The matching component 204 is arranged at a position of the stirrer 202 close to the cup bottom 201, and the matching component 204 and the magnetic component 107 in the driving device 12 generate an interaction force, so that the driving device 12 can drive the stirring device 21 to rotate, and the liquid in the first cup body 2 is stirred.

The brewing process of the exemplary beverage brewing machine of this embodiment is as follows:

firstly, a first cup body 205 is placed in a cup seat 121 of a machine base 1, then a second cup body 301 containing beverage is placed in the first cup body 205, a cover 4 is covered, a heating mechanism 13 is started to heat, when the heating temperature of the beverage brewing machine is lower than a set temperature, a driving device 12 drives a stirring device 21 to rotate anticlockwise through magnetic force, as shown in an arrow direction in (a) of fig. 6, a shifting plate 303 is acted by a biasing device 307 on one hand, and simultaneously is acted by impulsive force formed by the flowing of the liquid in a first cup body 2, so that a hole plug 310 is pressed at the position of a communication hole 309, the liquid in the second cup body 301 is prevented from flowing into the first cup body 205, and the communication hole 309 is closed. When the temperature of the beverage in the first cup body 205 is heated to the set temperature by the heating mechanism 13, the temperature control device 11 feeds back to the controller 105, so as to adjust the rotation direction of the driving device 12, the driving device 12 drives the stirring device 21 to rotate clockwise, as shown by the arrow in fig. 6 (b), since the impulse force of the liquid flow in the first cup body 2 received by the pulling plate 303 is greater than the force of the biasing device 307, the pulling plate 303 rotates around the first stud 302, so that the hole plug 310 is far away from the communication hole 309, so that the communication hole 309 is in an open state, at this time, the liquid in the second cup body 3 flows into the first cup body 2, and different beverages are mixed more fully through the stirring of the stirring device 21.

In other embodiments of the present invention, the user can also manually adjust the controller 105 to control the driving device 12 to drive the rotation direction of the stirring device 21 according to actual conditions, and can also control the valve structure 31 to flexibly adjust the taste of the brewed beverage.
