The elastic component is sleeved on the outer wall of the pull-out tube, and the elastic component includes at least two elastic elements and at least one annular joint, and the annular joint is located between two adjacent elastic elements, and the two adjacent elastic elements are connected via the annular joint; the pull-out component is in a working state, so that the elastic elements deform, so that the elastic component is in a working state; the elastic component is configured to drive the pull-out component to move to the initial state under the action of the elastic restoring force of the elastic elements.

[0005] In some exemplary embodiments, the annular joint includes a first mounting portion and a second mounting portion connected to each other, and a protrusion located between the first mounting portion and the second mounting portion. One of the two adjacent elastic members is connected to the first mounting portion, and the other of the two adjacent elastic members is connected to the second mounting portion. The outer diameter of the protrusion is larger than the outer diameter of the first mounting portion, larger than the outer diameter of the second mounting portion, and larger than the outer diameter of the elastic member.

[0006] In some exemplary embodiments, the annular joint is made of plastic.

[0007] In some exemplary embodiments, the first mounting portion, the second mounting portion, and the protrusion are integrally formed.

[0022] like Figure 1 , Figure 2A , Figure 2B , Figure 3 , Figure 4 , Figure 5A , Figure 5B As shown, this utility model embodiment provides a pull-out faucet, which may include a bent pipe assembly 10, a pull-out assembly 20, and an elastic assembly 30. Both the pull-out assembly 20 and the elastic assembly 30 can switch between an initial state and a working state. When the pull-out assembly 20 and the elastic assembly 30 are in the initial state, the pull-out faucet is in the initial state, as shown below. Figure 3 As shown, when the pull-out assembly 20 and the elastic assembly 30 are in working condition, the pull-out faucet is also in working condition, as... Figure 4 As shown. In this embodiment of the invention, the pull-out faucet is in its initial state, where water may or may not flow; and in its working state, where water may or may not flow. The initial state and working state simply represent two states of the pull-out faucet. The bend assembly 10 may include a faucet bend 11 and a water outlet nest 12. The faucet bend 11 may include an inlet end 111, an outlet end 112, and a receiving cavity 113. The inlet end 111 and the outlet end 112 are connected via the receiving cavity 113. The water outlet nest 12 is installed within the receiving cavity 113 and is close to the outlet end 112. For example, the water outlet nest 12 may snap onto the wall of the receiving cavity 113.

[0023] The pull-out assembly 20 may include a shower head 21, a pull-out tube 22, an inner tube 23, and a connector assembly 24. The connector assembly 24 may be disposed within the receiving cavity 113 of the faucet bend 11 and slide against the cavity wall of the receiving cavity 113. The inner tube 23 may be sleeved within the pull-out tube 22, and at least a portion of the inner tube 23 and the pull-out tube 22 may be disposed within the receiving cavity 113 of the faucet bend 11. One end of the pull-out tube 22 may be fixedly connected to the connector assembly 24, and the other end of the pull-out tube 22 may be fixedly connected to the shower head 21. One end of the inner tube 23 may be fixedly connected to the shower head 21, and the other end of the inner tube 23 may extend out of the receiving cavity 113 via the water inlet end 111 of the faucet bend 11. With the pull-out faucet in its initial state, part of the shower head 21 can be located within the receiving cavity 113 via the water outlet 112. During actual use, force can be applied to the shower head 21 outside the receiving cavity 113 to pull it out in a direction away from the bend assembly 10. Figure 4 As shown, the pull-out faucet is in working condition. Since one end of the inner tube 23 and one end of the pull-out tube 22 are fixedly connected to the shower head 21, the inner tube 23 and the pull-out tube 22 are pulled out in a direction away from the curved pipe assembly 10 under the action of the shower head 21, that is, the pull-out assembly 20 is in working condition.

[0024] The elastic component 30 is sleeved on the outer wall of the pull-out tube 22 and located within the receiving cavity 113 of the faucet bend 11, between the connector assembly 24 and the water outlet nest 12. Along the extending direction of the faucet bend 11, the connector assembly 24 and the water outlet nest 12 can limit the movement of the elastic component 30. The elastic component 30 may include multiple elastic elements 31 and multiple annular connectors 32. The multiple elastic elements 31 can be arranged sequentially along the extending direction of the faucet bend 11, and the annular connectors 32 are located between two adjacent elastic elements 31, and the two adjacent elastic elements 31 are connected via the annular connectors 32. For example, the elastic element 31 can be a spring. For example, the elastic component 30 may include two elastic elements 31 and one annular connector 32, or the elastic component 30 may include three elastic elements 31 and two annular connectors 32, or the elastic component 30 may include four elastic elements 31 and three annular connectors 32, etc. This embodiment of the invention does not limit the number of elastic elements 31 or the number of annular connectors 32 included in the elastic component 30.

[0025] The annular joint 32 may include a first mounting portion 321 and a second mounting portion 322 connected to each other, and a protrusion 323 located between the first mounting portion 321 and the second mounting portion 322. One of the two adjacent elastic members 31 is connected to the first mounting portion 321, and the other of the two adjacent elastic members 31 is connected to the second mounting portion 322. The outer diameter of the protrusion 323 is larger than the outer diameter of the first mounting part 321, larger than the outer diameter of the second mounting part 322, and larger than the outer diameter of the elastic member 31. The protrusion 323 slides in contact with the cavity wall of the receiving cavity 113 of the faucet bend 11. In this embodiment of the present invention, by refining the structure of the annular connector 32 and limiting the outer diameter of the protrusion 323 to be larger than the outer diameter of the first mounting part 321, larger than the outer diameter of the second mounting part 322, and larger than the outer diameter of the elastic member 31, contact between the elastic member 31 and the cavity wall of the receiving cavity 113 can be avoided, and the contact area between the elastic component 30 and the cavity wall of the receiving cavity 113 can be reduced. In addition, the multiple spaced protrusions 323 can play a guiding role, improving the stability of the movement of the elastic component 30 and improving the problem of excessive noise during the pulling process of the existing pull-out faucet.

[0026] In actual use, when force is applied to the shower head 21, the inner pipe 23 and the pull-out pipe 22 are pulled out away from the bend assembly 10 under the action of the shower head 21. Figure 4 As shown, since one end of the pull-out tube 22 is fixedly connected to the connector assembly 24, the connector assembly 24 moves towards the water outlet 112 of the faucet bend 11 under the drive of the pull-out tube 22. Due to the movement of the connector assembly 24, multiple elastic elements 31 are compressed under force, that is, the elastic element 30 is in the working state. In the embodiment of this utility model, the design of the elastic element 31 being compressed under force so that the elastic element 30 is in the working state can reduce the length of the faucet bend 11, reduce the cost of the product, and reduce the space occupied by the pull-out faucet, thereby improving the design quality of the product.

[0027] When the force applied to the shower head 21 is removed, the multiple elastic elements 31 return to their initial state under the action of elastic force, such as... Figure 3 As shown, under the elastic force of the elastic element 31, the connector assembly 24 moves toward the water inlet end 111 of the faucet bend 11. Since one end of the pull tube 22 is fixedly connected to the connector assembly 24, the pull tube 22, the inner tube 23 and the shower head 21 all return to their initial state under the action of the connector assembly 24.

[0028] In some exemplary embodiments, the material of the annular connector 32 can be plastic. For example, the plastic can be any one or more of acrylonitrile-butadiene-styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM), polyvinyl chloride (PVC), nylon (PA), or polyethylene (PE). In the embodiments of this utility model, by designing the material of the annular connector 32 as a plastic material, the elastic component 30 and the receiving cavity 113 of the faucet bend 11 can achieve a plastic-metal fit. Compared with a metal-to-metal fit, this can reduce the noise generated by the contact between the two and improve the user experience.

[0029] In some exemplary embodiments, the minimum gap between the protrusion 323 and the cavity wall of the receiving cavity 113 can range from 0.50 mm to 0.80 mm, for example, it can be 0.75 mm. In the embodiments of this utility model, by limiting the minimum gap between the protrusion 323 and the cavity wall of the receiving cavity 113, the compactness of the structural layout can be improved while ensuring the smooth movement of the elastic component 30. Furthermore, the cavity wall of the receiving cavity 113 can provide a certain guiding effect on the movement of the protrusion 323, which is beneficial to the stability of the movement of the protrusion 323.

[0030] In some exemplary embodiments, the difference between the outer diameter of the protrusion 323 and the outer diameter of the elastic member 31 can range from 2.0 mm to 3.0 mm, for example, 3.0 mm or 2.5 mm. In the embodiments of this invention, the outer diameter refers to the maximum diameter. In the embodiments of this invention, by limiting the range of the difference between the outer diameter of the protrusion 323 and the outer diameter of the elastic member 31, metal-to-metal contact between the elastic member 31 and the cavity wall of the receiving cavity 113 can be avoided, and the elastic member 31 can be guaranteed to have sufficient elastic force. This can shorten the time for the elastic component 30 to return from the working state to the initial state, thereby improving product quality.

[0031] In some exemplary embodiments, such as Figure 3 , Figure 4 , Figure 5A As shown, the elastic member 31 can be sleeved on the outer wall of the first mounting part 321 and has an interference fit with the outer wall of the first mounting part 321, which simplifies the installation of the elastic member 31 and the first mounting part 321 and has sufficient connection reliability. Another elastic member 31 can be sleeved on the outer wall of the second mounting part 322 and has an interference fit with the outer wall of the second mounting part 322, which simplifies the installation of the elastic member 31 and the second mounting part 322 and has sufficient connection reliability.

[0032] In some exemplary embodiments, such as Figure 2A , Figure 2BAs shown, the first mounting part 321, the second mounting part 322, and the protrusion 323 can be an integral structure that is interconnected. For example, they can be integrally molded using injection molding, which can simplify the assembly of the annular connector 32 and reduce the manufacturing cost of the product.

[0033] In some exemplary embodiments, such as Figure 2A As shown, one end of the pull tube 22 can be provided with an external thread, which can realize the threaded connection between the pull tube 22 and the connector assembly 24. The assembly is simple and reliable, and no nut is required, which can reduce the number of parts and reduce the cost of the product.

[0034] In some exemplary embodiments, such as Figure 2A , Figure 3 , Figure 4 , Figure 5B As shown, the connector assembly 24 may include a water inlet connector 241, a sealing ring 242, and a gasket 243. The water inlet connector 241 has a mounting cavity, at least a portion of which may have internal threads. The sealing ring 242 and the gasket 243 may be sequentially disposed within the mounting cavity. A section of the pull-out tube 22 with external threads may extend into the mounting cavity. The internal and external threads may engage, thus achieving a threaded connection between the pull-out tube 22 and the water inlet connector 241. Alternatively, one end of the pull-out tube 22 may have internal threads, and at least a portion of the mounting cavity wall may have external threads, with the internal and external threads engaging. A portion of the inner tube 23 may extend out of the receiving cavity 113 via the mounting cavity, the gasket 243, and the sealing ring 242, which helps ensure the smooth movement of the inner tube 23.

[0035] Although the embodiments disclosed in this utility model are as described above, the content described is only for the purpose of facilitating understanding of this utility model and is not intended to limit this utility model. Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be defined by the appended claims.
