Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition The concrete meaning of language in the present invention.

A kind of big flow reverse osmosis water purifier as shown in Figure 2, including front filter element 1, reverse osmosis membrane filter element 2 and postposition Filter core 3 is connected between front filter element 1 and reverse osmosis membrane filter element 2, reverse osmosis membrane filter element 2 and postposition filter core 3 by main line 40 It is logical.Wherein, front filter element 1 may include the multi-stage filters such as PP cotton filter element, seed activity filter core, carbon-point active carbon filter core；Postposition Filter core 3 can be using such as active carbon filter core.

Water purifier further includes the pure water tank 5 for being connected to 2 downstream of reverse osmosis membrane filter element, and pure water tank 5 is by bye-pass 41 and instead Main line 40 between infiltration membrane filter 2 and postposition filter core 3 is connected.Flexible leather bag is set in pure water tank 5, and pure water is stored in Between flexible leather bag and pure water tank 5, in the present embodiment: flexible leather bag is specially rubbery human body 50.Its principle are as follows: rubbery human body Filled with gas in 50, when the water for having pressure enters in pure water tank 5, the gas of rubbery human body 50 is compressed, and gas is compressed Volume becomes smaller afterwards, and pressure value increases, and when the pressure of gas pressure and water reaches consistent, stops water inlet；When the pressure drop of water When being greater than hydraulic pressure down to gas pressure, the gas expansion of rubbery human body 50 water between pure water tank 5 is discharged, until gas When pressure and the pressure of water arrive again at consistent, stop draining.

Water purifier further includes for controlling control assembly whether water filling into pure water tank 5.In the present embodiment: control unit Part includes for monitoring the pressure monitoring component 60 of pressure in pure water tank 5, the water pump 61 for filling the water to pure water tank 5 and control Component 62, pressure monitoring component 60 are connected with control unit 62, and control unit 62 is connected with pressure monitoring component 60.Its In: water pump 61 specifically can be set on the main line 40 of 2 upstream of reverse osmosis membrane filter element.Pressure monitoring component 60 can specifically be set Set 41 downstream of bye-pass, 3 upstream of postposition filter core main line 40 on, can be using such as pressure sensor.Pure water can be set Minimum setting value in tank 5 is 20psi, highest set value 60psi.

When not having water in pure water tank 5, the pressure in pure water tank 5 is lower low, and pressure monitoring component 60 monitors that pressure is low When minimum setting value 20psi, feedback signal controls water pump 61 and opens to control unit 62, control unit 62, carries out water processed, water It begins to flow between pure water tank 5 and rubbery human body 50；When the water in pure water tank 5 is more and more, pressure monitoring component 60 is monitored When pressure is more than highest set value 60psi, to control unit 62, control unit 62 controls water pump 61 to be stopped to pure water feedback signal It is filled the water in tank 5.When faucet is opened, water is squeezed out faucet by the inner compressed rubbery human body 50 of pure water tank 5, obtains pure water.

The application allows the pure water of generation to be stored in pure water tank 5 by increasing pure water tank 5, even if subsequent have metal ion It is permeated and is also diluted, there is rubbery human body 50 in pure water tank 5, rubbery human body 50 can be the pure water in pure water tank 5 when water intaking It presses out, the water TDS that user obtains would not be high.

The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention. All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it It is interior.
