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 closed perimeter structure which defines a pump assembly cavity and having a bobbin portion integrally formed therewith, the bobbin portion including a hollow core and opposing flanges; an electromagnet arrangement including a winding wrapped directly around the hollow core of the bobbin portion of the unitary pump frame such that at least a portion of the winding is in contact with the unitary pump frame; a diaphragm assembly coupled to and supported by the unitary pump frame within the pump assembly cavity, the diaphragm assembly including a movable diaphragm and a manifold; a pump arm having a proximal end and a distal end, the proximal end of the pump arm coupled to the unitary pump frame to support the pump arm within the pump assembly cavity, 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; and a plurality of flexible, resilient tethers extending from the unitary pump frame for suspending the air pump within an internal cavity of a housing or a host device.
