Figure 3b is a view showing a state just before fastening the filter assembly of Figure 2 according to the present invention to the adapter of Figure 1a according to the present invention, Figure 3c is a view according to the present invention to the adapter of Figure 1a according to the present invention 2 is a view showing a state in which the filter assembly is fully fastened.

The fastening process of the filter assembly 200 according to these drawings is as follows.

First, when the filter assembly 200 is pushed up toward the center through hole at the bottom of the adapter 100, the collar flange 215 formed at the upper inlet of the outer housing 210 of the filter assembly is semicircle of the slide plate 50. It moves upward in contact with the inclined portions 51a 'and 51b' of the arc portions 51a and 51b.

As a result, both slide plates 50A and 50B are moved away from each other, and at the same time, the projections 40a fitted in the inclined long holes 50a and 50b are slightly advanced. At this time, the position of the projection 40a inserted into the inclined long holes 50a and 50b of the slide plate is located at the center of the long hole as shown in FIG. 3B.

At this time, the sealing is already made in all parts between the adapter 100 and the filter assembly 200. In more detail, the state of FIG. 3B is just before the filter assembly 200 is fastened to the adapter 100. Under the circumstances, the push rod 220d installed at the inner center of the separation wall 220a formed at the front end of the inflow and outflow guide 220 pushes the lower end of the valve plunger 20c installed in the flow passage 20a of the check valve. Just before posting. Therefore, since the O-ring 20e of the valve plunger is still in close contact with the inclined seat surface 20f formed on the inner surface of the valve body, the flow path 20b of the raw water is closed. At the same time, the raw water outflow prevention O-ring 20g installed at the bottom of the flow passage 20a is connected to the inner surface of the dividing wall 220a installed to prevent mixing of raw water and purified water inside the filter assembly 200 to maintain a sealing state. One or more O-rings 230 for preventing purified water leakage installed on the outer diameter surface of the cylindrical flow passage at the tip of the filter assembly are connected to the inner surface of the central through hole of the adapter 100 to maintain the sealing state. The flow passage and the flow passage of purified water are separated so as not to mix with each other. In addition, the sealing is made so that the purified water does not flow out of the space other than the flow path formed in the filter assembly and the adapter.

When the collar flange 215 of the filter assembly passes over the inclined portions 51a 'and 51b' of the slide plates 50A and 50B, the slide plate 50A under the opposite direction by the spring S is received. 50B moves in a direction facing each other to constrain the collar flange 215, thereby eventually tightening the filter assembly 200.

At this time, the separation button means 40 is the projection 40a is inserted into the inclined long holes (50a, 50b) formed in the slide plate (50A, 50B) is slid toward the front side so that the release button is protruding toward the front side. At the same time, the position of the projection 40a inserted into the inclined long holes 50a and 50b of the slide plate is slightly spaced apart from the lower end of the inclined long holes 50a and 50b as shown in FIG. 3C.

During fastening, the push rod 220d of the filter assembly pushes upward the valve plunger 20c of the check valve 20 in the adapter 100, so that the O-ring of the valve plunger that is in close contact with the inclined seat surface 20f. As 20e is spaced apart from the inclined seat surface 20f, the raw water flow path 20b in the closed state is opened. Since the check valve is in communication with the inlet 10in of the adapter body 10, when the check valve is opened by the fastening process as described above, the raw water introduced from the inlet 10in is the raw water inlet 10c, the check valve body. It flows into the dividing wall 220a of the inflow and outflow guides 220 through the raw water flow path 20b of the central flow passage 20a.

The inflow water supplied into the filter assembly is purified water by the separation wall 220a installed at the tip of the inflow guide 220 disposed between the filter material and the inlet, and the O-ring 20g for preventing the outflow of raw water as shown in FIG. 3C. And mixing is prevented, and flows between the inner surface of the outer housing 210 and the outer surface of the filter material 240 again while passing through the raw water flow path switching passage (220b) and then filtered while passing through the filter material, It moves upward and flows again between the outer surface of the purified water outlet passage 220c formed in the influent guide 220, the outer diameter surface of the separation wall 220a and the flow passage 20a of the check valve and the inner diameter surface of the neck of the filter assembly. It is discharged through the purified water outlet 10e and the purified water outlet 10out of the adapter via the flow space 10d.

On the other hand, when the fastening is completed, in order to prevent the accidental separation does not occur, by mounting the safety pin in the safety pin mounting hole 45 of the separation button means 40 to make the release button means in the stopped state.

FIG. 3D shows a method for detaching the filter assembly of FIG. 2 according to the present invention from the adapter of FIG. 1A according to the present invention in the fastened state of FIG. 3C.

When it is necessary to replace the filter assembly 200 which is fastened to the adapter 100, the one-touch separation is performed by simply removing the safety pin from the release button means 40 and then pressing the button means.

When the release button means 40 is pushed, the release button means is advanced so that the protrusion 40a of the separation bar is also advanced, and the protrusion is fitted into the inclined holes 50a and 50b of the slide plates 50A and 50B. Forward movement of the projections causes the slide plates to move in opposite directions. Accordingly, the slide plate that has restrained the collar flange 215 of the filter assembly is moved left and right, and the restrained state is released to separate the filter assembly. At this time, since the actuation of the valve plunger 20c is released when the pressing force applied from the push rod 220d is released and only the elasticity of the valve spring 20d is received, the valve plunger is moved downward and the O-ring 20e of the valve plunger is moved. It comes in close contact with the internal inclined seat surface 20f of the valve body to block the flow of raw water.

According to another feature of the present invention, the present invention provides a multi adapter for fastening the plurality of filter assemblies (200a, 200b, 200c, 200d, 200e) described above. An example of such a multi adapter is shown in FIG.

In general, in the products equipped with a plurality of filters such as a water purifier or an ionizer, each filter has a different role and service life. This is not a case of replacing all the filters at the time of filter replacement, but only at the end of life. Regardless of which filter is replaced, it is necessary to cut off the raw water.

However, since the multi-adapter according to the present invention has a check valve 20 built in itself, no need of separate raw water cutoff is required for any filter replacement, and the replacement operation is simply completed by inserting a new filter after pressing the release button. There is a characteristic.

The outer peripheral surface of the plug-type connecting member 150 and the inner peripheral surface of the inlet and outlet are preferably sealed with an O-ring, and for the convenience of filter replacement, each single adapter constituting the multi-adapter is a plugged connection. Since the member is configured to be rotatable about the axis, the lower cover plate 10b of the bottom of the adapter rotates to the front of the person performing the filter change, so that the filter change work can be more conveniently performed.

The present invention also relates to a water purification system comprising any one or more of the one-touch removable single and multi adapters described above and a filter assembly detachable therefrom. In other words, the one-touch removable single and multi-adapters described above and the filter assembly detachable therefrom may exist as part of various types of water purification systems, such as bidets, water ionizers, and thus cover all such water purification systems.

According to the above, the present invention provides a one-touch removable filter assembly and an adapter capable of fastening and detaching a filter assembly used for a bidet, a refrigerator, and the like, and an adapter for attaching and detaching the filter assembly to an application device in a one-touch manner.
