[0004] At present, traditional shower heads generally switch the water spray of the shower head through manual switching structures such as rotating switching, pressing switching, and toggling switching. On the one hand, the user needs to actively control it, which is troublesome to operate. On the other hand, each switch can only make the shower head maintain the output of a single water spray, and it is impossible to achieve automatic switching between different water sprays.

[0005] Summary of the Invention

The water inlet and the at least two types of water outlet channels are respectively connected to the channel so that water flows from the water inlet into the channel and flows out from at least two types of water outlet channels, and the water splashes of the water flowing out of each type of water outlet channel are different. The switching assembly can be movably arranged in the channel and configured to enable the water inlet to selectively connect to one of the at least two types of water outlet channels. The switching assembly is configured to move under the action of the water flow, and alternately connect the water inlet to each type of water outlet channel.

[0008] The above solution provides a water outlet device that can be used in equipment such as shower heads and faucets. By utilizing a switching component disposed within the main body, the switching component is activated by the impact of the water flow, without the need for active manipulation. This allows water to alternately flow through different types of water outlet channels, thereby automatically switching between different water sprays.

[0057] The technical solutions in this disclosure will be described below with reference to the accompanying drawings.

[0058] Some embodiments of the present disclosure provide a water outlet device 100 capable of providing different types of water sprays, suitable for use in showers, faucets, or other devices capable of dispensing water. The water outlet device 100 provided in some embodiments of the present disclosure can solve the problem of existing showers being difficult to switch between water sprays and being unable to automatically switch between different water sprays.

[0059] Please refer to Figures 1-3. Figure 1 is a three-dimensional diagram of the water outlet device 100 in some embodiments of the present disclosure, Figure 2 is a three-dimensional exploded diagram of the water outlet device 100 in some embodiments of the present disclosure, and Figure 3 is a schematic diagram of the internal structure of the water outlet device 100 in some embodiments of the present disclosure.

[0060] In some embodiments of the present disclosure, a water outlet device 100 includes a body 10 and a switching assembly 20. A channel 10a is formed inside the body 10. The body 10 has a water inlet 11 and at least two types of water outlet channels 14. The water inlet 11 and the at least two types of water outlet channels 14 are respectively connected to the channel 10a, so that water flows from the water inlet 11 into the channel 10a and flows out through the at least two types of water outlet channels 14, and the water flowing out of each type of water outlet channel 14 has a different splash.

[0061] The switching assembly 20 is movably disposed within the channel 10a and configured to selectively connect the water inlet 11 to one of at least two types of water outlet channels 14. The switching assembly 20 is configured to move in response to water flow, alternately connecting the water inlet 11 to each type of water outlet channel 14.

[0062] The body 10 is the main component of the water outlet device 100 and provides a flow channel for water circulation. The water inlet 11 is the part where water flows from the outside into the internal channel 10a of the body 10, and the water outlet channel 14 is the flow channel for water to be discharged from the body 10.

[0063] It is worth mentioning that “at least two types of water outlet channels 14 ” can be understood as the body 10 having at least two types of water outlet channels 14 so as to provide at least two types of water sprays.

[0064] For example, in some embodiments of the present disclosure, the types of water sprays that can be provided by the main body 10 include but are not limited to large-flower shower water, small-flower shower water, massage water, bubble water, spray water, etc.

[0065] Among them, in some embodiments of the present disclosure, the water outlet channel 14 includes an inlet and an outlet (the inlet of the water outlet channel 14 is indicated by the label A in the figure), the inlet is located inside the main body 10, and is configured to be connected to the water inlet 11 through the channel 10a inside the main body 10. After the water flows into the channel 10a inside the main body 10 from the water inlet 11, it enters the water outlet channel 14 through the inlet of the water outlet channel 14, and is finally discharged from the water outlet channel 14.

[0066] In some embodiments of the present disclosure, please refer to Figure 2, the main body 10 may include a water inlet connector 12 and a water outlet body 13, and the water inlet connector 12 and the water outlet body 13 may be connected to each other by bonding, welding, screw connection or threaded connection, and the water inlet connector 12 forms a water inlet 11 at one end away from the water outlet body 13, and the water outlet body 13 forms a water outlet channel 14, and the outlet of the water outlet channel 14 is located at the end of the water outlet body 13 away from the water inlet connector 12.

[0067] The switching assembly 20 is a component disposed within the channel 10a, that is, the switching assembly 20 is a component disposed inside the body 10. In some embodiments of the present disclosure, the switching assembly 20 can be first disposed within the water outlet 13, and then the water inlet connector 12 can be assembled to the water outlet 13, thereby enclosing the cut flower assembly between the water inlet connector 12 and the water outlet 13.

[0068] In some embodiments of the present disclosure, water flows into the channel 10a from the water inlet 11, and the switching component 20 moves in the channel 10a due to the impact of the water flow, and the relative position relationship between the switching component 20 and the main body 10 changes, so that the switching component can block the inlet of at least one type of water outlet channel 14 out of at least two types of water outlet channels 14, allowing the inlet of the unblocked water outlet channel 14 to be connected to the water inlet 11.

[0069] It is worth mentioning that "alternatingly connecting the water inlet 11 to each type of water outlet channel 14" can be understood as the switching component 20 being impacted by the water flow and periodically changing its position so as to alternately allow the water to be discharged through different water outlet channels 14, thereby realizing the periodic switching of the water spray.

[0070] For example, in some embodiments of the present disclosure, the switching component 20 may include an impeller 22, which is affected by the impact of the water flow on the impeller 22, so that the impeller 22 can periodically block the inlets of different water outlet channels 14 and periodically connect different water outlet channels 14 to the water inlet 11.

[0071] The above solution provides a water outlet device 100 that can be configured in equipment such as a shower head and a faucet. Furthermore, the switching assembly 20 disposed within the body 10 utilizes the impact of the water flow to activate the switching assembly 20, without requiring active manipulation, and can alternately flow water from different types of water outlet channels 14, thereby achieving automatic switching of different water sprays.

[0072] According to some embodiments of the present disclosure, referring to FIG3 , a switching assembly 20 includes an impeller 22 and a switching member. The impeller 22 is rotatably disposed within the channel 10a and is drivingly connected to the switching member. The switching member is formed with a water diversion hole 240, through which the water inlet 11 communicates with a type of water outlet channel 14. The impeller 22 is configured to rotate under the action of water flow, thereby driving the switching member to rotate.

[0073] The impeller 22 is a part of the switching assembly 20 , and is rotatably disposed in the channel 10 a so as to rotate when impacted by the water flow.

[0074] For example, in some embodiments of the present disclosure, the impeller 22 may include a shaft 220 and blades 221. Please refer to Figures 4 and 5. Figure 4 is a schematic diagram of the impeller 22 in some embodiments of the present disclosure. There may be multiple blades 221, and multiple blades 221 are arranged at intervals on the circumference of the shaft 220. The end of the shaft 220 may be arranged at the water outlet 13 and can rotate relative to the water outlet 13. When the water flow is discharged from the water inlet 11 into the channel 10a and is configured as blades 221, the blades 221 will drive the shaft 220 to rotate, thereby driving the switching member connected to the shaft 220.

[0075] In some embodiments of the present disclosure, the switching member may be plate-shaped, and the switching member may include a first area and a second area. The first area is configured to close the inlet of the water outlet channel 14 to cut off the water inlet 11 and the water outlet channel 14. The second area is formed with a water diversion hole 240, and the water diversion hole 240 passes through the switching member and is configured to conduct any type of water outlet channel 14 and the water inlet 11.

[0076] For example, referring to FIG3 , the main body 10 includes two types of water outlet channels 14: a first type of water outlet channel 14a and a second type of water outlet channel 14b. When the impeller 22 is not impacted by the water flow, the water diversion hole 240 connects the water inlet and the first type of water outlet channel 14a, and other parts of the switching element close the inlet of the second type of water outlet channel 14b. When the impeller 22 is impacted by the water flow, the impeller 22 drives the switching element to rotate, and the position of the water diversion hole 240 changes so that the second type of water outlet channel 14b can be connected, and other parts of the switching element close the inlet of the first type of water outlet channel 14a. As the water flow continues to impact, the impeller 22 drives the switching element to rotate periodically, alternately connecting and closing the first type of water outlet channel 14a and the second type of water outlet channel 14b. Of course, in other embodiments of the present disclosure, the main body 10 also includes three types of water outlet channels 14, four types of water outlet channels 14, etc.

[0077] Through the above scheme, by setting the impeller 22 and utilizing the kinetic energy of the water flow, when the water flows through, the rotation of the impeller 22 can drive the movement of the switching component, so that the water diversion hole 240 alternately connects the water inlet 11 and each type of water outlet channel 14, so that different types of water outlet channels 14 discharge water alternately, thereby realizing automatic switching of different water sprays.

[0078] According to some embodiments of the present disclosure, as shown in FIG2 , a body 10 includes a separate water inlet connector 12 and a water outlet body 13 . The water inlet connector 12 and the water outlet body 13 are interconnected and together form a channel 10a . A water inlet 11 is formed in the water inlet connector 12 , and at least two types of water outlet channels 14 are formed in the water outlet body 13 .

[0079] In some embodiments of the present disclosure, the main body 10 may be a split structure, comprising a water inlet connector 12 and a water outlet 13 connected to each other. In some embodiments of the present disclosure, the connection between the water inlet connector 12 and the water outlet 13 includes, but is not limited to, bonding, welding, threaded connection, or other connection relationships such as threaded fitting. Of course, in other embodiments of the present disclosure, the main body 10 and the switching assembly 20 may also be integrally formed via 3D printing.

[0080] In some embodiments of the present disclosure, referring to Figures 2, 3, and 5, the water inlet connector 12, the impeller 22, and the water outlet 13 may be arranged along the axial direction z of the impeller, and the axial direction of the water inlet 11 may be parallel to the axial direction z of the impeller. In other embodiments, the axial direction of the water inlet 11 may not be parallel to the axial direction z of the impeller. For example, in Figure 3, the axial direction of the water inlet 11 may be in the up-down direction, and in other embodiments, the axial direction of the water inlet 11 may also be in the left-right direction.

[0081] In the above solution, the main body 10 includes a water inlet joint 12 and a water outlet body 13 which are separate structures from each other. On the one hand, it can reduce the manufacturing difficulty of the main body 10, and on the other hand, it can facilitate the assembly of the switching component 20 and improve the manufacturing efficiency of the water outlet device 100.

[0082] According to some embodiments of the present disclosure, please refer to Figures 2, 3 and 5. Along the axial direction z of the impeller, a receiving groove 130 is formed at one end of the water outlet body 13, the inlet of the water outlet channel 14 is formed at the bottom of the receiving groove 130, and the impeller 22 is rotatably connected to the bottom of the receiving groove 130.

[0083] The switching member includes an internal gear 23 and an external gear 24, which are arranged at the bottom of the accommodating groove 130. The external gear 24 is arranged around the outer periphery of the internal gear 23. The water diversion hole 240 is formed on the external gear 24. The internal gear 23 and the external gear 24 are engaged with each other through teeth. The impeller 22 is connected to the internal gear 23 and drives the external gear 24 to rotate through the internal gear 23.

[0084] In some embodiments of the present disclosure, referring to FIG9 , the water outlet body 13 includes a first portion 131 and a second portion 132, which are connected to each other along the axial direction z of the impeller. The first portion 131 is arranged around the surface of the second portion 132 to form a receiving groove 130 together with the second portion 132. The first portion 131 constitutes the groove wall of the receiving groove 130, and the surface of the second portion 132 constitutes the groove bottom of the receiving groove 130. The water outlet channel 14 is formed in the second portion 132, and the inlet of the water outlet channel 14 is formed at the groove bottom of the receiving groove 130. The inlets of different types of water outlet channels 14 are spaced apart around the axial direction z of the impeller.

[0085] In some embodiments of the present disclosure, referring to the drawings, the inlet of the water outlet channel 14 includes a first inlet 13a and a second inlet 13b, and the first inlet 13a and the second inlet 13b are spaced apart around the axial direction z of the impeller.

[0086] For example, referring to Figures 7 and 10 , the inlet of the water outlet channel 14 includes a first inlet 13a and a second inlet 13b. The first inlet 13a is connected to the first type of water outlet channel 14a, so that when the water diversion hole 240 connects the water inlet and the first type of water outlet channel 14a, water flows through the first inlet 13a into the first type of water outlet channel 14a. The second inlet 13b is connected to the second type of water outlet channel 14b, so that when the water diversion hole 240 connects the water inlet and the second type of water outlet channel 14b, water flows through the second inlet 13b into the second type of water outlet channel 14b.

[0087] In some embodiments of the present disclosure, referring to FIG. 7 and FIG. 8 , a rotation groove 1300 is formed at the bottom of the accommodating groove 130 , and the end of the shaft 220 of the impeller 22 is disposed in the rotation groove 1300 so as to be able to rotate relative to the water outlet 13 .

[0088] The internal gear 23 is connected to the impeller 22 and has teeth formed on its outer circumference. The external gear 24 is an annular structure, with a water diversion hole 240 formed in it and extending through two opposing walls of the external gear 24 along the axial direction of the impeller 22. The inner ring of the external gear 24 is also toothed. The internal gear 23 is mounted on the inner ring of the external gear 24, and the two gears mesh with each other.

[0089] In some embodiments of the present disclosure, referring to Figures 5-6, the teeth of the internal gear 23 may partially mesh with the teeth of the external gear 24. For example, the inner ring size of the external gear 24 is larger than the outer profile size of the internal gear 23. The impeller 22 drives the internal gear 23 to swing within the external gear 24, driving the external gear 24 to rotate within the receiving groove 130, thereby changing the position of the water diversion hole 240 within the receiving groove 130. In other embodiments, the teeth of the internal gear 23 may fully mesh with the teeth of the external gear 24. For example, the impeller 22 drives the internal gear 23 to rotate within the external gear 24, thereby driving the external gear 24 to rotate within the receiving groove 130, thereby changing the position of the water diversion hole 240 within the receiving groove 130.

[0090] In some embodiments of the present disclosure, the external gear 24 may be sealed with the groove wall of the accommodating groove 130 so that water can only flow to the water outlet channel 14 through the water diversion hole 240 .

[0091] In the above scheme, by arranging the internal gear 23 and the external gear 24 in the accommodating groove 130, when the impeller 22 is rotated by the water flow, the external gear 24 can be stably driven to rotate, thereby realizing the periodic and alternating connection of the water diversion hole 240 to the water inlet 11 and each type of water outlet channel 14, so that different types of water outlet channels 14 discharge water alternately, thereby realizing automatic switching of different water sprays.

[0092] According to some embodiments of the present disclosure, the impeller 22 includes a shaft 220, blades 221, and an eccentric wheel 222. Please refer to Figures 4 and 12. Figure 12 is a schematic diagram of the internal gear 23, the external gear 24, and the water outlet 13 in some embodiments of the present disclosure. The blades 221 and the eccentric wheel 222 are disposed on the circumference of the shaft 220, and one end of the shaft 220 is rotatably connected to the bottom of the receiving groove 130. The internal gear 23 is formed with a through hole 230, which cooperates with the eccentric wheel 222. The impeller 22 is configured to drive the internal gear 23 to swing.

[0094] The eccentric wheel 222 is eccentrically arranged relative to the rotation axis of the impeller 22. The through hole 230 of the internal gear 23 can accommodate the eccentric wheel 222 and the shaft 220. When the blades 221 are impacted by the water flow and drive the shaft 220 to rotate, the eccentric wheel 222 can drive the internal gear 23 to deflect.

[0095] In the above scheme, by setting the eccentric wheel 222 and the through hole 230 of the internal gear 23 to cooperate with each other, when the impeller 22 is rotated by the water flow, it can drive the internal gear 23 to swing in a circle in the receiving groove 130, thereby driving the external gear 24 to perform uniform circular rotation motion, so that the water diversion hole 240 periodically and alternately connects the water inlet 11 and each type of water outlet channel 14, so that different types of water outlet channels 14 alternately discharge water, thereby realizing automatic switching of different water sprays.

[0096] According to some embodiments of the present disclosure, please refer to Figure 6, a limiting column 1301 is set at the bottom of the accommodating groove 130, the internal gear 23 forms a limiting groove 231, the limiting column 1301 is set in the limiting groove 231, and the internal gear 23 is configured to swing along the circumference of the limiting column 1301.

[0097] The limiting post 1301 is a component that protrudes from the bottom of the receiving groove 130. The limiting post 1301 cooperates with the limiting groove 231 formed in the internal gear 23. The outer contour of the limiting post 1301 is smaller than the dimensions of the limiting groove 231, allowing the internal gear 23 to swing back and forth along the circumference of the limiting post 1301.

[0098] In some embodiments of the present disclosure, there are multiple limiting posts 1301 , for example, there are four limiting posts 1301 , and the four limiting posts 1301 are distributed in a rectangular array, and correspondingly, the inner gear 23 is formed with four limiting grooves 231 .

[0099] In the above scheme, by setting a limit column 1301 at the bottom of the groove, the swing range of the internal gear 23 can be constrained, so that the internal gear 23 can stably swing in a limited space under the drive of the impeller 22, which can improve the uniformity of the rotation of the external gear 24 and improve the uniformity of the automatic switching of the water splash.

[0100] According to some embodiments of the present disclosure, referring to FIG. 2 and FIG. 3 , the water outlet device 100 further includes an inclined water body 25 . The inclined water body 25 is closer to the water inlet 11 than the impeller 22 . An inclined water hole 250 is formed on the inclined water body 25 .

[0101] In some embodiments of the present disclosure, the inclined water body 25 may be a plate-shaped structure, and the inclined water holes 250 formed on the inclined water body 25 may be arranged toward the blades 221 of the impeller 22 .

[0102] In some embodiments of the present disclosure, a plurality of inclined water holes 250 are formed on the inclined water body 25 , and the plurality of inclined water holes 250 are arranged at intervals.

[0103] In some embodiments of the present disclosure, the inclined water body 25 is connected to the inner wall of the water outlet body 13. For example, the inner wall of the water outlet body 13 is formed with a stepped surface, and the inclined water body 25 is overlapped on the stepped surface. The connection relationship between the inclined water body 25 and the stepped surface includes but is not limited to bonding, welding, screw connection, etc.

[0104] In some embodiments of the present disclosure, the inclined water body 25 is formed with a matching groove, and the end of the shaft 220 of the impeller 22 can be accommodated in the matching groove.

[0105] In the above solution, by providing the inclined water body 25, the direction of the water flow toward the impeller 22 can be changed, thereby smoothly driving the impeller 22 to rotate, and further smoothly realizing the automatic switching of different water sprays.

[0106] According to some embodiments of the present disclosure, the outlets of each type of water outlet channel 14 are oriented in the same direction. Referring to FIG12 , FIG12 is a schematic diagram of the internal structure of the water outlet body 13 in some embodiments of the present disclosure.

[0107] It is worth mentioning that "the outlet of each type of water outlet channel 14 has the same direction", which can be understood as that the direction of the water sprayed out by the water outlet device 100 is the same, that is, the direction of the water sprayed out is the same by utilizing the water flow to realize automatic switching of different water outlet splashes.

[0108] In other embodiments of the present disclosure, the outlets of each type of water outlet channel 14 are oriented in different directions. Referring to Figures 11 and 12 , Figure 11 is a bottom view of the water outlet body 13 in other embodiments of the present disclosure, and Figure 12 is a schematic diagram of the internal structure of the water outlet body 13 in other embodiments of the present disclosure.

[0109] It is worth mentioning that "the outlet of each type of water outlet channel 14 has a different direction", which can be understood as that the directions of the water flows sprayed out of different water outlet channels 14 are different, that is, the directions of the water sprayed out are different when the water flow is used to automatically switch between different water outlet splashes.

[0110] In the above solution, in some embodiments of the present disclosure, by setting the outlets of different water outlet channels 14 in the same direction, different types of water sprays can be provided to the user in the same direction. Of course, in other embodiments of the present disclosure, by setting the outlets of different water outlet channels 14 in different directions, different types of water sprays can be provided to the user in different directions.

[0111] According to some embodiments of the present disclosure, referring to FIG. 8 and FIG. 9 , the body 10 further has a water outlet 26 .

[0112] In some embodiments of the present disclosure, the water outlet nozzle 26 is a component protruding from the end surface of the water outlet body 13 away from the water inlet joint 12. The water outlet nozzle 26 is configured to spray water.

[0114] Alternatively, in other embodiments of the present disclosure, as shown in Figures 11 and 12 , the outlet of each type of water outlet channel 14 is connected to the same water outlet nozzle 26, so that water flows out from the same water outlet nozzle 26. In Figures 11 and 12 , the outlet of each type of water outlet channel 14 faces a different direction, so the direction of the water sprayed from the water outlet nozzle 26 of each type of water outlet channel 14 is also different.

[0115] According to some embodiments of the present disclosure, a shower head is further provided, comprising the above-mentioned water outlet device 100. In some embodiments, the shower head may further comprise a handle connected to the outlet body 10, wherein a water supply pipe is formed inside the handle and communicated with the water inlet 11.

[0116] According to some embodiments of the present disclosure, a water outlet device 100 is provided. The water outlet device 100 includes a body 10, a switching assembly 20, and an inclined water body 25. The body 10 includes a water inlet connector 12 and a water outlet 13. The switching assembly 20 includes an impeller 22, an internal gear 23, and an external gear 24.

[0117] The water inlet connector 12 and the water outlet 13 are connected to each other and together form a channel 10a configured to accommodate the inclined water body 25 and the switching assembly 20. The water inlet connector 12 is formed with a water inlet 11, and the water outlet 13 is formed with a first type of water outlet flow channel 14a and a second type of water outlet flow channel 14b.

[0118] In particular, along the axial direction z of the impeller, a receiving groove 130 is formed at one end of the water outlet body 13. The inlet of the water outlet channel 14 is formed at the bottom of the receiving groove 130, and the inlets of different types of water outlet channels 14 are distributed around the axial direction z of the impeller. The impeller 22 is rotatably connected to the bottom of the receiving groove 130. The impeller 22 is connected to the internal gear 23 via an eccentric wheel 222. A limiting post 1301 is provided at the bottom of the receiving groove 130. The limiting post 1301 cooperates with the limiting groove 231 of the internal gear 23. The internal gear 23 and the external gear 24 engage with each other through tooth meshing. The external gear 24 is formed with a water diversion hole 240, which is configured to selectively connect the water inlet 11 and the inlet of the water outlet channel 14.

[0119] The working principle and beneficial effects of the water outlet device proposed in this embodiment include:

[0120] The water outlet device 100 drives the impeller 22 to rotate through the incoming water flow, and the eccentric wheel 222 on the impeller 22 drives the internal gear 23 to move. Under the action of the limiting column 1301 of the water outlet body 13, the limiting groove 231 of the internal gear 23 performs a circular swing in a limited space, thereby driving the external gear 24 to perform uniform circular rotation. At the same time, a water diversion hole 240 is provided on the external gear 24, and two corresponding inlets of the water outlet channel 14 are provided on the water outlet body 13, wherein a first inlet 13a corresponds to the first type of water outlet channel 14a, and the other second inlet 13b corresponds to the second type of water outlet channel 14b.

[0121] When the water diversion hole 240 is connected to the first type of water outlet channel 14a through the first inlet 13a, water splashes out of the first type of water outlet channel 14a; when the water diversion hole 240 is connected to the second type of water outlet channel 14b through the second inlet 13b, water splashes out of the second type of water outlet channel 14b.

[0122] In summary, water flows through the water inlet 11 into the channel 10a and acts on the impeller. The impeller 22 rotates under the continuous impact of the water flow. The impeller's rotation drives the internal gear 23, which in turn drives the external gear 24 in a circular motion. The rotation of the external gear 24 controls the water diversion hole 240, alternating between the first and second outlet channels 14a, 14b. This allows water to alternately flow through the first and second outlet channels 14a, 14b, thus achieving automatic switching of the water flow.

[0123] The foregoing description is merely a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
