Description

Technical Field

[0001] This utility model relates to the field of small household appliances, and in particular to a mixing cup assembly for a food processor. Background Technology

[0002] Food processors, such as soy milk makers, meat grinders, and high-speed blenders, typically consist of a base and a detachable blending cup attached to the base. The base houses the drive motor, and the blending cup has blades mounted on its bottom. When the blending cup is attached to the base, the drive motor's shaft is connected to the blades. Because the drive motor is located in the base and the blending cup and base are separate components, these food processors are relatively bulky and inconvenient to carry. Furthermore, the repeated assembly and disassembly of the blending cup and base during daily use easily leads to deformation and loosening of the connecting structure, increasing the risk of equipment damage. Utility Model Content

[0003] In view of this, the present invention provides a mixing cup assembly for a food processor to solve the problem of how to reduce the overall size of the food processor and avoid the repeated assembly and disassembly of the mixing cup during use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A mixing cup assembly for a food processor includes a mixing cup body, a drive motor, and mixing blades; the mixing cup body includes an upper cup body, a lower cup body, and a partition integrally formed and connected, the upper cup body has a food receiving cavity with an open top, the lower cup body has a motor receiving cavity with an open bottom, and the food receiving cavity and the motor receiving cavity are isolated from each other by the partition. The drive motor is assembled in the motor housing cavity. The drive motor includes a stator, a rotor, a rotating shaft, and a rear housing. The lower cup body and the partition plate, which are connected to each other, form the front housing of the drive motor. The rear housing is connected to the bottom end of the lower cup body and clamps and fixes the stator to the lower cup body. The rotor passes through the stator and rotates with the stator. The rotating shaft passes through the rotor. The first end of the rotating shaft passes through the partition and extends into the food receiving cavity. The stirring blade is connected to the first end of the rotating shaft in the food receiving cavity.

[0005] In the specific design, the partition has a protrusion extending toward the food receiving cavity at its center. The protrusion has three coaxial mounting holes—a first mounting hole, a second mounting hole, and a first shaft hole—arranged sequentially from bottom to top with decreasing diameters. A gasket and a first bearing are installed in the first mounting hole, and a sealing ring is installed in the second mounting hole. The first end of the rotating shaft passes sequentially through the first bearing, the gasket, the sealing ring, and the first shaft hole into the food receiving cavity. The rear housing has a third mounting hole at its center, in which a second shaft hole is formed. A second bearing is installed in the third mounting hole, and the second end of the rotating shaft passes through the second bearing and exits through the second shaft hole.

[0006] In a specific embodiment, within the motor housing cavity, there is a gap between the end face of the drive motor facing the partition and the partition, and the height of the gap is 1cm to 1.5cm.

[0007] In the specific design, multiple ventilation openings communicating with the gap are provided on the side wall of the lower cup body.

[0008] In the specific design, there are four ventilation openings, with every two ventilation openings arranged opposite each other on the side wall of the lower cup body.

[0009] In the specific design, the rear shell is made of plastic.

[0010] The food processor mixing cup assembly provided in this embodiment includes an integrally formed upper cup body, a lower cup body, and a partition. The upper cup body has a top-opening food receiving cavity, and the lower cup body has a bottom-opening motor receiving cavity. A drive motor is mounted in the motor receiving cavity, and the interconnected lower cup body and partition form the front housing of the drive motor. In other words, the mixing cup body and the drive motor are integrated into a single structure. Compared to traditional food processors where the mixing cup and the drive structure (motor mounted in the base) are separate components, the mixing cup assembly of this application reduces the overall size of the food processor, making it more portable. Furthermore, it eliminates the need for repeated assembly and disassembly of the mixing cup and the drive structure containing the motor during daily use, reducing the risk of damage to the food processor and extending its lifespan. Furthermore, in traditional food processors, the front housing of the drive motor is usually made of aluminum alloy. In the present application, a part of the structure of the mixing cup (lower cup and partition) is used as part of the structure of the drive motor (front housing). The drive motor does not need to be set up with a separate front housing, thereby reducing the overall weight of the food processor. Attached Figure Description

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0014] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0015] This utility model provides a mixing cup assembly for a food processor. (See also...) Figures 1 to 4 The stirring cup assembly mainly includes a stirring cup body 1, a drive motor 2, and stirring blades (not shown in the attached drawings).

[0016] The mixing cup 1 includes an upper cup 11, a lower cup 12, and a partition 13 integrally formed and connected. The upper cup 11 has a food receiving cavity 14 with an open top, and the lower cup 12 has a motor receiving cavity 15 with an open bottom. The food receiving cavity 14 and the motor receiving cavity 15 are isolated from each other by the partition 13.

[0017] The drive motor 2 is assembled in the motor housing cavity 15. The drive motor 2 includes a stator 21, a rotor 22, a rotating shaft 23 and a rear housing 24. The lower cup body 12 and the partition 13, which are connected to each other, form the front housing of the drive motor 2.

[0018] Specifically, the rear housing 24 is connected to the bottom end of the lower cup body 12 and clamps and fixes the stator 21 with the lower cup body 12. The rotor 22 passes through the stator 21 and rotates with the stator 21. The rotating shaft 23 passes through the rotor 22. The first end of the rotating shaft 23 passes through the partition 13 and extends into the food receiving cavity 14. The stirring blade is connected to the first end of the rotating shaft 23 in the food receiving cavity 14.

[0019] It should be noted that for a food processor that includes the mixing cup assembly as described above, a support base can be provided to fix the bottom of the mixing cup assembly to the support base. The support base is provided with a circuit board and operation buttons for controlling the drive motor 2.

[0020] As described above, the food processor's mixing cup assembly integrates the mixing cup body 1 and the drive motor 2 into a single unit. This reduces the overall size of the food processor, making it more portable. Furthermore, it eliminates the need for repeated assembly and disassembly of the mixing cup and the drive structure containing the motor during daily use, reducing the risk of damage and extending the lifespan of the device. Moreover, by utilizing a portion of the structure of the mixing cup body 1 (lower cup body 12 and partition 13) as part of the drive motor 2 structure (front housing), the weight of the drive motor 2 can be reduced, thereby reducing the overall weight of the food processor.

[0021] In this embodiment, the partition 13 has a protrusion 131 extending toward the food receiving cavity 14 at its center. The protrusion 131 has coaxially arranged first mounting holes 132, second mounting holes 133, and a first shaft hole 134, arranged sequentially from bottom to top with decreasing diameters. A gasket 3 and a first bearing 4 are installed in the first mounting hole 132, and a sealing ring 5 is installed in the second mounting hole 133. The first end of the rotating shaft 23 passes sequentially through the first bearing 4, the gasket 3, the sealing ring 5, and the first shaft hole 134 into the food receiving cavity 14. The rear housing 24 has a third mounting hole 241 at its center. A second shaft hole 242 is formed in the third mounting hole 241, and a second bearing 6 is installed in the third mounting hole 241. The second end of the rotating shaft 23 passes through the second bearing 6 and exits through the second shaft hole 242.

[0022] In this embodiment, within the motor housing cavity 15, a gap 16 is formed between the end face of the drive motor 2 facing the partition 13 and the partition 13. The height of the gap 16 is preferably set to 1cm to 1.5cm. Furthermore, a plurality of ventilation openings 17 communicating with the gap 16 are provided on the side wall of the lower cup body 12. For a food processor, when the drive motor 2 drives the stirring blades to rotate and stir, cut, or crush food, the drive motor 2 generates a large amount of heat. By providing the gap 16 and the plurality of ventilation openings 17 communicating with the gap 16, a good heat dissipation channel is formed within the motor housing cavity 15, improving the heat dissipation performance of the drive motor 2.

[0023] In a preferred embodiment, the number of vents 17 is four, with every two vents 17 arranged opposite each other on the side wall of the lower cup body 12.

[0024] In a preferred embodiment, the rear housing 24 is made of plastic material, such as PET. In conventional solutions, the rear housing of the drive motor is typically made of metal (most commonly aluminum alloy). In this application, the rear housing 24 is changed from a traditional metal material to a plastic material, which reduces noise transmission, isolates the noise during motor rotation, and significantly reduces the amount of noise transmitted to the external environment.

[0025] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
