Description

A kind of filter screen type filter core

Technical field

The present invention relates to the clean technologies field, relate in particular to a kind of filter screen type filter core.

Background technology

The daily running water of drinking is through multiple clean, sterilization and sterilization means, through dispatching from the factory, water quality detection all can reach state health standards, but before flowing into resident family, can first pass through complicated landform and road, because some pipeline is long neglected and in disrepair, water pipe intersects with sewage pipe, some water pipes in building even first will be through lavatory, the seepage of water pipe surrounding, many reasons such as iron rust that the secondary pressurized water tank is seldom cleared up in sterilization and water pipe can cause the secondary pollution of water quality, one detect again, iron rust, plumbous, phenol, agricultural chemicals has appearance in various degree, its pollution condition may be startling, long-term drinking likely becomes calculus, the pathogenic factor of the diseases such as cardiovascular and artery sclerosis.

Water purifier is as a kind of purifier, very popular, the function of water purifier is mainly removes heavy metal in water, bacterium, virus, chlorine residue, smell flavor, heterochromatic, agricultural chemicals, floating thing, iron rust, sandstone, colloid and micron-sized impurity, filter ruffle is as one of core component of water purifier, prolongation along with service time, inner impurity can be cumulative, performance starts to reduce, filter efficiency starts to descend, therefore in use for some time, the water purifier filter ruffle will be changed in time, how to prepare a kind of long service life, filter efficiency is high, filter ruffle cost-saving and that can need not change for a long time becomes technical problem urgently to be resolved hurrily at present.

Summary of the invention

The present invention is in having proposed a kind of filter screen type filter core, and this filter screen type filter element filtering efficiency is high, splits combined and instant, and the water purifier of preparation is longer service life, and can need not change inner filter core for a long time.

A kind of filter screen type filter core, comprise inner sleeve, establishes the first cavity and be communicated with outside inner sleeve and at least one group of the first through hole of the first cavity;

Overcoat, the socket inner sleeve, be provided with the second cavity and be communicated with outside overcoat and at least one group of the second through hole of the second cavity;

Filtering net, coordinate around outer wall of inside race;

Outer screen pack, coordinate around outer casing outer wall.

Preferably, inner sleeve one end is provided with the first outer back-up ring, and the first outer back-up ring is in the overcoat far-end, and overcoat one end is provided with the second outer back-up ring, and the second outer back-up ring is in the inner sleeve far-end, and outer screen pack chucking is between the first outer back-up ring and the second outer back-up ring.

Preferably, be provided with the first inner shield ring and second inner shield ring of chucking filtering net at the inner sleeve two ends.

Preferably, the first inner shield ring and the second inner shield ring coordinate with outer casing inner wall.

Preferably, the first outer back-up ring contacts the first inner shield ring, and the second outer back-up ring contacts the second inner shield ring.

Preferably, overcoat or inner sleeve end are provided with installing hole.

Preferably, mounting hole site stretches into an end of overcoat in inner sleeve.

A kind of purifier, comprise described filter ruffle.

In the present invention, by outer wall of inside race, filtering net being set, outer casing outer wall arranges outer screen pack, effectively the particle of certain particle diameter in filtered water; When impurity is accumulated to a certain degree on filter ruffle, filter ruffle can be taken apart, inner filter screen, outer filter, inner sleeve and overcoat are cleaned up, re-assembly use, effectively extend the service life of filter ruffle, reduce cost; Establish the first outer back-up ring interior putting, put outward and establish the second outer back-up ring, outer filter closely can be fixed on to outer casing outer wall, and can avoid occurring the filtration dead angle of outer filter; Establish the first inner shield ring and the second inner shield ring interior putting, inner filter screen can be fitted tightly at outer wall of inside race, and can avoid occurring the filtration dead angle of inner filter screen; Overcoat or in put installing hole be set, filter ruffle is fixed on purifier, in the present invention, the filter ruffle long service life of described purifier, filter efficiency is high, internal structure coordinates closely, disassembly and assembly are convenient, and cost-saving.

The accompanying drawing explanation

Fig. 1 is the cross-sectional view of a kind of filter screen type filter core of proposing of the present invention.

The specific embodiment
