Abstract

The utility model provides a filtration device, wherein a filtration material (3) is a mixed forming body comprises a mixed forming body made from activated carbon and diatomite or activated carbon and cellulose. Thereby, the filtration material (3) can be used to filter water, in the meantime, water can backwash and filter the filtration material (3). The backwashing effect can be improved.

Description

Filter

Technical field

The utility model relates to not only can use the filter material filtered water, and filter that can water backwash filter material.

Background technology

In the past, the applicant developed and had proposed the filter of special formation.What be recorded in that Japan puts down into that patent application in 7 years announces No. 36910 communique (Chinese utility model is logined communique No. 185153) is exactly that.The device of described communique is the water purifier that directly links running water bolt pipe, it is characterized in that water purification cartridge and valve body integrated.Thereby, can rotate water purification cartridge and valve body integratedly, and can switch the flow path of water by valve body.Water purification cartridge is to have filled filter material.Its result not only can pass through the filter material filtered water, and can pass through water backwash filter material, thereby on water purifier market, its backwash function also is subjected to high evaluation so far.

Yet with regard to the device of described communique, it can pass through water backwash filter material, but problem is the effect of its backwash.To improve the backwash effect as far as possible, thus best backwash filter material fast and effeciently, and also its improvement is expected by people consumingly.

On the other hand, in the filter of filtered water, generally be that active carbon is used as filter material.As Japan put down into patent application in 4 years disclose No. 247232 record on the communique, filter material uses active carbon and diatomaceous mixed-forming body, also by known to the people.As Japan put down into patent application in 2002 disclose No. 355515 record on the communique, using active carbon and cellulosic mixed-forming body also by known to the people aspect the filter material.In this case, can improve filter effect by diatomite or cellulose.

The utility model is not only can be by filter material filtered water and can be by in the filter of water backwash filter material, considers that emphatically filter material makes.Its purpose is to improve the backwash effect.

The utility model content

According to the utility model as can be known, a kind of filter is provided, its water purification cartridge is filled with filter material, cover covers described water purification cartridge, water purification cartridge and valve body become one, it is characterized in that described filter material uses active carbon and diatomite are mixed the formed body of type, active carbon and cellulose are mixed the formed body of type or active carbon and diatomite and cellulose mixed the formed body of type.

In a preferred embodiment, filter is that direct binding water purifier by running water bolt pipe constitutes.

Description of drawings

Fig. 1 is the profile of expression embodiment of the present utility model.

Fig. 2 is the profile of the state that rotated of water purification cartridge in the presentation graphs 1.

Among the figure, 1-water purification cartridge, 2-valve body, 3-filter material, 6-running water bolt pipe.

The specific embodiment

Below, embodiment of the present utility model is described.

Fig. 1 represents filter of the present utility model.This device is that the water purifier by direct binding running water bolt pipe constitutes, and have with Japan and equal into the water purifier identical construction that No. 36910 communique (Chinese utility model is registered communique No. 185153) announced in patent application in 7 years, and integrated water purification cartridge 1 and valve body 2.Water purification cartridge 1 is to be used to fill filter material 3, and is box (cartridge) formula, and is contained in the cover 4.Valve body 2 is to be inserted in the case 5, and case 5 has outlet opening 7, and is installed on the running water bolt pipe 6.

Thereby, can pass through filter material 3 filtered water, and discharge from outlet opening 7.As shown in Figure 2, can be by rotating mask 4, water purification cartridge 1 and valve body 2 integratedly, thus switch the flow path of water by valve body 2, make water backwash filter material 3, the most described water is discharged from outlet opening 7.

And then, in this device, on filter material 3, used and put down into patent application in 4 years with Japan and disclose the same active carbon and diatomaceous mixed-forming body on No. 247232 communique.Thereby, by filter material 3 filtered water the time, improve filter effect by diatomite.

And then, in this device, can pass through water backwash filter material 3, but the use of filter material 3 active carbons and diatomaceous mixed-forming body is as previously mentioned.At this moment, improve the backwash effect by the mixed-forming physical efficiency.The designer has rediscovered this fact.And this is a starting point of the present utility model, basic feature.

Though it is not exclusively bright and clear to improve the reason of backwash effect, all know and contain particulate subsystem suspension or bacterium in the general water, and electronegative.On the other hand, if on filter material 3, use active carbon and diatomaceous mixed-forming body, then can take into account the negative electrical charge of itself being with.Thereby when filtered water, particulate subsystem class suspension or bacterium or filter material 3 are mutually exclusive under electro ultrafiltration, are difficult to adhere to.Its result just thinks, when backwash filter material 3, may be to have improved the backwash effect by the mixed-forming body.

Thereby, in this device, can improve the backwash effect by the mixed-forming body, and backwash filter material 3 fast and effeciently.And, can not damage filter effect therefrom.Improve filter effect as mentioned above by diatomite.

Also can disclose on No. 355515 communique, on filter material 3, can also use active carbon and cellulosic mixed-forming body as Japan's patent application in 2002.Also can on filter material 3, use active carbon, diatomite and cellulosic mixed-forming body.Even use active carbon and cellulosic mixed-forming body or active carbon, diatomite and cellulosic mixed-forming body, also can confirm to improve the fact of backwash effect by the mixed-forming body.Its reason is identical with diatomaceous mixed-forming body with active carbon.

Claims

1. filter, its water purification cartridge (1) is filled with filter material (3), and cover (4) covers described water purification cartridge (1), and water purification cartridge (1) and valve body (2) become one, it is characterized in that,

Described filter material (3) uses active carbon and diatomite is mixed the formed body of type, active carbon and cellulose are mixed the formed body of type or active carbon and diatomite and cellulose mixed the formed body of type.
