Description

A kind of direct drinking combination purification filter core

Technical field

The utility model relates to a kind of filter cores, and in particular to a kind of direct drinking combination purification filter core.

Background technique

The reverse osmosis membrane tube filter core or use diatomite ceramic tube that existing tap water water purifier filter core substantially uses Filter core cooperates basic configuration of the activated carbon adsorption filter core as water purifier.The shortcomings that reverse osmosis membrane is that filter core will be replaced in time, filter Water out is substantially pure water, and in addition the maintenance requirement of reverse osmosis membrane filter element is relatively high, often has what user do not know When replacement filter core and lead to the unqualified phenomenon of water quality；The shortcomings that diatomite ceramic tube is own has, hydraulic pressure not It is easily damaged when stablizing or during transporting, installing and using, and he uses adhesive glue used in plastic closures often To people with the presence of unfavorable factor, its drainage process is to first pass through ceramic tube filtering, and then plus activated carbon adsorption just directly goes out Water is drunk.Above two water purifier filter core is lacked in outlet and is protected together, be may cause some unsound particulate matters and is mixed into drink With in water.And two kinds of filter cores were generally just needed replacing at 3 to 6 months, increased the working service cost of user.

Utility model content

Purpose of the utility model is to solve the above problems and provide a kind of direct drinking combination purification filter cores.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A kind of direct drinking combination purification filter core includes upper cover, filter core outer box, it is characterised in that: in the filter core outer box from Top to bottm is successively arranged Diatomite ceramic filter core, active carbon filter core, spare filter box, Chinese medicinal stone filtering element, lower diatomite ceramic filtering Core, the lower section of the lower Diatomite ceramic filter core are located at filter core outer box bottom equipped with water outlet, the upper Diatomite ceramic filter core Thread is equipped in the filter core outer box of upside, the upper cover is mounted in filter core outer box by thread, on the upper lid Equipped with water inlet.

Further, the filter core outer box inner wall respectively with upper Diatomite ceramic filter core, active carbon filter core, spare filter box, Ring type seal is equipped between Chinese medicinal stone filtering element, lower Diatomite ceramic filter core.

Further, the outer upper ends of the filter core outer box are equipped with seal groove, are equipped with O-ring seal in the seal groove.

Further, the sealing ring is made of food grade silicone.

The utility model is the utility model has the advantages that existing diatomite ceramic screen pipe is changed to ceramic filtering by the utility model purifying filter element Piece so that the relatively reliable safety of tap water filter, and user after a period of use, it may be convenient to upper layer quilt is removed in polishing The impurity of filtering, makes porcelain filter disc activate filtering function again, and such a ceramics filter disc can be used 1 year or so, greatly drop Low customer using cost.It is combined additionally by by the upper, middle and lower of diatomite ceramics filter disc, active carbon filter disc and Chinese medicinal stone filtering element, on Layer filtering accuracy is that 0.1 micrometer ceramics filter disc filters out in tap water due to the issuable bacterium of secondary water-supply, virus and micro- life The metal pollutants such as the iron rust in object and pipeline；Intermediate active charcoal filter disc filter out chlorine residue in tap water, disinfection by-products, The organic pollutants such as peculiar smell；Chinese medicinal stone filtering element is added to the mineral matter element beneficial to human body, lower layer's ceramics filter disc to direct drinking The unstable particle due to omitting in active carbon filter disc and Chinese medicinal stone filtering element is filtered out, the end-filtration protection for playing direct drinking is made With keeping the production of direct drinking simpler reliable.It is also provided with a spare filter box simultaneously, can be required according to user convenient It is beneficial and remove the function filter materials of the pollutants such as removing heavy metals to add some pairs of human bodies, reaches a filter core and realizes tap water purifying For the overall process of direct drinking.

Detailed description of the invention

Fig. 1 is the schematic perspective view of the utility model；

In figure: 1- upper cover, 2- filter core outer box, the upper Diatomite ceramic filter core of 3-, 4- active carbon filter core, the spare filter box of 5-, 6- Diatomite ceramic filter core, 8- lower outlet, 9- filter core ring seal circle, 10-O type sealing ring, 11- filter under Chinese medicinal stone filtering element, 7- The upper water inlet of box cover thread, 12-.

Specific embodiment

Specific embodiment of the present utility model is further described with reference to the accompanying drawing.

As shown in Figure 1, a kind of direct drinking combination purification filter core of the utility model, includes upper cover 1, filter core outer box 2, spy Sign is: being successively arranged Diatomite ceramic filter core 3, active carbon filter core 4, spare filter box in the filter core outer box 2 from top to bottom 5, Chinese medicinal stone filtering element 6, lower Diatomite ceramic filter core 7 will be wrapped up around above-mentioned filter core with loop-type product grade silica gel sealing ring 9 Afterwards, it is embedded in filter core outer box 2, keeps each filter core outer rim and 2 inner wall of filter core outer box water-tight, the lower Diatomite ceramic filter core 7 Lower section is located at 2 bottom of filter core outer box equipped with water outlet 8, the interior company of being equipped with of filter core outer box 2 of upper 3 upside of Diatomite ceramic filter core Screw thread 12 is connect, the upper cover 1 is mounted in filter core outer box 2 by thread 12, and the upper cover 2 is equipped with water inlet 13.Institute The outer upper ends for stating filter core outer box 2 are equipped with seal groove 10, are equipped with O-ring seal made of food grade silicone in the seal groove 10 11, realize the sealing when filter core outer box 2 are packed into water purifier filter tank.

When utility model works, the filter core outer box 2 for installing filter core are mounted in water purifier filter core pond, tap water passes through upper Water inlet 8 on lid 1 enters in filter core outer box 2, under the action of tap water gravity or pipeline pressure, leaks into water outlet step by step 12, export qualified direct drinking.
