A multi-level waterway control device has: a fixed unit, a flow regulating plate, a function switching plate and a drive unit. Flow regulation is achieved through the relative rotation between the flow regulating plate and the fixed unit. The outlet functions switch is achieved through the relative rotation between the function switching plate and the fixed unit. The drive unit can slide and rotate relative to the fixed unit, at least happen between the first and second position. When the drive unit is at the first position, it can form a synchronous rotation connection with the flow regulating plate, and the drive unit can drive the rotation of the flow regulating plate to achieve flow regulation. In the second position, the drive unit can form a synchronous rotation connection with the function switching plate, can drive the rotation of the function switching plate to achieve outlet functions switch. |

1. A multi-level waterway control device, comprising:
a fixed unit; a flow regulating plate rotationally arranged in the fixed unit, flow regulation being achieved through a relative rotation between the flow regulating plate and the fixed unit, the flow regulating plate having a first inner hole, and an axial first synchronous slot opened on an inner revolution surface of the first inner hole; a function switching plate rotationally arranged in the fixed unit, switching between a plurality of outlet functions is achieved through a relative rotation between the function switching plate and the fixed unit, the function switching plate having a second inner hole, and an axial second synchronous slot opened on an inner revolution surface of the second inner hole; and a drive unit having a sliding and rotation connection relationship with the fixed unit, the sliding occurring at least between a first position of the drive unit and a second position of the drive unit, the drive unit having an open mounting slot, an elastic body and synchronous keys, the elastic body and synchronous keys being mounted in the mounting slot, the synchronous keys being against the elastic body and extending out of the mounting slot, the synchronous keys being adaptive to the first synchronous slot and the second synchronous slot; wherein when the drive unit is at the first position, the drive unit has a synchronous rotation connection relationship with the flow regulating plate, and has a relative free rotation connection relationship with the function switching plate; when the drive unit is at the second position, the drive unit has a synchronous rotation connection relationship with the function switching plate, and has a relative free rotation connection relationship with the flow regulating plate; and when the drive unit is at the first position, the synchronous keys are adaptive to the first synchronous slot, and when the drive unit is at the second position, the synchronous keys are adaptive to the second synchronous slot. |
