Compared with the prior art, the utility model discloses compact structure, volume are less, and the filtration purification effect is better, equipment convenient and fast, and the specially adapted is portable or remove the water purifier.

Description

A kind of compound filtering core of water purifier

Technical field

This utility model relates to water purification system technical field, especially a kind of water purifier composite filter element.

Background technology

At present, traditional water purifier filter element generally adopts following filtration order: PP cotton filter element, active carbon filter core, PP cotton filter element, RO membrane cartridge, post active carbon filter element, owing to tap water is carried out disinfection by the compound of chlorine in water factory's disinfecting process, therefore almost all of tap water all contains the composition of chlorine, at tap water by Combination filter element purification process, if the chlorine component in tap water can not get effective removing, can aoxidize, corrosion RO membrane cartridge below, affect the service life of RO film, RO film manufacturing cost is also above other filter elements, add the later maintenance cost of consumer, if RO membrane cartridge is changed not in time, the filter effect of water purifier can be affected again.

Reverse osmosis water purifier preconditioning technique is generally adopted level Four and filters; such as: first order PP cotton filter element layer; for removing silt in water and naked eyes visible; second level grain active carbon filter element layer; for removing the chlorine residue in water; third level PP cotton filter element layer, for removing fine particle further, the fourth stage adopts RO rete to filter. PP cotton material needed for level Four pre-flock technology is more, utilizes abundant not, it is easy to cause the waste of material. Common bulk granular carbon filter element layer, carbon ash is relatively big, and first use has the outflow of black current, and bulk granular carbon filter element granule its surface area big is little, and adsorption efficiency is low, and clean-up effect is weak. The water pretreatment of prior art needs multistage purification, and material cost is high, and structure is complicated, easily leaks, and purifies thorough not, and service life is short, and volume is bigger.

Utility model content

The purpose of this utility model is to provide a kind of compact conformation, small volume, the good compound filtering core of water purifier of filtration, purification effect.

The purpose of this utility model is achieved by the following technical solution:

Compound filtering core of water purifier, including shell, upper end cover, filter element main body and bottom end cover, filter element main body is located in airtight shell, upper end cover be respectively provided on two sides with water inlet and pure water inlet, bottom end cover is provided with blowoff valve, it is provided with drainage screen between water inlet and the filter element main body of described upper end cover, between filter element main body and described drainage screen, is provided with the deflector guiding water (flow) direction.

As optimal technical scheme of the present utility model, described drainage screen is stainless steel filter screen.

As optimal technical scheme of the present utility model, described filter element main body is made up of at least three layers filter material, and its ground floor filter material is PP cotton filter course, and second layer filter material is magnetization or infrared function material layer, and third layer is NF membrane, RO film or Hollow Fiber Ultrafiltration layer.

As optimal technical scheme of the present utility model, described filter element main body pottery or composite molecular screen filter course are arranged below.

The beneficial effects of the utility model are: relative to prior art, this utility model compact conformation, small volume, and filtration, purification effect is better, easy to assembly fast, be particularly well-suited to portable or mobile water purifier.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1, upper end cover, 2, filter element main body, 3, shell, 4, water inlet, 5, stainless steel filter screen, 6, PP cotton filter course, 7, function material layer, 8, blowoff valve, 9, molecular sieve filtration layer, 10, bottom end cover, 11, deflector, 12, Hollow Fiber Ultrafiltration layer, 13, pure water inlet.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail with specific embodiment:

As shown in Figure 1, a kind of compound filtering core of water purifier, including shell 3, upper end cover 1, filter element main body 2 and bottom end cover 10, filter element main body 2 is located in airtight shell 3, upper end cover 1 be respectively provided on two sides with water inlet 4 and pure water inlet 13, bottom end cover 10 is provided with blowoff valve 8, is provided with drainage screen between water inlet 4 and the filter element main body 2 of described upper end cover 1, is provided with the deflector 11 guiding water (flow) direction between filter element main body 2 and described drainage screen. The blowoff valve 8 that bottom end cover 10 is arranged below, it is possible to stainless steel filtering net intercepts the silt got off and Organic substance for recoiling.

In the present embodiment, described drainage screen is stainless steel filter screen 5. Described filter element main body 2 is made up of at least three layers filter material, and its ground floor filter material is PP cotton filter course 6, and second layer filter material is magnetization or infrared function material layer 7, and third layer is NF membrane, RO film or Hollow Fiber Ultrafiltration layer 12. Described filter element main body 2 pottery or composite molecular screen filter course 9 are arranged below. This utility model compact conformation, volume are little, and filtration, purification is effective, easy to assembly fast, be particularly well-suited to portable or mobile water purifier.

Above-described embodiment is only limitted to design of the present utility model and technical characteristic are described, its object is to the technical scheme and the embodiment that allow those skilled in the art understand utility model, can not limit protection domain of the present utility model accordingly. Every equivalent replacement made according to technical solutions of the utility model or equivalence change, all should be encompassed within protection domain of the present utility model.
