[0033] Pull-out guide rail 5 is arranged in installation pipe 12, pull-out guide rail 5 includes a pull-out channel 51, pull-out pipe 2 passes through pull-out channel 51.The upper end of pull-out guide rail 5 can be fixedly connected with faucet seat body 11, and the lower end of pull-out guide rail 5 is exposed outside the lower end of installation pipe 12.Pull-out guide rail 5 is a tubular component, pull-out channel 51 is formed at the middle part of pull-out guide rail 5, and the outer side wall of pull-out guide rail 5 also forms a protrusion 52, which abuts against the lower end of installation pipe 12 to limit the upward movement of pull-out guide rail 5.During installation, pull-out guide rail 5 is attached in installation pipe 12 from bottom to top, and the upper end of pull-out guide rail 5 can be connected with faucet seat body 11 by buckle connection.The end of pull-out pipe 2 passes through pull-out channel 51 from bottom to top and passes out from water outlet elbow 113, and the end of pull-out pipe 2 is connected with a water outlet head 21, which can abut against the end of water outlet elbow 113, and the user can directly pull out water outlet head 21 when using, so that it faces the direction to be washed.

[0034] The magnetic induction component includes a magnetic induction switch 31 and a magnetic component 32, the magnetic component 32 is arranged on the pull-out pipe 2, the magnetic induction switch 31 is arranged on the pull-out rail 5, the magnetic induction switch 31 is close to or arranged on the inner wall of the pull-out channel 51, when the pull-out pipe 2 moves in the pull-out channel 51, the magnetic component 32 corresponds to or offsets the magnetic induction switch 31. When the water outlet head 21 abuts against the end of the water outlet elbow 113, the magnetic component 32 corresponds to the magnetic induction switch 31, at this time, the pull-out pipe 2 is controlled and cannot be watered. When the pull-out pipe 2 is pulled, because the magnetic component 32 offsets the magnetic induction switch 31, at this time, the pull-out pipe 2 is controlled to be watered.

[0035] In order to realize the cooperation with other electronic components (such as an induction window), the magnetic induction switch 31 needs to be connected with these components through wires. These wires are often exposed outside the pull-out rail 5. The exposed design of the wires can easily cause a series of problems in actual use.

The above structure can play a role in protecting the bending section 611. The protective sleeve is detachably arranged at the lower end of the mounting pipe, effectively shielding the exposed bending section wire. This design significantly reduces the risk of the wire being affected by external environmental factors (such as collision, pulling or abrasion), prolonging the service life of the wire. At the same time, the shielding effect of the protective sleeve on the wire can prevent the invasion of water vapor, oil stains and other substances, further improving the durability and stability of the faucet.
