Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to 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. These food processors use the magnetic force between the upper and lower magnets to drive the mixing device to rotate and blend ingredients. However, when it's time to remove the blender cup after preparation, the magnetic force between the upper and lower magnets makes it difficult to remove the cup.

[0003] Therefore, how to develop a food processor with magnetic drive and an easily removable food processing cup has become an urgent problem to be solved. Utility Model Content

[0004] The present invention aims to at least solve the technical problem that the food processing cup of a magnetically driven food processor is not easy to remove in the prior art or related technologies.

[0005] The first objective of this invention is to provide a food processing machine.

[0006] To achieve the above objectives, embodiments of this utility model provide a food processor, comprising: a base; a mixing cup disposed on the base; a mixing device rotatably mounted inside the mixing cup; a driving device for providing power to the mixing device; a magnetic transmission component connected to the driving device and capable of rotating under the action of the driving device; a passive component rotatably disposed in the mixing cup and connected to the mixing device to drive the mixing device to rotate; wherein, the passive component includes a non-magnetic conductive component, which, when the magnetic transmission component rotates, can induce a magnetic field under the action of the magnetic field generated by the magnetic transmission component, and the magnetic transmission component can drive the passive component to rotate under the action of the induced magnetic field and the magnetic field generated by the magnetic transmission component; and a heat dissipation device disposed in the mixing cup for dissipating heat from the passive component.

[0007] The food processor according to an embodiment of this utility model includes a base, a mixing cup, a mixing device, a drive device, a magnetic transmission component, a passive component, and a heat dissipation device. The base is the main unit of the machine. The mixing cup is detachably mounted on the base and is used to hold and process food ingredients. The mixing device is rotatably mounted inside the mixing cup for mixing the food ingredients. The drive device is mounted on the base and provides driving force to drive the mixing device to rotate. The magnetic transmission component is rotatably mounted on the base and connected to the drive device, and can rotate under the drive device's influence. The passive component is rotatably mounted on the mixing cup and connected to the mixing device to drive its rotation; it includes a non-magnetic conductive component. During operation, the drive device drives the magnetic transmission component to rotate, generating a changing magnetic field. This changing magnetic field acts on the conductive component in the passive component, inducing eddy currents and generating an induced magnetic field. The magnetic transmission component interacts with the induced magnetic field, generating torque, thereby driving the passive component and the mixing device to rotate synchronously, achieving non-contact transmission. The heat dissipation device is installed on the stirring cup. The heat dissipation device actively dissipates heat from the passive component that generates heat due to the eddy current effect during high-speed rotation through convection or conduction, thereby preventing the passive component from overheating.

[0008] Power is transmitted via a non-contact magnetic drive, making the blender cup easy to disassemble and clean, and ensuring smoother operation throughout the product. A dedicated heat dissipation device effectively suppresses temperature rise caused by eddy currents, improving transmission efficiency and long-term reliability. Furthermore, because the passive component is made of a non-magnetic material, the magnetic drive component remains stationary when the food processor is not in operation, eliminating axial attraction between the magnetic drive component and the passive component. Users do not need to overcome the magnetic pull when removing the blender cup, making disassembly and cleaning extremely easy and convenient.

[0009] The driving device is an electric motor.

[0010] Optionally, the magnetic transmission component includes a fixing member and magnets mounted on the fixing member. The magnets may specifically be permanent magnets, etc. The fixing member can provide a mounting platform for multiple magnets.

[0011] Optionally, in any of the above technical solutions, the heat dissipation device includes: a heat dissipation fan blade, which is disposed on the passive member and can rotate under the action of the passive member.

[0012] In these technical solutions, when the driving device drives the stirring device to rotate via magnetic transmission components and a driven component, the cooling fan blades rotating along with the driven component generate forced airflow, directly and efficiently cooling the conductive components that generate heat due to the eddy current effect. By using the cooling fan blades mounted on the driven component and leveraging the rotational power of the transmission system itself to drive the cooling fan blades, no additional drive structure is required. This not only effectively controls the temperature rise problem in eddy current transmission and simplifies the structure but also improves the stability of the transmission and the durability of the components.

[0013] In any of the above technical solutions, optionally, the conductive component is located at the bottom outer side of the mixing cup, and the heat dissipation fan is disposed on the side of the conductive component near the bottom of the mixing cup.

[0014] In these technical solutions, the conductive component is mounted on the outside of the mixing cup and located at the bottom of the mixing cup. The cooling fan is positioned at the bottom of the conductive component, meaning it can rotate below the conductive component to drive the airflow below it, thereby dissipating heat from the conductive component. By designing the cooling fan close to the bottom of the mixing cup, the conductive component can be brought closer to the magnetic transmission component, ensuring unobstructed magnetic fields between them, thus improving the overall torque transmission efficiency of the product.

[0015] In this design, the passive component is directly fixed to the stirring device. When stirring ingredients, there is water in the stirring cup, and the stirring device is generally made of metal. The water in the stirring cup will absorb heat from the passive component through the stirring device, thereby reducing the temperature of the passive component. By placing the heat dissipation fan blades close to the stirring cup, the airflow between the stirring cup and the passive component can be made to flow faster, so that the airflow can absorb more heat from the passive component to transfer to the stirring device, thereby improving the heat dissipation of the passive component.

[0016] In any of the above technical solutions, the passive component may optionally include: a bracket rotatably mounted on the mixing cup, and conductive components and heat dissipation fan blades mounted on two opposite sides of the bracket along the height direction of the mixing cup.

[0017] In these technical solutions, the passive component includes a support and a conductive component. The support is used to support and install the conductive component, ensuring the connection strength between the passive component and the stirring device. By using a support, the material used for the conductive component can be reduced, thus lowering the cost of the passive component. For example, the conductive component can be made of highly conductive materials such as copper or aluminum, while the support can be made of inexpensive materials such as plastic or stainless steel. Using plastic for the support reduces the weight of the passive component, while using stainless steel increases the temperature resistance and structural strength of the passive component.

[0018] During installation, the conductive components and heat dissipation fan blades are installed on opposite sides of the bracket along the height of the mixing cup. This allows for a layered layout of the heat-conducting components and heat dissipation fan blades in the height direction, ensuring magnetic transmission efficiency while significantly improving heat dissipation performance by increasing the heat dissipation area and optimizing the airflow path.

[0019] For example, the conductive component is mounted on the lower side of the bracket, and the heat dissipation fan is mounted on the upper side of the bracket.

[0020] In any of the above technical solutions, optionally, the heat dissipation fan blades and the bracket are an integral structure, and / or the conductive parts are welded or glued to the bracket.

[0021] In these technical solutions, the integrated design of the cooling fan blades and the bracket eliminates assembly errors between the cooling fan blades and the bracket, ensures dynamic balance accuracy, reduces vibration and noise when the passive component rotates at high speed, and improves the structural strength and heat dissipation efficiency of the passive component. Secondly, the conductive component and the bracket are firmly connected by welding or gluing, which not only ensures the effective transmission of transmission torque and avoids relative slippage or detachment, but also optimizes the heat conduction path, so that the heat generated by the conductive component can be quickly transferred to the cooling fan blades through the bracket, significantly improving the overall heat dissipation performance.

[0022] Optionally, the cooling fan blades include multiple blades, which are spaced apart on the support along the rotation direction of the stirring device.

[0023] In any of the above technical solutions, optionally, the heat dissipation device is a ventilation groove provided on the passive component, and the ventilation groove passes through the passive component along the height direction of the stirring cup.

[0024] In these technical solutions, by setting up ventilation slots, the passive component can be passed through along the height direction. This allows the heat above the passive component to flow through the ventilation slots to the bottom of the passive component and dissipate in time, preventing heat from accumulating between the stirring cup and the passive component and being unable to dissipate. This improves the overall heat dissipation effect of the heat dissipation device on the passive component.

[0025] Optionally, any ventilation slot may be located between any two adjacent blades.

[0026] In any of the above technical solutions, the passive component may optionally be a disc-shaped structure. A drive shaft is installed in the middle of the disc-shaped structure to facilitate the connection between the passive component and the stirring device.

[0027] Optionally, in any of the above technical solutions, the ventilation slot penetrates the conductive component.

[0028] In these technical solutions, each ventilation slot passes through a conductive component, meaning that the conductive component also has corresponding through holes. By providing through holes in the conductive component, the discontinuity of the conductive component can be increased, the eddy current path can be lengthened, and the effective conductive area of ​​the conductive component can be reduced, thereby increasing the overall resistance and reducing losses caused by eddy current heating. For example, when the conductive component is a ring structure, the magnitude of the magnetic field is related to the outer diameter and area of ​​the ring structure. By providing through holes, the area of ​​the conductive component can be reduced without reducing the outer diameter, thereby reducing the resistance of the conductive component and reducing its losses.

[0029] In any of the above technical solutions, optionally, the passive component includes multiple segmented units arranged at intervals along the circumference of the stirring device, the conductive component includes multiple sub-conductive parts, the multiple sub-conductive parts are arranged one-to-one on the multiple segmented units, and the ventilation groove is the interval formed between adjacent segmented units.

[0030] In these technical solutions, both the passive and conductive components are modular structures. This modular design allows for ventilation gaps between adjacent modules, enabling heat above the passive component to flow to the area below and dissipate quickly. This prevents heat from accumulating between the stirring cup and the passive component, thus improving the overall heat dissipation effect of the cooling system.

[0031] Among them, the passive component and the conductive component are segmented structures. This is a special case where ventilation slots are set on the passive component. That is, the ventilation slots are distributed in the entire radial direction of the passive component, thereby dividing the passive component into multiple independent segmented units.

[0032] Optionally, in any of the above technical solutions, the food processor may further include: a drive shaft, which is rotatably mounted on the mixing cup and connected to the mixing device and the passive component.

[0033] In these technical solutions, the drive shaft facilitates the connection between the stirring device and the driven component. The drive shaft can be a metal shaft, which ensures its strength. At the same time, the metal shaft can also transfer heat from the driven component to the interior of the stirring cup, thereby achieving heat dissipation through the liquid inside the stirring cup.

[0034] Optionally, in any of the above technical solutions, a gap may be provided between the magnetic transmission component and the passive component.

[0035] In these technical solutions, the presence of gaps enables non-contact transmission between the magnetic drive components and the driven components, eliminating mechanical wear and friction noise between them, and significantly improving the service life of the transmission components and the overall noise reduction performance. Secondly, the reasonable gap design not only ensures the magnetic field coupling efficiency and guarantees sufficient torque transmission to the stirring device, but also provides unobstructed flow space for the cooling airflow generated by the rotation of the cooling fan blades, enhancing the heat dissipation effect on the driven components. Finally, the gaps allow for quick separation and installation of the stirring cup and the base, greatly facilitating the user's cleaning and maintenance operations.

[0036] Alternatively, the food processor can be a high-speed blender or a juicer.

Detailed Implementation

[0046] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] The following reference Figures 1 to 5 This application describes the food processing machine provided in the embodiments of the present application.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of this utility model provides a food processor, including a base 1, a mixing cup 2, a mixing device 3, a driving device 4, a magnetic transmission component 5, a passive component 6, and a heat dissipation device 7. The mixing cup 2 is mounted on the base 1. The mixing device 3 is rotatably mounted inside the mixing cup 2. The driving device 4 is mounted on the base 1 and provides power to the mixing device 3. The magnetic transmission component 5 is connected to the driving device 4 and can rotate under the action of the driving device 4. The passive component 6 is rotatably mounted on the mixing cup 2 and connected to the mixing device 3 to drive the mixing device 3 to rotate; wherein, the passive component 6 includes a non-magnetic conductive component 62. When the magnetic transmission component 5 rotates, the conductive component 62 can induce an induced magnetic field under the action of the magnetic field generated by the magnetic transmission component 5, and the magnetic transmission component 5 can drive the passive component 6 to rotate under the action of the induced magnetic field and the magnetic field generated by the magnetic transmission component 5; the heat dissipation device 7 is disposed on the mixing cup 2 for dissipating heat from the passive component 6.

[0050] The food processor according to an embodiment of this utility model includes a base 1, a mixing cup 2, a mixing device 3, a drive device 4, a magnetic transmission component 5, a passive component 6, and a heat dissipation device 7. The base 1 is the main unit of the machine. The mixing cup 2 is mounted on the base 1 and is used to hold and process food ingredients. The mixing device 3 is rotatably mounted inside the mixing cup 2 for mixing the food ingredients. The drive device 4 is mounted on the base 1 and provides driving force to drive the mixing device 3 to rotate. The magnetic transmission component 5 is connected to the drive device 4 and can rotate under the drive of the drive device 4. The passive component 6 is rotatably mounted on the mixing cup 2 and connected to the mixing device 3 to drive its rotation. It includes a non-magnetic conductive component 62. During operation, the drive device 4 drives the magnetic transmission component 5 to rotate, generating a changing magnetic field. The changing magnetic field acts on the conductive component 62 in the passive component 6, inducing eddy currents and generating an induced magnetic field. The magnetic transmission component 5 interacts with the induced magnetic field, generating torque, thereby driving the passive component 6 and the mixing device 3 to rotate synchronously, achieving non-contact transmission. The heat dissipation device 7 is installed on the stirring cup 2. The heat dissipation device 7 actively dissipates heat from the passive component 6, which generates heat due to the eddy current effect during high-speed rotation, through convection or conduction, to prevent the passive component 6 from overheating.

[0051] Power is transmitted via a non-contact magnetic drive, making the blending cup 2 easy to disassemble and clean, and ensuring smoother operation throughout the product. A dedicated heat dissipation device 7 effectively suppresses temperature rise caused by eddy currents, improving transmission efficiency and long-term reliability. Furthermore, because the passive component 6 is made of a non-magnetic material, the magnetic transmission component 5 remains stationary when the food processor is not in operation. No axial attraction is generated between the magnetic transmission component 5 and the passive component 6, eliminating the need for users to overcome the magnetic force when removing the blending cup 2, making disassembly and cleaning extremely easy and convenient.

[0052] Optionally, the magnetic drive component 5 is rotatably mounted on the base 1. Optionally, the stirring cup 2 is detachably mounted on the base 1.

[0053] Among them, the driving device 4 is a motor.

[0054] Optionally, such as Figure 2 As shown, the magnetic transmission component 5 includes a fixing member 52 and magnets mounted on the fixing member 52. The magnets may specifically be permanent magnets 54, etc. The fixing member 52 can provide a mounting platform for multiple magnets.

[0055] In any of the above embodiments, optionally, as Figure 3 As shown, the heat dissipation device 7 includes a heat dissipation fan blade 72, which is disposed on the passive member 6 and can rotate under the action of the passive member 6.

[0056] In these embodiments, when the driving device 4 drives the stirring device 3 to rotate via the magnetic transmission component 5 and the passive component 6, the cooling fan 72, which rotates together with the passive component 6, generates a forced airflow to directly and efficiently cool the conductive component 62, which is heated by the eddy current effect. By utilizing the rotational power of the transmission system itself to drive the cooling fan 72, which is mounted on the passive component 6, no additional drive structure is required. This not only effectively controls the temperature rise problem in eddy current transmission and simplifies the structure but also improves the stability of the transmission and the durability of the components.

[0057] In any of the above embodiments, optionally, as Figure 1 and Figure 2 As shown, the conductive component 62 is located at the bottom outer side of the stirring cup 2, and the heat dissipation fan 72 is disposed on the side of the conductive component 62 near the bottom of the stirring cup 2.

[0058] In these embodiments, the conductive element 62 is mounted on the outside of the stirring cup 2 and located at the bottom of the stirring cup 2. A heat dissipation fan 72 is disposed at the bottom of the conductive element 62, meaning the heat dissipation fan 72 can rotate below the conductive element 62 to drive the airflow below the heat dissipation fan 72, thereby achieving heat dissipation for the conductive element 62, etc. By designing the heat dissipation fan close to the bottom of the stirring cup 2, the conductive element 62 can be brought closer to the magnetic transmission element 5, thus ensuring unobstructed magnetic fields between the two, thereby improving the torque transmission efficiency of the entire product.

[0059] In this design, the passive component 6 is directly fixed to the stirring device 3. When stirring ingredients, there is water in the stirring cup 2, and the stirring device 3 is generally a metal part. The water in the stirring cup will absorb heat from the passive component 6 through the stirring device 3, thereby reducing the temperature of the passive component 6. By placing the heat dissipation fan 72 close to the stirring cup 2, the airflow between the stirring cup 2 and the passive component 6 can be made to flow faster, so that the airflow can absorb more heat from the passive component 6 to transfer to the stirring device 3, thereby improving the heat dissipation of the passive component 6.

[0060] In any of the above embodiments, optionally, as Figure 3 , Figure 4 and Figure 5 As shown, the passive component 6 includes a bracket 64 and a conductive component 62. The bracket 64 supports and mounts the conductive component 62, ensuring the connection strength between the passive component 6 and the stirring device 3. By using the bracket 64, the material used for the conductive component 62 can be reduced, thus lowering the cost of the passive component 6. For example, the conductive component 62 can be made of a material with high conductivity such as copper or aluminum, while the bracket 64 can be made of inexpensive materials such as plastic or stainless steel. Using plastic for the bracket 64 can reduce the weight of the passive component 6, while using stainless steel can increase the temperature resistance of the passive component 6 and improve its structural strength.

[0061] During installation, the conductive component 62 and the heat dissipation fan blade 72 are installed on opposite sides of the bracket 64 along the height direction of the stirring cup 2. This allows for a layered layout of the heat-conducting component and the heat dissipation fan blade in the height direction, ensuring magnetic transmission efficiency while significantly improving heat dissipation performance by increasing the heat dissipation area and optimizing the airflow path.

[0062] For example, the conductive element 62 is mounted on the lower side of the bracket 64, and the heat dissipation fan 72 is mounted on the upper side of the bracket 64.

[0063] In any of the above embodiments, optionally, the heat dissipation fan 72 and the bracket 64 are an integral structure, and / or the conductive element 62 is welded or glued to the bracket 64.

[0064] In these embodiments, the integrated design of the heat dissipation fan 72 and the bracket 64 eliminates assembly errors between the heat dissipation fan 72 and the bracket 64, ensures dynamic balance accuracy, reduces vibration and noise when the passive component 6 rotates at high speed, and improves the structural strength and heat dissipation efficiency of the passive component 6. Secondly, the conductive component 62 and the bracket 64 are firmly connected by welding or adhesive, which not only ensures the effective transmission of transmission torque and avoids relative slippage or detachment, but also optimizes the heat conduction path, so that the heat generated by the conductive component 62 can be quickly transferred to the heat dissipation fan 72 through the bracket 64, significantly improving the overall heat dissipation performance.

[0065] Optionally, the heat dissipation fan 72 includes multiple blades, which are spaced apart on the bracket 64 along the rotation direction of the stirring device 3.

[0066] In any of the above embodiments, optionally, as Figures 3 to 5 As shown, the heat dissipation device 7 is a ventilation groove 74 provided on the passive member 6, and the ventilation groove 74 penetrates the passive member 6 along the height direction of the stirring cup 2.

[0067] In these embodiments, by providing ventilation slots 74, the passive component 6 can be made to pass through along the height direction. This allows the heat above the passive component 6 to flow through the ventilation slots 74 to the bottom of the passive component 6 and dissipate in time, preventing heat from accumulating between the stirring cup 2 and the passive component 6 and being unable to dissipate. This improves the overall heat dissipation effect of the heat dissipation device 7 on the passive component 6.

[0068] Optionally, any ventilation slot 74 may be located between any two adjacent blades.

[0069] In any of the above embodiments, optionally, as Figures 3 to 5 As shown, the passive component 6 has a disc-shaped structure. A drive shaft 8 is installed in the middle of the disc-shaped structure to facilitate the connection between the passive component 6 and the stirring device 3.

[0070] In any of the above embodiments, the ventilation slot 74 optionally penetrates the conductive element 62.

[0071] In these embodiments, each ventilation slot 74 passes through the conductive element 62, meaning that the conductive element 62 also has a corresponding through hole. By providing through holes in the conductive element 62, the discontinuity of the conductive element 62 can be increased, the eddy current path can be lengthened, and the effective conductive area of ​​the conductive element 62 can be reduced, thereby increasing the overall resistance and reducing the loss caused by eddy current heating. For example, when the conductive element 62 is a ring structure, the magnitude of the magnetic field is related to the outer diameter and area of ​​the ring structure. By providing through holes, the area of ​​the conductive element 62 can be reduced without reducing the outer diameter, thereby reducing the resistance of the conductive element 62 and reducing the loss of the conductive element 62.

[0072] In any of the above embodiments, optionally, as Figure 5 As shown, the passive component 6 includes multiple segmented units 66 spaced circumferentially along the stirring device 3, and the conductive component 62 includes multiple sub-conductive parts 622, which are correspondingly disposed on the multiple segmented units 66. The ventilation slot 74 is the interval formed between adjacent segmented units 66.

[0073] In these embodiments, both the passive component 6 and the conductive component 62 are modular structures. This modular design allows for ventilation gaps between adjacent modular structures, enabling heat above the passive component 6 to flow through these gaps to the area below, dissipating promptly and preventing heat buildup between the stirring cup 2 and the passive component 6. This improves the overall heat dissipation effect of the heat dissipation device 7 on the passive component 6.

[0074] Among them, the passive component 6 and the conductive component 62 are segmented structures. This is a special case where ventilation slots 74 are set on the passive component 6. That is, the ventilation slots 74 are distributed in the entire radial direction of the passive component 6, thereby dividing the passive component 6 into multiple independent segmented units 66.

[0075] In any of the above embodiments, optionally, as Figures 1 to 3 As shown, the food processor also includes: a drive shaft 8, which is rotatably mounted on the mixing cup 2 and connected to the mixing device 3 and the passive component 6.

[0076] In these embodiments, the drive shaft 8 facilitates the connection between the stirring device 3 and the driven component 6. The drive shaft 8 can be a metal shaft, which ensures the strength of the drive shaft 8. At the same time, the metal shaft can also transfer heat from the driven component 6 to the interior of the stirring cup 2, so as to achieve heat dissipation through the liquid inside the stirring cup 2.

[0077] In any of the above embodiments, optionally, as Figure 1 As shown, a gap d is provided between the magnetic transmission component 5 and the passive component 6.

[0078] In these embodiments, the presence of the gap enables non-contact transmission between the magnetic transmission component 5 and the driven component 6, eliminating mechanical wear and friction noise between them, and significantly improving the service life of the transmission components and the overall noise reduction performance. Secondly, the reasonable gap design ensures both the magnetic field coupling efficiency, guaranteeing sufficient torque transmission to the stirring device 3, and provides a smooth flow channel for the cooling airflow generated by the rotation of the cooling fan blades 72, enhancing the heat dissipation effect on the driven component 6. Finally, the gap allows for quick separation and installation of the stirring cup 2 and the base 1, greatly facilitating the user's cleaning and maintenance operations.

[0079] Alternatively, the food processor can be a high-speed blender or a juicer.

[0080] The following describes a food processor in a specific embodiment.

[0081] 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. These food processors use the magnetic force between the upper and lower magnets to drive the mixing device 3 to rotate, thus blending the ingredients. However, when it's time to remove the blending cup after the food is prepared, the magnetic force between the upper and lower magnets makes it difficult to remove the blending cup.

[0082] This embodiment provides a planar eddy current magnetic drive blender to achieve non-contact transmission of kinetic energy and to facilitate users in removing the mixing cup for cleaning.

[0083] like Figures 1 to 5As shown, the planar eddy current magnetic drive blender provided in this embodiment includes a mixing cup assembly and a main unit (mainly including a base 1 and a drive device 4). The main unit is equipped with a motor and a first transmission component (magnetic transmission component 5); the first transmission component includes a fixed base and a permanent magnet 54, with the permanent magnet 54 fixed on the fixed base and the first transmission component mounted on the motor. The mixing assembly is equipped with a second transmission component (including a driven component 6 and a drive shaft 8), a blade shaft, and a pulverizing blade (mixing device 3), etc. The second transmission component is mounted on the blade shaft. A gap is provided between the first transmission component and the second transmission component, the size of which is d, where 0 < d. After the machine is powered on and the starting function is activated, the motor drives the permanent magnet 54 to rotate at high speed via the first transmission component. A second transmission component, containing a conductor (such as copper or aluminum, which have high conductivity), is positioned above the permanent magnet 54. Due to electromagnetic induction, eddy currents are generated within the second transmission component. These eddy currents produce a magnetic field opposite to that of the permanent magnet 54. This opposing magnetic field interacts with the permanent magnet 54's magnetic field, generating electromagnetic torque, which in turn drives the second transmission component to rotate synchronously. The second transmission component then drives the blade shaft and pulverizing blades, thus achieving the purpose of pulverizing food. Throughout the process, there is no direct contact between the permanent magnet 54 and the conductor, achieving non-contact transmission. Because the second transmission component is made of a non-magnetic material, when the machine is not in operation, the permanent magnet 54 is stationary and does not generate axial attraction with the first transmission component, making it easy for the user to remove the mixing cup assembly. The high-speed rotation of the permanent magnet 54 generates eddy currents within the second transmission component, which produce heat. During prolonged operation, the operating temperature of the second transmission component will be very high, making heat dissipation necessary. The second transmission component is directly fixed to the blade shaft and the pulverizing blade. Since there is water in the mixing cup when pulverizing food, and the blade shaft and pulverizing blade are made of metal, the water in the mixing cup will absorb heat from the second transmission component through the pulverizing blade and the blade shaft, thereby reducing the temperature of the second transmission component.

[0084] Optionally, during machine operation, eddy currents are generated inside the second transmission component when the permanent magnet 54 rotates at high speed. These eddy currents generate heat, and the operating temperature of the second transmission component will be very high if the operation time is long. To dissipate heat from the second transmission component, a cooling fan 72 is installed on the back of the second transmission component. When the motor drives the permanent magnet 54 to rotate the second transmission component, the high-speed rotation of the cooling fan 72 causes the air near the second transmission component to flow rapidly, thereby quickly and efficiently dissipating heat from the second transmission component. The higher the motor speed, the larger the eddy current, and the more heat is generated. Because the second transmission component also rotates at a high speed, the cooling fan 72 dissipates heat even more quickly.

[0085] Optionally, during machine operation, when the permanent magnet 54 rotates at high speed, eddy currents are generated inside the second transmission component. These eddy currents generate heat, leading to eddy current losses. According to the law of conservation of energy, this reduces the transmission efficiency of the motor's kinetic energy. Therefore, several through-groove structures (ventilation slots 74) are provided on the surface of the second transmission component. These groove structures allow the second transmission component to run vertically, facilitating airflow and improving heat dissipation. The groove structures also increase the discontinuity of the conductor, lengthening the eddy current path while reducing the effective conductive area and increasing the overall resistance, thereby reducing losses caused by eddy current heating.

[0086] Optionally, the second transmission component includes several conductors and a transmission shaft 8. The conductors are evenly distributed around the transmission shaft 8, dividing the whole into N small blocks, ensuring the overall conductivity while restricting the flow of eddy currents within the second transmission component. Each conductor, under the action of high-speed rotation, can also act as a heat dissipation fan 72 to dissipate heat from itself.
