Description

[0001] This divisional application is based on the mother patent of an invention patent with an application date of May 12, 2023, an application number of 2023105379884, and a title of "A Water Flow Shaper". Technical Field

[0002] The present invention relates to the field of sanitary ware, and particularly refers to a water flow shaper. Background Art

[0003] For existing sanitary ware products such as multifunctional bubblers and shower heads, in order to change the water outlet state, generally, the way of rotary adjustment or pressing adjustment is adopted to change the connection relationship of the water path, and then water outlet water flowers of different forms are generated.

[0004] An outlet net is usually arranged at the water outlet end of the above products to shape the water flow, so as to generate different water outlet water flowers. After long-term use, the outlet net is prone to scale adhesion or blockage by impurities, resulting in unsmooth water outlet of the sanitary ware product or deformation of the water flowers. To solve the above technical problems, it is usually necessary to disassemble the sanitary ware product and use a descaling agent and other cleaning tools to clean the outlet net. The structures of existing multifunctional sanitary ware products are generally complex, and in order to ensure the integrity of the appearance of the products, the appearance of multifunctional sanitary ware products generally has an integrated housing, which increases the difficulty of disassembling or installing the outlet net, and further makes it difficult for users to clean the outlet net during daily use. Summary of the Invention

[0006] To solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A water flow shaper includes a water outlet body and a water outlet panel reversibly connected to the water outlet body;

[0008] The water outlet body has a water outlet cavity, the water outlet cavity has a water outlet, and the inner diameter of the water outlet is smaller than the maximum diameter of the water outlet panel;

[0009] A relief opening is provided on the water outlet, and the minimum distance from the relief opening to the axis of the water outlet is greater than the radius of the water outlet, so that the water outlet panel can be embedded in or disengaged from the water outlet through the relief opening.

[0010] The beneficial effects of the present invention are as follows: the inner diameter of the water outlet of the water flow shaper of the present invention is set to be smaller than the maximum diameter of the water outlet panel, so that the position of the water outlet panel in the water outlet body can be maintained, and a clearance port is set to provide a clearance space for the water outlet panel to be embedded in or separated from the water outlet, so that when the water outlet body has no deformation space or the deformation space is extremely small, the water outlet panel can be quickly embedded or pulled out, reducing the difficulty of assembling and disassembling the water outlet panel, thereby improving the cleanability of the water outlet mesh surface, and extending the effective service life of the water flow shaper as a whole.

[0025] To describe the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the implementation modes and with reference to the drawings.

[0026] Please refer to Figures 1 - 10 , a water flow shaper, comprising a water outlet body 1 and a water outlet panel 2 that is rotatably connected to the water outlet body 1. Among them, the water outlet panel 2 is used to filter impurities and can rectify the water flow; the water outlet body 1 has a water outlet cavity 11, the water outlet cavity 11 has a water outlet 12, and the inner diameter of the water outlet 12 is smaller than the maximum diameter of the water outlet panel 2; a relief opening 13 is provided on the water outlet 12 so that the water outlet panel 2 can be inserted into or detached from the water outlet 12 through the relief opening 13. Under the above conditions, the materials of the water outlet body 1 and the water outlet panel 2 are not limited to elastic or rigid materials, so that the water outlet panel 2 can be applied to more situations.

[0027] It can be understood that the present invention provides a relief space for the water outlet panel 2 to be inserted into or detached from the water outlet 12 by setting the relief opening 13, so that when the water outlet body 1 has no deformation space or the deformation space is extremely small, the water outlet panel 2 can be quickly inserted or pulled out, reducing the assembly and disassembly difficulty of the water outlet panel 2; among them, the inner diameter of the water outlet 12 is smaller than the maximum diameter of the water outlet panel 2 in order to make the maximum diameter of the water outlet panel 2 always located on the side of the water outlet cavity 11 away from the water outlet 12, so that the water outlet panel 2 can remain stable when being impacted by the water flow and not detach from the water outlet cavity 11, thereby ensuring that the water outlet panel 2 can not only achieve quick assembly and disassembly, but also maintain a relatively stable positional relationship with the water outlet body 1 during normal use. Compared with the prior art, there is no need for overall disassembly and assembly, only the water outlet panel 2 needs to be pulled out or inserted from the water outlet body 1, and the disassembly and assembly process can even be completed without the aid of other tools only by manual operation, greatly reducing the cleaning difficulty of the water outlet panel 2, thereby maintaining the good water outlet effect of the water outlet device and prolonging the effective service life of the water outlet device.

[0028] In some embodiments, the relief opening 13 gradually depresses in the direction opposite to the water outlet direction in the radial direction of the water outlet 12. In the sectional view of the relief opening 13 in the axial direction of the water outlet body 1, the relief opening is in an arc-like shape, which is used to guide the insertion of the water outlet panel 2.

[0029] In some embodiments, the minimum distance from the relief opening 13 to the axis of the water outlet 12 is greater than the radius of the water outlet 12, which can form a relief space at the relief opening 13 sufficient for the water outlet panel 2 to be pulled out or inserted.

[0030] In some embodiments, referring to Figure 5 , in the circumferential direction of the water outlet 12, the length of the relief opening 13 is not less than the axial thickness of the water outlet panel 2, so as to provide sufficient relief space for the pulling out or inserting of the water outlet panel 2 and ensure the smoothness of the process of pulling out or inserting the water outlet panel 2. Optionally, the difference between the length of the relief opening 13 and the axial thickness of the water outlet panel 2 is 0.2 mm to 1 mm. Preferably, the thickness difference is 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or 0.9. If the length of the relief opening 13 is larger, the alignment difficulty between the water outlet panel 2 and the relief opening 13 is reduced, and the water outlet panel 2 can be pulled out or inserted without rotating the water outlet panel 2 to a position completely opposite to the relief opening 13; conversely, if the length of the relief opening 13 is smaller, the alignment accuracy requirement for the water outlet panel 2 and the relief opening 13 is higher, and the binding force of the closing opening 14 on the water outlet panel 2 is also greater, making it difficult for the water outlet panel 2 to be pulled out or inserted.

[0031] In some embodiments, referring to Figure 4 , the water outlet cavity 11 has a closing opening 14 near the relief opening 13. When the water outlet panel 2 is inserted into or detached from the water outlet 12 through the relief opening 13, the water outlet panel 2 is in transitional fit with the closing opening 14. The transitional fit between the closing opening 14 and the water outlet panel 2 includes three cases. One is that the maximum diameter of the water outlet panel 2 is greater than the diameter of the closing opening 14, the second is that the maximum diameter of the water outlet panel 2 is less than the diameter of the closing opening 14, and the third is that the diameter of the water outlet panel 2 is equal to the diameter of the closing opening 14. Among them, when the diameter of the water outlet panel 2 is less than or equal to the diameter of the closing opening 14, the difference between the diameter of the water outlet panel 2 and the diameter of the closing opening 14 is 0 to 0.5 mm. Further, the difference between the diameter of the water outlet panel 2 and the diameter of the closing opening 14 is 0 to 0.4 mm. Under this condition, when the water outlet panel 2 is pulled out or inserted into the water outlet cavity 11, the water outlet cavity 11 will not deform at the closing opening 14, and the water outlet panel 2 can be smoothly pulled out at a position opposite to the relief opening 13; when the diameter of the water outlet panel 2 is greater than the diameter of the closing opening 14, the difference between the diameter of the water outlet panel 2 and the diameter of the closing opening 14 should be less than or equal to 0.1 mm. Under this condition, when the water outlet panel 2 is pulled out or inserted from the water outlet cavity 11, the water outlet cavity 11 will undergo slight deformation at the closing opening 14. Since the difference between their diameters is less than or equal to 0.1 mm, the requirement for the deformation space is relatively low. At this time, whether the water outlet panel 2 and the water outlet body 1 are made of rigid or elastic materials, the water outlet panel 2 can be pulled out or inserted into the water outlet body 1, but the optimal choice is to make the diameter of the water outlet panel 2 less than or equal to the diameter of the closing opening 14.

[0032] In some embodiments, in the axial direction of the water outlet body 1, the thickness at the necking 14 is 0.2 mm to 1.2 mm. Further, the thickness at the necking 14 is 0.4 mm to 0.8 mm. The necking 14 within this thickness range has good deformation performance, and the thinner the thickness at the necking 14, the stronger its deformation performance. The thickness at the necking 14 can be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm or 0.75 mm.

[0033] In some embodiments, the difference between the diameter of the necking 14 and the maximum diameter of the water outlet panel 2 is 0.1 mm to 1 mm. In this embodiment, the difference is 0.2 mm to 0.8 mm. Preferably, the difference can 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 outlet panel 2 is 12 mm to 30 mm.

[0034] In some embodiments, there is one relief opening 13, or Figures 1 - 5 , there are at least two relief openings 13, and when there are at least two relief openings 13, every two relief openings 13 are symmetrically arranged in the radial direction of the water outlet 12, so that when the water outlet panel 2 is Figures 1 - 3 facing any two symmetrically arranged relief openings 13 in the radial direction as shown, it can be smoothly pulled out or inserted. When there is only one relief opening 13, the dimensional requirements for the necking 14 are higher. There should be a position between the position where the relief opening 13 is provided and the inner wall of the water outlet cavity 11 that can allow the water outlet panel 2 to be pulled out or inserted; while when there are at least two relief openings 13, the relief openings 13 are preferably arranged in groups of two, and the two relief openings 13 within each group are symmetrically arranged in the radial direction of the water outlet 12. At this time, the dimensional requirements for the diameter of the necking 14 are reduced, and the difficulty of pulling out or inserting the water outlet panel 2 is also the lowest. Multiple groups of relief openings 13 can be set according to the thickness dimensions of the water outlet 12 and the water outlet panel 2.

[0035] In some embodiments, the ratio of the axial thickness of the water outlet panel 2 to the diameter of the water outlet 12 is 0.1 to 0.7. Optionally, the ratio range is 0.167 to 0.5, and the ratio can 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 thickness of the water outlet panel 2 is too large, when the axis of the water outlet panel 2 is perpendicular to the axis of the water outlet 12, the distance between the water passing surface of the water outlet panel 2 and the side wall of the water outlet 12 is too small to accommodate the user's finger to directly insert into the notch 15 formed between the water outlet panel 2 and the water outlet 12 for the operation of pulling out the water outlet panel 2, which will increase the difficulty of separating the water outlet panel 2 from the water outlet body 1, and only tools such as a pointed-nose pliers can be used to achieve the disassembly operation. If the thickness of the water outlet panel 2 is too small, the contact area between the water outlet panel 2 and the sealing ring will be too small, resulting in poor stability of the water outlet panel 2 after being impacted by the water flow, and it is impossible to maintain the coaxial state of the water outlet panel 2 and the water outlet body 1. Therefore, the axial thickness of the water outlet panel 2 and the diameter of the water outlet 12 are limited within this numerical range, so that the water outlet panel 2 can be easily pulled out and can remain relatively stable with respect to the water outlet body 1 when impacted by the water flow.

[0036] In some embodiments, referring to Figure 4 、 Figure 9 and Figure 10 , there is a support portion 4 in the water outlet cavity 11 that abuts against the water outlet panel 2. When the water outlet panel 2 is inserted into the water outlet 12, the contact between the water outlet panel 2 and the water outlet body 1 mainly relies on the support portion 4. The support portion 4 is provided to ensure the sealing between the water outlet panel 2 and the inner wall of the water outlet cavity 11 on the one hand, and to provide radial support for the water outlet panel 2 and serve as the rotation fulcrum of the water outlet panel 2 on the other hand, to ensure the stability when the water outlet panel 2 is embedded in the water outlet cavity 11. When the water outlet panel 2 is subjected to the water pressure acting in the water outlet direction, it will contact the side wall at the water outlet 12, and the circumferential side wall with a diameter smaller than that of the water outlet panel 2 at the water outlet 12 exerts a reverse force on the water outlet panel 2, which can also keep the connection position between the water outlet panel 2 and the support portion 4.

[0037] In some embodiments, the support portion 4 is integrally formed with the water outlet cavity 11, or the support portion 4 is a sealing ring separately provided from the water outlet cavity 11. When the support portion 4 is integrally formed with the water outlet cavity 11, the support portion 4 is a part of the water outlet cavity 11 and maintains a relatively static positional relationship with the water outlet cavity 11. It is impossible to select the elasticity and size of the support portion 4, and the limitations are relatively large. When the support portion 4 is a sealing ring separately provided from the water outlet cavity 11, the sealing performance between the support portion 4 and the water outlet panel 2 is improved, and the size and elasticity of the support portion 4 can be flexibly selected, so that the water outlet panel 2 is in the best position and obtains good stability.

[0038] In some embodiments, the inner diameter of the support portion 4 is smaller than the maximum diameter of the water outlet panel 2, and when the water outlet panel 2 is coaxially arranged with the water outlet body 1 and completely covers the water outlet 12, the maximum diameter of the water outlet panel 2 is located on the side of the support portion 4 away from the water outlet 12. The limitation of the above conditions is mainly used to limit the water outlet panel 2 in the water outlet cavity 11 after the water outlet panel 2 is inserted into the water outlet cavity 11, so that the water outlet panel 2 can maintain a relatively stable positional relationship even when it is impacted by water flow.

[0039] In some embodiments, referring to Figure 9 , the water outlet panel 2 has a first water passing member 21 and a second water passing member 22. An inlet 23 communicating with both the first water passing member 21 and the second water passing member 22 is formed on the circumferential side wall of the water outlet panel 2. When the water outlet panel 2 is coaxially arranged with the water outlet body 1, the inlet 23 is located on the side of the support portion 4 away from the water outlet 12. When the water outlet panel 2 is coaxially arranged with the water outlet body 1, taking the first water passing member 21 as the water inlet surface as an example, a part of the water flow first passes through the water passing holes of the first water passing member 21 and then enters the inside of the water outlet panel 2. At the same time, another part of the water flow will flow into the inside of the water outlet panel 2 from the inlet 23. The two parts of the water flow converge inside the water outlet panel 2 and then flow out through the second water passing member 22. Since the water outlet panel 2 is rotatably connected to the water outlet body 1, both the first water passing member 21 and the second water passing member 22 can be used as the water inlet surface. Whether the first water passing member 21 or the second water passing member 22 is used as the water inlet surface, a part of the water flow will enter the water outlet panel 2 from the inlet 23 and converge with another part of the water flow and then flow out. Therefore, the setting of the inlet 23 is mainly used to increase the water flow rate finally output from the water passing member serving as the water outlet surface to the outside.

[0040] It can be understood that the first water passing member 21 and the second water passing member 22, as two different parts, can be provided with completely different water outlet structures or water outlet mesh surfaces. In this case, when the first water passing member 21 or the second water passing member 22 is used as the water outlet surface, different water flowers will be formed. Since different water outlet structures / water outlet mesh surfaces have different water passing areas, when the two are respectively used as the water inlet surface, the input flow rate obtained by the other water passing member serving as the water outlet surface will be different. For example Figure 7 andFigure 8 As shown, the first water-passing member 21 has a grid-shaped water outlet net, while the water outlet structure of the second water-passing member 22 is composed of densely arranged small water-passing holes. Obviously, the flow-through area of the first water-passing member 21 is much larger than that of the second water-passing member 22. Therefore, when the first water-passing member 21 is used as the water inlet surface, the flow rate entering the water outlet panel 2 from the first water-passing member 21 is larger, and when the second water-passing member 22 is used as the water inlet surface, the flow rate entering the water outlet panel 2 from the second water-passing member 22 is smaller. Therefore, when the second water-passing member 22 is used as the water inlet surface and the first water-passing member 21 is used as the water outlet surface (i.e., Figure 7 the form shown), the first water-passing member 21 cannot obtain sufficient input flow rate, resulting in difficulty in forming the finally output water flowers (the flow rate is not sufficient) and unable to meet the usage scenarios of the water flowers. In other possible designs, in order to design a certain water-passing member to output a strong water column with extremely high water pressure for single column or multi-column, it is even necessary to set no more than 10 water outlet holes. When this water-passing member is used as the water inlet surface, it is easy to anticipate to what extent the input flow rate obtained by the other water-passing member used as the water outlet surface will be small. In the above-mentioned situations, it is necessary to set the water inlet 23, which can bring supplementary flow rate and support the large flow rate output requirements of the water-passing member used as the water outlet surface.

[0041] In some embodiments, referring to Figure 9 and Figure 10 , an inlet channel 3 communicating with the water inlet 23 is formed between the inner wall of the water outlet panel 2 and the inner wall of the water outlet cavity 11. The formation of the inlet channel 3 is used to divide the water flow, so as to ensure that part of the water flow will flow into the water outlet panel 2 from the water inlet 23, and at the same time reduce the water pressure borne by the water inlet surface of the water inlet panel.

[0042] In some embodiments, the circumferential side wall of the water outlet panel 2 and the inner wall of the water outlet cavity 11 are spherical surfaces or polyhedral surfaces. Among them, the spherical surface includes a complete spherical surface and an incomplete spherical surface; when the circumferential side wall of the water outlet panel 2 is a complete spherical surface, in the axial sectional view of the water outlet panel 2, the circumferential side wall of the water outlet panel 2 is an arc and the distances between the points on the arc and the three-dimensional center point of the water outlet panel 2 are all equal; the incomplete spherical surface means that in the axial sectional view of the water outlet panel 2, the circumferential side wall profile of the water outlet panel 2 is a combination of an arc and a straight line, and the radii of the points on the arc and the three-dimensional center point of the water outlet panel 2 are not all equal; while the polyhedral surface means that in the axial sectional view of the water outlet panel 2, the circumferential side wall profile of the water outlet panel 2 is a combination of multiple straight lines. Correspondingly, the water outlet cavity 11 is one of a complete spherical surface, an incomplete spherical surface or a polyhedral surface, and it is the best choice that the water outlet cavity 11 is a complete spherical surface. To enable the water outlet panel 2 to rotate smoothly in the water outlet cavity 11, the circumferential side wall of the water outlet panel 2 is a complete spherical shape. Correspondingly, the water outlet cavity 11 is also a complete spherical shape, but the difference is that there is a difference in the inner wall dimensions between the water outlet panel 2 and the water outlet cavity 11. Specifically, in order to enable the water outlet panel 2 to withstand the impact of water flow and always be in contact with the support portion 4 when the water outlet panel 2 is embedded in the water outlet cavity 11, in some embodiments, when the axis of the water outlet panel 2 is perpendicular to the axis of the water outlet 12, the axis of the water outlet panel 2 is located on the side of the support portion 4 away from the water outlet 12, so that the maximum diameter of the water outlet panel 2 is always located on the side of the water outlet cavity 11 away from the water outlet 12.

[0043] In some embodiments, in the axial direction of the water outlet panel 2, at least one surface of the water outlet panel 2 is provided with a friction enhancement portion 5. Optionally, one or both surfaces in the axial direction of the water outlet panel 2 are provided with a friction enhancement portion 5. Specifically, the friction enhancement portion 5 can be a convex lip provided around the peripheral edge of the surface of the water outlet panel 2 or protrusions provided at intervals around the peripheral edge of the surface of the water outlet panel 2, or a water outlet net with a large friction force can be used on the surface of the water outlet panel 2.

[0044] Referring to Figures 1 - 5 , Embodiment 1 of the present invention is:

[0045] A water flow shaper includes a water outlet body 1 and a water outlet panel 2 rotatably connected to the water outlet body 1; the water outlet body 1 has a water outlet cavity 11, the water outlet cavity 11 has a water outlet 12, and the inner diameter of the water outlet 12 is smaller than the maximum diameter of the water outlet panel 2; two symmetrically arranged relief openings 13 are provided on the water outlet 12, so that the water outlet panel 2 can be embedded in or disengaged from the water outlet 12 through the relief openings 13.

[0046] In this embodiment, referring to Figure 4 , the relief opening 13 gradually depresses in the radial direction of the water outlet 12 along the direction opposite to the water outlet direction.

[0047] In this embodiment, referring to Figure 5 in the circumferential direction of the water outlet 12, the length W of the relief opening 13 is greater than the axial thickness w of the water outlet panel 2, and the difference is 0.4 mm. Wherein, the axial thickness w of the water outlet panel 2 refers to the distance between the end face of the first water passing member 21 and the end face of the second water passing member 22.

[0048] In this embodiment, the water outlet cavity 11 has a necking 14 near the relief opening 13. When the water outlet panel 2 is inserted into or disengaged from the water outlet 12 through the relief opening 13, the water outlet panel 2 is in transitional fit with the necking 14.

[0049] In this embodiment, in the axial direction of the water outlet body 1, the thickness g at the necking 14 is 0.55 mm, 0.6 mm or 0.65 mm.

[0050] In this embodiment, in this embodiment, the diameter k of the necking 14 is greater than the maximum diameter D of the water outlet panel 2, and the difference between the diameter k of the necking 14 and the maximum diameter d of the water outlet panel 2 is 0.4 mm. In other equivalent embodiments, the diameter k of the necking 14 may also be equal to the maximum diameter D of the water outlet panel 2, or less than the maximum diameter D of the water outlet panel 2. When the diameter k of the necking 14 is less than the maximum diameter D of the water outlet panel 2, the difference between the two is less than 0.1 mm. Wherein, the maximum diameter D of the water outlet panel 2 is 12 mm to 30 mm.

[0051] In this embodiment, the ratio of the axial thickness w of the water outlet panel 2 to the diameter d of the water outlet 12 is 0.344. When the axis of the water outlet panel 2 is perpendicular to the axis of the water outlet 12, the maximum distance t between the water outlet panel 2 and the water outlet 12 is 4 mm to 15 mm. The maximum distance t between the water outlet panel 2 and the water outlet 12 refers to, in the above state, referring to Figure 5 in the projection area in the axial direction of the water outlet 12, the maximum distance in the radial direction of the notch 15 formed between the water outlet panel 2 and the inner wall of the water outlet 12.

[0052] In this embodiment, referring to Figure 4 and Figure 9 the water outlet cavity 11 has a support portion 4 pressing against the water outlet panel 2 near the water outlet 12. The support portion 4 is a sealing ring separately provided from the water outlet cavity 11, and the inner diameter of the position where the support portion 4 contacts the water outlet panel 2 is less than the maximum diameter of the water outlet panel 2. And when the water outlet panel 2 is coaxially arranged with the water outlet body 1 and completely covers the water outlet 12, the maximum diameter of the water outlet panel 2 is located on the side of the support portion 4 away from the water outlet 12.

[0053] In this embodiment, referring to Figure 4 the circumferential side wall of the water outlet panel 2 and the inner wall of the water outlet cavity 11 are both complete spherical surfaces.

[0054] In this embodiment, refer to Figure 4 In the axial direction of the water outlet panel 2, both sides of the water outlet panel 2 are provided with a friction enhancement part 5. Specifically, the friction enhancement part 5 is an annular convex lip, and the circumferential thickness of the friction enhancement part 5 on both sides of the water outlet panel 2 can be the same or different. In this embodiment, the two friction enhancement parts 5 of the water outlet panel 2 have different thicknesses. The axial thickness of the friction enhancement part 5 is 0.1 mm to 1 mm. Preferably, the axial thickness of the friction enhancement part 5 is 0.3 mm, 0.4 mm, 0.5 mm or 0.6 mm.

[0055] In this embodiment, refer to Figure 2 In order to reduce the difficulty of turning over the water outlet panel 2, a turning rod 6 is respectively provided in the end surfaces on both sides of the axial direction of the water outlet panel 2, and the axial length of the turning rod 6 is not greater than the maximum radius of the water outlet panel 2. When the water outlet panel 2 is squeezed by external force or impacted by water flow, the water outlet panel 2 will contact the inner wall of the water outlet cavity 11, so that the water outlet panel 2 is always located in the water outlet cavity 11.

[0056] The working principle of this embodiment is:

[0057] When the water outlet device is in working state, the water outlet panel 2 and the water outlet body 1 are basically in a coaxial state; the axis of the water outlet panel 2 and the water outlet body 1 can also maintain a certain angle (for example, the angle formed by the axes of the two is within 15 degrees), so that the water flow output by the water outlet panel 2 will have a certain angle relative to the water inlet direction, and the angle is consistent with the angle of the axes of the two;

[0058] Reference Figure 2 and Figure 5 When the water outlet panel 2 needs to be disassembled for cleaning, the water outlet panel 2 is turned over so that the axis of the water outlet panel 2 is perpendicular or nearly perpendicular to the axis of the water outlet 12, and the water outlet panel 2 is rotated along the circumference of the water outlet so that the water outlet panel 2 is completely aligned with the two clearance openings 13 in the radial direction, and the two water-passing end surfaces of the water outlet panel 2 are pinched by hand and pulled out in the water outlet direction of the water outlet device. In this process, the support portion 4 will be slightly concave due to being squeezed by the maximum diameter of the water outlet panel 2;

[0059] The disassembled water outlet panel 2 can be cleaned by physical cleaning or chemical cleaning to remove scale and other impurities. The physical cleaning mainly involves brushing the mesh of the water outlet panel 2 with a cleaning tool to remove soft scale on the water outlet hole of the water outlet panel 2 and other impurities that clog the mesh. The chemical cleaning can be performed by soaking the water outlet panel 2 with an acidic detergent to remove hard scale on the water outlet hole of the water outlet panel 2 or on the water path inside the water outlet panel 2.

[0060] After cleaning, make the axis of the water outlet panel 2 perpendicular to the axis of the water outlet 12, and make the water outlet panel 2 exactly aligned with the two relief openings 13 in the radial direction. Then, press the water outlet panel 2 into the water outlet cavity 11 from the water outlet 12 and maintain the fit with the water outlet cavity 11 to complete the assembly. Then, turn either side of the water outlet panel 2 (selected according to the water spray to be output) to cover the entire water outlet 12, and the water outlet device can be used normally.

[0061] Embodiment 2 of the present invention is as follows:

[0062] A water flow shaper. The difference between this embodiment and Embodiment 1 is that only one relief opening 13 is provided.

[0063] In this embodiment, in order to ensure that the water outlet panel 2 can be smoothly pulled out or inserted into the water outlet 12, the minimum distance from the relief opening 13 to the axis of the water outlet 12 is greater than the radius of the water outlet 12, and the difference is 0.05 mm, to avoid deformation of the water outlet 12 and reduce the difficulty of pulling out or inserting the water outlet panel 2. In other equivalent embodiments, the minimum distance from the relief opening 13 to the axis of the water outlet 12 can also be less than the radius of the water outlet 12, and the difference is less than 0.1 mm.

[0064] Refer to Figures 7 - 10 , Embodiment 3 of the present invention is as follows:

[0065] A water flow shaper. On the basis of Embodiment 1 or Embodiment 2, this embodiment provides a water outlet panel 2 with a different structure.

[0066] In this embodiment, the water outlet panel 2 has a first water passage member 21 and a second water passage member 22, and the first water passage member 21 and the second water passage member 22 have different water outlet structures / water outlet meshes to form different water sprays. An inlet 23 communicating with both the first water passage member 21 and the second water passage member 22 is provided on the circumferential side wall of the water outlet panel 2. When the water outlet panel 2 is coaxially arranged with the water outlet body 1, the inlet 23 is located on the side of the support portion 4 away from the water outlet 12. When the water outlet panel 2 is coaxially arranged with the water outlet body 1, taking the first water passage member 21 as the water inlet surface as an example, a part of the water flow first enters the interior of the water outlet panel 2 through the first water passage member 21, and at the same time, another part will flow into the interior of the water outlet panel 2 from the inlet 23. The two parts of the water flow converge inside the water outlet panel 2 and then flow out through the second water passage member 22. It is easy to understand that since the water outlet panel 2 is rotatably connected to the water outlet body 1, both the first water passage member 21 and the second water passage member 22 can be used as the water inlet surface. Whether the first water passage member 21 or the second water passage member 22 is used as the water inlet surface, a part of the water flow will enter the water outlet panel 2 from the inlet 23 as a supplement to the flow rate and converge with another part of the water flow and then flow out from the water outlet surface.

[0067] In this embodiment, an intake channel 3 communicating with the water inlet 23 is formed between the water outlet panel 2 and the inner wall of the water outlet cavity 11. By correspondingly designing the sizes of the water inlet 23 and the intake channel 3, different flow rates of replenishment can be achieved.

[0068] The working principle of this embodiment is as follows:

[0069] Referring to Figure 10 , when the first water passage member 21 serves as the water inlet surface, the water flow can pass through the first water passage member 21 and then sequentially through the intake channel 3 and the water inlet 23, enter the water outlet panel 2, and finally be output as formed water flowers through the second water passage member 22.

[0070] Conversely, the water outlet panel 2 can be flipped so that the second water passage member 22 serves as the water inlet surface. When the first water passage member 21 or the second water passage member 22 serves as the water inlet surface, the water flowers flowing through the water outlet panel 2 have different forms.

[0071] In summary, for a water flow shaper provided by the present invention, to ensure that the water outlet panel can always remain in the water outlet cavity after being impacted by the water flow, the diameter of the water outlet is set to be smaller than the maximum diameter of the water outlet panel, so that the water outlet panel is always clamped in the water outlet cavity under normal working conditions. By providing a relief opening on the water outlet, the water outlet panel can be pulled out or inserted into the water outlet cavity after rotating to a position facing the relief opening, which not only ensures the stability of the water outlet panel in the water outlet cavity but also enables the water outlet panel to be quickly assembled and disassembled, making the disassembly and assembly of the water outlet panel and the water outlet cavity not limited by the material rigidity of the water outlet cavity or the water outlet panel, and having a wider application range.

[0072] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. All equivalent transformations made using the content of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are equally included in the patent protection scope of the present invention.
