Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, the water purifier of the present embodiment comprises for removing the cascade filtration unit 1 of water impurity, cascade filtration unit 1 comprise the cotton filter core of the use PP being connected in pipeline remove the first step filtering unit 11 of impurity in water, with active carbon filter core remove impurity in water second stage filtering unit 12, with reverse osmosis membrane filter element, remove the third stage filtering unit 13 of impurity in water and with composite filter element, remove the fourth stage filtering unit 14 of impurity in water.In pipeline, be also in series with for the stabilized pressure pump 2 of the stable water of output pressure with for calculating the under meter 3 of the workload of water purifier.
The water purifier of the present embodiment calculates the workload of water purifiers by under meter 3 so that in good time replacing filtering unit 1, be equipped with filtration medium for removing the filter core of water impurity.Avoided the problem that causes filter effect to reduce because of the excessive use of filter core.The waste of also avoiding spendable filter core to be still replaced simultaneously and bringing.
Preferably, under meter 3 is arranged at the downstream of stabilized pressure pump 2.In the present embodiment, under meter 3 comprises turbine blade and the permanent magnet steel that is subject to water impact and rotates, and when magnetic line of force that turbine blade cutting is produced by permanent magnet steel, will produce the pulse signal being directly proportional to flow velocity.Then, under meter 3 umber of pulses are transformed into the flow of water.Therefore, the variation of hydraulic pressure has a strong impact on stability and the Measuring Precision of under meter 3.The water purifier of the present embodiment is arranged under meter 3 in the downstream of stabilized pressure pump 2.Due to stable water pressure herein, therefore improved the tolerance range of the metering of under meter 3.
More preferably, the water outlet of stabilized pressure pump 2 is directly communicated with the water-in of under meter 3.Stabilized pressure pump 2 is directly communicated with under meter 3.Between stabilized pressure pump 2 and under meter 3, do not arrange as any parts such as filtering units, avoided being arranged at the problem of the component affects stable water pressures such as filtering unit between stabilized pressure pump 2 and under meter 3, further, improved the tolerance range of under meter 3.
In the present embodiment, water purifier comprises the first step filtering unit 11 that uses the cotton filter core of PP to remove impurity in water, and stabilized pressure pump 2 and under meter 3 are successively set on the downstream of first step filtering unit 11.Because the cotton filter core of PP has certain water storage function, therefore, when the hydraulic pressure of the water-in of water purifier is unstable, the cotton filter core of PP can play certain shock absorption to guarantee the stable current of stabilized pressure pump 2 output pressures.Further, improved the tolerance range of the under meter 3 of water purifier.
Water purifier also comprise with active carbon filter core remove impurity in water second stage filtering unit 12, with reverse osmosis membrane filter element, remove the third stage filtering unit 13 of impurity in water and with composite filter element, remove the fourth stage filtering unit 14 of impurity in water, under meter 3 is arranged on the upstream of second stage filtering unit 12, third stage filtering unit 13 and fourth stage filtering unit 14.This has effectively been avoided the disadvantageous effect that second stage filtering unit 12, third stage filtering unit 13 and fourth stage filtering unit 14 cause the stability of hydraulic pressure and has affected the problem of tolerance range of the under meter 3 of water purifier.
In the present embodiment, water purifier also comprises magnetic valve 5, and magnetic valve 5 is arranged on the upstream of stabilized pressure pump 2.Water purifier also comprises that the first pressure switch 6, the first pressure switches 6 are arranged at the downstream of cascade filtration unit 1.
The pressure of the water detecting when the first pressure switch 6 is less than after set(ting)value, and the first pressure switch 6 is controlled magnetic valves 5 and cut off current, with prevent filtering unit 1 break down after water purifier work on and cause filter effect to reduce.
Water purifier also comprises that the second pressure switch 7, the second pressure switches 7 are arranged at the upstream of stabilized pressure pump 2.In the present embodiment, the second pressure switch 7 is providing between the water source and first step filtering unit 11 of water to be clean.Magnetic valve 5 is arranged between first step filtering unit 11 and stabilized pressure pump 2.
When the water-in hydraulic pressure of water purifier cannot guarantee the stable current of stabilized pressure pump 2 output pressures, the second pressure switch 7 is controlled magnetic valves 5 and is cut off current, to avoid stabilized pressure pump 2 output pressures to affect the problem of tolerance range of the under meter 3 of water purifier compared with little current.
Water purifier also comprises reverse checkvalve 4, and reverse checkvalve 4 is arranged at the downstream of cascade filtration unit 1.Preferably also be positioned at the upstream of the first pressure switch 6.Reverse checkvalve 4 affects the problem of the working efficiency of filtering unit 1 for preventing filtered water backflow.Solved the reflux problem of the Measuring Precision affect under meter 3 of the water that is arranged in a plurality of filtering units 1.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
