As shown in FIG. 1, the water purification device (1) for a jade humidifier according to the present invention includes an upper cover (10) into which polishing wastewater discharged from the jade humidifier flows, and a polishing wastewater flowing in through the upper cover (10). A primary filter unit (20) that primarily filters wastewater to remove relatively large-sized sludge and suspended matter, and fine sludge in polishing wastewater from which large-sized sludge and suspended matter are removed through the primary filter unit (20). A secondary filter unit 30 that filters, a water collection unit 50 that stores reusable purified water filtered through the primary and secondary filter units 30, and a water collection unit 50 that stores purified water stored in the water collection unit 50.

In case of deterioration, the primary filter unit 20 can be conveniently detached, cleaned, and then reused.

In addition, the first filter metal mesh 21 is inclined at a predetermined angle, so that the polishing wastewater flowing in through the wastewater inlet 12 naturally moves downward along the upper side of the first filter metal mesh 21. It is possible to prevent filtration efficiency from being reduced by being filtered and concentrated only on a specific part of the first filter metal mesh 21, and to the upper part of the secondary filter unit 30 located below the primary filter unit 20. By evenly dispersing and discharging the polishing wastewater, the filtering area of the secondary filter unit 30 can be increased, and filtration efficiency can be significantly increased by filtering a large amount of polishing wastewater at once.
