When the inner shell 2 is inserted into the outer shell 1, the cavity of the inner shell 2 and the lower cavity of the outer shell 1 form a water outlet cavity 23, and the annular insertion block 211 is inserted into the annular groove 13; in the embodiment, the annular insertion block 211 and the annular groove 13 are fixed by welding to fix the connection between the inner shell 2 and the outer shell 1; in other embodiments, the outer shell 1 and the inner shell 2 can be fixed by other connection methods commonly used in the art, such as threaded connection.

[0052] Referring to Figure 5 , 6 , 13, Figure 5 , 6 Figure 3 shows the first perspective view and the second perspective view of the water outlet member 3 in the embodiment, Figure 13 Figure 4 is a longitudinal sectional view of the water outlet device. As shown, the water outlet member 3 comprises a main body 31 and a second water outlet part 32; the main body 31 is a hollow cylindrical body in the shape of an inverted convex letter with open ends, and the inner wall of the upper cavity of the main body 31 is provided with internal teeth in the circumferential direction, forming a second gear 311; the second gear 311 is suitable for cooperating with the transmission gear 7, and the number of teeth of the second gear 311 is greater than the number of teeth of the transmission gear 7, so as to reduce the rotation speed of the water outlet member 3; the second water outlet part 32 extends from the bottom wall of the lower cavity of the main body 31 in a direction away from the main body 31 in the first direction, and the second water outlet part 32 is provided with a water outlet opening 321 communicating with the cavity of the main body 31; in the embodiment, the water outlet opening 321 comprises two first water outlet holes 3211 and two second water outlet holes 3212 arranged staggered in the circumferential direction, and the water outlet angle of the first water outlet holes 3211 is different from the water outlet angle of the second water outlet holes 3212.

[0053] The water outlet 3 is adapted to be installed in the water outlet cavity 23 and rotate relative to the body around the rotation axis extending in the first direction. Specifically, in the embodiment, the main body 31 of the water outlet 3 is accommodated in the water outlet cavity 23, and two first intervals 33 are formed between the side wall of the main body 31 and the side wall of the water outlet cavity 23 along a direction perpendicular to the first direction, which are respectively an upper first interval and a lower first interval. In the embodiment, the side wall of the main body 31 is staggered with the protrusions 312 in the circumferential direction to reduce the contact surface between the side wall of the main body 31 and the side wall of the water outlet cavity 23 when the water outlet 3 rotates, thereby reducing the friction between the water outlet 3 and the inner shell 2. In the embodiment, the bottom wall of the main body 31 and the bottom wall of the water outlet cavity 23 form two second intervals 34 along the first direction, which are respectively an upper second interval and a lower second interval. The two first intervals 33 and the two second intervals 34 are communicated. The second water outlet part 32 is adapted to be inserted into the fitting hole 221 and cover the lower second interval along the first direction. The sealing element 8 is adapted to be placed on the support surface 222 and cover the second water outlet part 32. When the second water outlet part 32 is inserted into the fitting hole 221, the sealing element 8 seals the second water outlet part 32 and the first water outlet part 22 to seal the gap between the second water outlet part 32 and the fitting hole 221, thereby preventing water from leaking from the lower second interval, so that the first interval 33 and the second interval 34 maintain stable water pressure when filled with water, thereby providing stable buoyancy and lubrication for the water outlet 3. In the embodiment, the sealing element 8 is a V-shaped sealing ring.

[0054] Referring to Figure 7 、 8 , the first perspective view and the second perspective view of the water distribution element 4 in the embodiment are shown. As shown in the figure, the water distribution element 4 is a disc type, and a plurality of water passing holes 41 are uniformly arranged along the outer peripheral wall of the water distribution element 4. The water passing holes 41 are adapted to pass through the partition block 213 to enable the water distribution element 4 to be seated on the first step surface 212 and cover the cavity of the main body 31. The water passing holes 41 communicate the water outlet cavity 23 and the upper first interval. A through hole 42 is arranged at the center of the water distribution element 4 to be adapted to pass through the rotating element 5 to connect the transmission gear 7. The inner wall of the through hole 42 forms two symmetrical arc-shaped shaft sleeves 44 along the first direction of the water distribution element 4, which play a guiding and positioning role. A positioning hole 43 is arranged between the through hole 42 and the water passing hole 41 in the radial direction of the water distribution element 4 to position and install the transmission gear 7, so that the transmission gear 7 cooperates with the second gear 311. The inner wall of the positioning hole 43 extends along the first direction to form a convex ring 431 to reduce the contact surface between the transmission gear 7 and the lower surface of the water distribution element 4 when the transmission gear 7 rotates. A plurality of convex strips 45 are staggered around the through hole 42 on the upper surface of the water distribution element 4, and gaps are formed between the convex strips 45 to enable water to flow into the through hole. In the embodiment, the convex strips 45 are semi-cylindrical. A plurality of semi-spherical protrusions 46 are uniformly arranged in the circumferential direction on the upper surface of the water distribution element 4. The convex strips 45 and the protrusions 46 are adapted to be abutted by the rotating element 5 to support the rotating element 5 and reduce the friction between the rotating element 5 and the water distribution element 4 when the rotating element 5 rotates.

[0055] Referring toFigure 9 、 10 , the first perspective view and the second perspective view of the rotating member 5 in the embodiment are shown. As shown in the figure, the rotating member 5 in the embodiment is a vane wheel, which comprises a spoke 51 and a shaft 52. The spoke 51 is in the shape of a wheel, and the spoke 51 is provided with a concave hole 511. The lower surface of the spoke 51 is adapted to abut against the convex strip 45 and the convex 46. The shaft 52 is provided with a shaft hole 521 which is coaxial with the concave hole 511. The shaft hole 521 is in communication with the concave hole 511 and the water outlet 321. The inner diameter of the shaft hole 521 is smaller than that of the concave hole 511. The outer wall of the shaft 52 is provided with external teeth along the circumference, forming a first gear 522. The shaft 52 is adapted to pass through the through hole 42 so that the first gear 522 cooperates with the transmission gear 7. When the vane wheel rotates, the first gear 522 drives the transmission gear 7, which drives the second gear 311, so as to rotate the water outlet member 3.

[0056] Referring to Figure 11 、 12 , the first perspective view and the second perspective view of the face cover 6 in the embodiment are shown. As shown in the figure, the face cover 6 is in the shape of a flat cylinder. The face cover 6 is provided with a plurality of water inlet holes 61 along the circumference. In the embodiment, there are two water inlet holes 61, which are square holes inclined downward along the first direction, so as to make the water flow impact the vane wheel obliquely, and the water flow displacement is larger, the terminal velocity is greater, and the impact on the vane wheel is more powerful, so as to make the vane wheel rotate more easily. In other embodiments, the water inlet holes 61 can also be circular holes or holes of other shapes along the first direction. In the embodiment, the upper surface of the face cover 6 is provided with a support block 62 along the circumference, which is adjacent to the water inlet hole 61. The support block 62 is adapted to abut against the water passing wall 11 and make the water inlet hole 111 communicate with the water inlet hole 61. In the embodiment, there are four water inlet holes 111 along the circumference of the water passing wall 11. The cross section of each water inlet hole 111 is larger than that of each water inlet hole 61, so as to make the water flow speed greatly increase when passing through the face cover 6 due to the greatly reduced cross section of the flow channel, and then flow into the water outlet cavity 23 to impact the vane wheel and make it rotate. The face cover 6 plays a role of acceleration, so as to make the vane wheel rotate even when the water flow speed at the water inlet hole 111 is small or the water pressure is small, and drive the water outlet member 3 to rotate to overcome the friction between the water outlet member 3 and the sealing member 8. The lower end of the face cover 6 is provided with a second step surface 63, which is adapted to abut against the upper end of the inner shell 2, so as to seal the water outlet cavity 23. The lower surface of the face cover 6 is provided with a circular shaft 64 extending along the first direction, which is adapted to extend into the concave hole 511 and have a gap with the bottom wall of the concave hole 511, so as to make the rotating member 5 rotate more smoothly around the rotation axis.

[0057] Referring to Figure 13As shown in the figure, the sealing member 8 is placed on the supporting surface 222 of the first water outlet part 22, and the second water outlet part 32 of the water outlet member 3 is inserted into the matching hole 221 of the first water outlet part 22, so that the inner end of the sealing member 8 is sleeved on the second water outlet part 32, and the outer end of the sealing member 8 is in interference fit with the inner wall of the first water outlet part 22, thereby realizing the sealed fit between the first water outlet part 22 and the second water outlet part 32. Then, the transmission gear 7 is assembled into the main body 31 so that the transmission gear 7 is matched with the second gear 311, and the positioning hole 43 of the water distribution member 4 is sleeved on the shaft part 52 of the transmission gear 7. Then, the shaft part 52 of the impeller is inserted through the through hole 42, so that the first gear 522 is extended out of the through hole 42 and matched with the transmission gear 7, and the spoke part 51 of the impeller abuts against the convex strip 45 and the convex 46. Then, the circular shaft 64 of the cover 6 is inserted into the recess hole 511, so that the second step surface 63 is matched with the upper end of the inner shell 2. Finally, the outer shell 1 is sleeved on the inner shell 2, so that the annular insertion block 211 is inserted into the annular groove 13, the water passing wall 11 abuts against the supporting block 62, and the annular insertion block 211 and the annular groove 13 are welded together.

[0058] Referring to Figure 14 As shown in the figure, when water is used, the water flows from the water inlet channel 12 to the cover 6 through the water inlet 111. When the water flows through the cover 6, the number of the water inlet holes 61 is less than the number of the water inlets 111, and the cross-sectional area of a single water inlet hole 61 is less than the cross-sectional area of a single water inlet 111, so that the flow rate of the water increases greatly when the water flow leaves the water inlet hole 61 and enters the water outlet cavity 23. Since the water inlet holes 61 are arranged circumferentially along the cover 6, and the water passing holes 41 are arranged along the outer periphery of the water distribution member 4, when the water flow enters the water outlet cavity 23, part of the water flow impacts the impeller and drives the impeller to rotate, and part of the water flow enters the water passing holes 41 and flows into the first interval 33 and then the second interval 34. Moreover, due to the centrifugal force generated when the impeller rotates, a considerable part of the water also enters the first interval 33 and the second interval 34 through the water passing holes 41. Since the sealing member 8 realizes the sealed fit between the first water outlet part 22 and the second water outlet part 32, the water entering the first interval 33 and the second interval 34 is prevented from leaking and is accumulated until it is filled. Then, the water entering the water outlet cavity 23 directly flows to the water outlet 321 through the through hole 42 and flows out through the water outlet holes. The water outlet holes include the first water outlet holes 3211 and the second water outlet holes 3212 which have different water outlet angles. With the rotation of the water outlet member 3, multiple circles of water curtains can be formed, and the water curtains can also intersect with each other, thereby achieving a good perspective effect.

[0059] Compared with the prior art, the embodiment has the following beneficial effects:

[0060] In the embodiment, the water outlet device comprises a body, a water outlet element 3 and a water distribution element 4; the body comprises an outer shell 1 and an inner shell 2, the outer shell 1 and the inner shell 2 are fixedly sleeved to form a water outlet cavity 23, the inner shell 2 comprises a first water outlet part 22, the first water outlet part 22 is provided with a matching hole 221 along a first direction; the water outlet element 3 is adapted to rotate relative to the body around a rotation axis extending along the first direction, the water outlet element 3 comprises a main body 31 and a second water outlet part 32, the second water outlet part 32 is sealingly matched with the first water outlet part 22 and is inserted into the matching hole 221; the second water outlet part 32 is provided with a water outlet opening 321 communicating with the water outlet cavity 23 along the first direction, a first interval 33 is formed between a side wall of the main body 31 and a side wall of the water outlet cavity 23 perpendicularly to the first direction, a second interval 34 is formed between a bottom wall of the main body 31 and a bottom wall of the water outlet cavity 23 along the first direction, and the first interval 33 and the second interval 34 are communicated; the water distribution element 4 covers a cavity of the main body 31, the water distribution element 4 is provided with a through hole 42 in the center and a water passing hole 41 along the outer periphery; the through hole 42 communicates with the water outlet opening 321, and the water passing hole 41 communicates with the first interval 33; thus, when water flows into the water outlet cavity 23 and flows through the water distribution element 4, the water will flow into the first interval 33 and the second interval 34 through the water passing hole 41; because the second water outlet part 32 is sealingly matched with the first water outlet part 22, the water flow keeps a pressure state after filling the first interval 33 and the second interval 34, and drives the water flow to flow out from the water outlet opening 321 through the through hole 42; when the water outlet element 3 rotates relative to the body around the rotation axis extending along the first direction, the water in the second interval 34 reduces the friction of the water outlet element 3 relative to the body, and the water in the first interval 33 and the second interval 34 has a certain lubricating effect when the water outlet element 3 rotates, which also reduces the rotating friction of the water outlet element 3; compared with the prior art, because the first interval 33 and the second interval 34 are always filled with water, the water flow of the water outlet element 3 is basically unchanged, so that the effect of reducing the friction of the water outlet element 3 relative to the main body 31 is more stable, reliable and predictable, and the loss of the water outlet element 3 is reduced.

[0061] In the embodiment, the side wall of the main body 31 is provided with a protrusion 312 to reduce the possible friction contact surface between the water outlet element 3 and the side wall of the water outlet cavity 23 when the water outlet element 3 rotates, thereby reducing the friction between the water outlet element 3 and the side wall of the water outlet cavity 23 when the water outlet element 3 rotates.

[0062] In the embodiment, when the water outlet opening 321 comprises a plurality of water outlet holes, the jet angles of at least two water outlet holes are different; because a water curtain is formed by the water flow from each water outlet hole when the water outlet element 3 rotates, and the jet angles of the water outlet holes are different, a plurality of water curtains are formed, and the plurality of water curtains can also intersect with each other, the visual angle effect is good, and the massage effect is increased.

[0063] In the embodiment, the water-dividing member 4 is provided with the through hole 42 and the water-passing hole 41 to divide the water flow to the first space 33 and the water outlet 321. The water-passing hole 41 is arranged along the outer periphery, which is more conducive to the rotation of the water outlet member 3 relative to the body, and the water flow enters the first space 33 and the second space 34 under the action of centrifugal force along the water-passing hole 41, thereby facilitating the water filling of the first space 33 and the second space 34.

[0064] In the embodiment, the convex strip 45 and the arc-shaped convex 46 support the rotating member 5, prevent it from tilting, and reduce the rotating friction. The staggered arrangement ensures that the water flows into the through hole 42 and the water-passing hole 41.

[0065] In the embodiment, the drive assembly includes an impeller and a speed reduction mechanism, which reduces the speed of the water flow out of the water outlet 321 while driving the water outlet member 3 to rotate, thereby reducing the water outlet pressure and improving user comfort.

[0066] In the embodiment, the speed reduction is achieved by the cooperation of the impeller, the transmission gear 7, and the inner gear of the water outlet member 3, which runs stably, has low noise, and has a long service life.

[0067] In the embodiment, the cross-sectional area of the water inlet hole 61 is smaller than that of the water inlet 111, so that the water flow speed increases when flowing through the water inlet hole 61, the water pressure increases, and the rotating member 5 is accelerated to rotate or the water flow is accelerated to flow into the first space 33 when entering the water outlet cavity 23.

[0068] In the embodiment, the circular shaft hole 521 at the end of the face cover 6 opposite to the rotating member 5 cooperates to make the rotating member 5 rotate more stably around its rotation axis.
