Technical Field
[0001] This utility model relates to the field of food processor technology, and in particular discloses a food processor head that facilitates cord retraction. Background Technology
[0002] Currently, with the improvement of living standards, food processors are being used more and more widely in home kitchens. Traditional food processor heads have some shortcomings in their structural design, such as inconvenient power cord storage, which can easily lead to kitchen clutter and pose safety hazards during use. At the same time, issues such as imprecise speed control, inadequate safety features, and low transmission efficiency also affect the user experience and performance of food processors. Therefore, developing a food processor head with easy cord retraction, high safety performance, precise speed control, and high transmission efficiency is of great significance. Utility Model Content
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a food processor head that is easy to reel in the cord.
[0004] To achieve the above objectives, this utility model provides a food processor head that facilitates cord retraction, comprising a head assembly. The head assembly includes a body, a rotating shaft disposed within the body, a drive component for rotating the shaft, a power cord electrically connected to the drive component, and a switch assembly. It also includes a cord retractor disposed on the body, the outer side of which is used to wind the power cord, and the cord retractor is used to limit the free end of the power cord wound on the outer side of the body. The power cord is used to connect the drive component to an external power source, and the switch assembly is used to adjust the on / off state of the circuit of the drive component after power connection, thereby controlling the rotation or stopping of the rotating shaft. The rotating shaft is used to connect to external food processing blades.
[0005] Furthermore, the take-up member has two elastically arranged clamping arms, which are spaced apart, and the space between the two clamping arms is used to accommodate the power cord.
[0006] Furthermore, the take-up component also includes a mounting component that cooperates with the two clamping arms, and the mounting component is detachably connected to the body.
[0007] Furthermore, the mounting component is arranged in a circular shape, and the circular mounting component is rotatably positioned at the end of the machine body away from the rotating shaft.
[0008] Furthermore, the free end of the clamping arm has a guide slope, which is located on the side where the two clamping arms are close to each other. The guide slopes of the two clamping arms form a V-shaped guide groove, which is used to guide the power line through the V-shaped guide groove into the space between the two clamping arms.
[0009] Furthermore, the head assembly also includes a knob that works in conjunction with the switch assembly. The knob is rotatably mounted on the body, and a potentiometer is connected to the knob to convert the rotation angle of the knob into a resistance value. The body contains a main control board unit that electrically interacts with the potentiometer and the drive component. When the knob is rotated, the resistance change signal of the potentiometer is transmitted to the main control board unit. The main control board unit adjusts the input voltage of the drive component based on the resistance change signal, thereby adjusting the rotational speed of the shaft.
[0010] Furthermore, the switch assembly includes a press cover that reciprocates relative to the body and a first micro switch disposed on the press cover. The first micro switch is electrically connected to the drive unit via a main control board unit. When the press cover is subjected to external force, it abuts against the contact of the first micro switch. The main control board unit controls the start or stop of the drive unit according to the trigger signal of the first micro switch.
[0011] Furthermore, the body and the press cover have a second elastic element for driving the press cover to reset; the press cover is provided with a guide post, and the switch assembly also includes a guide sleeve disposed on the body for accommodating the guide post, and the second elastic element is sleeved on the outside of the guide sleeve and the guide post.
[0012] Furthermore, the machine body is equipped with a linkage component that can reciprocate elastically, and a second micro switch that cooperates with the linkage component is set on the machine body. After the machine body is correctly installed on the cooking container, the cooking container drives the linkage component to move forward and contact the contact of the second micro switch to conduct the power supply circuit of the driving component. When the machine body is detached from the cooking container or is not correctly installed, the linkage component does not contact the contact of the second micro switch, so the power supply circuit of the driving component is not conducted.
[0013] Furthermore, the linkage is reciprocatingly disposed within the machine body, and a first elastic element for driving the linkage to reset is provided between the machine body and the linkage. One end of the linkage is used to abut against the cooking container, and the other end of the linkage is used to abut against the contact of the second micro switch.
[0014] The beneficial effects of this utility model are: (1) The food processor head achieves quick storage and fixation of the power cord through a combination of flexible clamping arms and guide bevels. Users only need to push the free end of the power cord along the V-shaped guide groove, and the flexible clamping arms will automatically clamp the cord, avoiding the problem of power cords from scattering or tangling as in traditional food processors. At the same time, the design of the plug's outer diameter being larger than the wire gap can effectively prevent the power cord from accidentally falling off, ensuring safety during use. This cord storage structure requires no additional tools or complicated operations, significantly improving the efficiency of users in storing power cords, especially suitable for kitchens with limited space, keeping the countertop neat and tidy. In addition, the design of the flexible clamping arms allows users to adjust the length of the power cord as needed, providing greater flexibility and further optimizing the user experience.
[0015] (2) The food processor head features a triple safety protection system through the coordinated design of linkage components, micro switches, and the trigger shaft of the switch assembly. First, the mechanical linkage between the linkage components and the food processing container ensures that the head cannot be started if it is not installed correctly, avoiding safety hazards caused by misoperation. Second, when the switch assembly is closed, the trigger shaft must be pressed to conduct the drive circuit, preventing accidental start-up in an incompletely closed state. Third, the design of the sliding hole of the rotating shaft and the non-circular part of the food processing blade ensures that the blade cannot be driven if it is not inserted correctly, further improving operational safety. These interlocking mechanisms not only meet the safety standards for food processing equipment but also avoid the potential failure risks of the electronic control system through the reliability of the physical structure, providing users with double protection. In addition, the design of the elastic reset component allows each interlocking component to automatically return to its original position after use, maintaining the long-term stability of the equipment.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0019] Please see Figures 1 to 7 As shown, this utility model discloses a food processor head for easy cord retraction, comprising a head assembly 1. The head assembly 1 has a body 2, a rotating shaft 4 disposed within the body 2, a drive component 5 for driving the rotating shaft 4 to rotate, a power cord 6 electrically connected to the drive component 5, and a switch assembly 3. It also includes a cord retractor 7 disposed on the body 2, the outside of the body 2 for winding the power cord 6, and the cord retractor 7 for limiting the free end of the power cord 6 wound on the outside of the body 2. The power cord 6 is used to connect the drive component 5 to an external power source, and the switch assembly 3 is used to adjust the on / off state of the circuit of the drive component 5 after connecting to the power source, thereby controlling the rotation or stopping of the rotating shaft 4. The rotating shaft 4 is used to connect to an external food processing blade 9.
[0020] Specifically, the take-up member 7 has two elastically arranged clamping arms 11, which are spaced apart, and the space between the two clamping arms 11 is used to accommodate the power cord 6.
[0021] Specifically, the take-up member 7 also includes a mounting member 13 that cooperates with the two clamping arms 11, and the mounting member 13 is detachably connected to the body 2.
[0022] Specifically, the mounting component 13 is arranged in a circular shape, and the circular mounting component 13 is rotatably positioned at the end of the machine body 2 away from the rotating shaft 4. In actual use, the position of the clamping arm 11 can be adjusted by rotating the mounting component 13 according to the length of the power cord 6, thereby accommodating the storage of power cords 6 of different lengths.
[0023] Specifically, the mounting component 13 can be detachably connected to the clamping arm 11 via a snap-fit structure, so that if the clamping arm 11 breaks unexpectedly, it can be replaced or repaired.
[0024] Specifically, the mounting component 13 can be slidably set along the length of the body 2 via a slider rail structure, further improving the adaptability of the take-up component 7.
[0025] In actual use, the food processor head achieves quick storage and fixation of the power cord 6 through the design of the elastic clamping arm 11 and guide slope 110 of the cord take-up piece 7 (when not in use, the power cord 6 can be quickly stored by spirally winding it around the outer circumference of the body 2 and inserting its end between the two clamping arms 11).
[0026] Specifically, the free end of the clamping arm 11 has a guide slope, which is located on the side where the two clamping arms 11 are close to each other. The guide slopes of the two clamping arms 11 form a V-shaped guide groove. The guide slope is used to guide the wire of the power line 6 through the V-shaped guide groove into the wire-carrying gap 12 formed by the two clamping arms 11.
[0027] In practical use, the V-shaped guide groove formed by the two guide ramps automatically centers the cable through geometric constraints as it guides the cable into the cable holding gap 12. When the cable contacts the V-shaped guide groove, the symmetrical guiding force of the ramps on both sides forces the cable to slide along the center line, ensuring that it enters the cable holding gap 12 perpendicularly, avoiding insecure clamping or cable damage caused by skewness or offset. This design is particularly important for stiffer or thicker power cables 6, effectively solving the problem of difficult alignment due to the high rigidity of the cable in traditional cable take-up devices. At the same time, the convergence structure of the V-shaped guide groove applies a progressive clamping force to the cable during the take-up process, allowing the elastic clamping arm 11 to fine-tune the position of the cable before closing, ensuring that the cable and the cable holding gap 12 are completely coaxial in the final clamping state, thereby maximizing clamping stability and reducing the risk of accidental loosening caused by cable offset.
[0028] Specifically, an arc-shaped segment 111 is formed between the two clamping arms 11. In this embodiment, the arc-shaped segment 111 is bent into a U-shape (i.e., forming a U-shaped groove that communicates with the V-shaped guide groove). Combined with the material design of the clamping arms 11, this design can minimize the damage to the power cord 6 caused by the clamping arms 11.
[0029] In this embodiment, the clamping arm 11 and the mounting component 13 are integrally molded from silicone material. The clamping arm 11 can adapt to power cords 6 of different diameters by utilizing the elastic force of the silicone material itself. The V-shaped guide groove guides the cord to accurately enter the wire-holding gap 12. Combined with the anti-detachment design where the outer diameter of the connector is larger than the wire-holding gap 12, it ensures that the power cord 6 is not easily loosened during use and will not accidentally fall off due to gravity or external force during storage. This structure eliminates the need for manual winding or clipping, allowing for the release and restraint of the cord with just one hand, making it particularly suitable for high-frequency use scenarios in the kitchen.
[0030] The flexible clamping arm 11 of the cord retractor 7 features a deformable design. Through dynamic adjustment of the cable clearance 13, it can adapt to power cords 6 of different diameters, ensuring uniform clamping force without damaging the cord. Users simply push the free end of the power cord 6 between the two arms along the guide slope 110, and the clamping arm 11 automatically clamps the cord using its own tension, eliminating the need for manual winding or clipping. This design not only simplifies the storage process but also allows for one-handed operation, making it particularly suitable for high-frequency kitchen use. When releasing the power cord 6, simply pull the connector outwards, and the flexible arm will naturally expand, avoiding the problems of cable jamming or deformation caused by long-term use in traditional cord retractors. Furthermore, the material selection for the flexible clamping arm 11 balances flexibility and wear resistance, ensuring stable clamping performance even after repeated opening and closing.
[0031] In addition, during actual production, the cord retractor 7 can be installed on the body 2 or the knob 21. The installation position can be flexibly selected according to the user's habits, effectively avoiding the power cord 6 from getting tangled with the cooking container and the work surface, keeping the kitchen environment clean, and improving the portability and aesthetics of the equipment.
[0032] Specifically, the upper surface of the body 2 is provided with a knob 21 that is linked to the switch assembly 3. The knob 21, by rotating, drives a potentiometer 210 (rotary variable resistor) integrated within it. The main control board unit 22 adjusts the input voltage of the drive component 5 in real time according to the change in resistance value, thereby achieving stepless speed regulation of the rotating shaft 4 (speed range, such as 500-15000 r / min). The pressing cover 30 of the switch assembly 3 is designed in combination with the first micro switch 301. The pressing cover 30 achieves linear reciprocating motion through the guide sleeve 32 and the guide post 31, and automatically resets under the action of the second elastic element (compression spring in this embodiment). When the user presses the pressing cover 30, the guide post 31 inside it contacts the contact of the first micro switch 301, and the main control board unit 22 accordingly turns the power supply circuit of the drive component 5 on or off.
[0033] Compared with traditional mechanical gear switches, the speed adjustment function of knob 21 has higher speed adjustment accuracy and no contact wear; the combination of push-button switch and reset elasticity avoids the jamming problem caused by frequent pressing of traditional mechanical switches.
[0034] Specifically, the bottom of the machine body 2 is equipped with a sliding linkage 24, whose first elastic element (such as a spring) pushes the linkage 24 to the default position (untriggered state). When the machine head assembly 1 is correctly installed on the cooking container 8, the edge of the container pushes the linkage 24 to slide into the machine body 2, and the other end of the linkage 24 triggers the second micro switch 240 to conduct the circuit. If the machine head is not securely installed or detaches from the container, the linkage 24 retracts under the action of the first elastic element, disconnecting the circuit and preventing the drive unit 5 from starting. This structure works logically with the main control board unit 22 to ensure that the equipment only operates in the usage state.
[0035] The combination of the linkage and the micro switch eliminates the risk of tool idling caused by accidental switch activation, significantly improving safety; the reset design of the elastic element prevents the mechanism from jamming.
[0036] The free end of the power cord 6 has a connector 14 located outside the two clamping arms 11, and a flexible member 15 connected to the connector 14 and the free end of the power cord. The outer diameter of the flexible member 15 is larger than the wire-carrying gap 12. In actual use, the two clamping arms 11 can be designed with an adjustable gap. For example, the tightening force of the bolts can be used to bring the two clamping arms 11 closer to each other, so that the wire-carrying gap 12 can be adapted to flexible members 15 with different outer diameters, thereby improving the adaptability of the take-up member 7.
[0037] Specifically, the head assembly 1 also includes a knob 21 movably mounted on the switch assembly 3, a potentiometer for transmitting the resistance signal of the knob 21, and a main control board unit 22 disposed inside the body 2 and connected to the potentiometer and the drive component 5. The knob 21 is connected to the potentiometer and is used to adjust the rotation speed of the shaft 4. Rotating the knob 21 inputs a signal to the main control board unit 22 via the potentiometer. After receiving the signal, the main control board unit 22 changes the resistance. The change in resistance causes the voltage of the drive component 5 to change, thereby changing the rotation speed of the shaft 4.
[0038] In actual use, this food processor achieves continuous adjustment of the rotation speed of the shaft 4 through the linkage design of knob 21 and potentiometer. Users simply rotate knob 21 on the switch assembly 3, and the potentiometer converts the rotation angle into a resistance signal, which is transmitted to the main control board unit 22. The main control board then dynamically adjusts the voltage of the drive component 5 to achieve linear changes in rotation speed. Compared to traditional fixed-gear designs, this stepless speed control mechanism can more accurately match the processing needs of different ingredients (such as low-speed kneading for fine meat paste and high-speed impact for ice crushing), significantly improving the cooking effect. At the same time, the analog signal transmission method of the potentiometer has the advantages of fast response and smooth adjustment compared to digital encoders, avoiding stuttering or speed jumps during gear switching, ensuring the stability and consistency of the food processing process. Furthermore, the integrated layout of knob 21 and switch assembly 3 creates a spatial linkage between the speed adjustment operation and the closing action of switch assembly 3, eliminating the need for users to look down for individual buttons and improving the continuity and convenience of operation.
[0039] In this embodiment, the drive component 5 is equipped with a speed sensor. The main control board unit 22 dynamically adjusts the voltage of the drive component 5 according to the real-time speed signal fed back by the speed sensor through a PID algorithm to realize closed-loop control of the rotational speed of the shaft 4.
[0040] In practical use, the newly added speed sensor and PID algorithm construct a closed-loop control system, which monitors the rotation speed of shaft 4 in real time and automatically compensates for speed deviations caused by load changes or voltage fluctuations. When the hardness of the ingredients increases during processing (such as when crushing ice) or the motor resistance increases, the system can dynamically increase the drive voltage through PID adjustment to ensure a constant speed; conversely, it automatically reduces the voltage under light loads to save energy and reduce noise. This adaptive control breaks through the limitations of traditional open-loop systems (which rely solely on potentiometer settings) and is especially suitable for high-load scenarios such as high-speed blenders, significantly improving the uniformity and efficiency of food processing. In addition, closed-loop control can effectively avoid the risk of overload burnout caused by motor stall, extending the service life of the equipment.
[0041] Specifically, the body 2 is provided with a linkage 24 that reciprocates elastically, and a second micro switch 240 that cooperates with the linkage 24 is provided on the body 2. After the body 2 is correctly installed on the cooking container 8, the cooking container 8 drives the linkage 24 to move forward and abut against the second micro switch 240 to conduct the power supply circuit of the driving component 5. When the cooking container 8 is detached or not installed correctly, the linkage 24 moves in the reverse direction to disconnect the power supply circuit of the driving component 5.
[0042] In actual use, this food processor utilizes a mechanical linkage design between the linkage component 24 and the second micro switch 240 to create a forced safety interlock system between the processor head and the food container 8. When the processor head is correctly installed on the container, the container protrusion drives the linkage component 24 to move forward against spring resistance, triggering the micro switch to activate the power supply circuit of the drive component 5, ensuring that the device can only be started when the container and processor head are fully connected. Conversely, if the processor head is not installed or is not installed properly, the linkage component 24 resets under the action of the spring, disconnecting the circuit and preventing safety hazards such as food splashing or the device running idle due to a missing or loose container. Compared with traditional electronic sensors, this physical rigid constraint mechanism has higher anti-interference capabilities, making it particularly suitable for humid and dusty kitchen environments, avoiding the risk of misjudgment caused by oil or moisture. In addition, the elastic reset design of the linkage component 24 allows it to automatically return to its original position after the container is removed, eliminating the need for manual operation and ensuring continuous and reliable operation of the device.
[0043] Specifically, the linkage 24 is slidably disposed inside the body 2, and there is a first elastic element between the body 2 and the linkage 24 for driving the linkage 24 to reset. Preferably, the first elastic element is a spring. The first elastic element is sleeved on the positioning part of the linkage 24. One end of the linkage 24 is used to abut against the cooking container, and the other end of the linkage 24 is used to abut against and trigger the second micro switch.
[0044] In practical use, the linkage 24 achieves an automatic reset function through the design of the first elastic element sleeved on the positioning part. When the cooking container is removed, the elastic element releases its stored energy, driving the linkage 24 to move in the opposite direction, disengaging it from the second micro switch 240 and ensuring the circuit is disconnected. This design avoids the reset failure problem caused by gravity or jamming in traditional mechanical interlocking devices, and is especially suitable for scenarios involving frequent container installation or removal. The preload of the elastic element has been optimized to ensure that the linkage 24 is smoothly compressed during container installation and quickly rebounds after unloading, preventing adhesion caused by residual food or oil. The cylindrical structure of the positioning part precisely matches the inner hole of the elastic element, allowing the linkage 24 to maintain a straight trajectory during reciprocating motion, avoiding twisting or breakage of the elastic element due to misalignment, and extending the service life of the component.
[0045] Specifically, the guiding structure of the guide post 31 and guide sleeve 32 not only limits the movement trajectory of the switch assembly 3, but also ensures through physical limiting that the trigger shaft 23 accurately presses the first micro switch 301 when the switch assembly 3 is fully closed. The depth design of the guide sleeve 32 matches the compression amount of the second elastic element, so that the switch assembly 3 maintains a stable preload in the closed state, avoiding loosening of the switch assembly 3 due to vibration. When the switch assembly 3 is not fully closed, the incomplete engagement of the guide sleeve 32 and guide post 31 will be fed back to the user's hand through the elasticity of the second elastic element, forming an operation prompt and preventing safety hazards caused by misjudging the closed state. In addition, the elastic reset design allows the switch assembly 3 to automatically maintain an angle of about 45° after opening, which not only facilitates the user's observation of the inside of the cooking container, but also prevents the switch assembly 3 from fully opening and hitting the countertop or other equipment.
[0046] Specifically, one end of the rotating shaft 4 is provided with a sliding hole 41, and a sliding sealing plate 42 and a third elastic element 43 are provided in the sliding hole 41. The sealing plate 42 is used to block the third elastic element 43. The sliding hole 41 is a non-circular hole. The cooking container is provided with a rotating cooking knife 9. The cooking knife 9 has a non-circular part. The non-circular part is used to press against the sealing plate 42 to compress the third elastic element 43 and insert it into the sliding hole 41.
[0047] In actual use, the sliding hole 41 of the rotating shaft 4 adopts a non-circular hole design, forming a uniquely matched mechanical interface with the non-circular part of the cooking knife 9, ensuring that only the dedicated knife can be correctly inserted and drive the rotating shaft 4 to rotate. When the knife is not fully inserted, the non-circular part cannot fully engage with the sliding hole 41. At this time, even if the switch assembly 3 is closed and the trigger circuit of the linkage 24 is turned on, the rotating shaft 4 still cannot rotate due to the lack of a transmission medium, avoiding the safety hazards caused by dry running or misoperation. Compared with traditional electronic identification methods, this physical structure's anti-misinsertion mechanism has higher reliability and anti-interference ability, and is especially suitable for multi-member scenarios in a home environment.
[0048] Furthermore, the precise fit between the sliding hole 41 and the non-circular part of the blade can transmit greater torque, meeting the demands of high-intensity operations such as blending, while reducing vibration and noise caused by gaps in the fit. Under normal conditions, the sealing plate 42 is pushed by the third elastic element 43 to block the opening of the sliding hole 41, effectively preventing foreign objects such as liquids and dust from entering the machine head, ensuring the cleanliness and safety of the drive component 5 and the circuit system. When the blade is inserted, the non-circular part abuts against the sealing plate 42, compressing the elastic element and causing the sealing plate 42 to retract into the sliding hole 41. At this time, the pre-tightening force of the elastic element still pushes the sealing plate 42 to adhere to the blade surface, forming a dynamic sealing barrier to prevent the liquid from leaking along the gap between the blade and the sliding hole 41.
[0049] This design overcomes the limitations of traditional open-structure rotating shafts, which are prone to leakage. It is especially suitable for making liquid ingredients such as juices and thick soups, avoiding short circuits or corrosion caused by liquid entering the motor. The sealing plate 42 is made of food-grade silicone, which is resistant to high temperatures and chemical corrosion, ensuring safety and reliability for long-term use.
[0050] In this embodiment, a plurality of evenly distributed conductive contact pieces are provided on the inner wall of the sliding hole 41, and conductive contacts are provided at the corresponding positions of the non-circular part of the cutting knife 9. When the non-circular part of the cutting knife 9 is inserted into the sliding hole 41, the conductive contacts and conductive contact pieces make contact and conduction, forming a detection circuit. The detection circuit is connected to the main control board unit 22, and the main control board unit 22 determines whether the knife is correctly installed based on the conduction status of the detection circuit.
[0051] In actual use, the detection circuit formed by the newly added conductive contact piece and conductive contact point can accurately determine whether the blade is correctly inserted into the sliding hole 41. Only when the non-circular part of the blade is fully and correctly inserted into the sliding hole 41, and the conductive contact point and conductive contact piece are in close contact to make the circuit conductive, will the main control board unit 22 allow the drive component 5 to start. This avoids dangerous situations such as the shaft 4 spinning freely, the blade shaking, or even flying out due to improper blade installation, such as partial insertion or angular deviation, greatly improving the safety of the food processor, especially suitable for high-speed rotating food processing scenarios.
