[0001] The present invention relates to the field of bathroom water outlet structures, in particular to a water outlet device and a bubbler. Background Art
[0002] In the prior art, Chinese patent document CN219280829U discloses a new water outlet structure that changes the water spray by flipping the water spray former, but this solution has the following problems: in order to ensure the stability of the connection between the inner liner and the outer shell, the outer shell and the inner components of the inner liner have more matching relationships, and Example 3 also needs to limit the seal by relying on the matching relationship between the outer shell and the inner component, which puts forward higher requirements on the accuracy of the matching between the two. Technical issues
[0003] The technical problem to be solved by the present invention is to provide a water outlet device and a bubbler, reduce the matching accuracy requirements between the outer shell and the inner liner, and improve the compatibility of the product. Technical Solutions
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0005] The water outlet device includes a water outlet panel and an inner liner. The water outlet panel is reversibly connected to the water outlet end of the inner liner to form different water splashes. A boss is provided on the outside of the water inlet end of the inner liner. The distance from the outer wall of the boss to the axial center of the inner liner is greater than the radius of the water outlet end of the inner liner.
[0006] Furthermore, at least two bosses are provided, and the bosses are arranged at equal intervals around the axis of the inner container.
[0007] Furthermore, the boss is annular.
[0008] Furthermore, a sealing member is provided on a side of the boss away from the water outlet end of the inner container.
[0009] In order to solve the above technical problems, another technical solution adopted by the present invention is:
[0010] A bubbler, comprising a housing and the water outlet device as described above;
[0011] The circumferential side wall of the shell has a step surface, and the inner diameter of the step surface is larger than the outer diameter of the inner container;
[0012] In the axial direction of the housing, the boss presses against the step surface.
[0013] Furthermore, the outer diameter of the boss is smaller than or equal to the outer diameter of the step surface.
[0014] Furthermore, the step surface is annular.
[0015] Furthermore, at least two step surfaces are provided, and each step surface matches one boss.
[0016] Furthermore, at least two bosses are provided, and the bosses are arranged at equal intervals around the axis of the inner container.
[0017] Furthermore, the boss is annular.
[0018] Furthermore, the inner wall of the shell is provided with an internal thread near the water inlet end, and the internal thread is located between the step surface and the end surface of the water inlet end of the shell;
[0019] Alternatively, an outer wall of the housing is provided with an external thread near the water inlet end, and an edge of the external thread near one end of the housing water outlet end is lower than the step surface.
[0020] Furthermore, when the water outlet end of the inner container protrudes outward from the water outlet end surface of the outer shell, the distance between the water outlet end surface of the inner container and the water outlet end surface of the outer shell is less than 10 mm. Beneficial effects
[0021] The beneficial effects of the present invention are: by arranging a boss on the inner tank of the water outlet device to press against the water inlet end of the outer shell, the connection structure is simplified, so that the water outlet device of this scheme can be adapted to most cylindrical straight-tube outer shells with a one-step, and the structural requirements of the outer shell are relatively low. Relying on the cooperation between the faucet water outlet and the boss and the step surface, it can be ensured that the inner tank is always stably hung in the outer shell and is sufficient to resist the impact force on the inner tank when the faucet outputs high-pressure water; at the same time, this scheme does not have any matching accuracy requirements for the internal components of the outer shell and the inner tank, and therefore has very low requirements for the processing accuracy of the outer shell; in addition, the shape of the water splash can be changed by flipping the water outlet panel, and even if the outer shell does not rotate, the water outlet device can still form a variety of water outlet forms.

[0032] 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.
[0033] Referring to Figures 1 to 5, a bubbler includes a shell 1 and a water outlet device 2. The circumferential side wall of the shell 1 has a stepped surface 11; the water outlet device 2 includes a water outlet panel 21 and an inner liner 22. The water outlet panel 21 is reversibly connected to the water outlet end of the inner liner 22 to form different water sprays. A boss 221 is provided on the outside of the water inlet end of the inner liner 22. The distance from the outer wall of the boss 221 to the axial center of the inner liner 22 is greater than the radius of the water outlet end of the inner liner 22. In the axial direction of the shell 1, the boss 221 presses against the stepped surface 11.
[0034] It can be understood that by providing the boss 221, the boss 221 is pressed against the water inlet end of the outer shell 1. By relying on the cooperation between the faucet and the boss 221, the impact of the water pressure on the inner tank 22 can be resisted, ensuring that the inner tank 22 is always hung in the outer shell 1. After simplifying the connection structure, the inner tank 22 and the outer shell 1 can still maintain a stable connection relationship. In addition, the shape of the water splash can be changed by flipping the water outlet panel 21. Even if the outer shell 1 does not rotate, the water outlet device 2 can still form a variety of water outlet forms. Among them, the distance from the outer wall of the boss 221 to the axial center of the inner liner 22 is greater than the radius of the water outlet end of the inner liner 22, which enables the boss 221 to cooperate with the step surface whose inner diameter is greater than the inner liner 22 but smaller than the boss 221. The optimal solution is to form a gap between the outer wall of the inner liner 22 and the inner wall of the step surface. This can reduce the accuracy requirements of the matching dimensions between the outer wall of the inner liner 22 and the inner wall of the outer shell 1 during the assembly process, thereby reducing the molding and processing accuracy requirements of the inner wall surface of the outer shell 1, reducing costs and improving production efficiency.
[0035] In some embodiments, the inner wall of the housing 1 is provided with an internal thread near the water inlet end, and the internal thread is located between the step surface 11 and the end surface of the water inlet end of the housing 1, so as to facilitate screwing in a water outlet device with an external thread, such as a quick-open faucet, basin faucet, kitchen faucet, or shower faucet; or, the outer wall of the housing 1 is provided with an external thread near the water inlet end, and the edge of the external thread near the water outlet end of the housing 1 is lower than the step surface 11, so as to facilitate screwing in a water outlet device with an internal thread, such as a basin faucet. The housing 1 can be connected to different water outlet devices through the internal or external threads, which improves the connection adaptability between the housing 1 and different water outlet devices while also allowing the inner tank to be hidden within the housing, making the shape of the water outlet devices more unified.
[0036] In some embodiments, a seal 3 is provided on the side of the boss 221 away from the water outlet of the inner liner 22. When the outer shell 1 is threadedly connected to the water outlet of the water outlet device, the seal 3 is sandwiched between the water outlet device 2 and the water outlet, allowing the water outlet device 2 to maintain a stable connection with the outer shell 1 while improving the sealing between the outer shell 1 and the water outlet device 2 and the water outlet. This allows all water to pass through the inner liner 22 and be discharged from the water outlet panel 21, preventing water from leaking through the gaps between the outer shell 1 and the water outlet device 2, or between the internal components of the inner liner 22.
[0037] In some embodiments, the step surface 11 is annular, and correspondingly, a plurality of equally spaced bosses 221 may be provided to cooperate with the step surface 11, or an annular boss 221 may be provided to cooperate with the step surface 11. When the boss 221 is annular, the outer diameter of the boss 221 is less than or equal to the outer diameter of the step surface 11. In the above two embodiments, when both the step surface 11 and the boss 221 are annular, the boss 221 can maintain the most stable positional relationship with the step surface 11.
[0038] In some embodiments, at least two bosses 221 are provided, and the bosses 221 are arranged at equal intervals around the axis of the inner liner 22. Correspondingly, at least two step surfaces 11 are provided, and each step surface 11 matches a boss 221. In this solution, at least two bosses 221 are provided, and the equal intervals between them are used to balance the forces at various positions of the water outlet device 2 in the circumferential direction, ensuring the stability between the water outlet device 2 and the housing 1. This solution is suitable for a specific installation angle defined between the housing 1 and the water outlet device 2.
[0039] In some embodiments, at the water outlet end of the water outlet device 2, there is a gap between the outer wall of the inner tank 22 and the inner wall of the outer shell 1 to facilitate the assembly of the inner tank 22 and the outer shell 1, thereby reducing the requirements for part accuracy and the matching accuracy between parts, reducing costs and improving production efficiency.
[0040] In some embodiments, a sealing ring 4 is further included. The inner wall of the water outlet end of the water outlet device 2 has a groove 41. The sealing ring 4 is embedded in the groove 41. The water outlet panel 21 is pressed against the inner ring of the sealing ring 4 and the water outlet panel 21 never contacts the inner wall of the water outlet device 2, thereby avoiding interference between the water outlet panel 21 and the water outlet device 2, ensuring the smoothness of the rotation of the water outlet panel 21, and at the same time ensuring the sealing of the water outlet device 2, thereby avoiding water seepage from places other than the drainage hole of the water outlet panel 21.
[0041] In some embodiments, when the water outlet end of the inner tank 22 protrudes from the end face of the water outlet end of the outer shell 1, the distance between the end face of the water outlet end of the inner tank 22 and the end face of the water outlet end of the outer shell 1 is less than 10 mm. Preferably, the distance is 1 to 3 mm. In order to prevent the water flow with a specific splash generated by the water outlet panel 21 from being interfered with by the outer shell 1 during the outward discharge process, the water outlet end of the inner tank 22 will slightly protrude from the end face of the water outlet end of the outer shell 1. If the distance between the end face of the water outlet end of the inner tank 22 and the end face of the water outlet end of the outer shell 1 is too large, the overall shape of the bubbler and the water outlet device will be limited, and if applied to a basin faucet, the water outlet space under the faucet, which is not high to begin with, will become even smaller, affecting the user experience. Therefore, limiting the distance to within 10 mm can ensure that the water outlet device 2 has the best water outlet distance, and the distance of 1 to 3 mm can be used as the optimal choice.
[0042] 1 to 3 , the first embodiment of the present invention is as follows:
[0043] A bubbler includes a shell 1 and a water outlet device 2. The circumferential side wall of the shell 1 has a step surface 11; the water outlet device 2 includes a water outlet panel 21 and an inner liner 22. The water outlet panel 21 is reversibly connected to the water outlet end of the inner liner 22. The two axial water flow surfaces of the water outlet panel 21 respectively have different rectifying panels. When different rectifying panels drain water to the outside, different water sprays can be formed. A boss 221 is provided on the outside of the water inlet end of the inner liner 22. The distance r from the outer wall of the boss 221 to the axial center of the inner liner 22 is greater than the radius R of the water outlet end of the inner liner 22. In the axial direction of the shell 1, the boss 221 is pressed against the step surface 11, and the inner diameter of the step surface 11 is greater than the outer diameter of the inner liner 22. In order to prevent the water flow with a specific splash formed by the water outlet panel 21 (such as large-angle scattered atomized water or wide-angle shower water) from being interfered with by the outer shell 1, the water outlet end of the inner liner 22 protrudes outward from the end surface of the water outlet end of the outer shell 1, and the distance h between the end surface of the water outlet end of the inner liner 22 and the end surface of the water outlet end of the outer shell 1 is 1 mm.
[0044] In this embodiment, an internal thread is provided on the outer wall of the shell 1 near the water inlet end, and a seal 3 is provided on the side of the boss 221 away from the water outlet end of the inner tank 22. Part of the seal 3 is pressed against the boss 221, and the remaining part is pressed against the water inlet end of the inner tank 22. When the shell 1 is connected to the water outlet device through the internal thread, the end of the external thread of the water outlet device will squeeze the seal 3 to cause it to elastically deform. The seal 3 is clamped between the water outlet device and the parts of the boss 221 and the water inlet end of the inner tank 22.
[0045] In this embodiment, the step surface 11 is annular, and an annular boss 221 is provided to cooperate with the step surface 11 . The outer diameter of the boss 221 is slightly smaller than the outer diameter of the step surface 11 .
[0046] In this embodiment, a sealing ring 4 is also included. The inner wall of the water outlet end of the water outlet device 2 has a groove 41. The sealing ring 4 is embedded in the groove 41. The water outlet panel 21 is pressed against the inner circle of the sealing ring 4 and the water outlet panel 21 never contacts the inner wall of the water outlet device 2.
[0047] 4 and 5 , the second embodiment of the present invention is as follows:
[0048] The difference between this embodiment and the first embodiment is that the outer wall of the housing 1 is provided with an external thread near the water inlet end. The edge of the external thread near the water outlet end of the housing 1 is lower than the step surface 11, that is, the position of the external thread closest to the water outlet end of the housing 1, and in the axial direction of the water outlet device 2, there is a distance d between the side of the seal 3 away from the boss 221 and the end face of the water inlet end of the housing 1. The distance d is used to ensure that the seal 3 can protrude from the end face of the water inlet end of the housing 1 to press against the water outlet of the faucet to achieve sealing. Preferably, this distance is less than the thickness of the seal 3, so that the end face of the housing 1 is higher than the bottom of the seal 3, thereby radially limiting the seal 3 and preventing the seal 3 from accidentally falling off before the aerator is installed on the faucet. The above description is only an embodiment of the present invention and does not limit the scope of the patent of the present invention. Any equivalent transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in related technical fields, is also included in the scope of patent protection of the present invention.
