Detailed Implementation To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0014] Currently, with the accelerating pace of modern life and increasingly compact living spaces, consumer demand for kitchen appliances is showing a trend towards integration, multi-functionality, and intelligence. However, most existing small kitchen appliances on the market, such as juicers, meat grinders, and egg beaters, often have single functions, requiring a separate device for each specific cooking task. This "one machine, one function" model not only leads to users needing to purchase multiple devices, resulting in considerable economic expenses, but also makes the kitchen space feel cramped due to a large number of small appliances with highly repetitive functions, contradicting the modern home's pursuit of simplicity and efficiency. Users urgently need a modular solution that can integrate multiple commonly used cooking functions, achieving multi-purpose functionality, to save space, improve efficiency, and optimize the user experience. Based on the research and development background of addressing the above-mentioned technical pain points, this utility model provides a modular food processor solution.

[0015] Example 1: This embodiment provides a drive device for a modular food processor. This drive device is the core foundation of this utility model and aims to provide a power source that has multiple standardized interfaces, is safe and reliable, and is easy to assemble.

[0016] Please see the appendix Figures 1 to 4 The drive device in this embodiment has a basic structure including a housing 1, a built-in drive motor 2, an assembly plate 3, a first docking structure 4, a second docking structure 5, and a protection switch 6. In addition, in order to form a complete functional unit, the drive device also integrates conventional electrical components, such as a main control circuit board, a charging interface, and a battery pack that powers the drive motor 2.

[0017] The housing 1, serving as the load-bearing foundation and outer casing of the entire drive unit, is typically injection molded from engineering plastics such as ABS or PC to ensure sufficient structural strength and good electrical insulation performance. The housing 1 contains an internal space for mounting the drive motor 2 and related electrical components. The drive motor 2 is the power source and can be a high-speed DC motor, AC motor, geared motor, etc. Its motor shaft has a power output interface 21 at its end. This power output interface 21 can be a splined shaft, a polygonal bushing, or a shaft hole with a keyway, etc., for reliable torque transmission to the drive shaft of external functional devices.

[0018] The bottom of housing 1 has an open port, to which an assembly plate 3 is securely mounted using screws or clips. This assembly plate 3, also made of high-strength engineering plastic or metal, serves both as a cover for the bottom of housing 1 and as a highly integrated interface platform. A first through-hole 31 is located at the center of the assembly plate 3. This first through-hole 31 is precisely aligned with the power output interface 21 of the drive motor 2, providing a channel for the drive shaft of an external functional device to pass through and connect to the power output interface 21.

[0019] The core of the driving device in this embodiment lies in its two different types of interfaces. On the assembly plate 3, around the first through hole 31, a first mating structure 4 for precise positioning and assembly is provided. Simultaneously, on the bottom edge of the housing 1, such as its inner wall, a second mating structure 5 for quick assembly and fixation is also provided. These two different types of mating structures enable this driving device to adapt to and drive at least two different external functional devices, greatly expanding its versatility.

[0020] To ensure safe operation, a safety interlock mechanism is integrated into the drive unit. Specifically, a standard microswitch, acting as a protective switch 6, is fixedly installed inside the drive unit on the back of the mounting plate 3. This protective switch 6 is electrically connected in series with the main power supply circuit of the drive motor 2 and is itself a normally open contact. The protective switch 6 has a slender trigger part 61 with sufficient mechanical strength. This trigger part 61 passes through a pre-drilled hole on the mounting plate 3, and its end extends precisely into the effective area of ​​the first mating structure 4. Its working principle is as follows: only when the external functional device and the first mating structure 4 are geometrically completely and correctly installed will a specially designed corresponding physical structure on the functional device accurately press or actuate the trigger part 61, closing the internal contacts of the microswitch and thus connecting the power supply to the drive motor 2. In any case of non-installation, improper installation, or incorrect installation, the trigger part 61 will not be activated, the motor's main circuit remains open, and the motor will not start even if the user accidentally presses the start button. This purely electromechanical interlocking mechanism offers higher reliability and safety compared to software control, effectively eliminating the risk of equipment damage or personal injury that may result from misoperation.

[0021] Furthermore, as a preferred embodiment, please refer to the appendix. Figures 5 to 9 The first docking structure 4 is specifically manifested as a first annular groove 41 coaxially formed on the assembly plate 3. The center of the first annular groove 41 coincides with the axis of the first through hole 31. This coaxial arrangement ensures that the external functional device can automatically align with the center during docking, facilitating the smooth insertion of the drive shaft. Simultaneously, directly above the trigger part 61 of the aforementioned protective switch 6, a second through hole 42 is formed at the bottom of the first annular groove 41. The trigger part 61 extends out of this second through hole 42 and is exposed within the groove, slightly protruding from the bottom plane of the groove. Thus, when the annular protrusion of the functional device is inserted into the first annular groove 41, it can easily press against the trigger part 61, triggering the safety signal.

[0022] Furthermore, to achieve precise circumferential positioning and efficient torque transmission, multiple axial limiting grooves 43 are uniformly arranged circumferentially on the inner wall or bottom surface of the first annular groove 41. These axial limiting grooves 43 are used to cooperate with the limiting ribs on the functional device. Once engaged, they prevent relative rotation between the two, ensuring that the torque output by the motor can be transmitted to the functional device without loss. Alternatively, the circumferential limiting structure here can also be an equivalent structure well known to those skilled in the art, such as a spline, pin, or pin groove.

[0023] Furthermore, as an optional implementation, to accommodate functional devices with higher requirements for structural stability and installation rigidity, such as stirring paddles or dough hooks that need to withstand large lateral torques, the interface platform of this drive device can also provide an additional positioning and support structure. Specifically, a second annular groove 44 is coaxially formed around the outer periphery of the first annular groove 41, between its outer wall and the inner wall of the housing 1. The machining depth, width, and roundness of the second annular groove 44 are precisely controlled, forming a double concentric ring structure with the first annular groove 41. The core function of the second annular groove 44 is to provide a large radial positioning reference and a stable axial support surface for a matching connection structure on the external functional device. Through this double annular groove design, the contact between the functional device and the drive device and the diameter of the support base are significantly enlarged, thereby greatly enhancing the anti-overturning ability and overall structural rigidity after the two are combined. It can effectively resist vibration and swaying caused by uneven ingredients or high loads during operation, ensuring stable and reliable operation over a long period of time.

[0024] Furthermore, as an optional implementation, the aforementioned second docking structure 5 can be a plurality of protrusions 51 uniformly arranged circumferentially along the bottom inner wall of the housing 1, near the edge of the opening. These protrusions 51 are integrally injection molded with the housing 1 to ensure maximum structural strength and assembly accuracy. Their number, for example, three or four, can be optimized while ensuring connection stability to facilitate quick alignment by the user.

[0025] The design of the second docking structure 5 aims to provide a macroscopic and robust structural connection, which is essentially a multi-point contact limiting and locking system. Its main function is to withstand the overturning torque and radial load transmitted to the drive device by the external functional device during the cooking process, especially when handling high-viscosity or uneven ingredients, ensuring that there is no shaking, misalignment or accidental separation between the two.

[0026] This mating structure, composed of multiple independent protrusions 51, offers excellent compatibility, enabling reliable engagement with various external functional devices. In one possible application, these protrusions 51 can mate with multiple L-shaped slots on the external functional device, forming a classic snap-fit ​​connection. During installation, the user simply aligns the L-shaped slot of the functional device with the protrusion 51 and inserts it axially. Then, by rotating it slightly clockwise or counterclockwise, the protrusion 51 slides into the horizontal section of the L-shaped slot, simultaneously achieving axial locking and circumferential limiting. The entire process is quick, intuitive, and provides clear tactile feedback.

[0027] It should be noted that the protrusion 51, as a general positioning and locking feature, can also effectively cooperate with other structures. For example, in some functional devices with higher requirements for quick insertion and removal, the mating structure can be designed as a vertical guide groove corresponding to the protrusion 51, with an elastic buckle or recess at the end of the groove. When the functional device is axially inserted into place, the protrusion 51 will pass over the buckle and embed into the recess, forming a press-type snap-fit ​​connection that can be fixed without rotation. Furthermore, for some low-torque, light-load applications, the mating structure on the external functional device can also be a wedge-shaped groove with a slight taper, achieving fixation through frictional self-locking between the protrusion 51 and the wedge-shaped groove. Therefore, those skilled in the art should understand that the protrusion 51, as a basic mechanical limiting structure, can be designed in various ways according to specific application requirements, and should not be limited to just one implementation method.

[0028] Example 2: Based on Embodiment 1, this embodiment provides a blender that uses the aforementioned drive device and is a possible specific application of the drive device in Embodiment 1.

[0029] Please see the appendix Figures 10 to 17 This blender mainly consists of a detachable functional unit and a drive unit. The drive unit is the modular power unit with a double-connection structure detailed in Embodiment 1. The functional unit is an independent module integrating transmission and working mechanisms, mainly including a connecting end cap 7 serving as a structural base, a drive shaft 8 passing through its center, and a mixing element 9 replaceably fixed to the lower end of the drive shaft 8. Depending on the specific cooking task, the mixing element 9 can be a whisk made of food-grade stainless steel (e.g., 304 stainless steel), a dough hook for kneading, or a mixing paddle for mixing, etc.

[0030] In this embodiment, the connecting end cover 7 of the functional device serves as a replaceable functional adapter, integrating corresponding structures that can match the two physical interfaces on the drive device, thereby achieving a dual-locking connection method. Specifically, the upper surface of the connecting end cover 7 has a third docking structure 10 that matches the first docking structure 4 of the drive device in size, shape, and function. This structure is mainly responsible for precise positioning and torque transmission. Simultaneously, on the upper periphery of the connecting end cover 7, a fourth docking structure 11 is also provided, which is assembled and fixed to the second docking structure 5 of the drive device. This structure is mainly responsible for providing structural rigidity and axial locking.

[0031] During actual assembly, the user holds the functional device, aligns its drive shaft 8 with and passes it through the first through hole 31 on the drive unit mounting plate 3, so that the polygonal or spline interface at the upper end of the drive shaft 8 initially engages with the power output interface 21 of the drive unit. During this process, the third docking structure 10 guides and positions the first docking structure 4, followed by alignment of the fourth docking structure 11 with the second docking structure 5. The user can simultaneously complete the engagement and locking of the two docking structures with a simple rotational motion. The entire process provides clear physical feedback, is convenient to operate, and is less prone to errors.

[0032] To achieve the aforementioned dual cooperation, the drive device in this embodiment preferably possesses all the technical features described in Embodiment 1, namely, the first docking structure 4 includes a first annular groove 41, an axial limiting groove 43, and a second annular groove 44, while the second docking structure 5 consists of multiple protrusions 51. Correspondingly, the connecting end cap 7 of the mixer functional device is also designed with a strictly corresponding matching structure. Its third docking structure 10 includes a first annular protrusion 101 arranged around the axis of the drive shaft 8. The diameter, height, and tolerance of this protrusion are precisely calculated to ensure that it can be smoothly embedded into the first annular groove 41 of the drive device with a very small gap, achieving primary radial positioning. Around the periphery of the first annular protrusion 101, a second annular protrusion 102 with a larger diameter is also coaxially arranged. This protrusion is used to embed into the second annular groove 44 of the drive device, forming secondary radial positioning. This double-ring concentric positioning structure greatly increases the stability of the connection and effectively resists lateral shaking caused by uneven force during stirring. Within the annular region between the first annular protrusion 101 and the second annular protrusion 102, there are multiple first limiting ribs 103 integrally formed, which are completely consistent with the axial limiting grooves 43 of the drive device in terms of quantity, angle and shape. The meshing of the two constitutes the core of torque transmission, ensuring that the motor power is transmitted to the drive shaft 8 without loss.

[0033] Furthermore, the fourth docking structure 11 in this embodiment, i.e., the implementation of structural locking, is specifically manifested as multiple L-shaped grooves 111 evenly spaced at equal angles along the outer peripheral wall of the second annular protrusion 102. Each L-shaped groove 111 precisely corresponds to a protrusion 51 on the drive device. In the final step of installation, the user rotates the functional device clockwise (or counterclockwise), and the protrusion 51 on the drive device slides along the guide wall of the L-shaped groove 111 and finally engages with the end of the horizontal section of the L-shaped groove. To prevent loosening due to vibration, a small indentation or elastic protrusion can also be designed at the end of the horizontal section to provide additional locking force. This bayonet-type connection method is not only intuitive to operate and securely locked, but also tightly fixes the functional device as a whole to the housing of the drive device, forming a robust whole.

[0034] Example 3: Based on Embodiment 1, this embodiment provides a high-speed blender that uses the aforementioned drive device, representing another possible specific application of the drive device from Embodiment 1.

[0035] Please refer to the accompanying drawings. This high-speed blender includes a container 12 and a top cover 13. A rotating part 14 is located at the center of the bottom surface of the container 12. This rotating part 14 can be a fixed, upward-extending pin-like structure, serving as the central fulcrum and positioning reference for the rotation of the blade 15. The blade 15 is rotatably mounted on the fixed rotating part 14 via a bearing seat at its bottom. The top cover 13 is used to close the opening of the container 12. The drive unit is mounted on the top cover 13 as a separate module.

[0036] Specifically, the upper surface of the top cover 13 is provided with a mounting groove 16, which is a pre-set recess. The drive device described in Embodiment 1 is entirely installed and fixed within this mounting groove 16. The inner wall of the mounting groove 16 is integrally formed with a fifth docking structure 17 that matches the first docking structure 4 of the drive device. The upper end of the cutter 15 extends into a transmission end 151, which passes through the inner cavity of the container 12, then through the third through hole 161 opened in the center of the top cover 13, and finally connects to the power output interface 21 of the drive device mounted on the top cover 13.

[0037] In a preferred embodiment, the driving device in this embodiment includes the first annular groove 41 and the axial limiting groove 43 described in Embodiment 1. Correspondingly, the fifth mating structure 17 within the mounting groove 16 of the top cover 13 also has a corresponding mating structure. Specifically, the fifth mating structure 17 includes a third annular protrusion 171 arranged around the third through hole 161 on the inner wall of the mounting groove 16, the shape of which matches the first annular groove 41 of the driving device. Simultaneously, along the outer periphery of the third annular protrusion 171, a plurality of second limiting ribs 172 corresponding to the axial limiting groove 43 of the driving device are uniformly arranged. Through the cooperation of these structures, it is ensured that the driving device can be accurately and securely fixed to the top cover 13.

[0038] It is important to note that in this application configuration of the blender, although the second docking structure 5 (i.e., multiple protrusions 51) installed on the bottom edge of the drive unit housing 1 objectively exists as a standardized interface for the drive unit, no matching structure is designed on the top cover 13. Therefore, it is a spare, unactivated design in this case. This is based on two considerations. First, structurally speaking, the main fixing and anti-rotation functions between the drive unit and the top cover 13 are fully assumed by the more precise engagement between the first docking structure 4 and the fifth docking structure 17. Second, from the perspective of human-computer interaction, users typically use both hands in a coordinated manner when using this type of top-mounted blender. One hand firmly holds the upper part of the drive unit for starting and control, while the other hand naturally supports the container 12 below to sense its stability. This coordinated two-handed operation forms a stable closed-loop force system, which is sufficient to easily counteract the reverse torque generated during motor startup and high-speed operation, ensuring absolute stability during operation. Therefore, the additional mechanical locking function provided by the second docking structure 5 is not necessary in this application scenario, and it exists as a reserved feature for the universality of the drive device, so as to facilitate the replacement of other functional devices.

[0039] Furthermore, when the motor drives the cutter to rotate at high speed, the resulting reaction torque is applied to the top cover 13, which is fixed to the motor. Without an effective limiting structure, the top cover 13 itself will be driven to rotate by this force. To fundamentally prevent the top cover 13 from being rotated, the opening of the container 12 in this embodiment is designed to be non-circular, for example, a regular polygon with multiple concave arcs. Correspondingly, the bottom of the top cover 13 also has an interlocking portion 131 that perfectly matches the shape of the regular polygonal opening. When the top cover is closed, this non-circular mechanical interlocking structure provides circumferential locking, ensuring that the top cover 13 and the container 12 always maintain a firm relative stationary state.

[0040] Furthermore, as an optional implementation, the blade 15 can adopt a multi-layer composite structure. Specifically, the blade 15 includes a connecting sleeve 152 connected to the rotating part 14. Above the connecting sleeve 152, multiple connecting blocks 153 are stacked and fitted together using a spline or polygonal fit, with the transmission end 151 fixed to the upper end of the topmost connecting block 153. A first blade 154 is installed between the bottommost connecting sleeve 152 and the first connecting block 153, and a second blade 155 is installed between any two adjacent connecting blocks 153. This multi-layer blade structure can cut and pulverize the food in the container from all angles without dead angles, greatly improving the cell wall breaking efficiency and fineness.

[0041] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
