  • Publication number: 20070023332
    Abstract: An automatic supply filtered water adapter has a filter device to filter the inflowing water and a sensing and supplying device to supply filtered water when its sensor senses an object. The adapter comprises an infrared sensing water supplying device and a water filter connected to the water supplying device by a three-way connecting tube equipped with a water flow controlling device, being a spherical valve controlling the flow direction by a switch, whereby the external infrared sensing water supplying device can eject unprocessed water and filtered water without literally touching the adapting system.
