Description

Technical Field

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

[0002] In sanitary ware products, in order to ensure that the final discharged water flow can meet the water demand of the preset form and usage scenario, especially it must also meet the flow discharge standards set by different countries and regions for sanitary ware products, sanitary ware products usually need to be equipped with a flow control device upstream of the water outlet. For example, by setting a flow controller (also known as a flow regulator, water-saving sheet, water-saving sheet or flow-limiting sheet, etc.) in a faucet or shower head, it can be used to limit the flow or even keep the flow constant. For example, the solutions disclosed in patents such as CN201973314U, CN203176476U, CN1759268A, and CN102788178A all belong to 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. The solution of CN140104169A also needs to adjust the position of the water outlet surface to achieve input flow control of different water outlet surfaces, and the structure is relatively complicated. Summary of the invention

[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.

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

[0006] A water outlet structure comprises a first water passing plate, a second water passing 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 passage cavity is formed between the first water passage plate and the second water passage plate, and the elastic member is disposed in the water passage 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.

[0017] Water outlet structure Water outlet structure

[0018] The beneficial effect of the present invention is that the elastic member changes its position in the water outlet structure or deforms when it is turned over or affected by the changing water flow, so as to change the total water flow area of ​​the first through hole and the second through hole, thereby achieving flow control. Therefore, the water outlet structure and the water outlet device in the present invention can not only change the water outlet surface to form different water splashes, but also achieve flow regulation.

[0036] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0037] Please refer to Figure 1-Figure 14A water outlet device includes a water outlet body and a water outlet structure 100; the water outlet structure 100 is relatively rotatably connected to the water outlet end of the water outlet body, and the water outlet structure 100 can rotate around an axis perpendicular to the water flow direction 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 pass cavity is formed between the first water pass plate 110 and the second water pass plate 120, and an elastic member 130 is arranged in the water pass cavity; when the elastic member 130 is deformed or the relative position of the elastic member 130 and at least part of the first through hole 111 and / or the second through hole 121 changes, the total water pass area of ​​the first through hole 111 and / or the total water pass area of ​​the second through hole 121 changes.

[0038] Among them, all the water holes on the first water pass plate 110 are located in the corresponding first through hole 111, and all the water holes on the second water pass plate 120 are located in the corresponding second through hole 121. The first water pass plate 110 will serve as the water inlet side or the water outlet side during the flipping process. When the first water pass plate 110 is the water inlet side, the second water pass plate 120 is the water outlet side. When the first water pass plate 110 is the water outlet side, the second water pass plate 120 is the water inlet side.

[0039] 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 fit with the water inlet end of the water inlet body.

[0040] It is understandable that the elastic member 130 will change its position in the water outlet structure 100 or deform when it is turned over or affected by the changing water flow (the deformation of the elastic member 130 includes the deformation when it is affected by external force and the reset when the external force is removed) to change 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 in the present invention can not only change the water outlet surface to form different water splashes, but also achieve flow regulation.

[0041] In some embodiments, the outer surface of the water outlet structure 100 has an incomplete spherical surface, which can be matched with a water outlet body with a ball socket, and can also be provided with threads on its outer surface for direct connection with the water outlet of a faucet, and can also be installed at the water inlet of a shower or the water outlet of a shower as a flow controller, and the water outlet state of the shower or shower can be changed by switching the water outlet side and the water inlet side. Alternatively, the outer wall of the water outlet structure is a straight cylinder or an arc.

[0042] In some embodiments, the elastic member 130 can be separated from or pressed against the side wall of the first through hole 111. When the elastic member 130 is deformed, the elastic member 130 can be separated from or pressed against the side wall of the first through hole 111 to change the water flow area of ​​the first through hole 111, thereby changing the total water flow area of ​​the first through hole 111 and the second through hole 121.

[0043] 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 , and the switching between the first position and the second position is generated by flipping the water outlet structure 100 .

[0044] In some embodiments, at least two first through holes 111 or at least two second through holes 121 can be simultaneously changed in water flow area by one of the elastic members 130, so that the water flow during water discharge remains constant, while ensuring the effectiveness of the change in water flow area, so as to ensure the flow regulation effect and the water splash shaping effect. When the water flow area of ​​one of the first through hole 111 and the second through hole 121 is changed, the total water flow area of ​​the first through hole 111 and the second through hole 121 will change.

[0045] In some embodiments, when the elastic member 130 presses against the mouth of the first through hole 111 and / or the second through hole 121 facing the water passage cavity, the elastic member 130 is located at the first position, the water passage area of ​​the first through hole 111 and / or the second through hole 121 is the smallest, 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 a smooth surface, the elastic member 130 presses against the inner wall of the first through hole 111 and / or the second through hole 121 to make the water passage area of ​​the first through hole 111 and / or the second through hole 121 zero; and when the surface of the first through hole 111 and / or the second through hole 121 is provided with 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 passage area is small at this time.

[0046] In some embodiments, when the elastic member 130 is deformed or when the elastic member 130 moves toward the direction close to 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 direction close to the second water pass plate 120, the elastic member 130 can move to the second position and block at least one second through hole 121. On the contrary, when the original position of the elastic member 130 is closer to the second water pass plate 120, the elastic member 130 is deformed or when the elastic member 130 moves toward the direction close to 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 direction close to the first water pass plate 110, the elastic member 130 can move to the second position and block at least one first through hole 111.

[0047] In some embodiments, an insert 140 is further disposed between the first water pass plate 110 and the second water pass plate 120; when the elastic member 130 is deformed or when the elastic member 130 moves toward the direction close to the first water pass plate 110 or the second water pass plate 120, the elastic member 130 and the insert 140 are pressed against each other. The support of the insert 140 for the elastic member 130 can maintain a water flow gap between the elastic member 130 and the first water pass plate 110 and the second water pass plate 120, thereby maximizing the water flow area. On the contrary, when the original position of the elastic member 130 is on the side closer to the second water pass plate 120, the elastic member 130 is deformed or when the elastic member 130 moves toward the direction close to the first water pass plate 110, the elastic member 130 and the insert 140 are pressed against each other. The insert 140 is a boss, a rectifying net or a rectifying grid.

[0048] In some embodiments, the two sides of the water outlet structure 100 in the axial direction respectively have a first water outlet 112 and a second water outlet 122 that can communicate with the first water outlet 112; specifically, the first water outlet 112 is located on the first water plate 110, and the second water outlet 122 is located on the second water plate 120. The first water outlet 112 is located on one of the first through holes 111, and the second water outlet 112 is located on one of the second through holes 121; in the radial direction of the water outlet structure 100, the cross-section of the first water outlet 112 is different from that of the second water outlet 122, so that when the water flows out from different water outlets, there are different water outlet states. In addition, the first water 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 other first through holes 111.

[0049] In some embodiments, the elastic member 130 is annular, and either end of the axial section of the elastic member 130 is circular, U-shaped, or Y-shaped. When the elastic member 130 is of different structures, its deformation amount and the changed position are different. Specifically, when either end of the axial 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 section of the elastic member 130 is circular, the deformation amount of the elastic member 130 when deformed is the smallest, in order to ensure the change of the water flow area, it is achieved by changing the position, so the position change in the water outlet structure 100 is the largest.

[0050] Please refer to Figure 1-Figure 2 , Embodiment 1 of the present invention is:

[0051] 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.

[0052] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120, and an insert 140 is further provided between the first water passage plate 110 and the second water passage plate 120. The insert 140 is a boss, and a water filter 150 is provided on the second water passage plate 120. The two sides of the water outlet structure 100 in the axial direction respectively have a first water passage 112 and a second water passage 122 that can communicate with the first water passage 112; 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. In addition, the first water passage plate 110 also has a third water passage 113 that can communicate with the second water passage 122.

[0053] 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 121 is located on the second through hole 121 .

[0054] In this embodiment, either end of the axial section of the elastic member 130 is in a Y-shape. Specifically, when the first water pass plate 110 is used as the water outlet side, the elastic member 130 is located at the first position, at which time the elastic member 130 presses against the inner wall of the first through hole 111 to block the third water pass port 113, and water flows in from the second water pass port 122 of the second water pass plate 120 and flows out from the first water pass port 112 (i.e., flows out from the first through hole 111), and at this time, high-pressure water is discharged in a small area. When the water outlet structure 100 is turned over 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 insert member 140, that is, the elastic member 130 is located at the second position, and the elastic member 130 is deformed in the radial direction of the water outlet structure 100, and the second through hole 121 is connected with the first through hole 111, that is, the water flows in from the first water pass port 112 and the third water pass port 113 and flows out from the second water pass port 122, so that a large area of ​​water is discharged. During the turning process of the water outlet structure 100, due to the deformation of the elastic member 130 and the slight position change of the elastic member 130, the water passing area of ​​the first through hole 111 changes, and the total water passing area of ​​the first through hole 111 and the second through hole 121 increases, and because the cross-sectional area of ​​the first water pass port 112 is larger than the cross-sectional area of ​​the second water pass port 122, the water pressure and the shape of the water splash during the water discharge also change.

[0055] Please refer to Figure 3-Figure 4 , Embodiment 2 of the present invention:

[0056] The difference between this embodiment and the first embodiment lies in that the structure of the elastic member 130 , the structure of the first water passing plate 110 and the structure of the second water passing plate 120 are different.

[0057] 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 pass area of ​​the first through hole 111 and the second through hole 121 changes.

[0058] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120, and the insert 140 is a rectifying net to filter impurities in the water and to support the elastic member 130. The two sides of the water outlet structure 100 in the axial direction respectively have a first water passage 112 and a second water passage 122 that can communicate with the first water passage 112; 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. In addition, the first water passage plate 110 also has a third water passage 113 that can communicate with the second water passage 122.

[0059] 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 121 is located on the second through hole 121 .

[0060] In this embodiment, either end of the axial section of the elastic member 130 is circular. Specifically, when the first water pass plate 110 is used as the water outlet side, the elastic member 130 is located at the first position, at which time the elastic member 130 presses against the inner wall of the second through hole 121 to block the third water pass port 113, and water flows in from the second water pass port 122 of the second water pass plate 120 and flows out from the first water pass port 112 (i.e., flows out from the first through hole 111), and at this time, high-pressure water is discharged in a small area. When the water outlet structure 100 is flipped 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 insert 140, that is, the elastic member 130 is located in the second position, and the elastic member 130 is slightly deformed, and the second through hole 121 is connected with the first through hole 111, that is, the water flows in from the first water pass 112 and the third water pass 113 and flows out from the second water pass 122, so that a large area of ​​water is discharged. During the flipping process of the water outlet structure 100, due to the change in the position of the elastic member 130, the water pass area of ​​the second through hole 121 changes, and then the total water pass area of ​​the first through hole 111 and the second through hole 121 increases, and because the cross-sectional area of ​​the first water pass 112 is larger than the cross-sectional area of ​​the second water pass 122, the water pressure and the shape of the water splash during the water discharge also change.

[0061] Please refer to Figure 5-Figure 6 , Embodiment 3 of the present invention is:

[0062] 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.

[0063] In this embodiment, the water outlet device includes a first water pass plate 110 and a second water pass plate 120 and an elastic member 130 which are coaxially arranged; 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.

[0064] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120, and an insert 140 is sandwiched between the first water passage plate 110 and the second water passage plate 120, and the insert 140 is a rectifying net. The two sides of the water outlet structure 100 in the axial direction respectively have a first water passage 112 and a second water passage 122 that can communicate with the first water passage 112; 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. In addition, the first water passage plate 110 also has a third water passage 113 that can communicate with the second water passage 122.

[0065] 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 121 is located on the second through hole 121 .

[0066] In this embodiment, either end of the axial section of the elastic member 130 is circular. Specifically, when the first water pass plate 110 is used as the water outlet side, the elastic member 130 is located at the first position, at this time, the elastic member 130 presses against the inner wall of the first through hole 111 to block the third water pass port 113, and water flows in from the second water pass port 122 of the second water pass plate 120 and flows out from the first water pass port 112 (that is, flows out from the first through hole 111), at this time, high-pressure water is discharged in a small area. When the water outlet structure 100 is flipped 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 insert 140, that is, the elastic member 130 is located in the second position, and the elastic member 130 is slightly deformed, and the first through hole 111 is connected with the first through hole 111, that is, the water flows in from the first water pass port 112 and the two third water pass ports 113 and flows out from the second water pass port 122, so that a large area of ​​water is discharged. During the flipping process of the water outlet structure 100, due to the change in the position of the elastic member 130, the water pass area of ​​the first through hole 111 changes, and then the total water pass area of ​​the first through hole 111 and the second through hole 121 increases, and because the cross-sectional area of ​​the first water pass port 112 is larger than the cross-sectional area of ​​the second water pass port 122, the water pressure and the shape of the water splash during the water discharge also change.

[0067] Please refer to Figure 7-Figure 8 , Embodiment 4 of the present invention is:

[0068] 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 disposed in the second through hole 121.

[0069] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120. The two sides of the water outlet structure 100 in the axial direction respectively have a first water passage 112 and a second water passage 122 that can communicate with the first water passage 112; 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, and the first water passage 112 and the second water passage 122 are coaxially arranged. In addition, a third water passage 113 is also arranged on the first water passage plate 110, and a fourth water passage 123 is also arranged on the second water passage plate 120.

[0070] In this embodiment, either end of the axial section of the elastic member 130 is circular. Specifically, when the first water pass plate 110 is used as the water outlet side, the elastic member 130 is located at the first position. At this time, the elastic member 130 presses against one end of the inner wall of the first through hole 111 to block the third water pass port 113. Water flows in from the second water pass port 122 and the fourth water pass port 123 of the second water pass plate and flows out from the first water pass port 112 (i.e., flows out from the first through hole 111). At this time, the first high-pressure water splash, i.e., high-pressure columnar water, is formed. When the water outlet structure 100 flips 180°, the first water 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 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 located 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 type of high-pressure water splash, namely, blade water. During the flipping of the water outlet structure 100, due to the change in the position of the elastic member 130, the water flows out from water outlets with different shapes, so the shape of the water splash changes when the water is discharged, and 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.

[0071] Please refer to Figure 9-12 , Embodiment 5 of the present invention is:

[0072] The difference between this embodiment and the third embodiment is that the embedding part 140 is not provided.

[0073] 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 pass area of ​​the first through hole 111 and the second through hole 121 changes.

[0074] In this embodiment, a water passage cavity is formed between the first water passage plate 110 and the second water passage plate 120, and the two sides of the water outlet structure 100 in the axial direction respectively have a first water passage 112 and a second water passage 122 that can communicate with the first water passage 112; 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. In addition, 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.

[0075] 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 121 and the fourth water outlet 123 are respectively located on the corresponding second through hole 121 .

[0076] In this embodiment, either end of the axial section of the elastic member 130 is circular. Specifically, when the first water pass plate 110 is used as the water outlet side, the elastic member 130 is located at the first position, at this time, the elastic member 130 presses against the inner wall of the first through hole 111 to block the third water pass port 113, and water flows in from the second water pass port 122 and the fourth water pass port 123 of the second water pass plate 120 and flows out from the first water pass port 112 (i.e., flows out from the first through hole 111 of the first water outlet member), at this time, the first type of high-pressure water splash, i.e., high-pressure columnar water, is formed. 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 pass 123, that is, the elastic member 130 is located in the second position, and the water flows in from the first water pass 112 and the third water pass 113 and flows out from the second water pass 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 flows out. 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.

[0077] In this embodiment, the fourth water outlet 123 can be disposed at a position opposite to the third water outlet 113 , and can also be disposed offset from the third water outlet 113 in the axial direction of the water outlet structure 100 .

[0078] Please refer to Figure 13-14 , Embodiment 6 of the present invention is:

[0079] The difference between the present invention and the fifth embodiment is that the present invention has two coaxially arranged fourth water outlets 123 .

Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
