[0031] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0034] According to some embodiments of the present invention, referring to Figures 1 to 6 The rotatable self-flushing filter element includes a filter bottle 100 and a filter assembly 200. The filter bottle 100 is cylindrical, and a water inlet 110 is provided at the upper end of the filter bottle 100, and a sewage discharge hole 120 is provided at the lower end of the filter bottle 100. The filter assembly 200 is located in the filter bottle 100. The filter assembly 200 includes a telescopic frame 210 and a filter material 220. The filter material 220 is cylindrical and is sleeved on the telescopic frame 210. The filter assembly 200 is provided with a water outlet pipe 231 and a sewage discharge pipe 232. The water outlet pipe 231 is upwardly penetrated through the water inlet 110 and is connected to the inner cavity of the telescopic frame 210. The sewage discharge pipe 232 is downwardly penetrated through the sewage discharge hole 120, and the outer peripheral wall of the sewage discharge pipe 232 is closely attached to the hole wall of the sewage discharge hole 120.

[0035] Reference Figure 2 and Figure 6 When the telescopic frame 210 is rotated to extend the telescopic frame 210, the sewage pipe 232 is connected to the inner cavity of the filter bottle 100, the filter material 220 is in a straightened state, and the outer surface of the filter material 220 along the circumferential direction is smooth. The rotatable self-flushing filter element enters the self-flushing state. After the liquid enters the filter bottle 100 through the annular gap between the inner circumferential wall of the water inlet hole 110 and the outer circumferential wall of the water outlet pipe 231, the liquid flushes the outer surface of the filter material 220 to flush the filter material 220, and then the liquid enters the sewage pipe 232 and is discharged.

[0036] Reference Figure 1 and Figure 5 When the telescopic frame 210 is rotated to shorten the telescopic frame 210, the sewage pipe 232 is separated from the inner cavity of the filter bottle 100, and the filter material 220 is in a twisted state, that is, the outer surface of the filter material 220 along the circumferential direction is twisted to form a spiral shape, and the rotatable self-flushing filter element enters the filtering state. After the liquid enters the filter bottle 100 through the annular gap between the inner circumferential wall of the water inlet hole 110 and the outer circumferential wall of the water outlet pipe 231, the liquid enters the inner cavity of the telescopic frame 210 after being filtered by the filter material 220, and then enters the water outlet pipe 231 and is discharged.

[0037] It should be noted that when the outer surface of the filter material 220 is twisted, the filtering area per unit space of the twisted filter material 220 increases and the dirt holding performance is improved, thereby improving the filtering performance of the filter element while keeping the size of the filter element unchanged.

[0038] It is understandable that, referring to Figure 1 and Figure 2 When filtering is required, the telescopic frame 210 is rotated to shorten the telescopic frame 210, thereby saving the space occupied by the filter element and improving the dirt holding performance of the filter material 220; when the filter material 220 needs to be cleaned, the telescopic frame 210 is rotated to extend the telescopic frame 210, thereby straightening the outer surface of the filter material 220 to facilitate liquid to flush the stains on the outer surface of the filter material 220.

[0039] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The upper end of the telescopic frame 210 is fixedly connected to a first end cap 241, which is provided with a water outlet pipe 231 extending in the vertical direction. The lower end of the telescopic frame 210 is fixedly connected to a second end cap 242, which is provided with a sewage discharge pipe 232 extending in the vertical direction. The upper end of the filter material 220 abuts against the first end cap 241, and the lower end of the filter material 220 abuts against the second end cap 242. When the telescopic frame 210 contracts or extends, the telescopic frame 210 can cause the filter material 220 to distort due to friction.

[0040] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The wall of the drain hole 120 is provided with a first through hole 251, and the wall of the drain pipe 232 is provided with a second through hole 252. Figure 2 When the telescopic frame 210 is rotated to extend the telescopic frame 210, the first through hole 251 and the second through hole 252 cooperate to connect the sewage pipe 232 with the inner cavity of the filter bottle 100, and the liquid in the filter bottle 100 can pass through the first through hole 251 and the second through hole 252 in sequence and enter the sewage pipe 232. Figure 1 When the telescopic frame 210 is rotated to shorten the telescopic frame 210 , the first through hole 251 and the second through hole 252 are separated to isolate the sewage pipe 232 from the inner cavity of the filter bottle 100 , and the liquid in the filter bottle 100 cannot be discharged through the sewage pipe 232 .

[0041] Preferably, multiple sealing rings are provided on the outer peripheral wall of the sewage pipe 232, and the sealing rings fit tightly with the hole wall of the sewage hole 120 to prevent the liquid in the filter bottle 100 from overflowing through the gap between the hole wall of the sewage hole 120 and the outer peripheral wall of the sewage pipe 232.

[0042] According to some embodiments of the present invention, referring to Figures 1 to 4The telescopic frame 210 includes a first frame 261 and a second frame 262 . The first frame 261 is located above the second frame 262 . The second frame 262 is connected to the first frame 261 . The second frame 262 can be rotated up or down relative to the first frame 261 .

[0043] Preferably, refer to Figure 3 and Figure 4 The outer wall of the first skeleton 261 is provided with a guide hole 271, and the inner wall of the second skeleton 262 is provided with a protrusion 272. When the first skeleton 261 and the second skeleton 262 are connected, the protrusion 272 is located in the guide hole 271. The protrusion 272 can move along the extension direction of the guide hole 271 to drive the second skeleton 262 to rotate up or down relative to the first skeleton 261.

[0044] It can be understood that when the second skeleton 262 rotates up or down relative to the first skeleton 261, since the filter material 220 is simultaneously mounted on the second skeleton 262 and the first skeleton 261, the outer surface of the second skeleton 262 rubs against the inner surface of the filter material 220. When the second skeleton 262 rotates, it will apply a torsional force to the filter material 220, causing the outer surface of the filter material 220 to be twisted and form a spiral shape.

[0045] It should be noted that the first frame 261 and the second frame 262 can also be connected by a threaded connection. For example, the inner peripheral wall of the first frame 261 is provided with an internal thread, and the outer peripheral wall of the second frame 262 is provided with an external thread. When the second frame 262 is rotated to be screwed into the first frame 261, the telescopic frame 210 contracts; when the second frame 262 is rotated to be screwed out of the first frame 261, the telescopic frame 210 extends.

[0046] Preferably, refer to Figure 3 and Figure 4 The guide hole 271 extends circumferentially around the axis of the first skeleton 261, and one end of the guide hole 271 is higher than the other end of the guide hole 271. That is, when the protrusion 272 moves along the extension direction of the guide hole 271, since one end of the guide hole 271 is higher than the other end of the guide hole 271, the second skeleton 262 can rise or fall relative to the first skeleton 261, thereby causing the telescopic skeleton 210 to extend or contract.

[0047] Preferably, refer to Figure 3 and Figure 4 The upper and lower ends of the guide hole 271 are connected with positioning holes 273, which extend in the horizontal direction. The positioning holes 273 can limit the movement of the protrusion 272. For example, when the protrusion 272 moves to the upper end of the guide hole 271, the second skeleton 262 is rotated so that the protrusion 272 enters the positioning hole 273, thereby preventing the protrusion 272 from automatically falling back due to the action of gravity.
