Water quality-upgrading device

A water quality-upgrading device comprising:

• a container having an inner peripheral wall defining a receiving chamber and two opposite ends respectively defining an inlet and an outlet both are in spatial communication with the receiving chamber;
• a support member inwardly protruded from said inner peripheral wall of said container and located above said outlet;
• at least two water molecule refinement layers disposed in said receiving chamber, one of said water molecule refinement layers serving as a first water molecule refinement layer and the other one of said water molecule refinement layers serving as a second water molecule refinement layer, said first water molecule refinement layer being a honey comb filter fabricated from Far-infrared radiation emitting ceramic material and disposed on said support member, said second water molecule refinement layer being a honey comb filter fabricated from Far-infrared radiation emitting ceramic material or consisting of a plurality of Far-infrared radiation emitting ceramic particles fabricated from Far-infrared radiation emitting ceramic material and disposed on said first water molecule refinement layer;
• two filtering sheets disposed at said inlet and said outlet of said container respectively;
• and
• wherein, when water flows into said receiving chamber, said water molecule refinement layers are capable of converting water into finer water molecules so as to spread said finer water molecules on an oil sludge stained on a substance such that said finer water molecules penetrate into gaps formed between the oil sludge and an external surface of the substance, thereby reducing contact area amount and simultaneously weakening a bonding property between the oil sludge and the external surface of the substance to facilitate removal of the oil sludge off the substance by means of a wiping cloth.
