Description
Technical field
The utility model belongs to water-treatment technology field, is specifically related to a kind of household water filter.
Background technology
Raising along with people's living standard and the requirement to safe drinking water, household water filter is more and more higher in the popularity rate of China.Anti-penetration water purifier is one of water purifier that market is commonly used.Anti-penetration water purifier utilizes the principle of membrane sepn, pressure is applied to former water, by the filtration of reverse osmosis membrane, various salinity and the mineral substance of the overwhelming majority that ultra-filtration membrane cannot be removed can be removed, the water outlet of reverse osmosis machine is a kind of safe direct-drinking water, particularly for highly-saline tap water area, anti-penetration water purifier gets consumer reception very much.
But following phenomenon can be there is in anti-penetration water purifier in actual motion: reverse osmosis machine, after machine runs stopping again, has former water, pure water and condensed water in the reverse-osmosis membrane element in reverse osmosis filter core.Due to osmosis, soluble solid (TDS) in condensed water can enter in pure water through reverse osmosis membrane, when causing reverse osmosis machine again to run, the pure water TDS content that the initial stage produces water is high, and the TDS value of producing water after needing to run for some time just can reach normal value.
Patent documentation 1 (Chinese publication CN201210583511.1) provides the operation method of a kind of reverse osmosis purified water system and reverse osmosis purified water system, after reverse osmosis purified water system stops producing pure water, reverse osmosis membrane is stopped to exert pressure pump, close the entering water electromagnetic valve of reverse osmosis membrane, open air inlet electromagnetic valve, waste water outlet pipe is made to be in unobstructed state, booster air pump, inflate in reverse-osmosis membrane element, the gas that the former water of membrane element inside and dense water are charged is replaced, two-way penetration when avoiding shutting down in reverse osmosis membrane, thus TDS is lower when making again to start shooting initial stage pure water when running.But this patent exists following problem: on the one hand, inside ro components, inflation needs the water inside putamina to drain, and wastes water; On the other hand, owing to being filled with gas in membrane element in the method, again need to need during reverse osmosis water outlet to wait for the regular hour, gas is allowed to discharge, reverse osmosis membrane system is water processed again, and this system relates to inflation and gas barrier, and water producing cost is high, technique is more complicated, is unfavorable for maintenance and the popularization of machine.
Utility model content
Given this, the utility model, for this problem, provides a kind of water purifier and can solve anti-penetration water purifier and stop initial stage when again running to produce the high problem of the TDS content of water.
For solving the problem, the utility model can be reached by following measures: a kind of water purifier, this water purifier comprises the cotton strainer of PP, and activated charcoal filter and reverse osmosis membrane filt, be provided with valve and deionization filter core between the pure water water outlet of reverse osmosis membrane filt and final outflow water end.
The pure water water outlet of described reverse osmosis membrane filt is divided into two-way, the first via is provided with deionization filter core, and the pipeline between pure water water outlet and deionization filter core water-in is provided with valve, and the water outlet of deionization filter core is connected with final outflow water end; Second tunnel is provided with valve, and the water side of valve is connected with final outflow water end.
Compared with prior art, the utility model has the following advantages:
Time anti-penetration water purifier stops again running, not only the TDS content of initial stage product water is low, improves and produces water water quality; This device water producing cost is low simultaneously, and technique is simple, easy to maintenance, is convenient to promote.

Fig. 1 is structural representation of the present utility model.Fig. 2 is another kind of structural representation of the present utility model.Wherein, 1 is the initial feed-water end of water purifier, and 2 is the cotton strainers of PP, and 3 and 4 is all activated charcoal filters, 5 is topping-up pumps, and 6 is reverse osmosis membrane filts, and 7 is valves, and 8 is valves, 9 is deionization filter cores, and 10 is pure water final outflow water ends, and 11 is concentrated water discharge ends, and 12 is pure water water outlets.
Embodiment
In order to introduce the utility model simply, eliminating the description to known device and structure in the de-scription, below in conjunction with embodiment, the utility model being described further.
A kind of water purifier, this water purifier comprises the cotton strainer 2 of PP, activated charcoal filter, reverse osmosis membrane filt 6, is provided with valve 7 and valve 8 and deionization filter core 9 between the pure water water outlet 12 of reverse osmosis membrane filt 6 and pure water final outflow water end 10; Wherein the pure water water outlet 12 of reverse osmosis membrane filt 6 is divided into two-way, the first via is provided with deionization filter core 9, pipeline between pure water water outlet 12 and deionization filter core water-in is provided with valve 8, and the water outlet of deionization filter core 9 is connected with pure water final outflow water end 10; Second road outlet pipeline is provided with valve 7, and the water side of valve 7 is connected with pure water final outflow water end 10.
Described valve 7,8 can be identical or different, is selected from ball valve or magnetic valve, in order to improve water purifier intelligence degree, is convenient to the control of valve, preferred magnetic valve.
What install in reverse osmosis membrane filt 6 is the reverse-osmosis membrane element that preferred film flux is more than or equal to 200GPD.Reverse osmosis membrane flux refers to the water purification output through reverse osmosis membrane in the unit time, and the unit of membrane flux is GPD, i.e. gallons per day.Adopt the reverse osmosis membrane of large flux, effectively improve the reverse osmosis produced water yield to a great extent, meet the demand of user to large discharge, reduce pressure pot or pure water tank, effectively reduce water purifier volume.
Radical and the mode of connection of described activated charcoal filter are not particularly limited, preferred 1-4 root, in order to improve the effluent quality of activated charcoal filter, and the activated charcoal filter in this device more preferably 2 and connect according to the mode of parallel connection.Except activated charcoal filter effluent quality well except, pressure-losses when connecting compared to activated charcoal filter, activated charcoal filter connects according to the mode of parallel connection, and the pressure-losses can effectively reduce.The reduction of the activated charcoal filter pressure-losses, can increase the pressure of reverse osmosis filter feed-water end further, ensures the water production rate that reverse osmosis filter is larger.
