Description

Technical Field

[0001] This invention relates to the field of vibration damping devices for food processing equipment, and particularly to a food processor. Background Technology

[0002] In modern kitchen equipment, manual food processors are a common food preparation tool widely used in homes and small restaurants. Existing food processors are generally similar in structure, mainly consisting of a container, a drive assembly, a fixed blade holder, and blades mounted on the blade holder. In actual operation, the user drives a drive mechanism, which rotates the blade holder around a fixed axis, causing the blades mounted on the holder to cut the food placed in the container.

[0003] However, this traditional manual food processor has revealed numerous problems in actual use. In the initial cutting stage, because the blade holder is fixed, the blades can only rotate within a single plane. At this time, a large amount of uncrushed food material concentrates on the blade surface. This causes the blades to overcome significant resistance during cutting, often requiring users to expend considerable physical effort to turn the handle. In some cases, some users even find it difficult to turn the handle due to the excessive resistance, causing the food processor to malfunction. Utility Model Content

[0004] In existing technologies, some products increase the number of blades, hoping to distribute resistance by having multiple blades work simultaneously. However, the fixed structure of the blade holder remains unchanged. As food accumulates, the cutting resistance is still difficult to distribute effectively, and the cutting efficiency continues to decline, failing to balance labor-saving and practicality. To address the above technical problems, the specific technical solution of this utility model is as follows:

[0005] A food processor, comprising:

[0006] Container, lid, drive assembly, tool holder, and blade;

[0007] The container has an opening on its top surface, the cover is disposed at the opening on the top surface of the container, and the drive assembly is disposed within the hollow cavity of the cover.

[0008] A fixing post is provided on the inner bottom surface of the container. One end of the fixing post away from the inner bottom surface of the container is a guide slope. An inner groove is provided at the bottom of the tool holder. The bottom surface of the inner groove is an inclined slope that matches the slope of the guide slope. The tool holder is sleeved on the outer circumference of the fixing post through the inner groove.

[0009] When the drive assembly drives the tool holder to rotate around the fixed column, the tool holder generates axial displacement.

[0010] Furthermore, the top of the tool holder is provided with a snap-fit ​​protrusion, the output shaft of the drive assembly passes through the cover and extends into the container, and the end of the output shaft facing the container is provided with a snap-fit ​​groove that matches the shape of the snap-fit ​​protrusion. The snap-fit ​​protrusion is disposed in the snap-fit ​​groove. When the output shaft rotates, it drives the snap-fit ​​protrusion to rotate, which in turn drives the tool holder to rotate.

[0011] Furthermore, the tool holder is characterized in that a snap-fit ​​groove is provided on the top of the tool holder, the output shaft of the drive assembly passes through the cover and extends into the container, and a snap-fit ​​protrusion adapted to the shape of the snap-fit ​​groove is provided on the end of the output shaft facing the container. The snap-fit ​​protrusion is disposed in the snap-fit ​​groove, and when the output shaft rotates, it drives the snap-fit ​​groove to rotate, which in turn drives the tool holder to rotate.

[0012] Furthermore, the locking protrusion generates axial displacement within the locking groove as the tool holder moves axially, and the depth of the locking groove is greater than the axial displacement distance of the locking protrusion.

[0013] The cross-sections of the snap-fit ​​protrusion and the snap-fit ​​groove are polygonal.

[0014] Furthermore, the drive assembly includes a hand lever, the extension direction of which is perpendicular to the output shaft of the drive assembly, and the side of the hand lever near the output shaft is arranged around the output shaft; when the hand lever is pulled away from the side of the output shaft, the hand lever drives the output shaft to rotate, which in turn drives the locking protrusion to rotate.

[0015] Furthermore, the driving component includes a drive motor, which drives the output shaft to rotate, further causing the locking protrusion to rotate.

[0016] Furthermore, the inner wall of the inner groove is provided with two or more protrusions of different heights at intervals, and the plane on which the tops of the multiple protrusions are located simultaneously is the inclined plane;

[0017] or,

[0018] Two or more protruding points are provided at intervals on the inclined surface of the inner groove of the tool holder.

[0019] Furthermore, two or more protruding points are spaced apart on the guide slope of the fixed column, and the plane on which the tops of the multiple protruding points are located simultaneously is the guide slope.

[0020] Furthermore, at least two sets of cross-arranged blades are detachably mounted on the blade holder, with the blades and the blade holder arranged at an angle of 15° to 75°.

[0021] Furthermore, at least one scraper is fixed near the bottom of the container on the blade holder, and one end of the scraper opposite to the blade holder extends to the inner wall of the container.

[0022] Furthermore, the angle between the guide slope of the fixed column and the fixed column is 15° to 45°.

[0023] This invention features a fixed post on the bottom surface of the container, whose guide slope precisely matches the inclined surface of the blade holder's inner groove. When the drive assembly rotates the blade holder, it not only revolves around the fixed post but also generates controllable axial displacement along the inclined direction. This allows the blade to dynamically adjust its position during cutting, maintaining the optimal contact angle with the food, preventing localized accumulation, and achieving uniform resistance distribution, significantly improving cutting efficiency. Simultaneously, the axial movement of the blade holder expands the cutting range, reduces unprocessed areas, and ensures the food is thoroughly cut and mixed. Users no longer need to pre-cut the food, greatly simplifying the pre-processing steps and achieving a dual improvement in labor-saving and practicality. Attached Figure Description

While specific embodiments of the present invention have been shown, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] It should be noted that certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that different terms may be used to refer to the same component. This specification and claims do not distinguish components based on differences in terminology, but rather on differences in function. The terms "comprising" or "including" used throughout the specification and claims are open-ended and should be interpreted as "comprising but not limited to." The following descriptions are preferred embodiments of the present invention; however, these descriptions are intended to illustrate the general principles of the specification and are not intended to limit the scope of the present invention. The scope of protection of this invention shall be determined by the appended claims.

[0034] refer to Figure 1a As shown, it illustrates a food processor of the present invention, comprising:

[0035] Container 10, cover 20, drive assembly 30, knife holder 40 and blade 50;

[0036] The container 10 has an opening on its top surface, and the cover 20 is disposed at the opening on the top surface of the container 10. The drive assembly 30 is disposed in the hollow cavity of the cover 20. A fixing post 11 is disposed on the inner bottom surface of the container 10, and one end of the fixing post 11 away from the inner bottom surface of the container 10 is a guide slope. The bottom of the tool holder 40 is provided with an inner groove 42, and the bottom surface of the inner groove 42 is an inclined slope that matches the slope of the guide slope. The tool holder 40 is sleeved on the outer circumferential surface of the fixing post 11 through the inner groove 42. When the drive assembly 30 drives the tool holder 40 to rotate around the fixing post 11, the tool holder 40 generates axial displacement.

[0037] Specifically, the container 10 serves as the main space for food processing. The top surface of the container 10 has an opening, and the lid 20 precisely covers the opening of the container 10, forming a sealed working environment. The drive assembly 30 is disposed within the hollow cavity of the lid 20, which protects the internal mechanical structure of the drive assembly 30 from food contamination and ensures a compact power transmission. A fixed post 11 with a specific slope is fixed at the center of the inner bottom surface of the container 10. The bottom of the blade holder 40 is provided with an inner groove 42 that precisely matches the slope of the fixed post 11. The blade holder 40 is fitted onto the outer circumferential surface of the fixed post 11 through the inner groove 42. When the drive assembly 30 drives the blade holder 40 to rotate around the fixed post 11, the cooperation between the inner groove 42 of the blade holder 40 and the slope of the fixed post 11 causes the blade holder 40 to generate axial displacement while rotating circumferentially. This composite motion trajectory enables the blade 50 to achieve multi-dimensional and efficient cutting of food, significantly reducing cutting resistance and improving the uniformity of food processing. At the same time, it effectively disperses the resistance when cutting food, significantly reducing the force required by the user during operation and greatly improving the cutting efficiency of the food processor.

[0038] In one specific embodiment, the top of the blade holder 40 is provided with a locking protrusion 41. The output shaft of the drive assembly passes through the cover and extends into the container. The end of the output shaft facing the container has a locking groove that matches the shape of the locking protrusion. The locking protrusion 41 is disposed in the locking groove 31. When the output shaft rotates, it drives the locking protrusion 41 to rotate, further driving the blade holder 40 to rotate. In the food processor, the top of the blade holder 40 is provided with the locking protrusion 41, which forms a precise fit with the locking groove 31 at the end of the output shaft of the drive assembly 30. The locking protrusion 41 is embedded in the locking groove 31, and the two are circumferentially fixed through the complementary nature of their geometric shapes. When the output shaft of the drive assembly 30 rotates under the action of a power source, the inner wall of the locking groove 31 applies torque through its contact surface with the locking protrusion 41, driving the locking protrusion 41 of the blade holder 40 to rotate synchronously. Because an effective motion transmission path is formed between the tool holder 40 and the output shaft through a snap-fit ​​structure, the rotational motion of the output shaft is precisely converted into the circumferential motion of the tool holder 40 around the fixed column 11. This snap-fit ​​transmission design achieves efficient torque transmission between the drive assembly 30 and the tool holder 40 through shape matching, and also facilitates the disassembly and maintenance of the tool holder 40.

[0039] In one specific embodiment, the top of the tool holder is provided with a snap-fit ​​groove. The output shaft of the drive assembly passes through the cover and extends into the container. The end of the output shaft facing the container has a snap-fit ​​protrusion that matches the shape of the snap-fit ​​groove. The snap-fit ​​protrusion is disposed in the snap-fit ​​groove. When the output shaft rotates, it drives the snap-fit ​​groove to rotate, further driving the tool holder to rotate. The drive structure of the tool holder includes the tool holder body with the snap-fit ​​groove on its top and the drive assembly with the output shaft. The output shaft passes vertically through the central through-hole of the cover and extends into the working area inside the container. One end face of the output shaft located inside the container has an integrally formed snap-fit ​​protrusion whose geometric shape is complementary to the snap-fit ​​groove on the top of the tool holder. The snap-fit ​​protrusion forms a detachable engagement connection with the snap-fit ​​groove by axial insertion. When the drive assembly is started, the output shaft generates circumferential rotation under the action of the power source. The snap-fit ​​protrusion drives the snap-fit ​​groove on the top of the tool holder to rotate synchronously through the friction of the contact surface, thereby realizing the rotational movement of the tool holder around the axis of the output shaft. This design significantly improves the power transmission efficiency and enables quick replacement and maintenance of the tool holder through the modular snap-fit ​​structure.

[0040] In one specific embodiment, the engaging protrusion 41 undergoes axial displacement within the engaging groove 31 as the blade holder 40 moves axially. The depth of the engaging groove 31 is greater than the axial displacement distance of the engaging protrusion 41. In the mating structure of the blade holder 40 and the drive assembly 30 of the food processor, the engaging protrusion 41 at the top of the blade holder 40 synchronously undergoes axial displacement within the engaging groove 31 of the output shaft of the drive assembly 30 as the blade holder 40 moves axially. The depth of the engaging groove 31 must be greater than the displacement distance of the engaging protrusion 41 when the blade holder 40 has its maximum axial displacement, thereby preventing the engaging protrusion 41 from disengaging from the engaging groove 31 during the axial movement of the blade holder 40.

[0041] In one specific embodiment, the cross-sections of the snap-fit ​​protrusion 41 and the snap-fit ​​groove 31 are polygonal. The polygonal design of both the snap-fit ​​protrusion 41 and the snap-fit ​​groove 31 not only increases the contact area between them and improves torque transmission efficiency, but also enhances the connection stability between the tool holder 40 and the drive assembly 30 through the geometric constraints of the polygon, ensuring that the entire transmission system maintains a stable and reliable engagement state even when transmitting large torques.

[0042] This invention does not limit the cross-sectional shape of the snap-fit ​​protrusion 41 and the snap-fit ​​groove, and can be customized according to actual needs.

[0043] In one specific embodiment, the drive assembly 30 includes a hand lever 32, the direction of which is perpendicular to the output shaft of the drive assembly 30, and the hand lever 32 is arranged around the output shaft on the side closest to the output shaft; when the hand lever 32 is pulled away from the output shaft, the hand lever 32 drives the output shaft to rotate, which in turn drives the locking protrusion 41 to rotate. Figure 1b As shown, the lever 32 is configured perpendicular to the output shaft of the drive assembly 30, and the side of the lever 32 closest to the output shaft is arranged around the output shaft. When the operator applies external force to pull the lever 32 away from the output shaft, the lever 32, through its specific structure surrounding the output shaft, drives the output shaft to rotate. This rotation is further converted into a circumferential rotation of the blade holder 40 around the fixed post 11 through the precise engagement of the locking groove 31 at the end of the output shaft and the locking protrusion 41 on the top of the blade holder 40, thereby driving the blade 50 to cut and process the food. The drive design of the lever 32 fully optimizes the mechanical efficiency of manual operation, allowing the user to easily apply driving force in the most ergonomic posture, while ensuring efficient transmission between the drive assembly 30 and the blade holder 40.

[0044] In one specific embodiment, the surface of the pull rod 32 is further provided with anti-slip texture or a soft covering layer to enhance operating comfort and safety.

[0045] In one specific embodiment, the drive assembly 30 includes a drive motor that drives the output shaft to rotate, further rotating the locking protrusion 41. The drive motor is integrated into or externally mounted within the drive assembly 30. The drive motor is powered by a reduction gear set connected to the transmission shaft of the blade holder 40. When the electric drive mode is activated, the rotational torque generated by the motor is adjusted by the reduction gear set to drive the blade holder 40 to achieve stable rotation at the optimal speed and torque. The drive motor is equipped with a control circuit board, enabling multi-speed adjustment and overload protection; it automatically cuts off the power when excessive resistance is detected in the blade 50. The drive motor can be powered by a built-in rechargeable lithium battery or by connecting to an external power source via a power adapter. The drive assembly 30 can also retain a manual operation mode to ensure normal operation even when power is insufficient. This significantly improves the processing efficiency of the food processor, and the cutting effect can be further optimized through precise speed control.

[0046] In one specific implementation, such as Figure 3a and Figure 3bAs shown, the inner wall of the inner groove 42 is provided with multiple protrusions 43 of different heights at intervals. The plane on which the tops of the multiple protrusions 43 are located is the inclined plane. The tops of the multiple protrusions 43 together form an inclined plane that is perfectly matched with the guide inclined plane of the fixed column 11. When the blade holder 40 rotates around the fixed column 11 under the action of the drive assembly 30, the structure of the protrusions 43 on the side wall of the inner groove 42 not only realizes the axial displacement of the blade holder 40 through the cooperation of the inclined plane and the inclined plane of the fixed column 11, but also forms a dynamic guiding effect through the height difference of the protrusions 43 during the displacement process, further enhancing the stability and controllability of the movement of the blade holder 40, and ensuring that the blade 50 always maintains the best cutting angle and force when processing food.

[0047] In one specific embodiment, the bottom surface of the inner groove 42 is an inclined plane that matches the slope of the guide slope. Multiple raised points 43 of equal height are spaced apart on the bottom surface of the groove, and the plane on which the tops of these raised points 43 are located is an inclined plane. The bottom surface of the inner groove 42 is designed as an inclined plane that precisely matches the guide slope of the fixed column 11, ensuring that the blade holder 40 can generate stable axial displacement during rotation. Multiple evenly distributed raised points 43 of equal height are provided on the bottom surface of the groove. The tops of these raised points 43 together form a continuous inclined plane. The cooperation between this plane and the inclined plane of the fixed column 11 not only achieves precise guidance for the axial movement of the blade holder 40, but also increases frictional resistance through the multi-point contact between the raised points 43 and the surface of the fixed column 11, thereby increasing the rotational torque transmitted from the drive assembly 30 to the blade holder 40. This allows the blade holder 40 to obtain greater cutting force when cutting food, significantly improving food processing efficiency.

[0048] This invention does not limit the number of the protruding points 43, and can be customized according to actual needs.

[0049] In one specific embodiment, two or more protruding points are spaced apart on the guide slope of the fixed column, and the plane on which the tops of the multiple protruding points simultaneously lie is the guide slope. On the guide slope of the fixed column, three or more hemispherical protruding points are evenly distributed at intervals along the circumference. After precision machining, the highest points of the protruding points collectively form a reference plane at a preset angle to the axis of the fixed column. This reference plane perfectly coincides geometrically with the theoretically designed plane of the guide slope, forming a composite friction interface with a micro-undulating structure. This not only effectively increases the contact area through the micro-protrusion structure, but also generates controllable micro-elastic deformation during dynamic engagement, maintaining a stable coefficient of friction under different axial pressures, significantly improving the stability and repeatability accuracy of the guiding positioning.

[0050] In one specific embodiment, at least two sets of cross-arranged blades 50 are detachably mounted on the blade holder 40, with the blades 50 forming an angle of 15° to 75° with the blade holder 40. The blades 50 are fixed to the blade holder 40 via quick-release clips or threaded connections, allowing users to replace or clean them according to the characteristics of the ingredients. The angle between the blades 50 and the blade holder 40 is 15° to 75°, for example, it can be one or any two of the following values: 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, and 75°, preferably 30° to 60°. The inclined arrangement of the blades 50 allows them to create a progressive cutting action during rotary cutting, effectively dispersing cutting resistance. The cross-arrangement of the blades 50 forms a three-dimensional cutting network in space, effectively dispersing cutting resistance when the blade holder 40 undergoes combined rotary and axial movements. The blade 50 is made of food-grade stainless steel, and its cutting edge undergoes a special hardening treatment to ensure sharpness while extending its service life. By optimizing the layout angle and detachable structure of the blade 50, it not only meets the diverse food processing needs but also facilitates user maintenance, greatly improving the practicality and durability of the food processor.

[0051] In one specific embodiment, at least one scraper 60 is fixedly mounted on the blade holder 40 near the bottom of the container 10, with one end of the scraper 60 extending away from the blade holder 40 to the inner wall of the container 10. The blade holder 40 is fixedly mounted with at least one scraper 60 near the bottom of the container 10, one end of the scraper 60 is securely connected to the blade holder 40, and the other end extends to touch the inner wall of the container 10. When the blade holder 40 rotates around the fixed column 11 under the action of the drive assembly 30, the scraper 60 rotates synchronously with the blade holder 40. Its end extending to the inner wall of the container 10 can effectively scrape off food residue adhering to the inner wall of the container 10, thereby ensuring that the food is fully cut and mixed, avoiding food waste, and further improving the overall working efficiency of the food processor.

[0052] In one specific embodiment, the scraper 60 is made of a flexible material, and the end of the scraper 60 elastically contacts the inner wall of the container 10. The scraper 60 of the food processor is made of a flexible material, and the end of the scraper 60 elastically contacts the inner wall of the container 10. When the blade holder 40 rotates the scraper 60, under the combined action of centrifugal force and the reaction force of the food, the end of the flexible scraper 60 tightly adheres to the surface of the inner wall of the container 10, resulting in elastic deformation. This ensures an efficient seal between the scraper 60 and the inner wall of the container 10, effectively preventing food from leaking through the gap between the scraper 60 and the inner wall of the container 10. Furthermore, the elastic buffering effect of the flexible material avoids rigid collisions between the scraper 60 and the inner wall of the container 10, extending the service life of the scraper 60. Simultaneously, it ensures the wide applicability of the scraper 60 to the inner walls of containers 10 of different sizes and shapes.

[0053] In one specific implementation, such as Figure 3a and Figure 3b As shown, the angle between the guide slope of the fixed column and the fixed column is 15° to 45°, for example, it can be 15°, 18°, 20°, 23°, 25°, 28°, 30°, 33°, 35°, 38°, 40°, 43°, 45°, preferably 25° to 30°. The slope of the guide slope of the fixed column 11 and its axis is precisely controlled between 15° and 45°; this ensures that when the tool holder 40 rotates around the fixed column 11, the inner groove 42 and the guide slope of the fixed column 11 remain within the guide slope. The inclined plane produces an ideal axial displacement, which not only ensures the stability of the blade holder 40's movement but also allows for precise adjustment of the cutting force on the food by controlling the displacement speed. The minimum inclination of 15° avoids sudden changes in cutting resistance caused by excessive displacement during the initial rotation of the blade holder 40, while the maximum inclination of 45° ensures that the blade holder 40 can maintain sufficient axial displacement to achieve deep cutting of the food even when it reaches its maximum rotation speed, thereby significantly improving the overall working performance of the food processor.

[0054] In one specific embodiment, the axial displacement distance of the blade holder 4030 is 15-35mm. For example, it can be one or any two of the following values: 15mm, 18mm, 20mm, 23mm, 25mm, 28mm, 30mm, 33mm, and 35mm. The axial displacement distance generated when the blade holder 40 rotates around the fixed column 11 is strictly limited to between 15mm and 35mm. This ensures that when cutting food of different hardness, the blade holder 40 can achieve deep cuts with sufficient displacement, while avoiding the risk of collision between the blade holder 40 and the inner wall of the container 10 due to excessive displacement. The minimum displacement of 15mm ensures that the blade holder 40 can still maintain effective cutting when processing soft food, while the maximum displacement of 35mm allows the blade holder 40 to fully exert its cutting force when processing hard food. This not only improves the efficiency of food processing but also significantly enhances the safety and reliability of the food processor.

[0055] Example

[0056] A manually driven food processor features a blade holder with a hexagonal hexagonal cross-section at the top, precisely engaging with a hexagonal groove at the end of the output shaft. The inner wall of the blade holder's inner groove has staggered triangular protrusions, all forming an inclined plane with a 30° angle that matches the guide slope of the fixed column. As the blade holder rotates around the fixed column, the engagement between the inner groove and the inclined surface creates a 30mm axial displacement, allowing the blades to cut deeply into the food. Two symmetrically distributed flexible silicone scrapers are fixedly mounted near the bottom of the container. The scraper tips extend to the inner wall of the container and maintain elastic contact, ensuring the scrapers closely adhere to the container's sidewalls of varying inner diameters during rotation, effectively removing any adhering substances. The drive assembly includes a lever, which is perpendicular to the output shaft and is positioned around the output shaft on the side closest to it. When the lever is pulled away from the output shaft, it causes the output shaft to rotate, which in turn causes the locking protrusion to rotate, driving the blade holder to rotate around the fixed post, thereby achieving the cutting and processing of food ingredients.

[0057] This invention significantly improves the cutting efficiency, ease of operation, and convenience of use of a food processor through multi-dimensional structural innovation and material optimization. It employs a beveled engagement mechanism, where the guide bevel on the top surface of the cylinder slides into a precisely matched inclined inner groove inside the blade holder. The blade holder rotates while undergoing axial displacement, causing the blades to form a wave-shaped cutting trajectory, dispersing initial cutting resistance. The intersecting blade groups construct a three-dimensional cutting network, which, combined with the serrated protrusions at the bottom of the container, forms a food fixing and guiding system, effectively preventing food slippage and improving cutting uniformity.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
