<<Example 2》

In the embodiment, the circuit principle of the control module 16 is shown in FIG. 6. The control module can count two times. The first time is the total usage time after the faucet is installed. Since the installation of the faucet and the use of the water purifier are synchronized, the usage time of the two is the same. Therefore, by accumulating the total usage time of the faucet, the total usage time of the water purifier filter can be obtained. The second time is the accumulation time of the water flow through the faucet. When the handle is opened, the faucet is in the water-passing state. At the same time, the handle triggers the switch, closes the circuit, and the control module begins to accumulate the water-passing time; when the handle returns, the faucet is closed. The water flow, at the same time, the circuit is disconnected, and the control module suspends the accumulated water flow time. The control module sets the usage time of the water purifier filter. When it is within the set use time, the indicator light displays a green light; and when one of the above two times reaches the set time, the prompt light starts to display a red light or a yellow light. In order to remind the user that the filter element of the water purifier has reached the end of its service life, it should be replaced in time.

The accumulation of the above two times is synchronized, whichever comes first. For example, when the user goes out for a few months, although the water flow time of the faucet is small, but the cumulative use time of the filter element has expired, the filter element also needs to be replaced. For example, the user has a higher frequency of water use and a longer water flow time of the faucet. Although the cumulative use time of the filter element has not yet arrived, but the water supply time of the faucet has reached the set time, the filter element also needs to be replaced. Therefore, the present embodiment can accurately understand the service life state of the water purifier filter element by double time judgment.
