Description

A kind of central water purifier

Technical field

It the utility model is related to water purifier, especially household water filter.

Background technology

Water purifier is also water purifier, filter, is to carry out the small of deep purifying processing to water quality by the requirement to water Type water treatment facilities.The water purifier usually said, generally refer to be used as the minifilters that family uses.Water purifier is according to difference Cleaning principle and technique, many types can be divided.Wherein RO reverse osmosis technologies filtering accuracy highest, due to the hole of reverse osmosis membrane Footpath only has ten a ten thousandths of hairline diameter, only allows hydrone and dissolved oxygen by all impurity contained such as agricultures in water The harmful substance almost all such as medicine, bacterium, virus, heavy metal is trapped exclusion.Except reverse osmosis technology also has a lot of other mistakes Filter technology：Nanofiltration (filtering accuracy is between 0 .001-0 .0001 microns), (filtering accuracy is in 0 .1-0 .01 microns for milipore filter Between), refined filtration (filtering accuracy below 0 .1 microns, such as ceramic filter, PP cottons filter).PP cottons can effectively filter in water purifier Iron rust, sandstone, colloid and diameter in water removal are more than 5 microns all impurity, and grain active carbon filter core has superpower absorption Power, it can effectively adsorb the chemical agent such as chlorine residue in water, odor, heterochromatic, agricultural chemicals；Accurate activated carbon cartridge, can effectively it remove Bacterium, toxin, heavy metal in water etc..Application of the advanced water purifying technology in drinking water field so that the phenomenon of " not acclimatized " History can be quickly become, efficiently solve many places due in underground water harmful minerals it is exceeded and caused by region disease Disease.

Multistage filtering layer typically is used inside existing water purifier, if China Patent Publication No. is a kind of 205368017 family expenses Water purifier, including water valve, shell, bearing and central tube, active carbon layer, manganese layer of sand, far infrared are disposed with the shell Activation rock layers, magnet layer, medical stone layer, KDF layers and quartz sand layer, the upper water distributor are located in active carbon layer, the lower cloth Hydrophone is located in quartz sand layer.Although this kind of water purifier filter capacity is strong, synchronous deposits also easily causes the stifled of filter layer Plug, not only pollutes water mark, and have a strong impact on the water yield of water purifier.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of central water purifier, can realize in general water purifier Function, water yield is big, and can isolate the deposit in water purifier and quickly backwash and discharge.

The technical scheme of technical problem to be solved in the utility model is：A kind of central water purifier, including housing, setting Enclosure interior central tube and be arranged on the multiposition valve of case top；Form accommodating cavity in the housing, in housing under Portion is provided with filter plate, and accommodating cavity is separated into upper cavity and lower chamber by the filter plate, and the upper cavity is filter chamber, in upper cavity Provided with active carbon filtration layer, the lower chamber is solid pollutant settling chamber；The central tube is located at the centre bit of accommodating cavity Put, the upper end of central tube is connected with multiposition valve, and the lower end of central tube through the filter plate and is extended in lower chamber, central tube Bottom side of the wall opens up groove；The upper end of the central tube is cased with filter cap, the multiposition valve include body, water inlet end, water side, Backwash end and joystick.The utility model has water purification function and backwashing function, is switched over by multiposition valve；When opening When opening water purification function, running water enters central tube from water inlet end, in the lower chamber for flowing to housing along central tube, in the water of running water Under pressure effect, running water is entered in upper cavity by filter plate, and the pollutant of larger particles can be by filter plate stop and in lower chamber Deposition, after the active carbon filtration layer in upper cavity, chlorine and organic pollution for being filtered to remove in water etc., last filter water are led to Filter cap is crossed from water side water outlet；When opening backwashing function, running water enters from water inlet end, then from the upper of upper end Filter cap is exported to upper cavity, and the active carbon filtration layer that running water rushes to down through upper cavity enters lower chamber, the running water Conveying direction and water purification when on the contrary, active carbon filtration layer and the deposit being deposited in lower chamber quickly can be poured The lower end of central tube, the discharge of backwash end is connected to finally by central tube.

As an improvement, the housing is cylinder, the material of the housing and filter plate is PP.

As an improvement, the upper end of the housing is provided with opening, opening is provided with nipple, and the centre of nipple is provided with The through hole passed through for central tube, the nipple connect with housing for melting.

As an improvement, the nipple includes threaded portion and stopper, the diameter of the stopper is more than the diameter of opening, gear Portion and the lower end of opening offset.

As an improvement, the housing includes upper, middle and lower, passing through melting between the upper, middle and lower Connection.

As an improvement, the bottom of the housing is provided with base.

As an improvement, the lower end of central tube is provided with four grooves altogether, the width of groove is 4 ~ 6mm, the filter plate and shell Height between body bottom is 30 ~ 50mm.

As an improvement, active carbon material is filled up in the upper cavity forms the active carbon filtration layer.

As an improvement, doped with medical stone granule between active carbon material.

As an improvement, running water is formed by water inlet end, central tube, lower chamber, upper cavity, upper filter cap and water side successively Water filtering system；Running water forms recoil by water inlet end, upper filter cap, upper cavity, lower chamber, central tube and backwash end successively Wash system.

Caused beneficial effect is the utility model compared with prior art：

Including upper cavity and lower chamber in housing, lower chamber is as solid pollutant settling chamber, during unlatching backwashing function, It is when the conveying direction and water purification of running water on the contrary, can be quick by active carbon filtration layer and the deposit being deposited in lower chamber The lower end for pouring central tube, finally by central tube be connected to backwash end discharge.

Brief description of the drawings
