In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of can the Domestic tap water filtration apparatus of backwash, including cylinder, the supporter of O-ring cylinder one end, the obturator of the O-ring cylinder other end, be arranged in cylinder, near obturator and the gripper shoe that keeps at a certain distance away with obturator；It is arranged in cylinder and the tubulose filter element coaxial with cylinder, the three-way diverter valve being installed on supporter, and on and tube wall parallel with tubulose filter element, is provided with the backwash tube of some through holes in being arranged at cylinder；One of them joint of described three-way diverter valve connects water inlet pipe, and two other joint connects with tubulose filter element and backwash tube respectively；Described tubulose filter element and backwash tube seal towards one end of gripper shoe with gripper shoe end contact；Described tubulose filter element and three-way diverter valve junction are provided with the drain pipe of band drain valve；The outlet led between obturator and gripper shoe in interval is set in described gripper shoe, described obturator is provided with outlet pipe.
Preferably, support tubulose filter element and the support ring of backwash tube it are provided with in described cylinder.
Preferably, described gripper shoe is provided with setting-in tubulose filter element and the groove of backwash tube.
Preferably, described tubulose filter element is provided with the 3rd sealing ring with one end of supporter setting-in.
Preferably, described supporter is provided with setting-in tubulose filter element and the groove of backwash tube.
Preferably, the outer rim of described gripper shoe is provided with the first sealing ring.
Preferably, the outer rim of described obturator is provided with the second sealing ring.
Preferably, it is provided with adjustment ring between described obturator and gripper shoe.
Compared with prior art, this utility model has the advantage that
(1) this utility model is easy to use, is not required to existing water pipe being arranged, carrying out transformation can realize purification of water quality；By arranging backwash tube, only need changeover valve, just can realize filter element cleaning, it is not necessary to dismounting, safeguard simple and convenient；
(2) this utility model uses pure physical filtering, only filters impurity, retains mineral, does not lose useful ion component in original water, meet the human body demand to trace mineral；
(3) this utility model is long for service life, and operating cost is low, metal filtering core can Reusability, be greatly reduced family drinking-water spending.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not paying creative work premise, broadly fall into the scope of this utility model protection.
Can the Domestic tap water filtration apparatus of backwash shown in Fig. 1, including cylinder 1, the supporter 2 of O-ring cylinder 1 one end, the obturator 3 of O-ring cylinder 1 other end, it is arranged at cylinder 1 obturator 3 interior, close and the gripper shoe 4 kept at a certain distance away with obturator 3；In being arranged at cylinder 1 and the tubulose filter element 5 coaxial with cylinder 1, the three-way diverter valve 6 being installed on supporter 2, and on and tube wall parallel with tubulose filter element 5, it is provided with the backwash tube 7 of some through holes in being arranged at cylinder 1；One of them joint of described three-way diverter valve 6 connects water inlet pipe 16, and two other joint connects with tubulose filter element 5 and backwash tube 7 respectively；Described tubulose filter element 5 and backwash tube 7 seal towards one end of gripper shoe 4 with gripper shoe 4 end contact；Described tubulose filter element 5 and three-way diverter valve 6 junction are provided with the drain pipe 8 of band drain valve；The apopore 9 led between obturator 3 and gripper shoe 4 in interval is set in described gripper shoe 4, described obturator 3 is provided with outlet pipe 10.
