[0048] The top of the container 2 is provided with a flange that supports the edge of the top opening of the container 1.

[0049] The valve assembly 7 includes a connecting plate 701 and a valve body 702, with the valve body 702 fixed to the connecting plate 701; The inner cup 6 is provided with a connecting post 602, which is rotatably connected to the connecting plate 701. The connecting post 602 is provided with a spring 17, and the two ends of the spring 17 abut against the inner cup 6 and the connecting plate 701 respectively, so that the valve assembly 7 is elastically rotatably connected to the inner cup 6, and the valve body 702 seals the through hole 601 in the initial state through the elastic force of the spring 17.

[0050] A protruding post is located at the center of the bottom of the inner cup 6, and an inner cavity is provided inside the protruding post.

The material can be tea leaves, milk, coffee powder, etc. Brewing parameters are set via the touchscreen display, buttons, or knobs on the control panel 15 on the base 1. The temperature detector 11 on the heating element 3 monitors the temperature of the container 2 in real time and transmits the temperature signal to the control board 16. When the liquid temperature reaches the set temperature, the control board 16 activates the driver 5 in the bottom cavity 2101 on the outer side of the control bracket 21. A magnetic element 8 is fixed in the mounting base 10 at the output end of the driver 5, and a magnetic mating element 9 is fixed in the stirring seat 401 of the stirring assembly 4.

The stirring base 401 of the stirring assembly 4 is rotatably connected to the connecting shaft 201 inside the container 2. The rotation of the stirring base 401 drives the spring ring 402, which is fixed to the outside by the connecting ring 403, to stir the liquid. The force generated by the liquid flow acts on the valve assembly 7. The liquid force overcomes the elastic force of the spring 17, causing the connecting plate 701 to drive the valve body 702 fixed on it to leave the through hole 601 of the inner cup 6. The material in the inner cup 6 enters the container 2 through the through hole 601 and mixes with the liquid to achieve brewing. The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
