ABSTRACT:
An air pump includes: a pump mounted within a housing, a silencer attached to the pump for reducing vibrational shock of the operating pump and for reducing noise by directing the discharged compressed air into the silencer, a heater secured in a heat-exchange chamber in the silencer for heating the discharged air for warming the outlet air with the heater mounted in the silencer well sealed for preventing heat loss, and a suction hood detachably mounted on a side panel of the housing having filter provided in the suction hood for removing dirts laden in the suction air stream, whereby upon dismantling of the suction hood, the hose connected to the sacs of an air mattress may be instantly connected to an inlet adapter of a suction tube connected to the pump for immediately sucking and exhausting air in the sacs for descending the air mattress for an emergency CPR (cardiopulmonary resuscitation).
