Title:
AIR PUMP FOR A BEDSORE-PREVENTING MATTRESS
Document Type and Number:
WIPO Patent Application WO/2012/029999
Kind Code:
A1
Abstract:
The present invention discloses an air pump for a bedsore-preventing mattress. The present invention is characterized by an uneven part, which is capable of significantly reducing noise and which is disposed within an upper and lower case in order to minimize vibrations from an electric vibrator and a pumping member, operating noise of a damper and bellows, and noise caused by airflow. A cap covers an exposed portion of the damper. Noise from air flowing to a noise reduction barrel is minimized before the air is supplied to the mattress. Accordingly, a pleasant environment can be provided, and a configuration for assembling the pumping member, cap, and noise reduction barrel is simplified, thereby improving the productivity and durability of the air pump.
