Beschreibung
Zusammenfassung:	The invention provides a USB interface circuit for an intelligent toilet pan, comprising a first USB interface circuit arranged on a toilet pan host; The first USB interface circuit comprises a USB mother socket, a boost circuit, a current limiting circuit, an input/output switching relay and a motherboard connector for connecting a host motherboard. The first USB interface circuit comprises a USBmother socket, a boost circuit, a current limiting circuit, an input/output switching relay and a motherboard connector for connecting a host motherboard. 12V pow supply end of that host computer main board is connecte with two ends of the relay coil, when the host computer main board normally supplies pow, the relay communicates the USB mother socket power supply pin with the output end of the current limiting circuit, and the 5V power supply is externally supplied by the USB mother socket after the current is limited; When the mainboard of the host computer is powered off, the relay communicates the USB mother sock
