Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

As shown in FIG. 1, the water purifier of the present invention comprises a filter element 1 and a water inlet pipe 11 connected to each filter element 1. The water is fed through the water inlet pipe 11, and hard water is discharged from the faucet through the filter element 1, so that the water purification is completed. In order to replace the filter element 1 in time, a service life reminding device is arranged on the water inlet pipe 11.

The service life reminding device comprises a power supply assembly and a service life reminding assembly, the power supply assembly supplies power to the service life reminding device, the service life reminding device calculates the flow of the filter element 1 and reflects the practical condition of the filter element 1, and therefore the residual service life of the filter element 1 is obtained.

As shown in fig. 2 and 3, the power supply unit includes a rotor 2, a coil 21, and a magnet 3. The water inlet pipe 11 is provided with a rotating wheel cavity 12, and the rotating wheel 2 is rotatably connected in the rotating wheel cavity 12 and is driven by water flow in the water inlet pipe 11 to rotate. The coil 21 is provided on the wheel 2. The magnets 3 are arranged in the water inlet pipe 11 and are positioned at two sides of the rotating wheel 2; as the wheel 2 rotates, the coil 21 cuts the magnetic induction wire to generate electricity. The coil 21 is electrically connected with the life reminding assembly to supply power to the life reminding assembly.

The power supply assembly further comprises a rectifier 4 and a battery 5. The rectifier 4 is electrically connected to the coil 21 to convert the generated alternating current into direct current. The battery 5 is electrically connected to the rectifier 4 to convert the current into chemical energy for storage. The storage battery 5 is electrically connected with the service life reminding device, so that the storage battery 5 serves as a power supply to supply power for the service life reminding device.

In order to achieve the rotating connection of the runner 2, the inlet pipe 11 is provided with a joint 13 which communicates with the runner cavity 12, as is shown in connection with fig. 4. The rotating wheel 2 is fixedly connected with a fixed shaft 22 sleeved in the joint 13. In order to ensure stable connection, at least two bearings are arranged in the joint 13, and the bearings are sleeved outside the fixed shaft 22. The pipe thread of the joint 13 is connected with a transparent cover 14, and the transparent cover 14 is sleeved outside the fixed shaft 22.
