[0002] In the process of preparing beverages, existing beverage preparation devices usually require a variety of raw materials to be stirred, but the stirring device often has the problem of leakage.

[0003] Although sealing is usually used to solve the leakage problem, the seal may fail after a period of use. If it is not replaced in time, there is still a possibility of leakage and damage to the power source of the stirring device. Utility Model Content

[0004] The purpose of the utility model is to provide a stirring device and a beverage preparation device combined with the stirring device, so as to solve or at least partially alleviate the above problems.

[0005] The utility model provides a stirring device, which comprises: a stirring cup, comprising a stirrer arranged therein, the stirrer is fixed to the bottom of the cup, and the stirring device rotation shaft extends through the bottom of the cup; a motor is arranged below the stirring cup, comprising an output shaft, and the stirring device rotation shaft is driven via the output shaft; wherein the axis of the motor output shaft is offset from the axis of the stirring device rotation shaft, and the motor output shaft is operatively connected to the stirring device rotation shaft via a torque transmission device.

[0006] In the technical solution provided by the utility model, the axis of the motor output shaft of the stirring device is offset from the axis of the stirring shaft, and the torque is transmitted from the motor output shaft to the stirring shaft through the torque transmission device to realize the stirring function. Therefore, under the premise of ensuring the stirring function of the stirring device, when there is leakage along the stirring shaft, it will not flow directly to the motor output shaft, that is, it will not flow into the motor, thereby reducing the possibility of leakage damaging the motor.

[0007] Preferably, the torque transmission device is a gear transmission device, including gears meshing with each other and connected to the motor output shaft and the agitator rotating shaft respectively. The gear transmission device transmits power from the motor output shaft to the agitator rotating shaft, which has a simple structure, high transmission efficiency, and good stability.

[0008] Preferably, a sealing member is provided between the portion of the motor shaft extending out of the motor body and the motor body, so as to further enhance the sealing performance and protect the motor from damage caused by liquid leakage.

[0009] Preferably, a seal is provided between the rotating shaft of the agitator and the torque transmission device to further prevent liquid leakage.

[0010] The utility model also provides a beverage preparation device, which is combined with the stirring device.

[0011] Preferably, an operating table is included, and when the blending cup is placed in place on the operating table, the blender rotating shaft extends through the shaft hole in the operating table and is operatively connected to an intermediate shaft arranged below the operating table, and the intermediate shaft is operatively connected to the motor output shaft through a torque transmission device.

[0012] Preferably, the machine further comprises a mounting platform, the motor is mounted below the mounting platform, and the torque transmission device is arranged between the operating platform and the mounting platform. By setting the mounting platform, the motor is further isolated to protect the motor from damage caused by liquid leakage.

[0013] Preferably, the motor output shaft extends through the mounting platform, and a seal is provided therebetween to further protect the motor.

[0014] Preferably, a drainage groove is provided on the mounting platform around the motor output shaft to drain the leaked liquid from the mounting platform. When the leaked liquid drips onto the mounting platform, the drainage groove can drain the leaked liquid away, reducing the risk of the leaked liquid entering the motor.

[0015] Preferably, when the stirring cup is placed in place on the operating table, its cup mouth corresponds to the discharge port of the beverage preparation device to achieve online stirring.

[0016] By combining the stirring device with the stirring rotating shaft offset from the motor output shaft to the beverage preparation device, if there is leakage from the mounting platform, it will not directly contact the motor output shaft, thereby reducing the risk of the leakage directly entering the motor. In addition, by further providing the sealing member and the drainage groove, multiple protections are provided for the motor to be protected from damage by leakage. This can increase the service life of the motor and reduce the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The stirring device of the utility model comprises: a stirring cup, which comprises a stirrer arranged therein, the stirrer is fixed to the bottom of the cup, and the stirring shaft extends through the bottom of the cup; a motor is arranged below the stirring cup, comprises an output shaft, and drives the stirring shaft via the output shaft; wherein the axis of the motor output shaft is offset from the axis of the stirring shaft, and the motor output shaft is operatively connected to the stirring shaft via a torque transmission device. When the motor is started, the output shaft transmits the torque to the stirring shaft via the torque transmission device, so that the stirrer stirs the substance in the stirring cup.

[0024] By offsetting the axis of the agitator rotating shaft from the axis of the output shaft of its power source (motor), liquid leaking from the agitator rotating shaft (if any) will not flow directly onto the motor output shaft, and will not flow into the motor along the motor output shaft and cause damage to the motor.

[0025] In a preferred embodiment, the torque transmission device can be a gear transmission device, including gears meshing with each other and connected to the motor output shaft and the agitator rotating shaft respectively. The power is transmitted from the motor output shaft to the agitator rotating shaft through the gear transmission device, and the agitator rotating shaft is separated from the motor output shaft by at least a distance of the inner diameter of the gear. Such a setting has a simple structure, high transmission efficiency, and good stability of power transmission.

[0026] In a preferred embodiment, a seal may be provided between the portion of the motor output shaft extending out of the motor body and the motor body, thereby further preventing liquid leaking from the agitator rotating shaft from entering the motor and causing damage to the motor.

[0027] In a preferred embodiment, a seal may be provided between the agitator rotating shaft and the torque transmission device to prevent liquid from leaking.

[0028] The utility model is further described below in conjunction with the accompanying drawings.

When the stirring cup is placed in place on the operating table 6, the stirring device rotating shaft in the stirring cup extends through the shaft hole on the operating table 6 and is operably connected to the coaxially arranged intermediate shaft 2 arranged below the operating table 6. The intermediate shaft 2 below the operating table 6 is indirectly connected to the motor output shaft 4 through the torque transmission device 3. When the motor 5 is turned on, the motor output shaft 4 rotates and transmits the torque to the intermediate shaft 2 through the torque transmission device 3, and also transmits it to the stirring device rotating shaft operatively connected to the intermediate shaft, so that the stirring device enters the operating state. Through the above arrangement, while ensuring the stirring function of the mixer, by offsetting the axis of the motor output shaft and the axis of the stirring device rotating shaft, the motor 5 can be effectively prevented from being damaged by leakage.

The intermediate shaft 2, that is, the blender rotating shaft, is parallel to the motor output shaft 4 and is spaced apart from it by a distance, that is, it is offset by a distance. A torque transmission device 3 can be provided between the intermediate shaft 2 and the motor output shaft 4, which is preferably a gear transmission device. The gear transmission device includes gears that are meshed with each other and are respectively connected to the motor output shaft 4 and the intermediate shaft 2. Thus, power can be transmitted from the motor output shaft to the blender rotating shaft through the gear transmission device.

Figure 3As shown, the torque transmission device 3 is arranged between the operating platform 6 and the mounting platform 7, the motor 5 is installed below the mounting platform 7, and the motor output shaft 4 rotatably extends through the mounting platform 7. The arrangement of the mounting platform 7 can further prevent leakage from flowing into and damaging the motor, and can also provide support for the intermediate shaft 2 and the torque transmission device, the motor output shaft 4 and the motor 5.

[0032] In a preferred embodiment, a seal (not shown) may be provided between the portion of the motor shaft output shaft 4 extending out of the motor body and the motor body. Further, a seal 9 may be provided between the motor output shaft 4 and the mounting platform 7 to further protect the motor 5 from damage due to liquid leakage.

[0033] In a preferred embodiment, a seal 8 may be provided between the agitator rotating shaft and the torque transmission device 3. In addition, an axial hole for the agitator rotating shaft to pass through is provided on the operating table 6, and a seal is provided at the axial hole in a conventional manner. In the present utility model, the provision of the seal 8 between the agitator rotating shaft and the torque transmission device 3 can prevent the liquid used to clean the operating table 6 from leaking under the operating table.

[0034] In a preferred embodiment, when the stirring cup (not shown) is placed in place on the operating table 6, its cup mouth corresponds to the discharge port (not shown) of the beverage preparation device to achieve online stirring while or after discharging.
