摘要： An outlet device includes an electronic outlet mode and a mechanical outlet mode. The outlet device has a mechanical outlet control device, an electronic outlet control device and a central control module. The central control module comprises a first outlet passage controlled by the mechanical outlet control device, a second outlet passage controlled by the electronic outlet control device, and a central controller. The first outlet passage includes a sensor and the second outlet passage includes an electromagnetic valve. When the mechanical outlet control device controls the first outlet passage to open, the sensor detects water flowing in the first outlet passage, whether the electromagnetic valve opens or not, the central controller switches the electromagnetic value to a normal closed state.

摘要： An automatically resettable press-type switching valve includes a valve housing, an operating portion, a driven rod, a water blocking member, and a resetting member. The valve housing is formed therein with an inlet and outlet passages. A water blocking seat is provided between the inlet and outlet passages. The operating portion drives the driven rod to move axially so as to form a forward pressure difference or reverse pressure difference between two opposing sides of the water blocking member, by which the water blocking member is pushed to move axially with the driven rod. The resetting member is drivingly connected with the water blocking member, when there is no water pressure at a side of the inlet passage, the resetting member drives the water blocking member to separate from the water blocking seat, and the inlet passage is communicated with the outlet passage.
