At this time, the first rocker assembly 2 triggers the first contact switch 81, and the first drive module 1 stops working. The powder dropping module 5 can be started, and the powder filling function is realized. After the powder dropping is completed, the funnel 10 returns to the initial position under the action of the first drive module 1. At this time, the first rocker assembly 2 triggers the second contact switch 82, and the first drive module 1 stops working. The rear end of the sliding baffle 6 blocks the powder outlet 51, preventing the powder dropping module 5 from dropping powder and preventing the steam in the funnel 10 from entering the powder dropping channel 52 to cause powder blocking.

[0056] The first rocker assembly 2 triggers the second contact switch 82, and the first drive module 1 stops working. The funnel 10 is below the powder pressing head 14 installed on the main support 11. At this time, the second drive module 12 starts to work. The second drive shaft 121 of the second drive module 12 drives the second rocker assembly 13, and the second output shaft 135 of the second rocker assembly 13 drives the powder pressing head 14 to move downward along the powder pressing channel 161 arranged inside the shell 16, so as to press the powder in the funnel 10. When the second rocker assembly 13 triggers the fourth contact switch 115, the second drive module 12 stops working. The water source enters the funnel 10 through the powder pressing head 14 to realize extraction of beverage. After the extraction is completed, the second drive module 12 works, and the powder pressing head 14 moves upward along the powder pressing channel 161 under the action of the second rocker assembly 13. When the second rocker assembly 13 triggers the third contact switch 114, the second drive module 12 stops working. The whole process is rapid and silent, the structure is simple, and the efficiency is high.

[0057] The brewing structure of the present application realizes the automatic powder pressing process through the principle of curved arm rocker, converts the rotary motion into linear motion, realizes the force amplification and realizes the longer stroke through the reasonable and ingenious design of the crank radius and the length of the force arm of the first rocker assembly 2 and the second rocker assembly 13, respectively limits the specific motion trajectory of the sliding baffle 6 and the powder head 14, is simpler, more economical and more suitable for specific space requirements than the automatic powder pressing brewing structure in the related art using linear guide rails. And the powder filling direction of the present application can be variable, which is different from the direction of the powder pressing extraction; the powder pressing channel 161 and the powder pressing channel 161 do not coincide. The mechanical or electronic switch placed on both sides of the first rocker assembly 2 and the second rocker assembly 13 realizes the start-stop function of the driving module in the module.

[0058] In summary, the brewing structure of the present application avoids the situation that the powder pressing channel 161 and the powder pressing channel 161 coincide, avoids the phenomenon that the residual powder in the powder pressing channel 52 falls on the powder pressing head 14, avoids the defect that the powder pressing head 14 has insufficient running stroke after a long time, solves the problem that the powder pressing head cannot normally function due to the coincidence of the powder pressing channel 52 and the powder pressing channel 161. The brewing structure of the present application also avoids the situation that the powder pressing channel 52 and the powder pressing channel 161 are communicated, which can easily cause the water vapor in the extraction solution to run into the powder pressing channel 161, causing the powder to be blocked. The present application can realize the closure of the powder pressing channel 52 during the movement of the funnel 10, prevent the powder pressing channel 52 from being damp and falling, solve the problem that the powder pressing channel 52 is blocked due to the communication between the powder pressing channel 52 and the powder pressing channel 161, and the machine cannot run. The present application provides a three-in-one brewing structure for realizing automatic powder filling and pressing by moving the funnel 10 between the powder filling position and the powder pressing position through the first rocker assembly 2, and the sliding baffle 6 can cover the powder filling port 51, thereby avoiding the coincidence of the powder pressing and powder filling channels. And the brewing structure of the present application makes the movement of the sliding baffle 6, the funnel 10 and the powder head 14 at the output end relatively stable, has high reliability and stability.

[0059] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
