecting cylinder 7, thereby fixing the column 12 and fixing the position of the column 12 in the connecting cylinder 7.

[0022] During adjustment, by twisting the threaded rod 8, the column 12 is pulled out from the connecting cylinder 7, the column 12 is rotated, the filter membranes 4 with different mesh holes are placed on the upper funnel 1, and then the column 12 is reinserted. By tightening the threaded rod 8, the butting block 11 is abutted against the connecting cylinder 7 to fix the position of the column 12.
