[0025] Figures 1 to 8 The water outlet device 100 of one embodiment of the present invention is shown, and the water outlet device 100 includes a main body 101, a water outlet nozzle 125, a water outlet bar 103 and a driving assembly. The main body 101 is provided with a water inlet 102 (such as Figure 1 As shown, the water outlet 125 is provided with a water outlet 138 (as shown Figure 5 As shown). The water outlet strip 103 is elastic and can be deformed. For example, the water outlet strip 103 can be made of silica gel. Figure 4 As shown, the water outlet bar 103 is located outside the main body 101, and the water outlet bar 103 is hollow. A first flow channel 135 with two ends passing through is formed inside the water outlet bar 103. One end of the water outlet bar 103 is connected to the water outlet nozzle 125, so that the first flow channel 135 is connected to the water outlet 138. Figure 4 The water outlet device 100 is shown in the water outlet state. In the water outlet state, water can enter the water outlet device 100 from the water inlet 102, then enter the first flow channel 135 inside the water outlet bar 103 through the water outlet nozzle 125, and finally flow out from the end of the water outlet bar 103 away from the water outlet nozzle 125. The driving component is installed inside the main body 101. The driving component is used to drive the water outlet nozzle 125 to move relative to the main body 101 when the water outlet nozzle 125 discharges water, so as to change the direction of the water outlet 138. In some embodiments, the driving component may include a motor and a transmission mechanism, and the motor drives the water outlet nozzle 125 to rotate through the transmission mechanism; in other embodiments, the driving component may not include a motor, and the driving component drives the water outlet nozzle 125 to move through the force of the water flow. This driving component will be described in detail below.

[0026] The working principle of the water outlet device 100 is described below. Figure 4 and Figure 6 The water outlet state and the water off state of the water outlet device 100 are shown respectively. Figure 6As shown, in the water-off state, no water enters the water outlet device 100, the water outlet nozzle 125 and the water outlet bar 103 do not move, and the water outlet bar 103 naturally droops under the action of gravity. The water outlet bar 103 is generally arc-shaped and nearly straight. Figure 4 As shown, in the water outlet state, water enters the water outlet device 100, the water outlet nozzle 125 can discharge water, and the driving component drives the water outlet nozzle 125 to move. As the water outlet nozzle 125 moves, the water outlet bar 103 connected to the water outlet nozzle 125 also moves. Moreover, the impact of the water flow in the first flow channel 135 on the water outlet bar 103 will cause a certain deformation of the water outlet bar 103. Therefore, in the water outlet state, the water outlet bar 103 will twist and wave, and the water flowing out of the water outlet bar 103 will also dance.

[0027] When the water outlet device 100 of the present invention is discharging water, the water flow will dance and the water outlet bar 103 will also twist. The dancing effect of the water flow and the twisting effect of the water outlet bar 103 are combined to enhance the visual effect of the water outlet device 100 when discharging water, thereby improving the user experience. It should be noted that the prior art usually only pursues the visual effect of the water flow, and usually only considers making improvements in the dancing form of the water flow itself to enhance the user's visual experience. The present invention adopts a different concept from the prior art. The present invention improves the structure of the water outlet device 100 itself on the basis that the water flow can dance, and further enhances the overall visual effect of the water outlet device 100 when discharging water through the visual effect brought about by the twisting of the water outlet bar 103.

[0028] In some embodiments, Figure 8 As shown, the water outlet device 100 can be embedded in the ceiling 201 of the bathroom. In other embodiments, such as Fig. 9 As shown, the water outlet device 100 may also be embedded in the side wall 202 of the bathroom, so that the water outlet device 100 can spray water to the user from the side of the user's body. Fig. 9 The water outlet device 100 shown in the figure omits the water outlet bar 103. When the water outlet bar 103 is not installed, the water flow 203 sprayed from the water outlet nozzle 125 will periodically contract inwards and expand outwards (in Fig. 9 After the water outlet 125 is installed with the water outlet bar 103, the dancing manner of the water flow sprayed from the water outlet bar 103 is similar to the dancing manner of the water flow sprayed from the water outlet 125. The water outlet device 100 does not necessarily need to be embedded in the ceiling 201 or the side wall 202. In other embodiments not shown in the figure, the water outlet device 100 can also be used as a top shower or a hand shower.

[0029] In some embodiments, in order to allow the water outlet bar 103 to have a better twisting effect when discharging water, the length L of the water outlet bar 103 can meet the following conditions: 100mm≤L≤120mm. The "length of the water outlet bar 103" refers to the length of the water outlet bar 103 in a straight state. L being not less than 100mm can prevent the water outlet bar 103 from being too short, thereby preventing the twisting effect of the water outlet bar 103 from being unclear. L being not greater than 120mm can prevent the water outlet bar 103 from being too long, thereby preventing the water outlet bar 103 from being unable to twist effectively due to being too long and too heavy.

[0030] In some embodiments, the water outlet device 100 may further include a light source 120 . The light source 120 may be configured as a ring-shaped LED light strip. The light emitted by the light source 120 may further enhance the aesthetics or visual effect of the water outlet device 100 .

[0031] like Figure 4 As shown, the main body 101 includes a fixed body 127 and a movable body 128, the water inlet 102 is arranged on the fixed body 127, and the water outlet 125, the driving assembly and the light source 120 are all installed on the movable body 128. In this embodiment, the fixed body 127 includes an embedded shell 104, a first base body 105 and a second base body 111. The embedded shell 104 can be embedded in the ceiling 201 or the side wall 202 (refer to Figure 8 or Fig. 9 ). The first seat body 105 and the embedded shell 104 are fixed to each other, the water inlet 102 is set at the top of the embedded shell 104, a part of the first seat body 105 is located in the embedded shell 104, and the water outlet 138 extends out of the embedded shell 104. The second seat body 111 is fixed inside the first seat body 105, for example, the two are fixed by a threaded connection. Figure 4 As shown, in this embodiment, the movable body 128 includes an inclined water body 112, a water sealing cover 118 and a panel 126. The inclined water body 112 is connected to the top of the water sealing cover 118, and the panel 126 is connected to the bottom of the water sealing cover 118 by screws 117. The driving assembly is located in a chamber surrounded by the water sealing cover 118 and the panel 126. The panel 126 includes a water outlet surface 129, and the water outlet surface 129 is provided with a plurality of through holes. One end of the water outlet 125 provided with a water outlet 138 extends out of the panel 126 through the through holes.

[0032] It should be noted that the parts included in the fixed body 127 and the movable body 128 can also be appropriately increased or decreased. For example, in other embodiments not shown in the figure, the first seat body 105 and the embedded shell 104 can be set as an integrated part. For another example, if the water outlet device 100 does not rely on the water flow to drive the water outlet 125 to rotate, then the inclined water body 112 can be omitted. Examples are not given here one by one. In addition, the water sealing cover 118 is provided with an avoidance hole 153, which is located below the impeller 115, and the avoidance hole 153 allows water to pass through (the avoidance hole 153 is only Figure 7 Shown, not in Figure 4 shown).

[0033] The movable body 128 includes a first outer peripheral surface 130, and the first outer peripheral surface 130 surrounds the water outlet surface 129. Figure 5 As shown, the first peripheral surface 130 may be specifically the peripheral surface of the panel 126. The light source 120 is disposed on the first peripheral surface 130, and the light emitting surface of the light source 120 is located on the side of the light source 120 facing away from the first peripheral surface 130, so that the light source 120 can emit light outward. Figure 4 and Figure 6 The movable body 128 can be movably disposed inside the fixed body 127. For example, the movable body 128 can be slidably disposed inside the embedded shell 104. The movable body 128 can move to a first position and a second position relative to the fixed body 127. Figure 6 In the embodiment, the movable body 128 is in the first position, at which time the light source 120 is located inside the fixed body 127 and the light source 120 is turned off. Figure 4 In the embodiment, the movable body 128 is in the second position, at which time the light source 120 is exposed outside the fixed body 127 and is turned on (i.e., the light source 120 emits light). The light effect produced by the light source 120 can improve the aesthetics and visual effect of the water outlet device 100. Moreover, since the movable body 128 and the light source 120 can be stored inside the fixed body 127, when the light source 120 does not need to be turned on, the space occupied by the water outlet device 100 is small.

[0034] It should be noted that when the water outlet device 100 is embedded in the ceiling 201 or the side wall 202 for use, when the movable body 128 is in the second position, the light source 120 is still exposed outside the ceiling 201 and the side wall 202 so that the user can see the light of the light source 120.

[0035] Further, in some embodiments, when the movable body 128 is in the second position, the light source 120 is turned on, and the water inlet 102, the water outlet 138 and the first flow channel 135 are sequentially connected, and the water outlet strip 103 can discharge water (such as Figure 4 As shown). In this arrangement, when the water outlet device 100 is discharging water, the light effect of the light source 120, the dancing effect of the water flow and the twisting effect of the water outlet bar 103 are combined to bring a good visual experience to the user. Accordingly, when the movable body 128 is in the first position, the light source 120 is turned off, and the water inlet 102 and the water outlet 138 are separated from each other (separation means that water cannot flow from the water inlet 102 to the water outlet 138), and the water outlet bar 103 cannot discharge water (such as Figure 6 as shown).

[0036] In order to synchronize the extension of the light source 120 and the water discharge of the water discharge bar 103, in some embodiments, the water discharge device 100 includes a piston 106 and an elastic member 107. Figure 4 As shown, the piston 106 is movably disposed in the fixed body 127, for example, the piston 106 is located inside the first seat body 105, and the bottom end of the piston 106 is slidably sleeved on the top end of the second seat body 111. The piston 106 is in transmission connection with the movable body 128, and the first seat body 105 of the fixed body 127 has a water outlet 131. Figure 6 As shown, when the movable body 128 is in the first position, the piston 106 blocks the water inlet 131, thereby separating the water inlet 102 and the water outlet 138; Figure 4 As shown, when the movable body 128 is in the second position, the piston 106 releases the blocking of the water outlet 131, and the piston 106 no longer separates the water inlet 102 and the water outlet 138. The fixed body 127 is connected to the elastic member 107, and the movable body 128 is connected to the elastic member 107. For example, the elastic member 107 is sleeved on the outside of the second seat body 111, the top end of the elastic member 107 abuts against the piston 106, and the bottom end of the elastic member 107 abuts against the second seat body 111. Figure 4 As shown, the elastic member 107 is configured such that the external water pressure at the water inlet 102 (i.e., the water pressure at the water inlet 102 and at the top of the piston 106) can overcome the elastic force of the elastic member 107, thereby driving the piston 106 to move (downward), thereby causing the movable body 128 to move from the first position to the second position. Figure 4 and Figure 6 When the external water pressure at the water inlet 102 is eliminated, the elastic force of the elastic member 107 is used to drive the piston 106 to reset (move upward), thereby restoring the blocking of the water outlet 131 by the piston 106 .

[0037] Extending and turning on the light source 120 at the same time when discharging water is also conducive to improving the sense of science and technology of the water outlet device 100 and improving the visual effect of the water outlet device 100. Under the above setting mode, as long as water with sufficient pressure is delivered to the water inlet 102, the movable body 128 and the light source 120 will extend, and the water outlet bar 103 can also discharge water at the same time. This embodiment achieves the synchronization of the water outlet bar 103 and the extension of the light source 120 in a simple and low-cost manner. This setting mode does not need to control the water outlet by detecting the position of the movable body 128, and the water outlet device 100 does not need to be equipped with a complex and high-cost electromagnetic valve.

[0038] It should be noted that although Figure 4 and Figure 7 The outer peripheral surface of the middle piston 106 is still in contact with the first seat body 105 , but water can pass through the piston 106 in this state. Fig.10The internal structure of the first seat body 105 is shown. In addition to the water inlet 102, the first seat body 105 also includes a water outlet 131 and a plurality of anti-slip ribs 132. The water outlet 131 is located downstream of the water inlet 102 and upstream of the water outlet 138. The anti-slip ribs 132 are located downstream of the water outlet 131. There is a gap 143 between two adjacent anti-slip ribs 132, and the gap 143 allows water to pass through. The plurality of anti-slip ribs 132 surround the piston 106 together. Figure 6 As shown, when the piston 106 is located above the anti-slip rib 132 and the outer circumference of the piston 106 is in close contact with the inner circumference of the water outlet 131, the water outlet 131 is blocked and the water inlet 102 and the water outlet 138 are separated. Figure 4 or Figure 7 As shown, after the piston 106 is driven downward by the water pressure, the outer peripheral surface of the piston 106 abuts against the anti-slip rib 132, and the piston 106 releases the blockage of the water outlet 131, and water can flow through the water inlet 102, the water outlet 131, the anti-slip rib 132, the water outlet 138, and the first flow channel 135 of the water outlet bar 103 in sequence.

[0039] As described above, the piston 106 is in transmission connection with the movable body 128, and the movement of one can drive the movement of the other. Figure 4 As shown, in some embodiments, the water outlet device 100 further includes a cam 110 and a connecting rod 108. The cam 110 is in contact with the movable body 128. The connecting rod 108 and the cam 110 are both arranged on the side of the piston 106 facing away from the water inlet 102, and the connecting rod 108 and the cam 110 are both located between the piston 106 and the movable body 128. The two ends of the connecting rod 108 are respectively a first end and a second end. In this embodiment, the first end is the top end of the connecting rod 108, and the second end is the bottom end of the connecting rod 108. The first end is rotatably connected to the piston 106, and the second end is rotatably connected to the cam 110, and the second end is spaced apart from the rotation axis of the cam 110. The cam 110 is rotatably connected to the fixed body 127. For example, the cam 110 is connected to the second seat body 111 through the pin 109, and the center axis of the pin 109 is the rotation axis of the cam 110.

[0040] Please combine Figure 4 and Figure 6When the external water pressure drives the piston 106 to move downward, the elastic member 107 gradually contracts, the position of the cam 110 that abuts the movable body 128 also changes, the distance between the rotation axis of the cam 110 and the movable body 128 gradually increases, and the movable body 128 and the light source 120 gradually move downward. When the external water pressure is eliminated, the originally compressed elastic member 107 drives the piston 106 to move upward, thereby driving the connecting rod 108 and the cam 110 to move, the position of the cam 110 that abuts the movable body 128 gradually changes, the distance between the rotation axis of the cam 110 and the movable body 128 gradually decreases, and the movable body 128 and the light source 120 gradually rise. In this embodiment, the piston 106 drives the movable body 128 to move by abutting the cam 110 with the movable body 128, which is conducive to improving the smoothness of the movement process of the movable body 128 and reducing the risk of the movable body 128 being stuck.

[0041] In other embodiments not shown, in order to reduce the number of parts and improve assembly convenience, the water outlet device 100 may not be provided with the cam 110. For example, the piston 106 and the movable body 128 are connected to the two ends of the connecting rod 108 respectively.

[0042] In some embodiments, the electric energy required for the light source 120 to emit light can be generated by the water outlet device 100. In this way, the water outlet device 100 does not need a built-in battery, and the user does not need to frequently replace the battery for the water outlet device 100. In addition, the water outlet device 100 does not need to be connected to an external power source through a wire, which helps to reduce the risk of electric shock to the user due to leakage of the water outlet device 100.

[0043] Specifically, Figure 7 As shown, the driving assembly includes an impeller 115 that can be driven by the water flow in the main body 101 (the driving assembly is described in detail below), and the water outlet device 100 also includes a generator 114. The generator 114 and the impeller 115 are both installed inside the main body 101. More specifically, the impeller 115 and the generator 114 are both located in a chamber surrounded by the inclined water body 112 and the water sealing cover 118, and the generator 114 is connected to the impeller 115. The generator 114 is also electrically connected to the light source 120, for example, Figure 6As shown, the water outlet device 100 includes a circuit board 113 and a wire 121, a generator 114 is connected to the circuit board 113, and the circuit board 113 and the light source 120 are respectively connected to the two ends of the wire 121, so as to realize the electrical connection between the generator 114 and the light source 120. When the water flow drives the impeller 115 to rotate, the driving component drives the water outlet 125 to move so that the water outlet bar 103 twists, and the generator 114 generates electricity to supply power to the light source 120. In this way, while the water outlet bar 103 is discharging water and twisting, the light source 120 will also emit light. Moreover, the generator 114 and the driving component share an impeller 115, which is conducive to reducing the number of parts of the water outlet device 100, thereby reducing the cost of the water outlet device 100 and improving the assembly convenience of the water outlet device 100.

[0044] It is described above that the light source 120 can extend and emit light when the water outlet bar 103 is out of water. In other embodiments not shown, the light source 120 can also be arranged in other ways. For example, the panel 126 and the embedded shell 104 are completely fixed, the outer surface of the main body 101 also includes a second outer peripheral surface, the second outer peripheral surface is the outer peripheral surface of the embedded shell 104, the second outer peripheral surface surrounds the water outlet surface 129, and the second outer peripheral surface and the water outlet surface 129 are fixed to each other, and the light source 120 is arranged on the second outer peripheral surface. In this way, there is no need to set a mechanism for the light source 120 to be retracted in the water outlet device 100, which is conducive to reducing the cost of the water outlet device 100. For another example, the light source 120 can be arranged on the water outlet surface 129, so that the light emitted by the light source 120 can be irradiated to the twisted water outlet bar 103 and / or the water flow sprayed from the water outlet bar 103, and the combination of the light, the twisted water outlet bar 103, and the dancing water flow is conducive to improving the visual effect of the water outlet device 100 when the water is out of water.

[0045] Next, the driving assembly that can use the force of the water flow to drive the water spout 125 to move is introduced. In some embodiments, the driving assembly is used to drive the water spout 125 to rotate relative to the main body 101, and the rotation axis of the water spout 125 (i.e. Figure 5 The second axis 137 in the middle) and the central axis of the water outlet 138 (i.e. Figure 5 The angle between the first axis 136 in the water outlet 100 is an acute angle. In this way, when the water outlet 125 rotates, the water outlet strip 103 also rotates and thus twists. In addition, when the water outlet 125 and the water outlet strip 103 rotate, the end of the water flow can draw a circle on the user's skin, thereby increasing the spraying area of ​​the water outlet device 100 and providing the user with a massage feeling of water flow.

[0046] like Figure 4As shown, a second flow channel 134 is formed inside the main body 101. The second flow channel 134 is arranged between the water inlet 102 and the water outlet 138. Specifically, the chamber enclosed by the inclined water body 112, the water sealing cover 118 and the panel 126 and the inner cavity of the first seat body 105 together constitute the second flow channel 134. The cavity 133 located between the outer circumference of the first seat body 105 and the inner circumference of the embedded shell 104 will not have water passing through. The driving assembly includes the inclined water body 112, the impeller 115 and the deceleration mechanism. The inclined water body 112 is arranged in the second flow channel 134, for example, the inclined water body 112 can be slidably arranged inside the first seat body 105.

[0047] The matching relationship between the inclined water body 112 and the impeller 115 is as follows: Fig.11 As shown, the water body 112 is provided with a plurality of inclined water holes 144, the inclined water holes 144 and the impeller 115 are distributed along the axial direction of the impeller 115, the two ends of the inclined water holes 144 are distributed along the circumference of the impeller 115, and the impeller 115 is located downstream of the inclined water holes 144. Fig.11 For example, the inclined water hole 144 is located above the impeller 115, and the water inlet end (top end) of the inclined water hole 144 and the water outlet end (bottom end) of the inclined water hole 144 are spaced apart in the circumferential direction of the impeller 115. Figure 4 As shown, the impeller 115 is rotatably disposed in the second flow channel 134, specifically, the impeller 115 is located in a chamber surrounded by the inclined water body 112, the water sealing cover 118 and the panel 126. The top of the impeller 115 is fixedly connected to the rotating shaft of the generator 114, and the bottom of the impeller 115 is rotatably connected to the mounting shaft 142 of the panel 126. Fig.11 As shown, the blades 145 of the impeller 115 are in the shape of a flat plate, and the blades 145 are parallel to the rotation axis of the impeller 115. When water flows out from the inclined water hole 144, the water flow is inclined, and the force applied by the water flow to the blades 145 can be decomposed into a component force along the circumferential or tangential direction of the impeller 115, and the component force can drive the impeller 115 to rotate. The impeller 115 and the water outlet 125 are connected by a reduction mechanism. When the impeller 115 rotates, the water outlet 125 will also rotate. Under the action of the reduction mechanism, the rotation speed of the water outlet 125 is slower than that of the impeller 115, so that the movement speed of the water outlet 125 and the water outlet bar 103 can be appropriately reduced, so that the user can clearly see the twisting effect of the water outlet bar 103 and the dancing effect of the water flow.

[0048] like Fig.12As shown, in some embodiments, the speed reduction mechanism includes a first gear 146, a second gear 147, a driving column 149, a third gear 141 and a fourth gear 140, and the above four gears are all external gears. The first gear 146 is fixedly connected to the impeller 115, and the two can rotate synchronously. Since the water outlet device 100 includes a plurality of water outlet nozzles 125 and a plurality of water outlet bars 103, the fourth gear 140 is also provided with a plurality of ( Fig.12 Only one fourth gear 140 is shown), each fourth gear 140 is fixedly connected to a water outlet 125, and each water outlet 125 is connected to a water outlet bar 103. In this embodiment, the first gear 146 and the impeller 115 are connected in an integral manner (for example, the two are injection molded together), and the two together constitute a part. Similarly, the fourth gear 140 and the water outlet 125 are also fixed in an integral manner, and the two together constitute a part. In other embodiments, the first gear 146 and the impeller 115, and the fourth gear 140 and the water outlet 125 can also be fixed in a detachable manner. The second gear 147 is meshed with the first gear 146, and the drive column 149 is fixed to one of the end faces of the second gear 147. The rotation axis of the drive column 149 and the second gear 147 are spaced apart in the radial direction of the second gear 147. As shown Fig.13 As shown, the third gear 141 includes a plurality of driving grooves 150, which are straight and extend in the radial direction of the third gear 141, and the plurality of driving grooves 150 are distributed at intervals along the circumference of the third gear 141. The fourth gear 140 is meshed with the third gear 141, and the plurality of fourth gears 140 surround the third gear 141 together, and the rotation axis of the fourth gear 140 is the rotation axis of the water outlet 125.

[0049] The working principle of the above-mentioned speed reduction mechanism is described below. When the impeller 115 rotates continuously, the first gear 146 also rotates continuously, thereby driving the second gear 147 and the drive column 149 to rotate continuously. However, the third gear 141 does not rotate continuously. During the continuous rotation of the second gear 147 and the drive column 149, the distance between the rotation axis of the drive column 149 and the third gear 141 will change periodically, and the drive column 149 will periodically enter and leave the drive slot 150. When the drive column 149 is located in the drive slot 150 (such as Fig.15 and Fig.16 As shown in FIG. 1 ), the driving column 149 abuts against the wall of the driving slot 150, and the driving column 149 drives the third gear 141 to rotate. When the driving column 149 is outside the driving slot 150, the transmission connection between the second gear 147 and the third gear 141 is disconnected, and the second gear 147 and the driving column 149 cannot drive the third gear 141 to rotate (as shown in FIG. 1 ). Fig.14As shown in FIG. 1 ). Since the third gear 141 rotates intermittently, the fourth gear 140 and the water outlet 125 also rotate intermittently.

[0050] Please refer to Figures 14 to 16 In a specific embodiment, the third gear 141 includes six driving slots 150, and the angle between two adjacent driving slots 150 is 60°. The process of the second gear 147 rotating counterclockwise is as follows: Figures 14 to 16 As shown. Fig.14 In the initial state, after the second gear 147 rotates 60° counterclockwise, the driving column 149 enters one of the driving grooves 150 (such as Fig.15 Then, the driving column 149 drives the third gear 141 to rotate, and the driving column 149 gradually slides toward the outer end of the driving slot 150. Fig.16 After the state shown, as the second gear 147 and the driving column 149 rotate, the driving column 149 will gradually slide to the inner end of the driving groove 150 and leave the current driving groove 150. Next, as the second gear 147 and the driving column 149 continue to rotate, the driving column 149 will enter the next driving groove 150 in the next cycle. In this way, the driving column 149 will periodically enter and leave the driving groove 150, thereby eventually causing the water outlet 125 and the water outlet bar 103 to intermittently move.

[0051] like Fig.12 As shown, the speed reduction mechanism further includes a guide protrusion 148, the guide protrusion 148 and the driving column 149 are connected to the same end surface of the second gear 147, and the guide protrusion 148 is arc-shaped. The third gear 141 is provided with a guide arc surface 151 (such as Fig.13 As shown in FIG. 1 ), the guide arc surface 151 is matched with the guide protrusion 148, and a guide arc surface 151 is provided between every two adjacent driving grooves 150. Fig.14 As shown, when the driving column 149 is located outside the driving groove 150, the guide protrusion 148 is in contact with the guide arc surface 151. This arrangement can improve the transmission stability between the second gear 147 and the third gear 141.

[0052] In the above embodiment, since the third gear 141 rotates intermittently, the speed reduction ratio of the speed reduction mechanism is relatively high, and the speed reduction effect of the speed reduction mechanism is better. In other embodiments not shown in the figure, the speed reduction mechanism can also be set as a planetary speed reduction mechanism.

[0053] like Figure 5As shown, in some embodiments, the water outlet device 100 further includes a magnetic unit 123, and each fourth gear 140 is connected to a magnetic unit 123. The fourth gear 140 includes a mounting groove 139, the mounting groove 139 is connected to the water outlet 138 and the mounting groove 139 is located upstream of the water outlet 138, and the magnetic unit 123 is arranged in the mounting groove 139. In this way, water will pass through the magnetic unit 123 before flowing out of the water outlet 138. The magnetic force of the magnetic unit 123 can affect the growth rate of the crystal nucleus of the scale, thereby reducing the generation rate of the scale. Therefore, the arrangement of the magnetic unit 123 is conducive to softening the water quality. And installing the magnetic unit 123 in the mounting groove 139 of the fourth gear 140 is conducive to improving the compactness of the structure of the water outlet device 100. In some embodiments, the magnetic unit 123 may include two arc-shaped magnets, and the two arc-shaped magnets are spliced ​​together to form a circular magnetic unit 123, and water can pass through the hole in the center of the magnetic unit 123. In this way, even if the fourth gear 140 and the magnetic unit 123 rotate, the flow path of water when passing through the magnetic unit 123 and the fourth gear 140 is substantially the same.

[0054] In addition to the movement modes of the water outlet 125 described above, the water outlet 125 may also have other movement modes. For example, the water outlet 125 periodically swings relative to the main body 101, the swing axis is perpendicular to the central axis of the water outlet 138, and the extension direction of the swing axis is perpendicular to the radial direction of the main body 101. Accordingly, the movement trajectory of the end of the outlet water flow on the user's skin can be a straight line, which extends in the radial direction of the main body 101. For another example, the water outlet 125 can periodically reciprocate in the radial direction of the main body 101. The movement modes of the water outlet 125 are not listed here one by one.
