The positioning frame 54 includes an outer connecting ring 541 and an inner connecting ring 544; more than two connecting rods 543 are formed between the inner connecting ring 544 and the outer connecting ring; a U-shaped rod 547 is formed on the outer side wall of the inner connecting ring 544; a pair of opening rods 546 are formed at one end of the inner connecting ring 544, which is far away from the U-shaped rod, between the outer connecting ring and the inner connecting ring; the U-shaped rod, the inner connecting ring, the opening rod and the outer connecting ring jointly form an opening for the connecting rod to be clamped into the inner connecting ring, and the connecting rod is clamped into the inner connecting ring and then attached to the opening rod.
The gear rod is positioned on one side of the outer connecting ring far away from the opening rod; positioning protrusions 542 are uniformly formed on the outer wall of the outer connecting ring 541 along the circumferential direction.
The lower end of the side wall of the water wheel installation groove 23 is provided with a positioning groove 25 which is matched and positioned with the positioning protrusion 542. Because the diameter of the connecting rod is smaller than that of the transmission rod, when the positioning frame is installed, the position of the hand-held outer connecting ring close to the spreading rod is pulled outwards, and when the connecting rod is completely installed in the inner connecting ring, the position of the hand-held outer connecting ring close to the spreading rod is pressed inwards, so that the water wheel and the positioning frame are longitudinally fixed.

Install low voltage switch on the ceramic filter upper reaches pipeline, install high voltage switch on the pipeline between pressure bucket and the reverse osmosis membrane filter, install the booster pump on the upper reaches pipeline of reverse osmosis membrane filter, low voltage switch, high voltage switch and booster pump respectively with the controller electric connection.
And a hydraulic sensor is installed on a downstream pipeline of the ceramic filter, the hydraulic sensor and the electromagnetic valve are respectively and electrically connected with the controller, and when the hydraulic sensor detects that the pressure value is lower than a set value, the controller controls the electromagnetic valve to be opened for 10-60s and then closed.
The invention uses the self-cleaning ceramic filter to replace PP cotton for removing particle impurities, thereby reducing the frequency of replacing the filter element and being beneficial to prolonging the service life of other filter elements.
When the water is produced by the water purifier, the water flows into the cylinder of the ceramic filter from the water inlet connector, is filtered by the ceramic filter element and then flows out from the water outlet connector, the water flow channel and the water outlet connector;
the water flowing in from the water inlet port is sprayed out along the tangential direction of the water wheel through the water spraying port, and the impact force is applied to the water wheel body, so that the water wheel body, the transmission rod and the driving gear rotate as a whole; the driving gear is in meshing transmission with the transmission gear, so that a driving wheel fixedly connected to the lower end of the transmission gear is in transmission connection with the first transmission rubber wheel and the second transmission rubber wheel through friction force respectively to drive the first transmission rubber wheel and the second transmission rubber wheel to rotate in the same direction; polygonal transmission holes which are matched with the transmission heads at the upper parts of the ceramic filter cores for transmission are formed between the first transmission rubber wheel and the second transmission rubber wheel, so that the first filter core component and the second filter core component are driven to rotate in the same direction; because the outer walls of the two ceramic filter elements are abutted, when the two ceramic filter elements rotate in the same direction, the movement directions of the abutted positions are opposite, so that the outer walls attached with impurities can be mutually abraded, and the outer walls of the ceramic filter elements are prevented from being blocked; the water mixed with impurities flows out through a waste water outlet joint;
because the upper end and the lower end of the first ceramic filter element and the second ceramic filter element are respectively and fixedly connected with the upper annular magnet and the lower annular magnet, the two adjacent annular magnets attract each other; when the ceramic filter elements are worn, the outer diameters of the ceramic filter elements are reduced, and the two ceramic filter elements can always keep an abutting state under the magnetic force generated by the annular magnet.
When the ceramic filter element is abraded to the outer diameter equal to the outer diameter of the annular magnet, the annular magnet is abutted, the ceramic filter element is not abraded any more, when a user opens the water tap to find that the water outlet port does not have water to flow out, or after the electromagnetic valve is opened to drain the ceramic filter, the hydraulic sensor detects that the pressure is still lower than a set value, and the side wall of the ceramic filter element is blocked by impurities completely and needs to be replaced.
