Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen and bathroom equipment technology, and in particular to a faucet structure. Background Technology
[0002] A faucet is a widely used water outlet device in daily life and kitchen and bathroom facilities. To make the water flow gentle and reduce splashing, an aerator is usually installed at the outlet end of its water channel. This aerator is mostly of a detachable structure, which is convenient for regular disassembly and cleaning to prevent the accumulation of scale and impurities, and to ensure water quality and user experience.
[0003] To ensure a tight seal between the aerator and the water outlet channel, a sealing ring is typically placed between their mating surfaces. However, in existing technologies, the sealing ring is often a separate component, its positioning relying on clamping or interference fit during aerator installation. When the aerator is disassembled, the sealing ring is prone to detaching due to loss of restraint, causing it to come off with the aerator. This type of structure has the following drawbacks: the sealing ring is easily lost, and users may forget to include it when reinstalling the aerator, causing leakage or seepage; even if the sealing ring is reinstalled, due to the lack of a reliable positioning structure, it may not be accurately aligned or fully embedded in the mating position during aerator installation, resulting in insufficient contact between the sealing surfaces and thus affecting sealing performance. Utility Model Content
[0004] This utility model addresses the technical problems existing in the prior art by providing a faucet structure that can prevent the sealing ring from being lost or improperly installed.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a faucet structure, including a valve body, the valve body having a water outlet channel, and an aerator installed at the water outlet end of the water outlet channel; a sealing ring is provided at the water outlet end of the water outlet channel, the sealing ring sealing the fitting gap between the water outlet end and the aerator; when the aerator is disassembled, the sealing ring remains at the water outlet end of the water outlet channel and does not detach with the aerator.
[0006] In a preferred embodiment, the sealing ring is installed at the water outlet end of the water outlet channel, and a limiting structure for axial and / or radial positioning of the sealing ring is provided between the water outlet end of the water outlet channel and the sealing ring.
[0007] In a preferred embodiment, the limiting structure includes a limiting protrusion and a limiting groove that fit together, with one of the limiting protrusion and the limiting groove located at the water outlet end, and the other of the limiting protrusion and the limiting groove located at the sealing ring.
[0008] In a preferred embodiment, the limiting protrusion is disposed on the end face of the water outlet end, and the limiting protrusion includes an annular body extending along the water outlet direction of the water outlet channel, and an annular boss disposed on the outer side of the annular body. The limiting groove is disposed on the end face of the sealing ring facing away from the aerator, and is annular in shape and matches the limiting protrusion.
[0009] In a preferred embodiment, the bubbler includes a housing and a bubbler body disposed inside the housing, wherein the sealing ring is partially embedded in the housing and abuts against the periphery of the end face of the bubbler body.
[0010] In a preferred embodiment, the periphery of the aerator body end face is provided with annular ribs, which abut against the end face of the sealing ring.
[0011] In a preferred embodiment, the water outlet channel is a water outlet pipe built into the valve body, and the valve body has an opening corresponding to the water outlet end of the water outlet pipe, and the aerator is installed in the opening.
[0012] In a preferred embodiment, the valve body is provided with a vertically penetrating mounting cavity, a through-pipe channel, and the opening. One end of the through-pipe channel is laterally connected to the mounting cavity, and the other end is connected to the opening. A valve seat is installed in the mounting cavity, and a valve core is installed in the valve seat. The water outlet pipe passes through the through-pipe channel, and the water inlet end of the water outlet pipe is connected to the water outlet provided in the valve seat.
[0013] In a preferred embodiment, the inlet end of the outlet pipe is inserted into the outlet of the valve seat, and the valve seat is connected to a screw, the tail of which abuts against the outer wall of the inlet end of the outlet pipe to prevent the inlet end of the outlet pipe from exiting the outlet.
[0014] In a preferred embodiment, the valve core is a mixing valve core, and the valve seat is provided with a cold water inlet and a hot water inlet. The cold water inlet is connected to a cold water inlet pipe, and the hot water inlet is connected to a hot water inlet pipe.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This utility model features a sealing ring at the outlet end of the water outlet channel. This sealing ring seals the gap between the outlet end and the aerator, and remains at the outlet end of the water outlet channel when the aerator is disassembled, preventing it from detaching with the aerator. This design fundamentally solves the problem of sealing rings easily falling off or being lost in existing technologies due to independent installation and reliance on the aerator for clamping. It effectively prevents users from forgetting the sealing ring when reinstalling the aerator, significantly improving reliability. Furthermore, since the sealing ring is located on the outlet end, its position is not affected by the aerator installation process, requiring no additional alignment or adjustment by the user. Therefore, the sealing ring is already in the correct position when the aerator is installed, achieving automatic alignment and ensuring full contact of the sealing surface. This prevents seal failure due to improper installation, thereby improving leak-proof performance during long-term use.
[0017] 2. Preferably, the sealing ring is installed at the outlet end of the water outlet channel, and a limiting structure for axial and / or radial positioning of the sealing ring is provided between the outlet end of the water outlet channel and the sealing ring. This design effectively prevents the sealing ring from axially slipping or radially shifting during assembly or use, ensuring that it remains in the predetermined position during the installation and disassembly of the aerator, thus avoiding sealing failure due to positional displacement.
[0018] 3. As a preferred embodiment, the limiting structure includes a limiting protrusion and a limiting groove. This design achieves dual limiting of the sealing ring through a structured fitting method, which significantly improves the positioning accuracy and assembly reliability of the sealing ring and avoids sealing failure caused by positional deviation.
[0019] 4. As a preferred embodiment, the water outlet channel is a water outlet pipe built into the valve body. The valve body has an opening corresponding to the water outlet end of the water outlet pipe, and the aerator is installed in this opening. This design has multiple technical advantages: Firstly, the split structure allows for differentiated material selection—the valve body can be made of lower-cost metals (such as zinc alloy) or engineering plastics, while the water outlet pipe, which is in direct contact with water, can be made of safe materials such as stainless steel, copper, or food-grade plastics that meet drinking water hygiene standards, thus balancing structural strength, cost control, and water quality safety. Secondly, this structure allows the water outlet pipe and sealing ring to be pre-assembled outside the valve body (i.e., "external") before being inserted into the valve body as a whole, avoiding the operational difficulties of precision assembly in a narrow internal cavity and significantly improving assembly efficiency and positioning accuracy.
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the faucet structure of the present invention is not limited to the embodiments. Attached Figure Description

[0034] In this utility model, the use of terms such as "upper," "lower," "inner," "outer," and "top / bottom" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings. These terms are used solely for the purpose of describing the utility model and do not indicate or imply that the device must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0035] Furthermore, in the description of this utility model, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0036] Please see Figures 1-12 As shown, this utility model discloses a faucet structure including a valve body 1. The valve body 1 has a water outlet channel, and an aerator 2 is installed at the water outlet end of the water outlet channel. A sealing ring 3 is provided at the water outlet end of the water outlet channel. The sealing ring 3 seals the gap between the water outlet end and the aerator 2. When the aerator 2 is removed, the sealing ring 3 remains firmly held at the water outlet end of the water outlet channel and does not detach with the aerator 2. This design fundamentally solves the problem of the sealing ring 3 being independently installed and easily falling off or being lost due to reliance on the aerator 2 for clamping in traditional faucet structures, significantly improving the reliability of the product and the user experience.
[0037] In this embodiment, the sealing ring 3 is installed at the water outlet end of the water outlet channel, and a limiting structure for axial and / or radial positioning of the sealing ring 3 is provided between the water outlet end of the water outlet channel and the sealing ring 3. In other embodiments, the sealing ring 3 is not installed independently at the water outlet end of the water outlet channel, but is manufactured integrally with the water outlet end of the water outlet channel by injection molding.
[0038] As a preferred embodiment, the water outlet channel is a water outlet pipe 4 built into the valve body 1, and the sealing ring 3 is installed at the water outlet end of the water outlet pipe 4. The valve body 1 has an opening 11 corresponding to the water outlet end of the water outlet pipe 4, and the aerator 2 is installed in the opening 11. This design allows for differentiated material selection through a split structure: the valve body 1 can be made of low-cost metals (such as zinc alloy) or engineering plastics, while the water outlet pipe 4, which is in direct contact with water, can be made of safe materials such as stainless steel, copper, or food-grade plastics that meet drinking water hygiene standards, thus balancing structural strength, cost control, and water quality safety. On the other hand, it allows the water outlet pipe 4 and the sealing ring 3 to be pre-assembled outside the valve body 1 (i.e., "external") before being inserted into the valve body 1 as a whole, avoiding the operational difficulties of precision assembly in the narrow internal cavity of the valve body 1, and significantly improving assembly efficiency and positioning accuracy.
[0039] like Figures 2-4 As shown, the limiting structure includes a limiting protrusion 41 and a limiting groove 31 that fit together. One of the limiting protrusion 41 and the limiting groove 31 is located at the water outlet end of the water outlet channel (i.e., the water outlet pipe 4), and the other of the limiting protrusion 41 and the limiting groove 31 is located at the sealing ring 3. In this embodiment, the limiting protrusion 41 is located at the water outlet end of the water outlet channel (i.e., the water outlet pipe 4), and the limiting groove 31 is located at the sealing ring 3, but this is not a limitation. Specifically, the limiting protrusion 41 is located on the end face of the water outlet end of the water outlet pipe 4. The limiting protrusion 41 includes an annular body 411 extending along the water outlet direction of the water outlet pipe 4, and an annular boss 412 located on the outer side of the annular body 411. Specifically, the longitudinal section of the limiting protrusion 41 is L-shaped, and the horizontal extension of the L-shape corresponds to the annular boss 412. The limiting groove 31 is located on the end face of the sealing ring 3 facing away from the bubbler 2. It is annular and matches the limiting protrusion 41. That is, the structure and size of the limiting groove 31 match the limiting protrusion 41. The two achieve dual axial and radial positioning of the sealing ring 3 through fitting.
[0040] like Figure 2 As shown, the aerator 2 includes a cylindrical outer shell 21 and an aerator body 22 disposed inside the outer shell 21. When the aerator 2 is installed into the opening 11 of the valve body 1, the sealing ring 3 is partially embedded in the outer shell 21 and abuts against the periphery of the end face of the aerator body 22. The aerator body 22 has an internal air-water mixing chamber, whose main function is to mix water and air in a set ratio to form a delicate, soft, and low-noise water output, effectively improving user comfort and achieving water conservation. One end of the aerator body 22 located inside the valve body 1 is the mounting end face, and the periphery of this end face is provided with annular ribs 221. When the aerator 2 is fitted into the opening 11 of the valve body 1 and tightened or pushed into place, its annular ribs 221 form a contact-type abutment fit with the end face of the sealing ring 3, applying uniform axial pressure to the end face of the sealing ring 3, causing the sealing ring 3 to undergo elastic compression deformation, thereby achieving effective sealing between the water outlet pipe 4 and the aerator 2.
[0041] The valve body 1 has a vertically penetrating mounting cavity 12, a through-pipe channel 13, and the aforementioned opening 11. One end of the through-pipe channel 13 is laterally connected to the mounting cavity 12, and the other end is connected to the opening 11. A valve seat 5 is installed inside the mounting cavity 12, and a valve core 6 is installed on the valve seat 5. Specifically, a pressure cap 7 is threaded to the top of the mounting cavity 12 of the valve body 1. The pressure cap 7 fixes the valve seat 5 and the valve core 6 inside the mounting cavity 12 of the valve body 1. The valve stem of the valve core 6 extends upward and is connected to a handle 8 by a set screw 9 and a decorative buckle 10. A decorative cover 20 is provided between the handle 8 and the pressure cap 7 to cover the valve core 6. A water outlet pipe 4 passes through the through-pipe channel 13, and the inlet end of the water outlet pipe 4 is connected to the water outlet 51 of the valve seat 5. Specifically, the inlet end of the outlet pipe 4 is inserted into the outlet 51 of the valve seat 5. The valve seat 5 is connected to a screw 52, the tail of which abuts against the outer wall of the inlet end of the outlet pipe 4. Figure 2 As shown, this effectively prevents the water outlet pipe 4 from loosening or coming off due to water pressure impact during use, ensuring the sealing and structural stability of the connection between the water outlet pipe 4 and the outlet.
[0042] The valve core 6 of this utility model is a mixing valve core, preferably a thermostatic valve core. The bottom of the valve seat 5 is provided with a cold water inlet and a hot water inlet. The cold water inlet is connected to a cold water inlet pipe 30 so as to connect to a cold water source through the cold water inlet pipe 30. The hot water inlet is connected to a hot water inlet pipe 40 so as to connect to a hot water source through the hot water inlet pipe 40.
[0043] The assembly process of the faucet structure of this utility model is as follows:
[0044] First, place the sealing ring 3 onto the outlet end of the water outlet pipe 4, and use the limiting protrusion 41 and the limiting groove 31 to complete the positioning. Then, insert the water outlet pipe 4 with the sealing ring 3 installed into the other end of the pipe passage 13 through the opening 11 of the valve body 1. When the inlet end of the water outlet pipe 4 is fully inserted into the outlet 51 of the valve seat 5, screw 52 into the valve seat 5 along the axial direction until the tail of the screw 52 hits the outer wall of the inlet end of the water outlet, thereby achieving axial limiting and fastening of the water storage end and preventing it from loosening or coming out under water pressure impact. After the water outlet pipe 4 is fixed, install the valve core 6 inside the valve seat 5, and then connect the handle 8 to the valve stem of the valve core 6. Finally, screw or push the aerator 2 into the opening 11 of the valve body 1 until the annular rib 221 of the aerator body 22 abuts against the end face of the sealing ring 3.
[0045] In actual use, when users need to clean or replace aerator 2, they can simply unscrew or pull it out to complete the disassembly. Since the sealing ring 3 is fixed to the outlet end of the water outlet pipe 4 by a limiting structure, it will not detach with the aerator 2, avoiding the problem of omission during reinstallation due to the loss of the sealing ring 3 in traditional structures. At the same time, because the sealing ring 3 is always in the correct position, the aerator 2 can be automatically aligned during reinstallation, eliminating the need for additional alignment or adjustment by the user, greatly simplifying the maintenance process and improving operational convenience.
[0046] Therefore, this utility model fundamentally solves the technical pain points of the sealing ring 3 being easy to fall off and easy to miss during installation by fixing the sealing ring 3 and the water outlet pipe 4 in an integrated manner and using a limiting structure to achieve dual axial and radial positioning. At the same time, the use of a split structure design supports external pre-assembly and overall assembly, which significantly improves production efficiency and assembly accuracy. In addition, through differentiated material selection and structural optimization, it takes into account cost control, water quality safety and long-term reliability, and has significant technological progress and broad market application prospects.
[0047] The faucet structure of this utility model is identical to or can be implemented using existing technologies for the parts not described herein.
