Flow detection circuit of direct water dispenser

The invention relates to the field of home direct water dispensers, particularly to a flow detection circuit of a direct water dispenser. The flow detection circuit comprises an alarm display interface terminal Display_P1, a single-chip microcomputer STC10F08XE, a power supply circuit, a crystal oscillation circuit, an EEPROM (Electrically Erasable Programmable Read-Only Memory) storage circuit and a water flow sensor interface P2 terminal. According to the flow detection circuit of the direct water dispenser, the actual use state of every filter element can be effectively detected so as to enable a user can timely replace the filter element which needs to be replaced.
