[0045] Figure 1 FIG. 1 shows a water outlet device 100 according to an embodiment of the present invention. Figure 2 and Figure 3 They are Figure 1 The cross-sectional view and the exploded view of the water outlet device 100 are shown in FIG. Figure 1 and Figure 2 As shown, the water outlet device 100 includes a main body 101, a driving assembly 107, a movable plate 115 and a water outlet 102. Figure 2 As shown, the main body 101 is provided with a water inlet 105, and the water outlet 102 is installed on the main body 101, and the water outlet 102 is provided with a water outlet 118. Water entering from the water inlet 105 can flow inside the main body 101, and the water flows through the drive assembly 107 and the water outlet 102 in sequence, and finally flows out from the water outlet 118. In this embodiment, the main body 101 includes a water inlet joint 112, a gland 116 and a panel 114, and the water inlet 105 is arranged on the water inlet joint 112. The water outlet device 100 also includes a connecting screw (such as Figure 3 As shown in FIG. 1 ), the connecting screws are used to fix the panel 114 and the water inlet joint 112, the gland 116 is clamped between the panel 114 and the water inlet joint 112, and the gland 116 is used to clamp the movable plate 115 together with the water inlet joint 112. A first sealing ring 113 is provided between the water inlet joint 112 and the panel 114.

[0046] like Figure 4 and Figure 5 As shown, the drive assembly 107 includes a mounting seat 110 and a movable rod 128. The mounting seat 110 is rotatably connected to the main body 101. For example, the mounting seat 110 is roughly cylindrical and is rotatably disposed inside the water inlet joint 112 (such as Figure 2 As shown in FIG. 1 ), a second sealing ring 111 is provided between the mounting seat 110 and the water inlet joint 112. The mounting seat 110 can rotate about a vertical axis, which can be the central axis of the mounting seat 110 itself. The movable rod 128 can reciprocate relative to the mounting seat 110. In this embodiment, the reciprocating motion of the movable rod 128 can be a reciprocating linear motion, that is, the movable rod 128 moves back and forth along a straight line. Figure 4 and Figure 5As shown, a straight guide groove 129 is provided at the bottom of the mounting seat 110, and a movable rod 128 is slidably disposed in the guide groove 129, and the movable rod 128 can perform reciprocating linear motion along the guide groove 129. In other embodiments not shown in the figure, the reciprocating motion of the movable rod 128 can also be set to swing. The method of driving the movable rod 128 to reciprocate relative to the mounting seat 110 will be described in detail below.

[0047] like Figure 2 As shown, in this embodiment, two movable plates 115 are provided, and the movable plates 115 are installed inside the main body 101. The movable plates 115 can reciprocate relative to the main body 101 under the drive of the movable rod 128. In addition, the movable plate 115 is connected to the water spout 102, and the water spout 102 can be driven by the movable plate 115 to swing relative to the main body 101. That is, the reciprocating movable rod 128 first drives the movable plate 115 to reciprocate, and the movable plate 115 then drives the water spout 102 to swing.

[0048] The mounting seat 110 can rotate relative to the main body 101 to change the reciprocating direction of the movable rod 128, thereby changing the swing direction and / or swing amplitude of the water outlet 102. In this way, the water flow dancing direction and / or the degree of water flow dancing of the water outlet device 100 can be adjusted, and the water flow effect of the water outlet device 100 is highly adjustable.

[0049] The “reciprocating motion direction of the movable rod 128” refers to the arrangement direction of the two extreme positions that the movable rod 128 can reach when the movable rod 128 reciprocates. Figure 5 For example, the movable rod 128 can move from the leftmost end to the rightmost end of the guide slot 129. The two ends of the guide slot 129 are the two extreme positions of the movable rod 128. The two extreme positions of the movable rod 128 are arranged along the left-right direction. At this time, the reciprocating direction of the movable rod 128 is the left-right direction. Figure 5 On the basis of the above, the mounting base 110 is rotated 90°, so that the guide groove 129 becomes extended in the front-to-back direction, and the reciprocating direction of the movable rod 128 becomes the front-to-back direction. Similarly, the "swing direction of the water spout 102" can be the arrangement direction of the two extreme positions that the swing end of the water spout 102 can reach. The "swing amplitude of the water spout 102" can be the angle between the two extreme positions that the swing end of the water spout 102 can reach.

[0050] The following first describes how the movable rod 128 of the driving assembly 107 is driven.

[0051] like Figure 6As shown, the driving assembly 107 includes an impeller 109, and the impeller 109 includes a plurality of blades 151. The blades 151 may be flat and vertically arranged. The impeller 109 is rotatably connected to the mounting seat 110. Figure 2 As shown, the driving assembly 107 further includes a pin 108, which is inserted into the impeller 109 and connected to the water inlet connector 112 of the main body 101. The central axis of the pin 108 is the rotation axis of the impeller 109. Figure 2 As shown, the water inlet connector 112 of the main body 101 is provided with a plurality of inclined water holes 106, and the inclined water holes 106 are located downstream of the water inlet 105 and upstream of the impeller 109, and the plurality of inclined water holes 106 are together surrounding the rotation axis of the impeller 109. The inclined water holes 106 are inclined, specifically, the inclined water holes 106 and the impeller 109 are distributed along the axial direction of the impeller 109, and the two ends of the inclined water holes 106 are distributed along the circumference of the impeller 109. For example, the inclined water holes 106 are located above the impeller 109, and the upper end and the lower end of the inclined water holes 106 are staggered from each other. In this way, the water flowing out of the inclined water holes 106 will contact the impeller 109, and the force applied by this water flow to the blades 151 has a component force along the circumference of the impeller 109, and this component force can drive the impeller 109 to rotate.

[0052] like Figure 8 As shown, the driving assembly 107 also includes a first inner gear ring 135 and a first outer gear 127 that mesh with each other. The first inner gear ring 135 is fixedly connected to the mounting seat 110, and the two can be integrally formed or separately arranged. The impeller 109 is transmission-connected to the first outer gear 127, and when the impeller 109 rotates, the first outer gear 127 will also rotate. The movable rod 128 is fixedly connected to one of the end faces of the first outer gear 127, for example, the movable rod 128 is connected to the bottom end face of the first outer gear 127. The movable rod 128 and the first outer gear 127 can be integrally formed or separately arranged. The movable rod 128 is eccentrically arranged relative to the first outer gear 127, and the central axis of the movable rod 128 (i.e., the fourth axis 152) is parallel to the central axis of the first outer gear 127 (i.e., the third axis 132). As described above, the mounting seat 110 is provided with a guide groove 129, and the movable rod 128 is slidably arranged in the guide groove 129. As Fig.10 As shown, the guide groove 129 is straight and extends in the radial direction of the first internal gear ring 135 .

[0053] The process of the swing of the movable rod 128 is as follows Fig.10 As shown, with the impeller 109 ( Fig.10When the first outer gear 127 (not shown) rotates, the first outer gear 127 will also rotate. When the first outer gear 127 rotates, the first outer gear 127 will both revolve and rotate. Revolve refers to the rotation of the first outer gear 127 around the center of the first inner gear ring 135, and rotate refers to the rotation of the first outer gear 127 around its own center. During the rotation of the first outer gear 127, the movable rod 128 will also rotate around the center of the first outer gear 127, and due to the constraint of the guide groove 129, the movable rod 128 will move back and forth along the guide groove 129. In this way, if water enters the water outlet device 100, the water flow will push the impeller 109 to rotate, thereby causing the movable rod 128 to move back and forth. There is no need to set a power element such as a motor in the water outlet device 100, and the cost of the water outlet device 100 is relatively low. In addition, the guide groove 129 can not only guide the movable rod 128, but also allow water to pass through so that the water leaves the drive assembly 107. Figure 2 As shown, water can flow through the water inlet 105, the inclined water hole 106, the guide groove 129 and the water outlet 102 in sequence.

[0054] In some embodiments, the driving assembly 107 further includes a speed reduction mechanism, and the impeller 109 and the first outer gear 127 are connected in transmission via the speed reduction mechanism. The speed reduction mechanism can prevent the first outer gear 127 from rotating too fast, thereby preventing the reciprocating speed of the movable rod 128 from being too fast, and further preventing the water outlet 102 from swinging too fast. Slowing down the swinging speed of the water outlet 102 can prevent the dancing speed of the water flow from being too fast, thereby ensuring that the user can observe the dancing effect of the water flow.

[0055] like Figure 6 As shown, the speed reduction mechanism includes a second inner gear ring 123, a third inner gear ring 124, a second outer gear 121, a third outer gear 122 and a connecting rod 125. The second inner gear ring 123 is fixedly connected to the mounting seat 110, and the third inner gear ring 124 is rotatably connected to the mounting seat 110. The third inner gear ring 124, the second inner gear ring 123 and the impeller 109 are coaxially arranged, and the central axes of the three are all the first axis 130. The second outer gear 121 is meshed with the second inner gear ring 123, and the second outer gear 121 is fixedly connected to the impeller 109. The second outer gear 121 and the third outer gear 122 are fixedly connected. In this embodiment, the two are integrally formed, and the second outer gear 121 and the third outer gear 122 are equivalent to jointly forming a double gear; in other embodiments, the second outer gear 121 and the third outer gear 122 can be separately arranged. The second external gear 121 and the third external gear 122 are coaxially arranged, and the central axis of the two is the second axis 131. The second external gear 121 and the third external gear 122 are eccentrically arranged relative to the impeller 109. The matching manner of the second external gear 121 and the second internal gear ring 123 is as follows: Fig. 9 As shown, from Fig. 9It can be seen that the second outer gear 121 is eccentrically arranged relative to the second inner gear ring 123. Similarly, the third outer gear 122 is also eccentrically arranged relative to the third inner gear ring 124. The number of teeth of the second outer gear 121 is less than the number of teeth of the second inner gear ring 123, and the difference in the number of teeth between the two can be 1 to 4. The number of teeth of the third outer gear 122 is less than the number of teeth of the third inner gear ring 124, and the difference in the number of teeth between the two can be 1 to 4. The third outer gear 122 is meshed with the third inner gear ring 124. One end of the connecting rod 125 is fixed to the third outer gear 122, and the first outer gear 127 is rotatably mounted on the other end of the connecting rod 125. Specifically, as Figure 7 and Figure 8 As shown, the connecting rod 125 includes a first shaft portion 133 and a second shaft portion 134, the first shaft portion 133 and the second shaft portion 134 are staggered with each other, and the inner cylinder 126 (as shown in FIG. Figure 3 The first shaft portion 133 is fixed to the third inner gear ring 124, and the first outer gear 127 is rotatably sleeved on the outer periphery of the second shaft portion 134. The transmission mode of the speed reduction mechanism is a planetary gear transmission with a small tooth difference, and the speed reduction ratio of the speed reduction mechanism is relatively large and the structure is compact.

[0056] In other embodiments not shown in the figures, the transmission mode of the reduction mechanism can also be set to planetary gear transmission, worm gear transmission, multi-stage gear transmission, etc.

[0057] like Figure 4 As shown, the driving mechanism further includes a lever 103, one end of which is fixedly connected to the mounting seat 110, and the other end of which is exposed outside the main body 101 (eg, Figure 1 As shown). The lever 103 facilitates the user to adjust the swing amplitude and / or swing direction of the water spout 102. The user can move the end of the lever 103 exposed outside the mounting seat 110, so that the mounting seat 110 rotates relative to the body 101, thereby changing the reciprocating direction of the movable rod 128 and the swing direction of the water spout 102. The lever 103 and the mounting seat 110 can be connected by screw connection, clamping connection, magnetic connection, etc. Figure 1 As shown, the main body 101 is further provided with an arc-shaped avoidance groove 104 , and the lever 103 passes through the avoidance groove 104 to the outside of the main body 101 , and the two ends of the avoidance groove 104 can also limit the lever 103 .

[0058] The following will introduce how the lever 103 drives the movable plate 115 to move and how the movable plate 115 drives the water spout 102 to move.

[0059] like Fig.11As shown, the water outlet device 100 includes two mutually stacked movable plates 115, the two movable plates 115 are respectively a first movable plate 119 and a second movable plate 120, the first movable plate 119 can reciprocate along a first direction relative to the main body 101, and the second movable plate 120 can reciprocate along a second direction relative to the main body 101. The first direction and the second direction intersect, and either the first direction and the second direction is perpendicular to the stacking direction of the movable plates 115. "The first direction and the second direction intersect" means that the two directions are not parallel or overlapped, and the angle between the two directions can be an acute angle, a right angle, or an obtuse angle. If Fig.11 For example, the first direction is the front-rear direction, the second direction is the left-right direction, and the stacking direction is the top-bottom direction.

[0060] When the movable rod 128 reciprocates along the first direction, the movable rod 128 can drive the first movable plate 119 to reciprocate along the first direction, so that the water spout 102 swings along the first direction (i.e., the water spout 102 swings back and forth). At this time, the movable rod 128 does not drive the second movable plate 120 to move, and the second movable plate 120 does not drive the water spout 102 to move.

[0061] When the movable rod 128 reciprocates in the second direction (i.e., the water spout 102 swings left and right), the movable rod 128 drives the second movable plate 120 to reciprocate in the second direction, so that the water spout 102 swings in the second direction. At this time, the movable rod 128 does not drive the first movable plate 119 to move, and the first movable plate 119 does not drive the water spout 102 to move.

[0062] In this way, by changing the reciprocating direction of the movable rod 128 , the movable plate 115 driven by the movable rod 128 can be changed, thereby changing the swinging direction of the water spout 102 .

[0063] Fig.12 and Fig.13 The figure shows the state where two movable plates 115 are stacked on each other. Fig.12 is a top view, Fig.13 This is a bottom view. Fig.12 In the embodiment, the first movable plate 119 covers a portion of the second movable plate 120. Fig.13 In the embodiment, the second movable panel 120 covers a portion of the first movable panel 119 .

[0064] like Fig.12 As shown, the first movable plate 119 includes two first abutting portions 144 spaced apart along the first direction. After the water outlet device 100 is assembled, the movable rod 128 is located between the two first abutting portions 144 ( Fig.12 The movable rod 128 is not shown. The distance between the two first abutting portions 144 in the first direction is L1 (eg Fig.12As shown in the figure, the movable rod 128 makes a reciprocating linear motion relative to the mounting base 110. The movement amplitude of the movable rod 128 is D0, and L1 < D0. The movement amplitude of the movable rod 128 refers to: in the reciprocating movement direction of the movable rod 128, the maximum distance between the two extreme positions of the movable rod 128. For example, in Fig.16 Figure, position C1 and position C2 are respectively the two extreme positions of the movable rod 128, and the distance between the rear end of position C1 and the front end of position C2 is D0. Since L1 < D0, when the movable rod 128 reciprocates in the first direction, the movable rod 128 will periodically push the two first abutting portions 144, so that the first movable plate 119 reciprocates in the first direction. For example, during the process of the movable rod 128 moving from C1 to C2, the movable rod 128 pushes the first movable plate 119 forward; during the process of the movable rod 128 moving from C2 to C1, the movable rod 128 pushes the first movable plate 119 backward.

[0065] Similarly, as Fig.12 shown, the second movable plate 120 includes two second abutting portions 146 that are spaced apart in the second direction, and the movable rod 128 will be located between the two second abutting portions 146 ( Fig.12 the movable rod 128 is not shown). The distance between the two second abutting portions 146 in the second direction is L2 (as Fig.12 shown), and L2 < D0. In this way, as Fig.14 shown, when the movable rod 128 reciprocates in the second direction, the two extreme positions of the movable rod 128 are A1 and A2 respectively, and the movable rod 128 will periodically push the two second abutting portions 146, so that the second movable plate 120 reciprocates in the second direction.

[0066] Please refer to Figures 11 to 13 Figure, the first movable plate 119 includes a first through hole 136, the second movable plate 120 includes a second through hole 139, and the first through hole 136 and the second through hole 139 are connected. The hole wall of the first through hole 136 includes the above-mentioned first abutting portion 144, and the hole wall of the second through hole 139 includes the above-mentioned second abutting portion 146. The movable rod 128 passes through the first through hole 136 and the second through hole 139. In this way, the movable rod 128 can cooperate with both the first abutting portion 144 and the second abutting portion 146.

[0067] As Fig.13As shown, the hole wall of the first through hole 136 also includes two first avoidance portions 145 spaced apart along the second direction, and in the second direction, the two second abutment portions 146 are both located between the two first avoidance portions 145. The distance between the two first avoidance portions 145 in the second direction is W1, and W1>D0. In this way, when the movable rod 128 reciprocates along the second direction, although the movable rod 128 can push the second abutment portion 146, the movable rod 128 cannot push the first avoidance portion 145, thereby ensuring that the second movable plate 120 is stationary at this time.

[0068] Similarly, if Fig.13 As shown, the hole wall of the second through hole 139 also includes two second avoidance portions 147 spaced apart along the first direction, and in the first direction, the two first abutment portions 144 are both located between the two second avoidance portions 147. The distance between the two second avoidance portions 147 in the first direction is W2, and W2>D0. In this way, when the movable rod 128 reciprocates along the first direction, although the movable rod 128 can push the first abutment portion 144, the movable rod 128 cannot push the second avoidance portion 147, thereby ensuring that the second movable plate 120 is stationary at this time.

[0069] like Fig.11 and Fig.12 As shown, the first movable plate 119 includes a first driving hole 137, and the length of the first driving hole 137 in the first direction is less than the length of the first driving hole 137 in the second direction. Fig.11 and Fig.13 As shown, the second movable plate 120 includes a second drive hole 140, and the length of the second drive hole 140 in the second direction is less than the length of the second drive hole 140 in the first direction. More specifically, the first drive hole 137 can be a waist-shaped hole extending in the left-right direction, and the second drive hole 140 can be a waist-shaped hole extending in the front-rear direction.

[0070] Any water outlet 102 satisfies the following conditions: the water outlet 102 is passed through a first driving hole 137 and a second driving hole 140; the water outlet 102 can slide in the first driving hole 137 along the second direction; and the water outlet 102 can slide in the second driving hole 140 along the first direction; the end walls of the first driving hole 137 in the first direction are used to abut against the water outlet 102; and the end walls of the second driving hole 140 in the second direction are used to abut against the water outlet 102.

[0071] To put it more intuitively, please combine Figures 11 to 13, a first driving hole 137 and a second driving hole 140 corresponding to each other are cross-intersecting, and the water spout 102 is arranged in the intersection area of ​​the two driving holes. When the first movable plate 119 reciprocates back and forth, the front wall surface and the rear wall surface of the first driving hole 137 push the water spout 102 to swing back and forth, and the water spout 102 will also slide back and forth in the second driving hole 140 when swinging. When the second movable plate 120 reciprocates left and right, the left wall surface and the right wall surface of the second driving hole 140 push the water spout 102 to swing left and right, and the water spout 102 will also slide left and right in the first driving hole 137 when swinging.

[0072] like Fig.11 As shown, the water outlet 102 includes a columnar portion 142 and a ball head 143. The columnar portion 142 is inserted into the first drive hole 137 and the second drive hole 140. The ball head 143 is rotatably disposed in a ball socket (not shown) of the main body 101. The outer periphery of the ball head 143 may also be provided with a third sealing ring 117 (as shown in FIG. Figure 2 ). The hole wall of the first driving hole 137 and the hole wall of the second driving hole 140 are used to push the columnar portion 142, so that the water spout 102 swings around the ball head 143, thereby changing the direction of the water outlet 118 of the water spout 102. The swing end of the water spout 102 is actually the top of the columnar portion 142. In this way, the water spout 102 can be driven to swing by the movement of the movable plate 115.

[0073] like Fig.11 As shown, the first movable plate 119 includes a first guide hole 138, and the second movable plate 120 includes a second guide hole 141. The main body 101 includes a guide portion 148 (such as Fig.14 As shown in the figure, any one of the guide parts 148 satisfies: the guide part 148 is inserted into a first guide hole 138 and a second guide hole 141, and the guide part 148 can slide in the first guide hole 138 along the first direction, and slide in the second guide hole 141 along the second direction. The first guide hole 138 and the second guide hole 141 can both be set as waist-shaped holes, and the first guide hole 138 and the second guide hole 141 are cross-shaped, and the guide part 148 can be a columnar protrusion. The guide part 148 is used to guide the movement of the first movable plate 119 and the second movable plate 120.

[0074] In some embodiments, when the movable rod 128 reciprocates along the third direction, the first movable plate 119, the second movable plate 120 and the water spout 102 are all stationary. Here, stationary means no reciprocating motion, and the stationary state of the water spout 102 is equivalent to the swing amplitude of the water spout 102 becoming 0. The third direction is perpendicular to the stacking direction, and either the first direction or the second direction intersects with the third direction. For example, Fig.12As shown, the included angle between the third direction and the first direction is 45°. Such a setting can improve the adjustability of the swinging effect of the water outlet nozzle 102.

[0075] The following describes how to implement the above functions. When observing along the stacking direction (i.e., the direction perpendicular to the Fig.12 paper surface of the figure), the pore walls of the first through hole 136 and the second through hole 139 intersect to form four intersection points. For two intersection points on the same diagonal, the distance between the two intersection points is L3, and L3 > D0. As Fig.15 shown, when the movable rod 128 reciprocates along the third direction, the two extreme positions of the movable rod 128 are B1 and B2 respectively. Since L3 > D0, at this time, the movable rod 128 can neither contact the first abutting portion 144 nor the second abutting portion 146, neither the first movable plate 119 nor the second movable plate 120 moves, and the water outlet nozzle 102 is stationary.

[0076] In some other embodiments, the water outlet device 100 can also be set such that when the movable rod 128 reciprocates along the third direction, the movable rod 128 drives both the first movable plate 119 to reciprocate along the first direction and the second movable plate 120 to reciprocate along the second direction, so as to make the water outlet nozzle 102 reciprocate along the third direction. Such a setting can also improve the adjustability of the swinging effect of the water outlet nozzle 102.

[0077] For example, as Fig.18 shown, the pore wall of the first through hole 136 further includes a first connecting portion 149. The first connecting portion 149 is inclined relative to both the first direction and the second direction. A first connecting portion 149 is provided between an adjacent first abutting portion 144 and a first avoiding portion 145. The distance between two relatively arranged first connecting portions 149 is D1, and D1 < D0. The arrangement direction of the two relatively arranged first connecting portions 149 is denoted as the third direction. Then, when the movable rod 128 reciprocates along the third direction, the movable rod 128 will periodically push the two first connecting portions 149. Since the guiding portion 148 abuts against the left and right end walls of the first guiding hole 138, the first movable plate 119 cannot move along the second direction, and the acting force exerted by the movable rod 128 on the first connecting portion 149 will drive the first movable plate 119 to reciprocate along the first direction.

[0078] Similarly, the hole wall of the second through hole 139 further includes a second connecting portion 150. The second connecting portion 150 is inclined relative to both the first direction and the second direction. A second connecting portion 150 is provided between an adjacent second abutting portion 146 and a second avoiding portion 147. The distance between two relatively arranged second connecting portions 150 is D2, and D2 < D0. The arrangement direction of the two relatively arranged second connecting portions 150 is also the third direction. After the first movable plate 119 and the second movable plate 120 are stacked on top of each other, the second connecting portion 150 coincides with the first connecting portion. When the movable rod 128 reciprocates in the third direction, the movable rod 128 periodically pushes the two second connecting portions 150, so that the second movable plate 120 reciprocates in the second direction.

[0079] Since the first movable plate 119 and the second movable plate 120 reciprocate simultaneously, the movement of the water outlet nozzle 102 can be decomposed into two component movements. One of the component movements is forward and backward swinging, and the other component movement is left and right swinging. After the two component movements are superimposed, the water outlet nozzle 102 actually swings in the third direction.

[0080] In some embodiments, the first direction is perpendicular to the second direction. The first abutting portion 144 extends straight along the second direction, and the second abutting portion 146 extends straight along the first direction. Such an arrangement can reduce the shape complexity of the first through hole 136 and the second through hole 139, thereby reducing the processing difficulty of the movable plate 115. To further reduce the shape complexity of the first through hole 136 and the second through hole 139, the first avoiding portion 145, the second avoiding portion 147, the first connecting portion 149, and the second connecting portion 150 can all be straight. The movement amplitude of the movable rod 128 is constant. In this way, when the movable rod 128 only drives one movable plate 115 to move, as the reciprocating movement direction of the movable rod 128 changes, the reciprocating movement amplitude of the movable plate 115 also changes. That is, changing the reciprocating movement direction of the movable rod 128 can change the reciprocating movement amplitude of the water outlet nozzle 102.

[0081] Taking the second movable plate 120 as an example, when the movable rod 128 reciprocates in the second direction, the second movable plate 120 reciprocates in the second direction. However, conversely, in order to make the second movable plate 120 reciprocate in the second direction, the movable plate 115 does not have to strictly reciprocate in the second direction. For example, when the lever 103 switches from the Fig.14 position shown to the Fig.17 angle shown, the lever 103 rotates counterclockwise by about 20°. At this time, the movable rod 128 can still push the second movable plate 120 to move. Therefore, based on the Fig.14 state shown, when the lever 103 rotates counterclockwise by an angle less than 45°, the movable rod 128 can push the second movable plate 120 to move.

[0082] like Fig.17 As shown, at this time, the two extreme positions of the movable rod 128 are E1 and E2 respectively. Although the reciprocating amplitude of the movable rod 128 is still D0, the projection component of D0 in the second direction decreases (the projection component is still greater than L2), the distance the second movable plate 120 is pushed decreases, the reciprocating amplitude of the second movable plate 120 decreases, and the swing amplitude of the water outlet 102 also decreases.

[0083] Similarly, Fig.14 Based on the state shown in FIG. 1 , when the lever 103 rotates counterclockwise at an angle greater than 45° and less than 90°, as long as the projection component of D0 in the first direction is greater than L1, the movable rod 128 can push the first movable plate 119 to move; however, as the reciprocating motion direction of the movable rod 128 changes, the reciprocating motion amplitude of the first movable plate 119 and the swing amplitude of the water spout 102 will also change. It should be noted that the lever 103 can continuously rotate from 0° to 90° (i.e., from Fig.14 The angle shown switches to Fig.16 and stay at any angle in the above angle range.

[0084] In other embodiments not shown, the number of movable plates 115 of the water outlet device 100 may be greater than two. For example, the water outlet device 100 further includes a third movable plate 115. When the movable rod 128 reciprocates along the third direction, the third movable plate 115 is driven, and the third movable plate 115 drives the water outlet 102 to swing along the third direction. Alternatively, in other embodiments not shown, the water outlet device 100 may also include only one movable plate 115. For example, the first abutting portion 144 and the second abutting portion 146 are both disposed on the only movable plate 115, and the first abutting portion 144 and the second abutting portion 146 are wall surfaces on different sides of the same through hole.
