Along with the increase of sundries on the filter plate 25, the waste water discharge speed is reduced, and more waste water is accumulated in the water storage cavity until the water level between the water passing cavity and the water storage cavity is equal to the height. At this time, the waste water gives the filter plate 25 a retraction pressure, and initially, the retraction pressure is not enough to overcome the gravity component of the filter cartridge 2 on the gentle slope section 161 of the adjustment rail 16, the filter cartridge 2 does not retract until the impurities on the filter plate 25 are accumulated to a certain extent, the retraction pressure of the waste water on the filter plate 25 overcomes the gravity component of the filter cartridge 2 on the gentle slope section 161 of the adjustment rail 16, the filter cartridge 2 starts to retract, and the adapter rod 21 moves along the gentle slope section 161 of the adjustment rail 16 and moves the filter cartridge 2 upwards. The filter cartridge 2 is continuously retracted to the end (i.e. the highest end) of the adaptive rod 21 moving to the gentle slope section 161, the partition plate 23 contacts the lower bottom end of the water filling port 15, the water passing cavity and the water storage cavity are blocked, and only the water level in the water passing cavity rises at the moment. The filter plate 25 is still subjected to the retraction force of the waste water to further retract the filter cartridge 2, and as the water level difference between the water passing chamber and the water storing chamber becomes larger, the baffle plate 23 is subjected to a downward pressure from zero and is offset by the supporting force of the horizontal section 162 until the adapter rod 21 moves to the intersection of the horizontal section 162 and the steep slope section 163 of the adjustment rail 16.
Thereafter, because the steep slope section 163 of the adjusting rail 16 is steeper, the filter cartridge 2 expands outward under the combined action of the downward pressure applied to the partition plate 23 and the gravity of the filter cartridge 2, until the adaptive rod 21 moves to the junction between the steep slope section 163 of the adjusting rail 16 and the gentle slope section 161, a cycle is formed, in the process of the cycle, the brush rod 22 brushes the corresponding filter plate 25 twice in the motion of collection and outward expansion of the filter cartridge 2, so that the impurities on the filter plate 25 fall onto the partition plate 23, and fall into the water storage cavity under the pushing of the sweeping plate 24, the blockage is avoided, and the drain outlet 11 can be opened for cleaning after the impurities are accumulated to a certain degree.
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.
