Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and particularly to the field of aerators. Background Technology

[0002] Aerators are commonly installed on bathroom products such as faucets and spray guns. They allow water and air to mix thoroughly, increasing the flushing power of the water while making the water flow gentle and splash-free. Many aerators now also feature water flow mode switching. These aerators typically consist of a water distribution body and a water outlet body, which can move relative to each other (usually rotating). The water outlet body has multiple water passages corresponding to different water flow methods, such as internal and external water inlets. The water distribution body has a jet channel. By moving the water distribution body and the water outlet body relative to each other, the jet channel switches to different water passages, thus changing the water flow mode.

[0003] To prevent accidental relative rotation of the water separator and outlet due to water flow reaction force, negative pressure, or user contact during use, a structure is needed to increase the relative rotational resistance between them. Current aerators typically provide this resistance through friction between the walls of the water separator and outlet, or friction between their walls and the sealing ring. However, the resistance provided by these methods is difficult to control, and it weakens due to wear over time, still making accidental rotation of the water separator and outlet likely. Furthermore, under smooth water flow, overflow and leakage between the water separator and outlet are generally unlikely. Therefore, many aerators have eliminated sealing structures such as sealing rings between the water separator and outlet. The rotational resistance between them is now largely provided by the friction between their walls, making them more prone to deformation, wear, and failure, severely impacting service life and user experience. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a bubbler that helps to reduce accidental rotation.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An aerator includes a water distribution body and a water outlet body rotatably connected together, wherein one of the water distribution body and the water outlet body is a first component and the other is a second component;

[0007] The first component is provided with a pressing part and an elastic part, and the second component is provided with a pressure-bearing surface corresponding to the pressing part. The elastic part presses the pressing part against the pressure-bearing surface, and the pressing part and the pressure-bearing surface can slide relative to each other as the water distribution body and the water outlet body rotate relative to each other.

[0008] Preferably, the elastic part is an elastic cantilever, and the pressing part is disposed on the cantilever.

[0009] Preferably, the pressing part is a boss provided on the cantilever.

[0010] Preferably, the pressing part and the elastic part are integral structures on the first component.

[0011] Preferably, the pressing part has a pressing surface that presses against the pressure bearing surface, and the pressing surface matches the pressure bearing surface.

[0012] Preferably, both the pressure-receiving surface and the pressure-bearing surface are planar.

[0013] Preferably, the water distribution body is provided with a first positioning protrusion, and the water outlet body is provided with a second positioning protrusion. The first positioning protrusion can abut against the second positioning protrusion as the water distribution body and the water outlet body rotate relative to each other to restrict the rotation of the water distribution body and the water outlet body.

[0014] Preferably, the water outlet body is provided with a first water passage and a first drainage chamber, and the main body of the water outlet body is provided with a first water outlet; the first water passage, the first drainage chamber and the first water outlet are connected sequentially from top to bottom; the side wall of the first drainage chamber has an impact zone, and the water outlet direction of the first water passage is towards the impact zone.

[0015] Preferably, the impact zone is located in the middle of the vertical direction of the sidewall of the first drainage cavity.

[0016] Preferably, the inner side of the lower section of the first water passage away from the impact zone is an inclined guide surface, the extended surface of the guide surface intersects the impact zone, and the inclination angle of the guide surface relative to the horizontal plane is 45 to 75 degrees.

[0017] The beneficial effects of this invention are as follows: In this aerator, the friction between the pressure-retaining part and the pressure-bearing surface can limit the accidental rotation of the water distribution body and the water outlet body caused by the reaction force of water flow, negative pressure force, or user bumps. Even if wear occurs after long-term use, the elastic part can keep the pressure-retaining part pressed against the pressure-bearing surface, thereby maintaining the friction between the pressure-retaining part and the pressure-bearing surface. This ensures the effect of limiting accidental rotation. Moreover, only an external force greater than the friction between the pressure-retaining part and the pressure-bearing surface needs to be applied to make the water distribution body and the water outlet body rotate relative to each other to switch modes. Thus, this aerator can effectively reduce accidental rotation, is more durable, helps to extend the service life of the product, and improve the user experience. Attached Figure Description

[0030] Reference Figures 1 to 5 In a preferred embodiment of the present invention, an aerator includes a water distribution body 10 and a water outlet body 20 rotatably connected together. One of the water distribution body 10 and the water outlet body 20 is a first component, and the other is a second component. The first component is provided with a pressing part 31 and an elastic part 32, and the second component is provided with a pressure-bearing surface 33 corresponding to the pressing part 31. The elastic part 32 presses the pressing part 31 against the pressure-bearing surface 33, and the pressing part 31 and the pressure-bearing surface 33 can slide relative to each other as the water distribution body 10 and the water outlet body 20 rotate relative to each other. In this aerator, the friction between the pressure-retaining part 31 and the pressure-bearing surface 33 can limit the accidental rotation of the water distribution body 10 and the water outlet body 20 caused by water flow reaction force, negative pressure force, or user bumps. Even if wear occurs after long-term use, the elastic part 32 can keep the pressure-retaining part 31 pressed against the pressure-bearing surface 33, thereby maintaining the friction between the pressure-retaining part 31 and the pressure-bearing surface 33. This ensures the effect of limiting accidental rotation. Moreover, only an external force greater than the friction between the pressure-retaining part 31 and the pressure-bearing surface 33 needs to be applied to make the water distribution body 10 and the water outlet body 20 rotate relative to each other to switch modes. Thus, this aerator can effectively reduce accidental rotation, is more durable, helps to extend the product's service life, and improve the user experience.

[0031] In this embodiment, the pressure-bearing part 31 and the elastic part 32 are provided on the water outlet 20, and the pressure-bearing surface 33 is provided on the water distribution body 10. That is, the water outlet 20 serves as the first component and the water distribution body 10 serves as the second component. In other embodiments, the two can be interchanged.

[0032] In this embodiment, a connecting hole 41 is provided inside the water outlet body 20, and a plurality of elastic hooks 42 are correspondingly provided on the water distribution body 10. These hooks 42 are hooked onto the lower surface of the connecting hole 41, thereby rotatably connecting the water distribution body 10 and the water outlet body 20. In other embodiments, the water outlet body 20 and the water distribution body 10 can also adopt other commonly used rotatable connection structures. For example, an annular groove can be provided on one of the water distribution body 10 and the water outlet body 20, and a slider that is slidably inserted into the groove can be provided on the other. These rotatable connection structures are widely used and can be flexibly selected by those skilled in the art.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0034] In this embodiment, the elastic part 32 is an elastic cantilever, and the pressing part 31 is disposed on the cantilever. The structure is simple and reliable, and easy to manufacture. In other embodiments, the elastic part 32 can also be selected from other commonly used elastic structures such as springs, spring sheets, and spring pads, or it can also be selected from other suitable elastic structures such as elastic arc plates connected to the first component at both ends; the pressing part 31 can also be selected from other suitable structures such as pressure blocks, or it can be selected from structures that are slidably disposed on the first component and pushed by the elastic part 32. Those skilled in the art can flexibly select and adjust these structures.

[0035] In this embodiment, the pressing part 31 is a boss provided on the cantilever, which facilitates the control of the contact surface between the pressing part 31 and the bearing surface 33, thereby controlling the magnitude of the friction force. It also provides a larger wear allowance, which helps to extend the service life. In other embodiments, the pressing part 31 may also be a non-protruding part on the cantilever, or a shim or the like may be provided on the cantilever as the pressing part 31.

[0036] In this embodiment, the pressing part 31 and the elastic part 32 are integral structures on the first component, which facilitates molding and assembly and helps reduce production costs. In practical applications, the pressing part 31, the elastic part 32, and the first component can be integrally molded by injection molding or other methods. In other embodiments, the pressing part 31 and the elastic part 32 can also be separate components and assembled on the first component, and are not limited to this.

[0037] In this embodiment, the pressing part 31 has a pressing surface that presses against the bearing surface 33. The pressing surface matches the bearing surface 33, which increases the contact area and thus increases the friction, thereby improving the anti-accidental rotation effect. In other embodiments, the pressing part 31 can also press against the bearing surface 33 by other means such as point contact or line contact.

[0038] In this embodiment, both the pressure-resistant surface and the pressure-bearing surface 33 are planar, facilitating processing and assembly. In this embodiment, the downward-facing outer end face of the water distributor 10 is used as the pressure-bearing surface 33, and the cantilever is also positioned on the outer side of the water outlet 20. Both are arc-shaped, ensuring contact during relative rotation of the water distributor 10 and the water outlet 20 without occupying internal space of the aerator. In other embodiments, the position and shape of the pressure-resistant part 31 and the pressure-bearing surface 33 can be flexibly adjusted as needed. For example, the arc-shaped side surface of either the water distributor 10 or the water outlet 20 can be used as the pressure-bearing surface 33, and the pressure-resistant surface can be correspondingly set as a matching arc-shaped surface. The pressure-resistant part 31 and the elastic part 32 can then be disposed inside the water distributor 10 or the water outlet 20, for example, on their interlocking structure. Those skilled in the art can flexibly select and adjust as needed.

[0039] In this embodiment, a first positioning protrusion 11 is provided on the water distribution body 10, and a second positioning protrusion 21 is provided on the water outlet body 20. The first positioning protrusion 11 can abut against the second positioning protrusion 21 as the water distribution body 10 and the water outlet body 20 rotate relative to each other, thereby restricting the rotation of the water distribution body 10 and the water outlet body 20. This allows for positioning of the relative angle between the water distribution body 10 and the water outlet body 20, facilitating user switching of water outlet modes. In this embodiment, there are two second positioning protrusions 21 on the water outlet body 20, and the first positioning module of the water distribution body 10 is located between the two second positioning protrusions 21, which can correspondingly position two water outlet modes. In other embodiments, the number and distribution of the first and second positioning blocks can also be flexibly adjusted as needed.

[0040] Reference Figures 3 to 5 In this embodiment, the water outlet 20 is provided with a first water passage 221 and a first drainage chamber 222, and the main body of the water outlet 20 is provided with a first water outlet 223; the first water passage 221, the first drainage chamber 222 and the first water outlet 223 are connected sequentially from top to bottom; the side wall of the first drainage chamber 222 has an impact area 23, and the water outlet direction of the first water passage 221 is towards the impact area 23. In this way, the water flow discharged from the first water passage 221 can collide with the impact area 23 on the side wall of the first drainage chamber 222 and be dispersed, which can effectively improve the uniformity of the water flow discharged from the first water outlet 223.

[0041] In this embodiment, the impact zone 23 is located in the middle of the vertical direction of the side wall of the first drainage chamber 222. This helps to ensure that the water flow in the first water passage 221 collides with the impact zone 23, reducing the possibility of the water flow bending and falling directly into the first outlet 223 when the water pressure is low. This makes the process more reliable and provides a larger dispersion space for the water flow, which helps to improve the uniformity of the water output. In other embodiments, the impact zone 23 may also be located in the upper or lower part of the first drainage chamber 222.

[0042] The inner surface of the lower section of the first water passage 221, away from the impact zone 23, is an inclined guide surface 24. The extended surface of the guide surface 24 intersects the impact zone 23, and the inclination angle α of the guide surface 24 relative to the horizontal plane is 45 to 75 degrees. This relatively small inclination angle can achieve a better balance between the water flow impact effect and the water flow passage within the first water passage 221, reducing the problem of backflow caused by the water flow being obstructed by the guide surface 24 within the first water passage 221, and also facilitating molding. In this embodiment, the inclination angle α is 68 degrees, which is more suitable for the size and internal structure of the conventional water outlet 20, and has less resistance to water flow. In other embodiments, the inclination angle of the guide surface 24 can be adjusted according to actual conditions and needs.

[0043] In this embodiment, the water outlet 20 further includes a second water passage 251, a second drainage chamber 252, and a second water outlet 253 connected in sequence. The first drainage chamber 222 is arranged in a ring around the second drainage chamber 252. The first water passage 221 and the second water passage 251 are alternately and evenly distributed around the vertical central axis of the water outlet 20. The water distribution body 10 is provided with a total water inlet 12 and a plurality of annularly arranged jet holes 13. As the water outlet 20 and the water distribution body 10 rotate relative to each other, the jet trajectory of the jet holes 13 can be switched to align with the first water passage 221 or the second water passage 251, thereby changing the water outlet mode. In other embodiments, the water distribution body 10 and the water outlet 20 can also adopt other commonly used switching structures. These switching structures are widely used in the art, and those skilled in the art can flexibly choose according to their needs.

[0044] In addition, in this embodiment, an outer shell 50 is also provided around the water outlet 20 and the water distribution body 10, which can play a protective role and is also more aesthetically pleasing.

[0045] Aerators are typically used vertically, with the inlet of the water distribution body 10 facing upwards and connected to a water source such as a faucet. The first outlet 223 and the second outlet 253 of the water outlet body 20 also typically face downwards. The internal water flow generally flows from top to bottom. The upward and downward directions in this utility model are based on this conventional arrangement of the aerator and are only for ease of description and understanding. They should not be construed as limitations on this utility model. Those skilled in the art will understand that the aerator can also be used at an angle or horizontally in application.

[0046] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0047] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
