[0070] When water flow enters into the water inlet cavity 13 through the water inlet end 1, the water flow flows from the tap water inlet 25 to the water flow hole 3 through the tap water flow channel 24, so that the water flow flows out from the corresponding water outlet hole 2 through the water hole 8, the flow guide hole 4 and the water outlet channel 5, if the water hole 8 corresponds to the filter outlet hole 28, the other water flow holes 3 cannot make the water flow pass through, at this time, the water flow first enters into the filter core cavity 30 through the filter core inlet hole 31, then is filtered through the filter core body 32, and the filtered water flow flows into the corresponding water outlet hole 2 from the filter outlet hole 28 through the filter core outlet hole 33.

[0071] The setting of the limiting groove 26 and the limiting boss can correspond the position of each tap water inlet 25 on the water distribution plate 23 with each water flow hole 3 when the water distribution plate 23 is installed on the upper shell body 17, can play a positioning role, and can limit the rotation of the water distribution plate 23 on the upper shell body 17, so that the tap water inlet 25 continuously corresponds to the corresponding water flow hole 3, and the up-down and left-right movement of the water distribution plate 23 is limited through cooperation with the filter, thereby playing a limiting role.

[0072] When the filter core shell 29 is installed in the water inlet cavity 13, the lower end surface of the filter core shell 29 presses the water distribution plate 23 on the upper end of the upper shell body 17, and the upper cover body 18 also limits the upward movement of the filter core shell 29 and the water distribution plate 23, thereby completing the fixing of the water distribution plate 23.

[0073] When the auxiliary filter seat 34 is installed between the upper cover body 18 and the upper shell body 17, the auxiliary filter seat 34 and the filter core shell 29 are limited in the water inlet cavity 13 through the upper cover body 18 and the upper shell body 17, so as to prevent the filter core shell 29 from driving the auxiliary filter seat 34 to move upward and separate;

[0074] When the water flow enters from the filter core inlet hole 31 at the top of the filter core shell 29, the filter core inlet hole 31 can preliminarily filter the impurities in the water flow for the first time, the water flow after the first filtration enters the first filtering cavity, and the impurities in the water are filtered again through the auxiliary filter block 36, and the water flow after the auxiliary filter block 36 enters the space of the filter core body through the filter core inlet hole 31, and the water flow is filtered for the third time through the filter core body 32, thereby improving the filtering effect of the water flow and improving the purity of the water after the water flow.

[0075] Through the detachable setting mode, the upper cover body 18 can be regularly removed from the upper shell body 17, and the auxiliary filter seat 34 can be removed from the filter core shell 29, and the filter core body can also be removed from the filter core cavity 30, so that the auxiliary filter block 36 and the filter core body can be replaced or cleaned in time, so as to further maintain the filtering stability of the water flow.

[0076] Through the setting of the extension table 37 and the inner concave surface 38, when the water flow enters the water inlet cavity 13 from the water inlet end 1, the flow direction of the water flow can be guided and divided, so that the entering water flow flows upward to fill the water inlet cavity 13. Compared with not setting the extension table 37 and directly entering the water inlet cavity 13 from the water inlet end 1, the phenomenon that the filter core body or the filter core shell 29 is damaged due to the direct impact of the water flow on the filter shell or the filter core body can be avoided, and the water flow can be more easily guided upward to enter the first filtering cavity or the filter core cavity 30 from the filter core inlet hole 31.

[0077] When the rotating disc 7 is rotated to the position corresponding to the water distribution hole 8, the flow hole 3 and the guide hole 4, the push spring 44 pushes the positioning top block 43 to be clamped and connected with the positioning hole 41, so as to form a rotating resistance and emit a sound, which can prompt the operator.

[0078] The elastic sealing sheet 46 is used to improve the sealing between the position of the guide hole 4 and the lower end surface of the rotating disc 7 when the lower end surface of the rotating disc 7 abuts against the upper end surface of the middle shell body 16.
