Title:
WATER FILTER FAUCET HAVING FILTER LIFE DETERMINING FUNCTIONALITY
Document Type and Number:
WIPO Patent Application WO/2017/063462
Kind Code:
A1
Abstract:
A water filter faucet having a filter life determining functionality comprises a faucet body (10) having a valve disposed therein. A rotatable handle (11) is arranged on the faucet body (10) and configured to control an operation of the valve. A monitoring device (12) is arranged on the rotatable handle (11) and electrically connected to a control circuit configured to receive a monitoring signal from the monitoring device (12) and count a time. The control circuit is connected to a warning device (13) configured to warn of that the filter life is to an end. By adopting the monitoring device (12) and the control circuit to compute a service life of a filter and to determine a time limit when the service life is terminated, the embodiment can prevent the filter from being replaced too soon, reducing a cost of using the water filter faucet, while preventing a user from using an unserviceable filter scrap, ensuring water hygiene of a user.
