Direction flowing, it is to avoid enter the sidewall of gas direct collision liquid storage cylinder 120 and produce noise.Additionally, due to air induction conduit 230
Air outlet 234 relatively low, even if liquid accidentally enters air induction conduit 230 from air outlet 234, also can be back to liquid storage cylinder
In 120, it is to avoid enter main frame.Due to the existence of air induction conduit 230, extend the path that gas flows in liquid storage cylinder 120, because of
Steam after this can make gas and evaporate is sufficiently mixed, and then makes effluent air have desired humidity and temperature.
It is further preferred that the air outlet 234 of air induction conduit 230 Open Side Down.The air outlet of air induction conduit 230
The opening of 234 region be directly facing liquid level, the sidewall collision with liquid chambers 120 can be avoided to produce noise, and gas enters liquid
Behind chamber, the stop by liquid level can substantially uniformly be flowed towards surrounding, so beneficially gas with evaporate after steam abundant
Mixing.Air outlet 234 is preferably higher than the highest of liquid storage cylinder 120 can filling level.In this way, on the one hand liquid can be avoided
Body enters air induction conduit 230 from air outlet 234, and gas on the other hand can be avoided to enter what the bubble produced in liquid caused
Noise.
Preferably, airway assembly 200 also includes connector 240.Connector 240 is by the air outlet of outtake tube 210
It is fixed together with the air inlet port of air induction conduit 230.Connector 240 is additionally operable to airway assembly 200 is connected to humidifier
Liquid storage cylinder 210 on.So, outtake tube 210 and air induction conduit 230 can together with pull down or assemble, share same sealing member
160, the most identical connected structure, therefore decreases the quantity of parts.
The inner space of liquid storage cylinder 120 is typically limited, for including the airway assembly 200 of air induction conduit 230, goes out
Airway 210 can be contrary with the incline direction of air induction conduit 230, such as Fig. 4-5 and Fig. 7.From (the generally edge, side of liquid storage cylinder
The bearing of trend of guiding tube 220) viewing, outtake tube 210 is cross-shaped with air induction conduit 230.The air inlet of outtake tube 210
Port 212 is higher than the air outlet 234 of air induction conduit 230.Preferably, the air outlet 234 of air induction conduit 230 may be located at and draws
The lower section of conduit 220.As such, it is possible to the space availability ratio optimization in making liquid storage cylinder.Certainly, if the inside of liquid storage cylinder 120
Space is enough, the air inlet port 212 of outtake tube 210 can less than or wait and be higher than the air outlet 234 of outtake tube 210.Go out
The air outlet 214 of airway 210 and the air inlet port 232 of air induction conduit 230 can have an of substantially equal height, certainly,
If necessary, they can also have the height not waited.
Additionally, as shown in Fig. 6 and Fig. 8-9, the inner peripheral of sealing ring 160 extend in liquid storage cylinder 120.Guiding tube 220
Gas backstreaming port 224 and 226 is respectively positioned on the surface of the part extending in liquid storage cylinder 210 of sealing ring 160.Namely
Saying, after the gas backstreaming port 224 and 226 of guiding tube 220 projects vertically downwards, fall extending at sealing ring 160
In part in liquid storage cylinder 210.Liquid storage cylinder 120 for the even width up and down of diagram, it is believed that the inner side of sealing ring 160
Edge is more than the gas backstreaming port 224 and 226 distance to the sidewall of liquid storage cylinder to the distance of the sidewall of liquid storage cylinder 120.More
Saying, in the embodiment that guiding tube 220 is straight catheter of diagram, the spacing between gas backstreaming port 224 and 226 is fixed body
When justice is defined as B for the spacing between the part extending in liquid storage cylinder 210 of A and sealing ring 160, A is more than B.But,
It is appreciated that gas backstreaming port 224 and 226 does not the most press close to the sidewall of liquid storage cylinder 120, in order to avoid affecting gas flowing.But
For a fairly large number of situation of gas backstreaming port, even if pressing close to sidewall, to be likely to the impact on air-flow less, therefore ability
The technical staff in territory needs reasonably to select the quantity of gas backstreaming port under the design that the present invention provides, they are to liquid storage cylinder
