Patent ID: 8734135

Claim:
An electric air pump comprising: a pumping assembly having a casing having an open top having a top annular edge; a bottom; an outer surface; and a cavity defined in the casing and communicating with the open top; an outer bracket connected pivotally to the pumping assembly and having a faceplate mounted pivotally on the open top of the casing of the pumping assembly and selectively hermetically contacting the top annular edge of the open top of the casing; an opening defined through the faceplate and having an inner annular edge; and a locking member formed on the inner annular edge of the opening and having a locking hole defined through the locking member; and an inlet plate mounted securely in the open top of the casing, located between the casing and the outer bracket and having multiple inlet holes defined through the inlet plate and communicating with the cavity of the casing; and a resilient locking hook formed on and protruding upward from the inlet plate and selectively hooking in the locking hole of the locking member of the outer bracket, wherein: when the resilient locking hook hooks in the locking hole of the locking member of the outer bracket, the faceplate hermetically contacts the top annular edge of the open top of the casing; and when the resilient locking hook is pulled and released from the locking hole of the locking member of the outer bracket, the outer bracket pivots up relative to the casing and the faceplate separates from the top annular edge of the open top of the casing to form an air exhaust gap therebetween.
