[0020] The utility model will be further described in connection with the drawings and specific embodiments.

[0021] In connection with Figures 1 to 4 A slag scraping device of a full-automatic coffee machine, comprising a brewing cup assembly 3, a driving assembly and a supporting plate 1, the driving assembly drives the brewing cup assembly 3 to move, the brewing cup assembly 3 sequentially converts between a piston returning section, a powder loading position, a brewing position, a waste cake pushing section and a slag scraping section, the piston 30 is pushed out while the brewing cup assembly 3 is engaged with the brewing head 2, then powder loading is performed, after powder loading is completed, the driving assembly drives the brewing cup assembly 3 to ascend and engage with the brewing head 2 again to perform brewing, after brewing is completed, the driving assembly drives the brewing cup assembly 3 to move downward to push waste cake, after waste cake pushing is completed, the driving assembly drives the brewing cup assembly 3 to move upward into the slag scraping section.

[0022] In connection with Figure 5The brewing cup assembly 3 is equipped with a scraping mechanism 5, and the support plate 1 is equipped with a contact device 4. The scraping mechanism 5 includes a scraping plate and a scraping plate return spring. The scraping plate includes a scraping surface 53, a scraping plate rotating shaft 52, and a driven part 51. The scraping plate return spring is disposed inside the scraping plate rotating shaft 52, and the driven part 51 is spiral in shape. The scraping plate is located at the mouth of the brewing cup assembly 3 and can rotate or move relative to the mouth of the cup. The contact device 4 includes a contact block 41, a contact block rotating shaft 42, and a contact block return spring 44. The contact block 41 rotates around the contact block rotating shaft 42. When the contact block 41 rotates, a pad 43 is provided on the part that contacts the support plate 1. The pad 43 is used to cushion the contact block 41 during contact with the support plate 1.

[0023] Combination Figure 6 When the driving component drives the brewing cup assembly 3 to rise and scrape the residue, the contact block 41 contacts the driven part 51. As the driving component continues to drive the brewing cup assembly 3 to rise, the contact block 41 is blocked by the support plate 1 and cannot rotate or move. The contact block 41 presses the driven part 51 so that the driven part 51 drives the scraper plate to rotate around the scraper plate shaft 52. Then the scraper plate reset spring resets the scraper plate.

[0024] Combination Figure 7 The upper surface of the touch block 41 is provided with an inclined surface 411, which makes it easier for the touch block 41 to be pushed away by the driven part 51. The inclined surface 411 can be provided separately on the upper surface of the touch block 41 or the lower surface of the driven part 51, or it can be provided on both the upper surface of the touch block 41 and the lower surface of the driven part 51. When the driving component drives the brewing cup assembly 3 to move downward, the driven part 51 contacts the inclined surface 411. The cup surface of the brewing cup assembly 3 is provided with a stop block 54, which is located at a position that can prevent the scraper from rotating in the opposite direction when the driven part 51 presses the inclined surface 411.

[0025] Combination Figure 8 As the drive assembly continues to drive the brewing cup assembly 3 to descend, the driven part 51 presses the inclined surface 411 to make the contact block 41 rotate around the contact block pivot 42 until the contact block 41 is displaced from the driven part 51. At this time, the scraper is limited by the stop block 54 and cannot rotate or move. Subsequently, the contact block 41 is reset by the contact block reset spring 44.
