2. Description of the Related Art Conventionally, ordinary drinking water has been filtered by a water purifying cylinder filled with activated carbon, an ion exchange resin or other filtering material to filter impurities in water. In a general water purifier, drinking water is filtered through a water supply pipe of the water purifier to filter out relatively large solid impurities through the pores of natural fibers, scientific fibers, or foam, and then exudes to activate carbon or ion exchange resin. Small solid impurities in water were adsorbed on various filter materials, discharged from a nozzle and used for drinking.

[0003]

[Problems to be Solved by the Invention] The longer the water passes through the filter medium in the water purification cylinder and the more slowly it is filtered, the more efficiently impurities in the water can be adsorbed to the filter medium. The purification effect of is enhanced. Therefore, there has been a demand for a water purifier that does not change the volume of the water purifier or that can be downsized and that has a high water purification effect.

The configuration of the present invention has been described above. Next, the actual water purification function will be described. The water from the water source passes through two joint filters (20) to filter out relatively large solid impurities in the water, and then the spiral filter (12).
Add to. It is gradually removed in the long spiral filter (12) and reaches the lower part of the case (11) through the water conduit (13). And as the water level rises, the case (1
1) and the spiral tube (120) and the water conduit (13) are further purified by a filter medium (14) to remove minute impurities in the water, and then a filter to be fitted in the nozzle (112) ( The last filtration is completed at 123), and water is discharged from the nozzle (112).

Next, a second embodiment of the present invention will be described. As shown in FIGS. 5 and 6, the water purifier (5) has a water purification tube (50) and a joint type filter (60), and the water purification tube (50) is mainly a case (51) and a waveform filter (52).
And activated carbon (53). A water supply pipe (511) is provided on the side surface of the case (51) and the case (5) on the opposite side is provided.
1) A nozzle (512) having a filter (523) fitted therein is fixed to the side surface.

Further, as shown in FIG. 6, the openings (521) (52) of the corrugated tube (520) of the corrugated filter (52).
Filters (523) are fitted on the inner surfaces of 2).
Fit in. The space between the two fitting filters (523) inside the corrugated pipe (520) is filled with a filter material (524), and the opening (521) of the corrugated pipe (520) is inserted into the case (51) of the water supply pipe (511). And the other opening (522) extends to the bottom of the case (11). The gap between the case (51) and the corrugated filter (52) is filled with a filter material (53). On the outer edge of the outer end of the water conduit (511), a joint type filter (60) is fitted or screwed. A coupling tool (61) is fitted to the rear end of the joint type filter (60) to be used for coupling with a water source such as a faucet.

The second embodiment has a simplified structure of the first embodiment. The second embodiment has a smaller number of fitting filters than the first embodiment, and only one water pipe is provided. The spiral filter (12) is used in the first embodiment, and the waveform filter (52) is used in the second embodiment. The functionality is similar in the two embodiments.

[0015]

The relatively large solid impurities of water from a water source such as tap water are quickly removed by the non-woven fabric in the joint type filter because the joint type filter is fixed to the outer end of the water conduit by the screw thread. Easy to remove, easy to replace. Further, by providing a plurality of filters, the filtering effect is enhanced, and the life of the filter and the filtering material inside the water purification cylinder is extended.

After the filtration with the joint type filter, the filtration is carried out with the filter fitted in the water purification cylinder and the spiral filter or the corrugated filter, and the filter material in the gap between the case and the spiral or corrugated filter. The long filtration process of the spiral filter or the corrugated filter takes a sufficient time for the fine particles of impurities in the water to adhere due to the filter medium (ion exchange resin or activated carbon) filled inside the filter, and the purification action is enhanced. It in this way,
In a certain filtration space, it is possible to provide water that is very suitable for drinking through several types of filters and through a long filtration process.
