[0030] See also Figure 1-Figure 7 A pull-out faucet comprises a faucet body 1, a pull-out tube 2, a magnetic component and a pull-out guide rail component 4.

[0031] The faucet body 1 includes a body portion 11 and a mounting portion 12. The body portion 11 includes a tee 111, a water outlet elbow 112 and a valve core assembly 113. The tee 111 is disposed on a countertop, the water outlet elbow 112 is connected to the upper end of the tee 111, the valve core assembly 113 is connected to the side end of the tee 111, and the water outlet elbow 112 can rotate relative to the upper end of the tee 111 to change the position of its end.

[0032] The mounting portion 12 is tubular and is disposed at the lower end of the three-way pipe 111. The mounting portion 12 can pass through the mounting hole of the countertop from top to bottom to correspond to the bottom of the countertop. The mounting portion 12 can be a threaded tube, and a screw seat can be screwed on the threaded tube, and the screw seat can be pressed against the lower side of the countertop. Alternatively, the mounting portion 12 can also be other forms of structure, as long as the faucet body 1 can be fixed on the countertop.

[0033] The pull-out tube 2 is pullably disposed on the faucet body 1, the pull-out guide rail component 4 is detachably disposed on the faucet body 1, the pull-out guide rail component 4 includes a pull-out channel 41, and the pull-out tube 2 passes through the pull-out channel 41. The magnetic sensing component includes a magnetic induction switch 31 and a magnetic component 32, the magnetic component 32 is disposed on the pull-out tube 2, the magnetic induction switch 31 is disposed on the pull-out guide rail component 4, the magnetic induction switch 31 is close to or disposed on the inner wall of the pull-out channel 41, and when the pull-out tube 2 moves in the pull-out channel 41, the magnetic component 32 corresponds to or staggers the magnetic induction switch 31.

[0034] An installation channel 121 is formed inside the installation portion 12, and the installation channel 121 is connected to the three-way pipe 111. The hot water pipe and the cold water pipe are connected to the valve core assembly 113 through the installation channel 121 respectively. The valve core assembly 113 receives hot water and cold water from the hot water pipe and the cold water pipe to form mixed water. One end of the pull-out tube 2 is connected to the valve core assembly 113, and the mixed water passes into the pull-out tube 2. The pull-out tube 2 first passes through the installation channel 121, then passes through the pull-out channel 41, and extends through the three-way pipe 111 and the water outlet elbow 112 until it passes through the end of the water outlet elbow 112. The end of the pull-out tube 2 is connected to a water outlet head 5, and the mixed water can be sprayed out from the water outlet head 5.

[0035] The pull-out guide rail component 4 can be detachably arranged on the mounting portion 12, and the pull-out guide rail component 4 is arranged inside the mounting portion 12. Specifically, the pull-out guide rail component 4 is arranged in the mounting channel 121. The pull-out guide rail component 4 is arranged close to one side of the mounting channel 121, and a pipe penetration space 122 is formed on the other side of the mounting channel 121, and the pipe penetration space 122 is used to penetrate pipes or lines. In this embodiment, after one end of the pull-out tube 2 is connected to the valve core assembly 113, it first passes through the pipe penetration space 122, and then passes through the pull-out channel 41, until its end passes through the end of the water outlet elbow 112.

[0036] The magnetic induction switch 31 is arranged inside the pull-out guide rail component 4, and the magnetic component 32 is arranged on the pull-out tube 2. The magnetic component 32 is a magnet that is insert-molded on the pull-out tube 2. When the magnetic component 32 corresponds to the magnetic induction switch 31, the water outlet head 5 abuts against the end of the water outlet elbow 112, and when the water outlet head 5 is pulled to drive the pull-out tube 2 to move, the magnetic component 32 staggers the magnetic induction switch 31. In this embodiment, when the magnetic component 32 corresponds to the magnetic induction switch 31, the pull-out tube 2 does not discharge water, and when the magnetic component 32 staggers the magnetic induction switch 31 by a certain distance, the pull-out tube 2 discharges water.

[0037] Alternatively, when the magnetic component 32 is offset from the magnetic induction switch 31, the water outlet head 5 is against the end of the water outlet elbow 112, and when the water outlet head 5 is pulled to drive the pull-out tube 2 to move, the magnetic component 32 corresponds to the magnetic induction switch 31. In this embodiment, when the magnetic component 32 corresponds to the magnetic induction switch 31, the pull-out tube 2 discharges water, and when the magnetic component 32 is offset from the magnetic induction switch 31 by a certain distance, the pull-out tube 2 does not discharge water.

[0038] The pull-out faucet further includes a cover 6. The lower end of the pull-out guide rail component 4 is detachably connected to the cover 6, and the cover 6 and the lower end of the pull-out guide rail component 4 are snap-connected with the mounting portion 12; the cover 6 includes an opening connected to the pipe-through space 122.

The depth of the cover 6 inserted into the mounting channel 121 is relatively shallow, and the cover 6 cooperates with the pull-out guide rail component 4 to fix the pull-out guide rail component 4 on the mounting portion 12.

[0039] The drawer rail component 4 includes a mounting groove 42, and the magnetic induction switch 31 is detachably connected to the mounting groove 42. In this embodiment, the magnetic induction switch 31 is connected to the mounting groove 42 by snapping.

[0040] The pull-out tube 2 is provided with a solenoid valve 7, and the magnetic induction switch 31 is linked to the solenoid valve 7. The solenoid valve 7 can be used to control the on-off of the pull-out tube 2, and the magnetic induction switch 31 can be linked to the solenoid valve 7 to achieve the corresponding water outlet function.

[0041] The extractable faucet further includes a battery box weight 8, which is disposed on the pull-out tube 2 and supplies power to the magnetic induction switch 31 and the solenoid valve 7. The extractable faucet further includes an induction switch 9 disposed on the faucet body 1, which is linked to the solenoid valve 7 and supplies power to the induction switch 9. The battery box weight 8 can not only serve as a weight for the pull-out tube 2, but also serve as a power supply for the above-mentioned components.

[0042] During use, the user can pull the water outlet 5, so that the pull-out tube 2 is driven to make the magnetic component 32 stagger the magnetic induction switch 31, and then control the solenoid valve 7 to make the solenoid valve 7 pass water. When the user releases the water outlet 5, the pull-out tube 2 drives the water outlet 5 back to the initial position due to the action of the battery box weight 8. At this time, the magnetic component 32 corresponds to the magnetic induction switch 31, and the solenoid valve 7 cuts off the water. If the user does not want to discharge water by pulling, he can wave his hand so that the induction switch 9 senses the presence of the hand, so that the solenoid valve 7 passes water, and wave his hand again to sense the presence of the hand to cut off the water supply of the solenoid valve 7.

[0043] 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.
