Moreover, the output speed range is wide and the torque is high, avoiding stalling caused by high processing resistance.

Description

Technical Field

[0001] This invention belongs to the field of kitchen appliances, and particularly relates to a cup body component for a multi-functional food processor and the food processor itself. Background Technology

[0002] Existing food processors require multiple sets of multi-functional cup components. By replacing different cup components with the main unit and inputting commands through the user interface, the control module controls the motor to output corresponding speeds, achieving different cooking functions such as mincing meat, chopping vegetables, and kneading dough. These multi-functional cup component sets are numerous and complex to install, taking up considerable space and hindering storage for users, while also incurring high costs. Furthermore, while current food processors can output multiple speeds, the speed adjustment range is mostly based on voltage regulation. This method results in a significant decrease in output torque, making it prone to stalling when processing hard or high-resistance materials, directly impacting the processing efficiency and quality of the multi-functional cup components. Material adaptability is poor, leading to unsatisfactory processing results. During multi-functional cooking, users also need to input the corresponding speed, and the program adjusts the speed and executes the program accordingly. This cumbersome program control reduces reliability and significantly impacts the user experience.

[0003] Patent application number 201911095314.3 discloses a high-speed and low-speed dual-output motor. It employs an internal coupling connected to the motor's output shaft for high-speed output, and an external coupling connected to a speed-changing mechanism for low-speed output. The upper planetary gear set and the external coupling in the speed-changing mechanism are movably configured to achieve high and low speed outputs via the internal and external couplings. This motor has two output speeds, which can be respectively coupled to a first mixing cup with a first blade assembly and a second mixing cup with a second blade assembly, thus achieving high-speed and low-speed cooking. While this structure achieves high and low speed outputs through a reduction gearbox, it requires matching different cup components, has multiple multi-functional accessories that are inconvenient to assemble, and occupies a large storage space. Furthermore, the speed-changing mechanism only reduces noise at high speeds; noise still occurs at low speeds due to the movably configured speed-changing mechanism.

[0004] The utility model patent with application number 201921569084.5, entitled "A Knife Assembly and a Food Processor with the Same," discloses a knife assembly with a detachable connection between the output shaft and the blades, facilitating the replacement of different blades. Furthermore, by adding a first bushing, it expands the connection methods to accommodate various blades. It allows for multi-functional food processing within a single cup by replacing the knife assembly. However, even when changing blades, it still only involves changing different blades at a uniform output speed, failing to expand to high-speed and low-speed cooking functions. The patent also discloses that the motor can be a variable-speed motor or a fixed-speed motor with a gearbox to output different speeds. This configuration increases motor cost and limits output torque, preventing the expansion to slow-speed, high-torque functions such as kneading and juicing. Additionally, there is a problem where users may encounter mismatches between the installed blades and the selected cooking function when assembling the multi-functional accessory, leading to processing failures. Summary of the Invention

[0005] The purpose of this invention is to provide a cup assembly for a food processor that is easy to operate, avoids user misoperation, occupies little space, has self-identification function, and is multi-functional, as well as a food processor.

[0006] To solve the above-mentioned technical problems, the present invention provides a cup body assembly for a food processing machine, including a cup body, a cup lid, and a processing component disposed in the cup body, and further including a gearbox. The gearbox includes a movably disposed clutch output shaft. When the clutch output shaft moves to a first position, it drives the processing component to output a first rotational speed. When the clutch output shaft moves to a second position, it drives the processing component to output a second rotational speed. The cup lid is installed in place, so that the clutch output shaft is held in the first position or the second position.

[0007] Furthermore, the cup lid axially limits the processing component, so that the clutch output shaft is in a first position or a second position to output a first speed or a second speed.

[0008] Furthermore, the processing components include a first processing component and a second processing component. The cup lid and the cup body are fitted in the same position. The first processing component axially limits the clutch output shaft in a first position, and the second processing component axially limits the clutch output shaft in a second position.

[0009] Furthermore, the cup lid is provided with a limiting part for limiting the movement of the processing component, and the processing component abuts against the limiting part and the clutch output shaft respectively.

[0010] Furthermore, the processing component includes a first processing component and a second processing component. The clutch output shaft is drivenly connected to the first processing component and outputs a first rotational speed. The clutch output shaft is drivenly connected to the second processing component and outputs a second rotational speed.

[0011] Furthermore, the gearbox includes a first limiting structure and a second limiting structure to limit the clutch output shaft when it moves to the first position and the second position, respectively.

[0012] Furthermore, the gearbox includes a first transmission mechanism and a second transmission mechanism, and the clutch output shaft is selectively connected to one of the first transmission mechanism and the second transmission mechanism. The first transmission mechanism includes a first planetary output shaft, a first planetary gear, and a first planetary carrier. The second transmission mechanism includes a second planetary output shaft, a second planetary gear, and a second planetary carrier. The first planetary output shaft is provided with the first limiting structure, and / or the second limiting structure includes a bearing disposed within the gearbox.

[0013] Furthermore, the first limiting structure includes a limiting end face, and the clutch output shaft includes a first transmission part and a second transmission part. When the clutch output shaft moves to the first position, the first transmission part abuts against the limiting end face for limiting. When the clutch output shaft moves to the second position, the second transmission part abuts against the bearing for limiting.

[0014] Furthermore, the processing component is provided with a positioning structure, and the processing component is installed in place and abuts against the clutch output shaft through the positioning structure.

[0015] Furthermore, the processing component is provided with a transmission hole that engages with the clutch output shaft, and the positioning structure includes the inner wall of the transmission hole, or the positioning structure includes a positioning ring, protrusion, groove, or step disposed in the transmission hole.

[0016] Furthermore, a food processing machine includes a main unit, a motor inside the main unit, and the aforementioned cup assembly; or, a food processing machine includes the aforementioned cup assembly, a cup lid that closes to the cup opening and a motor inside the cup lid.

[0017] The beneficial effects of this invention are: 1. This invention uses a clutch output shaft with first and second positions to drive the processing components. In the first position, the clutch output shaft outputs a first speed for a specific multi-functional cooking method. In the second position, it outputs a second speed for a different speed requirement. Automatic speed switching is achieved by changing the clutch output shaft's position. This mechanical speed switching ensures high reliability. The clutch output shaft has a wide output speed range and high torque, avoiding stalling due to high processing resistance, significantly improving the reliability and versatility of multi-functional cooking. It also occupies little space and has low cost. Furthermore, this design results in stable operation and low noise in the food processor, providing a good user experience. Users only need to install the components to trigger the clutch output shaft to move to the corresponding position and output the speed corresponding to the processing component. Automatic switching between different speeds is easily achieved through the clutch output shaft, eliminating the need for manual selection by the user, making operation convenient and providing a good user experience.

[0018] 2. During processing, the cup lid is installed in place, limiting and maintaining the clutch output shaft in a first position to stably output a first speed, or maintaining it in a second position to stably output a second speed. Different positions can be defined depending on the cup lid or different processing components, allowing specific speed outputs after the cup lid or a specific processing component is installed, thus performing specific processing functions. This setup eliminates the need for user selection; simply placing the required processing component or assembling the cup lid will automatically match the clutch output shaft to a specific position to output a specific speed, without human or program intervention. This simplifies the multi-functional control program, optimizes human-machine interaction, and mechanically selects or switches speeds, greatly improving overall machine reliability. Specifically, different processing components can be driven to output different speeds by installing the cup lid in the same position, or the same processing component can output different speeds after the cup lid is installed. In this case, the position of the clutch output shaft and the corresponding output speed can be adjusted by controlling the cup lid.

[0019] 3. The gearbox includes a first gear shift mechanism and a second gear shift mechanism, which are connected to drive each other to perform one-stage and two-stage gear shifting of the initial motor speed. After the machining component is installed, the clutch output shaft is fixed in either the first or second position. Thus, once the position of the clutch output shaft is determined, the speed is determined, and the machining function and attributes are accordingly determined. Users do not need to manually identify or adjust the speed rotation, ensuring accurate and quick operation. Furthermore, it completely eliminates the possibility of user error causing a mismatch between the placed machining component and the actual machining program or speed.

[0020] 4. The speed switching is achieved mechanically via the clutch output shaft, resulting in high torque and precise speed control. The installation and positioning of the processing components and the clutch output shaft are also simplified. The processing components are detachable and can be replaced with different components depending on the multi-functional processing type, making the structure simple and operation convenient. Furthermore, the clutch output shaft is limited to its first and second positions by a limiting structure within the reduction gearbox, ensuring precise movement and stable output speed. Mechanical wear and noise are minimized during the switching between the first and second positions. The cup lid intelligently and automatically selects the specific speed of the clutch output shaft through the processing components. After the processing components are in place and the cup lid is installed, the clutch output shaft is constrained by the cup lid to a specific first or second position that matches the attributes of the processing components. This ensures precise and error-free matching of function and speed, eliminating the risk of program errors or processing failures caused by incorrect component placement or incorrect function selection.

[0021] 5. A food processor with the aforementioned cup assembly can achieve a wide range of speeds, high torque, and diverse multi-functional cooking, such as mincing meat, beating eggs, kneading dough, shaving ice, and slow-speed juicing. It truly achieves multiple functions in one cup and features automatic speed recognition, avoiding user misoperation and improving product performance and user experience.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1 like Figures 1 to 9 As shown, this embodiment provides a gearbox, a cup assembly having the gearbox, and a food processing machine having the cup assembly.

[0040] like Figure 1 As shown, a gearbox 100 for a food processing machine includes a processing component 400 driven by a motor. The gearbox 100 includes a fixedly disposed first gear shift mechanism 101 and a second gear shift mechanism 102, and a movably disposed clutch output shaft 103. The clutch output shaft is selectively connected to one of the first gear shift mechanism 101 and the second gear shift mechanism 102. When the clutch output shaft moves to a first position, it is connected to the first gear shift mechanism 101 to drive the processing component to output a first speed. When the clutch output shaft moves to a second position, it is connected to the second gear shift mechanism 102 to drive the processing component to output a second speed. Both the first transmission mechanism 101 and the second transmission mechanism 102 are fixedly installed. When the clutch output shaft is in the first position, it outputs a first speed to adapt to multi-functional cooking. When the clutch output shaft is in the second position, it outputs a second speed to adapt to multi-functional cooking with different speed requirements. This allows for the replacement of processing components and the switching of speeds. Furthermore, the speed switching via mechanical position ensures high reliability. The clutch output shaft has a wide output speed range and high torque, greatly improving the reliability and versatility of multi-functional cooking. This configuration ensures that the transmission 100 itself operates stably with low noise when outputting the first or second speed, providing a good user experience.

[0041] The clutch output shaft 103 includes a first transmission part and a second transmission part. When the clutch output shaft moves to a first position, it is connected to the first speed change mechanism 101 through the first transmission part and outputs a first speed. When the clutch output shaft moves to a second position, it is connected to the second speed change mechanism 102 through the second transmission part and outputs a second speed. The clutch output shaft is provided with multiple transmission parts, which are connected to different speed change mechanisms. This ensures stable and reliable switching and coordination between the transmission parts and the speed change mechanisms, preventing misalignment, resonance noise, and gear jamming. Furthermore, the speed change is achieved entirely through the clutch output shaft via mechanical means, resulting in high torque and precise speed control. The installation and positioning of the machined components and the clutch output shaft are also simplified. The processing components are detachably connected to the clutch output shaft. Different processing components can be replaced according to the multi-functional processing type. The structure is simple and the operation is convenient. In particular, the clutch output shaft, as an output source with different speeds, can be connected to multiple different processing components. One or more processing components can be assembled with the clutch output shaft to output a constant first speed, or multiple processing components can be assembled with the clutch output shaft to output different speeds. Each processing component or each group of processing components outputs a different speed for different functions of processing, or for fine-grained processing of the same function, such as fast or slow vegetable cutting, meat paste processing for making dumpling filling, and meat granule processing for making bun filling.

[0042] In this embodiment, the clutch output shaft 103 further includes a third position. When the clutch output shaft moves to the third position, the first transmission part and the second transmission part disengage from the first speed change mechanism 101 and the second speed change mechanism 102, respectively. At this time, the clutch output shaft does not output a non-zero speed. The third position can be used as a speed switching gear. The clutch output shaft disengages from the first position and enters the third position, and then moves from the third position to the second position, realizing reliable mechanical gear shifting and avoiding abnormal noise and wear of the transmission part during the switching from the first position to the second position. Of course, the third position can also be used as a specific zero-speed output state for specific processing programs of food processing machines such as soup makers. One or more third positions can be set, that is, multiple different third positions, for switching between two or more non-zero speed corresponding positions.

[0043] During the processing of the food processing machine, the processing component axially limits the clutch output shaft 103 to keep it in a first position to stably output a first speed, or in a second position to stably output a second speed. In this embodiment, different processing components 400 limit the clutch output shaft to different positions, or limit a specific speed, so that a specific processing component can output a specific speed to perform a specific function. This setting eliminates the need for user selection; users only need to place the required processing component, and after assembly, the processing component will automatically match the clutch output shaft to a specific position to output a specific speed. No human or program intervention is required, simplifying the multi-functional control program, optimizing human-machine interaction, and mechanically selecting or switching speeds, greatly improving the reliability of the entire machine. In addition, this setting completely eliminates the possibility of user misoperation causing the placed processing component to mismatch with the actual running processing program or processing speed, and also avoids processing failures or motor damage caused by user misoperation, improving the user experience. Moreover, it is simple to operate and meets the needs of users such as young office workers, stay-at-home mothers, chefs, and the elderly.

[0044] Specifically, such as Figure 1 as well as Figures 4 to 6 As shown, the first transmission mechanism 101 includes a first planetary output shaft, a first planetary gear 1012, and a first planetary carrier 1013. The second transmission mechanism 102 includes a second planetary output shaft 1021, a second planetary output shaft 1022, and a second planetary carrier 1023. The first transmission mechanism 101 and the second transmission mechanism 102 are connected in a transmission manner. The first transmission part is provided with a first transmission gear 1041, the first planetary output shaft is provided with a first meshing gear 106 that cooperates with the first transmission gear 1041, the second transmission part is provided with a second transmission gear 1051, and the second planetary output shaft 1021 is provided with a second meshing gear 107 that cooperates with the second transmission gear 1051. The first transmission gear 1041 and the first meshing gear 106 mesh axially or radially; and / or, the second transmission gear 1051 and the second meshing gear 107 mesh radially or axially. In this embodiment, as shown... Figure 4 As shown, when the clutch output shaft moves to the first position, the first transmission gear 1041 and the first meshing gear 106 engage radially, causing the clutch output shaft to output a first rotational speed, i.e., a high rotational speed, for transmission connection with processing components that have functions such as mincing meat, beating eggs, cutting vegetables, and chopping vegetables. Figure 5 As shown, when the clutch output shaft moves to the third position, the first transmission gear 1041 and the second transmission gear 1051 disengage from the first meshing gear 106 and the second meshing gear 107, respectively, so that the clutch output shaft is in neutral and at zero speed. Figure 6As shown, the second transmission tooth 1051 and the second meshing tooth 107 engage radially, causing the clutch output shaft to output a second speed, i.e., a low speed, for transmission connection with processing components that have functions such as juicing, kneading dough, and shaving ice. The distance between the upper end face of the first transmission tooth 1041 and the lower end face of the second transmission tooth 1051 is less than the distance between the lower end face of the first meshing tooth 106 and the upper end face of the second meshing tooth 107, so that the clutch output shaft remains independent during the switching between the first and second speeds, avoiding jamming. This reduces the axial displacement of the clutch output shaft when switching from the first position to the second position, making the position switching faster and more accurate.

[0045] Preferably, the gearbox includes an upper cover 108 and a lower cover 109. A portion of the upper cover 108 protrudes upward to form a mounting post 1081. The mounting post 1081 has a through hole for the clutch output shaft to pass through. A shaft seal 110 and a bearing 111 are provided inside the mounting post 1081. A splined connector 1031 is provided at the upper end of the clutch output shaft 103 for transmission engagement with a machined component. The first transmission mechanism is located below the second transmission mechanism. The first transmission mechanism, from bottom to top, specifically includes a first planetary support cover plate 1014, a first planetary gear 1012, a first planetary support 1013, and a first planetary output shaft. The second transmission mechanism, from bottom to top, includes a first planetary support cover plate 1014, a first planetary gear 1012, a first planetary support 1013, and a first planetary output shaft. The system comprises a second planetary support cover 1024, a second planetary output shaft 1022, a second planetary support 1023, and a second planetary output shaft 1021. The planetary output shaft and planetary support can be integral or separate. In this embodiment, the second planetary output shaft 1021 and the second planetary support 1023 are integrally formed. The first planetary output shaft and the first planetary support 1013 are integrally formed by secondary injection molding. The first planetary output shaft is a metal component. When the clutch output shaft is in the first position, the first transmission tooth 1041 at the lower end of the clutch output shaft engages with the first meshing tooth 106 on the first planetary output shaft. The first transmission mechanism also includes a first internal gear ring 1015, and the second transmission mechanism also includes a second internal gear ring 1025. In this embodiment, the first internal gear ring 1015 is integrally formed with the lower cover 109. It is understood that the second internal gear ring can also be integrally formed with the upper cover 108.

[0046] The gearbox 100 further includes an elastic reset member 112 for resetting the clutch output shaft 103. The elastic reset member allows the clutch output shaft to reset to a first position or a second position in its natural state, and outputs a rotational speed matching the properties of the machined component when the machined component is in place. In this embodiment, the elastic reset member is specifically a spring 1121. The gearbox 100 includes a first limiting structure and a second limiting structure to limit the clutch output shaft when it moves to the first and second positions, respectively. The gearbox 100 includes a first transmission mechanism 101 and a second transmission mechanism 102. The clutch output shaft is selectively connected to either the first transmission mechanism 101 or the second transmission mechanism 102. The first transmission mechanism 101 includes a first planetary output shaft, a first planetary gear 1012, and a first planetary carrier 1013. The second transmission mechanism 102 includes a second planetary output shaft 1021, a second planetary output shaft 1022, and a second planetary carrier 1023. The limiting structure is disposed within the gearbox. Specifically, the first planetary output shaft is provided with the first limiting structure, and / or the second limiting structure includes a bearing disposed within the gearbox 100. Specifically, the first limiting structure includes a limiting end face. The clutch output shaft includes a first transmission part and a second transmission part. When the clutch output shaft moves to a first position, the first transmission part abuts against the limiting end face for limiting. When the clutch output shaft moves to a second position, the second transmission part abuts against the bearing for limiting.

[0047] like Figure 2As shown, this embodiment also provides a cup assembly 200 for a food processor with the aforementioned gearbox 100, including a cup body 201, a cup lid 202, and a processing component 400 disposed within the cup body. It also includes the gearbox 100, which comprises a first transmission mechanism 101, a second transmission mechanism 102, and a movably disposed clutch output shaft 103. When the clutch output shaft moves to a first position, it is connected to the first transmission mechanism 101 to drive the processing component to output a first rotational speed. When the clutch output shaft moves to a second position, it is connected to the second transmission mechanism 102 to drive the processing component to output a second rotational speed. The processing component is detachably connected to the clutch output shaft, and the cup lid 202 is installed in place, causing the clutch output shaft to remain in either the first or second position. Specifically, the cup lid axially limits the processing components, causing the clutch output shaft to move axially and be in a first or second position to output a constant first speed or a constant second speed. Preferably, the processing components include a first processing component and a second processing component. The cup lid and the cup body are fitted in the same position, and the first processing component axially limits the clutch output shaft in the first position, while the second processing component axially limits the clutch output shaft in the second position. This setting ensures that the cup lid mounting position is constant and uniquely determined. However, the cup lid in the same position can be matched with different processing components to limit the clutch output shaft to output different speeds in different positions. In this embodiment, different processing components limit the clutch output shaft to different positions through different positioning structures.

[0048] The cup lid 202 is provided with a limiting part 203 for limiting the movement of the processing component. The processing component abuts against the limiting part and the clutch output shaft respectively. The limiting part is a limiting shaft, a limiting hole, or a limiting step. In this embodiment, the limiting part includes a limiting hole 2031. Specifically, a limiting post is provided at the center of the bottom of the cup lid 202, and the limiting hole 2031 is provided inside the limiting post. One end of the processing component is provided with an abutting shaft 401 that abuts against the limiting hole, and the other end is provided with a positioning structure 402. The processing component is installed in place and abuts against the clutch output shaft through the positioning structure.

[0049] like Figure 3As shown, this embodiment also provides a food processing machine 300 with the gearbox 100, including a main unit 302, a cup assembly with the gearbox 100, and a processing component driven by a motor 301. In this embodiment, the first speed is greater than the second speed. The first speed is the speed at which the initial power of the motor is output to the clutch output shaft after passing through the first speed change mechanism 101 of the gearbox 100 when the clutch output shaft 103 is in the first position. The second speed is the speed at which the initial power of the motor is output to the clutch output shaft after passing through the first speed change mechanism 101 and the second speed change mechanism 102 of the gearbox 100 when the clutch output shaft 103 is in the second position. Both the first speed change mechanism and the second speed change mechanism are reduction mechanisms. The first speed is used for fast processing such as beating eggs, mincing meat, and crushing ice, while the second speed is used for slow processing such as kneading dough, juicing, and making ice cream. Preferably, the food processing machine also includes a water supply device and a valve assembly to achieve automatic water intake, automatic pulp discharge, and automatic cleaning.

[0050] The cup assembly 200 includes a cup body 201 and a plurality of replaceable processed components. Each processed component is connected to a clutch output shaft 103 and has a positioning structure that engages with and axially positions the clutch output shaft. At least one processed component has a different positioning structure than the others. Specifically, each processed component has a transmission hole 403 that engages with and drives the clutch output shaft. The positioning structure includes the inner wall of the transmission hole, or it may include a positioning ring, protrusion, groove, or step disposed within the transmission hole. In this embodiment, different processed components have different positioning structures, and these structures are at different heights relative to the bottom wall of the cup body, thereby limiting the clutch output shaft. Specifically, the processed components include a first processed component and a second processed component. The first processed component has a first positioning structure at its bottom end, and the second processed component has a second positioning structure at its bottom. The first positioning structure is used to limit the clutch output shaft to a first position to output a first rotational speed, and the second positioning structure is used to limit the clutch output shaft to a second position to output a second rotational speed.

[0051] Preferably, the bottom center of the cup body protrudes upward to form a mounting post 1081. The mounting post 1081 has a through hole for the clutch output shaft 103 to pass through. The upper end of the clutch output shaft has a connector that extends into the transmission hole. Specifically, the connector is a spline connector 1031, and the transmission hole has a spline hole that mates with the spline connector. The first processing component is limited to the clutch output shaft or the mounting post 1081 by a first positioning structure, and the second processing component is limited to the clutch output shaft or the mounting post 1081 by a second positioning structure. In this embodiment, the positioning structure limits the clutch output shaft or the mounting post 1081, and the clutch output shaft is axially limited to a first position or a second position by the positioning structure, and is responsible for outputting the speed corresponding to the corresponding position. In this embodiment, the mounting post 1081 is part of the gearbox 100, and the upper end of the upper cover 108 partially protrudes upward from the bottom of the cup body to form the mounting post 1081.

[0052] In this embodiment, multiple first processing components are provided, each of which is provided with a first positioning structure; and / or, multiple second processing components are provided, each of which is provided with a second positioning structure. Specifically, in this embodiment, the first processing component includes a meat grinder and an egg beater, and the second processing component includes a dough mixer and a screw extrusion juicing assembly. The gearbox 100 includes an upper cover 108 and a lower cover 109, and the cup body includes a mounting cavity 2011 for mounting the gearbox. The mounting cavity has an opening at its lower end, and the cup body includes a bottom wall that covers the opening, or the lower cover 109 forms the bottom wall of the cup body. In this embodiment, the cup body includes a mounting cavity for mounting the gearbox 100, the lower cover 109 forms part of the bottom wall of the cup body, and the upper cover 108 forms part of the inner bottom surface of the cup body and the outer surface of the mounting post 1081. This configuration simplifies the connection structure between the gearbox 100 and the cup body, and significantly reduces the height of the cup body. The clutch output shaft 103 movably passes through the upper cover 108 and is sealed to the upper cover 108. The mounting cavity 2011 includes an upper opening and a lower opening, with a sealing ring 204 at the upper opening and a shock-absorbing ring at the lower opening.

[0053] Specifically, in this embodiment, the gearbox 100 is located at the bottom of the cup body. The bottom of the cup body has an output shaft 114 extending from the bottom of the gearbox 100 and a connector 113 located at the lower end of the output shaft. The upper end of the output shaft has a bearing 111 and a sun gear 115, transmitting the initial power of the motor to the transmission mechanism. One end of the connector is connected to the first transmission mechanism 101 within the gearbox 100, and the other end is connected to the motor output shaft. In this embodiment, the food processor is a multi-functional, hands-free blender. The main unit has a processing chamber 303 with an opening at the top. The processing chamber contains a motor-driven pulverizing blade. The cup body with the gearbox 100 covers the opening of the processing chamber. The processing component is connected to the pulverizing blade via the connector. The motor power is transmitted to the processing component through the pulverizing blade, connector, and gearbox, enabling multi-functional food processing. The connector includes a connecting shaft hole disposed in the gearbox 100 and drivenly connected to the clutch output shaft, and the pulverizing blade has a protrusion that mates with the connecting shaft hole; or, the connector 113 includes a pawl 1131 disposed in the gearbox 100 and drivenly connected to the clutch output shaft, the pawl engaging and driving with the pulverizing blade. In this embodiment, the connector includes a pawl, the pawl including a body and a claw portion circumferentially disposed on the body. The pulverizing blade has a engaging portion that engages with the claw portion, preferably a slot, which makes the transmission stable, the transmission noise low and the service life long.

[0054] Specifically, such as Figure 7 As shown, the first processing component includes a meat grinder 500, which includes a blade shaft body 501 and a detachable blade 502. The bottom of the blade shaft body has a transmission hole 403. The positioning structure 402 includes a positioning ring 503 disposed within the transmission hole. The positioning ring 503 abuts against the splined connector at the upper end of the clutch output shaft and axially limits the clutch output shaft. It is understood that the meat grinder structure can also be optimized. A gap and an elastic post are provided between the top of the clutch output shaft and the top wall of the transmission hole. The elastic post can dynamically and adaptively adjust the meat grinder to prevent jamming, but does not affect the axial positioning of the clutch output shaft by the positioning structure to maintain its first position. The first processing component also includes an egg beater. Preferably, the egg beater includes a blade shaft body shared with the meat grinder, and an egg-beating part that is replaced and installed on the blade shaft body along with the meat grinder blade. The egg-beating part includes a through hole that can be fitted onto the blade shaft body. The positioning structure includes a positioning ring disposed on the blade shaft body.

[0055] like Figure 8As shown, the second processing component includes a dough-kneading rod 600, which includes a dough-kneading rod body 601 and a rod portion 602. The bottom of the dough-kneading rod body is provided with a transmission hole 403. In this embodiment, due to the action of the spring force, the clutch output shaft is located in the second position and outputs the second speed in its natural state. Therefore, the second processing component does not need to be provided with a positioning structure for positioning the clutch output shaft 103. Alternatively, it can be understood that the second processing component is provided with a second positioning structure, and the second positioning structure is in contact with the clutch output shaft without force or the second positioning structure is provided with a gap between it and the clutch output shaft. At this time, it is only necessary to ensure that the clutch output shaft and the second processing component can transmit torque through transmission. In this embodiment, the second positioning structure also includes a positioning step 603 for auxiliary positioning with the mounting post 1081 of the upper cover 108 of the gearbox. The positioning step abuts against the mounting post 1081 to prevent the kneading rod from wobbling radially. The cup lid closes and presses the kneading rod axially through the limiting hole, so that the positioning step on the kneading rod remains abutting against the mounting post 1081 to limit the kneading rod, thereby ensuring reliable transmission of the clutch output shaft to the second processing component and constant output of the second speed. The second processing component also includes a juicer assembly that can be replaced with the kneading rod.

[0056] Understandable, such as Figure 9 As shown, this embodiment also provides a solution for applying the gearbox 100 to a common blender. A common blender includes a main unit, which has a high-speed processing chamber assembly. The processing chamber assembly includes a processing chamber body and a pulverizing blade. The processing chamber assembly is detachably mounted relative to the main unit. It also includes a cup assembly with the gearbox 100, which is replaceable with the processing chamber assembly. The cup assembly includes a cup body 201 and a detachable processing component. The cup body has the gearbox 100, and the processing component is connected to the gearbox 100 via a clutch output shaft. The main unit has an upper connector for connecting to a motor, and the bottom of the cup body has a lower connector for connecting to the upper connector. When the cup assembly is mounted on the main unit, motor power is transmitted to the processing component via the lower connector, the upper connector, and the gearbox 100 with the clutch output shaft. The gearbox 100 includes a fixed first gear shift mechanism 101 and a second gear shift mechanism 102, and a movable clutch output shaft. The clutch output shaft is selectively connected to either the first gear shift mechanism 101 or the second gear shift mechanism 102. When the clutch output shaft moves to a first position, it is connected to the first gear shift mechanism 101 to drive the processing component to output a first speed. When the clutch output shaft moves to a second position, it is connected to the second gear shift mechanism 102 to drive the processing component to output a second speed.

[0057] Understandably, the first planetary output shaft is provided with a first limiting structure, and the second limiting structure is disposed within the upper cover 108 of the gearbox, specifically as a limiting step of the upper cover 108. Alternatively, the first limiting structure is disposed on the first planetary support 1013, and the second limiting structure includes a bearing disposed within the gearbox 100.

[0058] Understandably, the distance between the clutch output shaft and the gearbox remains constant in the first and second positions. That is, the clutch output shaft moves relative to the gearbox to change the output speed. This setting reduces the axial height and allows the position of the processing parts relative to the cup to be adaptably changed, meeting the needs of richer cooking functions and processing attributes.

[0059] Example 2 like Figures 10 to 12 As shown, this embodiment provides a miniaturized gearbox 100 for use in a food processing machine. Specifically, the first transmission gear 1041 and the first meshing gear 106 mesh radially, while the second transmission gear 1051 and the second meshing gear 107 mesh axially, thereby significantly reducing the outer diameter of the transmission mechanism or gearbox 100 where the second transmission gear 1051 and the second meshing gear 107 are located. This optimizes the overall space of the food processing machine.

[0060] Specifically, the gearbox 100 includes a fixedly configured first transmission mechanism 101 and a second transmission mechanism 102, and a movably configured clutch output shaft 103. The clutch output shaft is selectively connected to either the first transmission mechanism 101 or the second transmission mechanism 102. When the clutch output shaft moves to a first position, it is connected to the first transmission mechanism 101 to drive the processing component 400 to output a first speed. When the clutch output shaft moves to a second position, it is connected to the second transmission mechanism 102 to drive the processing component to output a second speed.

[0061] The first transmission mechanism 101 includes a first planetary carrier 1013, a first central gear shaft 1016, and a first planetary gear 1012. The second transmission mechanism 102 includes a second planetary carrier 1023, a second central gear shaft 1026, and a second planetary output shaft 1022. The first and second transmission mechanisms are connected via the first planetary carrier 1013 and the second central gear shaft 1026. A flat section or spline is provided between the second central gear shaft 1026 and the first planetary carrier 1013. The transmission also includes an elastic reset member for resetting the clutch output shaft. In this embodiment, the elastic reset member includes an elastic connecting shaft disposed between the second central gear shaft and the first central gear shaft. The elastic connecting shaft includes a connecting shaft 1122 and a spring 1121 to elastically reset the clutch output shaft, so that the clutch output shaft is in a second position under normal conditions. The connecting shaft passes through the second central gear shaft 1026 and abuts against the lower end of the clutch output shaft.

[0062] The clutch output shaft 103 includes a first transmission part 104 and a second transmission part 105. The first transmission part includes a first transmission gear 1041, and the second transmission part includes a second transmission gear 1051. The second central gear shaft 1026 is provided with a first meshing gear 106 that meshes with the first transmission gear 1041. The second planetary support 1023 is provided with a second meshing gear 107 that meshes with the second transmission gear 1051. The first transmission gear 1041 and the first meshing gear 106 are radially meshed, causing the clutch output shaft to output a first speed, i.e., a high-speed gear, for transmission connection with processing components that have functions such as mincing meat, beating eggs, and chopping vegetables. The first transmission gear 1041 and the second transmission gear 1051 are disengaged from the first meshing gear 106 and the second meshing gear 107, respectively, causing the clutch output shaft to be in neutral with zero speed. The second transmission gear 1051 and the second meshing gear 107 are axially meshed, causing the clutch output shaft to output a second speed, i.e., a low-speed gear, for transmission connection with processing components that have functions such as juicing, kneading dough, and shaved ice. The first meshing tooth 106 on the second center tooth extends axially, and the corresponding first transmission tooth 1041 also extends axially and meshes with the first meshing tooth 106 axially. There are three meshing teeth and three transmission teeth, and each is provided with a guide structure.

[0063] Example 3 like Figure 13 As shown, this embodiment also provides a food processor with a simple user interface and integrated operation functions and buttons, including a main unit and a multifunctional cup assembly 200 mounted on the main unit. The cup assembly includes a cup body 201, a detachable processing component 400, and a cup lid. The cup body is equipped with a gearbox 100 with a clutch output shaft. The gearbox 100 includes a fixedly mounted first gear mechanism 101 and a second gear mechanism 102, and a movable clutch output shaft 103. The clutch output shaft is selectively connected to either the first gear mechanism 101 or the second gear mechanism 102. When the clutch output shaft moves to a first position, it is connected to the first gear mechanism 101 to drive the processing component to output a first speed. When the clutch output shaft moves to a second position, it is connected to the second gear mechanism 102 to drive the processing component to output a second speed. The processing component 400 is equipped with a positioning structure for axially positioning the clutch output shaft, so that the clutch output shaft is held in the first position and outputs the first speed, or held in the second position and outputs the second speed.

[0064] The main unit is equipped with an operation panel 304, which has a multi-function button 305. Each multi-function button corresponds to at least two processing programs with different speeds. Specifically, the multi-function button is electrically connected to a control module. When the user triggers the multi-function button, the control module activates the control module. Based on the multi-function button command, the control module controls the motor to output an initial constant speed. The processing components include a first processing component and a second processing component. The first processing component has a first positioning structure to limit the clutch output shaft to a first position, and the second processing component has a second positioning structure to limit the clutch output shaft to a second position. The user places either processing component into the cup body and closes the lid to ensure effective and reliable positioning of the processing component on the clutch output shaft. After the cup body assembly is in place, pressing the multi-function button activates the speed corresponding to the processing component. The first processing component can be a meat grinder or an egg beater, and the second processing component can be a dough mixer or a juicer. This design highly integrates the button functions of the control panel, allowing a single button to correspond to multiple multi-functional processing programs. By using different positioning structures for different processing components, the mechanical structure automatically identifies the rotation speed, accurately identifies the processing program, and performs specific functions. Users only need to assemble the processing component with the required function into the cup and press the multi-functional button. There is no need for detailed function button identification or selection, which can achieve accurate identification and program matching between the processing component and the corresponding function. This avoids the problem of misoperation due to mismatch between input instructions and actual processing components, making it very suitable for people of all ages.

[0065] Example 4 like Figure 14 As shown, this embodiment provides a food processing machine, specifically a multi-functional power-driven meat grinder, including a cup assembly 200. The cup assembly includes a cup body with an opening at the top, a processing component detachably disposed within the cup body, and a cup lid that covers the opening of the cup body. The cup lid contains a motor and a gearbox 100 with a downwardly extending clutch output shaft. The gearbox 100 includes a first transmission mechanism 101 and a second transmission mechanism 102 fixedly disposed. The clutch output shaft 103 is selectively connected to one of the first transmission mechanism 101 and the second transmission mechanism 102. When the clutch output shaft moves to a first position, it is connected to the first transmission mechanism 101 to drive the processing component to output a first speed. When the clutch output shaft moves to a second position, it is connected to the second transmission mechanism 102 to drive the processing component to output a second speed. The lower end of the processing component is positioned to abut against the cup body, and the upper end of the processing component is positioned by a positioning structure. The first processing component includes one or more replaceable or combinable meat grinders and / or egg beaters, and the second processing component includes a dough mixer or a juicer assembly.

[0066] Example 5 like Figure 15 As shown, this embodiment provides a bottom-mounted integrated food processor with a gearbox 100 housed inside the main unit and multiple uses per cup. Specifically, it is a multi-functional food processor, including a main unit, the gearbox 100, and a cup assembly. The gearbox 100 is housed inside the main unit and is connected to a motor. The cup assembly 200 includes a cup body fixedly mounted on the main unit, a lid that covers the opening of the cup body, and a detachable processing component housed inside the cup body. The processing component is connected to the gearbox clutch output shaft 103, and multiple processing components can be used interchangeably.

[0067] Understandably, the cup body can be improved to be detachable from the main unit. Specifically, the cup body assembly also includes an intermediate connecting shaft that is linked to the clutch output shaft. The intermediate connecting shaft is located at the bottom of the cup body and extends partially into the cup body. The end of the clutch output shaft that does not extend into the cup body is connected to the clutch output shaft, and the end that extends into the cup body is connected to a detachable processing component. This allows the cup body with the intermediate connecting shaft to be shared, the processing component to be replaceable, and after the cup lid is closed onto the upper port of the cup body, it directly or indirectly limits the processing component, the intermediate connecting shaft, and the clutch output shaft, so that different processing components limit the axial position of the clutch output shaft in different ways, thereby outputting different speeds. Specifically, the first processing component has a first positioning structure, and the second processing component has a second positioning structure. The positioning structure abuts against the intermediate connecting shaft to position the clutch output shaft and the intermediate connecting shaft at a specific speed output position. For example, the first processing component is installed in place and the intermediate connecting shaft and the clutch output shaft are held in a first position to output a first speed, and the second processing component is installed in place and the intermediate connecting shaft and the clutch output shaft are held in a second position to output a second speed.

[0068] Example 6 This embodiment provides a food processing machine with a single processing component that outputs two speeds. Specifically, it includes a main unit, a motor, and a cup assembly. The cup assembly includes a cup body, a lid, and the processing component. The food processing machine also includes a gearbox with a clutch output shaft. The processing component is drive-connected to the gearbox clutch output shaft, and the processing component is not detachable from the cup body. When the lid is closed to the cup body opening, it directly or indirectly limits the clutch output shaft to output a first speed at a first position, or directly or indirectly limits the clutch output shaft to output a second speed at a second position. Specifically, the clutch output shaft has a blocking part to prevent the processing component from disengaging from the clutch output shaft and the cup body. The lid has a first mounting position and a second mounting position for mounting to the cup body opening. The first and second mounting positions have different heights. The lid axially limits the clutch output shaft to the first and second positions respectively, allowing it to output the first and second speeds respectively. In this embodiment, the first mounting position is a screw-on first step, the second mounting position is a screw-on second step, the cup body opening is provided with a first slot and a second slot respectively cooperating with the screw-on first step and the screw-on second step, the cup lid is provided with a limiting part, the cup lid abuts against the processing part through the limiting part, the processing part abuts against the clutch output shaft, thereby indirectly limiting the clutch output shaft to different positions.

[0069] Understandably, the stirring element can also be detached from the clutch output shaft or the cup body.

[0070] Understandably, the processing component is sleeved through the clutch output shaft, the processing component is provided with an anti-rotation part relative to the clutch output shaft, and the cup cover can be limited by directly contacting the clutch output shaft through the limiting part.

[0071] In addition to the preferred embodiments described above, the technical solutions protected by this invention are not limited to the above embodiments. It should be noted that the combination of multiple technical solutions in any one embodiment, as well as the combination of technical solutions in any one embodiment with technical solutions in one or more other embodiments, are within the scope of protection of this invention.
