So set, being made to realize to the wet and bacteriological filtration of oxygen by the way that wet magnificent paper and filter membrane to be placed in shell
With.
Further setting：The inner face of the lid is provided with water conservancy diversion rib.
So set, making oxygen after entering from machine end interface after water conservancy diversion rib guiding by adding water conservancy diversion rib
Patient's end interface is entered by humidifying paper again after being dispersed on filter membrane, to optimize bacteriological filtration effect, is prevented in air flow collection
By influencing its using effect in the middle part of filter membrane.
In summary：When by the way that lid being screwed in shell, flange enter inside elastic clamping block and and fastened with hook, thus anti-
Only lid is unclamped with respect to reverse, achievees the effect that sealing fastening.Or when by the way that lid being screwed in shell, wedge block passes through bullet
Property fixture block inside after and abut with the side wall of Elastic buckle, to prevent lid from unclamping with respect to reverse, reach sealing fastening
Effect；The inner ring of spanner work head is set on the periphery wall of shell and lid, by protrusion and the clamping of groove from
And shell and lid are tightened using spanner, realize laborsaving operation.
