Removable top fill tank

摘要

A reservoir system for an operating unit, such as a humidifier, includes a removable water tank configured to provide the operating unit with water. The removable water tank includes a primary reservoir for holding water, with an opening in the removable water tank fluidically connecting the primary reservoir with a secondary reservoir in the operating unit. A plunger is slidably disposed in the opening and movable between an open position in which the opening fluidically connects the primary reservoir to the secondary reservoir, and a closed position that seals the opening to fluidically disconnect the primary reservoir from the secondary reservoir. A float member in the secondary reservoir includes a buoyant main body and is configured to generate a force upon the plunger to urge the plunger into the open position according to the height of water in the secondary reservoir.

主权项

1. A removable tank for an operating unit, the removable tank comprising:
a reservoir for holding water; an opening in the removable water tank configured to allow water to exit from the reservoir; a plunger at least partially movably disposed in the opening, the plunger movable between an open position in which water exits the reservoir and a closed position that seals the opening to prevent water from exiting the reservoir; and a float member movably coupled to the removable tank, the float member comprising:
a buoyant main body configured to generate a force upon the plunger to urge the plunger toward the open position based upon movement of the buoyant main body,a lever coupled to the buoyant main body, andan engaging member connected to and positioned in between the lever and at least a portion of the buoyant main body, the engaging member pivotably securing the float member to a bottom portion of the removable tank, said force generated by the buoyant main body providing a corresponding force to the lever via the engaging member, and the lever being movable to mechanically contact the plunger.
