[0009] The rotating member drives the switching member to move relative to the body around the first axis, so that the outer teeth mesh with the inner teeth to make the switching member rotate relative to the rotating member around the second axis, thereby switching the water outlet state of the water outlet.

[0010] Based on the first technical solution, in the second technical solution, the first number of teeth is N, and the second number of teeth is N-1.

[0014] According to the first technical solution, in a fifth technical solution, the switching piece further comprises a water passing part fixedly connected with the outer teeth, the water passing part is attached to the plane where the water outlet is located, and the switching piece is further provided with a first water passing hole, the first water passing hole is communicated with the water passing cavity and the water outlet.

[0015] According to the fifth technical solution, in a sixth technical solution, the water passing part extends circumferentially relative to the outer teeth; the body comprises a tooth part, the inner teeth are arranged on the tooth part, the tooth part is sleeved on the outer teeth and abuts against the water passing part to make the water passing part attached to the plane where the water outlet is located and prevent the inner teeth and the outer teeth from disengaging.

[0016] According to the first technical solution, in a seventh technical solution, the water outlet comprises a first water outlet and a second water outlet.

[0017] The body is further provided with a first cavity, a second cavity and a plurality of water outlets and second water passing holes.

[0018] The first cavity is communicated with the first water outlet and each of the water outlets; the second cavity is communicated with the second water outlet, each of the second water passing holes is communicated with the first cavity and the second cavity; the second water passing hole is correspondingly arranged with the water outlet, and the water outlet direction of the second water passing hole is towards the hole wall corresponding to the water outlet.

[0019] According to the seventh technical solution, in an eighth technical solution, the first cavity is provided with a first cavity wall, and each of the water outlets is arranged on the first cavity wall.

[0020] The second cavity wall is arranged between the first cavity and the second cavity, and the second water passing hole is arranged on the second cavity wall.

[0021] The hole diameter of the water outlet gradually decreases along the water outlet direction.

[0022] According to the eighth technical solution, in a ninth technical solution, a first protruding column is protruded on the surface of the first cavity wall towards the second cavity wall, and a second protruding column is protruded on the surface of the first cavity wall away from the second cavity wall.

[0023] The first convex column and the second convex column correspond to each other;

[0024] The water outlet hole penetrates the first convex column and the second convex column.

[0025] Based on the seventh technical solution, in the tenth technical solution, each water outlet hole corresponds to a plurality of second water passing holes, and the plurality of second water passing holes are obliquely arranged and evenly distributed around the axis of the water outlet hole corresponding thereto.

[0026] From the above description of the present application, the present application has the following beneficial effects relative to the prior art:

[0027] 1. In the first technical solution, the output end of the rotating member is parallel to the first axis, and the switching member and the output end of the rotating member are connected. When the rotating member rotates around the first axis, it can drive the switching member to move around the first axis relative to the body and the outer teeth of the switching member mesh with the inner teeth of the body. The output end of the switching member and the rotating member is a rotating connection, that is, the switching member allows rotation relative to the rotating member. When the rotating member rotates around the first axis to drive the switching member to move around the first axis relative to the body, the meshing state of the outer teeth and the inner teeth will not cause the switching member to be stuck, but will make the switching member rotate relative to the rotating member with the second axis as the rotation axis. The teeth on the outer teeth and the inner teeth are disengaged. After the switching member rotates one tooth, the new teeth and the inner teeth re-engage. During the meshing process, since the second number of teeth is less than the first number of teeth, when the rotating member drives the switching member to rotate, each tooth of the switching member needs to mesh with each tooth of the inner teeth once. The time for the switching member to rotate one circle will be greater than the time for the rotating member to rotate one circle. The speed reduction ratio is 1 / first tooth number, so the function of speed reduction is realized.

[0028] When the rotating member rotates around the first axis to drive the switching member to move around the first axis relative to the body, the position of the switching member relative to the body changes. When the switching member rotates due to meshing, its position relative to the body changes due to rotation. Both factors will cause the communication state of the water passing cavity and the water outlet to change, thereby switching the water outlet state. Therefore, the movement of the switching member around the first axis relative to the body and the rotation of the switching member around the second axis can both achieve the switching of the water outlet state. Among them, the rotation of the switching member plays a dominant role in the process of switching the water outlet state. The change of the water outlet state can refer to the change of opening and closing or the change of water quantity, that is, the change of opening and closing caused by the opening or complete shielding of the water outlet by the switching member, and the change of water quantity caused by always opening the water outlet and changing the shielding area to change the area of the water outlet.

[0029] 2. In the second technical solution, each tooth of the outer teeth needs to mesh with each tooth of the inner teeth once. Therefore, when the rotating member rotates N times, the outer teeth rotate 1 time, and the speed reduction ratio is 1 / N, which can reduce the speed by N times and prevent the meshing from being poor when the difference between the number of teeth is too large.

[0030] 3. The third technical solution automatically changes the water outlet state by driving the impeller through water power, thereby saving energy.

[0031] 4. The fourth technical solution tilts the water hole and points to the impeller to guide the rotation of the impeller, thereby realizing the rotation of the impeller. Compared with the direct impact of the impeller by the water inlet, since the number of water inlets is limited compared with the water hole, the impact force is preferential, and the tilt angle is not convenient to set, so the impeller is more easily driven by the water hole, and it is more convenient to process.

[0032] 5. The fifth technical solution provides a first water hole in the water passing part, and the first water hole is in communication with the water passing cavity and the water outlet, thereby realizing water passing, preventing the problem of reducing the strength of the outer tooth and easily damaging when the first water hole is directly opened on the outer tooth, and if the first water hole is opened on the outer tooth, since the number of teeth of the outer tooth needs to be kept normal and uninterrupted to make the outer tooth and the inner tooth mesh smoothly, the first water hole cannot be set at the edge of the outer tooth, but only at the position close to the middle, and then the position of the water outlet needs to directly correspond to the position of the first water hole, and the position of the water outlet is not flexible enough.

[0033] 6. The sixth technical solution sets the tooth piece in the outer tooth and abuts against the water passing part to make the water passing part fit the plane where the water outlet is located and prevent the inner tooth and the outer tooth from disengaging, thereby ensuring smooth working state, preventing the inner tooth and the outer tooth from disengaging due to shaking during movement, causing damage, making the water passing part not fit the plane where the water outlet is located, causing the water outlet state not to switch, requiring the user to disassemble and maintain, increasing the cost and possibly reducing the service life.

[0034] 7. The seventh technical solution sets a first water outlet and a second water outlet in the body through a first cavity and a second cavity in communication, respectively, and adjusts the proportion of water entering the first cavity and the second cavity through a switching piece. Since the second water hole is in communication with the first cavity and the second cavity, the water in the second cavity can enter the first cavity through the second water hole. The water outlet direction of the second water hole is towards the hole wall of the corresponding water outlet, so the water outlet of the second water hole can hit the hole wall of the water outlet to scatter and form granular water. Since the first cavity is in communication with the water outlet, the water in the first cavity and the second cavity can flow out of the water outlet at the same time.

[0035] 8. The eighth technical solution gradually reduces the hole diameter of the water outlet along the water outlet direction, so that the hole wall of the water outlet is a conical surface, and the effect of scattering water is better.

[0036] 9. The ninth technical solution sets a first protruding column and a second protruding column to increase the length of the water outlet and increase the number of times of water flow scattering.

[0037] 10. The tenth technical solution is that the plurality of second water passing holes are obliquely arranged and evenly distributed around the axis of the water outlet hole corresponding to the second water passing holes, so that the water entering the water outlet hole generates a spiral flow, thereby increasing the bathing experience.

The mounting seat 111 is provided with a cylindrical mounting groove which is open at one end. The handle portion 112 is a hollow pipe body, and the inner cavity of the handle portion 112 communicates with the mounting groove from the side wall of the mounting groove. The water inlet pipe 15 is adapted to be mounted in the interior of the handle portion 112. The mounting groove is provided with a mounting column 1111 which extends towards the opening direction of the mounting groove on the bottom wall of the opening.

[0065] Reference Figure 2 、 Figure 4 The water outlet surface cover 14 is provided on the opening of the mounting groove and encloses to form a mounting cavity. The water distribution disc 12 and the water passing member 13 are mounted in the mounting cavity, and the water passing member 13 is closer to the water outlet surface cover 14 than the water distribution disc 12. The middle portions of the water distribution disc 12, the water passing member 13 and the water outlet surface cover 14 are provided with mounting holes for nesting with each other or for the fasteners to pass through.

A second cavity wall 181 is provided between the first cavity 17 and the second cavity 18, and a second water passing hole 1811 is provided on the second cavity wall 181 and penetrates through the water passing member 13. The water outlet hole 1711 gradually decreases in diameter along the water outlet direction, so that the hole wall of the water outlet hole 1711 is a conical surface, and the effect of dispersing water is better.

[0067] The water outlet surface cover 14 comprises a surface cover body. The surface cover body is towards the end wall of the water passing member 13, and the part of the end wall that participates in the enclosure of the first cavity 17 forms a first cavity wall 171. The first cavity wall 171 is provided with a first protruding column 141 on the surface facing the second cavity wall 181, and a second protruding column 142 on the surface facing away from the second cavity wall 181. The first protruding column 141 and the second protruding column 142 correspond to each other, and a water outlet hole 1711 penetrates through the first protruding column 141 and the second protruding column 142. The first protruding column 141 and the second protruding column 142 increase the length of the water outlet hole 1711 and increase the number of times of water flow dispersion.

[0068] Reference Figure 2 、 Figure 3 、 Figure 5 The water distribution disc 12 comprises a water distribution disc body 121, a first ring wall 122, a second ring wall 123, a third ring wall 124, and a toothed member 125.

The first hole is formed into a first water outlet 1211 at an end away from the water outlet surface cover 14, and the second hole is formed into a second water outlet 1212 at an end away from the water outlet surface cover 14. The first ring wall 122 is fixedly connected with the hole wall of the first hole and extends towards the direction of the water outlet surface cover 14, and the inner hole of the first ring wall 122 is in communication with the first hole.

[0069] The second ring wall 123 and the third ring wall 124 are provided on the water distribution disc body 121 and extend away from the water outlet surface cover 14 with equal extension lengths. The second ring wall 123 is provided with a water inlet 1231, the second ring wall 123 is arranged outside the third ring wall 124, the third ring wall 124 is arranged outside the first hole and the second hole, the first hole and the second hole are arranged on the bottom wall of the inner hole of the third ring wall 124, the third ring wall 124 is provided with a plurality of water passing holes 1241 arranged obliquely, the oblique direction of the water passing holes 1241 does not point to the central axis of the third ring wall 124, so that when water enters the inner hole of the third ring wall 124 through the water passing holes 1241, a rotational flow is formed. The inner wall of the third ring wall 124 is provided with a slot, the outer side wall of the toothed member 125 is provided with a protruding block 1253 matched with the slot, so as to realize the plug-in connection of the toothed member 125 and the third ring wall 124, which is convenient for installation and processing. The inner side wall of the toothed member 125 is provided with inner teeth 1251 arranged around a first axis and having a first number of teeth, and the first axis is the central axis of the third ring wall 124. The toothed member 125 is also provided with a plurality of third water passing holes 1252 with central axes parallel to the first axis, which are used to assist water passing.

[0070] The through water hole 1241 is obliquely arranged and points to the impeller to guide the rotation of the impeller to realize the rotation of the impeller. Compared with the water inlet 1231 directly impacting the impeller, since the number of the water inlet 1231 is limited compared with the through water hole 1241, the impact force is preferential, and the inclination angle is also inconvenient to set, so that the impeller is more easily driven through the through water hole 1241, and it is also more convenient to process.

[0071] Reference Figure 3 The cover plate 16 is adapted to be simultaneously arranged on the second ring wall 123 and the third ring wall 124, so that the area through which water passes among the cover plate 16, the second ring wall 123 and the water distribution disc body 121 forms a water passing cavity. Specifically, the water passing cavity is provided with a water inlet 1231, a first water collecting cavity 191, a through water hole 1241, a second water collecting cavity 192, a first water outlet 1211 and a second water outlet 1212.

[0072] Reference Figure 2 , Figure 3 , Figure 6 The water passing part 13 includes a water passing part body 131 and a fourth ring wall 132. The fourth ring wall 132 is protrudingly arranged on one side of the water passing part body 131 facing the water distribution disc body 121, and the inner hole of the fourth ring wall 132 penetrates through the water passing part body 131. The end wall of the water passing part body 131 facing the end wall of the water outlet face cover 14 which participates in enclosing the second cavity 18 to form a second cavity wall 181. The second water passing hole 1811 is an obliquely arranged hole which makes the water in the second cavity 18 obliquely hit the hole wall corresponding to the water outlet hole 1711 to be dispersed. Figure 7 In actual use, one water outlet hole 1711 can correspond to multiple second water passing holes 1811, and the multiple second water passing holes 1811 are obliquely arranged and uniformly distributed around the axis of the water outlet hole 1711 corresponding thereto, so that the water entering the water outlet hole 1711 generates a rotational flow, increasing the bathing experience. In this embodiment, one water outlet hole 1711 corresponds to three second water passing holes 1811.

[0073] Reference Figure 8, the rotating member 2 is a vane wheel, which is arranged in the second water collecting cavity 192 and rotatably connected with the cover plate 16 at one end around the first axis. In a specific implementation, the vane wheel is provided with a groove at the top end, and the cover plate 16 is provided with a protrusion at the bottom end, so that the rotating connection is realized after assembly. The bottom end of the vane wheel is further provided with an eccentric column, and the eccentric column is the output end of the vane wheel. The central axis of the eccentric column is a second axis parallel to the first axis.

[0074] With reference to Figure 1 , the switching member 3 is arranged in the second water collecting cavity 192. The switching member 3 includes an outer tooth 31 and a water passing part 32 which are fixed to each other. The outer tooth 31 is arranged around the second axis parallel to the first axis and is adapted to be engaged with the inner tooth 1251. The outer tooth 31 has a second number of teeth, and the second number of teeth is less than the first number of teeth. The outer tooth 31 is provided with a mounting hole with the second axis as the central axis. The mounting hole is inserted into the eccentric column of the vane wheel, so that the switching member 3 is rotatably connected to the vane wheel with the second axis as the rotation axis. The water passing part 32 extends in the circumferential direction relative to the outer tooth 31. When the water passing part 32 is installed in the second water collecting cavity 192, the tooth member 125 is sleeved on the outer tooth 31 and abuts against the water passing part 32, so that the water passing part 32 is limited below the tooth member 125, the water passing part 32 is attached to the bottom wall of the second water collecting cavity 192, and the outer tooth 31 is prevented from disengaging from the inner tooth 1251.

[0075] The water passing part 32 is further provided with a first water passing hole 321. The first water passing hole 321 penetrates through the water passing part 32 and is adapted to communicate with the water passing cavity and the first water outlet 1211 and the second water outlet 1212. In the embodiment, one opening of the first water passing hole 321 is formed on the bottom end face of the water passing part 32 and is adapted to abut against the first water outlet 1211 and the second water outlet 1212. The other opening is formed on the side wall of the water passing part 32 to communicate with the second water collecting cavity 192. In the embodiment, the first water passing hole 321 is preferably further extended towards the outer tooth 31 to the middle part of the outer tooth to increase the water passing area and ensure the normal and uninterrupted tooth number. By providing the first water passing hole 321 in the water passing part 32, the first water passing hole 321 communicates with the water passing cavity and the water outlet, so that water passing is realized. If the first water passing hole 321 is directly formed on the outer tooth 31, the strength of the outer tooth 31 is reduced and the outer tooth 31 is easily damaged. If the first water passing hole 321 is formed on the outer tooth 31, the tooth number of the outer tooth 31 needs to be kept normal and uninterrupted to make the outer tooth 31 and the inner tooth 1251 smoothly engaged. Therefore, the first water passing hole 321 cannot be arranged at the edge of the outer tooth 31, but only at the position close to the middle part. Therefore, the position of the water outlet needs to directly correspond to the position of the first water passing hole 321, and the position of the water outlet is not flexible enough.

[0076] During installation, the switching member 3 and the vane wheel are assembled and then arranged in the third ring wall 124 so that the inner tooth 1251 and the outer tooth 31 are engaged. Then the cover plate 16 is covered, and one end of the vane wheel is installed on the cover plate 16. At this time, the water passing hole 1241 points to the vane wheel, and the water entering through the water passing hole 1241 guides the vane wheel to rotate.

[0077] Then the water diversion disc 12 cover is provided on the water passing part 13, the water passing part 13 cover is provided on the water surface cover 14, the water surface cover 14 cover is provided on the installation slot of the shower body 11, and then the locking member is locked in sequence through the water surface cover 14, the water passing part 13 and the shower body 11, at this time, the first hole on the water diversion disc 12, the inner hole of the fourth ring wall 132 on the water passing part 13 and the first cavity 17 are communicated with each other; the second hole on the water diversion disc 12 is communicated with the second cavity 18.

[0078] The water flowing out of the second water collecting cavity 192 can have two water outlet paths, one is flowing out of the first water outlet 1211, and the water sequentially passes through the first hole, the inner hole of the first ring wall 122, the first cavity 17 and the water outlet hole 1711; the other is flowing out of the second water outlet 1212, and the water sequentially passes through the second hole, the second cavity 18, the second water passing hole 1811 and the water outlet hole 1711. Then the water inlet pipe 15 is sealingly inserted into the water inlet 1231, and the installation of the shower body 11 is completed.

[0079] In use, referring to Figure 10 , the water inlet 1231 is water in, the water enters the first water collecting cavity 191 and then enters the second water collecting cavity 192 through the water passing hole 1241, and drives the impeller to rotate relative to the body 1 about the first axis, since the output end of the impeller is parallel to the first axis, and the output end of the impeller is rotationally connected with the switching member 3, therefore, due to the eccentric arrangement of the output end, the impeller can drive the switching member 3 to move relative to the body 1 about the first axis when the impeller rotates about the first axis. And since the outer teeth 31 of the switching member 3 are engaged with the inner teeth 1251 of the body 1, and the output end of the switching member 3 is rotationally connected with the impeller, therefore, the switching member 3 can rotate relative to the impeller. When the impeller rotates about the first axis and drives the switching member 3 to move relative to the body 1 about the first axis, the state of the engagement of the outer teeth 31 with the inner teeth 1251 does not cause the switching member 3 to be stuck, but makes the switching member 3 rotate relative to the impeller with the second axis as the rotation axis, the teeth on the outer teeth 31 are disengaged from the inner teeth 1251, and after the switching member 3 rotates one tooth, the new teeth are re-engaged with the inner teeth 1251. During the engagement process, since the second number of teeth is less than the first number of teeth, when the switching member 3 is driven to rotate by the impeller, each tooth of the switching member 3 needs to be engaged with each tooth of the inner teeth once, and the time for the switching member 2 to rotate one circle will be greater than the time for the impeller to rotate one circle, the rotation speed ratio of the switching member 3 to the impeller is 1 / first number of teeth, that is, the speed reduction ratio is 1 / first number of teeth, so the function of speed reduction is realized.

[0080] When the impeller rotates around the first axis to drive the switching element 3 to move relative to the body 1 around the first axis, the position of the switching element 3 relative to the body 1 changes, causing the position of the first water passing hole 321 relative to the body 1 to change. When the switching element 3 rotates due to engagement, the position of the first water passing hole 321 relative to the body 1 changes due to rotation. The position changes of the first water passing hole 321 caused by the above two factors will change the communication state of the first water passing hole 321 with the first water outlet 1211 and the second water outlet 1212, thereby switching the water outlet state of the first water outlet 1211 and the second water outlet 1212, and ultimately affecting the water outlet of the water outlet hole 1711. Therefore, the movement of the switching element 3 relative to the body 1 around the first axis and the rotation of the switching element 3 around the second axis can both achieve the switching of the water outlet state, and the rotation of the switching element 3 plays a dominant role in the process of switching the water outlet state.

[0081] The change in water outlet state can refer to the change in opening and closing or the change in water outlet size, i.e. the change in opening and closing caused by the opening or complete shielding of the water outlet by the switching element 3, and the change in water outlet size caused by always opening the water outlet and changing the shielding area to change the area of the water outlet.

[0082] Reference Figure 11 When the water in the second water collecting cavity 192 is completely discharged from the first water outlet 1211 or the water discharge amount of the second water outlet 1212 is too small compared to the water discharge amount of the first water outlet 1211, the water finally flowing out of the water outlet hole 1711 appears as straight water in vision, as shown in Figure 12 When the water discharge amount from the second water outlet 1212 is continuously increasing, the water flowing out of the second water passing hole 1811 hits the hole wall of the corresponding water outlet hole 1711 due to the direction of the second water passing hole 1811 being towards the hole wall of the corresponding water outlet hole 1711, resulting in smaller particles, and the three second water passing holes 1811 are inclined and evenly distributed around the axis of the corresponding water outlet hole 1711, the water finally flowing out of the water outlet hole 1711 appears as swirling particle water in vision, as shown in Figure 13 When the water discharge amount from the second water outlet 1212 is the largest, as shown in Figure 14 Due to the effect of deceleration, the change speed of this process is not very fast, and people can feel the change from vision and experience. The automatic change process from straight water to particle water driven by water power can Figures 12-14 be automatically changed in a change cycle. The change process is infinitely variable, the particle size is infinitely variable, and the individual needs of consumers for different water particle sizes can be well met, the shower comfort and experience are improved, and the structure is easy to produce and process and has low cost, which is very practical.

[0083] The first number of teeth is preferably N, the second number of teeth is (N-1), each tooth of the external teeth 31 needs to engage with each tooth of the internal teeth 1251 once, therefore when the impeller rotates N times, the external teeth 31 rotates 1 time, the reduction ratio is 1 / N, which can reduce N times, and prevent the gear from engaging poorly when the number of teeth is too large. In this embodiment, the first number of teeth is 12-14, and the second number of teeth is 11-13, which prevents the strength from being insufficient due to too low number of teeth.

[0084] It should be appreciated that the rotating member 2 can also be a motor, which is provided with a transmission shaft rotating along the first axis and an output shaft, wherein one end of the transmission shaft extends along a direction parallel to the first axis, the output shaft forms an output end of the motor, the output shaft is parallel to the first axis and is fixedly connected with the transmission shaft, the motor drives the switching member 3 to move through the rotation of the output shaft, and the motor can be completely placed in the water passage or only the output shaft thereof is located in the water passage. The water outlet of the water passage in this embodiment includes a first water outlet 1211 and a second water outlet 1212, of course, only one or more water outlets can be provided, and the sizes of the first water outlet 1211 and the second water outlet 1212 can be set so that the first water passage 321 only communicates with one or allows to simultaneously communicate with two.
