[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-4 As shown, a high-efficiency Y-type filter comprises a filter 1 provided with a cover 11, and also comprises a concave hole 12 opened on the cover 11, and a filter screen 2 is movably arranged in the concave hole 12;

[0025] A plurality of inclined mesh plates 21 are arranged in a circumferential array inside the filter screen 2 . The fluid in the filter 1 impacts the plurality of inclined mesh plates 21 to drive the filter screen 2 to rotate circumferentially in the concave hole 12 .

[0026] Specifically, the angle between the inclined mesh plate 21 and the fixed connection position of the filter 2 is 60°, and a lubricating pad (the surface of which is coated with lubricating material, which is the prior art and will not be described here) is fixedly installed in the concave hole 12 to increase the smoothness of the rotation of the filter 2. The filter 2 body is the prior art and will not be described here.

[0027] When liquid flows through the filter 1, the liquid enters the filter screen 2 and impacts multiple inclined mesh plates 21, so that the fluid drives the filter screen 2 to deflect along the acute angle direction of the inclined mesh plates 21, so that the filter screen 2 can rotate circumferentially in the concave hole 12, so that the filter screen 2 can continuously switch the filtering surface when filtering the debris in the liquid, avoiding the situation that the filter screen 2 uses only a single surface for filtering and aggravates the clogging of debris, thereby making the filter screen 2 have a longer filtering energy efficiency and increasing the service life and working efficiency of the filter 1.

[0028] As an embodiment further provided by the present invention, a mesh protrusion 22 is fixedly mounted on the inclined mesh plate 21 , and the mesh protrusion 22 cooperates with the inclined mesh plate 21 to form a drainage section 222 .

[0029] Specifically, the mesh protrusion 22 and the inclined mesh plate 21 form a “J” shape, and the drainage section 222 is located between the “J” shape and the inner wall of the filter screen 2 .

[0030] During the rotation of the filter screen 2, the mesh protrusions 22 shovel the liquid debris on the axial part of the filter screen 2 into the drainage section 222, so that the debris in the drainage section 222 can adhere to the inclined mesh plate 21, so as to reduce the interference of the debris on the filtering of the side wall of the filter screen 2 and ensure the filtering efficiency of the filter screen 2.

[0031] As another embodiment further provided by the present invention, a plurality of mesh protrusions 22 are driven by the filter screen 2 to rotate to form a retention section 221 , and the retention section 221 is communicated and matched with the drainage section 222 .

[0032] Specifically, the retention section 221 is the area isolated between the mesh protrusion 22 and the inner wall of the filter screen 2 during the rotation of the filter screen 2.

[0033] During the rotation of the filter screen 2, the liquid at the axis is continuously replenished into the retention section 221, so that the debris in the liquid of the retention section 221 can be gradually subjected to the centrifugal force and be located at the intersection of the mesh protrusion 22 and the inclined mesh plate 21, so as to improve the adhesion effect of the drainage section 222 on the debris, and further reduce the interference of the debris with the filtering function of the side wall of the filter screen 2.

[0034] As another embodiment further provided by the present invention, a blade plate 23 is fixedly mounted at the end of the inclined screen plate 21 , and a plurality of blade plates 23 cooperate with the filter screen 2 to rotate to form a convergence section 231 , and the convergence section 231 is connected to the concave hole 12 .

[0035] Specifically, the plurality of blade plates 23 have the function of conveying liquid to the converging section 231 .

[0036] During the rotation of the filter 2, the multiple blade plates 23 extract the liquid at the axis of the filter 2 into the convergence section 231, so that the debris in the axis of the filter 2 can be continuously replenished into the convergence section 231, so that the debris in the convergence section 231 area is accumulated and absorbed into the concave hole 12, so that the filter 2 can be quickly rinsed and cleaned when the cover 11 is removed later, reducing the workload.

[0037] As another embodiment further provided by the present invention, the drainage section 222 is connected and coordinated with the convergence section 231 .

[0038] When the debris is extracted by the multiple blade plates 23, the liquid debris in the drainage section 222 is gradually extracted by the multiple blade plates 23 and the debris is added to the converging section 231, so that the converging section 231 can finally collect the debris and reduce the interference of the debris on the filtering work of the filter screen 2, the inclined screen plate 21 and the screen protrusion 22.

[0039] As another embodiment further provided by the present invention, the inclined mesh plate 21 is specifically a stainless steel metal mesh.

[0040] Since the inclined mesh plate 21, mesh protrusion 22 and blade plate 23 are all stainless steel metal meshes, the three can ensure the filtering effect and debris extraction and accumulation effect of the filter screen 2 when driving the filter screen 2 to rotate and extract debris. At the same time, they also have higher corrosion resistance and increase the service life of the filter screen 2.

[0041] Working principle: When the liquid flows through the filter 1, the liquid enters the filter screen 2 and impacts multiple inclined mesh plates 21, so that the fluid drives the filter screen 2 to deflect along the acute angle direction of the inclined mesh plates 21, so that the filter screen 2 can rotate circumferentially in the concave hole 12, so that the filter screen 2 can continuously switch the filtering surface when filtering the debris in the liquid, avoiding the situation that the filter screen 2 uses only a single surface for filtering and aggravates the clogging of debris. In addition, during the rotation of the filter screen 2, the multiple blade plates 23 extract the liquid at the axis of the filter screen 2 into the convergence section 231, so that the debris in the axis of the filter screen 2 can be continuously replenished into the convergence section 231, so that the debris in the convergence section 231 area is accumulated and absorbed into the concave hole 12, so that the filter screen 2 can be quickly rinsed and cleaned when the cover 11 is removed later.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
