Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom equipment technology, and in particular to faucets, faucets and water purifiers. Background Technology

[0002] As a core component connecting the water purification system to the user, the faucet in a water purifier directly impacts the user experience in terms of functionality and stability. Especially in modern households, users increasingly demand convenience and flexibility in using water purifiers, making adjustable faucets a mainstream market requirement.

[0003] However, most adjustable faucets on the market today consist of a faucet body and a faucet sleeve, which are interlocked to allow the faucet body to swing around the axis of the faucet sleeve. To ensure structural stability, the faucet body and faucet sleeve are typically engaged along the axis of the faucet sleeve using a snap-fit ​​mechanism (e.g., the inner wall of the faucet sleeve has an annular snap protrusion, and the part of the faucet body that inserts into the faucet sleeve has an annular groove; when the faucet body is inserted into the faucet sleeve, the annular snap protrusion is located within the annular groove, allowing the faucet body to rotate relative to the faucet sleeve). However, with prolonged use, this snap-fit ​​mechanism can wear and deform, causing the faucet body and faucet sleeve to loosen along the axis of the faucet sleeve, resulting in wobbling of the faucet body relative to the faucet sleeve. This affects the faucet's lifespan and even the user experience.

[0004] Therefore, a hinge assembly is urgently needed to solve the above problems. Utility Model Content

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figures 1-4 As shown, this embodiment provides a faucet, which includes a faucet sleeve 3, a faucet body 2, and a rotating shaft assembly 1. The rotating shaft assembly 1 includes an inner rotating cylinder 11, an outer rotating cylinder 12, and a locking nut 13. The inner rotating cylinder 11 passes through the outer rotating cylinder 12 along a predetermined direction a and rotates in cooperation with the outer rotating cylinder 12. One of the faucet sleeve 3 and the faucet body 2 is fixedly connected to one end of the inner rotating cylinder 11, and the faucet sleeve 3 or the faucet body 2 abuts against one end of the outer rotating cylinder 12 along the predetermined direction a. The locking nut 13 is screwed to the other end of the inner rotating cylinder 11, and the locking nut 13 abuts against the other end of the outer rotating cylinder 12 along the predetermined direction a. The other of the faucet sleeve 3 or the faucet body 2 is fixedly connected to the outer rotating cylinder 12. When the faucet body 2 is driven to rotate relative to the faucet sleeve 3, the inner rotating cylinder 11 rotates relative to the outer rotating cylinder 12, thereby realizing the rotation of the faucet body 2 relative to the faucet sleeve 3. One of the faucet sleeve 3 and the faucet body 2, which are connected to one end of the inner rotating cylinder 11, abuts against one end of the outer rotating cylinder 12 along a preset direction a. The locking nut 13 is screwed to the other end of the inner rotating cylinder 11 and abuts against the other end of the outer rotating cylinder 12 along the preset direction a. This achieves relative fixation of the inner rotating cylinder 11 and the outer rotating cylinder 12 along the preset direction a. When the faucet is used for a long time, the rotating shaft assembly 1 wears or deforms, causing relative displacement of the inner rotating cylinder 11 and the outer rotating cylinder 12 along the preset direction a. Simply rotate the locking nut 13 to re-fix the inner rotating cylinder 11 and the outer rotating cylinder 12 along the preset direction a, thus preventing the faucet body 2 and the faucet sleeve 3 from loosening along the preset direction a and preventing relative swaying of the faucet body 2 and the faucet sleeve 3, thereby improving the user experience.

[0039] In this embodiment, the faucet body 2 is connected to one end of the inner rotating cylinder 11, and the faucet sleeve 3 is connected to the outer rotating cylinder 12.

[0040] Optionally, the outer rotating cylinder 12 is inserted into the faucet sleeve 3 along a preset direction a and screwed to the faucet sleeve 3; and / or one end of the inner rotating cylinder 11 is inserted into the faucet body 2 and screwed to the faucet body 2. In this embodiment, the outer peripheral wall of the outer rotating cylinder 12 is provided with external threads, the inner peripheral wall of the faucet sleeve 3 is provided with internal threads, and the outer rotating cylinder 12 is inserted into the faucet sleeve 3 and screwed to the faucet sleeve 3. The outer peripheral wall of one end of the inner rotating cylinder 11 is provided with external threads, the inner peripheral wall of the faucet body 2, which is fitted onto one end of the inner rotating cylinder 11, is provided with internal threads, and one end of the inner rotating cylinder 11 is screwed to the faucet body 2. In other embodiments, the outer rotating cylinder 12 is inserted into the faucet sleeve 3 along a preset direction a and snapped to the faucet sleeve 3; and / or one end of the inner rotating cylinder 11 is inserted into the faucet body 2 and snapped to the faucet body 2.

[0041] Optionally, one end of the outer rotating cylinder 12 is recessed with a limiting groove 121 along a preset direction a, and the limiting groove 121 extends circumferentially around the outer rotating cylinder 12; one end of the inner rotating cylinder 11 is coaxially inserted into the faucet body 2, and the faucet body 2 is provided with a limiting pin 211. The limiting groove 121 is configured to engage with the limiting pin 211 along the preset direction a, and the arc length of the limiting pin 211 is less than the arc length of the limiting groove 121 around the circumferential direction of the outer rotating cylinder 12. In this embodiment, the faucet body 2 rotates relative to the faucet sleeve 3, thereby causing the inner rotating cylinder 11 to rotate relative to the outer rotating cylinder 12. During this process, the limiting pin 211 moves within the limiting groove 121, and the difference between the arc length of the limiting groove 121 and the arc length of the limiting pin 211 is the maximum arc length of the rotation of the faucet body 2 relative to the faucet sleeve 3.

[0042] Optionally, at least two limiting grooves 121 are provided, and the at least two limiting grooves 121 are arranged circumferentially around the outer rotating cylinder 12. At least two limiting pins 211 are provided, and the at least two limiting pins 211 are arranged circumferentially around the outer rotating cylinder 12. The at least two limiting pins 211 and the at least two limiting grooves 121 are arranged in a one-to-one correspondence.

[0043] Optionally, the rotating shaft assembly 1 further includes a first sealing ring 14, which is sleeved on the inner rotating cylinder 11 and located between the inner rotating cylinder 11 and the outer rotating cylinder 12, with the inner rotating cylinder 11 and the outer rotating cylinder 12 clamping the first sealing ring 14. In this embodiment, the first sealing ring 14 can prevent external water or water vapor from entering the faucet sleeve 3 through the gap between the outer rotating shaft and the inner rotating shaft. Specifically, the first sealing ring 14 is made of corrosion-resistant rubber material.

[0044] Optionally, the rotating shaft assembly 1 further includes a washer 15, which is sleeved on the inner rotating cylinder 11 and located between the locking nut 13 and the outer rotating cylinder 12. In this embodiment, if the washer 15 is not provided, during the relative rotation of the inner rotating cylinder 11 and the outer rotating cylinder, the inner rotating cylinder 11 may directly drive the locking nut 13 to rotate. The circumferential force applied by the inner rotating cylinder 11 will directly act on the locking nut 13, thereby causing the locking nut 13 and the faucet body 2 to fail to limit the relative position of the inner rotating cylinder 11 and the outer rotating cylinder. If the washer 15 is provided, the circumferential force applied by the inner rotating cylinder 11 will act on the locking nut 13 through the washer 15, thereby weakening the force acting on the locking nut 13 and effectively improving the loosening of the locking nut 13.

[0045] Optionally, the outer wall of the inner rotating cylinder 11 is provided with a first annular protrusion 111, which is arranged circumferentially around the inner rotating cylinder 11 and is positioned opposite to the inner wall of the outer rotating cylinder 12; and / or, the inner wall of the outer rotating cylinder 12 is provided with a second annular protrusion, which is arranged circumferentially around the inner rotating cylinder 11 and is positioned opposite to the outer wall of the inner rotating cylinder 11. In this embodiment, the first annular protrusion 111 and / or the second annular protrusion are provided to reduce the contact area between the outer wall of the inner rotating cylinder 11 and the inner wall of the outer rotating cylinder 12, thereby reducing the friction between the inner rotating cylinder 11 and the outer rotating cylinder 12 and reducing the force required for the operator to drive the faucet body 2 to rotate relative to the faucet sleeve 3.

[0046] Optionally, the surface of the first annular protrusion 111 opposite to the outer rotating cylinder 12 is recessed with a limiting ring 1111, and / or the surface of the second annular protrusion opposite to the inner rotating cylinder 11 is recessed with a limiting ring 1111; the rotating shaft assembly 1 also includes a first sealing ring 14, which is located within the limiting ring 1111. In this embodiment, the first sealing ring 14 is located within the limiting ring 1111 to restrict the position of the first sealing ring 14, preventing the first sealing ring 14 from coming out of the gap between the inner rotating cylinder 11 and the outer rotating cylinder 12, and preventing sealing failure.

[0047] If the inner rotating cylinder 11 is provided with only one first annular protrusion 111 and the outer rotating cylinder 12 is not provided with a second annular protrusion, when the inner rotating cylinder 11 rotates relative to the outer rotating cylinder 12, the inner rotating cylinder 11 is prone to swinging with the first annular protrusion 111 as the fulcrum, which will cause the faucet body 2 to swing relative to the faucet sleeve 3. To avoid this problem, optionally, the outer wall of the inner rotating cylinder 11 is provided with at least two first annular protrusions 111, and the at least two first annular protrusions 111 are arranged at intervals along a preset direction a. The first annular protrusions 111 are arranged around the circumference of the inner rotating cylinder 11, and the first annular protrusions 111 are arranged opposite to the inner wall of the outer rotating cylinder 12. In this embodiment, at least two first annular protrusions 111 are provided at intervals along a preset direction a between the inner rotating cylinder 11 and the outer rotating cylinder 12, thereby forming multiple support points along the preset direction a between the inner rotating cylinder 11 and the outer rotating cylinder 12 to prevent the inner rotating cylinder 11 from swinging relative to the outer rotating cylinder 12. This arrangement can improve the stability of the inner rotating cylinder 11 when rotating relative to the outer rotating cylinder 12 and improve the user's experience.

[0048] Optionally, the faucet body 2 includes a first faucet section 21 and a second faucet section 22 that are interconnected. The first faucet section 21 is connected to the inner rotating cylinder 11, and the first faucet section 21 and the second faucet section 22 are arranged at an angle. The faucet also includes a connecting pipe 4, which passes through the first faucet section 21 and the second faucet section 22 in sequence. A pressure plate 221 is provided inside the second faucet section 22, and the pressure plate 221 abuts against the connecting pipe 4. In this embodiment, since the first faucet section 21 and the second faucet section 22 are arranged at an angle, under the action of the elastic force of the connecting pipe 4 itself, the connecting pipe 4 located in the second faucet section 22 swings towards returning to its original shape. At this time, the pressure plate 221 prevents the connecting pipe 4 located in the second faucet section 22 from returning to its original shape, thereby making the connecting pipe 4 abut against the pressure plate 221, so as to generate a large frictional force between the connecting pipe 4 and the pressure plate 221. When the faucet body 2 rotates relative to the faucet sleeve 3, the connecting pipe 4 rotates accordingly. The large frictional force generated between the connecting pipe 4 and the pressure plate 221 can prevent the displacement of the connecting pipe 4. In other embodiments, the connecting pipe 4 can also be pressed directly onto the inner wall of the second faucet 22 by the pressure plate 221.

[0049] Optionally, the faucet also includes a fixing component 5 for fixing the faucet sleeve to the mounting panel. The mounting panel has a through hole. The fixing component 5 includes a plug part 51, a connecting part 52, a second sealing ring 53, a washer 54, and a fastening nut 55. The plug part 51 is inserted into the end of the faucet sleeve 3 away from the rotating shaft assembly 1 and screwed to the faucet sleeve 3. One end of the connecting part 52 is inserted into the plug part 51 and screwed to the plug part 51. The other end of the connecting part 52 passes through the through hole and is located on the other side of the mounting panel so that the plug part 51 abuts against one side of the mounting panel. The washer 54 and the fastening nut 55 are sequentially fitted onto the connecting part 52 from the other side of the mounting panel. The fastening nut 55 is screwed to the connecting part 52. The outer diameter of the washer 54 is larger than the outer diameter of the through hole to achieve relative fixation between the faucet sleeve and the control panel. The second sealing ring 53 is sleeved on the connecting part 52 and located between the control panel and the plug-in part 51. The control panel and the plug-in part 51 clamp the second sealing ring 53 to prevent water on one side of the control panel from flowing to the other side of the control panel through the through hole.

[0050] Optionally, the connecting part 52 is a threaded tube, and the connecting tube 4 extends out from the threaded tube.

[0051] This embodiment also provides a water purifier, including the faucet described in the above solution.
