Abstract

The invention discloses a screw filtering assembly for water. The assembly which comprises a filter material (4) and a filter core housing (1) with water inlets (5) and water outlets (2) is characterized in that: a screw inner core (3) is arranged in the filter core housing (1); the outer edge of the screw inner core (3) is tightly attached to the inner wall of the filter core housing (1); and the filter material (4) is placed in the screw inner core (3). The assembly of the present invention has the advantages of simple structure, long penetration approach, and good filtering effect.

Description

Spiral water filtration assemblies

Technical field

The present invention relates to a kind of spiral water filtration assemblies, belong to the water purifier field.

Background technology

At present, in the water treatment facilities of selling on the market, extensively adopt single or multiple filtrate to do filter core, no matter take which kind of media filtration, ubiquity filtration approach is too short, and the media filtration effect can not be given full play to, and its reason is to receive the restriction of filter core size.Chinese patent CN2832266Y discloses a kind of spiral water purification catridge; Be the spiral filter core to be set in filter core main body periphery; The water inlet pipe bottom communicates with the spiral filter core; Spiral filter core top links to each other with the filter core main body through taking over case, and the filter core bottom part body is provided with milipore filter filter core layer, and filter core main body top is provided with exhaust outlet.Though this structure has prolonged former water penetration route, the structure more complicated, manufacturing cost is high.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, provide that simple in structure, penetration route is long, the spiral water filtration assemblies of good filtration effect.

The technical scheme that realizes the object of the invention is: a kind of spiral water filtration assemblies; Comprise filtrate and filter case with water inlet, delivery port; Have spiral inner core in the filter case, the outer rim of spiral inner core and the inwall of filter case fit tightly, and filtrate is placed in the spiral inner core.

Further, filter case is a cylindrical shape, is processed by Elastic plastic-rubber.

Further, spiral inner core is the spiral Open architecture.

After having adopted technique scheme, spiral inner core and filter case are formed one, and spiral inner core inserts filter case; Former water is got into by the water inlet of filter case; Guide function through the spiral inner core through filter material, has increased filtration path along the spiral approach greatly; Can give full play to the filtration of filtrate, the water after filtering is at last flowed out by the filter case delivery port.The present invention is simple in structure, and low cost of manufacture helps on market, promoting.

Description of drawings

Fig. 1 is a sectional structure sketch map of the present invention;

Fig. 2 is the front view of spiral inner core;

Fig. 3 is the vertical view of Fig. 2.

The specific embodiment

For content of the present invention is expressly understood more easily,, the present invention is done further detailed explanation below according to specific embodiment and combine accompanying drawing.

Shown in Fig. 1 ~ 3; A kind of spiral water filtration assemblies comprises filtrate 4 and the filter case 1 with water inlet 5, delivery port 2, has spiral inner core 3 in the filter case 1; The inwall of the outer rim of spiral inner core 3 and filter case 1 fits tightly, and filtrate 4 is placed in the spiral inner core 3.

Filter case 1 is a cylindrical shape, is processed by Elastic plastic-rubber.。

Spiral inner core 3 is the spiral Open architecture.

Operation principle of the present invention is following: spiral inner core 3 is formed one with filter case 1; Spiral inner core 3 inserts filter case 1, and former water is got into by the water inlet 5 of filter case 1, through the guide function of spiral inner core 3; Along the spiral approach through filter material; Increased filtration path greatly, can give full play to the filtration of filtrate, the water after filtering is at last flowed out by filter case delivery port 2.

Above-described specific embodiment; The object of the invention, technical scheme and beneficial effect have been carried out further explain, and institute it should be understood that the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.

Claims
