Description

Technical Field

[0001] The present invention relates to the field of water outlet devices, and in particular to a water outlet device. Background Art

[0002] Existing water outlet devices typically feature a rotating element that rotates under the impact of the water flow. The water outlet performance is closely related to the water pressure. When the water pressure is high, the high-pressure water impacts the rotating element, causing it to spin rapidly. However, this also creates close contact between the rotating element and the water outlet device, resulting in high friction during rotation, which in turn affects the rotating element's speed and results in poor water outlet performance. When the water pressure is low, the rotating element rotates slowly, resulting in suboptimal water outlet performance. Summary of the Invention

[0013] Based on technical solutions one to eight, there is also a technical solution nine, which further includes a seat body, the seat body being provided with a water inlet and a accommodating chamber connected to the water inlet; the water outlet body comprising a water outlet seat and a sealing cover; the water outlet seat is fixed in the accommodating chamber to hold the sealing cover between the bottom of the accommodating chamber and the water outlet seat; the water outlet seat and the sealing cover cooperate to form the water flow chamber, and the water outlet hole, inclined water channel and protrusion are provided on the water outlet seat; a water flow interval connected to the inclined water channel is formed between the sealing cover and the cavity wall of the accommodating chamber, and the sealing cover is provided with a water outlet connected to the water inlet and the water flow interval.

[0014] Based on technical solution nine, technical solution ten is also provided. Technical solution ten further includes a filter element, which is installed on the sealing cover and located between the water inlet and the water outlet.

[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 the first 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 up under the high-pressure water flow and thus rotate rapidly, and under the low-pressure water flow, due to the inclined water channel and the inclined water channel, the rotating part can rotate rapidly. The dual-action rotating part of the trough can also rotate rapidly, that is, the rotation of the rotating part is not affected by the water pressure; at the same time, the water flow in the water outlet gap can rotate with the rotating part and finally realize a rotating water outlet curtain, which has a good massage effect; and when the water flows into the inclined water trough, the water flow area of ​​the inclined water trough is small, and 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 larger initial water outlet velocity along the water outlet direction, and the pressurization effect is obvious, so that the water flow of the rotating water outlet curtain is more concentrated and full, and the flushing effect and massage effect on the user are also better.

[0017] 2. In the second technical solution, the water pressure block is provided with a first pressurizing surface, which is away from the water outlet direction of the inclined water trough and inclined relative to the support surface. The first pressurizing surface also presses the water flow into the water outlet gap. Therefore, when the rotating part rotates, the first pressurizing surface is subjected to an upward oblique resistance of the water flow, and the water flow pushes the rotating part to float up, thereby helping to push the abutment surface away from the support surface; correspondingly, the water flow is subjected to an oblique downward pressure, and the water flow is able to flow into the water outlet gap, and the pressure makes the water flow further accelerate in the water outlet gap, thereby achieving water flow pressurization in the water outlet gap.

[0018] 3. In technical solution three, the water pressure block is also provided with a connecting surface, which connects the pushing surface and the first boosting surface. The connecting surface is inclined relative to the supporting surface and is suitable for being impacted by the water flow from the inclined water trough. Therefore, the connecting surface is subjected to an inclined upward thrust, so that the connecting surface can help push the abutting surface away from the supporting surface; the convex block is provided with an inclined surface corresponding to the connecting surface. Therefore, if there is a gap between the connecting surface and the inclined surface when the rotating part is not rotating, the flow rate increases when the water flows through the gap, thereby enhancing the flow rate of the water flow in the water outlet gap and significantly increasing the boosting effect; if there is no gap between the connecting surface and the inclined surface when the rotating part is not rotating, as the rotating part rotates, the rotating part floats up, and a gap is formed between the connecting surface and the inclined surface, which also increases the flow rate when the water flows through the gap, thereby enhancing the flow rate of the water flow in the water outlet gap and significantly increasing the boosting effect.

[0019] 4. In technical solution four, the rotating part is further provided with a main body, a turntable and a plurality of convex tiles, with a simple structure and reliable rotation function; the main body is provided with a water outlet cavity, and a part of the water flow in the water outlet cavity can flow through the water outlet cavity. Since the water outlet cavity is located on the inner side of the water outlet gap, the water outlet device has the effect of internal rotating water splashes and external rotating water curtains. The water outlet distribution volume increases geometrically compared with the distribution volume of non-rotating water outlet. The water outlet is delicate, the massage effect is good, and the user experience is good. At the same time, under the covering of the rotating water curtain of the outer ring, the water splashes of the water outlet cavity cannot splash out. The water outlet cavity has at least one water outlet, which can meet the different water outlet effects according to needs. The water pressure block is convexly arranged on the convex tile, with a simple and practical structure; the main body and the water outlet form a first gap, and the part of the convex tile located below the water pressure block cooperates with the water outlet to form a second gap. The first gap and the second gap are connected to form a water outlet gap. When water flows into the first gap from the inclined water groove, the water flow area is reduced and the water flow rate 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 angle of the rotating water outlet curtain relative to the water outlet direction and reduce the phenomenon of flying to the periphery, so that the water flow of the rotating water outlet curtain is more concentrated and full, and the flushing and massage effects on the user are also better; the turntable is also provided with a water passage located between the impeller and the main body. The water passage connects the gaps between adjacent convex tiles, that is, the water flow through the water cavity can also flow from the water passage to the gaps between adjacent convex tiles. The gaps between the convex tiles can form a relatively thick water curtain part, and the flushing force is greater, so that the user can bring a pulse-like massage experience when the water outlet curtain rotates.

[0020] 5. In technical solution five, a second pressurizing surface is provided on the side wall of the convex tile facing away from the water outlet direction of the inclined water trough. The second pressurizing surface is inclined relative to the support surface and presses the water flow toward the first gap. Therefore, when the rotating part rotates, the second pressurizing surface is subjected to an upward oblique resistance of the water flow, and the water flow pushes the rotating part to float up, which can also help push the abutting surface away from the support surface; accordingly, the water flow is subjected to an oblique downward pressure, and the water flow is able to flow into the first gap, and this pressure makes the water flow further accelerated in the water outlet gap, thereby achieving water flow pressurization in the water outlet gap, and the pressurization effect is obvious.

[0021] 6. In technical solution six, the setting of the first groove increases the area of ​​the hole wall of the water outlet, thereby increasing the water flow area, and the water flow hits the groove wall of the first groove, increasing the water flow resistance in the water outlet gap, thereby reducing the water flow velocity in the water outlet hole, that is, reducing the water flow velocity in the water outlet gap, thereby reducing the impact of centrifugal force and reducing the inertia of the rotating water outlet curtain thrown out in the direction of rotation under the action of centrifugal force, thereby reducing the angle of the rotating water outlet curtain relative to the water outlet direction and the phenomenon of flying toward the periphery.

[0022] 7. In technical solution seven, the setting of the second groove increases the area of ​​the side wall of the water flow chamber, thereby increasing the water flow area, and the water flow hits the groove wall of the second groove, increasing the water flow resistance in the water flow chamber, thereby reducing the water flow velocity in the water flow chamber, thereby avoiding the rotating part from rotating too fast, thereby further weakening the angle of the rotating water curtain relative to the water outlet direction and the phenomenon of flying toward the periphery.

[0023] 8. In technical solution eight, the setting of the speed reduction block increases the area of ​​the bottom wall of the water flow chamber, thereby increasing the water flow area, and the water flow hits the speed reduction block, increasing the water flow resistance in the water flow chamber, thereby further reducing the water flow velocity in the water flow chamber.

[0024] 9. In technical solution nine, the structural setting of the water outlet device is simple and easy to implement.

[0025] 10. In technical solution 10, the setting of the filter element can filter out impurities in the water, making it healthier for users. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0047] See also Figure 1-8 , Figure 1-8 A water outlet device is shown, including 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.

[0048] The seat body 10 is a tubular structure with a stepped hole provided therein, wherein the small hole of the stepped hole constitutes the water inlet 11, the large hole of the stepped hole constitutes the accommodating chamber 12, and the hole shoulder 13 of the stepped 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.

[0049] The water outlet body 20 includes a water outlet seat 21 and a sealing cover 22 .

[0050] The water outlet seat 21 includes a shell 211 , a ring wall 212 and a plurality of protrusions 213 .

[0051] 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. The 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. 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 axis of the housing 211 is inclined radially relative to the housing 211; the limiting groove 2112 is used for the installation of the first sealing ring 40. When the housing 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.

[0052] The annular wall 212 coaxially penetrates and is integrally formed with the bottom of the shell 211 . It protrudes from the outer wall of the bottom of the shell 211 , and its central hole constitutes a water outlet 2121 of the water outlet body 20 .

[0053] The outlet body 20 is further provided with a plurality of protrusions 213 surrounding the outlet hole 2121 within the water passage cavity. Specifically, the protrusions 213 are arranged on the bottom of the housing 211 around the annular wall 212, with inclined water channels 214 positioned between adjacent protrusions 213. The inner sidewalls of the protrusions 213 are provided with inclined surfaces 2131 that slope downwardly toward the outlet hole 2121. The end faces of each protrusion 213 facing away from the outlet hole 2121 form support surfaces 2132 perpendicular to the axis of the outlet hole 2121. The inclined water channels 214 align with the tangential water flow generated by the inclined water channel 2111 in the same direction.

[0054] The sealing cover 22 is adapted to be sealingly covered on 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 card groove 2212 adapted to the card block 2114, and the inner wall of the annular flange 221 is provided with a second card groove 2213. The cover 22 is also provided with an insertion 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 open 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 2114 is engaged with the first card groove 2212, limiting the rotation of the sealing cover 22. 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 shell 211 are engaged in place, the sealing cover 22 and the inner cavity of the shell 211 define a water cavity. The bottom of the shell 211 forms the bottom wall of the water cavity, and the side wall of the shell 211 forms the side wall of the water cavity. 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 flow chamber; when the sealing cover 22 is axially limited relative to the base 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 flow gap 100 connected to the inclined water channel 2111, and the water flowing in from the water inlet 11 can flow into the water flow gap 100 through the water port 2211, and then flow into the water flow chamber through the inclined water channel 2111.

[0055] 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. A boss 31 extending axially downwardly therefrom is provided, which mates with the insertion hole 222. An annular block 32 protruding from its sidewall mates with the second retaining groove 2213. When the filter element 30 is mounted on the sealing cover 22, the boss 31 is inserted into the insertion hole 222, and the annular block 32 engages with the second retaining groove 2213 along its axial direction, thereby limiting the axial displacement of the filter element 30. As a result, water flowing in from the water inlet 11 is filtered by the filter element 30 and flows to the water outlet 2211, making it healthier for users.

[0056] The rotating member 60 is located in the water passage cavity, and extends into the water outlet hole 2121 to form a water outlet gap between the water outlet hole 2121. The water passage cavity guides the water flow to the water outlet gap through the inclined water groove 214. Specifically, Figure 7 As shown, the rotating member 60 includes a body 61 , a rotating disk 62 , an abutting surface 621 , an impeller 63 , a plurality of convex tiles 64 and water pressure blocks 65 , the number of which is equal to the number of the convex tiles 64 .

[0057] The main body 61 extends into the water outlet hole 2121 and forms a first gap 200 with the water outlet hole 2121. The main body 61 is provided with a water outlet cavity 611. One end of the water outlet cavity 611 is open and connected to the water cavity, and the other end is provided with at least one water outlet 612; specifically, the main body 61 is cylindrical, and its inner cavity defines the water outlet cavity 611, and its open end is connected to the water cavity. The bottom of the cylinder is provided with at least one water outlet 612, and the water outlet 612 can be spindle-shaped, or it can be a number of column holes at different distances from the axis of the main body 61, or a number of fan blade holes arranged circumferentially or a number of straight holes extending radially; wherein, the spindle-shaped water outlet hole 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. Because part of the water flow in the water flow chamber can flow through the water outlet chamber 611, and the other part of the water flow can flow out of the first gap 200, the water flow out of the water outlet chamber 611 can rotate with the rotating member 60 to form a rotating water splash, and the water flow in the first gap 200 can rotate with the rotating member 60 and ultimately form a rotating water curtain. In addition, because the water outlet chamber 611 is located inside the first gap 200, the water outlet device has the effect of producing a rotating water splash in the inner circle and a rotating water curtain in the outer circle. The water distribution volume increases exponentially compared to the distribution volume of non-rotating water outlet, resulting in delicate water flow, excellent massage effect, and a good user experience. At the same time, under the protection of the rotating water curtain on the outer circle, the water flow out of the water outlet chamber 611 cannot splash outward. Under the protection of the rotating water curtain on the outer circle, the rotating water flow out of the water outlet chamber 611 cannot splash outward.

[0058] The turntable 62 is annular and is disposed around the outer wall of the body 61. The surface of the turntable 62 facing the protrusion 213 forms an abutment surface 621 opposite the support surface 2132. The impeller 63 extends from the turntable 62 in a direction away from the water outlet 2121. The impeller 63 corresponds to the inclined water channel 2111. The turntable 62 also has a plurality of water passages 622 located between the impeller 63 and the body 61. The water passages 622 are evenly distributed along the circumference. It should be understood that when the abutment surface 621 of the turntable overlaps the support surface 2132 of the protrusion 213, a portion of the body 61 is located inside each protrusion 213, while another portion extends into the water outlet 2121. When the abutment surface 621 and the support surface 2132 are in contact, a gap exists between the upper end surface of the impeller 63 and the bottom surface of the sealing cover 22, allowing the rotating member 60 to move upward relative to the water outlet seat 21.

[0059] Each convex tile 64 is protruded from the outer wall of the body 61. Each convex tile 64 is located below the turntable 62 and arranged along the circumferential direction. The water pressure blocks 65 are protruded on the convex tiles 64 in a one-to-one correspondence. The portion of the convex tile 64 located below the water pressure blocks 65 cooperates with the water outlet holes 2121 to form a second gap 300. Figure 6As shown, the second gap 300 is connected to the first gap 200 to form a water outlet gap. The spacing of the first water outlet gap 200 located below the convex tile 64 decreases along the water outlet direction. It should be understood that the first gap 200 is formed by the portion of the outer wall of the body 61 that is not covered by the convex tile and the hole wall of the water outlet hole 2121. The gaps between adjacent convex tiles 64 are also connected to the water grooves 622, that is, the gaps between each convex tile 64 are equal to the number of water grooves 622, and the gaps are connected to the water grooves 622 one by one. The water flow through the water cavity can also flow from the water grooves 622 to the gaps between adjacent convex tiles 64. The gaps between the convex tiles 64 can form a relatively thick water curtain part, which has a greater flushing force, thereby being able to provide the user with a pulse-like massage experience when the water curtain rotates. A second pressurizing surface 641 is formed on the side wall of the convex tile 64 facing away from the water outlet direction of the inclined water trough 214 . The second pressurizing surface 641 is inclined relative to the supporting surface 2132 and presses the water flow toward the first gap 200 .

[0060] The water pressure block 65 corresponds to the inclined water trough 214, that is, to the protrusion 213. The water pressure block 65 is provided with a pushing surface 651 facing the water outlet direction of the inclined water trough 214. The pushing surface 651 is inclined relative to the support surface 2132 so that the water outlet of the inclined water trough 214 pushes the pushing surface 651, thereby moving the abutting surface 621 away from the support surface 2132. The water pressure block 65 also has a first pressurizing surface 652 facing away from the water outlet direction of the inclined water trough 214. The first pressurizing surface 652 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 ultimately achieve a rotating water curtain. The water pressure block 65 also has a connecting surface 653 connecting the pushing surface 651 and the first pressurizing surface 652. The connecting surface 653 is inclined relative to the support surface 2132. Among them, when the connecting surface 653 is opposite to the inclined surface 2131 of the protrusion 213 and a third gap 400 is generated between the connecting surface 653 and the inclined surface 2131, the connecting surface 653 is inclined inward from top to bottom, the pushing surface 651 and the first boosting surface 652 are mirror-symmetrical, and the angle between the pushing surface 651 and the connecting surface 653 is an obtuse angle, the angle between the first boosting surface 652 and the connecting surface 653 is an obtuse angle, and the first boosting surface 652 is also parallel to the second boosting surface 641.

[0061] Here’s how it works:

[0062] The water flowing in from the water inlet 11 is filtered by the filter element 30 and flows to the water outlet 2211, flows into the water gap 100 through the water outlet 2211, and then flows into the water chamber through the inclined water channel 2111; the water flow guided by the inclined water channel 2111 impacts the impeller 63 to cause rotation, thereby driving the rotating member 60 to rotate. At the same time, the water flow in the water chamber firstly impacts the water pressure block 65 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 flows directly into the water outlet chamber 611 of the main body 61 through the opening of the water outlet chamber 611, fourthly flows into the gap between the adjacent convex tiles 64 through the water groove 622 of the turntable 62, and fifthly flows into the water outlet gap through the third gap 400, and the water flows out from the water outlet 612 of the water outlet chamber 611 and the water outlet gap.

[0063] 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 water flow guided by the inclined water channel 2111 impacting the impeller 63 on the one hand, and by the water flow guided by the inclined water trough 214 impacting the water pressure block 65 on the other hand, so that the rotating member 60 can also rotate under the action of the low-pressure water flow.

[0064] Since the pushing surface 651 faces the water outlet direction of the inclined water trough 214 and is inclined relative to the support surface 2132, the water flow guided by the inclined water trough 214 can also act on the pushing surface 651, and the pushing surface 651 is subjected to an inclined upward pushing force, thereby pushing the abutting surface 621 away from the support surface 2132; since the connecting surface 653 is close to the pushing surface 651 and is inclined relative to the support 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 653, and the connecting surface 653 is subjected to an inclined upward pushing force, thereby pushing the abutting surface 621 away from the support surface 2132. More preferably, because the first and second pressurizing surfaces 652 and 641 face away from the water outlet direction of the inclined water trough 214 and are inclined relative to the support surface 2132, the first and second pressurizing surfaces 652 and 641 both pressurize the water flow toward the water outlet gap. Therefore, when the rotating member 60 rotates, the first and second pressurizing surfaces 652 and 641 are both subject to resistance from the upwardly inclined water flow, which further propels the rotating member 60 upward. Therefore, the arrangement of the pushing surface 651, the first and second pressurizing surfaces 652 and 641, and the connecting surface 653 allows the rotating member 60 to float upward under the action of the water flow, reducing the friction between the abutting surface 621 and the support surface 2132. More preferably, due to the presence of the third gap 400, the friction between the connecting surface 653 and the inclined surface 2131 of the protrusion 213 is further reduced, so 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 action of the inclined water channel 2111 and the inclined water groove 214, that is, the rotation of the rotating member 60 is not affected by the water pressure.

[0065] When water flows through the water gap 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 at the first level; when water flows from the water cavity into the inclined water trough 214, the water flow area of ​​the inclined water trough 214 is small, the water flow velocity is accelerated, and the water flow is pressurized at the second level; when the water flow impacts the pushing surface 651 and the connecting surface 653, the water flow is impacted, the water flow velocity is accelerated, and the water flow is pressurized at the third level; because the first pressurizing surface 652 and the second pressurizing surface 641 are both away from the water outlet direction of the inclined water trough 214 and are inclined relative to the support surface 2132 and pressurize the water flow toward the water outlet gap, wherein, The first pressurizing surface 652 can press the water flow toward the first water outlet gap 200 and the second water outlet gap 300, and the second pressurizing surface 641 can press the water flow toward the first water outlet gap 200. The water flow is subjected to a downward pressure, so that the water flow can flow into the water outlet gap, and the pressure makes the water flow further accelerate in the water outlet gap, thereby pressurizing the water flow in the water outlet gap. The first pressurizing surface 652 and the second pressurizing surface 641 jointly realize the four-level water flow pressurization; the spacing of the first water outlet gap 200 located below the convex tile 64 decreases along the water outlet direction, the water flow velocity gradually accelerates, and the water flow is pressurized at the fifth level.

[0066] Therefore, when the centrifugal force of the rotating part 60 remains unchanged, the pressurization effect of the water flow is obviously beneficial to controlling the angle of the rotating water 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 curtain more concentrated and full, and the flushing and massage effects on the user are also better.

[0067] In a specific embodiment, a speed reduction mechanism is also provided to prevent the rotating member 60 from rotating too fast. Specifically, the wall of the water outlet hole 2121 is provided with a plurality of circumferentially arranged first grooves 2122 at positions corresponding to the convex tiles 64. The first grooves 2122 open into the water passage cavity and, in this embodiment, extend in the direction of water discharge. The sidewall of the water passage cavity is provided with a plurality of circumferentially arranged second grooves 2115, which extend in the direction of water discharge from the water outlet hole 2121. The bottom wall of the water passage cavity is also provided with a plurality of speed reduction blocks 2116 at positions corresponding to the protrusions 213. The speed reduction blocks 2116 extend radially from the protrusions 213 toward the sidewalls.

[0068] The setting of the first groove 2122 increases the area of ​​the hole wall of the water outlet hole 2121, thereby increasing the water flow area, and the water flow hits the groove wall of the first groove 2122, increasing the water flow resistance in the water outlet gap, thereby reducing the water flow velocity in the water outlet hole 2121, that is, reducing the water flow velocity in the water outlet gap, thereby reducing the influence of the centrifugal force and the inertia of the rotating water curtain thrown out in the rotation direction under the action of the centrifugal force, thereby reducing the angle of the rotating water curtain relative to the water outlet direction and the phenomenon of flying out to the periphery; the second groove 21 The setting of 15 increases the area of ​​the side wall of the water flow chamber, and the water flow hits the groove wall of the second groove 2115, increasing the water flow resistance in the water flow chamber, thereby reducing the water flow velocity in the water flow chamber; the setting of the deceleration block 2116 increases the area of ​​the bottom wall of the water flow chamber, thereby increasing the water flow area, and the water flow hits the deceleration block 2116, increasing the water flow resistance in the water flow chamber, thereby reducing the water flow velocity in the water flow chamber, thereby avoiding the rotating part 60 from rotating too fast, thereby weakening the angle of the rotating water curtain relative to the water outlet direction and the phenomenon of flying toward the periphery.

[0069] It can be seen that in this embodiment, the initial water velocity of the water flow in the water outlet gap is gradually enhanced to achieve the purpose of offsetting the influence of centrifugal force on the rotating water outlet curtain, and a deceleration structure is set to weaken the influence of centrifugal force, which can also achieve the purpose of reducing the opening angle of the rotating water outlet curtain, so that the opening angle of the rotating water outlet curtain relative to the water outlet direction can be controlled to achieve a good anti-splashing effect.
