Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular discloses a multi-functional food processor. Background Technology

[0002] In existing food processing equipment, most food processors have relatively limited functions, typically offering only one cutting mode: slicing, shredding, or dicing. While some devices attempt to integrate multiple functions, the disassembly and interchangeability of related cutting blade components (such as slicing / shredding blades and dicing blades) are often complex, installation accuracy relies on user feel, and the reliability of the power transmission is poor. Furthermore, existing cutting equipment generally lacks precise control over the processing speed of ingredients with varying degrees of hardness. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a multi-functional food processor that integrates slicing, shredding and dicing functions, and realizes quick blade replacement and smooth power transmission.

[0004] To achieve the above objectives, the present invention provides a multifunctional food processor, comprising a main unit assembly, a lid, and a food processor cup; further comprising a first blade assembly, a second blade assembly, and a feeding assembly; the first blade assembly and the second blade assembly are alternatively coupled to the main unit assembly; the first blade assembly comprises a first blade disc, a shredder blade disposed on one side of the first blade disc, a slicing blade disposed on the other side of the first blade disc, and a first transmission member for drivingly connecting the first blade disc to the main unit assembly; the shredder blade is used to perform shredding operations, and the slicing blade is used to perform slicing operations; the second blade assembly comprises a second blade disc, a mesh blade disposed on the second blade disc, a cross-cutting blade rotatably disposed above the mesh blade, and a second transmission member for drivingly connecting the cross-cutting blade to the main unit assembly; the main unit assembly is used to drive the first blade disc or the cross-cutting blade to rotate to perform cutting operations; the food processor cup has a receiving cavity, and the feeding assembly comprises a feeding cylinder communicating with the receiving cavity and a pressing member movably disposed within the feeding cylinder; the first blade assembly or the second blade assembly is located between the outlet of the feeding cylinder and the inlet of the receiving cavity of the food processor cup.

[0005] Furthermore, the cutter has a carrier plate and cutter bodies arranged in a crisscross pattern on the carrier plate, with the cutting edges of the cutter bodies facing the material pressing part of the cross-cutting cutter; the second cutter disc is provided with mounting holes, and the carrier plate is detachably installed into the mounting holes through a snap-fit ​​and slot structure.

[0006] Furthermore, the shape and structure of the pressing component are adapted to the pressing cylinder. The pressing component is cup-shaped, and the bottom of the pressing component is provided with multiple flexible protrusions to resist the material and prevent the material from moving inside the pressing cylinder.

[0007] Furthermore, a flexible protective ring is provided on the top of the pressing component. The protective ring is made of silicone, while the pressing component is made of rigid plastic. The protective ring is either fitted onto or separately injection molded onto the top of the pressing component.

[0008] Furthermore, a rotary locking mechanism is provided between the second tool assembly and the cover. When the second tool assembly is placed into the cover and rotates around its own axis by a preset angle under the action of external force, the rotary locking mechanism passes the locking peak position, thereby realizing the fixed connection between the second tool assembly and the cover.

[0009] Furthermore, the rotary locking mechanism includes a guide bar disposed on the outer periphery of the second cutter disc, a stop protrusion, a guide rail disposed on the inner side wall of the cover, and a stop groove; the guide bar extends circumferentially along the second cutter disc, and the stop protrusion extends radially and circumferentially along the second cutter disc; when the second cutter disc rotates, the guide bar moves along the guide rail, causing the stop protrusion to enter the stop groove along the guide rail, thereby achieving a fixed engagement between the second cutter assembly and the cover.

[0010] Furthermore, an arc-shaped guide is provided on one side of the stop slot to guide the stop to protrude into the slot.

[0011] Furthermore, it also includes a speed control unit; the main unit has a head housing and a drive motor located inside the head housing; the speed control unit includes a knob unit rotatably mounted on the head housing and a voltage adjustment module that works in conjunction with the knob unit; the voltage adjustment module includes a potentiometer, which has an arc-shaped resistive element and a conductive contact that slides along the arc-shaped resistive element; the knob unit reciprocates to drive the conductive contact to slide along the surface of the resistive element, so as to continuously adjust the voltage input to the drive motor, thereby adjusting the output speed of the drive motor.

[0012] Furthermore, it also includes a reduction gear module; the reduction gear module is detachably mounted on the cover; the reduction gear module includes a first drive shaft, a first gear disposed at the output end of the first drive shaft, a second gear meshing with the first gear, a third gear meshing with the second gear, and a second drive shaft disposed at the output end of the third gear; the diameter of the first gear is smaller than the diameter of the third gear and smaller than the diameter of the second gear; the second drive shaft is used for transmission cooperation with the first transmission component or the second transmission component.

[0013] Preferably, both the first and second transmission components are transmission structures with irregularly shaped splined shafts, and the second transmission shaft is a transmission sleeve with an internal splined structure.

[0014] Furthermore, in this embodiment, in order to achieve safe engagement and power connection between the main unit and the cover, the cover is provided with a concave receiving groove, and a bowl-shaped shell is provided in the receiving groove. The reduction gear module is fixedly installed in the receiving groove by bolts and the bowl-shaped shell.

[0015] The bottom of the bowl-shaped housing has a first through hole, through which the first drive shaft of the reduction gear module extends upward and is exposed. The lower end of the head housing of the main unit has a fitting part that matches the shape of the bowl-shaped housing. Inside the main unit, the transmission cylinder at the power output end of the drive motor is provided with a first elastic element and a contact element.

[0016] The cover is provided with a second through hole, through which the irregular spline shaft passes and engages with the internal spline of the second transmission shaft, so that the first transmission component or the second transmission component can be driven and cooperated with the reduction gear module.

[0017] During the actual assembly process, when the fitting part of the main component has not yet been pressed and locked with the bowl-shaped housing, the first elastic element drives the abutment to push the first transmission shaft outward, so that it is disengaged from the spline meshing surface in the transmission cylinder. At this time, the power transmission between the main component and the reduction gear module is completely disconnected. When the user presses the fitting part of the main unit down into place along the bowl-shaped housing, the first drive shaft overcomes the resistance of the first elastic element and is pushed into the drive cylinder, establishing a stable internal spline engagement, thereby realizing the conduction of power.

[0018] Furthermore, the head housing is also equipped with a micro switch electrically connected to the drive motor. A pressing part is movably provided on the top of the head housing. When the first drive shaft and the drive cylinder are engaged in the transmission after being pressed into place, the user can press down the pressing part to trigger the micro switch to close and connect the power supply to the drive motor.

[0019] Furthermore, the micro switch and the voltage regulation module are electrically connected together in the control circuit of the drive motor, and the two are connected in series in circuit logic. The voltage regulation module is mainly used to continuously adjust the voltage input to the drive motor according to the rotation angle of the knob unit to achieve stepless speed regulation of the motor; while the micro switch serves as the physical on / off control switch for the main power supply of the drive motor circuit.

[0020] Furthermore, the main unit also includes a first transmission gear set driven by a drive motor and disposed inside the head housing; the output end of the first transmission gear set is provided with a transmission cylinder, and the transmission cylinder is provided with an internal spline structure adapted to the outer contour of the first transmission shaft; the transmission cylinder is provided with a first elastic element, and the free end of the first elastic element is provided with an abutment element, which is used to abut the end face of the free end of the first transmission shaft; the main unit is used to press and fit with the cover, and when the main unit and the cover are pressed into place, the first transmission shaft overcomes the resistance of the first elastic element and inserts into the transmission cylinder to establish a transmission fit, so that the power transmission is conducted.

[0021] Furthermore, the rotation axes of the second drive shaft, the first drive member, and the second drive member coincide with the central axis of the blending cup; the rotation axis of the first drive shaft is offset from the central axis of the blending cup, and the rotation axis of the first drive shaft coincides with the rotation axis of the output end of the first drive gear set of the main unit.

[0022] Furthermore, the slicing blade is detachably mounted on the first blade disc; the first blade disc has a discharge hole near the slicing blade for the material to pass through after slicing, and the discharge hole is connected to the receiving cavity of the cooking cup.

[0023] Furthermore, in this embodiment, in order to achieve rapid disassembly and assembly and stable transmission between the first cutter head and the power output end, a detachable rotary engagement structure is provided between the middle part of the first cutter head and the first transmission component.

[0024] Furthermore, a rotary engagement structure is provided between the first transmission component and the first cutter head.

[0025] The top of the first transmission component is provided with a spline hole for power adaptation with the second transmission shaft. The rotary engagement structure includes multiple wedge-shaped hooks protruding from the outer periphery of the top of the first transmission component. The wedge-shaped hooks are distributed circumferentially along the first transmission component. The main body of each wedge-shaped hook protrudes radially outward. The top end face of the wedge-shaped hook is provided with an inclined guide surface or a stepped guide slope. The bottom of the wedge-shaped hook is provided with a support plane that cooperates with the first cutter head and an anti-reverse locking position.

[0026] Correspondingly, the rotary engagement structure also includes a central mounting hole in the middle of the first cutter head for the top of the first transmission component to pass through. The inner wall of the central mounting hole is provided with a groove and an inclined protrusion that correspond one-to-one with the number and position of the wedge-shaped hooks. The opening size of the groove is adapted to the contour of the wedge-shaped hook so that it can be inserted without interference. The inclined protrusion extends circumferentially along the central mounting hole, and a smooth sliding guide surface is provided at the junction of the groove and the inclined protrusion.

[0027] During actual installation, the user first inserts the top of the first transmission component into the center mounting hole of the first cutter head and accurately aligns each wedge-shaped hook with the slide groove. Then, the user operates the first transmission component to rotate relative to the first cutter head around its own axis. The wedge-shaped hooks will slide into the slide groove along the sliding guide surface. During the radial rotation and axial sliding process, the wedge-shaped hooks pass the locking peak position along the sliding guide surface, so that the support plane of the wedge-shaped hooks fits tightly with the side wall of the inclined protrusion. At the same time, the anti-retraction locking position on the wedge-shaped hooks abuts against the top wall of the inclined protrusion, preventing it from retracting in the opposite direction.

[0028] Furthermore, regarding the power transmission path, the top of the first transmission component is provided with an internal spline hole, and an irregular spline shaft is installed inside the internal spline hole. The end of the second transmission shaft in the reduction gear module is provided with an internal spline structure for inserting the irregular spline shaft. The irregular spline shaft is inserted into the internal spline hole of the second transmission shaft, thereby establishing an anti-slip meshing transmission fit between the two, so that the power can be smoothly transmitted to the first transmission component.

[0029] Meanwhile, to ensure sufficient radial and axial stability of the first transmission component during high-speed rotation, an upwardly protruding limiting post is detachably fixed to the bottom of the cooking cup by bolts. The top surface of the limiting post is smoothed, or a rolling bearing structure is added to it.

[0030] The bottom center of the first transmission component has a slot that matches the outer diameter of the limiting post. During assembly, the slot at the bottom of the first transmission component is directly fitted onto the limiting post.

[0031] Furthermore, the bottom of the cooking cup is fitted with an anti-slip mat made of silicone.

[0032] In actual operation, the motor drives the reduction gear module to rotate the second transmission shaft. The second transmission shaft drives the first transmission component to rotate through the meshing of internal and external splines. The first transmission component then drives the first cutter head to perform high-speed cutting operations through the aforementioned rotational engagement structure. The limiting post serves as a rotational axis support for the bottom of the first transmission component, allowing the first transmission component to rotate stably around the central axis of the limiting post. This effectively reduces radial runout during transmission and significantly improves the overall transmission stability and service life of the machine.

[0033] Furthermore, the feed cylinder is offset from the central axis of the cooking cup.

[0034] Furthermore, the cross-cutting blade has a cutting edge that extends upward at an angle away from the mesh blade and a pressing part that extends downward at an angle close to the mesh blade. When the main unit drives the cross-cutting blade to rotate, the cutting edge cuts the material into flakes, and the pressing part pushes the flakes cut by the cutting edge through the mesh blade to form small pieces that fall into the receiving cavity of the cooking cup.

[0035] Furthermore, the first blade disc is provided with multiple balance holes, which are distributed on both sides of the slicing blade to balance the center of gravity of the first blade disc.

[0036] Furthermore, the slicing blade has multiple stamped and stretched slicing holes, which are divided into multiple groups. Each group of slicing holes is arranged along the radial direction of the first cutter disc, with each row including 3-5 slicing holes. Multiple rows of slicing holes are arranged circumferentially around the first cutter disc. The cross-section of the slicing holes is lens-shaped or elongated elliptical.

[0037] Furthermore, it also includes a limiting mechanism; the limiting mechanism includes a protective plate and a stop rib plate rotatably mounted on the second cutter head, the protective plate having a U-shaped portion, and an elastic locking protrusion provided on the inner side wall of the end of the U-shaped portion near its rotation axis; the second cutter assembly also includes a cutter guard ring fixedly connected to the outer periphery of the cross-cutting blade, the cutter guard ring being used for alignment and assembly with the second cutter head; when the cutter guard ring is located inside the second cutter head, the protective plate is rotated to cause the elastic locking protrusion to pass over the stop rib plate and enter the locking position, so that the cutter guard ring is axially limited and fixed with the second cutter head.

[0038] The beneficial effects of this invention are as follows: This invention integrates slicing, shredding, and dicing functions into a single unit through a replaceable dual-blade system design, expanding the applicability of the equipment and effectively saving kitchen space. The detachable modular structure of the blade assembly allows users to quickly switch between different cutting modes without the need for special tools, making operation extremely convenient. Combined with the speed control unit and the safety clutch interlock structure between the main unit and the blades, it not only precisely matches the cutting speed of different ingredients but also effectively prevents accidental start-up when the machine is not properly installed, fundamentally improving the stability and safety of equipment operation.

[0041] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0042] Please see Figures 1 to 16As shown, a multi-functional food processor of the present invention includes a main unit assembly 1, a cover 2, and a food processor cup 3; it also includes a first blade assembly 4, a second blade assembly 5, and a feeding assembly 6; the first blade assembly 4 and the second blade assembly 5 can be interchangeably coupled with the main unit assembly 1 for transmission according to processing requirements; the cover 2 is used to support and lock the first blade assembly 4, the second blade assembly 5, and the transmission components, while the food processor cup 3 is used to hold ingredients and form a support at the bottom.

[0043] Specifically, the first tool assembly 4 includes a disc-shaped first cutter disc 41, a shredder 42 disposed on one side of the first cutter disc 41, a slicing blade 43 disposed on the other side of the first cutter disc 41, and a first transmission member 44 for drivingly connecting the first cutter disc 41 with the main unit assembly 1; wherein the shredder 42 is used to perform shredding operations, and the slicing blade 43 is used to perform slicing operations.

[0044] The second tool assembly 5 includes a second cutter head 51, a mesh cutter 52 disposed on the second cutter head 51, a cross-cutting blade 53 rotatably disposed above the mesh cutter 52, and a second transmission member 55 for drivingly connecting the cross-cutting blade 53 to the main unit assembly 1.

[0045] The main unit 1 is used to drive the first cutter head 41 or the cross-cutting blade 53 to rotate to perform the cutting action; the cooking cup 3 has a receiving cavity 31, and the feeding assembly 6 includes a feeding cylinder 61 communicating with the receiving cavity 31 and a pressing member 62 movably disposed in the feeding cylinder 61.

[0046] In the assembled state, the first cutter assembly 4 or the second cutter assembly 5 is located between the outlet of the feed cylinder 61 and the inlet of the receiving cavity 31 of the cooking cup 3, ensuring that the ingredients can fall smoothly into the cutting area.

[0047] Compared to existing technologies that require separate purchases of different machines and have limited functionality, this solution integrates slicing, shredding, and dicing functions into a single device and utilizes replaceable modular blade components, significantly reducing the space occupied by the device and substantially lowering the user's procurement costs.

[0048] Specifically, in this embodiment, the mesh cutter 52 has a carrier plate 521 and blades arranged in a crisscross pattern on the carrier plate 521. The cutting edge 531 of the blade is positioned toward the pressing part 532 of the cross-cutting blade 53 to ensure that the sliced ​​food cut from above can be effectively pressed through the blade by the pressing part 532.

[0049] The second cutter head 51 is provided with mounting holes 510, and the carrier plate 521 is detachably installed into the mounting holes 510 through a snap-fit ​​and slot structure. This structure allows users to quickly disassemble the cutter 52 without using tools when cleaning or replacing it, simply by pressing or slightly rotating it, which greatly improves the convenience of later maintenance of the product.

[0050] Specifically, in this embodiment, the shape and structure of the pressing component 62 are adapted to the pressing cylinder, thereby ensuring that the pressing component 62 has good guiding properties when sliding in the feeding cylinder 61 and is not easily deviated.

[0051] The pressing component 62 is cup-shaped, and the bottom of the pressing component 62 is provided with multiple flexible protrusions 621 for contacting the material, which can effectively increase the friction with the surface of the food and prevent the food from sliding and getting stuck in the pressing cylinder.

[0052] Meanwhile, a flexible protective ring 622 is provided on the top of the pressure component 62. The protective ring 622 is made of silicone, while the pressure component 62 is made of rigid plastic. The protective ring 622 is fitted onto or separately injection molded onto the top of the pressure component 62. This structure can effectively prevent the pressure component 62 from hardly colliding with the edge of the feed cylinder 61 during the insertion and withdrawal movement, and also plays a role in sealing and dust prevention, extending the service life of the feed assembly 6.

[0053] In this embodiment, a rotary locking mechanism is provided between the second cutter assembly 5 and the cover 2. When the user places the second cutter assembly 5 into the cover 2 and rotates it around its own axis by a preset angle under the action of external force, the rotary locking mechanism can pass the locking peak position to achieve a firm and fixed connection between the second cutter assembly 5 and the cover 2.

[0054] Specifically, the rotary locking mechanism includes a guide bar 511 and a stop protrusion 512 disposed on the outer periphery of the second cutter head 51, and a guide rail 21 and a stop groove 22 disposed on the inner side wall of the cover body 2; the guide bar 511 extends circumferentially along the second cutter head 51, and the stop protrusion 512 extends radially and circumferentially along the second cutter head 51.

[0055] In actual operation, when the second cutter head 51 rotates, the guide bar 511 moves along the guide rail 21, and at the same time, the stop cam 512 slides smoothly under the guidance of the guide rail 21 and the arc-shaped guide part 221 and finally enters the stop cam groove 22, thereby realizing the fixed engagement between the second cutter assembly 5 and the cover 2.

[0056] The stop groove 22 has an arc-shaped guide part 221 on one side to guide the stop protrusion 512 to enter smoothly, which can effectively reduce the alignment resistance.

[0057] Compared to existing technologies that rely on strong pressing and buckling or single groove fixation, this solution uses guide strip 511 and stop protrusion 512 to guide rail 21 and stop groove 22 to achieve rotational overrun locking. No large vertical pressing force is required during installation and disassembly, and the locking state after overrun is evenly stressed. Even under high-speed rotation, it can still maintain a stable connection between the cutter and the cover 2, effectively avoiding problems such as loosening and wobble of the cutter head.

[0058] Specifically, in this embodiment, a dedicated limiting mechanism is provided to enhance the stability and safety of the internal structure of the second tool assembly 5.

[0059] The limiting mechanism includes a protective plate 513 rotatably mounted on the second cutter head 51 and a stop rib 514 mounted on the second cutter head 51. The protective plate 513 has a U-shaped portion, and the inner wall of the U-shaped portion near its rotation axis is provided with an elastic locking protrusion 515.

[0060] The second tool assembly 5 also includes a guard ring 54 surrounding the outer periphery of the cross-cutting blade 53, which is used for alignment and assembly with the second cutter head 51.

[0061] During assembly, the operator places the cutter guard ring 54 into the second cutter disc 51, and then manually rotates the protective plate 513. Utilizing the deformation characteristics of the elastic locking protrusion 515, it is made to pass over the stop rib 514 and enter the locking position, thereby achieving effective axial limiting and fixing of the cutter guard ring 54 and the second cutter disc 51, preventing the cross-cutting blade 53 from detaching from the cutter disc under high-speed centrifugal force and causing a safety accident.

[0062] Compared to existing technologies that rely solely on bolts or single springs to fix the blade assembly, this solution utilizes a U-shaped plate to provide full coverage protection for the cross-cutting blade 53, while incorporating an elastic over-locking design. This allows for rapid locking and withstands significant axial pull-out forces, greatly enhancing the safety factor.

[0063] In this embodiment, in order to achieve dynamic adaptation of speed during food processing, the food processor is also equipped with a speed control unit 7; and the main unit 1 has a head shell 11 and a drive motor 12 located inside the head shell 11.

[0064] Specifically, the speed control unit 7 includes a knob unit 71 rotatably mounted on the head housing 11 and a voltage adjustment module that works in conjunction with the knob unit 71. The voltage adjustment module includes a potentiometer 721, which has an arc-shaped resistive element and a conductive contact that slides along the arc-shaped resistive element (for detailed specifications, please refer to the utility model patent with authorization publication number CN224112548U, entitled "A Food Processor with Stepless Speed ​​Adjustment Function").

[0065] In actual use, the user only needs to rotate the knob unit 71 back and forth to drive the conductive contact to slide along the surface of the resistive body. By continuously changing the resistance value, the voltage of the input drive motor 12 can be adjusted, thereby achieving stepless and smooth adjustment of the output speed of the drive motor 12.

[0066] Compared to existing technologies that rely solely on fixed 2-3 speed settings via mechanical toggle switches, this solution utilizes the linear sliding adjustment of potentiometer 721 to achieve a smooth speed adjustment process. This allows the solution to adapt to the different cutting needs of various ingredients, from soft fruits to hard root vegetables, providing a more refined processing control experience.

[0067] In this embodiment, a reduction gear module 8 is also included in order to convert the high-speed rotation of the motor into a torque output suitable for cutting.

[0068] The reduction gear module 8 is detachably mounted on the cover 2 via bolts and a cup-shaped housing 24. Specifically, it includes a first drive shaft 81, a first gear 82 located at the output end of the first drive shaft 81, a second gear 83 meshing with the first gear 82, a third gear 84 meshing with the second gear 83, and a second drive shaft 85 located at the output end of the third gear 84.

[0069] To achieve the effect of speed reduction and torque increase, the diameter of the first gear 82 is smaller than the diameter of the third gear 84, and also smaller than the diameter of the second gear 83. The diameter of the second gear 83 is equal to the diameter of the third gear 84.

[0070] Both the first transmission component 44 and the second transmission component 55 have irregularly shaped splined shafts. The second transmission shaft 85 is a transmission sleeve with an internal splined structure adapted to the irregularly shaped splined shaft, so that the second transmission shaft 85 can be quickly inserted and removed to cooperate with the first transmission component 44 or the second transmission component 55 to achieve stable torque transmission.

[0071] Specifically, to achieve safe engagement and power connection between the main unit 1 and the cover 2, the cover 2 is provided with a concave receiving groove 23, and a bowl-shaped housing 24 is provided inside the receiving groove 23. The reduction gear module 8 is fixedly installed in the receiving groove 23 by bolts and the bowl-shaped housing 24. A first through hole 241 is provided at the bottom of the bowl-shaped housing 24, and the first drive shaft 81 of the reduction gear module 8 extends upward from the first through hole 241 and is exposed to the outside.

[0072] The lower end of the head shell 11 of the main unit 1 has a fitting part 111 that matches the shape of the bowl-shaped shell 24. Inside the main unit 1, the transmission cylinder 14 at the power output end of the drive motor 12 is provided with a first elastic element 15 and a contact element 16.

[0073] In addition, the cover 2 is provided with a second through hole 25, and the tops of the first transmission member 44 and the second transmission member 55 are both fitted with irregular spline shafts 66; the free end of the irregular spline shaft 66 passes through the second through hole 25 and engages with the second transmission shaft 85 of the reduction gear module 8 to enable the first transmission member 44 or the second transmission member 55 to drive the second transmission shaft 85.

[0074] During the actual assembly process, when the fitting part 111 of the main component 1 has not yet been pressed and locked with the bowl-shaped housing 24, the first elastic element 15 drives the abutment element 16 to push the first transmission shaft 81 outward, so that it is disengaged from the spline meshing surface in the transmission cylinder 14. At this time, the power transmission between the main component 1 and the reduction gear module 8 is completely disconnected. When the user presses the fitting part 111 of the main unit 1 down into place along the bowl-shaped housing 24, the first drive shaft 81 overcomes the resistance of the first elastic element 15 and is pushed into the drive cylinder 14, establishing a stable internal spline engagement, thereby realizing the conduction of power. This design effectively avoids the risk of tool flying off due to accidental activation when the main unit 1 is not installed in place.

[0075] Specifically, the head housing 11 is also provided with a micro switch 17 electrically connected to the drive motor 12, and a pressing part 18 is movably provided on the top of the head housing 11; in terms of operation logic, the micro switch 17 and the voltage regulation module are electrically connected to the control circuit of the drive motor 12, and the two are in series in terms of circuit logic.

[0076] The voltage regulation module is mainly used to continuously adjust the voltage input to the drive motor 12 according to the rotation angle of the knob unit 71; while the micro switch 17 serves as the physical on / off control switch for the total power supply of the drive motor 12 circuit.

[0077] In actual use, the user can only press down the pressing part 18 to trigger the micro switch 17 to close and turn on the power of the drive motor 12 when the first drive shaft 81 and the drive cylinder 14 are engaged in the transmission after being pressed into place.

[0078] Compared to existing technologies that connect the switch directly in series with the motor circuit, this solution uses a micro switch 17 linked to the pressing position to establish a three-level linkage control mechanism of "mechanical locking to prevent mistake-proofing - physical switch start / stop - stepless speed regulation of the circuit". This effectively prevents the machine from starting accidentally when it is not installed in place, ensuring processing safety and eliminating safety risks.

[0079] Specifically, in this embodiment, the slicing blade 43 is mounted on the first cutting disc 41 via an interference fit between a locking hole and a locking post. The first cutting disc 41 has a discharge hole 45 near the slicing blade 43 for the passage of sliced ​​material. The discharge hole 45 communicates with the receiving cavity 31 of the food preparation cup 3. This discharge hole 45 corresponds to the cutting trajectory of the slicing blade 43, ensuring that the food, after being sliced ​​by the slicing blade 43, falls directly into the receiving cavity 31 without accumulating.

[0080] Specifically, in this embodiment, in order to achieve quick assembly and disassembly and stable transmission between the first cutter head 41 and the power output end, a detachable rotary engagement structure is provided between the middle part of the first cutter head 41 and the first transmission component 44.

[0081] The top end of the first transmission component 44 is provided with a spline hole 441, the lower end of the irregular spline shaft 66 is a pentagonal shaft body inserted into the spline hole 441, and the upper end of the irregular spline shaft 66 is a plum blossom-shaped shaft body inserted into the inner spline hole of the second transmission shaft 85.

[0082] The rotary engagement structure includes a plurality of wedge-shaped hooks 442 protruding from the outer periphery of the top of the first transmission member 44. The wedge-shaped hooks 442 are distributed circumferentially along the first transmission member 44. The main body of each wedge-shaped hook 442 protrudes radially outward. The top end face of the wedge-shaped hook 442 is provided with an inclined guide surface or a stepped guide slope. The bottom of the wedge-shaped hook 442 is provided with a support plane that cooperates with the first cutter head 41 and an anti-retraction locking position.

[0083] Correspondingly, the rotary engagement structure also includes a central mounting hole 443 in the middle of the first cutter head 41 for the top of the first transmission member 44 to pass through. The inner wall of the central mounting hole 443 is provided with a sliding groove 4431 and an inclined locking protrusion 445 that correspond one-to-one with the number and position of the wedge-shaped hooks 442. The opening size of the sliding groove 4431 is adapted to the contour of the wedge-shaped hooks 442 so that they can be inserted without interference. The inclined locking protrusion 445 extends circumferentially along the central mounting hole 443, and a smooth sliding guide surface is provided at the junction of the sliding groove 4431 and the inclined locking protrusion 445.

[0084] During actual installation, the user first inserts the top of the first transmission component 44 into the center mounting hole 443 of the first cutter head 41, and aligns each wedge-shaped hook 442 accurately with the slide groove 4431. Then, the user operates the first transmission component 44 to rotate relative to the first cutter head 41 around its own axis. The wedge-shaped hooks 442 will slide into the slide groove 4431 along the sliding guide surface. During the radial rotation and axial sliding process, the wedge-shaped hooks 442 pass the locking peak position along the sliding guide surface, so that the support plane of the wedge-shaped hooks 442 is tightly fitted with the side wall of the inclined protrusion 445. At the same time, the anti-retraction locking position on the wedge-shaped hooks 442 abuts against the top wall of the inclined protrusion 445, preventing it from retracting in the opposite direction.

[0085] Compared to the existing technology that relies solely on simple rivets or bolts to fix the first cutter head 41, this solution uses a wedge-shaped hook 442 and an inclined hook 445 to work together to achieve tool-free "insertion and rotation" quick loading and unloading. Furthermore, the wedge-shaped structure has a strong self-locking force after being locked in place, which can resist the torque generated by high-speed cutting.

[0086] Specifically, in this embodiment, in terms of the power transmission path, the top end of the first transmission member 44 is provided with an inner spline hole 441, and the inner spline hole 441 is equipped with a non-circular spline shaft 66; the end of the second transmission shaft 85 in the reduction gear module 8 is provided with an inner spline that is adapted to the non-circular spline shaft, thereby establishing an anti-slip meshing transmission fit between the two, so that the power can be smoothly transmitted to the first transmission member 44.

[0087] Meanwhile, to ensure sufficient radial and axial stability of the first transmission component 44 during high-speed rotation, a protruding limiting post 32 is detachably fixed to the bottom of the cooking cup 3 by bolts. The top surface of the limiting post 32 is smoothed. In actual use, a rolling bearing structure can also be added to it.

[0088] The bottom center of the first transmission component 44 has a slot 446 that matches the outer diameter of the limiting post 32. During assembly, the slot 446 at the bottom of the first transmission component 44 is directly fitted onto the limiting post 32.

[0089] In actual operation, the motor drives the reduction gear module 8 to rotate the second transmission shaft 85. The second transmission shaft 85 drives the first transmission component 44 to rotate through the meshing of the internal and external splines. The first transmission component 44 then drives the first cutter head 41 to perform high-speed cutting operations through the aforementioned rotational engagement structure. The limiting post 32 serves as a rotation axis support for the bottom of the first transmission component 44, allowing the first transmission component 44 to rotate stably around the central axis of the limiting post 32. This effectively reduces the radial runout generated during the transmission engagement process and significantly improves the transmission stability and service life of the entire machine.

[0090] Specifically, to improve the stability and anti-slip performance of the food processor 3 when placed on the table, the bottom of the food processor 3 is fitted with an anti-slip pad 33. The anti-slip pad 33 is made of silicone, which can effectively absorb the slight vibration during the operation of the motor and prevent the main unit from shifting on the table due to vibration.

[0091] In this embodiment, the feed cylinder 61 is offset at the central axis of the food preparation cup 3, so that the food can fall into the cutting area on one side of the mesh blade 52 under the action of gravity. This eccentric structure, together with the offset second drive shaft 85, makes the whole machine structure more compact, which not only optimizes the appearance, but also frees up the central area for the arrangement of electronic components.

[0092] Specifically, the cross-cutting blade 53 has a cutting edge 531 that extends upward at an angle away from the mesh blade 52 and a pressing part 532 that extends downward at an angle close to the mesh blade 52. When the main unit assembly 1 drives the cross-cutting blade 53 to rotate, the cutting edge 531 uses the cutting force of high-speed rotation to cut the material into flakes, and drives the pressing part 532 to force the flakes of material cut by the cutting edge 531 through the mesh blade 52, finally forming regular and uniform diced material that falls into the receiving cavity 31 of the cooking cup 3.

[0093] In this embodiment, the first blade disc 41 is provided with a plurality of balance holes 411, which are distributed on both sides of the slicing blade 43. Because the slicing blade 43 is a heavy metal blade protruding on one side, the blade disc will generate centrifugal unbalanced force when rotating at high speed. The design of the balance holes 411 reduces the structural weight on the opposite side on the one hand, and adjusts the overall center of gravity position on the other hand, so as to balance the center of gravity of the first blade disc 41.

[0094] Preferably, the slicing blade 42 has multiple slicing holes formed by stamping and stretching. The multiple slicing holes are divided into multiple groups, and each group of slicing holes is arranged along the radial direction of the first cutter disc 41. Each row includes 3-5 slicing holes. Multiple rows of slicing holes are arranged circumferentially around the first cutter disc 41. The cross-section of the slicing holes is lens-shaped or elongated elliptical.

[0095] This stamping and stretching combined with staggered cutting hole design ensures that the cutting resistance is evenly distributed and can continuously cut the food into uniform shreds, greatly improving the efficiency of the shredding operation.

[0096] Specifically, in this embodiment, a limiting mechanism is also included; the limiting mechanism includes a protective plate 513 and a stop rib 514 rotatably disposed on the second cutter head 51. The protective plate 513 has a U-shaped portion, and an elastic locking protrusion 515 is provided on the inner side wall of one end of the U-shaped portion near its rotation axis. The second cutter assembly 5 also includes a cutter guard ring 54 fixedly connected to the outer periphery of the cross-cutting blade 53. The cutter guard ring 54 is used for alignment and assembly with the second cutter head 51. When the cutter guard ring 54 is disposed in the second cutter head 51, the protective plate 513 is rotated to allow the elastic locking protrusion 515 to pass over the stop rib 514 and enter the locking position, so that the cutter guard ring 54 is axially limited and fixed with the second cutter head 51.

[0097] The design utilizes a spring-loaded locking structure similar to a snap-fit, which ensures the stability of the blade guard ring 54 and the cross-cutting blade 53 assembly during high-speed rotation, while eliminating the need for screw fastening and facilitating disassembly and cleaning.

[0098] The following describes the usage process of the present invention in conjunction with specific embodiments: When the user needs to use the first cutting tool assembly 4 to perform slicing or cutting operations, firstly, the wedge-shaped hook 442 at the top of the first transmission member 44 is aligned with the groove of the central mounting hole 443 of the first cutter disc 41 and inserted. Then, it is rotated relative to the first cutter disc 41 so that the wedge-shaped hook 442 passes over the locking peak position along the sliding guide surface of the inclined protrusion 445 and fits tightly and is locked, thereby completing the quick locking of the first transmission member 44 and the first cutter disc 41. Next, align the bowl-shaped housing 24 on the cover 2 with the fitting part 111 of the main unit 1 and press it down to establish the meshing engagement between the first drive shaft 81 and the drive cylinder 14. Place the ingredients into the feed cylinder 61 and use the pressing component 62 to press them down; When the speed control unit 7 is activated, the drive motor 12 drives the second transmission shaft 85 to rotate through the offset reduction gear module 8. The second transmission shaft 85 drives the first transmission component 44 and the first blade 41 to rotate at high speed. In actual use, when assembling the first transmission component 44 and the first blade 41, they can be installed in the forward or reverse direction, so that the shredding blade 42 of the first blade 41 faces upward to correspond to the food or the slicing blade 43 of the first blade 41 faces upward to correspond to the food; thereby performing the corresponding shredding or slicing action, and the processed food falls directly into the receiving cavity 31 of the food preparation cup 3.

[0099] When the user needs to use the second cutter assembly 5 for dicing, first place the cutter guard ring 54 into the second cutter disc 51, rotate the protective plate 513 so that the elastic locking protrusion 515 of the U-shaped part of the protective plate 513 passes over the stop rib 514 and enters the locking position, thus completing the axial limiting assembly of the cutter guard ring 54 and the second cutter disc 51. Then, the guide bar 511 of the second cutter head 51 is aligned with the guide rail 21 on the inner side wall of the cover body 2, and the stop protrusion 512 slides and rotates along the guide rail 21 so that it passes over the arc-shaped guide part 221 and enters the stop groove 22, thereby realizing the rotational locking and fixing of the second cutter head 51 and the cover body 2. Similarly, align the main unit 1 with the bowl-shaped housing 24 and press it into place to enable power transmission. Place the ingredients to be diced into the feeding cylinder 61 and press them down with the pressing component 62; The speed control unit 7 is started and adjusted to a suitable speed. The drive motor 12 drives the second transmission shaft 85 to drive the cross-cutting blade 53 to rotate at high speed through the second transmission component 55. The cutting edge 531 of the cross-cutting blade 53 first cuts the food into slices. Then the pressing part 532 forces the sliced ​​material downward through the mesh of the mesh blade 52, and finally cuts it into uniform diced pieces that fall into the receiving cavity 31 of the cooking cup 3.
