Abstract: A vortex flush toilet includes a toilet stool including a toilet bowl and a rim unit, a water tank unit, a first water discharge unit, a pipe unit, an electric switching valve, and a sensor control unit controlling switching of the electric switching valve between a blocked state and a communicated state. The rim unit is formed with first, second, and third flushing ports having decreasing sectional area, and has first, second, and third water-guiding passages respectively in fluid communication with the first, second, and third flushing ports and each having a width decreasing gradually. A bottom surface of each of the first, second, and third water-guiding passages has a height decreasing gradually and forms a respective one of first, second, and third height differences increasing gradually. An inclination angle defined between the bottom surface of each first, second, and third water-guiding passage and a horizontal line gradually increases.

Abstract: An electric valve includes a valve member switchable between a closing state to close a flow passageway of a valve body and an opening state to open the passageway. An adaptor is connected to the valve member. A motor drives rotation of a rotation shaft connected to the adaptor. A circuit board is electrically coupled to the motor and a backup battery pack. A microprocessor control unit is electrically coupled to the circuit board. The motor drives the valve member through the rotation shaft and the adaptor to switch between the opening and closing states. The microprocessor control unit controls a time delay for switching the valve member from the opening state to the closing state.
