Description
Technical field
Technical field of water purification is the utility model is related to, more particularly to a kind of tube-in-tube composite filter element.
Background technology
In the related art, purifier is used as preposition filter core and then RO filter cores of connecting again using PP cottons, activated carbon etc.
The water system connected Deng composition by multi-stage filter core, carries out the purified treatment of water.The connection of whole system pipeline is complicated, installation and replacement
Inconvenience, polylinker connection, leak risk point are more.Importantly, the service life of multi-stage filter core is inconsistent, consumer needs more
The filter core changed has three to as many as Pyatyi, it is necessary to frequently buy filter core and need to be replaced by the installation personnel of specialty, consumer
Experience it is poor, synthesis it is of high cost.Different quality demand is directed at the same time, can not quick-replaceable.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model proposes a kind of simple in structure, fast changeable internal layer filter core, can
To replace the tube-in-tube composite filter element of internal layer filter core at any time according to different quality.
To solve this technical problem, the utility model takes following scheme：A kind of tube-in-tube composite filter element, including first
Shape filter core and the second tubular element, first tubular element and the second tubular element both ends are respectively equipped with upper end cover and lower end
Lid, the first tubular element center offers coaxial through-hole, the upper end cover and bottom end cover lateral wall of second tubular element
The upper elastic seal ring for being embedded with more than a circle and part protrusion lateral wall respectively, the upper end cover of second tubular element is with
The outside diameter that end cap is embedded elastic seal ring is adapted with the upper end cover of the first tubular element and the internal diameter of bottom end cover respectively, and described
Two tubular elements removably arranged on the first tubular element coaxial through-hole in and the second tubular element upper end cover and bottom end cover
Through the elastic seal ring upper end cover with the first tubular element and the dismantled and assembled connection of bottom end cover inner wall respectively.
Further to improve, the upper end cover and bottom end cover of second tubular element are embedded with two circle elastic packings respectively
Circle.
Further to improve, first tubular element is active carbon filter core, and second tubular element is scale inhibition filtrate
With nanofiber mixing filter core.
By using preceding solution, the beneficial effects of the utility model are：By by arranged on the second tubular of internal layer
The upper end cover and bottom end cover lateral wall of filter core are arranged elastic seal ring, and can by multilayer elastic sealing ring by the second tubular element
Dismounting is nested in the coaxial through-hole of the first tubular element, and the first tubular element and the second tubular element use elastic seal ring
Crush seal is nested, so that consumer can be in the second tubular element of internal layer according to self-demand dismounting at any time, and
Dismountable when removing heavy metals, sterilization, scale inhibition function can need to be such as gone to replace in different according to the water quality difference of each region
The second tubular element of layer or disassemble the second tubular element be only used only the filtering of one layer of the first tubular element also can, when replacement, is fast
It is fast easy, and its is simple in structure, can wide popularization and application.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Embodiment
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to figure 1, the tube-in-tube composite filter element of preferable the utility model, including the first tubular element 1 and the second tubular
Filter core 2, first tubular element 1 are active carbon filter core, and second tubular element 2 mixes for scale inhibition filtrate and nanofiber
Filter core, second tubular element 2 can remove heavy metal, scale inhibition and sterilization, 1 and second tubular element 2 of the first tubular element
Both ends are respectively equipped with upper end cover 11,21 and bottom end cover 12,22, and 1 center of the first tubular element offers coaxial through-hole, institute
State the bullet for being embedded with two circles and part protrusion lateral wall on 22 lateral wall of upper end cover 21 and bottom end cover of the second tubular element 2 respectively
Property sealing ring 3, the upper end cover 21 and bottom end cover 22 of second tubular element 2 are embedded the outside diameter of elastic seal ring 3 respectively with
The upper end cover 11 of one tubular element 1 and the internal diameter of bottom end cover 12 are adapted, and second tubular element 2 is removably arranged on first
In the coaxial through-hole of tubular element 1 and the upper end cover 21 of the second tubular element 2 and bottom end cover 22 through elastic seal ring 3 respectively with the
The upper end cover 11 of one tubular element 1 and the dismantled and assembled connection of 12 inner wall of bottom end cover.
The elastic seal ring being embedded in the utility model on the upper end cover and bottom end cover of the second tubular element is enclosed with 2 circles -4
It is good, the second tubular element can also be PE filter cores, PP melt-blown filters etc. other.
The utility model arranged on the upper end cover of the second tubular element of internal layer and bottom end cover lateral wall by will be arranged elasticity
Sealing ring, and the second tubular element is passed through into the removable coaxial through-hole for being nested in the first tubular element of multilayer elastic sealing ring
Interior, the first tubular element is nested using elastic seal ring crush seal with the second tubular element, so that consumer can be at any time
According to second tubular element of the self-demand dismounting in internal layer, and weight can need to be such as removed according to the water quality difference of each region
Metal, sterilization, the scale inhibition Dismountable when function replace different the second tubular elements of internal layer or disassemble the filter of the second tubular
Core be only used only the filtering of one layer of the first tubular element also can, when replacement, is fast and convenient, and its is simple in structure, and can be widely popularized should
With.
