Abstract
A cleaning device includes a grip comprising a fan, a battery, and a switch configured to power the fan; a pole having a proximal end coupled to the grip and a distal end, the pole defining a first internal channel in fluid communication with the fan; and a head portion coupled to the distal end of the pole and including an articulating hinge defining a second internal channel aligned with the first internal channel and an aperture. The fan is configured to draw air from the grip through the first and second internal channels and expel it through the aperture to dislodge friction inhibiting debris.
Claims20
1) A cleaning device, comprising:
- a grip comprising a fan, a battery, and a switch;
- wherein the battery is configured to power the fan via the switch;
- a pole having a proximal end coupled to the grip and a distal end, wherein the pole defines a first internal channel configured to receive air from the fan;
- and
- a head portion comprising:
- an articulating hinge that defines a second internal channel configured to communicate air with the first internal channel, an aperture configured to communicate air with the second internal channel;
- wherein the head portion is coupled to the distal end of the pole;
- the fan is configured to communicate air from the grip, through the first internal channel to the second internal channel of the articulating hinge, and out through the aperture.
11) A method of cleaning a climbing surface, the method comprising:
- providing a cleaning device comprising:
- a pole having a proximal end coupled to a grip comprising:
- a fan, a battery, a switch, and a printed circuit board, wherein the battery is configured to power the fan via the switch and the printed circuit board;
- and a first internal channel configured to internally pass air from the proximal end to a distal end of the pole;
- the distal end being configured to couple with an articulating hinge that defines a second internal channel configured to communicate air with the first internal channel;
- and a head portion coupled to the articulating hinge, the head portion comprising an aperture configured to communicate air with the second internal channel, wherein the cleaning device is configured such that the fan communicates air from the grip, through the first internal channel of the pole, through the second internal channel of the articulating hinge, and out through the aperture to dislodge dust particles;
- and
- affixing a brush into a slot on the head portion of the cleaning device;
- activating the fan by actuating the switch, thereby causing the fan communicate air through the first internal channel, through the second internal channel, and out of the aperture;
- and
- directing head and the brush toward the climbing surface to dislodge debris therefrom.
20) A cleaning device, comprising:
- a head portion comprising an aperture and configured to removably accommodate a brush;
- and
- an air delivery system comprising a grip configured to communicate with the head portion;
- wherein the grip and the head portion together define an enclosed airway in communication with the aperture via the air delivery system.
