[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "vertical", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Referring to the accompanying drawings, a water channel switching structure includes a body 1, a water channel assembly 2, a transmission mechanism 3, a water distribution mechanism 4, and a water outlet panel 5. The water channel assembly 2, transmission mechanism 3, water distribution mechanism 4, and water outlet panel 5 are installed on the body 1. The water inlet of the water channel assembly 2 is connected to the water inlet pipe 20. The water channel assembly 2 is provided with a pause water chamber 21 and a switching chamber 22, which are interconnected by an intermediate channel 26. The pause water chamber 21 is provided with a water-stopping shaft 23, which includes a baffle 231. The baffle 231 can connect or block the intermediate channel 26 to control the connection or blockage between the pause water chamber 21 and the switching chamber 22. The water channel assembly 2 also forms a first slide rail 24 and a second slide rail 25, which are arranged in different planes. Thus, when water flows in from the inlet pipe 20 and then into the pause water chamber 21 of the water channel assembly; when the pause water chamber 21 is closed, the baffle 231 of the water-stop shaft closes the outlet of the pause water chamber (as shown in the figure above), that is, the intermediate channel 26 is blocked by the baffle 231, and at this time it is in pause water mode; when the baffle 231 of the water-stop shaft does not close the outlet of the pause water chamber (the outlet of the pause water chamber is open), that is, the intermediate channel 26 is in a connected state, water flows into the switching chamber 22, and then connects with different water outlets of the water divider through the inlet of the turntable, realizing water output from different functional outlets on the panel assembly. The pause water function of the present invention is controlled by a separate water circuit, which can effectively reduce the switching force of the pause water function.

[0035] The transmission mechanism 3 includes a push button 30, a transmission rod 31, a transmission rack 32, a pause gear 33, and a transmission gear 34. The push button 30 is connected to the transmission rod 31, and the transmission rod 31 can be moved by pushing / pulling the push button 30. The transmission rod 31 is installed on the first slide rail 24 of the water channel assembly, and a transmission shaft 311 is provided at one end of the transmission rod 31. The transmission rack 32 is arranged on the second slide rail 25 of the water channel assembly, and the transmission rack 32 is located between the pause water cavity 21 and the switching cavity 22. The transmission rack 32 has a first gear 321 and a second gear 322 on both sides, which are used to mesh with the pause gear 33 and the transmission gear 34, respectively. Furthermore, the transmission rack 32 also has a transmission groove 323, which can cooperate with the transmission shaft 311. The aforementioned pause gear 33 is connected to the water-stop shaft 23, and the pause gear 33 and the water-stop shaft 23 are coaxially connected and arranged, allowing the water-stop shaft 23 to rotate under the drive of the pause gear 33. The aforementioned transmission gear 34 is coaxially connected to the turntable 40, which is installed in the switching cavity 22. The turntable 35 can rotate under the drive of the transmission gear 34. Furthermore, the aforementioned transmission gear 34 is also provided with several stop holes, which can cooperate with the ball mechanism to achieve gear switching. The ball mechanism includes a ball 34a and an elastic element 34b, and the ball 34a can cooperate with the stop holes to achieve gear switching. The turntable 40 and the water-stop shaft 23 drive the transmission rod 31 to move back and forth along the first slide rail 24 on the water channel assembly by pushing / pulling the push button 30. The transmission shaft 311 on the transmission rod 31 is embedded in the transmission groove 323 of the transmission rack, which drives the transmission rack 32 to move back and forth along the second slide rail 25. The gears 321 and 322 on both sides of the transmission rack 32 are respectively engaged with the pause gear 33 and the transmission gear 34 to convert the linear motion of the transmission rack 32 back and forth into circular motion, so as to drive the water-stop shaft 23 and the turntable 40 to rotate around their respective rotation centers, thereby realizing the function switching.

[0036] The aforementioned water distribution mechanism 4 includes a turntable 40, a water distribution plate 41, an inclined water body 42, and an impeller 43. The turntable 40 is coaxially arranged with the aforementioned transmission gear 34. The turntable 40 includes a rotating shaft 401, a first disc body 402, and a second disc body 403. The rotating shaft 401 has a groove, in which a spring 40a and a wear-resistant sleeve 40b are sequentially arranged. A first sealing gasket b1 is provided between the first disc body 402 and the water channel assembly 2, and a second sealing gasket b2 is also provided between the second disc body 403 and the water distribution plate 41. At the same time, the second disc body 403 also has a first water inlet hole 404 and a second water inlet hole 405 arranged opposite to each other. The first and second water inlets 404 and 405 can be connected to the water distribution ports of the water distribution plate with the same or different functions, respectively. The turntable and the water distribution plate are sealed and connected by the sealing gasket. The water inlet hole of the turntable can selectively connect to the water distribution holes or groups of water distribution holes arranged opposite to each other on the water distribution plate, thereby realizing single or mixed function water output. The aforementioned turntable 40 is a pressure balancing structure. Under the condition that the diameter of the second disc 403 remains unchanged, the pressure on the turntable 40 is reduced by adjusting the diameter of the first disc 402, for example, as shown in the attached figure, where the diameters of the two discs are different, with the diameter of the second disc 403 being larger than that of the first disc 402. This results in less pressure during function switching under high pressure, a lighter feel, and an improved user experience. In addition, the wear-resistant sleeve 40b and spring 40a can provide sufficient pressure for the sealing of the turntable 40 under low pressure, ensuring that the turntable and the water separator are well sealed through the sealing gasket. The front of the aforementioned water divider 41 has a first water dividing hole 41a and a second water dividing hole 41b, which are respectively connected to the first water inlet 404 and the second water inlet 405. In one embodiment, the first and second water dividing holes 41a and 41b can be connected to water outlets with the same function, such as achieving water spray patterns like shower head or blade water. If the baffle 231 of the water stop shaft blocks the middle channel 26, a water pause mode can be achieved; if the baffle 231 of the water stop shaft does not block the middle channel 26, a functional water spray pattern can be achieved. In another embodiment, the back of the water divider 41 may include a water dividing functional area one 411 and a water dividing functional area two 412. The first water dividing hole 41a and the second water dividing hole 41b are respectively connected to the water dividing functional area one 411 and the water dividing functional area two 412, and the water dividing functional area one 411 and the water dividing functional area two 412 are respectively connected to different water outlets, thereby achieving different water spray patterns. In a preferred embodiment, the first or second water distribution hole can be further divided into a plurality of adjacent water outlets by means of ribs c. Such an arrangement can improve the water spray ratio for different functions and enhance the user experience.

[0037] With attachment Figure 13 and attached Figure 14For example, the back of the water distribution plate 41 includes four water distribution functional areas, namely water distribution functional area one 411, water distribution functional area two 412, water distribution functional area three 413, and water distribution functional area four 414, which correspond to, for example, massage water channels, inner ring water channels, blade water channels, and shower water channels. The water distribution functional areas one 411, two 412, three 413, and four 414 are respectively connected to the water distribution holes on the front of the corresponding water distribution plate. For example, the first water distribution hole 41a and the second water distribution hole 41b of the above-mentioned water distribution plate are connected to the first water distribution functional area 411 and the second water distribution functional area 412, respectively. When the water flows from the first and second water inlets 404 and 405 of the rotating water plate into the first water distribution hole 41a and the second water distribution hole 41b, respectively, and flows into the first water distribution functional area 411 and the second water distribution functional area 412, the mixed water output of different functional water paths, such as massage water + inner ring water path, is realized.

[0038] The aforementioned water outlet panel 5 has water outlets corresponding to different water outlet functions, as shown in the attached diagram. Figure 15 For example, the water outlet panel 5 has a first water outlet 51, a second water outlet 52, a third water outlet 53, and a fourth water outlet 54. The first, second, third, and fourth water outlets 51, 52, 53, and 54 are respectively connected to the above-mentioned water distribution functional areas 1, 2, 3, and 414 to form massage water outlet, inner ring water outlet, blade water outlet, and shower water outlet. The above-mentioned inclined water body 42 and impeller 43 are installed on the water outlet panel 5. The water flow enters from the inclined water body 42 and impacts the impeller 43, thereby driving the impeller 43 to rotate.

[0039] See attached document Figure 16 and attached Figure 17The above structure enables mixed-function water output. When the first water inlet 404 and the second water inlet 405 of the turntable 40 are connected to the same or different water distribution functional areas, respectively, they realize their corresponding single or mixed-function water output. When the ball 34a is located in the first gear hole 341 of the transmission gear, the baffle 231 of the water-stop shaft closes the outlet of the pause water chamber (when the ball 34a is located in other gear holes, the baffle 231 of the water-stop shaft does not close the outlet of the pause water chamber). At this time, it is pause water mode S1. Since the pause water function (dripping) is set on the water distribution port of the water distribution plate, such as its corresponding shower water distribution hole, in the pause water mode, the water inlet of the turntable is connected to the shower water circuit. At this time, the water inlet of the turntable is connected to the water distribution hole of the water distribution plate 41. When the ball 34a is located in the second gear position hole 342 of the transmission gear, the first water inlet hole 404 and the second water inlet hole 405 of the turntable are respectively connected to the water distribution holes of the water distribution plate 41, that is, all the water inlets of the turntable are connected to the third water distribution functional area 413, that is, the blade water passage S2 is opened, and the water outlet panel realizes the blade water output; when the ball 34a is located in the third gear position hole 343 of the transmission gear, the first water inlet hole 404 and the second water inlet hole 405 of the turntable are respectively connected to the water distribution holes of the water distribution plate 41, that is, all the water inlets of the turntable are connected to the first water distribution functional area 411, that is, the massage water passage S3 is opened, and the water outlet panel realizes the massage water output; when the ball 34a is located in the fourth gear position hole 344 of the transmission gear, the first water inlet hole 404 and the second water inlet hole 405 of the turntable are respectively connected to the second water distribution functional area 411 and the second water distribution functional area 412 of the water distribution plate 41. When the inner ring water + massage water path S4 is opened, the water outlet panel can achieve mixed water output of inner ring water and massage water; when the ball bearing 34a is located in the fifth gear hole 345 of the transmission gear, the first water inlet hole 404 and the second water inlet hole 405 of the turntable are both connected to the second water distribution functional area 412, the inner ring water path S5 is opened, and the water outlet panel can achieve inner ring water output; when the ball bearing 34a is located in the sixth gear hole 346 of the transmission gear, the first water inlet hole 404 and the second water inlet hole 405 of the turntable are connected to the second water distribution functional area 412 and the fourth water distribution functional area 414 respectively, the inner ring water + shower water path S6 is opened, and the water outlet panel can achieve mixed water output of inner ring water and shower water; when the ball bearing 34a is located in the seventh gear hole 347 of the transmission gear, the first water inlet hole 404 and the second water inlet hole 405 of the turntable are both connected to the fourth water distribution functional area 414, the shower water path S7 is opened, and the water outlet panel can achieve shower water output. This structural layout design enables the combination of single or mixed water output functions, enriching the variety of water output functions. At the same time, it can better distribute the various function levels evenly, ensuring that the switching stroke of each function is evenly distributed, resulting in a consistent feel when switching functions and improving the customer experience.
