Ventilator adaptor for litter box e.g. for cat

摘要

The adaptor (10) comprises a flat housing (12) with an interior space and a downwardly dependent skirt and seal (46) extending around the lower half. An external duct fitting is located on the upper surface. An internal duct extends upwardly through the lower half, through the interior space and is connected to the external duct fitting located on the upper surface. An electric fan is mounted in the internal duct. The fan rotates and cause air from the container to be pumped upwardly through the internal duct to the external duct. A flexible vent tube (14) is connected to the external duct for delivering the air pumped by the fan to a remote location. When the downwardly dependent skirt is placed over the upper vent location of the container, the adaptor causes air to be removed from the container and to be delivered to the remote location.
