In yet another embodiment, the filter assembly 200 does not include the translucent body 220. In this case, the powder filter 210 is accommodated in the support body 230. Accordingly, the shape and structure of the support housing 231 and the support head 233 have a shape and a structure that can accommodate the power filter 210 in place of the light transmitting member 220.

Hereinafter, the power filter according to one embodiment of the present invention will be described in more detail with reference to FIG. 2 and FIG.

FIG. 9 is an exploded perspective view illustrating a powder filter according to an embodiment of the present invention.

The powder filter 210 includes a filter body 240 and a filter cap 250.

The filter body 240 is hollow and includes an inlet region 241, an interior space 243, and an outlet region 245. The filter body 240 is cylindrical and has a circumferential projection 247 at its upper end.

The size (or diameter) of the antibacterial member 300 may be 1 mm or more and 2 mm or less. If the size of the antimicrobial body 300 is less than 1 mm, there is a danger that the antimicrobial body 300 easily flows out from the pouch filter 210 and the size of the antimicrobial bodies 300 is small, . If the size of the antibacterial member 300 exceeds 2 mm, the size of the air gap between the antibacterial members 300 also increases, so that the shape of the water stream from the filter unit 210 is adversely affected and contamination due to the remaining water There is a danger.

The sum of the volumes of the antibacterial bodies 300 is 30% or more and 50% or less of the volume of the internal space 243. If the total volume of the antibacterial bodies 300 is less than 30% of the volume of the internal space 243, there is a problem that the amount of the antibacterial bodies 300 is small and the antibacterial function is weak. When the total amount of the antibacterial bodies 300 is more than 50% 300 occupy too much of the internal space 243, which adversely affects the flow of purified water.

When the filter cap 250 is made of a rubber material, the diameter of the water intake coke coupling hole 259 may be smaller than the outer diameter of the water intake coke.

The intake coke coupling hole 259 may have a tapered structure. In this case, the diameter of the intake coke coupling hole 259 becomes smaller toward the outflow region 245. When the water intake cock 131 is cylindrical, the water intake coke 131 may be inserted into the water intake cock engagement hole 259, thereby applying pressure to the cap body 253 in the horizontal direction. Accordingly, the cap body 253 can be further adhered to the inflow region 241 to further enhance sealing.

A second escape prevention structure (500) is provided at an end of the intake coke coupling hole (259) toward the outflow region (245). The second escape structure (500) includes an inflow hole (520). The purified water flows into the inner space 243 through the inflow hole 520. The inflow hole 520 may have various shapes as long as it can pass the purified water. The size of the inflow hole 520 should be smaller than the size of the antibacterial member 300 to prevent the antibacterial member 300 from being separated.

In another embodiment, a mesh network may be provided above or below the second escape prevention structure 500. In this case, the inflow hole 520 of the second departure prevention structure 500 may be larger than the antibacterial member 300.

The outer surface 261 of the cap body 253 is in close contact with the inflow region 241. [ Particularly when the first diameter D1 of the inflow region 241 is larger than the second diameter D2 of the inner space 243, the bottom portion 263 of the cap body 253 is divided into the inflow region 241 and the inner space 241 243 of the base plate 242. In this case, the cap body 253 can be disposed more stably in the inflow region 241. [ Particularly, when the water intake cock 259 has a tapered structure, pressure is also applied to the bottom portion 263 of the cap body 253 when the water intake cock 131 is inserted into the water intake cock engagement hole 259, The cap body 253 is pushed down to the inner space 243 so that the cap head 251 is moved in the circumferential direction of the filter body 240 It can be prevented from separating from the projection 247.

On the other hand, the filter cap 250 has a structure that can be detachably coupled to the filter body 240.

The filter body 240 is provided with a coupling protrusion 248 and the cap head 251 is provided with a coupling groove 258 in a shape corresponding to the coupling protrusion 248. The engaging projection 248 is inserted into or detached from the engaging groove 258 so that the filter cap 250 is attached to or separated from the filter body 240. A plurality of engaging projections 248 may be disposed at circumferential projections 247 at regular intervals. A plurality of coupling grooves 258 may also be disposed at regular intervals.
