Abstract
Description
Technical Field
[0001] This application relates to the field of food processing machines, specifically to a multi-functional food processing machine. Background Technology
[0002] To achieve multiple functions, the food processor is equipped with different output connectors. By engaging with the corresponding processing cup connectors and utilizing a reduction gear mechanism, it can output different speeds and torques, enabling the processing of various ingredients. This enriches user needs while ensuring effective pulverization of different ingredients. The applicant has long been aware that this structural design presents technical problems: when the reduction output is not needed, the reduction gear mechanism continues to idle, leading to increased noise and wear. To address these technical issues, the applicant has explored several different solutions.
[0003] An existing food processing machine, such as the product disclosed in patent CN201821963250.5, has a motor shaft forming a first drive unit that drives the processing components to rotate, and a main output end of a main reducer forming a second drive unit that drives the processing components to rotate. By adapting the first and second drive units to different processing cups, different output speeds can be achieved to drive the processing components to rotate, thereby processing different ingredients. In this solution, at high-speed output, the drive teeth and driven teeth separate, and the reducer does not rotate synchronously, solving the problem of synchronous rotation when the reducer does not need to output. However, at low-speed output, the above solution compresses the first drive ring, causing the transmission shaft to move downwards. This results in the transmission shaft and motor shaft continuously moving axially while outputting rotational torque, reducing the transmission stability and reliability between the transmission shaft and the rotating shaft. Furthermore, friction between the transmission shaft and the rotating shaft leads to increased noise and transmission vibration. Additionally, there is a speed difference between the trigger pin that pushes the first drive ring and the first drive ring or transmission shaft, resulting in relative friction between the trigger pin and the first drive ring or transmission shaft.
[0004] To address the friction issue caused by the simultaneous rotation of two drive heads, patent CN202111359272.7 discloses a food processing machine that allows different output connectors to operate selectively, thus meeting the processing needs at different speeds. While this product avoids wear between components and reduces noise, it requires an electrically driven clutch device to switch between different speeds. This not only results in high configuration costs and a complex structure, but also makes the entire machine prone to malfunction and failure to operate normally when there is a power failure in the electric drive or a transmission failure between structural components, making it difficult to guarantee the reliability of the product. Utility Model Content
[0005] This application provides a multi-functional food processing machine, which aims to solve the technical problems of friction between components, increased noise and wear, and complex structure and large space volume caused by using an electric drive clutch structure to control the linkage or separation of the motor shaft and the reduction mechanism in the existing configuration with a high-speed output section and a low-speed output section, under the premise that the reduction mechanism does not work when the low-speed output section does not need to output.
[0006] The technical solution adopted in this application is as follows:
[0007] A multifunctional food processor includes a main unit with a built-in motor and multiple replaceable food processing cups mounted on the main unit. Each food processing cup contains a pulverizing component driven by the motor. The main unit includes a reduction gear mechanism and a clutch structure. The clutch structure controls the start and stop of the reduction gear mechanism. The reduction gear mechanism includes a sun gear and a planetary gear assembly. The clutch structure includes a movable component positioned above the sun gear, a drive gear on the motor shaft, and a driven gear on the inner wall of the sun gear. The sun gear is sleeved outside the motor shaft and can slide axially along the motor shaft to allow the drive gear and the driven gear to mesh or disengage. The motor shaft has a high-speed output section, and the output end of the planetary gear assembly has a low-speed output section. A first food processing cup, corresponding to the high-speed output section, has a trigger section. The trigger section presses down on the movable component, which in turn presses down on the sun gear, causing the drive gear and the driven gear to disengage.
[0008] In this technical solution, the high-speed output section is directly mounted on the motor shaft of the motor, eliminating the need for a transmission structure and ensuring stable and reliable high-speed output. Furthermore, this application incorporates a clutch structure to prevent the reduction mechanism from idling when not in use, thus preventing structural wear and increased noise. The clutch structure controls the start and stop of the reduction mechanism, allowing it to remain stationary during high-speed motor output, reducing noise and extending its lifespan. Additionally, the high-speed and low-speed output sections can operate independently of different blending cups, eliminating friction between them and preventing noise and wear issues. The first blending cup has a trigger mechanism; by installing a linkage triggering component, the sun gear moves, disengaging the reduction mechanism from the motor shaft. This prevents the reduction mechanism from operating during high-speed motor output. The mechanical triggering of the clutch structure improves the reliability of the reduction mechanism's start and stop control, ensuring normal machine operation. The trigger mechanism is located on the first blending cup, eliminating the need for an additional trigger structure within the main unit, simplifying the structure, saving space, and promoting miniaturization. Compared with the applicant's earlier technical solutions, in this technical solution, the sun gear is sleeved outside the motor shaft and can slide along the axial direction of the motor shaft. When high-speed output is achieved, the trigger part pushes the movable part and further drives the sun gear to separate from the drive gear, thus realizing the disengagement of power. The function of the movable part is relatively simple, only needing to push the sun gear, and does not need to participate in the transmission output. Therefore, it can ensure the stability and efficiency of the clutch state, and there is no technical problem of mutual friction between the movable part and the sun gear, planetary gear assembly, etc. At the same time, the movable part works directly by the pressure of the blending cup, without the need for a separate motor or other drive mechanism, occupying less space and having higher transmission reliability.
[0009] Optionally, the reduction mechanism further includes a gearbox fixedly connected to the host, the planetary gear assembly is disposed inside the gearbox and the low-speed output part extends from the upper end of the gearbox, and the sun gear moves downward and separates from the planetary gear assembly.
[0010] As the sun gear is pushed downward and separates from the drive gear, it further separates from the planetary gear assembly. This ensures complete separation between the motor shaft and the reduction mechanism. Furthermore, the clutch mechanism only needs to push the sun gear axially when it is pushed, without having to drive the entire reduction mechanism. This means that the user does not need to apply a large force when pushing the moving part, and it also ensures that the low-speed output part of the planetary gear assembly remains in a stable output position.
[0011] Optionally, the clutch structure includes a first elastic member disposed below the movable member, and the movable member moves upward to reset under the elastic action of the first elastic member, so as to remove the downward pressure on the sun gear.
[0012] In this technical solution, by setting a first elastic element, when the first food processor cup is removed, the first elastic element can drive the movable part to move quickly back to the initial position through its own elasticity, thereby removing the downward pressure of the movable part on the sun gear, providing conditions for the meshing of the drive gear and the driven gear, so that when the motor needs to reduce speed and output work in the future, the reduction mechanism can be linked with the motor shaft to ensure the normal operation of the reduction mechanism.
[0013] Optionally, the clutch structure includes a second elastic element disposed below the sun gear. The sun gear moves upward under the elastic action of the second elastic element, causing the driving tooth and the driven tooth to mesh.
[0014] In this technical solution, by setting a second elastic element, when the sun gear is not pressed down, the second elastic element can drive the sun gear to move upward to ensure that the sun gear reaches the position where the drive tooth and the driven tooth mesh, so as to ensure that the subsequent reduction mechanism can work normally and improve the reliability of the machine.
[0015] Optionally, the upper end of the movable part is provided with at least two push rod heads arranged opposite to each other and connected to each other. The trigger part is a downwardly extending trigger rib provided at the bottom of the first cooking cup. The trigger rib is used to press down the push rod head. The trigger rib is strip-shaped and has the same number as the push rod head, or the trigger rib is an annular trigger rib.
[0016] In this technical solution, when the first blending cup is installed, the trigger rib at its bottom can smoothly press down the push rod head, making the cup installation and the triggering of the deceleration mechanism a seamless process without additional operation, thus improving ease of use. The trigger rib has a simple structure and does not increase the processing difficulty of the cup. When at least two strip-shaped trigger ribs are used to trigger the corresponding push rod head, this configuration requires less material, saving costs, and ensuring that the moving parts move smoothly as a whole without tilting, thus ensuring the pressing effect of the moving parts on the sun gear. When an annular trigger rib is used, regardless of the angle at which the first blending cup is installed circumferentially, the trigger rib can abut against the push rod head to press down the push rod head, eliminating the need for alignment operation between the trigger rib and the push rod head. For users, the operation of installing the cup is simpler and easier, improving the user experience.
[0017] Optionally, the lower end of the movable member is provided with at least two push rods arranged opposite to each other and connected, or the lower end of the movable member is provided with an annular push rod, the push rod being used to press down the sun gear.
[0018] In this technical solution, when at least two oppositely arranged push rods are used to press down the sun gear, the structure of the moving parts can be simplified, the processing materials can be reduced, and the cost can be saved while ensuring the overall smooth movement of the sun gear. When a ring push rod is used, the force exerted on the sun gear by the ring push rod is more balanced, which promotes the smooth movement of the sun gear and reduces the probability of deformation caused by local force concentration on the sun gear, thus extending the service life of the components.
[0019] Optionally, the first cooking cup includes a cup body with an opening at the bottom and a cup lid that closes the opening. The cup lid is detachably installed on the cup body, and the trigger portion extends downward from the bottom of the cup lid.
[0020] In this technical solution, the trigger part is formed on the cup lid, which is a detachable structure. Cup lids with trigger parts of different shapes or distributions can be processed as needed to provide different trigger structures by replacing the cup lid when needed, thereby improving the flexibility of use. Moreover, when the trigger part is damaged, only the cup lid needs to be replaced, which can avoid replacing the entire cooking cup and causing waste and increased costs.
[0021] Optionally, the motor shaft is provided with a first bearing, the first bearing having an annular limiting part, the outer diameter of the annular limiting part being larger than the inner diameter of the movable part, the annular limiting part being used to restrict the upward movement of the movable part.
[0022] In this technical solution, by limiting the upward movement of the movable part, it is possible to prevent the movable part from falling out of its corresponding installation position and interfering with other components when it is lifted up, thus ensuring that the movable part floats up and down within a suitable stroke range and thereby ensuring the reliability of the movable part.
[0023] Optionally, the trigger part and the low-speed output part are sequentially disposed on the radial outer side of the high-speed output part. The low-speed output part is provided with a mounting cavity, the movable part is disposed in the mounting cavity, and a guide post is provided in the mounting cavity. The movable part moves up and down along the guide post.
[0024] In this technical solution, the larger internal space of the low-speed output section can be used to install the moving parts, reducing the use of the installation structure and making the internal structure of the main unit more compact, thus promoting the miniaturization of the main unit. By moving the moving parts up and down along the guide column, the stability of the moving parts can be improved, so that the moving parts always maintain a stable posture, thereby ensuring the downward pressure effect of the moving parts on the sun gear.
[0025] Optionally, the mounting cavity is provided with a positioning post, and the clutch structure includes a first spring located below the movable member. The first spring is fixed on the positioning post, and the first spring is compressed when the movable member moves downward.
[0026] In this technical solution, the low-speed output section also provides a mounting position for the first spring, which can further promote the compactness of the structural layout. Moreover, the first spring is sleeved on the positioning post, which can ensure that the first spring only deforms in the axial direction, avoids the first spring deforming in the radial direction from affecting the pushing effect on the moving part, and ensures that the moving part can be reliably reset.
[0027] Optionally, a second bearing is provided between the motor shaft and the sun gear, and a second elastic element and a bracket are sequentially provided below the sun gear. The upper end of the second elastic element is limited by the second bearing, and the lower end of the second elastic element is limited by the bracket. The second elastic element is used to push the sun gear to move upward. When the deceleration mechanism is working, the sun gear, the second elastic element and the bracket rotate synchronously.
[0028] In this technical solution, by setting a second bearing, the cooperation between the sun gear and the motor shaft can be ensured and they can rotate relative to each other. When the reduction mechanism is working, the sun gear, the second elastic element and the bracket rotate synchronously, which can avoid interference or increased noise caused by friction between the sun gear and the second elastic element when the sun gear rotates, thereby ensuring the normal operation of the reduction mechanism.

[0046] like Figures 1 to 9As shown, this application provides a multifunctional food processor, including a main unit with a built-in motor 13 and a food processor cup mounted on the main unit. Preferably, the food processor cup is provided in multiple and interchangeable. The food processor cup contains a pulverizing component driven by the motor 13. The main unit contains a reduction mechanism and a clutch structure. The reduction mechanism controls the start and stop through the clutch structure. The reduction mechanism includes a sun gear 10 and a planetary gear assembly 11. The clutch structure includes a movable component 12 disposed above the sun gear 10, a drive gear 14 disposed on the motor shaft 131 of the motor 13, and a driven gear 15 disposed on the inner sidewall of the sun gear 10. The sun gear 10 is sleeved on the outside of the motor shaft 131, allowing the sun gear 10 to rotate relative to the motor shaft 131. The sun gear 10 can slide along the axial direction of the motor shaft 131, thereby enabling the drive gear 14 and the driven gear 15 to mesh or disengage. When the drive gear 14 and the driven gear 15 mesh, the drive gear 14 drives the sun gear 10 to rotate synchronously. When the drive gear 14 and the driven gear 15 disengage, the sun gear 131 receives no power input and does not rotate. At this time, the sun gear 10 rotates relative to the motor shaft 131. The motor shaft 131 is provided with a high-speed output section 16, and the output end of the planetary gear assembly 11 is provided with a low-speed output section 17. The food processor includes multiple replaceable cooking cups. The first cooking cup 18, which is installed corresponding to the high-speed output section 16, is provided with a trigger section 181. The trigger section 181 is configured such that when the first cooking cup 18 is installed on the main unit, the trigger section 181 presses down the movable member 12, and the movable member 12 presses down the sun gear 10, causing the drive gear 14 and the driven gear 15 to separate.
[0047] In order to prevent the reduction mechanism from idling when it is not needed, thus avoiding structural wear and increased noise, the food processing machine of this application adopts a clutch structure to control the start and stop of the reduction mechanism. This allows the reduction mechanism to remain stationary when the motor 13 is operating at high speed, reducing noise, extending the service life of the reduction mechanism, and ensuring the basic requirement that the reduction mechanism does not operate when the low-speed output section is not working. Furthermore, the high-speed output section 16 and the low-speed output section 17 can selectively rotate to operate for different food processing cups, eliminating friction between the two output sections and avoiding noise and wear problems. The food processor cup 18 is equipped with a trigger unit 181. By installing the first food processor cup 18 and triggering the movable component 12, the sun gear 10 is moved, thereby disengaging the reduction mechanism from the motor shaft 131. This allows the reduction mechanism to remain inactive when the motor 13 is operating at high speed. The separation or linkage between the reduction mechanism and the motor shaft 131 is achieved through a mechanical trigger clutch mechanism, improving the reliability of the reduction mechanism's start-stop control and ensuring normal machine operation. The trigger unit 181 is formed on the first food processor cup 18, eliminating the need for an additional trigger structure within the main unit. This simplifies the structure, saves space, and promotes miniaturization of the main unit. Since the trigger unit 181 only needs to move the sun gear 10 to disengage the reduction mechanism from the motor shaft 131, without requiring the entire reduction mechanism to move together, stable output of the reduction mechanism, especially the low-speed output unit, is ensured, resulting in higher reliability of the food processor during operation.
[0048] The food processor of this application is equipped with different replaceable processing cups, each with different grinding or mixing components. Through the motor 13, different operating speeds are output, enabling various functions such as cell-wall breaking (e.g., making soy milk), slicing / shredding (e.g., mincing meat and vegetables), and dough kneading. A single machine can meet a user's diverse food processing needs, resulting in low purchase costs and significant convenience for daily life. In practical use, when high-speed output from the motor 13 is required, the user simply installs the first processing cup 18. Installing the first processing cup 18 triggers the clutch mechanism, separating the input end of the reduction gear from the motor shaft 131, i.e., separating the drive gear 14 and the driven gear 15. This reduces wear by decreasing the operating time of the reduction gear, thereby extending its service life. In this operating state, the grinding component of the first processing cup 18 rotates at the same speed as the motor shaft 131, resulting in a higher rotational speed. This increases the number of times the food is cut per unit time, enabling grinding and cell-wall breaking processes. The triggering unit 181 is directly triggered by the food processing cup and does not rely on a separate triggering system such as the control motor of the food processor. This results in higher reliability, a simpler structure, and reduces the space occupied by the deceleration mechanism, ultimately optimizing and reducing the overall size of the food processor.
[0049] Understandably, when low-speed output of motor 13 is required, the user can use other blending cups. By installing these other blending cups on the main unit, the drive gear 14 and driven gear 15 are engaged. In this operating state, the power from motor shaft 131 is transmitted to the pulverizing or mixing components in the corresponding blending cup through the clutch structure, reduction mechanism, and low-speed output unit 17. This causes the pulverizing or mixing components to output a speed lower than that of motor 13, thereby performing the corresponding pulverizing or mixing operation. For example... Figure 7 and Figure 8 As shown, the drive gear 14 is knurled onto the motor shaft 131 and can mesh with the driven gear 15 at the upper end of the sun gear 10. This structural design ensures that the two gears will not jam when they separate and rotate relative to each other and then mesh again, thus ensuring the reliability of the start-stop control of the reduction mechanism. After the sun gear 10 is pushed down, it always maintains a portion of its engagement with the planetary gear assembly 11, thereby ensuring that there is no risk of jamming when the sun gear 10 and the planetary gear assembly 11 are not misaligned, and improving operational reliability.
[0050] like Figure 1 and Figure 2 As shown, the first blending cup 18 is mounted on the main unit bracket 19, and the high-speed output unit 16 is connected to the pulverizing component of the first blending cup 18. When the first blending cup 18 is installed, the trigger part 181 on the first blending cup 18 presses down the movable part 12, causing the movable part 12 to press down the sun gear 10. The driven tooth 15 of the sun gear 10 separates from the drive tooth 14 on the motor shaft 131, so that the sun gear 10 does not rotate with the shaft, thereby preventing the planetary gear assembly 11 from rotating, and realizing the separation of the reduction mechanism from the motor shaft 131.
[0051] like Figure 3 As shown, when using the second blending cup 20, the second blending cup 20 is equipped with a connector 201, which engages with the low-speed output unit 17 to achieve synchronous rotation. The low-speed output unit 17 is fixed to the planetary gear assembly 11 by screws, compared to... Figure 1 In this embodiment, the movable part 12 is lifted up. After the movable part 12 is lifted up, it has no downward pressure on the sun gear 10. The sun gear 10 is lifted up so that the driven tooth 15 meshes with the driving tooth 14, thereby realizing that the sun gear 10 drives the planetary gear assembly 11 to rotate, so that the power of the motor 13 is transmitted to the pulverizing part of the second food processor 20 through the reduction mechanism, realizing the low-speed output of the motor 13.
[0052] In a preferred embodiment of this application, the reduction mechanism includes a gearbox 30 fixedly connected to the main unit, the planetary gear assembly 11 is disposed inside the gearbox 30, and the low-speed output part 17 is located at the top of the gearbox 30 and exposed on the top of the gearbox 30. Except for the sun gear 10, the rest of the reduction mechanism is fixed in the transmission position through the gearbox 30. Thus, when the user installs the first blending cup 18, the trigger part 181 presses down the movable part 12, and the movable part 12 only needs to press down the sun gear 10, without having to drive the entire reduction mechanism downward, resulting in less force and easier user operation. In addition, the low-speed output part 17 can always remain in a stable position and will not change its position when outputting at different speeds, thereby ensuring a stable and reliable transmission connection between the low-speed output part 17 and the first blending cup 17.
[0053] The clutch structure includes a first elastic element 21 located below the movable element 12. The movable element 12 moves upward and resets under the elastic action of the first elastic element 21 to remove the downward pressure on the sun gear 10.
[0054] In this embodiment, by providing a first elastic element 21, when the first food processor 18 is removed, the first elastic element 21 can drive the movable element 12 to quickly move and reset to its initial position through its own elasticity, thereby removing the downward pressure of the movable element 12 on the sun gear 10. This provides conditions for the meshing of the drive gear 14 and the driven gear 15, so that when the motor 13 needs to reduce its output speed, the reduction mechanism can be linked with the motor shaft 131 to ensure the normal operation of the reduction mechanism. The first elastic element 21 is, for example, a first spring. At least two first elastic elements 21 are provided, evenly distributed below the movable element 12, to ensure that the movable element 12 floats stably as a whole.
[0055] In a preferred embodiment of this application, the clutch structure includes a second elastic element 22 disposed below the sun gear 10. The sun gear 10 moves upward under the elastic action of the second elastic element 22, so that the drive tooth 14 and the driven tooth 15 mesh and engage.
[0056] In this embodiment, by providing a second elastic element 22, when the sun gear 10 is not pressed down, the second elastic element 22 can drive the sun gear 10 to move upward to ensure that the sun gear 10 reaches the position where the drive tooth 14 and the driven tooth 15 mesh, so as to ensure that the subsequent reduction mechanism can work normally and improve the reliability of the machine.
[0057] The second elastic element 22 is, for example, a second spring, in some embodiments, such as... Figure 9As shown, a second bearing 24 is embedded in the lower end of the sun gear 10. The second bearing 24 is provided with a retainer 241, which allows the second elastic element 22 to be mounted on the sun gear 10. A bracket 25 is provided below the second elastic element 22, and the lower end of the second elastic element 22 is fixed on the bracket 25. When the reduction mechanism is working, the sun gear 10, the second elastic element 22 and the bracket 25 rotate synchronously, which can avoid interference or increased noise caused by friction between the sun gear 10 and the second elastic element 22 when rotating, thereby ensuring the normal operation of the reduction mechanism.
[0058] As a preferred embodiment of this application, such as Figure 4 As shown, the upper end of the movable component 12 is provided with at least two oppositely arranged and connected push rod heads 121. The trigger part 181 is a downwardly extending trigger rib located at the bottom of the first cooking cup 18, and the trigger rib is used to press down the push rod heads 121. In this embodiment, when the first cooking cup 18 is installed, the trigger rib at its bottom can press down the push rod heads 121 in a smooth manner, so that the installation of the cup body 182 and the triggering of the deceleration mechanism are completed in one go without additional operation, thus improving the convenience of use.
[0059] In one embodiment, the trigger ribs are strip-shaped and have the same number as the push rod head 121. When at least two strip-shaped trigger ribs are used to trigger the corresponding push rod head 121, this configuration requires less material, which can save costs, and can ensure that the moving part 12 moves smoothly as a whole without deflection, thus ensuring the pressing effect of the moving part 12 on the sun gear 10.
[0060] In another embodiment, such as Figure 1 and Figure 5 As shown, the trigger rib is a ring-shaped trigger rib. When a ring-shaped trigger rib is used, regardless of the angle at which the first cooking cup 18 is installed in the circumferential direction, it can be ensured that the trigger rib can abut against the push rod head 121 and thus press down the push rod head 121. The alignment operation between the trigger rib and the push rod head 121 can be omitted, making the installation of the cup body 182 simpler and easier for the user, and improving the user experience.
[0061] In a preferred embodiment of this application, the lower end of the movable member 12 is provided with a push rod 122, which is used to press down the sun gear 10. In one embodiment, such as Figure 4 As shown, the push rod 122 is a strip-shaped push rod 122, with at least two provided and integrated through an intermediate structure. This ensures that the movable part 12 can move as a whole, simplifying the structure of the movable part 12, reducing processing materials, and saving costs while ensuring the smooth movement of the sun gear 10. In other embodiments, the push rod 122 can be an annular push rod 122. When an annular push rod 122 is used, the force exerted on the sun gear 10 by the annular push rod 122 is more balanced, promoting smooth movement of the sun gear 10 while reducing the probability of deformation due to localized force concentration, thus extending the service life of the component.
[0062] As a preferred embodiment of this application, the first cooking cup 18 includes a cup body 182 with an opening at the bottom and a cup lid 183 that closes the opening. The cup lid 183 is detachably installed on the cup body 182, and a trigger part 181 extends downward from the bottom of the cup lid 183.
[0063] like Figure 1 and Figure 5 As shown, in this embodiment, the trigger part 181 is formed on the cup lid 183. The cup lid 183 is a detachable structure. The cup lid 183 can be processed with trigger parts 181 of different shapes or distributions as needed, so that different trigger structures can be provided by replacing the cup lid 183 when needed, thereby improving the flexibility of use. Moreover, when the trigger part 181 is damaged, only the cup lid 183 needs to be replaced, which can avoid replacing the entire cooking cup and causing waste and increased costs.
[0064] like Figure 5 As shown, in this embodiment, the trigger part 181 is an annular trigger rib provided on the cup lid 183. This ensures that no matter which angle the first cooking cup 18 is installed at in the circumferential direction, the trigger rib can abut against the push rod head 121 to press down the push rod head 121. This eliminates the need for alignment between the trigger rib and the push rod head 121, making the installation of the cup body 182 simpler and easier for the user, thus improving the user experience. Furthermore, the outer peripheral wall of the trigger rib is provided with multiple spaced ribs, which can improve the overall structural strength of the cup lid 183 and prevent cracking.
[0065] In a preferred embodiment of this application, a first bearing 23 is provided on the motor shaft 131. The first bearing 23 is provided with an annular limiting part 231. The outer diameter of the annular limiting part 231 is larger than the inner diameter of the movable part 12. The annular limiting part 231 is used to restrict the upward movement of the movable part 12.
[0066] like Figure 3 As shown, in this embodiment, by limiting the upward movement of the movable part 12, it is possible to prevent the movable part 12 from dislodging from its corresponding installation position and interfering with other components when it is lifted up, ensuring that the movable part 12 floats up and down within a suitable stroke range, thereby ensuring the reliability of the movable part 12. The movable part 12 can be, for example, made of... Figure 4 In the push rod structure, the inner diameter of the movable part 12 refers to the inner diameter of the circumference formed by the multiple push rods 122 of the movable part 12.
[0067] In a preferred embodiment of this application, the trigger part 181 and the low-speed output part 17 are sequentially disposed on the radial outer side of the high-speed output part 16. The low-speed output part 17 is provided with a mounting cavity 171, and the movable part 12 is disposed in the mounting cavity 171. The mounting cavity 171 is provided with a guide post 172, and the movable part 12 moves up and down along the guide post 172.
[0068] In this embodiment, the larger internal space of the low-speed output section 17 can be used to install the movable part 12, reducing the use of the installation structure, making the internal structure of the main unit more compact, and promoting the miniaturization of the main unit; by moving the movable part 12 up and down along the guide column 172, the stability of the movement of the movable part 12 can be improved, so that the movable part 12 always maintains a stable posture, thereby ensuring the downward pressure effect of the movable part 12 on the sun gear 10.
[0069] like Figure 6 As shown, the movable component 12 includes at least two oppositely arranged and connected push rod heads 121. Each push rod head 121 has an axially oriented through hole 123, through which it moves up and down along the guide post 172. Preferably, the movable component 12 remains attached to the guide post 172 when it is lifted upwards, ensuring the reliability of its up-and-down movement along the guide post 172. A first bearing 23 is embedded in the center of the mounting cavity 171 to limit the upward movement of the movable component 12.
[0070] In one embodiment, a positioning post 173 is provided in the mounting cavity 171, and the clutch structure includes a first spring (i.e., the specific structure of the first elastic member 21) located below the movable member 12. The first spring is fixed on the positioning post 173, and the first spring is compressed when the movable member 12 moves downward.
[0071] like Figure 6 As shown, in this embodiment, the low-speed output section 17 also provides a mounting position for the first spring, which can further promote the compactness of the structural layout. Furthermore, the first spring is sleeved on the positioning post 173, ensuring that the first spring only deforms axially, avoiding radial deformation of the first spring from affecting the pushing effect on the movable part 12, and ensuring that the movable part 12 can reliably reset. Specifically, in conjunction with... Figure 3 The movable part 12 has a clearance step 124 on the radial inner side of the push rod head 121. The first spring is correspondingly set below the clearance step 124. The positioning post 173 and the guide post 172 are distributed on different circumferences. This prevents the movable part 12 from being interfered with by the surrounding structure when it moves, while also achieving a compact arrangement between structures and improving space utilization.
