[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] See also Figure 1-Figure 5 The utility model provides a pull-out faucet, which includes a faucet body 1, a water outlet pipe 2, a pull-out pipe 3, a spiral pipe 4, a spring 5 and a water outlet head 6.

[0022] The faucet body 1 is a conventional faucet body 1 with a valve core assembly. The water outlet pipe 2 is a curved pipe structure and is rotatably arranged on the faucet body 1. The pull-out pipe 3 and the spiral tube 4 are both arranged in the water outlet pipe 2. The spiral tube 4 includes a fixed end 41 and a free end 42. The free end 42 of the spiral tube 4 is used to connect water. The free end 42 of the spiral tube 4 is connected to the valve core assembly on the faucet body 1. The free end 42 of the spiral tube 4 is connected to and connected to the pull-out pipe 3. The end of the pull-out pipe 3 is connected to the water outlet head 6. The pull-out pipe 3 and the spiral tube 4 are arranged in the water outlet pipe 2. The spring 5 connects the pull-out pipe 3 and the water outlet pipe 2 respectively. The pull-out pipe 3 can be pulled by an external force to extend or shorten the spiral tube 4, so that the water outlet head 6 leaves or approaches the water outlet pipe 2. The spring 5 and the spiral tube 4 can provide elastic force to move the pull-out pipe 3 to the initial position.

[0023] The spiral tube 4 includes a spiral state and a maximum elongation state. When in the spiral state, the pull-out tube 3 is located at the initial position. When in the maximum elongation state, the elastic force of the spring 5 pushes or pulls the pull-out tube 3. One end of the spring 5 abuts against the end of the water outlet pipe 2, and the other end of the spring 5 abuts against the pull-out tube 3; the spring 5 is a compression spring 5. A bushing 21 is provided at the end of the water outlet pipe 2, and the pull-out tube 3 passes through the bushing 21. The water outlet head 6 can abut against the bushing 21, and one end of the spring 5 abuts against the bushing 21. The pull-out tube 3 includes a water-passing joint 31 connected to the free end 42 of the spiral tube 4. The water-passing joint 31 includes a connecting flange 32, and the other end of the spring 5 abuts against the connecting flange 32.

[0024] In this embodiment, the water outlet pipe 2 includes a fixed straight section 22 and a free curved section 23 connected to the fixed straight section 22, the water outlet head 6 can leave or approach the end of the free curved section 23 of the water outlet pipe 2, when the spiral tube 4 is in a spiral state, the spiral tube 4 is located in the fixed straight section 22, when the spiral tube 4 is in a maximum elongation state, the spiral tube 4 partially enters the free curved section 23. The spring 5 is located in the free curved section 23.

[0025] When the spiral tube 4 is in the maximum elongation state, since the spiral tube 4 partially enters the free bend section 23, the elastic force of the spiral tube 4 will be affected. In extreme cases, the spiral tube 4 is in a completely stretched state, and the elastic force of the spiral tube 4 may disappear. At this time, the spring 5 can push the spiral tube 4 to return to the spiral state.

[0026] The faucet body 1 includes a fixed joint 11 , the water outlet pipe 2 is rotatably sleeved outside the fixed joint 11 , the upper end of the fixed joint 11 also includes a water outlet 12 , and the fixed end 41 of the spiral tube 4 is plugged into the water outlet 12 .

[0027] During use, the water outlet head 6 is first placed on the bushing 21, at which time the spiral tube 4 and the pull-out tube 3 are in the initial position, and the spiral tube 4 is in a coiled state. The user pulls the water outlet head 6 away from the water outlet pipe 2, and the pull-out tube 3 pulls the free end 42 of the spiral tube 4, so that the spiral tube 4 gradually extends. The pull-out tube 3 can pull the spiral tube 4 to any length between the coiled state and the maximum extension state. At this time, the spring 5 is in a compressed state, and the spring 5 always provides the elastic force for the pull-out tube 3 to return to the initial position, and the spiral tube 4 also provides part of the elastic force. When the external force acting on the water outlet head 6 is removed, the spring 5 and the spiral tube 4 jointly drive the water outlet head 6 to move onto the bushing 21.

[0028] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
