[0036] Working principle or structural principle: When moisturizing the face, first install the liquid-filling syringe 12 between the fixed splints 16, then manually rotate the metal fixing nut 34 to move the two sets of fixed splints 16 closer to each other, and the push rod of the liquid-filling syringe 12 is clamped in the push rod fixing seat 21;

[0037] After the noise reduction air pump 11 is started, the suction end of the noise reduction air pump 11 generates negative pressure in the retractable nine-needle 3. The airflow passes through the connecting pipe of the tee 31 and is discharged from the air outlet 35. When the retractable nine-needle 3 contacts the face, the negative pressure sucks the facial muscles onto the needle outlet 27, making it convenient to hydrate the face at close range and enhancing the hydration effect.

[0038] When the front motor 17 is started, the output end of the front motor 17 drives the needle outlet screw rod 32 to rotate, and the needle outlet screw rod 32 drives the metal sliding plate 22 to move through the threaded action with one group of U-shaped sliders 40, thereby driving the nine-needle fixing bracket 24 to move, so that the liquid-filling syringe 12 can move along its own axial direction. When the liquid-filling syringe 12 moves in the direction close to the retractable nine-needle 3, the liquid outlet end of the liquid-filling syringe 12 can be inserted into the syringe fixing interface 26, so that the liquid in the liquid-filling syringe 12 can be injected into the retractable nine-needle 3. When the rear motor 18 is started, the output end of the rear motor 18 drives the liquid-pushing screw rod 29 to rotate, and the liquid-pushing screw rod 29 drives the push rod fixing seat 21 to move through another group of U-shaped sliders 40, thereby pushing the retractable end of the liquid-filling syringe 12 to move, pushing the liquid in the liquid-filling syringe 12 into the retractable nine-needle 3, and the liquid is discharged from the needle outlet hole 27 to complete the hydration of the face;

[0039] When the output end of the front motor 17 drives the metal sliding plate 22 to move, since the sensor circuit board 39 is installed on the screw fixing seat 33, and the screw fixing seat 33 is installed on the metal sliding plate 22, the sensor circuit board 39 moves with the metal sliding plate 22. When the U-shaped slider 40 connected to the liquid pushing screw 29 moves forward to the limit distance, the sensor circuit board 39 approaches the small magnet 36, thereby generating electromagnetic induction. The electromagnetic induction signal causes the front motor 17 to stop continuing to output, thereby playing a role in limiting protection for the components in the equipment. When the U-shaped slider 40 connected to the liquid pushing screw 29 moves backward to the limit distance, the sensor at the rear end of the circuit board 4 approaches the small magnet 36, thereby generating electromagnetic induction, and the electromagnetic induction signal causes the rear motor 18 to stop continuing to output, thereby playing a role in limiting protection for the components in the equipment. The screw fixing seat 33 plays the role of fixing the front sensor and the rear liquid pushing screw.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
