Description

Activated Carbon Filter Housing for Water Purification

The present invention relates to an activated carbon filter housing for water purification, which is used to filter foreign substances contained in tap water. More specifically, the filter housing can be reused by replacing only activated carbon when the service life of the activated carbon embedded in the housing has passed. The present invention relates to an activated carbon filter housing for water purification.

In general, an activated carbon filter for filtering impurities contained in tap water is used in a water purifier to purify tap water. The activated carbon filter is embedded in a housing in which the remaining portion except for tap water inlet and outlet is sealed.

Since the housing must be formed with a space for inserting activated carbon therein, the housing is divided into a main body and a cap so that the activated carbon or activated carbon filter is inserted into the space and the main body and the cap are sealed to each other to remove impurities from the tap water. Even if water pressure (approximately 5 to 10 kg / cm ² ) is applied, no water leakage occurs at these joints.

1 is a perspective view showing an embodiment of a conventional water filter, and FIG. 2 is a front view showing a part of FIG. 1 in a cross-sectional view, in which a filter housing is divided into a main body 1 and a cap 2, and the main body and the cap are disposed on the main body and the cap. The formed inlet 3 and outlet 4 are fitted with a fitting 5 for connecting a hose (not shown) to the housing, and the connection surface of the fitting is connected to the outer circumferential surface of the hose to maintain airtightness. (6) is fitted.

One embodiment configured as described above, after filling the activated carbon 7 into the cap 2 and the main body 1 formed separately, the cap 2 is coupled to the main body 1 and leaks are generated through their coupling portions. Not to be fused.

Accordingly, even if water pressure is applied in the housing to purify the tap water, no leakage occurs through the connection portion between the main body 1 and the cap 2.

However, this conventional filter housing has the following problems.

First, when the main body 1 and the cap 2 are fused and the activated carbon filter is used for a certain period of time, and the water purification function is reduced, only the activated carbon filter cannot be replaced. Therefore, the activated carbon filter housing must be completely replaced. .

Second, in order to recover the discarded activated carbon filter housing, it is possible to remove the activated carbon in the space by separating the main body and the cap, but considering the labor cost, it is unrealistic to remove and recycle the activated carbon. The situation is to embed the activated carbon filter housing.

Accordingly, in terms of cost, it causes a large loss (about 1000 won × 40,000 = 40,000,000 won per piece) as well as the problem of contaminating the soil.

Third, the plurality of filters (activated carbon, ceramics, etc.) because the directions of the fittings 5 for connecting the hoses, that is, the inlets 3 and the outlets 4, are shipped in a state determined at the time of production of the filter housing, and thus the position is impossible to change. In the case of installing in parallel, the hose forming the flow path is bent, thereby reducing the discharge amount of the purified tap water, and in severe cases there is a closed end that the bent portion of the hose is torn.

In order to solve the third problem described above, a new type of filter housing illustrated in FIGS. 3 and 4 has been developed.

Figure 3 is a perspective view showing another embodiment of a conventional water filter and Figure 4 is a side view of Figure 3, the housing is divided into the main body 1 and the cap (2) and the coupling portion thereof is fusion-fixed one embodiment Is the same as

The difference from the above-described embodiment is to have the orientation of the fitting 5 connected to the inlet 3 and the outlet 4 for connecting the hose.

That is, a separate thin tube 8 is integrally formed in the main body 1 and the cap 2 so as to couple the elbow-shaped fitting 5 to the tube.

As a result, when the plurality of filter housings are installed in parallel as shown in Fig. 4, the hoses forming the flow paths by rotating the fittings 5 along the direction of the flow paths are prevented from bending or bending.

However, such a structure can also solve the third problem of the embodiment, but the first and second problems can not be overcome because of the fusion of the coupling portion of the body (1) and the cap (2).

In addition, the thin tube 8 which serves as the inlet and outlet of the main body 1 and the cap 2 and serves as a coupling part of the fitting 5 is integrally formed so that the thin tube is broken by an external impact. You will have a fatal flaw.

The present invention has been made to solve such a problem in the prior art, the connection of the hose to form a flow path at the same time to prevent the phenomenon that the water leakage occurs in the coupling portion of them without fusion welding the coupling portion of the main body and the cap Its purpose is to be able to change the direction as needed.

According to an aspect of the present invention for achieving the above object, in that the activated carbon filter is embedded in the space portion of the housing formed by dividing the main body and the cap, the O-ring insertion groove is provided and separated from the cap when the hydraulic pressure is applied to the housing. The pressing member for pushing the O-ring in the insertion groove toward the main body is inserted, and the inner circumferential surface of the cap is formed with a female thread, and the surface connected to the O-ring inserted in the O-ring inserting groove is an inclined upward slope toward the outside, and the female thread formed in the cap on the outer circumference And a fitting having a male thread to which the male thread is screwed, a hook that is rotatably fitted to the inlet and the outlet formed in the main body and the cap, and an O-ring that is fitted to the coupling portion of the fitting to maintain airtightness. An activated carbon filter housing for water purification is provided.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 5 to 7 as an embodiment.

5 is an exploded perspective view illustrating the present invention, and FIG. 6 is a longitudinal cross-sectional view of the coupled state of FIG. 5, and FIG. 7 is an enlarged view of a portion of “; A” of FIG. 6. The description is omitted and the same reference numerals will be given.

The present invention is provided with an O-ring inserting groove (9) in the cap (2) formed in the main body 1 and the cap is separated from the cap when the hydraulic pressure is applied to the housing inside the O-ring (10) in the O-ring insertion groove The pressing member 11 which pushes to 1) side is inserted, and the internal thread 12 of the cap 2 is formed.

The main body 1 to which the cap 2 is coupled is an inclined surface 13 which is inclined upward as the outer surface is connected to the O-ring 10 inserted into the O-ring inserting groove 9, and an external thread The male screw 14 is screwed together.

And one side of the fitting (5) coupled to the inlet (3) and the outlet (4) formed in the main body (1) and the cap (2) is formed with a hook (15) rotatably fitted to the inlet and outlet The engagement portion of the fitting is fitted with an O-ring 16 for maintaining airtightness.

Referring to the operation of the present invention configured as described above are as follows.

First, the cap 2 is obtained by performing an injection molding operation in a state in which the pressing member 11 is inserted therein.

After the cap 2 is obtained in this manner, the fitting 5 is located in the state in which the O-ring 16 is positioned in the boss 17 of the water inlet 3 formed in the main body 1 and the water outlet 4 formed in the cap 2. When the hook 15 is formed on one side of the inlet and outlet, the inner diameter of the inlet and outlet is smaller than the diameter of the hook, so that the hook is retracted inward and then returned to the initial state after passing through the inlet and outlet. 5) is in a rotatable state without being separated from the main body 1 and the cap 2.

As described above, after the fittings 5 are coupled to the main body 1 and the cap 2, the o-rings 16 in the bosses 17 are pressed by the fittings to maintain a compressed state. This will prevent leakage.

Thereafter, a well-known activated carbon filter 7 is inserted into the space portion of the main body 1, and then the cap 2 is screwed onto the main body 1 by using the female screw 12 and the male screw 14, respectively. The assembly work of the housing is completed.

After the housing is completed as described above, the filter housing can be installed by connecting the hose while varying the position of the fitting 5 rotatably coupled to the main body 1 and the cap 2 according to the direction of the flow path.

If water pressure is not applied to the filter housing while the filter housing is installed in the above-described operation, the O-ring 10 in the oil insertion groove 9 maintains only the state pressed by the inclined surface 13 formed on the main body 1. .

In this state, when the hydraulic pressure is applied to the filter housing, the O-ring 10 in the O-ring inserting groove 9 is pushed outward while being deformed by the hydraulic pressure as shown in FIG. 7 by the applied hydraulic pressure. The upwardly inclined inclined surface 13 is pushed out of the O-ring 10 is tightly sandwiched between them to maintain the airtight.

Since this phenomenon is proportional to the hydraulic pressure applied, it is possible to always expect a constant sealing effect even if a large hydraulic pressure is applied.

In addition, when the hydraulic pressure is applied to the housing, the resin filter housing is expanded, so that a minute gap is generated between the cap 2 and the pressing member 11 that are in close contact with each other. Since the O-ring 10 is pushed toward the side, a more certain sealing effect can be expected.

On the other hand, if the filter water of the activated carbon is deteriorated due to the long-term use of the filter housing, and the supply of tap water is stopped so that water pressure is not applied to the housing for replacement, the cap 2 can be easily separated from the main body 1 without using a separate tool. You can do it.

That is, when the hydraulic pressure is applied, the O-ring 10, which was kept in airtight while being deformed while being pushed outward along the inclined surface 13 by the hydraulic pressure, is reduced to the initial state, so that the cap 2 in the main body 1 with a small force. Can be separated.

Accordingly, by removing the contaminated activated carbon filter 7 from the main body 1, inserting a new activated carbon filter, and locking the cap 2 as described above, it is possible to filter out foreign substances in the tap water. You will get.

As described above, the present invention has the following advantages over the conventional filter housing.

First, when the activated carbon filter 7 is inserted into the space portion of the main body 1 and the hydraulic pressure is applied to the housing while the cap 2 is screwed, the O-ring 10 follows the inclined surface 13 of the main body 1 by the hydraulic pressure. As it is deformed to the outside, it is tightly sandwiched between these gaps to maintain airtightness, and when water pressure is removed for replacement of activated carbon, the O-ring is reduced to the initial state, so that the cap 2 can be opened with a small force, thus enabling the replacement of activated carbon. As a result, it is possible to reduce the cost of replacing the activated carbon.

Second, it is possible to replace the activated carbon (7) embedded in the space of the housing to enable the repeated use of the housing to prevent contamination of the soil due to the disposal of the housing in advance.

Third, the fitting 5 for connecting the hose is rotatably coupled to the main body 1 and the cap 2 so that the position can be changed freely, so that a plurality of filters (activated carbon, ceramics, etc.) are connected in parallel. Even if you want to install or change the flow path to prevent the hose from bending in advance.
