Description

Technical Field

[0001] This utility model relates to the field of faucets, and more particularly to a self-resetting pull-out faucet. Background Technology

[0002] In traditional pull-out faucets, a return spring structure is typically used to achieve the automatic retraction function of the shower hose. The return spring is located inside the bend and sleeved on the outside of the hose, and the elastic force of the spring drives the hose to return to its original position. However, because the spring needs to maintain sufficient preload to ensure the return function, the maximum elongation of the shower hose is limited by the spring's extension stroke, resulting in a short hose pull-out stroke. At the same time, during the pull-out and return process, the friction between the spring and the hose wall not only generates noise, but also causes the return force to decrease due to wear.

[0003] Based on the above, existing pull-out faucets need further improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing pull-out faucets and provide an automatic reset pull-out faucet. By replacing the reset spring structure with a reset component, the hose assembly is reset, increasing the pull-out stroke of the hose assembly, while avoiding the noise and reset force attenuation problems caused by the reset spring structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic reset pull-out faucet, comprising a faucet body, a bend, a hose assembly, a shower head, and a reset assembly. The faucet body is a hollow structure. The bend is disposed on the upper side of the faucet body and communicates with the faucet body. The hose assembly is disposed inside the bend and one end is connected to the faucet body, while the other end can extend and retract through the bend and connect to the shower head. The reset assembly is disposed on the faucet body, and the reset rope of the reset assembly is connected to the hose assembly. The reset rope can move with the hose assembly and provide a reset force.

[0006] This invention features a retractable hose assembly. A reset rope moves with the hose assembly and provides a reset force to achieve automatic reset. This ensures the hose assembly's pull-out stroke is not limited by the reset rope itself. Furthermore, because the reset rope moves synchronously with the hose assembly, it avoids friction with the hose wall, preventing frictional noise or wear that could affect the reset force. Compared to existing technologies, this invention's automatic reset pull-out faucet offers a longer pull-out stroke and a better user experience.

[0007] Preferably, the reset assembly includes a winding device. When the hose assembly is reset, one end of the reset rope is wound into the winding device. The winding device shortens the stretch length of the reset rope by winding it up, thereby driving the outer hose to slide towards the side closer to the reset assembly, thus achieving reset.

[0008] Preferably, the reset component includes a pull-down device, which is configured as a counterweight. When the hose assembly is reset, the pull-down device pulls the reset rope downward. Since the hose assembly is stretched by external pulling force, the hose assembly can be pulled out by overcoming the weight of the counterweight. When there is no external pulling force, the hose assembly retracts into the bend due to the weight of the counterweight, thus achieving reset.

[0009] Preferably, the hose assembly includes an outer hose and an inner hose. The faucet body is provided with a water outlet. The inlet end of the inner hose is connected to the water outlet. The outlet end of the inner hose passes through the inlet end of the outer hose and is placed inside the outer hose and is sealed to the outer hose. The outlet end of the outer hose is connected to the shower head. In use, the outer hose is stretched outward by pulling the shower head. After use, the shower head is released, and the outer hose automatically retracts into the bend under the winding of the reset component or by gravity.

[0010] Preferably, the reset rope is wound around the water inlet end of the external hose.

[0011] Preferably, a limiting step is provided on the inner side of the bend, and the inner diameter of the limiting step is smaller than the outer diameter of the water inlet end of the outer hose; the limiting step is used to limit the displacement of the water inlet end of the outer hose and prevent the outer hose from sliding completely outside the bend.

[0012] Preferably, the maximum length of the inner hose placed inside the outer hose is greater than the sliding stroke of the outer hose; to prevent the outer hose from detaching from the inner hose.

[0013] Preferably, the water inlet end of the external hose is provided with a limiting part, which is used to limit the winding position of the reset rope.

[0014] Preferably, the outer hose and the inner hose are flexible hoses.

[0015] Preferably, the reset rope is a flexible, non-elastic rope. Attached Figure Description

[0023] Example 1

[0024] See Figures 1 to 3 .

[0025] This embodiment discloses an automatic reset pull-out faucet 1, including a faucet body 2, a bend 3, a hose assembly 4, a shower head 5, and a reset component 6. The faucet body 2 is a hollow structure. The bend 3 is located on the upper side of the faucet body 2 and communicates with the faucet body 2. The hose assembly 4 is located inside the bend 3 and one end is connected to the faucet body 2, while the other end can extend and retract through the bend 3 and connect to the shower head. The reset component 6 is located on the faucet body 2, and the reset rope 61 of the reset component 6 is connected to the hose assembly 4. The reset rope 61 can move with the hose assembly 4 and provide a reset force.

[0026] The reset assembly 6 includes a winding device 62. When the hose assembly 4 is reset, one end of the reset rope 61 is wound into the winding device 62. In this solution, the reset rope 61 is used to connect the hose assembly 4 and the winding device 62. By winding the reset rope 61, the hose assembly 4 is reset. After reset, the space under the counter only needs to accommodate the winding device 62, the reset rope 61, and the cold / hot water inlet pipe connected to the faucet body 2. Compared with existing technologies that require the space under the counter to accommodate the cold / hot water inlet pipe, the hose, and the water outlet connection pipe, this solution occupies less space under the counter and has a more compact structure.

[0027] The hose assembly 4 includes an outer hose 41 and an inner hose 42. The faucet body 2 has a water outlet 21. The inlet end of the inner hose 42 is connected to the water outlet 21. The outlet end of the inner hose 42 passes through the inlet end of the outer hose 41 and is sealed to the outer hose 41. The outlet end of the outer hose 41 is connected to the shower head 5. In this design, the inner hose 42 is fixed, while the outer hose 41 can slide on the inner hose 42, thereby allowing the hose assembly 4 to extend or shorten.

[0028] The reset rope 61 is wound around the water inlet end of the outer hose 42. In this design, the reset rope 61 can be used to reset the outer hose 41 by pulling the water inlet end that is closest to the reset assembly 6, so that the length of the reset rope 61 is as small as possible while ensuring that the outer hose 41 can be reset.

[0029] The inner side of the bend 3 is provided with a limiting step 31, and the inner diameter of the limiting step 4 is smaller than the outer diameter of the water inlet end of the outer hose 41. The limiting step 31 in this solution is used to limit the sliding displacement of the outer hose 41 and prevent the outer hose 41 from detaching from the bend.

[0030] To prevent the outer hose 41 from detaching from the inner hose 42, the maximum length of the inner hose 42 placed inside the outer hose 41 is greater than the sliding stroke of the outer hose 42.

[0031] The water inlet end of the external hose 41 is provided with a limiting part 411, which is used to limit the winding position of the reset rope 61.

[0032] The outer hose 41 and inner hose 42 are designed as flexible hoses. The outer hose 41 and inner hose 42 of this design can be bent radially in any direction. During use, the outer hose 41 and inner hose 42 remain coaxially straight or bent at the same position.

[0033] To reduce the contact friction between the inner hose 42 and the inner surface of the outer hose 41, and to reduce the need for pulling and resetting force of the faucet shower head 5, the outer surface of the inner hose 42 is a smooth surface.

[0034] The reset rope 61 is a flexible, non-elastic rope. Specifically, the material of the reset rope 61 includes, but is not limited to, steel wire rope, nylon rope, carbon fiber rope, etc.

[0035] This invention features a telescopic hose assembly 4. The automatic reset function of the hose assembly 4 is achieved by the retraction or pull-down of the reset component 6. This ensures that the pull-out stroke of the hose assembly 4 is not limited by the reset component 6, and the retraction or pull-down of the reset component 6 does not create friction with the hose wall, thus avoiding frictional noise or wear and tear that could affect the reset force. Compared to existing technologies, the automatically reset pull-out faucet 1 of this invention has a longer pull-out stroke, resulting in a better user experience.

[0036] Example 2

[0037] See Figure 4 .

[0038] This embodiment is an improvement on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the reset force provided by the reset rope is gravity.

[0039] The reset assembly 6 includes a pull-down device 63, which is configured as a counterweight. When the hose assembly 4 is reset, the pull-down device 63 pulls the reset rope 61 downward.

[0040] In this embodiment, the hose assembly 4 is reset by pulling down the reset rope 61 by gravity, which makes the structure simpler.

[0041] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
