Description

Technical Field

[0001] The present application belongs to the technical field of laboratory material transfer instruments, and more specifically, to a funnel structure. Background Art

[0002] In some testing and analysis experiments, it is usually necessary to use a funnel to assist in the transfer of materials. For example, in soil testing experiments, a funnel is needed to transfer the dried and homogenized soil sample to the corresponding extraction device, or in water testing experiments, a funnel is needed to transfer sodium chloride as a demulsifier to the corresponding water collection container, or in the drying process of the extract in some testing experiments, a funnel is needed to transfer anhydrous sodium sulfate to the corresponding drying column to dry the extract.

[0003] In the above-mentioned material transfer steps, there are certain differences in the particle sizes of different materials and the corresponding receiving diameters of different receiving containers. Therefore, in order to ensure the integrity or completeness of the materials, funnels with different diameters (mainly referring to the diameter of the narrow mouth of the funnel body) are required to transfer the materials. However, the existing funnel structure usually has a fixed diameter and cannot be adaptively adjusted based on different materials or different receiving containers, which leads to a lack of versatility and thus affects the cost efficiency of the laboratory. Utility Model Content

[0006] When the multiple movable curved plates cooperate to move in a first state, the multiple movable curved plates are relatively separated and avoid the narrow mouth end and the wide mouth end of the first bucket body. When the multiple movable curved plates cooperate to move in a second state, the multiple movable curved plates are relatively close to each other and form a conical second bucket body. The wide mouth end of the second bucket body is adapted to be connected to the narrow mouth end of the first bucket body, and the diameter of the narrow mouth end of the second bucket body is smaller than the diameter of the narrow mouth end of the first bucket body.

When the plurality of movable curved plates cooperate to move in a first state, the plurality of movable curved plates are relatively separated and contained in the first bucket body. When the plurality of movable curved plates cooperate to move in a second state, the plurality of movable curved plates extend out of the narrow end of the first bucket body along the inclined extension direction of the first bucket body and are relatively close to form a second bucket body.

[0008] In one of the embodiments, the first bucket body is coaxially provided with a conical hollow ring layer, one end of the hollow ring layer penetrates the narrow end of the first bucket body and forms an annular notch, and multiple movable curved plates are respectively movably connected in the hollow ring layer along the inclined extension direction of the first bucket body. When the multiple movable curved plates cooperate to move in a first state, the multiple movable curved plates are relatively separated and contained in the hollow ring layer. When the multiple movable curved plates cooperate to move in a second state, the multiple movable curved plates extend out of the narrow end of the first bucket body through the annular notch along the inclined extension direction of the first bucket body, and are relatively close to form a second bucket body.

[0010] In one embodiment, the extension direction of each guide connection part in the multiple limiting grooves is the inclined extension direction of the first bucket body, and the extension direction of each first limiting part and the extension direction of each second limiting part are tangent to the inclined extension direction of the first bucket body.

[0011] In one embodiment, the funnel structure includes two movable curved plates, and the outer wall of the first bucket body is provided with two limit grooves corresponding to the two movable curved plates. The two movable curved plates are fixedly connected to two movable levers corresponding to each other. When the two movable curved plates cooperate to move in a first state, the two movable levers are respectively limited in the first limit portions of the two limit grooves corresponding to each other along the inclined extension direction of the first bucket body. When the two movable curved plates cooperate to move in a second state, the two movable levers are respectively limited in the second limit portions of the two limit grooves corresponding to each other along the inclined extension direction of the first bucket body.
