The pure water water flow of 1 pure water water outlet of reverse osmosis membrane filter element is monitored by being discharged integrated flow to water inlet and pure water, can
The service life of reverse osmosis membrane filter element is judged and predicted to realize.Preferably, the elements such as the above TDS sensor, flowmeter are logical
It crosses the communication modules such as WIFI, bluetooth, GPRS to connect with mobile terminal communication, be carried out for the detection data to water purification machine real-time
Report.Therefore filter element life and each component life can not accurately be calculated, can not obtain water purification machine failure cause institute by solving water purification machine
The big problem of caused water purification machine maintenance difficulty.
For another example, the structure based on above-mentioned water purification machine can also be achieved the control that maintenance is shut down to water purification machine.Pure water outlet pipeline
First pressure sensor 17 is provided on 200, which is used to detect the hydraulic pressure of pure water outlet pipeline 200, when reaching
Control water purification machine stops water processed when default hydraulic pressure value, and carries out shutdown maintenance.Second pressure sensor 19 is reverse osmosis for detecting
Hydraulic pressure before film assists reverse osmosis membrane cleaning and protection control.By the 3rd TDS sensor to the TDS value of reverse osmosis membrane waste water side
It is measured in real time, can effectively control the time for terminating pure water reflux when maintenance when pure water reflux shut down, rather than it is sharp
It is rinsed with the pure water reflux of firm discharge or fixed duration is rinsed in reflux.
As the preferred embodiment of the embodiment of the present application, water purification machine may also include from suction nozzle, and inlet pipeline passes through self-priming
Head is connected to external water source, is used to carry out primary filtration to raw water from suction nozzle, those skilled in the art can voluntarily select as needed
Select setting.
As the preferred embodiment of the embodiment of the present application, water purification machine may also include water butt, and water butt is arranged in pure water
Outlet pipeline 200 and pure water return line 300 are connected before end, and purified pure water is temporarily stored in bucket, compression is passed through
Air in air bag forms pressure, and when pure water outlet pipeline 200 is drained, air bag is just released stress, by the pure water in bucket
Discharge, to play the role of water storage and draining.Those skilled in the art can reasonably select setting water butt as needed.
Specifically, opening second solenoid valve 6 when pure water machine system enters shutdown status, utilizing post active carbon filter core
A small amount of remaining pure water in 11 or the pure water in above-mentioned water butt are back to booster water pump 2 and subsequent pipeline, it is optimal make it is subsequent
TDS value reaches pure water TDS value in pipeline, to realize the protection of each component of water purification machine.
