[0015] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In technical solution 1, the rotating part of the present invention is provided with a second water outlet hole located between the first water outlet hole and the water outlet gap; the second water outlet hole is arranged around the first water outlet hole, so when the rotating part rotates, the first water outlet hole forms an inner circle of water outlet, and the second water outlet hole and the water outlet gap both form an outer circle of water outlet, thereby forming a multi-circle water curtain effect, and the rotating part of the present invention itself can form a rotating water curtain, so it is not easily affected by the eccentricity caused by the rotation speed of the rotating part, the water shape of the water curtain is stable, and a stable water curtain can be obtained without setting a complex structure, and the structure is simple and ingenious; especially when the rotating part is provided with multiple second water outlet holes, the multiple second water outlet holes surround the first water outlet hole from the inside to the outside, and the rotating part itself can form multiple circles of stable water curtains, and the water outlet effect is good.

[0017] 2. In the second technical solution, the structural setting of the rotating part is simple to use and easy to produce and process. The setting of the connecting part not only makes the structure of the rotating part stable, but also the first pressurizing surface is inclined backward from top to bottom relative to the rotation direction of the rotating part, so that the first pressurizing surface can pressurize the water flowing into the second water outlet downward when the rotating part rotates, thereby making the water flow of the rotating water curtain of the second water outlet more concentrated and full, and the flushing effect and massage effect on the user are also better. When the centrifugal force of the rotating part remains unchanged, it is also beneficial to reduce the opening angle of the rotating water curtain relative to the water outlet direction and reduce the phenomenon of flying to the periphery. Moreover, the first pressurizing surface is also subject to the resistance of the water flow tilted upward, and the water flow pushes the rotating part to float up, thereby reducing the friction between the rotating part and the water outlet body, thereby ensuring the rotation speed of the rotating part.

[0018] 3. In technical solution three, the connecting ribs are arc-shaped, so that the water flow of the second water outlet rotates more smoothly and is not easily broken up; and the arc-shaped connecting ribs further increase the area of ​​the first pressurizing surface, thereby enhancing the pressurizing effect on the water flow of the second water outlet.

[0019] 4. In technical solution four, the setting of the second pressurizing surface, on the one hand, makes the water flow hit the second pressurizing surface, and the water flow velocity is accelerated and pressurized; on the other hand, the water flow area of ​​the second water outlet corresponding to the second pressurizing surface is reduced, and the water flow velocity is accelerated and pressurized, thereby further pressurizing the water flow of the second water outlet when the rotating part rotates, and further making the water flow of the rotating water curtain of the second water outlet more concentrated and full, and the flushing effect and massage effect on the user are also better.

[0020] 5. In technical solution five, the second pressurizing surface extends in the circumferential direction, so that the contact area between the second pressurizing surface and the water flow is larger, thereby further enhancing the pressurizing effect on the water flow of the second water outlet.

[0021] 6. In technical solution six, the setting of the guide surface allows the water flow from the second water outlet to have enough space to be rectified and discharged into a water curtain shape.

[0022] 7. In technical solution six, the spacing 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 enough space to be rectified and discharged into a water curtain shape.

[0023] 8. In the eighth technical solution, the tangential water flow formed by the inclined water trough and the inclined water channel rotates in the same direction, so that the rotating part is rotated by the impact of the water flow guided by the inclined water channel on the one hand, and by the impact of the water flow guided by the inclined water trough on the other hand, so that the rotating part can also rotate under the action of the low-pressure water flow; at the same time, the water flow guided by the inclined water trough can also act on the pushing surface to push the abutting surface away from the supporting surface, thereby reducing the friction between the abutting surface and the supporting surface, that is, reducing the friction force on the rotating part, so that the rotating part can float under the high-pressure water flow and rotate rapidly Under low-pressure water flow, the rotating part can also rotate rapidly due to the dual effects of the inclined water channel and the inclined water trough, that is, the rotation of the rotating part is not affected by the water pressure; when the water flows into the inclined water trough, the water flow area of ​​the inclined water trough is small, the water flow speed is accelerated, so that the flow velocity of the water flow in the water outlet gap is enhanced. Therefore, the water flow in the water outlet gap has a large initial water outlet velocity along the water outlet direction, the pressurization effect is obvious, and there is enough space to rectify the water outlet into a water curtain shape, so that the water flow of the rotating water outlet water curtain is more concentrated and full, and the flushing effect and massage effect on the user are also better.

[0024] 9. In technical solution nine, the structure of the rotating part is simple and the rotating function is reliable; the water pressure block is convexly arranged on the convex tile, and the structure is simple and practical; the rotating part body and the water outlet hole form a first gap, and the part of the convex tile located below the water pressure block cooperates with the water outlet hole to form a second gap. The first gap and the second gap are connected to form a water outlet gap. When the water flows into the first gap from the inclined water trough, the water flow area is reduced and the water flow velocity is increased, so that the water flow in the water outlet gap has a larger initial water outlet velocity along the water outlet direction, and the pressurization effect is obvious. When the centrifugal force of the rotating part remains unchanged, it is beneficial to reduce the opening angle of the rotating water outlet water curtain relative to the water outlet direction and weaken the phenomenon of flying to the periphery. , so that the water flow of the rotating water curtain is more concentrated and full, and the flushing and massage effects on the user are also better; the spacing of the first gap close to the water outlet end gradually increases along the water outlet direction, which is conducive to the formation of a water curtain, thereby achieving a water curtain effect with a small external angle; the turntable is also provided with a water groove located between the impeller and the body, and the water groove is connected to the gap between adjacent convex tiles, that is, the water flow through the water cavity can also flow from the water groove to the gap between adjacent convex tiles, and a relatively thick water curtain part can be formed at the gap between the convex tiles, and the flushing force is greater, so that the user can have a pulse-like massage experience when the water curtain is rotating.

[0025] 10. In technical solution 10, the structural setting of the water outlet device is simple and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] See also Figure 1-10 , Figure 1-10 A stable water curtain outlet device is shown, comprising a seat body 10, a water outlet body 20, a filter element 30, a first sealing ring 40, a second sealing ring 50 and a rotating element 60.

[0045] The seat body 10 is a tubular structure with a step hole therein, wherein the small hole of the step hole constitutes the water inlet 11, the large hole of the step hole constitutes the accommodating chamber 12, and the hole shoulder 13 of the step hole forms the bottom of the accommodating chamber 12, so that the water inlet 11 and the accommodating chamber 12 are connected; the inner wall of the accommodating chamber 12 is provided with an internal thread.

[0046] The water outlet body 20 includes a water outlet seat 21 and a sealing cover 22 .

[0047] The water outlet seat 21 includes a shell 211 , a ring wall 212 and a plurality of protrusions 213 .

[0048] The shell 211 is cylindrical, and its outer wall is provided with an external thread, an inclined water channel 2111 and an annular limiting groove 2112, and its inner wall near its open end is provided with a step surface 2113 perpendicular to its axis, and its open end is provided with a block 2114 extending along its axis; wherein, the external thread is used to be screwed with the internal thread inside the accommodating cavity 12, and when screwed, the open end of the shell 211 faces the shoulder 13 of the step hole of the seat body 10, and the inclined water channel 2111 is perpendicular to the shell 211. The limiting groove 2112 is used for the installation of the first sealing ring 40. When the shell 211 and the seat body 10 are screwed into place, the first sealing ring 40 abuts against the inner wall of the accommodating chamber 12 and the groove wall of the limiting groove 2112 to achieve a sealed connection between the water outlet 20 and the seat body 10 to avoid water leakage in the accommodating chamber 12. The step surface 2113 is used for the abutment of the second sealing ring 50, and the clamping block 2114 is used to achieve clamping with the sealing cover 22.

[0049] The annular wall 212 coaxially penetrates and is integrally formed with the bottom of the shell 211 , and protrudes out of the outer wall of the bottom of the shell 211 , and the central hole thereof constitutes a water outlet 2121 of the water outlet body 20 .

[0050] The water outlet body 20 is further provided with a plurality of protrusions 213 around the water outlet 2121 in the water passage cavity, specifically, a plurality of protrusions 213 are provided around the ring wall 212 at the bottom of the shell 211, and an inclined water groove 214 is provided between adjacent protrusions 213. The inner side wall of the protrusion 213 is provided with an inclined surface 2131 inclined from top to bottom toward the water outlet 2121. The end surface of each protrusion 213 away from the water outlet 2121 forms a supporting surface 2132 perpendicular to the axis of the water outlet 2121. Among them, the inclined water groove 214 and the tangential water flow formed by the inclined water channel 2111 have the same rotation direction.

[0051] The sealing cover 22 is suitable for sealingly covering the open end of the housing 211. Specifically, the sealing cover 22 is a circular plate structure, and its side wall is provided with an annular flange 221. The outer diameter of the annular flange 221 is smaller than the inner diameter of the accommodating chamber 12. The annular flange 221 is provided with a water outlet 2211. The outer wall of the annular flange 221 is provided with a first groove 2212 adapted to the block 2114, and the inner wall of the annular flange 221 is provided with a second groove 2213; The cover 22 is also provided with a plug hole 222. When the sealing cover 22 is covered on the housing 211, part of the sealing cover 22 is matched and embedded in the inner cavity of the housing 211. One end of the annular flange 221 abuts against the end surface of the opening end of the housing 211, and the other end abuts against the shoulder 13 of the stepped hole of the seat body 10, so that the sealing cover 22 is held between the bottom of the accommodating cavity 12 and the water outlet seat 21, thereby limiting the axial movement of the sealing cover 22; and the block The second sealing ring 50 is sleeved on the outer periphery of the sealing cover 22 and abuts against the step surface 2113; when the sealing cover 22 and the housing 211 are snapped into place, the sealing cover 22 and the inner cavity of the housing 211 define a water passage cavity, the bottom of the housing 211 forms the bottom wall of the water passage cavity, the side wall of the housing 211 forms the side wall of the water passage cavity, and the annular flange 221 and the step surface 2113 are in contact with each other. It cooperates and presses against the second sealing ring 50 to prevent water leakage from the water passage chamber; when the sealing cover 22 is axially limited relative to the seat body 10, since the outer diameter of the annular flange 221 is smaller than the inner diameter of the accommodating chamber 12, the outer wall of the sealing cover 22 and the cavity wall of the accommodating chamber 12 form a water passage gap 100 connected to the inclined water channel 2111, and the water flowing in from the water inlet 11 can flow into the water passage gap 100 through the water port 2211, and then flow into the water passage chamber through the inclined water channel 2111.

[0052] The filter element 30 is mounted on the sealing cover 22 and is located between the water inlet 11 and the water outlet 2211. Specifically, the filter element 30 is a disc-shaped filter screen, which is axially extended downward and provided with a boss 31 that matches and plugs into the plug hole 222, and its side wall is protruding with an annular block 32 that is adapted to the second card groove 2213. When the filter element 30 is mounted on the sealing cover 22, the boss 31 is inserted into the plug hole 222, and the annular block 32 is axially engaged with the second card groove 2213, thereby limiting the axial displacement of the filter element 30, whereby the water flowing in from the water inlet 11 is filtered by the filter element 30 and flows to the water outlet 2211, which is healthier for users.

[0053] The rotating member 60 is located in the water passage cavity. It is provided with an impeller 65 corresponding to the inclined water channel 2111 and is suitable for rotating relative to the water outlet body 20 around the first axis. The first axis is also the axis of the housing 211. It extends into the water outlet 2121 and forms a water outlet gap with the water outlet 2121. The water passage cavity guides the water flow to the water outlet gap through the inclined water groove 214. The rotating member 60 is provided with a first water outlet hole 621 and a second water outlet hole 68 located between the first water outlet hole 621 and the water outlet gap along the first axis. The second water outlet hole 68 is arranged around the first water outlet hole 621. The first water outlet hole 621 and the second water outlet hole 68 are both connected to the water passage cavity at one end and discharge water at the other end. It should be understood that the number of the second water outlet hole 68 is at least one, and the case where the number of the second water outlet hole 68 is one will be described below.

[0054] Specifically, Figure 7 As shown, the rotating member 60 is provided with a rotating member body 61 , a central body 62 , a connecting body 63 , a rotating disk 64 , an abutting surface 641 , an impeller 65 , a plurality of convex tiles 66 and water pressure blocks 67 having the same number as the convex tiles 66 .

[0055] The rotating member body 61 extends into the water outlet 2121 and forms a first gap 200 with the water outlet 2121. The gap between the rotating member body 61 and the central body 62 forms a second water outlet 68. The first water outlet 621 is formed on the central body 62. The central body 62 is cylindrical with an opening upward, and the rotating member body 61 is tubular. The rotating member body 61 is arranged around the central body 62 and connected to the central body 62 through a connecting body 63.

[0056] Specifically, the inner cavity of the central body 62 forms a first water outlet hole 621, whose open end is connected to the water flow cavity, and the bottom of the cylinder is provided with at least one water outlet 6211, which can be spindle-shaped, or can be a plurality of column holes at different distances from the first axis, or a plurality of fan blade holes arranged circumferentially or a plurality of straight holes extending radially; wherein, the spindle-shaped water outlet can form a blade-shaped water outlet; the column holes can be located in the same radial direction, or can be distributed in different radial directions, which can form a water curtain-shaped water outlet; the fan blade holes or the straight holes can form a water curtain-shaped water outlet with a certain thickness.

[0057] like Figure 7-9As shown, the connecting body 63 includes at least two connecting ribs 631 arranged along the circumferential direction, and the two ends of each connecting rib 631 are respectively connected to the central body 62 and the rotating member body 61 at the water inlet end of the second water outlet hole 68. The connecting rib 631 is provided with a first pressurizing surface 6311 which is inclined backward from top to bottom relative to the rotation direction of the rotating member 60 at the water outlet end facing the second water outlet hole 68, that is, the first pressurizing surface 6311 is provided on the lower end surface of the connecting rib 631. In this embodiment, the connecting rib 631 is arc-shaped and convex relative to the rotation direction of the rotating member 60, so that the concave surface of the connecting rib 631 faces the rotation direction of the water flow in the second water outlet hole 68, and the arc-shaped connecting rib 631 increases the area of ​​the first pressurizing surface 6311, thereby enhancing the pressurizing effect on the water flow of the second water outlet hole 68.

[0058] The outer wall of the central body 62 facing the rotating member body 61 and the water inlet end facing the second water outlet hole 68 is provided with a second pressurizing surface 622 inclined outwardly relative to the water outlet direction. In this embodiment, the second pressurizing surface 622 extends in the circumferential direction, so that the contact area between the second pressurizing surface 622 and the water flow is larger, thereby further enhancing the pressurizing effect on the water flow of the second water outlet hole 68.

[0059] The inner wall of the rotating member body 61 facing the central body 62 and the water outlet end facing the second water outlet hole 68 is provided with a guide surface 611 inclined outwardly relative to the water outlet direction.

[0060] The rotating disk 64 is annular and is arranged around the outer wall of the rotating member body 61. The surface of the rotating disk 64 facing the protrusion 213 forms an abutting surface 641 opposite to the supporting surface 2132. The impeller 65 extends from the rotating disk 64 in a direction away from the water outlet 2121. The impeller 65 corresponds to the inclined water channel 2111. The rotating disk 64 is also provided with a plurality of water-passing grooves 642 located between the impeller 65 and the rotating member body 61. Each water-passing groove 642 is evenly arranged along the circumferential direction. It should be understood that when the abutting surface 641 of the rotating disk overlaps the supporting surface 2132 of the protrusion 213, a part of the rotating member body 61 is located on the inner side of each protrusion 213, and the other part extends into the water outlet 2121. When the abutting surface 641 and the supporting surface 2132 are in contact, there is a gap between the upper end surface of the impeller 65 and the bottom surface of the sealing cover 22, so that the rotating member 60 can still move upward relative to the water outlet seat.

[0061] Each convex tile 66 is convexly provided on the outer wall of the rotating member body 61, and each convex tile 66 is located under the rotating disk 64 and arranged along the circumferential direction. The water pressure blocks 67 are convexly provided on the convex tiles 66 one by one. The portion of the convex tile 66 located below the water pressure blocks 67 cooperates with the water outlet 2121 to form a second gap 300, such as Figure 4As shown, the second gap 300 is connected with the first gap 200 to form a water outlet gap. It should be understood that the first gap 200 is formed by the portion of the outer wall of the rotating member body 61 that is not covered by the convex tile 66 and the hole wall of the water outlet 2121. In this embodiment, the bottom end of the outer wall of the rotating member body 61 is inclined inward relative to the water outlet direction so that the spacing of the portion of the first gap 200 close to the water outlet end gradually increases along the water outlet direction. The intervals between adjacent convex tiles 66 are also connected to the water through grooves 642, that is, the convex tiles 66 form intervals equal to the number of water through grooves 642, and the intervals are connected to the water through grooves 642 one by one. The water flow through the water cavity can also flow from the water through grooves 642 to the intervals between adjacent convex tiles 66. The intervals between the convex tiles 66 can form a relatively thick water curtain part, and the flushing force is greater, so that the user can have a pulse-like massage experience when the water curtain rotates. A fourth pressurizing surface 661 is formed on the side wall of the convex tile 66 away from the water outlet direction of the inclined water trough 214 . The fourth pressurizing surface 661 is inclined relative to the supporting surface 2132 and presses the water flow toward the first gap 200 .

[0062] The water pressure block 67 corresponds to the inclined water tank 214, that is, corresponds to the protrusion 213. The water pressure block 67 is provided with a push surface 671 facing the water outlet direction of the inclined water tank 214. The push surface 671 is inclined relative to the support surface 2132 so that the water outlet of the inclined water tank 214 pushes the push surface 671, so that the abutment surface 641 is away from the support surface 2132. The water pressure block 67 is also provided with a third boosting surface 672 away from the water outlet direction of the inclined water tank 214. The third boosting surface 672 is inclined relative to the support surface 2132 and presses the water flow toward the water outlet gap. The water flow in the water outlet gap can rotate with the rotating member 60 and finally realize a rotating water outlet curtain. The water pressure block 67 is also provided with a connecting surface 673 connecting the push surface 671 and the third boosting surface 672. The connecting surface 673 is inclined relative to the support surface 2132. Among them, when the connecting surface 673 is opposite to the inclined surface of the protrusion 213 and a third gap 400 is generated between the inclined surface, the connecting surface 673 is inclined inward from top to bottom, the pushing surface 671 and the third boosting surface 672 are mirror-symmetrical, and the angle between the pushing surface 671 and the connecting surface 673 is an obtuse angle, the angle between the third boosting surface 672 and the connecting surface 673 is an obtuse angle, and the third boosting surface 672 is also parallel to the fourth boosting surface 661.

[0063] Here’s how it works:

[0064] The water flowing in from the water inlet 11 flows to the water outlet 2211 after being filtered by the filter element 30, flows into the water passing port 2211 through the water passing port 2211, flows into the water passing interval 100, and then flows into the water passing chamber through the inclined water channel 2111; the water flow guided by the inclined water channel 2111 impacts the impeller 65 to generate rotation, thereby driving the rotating member 60 to rotate. At the same time, the water flow in the water passing chamber firstly impacts the water pressure block 67 through the inclined water groove 214, thereby driving the rotating member 60 to rotate, secondly flows into the water outlet gap through the inclined water groove 214, thirdly directly flows into the first water outlet hole 621 of the central body 62 through the opening of the first water outlet hole 621, fourthly directly flows to the second water outlet hole 68 through the opening of the second water outlet hole 68, fifthly flows into the interval between the adjacent convex tiles 66 through the water groove 642 of the rotating disk 64, and sixthly flows into the water outlet gap through the third gap 400. The water flows out from the water outlet 6211 of the first water outlet hole 621, the water outlet end of the second water outlet hole 68 and the water outlet gap.

[0065] It can be seen from the above technical scheme that when the rotating part 60 rotates, the first water outlet 621 forms an inner circle of water outlet, and the second water outlet 68 and the water outlet gap both form an outer circle of water outlet, thereby forming a multi-circle water curtain effect, and the rotating part 60 of the present invention itself can form a rotating water curtain, so it is not easily affected by the eccentricity caused by the rotation speed of the rotating part 60. The water shape of the water curtain is stable, and a stable water curtain can be obtained without setting a complex structure. The structure is simple and ingenious; especially when the rotating part 60 is provided with multiple second water outlet holes 68, the rotating part 60 itself can form multiple circles of stable water curtains with good water outlet effect. More preferably, as mentioned above, the water outlet 6211 of the first water outlet 621 can be designed in different shapes, so that the water outlet shape of the water outlet device of the present application is diversified, thereby forming a multi-water shape water outlet effect.

[0066] When water flows through the water flow interval 100 and flows into the inclined water channel 2111, the water flow area of ​​the inclined water channel 2111 is small, the water flow velocity increases, and the water flow is pressurized; when water flows from the water flow cavity into the second water outlet 68, the first pressurization surface 6311 pressurizes the water flowing into the second water outlet 68 downward when the rotating member 60 rotates, and the water flow is subjected to an inclined downward pressure, which accelerates the water flow in the second water outlet 68; on the one hand, the second pressurization surface 622 causes the water flow to collide with the second pressurization surface 622, and the water flow velocity is accelerated and pressurized, and on the other hand, the water flow area of ​​the second water outlet 68 at the position corresponding to the second pressurization surface 622 is reduced, and the water flow velocity is accelerated and pressurized, that is, the first pressurization surface 6311 and the second pressurization surface 622 respectively pressurize the water flow in the second water outlet 68, so that the water flow out of the second water outlet 68 has a significant pressurization effect. The connecting rib 631 is arc-shaped and convex 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 easily dispersed.

[0067] When water flows from the water flow cavity into the inclined water trough 214, the water flow area of ​​the inclined water trough 214 is small, the water flow speed is accelerated, and the water flow pressure is increased; when the water flow impacts the push surface 671 and the connecting surface 673, the water flow is impacted, the water flow speed is accelerated, and the water flow pressure is increased; because the third pressure-increasing surface 672 and the fourth pressure-increasing surface 661 are both away from the water outlet direction of the inclined water trough 214, and are inclined relative to the support surface 2132 and press the water flow toward the water outlet gap, wherein the third pressure-increasing surface 672 can press the water flow toward the first gap 200 and the second gap 300, and the fourth pressure-increasing surface 661 can press the water flow toward the first gap 200, the water flow is subjected to an inclined downward pressure, the water flow is able to flow into the water outlet gap, and the pressure makes the water flow further accelerated in the water outlet gap, so as to realize the pressure-increasing of the water flow in the water outlet gap, and the third pressure-increasing surface 672 and the fourth pressure-increasing surface 661 jointly realize the water flow pressure increase, so that the water flow pressure increase effect in the water outlet gap is obvious.

[0068] Therefore, when the centrifugal force of the rotating part 60 remains unchanged, the water flow in the second water outlet hole 68 and the water outlet gap has a significant pressurizing effect, which is beneficial to controlling the opening angle of the rotating water outlet curtain relative to the water outlet direction and reducing the phenomenon of flying toward the periphery, thereby making the water flow of the rotating water outlet curtain more concentrated and full, and the flushing and massage effects on the user are also better.

[0069] Among them, the setting of the guide surface 611 allows the water flow in the second water outlet 68 to have enough space to be rectified into a water curtain shape, and the spacing of the water outlet gap close to the water outlet end gradually increases along the water outlet direction, so that the water flow in the water outlet gap has enough space to be rectified into a water curtain shape.

[0070] It can be seen from the above technical solution that since the tangential water flow formed by the inclined water trough 214 and the inclined water channel 2111 rotates in the same direction, the rotating member 60 is rotated by the impact of the impeller 65 by the water flow guided by the inclined water channel 2111 on the one hand, and by the impact of the water pressure block 67 by the water flow guided by the inclined water trough 214 on the other hand, so that the rotating member 60 can also rotate under the action of the low-pressure water flow.

[0071] Since the first pressurizing surface 6311 is inclined from top to bottom and backward relative to the rotation direction of the rotating member, the first pressurizing surface 6311 is also subject to an upward oblique resistance of the water flow, and the water flow pushes the rotating member 60 to float, thereby reducing the friction between the rotating member 60 and the water outlet body 20; the pushing surface 671 faces the water outlet direction of the inclined water trough 214 and is inclined relative to the supporting surface 2132. The water flow guided by the inclined water trough 214 can also act on the pushing surface 671, and the pushing surface 671 is subject to an upward oblique driving force, thereby pushing the abutting surface 641 away from the supporting surface 2132; since the connecting surface 673 is close to the pushing surface 671 and is inclined relative to the supporting surface 2132, when the water flows out of the inclined water trough 214, the water flow guided by the inclined water trough 214 can also act on the connecting surface 673, and the connecting surface 673 is subject to an upward oblique driving force, thereby pushing the abutting surface 641 away from the supporting surface 2132. More preferably, since the third pressurization surface 672 and the fourth pressurization surface 661 are both away from the water outlet direction of the inclined water tank 214, the third pressurization surface 672 and the fourth pressurization surface are both inclined relative to the support surface 2132, and the third pressurization surface 672 and the fourth pressurization surface 661 both press the water flow toward the water outlet gap, so when the rotating member 60 rotates, the third pressurization surface 672 and the fourth pressurization surface 661 are both subject to the resistance of the inclined upward water flow, and the water flow further pushes the rotating member 60 to float. Therefore, the arrangement of the first pressurization surface 6311, the pushing surface 671, the third pressurization surface 672, the fourth pressurization surface 661 and the connecting surface 673 enables the rotating member 60 to float under the action of the water flow, reducing the friction between the abutting surface 641 and the support surface 2132. More preferably, due to the presence of the third gap 400, the friction between the connecting surface 673 and the inclined surface 2131 of the protrusion 213 is further reduced, so that the friction force encountered by the rotating member 60 during rotation is small, so that the rotating member 60 can float up under high-pressure water flow and thus rotate rapidly. Under low-pressure water flow, the rotating member 60 can also rotate rapidly due to the dual effects of the inclined water channel 2111 and the inclined water trough 214, that is, the rotation of the rotating member 60 is not affected by the water pressure.
