Aquarium filter pump impeller with unique blade design
A recently granted patent (Publication Number: US11920607B2) outlines a method for pumping water in an aquarium filter using a unique impeller design. The method involves rotating an impeller with blades that have a non-constant thickness, including a region of smallest thickness at the free edge that increases along the blade. The blades are structured with opposite faces, free edges, and first and second edges, forming an I-shaped cross-section. The patent specifies that the impeller can have no more than four blades, with each blade having protruding straight edges.
Furthermore, the patent details variations of the impeller design, emphasizing the configuration of at least three blades radially extending from a shaft. These blades are characterized by a non-constant thickness, with a region of smallest thickness at the free edge that increases towards the shaft. The impeller blades are aligned along a plane containing the longitudinal axis of the shaft, with straight edges protruding outwardly. The patent highlights the importance of the unique blade design in efficiently drawing water into the aquarium filter. The patent also specifies that the impeller blades are structured to ensure optimal water flow and filtration efficiency in aquarium systems.
