It can be understood by those skilled in the art that, in the conventional table-top water purification equipment, after being used for a period of time, the RO filter element 14 is backwashed by wastewater, because the raw water and the wastewater have more impurities, during the backwashing process, the wastewater flows back to the raw water chamber 111, the concentration of the raw water in the raw water chamber 111 is continuously increased, the risk of scaling and blocking of the RO filter element 14 and the wastewater valve 18 is high, and in the conventional treatment method in the market, a scale inhibitor is added into the raw water chamber 111 or the pre-positioned filter element 13 to inhibit scaling, but the scale inhibitor is generally a chemical reagent, organic substances are separated out during the treatment process, and environmental problems such as water eutrophication and the like are caused by the discharge of the wastewater.

To this end, the present application proposes a pure water backwashing method, and specifically, as shown in fig. 1 and 2, a pure water return flushing waterway 22 is connected to the pure water tank 15, and the pure water return flushing waterway 22 at least flushes the RO cartridge 14. That is, after the desktop water purifying equipment works for a period of time, the RO filter element 14 can be backwashed by using the pure water in the pure water tank 15, and because the pure water has less impurities, the dirt on the surface of the RO filter element 14 can be taken away, the filtering capacity of the RO filter element 14 is improved, and the service life of the desktop water purifying equipment is prolonged.

In an alternative embodiment, as shown in fig. 1, a pure water return flushing water circuit 22 is connected to the water inlet end of the RO cartridge 14, and the pure water return flushing water circuit 22 is provided with a third water pump 23 and a second check valve 24 in sequence, and the second check valve 24 allows the water in the fresh water tank 15 to return to the RO cartridge 14. When the pure water backflow backwashing process is started, the third water pump 23 and the waste water valve 18 are started, pure water in the pure water tank 15 is driven to flow back to the water inlet end of the RO filter element 14 through the third water pump 23, dirt on the surface of the RO filter element 14 is taken away by the pure water in the flowing process, one part of the pure water passing through the RO filter element 14 returns to the pure water tank 15 through the pure water waterway, and the other part of the pure water flows into the waste water chamber 112 in the water tank 11. Since the pure water return flushing waterway 22 is connected to the water inlet end of the RO cartridge 14, the pure water is driven to flow between the RO cartridge 14 and the clean water tank 15 only by the third water pump 23, and the water in the RO cartridge 14 is completely replaced by the pure water during the pure water circulation, thereby achieving the purpose of cleaning the RO cartridge 14.

The backwash procedure of the above embodiment may specifically be as follows, S201: starting the third water pump 23 and the waste water valve 18, and disconnecting the water path 152 and the water outlet path 151 of the fresh water; s202: at the end of the flushing, the third water pump 23 and the waste valve 18 are closed. In this process, the first water pump 16 and the second water pump 20 are both in a closed state, so that the pure water in the pure water tank 15 does not flow back to the raw water chamber 111 of the water tank 11 and is not sent out, and the stable water flow of the backwashing program is ensured. Wherein the back flushing time may be between 10 and 120 seconds. It is understood that the above-mentioned back flushing time may be higher than 120 seconds or lower than 10 seconds, and the flushing time may be extended or shortened according to the local water quality.

In an alternative embodiment, as shown in fig. 2, the pure water return flushing waterway 22 is connected to the water inlet end of the self-priming pump 12, the pure water return flushing waterway 22 is provided with a first electromagnetic valve 25, and a second electromagnetic valve 26 is arranged between the self-priming pump 12 and the raw water chamber 111 of the water tank 11. In this embodiment, first solenoid valve 25 is used for conducting pure water backward flow washing water route 22, and second solenoid valve 26 is used for conducting former hydroecium 111 and self-priming pump 12, and when starting back flush procedure, self-priming pump 12 and first solenoid valve 25 open, and the water in the water purification case 15 gets into RO filter core 14 under the suction of self-priming pump 12, washes RO filter core 14 to cut self-priming pump 12 and former hydroecium 111 through second solenoid valve 26.

Referring to fig. 4, the backwash procedure of the above embodiment may specifically be as follows: s301: the first solenoid valve 25 is opened, the second solenoid valve 26 is closed, and the fresh water path 152 and the outlet water path 151 are disconnected. S302: after the flushing is completed, the first solenoid valve 25 is closed, and the second solenoid valve 26 is opened to return to the standby state. In this embodiment, the water outlet of the pure water return flushing waterway 22 is connected to the inlet end of the self-priming pump 12, and the pure water in the pure water tank 15 is sucked by the self-priming pump 12, so that the RO filter element 14 is flushed by the pure water. Wherein, the pure water backflow flushing waterway 22 can be connected in front of the inlet end of the front filter element 13, so that the pure water can also clean the front filter element 13. Because in this embodiment, the purified water in the purified water tank 15 is pumped by the self-priming pump 12, the backwashing can be realized by controlling the on-off of the two electromagnetic valves without additionally arranging a water pump, and the manufacturing cost of the table type water purifying equipment can not be increased.

In this embodiment, the back-flow flushing time may be different depending on whether the waste valve 18 is opened, and in the case where the waste valve 18 is opened, the back-flow flushing time is 10 to 120 seconds, in which case, since a part of the water flow may flow away from the waste valve 18 and the flushing flow rate is fast, the flushing time may be set to be short, or in the case where the waste valve 18 is not opened, the back-flow flushing time may be 10 to 300 seconds, in which case, the flushing water flow may pass through the pre-filter element 13, the RO filter element 14, and the like in sequence, the flushing flow is long, and the back-flow flushing time may be long.

In addition, the first solenoid valve 25 and the waste water valve 18 can be opened intermittently to generate a rapid and instantaneous backflow flushing water flow, which is more favorable for taking away the dirt of the RO filter element 14.
