Abstract
Self-cleaning dental suction device comprising a collection tank having an inlet pipe oriented at a downward angle that intersects an interior wall of the tank in a manner to provide a self-cleaning swirling action of liquid waste and solid debris on the interior wall of the tank, a motor operably associated with the collection tank for generating a relative vacuum therein, and a drainage valve communicated to the collection tank for draining the contents of the collection tank. The tank vacuum is discontinued when the tank liquid level reaches a maximum level by a float valve closing off communication between the motor and the collection tank or when the vacuum motor is de-energized.
