Detailed Description
The exhaust silencer of the oxygenerator comprises an inner core 1, an outer sleeve 2, a filter element 3 and a silencing seat 4, wherein the left side of the inner core 1 is provided with an air inlet 5, the top end of the right part is closed, four exhaust holes 6 are uniformly formed in one circle of the side face, a baffle 7 is arranged on the left side of each air outlet 6, the edge of the baffle 7 is in closed connection with the left side of the outer sleeve 2, first silencing cotton 8 is stuck on the axial inner wall of the outer sleeve 2, a through hole 9 is formed in the center of the right side, the filter element 3 is in butt joint with the inner thread of the through hole 9, the silencing seat 4 is installed on the outer side of the filter element 3, the left side of the silencing seat 4 is opened, the outer sleeve 2 is in closed sleeve joint, a plurality of exhaust holes 10 are formed in the right end face, and second silencing cotton 11 is stuck on the axial inner wall of the silencing seat 4 and the inner wall of the exhaust holes 10.
Wherein the baffle 7 is integral with the core 1.
Further, the inner core 1, the outer sleeve 2and the silencing seat 4 are made of PP6 plastic or aluminum alloy, the filter element 3 is made of PE sintered filter elements, and the first silencing cotton 8 and the second silencing cotton 11 are made of non-woven fabrics.
The working mode of the invention is as shown in fig. 4 of the attached drawings: the gas is introduced into the air inlet 5 from the left side of the inner core 1, then enters the outer sleeve 2 through the air outlet 6, enters the filter element 3 through the buffer of the first mute cotton 8, is absorbed by the sound of the second mute cotton 11 on the inner wall of the silencing seat 4 through the buffer of the gas filtered out of the filter element 3, and finally is discharged through the air outlet 10.
The foregoing description is only illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, but rather the equivalent variations and modifications in shape, construction, characteristics and spirit according to the scope of the claims should be construed to be included in the scope of the claims.
