The specific working process is as follows:
when the water quality detector works continuously, if a detected water sample at the last time is not cleaned up, the next detection result is easily influenced; therefore, the invention is provided with the flushing module 4; the detector is used for detecting the pH value of a water sample; in an initial state, the flushing plate 44 is positioned at the upper end of the inner shell 41, clean water is firstly introduced into the flushing plate 44 through the water inlet 45, when the clean water fills the space between the flushing plate 44 and the upper end part of the inner shell 41, the controller controls the electric push rod 43 to push the flushing plate 44 downwards, and the clean water on the flushing plate 44 flushes the inner shell 41 from top to bottom; when the flushing plate 44 is pushed to the lower end of the inner shell 41, the flushed clean water flows out through the first water outlet 46; then the electric push rod 43 drives the flushing plate 44 to restore the initial state, a detection water sample is introduced into the flushing plate 44 through the water inlet 45, and when the detection water sample fills the space between the flushing plate 44 and the upper end part of the inner shell 41, the controller controls the electric push rod 43 to push the flushing plate 44 downwards, so that the detection water sample on the flushing plate 44 washes away the residual clear water on the inner shell 41; when the washing plate 44 is pushed to the lower end of the inner case 41, the test water sample for washing flows out through the first water outlet 46; then the electric push rod 43 drives the washing plate 44 to move upwards to the position of the first water outlet 46, so that the first water outlet 46 is blocked by the washing plate 44, a detection water sample is introduced into the inner shell 41 through the water inlet 45, and substances in the detection water sample are detected through the sensor 3, wherein the sensor 3 is a pH sensor; after the detection is finished, the electric push rod 43 pushes the washing plate 44 downwards again, so that the detected water sample flows out through the first water outlet 46; compared with the traditional technical scheme, the detection water sample detected in the previous time is not cleaned, so that the accuracy of experimental data is influenced; because the washing plate 44 is arranged, the detection water sample at the previous time is washed clean by using a small amount of clear water and the detection water sample, so that the accuracy of each detection data is ensured; after the detection water sample is introduced, the situation that substances precipitate in the detection water sample can be generated, so that detection data can be influenced; therefore, by arranging the rotating module 5, when the flushing plate 44 moves to the lower end of the inner shell 41, the flushing plate 44 is completely clamped with the driving motor 51, when the flushing plate 44 moves upwards to block the upper end of the first water outlet 46, the lower end of the flushing plate 44 is clamped with the driving motor 51, and then a detected water sample is introduced into the inner shell 41 to start detection, the controller controls the driving motor 51 to drive the inner shell 41 and the flushing plate 44 to rotate, and at the moment, the flushing plate 44 is positioned at the upper end of the first water outlet 46 to block the first water outlet 46, so that the detected water sample cannot be easily precipitated due to a long-time static state in the introducing process; after the detection is finished, the detection water sample flows into a cavity formed by the enclosing plate 53, the inner shell 41 and the outer shell 52 through the first water outlet 46 and flows out through the second water outlet 54; the inner shell 41 is driven to rotate by the driving motor 51, so that the accuracy of the detection result of the water quality detector is improved; because the balls 6 are embedded in the outer ring of the flushing plate 44, the sliding friction between the flushing plate 44 and the inner shell 41 is converted into rolling friction, and the friction force is reduced, so that the flushing plate 44 can move on the inner shell 41 more smoothly;
