[0026] This utility model relates to a stirring structure, which is configured as two separable upper and lower parts. One part is fixed to the body of the beverage mixing machine, and the other part is fixed to the liquid storage cup. The two parts are connected to each other and rotated by lifting and lowering to complete the stirring work. After stirring, the two parts are separated, so that the liquid storage cup can be removed from the machine body for user convenience and improved user experience.

[0027] See Figures 1 to 6The stirring structure 100 includes a lower stirring structure 10 and an upper stirring structure 20. The lower stirring structure 10 is fixed to the lid of the liquid storage cup and can be rotated in a controlled manner to stir the liquid in the liquid storage cup. The upper stirring structure 20 is fixed to the body of the beverage preparation machine and can be lowered in a controlled manner to connect with the lower stirring structure 10 and drive the lower stirring structure 10 to rotate, or can be raised in a controlled manner to separate from the lower stirring structure 10, so as to facilitate the removal of the liquid storage cup from the machine body.

[0028] The lower stirring structure 10 includes a rotating shaft 12 fixed to the cup lid and a stirrer 11 located below the cup lid and connected to the end of the rotating shaft 12. It should be understood that the stirrer 11 can rotate relative to the cup lid.

[0029] The upper stirring structure 20 includes a stirring motor 21 and a transmission rod 22. The output shaft of the stirring motor 21 is inserted into the transmission rod 22 and can drive the transmission rod 22 to rotate. The transmission rod 22 can be connected to or separated from the rotating shaft 12 in a controlled lifting and lowering manner.

[0030] In one embodiment, the upper stirring structure 20 further includes an electric push rod assembly, and the transmission rod 22 is driven by the electric push rod assembly to rise or fall.

[0031] In one embodiment, the transmission rod 22 is provided with an assembly cavity and a sliding groove. The assembly cavity extends along one end of the transmission rod 22 to the other end, and the sliding groove extends axially around the transmission rod 22 and communicates with the assembly cavity.

[0032] The electric push rod assembly includes an electric push rod 27, a pressure plate 25, a compression spring 23, and a limiting pin 24. The pressure plate 25 is fixed to the end of the electric push rod and covers the output shaft of the motor. The limiting pin 24 is fixed to the output shaft and passes through the slide groove. The compression spring 23 is sleeved on the outer periphery of the output shaft and springs between the pressure plate 25 and the limiting pin 24, providing transmission, buffering, and reset functions.

[0033] In one embodiment, the electric push rod assembly further includes a pad 26 disposed between the stirring motor 21 and the pressure plate 25, and the output shaft passes through the pad 26.

[0034] In one embodiment, the end of the transmission rod 22 away from the assembly cavity is provided with a connector 221, and the end of the rotating shaft 12 away from the stirrer 11 is provided with a slot, and the connector is pluggably connected to the slot. In this embodiment, the connector is straight-lined, and the slot is cross-shaped. Furthermore, the rotating shaft 12 is mounted on the cup lid via bearings, thereby ensuring smooth rotation of the rotating shaft 12.

[0035] In one embodiment, the pressure plate 25 is generally Z-shaped, including a first horizontal plate, a second horizontal plate, and a vertical plate connecting the two horizontal plates. The first horizontal plate is fixed to the end of the electric push rod, and the second horizontal plate is sleeved on the output shaft of the stirring motor 21 and located above the first horizontal plate. This allows the stirring motor 21 to be positioned on one side of the electric push rod, avoiding the upper stirring structure 20 occupying a large installation space in terms of height, which is beneficial for the miniaturization of the beverage preparation machine.

[0036] In one embodiment, the lower stirring structure 10 further includes a guide sleeve 13 located directly above the rotating shaft 1212. The end of the transmission rod 22 away from the stirring motor 21 is inserted into the guide sleeve, thereby restricting the lower end of the transmission rod 22 within the guide sleeve 13, i.e., limiting it to be coaxial with the rotating shaft 1212, thus ensuring that the transmission rod 22 and the rotating shaft 12 can be accurately connected, ensuring the normal use of the beverage preparation machine.

[0037] As a second aspect, the present invention also provides a beverage preparation machine, including a body 200, a liquid storage cup 300 detachably hung on the body, a cup lid 301 disposed on the opening of the liquid storage cup, and the aforementioned stirring structure 100, wherein the upper stirring structure 20 is disposed on the body 200, the rotating shaft of the lower stirring structure 10 is rotatably mounted on the cup lid 301, and the stirrer 11 is located inside the liquid storage cup 300.

[0038] The working principle of this beverage mixing machine is as follows:

[0039] When stirring is required, the control system on the machine body outputs a control command to the electric push rod assembly, causing it to move the pressure plate downwards. The pressure plate acts on the compression spring, which transmits the force to the limit pin, causing the limit pin to slide downwards (the stirring motor moves downwards synchronously) and press against the lower end of the slide groove. The force is then transmitted to the transmission rod, which moves downwards to connect with the rotating shaft. Once the connection is complete, the control system outputs a control signal to stop the push rod in the electric push rod from extending further and controls the stirring motor to start rotating, driving the stirrer to stir the liquid in the storage cup.

[0040] Once mixing is complete, the control system outputs a control command to stop the motor's rotation, controls the electric push rod to work, causing the pressure plate of the electric push rod to rise. Under the elastic force of the compression spring, the mixing motor gradually returns to its original position, and the transmission rod rises and separates from the rotating shaft, thus allowing the liquid storage cup to be removed from the machine body.

[0041] In summary, the stirring structure of this utility model is divided into two parts: an upper stirring structure 20 and a lower stirring structure 10. The upper stirring structure 20 is fixed to the machine body 200, and the lower stirring structure 10 is fixed to the cup lid 301. The upper stirring structure 20 is connected to or separated from the rotating shaft of the lower stirring structure 10 by the transmission rod of the upper stirring structure 20. Thus, the two stirring structures can be connected to complete the stirring function when stirring is required. After stirring is completed, the two stirring structures can be separated, so that the liquid storage cup and its lid of the beverage mixing machine can be removed from the machine body, which is convenient for users.

[0042] In this embodiment, the stirrer is a plate stirrer. In other embodiments, the stirrer may also be a rod stirrer.
