[0022] Reference Figures 1 to 5The invention discloses a concealed basin pull-out faucet, comprising a box body 1, a water channel 2 and a flow control valve 3 installed in the box body 1, a water outlet of the water channel 2 being located inside the box body 1, and a water outlet hose 5 being connected to the water outlet hose 5 through a joint 4 outside the water outlet, the water outlet hose 5 being wound in the annular groove 7 of the rotating seat 6, and the other end of the water outlet hose 5 extending out of the box body 1 being connected to the water outlet pull-out head 8. Since the water outlet hose 5 connected to the pull-out head 8 is wound in the annular groove 7 of the rotating seat 6, when people pull the pull-out head, the rotating seat 6 will rotate and release the water outlet hose 5, so that the pull-out head 8 can be moved to a suitable position, which is convenient for people to wash their hair or face; when it is not needed, the water outlet hose 5 can be pushed back to the rotating seat 6 in the box body 1. Changing the previous fixed water outlet nozzle to a movable pull-out head can greatly reduce the restrictions on the use position of the faucet, which greatly facilitates people's use. The utility model can be conveniently used as long as a rotating seat, a water outlet hose and a pull-out head are arranged in the box body, and the structure is simple and worthy of promotion.

[0023] The middle part of the rotating seat 6 is provided with a circular hole 9, and the circular hole 9 is sleeved around the water outlet of the water channel 2, so that the rotating seat 6 can rotate around the water outlet of the water channel 2. In addition, a groove surface of the rotating seat 6 is provided with a notch 10 connected to the annular groove 7 along the axial direction. The connector 4 is an elbow, one end of which is connected to the water outlet, and the other end is located at the notch 10 and connected to the water outlet hose 5. The water outlet hose 5 is wound in the annular groove 7 from the notch 10. Such a design can avoid the defects of the water outlet hose 5 or the connector 4 crossing the groove surface of the rotating seat 6 to allow the water outlet hose 5 to be wound in the annular groove 7, which causes the structure to be bloated and hinders the rotation of the rotating seat 7. In addition, in order to further facilitate the rotation of the rotating seat 6 to release or collect the water outlet hose 5, the opening direction of the notch 10 can be set to the tangential direction of the circumference, so as to further reduce the friction of the water outlet hose during the movement process, and further facilitate people's use. Furthermore, in order to prevent the joint 4 from leaking due to rotation, the joint 4 is fixed to the water outlet of the waterway 2 by a pressing sheet 30, which can prevent the joint 4 from rotating and detaching from the water outlet of the waterway.

[0024] In addition, an annular groove 11 is provided at the bottom of the rotating seat 6, and a spring sheet 12 is installed in the annular groove 11 to move with the rotation of the rotating seat 6. When people pull the pull-out head 8, the rotating seat 6 rotates, and the spring sheet 12 is deformed; when people put the pull-out head 8 back to its original position after use, the spring sheet 12 is reset, thereby driving the rotating seat 6 to rotate in the opposite direction, so that the water outlet hose 5 is automatically collected back into the annular groove 7 of the rotating seat 6, further facilitating people's use.

[0025] In order to further ensure that the spring sheet works effectively and prevent it from moving and deforming when the rotating seat 6 rotates, the spring sheet 12 is installed in an annular groove 11 in a circular shape, and one end of the spring sheet is mounted on the protrusion 14 of the rotating seat 6 through a ring 13.

[0026] In addition, the water outlet hose 5 passes through the guide seat 15 and the pull head fixing seat 16 and is connected to the pull head 8. The water outlet structure of the utility model adopts a three-stage design, which is convenient for production and assembly. Moreover, the guide seat 15 is fixed to the two bosses 18 of the box body base by screws, and the lower end surface 17 of the guide seat 15 is trumpet-shaped. Such a guide seat 15 is convenient for the water outlet hose 5 to pass through, and can effectively reduce the friction of the water outlet hose 5 during the movement process, further facilitating use and reducing wear.

[0027] In order to prevent the pull-out head fixing seat 16 from escaping from the guide seat 15 , one end of the pull-out head fixing seat 16 is sleeved on the guide seat 15 and fixed by a screw.

[0028] In addition, a connecting sleeve 20 is fixed at the end of the pull-out head 8, and an elastic protrusion 21 is provided on the connecting sleeve 20 to be clamped in the through hole of the fixing seat 16, and the end face of the elastic protrusion 21 is in the shape of an inclined plane with a high front and a low back. The surface of the connecting sleeve 20 is also provided with an arc-shaped protrusion 22, and a bayonet 23 is provided on the fixing seat 16 for the arc-shaped protrusion 22 to be inserted into, and the bayonet 23 and the elastic protrusion 21 are located on the same straight line. The conical end of the pull-out head can facilitate the insertion of the pull-out head 8 into the fixing seat 16; when the elastic protrusion 21 is inserted into the through hole of the fixing seat 16, the pull-out head 8 can be firmly connected to the fixing seat 16. In addition, the end face of the elastic protrusion 21 is in the shape of an inclined plane with a higher front and a lower back, which can further facilitate the insertion of the pull-out head 8 into the fixing seat 16, and at the same time effectively prevent the pull-out head 8 from falling out of the fixing seat 16; by pressing the arc-shaped protrusion 22, the elastic protrusion 21 can be pulled out of the through hole of the fixing seat 16, which is convenient for taking out the pull-out head 8; and the arc-shaped protrusion 22 on the surface of the pull-out head connecting sleeve 20 can reduce the friction between the pull-out head 8 and the fixing seat 16 during relative rotation. When the arc-shaped protrusion 22 sinks into the bayonet 23, the elastic protrusion 21 also sinks into the through hole of the fixing seat 16, thereby realizing the reconnection of the pull-out head 8 and the fixing seat 16.

[0029] In order to further facilitate people's use, the water outlet pull head 8 is provided with two shapes of water outlet nozzles, a switching button 24 for controlling the shape of water outlet, and a water outlet switch button 25. The two shapes of water outlet nozzles are respectively a bubble round water outlet nozzle 26 and a square water outlet nozzle 27. In addition to being controlled by the flow control valve 3 in the box body, the water outlet of the water outlet pull head 8 can also be controlled by the handheld pull head 8 water outlet switch button 25, and the water outlet style can be operated by the switching button 24.
