Technical field

The utility model is about the filter core of water filter, is meant especially a kind ofly to cooperate relevant pipeline and produce the variform filter cartridge construction of cleaning function voluntarily.

Background technology

The water filter filter cartridge construction that present common filter effect is preferable, as shown in Figure 1, be provided with (metal) cortina 71 of several bendings that take the shape of the letter U in its urceolus 7, and the mode that makes these several cortinas 71 be dense arrangement is placed in this urceolus 7, and these urceolus 7 table sides are respectively equipped with a water inlet 72 and a delivery port 73 along orientation two ends of this cortina 71; Current to be filtered enter urceolus 7 by water inlet 72, and via the impurity that each cortina 71 filters in these current, clean water is flowed out by the delivery port 73 of the other end.

Yet, along with impurity builds up, not only can block the space of 71 of each cortinas, simultaneously the filter effect of this cortina 71 is reduced gradually, unless periodic replacement, otherwise can influence the quality of the smooth and easy and drainage of current; Therefore, the general replacement filter core just becomes water filter and use to go up maximum cost burden, how can effectively prolong the service life of filter core and does not reduce its drainage quality, to reduce the use cost of water filter, just becomes the required improved technology of related personnel.

Novel content

Main purpose of the present utility model is to provide a kind of filter cartridge construction of water filter, and it can clean filter core inside according to need automatically, to reach the service life that prolongs this filter core, the effect of guaranteeing filter quality.

Another purpose of the present utility model is to provide a kind of filter cartridge construction of water filter, and it can select different filter core cleaning models according to need, implements inner the cleaning with the pattern that suits the requirements most, reaches best economic benefit.

The technical solution of the utility model comprises: a housing, and it is a hollow container, and its biend is respectively equipped with a water nozzle and a pure water inlet altogether, and this housing stage casing periphery is provided with a water inlet and an outlet of sewer; One cortina is placed in this housing by tight arrangement of several silk thread sections, and two ends of this cortina extend to the shared mouth of a river and the interior side of pure water inlet of housing respectively; The water inlet of this housing can import water and flow in the housing, behind this current organizine membrane filtration, derive by this shared mouth of a river and pure water inlet, after also can making these current clean enclosure interior, discharge by outlet of sewer, this shared mouth of a river can import water in addition and flow in the housing, and cleaning this cortina, and the sewage of this cleaning cortina can be discharged by outlet of sewer.

The specific embodiment

Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing:

See also shown in Fig. 2-3, the filter cartridge construction of water filter described in the utility model mainly comprises: housing 1, cortina 2, wherein, this housing 1 is the hollow container of a strip, its biend is respectively equipped with a water nozzle 11 and a pure water inlet 12 altogether, and be provided with a water inlet 13 and an outlet of sewer 14 in housing 1 stage casing periphery, cortina 2 is closely arranged by several silk thread sections and is formed, it is placed in this housing 1, and two ends of this cortina 2 extend to the shared mouth of a river 11 and the pure water inlet 12 interior sides of housing 1 respectively.

See also shown in Figure 4, the filter cartridge construction of water filter described in the utility model is when reality is used, establish a three-way connection 3 at the water inlet 13 of this housing 1, first joint of this three-way connection 3 directly is connected an oral siphon 33, its second joint is incorporated into the water inlet 13 of this housing 1 via one first control valve 31, the 3rd joint of this three-way connection 3 is provided with one second control valve 32, the shared mouth of a river 11 of this housing 1 is incorporated into first valve port of a three-way control valve 4, second valve port of this three-way control valve 4 connects via a bypass pipe 41 to be held in the mouth in this second control valve 32, the 3rd valve port of this three-way control valve 4 is connected a pure water pipe 42, the outlet of sewer 14 of housing 1 directly combines with a sewage control valve 5, this pure water inlet 12 combines with a water purification control valve 6, and this water purification control valve 6 is communicated with described pure water pipe 42 via a pure water pipe 61;
