Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to make technical solution of the present invention, purpose and its advantage more clearly
Explanation is further explained in the present invention.
As shown in Figures 1 to 4, a kind of filter assemblies of the invention, comprising:
Filter material mould group 2, setting application is RO membrane structure, and raw water input terminal 21 is set to top side position, and waste water is defeated
Outlet 22 is set to bottom side and periphery side position, and inside is the pure water side that pure water generates, which, which is extended, center
It manages and guides to the top side position of the filter material mould group 2, to be formed with the pure water output end 23 externally exported for the pure water;
Mouth of a river attachment base 3 is set to 2 top side of filter material mould group;It is defeated that the raw water is corresponded on the mouth of a river attachment base 3
Enter to hold 21 to be provided with original water inlet 31, the corresponding pure water output end 23 is provided with pure water outlet 32;
Filter material mounting base 4 is set to 2 bottom side of filter material mould group, and the filter material mounting base 4 includes pedestal 41, described
The installation cavity 42 for filter material mould group 2 described in attaching is provided on pedestal 41,42 bottom of installation cavity corresponds to the filter material mould
The waste water output end 22 of 2 bottom sides of group is provided with waste water interface 43, and 41 bottom side of pedestal corresponds to 43 position of waste water interface and prolongs
It stretches and is provided with valve mounting portion 44, the valve installation cavity 42 being connected to the waste water interface 43, institute are formed on the valve mounting portion 44
State the wastewater outlet 45 for being provided on valve mounting portion 44 and being connected to the valve installation cavity 42;It is arranged in the valve installation cavity 42
There is the unidirectional water guide valve 5 for guiding waste water unidirectionally to flow to from the waste water interface 43 wastewater outlet 45.
The unidirectional water guide valve 5 includes valve body 51, and 51 peripheral side of valve body is arranged with valve waterproof washer 52, and the valve is anti-
Water cushion circle 52 and the valve installation cavity 42 are interference fitted;Its top side is provided with inlet 53 to the valve body 51 and its bottom side is arranged
There is liquid outlet 54;The valve chamber 55 being connected to the inlet 53 and the liquid outlet 54, the valve are provided in the valve body 51
The water bloking piece 56 for being closed the inlet 53 is provided in chamber 55, between the water bloking piece 56 and the bottom of the valve chamber 55
It is connected with spring 57, the spring 57 is applied with the reseting elasticity towards inlet 53 to the water bloking piece 56;When waste water is flow to
When 53 position of inlet of top side, under gravity, waste water is pushed water bloking piece 56 open and is entered in valve chamber 55, and guides extremely
The liquid outlet 54 is externally discharged;And external aqueous is then stopped by the water bloking piece 56 for being closed to the inlet 53.
2 bottom side of filter material mould group is provided with positioning column 24, and it is fixed that 42 lower center position of the installation cavity sinking is provided with
Position slot 46, the positioning of positioning column 24 are secured on the locating slot 46;42 bottom of installation cavity has circumferentially been uniformly arranged more
A module support block 47 for being supported to the filter material mould group 2, the waste water interface 43 are set to two adjacent mould groups
Between supporting block 47, table side and 43 position of waste water interface have height difference on the module support block 47;Pass through the positioning column
24 are equipped with locating slot 46, to meet the needs of positioning of filter material mould group 2 is assemblied in the filter material mounting base 4.
Its application principle is as follows:
By the setting of the filter material mounting base 4, the waste water energy that 2 bottom side of filter material mould group of its attaching is discharged directly via
The unidirectional water guide valve 5 discharges, and the waste water after discharge cannot then be returned via the wastewater outlet 45 of bottom side again seeps back filter material mould group 2
In, to effectively avoid the high TDS Solute accumulation of bottom side waste water output end 22 and penetrate into pure water side.
And the application has the filter assemblies of filter material mounting base 4 to be arranged, and can make the filter material mould group 2 RO film in the prior art
Structure is applied, to have good versatility, meets the practical application request in market.
The invention also includes a kind of filter cartridge constructions comprising with inner cavity shell 1,1 top of shell be provided with
Raw water mouth 11, pure water mouth 12 and the waste water mouth 13 of inner cavity connection are provided with above-mentioned band filter material mounting base 4 in the inner cavity
Filter assemblies, then the raw water mouth 11 of the filter cartridge construction and the original water inlet 31, the pure water mouth 12 and pure water outlet
32 immediately connection cooperations;The lower center position of the inner cavity corresponds to 46 position of locating slot of the sinking setting to set
It is equipped with the modular support block 14 for being supported to the filter assemblies, table side and the inner cavity on the modular support block 14
Bottom between have spacing, be formed be between the wastewater outlet 45 and the bottom of the inner cavity for cache it is useless
The water space 15 of water;It is formed between the filter assemblies peripheral side and the side wall of the inner cavity and is connected to the water space 15
And the waste water runner 16 of waste water mouth 13.
Its application principle is as follows:
It is arranged by corresponding water space 15, the waste water being discharged on the downside of the filter assemblies is made to can be carried out interim delay
It deposits, waste water is avoided to be accumulated in the inner cavity bottom side of the filter cartridge construction, and bottom side waste water further can effectively be avoided to export
The high TDS Solute accumulation at end 22 simultaneously penetrates into pure water side.
The application of filter material mould group 2 is RO membrane structure form, then the waste water of its periphery side position of filter assemblies discharge
And the waste water of bottom side position discharge synergistically can be emitted into waste water mouth 13 in the waste water runner 16 and is discharged, and make the filter core
Structure has the technical characterstics such as application is efficient, structure is simple.
And pass through raw water mouth 11, waste water mouth 13 and pure water mouth 12 uniformly centralized arrangement, in order to pacify in the filter cartridge construction
Dress uses, and meets the practical application request in market.
The foregoing is merely the preferred embodiment of the present invention not to depart from this for those skilled in the art
Under the premise of the implementation principle of invention, it can still modify to the embodiment, and corresponding modification also should be regarded as this hair
Bright protection scope.
