[0018] Please refer to Figures 1 to 4 The embodiments of the utility model will be described below through specific examples. Those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification.

[0019] It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for the understanding and reading of those skilled in the art, and do not define the limiting conditions for the implementation of the utility model, so they do not have technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "left", "right", "up", "down" and "one" used in the specification are only for the convenience of clear description, and are not used to limit the scope of the utility model. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the implementation of the utility model.

[0020] Please combine Figure 1 , Figure 2 and Figure 3In the first embodiment, a filtering funnel 1 comprises a hopper 11, a filtering part 12, an ear part 13 and a supporting part 14, the hopper 11 is tapered from wide top to narrow bottom; the filtering part 12 is fixed at the lower end of the hopper 11, the filtering part 12 is double-layer structure, used for separating the filtering liquid and the residue; the ear part 13 is arranged on the outer wall of the upper end of the hopper 11, facilitating the operator to take the filtering funnel 1; the supporting part 14 is arranged on the outer wall of the lower half of the hopper 11, facilitating the filtering funnel 1 to be placed on the liquid collecting device.

[0021] Specifically, the cross section of the hopper 11 can be circular, rectangular, polygonal or other geometric shapes.

[0022] The hopper 11 comprises a main body 111 and a fixed ring 112, the lower end of the main body 111 extends inward to form the fixed ring 112, the fixed ring 112 facilitates the installation of the filtering part 12.

[0023] The filtering part 12 comprises a first filter screen 121, a second filter screen 122 and a protection ring 123, the first filter screen 121 is above the second filter screen 122, the second filter screen 122 is used to support the first filter screen 121, thereby enhancing the strength of the first filter screen 121 and prolonging the service life of the first filter screen 121; the protection ring 123 wraps the edges of the first filter screen 121 and the second filter screen 122, the protection ring 123 and the fixed ring 112 are fixedly connected, used for protecting the first filter screen 121 and the second filter screen 122 and fixing the first filter screen 121 and the second filter screen 122 in the hopper 11.

[0024] Specifically, the first filter screen 121 is a dense filter screen, and the second filter screen 122 is a coarse filter screen, because the first filter screen 121 has smaller mesh holes, the overall hardness of the first filter screen 121 is smaller, when filtering, the weight of the solid-liquid mixture to be filtered presses on the first filter screen 121, after a long time of use, the first filter screen 121 has a probability of breaking or falling off, the second filter screen 122 has larger mesh holes but the overall hardness is larger, when the first filter screen 121 drops, the second filter screen 122 supports the first filter screen 121, providing a supporting force for the first filter screen 121, thereby prolonging the service life of the first filter screen 121.

[0025] The ear part 13 comprises ear pieces 131 and hanging holes 132, at least two ear pieces 131 are fixed symmetrically on the outer wall of the upper end of the hopper 11; the hanging holes 132 are arranged on the ear pieces 131, at least one ear piece 131 is provided with the hanging hole 132, facilitating the suspension storage of the filtering funnel 1.

[0026] The support part 14 includes a support member 141, which is fixedly installed on the outer wall of the lower half of the bucket part 11 to support the filter funnel 1 and place the filter funnel 1 on the liquid collection device.

[0027] Specifically, the support member 141 can be one or more components for support, and can be columnar, block-shaped, mesh-like or other structures that facilitate support.

[0028] like Figure 4 As shown, based on the basic shape of the first embodiment described above, this utility model also proposes a second embodiment. In this embodiment, the bottom of the filter funnel 1 is detachable, and the filter funnel 1 further includes a replacement part 15. The replacement part 15 is detachably installed at the lower end of the funnel 11, and the lower end of the replacement part 15 can extend inward to replace the fixing ring 112 in the first embodiment. Correspondingly, the filter part 12 is installed on the replacement part 15, and the protective ring 123 is fixedly connected to the lower extension of the replacement part 15. By disassembling the replacement part 15, the first filter screen 121 and the second filter screen 122 can be replaced. The support part 14 can be fixed to the outer wall of the funnel 11 and not disassembled with the replacement part 15. Alternatively, the support part 14 can be fixed to the replacement part 15 and used interchangeably with the replacement part 15 to suit different occasions.

[0029] In summary, the filter funnel provided by this utility model has a simple structure, strong practicality, and long service life.

[0030] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
