[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The present invention provides a filtering device 100, which is used to be arranged in a container 200. The filtering device 100 can filter large-sized solid substances in liquid.

[0035] Please refer to Figure 1 As shown, a filter device 100 according to an embodiment of the present invention includes a positioning component 110 , a mounting component 120 and a filter screen 130 .

[0036] The positioning component 110 includes a fixing member 112 and a positioning collar 114. The fixing member 112 is used to be connected to the container 200. The positioning collar 114 is connected to the fixing member 112, and a limiting groove (not shown in the figure) is provided on the positioning collar 114.

[0037] The mounting member 120 has a mounting rod 122 and a stopper (not shown), which is disposed on the side wall of the mounting rod 122. The mounting rod 122 passes through the positioning collar 114, and the stopper is embedded in the stopper groove, so that the mounting rod 122 can be detachably mounted on the positioning member 110.

[0038] The filter screen 130 is provided with a mounting hole, and the mounting rod 122 passes through the mounting hole and is connected to the filter screen 130 .

[0039] The filter device 100 is provided with a positioning component 110 and a mounting component 120 for mounting the filter screen 130. The positioning component 110 includes a mounting rod 122 and a stopper. The filter screen 130 is arranged on the mounting rod 122. The positioning component 110 includes a fixing member 112 and a positioning collar 114. The positioning collar 114 is mounted in the container 200 through the fixing member 112. A stopper groove cooperating with the stopper groove is provided on the positioning collar 114. When the filter device 100 is installed in the container 200 for filtration, the mounting rod 122 is taken, the mounting rod 122 is passed through the positioning collar 114, and the stopper groove is embedded in the stopper groove, so that the filter device 100 can be installed without tools, which is easy to operate and is conducive to improving work efficiency.

[0040] In one example, the embedded cavity fixing member 112 includes a fixing rod, one end of which is connected to the outer wall of the embedded cavity positioning collar 114 , and the other end of which is used to be connected to the container 200 .

[0041] Optionally, the number of the fixing rods is not limited to only one, and may be multiple, such as 2, 3, 4, etc. By connecting multiple fixing rods to the positioning collar 114, the connection stability can be improved.

[0042] In one example, the positioning collar 114 is a circular ring structure. In one example, the inner diameter (inner hole diameter) of the positioning collar 114 is 1 cm to 10 cm. Further, in one example, the inner diameter of the positioning collar 114 is 2 cm to 8 cm. In some specific examples, the inner diameter of the positioning collar 114 is 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, etc.

[0043] The positioning collar 114 is provided with a notch to form a limiting groove for cooperating with a limiting piece provided on the side wall of the mounting rod 122 .

[0044] In one example, the limiting groove includes a first embedding cavity. The first embedding cavity extends from one end of the positioning collar 114 along the axial direction of the positioning collar 114. In this example, the limiting member of the mounting component 120 moves along the axial direction of the positioning collar 114 and can be embedded in the first embedding cavity.

[0045] Furthermore, in one example, the limiting groove also includes a second embedding cavity. The second embedding cavity is connected to the first embedding cavity. The second embedding cavity extends from the bottom of the first embedding cavity along the circumference of the positioning collar 114. In this example, after the limiting piece of the mounting component 120 is embedded in the first embedding cavity, the limiting piece can be embedded in the second embedding cavity by rotating the mounting rod 122. In this way, the mounting component 120 and the filter screen 130 can be positioned in the axial direction of the positioning collar 114, thereby improving the installation stability of the filter screen 130 and improving the anti-loosening property of the filter screen 130.

[0046] Optionally, the number of upper limit grooves on the positioning collar 114 is not limited to only one, and may be multiple, such as 2, 3, 4, etc. In one example, the number of upper limit grooves on the positioning collar 114 is multiple, and the multiple limit grooves are evenly distributed along the circumference of the positioning collar 114. Correspondingly, the mounting component 120 also has multiple limit members, which correspond one-to-one to the multiple limit grooves.

[0047] In one example, the mounting component 120 further includes a handle 126, which is disposed on the mounting rod 122 and is located on a side of the filter screen 130 away from the stopper. The handle 126 can facilitate operators to lift and rotate the filter device 100.

[0048] The cross-sectional size of the mounting rod 122 at the position where it is positioned with the positioning collar 114 is consistent with the inner diameter of the positioning collar 114, so that the mounting rod 122 can be stably mounted on the positioning collar 114. For example, in a specific example, the cross-sectional diameter of the mounting rod 122 at the position where it is positioned with the positioning collar 114 is 2 cm, and the inner diameter of the positioning collar 114 is also 2 cm.

[0049] In one example, one end of the mounting rod 122 for passing through the positioning collar 114 is a tapered end. The size of the tapered end is smaller than the diameter of the positioning collar 114, which facilitates the insertion of the mounting rod 122. When the filter 130 needs to be installed, the tapered end of the mounting rod 122 is aligned with the positioning collar 114 to achieve quick positioning and installation.

[0050] Optionally, the filter screen 130 may be, but is not limited to, a metal screen, a plastic screen, a gauze screen, etc. In one example, the filter screen 130 is made of stainless steel.

[0051] Optionally, the filter screen 130 and the mounting rod 122 may be connected by welding, bonding, or the like.

[0052] In one example, the filter screen 130 is a conical structure. More specifically, as the liquid flows, the size of the conical structure gradually decreases. The filter screen 130 is set as a conical structure, which can increase the filtering area. In this example, the mounting hole of the filter screen 130 is located at the top of the conical structure.

[0053] Optionally, the conical surface structure may be a conical structure, a pyramidal structure, or the like.

[0054] It is understandable that in other examples, the filter 130 is not limited to a conical structure, but may be other shapes. For example, the filter 130 may also be a planar structure, etc., and may be specifically configured according to the bottom shape of the container 200 and other requirements.

[0055] In one example, the filter device 100 further includes a hydrophobic ring 140 , which is disposed along the periphery of the filter screen 130 .

[0056] The filter device 100 in the above example is provided with a hydrophobic ring 140 on the periphery of the filter net 130 . The hydrophobic effect of the hydrophobic ring 140 can prevent liquid from passing through the edge of the filter net 130 without being filtered.

[0057] The hydrophobic ring 140 may be made of a hydrophobic material, such as but not limited to rubber, polytetrafluoroethylene, etc. Or at least the surface portion of the hydrophobic ring 140 is made of a hydrophobic material, for example, the surface of the hydrophobic ring 140 has a hydrophobic coating, such as Teflon coating, etc.

[0058] Preferably, the contact angle between the hydrophobic material and water is greater than 90°. Further, the contact angle between the hydrophobic material and water is greater than 100°. Further, the contact angle between the hydrophobic material and water is greater than 110°.

[0059] In one example, the contact angle between the hydrophobic material and water is 90° to 165°. Further, in one example, the contact angle between the hydrophobic material and water is 100° to 165°. Further, in one example, the contact angle between the hydrophobic material and water is 110° to 165°. In some specific examples, the contact angle between the hydrophobic material and water is 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, etc.

[0060] Please refer to Figure 2 As shown, further, the present invention also provides a storage device 10 with a filtering function, including a container 400 and a filtering device 300.

[0061] The filter device 300 is disposed in the container 400 .

[0062] The filter device 300 includes a positioning component 310 , a mounting component 320 and a filter net 330 .

[0063] The positioning member 310 includes a fixing member 312 and a positioning collar 314. The fixing member 312 is used to be connected to the container 400. The positioning collar 314 is connected to the fixing member 312, and a limiting groove (not shown in the figure) is provided on the positioning collar 314.

[0064] The mounting member 320 has a mounting rod 322 and a stopper (not shown), which is disposed on the side wall of the mounting rod 322. The mounting rod 322 passes through the positioning collar 314, and the stopper is embedded in the stopper groove, so that the mounting rod 322 can be detachably mounted on the positioning member 310.

The filtering device 300 is provided with a positioning component 310 and a mounting component 320 for mounting a filter net 330, wherein the positioning component 310 comprises a mounting rod 322 and a stopper, wherein the filter net 330 is arranged on the mounting rod 322, and the positioning component 310 comprises a fixing member 312 and a positioning collar 314, wherein the positioning collar 314 is mounted in the container 400 through the fixing member 312, and a stopper groove cooperating with the stopper groove is provided on the positioning collar 314. When the filtering device 300 is installed in the container 400 for filtering, the mounting rod 322 is taken, the mounting rod 322 is passed through the positioning collar 314, and the stopper groove is embedded in the stopper groove, thereby realizing tool-free installation of the filtering device 300, which is easy to operate and conducive to improving work efficiency.

[0067] In one example, the container 400 includes a storage chamber 410 and a discharge pipe 420. The storage chamber 410 has a discharge port at the bottom thereof, the discharge pipe 420 is connected to the discharge port, the fixing member 312 is connected to the inner wall of the discharge pipe 420, and the positioning collar 314 is mounted at the discharge port through the fixing member 312. Furthermore, the filter screen 330 is laid at the bottom of the storage chamber 410.

[0068] In one example, the embedded cavity fixing member 312 includes a fixing rod, one end of which is connected to the outer wall of the embedded cavity positioning collar 314 , and the other end of which is used to be connected to the container 400 .

[0069] Optionally, the number of the fixing rods is not limited to only one, and may be multiple, such as 2, 3, 4, etc. By connecting multiple fixing rods to the positioning collar 314, the connection stability can be improved.

[0070] In one example, the positioning collar 314 is a circular ring structure. In one example, the inner diameter (inner hole diameter) of the positioning collar 314 is 1 cm to 10 cm. Further, in one example, the inner diameter of the positioning collar 314 is 2 cm to 8 cm. In some specific examples, the inner diameter of the positioning collar 314 is 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, etc.

[0071] The positioning collar 314 is provided with a notch to form a limiting groove for cooperating with a limiting member provided on the side wall of the mounting rod 322 .

[0072] In one example, the limiting groove includes a first embedding cavity. The first embedding cavity extends from one end of the positioning collar 314 along the axial direction of the positioning collar 314. In this example, the limiting member of the mounting component 320 moves along the axial direction of the positioning collar 314 and can be embedded in the first embedding cavity.

[0073] Furthermore, in one example, the limiting groove also includes a second embedding cavity. The second embedding cavity is connected to the first embedding cavity. The second embedding cavity extends from the bottom of the first embedding cavity along the circumference of the positioning collar 314. In this example, after the limiting piece of the mounting component 320 is embedded in the first embedding cavity, the limiting piece can be embedded in the second embedding cavity by rotating the mounting rod 322. In this way, the mounting component 320 and the filter screen 330 can be positioned in the axial direction of the positioning collar 314, thereby improving the installation stability of the filter screen 330 and improving the anti-loosening property of the filter screen 330.

[0074] Optionally, the number of upper limit grooves on the positioning collar 314 is not limited to only one, and may be multiple, such as 2, 3, 4, etc. In one example, the number of upper limit grooves on the positioning collar 314 is multiple, and the multiple limit grooves are evenly distributed along the circumference of the positioning collar 314.

For example, in a specific example, the cross-sectional diameter of the mounting rod 322 at the position where it is positioned with the positioning collar 314 is 2 cm, and the inner diameter of the positioning collar 314 is also 2 cm.

[0077] In one example, one end of the mounting rod 322 for passing through the positioning collar 314 is a tapered end. The size of the tapered end is smaller than the caliber of the positioning collar 314, which facilitates the insertion of the mounting rod 322. When the filter 330 needs to be installed, the tapered end of the mounting rod 322 is aligned with the positioning collar 314 to achieve rapid positioning and installation.

[0078] Optionally, the filter mesh 330 may be, but is not limited to, a metal mesh, a plastic mesh, a gauze mesh, etc. In one example, the filter mesh 330 is made of stainless steel.

[0082] It is understandable that in other examples, the filter 330 is not limited to a conical structure, but may be other shapes. For example, the filter 330 may be a planar structure, etc., and may be specifically configured according to the bottom shape of the container 400 and other requirements.

[0083] In one example, the filter device 300 further includes a hydrophobic ring 340 , which is disposed along the periphery of the filter net 330 .

[0084] The filter device 300 in the above example is provided with a hydrophobic ring 340 on the periphery of the filter net 330 . The hydrophobic effect of the hydrophobic ring 340 can prevent liquid from passing through the edge of the filter net 330 without being filtered.
