This solution utilizes the characteristic that when the flow switch 207 and the hall element 209 are aligned, the hall element 209 will receive an electromagnetic signal, thereby identifying that the flow switch 207 is in different positions. However, when the hall element 209 receives the electromagnetic signal, it can be regarded that the filter element has been replaced due to the dirt, and a prompt signal for replacing the filter element is sent. By arranging a plurality of hall elements 209, a variety of indications can be provided that the filter cartridge is clean, dirty, and must be replaced, depending on the position of the flow switch 207.
