Apply the circuit block diagram of the reverse osmosis water purifier of example.Referring to fig. 1 and fig. 2, in some embodiments of the utility model, reverse osmosis
Saturating water purifier 100 may include main waterway 110, pressure sensor 120, controller 130.Main waterway 110 includes mainly along water flow side
To water inlet 111, booster pump 114, reverse osmosis purified water unit 115 and the water outlet 119 set gradually.Reverse osmosis purified water unit
There is reverse osmosis membrane (RO film) in 115.Water inlet 111 can be connect with water sources such as water taps, to obtain source to be filtered
Water.Booster pump 114 can be pressurized the source water from water inlet 111, and pressurized source water is delivered to reverse osmosis net
Before the RO film of water unit 115.Source water into reverse osmosis purified water unit 115 has certain pressure because of pressurization, so reverse osmosis
Water purification unit 115 can accelerate water speed processed using the pressure, convert water purification for a part of source water.Reverse osmosis purified water unit
Water purification made from 115 can be exported through water outlet 119, such as clear water faucet.
The input side of booster pump 114 is arranged in pressure sensor 120, the pressure before being able to detect main waterway pump, especially
The pressure of non-intensified 114 pressurization of pump.Pressure sensor 120 is connect with controller 130, to be electric signal shape by pressure conversion
After the pressure signal of formula, which is transmitted to controller 130.Controller 130 is connect with booster pump 114, according to pressure
Pressure value controls the working condition of booster pump 4 before the pump of main waterway indicated by signal.It is worth noting that, removing pressure

Controller 130 can have first comparator 131.Before the pump of first end (anode in figure) the input main waterway of first comparator 131
The second end (negative terminal in figure) of pressure value P, first comparator 131 inputs first threshold Th1.The pressure value P before the pump of main waterway
When less than first threshold Th1, first comparator 131 exports first control signal (such as low level signal), this signal can allow
Booster pump 114 is out of service or runs lower than predetermined power.Pressure value P is greater than or equal to first threshold before the pump of main waterway
When Th1, the output control second control signal of first comparator 131, this signal can allow booster pump 114 to operate normally.It can be with
Understand, first control signal and second control signal (such as high level signal) can export after overdrive circuit again to booster pump
114.Here, predetermined power is significantly lower than the power that normally water processed is pressurized of booster pump 4, for example, 10%-20% of normal power.
Such setting can reduce reverse osmosis water purifier sending and make an uproar in the case where reverse osmosis water purifier does not have water purification or water inlet is few
The probability of sound.In some embodiments, first threshold Th1 can be set to 0.08Mpa.That is it is pressed before the pump of main waterway
When force value P is greater than 0 and is less than 0.08Mpa, booster pump 114 is out of service or low power run, and pressure value P is big before the pump of main waterway
When 0.08Mpa, booster pump 114 is operated normally.Also, the pressure sensor in the present embodiment is arranged in booster pump
Before, detection be main waterway water inlet pressure value.The present embodiment after booster pump and detects pressurized hydraulic pressure compared to setting
Mode it is more sensitive, control it is more accurate.
With continued reference to shown in Fig. 3, optionally, controller 130 can also have the second comparator 132, the second comparator 132
Pressure value P before the pump of first end input main waterway, the second end of the second comparator 132 input second threshold Th2, the second comparator
The output end of 132 enable end connection first comparator 131.When first comparator 131 exports second control signal (such as high level
Signal) when can enable the second comparator 132 and make its work.When second comparator 132 works, the pressure value before the pump of main waterway
When P is less than second threshold Th2, the second comparator 132 exports third and controls signal, which controls booster pump 114 with the first function
Rate operation；When pressure value P is greater than or equal to second threshold Th before the pump of main waterway, the 4th control of the second comparator 132 output
Signal, the signal control booster pump 114 with the second Power operation.It is appreciated that third control signal and the 4th control signal can
Exported again after overdrive circuit to booster pump 114.Here, the first power is greater than the second power.That is, working as main waterway
Pump before pressure value P it is smaller when, the running power of booster pump 114 is higher, to provide higher pressurization, meets reverse osmosis units
115 pressure demand；On the contrary, the running power of booster pump 114 is lower when pressure value P is larger before the pump of main waterway, thus only
The pressure demand that lower pressurization can meet reverse osmosis units 115 need to be provided.By this setting, this implementation it is reverse osmosis net
In water dispenser, controller 130 can be controlled booster pump 114 according to the pressure in main waterway 10, so that booster pump 114 is always
Work avoided high noisy caused by high-power output under suitable power.In some embodiments, second threshold Th2 can
To be set as 0.1Mpa.That is, when pressure value P is greater than or equal to 0.08Mpa and is less than 0.1Mpa before the pump of main waterway,
Booster pump 114 is with the first Power operation, and when pressure value P is greater than or equal to 0.1Mpa before the pump of main waterway, booster pump 114 is with the
Two Power operations.
In some embodiments, third threshold value Th3 can be set, pressure value P is greater than or equal to the before the pump of main waterway
When three threshold values, show that hydraulic pressure is enough, booster pump 114 can also be out of service or be run lower than predetermined power.In some embodiments
In, third threshold value Th3 can be set to 0.9Mpa.That is, pressure value P is greater than or equal to 0.9Mpa before the pump of main waterway
When, booster pump 114 is out of service or low power run.
In some embodiments, the first power and the second power can float within the scope of one, such as the first power is big
In 50W and it is less than or equal to 100W, the corresponding operating voltage of this power is greater than 24V and is less than or equal to 90V.Second power is big
In or equal to 15W and it is less than or equal to 50W, the corresponding operating voltage of this power is greater than or equal to 1V and is less than 24V.Some
In embodiment, the first power can be positively correlated with pressure value P before the pump of main waterway and the absolute value of the difference of second threshold Th2.Class
As, pressure value P and the absolute value of the difference of second threshold Th2 are positively correlated before the pump of the second power and main waterway.It can control
In device 130 before pump of the configuration error amplifier to detect main waterway pressure value P and second threshold Th2 difference, and it is poor according to this
It is worth and determines the first power and the second power.
With reference to Fig. 1 and Fig. 2, in some embodiments, reverse osmosis water purifier 100 also has inlet water solenoid valve 113.Water inlet electricity
The input side of booster pump 114 in main waterway 110 is arranged in magnet valve 113, more specifically between water inlet 111 and booster pump 114
