Abstract:
1. A vacuuming device, wherein said device comprises: a primary chamber, having an interior for the deposit and collection of debris, with at least one first ingress opening for ingress of air and debris and at least one second opening for the extraction of air and entrained debris from the primary chamber; a fan connected to a power source, which turns the fan to create a vacuum within said primary chamber by extracting air from within said primary chamber through the at least one second opening; a fan plate positioned between the fan and the primary chamber, said fan plate having one or more openings through which air and entrained debris, extracted from the primary chamber, passes before reaching the fan; a filter hopper affixed over the fan plate, such that the filter hopper and fan plate form a hollow chamber, the filter hopper further comprising at least one opening contiguous with the second opening in the primary chamber through which air and all entrained debris from the primary chamber enters before passing through the one or more openings in the fan plate; a fan housing disposed over the fan such that the fan is enclosed by the fan housing and the fan plate; a filter duct, in the primary chamber, contiguous with the opening in the filter hopper and comprising a primary filter through which air and entrained debris from the primary chamber pass prior to entering the filter hopper; a secondary chamber, having an interior that is separated from the primary chamber, and an exhaust air filter therein; and a connection duct having first and second openings, said first opening being connected to the fan housing and said second opening being connected to the secondary chamber, such that air and entrained debris from the fan housing pass through the connection duct into the secondary chamber where the entrained debris settles and air exits the device through the exhaust air filter.
