Liquid storage chamber 210 on.In this way, outtake tube 210 and air induction conduit 230 can be removed or be assembled together, share same sealing element
160, common identical connected structure, therefore reduce the quantity of components.
The inner space of liquid storage chamber 120 is usually limited, for the air guide tube assembly 200 including air induction conduit 230, out
The inclined direction of airway 210 and air induction conduit 230 can be on the contrary, such as Fig. 4-5 and Fig. 7.From side (the generally edge of liquid storage chamber
The extending direction of guiding tube 220) viewing, outtake tube 210 and air induction conduit 230 are cross-shaped.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 can be located at and draw
The lower section of conduit 220.In this way, the space utilization rate in liquid storage chamber can be made to optimize.Certainly, if the inside of liquid storage chamber 120
Space is enough, and the air inlet port 212 of outtake tube 210 can be lower than or wait the air outlet 234 higher than outtake tube 210.Out
The air outlet 214 of airway 210 and the air inlet port 232 of air induction conduit 230 can have of substantially equal height, certainly,
If necessary, they also can have not equal height.
In addition, the inner peripheral of sealing ring 160 is extend into liquid storage chamber 120 as shown in Fig. 6 and Fig. 8-9.Guiding tube 220
Gas backstreaming port 224 and 226 is respectively positioned on the surface for the part of sealing ring 160 extending into liquid storage chamber 210.Namely
It says, after the gas backstreaming port 224 and 226 of guiding tube 220 projects vertically downwards, falls in extending into for sealing ring 160
On part in liquid storage chamber 210.For the liquid storage chamber 120 of the even width up and down of diagram, it is believed that the inside of sealing ring 160
