(2) Referring to fig. 10, when a user waves the sensing device 3, the sensing device 3 transmits a signal to the receiving device 4, the receiving device 4 transmits the signal to the solenoid valve 1, the solenoid valve 1 is opened, the sealing diaphragm 13 is separated from the sealing surface of the sealing valve seat 14 (i.e., the communication position between the first waterway 114 and the second waterway 115), and water can flow from the first inlet 111 to the first drain opening 113, so that the sensing drainage passage is conducted, and the purpose of touch-free sensing drainage is achieved.
