Secondly, since the detection assembly 3 is arranged in the detection water tank 2, the liquid in the filter water tank 1 is extracted into the detection water tank 2 by the water taking pump 5 for detection, cleaner liquid to be measured can be obtained, the detection assembly 3 is not polluted, the detection assembly 3 is more convenient to maintain and repair, and the water inlet hole on the filter water tank 1 can automatically suck the liquid in the water body to be measured by the negative pressure generated by the water taking pump 5 when pumping water, the water inlet is strengthened by negative pressure, the water inlet efficiency is effectively improved, and the flushing operation of the flushing pump 6 is not blocked.

[0027] Preferably, the self-flushing water quality detection device 1000 further comprises a timing control module (not shown, the same below), the timing control module is electrically connected with the water taking pump 5 and the flushing pump 6 respectively, the timing control module is used to reciprocally switch the timing between a first preset time length and a second preset time length, start the water taking pump 5 and close the flushing pump 6 when in the first preset time length, and close the water taking pump 5 and start the flushing pump 6 when in the second preset time length.
