Description

An angle-adjustable blade assembly for a food processor Technical Field

[0001] This utility model relates to the field of knife assembly technology, and in particular discloses an angle-adjustable knife assembly for a food processor. Background Technology

[0002] As people's living standards continue to improve, food processors are becoming increasingly widely used. The blade is the core component of a food processor, and its performance determines the quality of the processor. Traditional food processor blades typically use a fixed-angle design, making it difficult to flexibly adjust the cutting angle according to the characteristics of the ingredients or processing needs, thus limiting cutting efficiency and results. In addition, existing blade components are mostly integrated structures, which are inconvenient to disassemble and assemble and have high maintenance costs. At the same time, the blade layout is simple and the flow guiding effect is poor, which can easily cause food to splatter or accumulate. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an angle-adjustable blade assembly for a food processor.

[0004] To achieve the above objectives, this utility model provides an angle-adjustable blade assembly for a food processor, comprising a blade holder assembly and a first blade assembly. The first blade assembly includes a bushing, a first blade disposed on the outside of the bushing, and a shaft hole in the bushing. The first blade assembly is mounted on the blade holder assembly via the shaft hole. The blade holder assembly includes a connecting shaft, and a second blade assembly is disposed at the lower part of the connecting shaft. The second blade assembly includes a body portion and a second blade disposed on the outside of the body portion. The bushing is sleeved on the outside of the connecting shaft, and a first limiting member is provided on the side wall of the connecting shaft. A second limiting member is provided on the inner side wall of the bushing to cooperate with the first limiting member. The blades of the first blade assembly and the blades of the second blade assembly are offset along the central axis of the connecting shaft.

[0005] The first and second blades work together to cut food from different positions and angles, improving cutting efficiency and effectiveness. The cooperation between the first and second limiting components provides the basis for adjusting the angle of the blade assembly, meeting various cooking needs. In practice, the bushing of the first blade assembly is first installed on the connecting shaft of the blade holder assembly through the shaft hole, so that the second limiting component on the inner side wall of the bushing cooperates with the first limiting component on the side wall of the connecting shaft. When angle adjustment is needed, the limiting is released by utilizing the cooperation between the two, the first blade assembly is rotated to the appropriate angle, and then the limiting is reset to achieve the angle adjustment function.

[0006] The first limiting member includes a first protrusion extending along the central axis of the connecting shaft, and the first protrusion also has a protrusion surrounding the central axis of the connecting shaft.

[0007] The second limiting member includes a second protrusion that is vertically disposed on the inner side wall of the bushing. The top end of the second protrusion abuts against the protrusion to limit the first cutter head assembly on the cutter holder assembly.

[0008] The first convex rib extending along the central axis of the connecting shaft provides precise guidance for the installation and movement of the first blade assembly, ensuring stability during installation. The protrusion on the first convex rib cooperates with the second convex rib inside the bushing, further enhancing the limiting function and ensuring the stable axial position of the first blade assembly, effectively preventing shaking and displacement during operation. The bushing of the first blade assembly is installed on the connecting shaft of the blade holder assembly through the shaft hole. During installation, the second convex rib inside the bushing must be aligned with the first convex rib on the connecting shaft. When the food processor is in normal working condition, the top of the second convex rib abuts against the protrusion on the first convex rib, thus reliably limiting the first blade assembly on the blade holder assembly and ensuring stable operation of the blade assembly. When the angle of the blade assembly needs to be adjusted, the operator only needs to apply a certain external force to disengage the second convex rib from the protrusion, at which point the first blade assembly can rotate around the connecting shaft.

[0009] The protrusion has a notch with rounded corners on both sides, and the second limiting member is released from contact with the first limiting member through the notch.

[0010] To adjust the angle of the blade assembly, the operator applies a certain external force, causing the second protrusion to slide into the notch along the rounded corners on both sides, thus releasing the second limiting member from contact with the first limiting member. At this point, the first blade assembly can rotate freely around the connecting shaft. This design makes the angle adjustment of the blade assembly more flexible and convenient, allowing users to quickly adjust the blade angle according to different cooking needs.

[0011] The first blade is provided in three groups, and the three groups of first blades are arranged radially at equal intervals on the bushing. Along the central axis of the bushing, the first group of first blades, the second group of first blades, and the third group of first blades are arranged at intervals.

[0012] The radially evenly spaced distribution ensures that the food is cut multiple times by different blades during rotation, reducing missed areas and improving processing uniformity. The radial layout can reduce the unbalanced force during high-speed rotation, reducing vibration and noise. The three sets of blades are evenly distributed in the axial direction to form a stepped cutting layer, which can cover the movement trajectory of the food at different heights, reducing the processing dead angles of traditional single-layer blades and improving the uniformity of food crushing.

[0013] The bushing is embedded in three sets of first blades. The first blade has an annular portion inside the side wall of the bushing and a blade portion outside the bushing. The annular portion has a snap-fit ​​that engages with the bushing. An outer convex ring is formed on the outer side of the bushing. The outer convex ring has three parallel straight convex arcs. Along the central axis of the bushing, the three straight convex arcs are spaced apart from each other. The three sets of first blades protrude from the bushing through the three straight convex arcs respectively.

[0014] This bushing embedding structure fixes the annular portion of the three sets of first blades to the bushing by engaging them, and uses three spaced flat convex arcs on the outer side of the bushing to achieve precise positioning and stable support for the blades. This not only improves the bonding strength and operational stability between the blades and the bushing, but also optimizes the stress distribution and balance of the overall structure through the spaced distribution of the convex arcs. This allows the blades to maintain efficient cutting function while also having the advantages of easy installation and maintenance, strong resistance to vibration and wear, and effectively extending the service life of the equipment.

[0015] The top of the connecting shaft is integrally formed with a drive shaft, and the tool assembly also includes a seal sleeved on the drive shaft.

[0016] The top of the connecting shaft and the drive shaft are integrally molded, eliminating the assembly gap of traditional split shaft structures and ensuring coaxial accuracy of power transmission. This design reduces tool vibration caused by loose shaft connections, improving cutting stability. The inner hole of the seal and the outer diameter of the drive shaft achieve radial sealing through an interference fit, preventing food residue or liquid from seeping into the shaft.

[0017] The outer sidewall of the bushing is recessed inward with a groove, which is located above the first blade. The groove facilitates the user to apply rotational torque to detach or install the first blade assembly from the tool holder assembly.

[0018] Each blade is equipped with a protective sleeve. The blade is crescent-shaped, and the protective sleeve is placed on the outside of the blade. One end of the protective sleeve is used to abut against the bushing.

[0019] The blade is secured by the engagement of the bushing with the annular portion of the crescent-shaped blade, and the three spaced, flat convex arcs on the outer side achieve precise positioning and support of the blade, significantly improving structural stability. At the same time, the protective sleeve on the outer side of the blade abuts against the bushing at one end. The protective sleeve can protect the blade assembly when the food processor is not in operation, reducing wear. The protective sleeve abuts against the bushing at the other end, reducing the risk of cuts when the user handles the blade, thus improving safety.

[0020] The blade assembly also includes a fixing component that rotatably engages with the external food processor housing. The bottom of the connecting shaft is provided with an assembly hole, through which the connecting shaft can be detachably mounted on the fixing component of the external food processor housing. The fixing component has a wear-resistant sleeve that rotatably engages with the food processor housing.

[0021] The fixing component includes a base fixed to the external food processor housing, a second shaft body provided above the base, a wear-resistant sleeve protruding from the base, and multiple sets of limiting parts radially arranged on the side of the second shaft body. The limiting parts include a first vertical bar and a second vertical bar parallel to the first vertical bar. The first vertical bar and the second vertical bar together form a sliding cavity. The bottom mounting hole sidewall of the connecting shaft is provided with a protruding strip, which can slide axially along the sliding cavity.

[0022] The blade assembly is detachably installed via a mounting hole at the bottom of the connecting shaft and a fixing component. This design simplifies the installation and removal of the blade assembly from the food processor. When cleaning, replacement, or maintenance is required, the user can easily remove the blade assembly from the food processor housing, enhancing its maintainability. The fixing component's base is secured to the external food processor housing, providing a stable support foundation for the entire blade assembly. Multiple limiting parts on the side of the second shaft cooperate with the protruding strips on the sidewall of the mounting hole at the bottom of the connecting shaft, further enhancing the stability of the blade assembly within the food processor. During operation, this effectively reduces shaking and displacement, ensuring a smooth cutting process and improving cutting efficiency and quality.

[0023] The cutting edge of the first blade or the second blade is a wavy, serrated, or serrated blade. The wavy shape increases the contact points between the blade and the food during cutting, dispersing the cutting force more effectively. When cutting fibrous foods (such as celery and seaweed), the wavy blade can more easily cut into and sever the fibers, reducing the force required for cutting and minimizing slippage of the food during the cutting process, thus improving cutting efficiency. A saw-like serrated design is effective when cutting harder foods (such as carrots and potatoes). The serrations first cut into the surface of the food and then gradually penetrate deeper, significantly improving the cutting effect for hard, difficult-to-cut foods. A curved blade allows for a gradual contact between the blade and the food during cutting, better adapting to the shape of the food. When cutting round or oval fruits (such as apples and oranges), the curved blade can cut along the contour of the fruit, reducing damage and improving the integrity of the cut.

[0024] The beneficial effects of this utility model are as follows: The adjustable blade assembly of this food processor achieves multi-functional integration through innovative structural design: The angle adjustment mechanism uses the cooperation of the first and second limiting parts, which enables the blade assembly to not only be stably limited to ensure operational stability, but also to flexibly adjust the cutting angle by releasing the limit through external force to meet the processing needs of different ingredients; Three sets of radially equally spaced crescent-shaped blades, combined with the protective sleeve design, optimize the uniformity of cutting coverage through a stepped layout, and use the protective sleeve to fix the blades and optimize the cutting force distribution, reducing the risk of wear; The bushing embedded molding structure combined with the three straight convex arc positioning of the outer convex ring enhances the bonding strength between the blade and the bushing while improving vibration resistance and wear resistance; Combined with the one-piece molded drive shaft and seals, it ensures transmission accuracy and hygiene protection; The detachable fixing part design, combined with the wear-resistant sleeve and sliding cavity limiting structure, simplifies disassembly and maintenance while improving overall operational stability, comprehensively achieving the technical effects of efficient cutting, flexible adjustment, safety and durability, and convenient maintenance.

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0036] Please refer to Figures 1 to 8. This utility model discloses an angle-adjustable blade assembly for a food processor, comprising a blade holder assembly 1 and a first blade assembly 2. The first blade assembly 2 includes a bushing 3 and a first blade 4 disposed on the outside of the bushing 3. The bushing 3 has a shaft hole 5, and the first blade assembly 2 is mounted on the blade holder assembly 1 via the shaft hole 5. The blade holder assembly 1 includes a connecting shaft 6, and a second blade assembly 7 is disposed at the lower part of the connecting shaft 6. The second blade assembly 7 includes a body portion 8 and a second blade 9 disposed on the outside of the body portion 8. The bushing 3 is sleeved on the outside of the connecting shaft 6. A first limiting member 11 is provided on the side wall of the connecting shaft 6, and a second limiting member 12, which cooperates with the first limiting member 11, is provided on the inner side wall of the bushing 3. The blades of the first blade assembly 2 and the second blade assembly 7 are offset along the central axis of the connecting shaft 6.

[0037] The first blade 4 and the second blade 9 work together to cut ingredients from different positions and angles, improving cutting efficiency and effectiveness. The cooperation of the first limiting member 11 and the second limiting member 12 provides a basis for the angle adjustment of the blade assembly, meeting different cooking needs. In specific implementation, the bushing 3 of the first blade assembly 2 is first installed on the connecting shaft 6 of the blade holder assembly 1 through the shaft hole 5, so that the second limiting member 12 on the inner side wall of the bushing 3 cooperates with the first limiting member 11 on the side wall of the connecting shaft 6. When the angle needs to be adjusted, the limiting is released by utilizing the cooperation between the two, the first blade assembly 2 is rotated to the appropriate angle, and then the limiting is reset to achieve the angle adjustment function.

[0038] The first limiting member 11 includes a first protrusion 13 extending along the central axis of the connecting shaft 6, and the first protrusion 13 is also provided with a protrusion 14 surrounding the central axis of the connecting shaft 6.

[0039] The second limiting member 12 includes a second protrusion 15 vertically disposed on the inner side wall of the bushing 3. The top end of the second protrusion 15 abuts against the protrusion 14 to limit the first cutter head assembly 2 on the cutter holder assembly 1.

[0040] The first protrusion 13, extending along the central axis of the connecting shaft 6, provides precise guidance for the installation and movement of the first blade assembly 2, ensuring stability during installation. The protrusion 14 on the first protrusion 13 cooperates with the second protrusion 15 on the inner side of the bushing 3, further enhancing the limiting function and ensuring the stable axial position of the first blade assembly 2, effectively preventing shaking and displacement during operation. The bushing 3 of the first blade assembly 2 is installed on the connecting shaft 6 of the blade holder assembly 1 through the shaft hole 5. During installation, the second protrusion 15 on the inner side of the bushing 3 should be aligned with the first protrusion 13 on the connecting shaft 6. When the food processor is in normal working condition, the top of the second protrusion 15 abuts against the protrusion 14 on the first protrusion 13, thus reliably limiting the first blade assembly 2 on the blade holder assembly 1, ensuring stable operation of the blade assembly. When the angle of the tool assembly needs to be adjusted, the operator only needs to apply a certain external force to disengage the second protrusion 15 from the protrusion 14, at which point the first tool head assembly 2 can rotate around the connecting shaft 6.

[0041] The protrusion 14 is provided with a notch 16, and the notch 16 has rounded corners on both sides. The second limiting member 12 is released from contact with the first limiting member 11 through the notch 16.

[0042] To adjust the angle of the blade assembly, the operator applies a certain external force, causing the second protrusion 15 to slide into the notch 16 along the rounded corners on both sides, thereby releasing the second limiting member 12 from contact with the first limiting member 11. At this time, the first blade assembly 2 can rotate freely around the connecting shaft 6. This design makes the angle adjustment of the blade assembly more flexible and convenient, allowing users to quickly adjust the blade angle according to different cooking needs.

[0043] The first blade 4 is provided in three groups. The three groups of first blades 4 are arranged radially at equal intervals on the bushing 3. Along the central axis of the bushing 3, the first group of first blades 4, the second group of first blades 4, and the third group of first blades 4 are arranged at intervals.

[0044] The radially evenly spaced distribution ensures that the food is cut multiple times by different blades during rotation, reducing missed areas and improving processing uniformity. The radial layout can reduce the unbalanced force during high-speed rotation, reducing vibration and noise. The three sets of blades are evenly distributed in the axial direction to form a stepped cutting layer, which can cover the movement trajectory of the food at different heights, reducing the processing dead angles of traditional single-layer blades and improving the uniformity of food crushing.

[0045] The bushing 3 is embedded in three sets of first blades 4. The first blade 4 has an annular portion 100 located inside the side wall of the bushing 3 and a blade portion 101 located outside the bushing 3. The annular portion 100 has a snap 102 that engages with the bushing 3. An outer convex ring 103 is formed on the outer side of the bushing 3. The outer convex ring 103 has three parallel straight convex arcs 104. Along the central axis of the bushing 3, the three straight convex arcs 104 are spaced apart from each other. The three sets of first blades 4 protrude from the bushing 3 through the three straight convex arcs 104 respectively.

[0046] The bushing 3 embedded molding structure fixes the annular part 100 of the three sets of first blades 4 to the bushing 3 by engaging and fixing them together. It also uses three spaced flat convex arcs 104 on the outer side of the bushing 3 to achieve precise positioning and stable support of the blades. This not only improves the bonding strength and operational stability between the blades and the bushing 3, but also optimizes the stress distribution and balance of the overall structure through the spaced distribution of the convex arcs. This allows the blades to maintain efficient cutting function while also having the advantages of easy installation and maintenance and strong resistance to vibration and wear, effectively extending the service life of the equipment.

[0047] The top of the connecting shaft 6 is integrally formed with a drive shaft 17, and the tool assembly also includes a seal 18 sleeved on the drive shaft 17.

[0048] The top of the connecting shaft 6 and the drive shaft 17 are integrally molded, eliminating the assembly gap of the traditional split shaft structure and ensuring the coaxial accuracy of power transmission. This design can reduce tool vibration caused by loose shaft connection and improve cutting stability. The inner hole of the seal 18 and the outer diameter of the drive shaft 17 achieve radial sealing through interference fit to prevent food residue or liquid from seeping into the shaft.

[0049] The outer sidewall of the bushing 3 is recessed inward with a groove 19, which is located above the first blade 4. The groove 19 facilitates the user to apply rotational torque to remove or install the first cutter head assembly 2 from the cutter holder assembly 1.

[0050] Each blade is equipped with a protective sleeve 105. The blade is crescent-shaped, and the protective sleeve 105 is fitted on the outside of the blade. One end of the protective sleeve 105 is used to abut against the bushing 3.

[0051] The blade is secured by engaging the bushing 3 with the annular portion 100 of the crescent-shaped blade. Combined with the three spaced, straight convex arcs 104 on the outer side, the blade is precisely positioned and supported, significantly improving structural stability. Meanwhile, the protective sleeve 105 fitted on the outer side of the blade abuts against the bushing 3 at one end. The protective sleeve 105 can protect the blade assembly when the food processor is not in operation, reducing wear. The protective sleeve 105 abuts against the bushing 3 at one end, reducing the risk of cuts when the user handles the blade, thus improving safety.

[0052] The blade assembly also includes a fixing member 22 that rotates with the outer food processor housing. The bottom of the connecting shaft 6 is provided with an assembly hole 23. The connecting shaft 6 can be detachably installed on the fixing member 22 of the outer food processor housing via the assembly hole 23. The fixing member 22 has a wear-resistant sleeve that rotates with the food processor housing.

[0053] The fixing component 22 includes a base 24 fixed to the external food processor housing, a second shaft 25 provided above the base 24, a wear-resistant sleeve exposed on the base 24, and multiple sets of limiting parts 26 radially arranged on the side of the second shaft 25. The limiting part 26 includes a first vertical bar 27 and a second vertical bar 28 parallel to the first vertical bar 27. The first vertical bar 27 and the second vertical bar 28 together form a sliding cavity 29. The bottom mounting hole 23 of the connecting shaft 6 is provided with a protruding strip 31 on the side wall, and the protruding strip 31 can slide along the axial direction of the sliding cavity 29.

[0054] The blade assembly is detachably installed via the mounting hole 23 at the bottom of the connecting shaft 6 and the fixing member 22. This design makes the installation and removal of the blade assembly on the food processor simple and convenient. When the blade assembly needs cleaning, replacement, or maintenance, the user can easily remove it from the food processor housing, making operation convenient and improving the maintainability of the blade assembly. The base 24 of the fixing member 22 is fixed to the external food processor housing, providing a stable support foundation for the entire blade assembly. Multiple sets of limiting parts 26 on the side of the second shaft 25 cooperate with the protruding strip 31 on the side wall of the mounting hole 23 at the bottom of the connecting shaft 6, further enhancing the stability of the blade assembly in the food processor. When the blade assembly is working, it can effectively reduce shaking and displacement, ensuring a smooth cutting process, thereby improving cutting efficiency and quality.
