The hollow core 20 is disposed in the cavity of the connector body 10 and includes a filter cartridge 22 and a holding cartridge 21 . The filter cartridge 22 is correspondingly located at the water outlet 12, one side communicates with the holding cylinder 21, and the other side is closed and provided with a water hole 221 and a sealing gasket 222, wherein the surface where the water hole 221 and the sealing gasket 222 are located is in contact with the joint body The surface where the water outlet hole 13 of 10 is located corresponds to; The friction ring 50 is sleeved on the adjusting knob 30 . The fastener 60 is arranged on the outside of the adjustment knob 30 protruding from the end of the joint body 10 and is screwed to the joint body 10 , that is, the fastener 60 confines the hollow inner core 20 , the adjustment knob 30 and the friction ring 50 to the inner cavity of the joint body 10 middle. In addition, the fastener 60 has an opening, and an end portion of the adjustment knob 30 protruding from the joint body 10 is exposed to the opening. The water sealing mechanism 40 is arranged in the water inlet 11, including a plug 41, a spring 42 and a fixed sleeve 43. The plug 41 is arranged at the joint between the water inlet 11 and the cavity, and is pressed against the holding cylinder 21 by the spring 42, and the fixed sleeve 43 is sleeved on the spring 42 and screwed into the water inlet 11 through the threads on its outer surface. Turning the adjusting knob 30 can drive the hollow inner core 20 to rotate relative to the joint body 10 and the fastener 60 . The holding cylinder 21 is provided with structures such as a first water outlet 211 and an inner concave portion 213 along the outer circumference, and the above structures correspond to the water inlet 11 during rotation to form multiple working states of the water inlet device.

Referring to FIG. 3 to FIG. 4 , when the first water outlet 211 on the holding cylinder 21 corresponds to the water inlet 11 , it is the first state of the water inlet device. In this state, the water flow enters from the water inlet 11 , enters the inside of the holding cylinder 21 and the filter cylinder 22 through the first water outlet 211 , and then flows out from the water outlet 12 into the shower faucet 2 . As shown in Figure 3A, when the holding cylinder 21 rotates until the first water outlet 211 and the water inlet 11 are completely opposite to each other, the water flow is maximum; as shown in Figure 3B, the holding cylinder 21 rotates until the first water outlet 211 is opposite to the water inlet 11. , the water flow is small; as shown in FIG. 3C , when the holding cylinder 21 rotates until the first water outlet 211 and the water inlet 11 gradually deviate to completely non-overlapping, the water flow gradually disappears. The first water outlet 211 is provided with a first bridge 212 along the outer circumference of the holding cylinder 21. The first bridge is integrated with the cylinder wall and separates the first water outlet 211. The end of the plug 41 of the water sealing mechanism 40 has a protruding part 411 , the protruding part 411 abuts against the first bridge 212 during rotation in the first state, and at this time there is a gap between the water sealing mechanism 40 and the water inlet 11 for water to flow in. In this state, the gasket 222 corresponds to the water outlet hole 13 and blocks the water outlet hole 13 . In practical application, when the switch 203 of the shower faucet 2 is turned on, the water inflows of the hot water at the first water inlet 201 and the cold water at the second water inlet 202 are adjusted by turning the adjustment knobs respectively to balance them. In addition, the filter cartridge can have a double-layer or multi-layer mesh structure, and the water flows from the inside of the filter cartridge to the outside, which can filter out impurities and sediment, so that the water entering the shower faucet is clearer.

Referring to FIG. 5 and FIG. 6 , when the inner concave portion 213 on the holding cylinder 21 corresponds to the water inlet 11 , it is the second state of the water inlet device. The inner concave portion 213 is an arcuate surface that is gradually concave inward from the outer circumference of the holding cylinder 21 in the direction of the center of the circle and has a pericentric point 213a.
