The side wall of the convex tile 66 facing away from the outlet direction of the inclined water tank 214 is provided with a fourth pressure increasing surface 661, which is inclined with respect to the supporting surface 2132 and presses the water flow towards the first gap 200.

The water pressing block 67 corresponds to the inclined water tank 214, that is, corresponds to the protrusion 213, the water pressing block 67 is provided with a pushing surface 671 facing the water outlet direction of the inclined water tank 214, and the pushing surface 671 is inclined relative to the supporting surface 2132 so that the water outlet of the inclined water tank 214 pushes the pushing surface 671 and the abutting surface 641 is away from the supporting surface 2132. The water pressing block 67 is further provided with a third pressurizing surface 672 deviating from the water outlet direction of the inclined water tank 214, the third pressurizing surface 672 inclines relative to the supporting surface 2132 and presses water flow to the water outlet gap, and the water flow in the water outlet gap can rotate along with the rotating piece 60 and finally realizes the rotation of the water outlet curtain. The water pressing block 67 is further provided with a connection surface 673 connecting the pushing surface 671 and the third pressurizing surface 672, and the connection surface 673 is inclined with respect to the support surface 2132. The connecting surface 673 faces the inclined surface of the bump 213 and forms a third gap 400 with the inclined surface, the connecting surface 673 is inclined inward from top to bottom, the pushing surface 671 and the third pressurizing surface 672 are mirror-symmetric, an included angle between the pushing surface 671 and the connecting surface 673 is an obtuse angle, an included angle between the third pressurizing surface 672 and the connecting surface 673 is an obtuse angle, and the third pressurizing surface 672 is also parallel to the fourth pressurizing surface 661.

The working principle is as follows:

the water flow flowing in from the water inlet channel 11 flows to the water passing opening 2211 after being filtered by the filter element 30, flows into the water passing interval 100 through the water passing opening 2211, and further flows into the water passing cavity through the inclined water channel 2111; the water flow guided by the inclined water channel 2111 impacts the impeller 65 to rotate, and then drives the rotating member 60 to rotate, meanwhile, the water flow in the water passing cavity impacts the water pressing block 67 through the inclined water channel 214 to drive the rotating member 60 to rotate, secondly flows into the water outlet gap through the inclined water channel 214, thirdly directly flows into the first water outlet 621 of the central body 62 through the opening of the first water outlet 621, fourthly directly flows to the second water outlet 68 through the opening of the second water outlet 68, fifthly flows into the interval between the adjacent convex tiles 66 through the water passing channel 642 of the turntable 64, sixthly flows into the water outlet gap through the third gap 400, and the water flow flows out from the water outlet 6211 of the first water outlet 621, the water outlet end of the second water outlet 68 and the water outlet gap.

According to the technical scheme, when the rotating member 60 rotates, the first water outlet hole 621 forms inner-ring water outlet, the second water outlet hole 68 and the water outlet gap form outer-ring water outlet, so that a multi-ring water curtain effect is formed, the rotating member 60 can form a rotating water curtain, the rotating water curtain is not easily influenced by eccentricity caused by the rotating speed of the rotating member 60, the water shape of the water curtain is stable, the stable water curtain can be obtained without arranging a complex structure, and the structure is simple and ingenious; especially, when the rotating member 60 is provided with the plurality of second water outlet holes 68, the rotating member 60 itself can form a plurality of stable water curtains, and the water outlet effect is good, and more preferably, as described above, the water outlet 6211 of the first water outlet hole 621 can be designed in different forms, so that the water outlet form of the water outlet apparatus of the present application is diversified, and thus the multi-water-shaped water outlet effect is formed.

When water flows into the inclined water channel 2111 through the water passing interval 100, the water passing area of the inclined water channel 2111 is small, the flow velocity of the water flow is increased, and the water flow is pressurized; when the water flows into the second outlet hole 68 from the water passing cavity, the first pressurizing surface 6311 pressurizes the water flowing into the second outlet hole 68 downward when the rotating member 60 rotates, and the water flows are all subjected to an obliquely downward pressure, which accelerates the water flow in the second outlet hole 68; second pressure boost face 622 makes rivers striking on second pressure boost face 622 on the one hand, and the pressure boost is accelerated to the velocity of water flow, and on the other hand makes second apopore 68 cross the water area at the position that second pressure boost face 622 corresponds and reduces, and the pressure boost is accelerated to the velocity of water flow, also promptly first pressure boost face 6311 and second pressure boost face 622 respectively to the rivers pressure boost in the second apopore 68, therefore the rivers pressure boost effect that second apopore 68 goes out is obvious. The connecting ribs 631 are arc-shaped and protrude forward relative to the rotation direction of the rotating member 60, so that the water flow of the second water outlet 68 rotates more smoothly and is not easy to break up.

When water flows into the inclined water tank 214 from the water passing cavity, the water passing area of the inclined water tank 214 is small, the water flow speed is accelerated, and the water flow is pressurized; when the water flow impacts the pushing surface 671 and the connecting surface 673, the water flow is impacted, the flow speed of the water flow is accelerated, and the water flow is pressurized; because the third pressurizing surface 672 and the fourth pressurizing surface 661 deviate from the water outlet direction of the inclined water tank 214, and incline relative to the supporting surface 2132 and press the water flow to the water outlet gap, wherein the third pressurizing surface 672 can press the water flow to the first gap 200 and the second gap 300, the fourth pressurizing surface 661 can press the water flow to the first gap 200, the water flow is all subjected to a downward pressure, the water flow can flow into the water outlet gap, and the water flow is further accelerated in the water outlet gap by the pressure, so as to realize the pressurization of the water flow in the water outlet gap, and the third pressurizing surface 672 and the fourth pressurizing surface 661 jointly realize the water flow pressurization, so that the water flow pressurization effect in the water outlet gap is obvious.

Therefore, under the condition that the centrifugal force of the rotating part 60 is not changed, the pressurizing effect of the water flow of the second water outlet hole 68 and the water outlet gap is obvious, the control of the opening angle of the rotary water outlet curtain relative to the water outlet direction and the weakening of the phenomenon of flying and throwing towards the periphery are facilitated, and therefore the water flow of the rotary water outlet curtain is more concentrated and full, and the washing effect and the massage effect for a user are better.

The flow guiding surface 611 is arranged to allow the water flow of the second water outlet hole 68 to have a sufficient space to rectify the discharged water into a water curtain shape, and the distance between the parts of the water outlet gap near the water outlet end gradually increases along the water outlet direction, so that the water flow in the water outlet gap has a sufficient space to rectify the discharged water into a water curtain shape.

According to the above technical solution, since the tangential water flow formed by the inclined water channel 214 and the inclined water channel 2111 has the same rotation direction, the rotating member 60 is rotated by the water flow guided by the inclined water channel 2111 impacting the impeller 65, and the water flow guided by the inclined water channel 214 impacting the water pressing block 67, so that the rotating member 60 can also rotate under the action of the low-pressure water flow.

Because the first pressure increasing surface 6311 is inclined backwards from top to bottom relative to the rotation direction of the rotating member, the first pressure increasing surface 6311 is also subjected to resistance of water flow when the water flow inclines upwards, and the water flow pushes the rotating member 60 to float upwards, so that the friction force between the rotating member 60 and the water outlet body 20 is reduced; the pushing surface 671 is inclined relative to the supporting surface 2132 in the direction facing the water outlet direction of the inclined water tank 214, the water flow guided by the inclined water tank 214 can also act on the pushing surface 671, and the pushing surface 671 receives an upward inclined pushing force, so that the abutting surface 641 can be pushed to be away from the supporting surface 2132; since the connection surface 673 is close to the pushing surface 671 and is inclined relative to the supporting surface 2132, when the water flows out from the inclined water tank 214, the water flow guided by the inclined water tank 214 can also act on the connection surface 673, and the connection surface 673 receives an upward inclined pushing force, so that the abutting surface 641 can be pushed away from the supporting surface 2132. Preferably, since the third pressurizing surface 672 and the fourth pressurizing surface 661 are both away from the water outlet direction of the inclined water tank 214, the third pressurizing surface 672 and the fourth pressurizing surface are both inclined with respect to the supporting surface 2132, and the third pressurizing surface 672 and the fourth pressurizing surface 661 both pressurize the water flow to the water outlet gap, when the rotating member 60 rotates, the third pressurizing surface 672 and the fourth pressurizing surface 661 are both subjected to the resistance of the water flow which is inclined upwards, and the water flow further pushes the rotating member 60 to float upwards. Therefore, the first pressurizing surface 6311, the pushing surface 671, the third pressurizing surface 672, the fourth pressurizing surface 661, and the connecting surface 673 are provided to float the rotor 60 by the water flow, thereby reducing the friction between the contact surface 641 and the supporting surface 2132. Preferably, due to the third gap 400, the friction between the connection surface 673 and the inclined surface 2131 of the protrusion 213 is further reduced, so that the friction applied to the rotation member 60 during the rotation is small, and the rotation member 60 can float upward to rotate rapidly under the high-pressure water flow, and the rotation member 60 can also rotate rapidly under the low-pressure water flow due to the dual actions of the inclined water channel 2111 and the inclined water channel 214, that is, the rotation member 60 is not affected by the water pressure.
