The composition material specific gravity of valve member 4, which is higher than water, can avoid to compare because of the hydrostatic pressing that liquid generates in humidifying liquid container 8 Liquid outlet 61 is pressed to lower than the valve member 4 of water again and closes liquid outlet 61, so that liquid 0 cannot be introduced into liquid containing sky Between 102.

Further, when because oxygen delivery pipeline 9 reasons such as closes by folder cause 10 pressure of container intracavity excessive when, valve portion The buoyancy member 3 that part 4 is connected by the connecting component 40 of hard, is pressed towards 601 direction of entrance of valve member accommodating chamber 600, from And closed, humidification fluid 0 will not continue reflux rewetting liquid container 8.

The liquid transmission pipeline 65 can via in container intracavity 10, container intracavity 10 is outer and any side in attached wall path Valve member accommodating chamber 600 is connected by formula with liquid inlet 62, can also be direct by valve member accommodating chamber 600 and humidifying liquid container 8 It is connected.

" the attached wall path " refers to that liquid transmission pipeline 65 at least one, the inside and outside wall of container 1 is attaching state, maximum Degree saves space and shape is more aesthetically pleasing, the inside and outside wall of container including independent liquid transmission pipeline 65 insertion recess, can also To be a component and the inside and outside wall of container is tightly connected and forms liquid transmission pipeline.

65 one end of liquid transmission pipeline of the present embodiment is connected with the liquid inlet 62 on container 1, the other end and valve member The entrance 601 of accommodating chamber 600 is connected.

In humidifying liquid container 8 liquid be introduced into the liquid incoming port 62 of 1 gas outlet of humidification device container, 121 adjacent place again by Liquid transmission pipeline 65 is delivered to valve member accommodating chamber 600, injects the liquid-retaining volume 102 of container intracavity 10, until buoyancy Component 3, which floats, drives valve member 4 to close the liquid outlet 61 of valve member accommodating chamber 600.

Further, 3 main body of buoyancy member can annular in shape, the centrifugal distribution of colyliform.

Cyclic annular, colyliform the complete or partial hollow out of 3 central part of buoyancy member, can make dry oxygen contact more liquid Face 00, to realize better humidifying effect；It is described it is centrifugal distribution refer to buoyancy member expose liquid level 00 partially away from appearance Device center avoids the interference to oxygen flowing.

Further, it in the oxygen approach 110 of humidification device container 1 or can be connected at second entrance 112 and be flowed with gas And liquid surface fluctuation component 115 that is mobile and neighbouring or probeing into liquid level 00, liquid surface fluctuation component 115 can be strip of sheet flexible (figure omits).

" liquid surface fluctuation " is to occur that liquid level 00 to the greatest extent by the direct effect of gas turbulence or liquid surface fluctuation component 115 It irregular may continuously fluctuate to promote the evaporation of liquid water, promotion humidifying effect, this example illustrates disturbance component 115 be blade structure.

A kind of extension of thinking is (figure omits), the pipe for the flexible thin-walled that oxygen approach 110 at least can be locally latched by inner cavity Road is constituted, and pipeline inner cavity is partly or wholly latched when " at least part locking " refers to no pressure difference or smaller pressure difference, and has pressure Inner cavity can then be impacted and be expanded when the gas of power enters；Locking, which can be, completely closed to be also possible to not exclusively be latched；Air-flow is logical Cross can make its thin-walled flexible occur non-uniform expansion and closure with expand different positions alternately, and make pipeline The position of opening constantly changes, and the gas turbulence of generation continues irregular disturbance liquid level to promote humidifying effect.
