Abstract

An actuating mechanism includes an actuating shaft, an actuated member, and an engaging and disengaging structure. The actuating shaft is configured to be rotatable. The actuated member can be actuated by the actuating shaft to rotate. The engaging and disengaging structure includes an actuating structure provided on the actuating shaft and an actuated structure provided on the actuated member. When the actuating structure engages with the actuated structure, the actuating structure can drive the actuated structure to rotate, such that the actuating shaft can drive the actuated member to rotate. Further, a set of actuating and actuated structures of the actuating mechanism can rotate and stop according to set angle requirements, such that a valve body can be actuated to connect and disconnect different fluid passages as required.
