It is preferred that, the inlet channel is provided with magnetic valve, and the magnetic valve is controlled by the float being located on bung.
It is preferred that, the cleaning pipeline is provided with cleaning switch and hand switch, the hand switch control liquid storage boxOpening and closing.
It is preferred that, the agitating device includes agitator arm, sealing strip, time switch and drives what agitator arm was rotatedMotor.
It is preferred that, it is described to 1~2cm, the drainpipe is tilted down at drainpipe to there are two openings to set with liquid bottom of the barrelPut, an opening is by solenoid valve control, and magnetic valve is arranged right below time switch, and magnetic valve links with cleaning switch, anotherIndividual opening is by manual switch control.
It is preferred that, the bung with liquid bucket is made up of 2/3rds fixed lid and 1/3rd removable cover, describedRemovable cover is provided with opening handle.
It is preferred that, the fixation that the inlet channel, agitating device and float are each provided at bung is covered.
(3) beneficial effect
The invention provides a kind of liquid dispensing device for haemodialysis, the liquid mixing system of the device can realize dialyzateAutomatically configure, the fixed float covered can manual adjustment height, to control the magnetic valve of inlet channel, so as to realize onceConfigure the target of many parts of dialyzates；Sterilizing purging system can disappear to carrying out automatic cleaning with liquid bucket and inlet channel with semi-automaticPoison, it is to avoid the growth of bacterium, it is ensured that the cleaning of dialyzate.
