Description

Water filter

The utility model relates to a kind of filter of water.

The early stage home-use only single filtering element (cartridge) of water filter, the water inlet of water filter are arranged in the water source outlet, allow the intracardiac after filtration filter material of water filter after, change again by the delivery port of below and discharge, this kind filter can only be done preliminary filtration.In recent years, the reverse osmosis filtering technique is applied on the water filter, the reverse osmosis filtration method no doubt can obtain purer water, yet it must be by the high pressure that continues, could allow the water that enters to filter by reverse osmosis membrane, not only price is comparatively expensive, and just only have an appointment 25% the amount of obtaining of the water yield of filtering that enters, be that all the other water of 75% all are taken as waste water and drain, and this water in 75% is not to be all the water that contains impurity, but also having little time through under the filter, just, caused the water resource significant wastage by the discharge of extruding of the water of follow-up high pressure.

The purpose of this utility model aims to provide a kind of filter element apparatus with three filtering element (cartridge)s, and filter effect is identical with the reverse osmosis water filter, and low cost of manufacture, long service life.

The utility model comprises housing, three filtering element (cartridge), loam cake and water inlet pipe and water outlet pipes that are communicated with in regular turn, first filtering element (cartridge) is a cylindrical shell, last side opening is established filter lid, and the cylindrical shell upper end is established a pipeline and is communicated with water inlet pipe on the housing, establishes filter pulp on cylindrical shell is interior, filter pulp downside central authorities establish the hollow mesentery, hollow mesentery periphery is outer ring water channel, and outer ring water channel is established the pipeline water pipe that runs in, and the inlet that pipeline is connected to second filtering element (cartridge) is established in the outlet of hollow mesentery central water channel.Second filtering element (cartridge) is a cylindrical shell, fills the different filter materials that (contain 2 layers) more than 2 layers in the cylindrical shell, and the place establishes filter pulp in the cylindrical shell gateway, and the inlet that pipeline connects the 3rd filtering element (cartridge) is established in the exit.The 3rd filtering element (cartridge) is a cylindrical shell, fills the different filter materials that (contain 2 layers) more than 2 layers in the cylindrical shell, and the place establishes filter pulp in the cylindrical shell gateway, and the exit is established pipeline and picked out water pipe.

Fig. 2 is the utility model STRUCTURE DECOMPOSITION figure.

Fig. 3 is the utility model filtering element (cartridge) action schematic diagram.

By embodiment structure of the present utility model and effect are elaborated below.

Referring to Fig. 1 to Fig. 3, the utility model is that 3 filtering element (cartridge)s (2) (3) (4) that are communicated with in regular turn are set in a housing (1), cover with a loam cake (5) again, its middle shell outward appearance is similar to the pedestal of a heart, establish at interval with water inlet pipe (11) and drainpipe (12) in the bottom of a side, and drainpipe can be controlled turning handle (121) and control it and open and close action, and upper end two sides are then dug and established two locating holes (13).

First filtering element (cartridge) (2) is a cylinder, upper side is the opening shape, and come to be connected with pipeline (21) with water inlet pipe (11) in the upper end, to enter pipeline as the water source, and portion installs the high molecular filter pulp of one deck (22) in the mouth of pipe below of pipeline (21) within it, these filter pulp downside place central authorities are hollow mesentery (23), hollow mesentery periphery then is an outer ring water channel (24), outer ring water channel also has a pipeline (25) to connect in drainpipe (12), and the outlet of hollow mesentery central water channel is connected to second filtering element (cartridge) (3) porch, bottom side with a pipeline (26).Second filtering element (cartridge) (3) is oval cylindrical shell, fill in the cylindrical shell with filter materials such as layer by layer ion exchange resin and permeable membranes, and between different filter materials, establish one deck filter pulp and separated, and on cylindrical shell, place, downside gateway also is provided with filter pulp, to avoid filter material to run off and to sneak in the water.Filtering element (cartridge) (3) is come to be connected with the 3rd filtering element (cartridge) (4) by the pipeline (31) of upside exit with a two-way joint more in addition, filtering element (cartridge) (4) also is similarly oval cylindrical shell, its inside then fills with granular active carbon and medical stone filter material layer by layer, certainly also be provided with filter pulp in interlayer and place, upper and lower gateway, its exit, bottom side then connects establishes a pipeline (41), and this pipeline (41) is switched to the outlet pipe (51) of loam cake (5).And extend the elasticity fixture block (52) of outside protrusion in locating hole (13) corresponding section of loam cake bottom two sides and housing, and can allow loam cake be fastened on the upside opening part of housing, loam cake is being offered a hole (53) with the opening corresponding section of filtering element (cartridge) (2) upside, can hold a filter lid (27) and be inserted in the opening part that is screwed together in filtering element (cartridge) (2), and form a complete water filter.

After the water source is entered by the water inlet pipe (11) of housing, just following the inside that pipeline (21) flows into filtering element (cartridge) (2), and earlier by the filtration first of filter pulp (22) do, water by filter pulp just flows to outer ring water channel (24) and locates, because drainpipe (12) is a closed condition, make follow-up water source form pressure to the water source that riddles in the outer ring water channel, enter its inner lead and can see through hollow mesentery (23), enter filtering element (cartridge) (3) inside from pipeline (26) again, and by metal ion and calcium carbonate impurity in the ion exchange resin filter material filtered water in it, the permeable membrane filter material then is a nano-bacteria in the filtered water in addition, then water again by last side outlet by the road (31) by the last side inflow of filtering element (cartridge) (4), and do the filtration work of deodorizing and sterilization by its inner active carbon and medical stone, flow out for use via the pipeline (41) of filtering element (cartridge) (4) bottom outlet pipe (51) at last from loam cake (5).

The utility model is because the hollow mesentery of setting up in second filtering element (cartridge), pressure that needn't be very high just can allow the water infiltration and go into, drainpipe is provided with the control turning handle simultaneously, can make that the water that enters second filtering element (cartridge) is mandatory to be rested in the outer ring water channel, so can make most water carry out the permeation filtration action, and can reduce the waste of water resource effectively.Secondly after filter action is through one section reasonable time, but user's open row water pipe, allow the water of outer ring water channel follow the drainpipe discharge, then along with the action of its draining, be attached to the impurity on hollow mesentery surface, the water that will be flowed from top to bottom dashes the bottom of ring water channel outward, and discharges from drainpipe in the lump with the impurity that originally accumulated in this place, and this design can allow the hollow mesentery obtain longer service life.Simultaneously, because the utility model is to allow water through multiple times of filtration, the glassware for drinking water after feasible the filtration has and uses the same quality of reverse osmosis water filter, and low cost of manufacture, long service life.
