[0054] The technical solution of this embodiment will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0055] As Figures 1 - 20 shown, this embodiment provides a multi-functional switching element, including a driving member 10, a rotating rod 20 and a plurality of movable rods 30. The driving member 10 is sleeved on the rotating rod 20 and can drive the rotating rod 20 to rotate relative to the movable rods 30 with the axis of the rotating rod 20 as the axis. The plurality of movable rods 30 are respectively engaged with the rotating rod 20 to block or open a plurality of water channel passages; the driving member 10 has at least an adjustment position and a closed position. When the driving member 10 is toggled to any adjustment position, one of the plurality of water channel passages is opened and the others are closed. When the driving member 10 is toggled to the closed position, all the plurality of water channel passages are closed.

[0056] On the other hand, a water outlet device includes a multi-functional switching element, an adapter 60, a water outlet member 70, a water inlet member 80 and a housing 100. One end of the adapter 60 is connected to the multi-functional switching element, and the other end is connected to the water outlet member 70. The water inlet member 80 is connected to the other end of the multi-functional switching element. The housing 100 is sleeved outside the multi-functional switching element, the adapter 60, the water outlet member 70 and the water inlet member 80, and both the water outlet member 70 and the water inlet member 80 are screwed to the housing 100. The driving member 10 of the multi-functional switching element extends out of the housing 100.

[0057] Specifically, the use of the driving member 10 in this embodiment can facilitate the user to operate simply. The synchronous rotation of the rotating rod 20 can be achieved by toggling the driving member 10, and the meshing connection between the rotating rod 20 and the movable rod 30 can be used to realize the opening and closing of different water channels, and complete the water channel switching. At the same time, the driving member 10 is provided with an adjustment position and a closing position. When the driving member 10 is toggled to any adjustment position, one of the several water channels is opened, and the other channels are in a closed state, thereby realizing the switching between different water channels. When the driving member 10 is toggled to the closing position, all water channels are closed, thereby increasing the closing function. At the same time, the adjustment by the driving member 10 not only has a small rotation angle, reduces the operation range, but also has a simple structure, labor-saving operation, reduces the cost of the product, and is suitable for spray guns with different water discharge effects. Accordingly, the water outlet device provided with a multifunctional switching element can realize the complete spraying of two water channels, so as to realize the labor-saving switching of the water channels through simple operation at high and low pressures, and close multiple water channels at the same time to save water sources.

[0058] The specific structure of the multifunctional switching element in this embodiment is described below.

[0059] Combination Figure 1 , Figures 3 - 9 As shown, the multifunctional switching element in this embodiment includes a driving member 10, a rotating rod 20, an active rod 30, a waterway assembly 40 and a positioning member 50. Optionally, in this embodiment, the driving member 10 is sleeved on the rotating rod 20, and can drive the rotating rod 20 to rotate relative to the active rod 30 with the axis of the rotating rod 20 as the axis. At the same time, there are a plurality of active rods 30, and the plurality of active rods 30 are all engaged with the rotating rod 20, so that when the rotating rod 20 rotates in different directions, the corresponding active rods 30 can be driven to rotate, so that different waterway channels can be opened or blocked to achieve waterway switching. Further, in this embodiment, the driving member 10 has at least an adjustment position and a closing position, and the adjustment position is set corresponding to the waterway channel, so that when the driving member 10 is moved from the closing position to any adjustment position, one of the plurality of waterway channels is opened, and the other channels remain closed. When switching to other adjustment positions, the opening and closing of the waterway channels are interchanged, so as to achieve waterway switching. Specifically, when the driving member 10 is moved to the closed position, all water channels are closed, so that the water outlet is closed through the multifunctional switching element when the user is not in use.

[0060] For example, in this embodiment, two movable rods 30 are provided, and two corresponding water channels are also provided, and the movable rods 30, the water channels and the adjustment positions are provided in a one-to-one correspondence, so as to ensure that when the user pushes the driving member 10 to any adjustment position, the corresponding movable rod 30 moves and opens the water channel. Specifically, there are two adjustment positions, and the closed position is located between the two adjustment positions, so that the two water channels can transition through the closed position when switching, thereby improving the user experience.

[0061] Optionally, in this embodiment, the rotating rod 20 and the movable rod 30 are both rotatably disposed in the waterway assembly 40, and the rotating rod 20 can extend from the waterway assembly 40 to be connected to the driving member 10. Further, one end of the movable rod 30 is movably disposed in the waterway assembly 40, and the other end is movably disposed in the positioning member 50, and the positioning member 50 is engaged with the waterway assembly 40, so as to ensure the stable placement of the movable rod 30, so that it can rotate in the waterway assembly 40 and the positioning member 50 under the drive of the rotating rod 20, and the movable rod 30 can also move up and down along its axial direction to realize the opening and closing of the two waterway channels.

[0062] Combination Figure 1 and Figure 4 As shown, in this embodiment, the driving member 10 includes a toggle portion 11 and a connecting portion 12, and the toggle portion 11 is provided with an operating inclined surface, and the connecting portion 12 is provided with a connecting hole. Optionally, two operating inclined surfaces are provided at an angle on the toggle portion 11, so that the user can toggle the driving member 10 through the operating inclined surface, and the operation is simple. Specifically, one end of the connecting portion 12 is connected to the bottom of the toggle portion 11, and the other end is sleeved on the rotating rod 20. Optionally, in this embodiment, a connecting hole is provided through the connecting portion 12, and the rotating rod 20 is provided through the connecting hole, and the driving member 10 and the rotating rod 20 cannot rotate relative to each other, so that the rotating rod 20 can be driven to rotate synchronously when the driving member 10 is toggled. Exemplarily, the connecting hole is set in a non-circular shape and is provided with a first positioning plane, and the part where the rotating rod 20 is connected to the driving member 10 is adapted to its shape, and the two are limited and fixed by the first positioning plane to ensure stable insertion, and the two can only move axially, but not rotate circumferentially. In other embodiments, the shapes of the two may also be set to quadrilateral, hexagon or other special shapes, which are not limited here.

[0063] like Figure 1 , Figures 4 - 10As shown in the figure, in this embodiment, the rotating rod 20 includes a first rod body 21, a first base body 22, and a switching gear 23. A second positioning plane 211 and a stepped surface 212 are provided on the first rod body 21, and a seal 201 is sleeved on the first rod body 21. Optionally, the first base body 22 is cylindrical, the first rod body 21 is arranged above the first base body 22 along the axis direction of the first base body 22, the switching gear 23 is arranged on the side surface of the first base body 22, and the first rod body 21, the first base body 22, and the switching gear 23 form an L-shaped structure. Optionally, the driving member 10 is sleeved on the first rod body 21, and the shape of the connecting hole is adapted to the shape of the first rod body 21. The first positioning plane and the second positioning plane 211 are slidably arranged, thereby ensuring their stable connection. With the cooperation of the first positioning plane and the second positioning plane 211, the driving member 10 can only move along the axial direction of the first rod body 21 on the first rod body 21 and cannot rotate relative to the first rod body 21.

[0064] Furthermore, the second positioning plane 211 extends along the axis direction of the first rod body 21, and the stepped surface 212 extends along the radial direction of the first rod body 21, that is, the second positioning plane 211 and the stepped surface 212 are perpendicular to each other and form an L-shaped step. Specifically, the driving member 10 is limited above the stepped surface 212 to limit the moving range of the driving member 10 on the first rod body 21. Exemplarily, the seal 201 is sleeved on the first rod body 21 and is located between the driving member 10 and the first base body 22, and in this embodiment, the seal 201 is set as an umbrella-shaped sealing ring.

[0065] Specifically, the switching gear 23 is arranged on the side surface of the first base body 22, and the switching gear 23 is an incomplete gear, thereby avoiding occupying too much space and being able to drive any one of the movable rods 30 one by one by toggling in the opposite direction as needed. In other embodiments, the meshing length of the switching gear 23 can also be adjusted to realize driving two movable rods 30 at the same time. The two move in opposite directions at the same time, thereby changing the rotation direction of the driving member 10, then swapping the moving directions of the two, and further realizing the switching of two waterways. The specific adjustment method can be set as needed and will not be elaborated here. Exemplarily, in this embodiment, the switching gear 23 meshes with the movable rod 30, and when the driving member 10 is toggled and drives the rotating rod 20 to rotate synchronously with it, the movable rod 30 can move up and down along its axis while rotating to close and open the corresponding waterway, which is convenient for the user to adjust.

[0066] Such as Figures 4 - 9 、 Figure 11As shown in the figure, in this embodiment, the movable rod 30 includes a second base body 31 and a second rod body 32. A gear portion 311 and a lifting portion 312 are provided on the second base body 31, and a lifting inclined surface 301 is provided on the lifting portion 312. Specifically, the second base body 31 is provided in a cylindrical shape. In this embodiment, the second rod body 32 is arranged above the second base body 31 along the axis direction of the second base body 31. Further, the gear portion 311 is an incomplete gear, and the gear portions 311 on the two movable rods 30 are respectively located on both sides of the switching gear 23 and can be engaged with the switching gear 23. Thus, driven by the switching gear 23, the rotations of the two gear portions 311 can be realized separately or simultaneously, and further the separate or simultaneous rotations of the two movable rods 30 can be realized. In this embodiment, the two gear portions 311 are respectively engaged with the switching gear 23 to realize their respective separate rotations and complete the on-off of the corresponding water channels. Exemplarily, the height of the gear portion 311 is greater than the height of the switching gear 23, and the height of the gear portion 311 is adapted to the moving range of the movable rod 30. Thus, when the movable rod 30 moves up and down along its axis, it can still ensure that the gear portion 311 is engaged with the switching gear 23 without falling off. Exemplarily, a lifting portion 312 is provided on the back side of the gear portion 311, and the lifting portion 312 protrudes from the side surface of the second base body 31, and a spirally rising lifting inclined surface 301 is provided on its top surface. Optionally, the lifting inclined surface 301 is arranged towards the second rod body 32, and its height gradually increases near the second rod body 32. Specifically, the two movable rods 30 are arranged oppositely, that is, the two lifting inclined surfaces 301 are arranged facing each other. Thus, the respective upward and downward movements of the two movable rods 30 can be realized by rotating the rotating rod 20 in different directions, or in other embodiments, the two movable rods 30 can be made to move in opposite directions simultaneously.

[0067] As Figure 1 and Figure 11 shown, further, first limiting grooves 302 and second limiting grooves 303 are respectively provided at the upper and lower ends of the second base body 31 of the movable rod 30, and a first sealing ring 304 is arranged in the first limiting groove 302, and a second sealing ring 305 is arranged in the second limiting groove 303, thereby ensuring the sealing of the upper and lower parts of the movable rod 30. Exemplarily, both the first sealing ring 304 and the second sealing ring 305 are made of corrosion-resistant rubber materials, so as to ensure stable sealing and avoid damage to the inner wall of the channel when the movable rod 30 moves up and down.

[0068] As Figure 1 、 Figures 3 - 9 and Figures 12 - 14As shown, in this embodiment, the water channel assembly 40 is provided with a first inner cavity 401, a first channel 402, a second channel 403, a through hole 404, a sealing groove 405 and a third limiting groove 409, and the axial direction of the water channel assembly 40 is set to a first direction. Optionally, in this embodiment, the rotating rod 20 and the movable rod 30 are both rotatably arranged in the first inner cavity 401, and the first rod body 21 is sequentially arranged in the sealing groove 405 and the through hole 404 to extend out of the water channel assembly 40 to connect with the driving member 10. Figure 12 and Figure 13 As shown, the first channel 402, the second channel 403 and the through hole 404 are all connected to the first inner cavity 401, and the two movable rods 30 are respectively movably arranged in the first channel 402 and the second channel 403, and can move along the first direction in the first channel 402 and the second channel 403, thereby being able to respectively separate or connect the first channel 402 and the first inner cavity 401, and the second channel 403 and the first inner cavity 401, thereby realizing the connection and disconnection of the two water channels.

[0069] Correspondingly, one side of the sealing groove 405 is connected to the through hole 404, and the other side is connected to the first inner cavity 401. The sealing groove 405 and the through hole 404 are both arranged between the first channel 402 and the second channel 403, and the inner diameter of the sealing groove 405 is larger than the inner diameter of the through hole 404, so that the sealing member 201 can be limited in the sealing groove 405 after being sleeved on the first rod body 21. Specifically, in this embodiment, the sealing member 201 is an umbrella-shaped sealing ring, and its closed side is close to the bottom of the sealing groove 405, and the open side is arranged toward the first inner cavity 401, so that the first inner cavity 401 is not connected with the through hole 404 to avoid leakage. Figure 13 As shown, a third limiting groove 409 is provided on the outer side of the top of the two channels in the water channel assembly 40 for placing a third sealing ring to perform sealing and prevent leakage.

[0070] Combination Figure 13 and Figure 14 As shown, the inner wall of the waterway assembly 40 is also provided with a guide slope 406, a guide block 407 and a protrusion 408. Optionally, the guide slope 406 is spirally arranged away from the first channel 402 and the second channel 403, and its height gradually increases away from the first channel 402 and the second channel 403. Specifically, there are two guide slopes 406, and the two guide slopes 406 are arranged opposite to each other, so that the two guide slopes 406 can be slidably connected with the two lifting slopes 301, so that when the driving member 10 is toggled, the lifting slope 301 can slide along the guide slope 406, so that the movable rod 30 moves up and down in the first channel 402 or the second channel 403, so as to separate and connect the first channel 402 or the second channel 403 with the first inner cavity 401.

[0071] like Figure 14As shown, further, a guiding block 407 is provided in cooperation with the guiding inclined surface 406 to guide the axial movement of the movable rod 30. Optionally, the length of the guiding block 407 is greater than the height of the guiding inclined surface 406, and the radian of the guiding block 407 is adapted to the size of the movable rod 30, so as to ensure the stability of the forward and backward movement of the movable rod 30 when entering the first channel 402 or the second channel 403. Optionally, the water channel assembly 40 is convexly provided with a convex block 408 on the opposite side of the through hole 404 and the sealing groove 405 to be snap-connected with the positioning member 50.

[0072] As Figure 1 , Figure 15 and Figure 16 shown, in this embodiment, the positioning member 50 is provided with a second inner cavity 501, a guiding hole 502, a first arc-shaped groove 503 and a positioning groove 506. Optionally, the positioning groove 506 can be snap-connected with the convex block 408, so as to ensure the accurate positioning of the positioning member 50 in the water channel assembly 40 and the stable connection between the two. Further, after the positioning member 50 is connected to the water channel assembly 40, the second inner cavity 501 communicates with the first inner cavity 401, so as to ensure the smooth water supply of the waterway. Exemplarily, two guiding holes 502 are provided, and the positions are correspondingly arranged relative to the first channel 402 and the second channel 403. The top of the movable rod 30 is slidably arranged in the first channel 402 or the second channel 403, and the bottom is slidably arranged in the guiding hole 502, so as to ensure the stable installation of the movable rod 30. Further, the side of the guiding hole 502 facing away from the positioning groove 506 communicates with the first arc-shaped groove 503, and the first arc-shaped groove 503 communicates with the outside, so as to ensure the smooth movement of the movable rod 30 in the positioning member 50 without jamming.

[0073] Further, the second sealing ring 305 is located in the guiding hole 502 to prevent the water in the first inner cavity 401 from leaking in the guiding hole 502. Exemplarily, the first sealing ring 304 and the second sealing ring 305 are both V-shaped sealing rings with an umbrella-shaped structure, and the closed side of the first sealing ring 304 faces the first channel 402 or the second channel 403, and the open side faces the first inner cavity 401. The closed side of the second sealing ring 305 faces the first arc-shaped groove 503, and the open side faces the first inner cavity 401, so as to ensure that the water in the first inner cavity 401 flows into the first channel 402 or the second channel 403 according to the movement of the movable rod 30, or is sealed in the first inner cavity 401.

[0074] Further, the positioning member 50 is provided with a fourth limiting groove 504, a limiting ring 507 and a fifth limiting groove 505 from top to bottom. Specifically, the fourth limiting groove 504 is arranged above the first arc groove 503, and the limiting ring 507 is located between the first arc groove 503 and the fifth limiting groove 505. Optionally, the fourth sealing ring 510 is arranged in the fourth limiting groove 504 to ensure stable sealing between the positioning member 50 and the water channel assembly 40. Further, the fifth sealing ring 520 is arranged in the fifth limiting groove 505 to ensure stable sealing between the positioning member 50 and the water inlet structure. Exemplarily, when the positioning member 50 is connected to the water inlet structure, the position of the water inlet structure can be limited by the limiting ring 507, and the limiting ring 507 and the first arc groove 503 are arranged at intervals to prevent the water inlet structure from blocking the first arc groove 503 and affecting the smooth movement of the movable rod 30.

[0075] The specific structure of the water outlet device in this embodiment will be described below.

[0076] As Figures 1 - 9 and Figures 17 - 20 shown, the water outlet device in this embodiment includes the above-mentioned multi-functional switching element, the housing 100, the adapter 60, the water outlet member 70 and the water inlet member 80. Specifically, one end of the adapter 60 is connected to the top end of the water channel assembly 40 of the multi-functional switching element, the other end of the adapter 60 is connected to the water outlet member 70, and the water inlet member 80 is connected to the bottom end of the positioning member 50. Further, the housing 100 is sleeved outside the multi-functional switching element, the adapter 60, the water outlet member 70 and the water inlet member 80, and both the water outlet member 70 and the water inlet member 80 are screwed to the housing 100, thereby ensuring the overall installation stability of the water outlet device. Exemplarily, an avoidance hole is provided on the housing 100, and the driving member 10 of the multi-functional switching element extends out of the avoidance hole to facilitate the user to directly operate the driving member 10. Optionally, the housing 100 in this embodiment is set as an L-shaped cavity structure, and both the water outlet member 70 and the adapter 60 are arranged in its shorter cavity, and the multi-functional switching element and the water inlet member 80 are both located in its longer cavity, so as to change the water outlet direction and facilitate the user to use.

[0077] Combined with Figure 1 、 Figures 17 - 19As shown, the adapter 60 includes a bracket 61 and a body 62. A fixing block 611 is provided on the bracket 61, and a third channel 601, a fourth channel 602, a third inner cavity 603, a first annular cavity 604, and a second arc-shaped groove 605 are provided on the body 62. Optionally, in this embodiment, one end of the bracket 61 protrudes with a fixing block 611, and a fixing groove is provided on the inner wall of the corresponding housing 100. The fixing block 611 can be inserted into the fixing groove to ensure the stable placement of the adapter 60 in the housing 100. Further, the other end of the bracket 61 is connected to the body 62, the body 62 is inserted into the water outlet member 70, and the water outlet member 70 is screwed to the inner wall of the housing 100 to ensure the stability of the entire device.

[0078] As Figure 18 shown, in this embodiment, the third channel 601 in the body 62 communicates with the third inner cavity 603, the fourth channel 602 communicates with the first annular cavity 604, and the first annular cavity 604 is located outside the third inner cavity 603 to achieve two kinds of passages. Combining Figure 19 shown, a second arc-shaped groove 605 is also provided in the first annular cavity 604, and both sides of the second arc-shaped groove 605 communicate with the fourth channel 602 and the first annular cavity 604 respectively, thereby expanding the communication space between the fourth channel 602 and the first annular cavity 604 and improving the water flow efficiency. Combining Figures 6 - 8 shown, in this embodiment, the third channel 601 communicates with the first channel 402, and the fourth channel 602 communicates with the second channel 403, thereby ensuring the communication of the two waterways.

[0079] As Figure 1 、 Figure 18 shown, in this embodiment, a stepped groove 606 is provided at the outer end of the third inner cavity 603 to limit the installation of the sixth sealing ring 610 to seal the third inner cavity 603. Correspondingly, a sixth limiting groove 607 is provided at the outer end of the first annular cavity 604 to limit the installation of the seventh sealing ring 620 to seal the first annular cavity 604. Further, the third channel 601 and the fourth channel 602 extend along a first direction, and the third inner cavity 603 and the first annular cavity 604 both extend along a second direction, and the first direction is perpendicular to the second direction, so as to be able to change the water outlet direction and effectively improve the space utilization rate inside the housing 100.

[0080] As Figure 2 and Figure 20As shown, specifically, the water outlet member 70 is provided with a central hole group 701, shower holes 702, a second annular cavity 703, a third annular cavity 704, and a weight reduction groove 705. Optionally, the central hole group 701 is located at the central position of the water outlet member 70, and a plurality of shower holes 702 are provided. The plurality of shower holes 702 are evenly arranged circumferentially around the central hole group 701, thereby achieving two water outlet effects to meet the user's usage requirements. Further, a second annular cavity 703 is provided between the central hole group 701 and the shower holes 702, and the third annular cavity 704 is provided outside the second annular cavity 703 and communicates with the shower holes 702.

[0081] Combined with Figure 5 As shown, specifically, the stepped groove 606 is inserted into the second annular cavity 703 and is limited to the stepped surface of the second annular cavity 703. The sixth sealing ring 610 is then abutted against the side wall of the second annular cavity 703 to achieve the limit installation of the adapter 60 in the water outlet member 70, and at the same time, the third inner cavity 603 communicates with the central hole group 701, that is, the first channel 402, the third channel 601, the third inner cavity 603, and the central hole group 701 form a complete first water path. Correspondingly, the third limiting groove 409 is inserted into the third annular cavity 704, and the seventh sealing ring 620 is abutted against the side wall of the third annular cavity 704. At the same time, the first annular cavity 604 communicates with the shower holes 702, that is, the second channel 403, the fourth channel 602, the first annular cavity 604, and the shower holes 702 form a complete second water path. The first water path and the second water path can be quickly switched through the multi-functional switching element, and both water paths can be controlled to be closed. Exemplarily, a weight reduction groove 705 is provided on the water outlet member 70, and the weight reduction groove 705 is arranged circumferentially around the central hole group 701 and does not communicate with the inside of the water outlet member 70 to avoid leakage, and the weight of the device is reduced thereby.

[0082] As Figure 5 As shown, in this embodiment, the water inlet member 80 is provided with a water inlet channel 801. Optionally, one end of the water inlet channel 801 is for water inlet, and the other end communicates with the second inner cavity 501 of the positioning member 50 in the multi-functional switching element to ensure the stable water supply of the two water paths. Further, the fifth limiting groove 505 of the positioning member 50 is located in the water inlet channel 801, and the fifth sealing ring 520 abuts against the inner wall of the water inlet channel 801. The bottom surface of the limiting ring 507 abuts against the upper end surface of the water inlet member 80, thereby ensuring the stable connection and sealing between the positioning member 50 and the water inlet member 80 and avoiding leakage. Specifically, the water inlet channel 801 can be communicated with either the first water path or the second water path through the multi-functional switching element.

[0083] Working process: Water supply is ensured through the water inlet channel 801. The driving member 10 is toggled to drive the rotating rod 20 to rotate, and the switching gear 23 drives the gear portion 311 to rotate. Under the cooperation of the lifting inclined surface 301 and the guiding inclined surface 406, one of the two movable rods 30 axially moves relative to the rotating rod 20 to open or block the first waterway or the second waterway. At the same time, the movable rod 30 can also be restored to the initial position to close both waterways. As Figure 7 shown, when the driving member 10 is toggled to one of the adjustment positions, the movable rod 30 corresponding to the first waterway can be driven to move away from the first channel 402 to open the first waterway, while the movable rod 30 corresponding to the second waterway keeps blocking the second waterway. Thus, water enters the second inner cavity 501 from the water inlet channel 801 and then enters the first inner cavity 401, and successively passes through the first channel 402, the third channel 601, and the third inner cavity 603, and is ejected from the central hole group 701. As Figure 8 shown, when the driving member 10 is toggled to the other adjustment position, the movable rod 30 corresponding to the second waterway can be driven to move away from the second channel 403 to open the second waterway, while the movable rod 30 corresponding to the first waterway keeps blocking the first waterway. Thus, water enters the second inner cavity 501 from the water inlet channel 801 and then enters the first inner cavity 401, and successively passes through the second channel 403, the fourth channel 602, and the first annular cavity 604, and is ejected from the shower holes 702. As Figure 9 shown, when the driving member 10 is toggled to the closed position to restore the initial position of the movable rod 30, both the first waterway and the second waterway are closed. Thus, water enters the second inner cavity 501 from the water inlet channel 801 and then enters the first inner cavity 401 for storage.

[0084] Exemplarily, in this embodiment, the area of the first sealing ring 304 is larger than the area of the second sealing ring 305. Thus, under the action of water pressure and when the driving member 10 is in the closed position, both the first waterway and the second waterway can be blocked. Further, when the driving member 10 is toggled from the closed position to the adjustment position, or from the adjustment position to the closed position, since V-shaped sealing rings with an umbrella-shaped structure are provided at both the upper and lower ends of the movable rod 30, under the action of hydraulic balance, the movable rod 30 can move upward or downward along the guiding inclined surface 406 without having to overcome a large water pressure, thereby ensuring the connection and closing of the first waterway or the second waterway and realizing the switching between two water outlet states.

[0085] Exemplarily, when the driving member 10 is toggled from the closed position to any adjustment position, only one movable rod 30 rotates and axially moves towards the positioning member 50 to open the corresponding water passage. When the driving member 10 is toggled back to the closed position again, the movable rod 30 rotates and axially moves away from the positioning member 50 to close the corresponding water passage. At this time, the movable rod 30 corresponding to the other water passage always remains in the initial state until the driving member 10 is toggled from the closed position to another adjustment position, and then the movable rod 30 corresponding to the other water passage will move accordingly. Thus, by toggling the driving member 10 in different directions, one-to-one control of the two movable rods 30 can be achieved.

For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
