Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and more specifically, to a food processor. Background Technology

[0002] Currently, in the design of household electric meat grinders, existing technical solutions typically involve installing a fixed shaft at the bottom of the grinding cup to support the rotation of the blade assembly. The lower end of the blade assembly is fitted onto the fixed shaft, while the upper end is connected to the motor. The motor's power is directly transmitted to the blade assembly, enabling it to perform the task of grinding the food.

[0003] However, in existing technologies, the mating length between the fixed shaft and the cutter assembly is relatively long, which means that the contact area between them is large. When the motor drives the cutter assembly to rotate, the large contact area leads to significant frictional resistance. This resistance not only consumes the motor's output power, reducing the meat grinder's working efficiency and shortening its service life, but also generates high noise at high speeds, affecting the user experience. If the mating length between the fixed shaft and the cutter assembly is shortened to reduce friction, the cutter assembly may loosen or even fall off due to centrifugal force during high-speed rotation. Utility Model Content

[0006] Furthermore, the connecting structure is a first connecting shaft, the central axis of the first connecting shaft is coaxially arranged with the rotation axis of the tool assembly, and the first gap is distributed along the circumferential and / or axial direction of the first connecting shaft.

[0007] Furthermore, the food processor also includes a second connecting shaft, the first end of which is disposed on the inner bottom surface of the food processor cup, the first end of which has a first mounting hole, and the second end of which extends into and is connected to the first mounting hole; wherein, the first gap is disposed closer to the first end of the connecting structure relative to the second gap.

[0008] Furthermore, the tool assembly includes: a tool shaft having a second mounting hole; and a cutting blade disposed on the outer circumferential surface of the tool shaft; wherein at least a portion of the first connecting shaft extends into the second mounting hole to achieve a nested fit between the tool assembly and the connecting structure.

[0009] Furthermore, the first connecting shaft includes a first shaft segment and a second shaft segment connected to each other. The outer diameter D1 of the first shaft segment is greater than the outer diameter D2 of the second shaft segment. A second gap is formed between the outer surface of the first shaft segment and the wall of the second mounting hole, and a first gap is formed between the outer surface of the second shaft segment and the wall of the second mounting hole. The end of the second shaft segment away from the first shaft segment forms the first end of the first connecting shaft.

[0010] Furthermore, the difference between the outer diameter D1 of the first shaft segment and the outer diameter D2 of the second shaft segment is greater than or equal to 0.1 mm.

[0011] Furthermore, the length L1 of the first shaft segment and the total length L of the first connecting shaft satisfy the condition: 0.5L < L1.

[0012] Furthermore, along the direction from the first shaft segment to the second shaft segment, the outer diameter of the second shaft segment gradually decreases; or, the outer diameter of the second shaft segment first decreases and then increases.

[0013] Furthermore, the end of the first shaft segment away from the second shaft segment is provided with a rounded corner.

[0014] Furthermore, a groove is provided on the outer surface of the first connecting shaft, and a first gap is formed between the groove and the wall of the second mounting hole; wherein, the groove extends circumferentially along the first connecting shaft; and / or, the groove is an arc-shaped groove or an annular groove.

[0015] Furthermore, there may be one groove; or there may be multiple grooves, which are spaced apart along the axial direction of the first connecting shaft.

[0016] Furthermore, a convex hull is provided on the second shaft segment, and there is one convex hull; or, there are multiple convex hulls, which are spaced apart along the circumferential and / or axial direction of the second shaft segment.

[0017] Furthermore, the food processor is a meat grinder.

[0018] The present invention relates to a food processor comprising a body, a food processor cup, and a blade assembly. The body includes a cover and a drive device housed within the cover. The food processor cup is detachably connected to the cover, and a connecting structure is provided on the inner bottom surface of the food processor cup. The drive device is driven to the first end of the blade assembly to drive the blade assembly to rotate. The second end of the blade assembly and the connecting structure are nested together. A first gap exists between a portion of the connecting structure and the second end of the blade assembly, and a second gap exists between a portion of the connecting structure and the second end of the blade assembly. The first gap is larger than the second gap. Thus, given the fit length between the connecting structure and the blade assembly, the connecting structure and the blade assembly do not contact each other at the first gap, or the contact area at the first gap is small. During the rotation of the blade assembly, the aforementioned arrangement of the first and second gaps reduces the contact area between the connecting structure and the blade assembly, especially in areas where significant friction occurs during high-speed rotation. This reduces unnecessary friction and solves the problem in the prior art where the friction between the fixed shaft and the blade assembly of the food processor is too high, affecting the lifespan of the food processor and the user experience. This reduces noise during operation, extends the lifespan of the food processor, and improves the user experience. Meanwhile, the clearance fit between the connecting structure and the cutting tool assembly ensures a stable connection between the cutting tool assembly and the connecting structure, preventing the cutting tool assembly from shaking or falling off due to an excessively loose fit, thus enhancing operational safety and ensuring the effectiveness and uniformity of the meat grinding process.

[0034] In order to solve the problem that the friction between the fixed shaft and the blade assembly of the food processor is too large in the prior art, which affects the service life of the food processor and the user experience, this application provides a food processor.

[0035] Example 1

[0036] like Figures 1 to 5 As shown, the food processor includes a body 10, a food processor cup 20, and a blade assembly 40. The body 10 includes a cover 11 and a drive unit 12 disposed within the cover 11. The food processor cup 20 is detachably connected to the cover 11, and a connecting structure 30 is provided on the inner bottom surface of the food processor cup 20. The drive unit 12 is driven to rotate the blade assembly 40 by connecting the first end of the blade assembly 40. The second end of the blade assembly 40 and the connecting structure 30 are nested together, with a first gap between a portion of the connecting structure 30 and the second end of the blade assembly 40, and a second gap between a portion of the connecting structure 30 and the second end of the blade assembly 40, the first gap being larger than the second gap.

[0037] By applying the technical solution of this embodiment, under the premise of the fit length between the connecting structure 30 and the blade assembly 40, the connecting structure 30 and the blade assembly 40 do not contact each other at the first gap or the contact area at the first gap is small. During the rotation of the blade assembly 40, the above-mentioned setting of the first gap and the second gap reduces the contact area between the connecting structure 30 and the blade assembly 40, especially for parts that generate greater friction during high-speed rotation, thereby reducing unnecessary friction. This solves the problem in the prior art where the friction between the fixed shaft and the blade assembly of the food processor is too large, affecting the service life of the food processor and the user experience. This reduces the noise during the operation of the food processor, extends its service life, and improves the user experience. At the same time, the gap fit between the connecting structure 30 and the blade assembly 40 ensures a stable connection between the blade assembly 40 and the connecting structure 30, preventing the blade assembly 40 from shaking or falling off due to an excessively loose fit, enhancing operational safety, and also ensuring the effectiveness and uniformity of the meat grinding process.

[0038] Optionally, the connecting structure 30 is a first connecting shaft, with its central axis coaxial with the rotation axis of the tool assembly 40, and the first gap distributed along the circumferential and / or axial direction of the first connecting shaft. This arrangement of the first gap reduces the direct contact area between the tool assembly 40 and the first connecting shaft during high-speed rotation, thereby reducing friction and noise generated during rotation. Furthermore, this arrangement allows for greater flexibility in the placement of the first gap to meet different usage requirements and working conditions, thus improving the processing flexibility of the operator.

[0039] In this embodiment, the connecting structure 30 is a first connecting shaft, whose central axis is coaxial with the rotation axis of the blade assembly 40, and the first gap is distributed circumferentially along the first connecting shaft. This coaxial alignment of the central axis of the first connecting shaft with the rotation axis of the blade assembly ensures precise transmission of driving force, avoids additional vibration and energy loss caused by axis misalignment, and improves power transmission efficiency. This results in smoother rotation of the blade assembly 40, enhancing the consistency and efficiency of the meat grinding effect. Simultaneously, this design simplifies the structure of the connecting structure 30, making it easier to manufacture and implement, thus reducing the processing cost and difficulty of the food processor.

[0040] In other embodiments not shown in the accompanying drawings, the first gap is distributed along the axial direction of the first connecting shaft.

[0041] In other embodiments not shown in the accompanying drawings, the first gap is distributed along the circumferential and axial directions of the first connecting shaft, i.e., the first gap is spirally coiled on the first connecting shaft.

[0042] like Figure 4As shown, the food processor also includes a second connecting shaft 50. The first end of the second connecting shaft 50 is disposed on the inner bottom surface of the food processor cup 20. The first end of the first connecting shaft has a first mounting hole 31. The second end of the second connecting shaft 50 extends into the first mounting hole 31 and is connected to the first mounting hole 31. The first gap is set closer to the first end of the connecting structure 30 relative to the second gap. In this way, by extending the second end of the second connecting shaft 50 into the first mounting hole 31 provided at the first end of the first connecting shaft, a stable connection is formed, ensuring that power is accurately transmitted from the drive device 12 of the body 10 to the blade assembly 40. At the same time, the first gap being set closer to the first end of the connecting structure relative to the second gap helps to absorb vibration in the initial stage of power transmission, reducing noise and wear caused by the instantaneous impact force during startup.

[0043] In this embodiment, during the rotation of the tool assembly 40, the differentiated design of the first gap and the second gap ensures that the first gap near the first end (i.e., the power input end), due to its size setting, can significantly reduce the contact area between the tool assembly and the connecting structure, thereby reducing frictional resistance, reducing energy consumption, and improving overall efficiency. Simultaneously, the nested connection between the second connecting shaft 50 and the first connecting shaft, as well as the reasonable distribution of the first and second gaps, ensure the structural stability of the tool assembly 40 during high-speed rotation, preventing wobbling or displacement of the tool assembly 40.

[0044] like Figure 5 As shown, the blade assembly 40 includes a blade shaft 41 and blades 42. The blade shaft 41 has a second mounting hole 411, and the blades 42 are disposed on the outer circumferential surface of the blade shaft 41. At least a portion of the first connecting shaft extends into the second mounting hole 411 to achieve a nested fit between the blade assembly 40 and the connecting structure 30. Thus, the blade shaft 41 in the blade assembly 40 is provided with the second mounting hole 411, and at least a portion of the first connecting shaft extends into it, achieving a nested fit between the blade assembly and the connecting structure 30. This ensures the precise positioning of the blade assembly within the food processor cup 20, allowing the blade assembly 40 to remain stably in the correct position during meat grinding or mixing, preventing displacement or shaking, and guaranteeing operational safety and consistent meat grinding results. Simultaneously, the nested connection between the first connecting shaft and the blade shaft 41 through the second mounting hole 411 forms a direct force transmission link, reducing energy loss during force transmission. Power is directly transmitted from the drive device 12 to the blade shaft 41, and then precisely acts on the blades 42 through the blade shaft 41, thereby improving the working efficiency of the food processor.

[0045] like Figure 3As shown, the first connecting shaft includes a first shaft segment 32 and a second shaft segment 33 connected to each other. The outer diameter D1 of the first shaft segment 32 is larger than the outer diameter D2 of the second shaft segment 33. A second gap is formed between the outer surface of the first shaft segment 32 and the wall of the second mounting hole 411, and a first gap is formed between the outer surface of the second shaft segment 33 and the wall of the second mounting hole 411. The end of the second shaft segment 33 furthest from the first shaft segment 32 forms the first end of the first connecting shaft. This arrangement ensures that the fit clearance between the tool shaft 41 of the tool assembly 40 and the first connecting shaft varies at different shaft segments. Because the first gap between the second shaft segment 33 and the tool shaft 41 is larger, it reduces the contact area during high-speed rotation, thereby significantly reducing friction and noise, providing a quieter and more comfortable operating environment for the user. Simultaneously, the smaller second gap between the first shaft segment 32 and the second mounting hole 411 helps to establish a tighter fit between the tool shaft 41 and the first connecting shaft, thus minimizing energy loss while ensuring accurate power transmission. Power is transmitted directly and efficiently from the drive unit 12 to the tool assembly 40 through the first shaft segment 32, making the rotation of the blade 42 smoother.

[0046] In this embodiment, the first connecting shaft adopts a shaft segment design with different outer diameters. The second gap and the first gap are achieved through the first shaft segment 32 and the second shaft segment 33. This not only improves the working efficiency and safety of the meat grinder, but also optimizes the product assembly and maintenance process, bringing a better user experience.

[0047] Optionally, the difference between the outer diameter D1 of the first shaft segment 32 and the outer diameter D2 of the second shaft segment 33 is greater than or equal to 0.1 mm. By setting the outer diameter difference between the first shaft segment 32 and the second shaft segment 33 to be greater than or equal to 0.1 mm, a significant stepped clearance is formed between the tool assembly 40 and the first connecting shaft, thereby reducing the contact area between the tool shaft 41 and the first connecting shaft during high-speed rotation, and thus significantly reducing frictional resistance. Simultaneously, despite the significant outer diameter difference, the tighter fit between the first shaft segment 32 and the second mounting hole 411 ensures the accuracy of power transmission and prevents any unnecessary wobbling or offset of the tool assembly 40 during rotation.

[0048] In this embodiment, the difference between the outer diameter D1 of the first shaft segment 32 and the outer diameter D2 of the second shaft segment 33 is 0.15 mm.

[0049] It should be noted that the value of the difference between the outer diameter D1 of the first shaft segment 32 and the outer diameter D2 of the second shaft segment 33 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the difference between the outer diameter D1 of the first shaft segment 32 and the outer diameter D2 of the second shaft segment 33 is 0.18 mm, or 0.20 mm, or 0.25 mm, or 0.28 mm, or 0.30 mm, or 0.50 mm, or 0.8 mm, or 1.0 mm, or 2.0 mm, or 5.0 mm, or 8.0 mm, or 10.0 mm.

[0050] Optionally, the length L1 of the first shaft segment 32 and the total length L of the first connecting shaft satisfy: 0.5L < L1. In this way, by setting the relationship between the length L1 of the first shaft segment 32 and the total length L of the first connecting shaft as 0.5L < L1, it means that the first shaft segment occupies a relatively large proportion of the first connecting shaft. Since the first shaft segment 32 forms a relatively tight fit with the tool shaft 41 in the tool assembly 40, the longer first shaft segment 32 provides a larger contact area and a longer axial support, thereby increasing the connection strength and stability between the tool assembly 40 and the connection structure 30, ensuring safety in the high-speed operation state. At the same time, as the main power transmission segment, the increase in the length of the first shaft segment 32 is beneficial to improving the efficiency of power transmission. The longer first shaft segment 32 can more effectively transmit the motor driving force from the first end of the first connecting shaft to the tool assembly smoothly, reducing the loss of energy during the transmission process, making the rotation of the blade 42 more uniform and powerful, and thus improving the working efficiency and meat grinding effect of the meat grinder.

[0051] Optionally, along the direction from the first shaft segment 32 to the second shaft segment 33, the outer diameter of the second shaft segment 33 gradually decreases; or, the outer diameter of the second shaft segment 33 first decreases and then increases. In this way, along the direction from the first shaft segment 32 to the second shaft segment 33, the outer diameter of the second shaft segment 33 gradually decreases, or shows a tapered or concave-convex change trend of first decreasing and then increasing. The above design further reduces the contact area between the tool assembly 40 and the first connecting shaft during rotation, especially in the part where the tool assembly has the heaviest load, effectively reducing the friction force and the heat generated by friction, thereby significantly reducing the wear of materials and extending the service life of the tool assembly 40 and the first connecting shaft. At the same time, the design of the change in the outer diameter of the second shaft segment 33 can better adapt to different rotation speeds of the tool assembly 40, ensuring the smoothness of power transmission in various operation modes. When the outer diameter gradually decreases, it can provide a more brisk rotation feeling; while the design of the outer diameter first decreasing and then increasing helps to maintain the best torque transmission of the tool assembly 40 at different speeds, avoiding fluctuations and unevenness in the power transmission process.

[0052] Such as Figure 2 and Figure 3As shown, the end of the first shaft segment 32 furthest from the second shaft segment 33 has a rounded corner 34. This rounded corner 34 significantly reduces stress concentration in this area, resulting in a more uniform stress distribution. This effectively improves the fatigue resistance of the first shaft segment 32 in this region and extends the service life of the meat grinder. Simultaneously, the rounded corner 34 improves the assembly interface between the first shaft segment 32 and the cutter shaft 41. During assembly, the rounded corner 34 acts as a guide, making it easier to align the first shaft segment 32 with the corresponding mounting holes, reducing the difficulty of component alignment during assembly. Furthermore, the rounded corner 34 also makes disassembly smoother, avoiding jamming or damage caused by sharp angles.

[0053] In this embodiment, the rounded corner 34 can reduce the risk of injury when the user accidentally comes into contact with the first shaft segment, and avoid scratches or cuts that may be caused by sharp corners.

[0054] Optionally, the second shaft segment 33 may have a single protrusion; or multiple protrusions may be spaced apart along the circumference and / or axial direction of the second shaft segment 33. This arrangement of one or more protrusions on the second shaft segment 33 creates additional engagement points between the blade assembly 40 and the first connecting shaft, thereby improving power transmission between the blade assembly 40 and the drive device 12 and ensuring the accuracy and stability of power transmission during high-speed rotation. Even when processing hard ingredients, it prevents the blade assembly 40 from slipping or deviating, improving the efficiency and quality of the meat grinder. Simultaneously, the protrusions increase the local thickness of the second shaft segment 33, enhancing its structural rigidity and resistance to deformation. Under high-intensity use or external impact, the protrusions effectively resist bending or twisting of the shaft segment due to excessive load, improving the structural strength of the second shaft segment 33 and extending the service life of the meat grinder. Furthermore, the contact between the protrusions and the blade assembly 40 may create a small seal, reducing the possibility of moisture or food residue entering the motor or bearings, thus enhancing the water resistance of the meat grinder.

[0055] Alternatively, the food processor can be a meat grinder.

[0056] Example 2

[0057] The difference between the food processor in Example 2 and that in Example 1 is that the structure of the first connecting shaft is different.

[0058] In this embodiment, a groove is provided on the outer surface of the first connecting shaft, and a first gap is formed between the groove and the wall of the second mounting hole 411; wherein, the groove extends circumferentially along the first connecting shaft; and / or, the groove is an arc-shaped groove or an annular groove. Thus, by providing a groove on the outer surface of the first connecting shaft, and forming a first gap between the groove and the wall of the second mounting hole 411, the contact area between the blade assembly and the connecting shaft can be reduced, thereby reducing frictional resistance and noise generated during the operation of the food processor. At the same time, the above-mentioned design allows for more flexible selection of the groove shape to meet different usage needs and working conditions, improving the processing flexibility of the operator.

[0059] Optionally, there may be one groove; or there may be multiple grooves spaced apart along the axial direction of the first connecting shaft. In this way, whether a single groove or multiple grooves are used, the frictional contact area between the first connecting shaft and the cutter assembly 40 can be significantly reduced. Specifically, a single elongated groove can provide a stable, low-friction path, while multiple grooves spaced apart along the axial direction can disperse friction points, reduce overall frictional resistance, thereby improving motor efficiency, reducing energy consumption, and extending the service life of the meat grinder.

[0060] Optionally, the groove can be at least one of a rectangular groove, a V-shaped groove, or a semi-circular groove. This design allows for greater flexibility in selecting the shape of the groove to meet different usage requirements and working conditions, and also improves the processing flexibility of the workers.

[0061] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0062] The food processor includes a body, a blending cup, and a blade assembly. The body includes a cover and a drive unit housed within the cover. The blending cup is detachably connected to the cover, and a connecting structure is provided on the inner bottom surface of the blending cup. The drive unit is driven to the first end of the blade assembly to drive the blade assembly to rotate. The second end of the blade assembly and the connecting structure are nested together. A first gap exists between a portion of the connecting structure and the second end of the blade assembly, and a second gap exists between a portion of the connecting structure and the second end of the blade assembly. The first gap is larger than the second gap. Thus, within the allowable length of the fit between the connecting structure and the blade assembly, the connecting structure and the blade assembly do not contact each other at the first gap, or the contact area at the first gap is minimal. During the rotation of the blade assembly, the aforementioned design of the first and second gaps reduces the contact area between the connecting structure and the blade assembly, especially in areas where significant friction occurs during high-speed rotation. This reduces unnecessary friction and solves the problem in existing technologies where high friction between the fixed shaft and the blade assembly affects the lifespan of the food processor and the user experience. This reduces noise during operation, extends the lifespan of the food processor, and improves the user experience. Meanwhile, the clearance fit between the connecting structure and the cutting tool assembly ensures a stable connection between the cutting tool assembly and the connecting structure, preventing the cutting tool assembly from shaking or falling off due to an excessively loose fit, thus enhancing operational safety and ensuring the effectiveness and uniformity of the meat grinding process.
