Description

A kind of water treatment filter flask

Technical field

The present invention relates to the water treatment facilities technical field, relate in particular to a kind of water treatment filter flask.

Background technology

At present, the exhalant canal of water treatment filter flask adopts tubular structure usually:

See also Fig. 1; It is the water treatment filter flask structural representation of tubular structure in the prior art; It comprises enclosing cover 01, inner cap 02, end cap 03, shell 04 and filter core 05; Water inlet arrives gap 041 between shell and the filter core by the flow through outer side clearance 024 of inner cap body and the outer side clearance 033 of end cap body of enclosing cover inlet opening 011, is filtered by 05 pair of water of filter core then, filters good water and is flowed out by outlet pipe 07 that is communicated with end cap 03 and inner cap 02 and enclosing cover apopore 012.Outlet pipe 07 may make water outlet mix mutually with water inlet owing to the leakage of bonding not firm generation water with end cap 03 junction.Be mixed with unfiltered water in the feasible filtered water, influenced water purification water quality through filter element filtering by 012 outflow of enclosing cover apopore.

A kind of water treatment filter flask need be provided, make water inlet can not mix, thereby realize the quality of fully filtering, guarantee purify back water of filter flask water with water outlet.

Summary of the invention

Technical problem to be solved by this invention provides a kind of water treatment filter flask, realizes that the filter flask water inlet separates with exhalant canal fully, reaches the into isolation of water and water outlet, thereby overcomes the defective that water inlet of the prior art and water outlet possibly mix.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:

A kind of water treatment filter flask comprises the enclosing cover that is provided with inlet opening and apopore, is installed in inner cap under the enclosing cover, revolves the molten shell that is connected with the end plate outer rim of inner cap, is arranged in the shell and with the gapped filter core of shell, filter core one end the bottom end plate, the filter core other end that are arranged at outer casing bottom is installed end cap is installed; After the assembling; Form intake tunnel via gap between enclosing cover inlet opening, space, the inner cap body outside, space, the end cap body outside, shell and the filter core; Via end cap body inside, inner, the enclosing cover apopore formation exhalant canal of inner cap body, end cap body upper end extends to inner cap body bottom and revolves molten the connection with it.Inner cap revolves with end cap and molten the connection makes intake tunnel and exhalant canal isolate fully.

Filter core of the present invention is that PP is cotton, and bottom end plate coats filter core one end.The water that need to purify is by the intake tunnel PP cotton of flowing through, and water arrives exhalant canal after through the cotton filtration of PP.

Filter core of the present invention comprises ABS body and the granular activated carbon or the milipore filter that are arranged in the ABS body, and the bottom end plate bottom is provided with through hole.The water that need to purify is by the through hole of intake tunnel and bottom end plate bottom flow through granular activated carbon or milipore filter, and water arrives exhalant canal after passing through the filtration of granular activated carbon or milipore filter.

Adopt the beneficial effect of technique scheme:

The inner cap that the present invention adopted directly revolves molten the connection with end cap; Make the intake tunnel that forms via gap between enclosing cover inlet opening, space, the inner cap body outside, space, the end cap body outside, shell and the filter core with inner via the end cap body, the inner cap body is inner, the exhalant canal of enclosing cover apopore formation separates fully; Realize the isolation of water inlet and water outlet, thereby reach filter flask the effect of filtering fully of water, the quality that guarantees to filter back water.
