Description

Technical Field

[0001] This utility model belongs to the field of food processing, and specifically relates to a food processing device. Background Technology

[0002] Traditional food processing equipment often employs a structure where the motor is mounted inside the machine head. The output shaft of the motor's gearbox extends directly outside the machine head via mechanical means, forming a rigid coupling with the reamer to achieve reamer rotation and food chopping. However, this mechanical coupling method has significant drawbacks: the connection area between the machine head and the motor output shaft cannot be completely sealed due to the opening, preventing thorough removal of food residue by water rinsing during cleaning. Furthermore, the increased fluidity of lubricating grease during high-speed gear rotation makes it prone to leakage from the opening onto the food, potentially leading to serious food safety contamination. In addition, the inherent characteristics of mechanical coupling make the system susceptible to motor stalling and overheating when food resistance is excessive, threatening service life and safety. This stems from the fact that mechanical coupling requires physical contact and conduction, making effective isolation impossible. Therefore, an innovative design is urgently needed to eliminate the source of contamination and improve overall reliability, and this invention addresses this technical problem. Utility Model Content

[0003] In view of this, the present invention provides a food processing device that solves the technical problems of traditional equipment that cannot be thoroughly cleaned and affect food safety due to the use of mechanical coupling.

[0012] In some embodiments, the bottom of the container has an upwardly extending second support post, and the processing component cooperates with the second support post.

[0013] In some embodiments, the processing component includes a reamer; the magnetic coupling torque threshold between the drive coupler and the driven coupler is less than the maximum output torque of the drive component; when the resistance torque of the reamer exceeds the magnetic coupling torque threshold, the drive coupler and the driven coupler automatically decouple.

[0035] This embodiment provides a food processing device, such as... Figures 1-11 As shown, the food processing equipment includes a drive assembly 1, a container assembly 2, a power transmission assembly 3, and a processing assembly 4. The power transmission assembly 3 includes a drive coupler 31 and a driven coupler 32. The processing assembly 4 is located inside the container assembly 2. The drive coupler 31 is connected to the output end of the drive assembly 1, and the driven coupler 32 is connected to the processing assembly 4. The drive coupler 31 and the driven coupler 32 transmit torque in a non-contact magnetic coupling manner.

[0036] Drive assembly 1 serves as the rotational power source, providing the mechanical energy required for food processing. Container assembly 2 primarily functions to contain the food and support the internal structure. Processing assembly 4 directly acts on the food, performing the chopping function. Power transmission assembly 3 is a core improved component; its drive coupler 31 converts the mechanical rotation of drive assembly 1 into a changing magnetic field, while the driven coupler 32 receives this magnetic field and restores it to mechanical rotation. Their synergistic effect enables torque transmission across physical barriers in a non-contact manner. The functions of each component are interconnected; drive assembly 1 drives processing assembly 4 within container assembly 2 via power transmission assembly 3.

[0037] Drive assembly 1 is directly connected to drive coupler 31, which serves as the power source. Container assembly 2 forms the food-containing space and provides structural support. Processing assembly 4 is located inside container assembly 2 and is responsible for performing food processing operations. Power transmission assembly 3 consists of drive coupler 31 and driven coupler 32, with driven coupler 32 connected to processing assembly 4. Drive coupler 31 is located on the drive assembly 1 side, and driven coupler 32 is located on the processing assembly 4 side; they are spatially opposite each other in a non-contact manner, transmitting torque through magnetic field coupling when drive assembly 1 is operating. Throughout the system, there are no mechanical connection openings between drive assembly 1 and container assembly 2, or between drive coupler 31 and driven coupler 32; power transmission is achieved solely through magnetic coupling.

[0038] During operation, the drive assembly 1 drives the drive coupler 31 to rotate, and its permanent magnet generates a rotating magnetic field. This magnetic field penetrates the material barrier of the container assembly 2 and acts on the driven coupler 32, forcing it to rotate synchronously under magnetic force, thereby driving the processing assembly 4 to process the food. When the processing assembly 4 encounters excessive resistance, the magnetic coupling between the drive coupler 31 and the driven coupler 32 is overcome, and the driven coupler 32 will lag or even stop rotating, while the drive assembly 1 can continue to operate. At this time, power transmission is interrupted, the processing assembly 4 stops working, but there is no risk of the motor stalling. After the user removes the resistance, the coupler automatically resumes synchronous rotation.

[0039] This embodiment replaces the traditional mechanical perforation transmission with a non-contact magnetic coupling power transmission assembly 3, consisting of a drive coupler 31 and a driven coupler 32, fundamentally solving the two major problems of the prior art. More specifically, by eliminating the physical connection opening, the container assembly 2 forms a continuous closed structure, isolating the risk of lubricating oil leakage into food from the design source; at the same time, the overall sealing of the container assembly 2 provides a convenient basis for cleaning. Furthermore, the physical characteristics of magnetic coupling cause the drive coupler 31 and the driven coupler 32 to automatically disengage when the load exceeds the limit, and the power transmission is physically cut off, avoiding the problems of stalling, overheating, and burnout of the drive assembly 1. The entire solution relies on the core feature of magnetic transmission rather than mechanical contact.

[0040] In a specific embodiment, such as Figure 4 and Figure 5 As shown, both the driving coupler 31 and the driven coupler 32 include permanent magnet arrays, which include alternating N-pole permanent magnet blocks 311 and S-pole permanent magnet blocks 312.

[0041] Both the driving coupler 31 and the driven coupler 32 have a permanent magnet array as their core structure. This array consists of multiple N-pole permanent magnet blocks 311 and S-pole permanent magnet blocks 312 arranged in a regular pattern of alternating adjacent polarities. More specifically, in the permanent magnet array, every two adjacent permanent magnet blocks are arranged with alternating N and S poles. For example, an N-pole permanent magnet block 311 is necessarily adjacent to an S-pole permanent magnet block 312 to its right, and the next N-pole permanent magnet block 311 is to its right, forming a continuous alternating polarity sequence. This arrangement, based on the physical principle of magnetic field repulsion between opposite poles, directly produces three technical effects: First, when the drive coupler 31 and the driven coupler 32 approach each other, the alternating magnetic poles cause them to automatically find the magnetic field alignment position. That is, the N-pole permanent magnet 311 of the drive coupler 31 actively attracts the S-pole permanent magnet 312 of the driven coupler 32, while repelling adjacent N-pole permanent magnets 311, thereby achieving self-alignment coupling and reducing assembly precision requirements. Second, the staggered magnetic poles form a dense closed magnetic circuit, maximizing the magnetic field strength and coupling area per unit area, improving torque transmission efficiency. Third, the alternating magnetic field continuously generates a strong attractive force during relative rotation, ensuring that the drive coupler 31 and the driven coupler 32 maintain synchronous rotation under normal load. When the load exceeds a critical value, the slip between the magnetic poles increases until complete decoupling, physically cutting off load transmission and protecting the drive assembly 1 from stall damage. This feature optimizes the reliability and controllability of non-contact transmission through the physical design of the magnetic pole array.

[0042] In a specific embodiment, both the N-pole permanent magnet block 311 and the S-pole permanent magnet block 312 are segmented structures, and their shapes are one of circles, rectangles or fan shapes.

[0043] Each N-pole permanent magnet block 311 and S-pole permanent magnet block 312 in the drive coupler 31 and the driven coupler 32 adopts an independent physical block structure, that is, each magnetic pole is composed of a separate permanent magnet material block; and the shape of this block structure can be selected from circular, rectangular or fan-shaped. More specifically, the block design leaves gaps or non-magnetic intervals between each permanent magnet block, while the smooth edges of the circular magnetic blocks are conducive to the uniform distribution of the magnetic field; the rectangular magnetic blocks are easy to arrange compactly to increase the magnetic pole array density; the fan-shaped magnetic blocks are particularly suitable for the circumferential arrangement of rotating parts, and their arc surface is parallel to the direction of rotation to enhance the directional penetration of magnetic lines of force. This segmented structure, combined with shape optimization, produces three key effects: First, the segmented magnetic poles allow for more flexible arrangement and disperse mechanical stress, preventing structural breakage caused by centrifugal force generated during high-speed rotation of the monolithic magnetic ring. Second, specific shape optimization ensures a uniform distribution of the magnetic field on the coupler's working surface. For example, rectangles enhance the superposition efficiency of magnetic field strength between adjacent magnetic blocks, while fan-shaped shapes strengthen the tangential magnetic force along the rotational trajectory, thereby improving the stability of coupling torque transmission. Third, different shapes correspond to different process adaptability. Rectangular magnetic blocks are easy to machine for precise array arrangement, circular magnetic blocks have lower requirements for stamping dies, and fan-shaped magnetic blocks are easier to injection mold into rotating bodies, thus reducing manufacturing costs and ensuring yield. This embodiment solves the contradiction between optimizing magnet manufacturing processes and magnetic field performance through the combination of magnetic pole segmentation and shape selection.

[0044] In a specific embodiment, such as Figure 6 and Figure 7 As shown, the N-pole permanent magnet 311 and the S-pole permanent magnet 312 are made of neodymium iron boron or samarium cobalt, and their exteriors are covered with an elastic coating layer 313.

[0045] In this embodiment, each permanent magnet in the drive coupler 31 and the driven coupler 32 is made of neodymium iron boron (NdFeB) or samarium cobalt (SCo). More specifically, NdFeB is a powder metallurgy permanent magnet alloy composed of neodymium, iron, and boron, while SCo is a rare-earth permanent magnet alloy composed of samarium, cobalt, and other metals. Both materials possess significant permanent magnet characteristics and high energy product. This feature produces the following effects: First, NdFeB provides the highest energy product among current permanent magnets at room temperature, ensuring that the drive coupler 31 and the driven coupler 32 generate a strong magnetic field within a limited volume, thereby improving the torque transmission capacity per unit area. Second, SCo has excellent high-temperature stability, and its magnetic properties decay less in high-temperature working environments, preventing magnetic coupling failure due to heat generated during prolonged operation. Third, the high demagnetization resistance of both materials ensures that the coupler maintains stable magnetic output characteristics even under multiple overload slippage conditions, enhancing the service life and reliability of the power transmission component 3.

[0046] In addition, the N-pole permanent magnet 311 and the S-pole permanent magnet 312 are covered with an elastic coating layer, which can be a soft coating layer made of silicone. This silicone coating layer is tightly bonded to the surface of the permanent magnet through injection molding or bonding processes, forming an elastic buffer structure of uniform thickness. The elastic properties of silicone can effectively absorb the mechanical impact energy generated when the drive component 1 starts, stops, or vibrates, preventing the permanent magnet from cracking or being physically damaged under frequent slippage impacts; the silicone layer isolates the permanent magnet from contact with oxygen and water vapor, preventing the surface of easily oxidized materials such as neodymium iron boron from rusting, thereby avoiding magnetic attenuation caused by material oxidation; the coating layer forms a physical sealing barrier for the permanent magnet, completely preventing magnetic powder or debris from detaching from the N-pole permanent magnet 311 and the S-pole permanent magnet 312 under high-speed rotation and contaminating food, thus meeting food-grade safety protection requirements and improving the effectiveness of the contamination isolation technology solution.

[0047] In a specific embodiment, the drive assembly 1 includes a housing 11 and a drive motor 12, the drive motor 12 being disposed inside the housing 11, and the drive coupler 31 being fixed to the output shaft of the drive motor 12; wherein, the bottom of the housing 11 is a closed structure.

[0048] In this embodiment, the outer shell 11 serves as the outer housing of the drive assembly 1, providing a sealed and protective support for the drive motor 12 and ensuring that the internal components are isolated from the external environment. The drive motor 12 generates rotational mechanical power as a power source. The drive motor 12 is installed in the internal space of the outer shell 11, completely enclosing it within the shell structure. The output shaft of the drive motor 12 is directly mechanically fixed to the drive coupler 31, and the drive coupler 31 is rigidly connected to the output shaft of the drive motor 12 to form a torque transmission path. Overall, the outer shell 11, the drive motor 12, and the drive coupler 31 constitute an integrated unit.

[0049] The rotational output of the drive motor 12 is directly transmitted to the drive coupler 31 without intermediate losses, while the housing 11 encloses the drive motor 12 in a protected environment. This integrated structure reduces power transmission losses and improves energy utilization efficiency; furthermore, the housing 11 forms a physical barrier to prevent dust or moisture from entering the drive motor 12, ensuring the long-term reliable operation of the internal power source. As a result, the drive coupler 31, as the starting point of magnetic coupling, is fixedly positioned to ensure precise alignment with the driven coupler 32 during equipment operation, enhancing the stability and synchronization of non-contact transmission and supporting the overall sealed design goal.

[0050] More specifically, the bottom surface of the outer casing 11 forms a continuous, integrated barrier without any penetrating openings. The sealed bottom creates a permanent protective layer, completely preventing grease or food juices from seeping into the interior of the outer casing 11 and contaminating the drive motor 12 through external pathways, thus solving the contamination leakage problem of the prior art. In addition, the sealed structure strengthens the overall mechanical strength of the outer casing 11, preventing cracks or deformation during equipment assembly or vibration conditions, maintaining the long-term durability and hygienic safety characteristics of the drive component 1, and further improving the magnetic coupling isolation scheme.

[0051] In a specific embodiment, the container assembly 2 includes a container 21 and a cover 22, the cover 22 being able to cover the opening of the container 21; the joint between the cover 22 and the drive assembly 1 is provided with a waterproof sealing structure.

[0052] The food processing space is composed of a container 21 at the bottom for holding food and a detachable lid 22 at the top. The lid 22 closes the top opening of the container 21 by fastening or threading to form a complete cavity. An elastic sealing ring structure made of silicone or rubber is provided at the contact interface between the upper surface of the lid 22 and the lower surface of the drive assembly 1.

[0053] In this embodiment, the design of the container 21 and the lid 22 achieves a fully enclosed food processing process, preventing food debris or liquid from splashing and overflowing during stirring, thus ensuring a hygienic and safe environment. The waterproof sealing structure located at the joint surface between the lid 22 and the drive component 1 uses the elastic deformation of silicone to fill the gaps, completely blocking the risk of liquid seeping into the drive component 1 through the mechanical gaps, and more specifically solving the problem of external contaminants invading the power source in the prior art. In addition, the detachable design of the sealing structure, combined with the opening and closing function of the lid 22, makes it easy for users to thoroughly clean all food-contacting surfaces of the container component 2, thus more completely achieving the goal of equipment maintainability.

[0054] In a specific embodiment, such as Figure 1 and Figure 2 As shown, the top of the cover 22 has a recessed structure 23, and the bottom of the outer shell 11 has a downwardly extending protruding structure 13. The recessed structure 23 can accommodate the protruding structure 13 to achieve the cooperation between the drive assembly 1 and the container assembly 2.

[0055] When the drive assembly 1 is installed onto the container assembly 2, the protruding structure 13 automatically embeds into the inner cavity of the recessed structure 23, achieving physical positioning through the gap fit of the geometric contours. The protruding structure 13 precisely guides the assembly path of the outer shell 11 and the cover 22, ensuring that the rotation centers of the drive coupler 31 and the driven coupler 32 remain coaxial, avoiding magnetic field attenuation caused by magnetic pole misalignment due to assembly deviations. At the same time, the interlocking of the protruding and recessed structures creates a mechanical self-locking effect, effectively suppressing vibration displacement generated during high-speed operation of the equipment, maintaining a constant air gap distance between the drive coupler 31 and the driven coupler 32, and ensuring the continuous stability of magnetic flux transmission. This guiding design also simplifies the user's operation process; precise assembly can be completed simply by aligning the protruding structure 13 with the recessed structure 23, preventing permanent magnet block collision damage caused by human alignment errors from the source, and extending the service life of the equipment.

[0056] In a specific embodiment, such as Figure 2 As shown, the top of the cover 22 is provided with a first support column 221 extending downward, and the driven coupler 32 is fixed on the first support column 221.

[0057] This embodiment simplifies the spatial layout of the magnetic drive: the first support column 221, as a structural extension of the cover 22, suspends the driven coupler 32 inside the container 21 and maintains a rigid connection with the cover 22. This effectively solves the technical pain point of requiring additional supports to fix the driven component in traditional equipment. More specifically, the vertical extension characteristic of the first support column 221 ensures that the central axis of the driven coupler 32 is precisely aligned with the drive coupler 31. When the protruding structure 13 of the drive component 1 is embedded in the recessed structure 23 of the cover 22, the driven coupler 32 can automatically enter the magnetic field range of the drive coupler 31. At the same time, this integrated design significantly reduces the axial distance between the drive component and the working component, allowing the power transmission component 3 to achieve a more compact structural layout. This design also enhances the operational stability of the driven coupler 32. The rigid material of the first support column 221 can absorb the radial force generated by the rotating load, preventing the driven coupler 32 from radially swaying during high-speed rotation and ensuring that the magnetic coupling surface maintains a constant air gap.

[0058] In a specific embodiment, such as Figure 3 As shown, the bottom of the container 21 has an upwardly extending second support column 211, and the bottom of the processing component 4 cooperates with the second support column 211.

[0059] A second support column 211 extending vertically upwards is integrally formed at the bottom of container 21. The bottom of processing component 4 has a corresponding receiving structure, and the two are physically connected through snap-fit ​​or interference fit. This design directly constructs a stable support system for processing component 4 inside container 21: when the user places processing component 4, equipped with blades or stirring parts, into container 21, the second support column 211 automatically inserts into the mating groove or shaft hole at the bottom of processing component 4, forming a dual fixing effect of radial constraint and axial positioning. This effectively eliminates the radial sway problem caused by the cantilever structure of the working parts in traditional stirring equipment. When processing component 4 receives rotational power through magnetic coupling, the second support column 211 can absorb the lateral load formed by the stirring resistance of the food, preventing eccentric displacement of processing component 4. More specifically, this rigid support structure shortens the force transmission path from the driven coupler 32 to processing component 4, allowing rotational power to be directly transmitted from the power source to the working end, reducing power loss and vibration noise caused by an excessively long transmission chain. Meanwhile, the second support column 211 precisely controls the installation depth of the processing component 4 within the container 21, ensuring a constant gap between the blade and the bottom of the container 21. This prevents food from getting stuck and avoids metal-to-metal contact and wear. Furthermore, the detachable design of the second support column 211 and the processing component 4 simplifies the disassembly and assembly process. Users only need to lift the processing component 4 vertically to complete cleaning and maintenance without disassembling other transmission components, enhancing the ease of use and hygiene safety of the equipment.

[0060] In a specific embodiment, the processing component 4 includes a reamer; the magnetic coupling torque threshold between the drive coupler 31 and the driven coupler 32 is less than the maximum output torque of the drive component 1, and when the resistance torque of the reamer exceeds the magnetic coupling torque threshold, the drive coupler 31 and the driven coupler 32 automatically decouple.

[0061] In this embodiment, the processing component 4 is configured as a reamer, and the critical value of the magnetic coupling torque generated by the permanent magnets between the drive coupler 31 and the driven coupler 32 is limited to be lower than the maximum output torque of the drive motor 12. This technical solution forms a dynamic protection mechanism: when the reamer is cutting high-density food or encountering foreign objects, the working resistance torque will increase sharply. More specifically, once the resistance torque exceeds the preset magnetic coupling limit between the N-pole permanent magnet 311 and the S-pole permanent magnet 312, the driven coupler 32 will momentarily disengage from the drive coupler 31 under the action of magnetic repulsion. At this time, the drive motor 12 continues to idle, but the power transmission component 3 completely stops outputting torque. This directly produces a triple protection effect: First, it forcibly interrupts the reverse transmission of mechanical load to the drive source, completely avoiding the overheating and burnout of the windings of the drive motor 12 due to overload operation; second, it eliminates the risk of gear breakage or shaft breakage caused by overload impact in traditional hard-connected equipment; furthermore, when the resistance torque is reduced due to the removal of the obstruction, the drive coupler 31 and the driven coupler 32 can re-engage based on the automatic magnetic attraction characteristics of the N-pole permanent magnet block 311 and the S-pole permanent magnet block 312, realizing intelligent operation of equipment self-protection and function self-recovery.

[0062] The operation of the food processing equipment provided in this embodiment begins with the physical docking of the drive assembly 1 and the container assembly 2: the user aligns the protruding structure 13 at the bottom of the outer shell 11 with the recessed structure 23 at the top of the cover 22 and presses it down vertically. Self-correcting positioning is achieved through the gap fit of the geometric contours. At this time, the drive coupler 31, whose output shaft is fixed, and the driven coupler 32 are precisely coaxial on the vertical axis. When the drive motor 12 is started, the permanent magnet of the drive coupler 31 generates a rotating magnetic field. This magnetic field penetrates the cover 22 and acts on the permanent magnet of the driven coupler 32, causing the driven coupler 32, fixed on the first support column 221, to rotate synchronously. More specifically, the driven coupler 32 transmits torque to the processing assembly 4 supported by the second support column 211, driving a rotating component, such as a reamer, to cut the food. When the resistance torque of the processing component 4 exceeds the magnetic coupling torque threshold between the drive coupler 31 and the driven coupler 32, the driven coupler 32 overcomes the magnetic attraction and automatically disengages from the drive coupler 31. At this time, the drive motor 12 idles while the processing component 4 stops operating. If the resistance torque decreases, the two will re-establish magnetic coupling. Furthermore, throughout the entire working cycle, the mechanical interlock formed by the protruding structure 13 and the recessed structure 23 suppresses vibration displacement, the first support column 221 ensures the rotational stability of the driven coupler 32, and the second support column 211 eliminates the sway caused by cutting reaction force by radially constraining the processing component 4. This cooperative mechanism continuously ensures the stability of magnetic force transmission until the user removes the drive component 1 to terminate power transmission.

[0063] The food processing equipment provided in this embodiment can be a meat grinder or other food processing equipment.

[0064] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.
