Abstract
The invention provides a fluid delivery mechanism and a nutrient pump, the fluid delivery mechanism including a delivery assembly and a connecting base. The delivery assembly includes a flow path and a valve mechanism provided on the flow path, and the delivery assembly is mounted on the connecting base. The fluid delivery mechanism provided by the invention is reliably connected, thereby effectively controlling the fluid conduction or cutoff of the infusion assembly and preventing the occurrence of free-flow phenomenon.
Claims18
A fluid delivery mechanism, comprising:
- a delivery assembly comprising a flow path and a valve mechanism provided in the flow path;
- and
- a connecting base, the delivery assembly being mounted on the connecting base;
- wherein the valve mechanism comprises a valve housing and a valve core removably connected to the valve housing;
- the valve housing comprises an outlet and at least one inlet;
- and
- the valve core includes a hollow structure within the valve core and directly connecting to both a first opening and a second opening that are configured on a circumference of the valve core, and the hollow structure is further in communication with the outlet of the valve housing to provide a fluid passage with the valve housing;
- wherein the valve core is rotatable in a first direction to make one of the first opening and the second opening in communication with one of the at least one inlet, and
- the at least one inlet include a first inlet and a second inlet, and when the valve core is in an initial position, the first opening is configured in line with the first inlet on one side of the outlet, and the second opening is configured in line with the second inlet on the other side of the outlet.
