Since the tooth surface of the baffle tooth faces counterclockwise, it uses the reaction force of the water while hindering the clockwise flow of water to promote the counterclockwise rotation of the water wheel. The mouth flows between the cylinder body and the ceramic filter element for filtering; the other part of tap water passes through the water wheel, the polygonal transmission tube, the fixed intubation tube in turn, flows into the inner cavity of the connecting plate, and is sprayed by the brush head fixedly connected to the outer wall of the connecting plate. out, flows into between the cylinder body and the ceramic filter element, and is filtered; the filtered water flows into the drinking water channel from the filter element joint at the lower end of the ceramic filter element, and finally flows out from the drinking water joint.

Brushing, to achieve the purpose of automatically cleaning the ceramic filter element relying on the power generated by water pressure; when the drinking water outlet faucet or non-drinking water outlet faucet is in the open state, the water wheel rotates counterclockwise, and the resistance of the coil spring gradually increases. When the resistance is equal to the water inlet impulse acting on the side wall of the water wheel, the water wheel will stop rotating, and the ceramic filter element will also stop rotating; Under the restoring force of the coil spring, the water wheel rotates clockwise, which drives the transmission connecting sleeve to rotate. Since the lower edge of the incomplete gear is formed with one-way locking teeth, when the transmission connecting sleeve rotates clockwise, the incomplete gear will not rotate; until The coil spring is restored to its original shape, and the drinking water outlet faucet or non-drinking water outlet faucet is turned on, and the brush assembly cleans the ceramic filter element again; since only a part of the incomplete gear has active locking teeth, the active locking teeth and driven locking teeth of the incomplete gear When the teeth are meshed and rotated, the driving of the driven latch teeth will only drive the corresponding brush assembly to rotate clockwise to clean the ceramic filter element, so as to achieve the purpose of not excessively cleaning the ceramic filter element. The present invention adopts the method of parallel connection of multiple filter element components, which improves the water outlet speed of drinking water, shortens the waiting time for users to receive drinking water, and does not need to use pressure barrels to store water like reverse osmosis water purifiers. The structure is simple and compact, and it is easy to use And the service life is relatively long.

In addition, the controller and the electric regulating valve are powered by the power generation device driven by tap water, and there is no need to supply power for them separately, which is energy-saving and environmentally friendly.
