When in use, sewage sequentially passes through the water permeable hole 27, the filter screen 7 and the drainage channel 3, then enters the water seal groove 25 to form water seal, overflows and flows into the drainage pipeline from the drainage port 111. When sewage is blocked above the filter screen 7, the sewage cannot be discharged in time, so that the gravity above the filter screen 7 is gradually increased, the filter element 2 overcomes the elastic force of the return spring to move downwards and drives the water guide transmission rod 17 to move downwards, the jacking block 16 which is in jacking fit with the elastic claw 172 at the lower end of the water guide transmission rod 17 moves downwards, the jacking block 16 extrudes the wedge block 15, the wedge block 15 moves inwards, the elastic hook 18 is extruded out of the limiting groove 14, and the elastic hook 18 is in an unlocking state. The top press block 16 moves downwards, then the water discharge hole 162 enters the limiting groove 14, sewage enters from the water inlet 171 of the water guide transmission rod 17 and flows downwards along the water guide transmission rod 17, the sewage flows into the water discharge channel 3 from the water discharge hole 162 and the guide channel 161 of the top press block 16 which are in top press fit with the elastic claw 172, when the gravity above the strong spring 13 is smaller than the elastic force of the strong spring 13, the filter element 2, the filter plug 5, the filter screen 7, the fixed seat 28, the fixed rod 12, the first magnetic retainer ring 8, the second magnetic retainer ring 35 and the elastic hook 18 all ascend under the elastic force of the strong spring 13 until the elastic hook 18 is clamped into the limiting groove 14 of the upper layer, at the moment, the ascending distance of the filter element 2 just enables one water inlet groove 4 to be located above the stopping table 6, the sewage enters from the water inlet groove 4, and the ascending distance of the filter element 2 just enables one first magnetic retainer ring 8 to be separated from the first limiting rod 10, the separated first magnetic check ring 8 drives the steel wire 23 to rotate under the action of magnetic force, so that the filter plug 5 moves inwards along the water inlet groove 4 to make the filter holes 20 clear, and the water passing amount is increased. When the sewage is blocked again in the water inlet grooves 4, the working process is the same as before until all the water inlet grooves 4 are exposed above the stopping table 6, and the magnetic driving type anti-blocking sewage drainage floor drain is adjusted again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
