Description

Water-saving reverse osmosis water purifier
Technical field
The present invention relates to water purifier field, more particularly to a kind of water-saving reverse osmosis water purifier.
Background technology
Reverse osmosis water purifier often produces 1 liter of filter water in the prior art, it is necessary to 3 liters or so of waste water is discharged, and in reality Sometimes due to the factor such as water pressure, water temperature, the discharge capacity of condensed water is bigger, significantly waste water resource in use.
Also occurs the water-saving technology of some anti-penetration water purifiers in the market:Reduce concentrated water than flow, increase simultaneously Add-back stream, before part concentrate recirculation to RO films, filtered again, reduce concentrated water discharge while also extend the use of RO films Life-span;Reduce concentrated water than flow, no backflow, employ the backwashing manner of pulse to extend the life-span of RO films.Both modes During pure water processed, there is concentrated water discharge, for the actual recovered rate of water less than 50%, the third water saving mode is by the row of RO films The concentrated water bled off is got up with container collection to be utilized again, but the TDS values of concentrated water that this mode container gives off are not high, typically It is that pure water respectively accounts for 50% or so with concentrated water, therefore collection concentrated water container volume is bigger, while product has two water tanks difference For storing concentrated water and pure water, installation trouble and occupy that space is big, the besides bad control of the use ratio of pure water and concentrated water, if The pure water use of collection is more, and concentrated water uses less, and concentrated water storage is full in water tank, and subsequently caused concentrated water can not just collect, must It must discharge, cause the waste of water resource.
The content of the invention
The shortcomings that present invention produces a large amount of waste water when being run for anti-penetration water purifier in the prior art, there is provided one kind production Water rate is high, the water-saving reverse osmosis water purifier of long, the compact-sized simple installation of filter core service life.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
Water-saving reverse osmosis water purifier, including water purifier water inlet pipe, booster pump and reverse osmosis membrane filter element, reverse osmosis membrane filter element Provided with reverse osmosis membrane filter element water inlet pipe, waste water outlet pipe and pure water outlet pipe, booster pump by reverse osmosis membrane filter element water inlet pipe with Reverse osmosis membrane filter element is connected, in addition to water tank, water tank are provided with water tank water inlet pipe and water tank outlet pipe, water purifier water inlet Pipe is connected on water tank water inlet pipe, and water tank is connected by water tank outlet pipe with booster pump, useless on reverse osmosis membrane filter element Water outlet pipe is connected with waste water ratio, and waste water ratio is connected with water tank water inlet pipe.
Preferably, the first non-return valve for also including the 3rd magnetic valve, being connected with water tank water inlet pipe, the first non-return valve string The first magnetic valve is associated with, the first magnetic valve is connected with the waste water outlet pipe on reverse osmosis membrane filter element, and the 3rd magnetic valve is connected to useless On water outlet pipe.3rd magnetic valve is used to discharge the water in water tank.
Preferably, water tank outlet pipe is provided with TDS testers.TDS refers to the concentration of total dissolved matter in water, main What is reflected is the concentration of underwater gold category ion, and TDS testers are used to detect TDS values.
Preferably, pressure-reducing valve, PP cotton filter cores, the first active carbon filter core, the 4th are sequentially connected in series on water purifier water inlet pipe Magnetic valve, the 3rd non-return valve.PP cotton filter cores, the first active carbon filter core can remove bulky grain in water inlet as prime filter Impurity.
Lived preferably, being sequentially connected in series second solenoid valve, the second non-return valve, high-voltage switch gear and second on pure water outlet pipe Property filtration core.High-voltage switch gear is a kind of pressure switch, and when the water of pressurized tank is full, the back-pressure effect of pressurized tank jumps high-voltage switch gear Rise, so as to play a part of cut-out supercharging pumping source.
Preferably, also including pressurized tank, pressurized tank is connected on pure water outlet pipe, the company of pressurized tank and pure water outlet pipe Contact is between high-voltage switch gear and the second active carbon filter core.
Preferably, water tank air bag and pressurized tank air bag are respectively equipped with water tank and pressurized tank.Water tank and pressure Tank is a tank body for being used for water storage and the air bag of a tank interior.Air bag in tank body can increase water tank and pressure Pressure in tank, beneficial to the water outlet of water tank and pressurized tank.
Preferably, also include double depotition cocks and the first tap water inlet pipe, the second water that are connected with double depotition cocks Leading water inlet pipe, the first tap water inlet pipe are provided with flow switch, and the first tap water inlet pipe is connected with waste water outlet pipe, the Two tap water inlet pipes are connected with the second active carbon filter core.Flow switch is used for detecting by the water of the first tap water inlet pipe Flow.
The present invention is as a result of above technical scheme, by storage of waste water caused by anti-penetration water purifier, it is necessary to use When release waste water, user can independently select to make quality of water according to the different purposes of water, while when waste water in water tank When excessive concentration may damage reverse osmosis membrane filter element, the present invention plays guarantor to reverse osmosis membrane filter element by water in emptying water tank Shield acts on.
