Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a blending cup assembly and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Existing food processors are large and tall, taking up a lot of space and prone to vibration during use. Utility Model Content

[0003] This application provides a blending cup assembly and a food processor, which has a smaller overall height, occupies less space, and generates less vibration during use.

[0004] This application provides a mixing cup assembly. The mixing cup assembly includes a mixing cup and a heating plate, a blade assembly, and a motor assembly disposed at the bottom of the mixing cup. The motor assembly includes a bracket, a brushless motor, a high-voltage upper coupler, and a low-voltage upper coupler. The brushless motor, the high-voltage upper coupler, and the low-voltage upper coupler are respectively fixed to the bracket, and the high-voltage upper coupler and the low-voltage upper coupler are arranged around the brushless motor. The high-voltage upper coupler and the low-voltage upper coupler at least partially overlap with the brushless motor in the height direction. The ratio of the length of the high-voltage upper coupler to the length of the low-voltage upper coupler is between 1.1 and 1.5, and the ratio of the width of the high-voltage upper coupler to the width of the low-voltage upper coupler is also between 1.1 and 1.5. By implementing the high-voltage and low-voltage connections in a conventional upper coupler separately through high-voltage and low-voltage upper couplers, respectively, and considering that the sizes of the high-voltage and low-voltage upper couplers are smaller than those of conventional couplers, sufficient space is provided outside the brushless motor to accommodate the high-voltage and low-voltage upper couplers. This allows the high-voltage and low-voltage upper couplers to be positioned around the brushless motor, ensuring that they at least partially overlap with the brushless motor in the height direction. This effectively reduces the height of the blending cup assembly, thereby reducing the overall height of the blender and making it more compact and space-saving. Furthermore, by limiting the size ratio of the high-voltage and low-voltage upper couplers, a foolproof mechanism is implemented.

[0005] Furthermore, the length of the high-voltage upper coupler ranges from 40 mm to 65 mm, and the width ranges from 10 mm to 20 mm; the length of the low-voltage upper coupler ranges from 35 mm to 60 mm, and the width ranges from 9 mm to 15 mm. By limiting the dimensions of the high-voltage and low-voltage upper couplers, sufficient space is ensured on the outside of the brushless motor to accommodate them.

[0006] Furthermore, the height of the high-voltage upper coupler ranges from 10 mm to 30 mm, and the height of the low-voltage upper coupler also ranges from 10 mm to 30 mm. This ensures that both the high-voltage and low-voltage upper couplers have suitable heights, avoiding increasing the overall height of the stirring cup assembly.

[0007] Furthermore, the brushless motor includes several mounting portions, and the brushless motor is mounted to the bracket through the mounting portions. A receiving space is formed between two adjacent mounting portions, and the high-voltage and low-voltage couplers are located in different receiving spaces. In this way, the receiving space between the mounting portions can be fully utilized to accommodate the high-voltage and low-voltage couplers, making the stirring cup assembly structure more compact and lower in height.

[0008] Furthermore, the brushless motor includes four mounting portions, forming four receiving spaces. The high-voltage upper coupler and the low-voltage upper coupler are respectively disposed in two opposite receiving spaces. Similarly, the high-voltage lower coupler and the low-voltage lower coupler on the base are also disposed opposite each other. This arrangement is more aesthetically pleasing, and when the stirring cup assembly is installed onto or removed from the base, the upper and lower couplers are less likely to jam, resulting in smoother operation.

[0009] Furthermore, the high-voltage top coupler includes a plurality of first conductive terminals arranged in a row along an arc or a straight line; the low-voltage top coupler includes a plurality of second conductive terminals arranged in a row along an arc or a straight line. In this way, the high-voltage and low-voltage top couplers can be better matched to the accommodating space.

[0010] Furthermore, the bottom end of the high-voltage upper coupler is flush with the bottom end of the brushless motor, and the bottom end of the low-voltage upper coupler is also flush with the bottom end of the brushless motor; or, the height difference between the bottom ends of the high-voltage upper coupler and the bottom end of the brushless motor does not exceed 10 mm, and the height difference between the bottom ends of the low-voltage upper coupler and the bottom end of the brushless motor does not exceed 10 mm. This ensures a more compact structure and lower height for the stirring cup assembly.

[0011] Furthermore, the brushless motor includes a front cover, a rotor assembly, and a stator assembly. The front cover includes a receiving cavity, within which both the rotor assembly and the stator assembly are disposed. The rotor assembly includes a motor shaft rotatably connected to the front cover, and the stator assembly is fixed to the front cover. The ends of the rotor assembly and the stator assembly furthest from the front cover are exposed. Because the ends of the rotor assembly and the stator assembly furthest from the front cover are exposed, meaning the brushless motor does not have a rear cover, the height of the brushless motor is reduced, which in turn helps to further reduce the height of the food processor.

[0012] Furthermore, the stirring cup includes a cup body and a cup base, with the cup base integrally formed with the support. This simplifies the structure and makes assembly easier.

[0013] This application also provides a food processor. The food processor includes: a base with a high-voltage lower coupler and a low-voltage lower coupler; and a mixing cup assembly as described above, assembled on the base, wherein the high-voltage upper coupler is connected to the high-voltage lower coupler, and the low-voltage upper coupler is connected to the low-voltage lower coupler.

[0014] Furthermore, the food processor includes a soundproof cover over the mixing cup assembly, the soundproof cover being supported on the base. Attached Figure Description

[0024] Please see Figures 1 to 7 The food processor 100 can be used to make soy milk, rice paste, juice, etc. The food processor 100 includes a base 10, a blending cup assembly 20, and a lid 30.

[0025] The base 10 is equipped with a high-voltage coupler 112 and a low-voltage coupler 113. The base 10 includes a main housing 11 and a bottom cover 12 that mates with the main housing 11. A control circuit board and a power board 13 are also provided inside the base 10. The high-voltage coupler 112 and the low-voltage coupler 113 are respectively fixed to the main housing 11, and both pass through the main housing 11. Specifically, the main housing 11 is provided with studs 114, and fasteners 115 pass through the positioning holes 1121 of the high-voltage coupler 112 and the low-voltage coupler 113 and are locked with the studs 114, thereby fixing the high-voltage coupler 112 and the low-voltage coupler 113 to the main housing 11.

[0026] A stirring cup assembly 20 is assembled on the base 10. The stirring cup assembly 20 includes a stirring cup 21 and a heating plate 22, a blade assembly 23, and a motor assembly 40 disposed at the bottom of the stirring cup 21. The motor assembly 40 includes a bracket 41, a brushless motor 42, a high-voltage upper coupler 481, and a low-voltage upper coupler 482. The brushless motor 42, the high-voltage upper coupler 481, and the low-voltage upper coupler 482 are respectively fixed to the bracket 41, and the high-voltage upper coupler 481 and the low-voltage upper coupler 482 are arranged around the brushless motor 42. The high-voltage upper coupler 481 and the low-voltage upper coupler 482 at least partially overlap with the brushless motor 42 in the height direction. The high-voltage upper coupler 481 is connected to the high-voltage lower coupler 112, and the low-voltage upper coupler 482 is connected to the low-voltage lower coupler 113. The blade assembly 23 is disposed at the top end of the motor shaft 4281 of the brushless motor. A mixing cup 21 is used to hold food ingredients, a heating plate 22 is used to heat the food ingredients in the mixing cup 21, and a blade assembly 23 is used to mix and pulverize the food ingredients in the mixing cup 21. The mixing cup 21 includes a cup body 211, a cup base 212, and a cup handle 216. The cup base 212 has a coupler hole 2121 for the high-voltage coupler 481 and the low-voltage coupler 482 to pass through. A sealing ring 219 is provided between the cup body 211 and the cup base 212. The heating plate 22 is equipped with a temperature controller 29.

[0027] In the illustrated embodiment, the main housing 11 is provided with two guide posts 117 of different sizes, and the cup holder 212 is provided with two guide grooves 2127 that correspond to and match the guide posts 117. The cooperation between the guide posts 117 and the guide grooves 2127 can guide the installation of the stirring cup assembly 20 and also prevent mistakes.

[0028] The ratio of the length of the high-voltage upper coupler 481 to the length of the low-voltage upper coupler 482 is between 1.1 and 1.5, and the ratio of the width of the high-voltage upper coupler 481 to the width of the low-voltage upper coupler 482 is between 1.1 and 1.5.

[0029] In some embodiments, the ratio of the length of the high-voltage top coupler 481 to the length of the low-voltage top coupler 482 can be 1.1, 1.2, 1.3, 1.4, 1.5, or any value between any two adjacent values ​​mentioned above. The ratio of the width of the high-voltage top coupler 481 to the width of the low-voltage top coupler 482 can be 1.1, 1.2, 1.3, 1.4, 1.5, or any value between any two adjacent values ​​mentioned above.

[0030] Because the high-voltage and low-voltage connections in a conventional upper coupler are implemented through high-voltage upper coupler 481 and low-voltage upper coupler 482 respectively, and the dimensions of high-voltage upper coupler 481 and low-voltage upper coupler 482 are smaller than those of conventional couplers, there is sufficient space outside the brushless motor 42 to accommodate high-voltage upper coupler 481 and low-voltage upper coupler 482. This allows the high-voltage upper coupler 481 and low-voltage upper coupler 482 to be positioned around the brushless motor 42, ensuring that they at least partially overlap with the brushless motor 42 in the height direction. This effectively reduces the height of the mixing cup assembly 20, thereby reducing the overall height of the blender 100, making the blender 100 more compact and space-saving. Furthermore, by limiting the size ratio of the high-voltage upper coupler 481 and low-voltage upper coupler 482, a foolproof mechanism can be implemented.

[0031] The length of the high-voltage upper coupler 481 ranges from 40 mm to 65 mm, and the width ranges from 10 mm to 20 mm; the length of the low-voltage upper coupler 482 ranges from 35 mm to 60 mm, and the width ranges from 9 mm to 15 mm. By limiting the dimensions of the high-voltage upper coupler 481 and the low-voltage upper coupler 482, sufficient space is ensured on the outside of the brushless motor 42 to accommodate the high-voltage upper coupler 481 and the low-voltage upper coupler 482.

[0032] In some embodiments, the length of the high-voltage top coupler 481 can be 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, or any value between any two adjacent values. The width of the high-voltage top coupler 481 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, or any value between any two adjacent values. The length of the low-voltage top coupler 482 can be 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, or any value between any two adjacent values. The width of the low-voltage top coupler 482 can be 9 mm, 11 mm, 13 mm, 15 mm, or any value between any two adjacent values.

[0033] Preferably, the height of the high-voltage upper coupler 481 is between 10 mm and 30 mm, and the height of the low-voltage upper coupler 482 is between 10 mm and 30 mm. This ensures that the high-voltage upper coupler 481 and the low-voltage upper coupler 482 have suitable heights, avoiding increasing the overall height of the stirring cup assembly 20.

[0034] The height of the high-voltage coupler 481 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, or any value between any two adjacent values ​​mentioned above. The height of the low-voltage coupler 482 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, or any value between any two adjacent values ​​mentioned above.

[0035] The brushless motor 42 includes several mounting portions 422, which are mounted on the bracket 41. Several accommodating spaces 423 are formed between adjacent mounting portions 422. The high-voltage coupler 481 and the low-voltage coupler 482 are located in different accommodating spaces 423. This design fully utilizes the accommodating spaces 423 between the mounting portions 422 to accommodate the high-voltage coupler 481 and the low-voltage coupler 482, resulting in a more compact structure and lower height for the stirring cup assembly 20.

[0036] In the illustrated embodiment, the bracket 41 is provided with a plurality of mounting posts 419. Fasteners 115 pass through holes in the mounting portion 422 and lock with the mounting posts 419, thereby fixing the brushless motor 42 to the bracket 41. The high-voltage coupler 481 and the low-voltage coupler 482 can be fixed to the bracket 41 by fasteners or other means.

[0037] The brushless motor 42 includes four mounting portions 422, forming four receiving spaces 423. The high-voltage upper coupler 481 and the low-voltage upper coupler 482 are respectively disposed in two opposite receiving spaces 423. The high-voltage lower coupler 112 and the low-voltage lower coupler 113 on the base are also disposed opposite each other. This arrangement is more aesthetically pleasing, and when the stirring cup assembly 20 is installed on or removed from the base 10, the upper and lower couplers are less likely to jam, resulting in smoother operation.

[0038] The high-voltage top coupler 481 includes a plurality of first conductive terminals 4811, which are arranged in a row along an arc or a straight line; the low-voltage top coupler 482 includes a plurality of second conductive terminals 4821, which are also arranged in a row along an arc or a straight line. Thus, the high-voltage top coupler 481 and the low-voltage top coupler 482 can better match the accommodating space 423.

[0039] The bottom end of the high-voltage upper coupler 481 is flush with the bottom end of the brushless motor 42, and the bottom end of the low-voltage upper coupler 482 is also flush with the bottom end of the brushless motor 42; alternatively, the height difference between the bottom ends of the high-voltage upper coupler 481 and the brushless motor 42 does not exceed 10 mm, and the height difference between the bottom ends of the low-voltage upper coupler 482 and the brushless motor 42 does not exceed 10 mm. This ensures a more compact structure and lower height for the stirring cup assembly 20.

[0040] In some embodiments, the height difference between the bottom end of the high-voltage coupler 481 and the bottom end of the brushless motor 42 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or any value between any two adjacent values ​​mentioned above. The height difference between the bottom end of the low-voltage coupler 482 and the bottom end of the brushless motor 42 is also 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or any value between any two adjacent values ​​mentioned above.

[0041] The brushless motor 42 includes a front cover 429, a rotor assembly 428, and a stator assembly 427. The front cover 429 includes a receiving cavity 4291, within which both the rotor assembly 428 and the stator assembly 427 are disposed. The rotor assembly 428 includes a motor shaft 4281 rotatably connected to the front cover 429. The stator assembly 427 is fixed to the front cover 429, with the ends of the rotor assembly 428 and the stator assembly 427 exposed away from the front cover 429. Because the ends of the rotor assembly 428 and the stator assembly 427 are exposed, meaning the brushless motor 42 does not have a rear cover, the height of the brushless motor 42 is reduced, which in turn helps to further reduce the height of the food processor 100.

[0042] In one embodiment, the cup holder 212 and the bracket 41 are integrally formed. This simplifies the structure and makes assembly easier.

[0043] The food processor 100 includes a soundproof cover 50 that covers the mixing cup assembly 20 and is supported on the base 10. Thus, the soundproof cover 50 effectively reduces the noise generated by the food processor 100 during operation.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
