The specific embodiment

, be described in detail as follows detailed construction of the present utility model, application principle, effect and effect below in conjunction with accompanying drawing:

Please refer to Fig. 2-5, can clearly find out, the utility model mainly comprises: filter core body 1, filter cartridge seat 2, go into water valve 3, outlet valve 4, middle control valve 5 and draining valve 6 etc. are partly, wherein, this filter core body 1, filter cartridge seat 2 can be combined into a filter core unit, be provided with a blasthole 11 and an apopore 12 in a distolateral surface of this filter core body 1, being separated in this in its inside with a filter material 16 goes into, apopore 11, between 12, make this first space 14 that is communicated with blasthole 11 of filter core body 1 inner formation, and second space 15 that is communicated with apopore 12, the other end on this filter core body 1 surface is provided with an osculum 13, the surface of filter cartridge seat 2 is provided with a water inlet 21 and a delivery port 22 is gone into this respectively,

apopore

11,12 are connected connection mutually, go into water inlet 21 outsides that water valve 3 is arranged at this filter cartridge seat 2, and be connected in the water source via a preceding three-way connection 31, outlet valve 4 is held in the mouth delivery port 22 outsides in this filter cartridge seat 2 via three-way connection 41 after, middle control valve 5 is connected in the 3rd joint 311 of this preceding three-way connection 31 and the 3rd joint 411 of this back three-way connection 41, and this draining valve 6 is arranged at osculum 13 outsides of this filter core body 1.

During use, if close this centre control valve 5, draining valve 6, open water valve 3, outlet valve 4, the current that then can control external water source are flowed into first space 14 of filter core body 1 by water inlet 21, blasthole 11, these current flow into second space 15 after filtering its impurity via filter material 16, outwards flowed out by outlet valve 4 by apopore 12, delivery port 22, this is a water supply filtration cycle (as shown in Figure 3) again; If close this centre control valve 5, open outlet valve 4, go into water valve 3, draining valve 6, then the current of external water source flow into first space 14 of filter core body 1 according to aforesaid paths, directly discharge through draining valve 6 by osculum 13 again, this can form one clean filter material 16 outer circumferential sides along washing circulation (as shown in Figure 4); Go into water valve 3, outlet valve 4 when closing this, control valve 5, draining valve 6 in the middle of opening, then the current of external water source can by preceding three-way connection 31 through middle control valve 5, after three-way connection 41 and import second space 15 of filter core bodies 1 by this

delivery port

22,12, first space 14 that arrives by filter material 16 (taking the impurity in the filter material 16 simultaneously out of) again, sewage after this cleans is discharged by draining valve 6 through osculum 13, to form back washing circulation (as shown in Figure 5); By above-mentioned along wash, circulation such as back washing, can effectively remove the impurity that accumulates in the filter core body 1, increasing its service life, and in this cleaning process, this filter core body 1, filter cartridge seat 2 need not can implement above-mentioned cleaning way by pulling down in the pipeline, have operational convenience.

From the above mentioned content as can be known, filter core and the cleaning device thereof of the utility model water filter have really Easy and simple to handle and can increase service life, reduce the effect of use cost.
