One end of the winding shaft is connected with a driving mechanism. The cleaning mechanism is provided with multiple liquid spraying openings for spraying a cleaning fluid to the filter cloth located in the cloth-transmitting path during winding.

Provided by the present invention is a faucet water purifier for filtering a raw water, which comprises a control valve and a filtering device, wherein the filtering device defines a first communicating opening and a second communicating opening, the control valve comprises a valve body and a valve core, wherein the valve body defines a valve cavity, a first opening, a second opening, a third opening, a raw water inlet and a draining opening, wherein the valve core is disposed inside the valve cavity, wherein the first opening is communicated with the first communicating opening of the filtering device, the second opening is communicated with the second communicating opening of the filtering device, the third opening is communicated with a water outlet of the filtering device, and the raw water inlet of the valve body is adapted to be communicated with a raw water source.

A filtration device efficiently sizes removal of unnecessary substances adhering to and deposited on a filter medium of a filter element during filtration and backwashing (cleaning) from target (non-filtered) substances. The filter element captures substances in a fluid on one surface of a filter medium. The captured substances are separated from the filter medium during backwashing. A brush moves relative to the one surface of the filter medium and assists in separating the captured substances and sifting during the relative movement. The backwashing starts when a differential pressure between both surfaces of the filter medium exceeds a predetermined value, or the like while performing the filtration, and returns to filtration after the differential pressure is eliminated or after a predetermined time elapses. The brush sifts the unnecessary substances from the captured substances and passes the removal to the other surface side during the filtration.
