Abstract

A vacuum cleaning device comprises: a housing; a motor and fan assembly for generating an airflow between an air inlet and an air outlet. A removable dirt collection bin receives dirt in the airflow. The dirt collection bin is located in fluid communication between the air inlet and air outlet and mountable to the housing. A locking mechanism is moveable between a locked position and an unlocked position for releasably coupling the dirt collection bin to the housing. An ejection mechanism arranged to eject the dirt collection bin away from the housing when the locking mechanism is in the unlocked position.

First claim

The invention claimed is:

1. A vacuum cleaning device comprising:
a housing defining a chamber;
a motor and fan assembly located inside the housing for generating an airflow between an air inlet and an air outlet;
a removable dirt collection bin for receiving dirt in the airflow, the dirt collection bin being located in fluid communication between the air inlet and air outlet and mountable within the housing chamber;
a locking mechanism moveable between a locked position and an unlocked position for releasably coupling the dirt collection bin to the housing;
an ejection mechanism arranged to eject the dirt collection bin away from the housing when the locking mechanism is in the unlocked position;
wherein the ejection mechanism is arranged to urge the dirt collection bin from a coupled position in which the dirt collection bin is lockable with the housing to a decoupled position in which the dirt collection bin projects out from the housing; and
wherein the housing comprises a gripping element which increases friction between the dirt collection bin and the housing when the dirt collection bin is in the decoupled position.

2. The vacuum cleaning device according to claim 1 wherein the ejection mechanism comprises at least one projecting arm engageable with a reciprocal recess in the dirt collection bin.

3. The vacuum cleaning device according to claim 1 wherein the ejection mechanism comprises a biasing member urging the dirt collection bin away from the housing.

4. The vacuum cleaning device according to claim 1 wherein the housing has a longitudinal axis parallel with an air inlet nozzle; and
the dirt collection bin is releasably coupled to the housing such that the dirt collection bin is moveable in a direction substantially transverse to the longitudinal axis.

5. The vacuum cleaning device according to claim 1 wherein the housing comprises a handle and the dirt collection bin is mountable between the handle and the housing.

6. The vacuum cleaning device according to claim 1 wherein the locking mechanism comprises a first latch portion and a second catch portion.

7. The vacuum cleaning device according to claim 6 wherein the first latch portion comprises a plurality of moveable hook elements and the second catch portion comprises a plurality of corresponding reciprocal fixed hook elements.

8. A vacuum cleaning device comprising:
a housing defining a chamber;
a motor and fan assembly located inside the housing for generating an airflow between an air inlet and an air outlet;
a removable dirt collection bin for receiving dirt in the airflow, the dirt collection bin being located in fluid communication between the air inlet and air outlet and mountable within the housing chamber;
a locking mechanism moveable between a locked position and an unlocked position for releasably coupling the dirt collection bin to the housing;
an ejection mechanism arranged to eject the dirt collection bin away from the housing when the locking mechanism is in the unlocked position;
wherein at least part of the locking mechanism is mounted on a moveable ring member, and the moveable ring member is mounted on the dirt collection bin; and
wherein the dirt collection bin comprises a substantially circular cross section and the moveable ring member is rotatable around the longitudinal axis of the dirt collection bin.

9. The vacuum cleaning device according to claim 8 wherein the at least part of the locking mechanism is mounted on the housing.

10. The vacuum cleaning device according to claim 8 wherein the device comprises an actuating button for actuating the locking mechanism.

11. The vacuum cleaning device according to claim 8 wherein the locking mechanism is biased to the locking position.

12. A vacuum cleaning device comprising:
a housing;
a motor and fan assembly located inside the housing for generating an airflow between an air inlet and an air outlet;
a removable dirt collection bin for receiving dirt in the airflow, the dirt collection bin being located in fluid communication between the air inlet and air outlet and mountable to the housing;
a dirt separation assembly located within the dirt collection bin;
a locking mechanism moveable between a locked position and an unlocked position for releasably coupling the dirt collection bin to the housing, wherein at least part of the locking mechanism is mounted on a moveable ring member; and
an ejection mechanism arranged to eject the dirt collection bin away from the housing when the locking mechanism is in the unlocked position.

13. The vacuum cleaner device of claim 12 wherein the housing has a longitudinal axis parallel with an air inlet nozzle; and
the dirt collection bin is releasably coupled to the housing such that the dirt collection bin is moveable in a direction substantially transverse to the longitudinal axis.
