[0025] The extraction assembly 4 includes a circular top plate 5, which is fixedly installed on the top of the outer shell 1. A feed pipe 6 is fixedly installed through the inside of the circular top plate 5. A cylinder 7 is fixedly installed at the bottom of the circular top plate 5, and the bottom of the feed pipe 6 extends to the top of the inside of the cylinder 7. A hemispherical filter cover 8 is fixedly installed at the bottom of the cylinder 7. A rotating tube 9 is rotatably installed at the center of the bottom end of the circular top plate 5. A positioning bearing 20 is rotatably installed on the outside of the rotating tube 9, and the positioning bearing 20 is fixedly installed at the center of the bottom end of the circular top plate 5. A positioning strip 21 is rotatably installed below the positioning bearing 20 and on the outside of the rotating tube 9, and both ends of the positioning strip 21 are fixedly connected to the inner wall of the cylinder 7. A movable tube 10 is fixedly installed through the inside of the bottom end of the rotating tube 9, and the inside of the movable tube 10 is connected to the inside of the rotating tube 9. Water outlets 11 are evenly opened at the bottom of the movable tube 10. A shaft 12 is fixedly installed at the bottom of the rotating tube 9, and the shaft 12 is fixedly installed on the outside of the rotating tube 9. Agitator bars 13 are uniformly fixedly installed on the side, and the agitator bars 13 have an open structure inside. A positioning sleeve 22 is rotatably installed on the outer side of the top of the shaft 12. Four positioning rods 23 are symmetrically fixedly installed on the outer side of the positioning sleeve 22, and the ends of the four positioning rods 23 away from the positioning sleeve 22 are fixedly connected to the inner wall of the cylinder 7. A shell 14 is fixedly installed on the top of the circular top plate 5. A rotating joint 15 is fixedly installed on the top of the inner side of the shell 14, and the top of the rotating tube 9 extends into the inner side of the shell 14 and is rotatably connected to the bottom of the rotating joint 15. A water inlet valve 16 is fixedly installed on the top of the shell 14, and the bottom of the water inlet valve 16 communicates with the top of the rotating joint 15. A drive motor 17 is fixedly installed on the inner wall of the shell 14. A drive bevel gear 18 is fixedly installed on the output shaft of the drive motor 17. A transmission bevel gear 19 is meshed on the outer side of the drive bevel gear 18, and the transmission bevel gear 19 is fixedly installed on the outer side of the rotating tube 9.

[0026] During use, the interaction of the outer shell 1, the bottom hopper 2, the liquid outlet valve 3, and the extraction component 4 allows the extraction mechanism of the unmanned self-service coffee machine to ensure that hot water fully contacts the coffee powder, improving extraction efficiency and thus achieving better practicality. Furthermore, the interaction of the mounting base 24 and the fixed mounting hole 25 facilitates the fixed installation of the entire mechanism during use, making operation convenient while ensuring the stability of the entire mechanism.

[0027] Working Principle: During operation, the mounting base 24 is first fixed using bolts that match the diameter of the mounting hole 25, thus securing the entire mechanism. Then, the top of the feed pipe 6 is connected to the coffee powder conveying pipe, and the top of the water inlet valve 16 is connected to the hot water conveying pipe. During use, coffee powder is conveyed through the feed pipe 6 to the inside of the cylinder 7 via the coffee powder conveying pipe. Under gravity, the coffee powder concentrates inside the hemispherical filter hood 8. Then, the water inlet valve 16 is opened, and hot water is conveyed through the water inlet valve 16, the rotating joint 15, and the rotating pipe 9 to the inside of the movable pipe 10. Simultaneously, the drive motor 17 is started, driving the drive bevel gear 18 to rotate. The drive bevel gear 18 drives the transmission bevel gear 19 to rotate, and the transmission bevel gear 19 drives the rotating pipe 9 inside the positioning bearing 20 and the positioning strip 21. Rotation ensures better stability of the rotating tube 9 during rotation. Simultaneously, the rotating tube 9 drives the internal movable tube 10 to rotate. During rotation, the movable tube 10 sprays hot water through the outlet 11 at its bottom, ensuring even distribution of hot water onto the coffee powder. At the same time, the rotating tube 9 drives the shaft 12 to rotate inside the positioning sleeve 22. The shaft 12 then drives the outer stirring bar 13 to rotate, thoroughly mixing the coffee powder and hot water, ensuring complete contact. The well-stirred coffee liquid is then extracted and filtered under the action of the hemispherical filter 8. The extracted coffee liquid flows downwards into the bottom hopper 2. Opening the outlet valve 3 allows the extracted coffee liquid to be output. The thorough contact between the hot water and coffee powder improves extraction efficiency, thus enhancing practicality.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
