Abstract
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 the inner and outer water inlets to produce different water flow modes. The water distribution body has jet channels. The relative movement of the water distribution body and the water outlet body allows the jet channels to be switched to connect with different water passages, thus achieving the switching of water flow modes.
[0003] To facilitate the switching of water passages, the jet channel and the water passage are typically connected only by alignment and contact. Therefore, gaps inevitably remain between them. To further facilitate the relative movement of the water distribution body and the outlet body and reduce the friction that must be overcome during the switching of water passages, the sealing structure between them can be eliminated. Under smooth water flow, even without the sealing structure, these gaps generally do not easily leak. However, this can occur in situations where the drainage chamber is narrow or the total outlet area is much smaller than the total outlet area of the jet channel. In cases where the water flow is large or unstable, such as when the tap is just turned on, backflow can easily occur. Backflowing water can easily overflow from the gap between the jet channel and the corresponding water passage into the non-water passage area inside the aerator or overflow into other non-water passages. Water overflowing into the non-water passage area will flow out from other non-outlet positions with gaps in the aerator, while water overflowing into other non-water passages will flow out from the corresponding outlets of these passages. Either way, it will seriously affect the user experience. Utility Model Content

The first water passage, the first drainage chamber and the first water outlet are connected in sequence, and the second water passage, the second drainage chamber and the second water outlet are connected in sequence. The lateral inner width of the first drainage chamber is smaller than the lateral inner width of the second drainage chamber.
[0015] Preferably, the first drainage cavity is annular and surrounds the second drainage cavity.
[0016] Preferably, the vertical length of the first water passage is less than or equal to half the vertical length of the first drainage chamber.
[0017] Preferably, the first drainage chamber has an impact zone in the middle of its sidewall in the vertical direction, and the water outlet direction of the first water passage is towards the impact zone.
[0018] Preferably, the inner side of the lower section of the first water passage away from the impact zone is an inclined first guide surface, and the extended surface of the first guide surface intersects with the impact zone; the inclination angle of the first guide surface relative to the horizontal plane is 45 to 75 degrees.
[0019] Preferably, there are multiple second water passages, all of which are connected to the second drainage chamber. The water outflow trajectories of each second water passage intersect at a converging point within the second drainage chamber, and the converging point is located at a distance above the second water outlet.

When backflow occurs in the first water passage channel, the backflowing water overflows through the first overflow port into the overflow trough and is collected there, preventing overflowing water from flowing into the non-water-passing area inside the aerator or into the non-water-passing second water passage channel. When the water flow in the first water passage channel returns to normal, the water collected in the overflow trough can be discharged through the first water passage channel or by other means, effectively reducing leakage caused by backflow and thus significantly improving the user experience. The aerator of this utility model, by employing the water outlet body of this utility model, also possesses the aforementioned advantages. Attached Figure Description

[0039] Reference Figures 1 to 5 A preferred embodiment of the water outlet body in this utility model includes a water outlet body 10. The water outlet body 10 is provided with a first water passage 111 and a second water passage 121. The first water passage 111 has a first water inlet 112, and the second water passage 121 has a second water inlet 122. An overflow trough 13 is provided in the water outlet body 10. The first water inlet 112 and the second water inlet 122 are both located above the bottom surface of the overflow trough 13. A first overflow port 113 is provided on the side wall of the first water passage 111. The first water passage 111 is connected to the overflow trough 13 through the first overflow port 113. The first water inlet 112 is higher than the bottom surface of the first overflow port 113. The water outlet of this invention features an overflow trough 13, with the first water passage 111 connected to the overflow trough 13 via the first overflow port 113 on its side wall. The first inlet 112 and the second inlet 122 are both located above the bottom surface of the overflow trough 13, with the first inlet 112 higher than the bottom surface of the first overflow port 113. Under normal circumstances, water can flow through the first water passage 111 without entering the first overflow port 113. When backflow occurs in the first water passage 111, the backflowing water overflows through the first overflow port 113 into the overflow trough 13 and is collected there. This prevents overflowing water from flowing into the non-water-passing area inside the aerator or into the non-water-passing second water passage 121. When the water flow in the first water passage 111 returns to normal, the water collected in the overflow trough 13 can be discharged through the first water passage 111 or by other means, effectively reducing leakage caused by backflow and thus improving the user experience.
[0040] As a preferred embodiment of the water outlet body in this utility model, it may also have the following additional technical features:
[0041] In this embodiment, the bottom surface of the first overflow port 113 is flush with the bottom surface of the overflow tank 13. Thus, in the event of backflow, after water remains in the overflow tank 13, when the water flow in the first water passage 111 returns to normal, the water in the overflow tank 13 can flow back from the first overflow port 113 to the first water passage 111 and be discharged. At the same time, the negative pressure generated by the water flow can also promote the backflow of water. This can effectively prevent water from remaining in the overflow tank 13 for a long time and thus prevent bacteria from growing. There is no need to add additional structures or operations to drain the water remaining in the overflow tank 13, making it convenient to use. In other embodiments, the bottom surface of the first overflow port 113 may be higher than the bottom surface of the overflow tank 13. The water in the overflow tank 13 may be discharged through the second water passage 121 or by setting a drain outlet connected to the overflow tank 13 outside the water outlet. For some aerators that can be flipped, a drain channel connected to the overflow tank 13 may be set. For example, the inlet of the drain channel may be set above the overflow tank 13 and the outlet may be set at the top of the aerator. After normal use, the water remaining in the overflow tank 13 may be discharged from the drain channel by flipping or tilting the aerator. Those skilled in the art can choose flexibly as needed.
[0042] In this embodiment, the bottom surface of the first overflow port 113 slopes downward from the overflow tank 13 towards the first water passage 111, which facilitates the return flow of water retained in the overflow tank 13 to the first water passage 111. In other embodiments, the bottom surface of the first overflow port 113 may also be set as a horizontal plane.
[0043] In this embodiment, a second overflow port 123 is provided on the side wall of the second water passage 121. The second water passage 121 is connected to the overflow tank 13 through the second overflow port 123. The second overflow port 123 allows the overflow tank 13 to collect and retain the water overflowing from the second water passage 121 when backflow occurs, further reducing leakage caused by backflow. On the other hand, it also allows the water retained in the overflow tank 13 to be discharged from the second water passage 121.
[0044] In some embodiments, the bottom surface of the second overflow port 123 is higher than the bottom surface of the first overflow port 113. This prevents overflow water from entering the second water passage 121 from the second overflow port 123 and causing leakage when the backflow in the first water passage 111 is minor and the backflow water is small. When the backflow in the first water passage 111 is severe, the water remaining in the overflow tank 13 can flow from the second overflow port 123 to the second water passage 121 and be discharged after exceeding a certain amount, thus preventing backflow water from overflowing into the non-water passage area of the aerator and helping to reduce the failure rate.
[0045] In this embodiment, the bottom surfaces of the first overflow port 113 and the second overflow port 123 are flush with the bottom surface of the overflow trough 13. Therefore, when backflow occurs in the first water passage 111 and a small amount of water remains in the overflow trough 13, after switching to the second water passage 121, the water in the overflow trough 13 can also be discharged from the second overflow port 123 into the second water passage 121 through natural water flow or negative pressure generated by the water flow. This helps to promptly drain the accumulated water in the overflow trough 13, allowing the aerator to promptly drain accumulated water in both the first and second water passage 111 water outlet modes, preventing prolonged water retention and bacterial growth, thus improving hygiene. However, in this case, if backflow occurs in the first water passage 111 and the backflow volume is large, there is a certain probability that the backflow water will enter the non-flowing second water passage 121 from the second overflow port 123, causing leakage and affecting the user experience. Therefore, this method is generally applicable to scenarios with minor backflow.
[0046] In this embodiment, the first water inlet 112 is located at the top of the first water passage 111, and the second water inlet 122 is located at the top of the second water passage 121. The first water inlet 112 and the second water inlet 122 are adjacent and flush, which facilitates the aerator to switch the water supply path and thus switch the water outlet mode. In other embodiments, the first water inlet 112 and the second water inlet 122 may also be selected to be set in other suitable positions such as the side wall of the first water passage 111 and the side wall of the second water passage 121, and are not limited thereto.
[0047] In this embodiment, the main body 10 of the water outlet is provided with a first drainage chamber 114 and a second drainage chamber 124, and the main body 10 of the water outlet is provided with a first outlet 115 and a second outlet 125. The first water passage 111, the first drainage chamber 114 and the first outlet 115 are connected in sequence, and the second water passage 121, the second drainage chamber 124 and the second outlet 125 are connected in sequence. The lateral inner width of the first drainage chamber 114 is smaller than that of the second drainage chamber 124. Therefore, the first water passage 111 and the first drainage chamber 114 are more prone to backflow than the second water passage 121 and the second drainage chamber 124. It is also more suitable to set a first overflow port 113 to allow the backflow water of the first water passage 111 to be retained in the overflow trough 13.
[0048] In this embodiment, the first drain chamber 114 is annular and surrounds the second drain chamber 124, which conforms to the arrangement of most aerators. In this arrangement, the first drain chamber 114 is also relatively narrow in all parts, and the first water passage 111 is more prone to backflow, making it more suitable for arranging the first overflow port 113. In other embodiments, the arrangement of the first drain chamber 114 and the second drain chamber 124 can also be flexibly adjusted as needed. For example, a left-right or staggered arrangement can be used. Of course, the lateral inner width of the first drain chamber 114 can also be set to be greater than the lateral inner width of the second drain chamber 124 to make the water flow in the first drain chamber 114 smoother. However, after long-term use, scale and impurities will also accumulate at the first outlet 115, which will lead to a decrease in water flow or blockage, and the probability of backflow will also increase. Those skilled in the art can flexibly select and adjust as needed, and are not limited to this.
[0049] In this embodiment, the vertical length h1 of the first water passage 111 is less than or equal to half the vertical length h2 of the first drainage chamber 114. Due to the size of the water outlet and the arrangement requirements of the first water passage 111 and the second water passage 121, the water passage area of the first water passage 111 is usually narrow, while the first drainage chamber 114 has a relatively wide water passage / storage area because it is connected in the overall circumference of the water outlet body 10. This size design in this embodiment allows the water to pass through the first water passage 111 more quickly, which helps to reduce the probability of water backflow.
[0050] Reference Figures 1 to 3 In this embodiment, the first drainage chamber 114 has an impact zone 14 at the middle of its sidewall in the vertical direction. The water outlet direction of the first water passage 111 faces the impact zone 14. In this way, the water discharged from the first drainage chamber 114 can first collide with the impact zone 14 in the middle of the sidewall of the first drainage chamber 114 and be dispersed, and then be discharged from the first outlet 115. This helps to improve the uniformity of the water discharged from the first outlet 115. Furthermore, since the angle of inclination of the first water passage 111 relative to the vertical direction is larger, the resistance to water flow is greater, and the probability of backflow will increase accordingly. The smaller the angle of inclination of the first water passage 111 relative to the vertical direction, the lower the impact point between the water flow and the side wall of the first drainage chamber 114 will be. When the water flow is small, it is easier for the water to sag during the outflow process, thus reducing the impact with the side wall of the first drainage chamber 114. In this embodiment, the impact area 14 is set in the middle of the side wall of the first drainage chamber 114, which can better balance the smoothness of the water flow in the first water passage 111 and the degree of dispersion of the impact between the water flow and the side wall of the first drainage chamber 114, that is, it can better balance the backflow probability and the uniformity of water output. In other embodiments, the impact area 14 can also be set in the upper or lower part of the side wall of the first drainage chamber 114, which can be flexibly adjusted by those skilled in the art as needed.
[0051] The inner side of the lower section of the first water passage 111, away from the impact zone 14, is an inclined first guide surface 15. The extended surface of the first guide surface 15 intersects with the impact zone 14. The inclination angle α of the first guide surface 15 relative to the horizontal plane is preferably 45 to 75 degrees, which is smaller than the inclination angle in the vertical direction. Correspondingly, it has less obstruction to the water flow, reducing the probability of backflow, and does not excessively increase the restriction on the arrangement position of the first water passage 111 and the first inlet 112. In this embodiment, the inclination angle α of the first guide surface 15 relative to the horizontal plane is 68 degrees, that is, the inclination angle relative to the vertical direction is 22 degrees, which is more suitable for the arrangement of water outlets of commonly used sizes and is also easy to form. In other embodiments, this angle can also be adjusted as needed. The guidance of the water outlet direction of the first water passage 111 can also be achieved by tilting the first water passage 111 as a whole, or by setting a guide pipe at the water outlet end of the first water passage 111, etc., and is not limited to these methods.
[0052] Reference Figures 3 to 5 In this embodiment, there are multiple second water passages 121, all of which are connected to the second drainage chamber 124. The water outflow trajectory of each second water passage 121 intersects at a converging point 16 in the second drainage chamber 124. The converging point 16 is located at a distance above the second water outlet 125. In this way, the water flow of each second water passage 121 can collide with each other and be dispersed at the converging point 16 at a distance above the second water outlet 125, which can effectively improve the uniformity of water outflow from the second water outlet 125.
[0053] In this embodiment, the collecting position 16 is located at the lateral center of the second drainage chamber 124, which helps to further improve the uniformity of water discharge from the second outlet 125. In other embodiments, the position of the collecting position 16 can also be flexibly adjusted as needed. In this embodiment, the inner sidewall of the lower section of the second water passage 121 away from the collecting position 16 is an inclined second guide surface 17. The extension line of the second guide surface 17 intersects with the collecting position 16, which can guide the water flow of the second water passage 121. The structure is simple and easy to form. Similarly, in other embodiments, the water discharge trajectory of the second water passage 121 can also be adjusted by tilting the second water passage 121 as a whole, or by setting a guide pipe at the outlet end of the second water passage 121.
[0054] In addition, in this embodiment, the upper section of the first water passage 111 and the upper section of the second water passage 121 are both perpendicular to the horizontal plane, which facilitates the water distribution body 20 to deliver water to both and also helps to reduce the probability of backflow.
[0055] In this embodiment, a water outlet plate 18 is provided at the bottom of the main body 10. A blocking portion 181 is located on the water outlet plate 18 directly below the collecting position 16. The second water outlet 125 is located in the area outside the blocking portion 181 on the water outlet plate 18. This way, after the water flows from each of the second water passages 121 collide with each other, the portion of water that loses lateral kinetic energy can collide with the blocking portion 181 and disperse, instead of flowing directly out of the second water outlet 125, which helps to further improve the uniformity of the water flow. In this embodiment, both the first water outlet 115 and the second water outlet 125 are flow straightening holes. The first water outlet 115 has a tapered or inclined columnar hole, while the second water outlet 125 has a hole shape defined by a primarily hexagonal grid structure. In other embodiments, the shape and distribution of the first water outlet 115 and the second water outlet 125 can also be adjusted.
[0056] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.
[0057] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7 This utility model also provides an aerator, including a water distribution body 20 and the aforementioned water outlet body. The water distribution body 20 can switch the water passage and thus switch the water outlet mode. Since this aerator uses the water outlet body of this utility model, it can also effectively reduce leakage caused by backflow and effectively improve the user experience.
[0058] As a preferred embodiment of the aerator in this utility model, it may also have the following additional technical features:
[0059] In this embodiment, the water distribution body 20 and the water outlet body are rotatably connected. One of the water distribution body 20 and the water outlet body 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 bearing surface 33 corresponding to the pressing part 31. The elastic part 32 presses the pressing part 31 against the bearing surface 33. The friction between the pressing part 31 and the bearing surface 33 can limit the relative rotation of the water distribution body 20 and the water outlet body, thereby preventing the water outlet body and the water distribution body 20 from accidentally switching the water outlet mode due to accidental relative rotation after being subjected to water flow reaction force, negative pressure force, or user bump. Furthermore, after long-term use and wear, the elasticity of the elastic part 32 can also maintain the pressing of the pressing part 31 against the bearing surface 33, making it more reliable and durable.
[0060] In this embodiment, the pressure-bearing part 31 and the elastic part 32 are provided on the water outlet body, and the pressure-bearing surface 33 is provided on the water distribution body 20. That is, the water outlet body is the first component and the water distribution body 20 is the second component. In other embodiments, the two can be interchanged.
[0061] Reference Figures 1 to 5 In this embodiment, a connecting hole 19 is provided in the water outlet body, and a plurality of elastic hooks 21 are correspondingly provided on the water distribution body 20. These hooks 21 are hooked on the lower surface of the connecting hole 19, thereby rotatably connecting the water distribution body 20 and the water outlet body. In other embodiments, the water outlet body and the water distribution body 20 can also adopt other commonly used rotatable connection structures. For example, an annular groove can be provided on one of the water distribution body 20 and the water outlet body, 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.
[0062] Reference Figure 6 and Figure 7 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 process and 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.
[0063] 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 boss may 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.
[0064] 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 and the elastic part 32 can be integrally molded with the first component or parts of the first component through 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 thereto.
[0065] 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.
[0066] 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 20 is used as the pressure-bearing surface 33, and the cantilever is also positioned on the outer side of the water outlet body. Both are arc-shaped, ensuring contact during relative rotation of the water distributor 20 and the water outlet body 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 20 or the water outlet body 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 20 or the water outlet body, for example, on the interlocking structure of the two. Those skilled in the art can flexibly select and adjust as needed.
[0067] In this embodiment, a first positioning protrusion 41 is provided on the water distribution body 20, and a second positioning protrusion 42 is provided on the water outlet body. The first positioning protrusion 41 can abut against the second positioning protrusion 42 as the water distribution body 20 and the water outlet body rotate relative to each other, thereby restricting the rotation of the water distribution body 20 and the water outlet body. This allows for positioning of the relative angle between the water distribution body 20 and the water outlet body, facilitating the user to switch water outlet modes. In this embodiment, there are two second positioning protrusions 42 on the water outlet body, and the first positioning module of the water distribution body 20 is located between the two second positioning protrusions 42, 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.
[0068] Reference Figure 2 and Figure 5 In this embodiment, the water distributor 20 has a main inlet end 22 for connecting to a water source such as a faucet. Multiple jet holes 23 are provided within the water distributor 20, communicating with the main inlet end 22. The water distributor 20 is rotatably connected to the water outlet. The inlets of the first water passage 111 and the second water passage 121 are alternately distributed around the central axis of the water outlet. Therefore, by rotating the water distributor 20 and the water outlet relative to each other, the relative positions of the jet holes 23 can be switched, aligning the jet trajectory of the jet holes 23 with either the first water passage 111 or the second water passage 121, thereby switching the water outlet mode of the aerator. In other embodiments, the aerator may also employ other suitable water distributors 20, or other suitable structural configurations. For example, the water outlet in this invention may simply be connected to a water source to serve as the aerator. Those skilled in the art can flexibly adjust the application as needed.
[0069] Reference Figures 1 to 5 In addition, in this embodiment, the water outlet and the water distribution body 20 are also covered with an outer shell 50, which can play a protective role and is also more aesthetically pleasing.
[0070] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.
[0071] Aerators are typically used vertically, with the inlet of their water distribution body 20 facing upwards and connected to a water source such as a faucet. The first outlet 115 and the second outlet 125 of their water outlet body also typically face downwards. The internal water flow generally flows from top to bottom. The upward, downward, and horizontal 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.
[0072] 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.
