Description

TECHNICAL FIELD

[0001] The utility model relates to the bathroom technical field. More specifically, the utility model relates to a faucet immediately stop device. BACKGROUND

[0002] In modern home life and commercial places, as a water terminal device, the performance of the faucet directly affects the user experience and water resource utilization efficiency. With the improvement of people's living quality and the enhancement of water resource conservation awareness, the functional requirements for the faucet are increasingly stringent, and the immediately stop function becomes one of the key indicators for measuring the quality of the faucet.

[0003] After the traditional faucet is closed, there is often a phenomenon that water droplets slowly seep out of the water outlet nozzle, which not only causes waste of water resources, but also causes the use environment to be wet, breeds bacteria, and affects the sanitary condition. For example, in a family kitchen, the residual water droplets after the faucet is closed will drip into the sink, and long-term accumulation will cause water stains around the sink, corrode the surface of the sink, and affect the appearance and service life; in a public bathroom, this phenomenon will make the floor slippery, increasing the risk of users slipping and falling.

[0004] The existing immediately stop faucet solution has many drawbacks. Some designs rely on complex electronic induction devices or mechanical structures, which are costly, increasing the purchase cost of consumers and the production cost and technical threshold of production enterprises, limiting the popularization and promotion of products. Complex structure also reduces product stability and causes frequent failures. Once a problem occurs, it is difficult and expensive to repair. For example, some electronic induction type immediately stop faucets are easily affected by environmental electromagnetic interference, causing misjudgment and preventing the faucet from closing or opening normally; products with complex mechanical structures have many parts, which are prone to wear and tear during frequent opening and closing, affecting the realization of the immediately stop function.

[0005] In addition, the existing immediately stop technology application scenarios are relatively limited, mostly only applicable to specific types of faucets, difficult to promote to other bathroom products, and unable to meet the diversified needs of the entire bathroom market.

[0032] The utility model makes further detailed description in combination with the drawings, so that the person skilled in the art can implement according to the description.

[0033] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0034] It should be noted that in the description of the utility model, the orientation or positional relationship indicated by the terms "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0035] It should be noted that the control method in the following technical solution is a conventional method unless otherwise specified, and the device structure can be obtained from commercial channels unless otherwise specified.

[0036] As Figures 1-7 The utility model provides a faucet is closed and is stopped device, include:

[0037] Flexible gasket 1 is convex structure, and the top of convex structure is equipped with closable cutout 100, and both ends of convex structure extend outward to form sealing end face, and the thickness of the top of convex structure is less than the thickness of both sides, and the top of convex structure is set to the direction of water outlet of faucet.

[0038] In the above technical scheme, flexible gasket 1 is made of high-quality rubber, and the rubber has good elasticity, aging resistance and sealing performance, can ensure that the elastic reset characteristic of flexible gasket 1 is stable during long-term frequent use, and reliably realizes the closure and opening of cutout 100, maintains the function of closing and stopping immediately, and is not easy to be damaged due to water and daily use environment, guarantees the service life of the device.

[0039] Flexible gasket 1 processing: flexible gasket 1 is made by using mold injection molding process. In the mold design, the shape and size of the protruding structure are accurately set, the accuracy of the top notch is ensured, the notch can be tightly fitted when closed, and water leakage is prevented; control the thickness difference between the top and the two sides to ensure smooth water flow when opening the faucet and not to block the aerator. After injection molding, the gasket is subjected to quality inspection, and products with defects such as bubbles and size deviation are removed.

[0040] Device assembly:

[0041] Place the processed flexible gasket 1 between the water outlet nozzle connector 4 and the aerator in the internal water channel 3 of the faucet at the elbow pipe 2 of the faucet, so that the sealing end faces at both ends of the flexible gasket 1 are tightly fitted with the water outlet nozzle connector plane and the aerator plane respectively, and the sealing is ensured.

[0042] Install the assembled water outlet nozzle connector with flexible gasket 1 and aerator assembly to the water outlet end of the faucet body through threaded connection or other suitable fixing method, ensure firm connection, prevent loosening during use and cause water leakage. The installation position is shown in Figure 5 .

[0043] Working process

[0044] Open the faucet: as shown in Figure 3 , 4 and 6, when the faucet handle is opened, the water flows into the internal pipe of the faucet, and the water pressure acts on the flexible gasket 1. Because the top of the flexible gasket 1 is provided with a closable notch 100, and the thickness of the top is less than that of the two sides, under the water pressure, the notch 100 is automatically opened, the water flows through the notch 100, and then flows out of the faucet after passing through the aerator. At the same time, due to the special protruding structure of the flexible gasket 1, only the top deforms under the action of water pressure, which will not block the aerator, ensuring normal water flow and water outlet effect.

[0045] Close the faucet: as shown in Figure 1 , 2 and 7, after closing the faucet handle, the water pressure in the pipe decreases rapidly to near 0. At this time, the flexible gasket 1 automatically resets due to the elastic properties of rubber, and the notch 100 at the top automatically closes. The closed notch 100 is tightly fitted, effectively isolating the residual water in the internal pipe of the faucet, so that it cannot seep out, thereby realizing the function of stopping immediately after closing, avoiding the occurrence of dripping phenomenon after closing the traditional faucet.

[0046] In another technical solution, the sealing end face includes a first end face 110 and a second end face 120, the first end face 110 cooperates with the water outlet nozzle connector 4 of the faucet, and the second end face 120 cooperates with the aerator of the faucet.

[0047] In the above technical solution, as shown in Figure 1 ,2 As shown in Figure 5, when installing the flexible gasket 1, first accurately place the first end face of the flexible gasket 1 on the mating plane of the outlet connector, and gently press it to ensure full contact. Due to the flexibility of the rubber flexible gasket 1, it can automatically adapt to minor unevenness of the plane, achieving a good initial seal. Carefully insert the aerator inner tank 6 into the aerator outer shell 5, ensuring that the filter screens and turbulence plates of the aerator inner tank 6 are correctly positioned and not misaligned or damaged. During the insertion process, a small amount of food-grade lubricating oil can be applied to facilitate the smooth installation of the aerator inner tank 6. Align the aerator outer shell 5, with the aerator inner tank 6 installed, with the second end face 120 of the flexible gasket 1, so that the annular groove on the inner wall of the aerator outer shell 5 precisely aligns with the second end face 120. Then, slowly rotate the aerator outer shell 5 to connect it to the outlet connector 4 via threads and tighten it. During the tightening process, constantly observe the state of the flexible gasket 1 to ensure that it is not twisted or displaced until the aerator housing 5 and the outlet connector 4 are fully tightened. At this time, the second end face 120 of the flexible gasket 1 is tightly embedded in the annular groove of the aerator housing 5, completing the assembly of the entire instant shut-off device.

[0048] In another technical solution, the closable cut 100 is cross-shaped, circular, oval, or square.

[0049] In another technical solution, such as Figures 1-4 As shown, this embodiment of the invention employs a cross-shaped cut, whose special shape allows water to flow through multiple channels. When the faucet is turned on, water can flow from the four directions of the cross into the spacer below, allowing for faster passage. For scenarios requiring large volumes of water, such as quickly filling a container, the cross-shaped cut offers a significant advantage in water flow efficiency. However, under high water pressure, the water flow impacting the edges of the cross-shaped cut may generate some turbulence, affecting the uniformity of the water output.

[0050] Cross-shaped, circular, oval, or square shapes each have their own characteristics, and in practical applications, the appropriate shape can be selected based on the specific application scenario and requirements.

[0051] I. Water Flow Characteristics:

[0052] Circular cut: Water flows through evenly, and the water flows in smoothly when the faucet is turned on. It has good flowability under low water pressure and the water flow is gentle and stable. It can provide a comfortable water flow experience in daily washing and brushing scenarios and avoid water splashing.

[0053] Cross-shaped cut: It has four diversion channels, resulting in high water flow efficiency and significant advantages in scenarios with large water volume requirements (such as quickly filling a container). However, under high water pressure, the water flow impacting the edges of the cut can easily generate turbulence, affecting the uniformity of water output.

[0054] Oval cutout: Combines the characteristics of circular and cross-shaped parts, with strong water flow capacity in the long axis direction and some degree of water flow stability in the short axis direction, suitable for scenarios with specific requirements for water flow speed and stability.

[0055] Square cutout: Vortexes are easily formed at the corners when water flows through, and the overall water flow uniformity is not as good as that of circular and oval cutouts, but in specific designs, square cutouts can achieve special water flow patterns, such as concentrated water outflow in a specific direction.

[0056] Circular cutout: When closed, the circumference fits tightly, the structure is simple, and it is less affected by material elasticity and processing precision. As long as the edges are in close contact, it can reliably block water flow, seal stably, and effectively prevent water leakage.

[0057] Cross-shaped cutout: Four edges need to fit perfectly to achieve good sealing, which requires high elasticity and precision of the gasket material. The cross-shaped intersection is prone to poor sealing, but the sealing effect can still meet the requirements when the material and process meet the standards.

[0058] Oval cutout: Similar to circular cutouts, the sealing is relatively reliable, but there is a difference in sealing pressure distribution between the long and short axes, so the material's elasticity in different directions needs to be considered in the design.

[0059] Square cutout: The four corners are the key and difficulty of sealing. Special treatment (such as increasing the thickness of the sealing material or optimizing the corner structure) is needed to ensure sealing performance.

[0060] Three, durability:

[0061] Circular cutout: Stress distribution is uniform, and the circumference uniformly bears water pressure and elastic deformation during frequent opening and closing, which is less prone to local excessive wear and tear, making it durable and suitable for frequent use.

[0062] Cross-shaped cutout: The four corners repeatedly deform under water pressure, with stress concentration, which is prone to fatigue wear, causing the cutout edges to crack or deform, affecting service life, and making it relatively less durable.

[0063] Oval cutout: Stress distribution is between circular and cross-shaped cutouts, with different deformation degrees in the long and short axes, and stress concentration may occur at the ends of the short axis, but it is better than the cross-shaped cutout, making it relatively durable.

[0064] Square cutout: The corners have obvious stress concentration, and the corners are prone to damage during frequent opening and closing, making it less durable. Therefore, attention should be paid to corner wear and tear during use, and the gasket should be replaced as needed.

[0065] Four, processing difficulty and cost:

[0066] Circular cutout: simple geometry, easy to ensure precision and quality in mold design and processing, simple production process, low processing cost, obvious cost control advantage in large-scale production.

[0067] Cross-shaped cutout: high processing precision required, complex mold making and production operation, difficult to ensure shape precision and cutout quality, increasing processing cost and production difficulty.

[0068] Elliptical cutout: processing difficulty between circular and cross-shaped, need to accurately control the size and shape precision of major and minor axes, cost is in the middle range.

[0069] Square cutout: although the shape is regular, the corner processing needs special treatment to ensure precision and strength, increasing processing procedures and cost, higher processing difficulty.

[0070] Specifically, for kitchen faucets, due to the frequent task of washing tableware, there is a high requirement for water passing efficiency, and cross-shaped cutout is preferred. To solve the sealing problem, the gasket material and processing technology can be optimized. Use nitrile rubber with better sealing performance to make the gasket, and improve the mold to increase the processing precision of the cross-shaped cutout, ensure the smoothness and flatness of the cutout edge, and enhance the sealing effect. At the same time, during the daily maintenance of the faucet, the gasket should be checked regularly, and if the cutout sealing is not tight, it should be replaced in time to ensure the use experience and water saving effect. Bathroom basin faucet: mainly used for washing, with high requirements for water flow stability and softness, circular cutout is the ideal choice. Due to its good sealing performance and durability, it can meet the daily use requirements while reducing the risk of water leakage and replacement frequency. If there is a potential risk of oil contact near the basin faucet, such as placing skin care products near the faucet, a circular cutout gasket made of nitrile rubber material can be selected to balance the sealing and oil resistance. Shower faucet: considering the need for water flow uniformity and stability during use, elliptical cutout is more suitable. It can ensure a certain water passing efficiency and maintain water flow stability. In terms of material selection, if the shower water temperature is high, silicone rubber gasket has advantages, its heat resistance can ensure stable performance under hot water washing, prolong the service life of the gasket, and ensure the comfort of shower.

[0071] In another technical scheme, the flexible gasket 1 is a silicone rubber gasket or a nitrile rubber gasket.

[0072] In the above technical scheme, silicone rubber gasket and nitrile rubber gasket have unique performance in faucet on-off device, and the application scene is different. Silicone rubber gasket performs well in heat resistance, aging resistance and hygiene, and is suitable for environments with high requirements for these performances; nitrile rubber gasket has advantages in oil resistance and sealing performance, and is more suitable for places that may contact oil and have high sealing requirements. In actual application, the selection can be made according to the actual application scene and demand.

[0073] I. Characteristics of Silicone Rubber Gaskets:

[0074] 1)Excellent Heat Resistance: Silicone rubber has outstanding heat resistance, maintaining stable physical properties in high-temperature environments. Its operating temperature range is typically between -50°C and 250°C, and even some special formulations can withstand higher temperatures. This characteristic allows silicone rubber gaskets to maintain good elasticity and sealing performance in faucets that may be subjected to hot water, effectively extending the service life of the gasket without rapid aging, deformation, or loss of sealing effect due to high temperatures.

[0075] 2)Good Aging Resistance: In natural environments, silicone rubber has strong resistance to ozone, ultraviolet light, and weathering. Long-term exposure to air results in slow performance changes and a low likelihood of cracking, hardening, and other aging phenomena. This means that faucet shut-off devices using silicone rubber gaskets can reliably achieve the shut-off function even after long-term use and environmental erosion, reducing the risk of water leakage due to gasket aging and lowering maintenance costs.

[0076] 3)Hygienic and Environmentally Friendly: Silicone rubber is a non-toxic and harmless material that meets food hygiene and safety standards. In water faucet applications where water is frequently in contact, silicone rubber gaskets do not release harmful substances into the water, ensuring the safety and hygiene of the water. This characteristic makes it particularly suitable for use in places with high water quality requirements, such as homes, hospitals, and food processing sites.

[0077] 4)High Elasticity and Low Compression Permanent Deformation: Silicone rubber has excellent elasticity, quickly returning to its original shape after being compressed by external forces. At the same time, its compression permanent deformation rate is low, meaning that it can maintain good shape and sealing performance even after long-term compression. In faucet shut-off devices, gaskets are frequently subjected to water pressure and mechanical compression, and these characteristics of silicone rubber ensure that the gasket can tightly adhere to the faucet each time it is opened or closed, effectively preventing water leakage and maintaining stable operation of the device.

[0078] 5)Good Electrical Insulation Performance: Although electrical insulation performance is not a key factor in water faucet applications, the good electrical insulation of silicone rubber makes it suitable for some special situations (such as environments where water faucets are associated with electrical equipment), increasing its application flexibility. However, silicone rubber gaskets also have some disadvantages, such as relatively low tensile strength, poor oil resistance, and swelling when in contact with oil, which can affect sealing performance.

[0079] II. Characteristics of Nitrile Rubber Gaskets:

[0080] 1) Excellent oil resistance: Nitrile rubber has excellent resistance to oil substances, which is a significant feature that distinguishes it from silicone rubber. It can resist the corrosion of various mineral oils, lubricating oils, fuel oils, etc., and is not prone to swelling, deformation or damage in an oil environment. If the environment where the faucet is located may come into contact with oil substances, such as near the kitchen faucet where cooking oil may splash, using nitrile rubber gaskets can ensure stable performance of the gasket and maintain good sealing effect to prevent oil leakage.

[0081] 2) Good sealing performance: Nitrile rubber has high tensile strength and good wear resistance, which makes it perform well in sealing applications. It can tightly adhere to the sealing surface, effectively filling small gaps and uneven places, and preventing liquid and gas leakage. In the faucet stop-and-go device, nitrile rubber gaskets can rely on their good sealing performance to ensure that water flow is completely blocked when the faucet is turned off, achieving the function of stop-and-go and reducing water leakage.

[0082] 3) Good resistance to chemical corrosion: In addition to oil resistance, nitrile rubber also has some resistance to weak acids, weak bases and organic solvents, which makes it possible to maintain stable performance in some faucet use scenarios that may come into contact with chemical cleaners or other chemicals, extending the service life of the gasket.

[0083] 4) High cost performance: Compared with some high-performance rubber materials, nitrile rubber has relatively low cost and high cost performance. Under the premise of meeting the sealing performance requirements, using nitrile rubber gaskets can reduce the production cost of the product, which is particularly advantageous for large-scale production of faucet stop-and-go devices, helping to improve the market competitiveness of the product. However, nitrile rubber has poor cold resistance and can become hard and brittle in low-temperature environments, leading to a decrease in sealing performance. Its heat resistance is also not as good as that of silicone rubber, with a working temperature range of -20°C to 120°C, limiting its application in high-temperature environments.

[0084] In practical applications, the environment of the faucet may change over time. For example, a kitchen faucet may initially mainly contact water, but later may frequently contact oil due to kitchen renovation or changes in usage habits. In a dynamic changing environment, the change in the environment can be detected, such as by installing a sensor near the faucet to monitor in real time whether there is oil present. For example, an optical-based oil sensor can be used, and once the concentration of oil exceeds a set threshold, a signal is transmitted to the user's mobile phone APP or smart home system through Bluetooth or Wi-Fi. After receiving the reminder, the user can choose to replace the gasket according to the actual situation. If the faucet is in an environment that frequently contacts oil, replace the silicone rubber gasket with a nitrile rubber gasket; if it only occasionally contacts oil, replace it during regular maintenance or use a special protective coating to treat the silicone rubber gasket to enhance its oil resistance. Maintain a record file for each faucet, recording information such as gasket replacement time and material. Combine sensor data and usage time to predict the service life and performance changes of the gasket using algorithms, and send a replacement warning to the user in advance to ensure that the faucet is always in good working condition.

[0085] In another technical solution, the thickness of the top end of the protruding structure is 0.3-1 mm.

[0086] In the above technical solution, water pressure and water flow factors are considered: if the top of the protrusion is too thick, the difficulty of pushing the cutout open increases under water pressure, which may cause the water flow to become smaller and the water to flow poorly; if it is too thin, it is easy to deform excessively under water pressure, which may block the aerator and affect water flow, and it is easy to be damaged under frequent pressure. For the thickness of the side surface, too thin will reduce the overall structural strength and sealing performance, and too thick will increase the water flow resistance. Assuming that the water pressure in a common household is 0.1-0.3 MPa, and combining the characteristics of rubber materials, if silicone rubber is used as the material for making the flexible gasket 1, the top thickness can be close to 0.5 mm due to its good elasticity, and if nitrile rubber is used as the material for making the flexible gasket 1, although nitrile rubber also has elasticity, its elastic modulus is higher than that of silicone rubber, and its elastic recovery ability is slightly weaker. In a faucet that turns off immediately after stopping, the top thickness of the nitrile rubber gasket needs to be greater than that of the silicone rubber gasket, and the top thickness of the nitrile rubber gasket is 1 mm, which can effectively resist water pressure impact and ensure normal operation of the gasket to achieve the immediate-off function. For areas with high water pressure, the difficulty of pushing the cutout open is relatively reduced due to the high water pressure, and the top thickness of the flexible gasket 1 can be appropriately reduced, such as for a silicone rubber flexible gasket, the top thickness is reduced to 0.3 mm, and for a nitrile rubber flexible gasket, the top thickness is reduced to 0.5 mm. For areas with low water pressure, the top thickness of the flexible gasket 1 needs to be appropriately increased, such as for a silicone rubber flexible gasket, the top thickness is increased to 1 mm, and for a nitrile rubber flexible gasket, the top thickness is increased to 1.5 mm.

[0087] In another technical solution, the thickness of the two side surfaces of the convex structure is the same, and the thickness is 1-8 mm.

[0088] In the above technical solution, for the two side surfaces, if the thickness is too thin, the strength and sealing performance of the overall structure will be reduced, and if the thickness is too thick, the water flow resistance will be increased. The thickness can be selected according to actual application and demand. Assuming that the water pressure in a common household is 0.1-0.3 MPa, and considering the characteristics of the rubber material, if silicone rubber is used as the material for manufacturing the flexible gasket 1, the thickness of the two side surfaces can be close to 5 mm because the silicone rubber has good elasticity but poor strength, and if nitrile rubber is used as the material for manufacturing the flexible gasket 1, the thickness of the side surfaces can be relatively thin, which can reduce the weight and does not affect the structural performance, so the thickness of the two side surfaces of the nitrile rubber gasket can be close to 2 mm. For areas with high water pressure, the thickness of the two side surfaces of the flexible gasket 1 can be appropriately increased, for example, for the silicone rubber flexible gasket, the thickness of the two side surfaces can be increased to 8 mm, and for the nitrile rubber flexible gasket, the thickness of the two side surfaces can be increased to 5 mm. For areas with low water pressure, the thickness of the two side surfaces of the flexible gasket 1 needs to be appropriately reduced, for example, for the silicone rubber flexible gasket, the thickness of the two side surfaces can be reduced to 3 mm, and for the nitrile rubber flexible gasket, the thickness of the top surface can be increased to 1 mm.

[0089] In another technical solution, the height of the first end surface 110 is 1-8 mm.

[0090] In another technical solution, the thickness of the second end surface 120 is 0.5-5 mm.

[0091] In the above technical solution, from the sealing effect, the height of the first end surface 110 and the second end surface 120 should be able to effectively prevent water leakage under normal water pressure. If the height is too low, the sealing surface may not be tightly fitted under the long-term impact of water flow and pressure, and gaps may occur, leading to water leakage; and if the height is too high, not only the material cost and product volume will increase, but also the installation may be inconvenient, and even the overall structural stability may be affected. Under the general household faucet water pressure of 0.1-0.3 MPa, the height of the first end surface 110 cooperating with the outlet nozzle connector plane is 2-5 mm, and the height of the second end surface 120 cooperating with the aerator plane is 1-3 mm, which is relatively appropriate. Because the water flow impact force at the outlet nozzle connector is relatively large, a higher end surface height is needed to ensure the sealing effect; and the aerator mainly plays a role in dispersing water flow, and the sealing end surface height requirement is relatively low. In addition, in actual application, multiple angles can be considered, such as material properties: the elasticity, hardness and other properties of the rubber material used in the flexible gasket will affect the selection of the end surface height. Good elastic rubber can also fill the small unevenness of the sealing surface through its own deformation at a smaller height, achieving good sealing; and higher hardness rubber needs to increase the height appropriately to ensure sufficient contact area to achieve the sealing purpose. For example, when using silicon rubber which has good elasticity, the height of the second end surface 120 cooperating with the aerator plane can be close to 1 mm; if using nitrile rubber which has slightly higher hardness, the height of the second end surface 120 may need to be adjusted to about 2 mm. Installation space and structural design: the installation space inside the faucet is limited, and the end surface height cannot exceed the accommodable range. At the same time, it should be matched with the overall structural design of the faucet to ensure that the components are installed compactly and stably. If the space inside the faucet is narrow, the height of the end surface cooperating with the outlet nozzle connector plane may need to be controlled within 2-3 mm to avoid interference with other components; if the space is relatively spacious, the height can be increased to 4-5 mm to improve the sealing performance. For areas with high water pressure, to enhance the structural strength and resist the impact of high-pressure water flow, prevent the gasket from deforming excessively, the height of the first end surface 110 and the thickness of the second end surface 120 can be increased appropriately, the height of the first end surface 110 cooperating with the outlet nozzle connector plane can be increased to 5-8 mm, and the height of the second end surface 120 cooperating with the aerator plane can be increased to 3-5 mm. For areas with low water pressure, the height of the first end surface 110 and the thickness of the second end surface 120 can be reduced appropriately, the height of the first end surface 110 cooperating with the outlet nozzle connector plane can be reduced to 1-2 mm, and the height of the second end surface 120 cooperating with the aerator plane can be increased to 0.5-1 mm.
