[0002] As the performance of spray guns continues to expand, the switching methods for different water effects are mostly divided into pressing, pushing, and rotating. When using the pressing method to switch the water outlet, the force is usually large under high pressure, which is not easy to operate and has limited functions. It only has a single function and requires repeated operation, which reduces the customer experience; when using the pushing method to switch, the switching resistance is usually large, and the rotation angle of the valve core is too large, which requires the user to operate vigorously and cannot be achieved through simple operations such as finger turning; when using the rotating method to switch, the rotation angle and force need to be controlled, which can easily damage the device. At the same time, the spray gun is not equipped with a closing function during the switching process.

[0051] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0052] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, mechanical or electrical connections, direct or indirect connections through an intermediate medium, and internal communication between two elements or interaction between two elements. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0053] In the description of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0054] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0055] like Figures 1-20 As shown, this embodiment provides a multifunctional 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 rod 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 channels; the driving member 10 has at least an adjustment position and a closing position. When the driving member 10 is moved to any adjustment position, one of the plurality of water channels is opened and the others are closed. When the driving member 10 is moved to the closing position, the plurality of water channels are all closed.

[0056] On the other hand, the water outlet device includes a multifunctional switching element, an adapter 60, a water outlet part 70, a water inlet part 80 and a shell 100. One end of the adapter 60 is connected to the multifunctional switching element, and the other end is connected to the water outlet part 70. The water inlet part 80 is connected to the other end of the multifunctional switching element. The shell 100 is mounted on the outside of the multifunctional switching element, the adapter 60, the water outlet part 70 and the water inlet part 80, and the water outlet part 70 and the water inlet part 80 are both screwed to the shell 100. The driving part 10 of the multifunctional switching element extends out of the shell 100.

[0057] Specifically, the driver 10 in this embodiment facilitates user operation. By shifting the driver 10, the rotating rod 20 is synchronously rotated. The engagement of the rotating rod 20 with the movable rod 30 allows for switching between different water channels. Furthermore, the driver 10 is provided with an adjustment position and a closed position. When the driver 10 is shifted to any adjustment position, one of the multiple water channels is opened, while the others are closed, thereby enabling switching between different water channels. When the driver 10 is shifted to the closed position, all water channels are closed, thereby enhancing the closing function. Furthermore, adjustment via the driver 10 not only reduces the rotation angle, thus reducing the operating range, but also simplifies the structure, reduces the effort required, and reduces the cost of the product. Furthermore, the device is suitable for spray guns with different water discharge effects. Accordingly, the water outlet device equipped with a multifunctional switching element can achieve complete spraying of two water channels, enabling effortless switching between high and low pressures through simple operation, and can simultaneously close multiple water channels, thus conserving water resources.

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

[0059] Combine Figure 1 、 Figure 3-Figure 9 As shown, the multifunctional switching element in this embodiment includes a driving member 10, a rotating rod 20, an active rod 30, a water channel 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 multiple active rods 30, and multiple active rods 30 are engaged with the rotating rod 20. Therefore, when the rotating rod 20 rotates in different directions, it can drive the corresponding active rods 30 to rotate, thereby opening or blocking different water channels to achieve water channel switching. Furthermore, in this embodiment, the driving member 10 has at least an adjustment position and a closed position, and the adjustment position is set corresponding to the water channel. Therefore, when the driving member 10 is moved from the closed position to any adjustment position, one of the multiple water channels is opened and the other channels remain closed. When switching to other adjustment positions, the water channels are interchanged in on and off, thereby achieving water channel switching. Specifically, when the driving member 10 is moved to the closed position, all water channels are closed, thereby shutting off the water flow through the multifunctional switching element when the user is not in use.

[0060] For example, in this embodiment, two movable rods 30 are provided, corresponding to two water channels. The movable rods 30, water channels, and adjustment positions are arranged in a one-to-one correspondence, ensuring 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, with the closed position located between the two adjustment positions, so that the two water channels transition through the closed position when switching, improving the user experience.

[0061] Optionally, in this embodiment, both the rotating rod 20 and the movable rod 30 are rotatably disposed in the waterway assembly 40, and the rotating rod 20 can extend from the waterway assembly 40 to connect to the driving member 10. Furthermore, 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, thereby ensuring the stable placement of the movable rod 30. Driven by the rotating rod 20, the movable rod 30 can rotate in the waterway assembly 40 and the positioning member 50, and the movable rod 30 can also move up and down along its axis to realize the opening and closing of the two waterway channels.

[0062] Combine 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, the toggle portion 11 is provided with two operating inclined surfaces at an angle, thereby facilitating the user to toggle the driving member 10 via the operating inclined surfaces, thereby simplifying operation. 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. The driving member 10 and the rotating rod 20 are prevented from rotating relative to each other, thereby enabling the rotating rod 20 to rotate synchronously when the driving member 10 is toggled. Exemplarily, the connecting hole is provided with a non-circular shape and a first positioning plane. The portion where the rotating rod 20 connects to the driving member 10 is adapted to its shape, and the first positioning plane is used to limit and fix the two to ensure stable insertion and prevent them from moving axially but not 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 this embodiment, the rotating rod 20 includes a first rod 21, a first base 22, and a switching gear 23. The first rod 21 is provided with a second positioning plane 211 and a stepped surface 212, and a sealing member 201 is sleeved on the first rod 21. Optionally, the first base 22 is configured as a columnar structure, and the first rod 21 is disposed above the first base 22 along the axis of the first base 22. The switching gear 23 is disposed on the side of the first base 22. The first rod 21, the first base 22, and the switching gear 23 form an L-shaped structure. Optionally, the driving member 10 is sleeved on the first rod 21, and the shape of the connecting hole is adapted to the shape of the first rod 21. The first positioning plane and the second positioning plane 211 are slidably arranged to ensure a stable connection between the two. Under 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 21 on the first rod 21, and cannot rotate relative to the first rod 21.

[0064] Furthermore, the second positioning plane 211 extends along the axis of the first rod 21, and the step surface 212 extends radially along the first rod 21. Specifically, the second positioning plane 211 and the step surface 212 are perpendicular to each other and form an L-shaped step. Specifically, the driver 10 is positioned above the step surface 212 to limit the range of movement of the driver 10 on the first rod 21. Exemplarily, the seal 201 is sleeved onto the first rod 21 and positioned between the driver 10 and the first base 22. In this embodiment, the seal 201 is configured as an umbrella-shaped sealing ring.

[0065] Specifically, the switching gear 23 is provided on the side of the first base 22, and the switching gear 23 is an incomplete gear, thereby avoiding taking up too much space, and being able to drive each movable rod 30 one-to-one by shifting in opposite directions as needed. In other embodiments, the meshing length of the switching gear 23 can also be adjusted to achieve simultaneous driving of the two movable rods 30, and the two move in opposite directions at the same time, thereby changing the rotation direction of the driving member 10, and then swapping the movement directions of the two, thereby achieving switching of the two waterways. The specific adjustment method can be set as needed and will not be described here. For example, in this embodiment, the switching gear 23 is engaged with the movable rod 30, and when the driving member 10 is shifted and the rotating rod 20 is driven 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, making it convenient for the user to adjust.

[0066] like Figure 4-Figure 9 、 Figure 11As shown, in this embodiment, the movable rod 30 includes a second base 31 and a second rod 32, and the second base 31 is provided with a gear portion 311 and a lifting portion 312, and the lifting portion 312 is provided with a lifting inclined surface 301. Specifically, the second base 31 is configured as a columnar shape. In this embodiment, the second rod 32 is disposed above the second base 31 along the axis of the second base 31. Furthermore, the gear portion 311 is an incomplete gear, and the gear portions 311 on the two movable rods 30 are respectively located on either side of the switching gear 23 and can mesh with the switching gear 23. As a result, the two gear portions 311 can be rotated separately or simultaneously under the drive of the switching gear 23, thereby achieving the rotation of the two movable rods 30 separately or simultaneously. In this embodiment, the two gear portions 311 are respectively engaged with the switching gear 23 to achieve independent rotation, completing the opening and closing of the corresponding waterway. 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, thereby ensuring that the gear portion 311 is engaged with the switching gear 23 and does not fall off when the movable rod 30 moves up and down along its axial direction. Exemplarily, a lifting portion 312 is provided on the back side of the gear portion 311, and the lifting portion 312 is protruding from the side of the second base 31, and a spirally rising lifting slope 301 is provided on its top surface. Optionally, the lifting slope 301 is provided toward the second rod body 32, and its height gradually increases as it approaches the second rod body 32. Specifically, the two movable rods 30 are arranged relative to each other, that is, the two lifting slopes 301 are arranged facing each other, thereby enabling the two movable rods 30 to move upward and downward respectively by rotating the rotating rod 20 in different directions, or in other embodiments, the two movable rods 30 are moved in opposite directions at the same time.

[0067] like Figure 1 and Figure 11 As shown, the movable rod 30 is further provided with a first limiting groove 302 and a second limiting groove 303 at the upper and lower ends of the second base 31, respectively. A first sealing ring 304 is disposed in the first limiting groove 302, and a second sealing ring 305 is disposed in the second limiting groove 303, thereby ensuring a seal between the upper and lower ends of the movable rod 30. For example, the first sealing ring 304 and the second sealing ring 305 are both made of a corrosion-resistant rubber material, thereby ensuring a stable seal while preventing damage to the inner wall of the channel when the movable rod 30 moves up and down.

[0068] like Figure 1 、 Figure 3-Figure 9 and Figure 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 the 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 inserted into the sealing groove 405 and the through hole 404 and extends 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 movably arranged in the first channel 402 and the second channel 403, respectively, 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. Therefore, after the sealing member 201 is sleeved on the first rod 21, it can be confined in the sealing groove 405. Specifically, in this embodiment, the sealing member 201 is an umbrella-shaped sealing ring, and its closed side is against 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 to the through hole 404, thereby avoiding 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] Combine Figure 13 and Figure 14 As shown, the inner wall of the water channel assembly 40 is further provided with a guide slope 406, a guide block 407 and a protrusion 408. Optionally, the guide slope 406 is spirally arranged downward 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 to the two lifting slopes 301. When the driving member 10 is toggled, the lifting slope 301 can slide along the guide slopes 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, a guide block 407 is further provided in conjunction with the guide ramp 406 to guide the axial movement of the movable rod 30. Optionally, the length of the guide block 407 is greater than the height of the guide ramp 406, and the curvature of the guide block 407 is adapted to the size of the movable rod 30, thereby ensuring the stability of the movable rod 30's forward and backward movement when entering the first channel 402 or the second channel 403. Optionally, the waterway assembly 40 has an inwardly projecting bump 408 on opposite sides of the through hole 404 and the sealing groove 405 to engage with the positioning member 50.

[0072] like Figure 1 、 Figure 15 and Figure 16 As shown, in this embodiment, the positioning member 50 is provided with a second inner cavity 501, a guide hole 502, a first arc-shaped groove 503 and a positioning groove 506. Optionally, the positioning groove 506 can be engaged with the protrusion 408 to ensure the accurate positioning of the positioning member 50 in the water channel assembly 40 and the stable connection between the two. Furthermore, after the positioning member 50 is connected to the water channel assembly 40, the second inner cavity 501 is connected to the first inner cavity 401 to ensure smooth water supply in the waterway. Exemplarily, there are two guide holes 502, and the positions are set corresponding to the first channel 402 and the second channel 403. The top of the movable rod 30 is slidably set in the first channel 402 or the second channel 403, and the bottom is slidably set in the guide hole 502 to ensure the stable installation of the movable rod 30. Furthermore, the side of the guide hole 502 away from the positioning groove 506 is connected to the first arc groove 503, and the first arc groove 503 is connected to the outside, thereby ensuring smooth movement of the movable rod 30 in the positioning member 50 without jamming.

[0073] Furthermore, the second sealing ring 305 is located in the guide hole 502 to prevent water in the first inner cavity 401 from leaking into the guide hole 502. For example, the first sealing ring 304 and the second sealing ring 305 are both configured as V-shaped sealing rings with an umbrella-shaped structure, and the closed side of the first sealing ring 304 is arranged toward the first channel 402 or the second channel 403, and the open side is arranged toward the first inner cavity 401. The closed side of the second sealing ring 305 is arranged toward the first arc-shaped groove 503, and the open side is arranged toward the first inner cavity 401. In this way, it is possible 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] Furthermore, 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 provided above the first arc-shaped groove 503, and the limiting ring 507 is located between the first arc-shaped groove 503 and the fifth limiting groove 505. Optionally, a fourth sealing ring 510 is provided in the fourth limiting groove 504 to ensure a stable seal between the positioning member 50 and the waterway assembly 40. Further, a fifth sealing ring 520 is provided in the fifth limiting groove 505 to ensure a stable seal 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 is spaced apart from the first arc-shaped groove 503 to avoid the water inlet structure blocking the first arc-shaped groove 503 and affecting the smooth movement of the movable rod 30.

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

[0076] like Figures 1-9 and Figures 17-20 As shown, the water outlet device in this embodiment includes the above-mentioned multifunctional switching element, a housing 100, an adapter 60, a water outlet part 70 and a water inlet part 80. Specifically, one end of the adapter 60 is connected to the top of the water channel assembly 40 of the multifunctional switching element, the other end of the adapter 60 is connected to the water outlet part 70, and the water inlet part 80 is connected to the bottom end of the positioning member 50. Furthermore, the housing 100 is sleeved on the outside of the multifunctional switching element, the adapter 60, the water outlet part 70 and the water inlet part 80, and the water outlet part 70 and the water inlet part 80 are both screwed to the housing 100, thereby ensuring the stability of the overall installation of the water outlet device. For example, an avoidance hole is provided on the housing 100, and the driving part 10 of the multifunctional switching element extends out of the avoidance hole so that the user can directly operate the driving part 10. Optionally, in this embodiment, the shell 100 is configured as an L-shaped cavity structure, and the water outlet part 70 and the adapter part 60 are both arranged in its shorter cavity, and the multifunctional switching element and the water inlet part 80 are both located in its longer cavity, thereby changing the water outlet direction for user convenience.

[0077] Combine Figure 1 、 Figure 17-Figure 19As shown, the adapter 60 includes a bracket 61 and a body 62. The bracket 61 is provided with a fixing block 611, and the body 62 is provided with a third channel 601, a fourth channel 602, a third inner cavity 603, a first annular cavity 604, and a second arcuate groove 605. Optionally, in this embodiment, the bracket 61 is provided with a fixing block 611 protruding from one end, and a fixing groove is provided on the inner wall of the 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. Furthermore, the other end of the bracket 61 is connected to the body 62, and the body 62 is inserted into the water outlet 70. The water outlet 70 is screwed to the inner wall of the housing 100 to ensure the stability of the entire device.

[0078] like Figure 18 As shown, in this embodiment, the third channel 601 in the body 62 is connected to the third inner cavity 603, and the fourth channel 602 is connected to the first annular cavity 604, and the first annular cavity 604 is located outside the third inner cavity 603, thereby realizing two passages. Figure 19 As shown, a second arc groove 605 is further provided in the first annular cavity 604, and both sides of the second arc groove 605 are respectively connected to the fourth channel 602 and the first annular cavity 604, thereby expanding the connecting space between the fourth channel 602 and the first annular cavity 604 and improving the water flow efficiency. Figure 6-Figure 8 As shown, in this embodiment, the third channel 601 is connected to the first channel 402, and the fourth channel 602 is connected to the second channel 403, thereby ensuring the connection between the two waterways.

[0079] like Figure 1 、 Figure 18 As shown, in this embodiment, a stepped groove 606 is provided at the outer end of the third inner cavity 603 to facilitate the positional installation of a 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 facilitate the positional installation of a seventh sealing ring 620 to seal the first annular cavity 604. Furthermore, the third channel 601 and the fourth channel 602 both extend along a first direction, and the third inner cavity 603 and the first annular cavity 604 both extend along a second direction, with the first direction and the second direction being perpendicular to each other. This allows the water outlet direction to be changed and effectively improves the space utilization rate inside the housing 100.

[0080] like Figure 2 and Figure 20Specifically, the water outlet member 70 is provided with a central hole group 701, a shower hole 702, a second annular cavity 703, a third annular cavity 704, and a weight-reducing groove 705. Optionally, the central hole group 701 is located at the center of the water outlet member 70, and multiple shower holes 702 are provided, evenly arranged along the circumference of the central hole group 701, thereby achieving two water discharge effects to meet user needs. Furthermore, a second annular cavity 703 is provided between the central hole group 701 and the shower hole 702, and a third annular cavity 704 is provided outside the second annular cavity 703 and connected to the shower hole 702.

[0081] Combine Figure 5 Specifically, the stepped groove 606 is inserted into the second annular cavity 703 and is positioned on the stepped surface of the second annular cavity 703. The sixth sealing ring 610 abuts against the sidewall of the second annular cavity 703, thereby limiting the installation of the adapter 60 in the water outlet 70. This allows the third inner cavity 603 to communicate with the central hole group 701, thereby forming a complete first waterway. Accordingly, the third limiting groove 409 is inserted into the third annular cavity 704, while the seventh sealing ring 620 abuts against the sidewall of the third annular cavity 704, thereby connecting the first annular cavity 604 to the shower hole 702. Therefore, the second channel 403, the fourth channel 602, the first annular cavity 604, and the shower hole 702 form a complete second waterway. The multifunctional switching element can quickly switch between the first and second waterways, as well as control both waterways to be closed. Exemplarily, a weight-reducing groove 705 is provided on the water outlet 70 , and the weight-reducing groove 705 is arranged along the circumference of the central hole group 701 , and is not connected to the inside of the water outlet 70 to avoid leakage, thereby reducing the weight of the equipment.

[0082] like 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 used for water inlet, and the other end is connected to the second inner cavity 501 of the positioning member 50 in the multifunctional switching element to ensure stable water supply for the two waterways. Furthermore, 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, and the bottom surface of the limiting ring 507 abuts against the upper end surface of the water inlet member 80, thereby ensuring a stable connection and seal between the positioning member 50 and the water inlet member 80 to avoid leakage. Specifically, the multifunctional switching element can realize the connection between the water inlet channel 801 and either the first waterway or the second waterway.

[0083] Working process: water supply is ensured through the water inlet channel 801, the rotating rod 20 is driven to rotate by toggling the driving member 10, and the switching gear 23 drives the gear part 311 to rotate, and under the cooperation of the lifting slope 301 and the guide slope 406, one of the two movable rods 30 is moved axially relative to the rotating rod 20 to open or block the first waterway or the second waterway, and at the same time, the movable rod 30 can be restored to the initial position to close both waterways. Figure 7 As shown, when the driving member 10 is moved to one of the adjustment positions, the movable rod 30 corresponding to the first water channel is driven to move away from the first channel 402, thereby opening the first water channel. At the same time, the movable rod 30 corresponding to the second water channel remains blocked, so that water enters the second inner cavity 501 from the water inlet channel 801 and then enters the first inner cavity 401, and then passes through the first channel 402, the third channel 601, and the third inner cavity 603 in sequence, and is ejected from the central hole group 701. Figure 8 As shown, when the driving member 10 is moved to another adjustment position, the movable rod 30 corresponding to the second water channel is driven to move away from the second channel 403, thereby opening the second water channel. At the same time, the movable rod 30 corresponding to the first water channel remains blocked to block the first water channel. Thus, water enters the second inner cavity 501 through the water inlet channel 801 and then enters the first inner cavity 401. It then passes through the second channel 403, the fourth channel 602, and the first annular cavity 604 in sequence and is ejected from the shower hole 702. Figure 9 As shown, when the driving member 10 is moved to the closed position to restore the initial position of the movable rod 30, the first water channel and the second water channel are both closed, so that water enters the second inner cavity 501 from the water inlet channel 801 and then enters the first inner cavity 401 for storage.

[0084] For example, 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, when the driver 10 is in the closed position, both the first and second water channels can be blocked. Furthermore, when the driver 10 is moved from the closed position to the adjustment position, or from the adjustment position to the closed position, the movable rod 30 is provided with umbrella-shaped V-shaped sealing rings at the upper and lower ends. Under the action of hydraulic balance, the movable rod 30 can be moved upward or downward along the guide slope 406 without overcoming significant water pressure, thereby ensuring the connection and closure of the first or second water channel, and achieving the switching between the two water outlet states.

[0085] For example, when the driving member 10 is moved from the closed position to any adjustment position, only one movable rod 30 rotates and moves axially toward the positioning member 50 to open the corresponding waterway. When the driving member 10 is moved back to the closed position again, the movable rod 30 rotates and moves axially away from the positioning member 50 to close the corresponding waterway. At this time, the movable rod 30 corresponding to the other waterway is always in the initial state until the driving member 10 is moved from the closed position to another adjustment position. The movable rod 30 corresponding to the other waterway will move accordingly. Therefore, the one-to-one corresponding regulation of the two movable rods 30 can be achieved by moving the driving member 10 in different directions.

[0086] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
