FIG. 1 is an external perspective view for explaining a filter assembly according to the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a side sectional view of FIG.

As shown in FIGS. 1 to 3, the housing head 10 is provided with a first port 11 and a second port 12 for liquid inflow and outflow. The second flow path 12a extends inward from the second port 12 and the second flow path end 13 which is the end of the second flow path 12a opens upward.

Although the second flow path end portion 13 protrudes upward in the figure, the second flow path end portion 13 is only required to open upward and does not necessarily protrude upward. In order for the filter 60 to be centered, it is preferable that the second flow end portion 13 is located at the center portion of the housing head 10. [

A fastening socket (20) is formed along the edge of the housing head (10) so as to extend upwardly of the housing head (10). The fastening socket 20 may be detachably assembled to the housing head 10 or formed integrally with the housing head 10. In the drawing, the integrated type is shown.

The lower end of the housing 30 is screwed to the fastening socket 20 so that a closed space is formed in an upper space of the housing head 10. The upper end of the housing 30 is closed and the lower end thereof is opened. The fastening between the housing 30 and the fastening socket 20 may be fastened not only by a screw type but also by various other known methods. In the case of FIG. 4, another case is shown as being fastened through the clamp 80.

The housing 30 may be made of transparent or semitransparent synthetic resin material such as polycarbonate (PC) or acrylic material.

The filter fixing lower cap 40 is provided to close the second flow path end portion 13 and includes a through hole 42 connected to the second flow path 12a.

When the through hole 42 is formed on the flat surface of the filter fixing lower cap 40, the through hole 42 can not occupy a large portion. Therefore, the filter fixing lower cap 40 is provided with the projecting portion 41 It is preferable that the through hole 42 is formed in the side wall of the protruding portion 41 to increase the charge area of the through hole 42. [ The larger the area occupied by the through hole 42, the more advantageous is the amount of water introduced.

The filter fixing lower cap 40 may be formed integrally with the second flow path end portion 13 through welding or the like. In order to facilitate understanding of the internal structure of the filter, (13). ≪ / RTI > Of course, the filter fixed lower cap 40 may be detachably fastened to the second flow path end portion 13 by a screw or the like.

The filter fixing rod bar 50 is installed vertically upwards in the filter fixing lower cap 40. It is preferable that a screw groove 50b is formed at the bottom of the filter fixing rod bar 50 for the convenience of manufacture and disassembly and assembly so that the filter fixing rod bar 50 is inserted into the protrusion 43 while being threadedly inserted .

The filter 60 has a hollow space 61 at the center thereof. The filter 60 is fitted into the filter fixing rod bar 50 through the hollow passage 61 and is installed so that the bottom of the filter 60 touches the filter fixing lower cap 40. At this time, the through hole 42 of the filter fixing lower cap 40 should be located in the hollow passage 61.

The filter fixing upper cap 70 is fastened to the upper end of the filter fixing rod bar 50 so as to press downward for the filter 60 while blocking the hollow passage 61. In this case, as the filter fixing upper cap 70 is turned, it is preferable that the filter fixing upper cap 70 is further lowered so that the bottom surface of the filter fixing upper cap 70 is closely attached to the upper end of the filter 60 For this purpose, it is preferable that a screw groove 50a is formed at the upper end of the filter fixing rod bar 50 so that the filter fixing upper cap 70 and the filter fixing rod bar 50 are screwed together.

When the filter fixing upper cap 70 is turned, the filter fixing upper cap 70 is screwed to the filter fixing rod bar 50 and descends downward, whereby the pressing force is applied to the filter 60 from top to bottom . Therefore, the upper end of the filter 60 is closely attached to the filter fixed upper cap 70, and the bottom of the filter 60 is closely adhered to the filter fixed lower cap 40. It is preferable to provide the upper gasket 65 and the lower gasket 64 at the upper and lower ends of the filter 60 in order to prevent water from leaking out from the close contact.

The upper gasket 65 and the lower gasket 64 are preferably inserted into the hollow pipe 61 in a tubular shape so that the upper gasket 65 and the lower gasket 64 have a shape rising from the shoulder portion of the hollow pipe 61. The reason why the filter 60 is inserted into the hollow 61 is to prevent the filter 60 from collapsing toward the hollow 61. The reason why the shoulder of the hollow 61 is to be lifted up is that the upper gasket 65 are in close contact with the filter fixing upper cap 70 and the lower gasket 64 is in close contact with the filter 60 in the filter fixing lower cap 40 so that the sealing can be performed more easily.

It is preferable that the upper gasket 65 and the lower gasket 64 come into contact with the filter fixing upper cap 70 and the filter fixing lower cap 40 with a slight elasticity such as an O-ring and a flexible material. Another reason that the upper gasket 65 and the lower gasket 64 must climb over the shoulder of the hollow 61 is because the filter 60 itself is formed by laminating a thin filter paper, And to prevent the filter 60 from being locally crushed at a position where it touches the filter fixed top cap 70.

A first flow path is extended from the first port 11 to the housing head 10 and a first flow path end portion 51 which is an end of the first flow path is opened to the upper side of the closed space. Respectively.

  It is preferable that an air discharge hole 14 and a water discharge hole 15 are formed in the vicinity of the first port 11 and the second port 12 to be able to be clogged and opened by a cap 16. The air discharge hole 14 and the water discharge hole 15 may be integrated into one.

The operation principle of the filter assembly according to the present invention will now be described.

The water that has entered the first port 11 flows through the first flow path end 51 to the outside of the filter 60, the hollow path 61 inside the filter 60, the through hole 42, The flow path end portion 13, the second flow path 12a, and the second port 12 to the outside.

At this time, since the hollow passage 61 of the filter 60 is tightly closed by the filter fixed lower cap 40 and the filter fixed upper cap 40, water leaks from the joint portion of the filter 60 It does not come out.

Of course, the first port 11 serves as an outlet port and the second port 12 serves as an inlet port. However, filtering may be performed in the reverse order of the above. However, for the filtering efficiency, 11 is an inlet port, and the second port 12 is an outlet port.

As described above, according to the present invention, since the filter 60 is not fastened directly to the housing 30 but is fastened independently of the housing 30, the housing 30 is fastened to the fastening socket 20 by a nail or clamping method, It is possible to impart hermeticity to the fastening portion of the filter 60 through the filter fixing upper cap 70 and the filter fixing lower cap 40 irrespective of the strength of the fastening. Therefore, even if the housing 30 is made of a transparent polymer material that is fragile with respect to metal, there is no problem in securing the hermeticity with respect to the fastening portion of the filter 60.

The above-described filter assembly is not limited to the configuration and the method of the above-described embodiments, but the embodiments may be configured such that all or some of the embodiments are selectively combined so that various modifications can be made It is possible.
