The above barrel body, lock hook, screw, sleeve body or push head are correspondingly provided with micro switches, and real-time monitoring is performed when the barrel body, lock hook, screw, sleeve body or push head reaches the powder pressing or corresponding position.

[0027] The gear motor 901 of the motor gear assembly is vertically arranged on one side of the outer diameter of the casing, and the motor shaft of the gear motor is meshed and connected with the screw through the inner thread of the center hole of the output gear of the gear assembly, or is meshed and connected with the screw through the outer thread of the output gear of the gear assembly. A barrel cover assembly 2 is provided above one side of the powder receiving port on the top of the housing of the brewing seat assembly, and the cover hole of the barrel cover assembly is aligned with the powder receiving port. A powder scraper plate 201 with a U-shaped opening is provided in the barrel cover assembly, and a powder scraper shaft 202 is provided at the open end of the powder scraper plate. A downwardly inclined convex slag pouring plate 105 is provided on the outer diameter of the opening side of the slag pouring channel of the housing of the brewing seat assembly; a loading and unloading button is provided on the outer diameter side of the housing of the brewing seat assembly, and the brewing seat assembly is fixed in the groove of the opening on one side of the body through the loading and unloading button.

[0028] like Figure 7 As shown, the outer diameter of the sleeve body is provided with a head cover assembly 10, a screw sleeve 1002 is provided in the shell 1001 of the head cover assembly, the screw sleeve is connected to the sleeve body as a whole, the outer thread of the thread outer diameter is provided with a gear 1003, the gear ring of the outer diameter of the gear extends out of the shell, and the gear ring on one side of the gear is meshed with the transmission gear of the transmission motor. The head cover assembly is connected to the brewing seat assembly as a whole, or the head cover assembly and the brewing head assembly are integrally arranged in a groove opened on one side of the body.

[0029] The specific operations of the powder receiving state, powder pressing brewing state and slag discharge state of the mechanism are as follows: in the powder receiving state, the rotary barrel motor drives the barrel body of the brewing seat assembly back to the origin after being powered on, and the barrel mouth of the barrel body is vertically aligned with the powder receiving port of the shell; at the same time, the push rod motor or the rotary barrel motor drives the slag discharge push rod of the brewing seat assembly back to the origin after being powered on, so that an open-type cavity is generated in the barrel body, waiting for powder receiving, and the powder receiving action is completed at this time. In the powder pressing brewing state, the rotary barrel motor drives the barrel body of the brewing seat assembly to the side of the brewing head assembly under power on, and the barrel mouth of the barrel body is vertically aligned with the brewing port of the shell, and the gear motor drives the screw rod to move downward to drive the sleeve body to move the lock hook toward the brewing seat assembly until the lock hook and the buckle rib of the barrel body are locked and sealed, and the end face of the sleeve body is sealed against the barrel mouth of the barrel body of the brewing seat assembly, and the push head is pressed into the barrel body, and the slag discharge push rod of the brewing seat assembly moves upward, and the coffee powder in the barrel body is made into a powder cake; then, wait for the hot water from the boiler of the coffee machine to extract and brew coffee. In the slag discharge state, the rotary barrel motor drives the barrel body of the brewing seat assembly, and the gear motor drives the screw, push head, and sleeve body to reset. At the same time, the locking hook and the clamping rib at the barrel body of the brewing seat assembly fall off. After power is turned on, the push rod motor drives the slag discharge push rod of the brewing seat assembly to push the coffee slag cake out of the barrel body. The coffee slag cake falls out of the shell through the slag pouring plate, completing the slag discharge action. The above structure or the push rod motor is omitted, and the slag discharge push rod of the brewing seat assembly is driven by the rotary barrel motor to move up and down, and realize powder pressing and slag discharge.

[0030] like Figure 8 As shown, the barrel body of the brewing seat assembly is symmetrically provided with raised limit posts 1023 on both sides below the buckle ribs; when the lock hook is buckled and sealed with the buckle ribs of the barrel body, the barrel body is extended through the barrel seat (rotation continues), and the limit posts of the barrel body are abutted and limited to the brewing port at the top of the shell. In the powder receiving state, after the motor is powered on, the brewing cavity of the barrel body rotates through the gears and the barrel seat, and returns to the powder pressing state to wait for powder receiving, and the powder receiving action is completed at this time. In the powder pressing brewing state, after the motor is powered on, it rotates through the gears and the barrel seat to turn the brewing cavity of the barrel body to the upper piston (push head) position, and then the motor at the upper piston drives the screw and the push head to push the upper piston downward, and the push rod at the barrel seat drives the lower piston (slag discharge push rod) in the barrel body to move upward, and the coffee powder in the brewing cavity in the barrel body is brewed into a powder cake. Finally, wait for the hot water from the boiler to extract and brew coffee, and the powder pressing brewing action is completed at this time.

[0031] In summary, the brewer in the traditional coffee machine can only use 14g of coffee powder at most due to structural reasons, and the brewing chamber diameter is within 46mm, and it cannot withstand 10bar water pressure, resulting in low coffee quality; this mechanism uses 18-22g of coffee powder, a brewing chamber larger than 52mm, and a brewing pressure of 9-13bar to brew standard Italian coffee, which effectively solves the above problems. The large-capacity powder chamber in the barrel of this mechanism is not easily damaged under the pressure of the screw and the push head, and the use of a locking hook structure allows it to better withstand pressure during work.
