It can be connected out) with inlet opening 41 with mixing chamber (not shown), intake antrum, water chamber can be connected with apopore 43
Logical, mixing chamber is connected between intake antrum and water chamber, and conduction hole 42 is connected with mixing chamber, and conduction hole 42 is positioned adjacent to
At intake antrum, the cross-sectional area of intake antrum is gradually reduced along water flow flow direction.
When passing through inlet opening 41 to when intake antrum water flowing, negative pressuren zone can be formed at conduction hole 42, by salt water cavity 301
In the mixing chamber of interior regenerant salt bilge suction pipe connector 40, and then regeneration salt water is sucked in resin cavity 201.Salt water is regenerated to enter
In softener resin tank 20, regeneration salt water pass through ion exchange resin, allow resin carry out ion exchange, restore resin go removing calcium and magnesium from
The ability of son.
Specifically, when the exchange capacity decline of ion exchange resin, when the removal rate of the water hardness is substantially reduced out, stream is used
Quantity sensor prompt, carry out regeneration of ion-exchange resin, can according to the loading of ion exchange resin, the hardness of water inlet,
Whether calculation processing water control ion exchange resin is regenerated.
According to one embodiment of present invention, pipe fitting 40 is Venturi tube.Venturi tube is directlyed adopt, without individually adding
Work, production are conducive to improve production efficiency, also, venturi tube structure is simple, and stability is high, can faster, more steadily
Make to form negative pressure at conduction hole 42, so that regeneration salt water be sucked in resin cavity 201.
According to one embodiment of present invention, on-off valve 50 is solenoid valve.Solenoid valve is directlyed adopt, structure is simple, passes through
The on-off in water route, realizes function switch between solenoid valve control draining hole 42 and salt water cavity outlet 32.I.e. when softener resin tank 20
When carrying out sofening treatment to water, control solenoid valve is in closed state；When needing to the amberlite in softener resin tank 20
When rouge carries out resin reducing/regenerating, control solenoid valve is in the open state.
Certainly, on-off valve 50 or manual switch are operated with manual switches control draining hole 42 and salt water cavity outlet 32
Between water route on-off, cost can be reduced, convenient for promote.When softener resin tank 20 carries out sofening treatment to water, close manually
Close on-off valve 50；When needing to carry out resin reducing/regenerating to the ion exchange resin in softener resin tank 20, open manually logical
Disconnected valve 50.
As shown in Fig. 2, according to another embodiment of the invention, control valve group includes: the first control valve 51 and second
Control valve 52, one end of the first control valve 51 form inlet opening 41, and the other end of the second control valve 52 forms apopore 43.Second
