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] In existing aerators, the water passage of the outlet body is mainly used to switch water flow in conjunction with the jet orifice. Different water outlet modes require different water passages, which are often arranged in a ring-like alternation. Due to the limited size and arrangement space of the outlet body, coupled with certain pressure boosting requirements, the water passages are often narrow. When the incoming water flow is large or turbulent (e.g., when the faucet is just turned on), backflow problems are likely to occur, causing water to overflow into the non-water passage area of the outlet body or into other water passages when it is not in use. Water overflowing into the non-water passage area will flow out from other non-outlet positions of the aerator with gaps, while water overflowing into other non-water passages will flow out from the outlets corresponding to these water passages. Either way, it will seriously affect the 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 water outlet and aerator that help reduce backflow.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0006] A water outlet body includes a main body, wherein a first water passage and a first drainage chamber are provided inside the main body, and a first water outlet is provided on the main body; the first water passage, the first drainage chamber and the first water outlet are sequentially connected from top to bottom;
[0007] The vertical length of the first water passage is less than or equal to half the vertical length of the first drainage chamber.
[0008] Preferably, the sidewall of the first drainage chamber has an impact zone, and the water outlet direction of the first water passage is directly opposite the impact zone.
[0009] Preferably, the impact zone is located in the middle of the vertical direction of the sidewall of the first drainage cavity.
[0010] 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.
[0011] Preferably, the tilt angle of the first guide surface relative to the horizontal plane is 45 to 75 degrees.
[0012] Preferably, the main body of the water outlet is further provided with a second water passage and a second drainage chamber, and the main body of the water outlet is provided with a second water outlet. The second water passage, the second drainage chamber and the second water outlet are connected sequentially from top to bottom. The first drainage chamber is arranged in a ring around the second drainage chamber and is separated from the second drainage chamber by a retaining ring.
[0013] Preferably, the impact zone is located on the inner wall of the outer side of the first drainage cavity.
[0014] Preferably, there are multiple first water passages arranged in a ring shape, and the number of impact zones is the same as the number of first water passages and corresponds one-to-one.
[0015] 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.
[0016] This utility model also provides an aerator, including the aforementioned water outlet.
[0017] The beneficial effects of this invention are as follows: The water outlet in this invention shortens the length of the first water passage by setting its vertical length to be less than or equal to half the vertical length of the first drainage chamber. This allows water to quickly pass through the narrower first water passage and enter the first drainage chamber. The first drainage chamber typically has a wider water passage / storage surface than the first water passage, making it less prone to blockage due to the flow restriction of the first water passage. This effectively improves the smoothness of water flow, reduces backflow problems, and consequently helps reduce overflow and leakage. The aerator in this invention, by employing the water outlet of this invention, also possesses the aforementioned advantages. Attached Figure Description

Detailed Implementation
[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0030] Reference Figures 1 to 5 In a preferred embodiment of the water outlet body of this utility model, a water outlet body 10 is provided, a first water passage 111 and a first drainage chamber 112 are provided inside the water outlet body 10, and a first water outlet 113 is provided on the water outlet body 10; the first water passage 111, the first drainage chamber 112 and the first water outlet 113 are connected sequentially from top to bottom; the vertical length h1 of the first water passage 111 is less than or equal to half of the vertical length h2 of the first drainage chamber 112 (i.e., h1≤h2 / 2). In this invention, the water outlet body shortens the length of the first water passage 111 by setting its vertical length to be less than or equal to half the vertical length of the first drainage chamber 112. This allows water to pass through the narrower first water passage 111 and enter the first drainage chamber 112 as quickly as possible. The first drainage chamber 112 typically has a wider water passage / storage area than the first water passage 111, making it less likely for the water to be blocked due to the flow restriction of the first water passage 111. This effectively improves the smoothness of the water flow, reduces the occurrence of backflow problems, and consequently helps to reduce overflow and leakage problems.
[0031] As a preferred embodiment of the water outlet body in this utility model, it may also have the following additional technical features:
[0032] Reference Figure 1 , Figure 2 and Figure 5 In this embodiment, the side wall of the first drainage chamber 112 has an impact area 121, and the water outlet direction of the first water passage 111 is directly opposite to the impact area 121. The water flow entering the first drainage chamber 112 through the first water passage 111 can collide with the impact area 121 on the side wall of the first drainage chamber 112 to slow down the flow rate and disperse the water flow, which can effectively improve the uniformity of the water flow and make the water flow discharged through the first outlet 113 more uniform.
[0033] In this embodiment, the impact zone 121 is located in the middle of the vertical direction of the side wall of the first drainage chamber 112, which can provide sufficient space for the water flow to impact and disperse, and help improve the uniformity of the water flow. In other embodiments, the impact zone 121 can also be selected to be located in the upper or lower part of the side wall of the first drainage chamber 112.
[0034] In this embodiment, the inner side of the lower section of the first water passage 111 away from the impact zone 121 is an inclined first guide surface 122. The extended surface of the first guide surface 122 intersects with the impact zone 121, which can guide the water flow to the impact zone 121. The structure is simple and easy to form. In other embodiments, the first water passage 111 can also be inclined as a whole, or the direction of the water flow can be adjusted by setting an inclined guide tube at the outlet end of the first water passage 111 so that the water flow can hit the impact zone 121.
[0035] The inclination angle α of the first guide surface 122 relative to the horizontal plane is 45-75 degrees. This relatively small inclination angle can effectively balance the impact and dispersion effect of water flow with the smooth flow of water within the first water passage 111, reducing resistance to the water flow entering the first water passage 111 and minimizing backflow problems. In this embodiment, the inclination angle of the first guide surface 122 relative to the horizontal plane is 68 degrees, which is more suitable for the size and internal structure of conventional water outlets and provides less resistance to water flow. In other embodiments, the inclination angle of the first guide surface 122 can be adjusted according to actual conditions and needs.
[0036] Reference Figures 1 to 5 In this embodiment, the main body 10 of the water outlet is also provided with a second water passage 131 and a second drainage chamber 132. The main body 10 of the water outlet is provided with a second water outlet 133. The second water passage 131, the second drainage chamber 132 and the second water outlet 133 are connected sequentially from top to bottom. The first drainage chamber 112 is arranged in a ring around the second drainage chamber 132 and is separated from the second drainage chamber 132 by a retaining ring. In this way, by switching the first water passage 111 and the second water passage 131, different water outlet modes can be achieved. Compared with the second drainage chamber 132, which occupies more space in the main body 10 of the water outlet, the annular first drainage chamber 112 has a narrower lateral width and is more prone to backflow problems. Therefore, the vertical length h1 of the first water passage 111 is set to be less than or equal to half of the vertical length h2 of the first drainage chamber 112, which can more effectively reduce the probability of backflow. Of course, in other embodiments, the main body 10 of the water outlet can also be selected with other suitable structures. For example, it can only have a first drainage channel, a first drainage chamber 112 and a first water outlet 113, or it can add another drainage channel, drainage chamber and drainage outlet to form more water outlet patterns; the first water passage channel 111 can also be selected with other suitable shapes, and its position can be flexibly adjusted as needed, and is not limited to this.
[0037] In this embodiment, the impact zone 121 is located on the inner wall of the outer side of the first drainage chamber 112, which facilitates the placement of the first water passage 111 in the center of the water outlet body 10, and facilitates the arrangement of the water inlet and water distribution body 20 structures. In other embodiments, the impact zone 121 may also be located on the inner wall of the inner side of the first drainage chamber 112, or when the first drainage chamber 112 has other shapes, the impact zone 121 may also be located on the inner wall of the first drainage chamber 112 in other directions, and is not limited to these.
[0038] In this embodiment, there are multiple first water passages 111 arranged in a ring. The number of impact zones 121 is the same as the number of first water passages 111 and corresponds one-to-one. This ensures that the water flow in each first water passage 111 is independent and unlikely to interfere with each other. The shape and orientation of each first water passage 111 are also easily standardized, facilitating molding. In other embodiments, multiple first water passages 111 may simultaneously correspond to one impact zone 121; those skilled in the art can adjust this flexibly as needed.
[0039] Reference Figure 3 and Figure 4 In this embodiment, there are multiple second water passages 131, all of which are connected to the second drainage chamber 132. The water outflow trajectory of each second water passage 131 intersects at a converging point 141 in the second drainage chamber 132. The converging point 141 is located at a distance above the second water outlet 133. In this way, the water flow entering the second drainage chamber 132 from the second water passage 131 can collide and disperse with each other, which can effectively improve the water flow uniformity of the second water outlet 133. The structure is also simpler and easier to form.
[0040] In this embodiment, the inner wall of the lower section of the second water passage 131, on the side away from the collecting position 141, is an inclined second guide surface 142. The extended surface of the second guide surface 142 passes through the collecting position 141, thereby guiding the water flow so that the water flow can flow and impact towards the collecting position 141. The structure is simple, easy to form, and also convenient for the arrangement of the second water passage 131. In other embodiments, the second water passage 131 can also be inclined as a whole, or a guide pipe, guide nozzle, etc. can be provided at the outlet end of the second water passage 131 to guide the water flow.
[0041] Reference Figures 1 to 5 In this embodiment, both the first outlet 113 and the second outlet 133 adopt the structure of a flow straightening hole. The first outlet 113 has a tapered or inclined columnar hole, while the second outlet 133 has a hole shape defined by a grid structure that is mainly hexagonal, which can straighten the water flow. In other embodiments, the shapes of the first outlet 113 and the second outlet 133 can also be flexibly adjusted as needed.
[0042] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.
[0043] Reference Figure 1 and Figure 2 The preferred embodiment of the aerator in this utility model includes the above-mentioned water outlet, which can effectively improve the smoothness of water flow, reduce the occurrence of backflow problems, and correspondingly help reduce overflow and leakage problems.
[0044] In this embodiment, the aerator also includes a water distribution body 20, which has a main water inlet 21 for connecting to a water source such as a faucet. The water distribution body 20 is provided with a plurality of jet holes 22, which are connected to the main water inlet 21. The water distribution body 20 is rotatably connected to the water outlet body. The inlet of the first water passage 111 and the inlet of the second water passage 131 are alternately distributed around the central axis of the water outlet body. Therefore, by rotating the water distribution body 20 and the water outlet body relative to each other, the relative positions of the jet holes 22 can be switched, so that the jet trajectory of the jet holes 22 is aligned with the first water passage 111 or the second water passage 131, thereby switching the water outlet mode of the aerator.
[0045] In addition, in this embodiment, the water distribution body 20 and the water outlet body are covered with an outer shell 30, which can provide protection and is also more aesthetically pleasing.
[0046] In other embodiments, the aerator may also adopt other suitable water distribution bodies 20, or may adopt other suitable structural configurations. For example, the water outlet body in this utility model may be connected to a water source as the aerator. Those skilled in the art can flexibly adjust the application as needed.
[0047] Aerators are typically used vertically, with the inlet of the water distribution body 20 facing upwards and connected to a water source such as a faucet. The first outlet 113 and the second outlet 133 of the main body 10 of the water outlet body also typically face downwards. The water flow inside the aerator generally flows from top to bottom. The directions such as up, down, horizontal, and vertical 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.
[0048] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.
[0049] 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.
