[0188] Wherein, the cumulative flushing amount and the instantaneous flushing amount are used to detect whether the valve opening time of the measured pulse electromagnetic valve is normal, the data fusion algorithm can be used to combine the pulse signal output by the flow control plate, the obtained flushing amount and the set valve opening time to detect whether the valve opening time of the measured pulse electromagnetic valve is normal. Other ways can also be used to detect, and the detection method is not limited in the application.

[0189] The embodiments provided by the application control the control module and the second adjusting module to test the flow of the pulse electromagnetic valve, detect the response time and the flow control precision of the measured pulse electromagnetic valve in the set first valve opening time through the instantaneous flushing amount, and ensure the consistency of the performance of the measured pulse electromagnetic valve through the cumulative flushing amount, and also detect the response time and the flow control precision of the measured pulse electromagnetic valve. Therefore, the full performance of the pulse electromagnetic valve can be tested, the comprehensiveness, the accuracy and the test efficiency of the pulse electromagnetic valve test are improved, the response speed of the pulse electromagnetic valve is determined, the response efficiency and the service life of the applied flush valve are improved, and the use experience of the user is improved.

[0190] The above is only a specific embodiment of the application, but the protection scope of the application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
