Outlet switch device and an outlet switch method

An outlet switch device, comprising:

• a fixed unit,
• an outlet switch mechanism,
• an inlet switch mechanism, and
• a driving mechanism, wherein
• switching of the outlet functions is realized by relative rotation between the outlet switch mechanism and the fixed unit;
• the fixed unit includes a control cavity and an inlet waterway to connect to an external water source;
• the outlet switch mechanism includes a switch plate,
• the switch plate is movably connected inside the control cavity;
• an elastic piece is disposed between the switch plate and the fixed unit, the elasticity of the elastic piece making the switch plate move forwards;
• wherein
• the inlet switch mechanism controls the inlet waterway to make the water flow into the control cavity, the water flowing into the control cavity making the switch plate compress the elastic piece and move backwards;
• and
• the driving mechanism exerts force on the switch plate and the fixed unit to transform the motion up and down of the switch plate to rotation.
