TODAY’S PATENT – HAND CARRIABLE SURFACE CLEANING APPARATUS

The Hand carriable surface cleaning apparatus was invented by Wayne Ernest Conrad and is been patented by USPTO on 25^th September 2018 bearing patent no. US10080472B2. This patent has been assigned to Omachron Intellectual Property Inc.

A hand surface cleaning apparatus can operate for longer without reducing airflow into the dirty air inlet. This device has a transversely enhanced pre-motor filter. HEPA pre-motor filters reduce entrained dirt. Use clogs the filter. The lifespan of a pre-motor filter and a post-motor filter can be extended by increasing its upstream side surface area. Configuring the pre-motor filter with a larger upstream surface area than the suction motor inlet end increases its surface area.

The pre-motor filter can cover the cyclone chamber, suction motor, dirt collection chamber, or part of the open volume between them. The hand surface cleaning device has a suction motor, cyclone chamber, pre-motor filter, and an openable door. When the door is opened, the pre-motor filter may remain attached to at least one cyclone chamber and the suction motor.
