Embodiment Construction

[0035] figure 1 The vacuum cleaner 1 comprises a handheld unit 2 attached to a cleaner head 4 by an elongated tube 3 . The elongated tube 3 is detachable from the handheld unit 2 so that the handheld unit 2 can be used as a standalone vacuum cleaner.

[0036] now refer to Figure 2 to Figure 7 , the handheld unit 2 includes a dirt separator 10 , a pre-motor filter 11 , a vacuum motor 12 and a post-motor filter 13 . A pre-motor filter 11 is located downstream of the dirt separator 10 but upstream of the vacuum motor 12 and a post-motor filter 13 is located downstream of the vacuum motor 12 . During use, the vacuum motor 12 draws dirt laden fluid through the suction opening on the underside of the cleaner head 4 . From the cleaner head 4 , dirt laden fluid is drawn along the elongate tube 3 and into the dirt separator 10 . The dirt is then separated from the fluid and retained in the dirt separator 10 . Cleaned fluid exits the dirt separator 10 and is drawn through a pre-mo...

Abstract

A handheld vacuum cleaner comprising a dirt separator. The dirt separator comprises a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits thechamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes.

Description

technical field [0001] The present invention relates to a hand-held vacuum cleaner. Background technique [0002] Handheld vacuum cleaners can include filters or cyclones as the primary means of removing dirt. However, both types of separators have their disadvantages. For example, filters typically have poor separation efficiency, while cyclone separators can consume high pressures. Contents of the invention [0003] The present invention provides a handheld vacuum cleaner comprising a dirt separator comprising a chamber having an inlet through which dirt laden fluid enters the chamber, and an outlet, Cleansing fluid exits the chamber through the outlet; and a disc located at the outlet, the disk being arranged to rotate about the axis of rotation and including an aperture through which the washed fluid passes. [0004] Dirt-laden fluid entering the chamber comes into contact with the rotating disk, thereby exerting a tangential force on the fluid. As the dirt-laden f...
