Abstract
Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, the cover prevents debris from leaving the collection chamber through the inlet opening. The wall of the collection chamber moves when negative pressure is applied to the collection chamber, and the wall movement moves the cover from the inlet opening, allowing the debris-entrained air to enter the collection chamber. In some embodiments, the moving part of the wall is an air filter.
Claims19
An apparatus comprising:
- a debris collection chamber having a bottom and a top, wherein the chamber top is movable relative to the chamber bottom;
- an air filter configured to allow air to pass through the air filter while inhibiting debris from passing through the air filter;
- a collection chamber inlet opening configured to allow debris-entrained air to flow into the collection chamber;
- wherein the air filter forms at least a portion of the movable chamber top, and is movable from a first position, in which the air filter covers the chamber inlet opening, to a second position in which the air filter does not cover the chamber inlet opening
- wherein the air filter is adapted to be moved to the second position when negative pressure is applied to the air filter to draw air through the chamber inlet opening.
An apparatus adapted to be attachable to a vacuum cleaner, the apparatus comprising:
- a debris collection chamber having a bottom and a top, wherein the chamber top is movable relative to the chamber bottom;
- a collection chamber inlet opening configured to allow debris-entrained air to flow into the debris collection chamber;
- an air filter forming at least a portion of the movable chamber top, and configured to allow air to pass through the air filter while inhibiting debris from passing through the air filter;
- a cover movable from a first position in which the cover covers the chamber inlet opening, to a second position in which the cover does not cover the chamber inlet opening;
- wherein the cover is attached to the air filter, and the air filter is arranged such that when the air filter is under no negative pressure, the cover is in the first position, and the air filter is arranged such that when negative pressure is applied to the air filter to draw air through the chamber inlet opening, the air filter moves the cover to the second position.
An apparatus adapted to be attachable to a cleaning device having a suction source, the apparatus comprising:
- a debris collection chamber having a bottom and a top, wherein the chamber top is movable relative to the chamber bottom, and having a chamber wall that moves when negative pressure is applied to the collection chamber;
- a collection chamber inlet opening configured to allow air to flow into the debris collection chamber when negative pressure is applied to the debris collection chamber;
- a cover forming at least a portion of the movable chamber top, and movable from a first position, in which the cover covers the chamber inlet opening, to a second position in which the cover does not cover the chamber inlet opening;
- wherein the cover is attached to the chamber wall and arranged such that when the chamber wall moves due to the negative pressure being applied the collection chamber, the chamber wall moves the cover from the first position to the second position in which the cover does not cover the chamber inlet opening, and a flow path is opened for debris-entrained to be drawn into the collection chamber through the chamber inlet opening.
