[0028] An adjusting nut 44 is threadedly connected to the lower end of the right telescopic rod 37 .

[0029] The left end of the liquid separation hole 35 is inclined downward.

[0030] The fixing structure includes a plurality of hidden holes 45 evenly arranged from top to bottom on the right side wall of the fixing sleeve 10; a screw hole 46 that penetrates the internal space of the fixing sleeve 10 is provided at the bottom of the hidden hole 45; a matching fastening screw 47 is screwed into the screw hole 46, and the left end of the fastening screw 47 is pressed on the outer wall of the faucet body 2; the head of the fastening screw 47 is located in the hidden hole 45, and a fastening spacing 48 is provided between the head of the fastening screw 47 and the bottom of the hidden hole 45; the upper end of the faucet body 2 is screwed to the lower end of the right part of the faucet neck 5.

[0031] The motor 13 is fixed to the motor mounting plate 11 by a plurality of evenly distributed fixing screws 49 .

[0032] The method of using the utility model is as follows:

[0033] In order to facilitate hiding the wires of the motor 13, a first wire threading hole 50 opposite to the motor 13 may be set on the left side wall of the fixing sleeve 10, and then a second wire threading hole 51 intersecting the first wire threading hole 50 may be set on the lower surface of the fixing sleeve 10, and then a third wire threading hole 52 corresponding to the position of the second wire threading hole 51 may be set on the left side wall of the upper end of the faucet seat 1, and then the wires of the motor 13 are passed through the first wire threading hole 50, the second wire threading hole 51, and the third wire threading hole 52 in sequence and penetrated into the faucet seat 1, and finally can be led out of the faucet seat 1 through the lead hole 8. This wiring method is not only convenient for hiding the wires of the motor 13, but also conducive to connecting the motor 13 to the controller through the wires. At the same time, the wires of the infrared sensor 4 can also be connected to the controller, and the motor 13 and the infrared sensor 4 are both controlled by the controller inside the vegetable basin faucet. The controller is an existing integrated circuit that can effectively receive information and issue corresponding instructions.

[0034] Before using the kitchen sink faucet, the back of the hand can be used to push the lower end of the right telescopic rod 37 upwards. As the right telescopic rod 37 drives the movable plate 38 upwards, the hand sanitizer originally located between the movable plate 38 and the sealing cover 40 will fall into the space between the lower surface of the movable plate 38 and the upper surface of the limit head 34 through the liquid through hole 39 under the action of gravity. During the upward movement of the movable plate 38, the movable plate 38 will compress the right spring 42 upwards, and the right spring 42 will generate elasticity. Therefore, when the user no longer pushes the lower end of the right telescopic rod 37 upwards, the movable plate 38 will move downward and reset under the elastic action of the right spring 42, thereby squeezing a portion of the hand sanitizer located between the lower surface of the movable plate 38 and the upper surface of the limit head 34 into the liquid separation hole 35, so that the hand sanitizer enters the space above the water-blocking plate 22 through the liquid separation hole 35.

[0035] When the kitchen sink faucet needs to be used, the user can put his hand in front of the infrared sensor 4. At this time, the infrared sensor 4 will immediately feedback the information sensed by the user to the controller, and the controller will immediately start the solenoid valve of the kitchen sink faucet. The solenoid valve will open the valve core of the kitchen sink faucet, thereby opening the kitchen sink faucet. At this time, water will flow into the pull-out pipe 7 and finally be sprayed out through the faucet nozzle 6 for use.

[0036] The water flow sprayed from the faucet spout 6 will spray into the mixing hole 21, and the water flow entering the mixing hole 21 will push the opening and closing plate 29 downward by its own water pressure, and compress the left spring 31 downward. As the opening and closing plate 29 moves downward, the water flow above the water-blocking plate 22 will flow into the space below the opening and closing plate 29 through the opening and closing hole 23, the gap between the lower surface of the water-blocking plate 22 and the upper surface of the opening and closing plate 29, and the water-passing gap 30 in sequence, and finally be discharged to the outside through the drain hole 27 for use. When the water flow rushes into the mixing hole 21, it will directly use its own impact force to break up the hand soap on the upper surface of the water-blocking plate 22, and then in the process of flowing from the opening and closing hole 23 to the drain hole 27, the hand soap will be fully mixed in the water flow, thereby ensuring that the water flow sprayed from the drain hole 27 is a water flow evenly mixed with hand soap. The user only needs to place his hands under the drain hole 27 to allow his hands to be showered with the water mixed with hand sanitizer. As the user's hands leave the sensing range of the infrared sensor 4, the controller will close the solenoid valve and start the motor 13 at the same time. When the motor 13 is started, the motor shaft of the motor 13 will drive the screw 18 to rotate, and the screw 18 is screwed to the screw hole 16, and the guide arm 12 matches the square hole 20. Therefore, when the screw 18 rotates, the rotational force is converted into a force for moving the mixer 14, thereby realizing the rightward movement of the mixer 14. As the mixer 14 moves to the right, the mixer 14 is no longer under the faucet mouth 6. At this time, the dish basin faucet can be started again by sensing the infrared sensor 4, and the faucet mouth 6 directly sprays clean water to rinse the hand sanitizer on the user's hands.

[0037] The specific water discharge steps of the kitchen sink faucet are as follows: the infrared sensor 4 senses for the first time, the faucet mouth 6 discharges water and sprays it into the mixing hole 21, the infrared sensor 4 is closed for the first time, the motor 13 is started, and the liquid mixer 14 moves to the right and away from under the faucet mouth 6; when the infrared sensor 4 senses for the second time, the faucet mouth 6 sprays water, when the infrared sensor 4 is closed for the second time, the motor 13 is started again, the liquid mixer 14 moves to the left and resets, and is again under the faucet mouth 6; when the infrared sensor 4 senses for the third time, the faucet mouth 6 discharges water and sprays it into the mixing hole 21 again, the infrared sensor 4 is closed for the third time, the motor 13 is started again, and the liquid mixer 14 moves to the right and away from under the faucet mouth 6 again; a cycle is formed in this way.

[0038] In summary, the utility model can deliver the hand sanitizer in the liquid storage hole 33 to the liquid mixing hole 21, and then introduce the water flow sprayed from the faucet nozzle 6 into the liquid mixing hole 21, so that the hand sanitizer is fully mixed in the water flow, ensuring that the user can directly use the hand sanitizer without touching the kitchen sink faucet, thereby being able to fully wash away the grease on the user's hands, and finally the grease on the user's hands can be rinsed clean with clean water, ensuring the cleaning quality and avoiding the situation where the user still causes pollution after cleaning.

[0039] The diameter of the opening and closing hole 23 gradually decreases from top to bottom, so as to quickly guide the water flow entering the mixing hole 21 to the bottom of the water-blocking plate 22, so as to quickly discharge the water flow to the outside.

[0040] The outer wall of the opening and closing plate 29 is provided with a water-guiding cone 32 which is narrow at the top and wide at the bottom. The existence of the water-guiding cone 32 can quickly guide the water flow when it flows under the water-blocking plate 22, further improving the efficiency of discharging water from the drainage hole 27.

[0041] A guide rod 43 located inside the right spring 42 is provided at the center of the lower surface of the sealing cover 40 . The existence of the guide rod 43 can effectively ensure the stability of the right spring 42 when it is compressed or expanded.

[0042] An adjusting nut 44 is screwed to the lower end of the right telescopic rod 37 . The existence of the adjusting nut 44 can effectively limit the upward movement of the right telescopic rod 37 . Therefore, the upward movement of the right telescopic rod 37 can be adjusted by simply changing the position of the adjusting nut 44 .

[0043] The left end of the liquid separation hole 35 is tilted downward. This structural arrangement facilitates the hand washing liquid to flow into the liquid storage hole 33 in the shortest possible time after entering the liquid separation hole 35 from the liquid storage hole 33 .

[0044] The fixing structure includes a plurality of hidden holes 45 evenly arranged from top to bottom on the right side wall of the fixing sleeve 10, a screw hole 46 which is connected to the internal space of the fixing sleeve 10 is arranged at the bottom of the hidden hole 45, a fastening screw 47 which matches the screw hole 46 is screwed in, the left end of the fastening screw 47 is pressed on the outer wall of the faucet body 2, the head of the fastening screw 47 is located in the hidden hole 45, and a fastening spacing 48 is provided between the head of the fastening screw 47 and the bottom of the hidden hole 45, the upper end of the faucet body 2 is screwed to the lower end of the right part of the faucet neck 5, this fixing method facilitates the disassembly and assembly of the fixing sleeve 10, thereby facilitating the maintenance and replacement of other components.

[0045] The motor 13 is fixed to the motor mounting seat 11 by a plurality of evenly distributed fixing screws 49 . This fixing method facilitates the disassembly and assembly of the motor 13 , thereby facilitating the maintenance and replacement of the motor 13 .
