And controlling the normally closed end of the sampling three-way electromagnetic valve 9 to be communicated with the excrement collecting hose. And controlling the normally closed end of the sample adding three-way electromagnetic valve 10 to be communicated with the excrement sample adding needle.
The motor driver controls the direct current peristaltic pump 11 to rotate positively to start working, and the direct current peristaltic pump 11 sucks excrement diluted solution in the closestool into the buffer storage pool through a normally closed end of a sampling electromagnetic valve, an excrement sampling hose 2 (located inside the sampling pipe 6) and a sampling filter head 13 which are connected with the hose.
When the liquid level of the buffer pool floats the buoy in the buffer pool and triggers the sample liquid level sensor, the sample liquid level sensor gives a signal to the controller, and the controller sends a signal to the motor driver to stop the motor of the direct current peristaltic pump 11.
The motor driver makes 8 motors of peristaltic sample adding pumps begin to rotate, and the excrement diluted solution in the buffer pool is discharged through the hose, the sample adding three-way electromagnetic valve 10 (a public end and a normally closed end), the hose and the excrement sample adding needle, so that the excrement sample is conveniently titrated and output to be manufactured into an excrement sample detection card.
And after the sample is titrated and output, cleaning the interior of the pipeline.

Running water enters the buffer pool, the buffer pool is filled and cleaned, and water can be introduced into the closestool through the overflow pipe after the buffer pool is filled with water.
The controller sends signals to the motor driver and the DC power supply control panel, so that the motor of the peristaltic sample adding pump 8 keeps rotating in the forward direction and the motor of the DC peristaltic pump 11 rotates in the reverse direction.
When the peristaltic sample adding pump 8 rotates forwards, automatic water in the buffer pool is discharged through the hose, the sample adding three-way electromagnetic valve 10, the hose and the excrement sample adding needle to clean the inside of the excrement sample adding pipeline and flows into the waste liquid box.
