Description

Water outlet structure and water outlet device Technical Field

[0001] The present invention relates to a water outlet device, in particular to a water outlet structure and a water outlet device. Background Art

[0002] In bathroom products, to ensure that the final discharged water flow meets the water requirements of the pre-set form and usage scenario, and in particular, to comply with the flow discharge standards set by different countries and regions for bathroom products, bathroom products often require a flow control device upstream of the water outlet. For example, by installing a flow controller (also known as a flow regulator, water-saving tablet, water-saving tablet, or flow-limiting tablet) in a faucet or showerhead, it can be used to limit the flow rate or even maintain a constant flow rate. For example, the solutions disclosed in patents such as CN201973314U, CN203176476U, CN1759268A, and CN102788178A all fall into the category of flow controllers.

[0003] Some existing water outlet devices have a reversible water outlet structure, such as the solutions disclosed in patents such as CN140104169A and CN219280829U. However, since the discharge water flows from different water outlet surfaces have different flow requirements for the upstream input water flow, the existing flow control devices cannot meet the flow control requirements of the reversible water outlet structure. For example, the solution of CN140104169A also needs to adjust the position of the water outlet surface to achieve input flow control for different water outlet surfaces, and the structure is relatively complicated. Technical issues

[0004] The technical problem to be solved by the present invention is to provide a water outlet structure and a water outlet device to overcome the defect that the reversible water outlet structure in the prior art cannot control the flow rate. Technical Solutions

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A water outlet structure includes a first water pass plate, a second water pass plate and an elastic member;

[0007] The first water-passing plate has at least one first through hole;

[0008] The second water-passing plate has at least one second through hole;

[0009] A water flow cavity is formed between the first water flow plate and the second water flow plate, and the elastic member is disposed in the water flow cavity;

[0010] When the elastic member is deformed or the relative position of the elastic member and at least part of the first through hole and / or the second through hole changes, the total water flow area of ​​the first through hole and / or the total water flow area of ​​the second through hole changes.

[0011] In order to solve the above technical problems, the second technical solution adopted by the present invention is:

[0012] A water outlet device, comprising a water outlet body and the water outlet structure as described above;

[0013] The water outlet structure is connected to the water outlet end of the water outlet body in a relatively rotatable manner.

[0014] In order to solve the above technical problems, the third technical solution adopted by the present invention is:

[0015] A water outlet device, comprising a water inlet and the water outlet structure as described above;

[0016] The water outlet structure is detachably connected to the water inlet end of the water inlet body. Beneficial effects

[0017] The beneficial effect of the present invention is that the elastic member changes its position or deforms within the water outlet structure during inversion or when subjected to changing water flow, thereby changing the total water flow area of ​​the first and second through-holes, thereby achieving flow control. Therefore, the water outlet structure and device of the present invention can not only change the water outlet surface to form different water splashes, but also achieve flow regulation.

[0035] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0036] Referring to Figures 1-14, a water outlet device includes a water outlet body and a water outlet structure 100. The water outlet structure 100 is rotatably connected to the outlet end of the water outlet body and is rotatable about an axis perpendicular to the direction of water flow and passing through the axis of the water outlet structure 100. Specifically, the water outlet structure 100 includes a first water pass plate 110, a second water pass plate 120, and an elastic member 130. The first water pass plate 110 has at least one first through hole 111; the second water pass plate 120 has at least one second through hole 121. A water flow cavity is formed between the first water pass plate 110 and the second water pass plate 120, and the elastic member 130 is disposed within the water flow cavity. When the elastic member 130 deforms or the relative position of the elastic member 130 and at least a portion of the first through hole 111 and / or the second through hole 121 changes, the total water flow area of ​​the first through hole 111 and / or the total water flow area of ​​the second through hole 121 changes.

[0037] All water inlets on the first water plate 110 are located within the corresponding first through-holes 111, and all water inlets on the second water plate 120 are located within the corresponding second through-holes 121. During the flipping process, the first water plate 110 will serve as either the water inlet or the water outlet. When the first water plate 110 is on the water inlet side, the second water plate 120 will serve as the water outlet side. When the first water plate 110 is on the water outlet side, the second water plate 120 will serve as the water inlet side.

[0038] Another water outlet device of the present invention includes a water outlet body and a water outlet structure 100; the water outlet structure 100 is detachably connected to the water inlet end of the water inlet body, and the water outlet structure 100 is threadedly connected, snap-fitted or interference-fitted to the water inlet end of the water inlet body.

[0039] It is understood that when the elastic member 130 is turned over or is affected by the changing water flow, it will change its position in the water outlet structure 100 or deform (the deformation of the elastic member 130 includes the deformation caused by the external force and the reset after the external force is removed), thereby changing the total water flow area of ​​the first through hole 111 and the second through hole 121. That is, the water flow area of ​​the first through hole 111 or the second through hole 121 will change, or the water flow area of ​​the first through hole 111 and the second through hole 121 will change, thereby achieving flow control. Therefore, the water outlet structure 100 and the water outlet device of the present invention can not only change the water outlet surface to form different water splashes, but also achieve flow regulation.

[0040] In some embodiments, the outer surface of the water outlet structure 100 has a partially spherical surface, which can be matched with a water outlet body having a ball socket. It can also be provided with threads on its outer surface for direct connection to the water outlet of a faucet. It can also be installed at the water inlet of a shower or the water outlet of a shower to act as a flow controller, by switching the water outlet and water inlet sides, so as to change the water flow state of the shower or shower. Alternatively, the outer wall of the water outlet structure is straight or arc-shaped.

[0041] In some embodiments, the elastic member 130 can separate from or press against the sidewall of the first through hole 111. When the elastic member 130 is deformed, the elastic member 130 can separate from or press against the sidewall of the first through hole 111, thereby changing the water flow area of ​​the first through hole 111 and thereby changing the total water flow area of ​​the first through hole 111 and the second through hole 121.

[0042] In some embodiments, the elastic member 130 can change its position in the axial direction of the water outlet structure 100. Specifically, the elastic member 130 has a first position and a second position in the axial direction of the water outlet structure 100. The switching between the first position and the second position is generated by flipping the water outlet structure 100.

[0043] In some embodiments, at least two first through holes 111 or at least two second through holes 121 can have their water flow areas changed simultaneously by one of the elastic members 130 to maintain a constant water flow during water discharge while ensuring the effectiveness of the change in water flow area, thereby ensuring flow regulation and water spray shaping effects. When the water flow area of ​​one of the first through holes 111 and the second through holes 121 is changed, the total water flow area of ​​the first through holes 111 and the second through holes 121 will change.

[0044] In some embodiments, when the elastic member 130 presses against the opening of the first through hole 111 and / or the second through hole 121 facing the water passage cavity, the elastic member 130 is in the first position, the water flow area of ​​the first through hole 111 and / or the second through hole 121 is minimized, and the elastic member 130 presses against the inner wall of the first through hole 111. Optionally, the inner wall of the first through hole 111 and / or the second through hole 121 can be smooth or have a through groove. When the inner wall of the first through hole 111 and / or the second through hole 121 is smooth, the pressurization of the elastic member 130 against the inner wall of the first through hole 111 and / or the second through hole 121 can reduce the water flow area of ​​the first through hole 111 and / or the second through hole 121 to zero. When the surface of the first through hole 111 and / or the second through hole 121 has a through groove, a small amount of water will flow through the gap between the elastic member 130 and the through groove, and the water flow area is small.

[0045] In some embodiments, when the elastic member 130 is deformed or moves toward the second water pass plate 120, the elastic member 130 presses against the second water pass plate 120. When the elastic member 130 moves toward the second water pass plate 120, the elastic member 130 can move to the second position and block the at least one second through-hole 121. Conversely, when the elastic member 130 is originally positioned closer to the second water pass plate 120, the elastic member 130 is deformed or moves toward the first water pass plate 110, the elastic member 130 presses against the first water pass plate 110. When the elastic member 130 moves toward the first water pass plate 110, the elastic member 130 can move to the second position and block the at least one first through-hole 111.

[0046] In some embodiments, an insert 140 is disposed between the first water pass plate 110 and the second water pass plate 120. When the elastic member 130 deforms or moves toward the first water pass plate 110 or the second water pass plate 120, the elastic member 130 presses against the insert 140. The support provided by the insert 140 maintains a water flow clearance between the elastic member 130 and both the first and second water pass plates 110 and 120, thereby maximizing the water flow area. Conversely, when the elastic member 130 is originally positioned closer to the second water pass plate 120, the elastic member 130 deforms or moves toward the first water pass plate 110, causing the elastic member 130 to press against the insert 140. The insert 140 can be a boss, a flow straightening mesh, or a flow straightening grid.

[0047] In some embodiments, the water outlet structure 100 has a first water outlet 112 and a second water outlet 122 that can communicate with the first water outlet 112 on either side of the axial direction. Specifically, the first water outlet 112 is located on the first water outlet plate 110, and the second water outlet 122 is located on the second water outlet plate 120. The first water outlet 112 is located on one of the first through-holes 111, and the second water outlet 122 is located on one of the second through-holes 121. In the radial direction of the water outlet structure 100, the cross-sections of the first water outlet 112 and the second water outlet 122 are different, so that water flows out of the different water outlets to achieve different water discharge conditions. In addition, the first water outlet plate 110 also has a third water outlet 113 that can communicate with the second water outlet 122. Similarly, the third water outlet 113 is located on the other first through-holes 111.

[0048] In some embodiments, the elastic member 130 is annular, and either end of the axial cross-section of the elastic member 130 is circular, U-shaped, or Y-shaped. When the elastic member 130 has different structures, its deformation amount and the changed position are different. Specifically, when either end of the axial cross-section of the elastic member 130 is U-shaped or Y-shaped, the deformation amount of the elastic member 130 when deformed is the largest, and the deformation of the elastic member 130 is sufficient to change its water flow area, so its position change in the water outlet structure 100 is the smallest; and when either end of the axial cross-section of the elastic member 130 is circular, the deformation amount of the elastic member 130 when deformed is the smallest, and in order to ensure the change of the water flow area, it is achieved by changing its position, so the position change in the water outlet structure 100 is the largest.

[0049] 1 and 2 , the first embodiment of the present invention is as follows:

[0050] The water outlet structure 100 includes a first water pass plate 110, a second water pass plate 120 and an elastic member 130; the water outlet structure 100 has a first through hole 111 and a second through hole 121; the elastic member 130 is arranged in the first through hole 111; when the elastic member 130 is deformed, the water pass area of ​​the first through hole 111 changes, so that the total water pass area of ​​the first through hole 111 and the second through hole 121 changes.

[0051] In this embodiment, a water passage cavity is formed between the first and second water passage plates 110, 120. An insert 140, a boss, is also disposed between the first and second water passage plates 110, 120. A water filter 150 is also provided on the second water passage plate 120. A first water passage 112 and a second water passage 122, which communicate with the first water passage 112, are located on either side of the water outlet structure 100 in the axial direction. Specifically, the first water passage 112 is located on the first water passage plate 110, while the second water passage 122 is located on the second water passage plate 120. Furthermore, the first water passage plate 110 has a third water passage 113, which communicates with the second water passage 122.

[0052] In this embodiment, the first water outlet 112 and the third water outlet 113 are respectively located on the corresponding first through hole 111 , and the second water outlet 122 is located on the second through hole 121 .

[0053] In this embodiment, either end of the axial cross-section of the elastic member 130 is Y-shaped. Specifically, when the first water pass plate 110 serves as the water outlet, the elastic member 130 is in the first position. At this point, the elastic member 130 presses against the inner wall of the first through hole 111 to block the third water outlet 113. Water flows in through the second water outlet 122 of the second water pass plate 120 and out through the first water outlet 112 (i.e., out of the first through hole 111). This achieves high-pressure water discharge over a small area. When the water outlet structure 100 flips 180°, the first water pass plate 110 serves as the water inlet. Under the impact of the water flow, the elastic member 130 presses against the insert 140, placing the elastic member 130 in the second position. Furthermore, the elastic member 130 deforms radially of the water outlet structure 100, connecting the second through-hole 121 with the first through-hole 111. Water enters through the first and third water passes 112 and 113, and exits through the second water pass 122, achieving a wide-area water outlet. During the flipping process of the water outlet structure 100, the deformation and slight positional shift of the elastic member 130 cause the water flow area of ​​the first through-hole 111 to change, increasing the total water flow area of ​​the first and second through-holes 111 and 121. Furthermore, because the cross-sectional area of ​​the first water pass 112 is larger than that of the second water pass 122, the water pressure and the shape of the water splashes during the outlet also change.

[0054] Please refer to Figures 3 and 4 for the second embodiment of the present invention:

[0055] The difference between this embodiment and the first embodiment lies in the difference in the structure of the elastic member 130 , the structure of the first water overflow plate 110 , and the structure of the second water overflow plate 120 .

[0056] In this embodiment, the water outlet structure 100 includes a first water pass plate 110, a second water pass plate 120 and an elastic member 130; the first water pass plate 110 has at least one first through hole 111; the second water pass plate 120 has at least one second through hole 121; the elastic member 130 is arranged in the first through hole 111; when the position of the elastic member 130 in the first through hole 111 changes, the total water flow area of ​​the first through hole 111 and the second through hole 121 changes.

[0057] In this embodiment, a water flow cavity is formed between the first water flow plate 110 and the second water flow plate 120. The insert 140 is a rectifier mesh that filters impurities in the water and supports the elastic member 130. Axially, the water outlet structure 100 has a first water flow port 112 and a second water flow port 122 that communicates with the first water flow port 112. Specifically, the first water flow port 112 is located on the first water flow plate 110, and the second water flow port 122 is located on the second water flow plate 120. Furthermore, the first water flow plate 110 has a third water flow port 113 that communicates with the second water flow port 122.

[0058] In this embodiment, the first water outlet 112 and the third water outlet 113 are respectively located on the corresponding first through hole 111 , and the second water outlet 122 is located on the second through hole 121 .

[0059] In this embodiment, the elastic member 130 has a circular shape at either end of its axial cross-section. Specifically, when the first water pass plate 110 serves as the outlet, the elastic member 130 is in the first position. At this point, the elastic member 130 presses against the inner wall of the second through hole 121 to block the third water outlet 113. Water flows in through the second water outlet 122 of the second water pass plate 120 and out through the first water outlet 112 (i.e., out through the first through hole 111). This achieves high-pressure water discharge over a small area. When the water outlet structure 100 flips 180°, the first water pass plate 110 serves as the water inlet. Under the impact of the water flow, the elastic member 130 presses against the insert 140, placing the elastic member 130 in the second position and slightly deforming. The second through-hole 121 connects with the first through-hole 111, allowing water to flow in through the first and third water passes 112, 113, and out through the second water pass 122, achieving a wide-area water outlet. During the flipping process of the water outlet structure 100, the change in position of the elastic member 130 causes the water flow area of ​​the second through-hole 121 to change, thereby increasing the total water flow area of ​​the first and second through-holes 111, 121. Furthermore, because the cross-sectional area of ​​the first water pass 112 is larger than that of the second water pass 122, the water pressure and the shape of the water splashes during the outlet also change.

[0060] 5-6 , the third embodiment of the present invention is as follows:

[0061] The difference between this embodiment and the second embodiment lies in that two elastic members 130 and two coaxially arranged third water outlets 113 with different diameters are provided.

[0062] In this embodiment, the water outlet device includes a coaxially arranged first water pass plate 110 and a second water pass plate 120 and an elastic member 130; the first water pass plate 110 has at least one first through hole 111; the second water pass plate 120 has at least one second through hole 121; the elastic member 130 is arranged in the second through hole 121; when the position of the elastic member 130 in the second through hole 121 changes, the total water flow area of ​​the first through hole 111 and the second through hole 121 changes.

[0063] In this embodiment, a water flow cavity is formed between the first water flow plate 110 and the second water flow plate 120. An insert 140, which is a flow-rectifying mesh, is interposed between the first and second water flow plates 110, 120. The water outlet structure 100 has a first water flow port 112 and a second water flow port 122 on either side of the axial direction, respectively. Specifically, the first water flow port 112 is located on the first water flow plate 110, while the second water flow port 122 is located on the second water flow plate 120. Furthermore, the first water flow plate 110 has a third water flow port 113, which is connected to the second water flow port 122.

[0064] In this embodiment, the first water outlet 112 and the third water outlet 113 are respectively located on the corresponding first through hole 111 , and the second water outlet 122 is located on the second through hole 121 .

[0065] In this embodiment, the elastic member 130 has a circular shape at either end of its axial cross-section. Specifically, when the first water pass plate 110 serves as the outlet, the elastic member 130 is in the first position. At this point, the elastic member 130 presses against the inner wall of the first through hole 111 to block the third water outlet 113. Water flows in through the second water outlet 122 of the second water pass plate 120 and out through the first water outlet 112 (i.e., out of the first through hole 111). This achieves high-pressure water discharge over a small area. When the water outlet structure 100 flips 180°, the first water pass plate 110 serves as the water inlet. Under the impact of the water flow, the elastic member 130 presses against the insert 140, placing the elastic member 130 in the second position. The elastic member 130 slightly deforms, connecting the first through-hole 111 to the second through-hole 112. Water flows in through the first water pass 112 and the two third water pass 113 and out through the second water pass 122, achieving a large-area water outlet. During the flipping process of the water outlet structure 100, the position of the elastic member 130 changes, causing the water flow area of ​​the first through-hole 111 to change. This, in turn, increases the total water flow area of ​​the first and second through-holes 111, and because the cross-sectional area of ​​the first water pass 112 is larger than that of the second water pass 122, the water pressure and the shape of the water splashes during the outlet also change.

[0066] 7-8 , the fourth embodiment of the present invention is as follows:

[0067] In this embodiment, the water outlet structure 100 includes a first water pass plate 110, a second water pass plate 120 and an elastic member 130; the first water pass plate 110 has at least one first through hole 111; the second water pass plate 120 has at least one second through hole 121; and the elastic member 130 is arranged in the second through hole 121.

[0068] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120. A first water passage 112 and a second water passage 122, which communicate with the first water passage 112, are respectively provided on either side of the water outlet structure 100 in the axial direction. Specifically, the first water passage 112 is located on the first water passage plate 110, and the second water passage 122 is located on the second water passage plate 120, with the first and second water passages 112 and 122 being coaxially arranged. Furthermore, a third water passage 113 is provided on the first water passage plate 110, and a fourth water passage 123 is provided on the second water passage plate 120.

[0069] In this embodiment, either end of the axial cross-section of the elastic member 130 is circular. Specifically, when the first water pass plate 110 serves as the outlet, the elastic member 130 is in the first position. At this point, the elastic member 130 presses against one end of the inner wall of the first through hole 111, blocking the third water outlet 113. Water flows in through the second water outlet 122 and the fourth water outlet 123 of the second water pass plate and out through the first water outlet 112 (i.e., out of the first through hole 111). This creates a first type of high-pressure water spray, namely, high-pressure columnar water. When the water outlet structure 100 flips 180°, the first water plate 110 serves as the water inlet. Under the impact of the water flow, the elastic member 130 presses against the other end of the inner wall of the second through hole 121 and blocks the fourth water outlet 123. That is, the elastic member 130 is in the second position. Water flows in from the first and third water outlets 112 and 113 and flows out from the second water outlet 122, forming a second type of high-pressure water splash, namely, blade water. During the flipping of the water outlet structure 100, the position of the elastic member 130 changes, causing the water to flow out from outlets with different shapes. Therefore, the shape of the water splash changes during the water outlet. The shape of the water splash depends on the cross-sectional shapes of the first and second water outlets 112 and 122. In addition to the two types of water splashes mentioned above, other types of water splashes can also be formed.

[0070] 9 to 12 , the fifth embodiment of the present invention is as follows:

[0071] The difference between this embodiment and the third embodiment is that the embedding part 140 is not provided.

[0072] In this embodiment, the water outlet structure 100 includes a first water pass plate 110, a second water pass plate 120 and an elastic member 130; the first water pass plate 110 has at least one first through hole 111; the second water pass plate 120 has at least one second through hole 121; the elastic member 130 is arranged in the second through hole 121; when the position of the elastic member 130 in the second through hole 121 changes, the total water flow area of ​​the first through hole 111 and the second through hole 121 changes.

[0073] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120. A first water passage 112 and a second water passage 122 communicating with the first water passage 112 are respectively provided on either side of the water outlet structure 100 in the axial direction. Specifically, the first water passage 112 is located on the first water passage plate 110, and the second water passage 122 is located on the second water passage plate 120. Furthermore, two third water passages 113 are provided on the first water passage plate 110, and a fourth water passage 123 is provided on the second water passage plate 120.

[0074] In this embodiment, the first water outlet 112 and the third water outlet 113 are respectively located on the corresponding first through hole 111 , and the second water outlet 122 and the fourth water outlet 123 are respectively located on the corresponding second through hole 121 .

[0075] In this embodiment, the elastic member 130 has a circular shape at either end of its axial cross-section. Specifically, when the first water pass plate 110 serves as the outlet, the elastic member 130 is in the first position. At this point, the elastic member 130 presses against the inner wall of the first through hole 111, blocking the third water outlet 113. Water flows in through the second and fourth water outlets 122 and 123 of the second water pass plate 120 and out through the first water outlet 112 (i.e., out through the first through hole 111 of the first water outlet member). This creates a first type of high-pressure water spray, namely, high-pressure columnar water. When the water outlet structure 100 flips 180°, the first water pass plate 110 serves as the water inlet side. At this time, under the impact of the water flow, the elastic member 130 presses against the inner wall of the second through hole 121 and blocks the fourth water outlet 123, that is, the elastic member 130 is in the second position, and the water flows in from the first water outlet 112 and the third water outlet 113 and flows out from the second water outlet 122, forming a second high-pressure water splash, namely blade water. During the flipping process of the water outlet structure 100, due to the change in the position of the elastic member 130, the water flow area of ​​the first through hole 111 and the second through hole 121 changes. Specifically, the water flow originally flows in from a fourth water outlet 123 and flows out from the first water outlet 112, but changes to flowing in from at least two third water outlets 113 and flowing out from the second water outlet 122, so that the water flows out from water outlets with different shapes. Therefore, the shape of the water splash changes when the water is discharged. The shape of the water splash depends on the cross-sectional shape of the first water outlet 112 and the second water outlet 122. In addition to the above two types of water splashes, other forms of water splashes can also be formed.

[0076] In this embodiment, the fourth water outlet 123 can be disposed at a position opposite to the third water outlet 113 , or can be staggered with the third water outlet 113 in the axial direction of the water outlet structure 100 .

[0077] 13-14 , the sixth embodiment of the present invention is as follows:

[0078] The difference between the present invention and the fifth embodiment is that the present invention has two coaxially arranged fourth water outlets 123 .

[0079] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
