[0064] The toner cartridge bushing 064 on the left side of the toner cartridge 065 passes through the guide slot 0211 on the toner cartridge guide rail 021 and extends into the first toner cartridge track 0811, enabling the toner cartridge 065 to move up and down and swing along the first toner cartridge track 0811. The slag pushing rod guide rail shaft 0610 on the left side of the slag pushing rod 0611 is movably connected to the first slag pushing rod guide rail shaft track 0812, enabling the slag pushing rod 0611 to move up and down along the first slag pushing rod guide rail shaft track 0812 for slag pushing. The guiding slider 023 on the left side of the toner cartridge guide rail bracket 022 is movably connected to the first toner cartridge guide rail bracket assembly track 0813 to guide and limit the lifting movement of the toner cartridge guide rail bracket 022.

[0065] As Figure 5 shown, the respective points where the first toner cartridge track 0811 bends from top to bottom are the powder pressing top end A1, the swinging starting point B1 of the toner cartridge 065, the outermost swinging point C1 of the toner cartridge 065, the slag scraping starting point D1 of the slag scraping rod 061, and the slag scraping ending point E1 of the slag scraping rod 061. The points of the first slag pushing rod guide rail shaft track 0812 from top to bottom are the highest slag pushing point F1 and the lowest slag pushing point G1 of the slag pushing rod guide rail shaft 0610. The points of the first toner cartridge guide rail bracket track 0813 from top to bottom are the highest bracket point H1 and the lowest bracket point I1 of the toner cartridge guide rail bracket 022.

[0066] The movement track positions of the first powder box track 0811 are as follows: from the top of the powder pressing A1 to the starting point of swinging B1 is the track position for realizing the powder pressing and coffee brewing of the powder box assembly 06; from the starting point of swinging B1 to the outermost point of swinging C1 is the track position for realizing the swinging and outward movement of the powder box assembly 06 to receive coffee powder; from the outermost point of swinging C1 to the starting point of slag scraping D1 is the track position for realizing the slag topping of the powder box assembly 06; from the starting point of slag scraping D1 to the end point of slag scraping E1 is the track position for realizing the slag scraping of the powder box assembly 06; from the highest point of slag topping F1 to the lowest point of slag topping G1 is the track position for realizing the slag topping track of the slag topping rod guide rail shaft 0610 and the slag topping rod 0611; from the highest point of the bracket H1 to the lowest point of the bracket I1 is the track position for realizing the indirect or direct driving of the powder box assembly 06 to move by the powder box guide rail bracket 022.

[0067] The left snap 083 is rotatably arranged at the G1 position at the bottom end of the first slag topping rod guide rail track 0812 through the left snap torsion spring 082, so that the left snap 083 can extend into or withdraw from the first slag topping rod guide rail track 0812, and the left snap cover 084 is arranged on the left side plate 081 inside the left snap 083.

[0068] When the slag topping rod guide rail shaft 0610 on the slag topping rod 0611 moves to the lowest point of slag topping G1, the left snap 083 pops out and clamps the slag topping rod guide rail shaft 0610. When the powder box 065 moves from the starting point of slag scraping D1 to the outermost point of swinging C1 of the powder box, the slag topping rod 0611 is only affected by the frictional force between the powder box 065 and the slag topping rod seal ring 069 and the locking force between the snap 083 and the slag topping rod guide rail shaft 0610 along the axial direction. When the frictional force between the powder box 065 and the slag topping rod seal ring 069 is less than the locking force between the snap 083 and the slag topping rod guide rail shaft 0610, the snap 083 will first clamp the slag topping rod guide rail shaft 0610 at the G1 position to pull the slag topping rod 0611, causing relative movement between the slag topping rod 0611 and the powder box 065, so as to open the powder receiving cavity in the powder box 065. When the powder box 065 runs to the C1 position, the powder receiving cavity reaches the maximum volume. When the powder box 065 continues to move from C1 to the starting point of swinging B1 of the powder box, the slag topping rod 0611 is affected by the pulling force of the powder box 065 on the slag topping rod 0611 and the locking force of the snap 083 on the slag topping rod guide rail shaft 0610 along the axial direction. When the pulling force of the powder box 065 on the slag topping rod 0611 is greater than the locking force of the snap 083 on the slag topping rod guide rail shaft 0610, the slag topping rod guide rail shaft 0610 contacts along the inclined surface at the bottom of the left snap 083, causing the left snap 083 to rotate outward to withdraw from the first slag topping guide rail track 0812, facilitating the upward movement of the slag topping rod guide rail shaft 0610 to leave the lowest point of slag topping G1.

[0072] The slag scraping rod 061 on the powder cartridge 065 is movably connected to the slag scraping guide inclined plane 0944, so as to drive the slag scraping rod 061 to rotate on the powder cartridge 065 through the slag scraping guide inclined plane 0944, thereby scraping off the ejected coffee slag. The powder cartridge bushing 064 on the right side of the powder cartridge 065 passes through the guide groove on the powder cartridge guide rail 021 and extends into the second powder cartridge track 0941, so that the powder cartridge 065 can move up and down and swing along the second powder cartridge track 0941. The slag ejecting rod guide rail axis 0610 on the right side of the slag ejecting rod 0611 is movably connected to the second slag ejecting rod guide rail axis track 0942, so that the slag ejecting rod 0611 can move up and down along the second slag ejecting rod guide rail axis track 0942 to eject slag. The guide slider 023 on the right side of the powder cartridge guide rail support 022 is movably connected to the second powder cartridge guide rail support assembly track 0943 to guide and limit the lifting movement of the powder cartridge guide rail support 022.

[0073] As Figure 6 shown, the respective points where the second powder cartridge track 0941 bends from top to bottom are the powder pressing top end A2, the swinging starting point B2 of the powder cartridge 065, the outermost swinging point C2 of the powder cartridge 065, the slag scraping starting point D2 of the slag scraping rod 061, and the slag scraping ending point E2 of the slag scraping rod 061. The respective points of the second slag ejecting guide rail axis track 0942 from top to bottom are the highest slag ejecting point F2 and the lowest slag ejecting point G2 of the slag ejecting rod guide rail axis 0610. The respective points of the second powder cartridge guide rail support assembly track 0943 from top to bottom are the highest support point H2 and the lowest support point I2 of the powder cartridge guide rail support 022.
