Although the present disclosure provides examples of various specific processes and materials, those skilled in the art may recognize the application of other processes and / or the use of other materials.
[0017] As shown in FIGS. 1 to 11, an embodiment of the present disclosure provides a water discharge device 100, which may include a jet disc 1 and a cover body 2 attached together with the jet disc 1 to form a water flow passage.
[0018] As shown in Figures 1 and 2, the jet disc 1 may include a disc body 10, which may have a first disc surface (the top surface of the disc body 10 shown in the figure) and a second disc surface (the bottom surface of the disc body 10 shown in the figure) that face each other. The jet disc 1 may further include a nozzle portion 11 that is provided on the disc body 10 and protrudes from the second disc surface. The nozzle portion 11 may include a side wall 111 and a bottom wall 112 that surround the nozzle portion 11 to form a hollow cavity A, and a water outlet hole 1120 may be provided in the bottom wall 112 of the nozzle portion 11.
[0019] In the embodiments of the present disclosure, the nozzle portion 11 and the disk body 10 may be assembled separately. In one exemplary embodiment, the nozzle portion 11 and the disk body 10 may be integrally molded, for example, by integral casting, where the disk body 10 is first molded, and then the nozzle portion 11 and the disk body 10 are cast integrally.
[0020] In the embodiment of the present disclosure, the disk body 10 may be a circular plate-like body, and its main function is to support the nozzle portion 11. Alternatively, the disk body 10 may have other shapes such as a rectangular shape, a cylindrical shape, etc. The specific shape and size of the disk body 10 are not limited herein.
[0021] In the embodiment of the present disclosure, the hollow cavity A of the nozzle portion 11 may be tank-shaped, into which a water flow enters and from which the water flow is ejected to the outside. Alternatively, the nozzle portion 11 may have other shapes such as a rectangular parallelepiped or a tapered shape, and is not limited thereto.
[0022] As shown in Figures 1 and 2, the lid body 2 may include a lid plate 20, which may have opposing first and second disk surfaces (the top and bottom surfaces of the lid plate 20 shown in the figure), and the lid body 10 may further include an extension portion 21 extending from the second plate surface toward the first disk surface of the disk body 10 and extending into the hollow cavity A of the nozzle portion 11.
[0023] The cover plate 20 in the embodiments of the present disclosure may be a circular plate, or the overall shape of the cover plate 20 may be adapted to the shape of the disk body 10, with its main function being to accommodate the extension portion 21. Alternatively, the cover plate 20 may have a shape similar to a bottle cap or other shapes. The cross-sectional size of the cover plate 20 may be the same as, or larger or smaller than, the cross-sectional size of the disk body 10. The specific shape and size of the cover plate 20 can be determined according to actual circumstances and are not limited herein.
[0024] As shown in Figure 3, when the jet disc 1 is assembled with the cover body 2, the second disc surface of the disc body 10 can face the first disc surface of the cover plate 20, the extension part 21 of the cover plate 20 can protrude into the hollow cavity A of the nozzle part 11, and the gap between the outer wall surface of the extension part 21 and the inner wall surface of the side wall 111 of the nozzle part 11 can form the fountain flow path 3. The water outlet end of the fountain flow path 3 communicates with the water outlet hole 1120 in the bottom wall 112 of the nozzle part 11, allowing the water flow to be sprayed to the outside (the flow direction of the water flow is shown by the dashed arrow in Figure 3).
[0025] In the embodiment of the present disclosure, the water outlet 1120 may include a plurality of holes, and the water flow enters the fountain channel 3 and then sprays out from the plurality of holes 1120 to form a water flow like drizzle.
[0026] In this embodiment, an extension 21 is provided on the cover 2 of the water discharge device 100, and the gap between the outer wall surface of the extension 21 and the inner wall surface of the side wall 111 of the nozzle part 11 forms a fountain flow path 3, which allows the water pressure to be concentrated on the side wall 111 of the nozzle part 11, stabilizing the dimensions of the nozzle part 11 and preventing the hollow cavity A of the nozzle part 11 from expanding and deforming due to the influence of water pressure, thereby making the water shape of the water discharge unstable. At the same time, maintaining the dimensions of the nozzle part 11 stable prevents deformation and damage to the nozzle part 11, and also extends the life of the nozzle part 11.
[0027] 1 and 2, the nozzle portion 11 may further include an annular stopper portion 110A and a nozzle pipe portion 110B extending from the annular stopper portion 110A toward the second disc surface of the disc body 10, and the nozzle pipe portion 110B may protrude beyond the second disc surface of the disc body 10 (see FIG. 3). The portion of the nozzle pipe portion 110B protruding beyond the second disc surface of the disc body 10 allows the user to rub and clean the nozzle portion 11 to achieve the purpose of removing scale.
[0028] In one exemplary embodiment, the ratio of the length of the nozzle portion 11 provided within the disk body 10 to the length of the nozzle portion 11 protruding from the disk body 10 may be in the range of 0.13 to 7, thereby preventing the nozzle portion 11 from expanding and achieving a stable water discharge effect.
[0029] 2, the disk body 10 may further include a sunken groove 101A recessed inward from the first disk surface of the disk body 10 and a through-hole 101B connecting the sunken groove 101A to the second disk surface of the disk body 10. The annular stopper portion 110 of the nozzle portion 11 can be attached within the sunken groove 101A of the disk body 10 and can fit into the sunken groove 101A to restrict its position, preventing the nozzle portion 11 from coming out of the jet disk 1 due to the impact of the water flow and preventing the nozzle portion 11 from swinging in the radial direction of the jet disk 1. The nozzle pipe portion 110B can protrude from the second disk surface through the through-hole 101B.
[0030] 3, the nozzle pipe portion 110B of the nozzle portion 11 may be attached to the through-hole 101B via a gap. There may be a gap between the inner wall surface 1011 of the through-hole 101B and the outer wall surface of the nozzle pipe portion 110B of the nozzle portion 11. On the one hand, this gap facilitates the assembly of the nozzle portion 11 and the jet disc 1, and on the other hand, it provides the nozzle portion 11 with a certain amount of space for expansion and deformation when the water flow enters the nozzle portion 11, thereby preventing the water flow from becoming unstable due to excessive expansion of the portion of the nozzle portion 11 protruding from the jet disc 1.
[0031] In the embodiments of the present disclosure, the material hardness of the nozzle portion 11 may be designed to be less than the material hardness of the disk body 10. The nozzle portion 11 may be made of a soft material with a low hardness, which makes it easier for the user to rub and clean the nozzle portion 11 to remove scale. The nozzle portion 11 may generally be made of an elastic material such as rubber or silicone rubber, and the disk body 10 and the cover body 20 may generally be made of a rigid material such as hard plastic.
[0032] 1 and 4, the outer wall surface of the extension portion 21 may be provided with a plurality of grooves 210 spaced apart in the circumferential direction, and the grooves 210 may extend along the axial direction of the extension portion 21. The plurality of grooves 210 can form a plurality of fountain flow paths 3 together with the inner wall surface of the side wall 111 of the nozzle portion 11, thereby preventing the nozzle portion 11 from expanding due to excessive flow rate and pressure of the water flow entering the nozzle portion 11, causing the dimensions of the nozzle portion 11 to become unstable.
[0033] As shown in Figures 3 and 5, the bottom wall 112 of the nozzle portion 11 may be provided with a convex extension 113 that extends into the hollow cavity A of the nozzle portion 11, and the water outlet hole 1120 may be arranged on the outer periphery of the convex extension 113 (see Figure 6). The extension 21 of the cover plate 2 and the convex extension 113 of the nozzle portion 11 may be provided with a fitting structure that fits into each other. The fitting structure between the extension 21 and the convex extension 113 allows, on the one hand, to accurately position the extension 21 when the jet disc 1 is assembled with the cover body 2, maintaining uniformity and stability of water outlet, and on the other hand, allows the extension 21 to be rocked when the nozzle portion 11 is descaled and cleaned, improving the descaling effect and allowing the extension 21 to return to its initial position after descaling and cleaning.
[0034] As shown in FIG. 3, the mating structure may include a tapered protrusion 1130 provided on one of the protruding portion 113 and the extending portion 11, and a tapered groove 210 provided on the other, and the tapered protrusion 1130 can extend into the tapered groove 210 and be fitted into the tapered groove 210.
[0035] The water discharge device 100 of the embodiment of the present disclosure has a convex extension portion 113 within the nozzle portion 11, which increases the strength of the bottom wall 112 of the nozzle portion 11 and prevents deformation of the bottom wall 112 of the nozzle portion 11 by concentrating water pressure on the side wall of the nozzle portion 11.
[0036] In one exemplary embodiment, the ratio of the cross-sectional area of the flow of the water flow passage 3 of the nozzle portion 11 to the cross-sectional area of the flow of the water outlet hole 1120 may be in the range of 0.15 to 2, which can maintain better water outlet pressure and flow rate, avoid expansion, and maintain a stable water outlet shape.
[0037] The cross-sectional area of the water fountain channel 3 of the water discharger 100 according to the embodiment of the present disclosure may be larger than the cross-sectional area of the water outlet 1120, so that the water flow has a certain jetting flow rate.
[0038] As shown in Figures 3 and 6, one end of hollow cavity A close to the outlet hole 1120 may be formed in a contracted shape to form a communication section between the fountain flow path 3 and the outlet hole 1120. By forming one end of hollow cavity A close to the outlet hole 1120 in a contracted shape, the flow rate of the water flow can be increased, thereby producing a spraying effect.
[0039] In one exemplary embodiment, as shown in FIG. 9, one end of the hollow cavity A close to the outlet hole 1120 may not be contracted, and the outlet end of the water fountain channel 3 may correspond one-to-one with the outlet hole 1120 in the water outlet direction, and the water flow may directly enter the outlet hole 1120 and be sprayed out without accelerating or increasing.
[0040] 2, a plurality of protrusions 102 may be provided at intervals on the disk surface (first disk surface) of the disk body 10 facing the cover body 2. The plurality of protrusions 102 can divide the cavity between the disk body 10 and the cover plate 20 into a plurality of passages, thereby forming a water supply flow path B. The water supply flow path B may extend along the radial direction of the disk body 10.
[0041] In one exemplary embodiment, the protrusions 102 may be provided on the disk surface of the cover 2 facing the disk 10. When the water flow enters the water discharge device 100, the water flow can flow from the multiple circumferentially spaced water supply channels B into the jetting channel 3 and then be jetted out from the water outlet holes 1120.
[0042] 7A to 7D, the shape of the water outlet holes 1120 of the nozzle portion 11 may include a variety of shapes, such as a circle, a square, a triangle, etc. The number of water outlet holes 1120 may be a variety of shapes, such as two, three, four, six, etc., and can be determined specifically according to the actual situation. By designing the shape, size, and number of the water outlet holes 1120 of the nozzle portion 11, it is possible to realize water flows of different shapes and water column numbers like thread rain.
[0043] As shown in FIG. 11, the direction in which the water outlet holes 1120 of the nozzle portion 11 of the embodiment of the present disclosure extend may be parallel to the axial direction of the nozzle portion 11, so that the nozzle portion 11 can spray vertical water sprays.
[0044] In one exemplary embodiment, as shown in Figure 10, the extension direction of the water outlet holes 1120 of the nozzle unit 11 may form an angle with the axial direction of the nozzle unit 11, allowing the nozzle unit 11 to spray inclined water droplets. This angle is approximately 0 to 30 degrees and may be designed according to the desired shape of the water droplets. When the water discharge device 100 is applied to a shower head, the inclined water droplets sprayed from the multiple nozzle units 11 arranged on the end face of the shower head can form multiple three-dimensional water droplets, such as a staggered pattern of small, rounded droplets.
[0045] In the nozzle portion 11 according to the embodiment of the present disclosure, various stable water shapes can be obtained by designing the shape of the water outlet hole 1120.
[0046] In the embodiments of the present disclosure, the multiple water outlet holes 1120 may be arranged in one-to-one correspondence with the multiple fountain flow paths 3 (the multiple water outlet holes 1120 may be connected to the multiple fountain flow paths 3 in one-to-one correspondence), and the supply water may be drawn out in a one-to-one correspondence, thereby preventing deformation of the nozzle portion 11 due to closing pressure and concentrating water pressure on the side walls of the nozzle portion 11 to prevent deformation of the center of the nozzle portion 11.
[0047] In one exemplary embodiment, the plurality of water outlet holes 1120 do not have to be provided in one-to-one correspondence with the plurality of fountain channels 3. For example, when the water flow rate is high, the water outlet holes 1120 do not have to be provided in one-to-one correspondence with the plurality of fountain channels 3. Illustratively, the water outlet holes 1120 and the plurality of fountain channels 3 may be arranged to intersect along the radial direction of the bottom wall 112.
[0048] As shown in Figures 8A to 8D, multiple grooves 210 may be provided on the side wall of the extension portion 21, and the multiple grooves 210 may be of multiple types, such as two to eight in number, and may have multiple types of shapes, such as square or arc-shaped, and can be set specifically according to the actual situation, but are not limited here.
[0049] 8E to 8F, the plurality of grooves 210 may be provided on the inner wall surface of the nozzle portion 11, and may be combined with the outer wall surface of the extension portion 21 to form the ejection flow path 3. The number of the plurality of grooves 210 can be set according to the actual situation, and is not limited here.
[0050] 12 and 13, an embodiment of the present disclosure further provides a faucet 200, which may include a faucet body 201 and a water discharge device 100 described in any of the above embodiments (see the portion of the water discharge device 100 enclosed in a dashed line in FIG. 13) attached to the outlet end of the faucet body 201. The water discharge device 100 may be provided at the outlet end of the faucet body 201, such that the water discharge device 100 is entirely provided at the outlet end of the faucet 100, and the water supply channel of the water discharge device 100 may communicate with the water supply channel of the faucet body 201.
[0051] The water discharge device 100 in the embodiment of the present disclosure may include a plurality of water discharge devices 100, and the cover plates 20 of the plurality of water discharge devices 100 may be designed as an integrated unit, and a plurality of extension portions 21 may be disposed on the cover plate 20. The disk bodies 10 of the plurality of water discharge devices 100 may be designed as an integrated unit, and the disk body 10 may be provided with a plurality of nozzle portions 11 equal to the number of extension portions 21. The integrated design of the cover plate 20 and the disk body 10 allows for easy assembly.
[0052] In one exemplary embodiment, the cover plates 20 of the plurality of water dispensers 100 may be of separate design, and the disk bodies 10 of the plurality of water dispensers 100 may be of separate design.
[0053] As shown in FIGS. 14 and 15 , an embodiment of the present disclosure further provides a shower head 300, which may include a shower head body 301 and a water discharge device 100 described in any of the above embodiments attached to the shower head body 301. The water discharge device 100 may be disposed at the water outlet end of the shower head body 301, such that the water discharge device 100 is entirely disposed at the water outlet end of the shower head 300, and the water supply channel of the water discharge device 100 may be connected to the water supply channel of the shower head body 301.
[0054] The water discharge device 100 in the embodiment of the present disclosure may include a plurality of water discharge devices 100, and the cover plates 20 of the plurality of water discharge devices 100 may be designed as an integrated unit, and a plurality of extension portions 21 may be disposed on the cover plate 20. The disk bodies 10 of the plurality of water discharge devices 100 may be designed as an integrated unit, and the disk body 10 may be provided with a plurality of nozzle portions 11 equal to the number of extension portions 21. Similarly, the integrated design of the cover plate 20 and the disk body 10 allows for easy assembly.
[0055] In one exemplary embodiment, the cover plates 20 of the plurality of water dispensers 100 may be of separate design, and the disk bodies 10 of the plurality of water dispensers 100 may be of separate design.
[0056] The water discharge device 100 of the embodiment of the present disclosure may draw in water in a one-to-one ratio, and the disk body 10 may be made of hard plastic, which will not deform under water pressure and can concentrate water pressure on the side walls of the nozzle part 11 without deforming the center of the nozzle part 11. When water pressure is high, the through-hole 101B of the hard plastic disk body 10 forms a restricted flow with the part located within the through-hole 101B of the rubber nozzle part 11, thereby preventing the inflowing water pressure from becoming excessive, ensuring the dimensional stability of the bottom wall of the rubber nozzle part 11 and good water discharge effect.
[0057] A tapered protrusion 1130 may be provided within the hollow cavity A of the nozzle portion 11 in the embodiment of the present disclosure, and the tapered protrusion 1130 can be fitted into the tapered groove 210 of the extension column 21 of the cover body 2, thereby increasing strength while facilitating assembly and improving assembly efficiency and dimensional stability.
