Abstract
The utility model provides a filter core of a water purifier, which is composed of an upper press plate, upper fiber filter materials, an upper supporting frame, a lower supporting frame, lower fiber filter materials, a lower press plate, a core pipe and a shell, wherein the upper supporting frame, the lower supporting frame, the core pipe and the shell are assembled into a non-removable whole and a cavity is formed in the middle part of the whole. Through holes are arranged on the upper supporting frame and the lower supporting frame, and the side wall of the core pipe is provided with a through hole. Because filtration is carried out by a filter core of the fiber filtering materials and an upper and a lower fibre filter cores simultaneously, filtering areas are raised under the precondition of no reduction of filtration accuracy, and thus water-outlet flow quantity can be increased and cleaning period can be prolonged.
Description
Technical field
The utility model relates to a kind of filter element of water purifier, the fiber filtering filter core that particularly a kind of water purifier is used.
Background technology
Filter element of water purifier be installed in usually with the matching used bucket of water purifier in, make the running water enter bucket through behind the filter element filtering, become water capable of direct drinking.Existing filter core is generally one-sided or single-sided structure, and water (flow) direction is from the top down, and when the filtration required precision was higher, filter core stopped up easily, needs often to clean troublesome maintenance; When the filtration precision was low, though then resistance to water-flow is less, water flow was bigger, was difficult for stopping up, and the cleaning frequency is longer, and maintenance is simple, and the water quality after filtering is relatively poor.This has just produced a pair of contradiction between filtering accuracy and filter efficiency.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and has the water purifier fiber filtering filter core than high filtering precision and filter efficiency.
The utility model provides a kind of filter element of water purifier, and this filter core reaches the bottom at an upper portion thereof and comprises fiber filtering and following fiber filtering respectively, also can load other filtrate between the fiber filtering up and down.This filter core is by top board, goes up fiber filtering, upper support frame, lower support frame, following fiber filtering, lower platen, core pipe and housing are formed, upper support frame, lower support frame, core pipe, housing are assembled into a non-removable integral body, form a cavity in the middle, last fiber filtering, top board are installed on the upper support frame, following fiber filtering, lower platen are installed on the lower support frame, on upper support frame, the lower support frame through hole are arranged, and the sidewall of core pipe has through hole.
In addition, on core pipe top through hole is arranged, diaphragm, return-air lid are arranged on through hole top, return-air lid, diaphragm and core pipe are formed a check device.In filter core, be filled with filtrate in the cavities.
Upper support frame and core pipe are preferably same part in addition.Lower support frame and core pipe also are same part.Soon the core pipe extends respectively and becomes upper support frame and lower support frame.
Water purifier fiber filtering filter core provided by the utility model because upper and lower fabric filter element filters simultaneously, adopts the double-side fibre filter structure, under the prerequisite that does not reduce filtering accuracy, improves filter area, increases water flow with this, prolongs the cleaning frequency.
Description of drawings
Fig. 1 is the utility model filter cartridge construction schematic diagram;
Fig. 2 is for adopting water purifier current, the air-flow principle schematic of the utility model filter core.
The specific embodiment
Be described in detail of the present utility model below in conjunction with concrete accompanying drawing, but be to be understood that the detailed description does not here constitute the restriction to the utility model protection domain.
Fig. 1 is the utility model filter cartridge construction schematic diagram.Filter element of water purifier provided by the utility model as seen from the figure, be by top board 5, last fiber filtering 15, upper support frame 6, lower support frame 8, following fiber filtering 16, lower platen 9, core pipe 4 and housing are formed, upper support frame 6, lower support frame 8, core pipe 4, housing is assembled into a non-removable integral body, form a cavity in the middle, last fiber filtering 15, top board 5 is installed on the upper support frame 6, following fiber filtering 16, lower platen 9 is installed on the lower support frame 8, upper support frame 6, on the lower support frame 8 through hole is arranged, the sidewall of core pipe has through hole, is respectively apopore 11 and steam vent 12.
In addition, on core pipe top through hole is arranged, promptly core pipe steam vent 13 has diaphragm 3, return-air lid 2 on through hole top, and return-air lid 2, diaphragm 3 and core pipe 4 are formed a check device.On return-air lid 2, have through hole, be respectively return-air lid osculum 20 and return-air lid steam vent 21.
In filter core, be filled with filtrate 7 in the cavities, following silk screen 17 and last silk screen 18 arranged respectively at the upper and lower of filtrate 7.
Upper support frame 6 and core pipe 4 are same part in addition.Lower support frame 8 and core pipe 4 also are same part.Soon core pipe 4 extends respectively and becomes upper support frame 6 and lower support frame 8.In addition, at the core tube outer surface groove is arranged, the inner wall surface of groove has screw thread 14, so that be connected with last bucket.
Be covered with filter core cover 1 on whole filter core top, on the filter core cover, have through hole, be i.e. filter core cover inlet opening 19, filter core cover steam vent 22.
Lower support frame 8 forms a non-removable integral body when the injection moulding by silk screen 10 and working of plastics, after also can working of plastics being shaped, silk screen 10 is bonded on the working of plastics again.
Fig. 2 is current air-flow principle schematic in the water purifier that adopts the utility model filter core.Moisture on the water purifier in the bucket is two-way, wherein one road current pass top board, upward fiber filtering enters the particulate filter space, and another road current pass lower platen, following fiber filtering, enter the particulate filter space, behind aforementioned current interflow, discharge from core pipe apopore again and enter lower filter.The current that original air is entered in the particulate filter are extruded simultaneously, discharge from filter core steam vent 12 and steam vent 13.Back down diaphragm 3 again, pass return-air lid steam vent 21, filter core cover steam vent 22, the water that passes again in the bucket enters atmosphere.Like this, the air in the filter core is drained substantially, and current are smooth and easy, and filter process is stable.After air in the filter core drained, diaphragm 3 was under the hydraulic pressure effect on gravity own and diaphragm 3 tops, and general who has surrendered's steam vent 13 seals under the diaphragm.That is to say, diaphragm 3 and steam vent 13 formed one only allow air-flow upwards by and do not allow the check valve that passes through under the current direction, this has just guaranteed that all current all must elder generation's process fiber filtering filtration enter into the particulate filter space again, could flow into lower filter then.
Water purifier fiber filtering filter core provided by the utility model because upper and lower fiber filtering 15 and 16 filters simultaneously, adopts the double-side fibre filter structure, under the prerequisite that does not reduce filtering accuracy, improve filter area, increase water flow, prolong the cleaning frequency with this.
