The water source through the catalyst enters into the inside of water collecting cavity 32, then enters into the inside of water tank 2 through water collecting cavity 32, and the water source filters through first filter screen 23 at first like this, and the water source after the filtration filters through second filter screen 25 once more, and circulating water pump 5 will filter the water source pump sending after like this to can make water source cyclic utilization, reach the effect of energy saving, the water source after purifying is environmental protection more simultaneously.
Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
