Embodiment Construction

[0043] figure 1An advantageous arrangement according to the invention is depicted in which the connector 3 facilitates the connection of the suction 9 to an outlet 5 preferably connected to or formed in a surface cleaning device. The distal end of the connector 2 is configured to receive and hold a suction member 9, such as a hose, rod or pipe. The connector 3 comprises a rotatable sleeve member 15 preferably comprising a first outer section 13 and a second outer section 11, wherein the first section 13 has a reduced diameter. In a preferred configuration of the invention, the first outer section 13 acts as a handle which can be grasped by the user. The rotatable sleeve member 15 is rotatable about the longitudinal axis 6 of the connection arrangement. The annular shape of the connector 3 allows the connector 3 to be rotated around the outlet 5 while the connector 3 is connected to the outlet 5 .

Abstract

A connector for connecting a suction member to a surface cleaning apparatus, the connector comprising a tubular body having a distal end configured to receive and retain the suction member and a proximal end configured to receive an outlet of the apparatus; wherein the tubular body is provided with an external rotatable sleeve member; wherein the rotatable sleeve member is provided with at least one projection configured to engage a corresponding formation of the outlet of the apparatus and form a rotatable snap-fit connection between the connector and the outlet; and at least one electrical connection ring located about the proximal end of the connector configured to contact at least one corresponding electrical connector of the outlet to transmit electrical power from the apparatus to the suction member.

Description

technical field [0001] The present invention relates generally to surface cleaning appliances, such as vacuum cleaners, and in particular to a connector for connecting a suction member to a suction cleaning appliance. Background technique [0002] Vacuum cleaners are well known electrical appliances that use a suction airflow to suck dust and other matter away from objects to be cleaned. The airflow passes through a dust separator and collector, where the dust entrained in the suction airflow is separated from the airflow and retained for subsequent processing. For effective cleaning, high velocity airflow is required. To generate high-speed airflow, the vacuum cleaner needs a powerful suction source in the form of a fan or impeller capable of generating strong airflow and a corresponding powerful motor to drive the fan. [0003] Many vacuum cleaners are provided with a suction member, such as a flexible hose or wand, connected to the vacuum cleaner. The attachment of the...
