Vacuum assembly with inlet through removable tank

摘要

The disclosed vacuum assembly can be mounted in a vehicle. The motor/fan assembly is positioned above a chassis wall. Lateral flanges on opposed sides of the tank support the tank in generally horizontal sliding motion from a forward position to an elevated rearward position. A rear flange supports the tank as it pivots to a mounted position in which an inlet on a removable lid on the tank communicates with a hose, and an outlet on the lid communicates with the motor/fan assembly. In a removed position, the inlet and outlet are disconnected. Alignment bosses fit in aligned openings when the tank is in the mounted position.

主权项

1. A vacuum assembly that has:
a head unit that houses a motor and an air impeller, and has an impeller opening that leads to the impeller and a pair of parallel, angled, ramp portions; a vacuum hose that connects to a hose opening on the head unit; a tank that is detachable from the head unit and has lateral flanges; a removable lid that is on the tank, and has an inlet and a separate outlet; and a lateral axis upon which the tank tilts with respect to the head unit between (1) a mounted position in which the lateral flanges are spaced above the angled ramp portions, the inlet adjoins and is sealed to the hose opening on the head unit, and the outlet adjoins and is sealed to the impeller opening on the head unit, and (2) a lowered position in which the lateral flanges rest on the angled ramp portions, requiring the tank to be moved laterally to be fully removed from the head unit, in which tilting the tank from the mounted position to the lowered position lowers the lateral flanges onto the angle ramp portions and simultaneously separates the inlet on the tank from the hose opening and the outlet on the tank from the impeller opening, breaking both the seal between the inlet and the hose opening and the seal between the outlet and the impeller opening.
