[0019] In this embodiment, the filter section is V-shaped, which ensures the overall filtration area of ​​the high-efficiency filter layer 2 while keeping the overall size of the filter screen fixed, thereby improving the filtration efficiency; while the connecting section 2a can both connect the filter section and serve as a filter section of the high-efficiency filter layer 2, thereby ensuring the overall filtration effect of the high-efficiency filter layer 2.

[0020] Example 3: This embodiment provides a high-efficiency filter, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0021] The filter components include: The left filter section 2b is located on one side; The right filter section 2c is located on the other side and is a mirror image of the left filter section 2b; The receiving part 2d connects the bottom of the left filter part 2b and the right filter part 2c; Multiple interception sections are formed between the left filter section 2b and the right filter section 2c on the same filter section, as well as between the adjacent left filter section 2b and the right filter section 2c. The support rod 4 is respectively set on the connection section 2a and the receiving section 2d in the high-efficiency filter layer 2.

[0022] In this embodiment, the high-efficiency filter can be a single-layer metal mesh structure or a mesh structure made of a non-metallic material with high hardness and resistance to deformation; it can also be a double-layer structure, including a mesh-like support frame made of metal or non-metallic material to support and prevent deformation, and a flexible filter covering the support frame. The receiving part 2d of the filtration section connects the left filter section 2b and the right filter section 2c to ensure the continuity of the filtration section; and multiple filter interception parts are formed between the left filter section 2b and the right filter section 2c on the filtration section, as well as between adjacent left filter sections 2b and right filter sections 2c, so that the substance to be filtered can be filtered multiple times when passing through the high-efficiency filter layer 2, and multiple filtrations are completed through one filter to ensure the filtration effect.

[0023] Example 4: This embodiment provides a high-efficiency filter, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0024] The left filter section 2b and the right filter section 2c both include the following components connected sequentially from top to bottom: The upper connecting section 201 is inclined from bottom to bottom towards the middle of the filter part; The middle receiving section 202 is inclined from top to bottom towards the middle of the filter part; The lower connecting section 203 is an inclined section that slopes towards the middle of the filter section from the top down.

[0025] In this embodiment, both the left filter section 2b and the right filter section 2c include an upper receiving section 201, a middle receiving section 202 and a lower receiving section 203 connected by a side fold line, so that the two sides of the filter section form a non-flat filter surface, thereby increasing the number of contactes when the filter material passes through, and thus ensuring the number of filtrations.

[0027] Both the left filter section 2b and the right filter section 2c also include: The first interception section 204 is located in the middle of the upper receiving section 201, and is arc-shaped, with the top of the arc facing away from the middle of the filtering part. The second interception section 205 is located at the connection between the upper receiving section 201 and the lower receiving section 203. It is arc-shaped, and the top of the arc is set towards the middle of the filter part. Two second intercepting segments 205 on the same filtering part abut against each other to form a first intercepting part 206; adjacent first intercepting segments 204 in adjacent filtering parts abut against each other to form a second intercepting part 207.

[0028] In this embodiment, the first interception section 206 and the second interception section 207 formed enable the substance to be filtered to pass through the upper receiving section 201 and the middle receiving section 202 to increase the number of filtrations by at least one, thereby ensuring the filtration effect.

[0031] In this embodiment, the third interception section 209 is provided so that the substance to be filtered is filtered again when it passes between adjacent filtration sections, thereby improving the filtration effect.

[0032] Example 7: This embodiment provides a high-efficiency filter, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0034] In this embodiment, the fourth intercepting section 211 allows the material to be filtered to pass through the lower receiving section 203 in the middle of the filtration section for further filtration. To ensure the stability of the intercepting section structure, the intercepting sections on the intercepting section can be connected and fixed by means of adhesives, heat fusion, etc.; alternatively, retaining rods can be provided on the filter frame 1 to support and limit the intercepting sections. With the four intercepting sections, the material to be filtered must pass through at least two of the four intercepting sections when passing through the high-efficiency filter layer 2, thereby greatly improving the filtration effect and performance of the high-efficiency filter layer 2.
