[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 8 The illustrated detachable multi-functional food processor features a modular design, comprising a detachable base 1 and a food processor cup 2. The food processor cup 2 houses a spindle assembly 3, and the base 1 is equipped with a drive device for driving the spindle assembly 3.

[0030] The main shaft assembly 3 employs a clutch transmission structure. Specifically, the main shaft assembly 3 includes a housing 31, within which a lower half-shaft 32 and an upper half-shaft 33 are rotatably connected. The upper half-shaft 33 can also move vertically within the housing 31. The upper end of the lower half-shaft 32 is equipped with a reduction gear set 34, the output end of which is equipped with a first half-clutch 35. The lower end of the upper half-shaft 33 is equipped with a second half-clutch 36 that engages with the first half-clutch 35. An elastic return member 37 (such as a spring) is provided between the upper half-shaft 33 and the housing 31. This elastic return member 37 always elastically presses the upper half-shaft 33 upwards, keeping the first half-clutch 35 and the second half-clutch 36 disengaged. The top of the cooking cup 2 is equipped with an openable and closable top cover 4. The top cover 4 is equipped with a pressing member 41. When the top cover 4 is closed, the pressing member 41 presses the upper half-shaft 33 downwards, engaging the first half-clutch 35 and the second half-clutch 36, thus achieving power transmission. The upper shaft 33 is equipped with a working part 38 for processing food, and different functional components can be replaced as needed.

[0031] This invention features an innovative safety protection mechanism, the core of which lies in the connection method between the upper half-shaft 33 and the reduction gear set 34. Unlike the traditional direct connection method, this invention employs a unique clutch structure, achieving power transmission through the engagement of the first half-clutch 35 and the second half-clutch 36. This design offers the following significant advantages:

[0032] 1) In terms of safety, this utility model creatively combines a safety protection mechanism with the opening and closing operation of the top cover 4. Specifically, when the top cover 4 is in the open state, under the action of the elastic reset member 37 (such as a spring), the upper half-shaft 33 remains in the upper position, keeping the first half-clutch 35 and the second half-clutch 36 in a disengaged state. At this time, even if the start button is accidentally pressed, the working part 38 will not operate, fundamentally eliminating safety hazards. Only when the top cover 4 is fully closed will the pressing member 41 press down on the upper half-shaft 33, engaging the first half-clutch 35 and the second half-clutch 36 to achieve power transmission. This purely mechanical safety protection mechanism has higher reliability and a longer service life compared to traditional electronic induction switches or touch switches.

[0033] 2) In terms of structural design, this invention simplifies the complex interlocking devices found in traditional food processors. Traditional designs typically require separate sensor switches or touch switches for safety protection, which not only increases manufacturing costs but also raises the failure rate. This invention, however, cleverly integrates the safety protection function into the clutch structure, achieving necessary safety protection while simplifying the overall structure, reducing manufacturing costs and maintenance difficulty.

[0034] In addition, the safety clutch structure of this utility model also has the following characteristics:

[0035] 1. High reliability: It adopts a pure mechanical structure, is not affected by electromagnetic interference, can work stably under various environmental conditions, and has a long service life.

[0036] 2. Easy maintenance: The entire safety protection mechanism adopts a modular design, which is easy to disassemble and maintain.

[0037] 3. High cost-effectiveness: It eliminates the need for traditional electronic sensing devices, reducing material costs and assembly difficulty.

[0038] In summary, this utility model achieves a higher level of safety protection through an innovative safety clutch structure design, while simplifying the structure, reducing costs, and improving reliability.

[0039] Furthermore, the reduction gear set 34 is a planetary gear set, including a ring gear 341, a sun gear 342, multiple planet gears 343, and a planet carrier 344. The ring gear 341 is disposed inside the housing 31, the sun gear 342 is fixedly connected to the upper end of the lower half-shaft 32, and the planet carrier 344 is fixedly connected to the first half-clutch 35. This planetary gear set is mainly used for speed reduction and torque increase, and also makes the overall structure more compact.

[0040] Furthermore, the main shaft assembly 3 is detachably connected inside the blending cup 2, facilitating disassembly, cleaning, and maintenance.

[0041] More specifically, the bottom surface of the cooking cup 2 has an upwardly extending outer sleeve 21, and the top surface of the housing 31 has an upwardly extending inner sleeve 311 that covers the upper half-shaft 33. The inner sleeve 311 is inserted into the outer sleeve 21 from bottom to top, and a snap-fit ​​structure 22 is provided between the bottom surface of the cooking cup 2 and the housing 31. The snap-fit ​​structure 22 specifically includes an L-shaped buckle 221 on the bottom surface of the cooking cup 2 and a boss 222 on the outer surface of the housing 31. The boss 222 can be snapped into the buckle 221, which facilitates assembly and disassembly.

[0042] Furthermore, the pressing member 41 is a pin located in the middle of the inner top surface of the top cover 4, and the upper end face of the upper half shaft 33 is provided with a tapered groove 331 for the lower end of the pin to be inserted. This design ensures the accuracy and reliability of the pressing process.

[0043] Preferably, a bearing is provided between the top pressing member 41 and the top cover 4 for rotatably connecting the two, so that the top pressing member 41 can rotate relative to the top cover 4, thereby reducing frictional loss.

[0044] Furthermore, the drive device includes a drive motor housed within the base 1, with a third half-clutch 11 mounted on the output shaft of the drive motor, and a fourth half-clutch 321 at the lower end of the lower half-shaft 32 that engages with the third half-clutch 11. This clutch structure design makes it easier to assemble and disassemble the base 1 and the food processor 2, while ensuring the reliability of power transmission.

[0045] Preferably, the first half-clutch 35 and the second half-clutch 36 are each provided with a plurality of meshing teeth, the two sides of which are a plane and an inclined plane, respectively, that is, spiral right-angled triangular teeth. This design not only improves the meshing reliability of the clutch, but also reduces the impact during engagement and extends the service life. Similarly, the third half-clutch 11 and the fourth half-clutch 321 are each provided with a plurality of meshing teeth, the two sides of which are a plane and an inclined plane, respectively.

[0046] Furthermore, different working parts 38, such as stirring blades, can be installed on the upper shaft 33 as needed. Figure 8 Example 2 shown), slicing blade or shredder disc (such as...) Figure 4 , Figure 6 The first embodiment shown here enables multiple food processing functions.
