Odor-removing trap system for cat litter boxes

摘要

An odor-removing trap system for removal of noxious gases emanating from cat litter boxes. The present invention provides an apparatus including an enclosure for capturing, filtering and removing noxious gases associated with cat waste products. Such gases rise upwardly within the enclosure wherein the gases are trapped and drawn from the enclosure. In one embodiment the gases are urged into an exhaust conduit disposed in fluid (i.e. air) transfer communication with the enclosure and flow to the exterior of the building by convection, air pressure or by vacuum created by a brushless fan motor. Such fan motor is powered by a battery pack or, alternatively, is electrically connected to an AC power source and can be actuated automatically by a motion detector whenever a cat enters the enclosure. In alternative embodiments the noxious gases are drawn through an air filter assembly including an activated charcoal filter element and absorbed therein.

主权项

1. An odor-removing trap system for cat litter boxes comprising:
an enclosure assembly including an entry opening, the enclosure assembly further comprising a body member having an airtight gas trap formed therein, wherein the gas trap is defined by a lid member disposed in closing relation to the body member for collecting noxious gases emanating from cat litter contained therein; an outlet port assembly disposed in fluid communication with said enclosure assembly, wherein the outlet port assembly provides a pathway for egress of the noxious gases; a brushless fan motor disposed in fluid communication with the outlet port assembly, wherein the brushless fan motor is integrated within a detachable air filtration assembly including an activated charcoal filter element for absorption of the noxious gases, wherein the air filtration assembly further comprises a timer electrically interconnected to the brushless fan motor, wherein operation of the brushless fan motor is limited to timed intervals, wherein the filtration assembly is disposed externally of the enclosure assembly in fluid communication with the outlet port assembly enabling the noxious gases to be urged from the enclosure assembly; and a motion detector and a light emitting diode disposed remotely from the air filtration assembly within a detachable module positioned in the enclosure assembly, wherein the detachable module is electrically interconnected to the brushless fan motor, the timer and a power source.
