DUST-COLLECTING DEVICE OF VACUUM CLEANER (VERSIONS) Russian patent published in 2009 - IPC A47L9/10 

Abstract RU 2374977 C2

FIELD: personal demand items.

SUBSTANCE: dust-collecting device is used in vacuum cleaner and comprises dust-separating device for separation of contaminating particles from air, dust-collecting vessel, having compartment for accumulation of contaminating particles separated in dust-separating device, which is selectively installed in dust-collecting vessel, and separating element, which separates internal space of dust-separating device from internal space of compartment for accumulation of contaminating particles and selectively opens and closes dust-separating device. Separating element contains hole for discharge of contaminating particles into compartment for accumulation of contaminating particles and is connected to dust-separating device. In version of design, dust-collecting device comprises dust-collecting vessel with compartment for accumulation of contaminating particles and dust-separating device, which is selectively installed inside dust-collecting vessel and separates contaminating particles from air. Dust-separating device is connected to cover joined to dust-collecting vessel, which selectively opens and closes it. Inside dust-separating device there is a filtering element connected to cover. Vacuum cleaner comprises the main vessel, on which dust-collecting vessel is installed with the possibility of detachment, having compartment for accumulation of contaminating particles. In dust-collecting vessel there is a selectively installed dust-separating device, which separated contaminating particles from air. Vacuum cleaner has guide device for guiding of dust-separating device in process of installation. Guide device comprises the first guide element, which protrudes outside from dust-separating device, and the second guide element, which is created on dust-collecting vessel holding the first guide element and arranged as corresponding to the first guide element.

EFFECT: improved efficiency of contaminating particles separation and prevention of reverse flow of collected contaminating particles into dust-separating device.
