Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a purification filter used for purifying drinking water and non-potable water.

[Prior Art] Drinking water purification filters that have hitherto been on the market are actually used for dechlorination treatment. These purifying filters consist of a cartridge filled with activated carbon through which the water stream from the faucet is directed.

In addition, as another conventional example, there is a device equipped with a water diverter (d+verter) for optionally allowing the water flow to pass through the activated carbon or directly without passing through the activated carbon.

[Problems to be solved by the invention] In the conventional example described above, the entire amount of water flowing out from the faucet passes through the activated carbon, which causes a delay in water flow, and also has the disadvantage that the activated carbon depreciates faster, increasing the replacement rate. There is.

In the latter conventional example, the number of components usually increases and it is difficult to change the size of the purification filter according to the usage conditions, so the purification function is clearly insufficient for water with a high chlorine content. It is something.

Furthermore, the conventional method has the disadvantage that bacteria present in the water often contaminate the activated carbon, and the bacteria cannot be removed.

In addition, conventional purification filters are unable to remove air bubbles that get mixed into them due to long-term disuse or other causes, so when water is drawn, the purification filter is unable to remove the air bubbles. There is a problem that the original flow of water within the vessel is not achieved sufficiently.

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to providing a purifying 11-filter vessel that eliminates the above-mentioned drawbacks of the conventional example and can perform not only dechlorination treatment but also complete removal of bacteria.

In particular, an object of the present invention is to provide a purification filter that is equipped with two outlets, one for purified water and one for untreated water, so that water can selectively pass through the purification filter section, and the water flow can be taken from either of them. It's about doing.

Furthermore, the purpose of the present invention is to simplify the mechanism, allow selection of size according to usage conditions, complete purification,
Another object of the present invention is to provide a purifying filter that is easy to use.

Furthermore, it is an object of the present invention to provide a purifying filter that can be easily and quickly attached to any faucet due to its unique configuration and is sufficiently reliable and reliable in use.

Means for Solving Problem E] The purification filter of the present invention comprises a main body configured to be able to be connected to a water intake and to communicate the water receiving part with the purification filtration part, and a bacteria removal membrane. and a purification filtration section in which a layer of activated carbon is continuously arranged, and a water distribution means that has a purified water pipe connected to the untreated water pipe and the purification filtration section and is provided in the main body so that the position can be changed. When switched to the 1st position, the water receiving part is disconnected from the purification filtration part and connected to the untreated water pipe, and when switched to the 2nd position, the water receiving part is cut off from the untreated water pipe and the water receiving part is disconnected from the purification filtration part. It communicates with the purified water pipe through the section.

1 operation] When the water distribution means is in the first position, untreated water is directly obtained, and when it is in the second position, purified water is obtained. In addition, the standardized parts of the purification filtration section can be easily replaced.

The purification filter of this embodiment has a water receiving part (2) with a rotary joint (a) for connecting the water intake to the main body (1) or a male thread (3) for connecting with a similar part. It is equipped with

The water receiving part +2) is communicated with the purification filter part through the water channel (G), and the purification filter part consists of an end member (11) containing a bacteria removal membrane and 1 or 2 containing activated carbon. It consists of the above intermediate member (12) and is configured to be able to be assembled with each other.

Specifically, the purification filtration section is provided with an axial pipe (15), which extends through the intermediate member and the end member, and filters water entering the water receiving section (2) for purification. It communicates with a waterway (g) for guiding people to the area.

The axial tube (15) has a perforated gap at its end! ! (16) is provided, and this perforation interval! (16) serves to appropriately reduce the water pressure and allow the water flow to pass slowly through the purification filtration section.

This shaft tube (15) is made up of independent individual parts, which are closely attached to each other and extend to the end member (11).

The end member (11) connects the axial tube (15) and has an axially perforated front flange (21) and, together with the front flange (21), a pleated bacteria removal III (23). It houses a rear flange (22) for holding. The bacteria removal membrane (23) has a substantially cylindrical shape and functions to prevent passage of bacteria. Bacteria removal 1! (23) has been shown to block the passage of bacteria larger than 0.45 microns. The bacteria removal membrane (23) has a first layer on its outer surface.
A contalnment net is placed over the membrane to protect the bacteria removal membrane from damage caused by abnormal pressure increase.

Inside the bacteria removal membrane (23) is a fine mesh filter covered with a cloth layer (2G).
ter) (25) is built-in. The fine mesh filter (25) functions as an important purification element and acts to reduce water pressure.

In addition, bacteria removal l1l is also applied to the outer periphery of this cloth layer (26).
(23) as well as for the second protection net (27).
) to protect it from damage caused by sudden pressure fluctuations.

The lζ water flowing from the axial pipe (15) passes through the bacteria removal membrane (2).
3) and fills the end member <11). Furthermore, the water flow passes through the perforated plate (30) and activated carbon (31).
) flows into the intermediate member (12) filled with.

The intermediate member (12) filled with activated carbon is closed at its end with a filter plate (32) such as felt. Filter plate (
32) has the function of further lowering the water pressure and preventing the activated carbon from flowing out from the intermediate member (12).

The filter plate (32) is held in a pressed state against an arid (33) located at a position that partitions the purification filter section. The grid (33) is employed to define a water outlet chamber (35), into which the purified water that has passed through the purifying filter is dyed.

As shown in Figures 1 to 8, the water receiving part (2) is a water distributor (40).
It also communicates with the purification filtration section.

The water distributor (40) is rotatably attached to the main body (1) and includes an untreated water pipe (41) and a purified water pipe (42).

More specifically, the water distributor (40) has an untreated water inlet (43) on the surface facing the main body, and an untreated water inlet (44) bored in the water receiving part (2). They are configured so that they communicate with each other, and are further equipped with a ring seal to prevent water leakage.

The water distributor (40) also has a purified water pipe (42),
This is connected to the purified water inlet (45) opened on the opposite side, and the water outlet chamber (35) on the main body (1) side.
It is designed to face and communicate with a water pipe to be purified (46) connected to the water pipe (46).

Untreated water! ! (41) and the purified water pipe (42) each have an untreated water inlet (43) and a purified water inlet (45) at opposite positions in the diametrical direction of the water distributor (40).

When switching to the first position (the eighth position), the water distributor (40)
(see figure), the untreated water ring port communicates with the untreated water inlet (43), so water entering from the water receiving part (2) passes through the purification filtration part as if it were a separate component. Instead, it flows directly into the untreated water pipe (41) and is distributed.

When purified water is desired, the water distributor (40) is rotated to the second position as shown in FIG. As a result, the untreated water ring opening (44) is closed, and the water entering from the water receiving part [2] flows toward the purifying filtration part, passes through the end member (11) and the intermediate member (12), and is purified. The Rukoto.

The purified water enters the purified water inlet (45) from the water pipe to be purified (46) and is distributed to the outside.

The switching position of the water distributor (40) with respect to the main body (1), that is, the selection of whether water is to be passed directly from the water receiving part +21 or when the purified water pipe (42) is passed through the water pipe to be purified (46) is ensured. Therefore, there are rotation stopping members (detents) consisting of small protrusions (peas) at two locations in the diametrical direction of the main body (1).
) (50) is provided. When this is engaged with the rotation stopping member (51) on the water distributor side, the two switching positions can be accurately positioned.

The operation of collecting purified water using the purifying filter of the present invention is extremely simple. For example, if the user does not need purified water, all he has to do is turn the water distributor (40) so that the untreated water pipe (41) and the untreated water spout (44) face each other.

This allows the water to flow out without passing through the purification filter.

When the user wants to obtain purified water, he rotates the water pipe (40), closes the untreated water ring opening (44), and releases the purified water pipe (42).
is switched to connect to the water pipe to be purified (46) from the water outlet chamber (35).

In that case, the water entering from the water receiving part (2) passes through the shaft pipe (15) and enters the end member (11), where it is filtered by a fine mesh filter (25), a fabric layer (26>, and a second protection net (21). ), and further passes through a bacteria removal membrane (23).The bacteria removal membrane removes all bacteria and prevents contamination of the activated carbon (31).

The water that has passed through the bacteria removal membrane (23) slowly passes through the activated carbon layer, and at this time, the water comes into contact with the activated carbon, thereby fulfilling its original role of purifying the water. As mentioned above, in the case of water with a high content of chlorine, a plurality of intermediate members may be provided.

If standardized end members and intermediate members are available, worn out parts can be replaced simply by replacing them, and in most cases replacement of intermediate members with activated carbon is preferred over end members with built-in bacteria removal membranes. would be more frequent.

Water exits the activated carbon bed (31), enters the water outlet chamber (35), and then passes through the purified water pipe (46) to the purified water pipe (42).
), the water is distributed as purified water.

If air bubbles are generated or mixed in the purifying filter section, the original flow of water will be obstructed as described above. Therefore, one end of the air vent pipe (60) is opened into the waterway and installed.
The other end is led outside and a small air vent valve (61) is placed at the outlet.
has been established.

If air bubbles appear, connect the water intake to the water receiving part, and then press the air release valve (61) until water drops drop. Air bubbles are thereby removed from the inside, and the purifying filter can resume its effectiveness as originally intended.

FIGS. 10 to 15 show other embodiments having means for changing the water flow.

In these drawings, the same reference numerals are used for the same parts as in the previous embodiment.

In these drawings, in addition to the water receiving part (2), the main body (1
) is provided with a water distribution chamber (71) separated from the water receiving section by a partition wall (72).

Separation! ! A through hole (73) is bored in the (72), and a closing means (74) is interposed therein. The closing means (74) has a valve head (76) acting as a closing member for the passage hole (73) and a stem (15) inserted into the passage hole (73).
It is equipped with

The stem (75) is axially displaceable, and in the first position, the through hole (73) is closed, and in the second position, the water flow between the water receiving part (21) and the water distribution chamber (71) is closed. enable.

The stem (75) is operated by a small shaft (77). The shaft (71) is supported in the diametrical direction above the water distribution chamber (71) and protrudes from the main body (1) in a liquid-tight manner, and the protruding portion is provided with a lever for rotating the shaft (77). (78) is provided.

The shaft (77) has a tapered biased portion (79) at an intermediate position thereof, and the biased portion (79)
is substantially biased relative to the ring of the shaft (17) and engages an aperture (80) in the stem (75). Further, the opening (80) is provided with a set screw (81) that comes into contact with the offset portion (79). This allows the shaft (
When the stem (77) rotates, the stem (75) slides in the axial direction due to the biased portion (19) (L; (81)), thereby opening the through hole (13). Open and close.

The function of the purification filter section is substantially the same as in the first embodiment.

When the user wishes to fill up the untreated water, he or she rotates the lever (78) to open the closing means and allow free flow through the through hole (73).

In that case, the water does not enter the purifying filter part but directly flows into the water distribution chamber (71) from the water receiving part (2) because the purifying filter part has a large resistance to water pressure.

When the user wants to get purified water, he operates the lever (78) and closes the through hole (73) with the valve head (16). As a result, water is forced to flow toward the purifying filter section and is purified. In other words, the water flows into the water outlet chamber (35).
From the water distribution chamber (11) through the water pipe to be purified (4G)
flows out.

Furthermore, a small protrusion (82) is attached to the main body (1) to limit the movement of the lever (78) in order to accurately determine the rotational position of the lever (78).

As shown in FIG. 16, a purifying filter operated by a hydrogen feed element may be provided. In that case, the purification filter is not provided with a rotatable water distributor. This is because most of the water taken out above is purified. A pump element (70) may be provided in the conduit to provide water supply power and help overcome pressure losses and drops occurring within the body.

[Effect of the invention] The purifying filter of the present invention provides the following effects.

Since bacteria in the water can be removed, purified water with high purity can be obtained, and at the same time, the activated carbon is not contaminated by bacteria, so the life of the activated carbon can be extended.

Furthermore, since untreated water can be directly filtered, the life of the purifying filtration section can be extended, and it can be used in accordance with the purpose of use.

Furthermore, by using standardized members, it is possible to use different capacities depending on the conditions of use, and to easily replace the members.

Furthermore, if an exhaust valve is provided, it is possible to remove air bubbles and prevent the function of the purifying filtration section from deteriorating.
