Description

Technical Field

[0001] This application relates to the field of sanitary ware, and in particular to a faucet structure. Background Technology

[0002] In the existing faucet product field, the common structural forms are mainly divided into two types: hollow stainless steel shell and solid stainless steel shell.

[0003] For faucets with hollow stainless steel shells, the outlet pipe and valve are usually connected by a connecting pipe. However, in actual design and production, due to factors such as product structure layout, installation space limitations, and manufacturing precision, the outlet of the connecting pipe and the valve is often not precisely aligned on the same central axis. This axial deviation leads to gaps between the connecting pipe and the valve's outlet, causing leaks. Specifically, the gaps compromise the seal of the faucet's internal water passages, allowing water to easily seep through the gaps, resulting in leaks.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0009] A faucet structure is provided, the faucet structure comprising:

[0010] The valve is provided with a water outlet;

[0011] The water outlet assembly is located at the valve;

[0012] The movable connector includes a first end and a second end. The inner wall of the first end is provided with an inner spherical surface, and the outer periphery of the first end is provided with an outer spherical surface. The second end is connected to the water outlet assembly.

[0013] A locking connector, one end of which is disposed inside the movable connector, and the other end of which is detachably and sealingly connected to the valve;

[0014] The outlet has a first spherical surface on its inner wall and a second spherical surface on its outer periphery. The first end of the movable joint is axially limited between the first and second spherical surfaces, and a sealing structure is provided between its inner wall and the second spherical surface. The outer spherical surface is rotatably engaged with the first spherical surface, and the inner spherical surface is rotatably engaged with the second spherical surface, so that the first end of the movable joint can rotate around the locking joint and the valve.

[0015] In some embodiments, the first sphere, the second sphere, the inner sphere, and the outer sphere have the same center.

[0016] In some embodiments, the sealing structure is a first sealing ring.

[0017] In some embodiments, the inner wall of the outlet is provided with an internal thread, and the outer periphery of the locking connector is provided with an external thread adapted to the internal thread, and the locking connector is threadedly connected to the outlet.

[0018] In some embodiments, the inner wall of the locking connector is provided with a wrench structure for connecting a wrench.

[0019] In some embodiments, a second sealing ring is provided between the inner wall of the water outlet and the outer periphery of the locking connector.

[0020] In some embodiments, the water outlet assembly includes a water outlet pipe and a fixed connector. The fixed connector is fixedly disposed on the water outlet pipe and communicates with the water outlet pipe. Its inner wall is provided with a first inclined surface. The second end of the movable connector is movably disposed inside the fixed connector and a third sealing ring is provided between it and the inner wall of the fixed connector.

The outer surface of the valve core seat has a spherical surface. The outer diameter of the valve core seat is smaller than the inner diameter of the valve body and is disposed inside the valve body. The valve core seat is limited by contact with the positioning surface through the spherical surface. The valve core is disposed inside the valve body. The pressure cap is connected to the valve body and presses the valve core and valve core seat together to fix the valve core and valve core seat inside the valve body.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

[0025] The faucet structure of this application achieves angle self-adaptation by employing a movable joint. The outer spherical surface of the movable joint rotatably engages with the first spherical surface of the valve outlet inner wall, while the inner spherical surface of the first end of the movable joint rotatably engages with the second spherical surface of the locking joint outer periphery. This engagement allows the first end of the movable joint to rotate around the locking joint and the valve. During actual installation, even if the connecting pipe and the valve outlet are not on the same central axis, the movable joint can adapt to this deviation through its own rotation, automatically adjusting to the appropriate angle, thus avoiding gaps caused by misalignment. Furthermore, the faucet structure of this application includes a sealing structure between the inner wall of the first end of the movable joint and the second spherical surface of the locking joint. When the movable joint rotates to adapt to different axis conditions, the sealing structure maintains the seal between the movable joint and the locking joint, preventing water leakage from the gap between them. This ensures the sealing of the internal water passages of the faucet and effectively solves the problem of leakage caused by gaps at the connection point due to misalignment between the connecting pipe and the valve outlet.

Detailed Implementation

[0038] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0039] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0040] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0041] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0042] In the actual design and production of existing hollow faucet structures, due to various factors such as product structure layout, installation space limitations, and manufacturing process precision, the water outlet of the connecting pipe and the valve is often difficult to precisely align on the same central axis. This axial deviation can lead to gaps between the connecting pipe and the water outlet pipe or valve, resulting in leakage. Specifically, the gaps compromise the sealing of the faucet's internal water passages, allowing water to easily seep through the gaps and cause leakage.

[0043] To address the aforementioned technical problems, this embodiment provides a faucet structure.

[0044] Figure 1 This is an exploded view of the faucet structure in an embodiment of this application. Figure 2 This is a cross-sectional view of the faucet structure in an embodiment of this application. Figure 3 This is a schematic diagram of the faucet structure in an embodiment of this application. Figure 4 yes Figure 3 A schematic diagram of region A in the middle. Figure 5 This is a schematic diagram of the faucet connector in an embodiment of this application, where the connecting pipe and the valve outlet are not aligned.

[0045] See Figures 1 to 5 As shown, the faucet structure in this embodiment includes: valve 1, water outlet assembly 2, movable connector 3, and locking connector 4.

[0046] Valve 1 introduces water flow through an inlet pipe, controls the water circuit switch, and is equipped with an outlet 11. The outlet assembly 2 is fixedly installed on valve 1 and is used to output water flow.

[0047] The movable connector 3 is used to connect the water outlet assembly 2 and the valve 1. It includes a first end 31 and a second end 32. The inner wall of the first end 31 is provided with an inner spherical surface 311, and the outer periphery of the first end 31 is provided with an outer spherical surface 312. The second end 32 is connected to the water outlet assembly 2.

[0048] One end of the locking connector 4 is located inside the movable connector 3, and the other end is detachably and sealingly connected to the valve 1.

[0049] Among them, such as Figure 3 and Figure 4 As shown, the inner wall of the outlet 11 is provided with a first spherical surface 111, and the outer periphery of the locking connector 4 is provided with a second spherical surface 41. The first end 31 of the movable connector 3 is axially limited between the first spherical surface 111 and the second spherical surface 41, and a sealing structure is provided between its inner wall and the second spherical surface 41. The sealing structure can be a first sealing ring 33. The outer spherical surface 312 is rotatably engaged with the first spherical surface 111, and the inner spherical surface 311 is rotatably engaged with the second spherical surface 41, so that the first end 31 of the movable connector 3 can rotate around the locking connector 4 and the valve 1. When the movable connector 3 rotates, the first sealing ring 33 can always maintain the sealing between the two to prevent water from leaking from the mating gap.

[0050] The first spherical surface 111, the second spherical surface 41, the inner spherical surface 311, and the outer spherical surface 312 all have the same center point. The concentricity of all spherical surfaces ensures that the movable joint 3 rotates smoothly around a single center point, eliminating problems such as uneven wear, jamming, or uneven rotation caused by deviation of the center point.

[0051] It is understandable that the centers of the first sphere 111, the second sphere 41, the inner sphere 311, and the outer sphere 312 may be slightly off-center, as long as it does not affect rotation.

[0052] like Figure 3 and Figure 4 As shown, in addition to using the existing method, the locking connector 4 and valve 1 can be detachably and sealed together by the following method: the inner wall of the outlet 11 is provided with an internal thread 112, the outer periphery of the locking connector 4 is provided with an external thread 42 that is adapted to the internal thread 112, and the locking connector 4 is threadedly connected to the outlet 11.

[0053] like Figure 4 As shown, the inner wall of the locking connector 4 is further provided with a wrench structure 43 for connecting a wrench, which is used to rotate the locking connector 4.

[0054] See Figure 3 and Figure 4 As shown, a second sealing ring 44 is provided between the inner wall of the outlet 11 and the outer periphery of the locking connector 4.

[0055] like Figure 3 and Figure 4As shown, in one embodiment of the water outlet assembly 2, the water outlet assembly 2 includes a water outlet pipe 21 and a fixed connector 22. The fixed connector 22 is fixedly disposed on and connected to the water outlet pipe 21. Its inner wall is provided with a first inclined surface 221. The second end 32 of the movable connector 3 is movably disposed inside the fixed connector 22, and a third sealing ring 222 is provided between it and the inner wall of the fixed connector 22. A second inclined surface 321 is provided on the outer periphery of the second end 32, and the second inclined surface 321 is clearance-fitted with the first inclined surface 221. This fit allows the second end 32 of the movable connector 3 to be movably disposed inside the fixed connector 22, providing a certain amount of space between the movable connector 3 and the water outlet assembly 2, further enhancing the flexibility of the connection. This allows the movable connector 3 to swing relative to the fixed connector 22 to compensate for positional deviations during installation. Simultaneously, the third sealing ring 222 is provided between the second end 32 of the movable connector 3 and the inner wall of the fixed connector 22 to prevent water leakage from the gap between them.

[0056] like Figure 2 and Figure 3 As shown, the valve 1 is equipped with a valve body 12, and the fixed joint 22 can be fixed by welding, threaded connection or other means to ensure a stable connection between the water outlet component 2 and the valve 1.

[0057] See Figure 1 and Figure 2 As shown, other structures and components of valve 1 can be selected as the same as those of the existing valve 1 as needed. For example, valve 1 also includes a handle 13, a valve core 14, a valve core seat 15, and other structures.

[0058] For example, valve 1 includes a valve body 12, a handle 13, a valve core 14, a valve core seat 15, and a pressure cap 16. The valve body 12 has an inner bore 121, and a positioning surface 122 is provided inside the inner bore 121. The outer surface of the valve core seat 15 has a spherical surface 150 that matches the positioning surface 122. The outer diameter of the valve core seat 15 is smaller than the inner diameter of the valve body 12, so that the valve core seat 15 passes through the valve body 12 and is installed inside the valve body 12. The valve core seat 15 is limited by contact with the positioning surface 122 via the spherical surface 150. The valve core 14 is disposed inside the valve body 12. The pressure cap 16 is threaded to the valve body 12 and presses against the valve core 14 and valve core seat 15, so that the valve core 14 and valve core seat 15 are fixedly disposed inside the valve body 12. The handle 13 is connected to the valve core 14. The valve core seat 15 relies on the spherical surface 150 of its outer surface to contact the positioning surface 122 inside the inner hole 121 of the valve body 12. This cooperation between the spherical surface 150 and the positioning surface 122 achieves limiting and determines the position of the valve core seat 15 inside the valve body 12. After the pressure cap 16 is connected to the valve body 12, it applies pressure to the valve core 14 and the valve core seat 15, pressing them tightly and fixing them firmly inside the valve body 12. This ensures the relative position stability between the components of the valve 1 and effectively prevents the valve core 14 and the valve core seat 15 from loosening or shifting due to fluid impact, vibration, or other factors during operation, providing a structural foundation for the normal operation of the valve 1.

[0059] See Figure 4 and Figure 5 As shown above, the faucet structure of this application achieves angle self-adaptation by employing a movable joint 3. The outer spherical surface 312 of the movable joint 3 is rotatably engaged with the first spherical surface 111 of the inner wall of the outlet 11 of the valve 1, while the inner spherical surface 311 of the first end 31 of the movable joint 3 is rotatably engaged with the second spherical surface 41 of the outer periphery of the locking joint 4. This engagement allows the first end 31 of the movable joint 3 to rotate around the locking joint 4 and the valve 1. In actual installation, even if the connecting pipe and the outlet 11 of valve 1 are not on the same central axis, the movable joint 3 can adapt to this deviation by rotating itself and automatically adjust to the appropriate angle, thereby avoiding gaps caused by misalignment. At the same time, the faucet structure of this application has a sealing structure between the inner wall of the first end 31 of the movable joint 3 and the second spherical surface 41 of the locking joint 4. When the movable joint 3 rotates to adapt to the misalignment, the sealing structure can always maintain the sealing between the movable joint 3 and the locking joint 4, preventing water from leaking from the gap between them, ensuring the sealing of the water circuit inside the faucet, and effectively solving the problem of water leakage caused by gaps at the connection due to misalignment between the connecting pipe and valve 1.
