An optical lens including a lens barrel, a fixing ring, and at least one lens element is provided. A bonding surface is provided on an inner side of a periphery of an end of the lens barrel, and a plurality of micro-structures are disposed on the bonding surface in a ring-shaped arrangement. The micro-structures protrude from the bonding surface. The fixing ring is disposed inside the bonding surface of the lens barrel. The lens element is disposed inside the lens barrel. The micro-structures on the bonding surface and the fixing ring are dissolved by a solvent, so as to fix the lens element inside the lens barrel. An assembling method of the optical lens and a lens barrel are also provided.

Vacuum cleaner

Upright vacuum cleaner

A vacuum cleaner includes a circuit breaking control device responsive to the correct positioning of a dust collecting bag in order to ensure that the vacuum cleaner is not operated without the dust collecting bag. A visible light may be provided to signal that, although the vacuum cleaner main power switch is on, the motors in the vacuum cleaner are not energized because the dust collecting bag is not in place.

A clutch control mechanical device is disclosed for the brush axle of a vacuum cleaner. The clutch control mechanical device is located at the undercarriage of the machine with a pressure control shaft extending out of the inner sides of the undercarriage. At the corresponding position, the underside of the upper body joining the undercarriage is equipped with a pressure control piece so that when the upper body is in a vertical position to the undercarriage, the pressure control piece shall press down on the pressure control shaft of the clutch control mechanical device which suspends rotation of the brush axle. When the upper body is in a slanted angle to the undercarriage, the removal of external force shall return the pressure control shaft to its original position by a spring bias which rotates the brush axle.

A telescopic extension wand of a vacuum cleaner includes an inclined tab provided at the inner wall of a sleeve for biasing a retaining plate having retaining teeth underside to engage with a plurality of retaining teeth of a middle tube or an inner tube so the middle or inner tube can be relatively positioned. A projected boss provided at the inner wall of the sleeve can be guided by a guiding slot disposed at an outer wall of the external tube or middle tube. When the sleeve is rotated to a preset position, the inclined tab as well as the retaining plate can be controlled to engage or disengage the middle tube or inner tube with/without engagement between the retaining teeth therebetween. By this arrangement the middle tube and inner tube can be repositioned.

This invention concerns a Metal Collection Device for Vacuum Cleaners. It consist of a cover structure (that could be opened) that is attached to the soft tube of the vacuum cleaner. The interior of this cover structure has a strong magnet which attracts the metal items sucked in by the vacuum cleaner. This prevents the metal items from entering the main body of the vacuum cleaner and thereby prevents damage to the internal components or to the collection bag. When the need arises to clean or remove the metal items collected by the magnet, the cover structure could be opened and the magnet, along with the metal items collected by it, removed. Thus providing extreme ease of usage.
