[0041] According to this embodiment, the present application can effectively filter solid wastes such as slag and stones and temporarily store them in the collection part 32 by setting the filter chamber 12 and the filter cylinder 31 in the filter chamber 12, which can not only prevent solid wastes such as slag and stones from entering the sewer, but also facilitate the removal of the collection part 32 for cleaning. At the same time, the filter element 30 has a certain height, and through the design of the long filter hole 311, when solid wastes such as slag and stones are accumulated around the collection part 32 and the filter cylinder 31, the filter cylinder 31 can still play the role of filtering and draining.

[0042] See attached Figures 1 to 7As shown, in some embodiments, the edge of the water inlet of the filter chamber 12 has a supporting groove 121 extending radially, and the filter end cover 20 is T-shaped, and the filter end cover 20 is placed in the supporting groove 121.

[0043] According to this embodiment, the filter end cover 20 is arranged in this way to facilitate quick disassembly and assembly, thereby facilitating cleaning of the collection portion 32 .

[0044] Refer to the attached Figures 4-5 As shown, in some embodiments, the plurality of elongated filter holes 311 are all spiral-shaped.

[0045] Exemplarily, the spiral long filter holes 311 correspond to the rotation direction of the water flow.

[0064] According to this embodiment, by such an arrangement, the loading capacity of the supporting cylinder 322 can be improved and the cleaning interval time can be increased.

[0065] Specifically, the working principle of the anti-blocking prefabricated floor drain is as follows: when draining water, it is first filtered through the filter end cap 20, and solid waste such as slag and stones will enter the filter chamber 12 with the water flow, and then filtered again through the filter cylinder 31, so that solid waste such as slag and stones are temporarily stored on the collection part 32. At the same time, the sewage will pass through the long filter hole 311 and the filter chamber 12 to be discharged to the drain port 131. At this time, the water flow impacts the blocking plate 42, and the blocking plate 42 can flip around the bracket 41 and open the drain port 131 for drainage.
