The cover 60 has a cylindrical rim 64 extending from the opposite face of the filter housing 50, as shown in Figs. 4-6. These rims 64 are gripped and pressed (pulled) by the user's fingers F1 and F2 as shown in Fig. In particular, the rim 64 is held at the ends of the fingers F1 and F2 as shown in Fig.

6, the rim 64 is formed at an outer diameter corresponding to the outer diameter of the end of the filter housing 50, and is in close contact with the end of the filter housing 50 to isolate the end of the filter housing 50 from the outside. State. When the boss 51 is formed in the filter housing 50 as shown in FIG. 6, the rim 64 is attached to the end of the boss 51 as shown in FIG. . This will be described later.

The cover 60 is formed such that its outer diameter is larger than the outer diameter of the aforementioned rim 64 as shown in Figs. The cover 60 has a rim 62 (outer peripheral surface) projecting outwardly of the rim 64 like a flange. The cover 60 is engaged with fingers F1 and F2 on the protruded rim 62 as shown in Fig. That is, the cover 60 acts as a hook. Accordingly, since the user can easily grasp the cover 60, the user can smoothly transmit the gripping force to the cover 60 to move the cover 60 easily.

6, the cover 60 has a rim 64 in such a state that the end of the rim 64 can be in close contact with the end of the above-described boss 51 formed in a protruded state at the end of the filter housing 50, It is preferable that the diameter and length are formed. 6, the rim 64 is brought into contact with the end of the boss 51, so that the inside of the boss 51 is isolated from the outside, and the above-described protrusion of the filter housing 50 The jaw 53 is completely hidden. Thus, the filter housing 50 provides a simple yet foolish appearance as the protruding jaws 53 are concealed.

4 and 7, the filter housing 50 may be coupled to the communication tube 55 by a coupler including a conventional coupler 70 or a conventional cap (not shown).

4 and 7, the coupler 70 is inserted into one side of the communication tube 55 of the filter housing 50 passing through the cover 60 as shown in Fig. Respectively. The coupler (70) is connected to the other side of the connector (not shown) through which water flows. Accordingly, the coupler 70 integrally connects the communication tube 55 and the unshown connection pipe. That is, the coupler 70 is a member that connects two pipes together.

And, the above-mentioned ordinary cap not shown is a cap which is coupled to the communication tube 55 of the filter housing 50. The cap is coupled to the end of the communication tube (55) to prevent dust or foreign matter from entering the communication tube (55). Such a cap is a typical member that can be easily understood by a person skilled in the art, and a detailed description thereof will be omitted.

As shown in Fig. 7, the coupler 70 is provided with a thin metal plate 78 on its inner side which is fixed to the outer circumferential surface of the communication tube 55 inserted into one side with its inner side wedged. 7, the metal plate 78 may be fixed to the bush 74 by an insert. Alternatively, as shown in FIG. 9, the metal plate 78 may be inserted into the sleeve 76, which will be described later, .

As shown in FIGS. 7 and 9, the coupler 70 is provided at its one side with a tubular sleeve 76 which is slidably installed along the longitudinal direction of the communication tube 55 inserted into one side. 7 and 9, almost all of the sleeve 76 is inserted into one side of the coupler 70, and a part of the sleeve 76 is protruded to the outside of the coupler 70. 7 and 9, the outer circumferential surface of the upper end of the sleeve 76 protrudes outwardly, and a hook HK is formed at the upper end. 2). That is, the cylindrical sleeve 76 is formed in a concavo-convex shape due to the cut-out portion. As shown in FIG. 2, the sleeve 76 has a cut-out portion formed at regular intervals along the circumferential direction. Therefore, the diameter of the sleeve 76 can be expanded or contracted as required.

The coupler 70 is provided with an expanding portion 72 at one end as shown in FIG. 7 so that the metal plate 78 and the sleeve 76 are easily inserted. That is, the ends of the coupler 70 are expanded. As shown in FIG. 7, the coupler 70 may be equipped with an O-ring R in the inside of the expanded portion 72, and the inner circumferential surface thereof may be sealed. 7, the coupler 70 is provided with a bushing 74 which is fixedly held on the inner circumferential surface of the bending portion 72 and is fixed in a locked state. As shown in the figure, the bushing 74 is provided with a metal plate 78 may be fixed with an insert.

The other side of the coupler 70 may be configured in the same manner as the one described above. That is, the coupler 70 may be provided with the above-described expanded portion 72, the metal plate 78, the sleeve 76, and the O-ring R on the other side, and the bush 74 may be additionally provided . When the coupling pipe (not shown) is fitted to the other side of the coupler 70, the metal plate 78 is fixed to the coupling pipe and is fixed to the wedge, and the metal plate 78 is unlocked by the cover 60 have.

9, the coupler 70 may be formed only of the sleeve 76 without the bush 74 described above, and in this case, the expansion portion 72 into which the sleeve 76 is inserted, as shown in the figure, An inclined surface 72a is formed inside the doorway of the door, and is formed as a section of upper light-tight narrowing.

The sleeve 76 is inserted into the tube portion 72 with the upper end formed with the hook HK pinched. The sleeve (76) is fixed to the inside of the tube portion (72) as the clipped upper end is circularly restored inside the tube portion (72). When the communication tube 55 moves downward in the figure due to a hydraulic pressure reaction due to the hydraulic pressure applied to the communication tube 55, the sleeve HK descends and the lower portion of the narrowed tube portion 72 Lt; / RTI > At this time, since the hydraulic pressure acts on the communication tube 55 of the sleeve 76, the hook HK is not pinched. Thus, the sleeve 76 is firmly fixed to the lower portion of the bending portion 72 while the hook HK is under hydraulic pressure.

9 (a), when the communicating tube 55 is lowered and the hook HK of the sleeve 76 is hooked on the expanding portion 72, The metal plate 78 of the sleeve 76 is stuck in the communication tube 55 as the inclined surface 72a of the sleeve 72 supports the outside of the hook HK. The coupler 70 is integrally fixed to the communication tube 55 as the metal plate 78 of the sleeve 76 is stuck in the communication tube 55. [

9 (b), since the inclined surface 72a of the expanded portion 72 does not support the outer side of the hook HK when the sleeve 76 is lifted, the coupler 70 does not support the metal plate 78 Can be released from the communication tube 55. [ Accordingly, the coupler 70 can be separated from the communication tube 55.

The filter for purifying water according to the embodiment of the present invention configured as described above is sold with the cover 60 installed on the end of the filter housing 50 as shown in Fig. The filter housing 50 may be sold with the coupler 70 or a cap (not shown) installed in the communication tube 55 after the cover 60 is installed as shown in FIG. That is, filter housing 50 may be sold as a set with cover 60 or as a set with cover 60 and coupler 70 or cap. At this time, the filter housing 50 shields the end portion of the cover 60, and in particular, the rim 64 of the cover 60 shields the end portion in an isolated state, so that the protruding protrusion 53 is concealed, It is not only protected, it also provides a simple aesthetic. Such a filter housing 50 can conceal the projecting step 53 more reliably when the rim 64 of the cover 60 is brought into close contact with the boss 51. [

The cover 60 is gripped by the fingers F1 and F2 as shown in Fig. 6 and then moved along the longitudinal direction of the communication tube 55 when lifted as shown in Fig. 7 (b). At this time, since the fingers F1 and F2 are held in all directions as shown in Fig. 8, the cover 60 receives the grip force (arrows in the drawing) from all directions. The cover 60 is easily grasped because the grip area is expanded by the rim 64 and the rim 64 provides a curved surface area along the circumferential direction so that the fingers F1 and F2 cause pain It does not. Since the outer edge 62 of the cover 60 protrudes to the outside of the rim 64, the fingers F1 and F2 are slightly caught in the rim 62. Thus, the user can provide the grip force as a whole through the four sides of the cover 60, so that the cover 60 can be easily lifted. At this time, the cover 60 transmits a force almost equal to or greater than the conventional lever to the sleeve 76 because the grip force is transmitted as a whole.

The cover 60 detaches the cap or the coupler 70 from the communication tube 55 when the coupling body such as the cap or the coupler 70 shown in the communication tube 55 is coupled. This is explained in more detail as follows.

7, when the cover (60) is moved (lifted), the sleeve (76) slides upward and the outer surface of the communication tube (55) The inner edge of the wedge-fixed metal plate 78 is raised. At this time, the metal plate 78 is separated from the outer peripheral surface of the communication tube 55, and the wedge fixing state is released. Therefore, the coupler 70 is easily separated from the communication tube 55 by the cover 60 in a one-touch manner without a conventional tool.

9, when the coupler 70 is structured as shown in Fig. 9, the sleeve 76 to which the metal plate 78 is fixed is caused to slide upward by the movement (lift) of the cover 60 as shown in Fig. At this time, the metal plate 78 is lifted along the longitudinal direction of the communication tube 55 together with the sleeve 76 in a state where the wedge is fixed, while the hook HK of the sleeve 76 is in its original state, The metal plate 78 is disengaged from the communication tube 55. 9 (a), the hook HK descends together with the communication tube 55 to be inclined to the inclined surface 72a of the tube-expanding portion 72. As a result, As shown in Fig. At this time, the metal plate 78 is fixed to the communication tube 55 as shown in FIG. Accordingly, the coupler 70 is integrally fixed to the communication tube 55.

Otherwise, when the cover 60 is lifted up, the sleeve 76 rises and the metal plate 78 is released from the communication tube 55 as shown in FIG. 9 (b). Therefore, the coupler 70 is easily separated from the communication tube 55 in a one-touch manner.

The filter for a water purifier according to the present invention as described above has a coupler 70 formed to communicate with the outer circumferential surface of the communication tube 55 because the communication tube 55 is communicated with the end of the filter housing 50, It is possible to easily form a coupling body such as a cap or a cap to the communication tube 55 as well as to manufacture both ends of the coupler 70 with the same structure as the conventional one, The end of the filter housing 50 is shielded by covering the end of the filter housing 50 so that the end of the filter housing 50 can be protected from dust or foreign matter, It is possible to move the cover 60 without any additional tool to easily separate the coupling member coupled to the communication tube 55 from the communication tube 55 in a one-touch manner, ) Is defective, the coupler 70 The filter housing 50 can be prevented from being discarded due to the failure of the coupler 70. [

Further, since the area of the finger of the user can be enlarged and provided through the rim of the cover 60, the cover 60 can be easily gripped, and the grip force of the user can be easily transmitted to the cover 60 have.

Since the outer diameter of the cover 60 is larger than the outer diameter of the rim 64 and the rim of the cover 60 protrudes outside the rim 64, the finger is caught by the rim of the cover 60 protruding in the form of a flange The gripping force can be more easily transmitted to the cover.

The end of the rim 64 formed on the cover 60 closely contacts the end of the filter housing 50 to isolate and conceal the protruding end of the filter housing 50. The appearance of the filter housing 50 is simple and beautiful As shown in FIG.

In addition, a boss 51 facing the rim 64 of the cover 60 along the circumferential direction is formed at the end of the filter housing 50 to reliably hide the end of the filter housing 50.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to be illustrative of the present invention and are not intended to limit the scope of the present invention.
