Abstract
Provided is an exhaust silencing device of an oxygenerator. A silencing cylinder of a closed cylindrical structure is used, a plurality of straight-plate-type blocking plates are arranged in the silencing cylinder, the blocking plates are different in length and are horizontally distributed in the silencing cylinder, two exhaust pipes are arranged and are connected at the two ends of the silencing cylinder respectively, wherein one exhaust pipe is connected with a switching valve, and the other exhaust pipe is connected with an output device. The silencing cylinder is arranged in an exhaust device, so that gas has a buffering effect during exhausting, exhaust pressure is lowered when gas is exhausted, and accordingly noise is lowered, and the design of the silencing cylinder accords with the silencing principle of the PVC silencing cylinder. The output device is connected at the tail end of the exhaust pipe placed at one end of the silencing cylinder, a plurality of small gas outlets are formed in the upper circle face of the output device so that gas on the upper circle face of an exhaust funnel can be dispersed and output after nitrogen passes through the silencing cylinder, and therefore the device is better in silencing effect during oxygenerator exhausting.
