SMART WATER FILTER SYSTEM

摘要

Various examples are provided for smart water filter systems. In one example, a smart water filter system includes a solenoid valve (or other electrically operated valve) in a water supply line of a faucet, and a filter bank coupled to the water supply line. Activation of the valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet. In another example, a smart water filter system includes a three-port solenoid (or electrically operated) valve coupled to a faucet, and a filter bank coupled to the water supply line and to a second inlet port of the three-port solenoid valve. Activation of the three-port valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet.

1. A smart water filter system, comprising:
a solenoid valve in a water supply line of a faucet, where the solenoid valve is a normally-open solenoid valve; and a filter bank having an inlet coupled to the water supply line before an inlet port of the solenoid valve and an outlet coupled to the water supply line after an outlet port of the solenoid valve; where activation of the solenoid valve stops flow of unfiltered water through the faucet while allowing flow of only filtered water through the faucet.
