Abstract

The utility model relates to a filter core with segment filtration. The end part is a pried type cover plate with a plurality of holes. Primary stage filter material is arranged under the cover plate. A fixed partition board with a plurality of holes is arranged under the primary stage filter material. Four edges tightly adhere to the inside wall of the filter core. Active filtering material is loaded in a filter core cavity body under the partition board. The utility model has the function that the water quality can be further filtered. The primary stage filter material can be replaced by users conveniently. The goal that the active filtering material at the lower part is protected can be obtained. The goals that the water quality after filtered can be ensured and the service life of the filter core can be prolonged can be obtained. The utility model has the advantages of simple structure, convenient installation, good purifying effect and long service life and is an optimal filtering core construction for domestic running water purifiers.

Description

Filtering core of domestic water filter

The utility model is a kind of purifying equipment for running water, is that city dweller's household tap water filters articles for use.

Current commercially available household water filter filter core is a closed integral body, the filtration, purification process is all carried out in the sealing filter core, filtering material in the filter core is stain by solid in the running water and colloidal particles easily, cause water purifier to filter the very fast decline of adsorption capacity, not only shorten the service life of filter element of water purifier greatly, and the water quality after the influence filtration, do not reach the water purification requirement.

At above-mentioned shortcoming, the purpose of this utility model provides and a kind ofly can guarantee the water purification quality, can separate again that solid and colloidal particles do not make its family expenses filter element for purifier that stains activated filter film material in filter core, classified filtering structure in the running water.

The utility model is realized by following design:

The top of filter element of water purifier is a slice pryable type Perforated decking (1), and it transfers an inorganic ultra-fine filter pulp (2), act as one-level and just filters, and borrows contained solid and colloidal particles in the distinctive strong adsorptivity filtering running water of filter pulp.Filter pulp is following to be the fixed porous barrier of a slice (3), and all around with filter core cylindrical shell (4) inwall secure bond, filling micropore glass diatomite isoreactivity filtering material (5) act as cascade filtration or multistage filtering in the fixed porous barrier lower cavity.The filter core of the utility model household water filter is organic material such as available plastics not only, and also available metal and inorganic material are made.

Employing the utlity model has following advantage:

One, filter core is the segmentation filtration, thereby guarantees filtrate water quality; Two, the filter material in the primary filter section is easily changed voluntarily by the user, thereby has prolonged the service life of filter core; Three, the utility model is simple in structure, and is easy to use, is the present domestic household water filter filter core that is in first-class top standard.

Fig. 1 is the structural representation of the utility model household water filter filter core.

Among the figure: 1, pryable type Perforated decking; 2, filter pulp; 3, fixed porous barrier; 4, filter core cylindrical shell; 5, activated filter film material; 6, delivery port.

Use is described further to the utility model below in conjunction with accompanying drawing:

The running water that enters filter core is at first by top a slice pryable type cover plate (1), and wherein contained solid and colloidal particles are by filter pulp (2) adsorption filtration; Running water through this filter just passes through fixed porous barrier (3) again, and other wherein contained harmful substance is held back by the further absorption of micropore glass diatomite isoreactivity filtering material (5).In use the user can observe the variable color situation of white filter pulp under the filter core Perforated decking by the water purifier transparent outer cover, gradually by the leucismus Huang, the user can according to circumstances change filter pulp by the pryable type cover plate so that guarantee this filter core one-level unique effect of filter just to filter pulp this moment along with the adsorbance increase.

Claims

The utility model household water filter filter core, mainly by pryable type Perforated decking 1, filter pulp 2, fixed porous barrier 3, filter core cylindrical shell 4, activated filter film material 5 constitutes, the top that it is characterized in that filter element of water purifier is a slice pryable type Perforated decking 1, lay an inorganic ultra-fine filter pulp 2 under it, below filter pulp 2, load onto the fixed porous barrier 3 of a slice, all around with filter core cylindrical shell 4 inwall secure bond, filling micropore glass diatomite isoreactivity filtering material (5) in the fixed porous barrier lower cavity, this filter element of water purifier is organic material such as available plastics not only, also can be inorganic and metal material is made.
