VACUUM CLEANER AND HOSE UNIT THEREOF Russian patent published in 2013 - IPC A47L9/28 

FIELD: personal use articles.

SUBSTANCE: proposed is a vacuum cleaner hose unit containing a flexible hose, a manual control tube, connected and interacting with the flexible hose, a handle fixed on the manual control tube and a control panel mounted on the handle. The flexible hose is equipped with multiple electric wires interconnecting the flexible wire ends. The manual control tube contains a cylindrical turning tube positioned at one of the flexible hose ends, a group of ring electrodes (positioned along the turning tube axis and encompassing the outer surface of the turning tube and electrically connected to the said electric wires), an outer housing (covering the group of ring electrodes and supporting the turning tube so that to enable its turning round its axis and a contact unit with electric wires laid through the manual control tube ensuring electric connection of the control panel to the ring electrodes. The contact unit contains the first contact group with multiple contacts positioned close to one end of the group of ring electrodes essentially - in a row on one side of the turning tube and the second contact group with multiple contacts positioned close to the other end of the group of ring electrodes essentially - in a row on the turning tube side opposite to the first contact group.

EFFECT: prevention of the flexible dust collection hose twisting and electric conductance trouble in case of the vacuum cleaner prolonged operation.
