Embodiment

The technical scheme of this patent is described in more detail with reference to embodiment.

Referring to Fig. 1, a kind of waterway control system of direct drinking fountain, including counter-infiltration system 1 and water outlet water circuit system 9, The water outlet water circuit system 9 includes storage tank 3, suction pump 4, tap 7 and active carbon filter core 8, and ball float is provided with storage tank 3 2 and storage tank 3 be connected by pipeline with one end of suction pump 4, the other end of suction pump 4 passes through pipeline and active carbon filter core 8 one end is connected, and the other end of active carbon filter core 8 is connected with tap 7 and between tap 7 and active carbon filter core 8 Non-return valve 5 and pressure switch 6 are provided with, counter-infiltration system includes RO filters 10, CTO filters 11, UDF filters 12, PP Filter 15 and transfer tube 16, RO filters 10 are connected by pipeline with storage tank 3, RO filters 10 respectively with CTO filters 11 one end is connected with sewage draining exit 13, and the other end of CTO filters 11 is connected with one end of UDF filters 12, UDF filterings The other end of device 12 is connected with the side of transfer tube 16 and is provided with the first electromagnetism between UDF filters 12 and transfer tube 16 Valve 14, the opposite side of transfer tube 16 are connected with one end of PP filters 15, and the other end of PP filters 15 is connected with running water pipe It is logical.Microswitch is provided with ball float 2.Second solenoid valve 17 is provided between RO filters 10 and sewage draining exit 13.

Operation principle of the present utility model is：The course of work of the direct drinking fountain waterway control system, is comprised the following steps that：

Step 1, during water processed, running water passes through PP filters 15, UDF filters 12, CTO filters 11 and RO mistakes successively Filter 10 obtains pure water, and pure water flow to storage tank 3, until liquid level rises to the ball float 2 with microswitch and disconnected, counter-infiltration system 1 is stopped；

Step 2, open tap 7 and discharge water, the pressure in the pipeline of water outlet water circuit system 9 declines, and pressure switch 6 is closed, taken out Water pump 4 switches on power start-up operation, and the water source in storage tank 3 is evacuated into tap 7 through active carbon filter core 8 and discharged, realizes water outlet The process that discharges water of water circuit system 9；

Step 3, tap 7 is closed, suction pump 4 works on, until the pressure in non-return valve 5 to the pipeline of tap 7 reaches To the disconnected value of jump of pressure switch 6, now suction pump 4 is stopped.

Non-return valve 5 can prevent the pressure reversal in pipeline from flowing backwards, and play a part of keeping loine pressure, control suction pump 4 operation.The system does not use automatically controlled programme-control suction pump and discharging valve the combination realization water of traditional complexity, optimizes work Skill, the production process of equipment is reduced, improve production capacity, effectively reduce the manufacturing cost of product, the system eliminates outside water storage and supplied Pressure device, product installing space, and built-in storage tank 3 are reduced, pressure switch 6 is employed and non-return valve 5 combines, utilize opening Tap 7, which discharges water, pressure release and closes tap 7 pressure and rises and realize to start suction pump 4 and stop, at the same improve water flow and Discharge water flow velocity, increases the effluent flux of tap 7, meets the use demand of user.
