Filtering system in multi-channel circulating water control system

A filtering system in a multi-channel circulating water control system comprises a filtering base and a filtering cover body, the filtering cover body can cover the filtering base to form an inner cavity, a water inlet connector is formed in the filtering cover body, and a water drainage connector is formed in the lower end of the filtering base; the filter element is arranged in the inner cavity; a pressing plate assembly is further arranged in the inner cavity and comprises a partition plate and a pressure spring, the pressure spring is located between the filtering base and the filtering cover body and divides the inner cavity into an upper buffering cavity and a lower filtering cavity, a through hole is formed in the partition plate, and the pressure spring abuts against the position between the filtering cover body and the partition plate and enables the partition plate to always have the downward pressing movement trend. And the partition plate is propped against the upper end of the filter element. The
