[0041] Finally, it should be noted that the motor 79, heating ring 719 and other components involved in the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0042] In the specific use of this embodiment, when it is necessary to extract and concentrate the cosmetic raw materials, first open the valve 11 on the outer wall of the tube body of the feed funnel 8, tightly sleeve the ventilation pipe of the external vacuum pump with the vacuum pipe 10, tightly sleeve the water outlet pipe of the external cold water circulation device with the water inlet end of the condenser 5, and tightly sleeve the water inlet pipe of the external cold water circulation device with the water outlet end of the condenser 5. Then, add a proper amount of cosmetic raw materials to the inside of the distillation cylinder 2 through the feed funnel 8. After the addition is completed, close the valve 11 on the outer wall of the tube body of the feed funnel 8, then open the valve 11 on the outer wall of the vacuum pipe 10 and start the external vacuum pump, so that the air inside the distillation cylinder 2 can be extracted. After the extraction is completed, close the external vacuum pump and close the valve 11 on the outer wall of the vacuum pipe 10 through the external PLC;

[0043] Subsequently, the motor 79 is started by an external PLC, and the output shaft of the motor 79 rotates to drive the rotating shaft 710 coaxially connected thereto to rotate, and the rotation of the rotating shaft 710 drives the gear 78 on the same side coaxially fixed thereto to rotate, and the rotation of the gear 78 drives another gear 78 meshing therewith to rotate, and the rotation of the other gear 78 drives the rotating rod 77 coaxially fixed thereto to rotate, and the rotation of the rotating rod 77 drives the rotating column 72 coaxially fixed thereto to rotate, and the rotation of the rotating column 72 drives the cylindrical cam 74 and the roller 73 coaxially fixed thereto to rotate, and the rotation of the roller 73 indirectly drives the two brush plates 76 to rotate, and the rotation of the two brush plates 76 can clean the inner bottom wall of the distillation cylinder 2, and the rotation of the cylindrical cam 74 drives the slide groove on its circumferential outer wall to rotate, and the rotation of the cylindrical cam 74 drives The sliding column 713 that is slidably connected to the sliding groove on its outer wall moves, and the sliding column 713 moves under the guidance of the moving rod 712, the guide block 718 and the guide groove on the front surface of the vertical plate end of the vertical plate 71. The connecting rod 714 moves to drive the two connecting rods 714 fixed thereto to move, and the movement of the connecting rod 714 drives the movement of the fixed rod 715 fixed thereto, and the movement of the fixed rod 715 drives the movement of the moving ring 716 fixed thereto, and the movement of the moving ring 716 drives the movement of the heating ring 719 fixed thereto. When the heating ring 719 moves to the inside of the distillation cylinder 2 near the bottom, the motor 79 is turned off by the external PLC, and then the external cold water circulation device and the heating ring 719 are started by the external PLC, so that the distillation of the cosmetic raw materials can be carried out.

[0044] When it is necessary to clean the inner wall of the distillation cylinder 2, first open the valve 11 on the outer wall of the tube body of the feed funnel 8, then add an appropriate amount of clean water into the distillation cylinder 2 through the feed funnel 8, and then start the motor 79 through the external PLC. As described above, the output shaft of the motor 79 rotates to drive the moving ring 716 to move. Because the slide groove on the outer wall of the cylindrical cam 74 is spiral, the cylindrical cam 74 can make the slide column 713 do linear reciprocating motion in the vertical direction during rotation, and then indirectly make the brush ring 717 do linear reciprocating motion inside the distillation cylinder 2. The brush ring 717 can clean the inner wall of the distillation cylinder 2 during the linear reciprocating motion inside the distillation cylinder 2. After cleaning for a period of time, turn off the motor 79 through the external PLC, and then tightly connect the collection pipe of the external waste liquid collection device with the discharge pipe 9. By opening the valve 11 on the outer wall of the discharge pipe 9, the waste liquid inside the distillation cylinder can be discharged.
