The water flow is filtered through the inner filter 7, the middle filter 8 and the outer filter 9 in sequence, wherein the water flow flows from the outer side of the inner filter 7 to the inner side, and then flows from the inner side of the inner filter 7 to the outer side to realize secondary filtration. Specifically, the water flow enters the inner side from the outer side of the inner filter 7, which is the first filter, to form a primary filtration, and then flows from the inner layer of the inner filter 7 to the outer side to form a secondary filtration, and then flows from the middle filter 8, which is the second filter, to the outer side to form a tertiary filtration, and finally flows from the inner side of the outer filter 9, which is the third filter, to the outer side to form a fourth filtration.

[0030] To elaborate further, an inner water inlet connection port 10 is provided at a position corresponding to the water inlet port 3 on the middle filter screen 8, and an outer water inlet connection port 11 is provided at a position corresponding to the water inlet port 3 on the outer filter screen 9. The water inlet port 3, the outer water inlet connection port 11 and the inner water inlet connection port 10 are adjacent to each other, and each port is coaxially arranged, thereby ensuring the reliability of the installation and matching of the three-layer filter screen. The most important thing is to ensure that the order in which water flows through the three-layer filter screen must be consistent. The structure involved in this effect is stated in the text below.

[0031] In further detail, the inner filter screen 7 has a radially extending baffle 12 on the peripheral wall and above the inner water inlet connection port 10, the middle filter screen 8 has a water stop ring 13 on the peripheral wall, the inner water inlet connection port 10 is opened on the water stop ring 13, the baffle 12 abuts against the upper part of the water stop ring 13, and the lower part of the water stop ring 13 has a water stop platform 14 that shrinks and extends toward the inner filter screen 7, and the water stop platform 14 abuts against the inner filter screen 7, the water stop ring 13, the baffle 12 abuts against the inner filter screen 7, and the water stop ring 13 and the baffle 12 abut against the inner filter screen 7. 12 and the water-blocking platform 14 surround and form a water inlet chamber 15 for water flowing through the inner water inlet connecting port 10. The water flows into the water inlet chamber 15 after passing through the inner water inlet connecting port 10. In order to prevent the water from flowing directly to the middle filter screen 8, the baffle 12 and the water inlet chamber 15 are provided. Therefore, the water can only enter the middle filter screen 8 after the secondary filtration of the inner filter screen 7 and finally flow out after the fourth filtration of the outer filter screen 9, thereby achieving the effect of multiple filtration.
