High-penetration atomizing beauty instrument and rotating mechanism thereof

A rotating mechanism adapted to be used with a high-penetration atomizing beauty instrument, comprising an air-liquid tube shaft, a joint and a liquid suction tube, wherein

• a slot is provided at a middle position of the air-liquid tube shaft, and a length direction of the slot is perpendicular to an axial direction of the air-liquid tube shaft;
• a linear through hole is provided at a bottom of the joint and the air-liquid tube shaft penetrates the linear through hole at the bottom of the joint, and the air-liquid tube shaft and the joint are rotatable with each other;
• and
• the liquid suction tube is fixed in an inner hole of the joint, and one end of the liquid suction tube is inserted into the slot, and movable within 90° along a circumferential direction of the air-liquid tube shaft;
• a length of an outer surface of the slot is a sum of a quarter of a circumference of the air-liquid tube shaft and an outer diameter of the liquid suction tube;
• and
• a maximum rotation angle between the joint and the air-liquid tube shaft is restricted to 90°.
