AIR SUPPLY DEVICE AND RELATED METHODS OF MANUFACTURE

摘要

A pump device is provided including: a unitary pump frame; an electromagnet arrangement that includes a winding wrapped around a portion of the unitary pump frame; a diaphragm assembly coupled to the unitary pump frame, which includes a movable diaphragm and a manifold; and a pump arm having a proximal end coupled to the unitary pump frame and a distal end supporting a permanent magnet to interact with the electromagnet arrangement to cause the pump arm to swing back and forth during operation to displace the diaphragm and discharge an air stream from the pump device. Related methods of manufacture are also provided.

1. An air pump comprising:
a unitary pump frame having a bobbin portion integrally formed with a remainder of the unitary pump frame; an electromagnet arrangement including a winding wrapped directly around the bobbin portion of the unitary pump frame such that at least a portion of the winding is in direct contact with the bobbin portion of the unitary pump frame; a diaphragm assembly coupled to and supported by the unitary pump frame, the diaphragm assembly including a movable diaphragm and a manifold; and a pump arm having a proximal end and a distal end, the proximal end of the pump arm coupled to the unitary pump frame and the distal end of the pump arm including a magnet to interact with the electromagnet arrangement to cause the pump arm to swing back and forth to displace the movable diaphragm during operation of the air pump.
