[0020] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The main channel is located downstream of the Venturi inlet, therefore the water flowing into the Venturi inlet enters the main channel. Because two first bends are located on either side of the main channel, due to the wall effect, most of the water flowing into the main channel adheres to one of the first bends, while a circulating vortex forms at the other bend. (Here, it is assumed that the water initially adheres to the wall...) Figure 8 The flow occurs in the first bend on the right side of the channel, while a circulating vortex forms in the area of ​​the main channel near the first bend on the left side. The following left and right views refer to the adjacent... Figure 8 As the circulating vortex gradually expands to its maximum size, most of the water in the main channel flows closer to the first bend on the right and exits the outlet at the maximum bend angle to the left. During this process, a small portion of the water in the main channel enters the tributaries through the inlet sections, forming branch flows, and then flows from the outlet sections of the tributaries towards the main channel, impacting the water in the main channel. Because most of the water in the main channel is close to the first bend on the right, more water enters the left tributary than the right tributary, and the water from the left tributary dominates the impact on the main channel.

[0022] As the water flows, the circulating vortex gradually moves to the left, reducing the amount of water entering the left tributary and causing the vortex to shrink. Meanwhile, another circulating vortex forms between the main channel and the first bend on the right, resulting in two circulating vortices within the main channel. Consequently, the amount of water entering the right tributary gradually increases, leading to a gradual increase in the flow rate of water impacting the main channel from the right tributary. This causes the flow rates from the left and right tributaries to impact the main channel to become increasingly similar until they roughly cancel each other out. At this point, the water in the main channel flows out of the outlet in a roughly straight stream.

[0023] Although the water flows from the left and right tributaries into the main channel largely cancel each other out, the two circulating vortices still maintain their increasing or decreasing trends. At this point, the left circulating vortex continues to decrease, while the right circulating vortex continues to increase. As the water flows, the amount of water entering the right tributary continuously increases, leading to an increase in the amount of water impacting the main channel from the right tributary, until it exceeds the impact of the left tributary on the main channel. At this point, most of the water in the main channel is squeezed to the left by the right circulating vortex until it adheres to the first bend on the left due to the wall effect. The left circulating vortex disappears, and the right circulating vortex expands to its maximum size. The water in the main channel flows to the right at the maximum bend angle out of the outlet. As the water flows, the water inside the outlet gradually moves away from the first bend on the left in the same way, until it adheres to the first bend on the right. By repeating the above process, the water flowing out of the outlet is a periodically alternating pulse of water.

[0024] The inner wall of the outlet is set on the extension path of the first curved section to guide the main water flow along the first curved section to flow out of the outlet, so that the water flowing out of the outlet will not be dispersed by the inner wall of the outlet.

[0025] The Venturi inlet accelerates the water flow into the main channel, enabling faster wall adhesion and facilitating the rapid formation of circulating vortices, which in turn helps to achieve periodic alternating pulsed water flow.

[0026] 2. Connect the corresponding inlet and outlet sections through each connecting section. The inlet section is designed with a recess to prevent the water flow from flowing back due to impact with the inner wall of the tributary after entering the inlet section. The recess also guides the water flow to the connecting section, making the water flow smoother.

[0027] 3. A second bend is provided, and the second bend forms a side wall of the corresponding inlet section. The spacing of the second bend gradually increases along the direction away from the Venturi inlet, and both bends protrude toward the outlet to guide part of the main flow into the corresponding inlet section, so that the water flow is smoother.

[0028] 4. The water passage area of ​​the outlet gradually decreases in the direction away from the Venturi inlet, making the inner wall of the outlet inclined, which better guides the main water flow along the first bend to flow out of the outlet.

[0029] 5. The distance from the junction of the first and second curved sections to the central plane of the outlet is less than the maximum distance from the inner wall of the outlet to the central plane of the outlet. This allows the inner wall of the outlet to catch the water flowing from the main channel along the first curved section to the outlet, which helps to form a circulating water vortex and is more conducive to achieving periodic alternating pulse water.

[0030] 6. Due to the inclined arrangement of the first surface, the water depth of the Venturi inlet, main stream, outlet, and two branch channels gradually increases along the direction from the Venturi inlet to the outlet. This arrangement ensures that when multiple outlet components are installed together, the water flowing from each outlet is not only multiple pulsed water streams, but also interlaced, resulting in a larger water outlet range.

[0031] 7. The first section of each outlet section is an arc section, which can guide the water flow of the corresponding connecting section into the main channel from the second section, which is more conducive to realizing the periodic alternating pulse water.

[0032] 8. In this solution, by changing the water flow area of ​​the inlet section, the flow rate entering the branch channel can be adjusted, thereby regulating the oscillation frequency of the pulsed water. First flow-limiting blocks are installed between the corresponding second bend and the recess. When water flows from the second bend and the recess into the corresponding inlet section, the water flow area decreases due to the presence of the first flow-limiting blocks, controlling the flow rate entering the branch channel to adjust the oscillation frequency of the pulsed water. This solution, by setting the first flow-limiting blocks, allows for easier mold modification when the oscillation frequency needs adjustment in actual use, as the size of the first flow-limiting blocks in the mold can be modified.

[0033] 9. The second flow-limiting block can adjust the flow rate of the branch channel and regulate the oscillation frequency of the pulsed water. This solution, by setting a second flow-limiting block, allows for easier mold modification when the oscillation frequency needs adjustment in actual use, as the size of the second flow-limiting block in the mold can be modified.

[0034] 10. The sidewalls of the first flow limiting block and the second flow limiting block are both smooth curved surfaces, which can better guide the water flow into the corresponding inlet section and the corresponding outlet section, and avoid water backflow caused by the first limiting block and the second limiting block.

[0035] 11. The ratio of the water flow area of ​​the outlet to the water flow area of ​​the venturi inlet is 1.5-2, so that the pressure of the water flow entering the tributary impacting the main channel is within a reasonable range, neither too large nor too small.

[0036] 12. The ratio of the water flow area of ​​the tributary to the water flow area of ​​the venturi inlet is 0.4-0.6, so that the pressure of the water flow entering the tributary impacting the main channel is within a reasonable range, neither too large nor too small.

[0037] 13. The water outlet device is equipped with the aforementioned water outlet element, and therefore has all the beneficial effects of the aforementioned water outlet element. When the accommodating cavity accommodates multiple water outlet elements, the water flowing out of the water outlet channel from each outlet is a multi-pulse water that interweaves with each other, resulting in a larger water outlet range.

[0038] 14. Each accommodating chamber contains two water outlets, and the two water outlets are symmetrically arranged relative to the central axis of the accommodating chamber, so that the pulse water flowing out of the water outlet is inclined towards the other water outlet, and the two pulse water streams are staggered, resulting in a larger water outlet range.

[0056] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0057] like Figure 1 and Figure 2 As shown, the water outlet device includes a water outlet device body 1 and at least one water outlet component 3. In this embodiment, the first direction, the second direction, and the third direction are all... Figures 5 to 7 direction shown.

[0058] like Figures 1 to 4 As shown, the water outlet device body 1 is provided with an inlet channel 11, an outlet channel 123, and a receiving cavity 122 for accommodating at least one water outlet component 3. Specifically, the water outlet device body 1 is provided with an outlet main body 12 and a top cover 13. The outlet main body 12 extends along a third direction and is provided with a first cavity 121 with an opening at the top, several receiving cavities 122 arranged along the third direction, and an outlet channel 123. One end of each receiving cavity 122 opens into the bottom wall of the first cavity 121, and the other end communicates with the corresponding outlet channel 123. The top cover 13 is placed on the outlet main body 12 and covers the opening at the top of the first cavity 121; the top cover 13 and the cavity wall of the first cavity 121 together enclose to form an inlet channel 11 communicating with each receiving cavity 122.

[0059] In one exemplary embodiment, the number of receiving cavities 122 is N, and the number of water outlets 3 is 2N. Each receiving cavity 122 accommodates two water outlets 3, and the two water outlets 3 are symmetrically arranged with respect to the central axis A2 of the receiving cavity 122. The central axis A2 of the receiving cavity 122 is parallel to a first direction. Further, in this embodiment, the two water outlets 3 placed in each receiving cavity 122 are formed as a single unit, forming a group of water outlets 3.

[0060] like Figure 2 and Figure 5 As shown, the water outlet assembly 2 is a block that extends along the first direction and is adapted to the cavity wall of each of the accommodating cavities 122.

[0061] like Figures 5 to 7 As shown, the water outlet component 3 includes a main body 31 and a water outlet structure disposed on the main body 31. The water outlet structure is provided with a first surface 311, a Venturi inlet 34, a main stream, a water outlet 35, two branch channels 37, two first flow limiting blocks 312 and two second flow limiting blocks 313.

[0062] The Venturi inlet 34, the main stream, the outlet 35, and the two branch streams all protrude from the first surface 311. The inlet channel 11 of the water outlet device body 1 is connected to the Venturi inlet 34 of the water outlet component 3. In this embodiment, the Venturi inlet 34 has an inlet that gradually narrows along a first direction.

[0063] The main channel includes a main channel 36, two first bends 331, and two second bends 332. The main channel 36 is located downstream of the Venturi inlet 34.

[0064] Two first bends 331 are formed on both sides of the main channel 36. The distance between the two first bends 331 gradually increases in the direction away from the Venturi inlet 34, and both are concave outward from each other so that the main water flow from the Venturi inlet 34 into the main channel 36 flows along either of the first bends 331 and forms a circulating water vortex near the other first bend 331.

[0065] Two second bends 332 are formed on both sides of the main channel 36. Each second bend 332 is closer to the outlet 35 than the corresponding first bend 331 and is connected to the corresponding first bend 331. The distance between the two second bends 332 gradually increases in the direction away from the Venturi inlet 34, and both protrude toward the outlet.

[0066] The water outlet 35 has a water outlet. The inner wall of the water outlet is arranged along the extension path of the first curved section 331 to guide the main water flow along the first curved section 331 out of the water outlet. In this embodiment, the water passage area of ​​the water outlet gradually decreases in the direction away from the Venturi inlet 34, making the inner wall of the water outlet a slope, which better guides the main water flow along the first curved section 331 out of the water outlet. The distance (first distance d1) from the adjacent point of each first curved section 331 and second curved section 332 to the central axis surface A1 of the water outlet is less than the maximum distance (second distance d2) from the inner wall of the water outlet to the central axis surface A1 of the water outlet, so that the inner wall of the water outlet can catch the water flowing from the main channel 36 along the first curved section 331 to the water outlet, which helps to form a circulating water vortex and is more conducive to realizing periodically alternating pulsed water. In this embodiment, the central axis surface A1 is perpendicular to the second direction. The ratio of the water passage area of ​​the outlet to the water passage area of ​​the Venturi inlet 34 is 1.5-2, ensuring that the pressure of the water flowing into the branch channel 37 impacting the main channel 36 is within a reasonable range, neither too high nor too low. The outlet channel 123 of the water outlet device is connected to the outlet. One branch channel 37 is located outside a first bend section 331, and another branch channel 37 is located outside another first bend section 331. Each branch channel 37 has an inlet section 372 located between the outlet 35 and the first bend section 331, and an outlet section 374 located between the Venturi inlet 34 and the main channel. Each inlet section 372 connects the main channel 36 and the corresponding outlet section 374, allowing a portion of the water flowing from the main channel 36 to enter the corresponding branch channel 37 to form a branch flow. Each second curved section 332 forms a sidewall of the corresponding inlet section 372, and the spacing between the second curved sections 332 gradually increases along the direction away from the Venturi inlet section 34, and both protrude towards the outlet to guide part of the water flow from the main channel 36 into the corresponding inlet section 372, making the water flow smoother. The outlet section 374 is configured to guide the branch water flow towards the main water flow. In this embodiment, each branch channel 37 is also provided with a connecting section 373 connecting the corresponding inlet section 372 and the corresponding outlet section 374. The connecting section 373 extends along the first direction, and its two ends are respectively connected to the inlet section 372 and the outlet section 374. The inner wall of each inlet section 372 is provided with a recess 371 that is recessed away from the connecting section 373 to prevent the water flow from the main channel 36 entering the inlet section 372 from flowing back, and to guide the water flow to the connecting section 373. Each outlet section 374 includes a first section 3741 and a second section 3742. The first section 3741 connects the connecting section 373 and the second section 3742; the second section 3742 connects the main channel 36; the first section 3741 is an arc section to guide the water flow of the corresponding connecting section 373 from the second section 3742 into the main channel 36.The ratio of the water flow area of ​​each branch channel 37 to the water flow area of ​​the Venturi inlet 34 is 0.4-0.6, which ensures that the pressure of the water flow entering the branch channel 37 impacting the main channel 36 is within a reasonable range, neither too high nor too low.

[0067] In one exemplary embodiment, such as Figure 5 and Figure 7 As shown, the first surface 311 is inclined so that the water depth of the Venturi inlet 34, the main channel 36, the outlet 35 and the two branch channels 37 gradually increases along the direction from the Venturi inlet 34 to the outlet 35. This arrangement ensures that when multiple outlet components 3 are installed together, the water flowing out from each outlet is not only multiple pulsed water, but also the multiple pulsed water flows intertwine with each other, resulting in a larger water outlet range.

[0068] like Figures 5 to 7 As shown, each first flow-limiting block 312 is located between the corresponding second bend section 332 and the recess 371 to limit the flow rate from the main channel 36 into the inlet section 372. In this embodiment, by changing the water-passing area of ​​the inlet section 372, the flow rate into the branch channel 37 can be adjusted, thereby adjusting the oscillation frequency of the pulsed water. By setting the first flow-limiting blocks 312 respectively between the corresponding second bend section 332 and the recess 371, when the water flow is guided from the second bend section 332 and the recess 371 into the corresponding inlet section 372, the water-passing area is reduced due to the presence of the first flow-limiting blocks 312, thus controlling the flow rate into the branch channel 37 to adjust the oscillation frequency of the pulsed water. In this embodiment, by setting the first flow-limiting blocks 312, when it is necessary to adjust the oscillation frequency in actual use, the size of the first flow-limiting blocks 312 in the mold can be modified, making mold repair easier.

[0069] Two second flow-limiting blocks 313 are disposed between the venturi inlet 34 and the main flow section, respectively limiting the flow rate of each outlet section 374. The second flow-limiting blocks 313 can adjust the flow rate of the branch channels 37, thereby regulating the oscillation frequency of the pulsed water. In this embodiment, by setting the second flow-limiting blocks 313, when the oscillation frequency needs to be adjusted in actual use, the size of the second flow-limiting blocks 313 in the mold can be modified, making mold modification easier.

[0070] In one exemplary embodiment, the sidewalls of the first flow limiting block 312 and the second flow limiting block 313 are smooth curved surfaces to guide water flow into the corresponding inlet section 372 and out of the corresponding outlet section 374, respectively, thus preventing water backflow caused by the first and second limiting blocks. Each first flow limiting block 312 and each second flow limiting block 313 is a cylinder protruding from the first surface 311.

[0071] like Figures 5 to 7As shown, the main body 31 of the water outlet 3 extends along a first direction, and a first surface 311 is formed on one side wall perpendicular to the first direction. Two first protrusions 32 and two second protrusions 33 are protruding from the first surface 311. The two first protrusions 32 and the first surface 311 enclose a Venturi inlet 34, a water passage cavity, and a water outlet 35 arranged along the first direction. The two first protrusions 32 are symmetrically arranged along the central axis surface A1 of the water outlet 35, and the central axis surface A1 is parallel to the first direction. The two second protrusions 33 are located within the water passage cavity and are symmetrically arranged along the central axis surface A1. The water passage cavity is divided into a main channel 36 located in the middle and two branch channels 37 located on both sides of the main channel 36 and arranged along a second direction. The first side walls of the two second protrusions 33 located on both sides of the main channel 36 along the second direction cooperate with the main channel 36 to form the main channel section. A first curved section 331 and a second curved section 332 are provided on the first side wall.

[0072] The Venturi inlet 34, main channel 36, branch channel 37, and outlet 35 of the aforementioned water outlet structure are all configured to have openings in the third direction D3. When placed within the receiving cavity 122, the openings of the Venturi inlet 34, main channel 36, branch channel 37, and outlet 35 in the third direction D1 are sealed by the cavity wall of the receiving cavity 122. This configuration facilitates the processing of the water outlet 3 or the water outlet assembly 2. In other embodiments, the Venturi inlet 34, main channel 36, branch channel 37, and outlet 35 may not have openings in the third direction D1.

[0073] In one exemplary embodiment, the process by which the water outlet element of the aforementioned embodiment generates periodically alternating pulsed water is as follows:

[0074] like Figures 5 to 10 As shown, the main channel 36 is located downstream of the Venturi inlet 34, so the water flowing into the Venturi inlet 34 enters the main channel 36. Because two first bends 331 are provided on both sides of the main channel 36, due to the wall adhesion effect, most of the water flowing into the main channel 36 flows along either of the first bends 331, while a circulating vortex is formed at the other bend, such as... Figure 8 As shown. (Here, it is assumed that the attached image is pasted first.) Figure 8 The flow occurs in the first bend section 331 on the right, while a circulating vortex forms in the area of ​​the main channel 36 near the first bend section 331 on the left. The following left and right sections refer to the adjacent... Figure 8As the circulating water vortex gradually expands to its maximum size, most of the water in the main channel 36 gets closer to the first bend 331 on the right and flows out of the outlet at the maximum bend angle to the left. During this process, a small portion of the water in the main channel 36 enters the branch channels 37 through the inlet sections 372, forming a branch flow, and then flows from the outlet sections 374 of the branch channels 37 towards the main channel 36, impacting the water in the main channel 36. Since most of the water in the main channel 36 is close to the first bend 331 on the right, more water enters the left branch channel 37 than the right branch channel 37, and the water from the left branch channel 37 impacting the main channel 36 dominates.

[0075] like Figure 9 As shown, with the flow of water, the circulating vortex gradually moves to the left, reducing the amount of water entering the left branch channel 37 and causing the circulating vortex to shrink continuously. Meanwhile, another circulating vortex forms between the main channel 36 and the first bend section 331 on the right, resulting in two circulating vortices within the main channel 36. Consequently, the amount of water entering the right branch channel 37 gradually increases, leading to a gradual increase in the flow rate of water impacting the main channel 36 from the right branch channel 37. This causes the flow rates of water impacting the main channel 36 from the left and right branch channels 37 to become increasingly similar until they roughly cancel each other out. At this point, the water in the main channel 36 flows out of the outlet in a roughly direct current.

[0076] Although the water flows from the left and right tributaries 37 into the main channel 36 largely cancel each other out, the two circulating vortices still maintain their increasing or decreasing trends. At this time, the left circulating vortex continues to decrease, while the right circulating vortex continues to increase. As the water flows, the amount of water entering the right tributary 37 continuously increases, thus increasing the amount of water impacting the main channel 36 from the right tributary 37 until it exceeds the impact of the left tributary on the main channel 36. At this point, as... Figure 10 As shown, most of the water in the main channel 36 is pushed to the left by the circulating vortex on the right until it adheres to the first curved section 331 on the left due to the wall effect. At this point, the circulating vortex on the left disappears, and the circulating vortex on the right expands to its maximum size. The water in the main channel 36 flows to the right out of the outlet at the maximum curvature angle. As the water flows, the water in the outlet 3 gradually moves away from the first curved section 331 on the left in the same way until it adheres to the first curved section 331 on the right. By repeating the above process, the water flowing out of the outlet 3 is a periodically alternating pulse of water.

[0077] The inner wall of the outlet is set on the extension path of the first curved section 331 to guide the main water flow along the first curved section 331 to flow out of the outlet, so that the water flowing out of the outlet will not be dispersed by the inner wall of the outlet.

[0078] The Venturi inlet 34 accelerates the water flow into the main channel 36, enabling it to adhere to the wall more quickly and thus helping to form a circulating water vortex, which in turn helps to achieve periodic alternating pulsed water.

[0079] In one exemplary embodiment, the water outlet device is installed as follows: Figures 1 to 4 As shown, firstly, each of the three sets of water outlet components is inserted into the receiving cavity 122 of the water outlet body 12, so that the water outlet channel 123 is connected to the water outlet on each of the three water outlet components. Next, the upper cover 13 is placed on the water outlet body 12, so that the water inlet channel 11 is connected to the water inlet on each of the three water outlet components. Then, the water inlet channel 11 of the water outlet device is connected to an external water source.

[0080] In one exemplary embodiment, the water outlet device is used as follows:

[0081] like Figures 1 to 10 As shown, when water flows through the inlet channel 11, the water enters each receiving cavity 122 and then enters the Venturi inlet 34 on the outlet component 3 corresponding to the receiving cavity 122, forming a pulsed water flow that exits through the outlet and then flows out of the outlet channel 123. Figure 4 As shown, the pulsed water generated by the water outlet 3 in each accommodating cavity 122 is also inclined towards the adjacent water outlet 3 so that the two pulsed water streams intersect. Therefore, the two water streams flowing out of the outlet channel 123 from the outlets on each group of water outlets 3 not only oscillate in the second direction, but also incline towards the adjacent water outlet 3, so that the two water streams intersect and merge to form a pulsed water with a wider outlet range. The pulsed water generated on each water outlet 3 flows out from the corresponding outlet channel 123. Each accommodating cavity 122 has multiple water outlets 3, which can also increase the water output.

[0082] In one exemplary embodiment, the water outlet device includes a first water outlet body and a second water outlet body. When the first and second water outlet bodies are joined, they enclose each other to form a water inlet channel and at least one water outlet structure as described in any of the above embodiments. The water inlet channel and the Venturi water inlet portion 34 of the water outlet structure are connected.

[0083] When the first and second water outlet bodies are joined, they can form a water outlet structure as described in any of the above embodiments. The structure of the first water outlet is based on the water outlet 3 in any of the above embodiments, with an additional water inlet channel extending along the first direction D1 and communicating with the Venturi water inlet 34 added to the top of the water outlet 3. This water inlet channel also has an opening in the third direction D3. The structure of the second water outlet is configured to join with the first water outlet and to close the water inlet channel, the Venturi water inlet 34, the main channel 36, the branch channel 37, and the water outlet 35. When the first and second water outlet bodies are joined, the water outlet device can generate periodically alternating pulse water, and the pulse water also tilts with the tilt of the first surface 311. It should be understood that in other examples, the first flow limiting block 312, the second flow limiting block 313, the first protrusion 32, and the second protrusion 33 on the first water outlet body can also be all or partly provided on the second water outlet body. As long as the first and second water outlet components can be combined to form a water inlet channel and at least one water outlet structure, the specific structure can be changed according to the requirements.

[0084] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
