[0001] The present invention relates to the field of sanitation, and more particularly to a water flow regulating device.

Background Art

[0002] Conventionally, sanitary products such as multifunctional foaming devices and showers generally adopt forms such as screw adjustment or pressing adjustment to change the water discharge state, change the communication relationship in the water passage, and generate different water discharge shapes.

[0003] Generally, such products adjust the water flow by installing a water discharge net at the water discharge end to generate different water discharge shapes. However, when the water discharge net is used for a long time, it is likely to be adhered with scale or blocked by contaminants, resulting in non-smooth water discharge or deformation of the water shape in sanitary products. To solve the above technical problems, generally, it is necessary to remove the sanitary product and clean the water discharge net with a cleaning agent or other cleaning tools. However, conventional multifunctional sanitary products are generally relatively complex. In addition, in order to ensure the integrity of the product appearance, an integrated housing is generally provided on the outer surface of the multifunctional sanitary product, which increases the difficulty of detaching the water discharge net, and thus makes it difficult for users to clean the water discharge net in daily life.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The technical problem to be solved by the present invention is to provide a water flow regulating device that reduces the difficulty of cleaning the water discharge net.

Means for Solving the Problems

[0005] To solve the above technical problems, the technical means adopted by the present invention are as follows. The water flow adjustment device includes a water outlet and a water outlet panel that is reversibly connected to the water outlet. The water discharge body has a water discharge space, the water discharge space has a water outlet, and the water outlet has an inner diameter smaller than the maximum diameter of the water discharge panel. The water outlet is provided with an escape opening, and since the minimum distance from the escape opening to the axis of the water outlet is greater than the radius of the water outlet, the water outlet panel can be inserted into or removed from the water outlet through the escape opening. [Effects of the Invention]

[0006] The beneficial effects of the present invention are as follows: The water flow adjustment device according to the present invention has an inner diameter where the water outlet is installed that is smaller than the maximum diameter of the water outlet panel, so that the position of the water outlet panel within the water outlet body can be maintained, and by providing an escape port, an escape space is provided for inserting the water outlet panel into or removing it from the water outlet. The water outlet body does not have a deformation space, or the deformation space is extremely small, so that the water outlet panel can be attached and detached quickly, reducing the difficulty of attaching and detaching the water outlet panel, improving the possibility of cleaning the water outlet mesh surface, and extending the effective service life of the water flow adjustment device overall.

[0008] To explain in detail the technical content, objectives, and effects of the present invention, the embodiments will be described below with reference to the drawings.

[0009] Referring to Figures 1 to 10, the water flow adjustment device includes a water discharge body 1 and a water discharge panel 2 that is reversibly connected to the water discharge body 1. The water discharge panel 2 filters out impurities and adjusts the water flow. The water discharge body 1 has a water discharge space 11, which has a water outlet 12. The inner diameter of the water outlet 12 is smaller than the maximum diameter of the water discharge panel 2, and a bypass opening 13 is provided in the water outlet 12, allowing the water discharge panel 2 to be inserted through the bypass opening 13 or removed from the water outlet 12. Under the above conditions, the water discharge body 1 and the water discharge panel 2 are not limited to being made of elastic or rigid materials, and the water discharge panel 2 can be applied to a wider variety of situations.

[0010] It is understandable that the present invention provides a clearance opening 13 to allow the water discharge panel 2 to be fitted into or detached from the water discharge port 12, enabling rapid attachment and detachment of the water discharge panel 2 when the water discharge body 1 has no deformation space or only a very small deformation space, thereby reducing the difficulty of attaching and detaching the water discharge panel 2. In particular, the inner diameter of the water discharge port 12 is smaller than the maximum diameter of the water discharge panel 2. This is so that the point of the maximum diameter of the water discharge panel 2 is always located on one side away from the water discharge port 12 in the water discharge space 11. Furthermore, the water discharge panel 2 maintains stability even when subjected to the impact of the water flow, does not detach from the water discharge space 11, and consequently, not only can the water discharge panel 2 be rapidly attached and detached, but it can also be ensured to be in a relatively stable positional relationship with the water discharge body 1 during normal use. Compared to the prior art, overall attachment and detachment is not required; only the removal of the water discharge panel 2 from or insertion into the water discharge body 1 is necessary. When attaching or detaching the unit, only manual operation is required, without the need for other tools. This significantly reduces the difficulty of cleaning the water discharge panel 2, while maintaining excellent water discharge performance and extending the effective service life of the water discharge device.

[0011] In some embodiments, the avoidance opening 13 gradually recesses in the radial direction of the water outlet 12 in the direction opposite to the water discharge direction. The avoidance opening 13 has a shape similar to an arc in the axial cross-sectional view of the water outlet 1 and serves to guide the insertion of the water outlet panel 2.

[0012] In some embodiments, the minimum distance from the avoidance opening 13 to the axis of the water outlet 12 is greater than the radius of the water outlet 12. The avoidance opening 13 is provided with sufficient clearance space for removing or inserting the water outlet panel 2.

[0013] In some embodiments, referring to Figure 5, the length of the avoidance opening 13 in the circumferential direction of the water outlet 12 is greater than or equal to the axial thickness of the water outlet panel 2. This provides sufficient clearance space for removing or inserting the water outlet panel 2, ensuring smoothness in the process of removing or inserting the water outlet panel 2. Preferably, the difference between the length of the avoidance opening 13 and the axial thickness of the water outlet panel 2 is 0.2 mm to 1 mm, and it is preferable that the difference in thickness be 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm. The larger the length of the avoidance opening 13, the less difficult it is to align the water outlet panel 2 with the avoidance opening 13. It is possible to remove or insert the water outlet panel 2 without rotating it to a position where it is not directly facing the avoidance opening 13. On the other hand, the smaller the length of the avoidance opening 13, the higher the requirement for precision in aligning the water outlet panel 2 with the avoidance opening 13. Furthermore, the fitting 14 also increases the securing force to the water outlet panel 2, making it more difficult to remove or insert the water outlet panel 2.

[0014] In some embodiments, as shown in Figure 4, there is a fitting 14 located close to the avoidance port 13 in the discharge space 11. When the discharge panel 2 is inserted through the avoidance port 13 or disengaged from the discharge port 12, the discharge panel 2 is transiently combined with the fitting 14. Transient combination of the fitting 14 with the discharge panel 2 includes three cases. First, the maximum diameter of the discharge panel 2 is greater than the diameter of the fitting 14. Second, the maximum diameter of the discharge panel 2 is less than the diameter of the fitting 14. Third, the diameter of the discharge panel 2 is equal to the diameter of the fitting 14. Of these, when the diameter of the discharge panel 2 is less than or equal to the diameter of the fitting 14, the difference between the diameter of the discharge panel 2 and the diameter of the fitting 14 is 0 to 0.5 mm. Furthermore, when the difference between the diameter of the water discharge panel 2 and the diameter of the fitting 14 is 0 to 0.4 mm, under the same conditions, when the water discharge panel 2 is removed from or fitted into the water discharge space 11, the water discharge space 11 does not deform into the fitting 14, and the water discharge panel 2 can be smoothly removed from a position facing the avoidance opening 13. On the other hand, when the diameter of the water discharge panel 2 is larger than the diameter of the fitting 14, the difference between the diameter of the water discharge panel 2 and the diameter of the fitting 14 should be 0.1 mm or less. Under the same conditions, when the water discharge panel 2 is removed from or fitted into the water discharge space 11, the water discharge space 11 undergoes slight deformation into the fitting 14, and since the difference in diameter between the two is 0.1 mm or less, the requirement for deformation space is relatively low. In this case, whether rigid or elastic materials are used for the water discharge panel 2 and the water discharge body 1, the water discharge panel 2 can be removed from or fitted into the water discharge body 1. However, it is preferable to select a diameter for the water outlet panel 2 such that it fits within the diameter of 14 or less.

[0015] In some embodiments, the thickness of the fitting 14 in the axial direction of the water discharge body 1 is 0.2 mm to 1.2 mm. Furthermore, the thickness of the fitting 14 is 0.4 mm to 0.8 mm. Fittings 14 within this thickness range have excellent deformation performance. Moreover, the thinner the thickness of the fitting 14, the stronger its deformation performance becomes. The thickness of the fitting 14 may be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, or 0.75 mm.

[0016] In some embodiments, the difference value between the diameter of the accommodation 14 and the maximum diameter of the water ejection panel 2 is 0.1 mm to 1 mm. In this embodiment, the difference value is 0.2 mm to 0.8 mm. Preferably, the difference value may be 0.25 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm or 0.75 mm. Specifically, in some embodiments, the maximum diameter of the water ejection panel 2 is 12 mm to 30 mm.

[0017] In some embodiments, only one avoidance port 13 is provided. Alternatively, referring to FIGS. 1 to 5, at least two avoidance ports 13 are provided, and when at least two avoidance ports 13 are provided, the two avoidance ports 13 are arranged symmetrically with respect to the radial direction of the water ejection port 12. That is, when the water ejection panel 2 faces any two avoidance ports 13 arranged symmetrically in the radial direction as shown in FIGS. 1 to 3, the removal or insertion becomes smooth. When only one avoidance port 13 is provided, the requirement for the size of the accommodation 14 is further increased, and there should be a position for detaching and attaching the water ejection panel 2 between the position where the avoidance port 13 is located and the inner wall of the water ejection space 11. When at least two avoidance ports 13 are provided, it is preferable to install two avoidance ports 13 as a group for each avoidance port 13, and to arrange the two avoidance ports 13 in each group symmetrically with respect to the radial direction of the water ejection port 12. In this case, the requirement for the diameter size of the accommodation 14 is reduced, the difficulty of detaching and attaching the water ejection panel 2 is also the lowest, and a plurality of avoidance ports 13 may be set according to the thickness sizes of the water ejection port 12 and the water ejection panel 2. <�

[0018] In some embodiments, the ratio between the axial thickness of the water outlet panel 2 and the diameter of the water outlet 12 is 0.1 to 0.7. Preferably, the proportional range is 0.167 to 0.5, and the proportional range may be 0.2, 0.25, 0.26, 0.27, 0.28, 0.29, 0.3, 0.31, 0.32, 0.33, 0.34, 0.35, 0.36, 0.37, 0.4, or 0.45. If the water discharge panel 2 is too thick, and the axis of the water discharge panel 2 and the axis of the water outlet 12 are perpendicular to each other, the distance between the water passage surface of the water discharge panel 2 and the side wall of the water outlet 12 will be too small. This will prevent the user from directly inserting their fingers into the notch 15 formed between the water discharge panel 2 and the water outlet 12 to remove the water discharge panel 2. Consequently, separating the water discharge panel 2 from the water discharge body 1 will become difficult, and removal will not be possible without tools such as needle-nose pliers. If the water discharge panel 2 is too thin, the contact area between the water discharge panel 2 and the seal ring will be too small. Consequently, the water discharge panel 2 will become unstable when subjected to impact from the water flow, and will not be able to maintain a state in which the water discharge panel 2 and the water discharge body 1 are coaxial. Therefore, if the axial thickness of the water discharge panel 2 and the diameter of the water outlet 12 are limited to the same numerical range, the water discharge panel 2 can be removed, and relative stability can be maintained even when subjected to impact from the water flow.

[0019] In some embodiments, referring to FIGS. 4, 9 and 10, there is a support portion 4 that abuts against the water discharge panel 2 in the water discharge space 11. When the water discharge panel 2 is inserted into the water discharge port 12, the contact between the water discharge panel 2 and the water discharge body 1 mainly depends on the support portion 4. Installing the support portion 4 ensures the sealing performance between the water discharge panel 2 and the inner wall of the water discharge space 11, while providing radial support to the water discharge panel 2 and a fulcrum for the rotation of the water discharge panel 2. When the water discharge panel 2 is fitted into the water discharge space 11, it can be ensured to maintain stability. When the water discharge panel 2 receives the pressure from the water pressure in the water discharge direction, while contacting the side wall at the water discharge port 12, it can also apply a force in the opposite direction to the water discharge panel 2 from the circumferential side wall where the diameter at the water discharge port 12 is smaller than the diameter of the water discharge panel 2, and can maintain the connection position between the water discharge panel 2 and the support portion 4.

[0020] In some embodiments, the support portion 4 and the water discharge space 11 are integrally formed, or the support portion 4 is a sealing ring installed separately from the water discharge space 11. When the support portion 4 and the water discharge space 11 are integrally formed, the support portion 4 maintains a positional relationship of being relatively stationary with the water discharge space 11 as a part of the water discharge space 11. The elasticity and size of the support portion 4 cannot be selected, and the limitation is relatively large. On the other hand, when the support portion 4 is a sealing ring installed separately from the water discharge space 11, the sealing performance between the support portion 4 and the water discharge panel 2 is enhanced, and moreover, the size and elasticity of the support portion 4 can be selected flexibly, so that the water discharge panel 2 can be located at an optimal position and excellent stability can be obtained.

[0021] In some embodiments, when the inner diameter of the support portion 4 is larger than the maximum diameter of the water discharge panel 2, and the water discharge panel 2 and the water discharge body 1 are coaxially installed and completely cover the water discharge port 12, the location of the maximum diameter of the water discharge panel 2 is on one side away from the water discharge port 12 in the support portion 4. The limitation under the above conditions mainly restricts the position of the water discharge panel 2 in the water discharge space 11 when the water discharge panel 2 is inserted into the water discharge space 11, that is, even when the water discharge panel 2 is subjected to the impact of the incoming water flow, it can maintain a relatively stable positional relationship.

[0022] In some embodiments, referring to Figure 9, the water discharge panel 2 has a first water passage means 21 and a second water passage means 22, and the water discharge panel 2 is provided with a water inlet 23 on its circumferential side wall that communicates simultaneously with the first water passage means 21 and the second water passage means 22. When the water discharge panel 2 and the water discharge body 1 are installed coaxially, the water inlet 23 is located on one side of the support part 4 away from the water discharge port 12. When the water discharge panel 2 and the water discharge body 1 are installed coaxially, if the first water passage means 21 is used as the water supply surface, a portion of the water flow first passes through the water passage holes of the first water passage means 21 before entering the interior of the water discharge panel 2, while another portion of the water flow flows into the interior of the water discharge panel 2 from the water inlet 23, and the water flow from both parts collects inside the water discharge panel 2 before flowing out from the second water passage means 22. Since the water discharge panel 2 is reversibly connected to the water discharge body 1, either the first water passage means 21 or the second water passage means 22 may be used as the water supply surface. Whether it is the first water passage means 21 or the second water passage means 22, if it is a water supply surface, a portion of the water flow enters the discharge panel 2 from the water inlet 23, while other portions of the water flow may collect with it before flowing out. Therefore, the main purpose of installing the water inlet 23 is to ultimately increase the flow rate of the water flow that is output to the outside from the water passage means as a discharge surface.

[0023] It is understandable that the first water passage means 21 and the second water passage means 22 may be two different components, or they may have completely different discharge configurations or discharge mesh surfaces. In this case, different water patterns can be formed when the first water passage means 21 or the second water passage means 22 is used as a discharge surface. Because the different discharge configurations / discharge mesh surfaces have different water passage areas, the input flow rate obtained from the water passage means with the other as the discharge surface will be different when each is used as a water supply surface. For example, as shown in Figures 7 and 8, the first water passage means 21 has a mesh-like discharge mesh, and the discharge configuration of the second water passage means 22 consists of small water passage holes installed without gaps, so the flow area of ​​the first water passage means 21 is clearly much larger than the flow area of ​​the second water passage means 22. Therefore, when the first water passage means 21 is used as a water supply surface, the flow rate from the first water passage means 21 into the discharge panel 2 is relatively large. When the second water passage means 22 is used as the water supply surface, the flow rate from the second water passage means 22 into the water discharge panel 2 is relatively small. Therefore, when the second water passage means 22 is used as the water supply surface and the first water passage means 21 is used as the water discharge surface (i.e., the configuration shown in Figure 7), the first water passage means 21 will not receive a sufficient input flow rate, making it difficult to form the desired shape of the output water flow (insufficient flow rate), thus failing to meet the requirements for using that water flow. In other possible designs, a certain water passage means may have fewer than 10 discharge holes to output only one or more water columns with extremely high water pressure. When this water passage means is used as the water supply surface, it is easy to anticipate how small the input flow rate obtained from other water passage means acting as the water discharge surface will be. In the cases described above, it is essential to install a water inlet 23. This provides a boost to the flow rate and supports the need for high-flow output from the water passage means acting as the water discharge surface.

[0024] In some embodiments, referring to Figures 9 and 10, a water supply passage 3 communicating with a water inlet 23 is formed between the water discharge panel 2 and the inner wall of the water discharge space 11. The purpose of forming the water supply passage 3 is to divide the water flow, thereby ensuring that a portion of the water flow flows from the water inlet 23 to the water discharge panel 2, and that the water pressure received on the water supply surface of the water supply panel is kept low.

[0025] In some embodiments, the circumferential side walls of the water outlet panel 2 and the inner walls of the water outlet space 11 are spherical or polygonal prism surfaces. Of these, the spherical surfaces include perfect spheres and imperfect spheres. When the circumferential side walls of the water outlet panel 2 are perfect spheres, in the axial cross-sectional view of the water outlet panel 2, the circumferential side walls of the water outlet panel 2 form an arc, and the distance between each point on the arc and the three-dimensional center point of the water outlet panel 2 are both equal. An imperfect sphere is one in which, in the axial cross-sectional view of the water outlet panel 2, the circumferential side wall contour of the water outlet panel 2 is an arc or a combination of an arc and a straight line, but the radius between each point on the arc and the radius of the three-dimensional center point of the water outlet panel 2 are not equal. A polygonal prism is one in which, in the axial cross-sectional view of the water outlet panel 2, the circumferential side wall contour of the water outlet panel 2 is a combination of multiple straight lines. Correspondingly, the water discharge space 11 is one of a perfect sphere, an imperfect sphere, or a polygonal prism. The optimal choice is for the water discharge space 11 to be a perfect sphere. In order for the water discharge panel 2 to rotate smoothly in the water discharge space 11, the circumferential side walls of the water discharge panel 2 are perfectly spherical. Correspondingly, the water discharge space 11 is also perfectly spherical. The difference lies in the size of the inner walls of the water discharge panel 2 and the water discharge space 11. Specifically, in order to ensure that the water discharge panel 2 is always in contact with the support part 4 even when subjected to impact from the water flow when fitted into the water discharge space 11, in some embodiments, when the axis of the water discharge panel 2 and the axis of the water outlet 12 are perpendicular to each other, the axis of the water discharge panel 2 is located on one side away from the water outlet 12 in the support part 4, and the point of the maximum diameter of the water discharge panel 2 is always located on one side away from the water outlet 12 in the water discharge space 11.

[0026] In some embodiments, friction-enhancing portions 5 are installed on at least one surface of the water discharge panel 2 in the axial direction. Preferably, friction-enhancing portions 5 are installed on one or both surfaces of the water discharge panel 2n in the axial direction. Specifically, the friction-enhancing portions 5 may be protrusions installed around the periphery of the surface of the water discharge panel 2, or protrusions installed at intervals around the periphery of the surface of the water discharge panel 2, or a water discharge mesh with a relatively high frictional force may be installed on the surface of the water discharge panel 2.

[0027] Referring to Figures 1 to 5, the first embodiment of the present invention is as follows. The water flow adjustment device includes a water discharge body 1 and a water discharge panel 2 that is reversibly connected to the water discharge body 1. The water discharge body 1 has a water discharge space 11, which has a water outlet 12. The inner diameter of the water outlet 12 is smaller than the maximum diameter of the water discharge panel 2, and the water outlet 12 is provided with two symmetrically arranged escape openings 13, which allows the water discharge panel 2 to be inserted through the escape openings 13 or removed from the water outlet 12.

[0028] In this embodiment, referring to Figure 4, the avoidance port 13 gradually recesses in the radial direction of the water outlet 12, along a direction opposite to the water discharge direction.

[0029] In this embodiment, referring to Figure 5, the length W of the bypass opening 13 in the circumferential direction of the water outlet 12 is greater than the axial thickness w of the water outlet panel 2, and the difference is 0.4 mm. Of these, the axial thickness w of the water outlet panel 2 refers to the distance between the end face of the first water passage means 21 and the end face of the second water passage means 22.

[0030] In this embodiment, the water discharge space 11 has a fitting 14 located close to the avoidance opening 13, and when the water discharge panel 2 is inserted through the avoidance opening 13 or removed from the water discharge opening 12, the water discharge panel 2 is transiently combined with the fitting 14.

[0031] In this embodiment, the thickness g of the fitting 14 in the axial direction of the water discharge body 1 is 0.55 mm, 0.6 mm, or 0.65 mm.

[0032] In this embodiment, the diameter k of the fitting 14 is larger than the maximum diameter D of the water outlet panel 2, and the difference between the diameter k of the fitting 14 and the maximum diameter d of the water outlet panel 2 is 0.4 mm. In other embodiments where they are equal, the diameter k of the fitting 14 may be equal to the maximum diameter D of the water outlet panel 2, or it may be smaller than the maximum diameter D of the water outlet panel 2. When the diameter k of the fitting 14 is smaller than the maximum diameter D of the water outlet panel 2, the difference between the two is less than 0.1 mm. Among these, the maximum diameter D of the water outlet panel 2 is between 12 mm and 30 mm.

[0033] In this embodiment, the ratio between the axial thickness w of the water outlet panel 2 and the diameter d of the water outlet 12 is 0.344. When the axis of the water outlet panel 2 and the axis of the water outlet 12 are perpendicular to each other, the maximum distance t between the water outlet panel 2 and the water outlet 12 is 4 mm to 15 mm. Referring to Figure 5, the maximum distance t between the water outlet panel 2 and the water outlet 12 refers to the maximum distance of the notch 15 formed between the water outlet panel 2 and the inner wall of the water outlet 12 in the radial direction of the water outlet 12, in the area projected in the axial direction of the water outlet 12.

[0034] In this embodiment, referring to Figures 4 and 9, the water discharge space 11 has a support portion 4 that contacts the water discharge panel 2 at a position close to the water discharge port 12. The support portion 4 is a seal ring installed separately from the water discharge space 11. Furthermore, the inner diameter of the position where the support portion 4 contacts the water discharge panel 2 is smaller than the maximum diameter of the water discharge panel 2. When the water discharge panel 2 and the water discharge body 1 are installed coaxially and the water discharge port 12 is completely covered, the point of the maximum diameter of the water discharge panel 2 is located on one side of the support portion 4 away from the water discharge port 12.

[0035] In this embodiment, as shown in Figure 4, both the circumferential side walls of the water discharge panel 2 and the inner walls of the water discharge space 11 are perfectly spherical.

[0036] In this embodiment, referring to Figure 4, friction-enhancing portions 5 are installed on both sides of the water discharge panel 2 in the axial direction. Specifically, the friction-enhancing portion 5 is an annular protrusion. The friction-enhancing portions 5 located on both sides of the water discharge panel 2 may have the same thickness or different thicknesses in the circumferential direction. In this embodiment, the two friction-enhancing portions 5 on the water discharge panel 2 have different thicknesses. The axial thickness of the friction-enhancing portion 5 is 0.1 mm to 1 mm. Preferably, the axial thickness of the friction-enhancing portion 5 is 0.3 mm, 0.4 mm, 0.5 mm, or 0.6 mm.

[0037] In this embodiment, referring to Figure 2, in order to reduce the difficulty of reversing the water discharge panel 2, reversal rods 6 are installed on both axial end faces of the water discharge panel 2, and the axial length of the reversal rods 6 is less than or equal to the maximum radius of the water discharge panel 2. When the water discharge panel 2 is squeezed by an external force or struck by a water flow, the water discharge panel 2 comes into contact with the inner wall of the water discharge space 11, so that the water discharge panel 2 is always located in the water discharge space 11.

[0038] In this embodiment, the operating principle is as follows.

[0039] When the water discharge device is in operation, the water discharge panel 2 and the water discharge body 1 are basically coaxial. The axes of the water discharge panel 2 and the water discharge body 1 may maintain a constant angle (for example, the angle formed by the axes of both is a combined angle of 15 degrees or less). The water flow output from the water discharge panel 2 is at a constant angle with respect to the water supply direction, and this angle coincides with the angle of the axes of both.

[0040] Referring to Figures 2 and 5, if it becomes necessary to remove and clean the water discharge panel 2, invert the water discharge panel 2 so that its axis and the axis of the water outlet 12 are perpendicular or nearly perpendicular, rotate the water discharge panel 2 around the water outlet so that the water discharge panel 2 faces the two escape ports 13 in the radial direction, and then grasp the two water passage end faces of the water discharge panel 2 with your hands and remove it in the direction of water discharge from the water discharge device. During this process, the support portion 4 is narrowed at the point of maximum diameter of the water discharge panel 2, resulting in a slight indentation.

[0041] The removed water outlet panel 2 may be cleaned of limescale and other contaminants by physical or chemical cleaning. Physical cleaning mainly involves using a cleaning tool to brush the mesh holes of the water outlet panel 2 to remove soft limescale and other contaminants that clog the holes. Chemical cleaning involves immersing the water outlet panel 2 in an acidic detergent to remove hard limescale in the water outlet holes or internal water passages of the water outlet panel 2.

[0042] Once cleaning is complete, position the water discharge panel 2 so that its axis and the axis of the water outlet 12 are perpendicular to each other, then align the water discharge panel 2 radially with the two escape ports 13. Push the water discharge panel 2 into the water discharge space 11 from the water outlet 12, and maintain the fit with the water discharge space 11 to complete the installation. Next, flip one side of the water discharge panel 2 (which should be selected depending on the desired water flow pattern) so that it covers the entire water outlet 12, and the water discharge device can then be used normally.

[0043] A second embodiment of the present invention is as follows. The difference between this embodiment and the first embodiment is that the water flow adjustment device has only one bypass port 13. In this embodiment, in order to ensure that the water discharge panel 2 can be smoothly removed from or fitted into the water discharge port 12, the minimum distance from the bypass port 13 to the axis of the water discharge port 12 is greater than the radius of the water discharge port 12, and the difference is 0.05 mm. This avoids deformation of the water discharge port 12 and reduces the difficulty of removing or fitting the water discharge panel 2. In the other embodiment where the spacing is equal, the minimum distance from the bypass port 13 to the axis of the water discharge port 12 is also smaller than the radius of the water discharge port 12, and the difference is less than 0.1 mm.

[0044] Referring to Figure 7 or Figure 10, a third embodiment of the present invention is as follows. In this embodiment, the water flow adjustment device is installed by setting up a water discharge panel 2 with a different configuration based on the first embodiment or the second embodiment.

[0045] In this embodiment, the water discharge panel 2 has a first water passage means 21 and a second water passage means 22, and the first water passage means 21 and the second water passage means 22 have different water discharge configurations / water discharge mesh surfaces to form the shape of the discharged water. The water discharge panel 2 is provided with a water inlet 23 on its circumferential side wall that communicates simultaneously with the first water passage means 21 and the second water passage means 22. When the water discharge panel 2 and the water discharge body 1 are installed coaxially, the water inlet 23 is located on one side away from the water discharge port 12 on the support part 4. When the water discharge panel 2 and the water discharge body 1 are installed coaxially, if the first water passage means 21 is used as the water supply surface, a portion of the water flow enters the interior of the water discharge panel 2 first through the first water passage means 21, and at the same time, another portion flows into the interior of the water discharge panel 2 from the water inlet 23. The water flow from both parts collects inside the water discharge panel 2 and then flows out from the second water passage means 22. One easily understandable aspect is that, since the water discharge panel 2 is reversibly connected to the water discharge body 1, both the first water passage means 21 and the second water passage means 22 can be used as water supply surfaces. Whether the first water passage means 21 or the second water passage means 22 is used as the water supply surface, a portion of the water flow enters the water discharge panel 2 from the water inlet 23, collects with another portion to replenish the flow rate, and then flows out from the water discharge surface.

[0046] In this embodiment, a water supply passage 3 communicating with the water inlet 23 is formed between the water discharge panel 2 and the inner wall of the water discharge space 11, and by designing the sizes of the water inlet 23 and the water supply passage 3 to correspond, it is possible to replenish water at different flow rates.

[0047] In this embodiment, the operating principle is as follows. Referring to Figure 10, when the first water passage means 21 is used as the water supply surface, the water flow simultaneously passes through the first water passage means 21, and then sequentially through the water supply passage 3 and the water inlet 23 before entering the water discharge panel 2, and finally passing through the second water passage means 22 before being discharged to the outside in a water shape. On the other hand, the water discharge panel 2 may be inverted. When the second water passage means 22 is used as the water supply surface, and either the first water passage means 21 or the second water passage means 22 is used as the water supply surface, the water discharged from the water discharge panel 2 has a different shape.

[0048] Based on the above, the water flow adjustment device provided by the present invention is installed such that the diameter of the outlet is smaller than the maximum diameter of the water discharge panel in order to ensure that the water discharge panel can always remain in the water discharge space even when subjected to impact from the water flow. In order to ensure that the water discharge panel is always engaged in the water discharge space when operating normally, a relief opening is provided at the outlet, and by rotating the water discharge panel to a position where it is directly facing the relief opening, it can be removed from or fitted into the water discharge space. This ensures the stability of the water discharge panel in the water discharge space and allows for rapid attachment and detachment of the water discharge panel. The ability to attach and detach the water discharge panel to the water discharge space has a broader range of applications, not limited to the rigidity of the water discharge space or the material of the water discharge panel.

[0049] The above description is merely an embodiment of the present invention and does not in any way limit the scope of the patent of the present invention. Any equivalent substitutions made based on the content described in the specification and drawings of the present invention, or any direct or indirect application of the related technical field, should similarly be included within the scope of patent protection of the present invention.
