Description
Technical field
The utility model relates to a kind of purifier of family expenses, has particularly related to a kind of running water fore filter be arranged at wet part front end.
Background technology
The water supply line in city is outmoded and very long, the impurity such as corrosion, silt of pipeline not only can cause brown water and water equipment to control malfunctioning, as tap drip, heat-exchanger pipeline blocking, break, and impurity can precipitate on pipeline, hotbed is provided on the one hand for growing of bacterium, on the other hand can form electric compound matter, they can in a few short months in cause corrosion or the perforation of metallic conduit.Running water fore filter is the first coarse filtration equipment to full room water, can silt in Filtered tap water, iron rust, large particulate matter.But when impurity is after running water fore filter filters, impurity can be intercepted on the stainless steel filtering net of filter screen inboard wall of skeleton, and after long-time use, impurity can block stainless steel filtering net.
Utility model content
The utility model, for the shortcoming of the filter screen not easy cleaning of running water fore filter in prior art, provides a kind of new filter gauze cleaning mode.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Running water fore filter, comprise copper body, copper body lower end connector drum, be provided with filter screen skeleton in cylindrical shell, filter screen inboard wall of skeleton is provided with filter screen, comprises central tube, central tube passes from filter screen skeleton and filter screen, central tube one end is provided with knob, and central tube has hole, central tube other end connection sealing element.When current are flowed out by central tube, can form vacuum state in filter screen skeleton, central tube and filter screen skeleton can form differential water pressures, by turning knob, drive central tube to rotate, can make the impurity sucking-off be arranged in the filter screen on filter screen skeleton.
As preferably, copper body is provided with water inlet, delivery port and through hole, and water inlet is communicated with copper external body and copper body central authorities, and central tube passes from through hole.When switch closes, raw water flows in filter screen skeleton from copper body water inlet, by flowing out from delivery port after filter screen and filter screen skeleton.
As preferably, seal lower end is provided with switch, and seal is communicated with central tube and switch.After opening switch, the water in central tube is by flowing out running water fore filter after seal.
The utility model, owing to have employed above technical scheme, has significant technique effect:
When switch closes, current flow in filter screen from copper body water inlet, after strainer filtering, flow out running water fore filter from copper body delivery port.Switch is opened during cleaning, pass through turning knob, drive central tube rotates, current are discharged by central tube, seal and switch, when current are flowed out by central tube, central tube and filter screen skeleton can form differential water pressures, and central tube opening part can produce very strong suction, center of rotation pipe can make to be arranged on the impurity sucking-off in filter screen inboard wall of skeleton upper filter screen, is discharged by current.The utility model, by simple operations, can realize the effective cleaning to filter screen in running water fore filter.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
Running water fore filter, comprise copper body 2, copper body 2 lower end connector drum 6, be provided with filter screen skeleton 4 in cylindrical shell 6, filter screen skeleton 4 inwall is provided with filter screen, comprises central tube 3, central tube 3 passes from filter screen skeleton 4 and filter screen, central tube 3 one end is provided with knob 1, central tube 3 has hole 12, central tube 3 other end connection sealing element 5.When current are flowed out by central tube 3, central tube 3 and filter screen skeleton 4 can form differential water pressures, by turning knob 1, drive central tube 3 to rotate, can make the impurity sucking-off be arranged in the filter screen on filter screen skeleton 4.
As preferably, copper body 2 is provided with water inlet 9, delivery port 11 and through hole 10, and water inlet 9 is communicated with that copper body 2 is outside and copper body 2 is central, and central tube 3 passes from through hole 10.When switch 8 closes, raw water flows in filter screen skeleton 4 from copper body 2 water inlet 9, by flowing out from delivery port 11 after filter screen and filter screen skeleton 4.
As preferably, seal 5 lower end is provided with switch 8, and seal 5 is communicated with central tube 3 and switch 8.After opening switch 8, the water in central tube 3 is by flowing out running water fore filter after seal 5.
The utility model, owing to have employed above technical scheme, has significant technique effect:
When switch closes, current flow in filter screen from the water inlet 9 of copper body 2, after strainer filtering, flow out running water fore filter from the delivery port 11 of copper body 2.Open switch 8 during cleaning, by turning knob 1, drive central tube 3 to rotate, current are discharged by central tube 3, seal 5 and switch 8.When current are flowed out by central tube 3, central tube 3 and filter screen skeleton 4, filter screen can form differential water pressures, and central tube 3 opening part can produce very strong suction, and center of rotation pipe 3 can make to be arranged on the impurity sucking-off in filter screen skeleton 4 inwall upper filter screen.The utility model, by simple operations, can realize the effective cleaning to filter screen in running water fore filter.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
