The spiral groove 14 rotates downward clockwise, and the notch at the top of the spiral groove 14 is the inlet, and the notch at the bottom of the spiral groove 14 is the outlet. Sealing slots 15 are symmetrically provided on the inner top wall and the inner bottom wall of the spiral groove 14, and a plurality of winding grooves 16 are provided at equal intervals on the roller wall of the unwinding roller 2, and a plurality of filter element winding grooves 17 and diaphragm winding grooves 18 are provided at equal intervals on the roller wall of the winding roller 3; A filter element roll 19 is wound inside the winding groove 16, and the filter element roll 19 includes a PP filter element 191 and a diaphragm 192. The diaphragm 192 is arranged on both sides of the PP filter element 191, and the diaphragms 192 on both sides of the PP filter element 191 at one end of the filter element roll 19 extending out of the winding groove 16 are in a torn state, and the PP filter element 191 is inserted into the interior of the sealing slot 15 from the inlet of the spiral groove 14 and passes through the outlet of the spiral groove 14 along the sealing slot 15 and is wound in the filter element winding groove 17, and the torn diaphragm 192 bypasses the outer wall of the filter tube 1 and is wound in the diaphragm winding groove 18.

[0016] A driving groove 5 is opened inside the support seat 4, and the bottom of the unwinding roller 2 and the winding roller 3 are fixedly connected with a first rotating shaft 6, the other end of the first rotating shaft 6 is movably inserted into the inside of the support seat 4, and the first rotating shaft 6 extends to the shaft wall inside the driving groove 5, and a first transmission wheel 7 is fixedly sleeved on it. A second rotating shaft 8 is rotatably inserted at the bottom of the support seat 4, and the second rotating shaft 8 extends to the shaft wall inside the driving groove 5, and a second transmission wheel 9 is fixedly sleeved on it. The second transmission wheel 9 is connected to the first transmission wheel 7 through a transmission belt 10, and the second rotating shaft 8 can drive the second transmission wheel 9 to rotate, and the second transmission wheel 9 can drive the two first transmission wheels 7 to rotate synchronously through the transmission belt 10, so that the unwinding roller 2 is driven to unwind through the two first transmission wheels 7, and the winding roller 3 is driven to rewind at the same time.

[0017] The filter tube 1 is fixedly mounted on the top of the support seat 4 , and the unwinding roller 2 and the winding roller 3 are both rotatably plugged into the top of the support seat 4 .

[0018] The top of the filter tube 1 is fixedly connected with a connecting end tube 12 , the top of the connecting end tube 12 is provided with a drainage groove 13 , and the drainage groove 13 is connected with the water channel 11 , and the filter tube 1 can be conveniently connected to the external pipe fitting through the connecting end tube 12 .

[0019] The winding groove 16 and the diaphragm winding groove 18 are located at the same horizontal plane as the inlet of the spiral groove 14, and the filter element winding groove 17 is located at the same horizontal plane as the outlet of the spiral groove 14, which is convenient for inserting the PP filter element 191 wound inside the winding groove 16 from the inlet into the inside of the sealing slot 15, and for winding the PP filter element 191 after use in the filter element winding groove 17 and for winding the diaphragm 192 in the diaphragm winding groove 18.

Since the diaphragm 192 is bonded to the PP filter element 191 at equal intervals by hot pressing, it is more convenient to tear off the diaphragm 192. Then, the PP filter element 191 is inserted into the inside of the sealing slot 15 along the inlet of the spiral groove 14, laid along the spiral sealing slot 15, and extended from the outlet of the spiral groove 14 and its end is wound in the filter element winding groove 17 on the winding roller 3, and the torn diaphragm 192 is wound around the outer wall of the filter tube 1 in the diaphragm winding groove 18 on the winding roller 3; When in use, water will be filtered and purified by the PP filter element 191 arranged inside the sealing slot 15 during the process of passing through the spiral groove 14. After a period of use, when the impurities filtered by the PP filter element 191 inside the sealing slot 15 are saturated, the second rotating shaft 8 will rotate clockwise. When the second rotating shaft 8 rotates clockwise, it can drive the unwinding roller 2 and the winding roller 3 to rotate clockwise synchronously through the transmission wheel group. When the unwinding roller 2 rotates, it can unwind the filter element roll 19 wound inside the winding groove 16. At the same time of unwinding, the winding roller 3 rotates synchronously to rewind. The PP filter element 191 inside the filter element roll 19 will extend to the inside of the sealing slot 15, and the diaphragm 192 will wrap around the filter tube 1, so that the PP filter element 191 and the diaphragm 192 can be automatically separated. When winding, the winding roller 3 can wind the saturated PP filter element 191 into the filter element winding groove 17 and the diaphragm 192 into the diaphragm winding groove 18, so that the PP filter element 191 located inside the sealing slot 15 can be replaced without loss. The replacement of the PP filter element 191 does not need to be disassembled and assembled in the water purifier, so that a single set of filter elements can be used for a longer time, thereby improving the water purification efficiency.
