[0003] In existing differential multi-drive output devices, the low-speed output connector meshes with the planetary gear and is located on the outer ring of the planetary gear. This results in an excessively large diameter of the outer ring gear of the low-speed connector, making the structure non-compact and the overall size of the device large. Furthermore, the rotation of the entire ring gear leads to inaccurate manufacturing precision, weak stress resistance, easy damage, and low output power. Utility Model Content

The middle part of the second low-speed planetary carrier extends upward to form a cylindrical body, which serves as the low-speed output interface. The form of the low-speed output interface is simple, reasonable, and easy to implement.
[0014] In an optional embodiment, the rod-shaped body has a through hole extending through both its axial ends, through which the motor shaft passes, exposing the high-speed output interface at its upper end; the rod-shaped body passes through the cylindrical body, exposing the medium-speed output interface at its upper end; the high-speed output interface, the medium-speed output interface, and the low-speed output interface form a concentric structure nested sequentially from the inside out.

The medium-speed output transmission component and the low-speed output transmission component are both housed within the internal gear, and the medium-speed planetary gear and the low-speed planetary gear mesh with the internal gear respectively. By providing the internal gear, the rotation of the medium-speed planetary gear and the low-speed planetary gear can be limited, causing them to rotate along a predetermined trajectory, thus ensuring the stability of the entire device.
[0016] In an optional embodiment, the multi-speed output device further includes a housing, in which the motor, the medium-speed output transmission assembly, and the low-speed output transmission assembly are all disposed. The internal gear is fixed to the motor housing or the housing itself.

[0036] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.
[0037] like Figures 1 to 3 As shown, this application embodiment provides a multi-speed output device 10. This multi-speed output device 10 can be used in a food processor and is capable of outputting different speeds to achieve different cooking effects depending on, for example, different ingredients.
[0038] like Figure 2 and Figure 3 As shown, the multi-speed output device 10 includes a motor 1, a medium-speed output transmission assembly 2, and a low-speed output transmission assembly 3. A motor gear 12 is fixed to the motor shaft 11 of the motor 1, and a high-speed output interface 13 is provided on the motor shaft 11. The medium-speed output transmission assembly 2 includes a medium-speed planetary gear 21 and two medium-speed planetary supports. The medium-speed planetary gear 21 is located between the two medium-speed planetary supports and meshes with the motor gear 12. The medium-speed planetary gear 21 rotates under the drive of the motor gear 12, driving the two medium-speed planetary supports to rotate synchronously. A medium-speed output interface 25 and a gear section are formed on the one of the two medium-speed planetary supports furthest from the motor 1. The low-speed output transmission assembly 3 includes a low-speed planetary gear 31 and two low-speed planetary supports. The low-speed planetary gear 31 is located between the two low-speed planetary supports and meshes with the gear section. The low-speed planetary gear 31 rotates under the drive of the gear section, driving the two low-speed planetary supports to rotate synchronously. A low-speed output interface 34 is formed on the one of the two low-speed planetary supports furthest from the motor 1.
[0039] The multi-speed output device 10 of this application embodiment has a simple structure and compact layout. The rotation radius of the medium-speed output transmission component 2 and the rotation radius of the low-speed output transmission component 3 can be designed to be small, so that the force is greater during transmission, high power output is achieved, service life is extended, and the precision of processing and manufacturing can be improved, manufacturing tolerances and noise during use can be reduced.
[0040] In some embodiments, continue to combine Figure 2 and Figure 3 The medium-speed output transmission assembly 2 includes multiple medium-speed planetary gears 21, which are arranged around the motor shaft 11 and mesh with the motor gear 12. When the motor 1 starts, the motor gear 12 drives the multiple medium-speed planetary gears 21 to rotate at the same speed. Each of the multiple medium-speed planetary gears 21 is provided with a medium-speed planetary shaft 26. The two ends of the medium-speed planetary shaft 26 are respectively engaged with two medium-speed planetary supports, thus fixing the two medium-speed planetary supports to the medium-speed planetary shaft 26 and rotating them under the drive of the medium-speed planetary shaft 26. That is, the two medium-speed planetary supports are assembled with the medium-speed planetary gears 21 through the medium-speed planetary shaft 26 to form a synchronously rotating whole.
[0041] Specifically, such as Figure 2 and Figure 3 As shown, the two medium-speed planetary carriers are a first medium-speed planetary carrier 22 and a second medium-speed planetary carrier 23. The first medium-speed planetary carrier 22 is located below the second medium-speed planetary carrier 23 and close to the motor 1. The middle part of the second medium-speed planetary carrier 23 extends upward to form a rod-shaped body 24, and the upper end of the rod-shaped body 24 forms a medium-speed output interface 25. The method of extending the rod-shaped body 24 upward from the middle of the upper second medium-speed planetary carrier 23 and forming the medium-speed output interface 25 at the upper end of the rod-shaped body 24 is simple, reasonable, and easy to manufacture.
[0042] For example, such as Figure 3 As shown, the gear portion is formed on the outer periphery of the rod-shaped body 24. By placing the gear portion and the medium-speed output interface 25 on the same rod-shaped body 24, the structure is simplified and its compactness is improved. This also facilitates the transmission of power from the medium-speed output transmission assembly 2 to the low-speed output transmission assembly 3.
[0043] The gear section can be located on the outer periphery of a segment of the rod-shaped body 24 in the axial direction, or the entire rod-shaped body 24 can be toothed. In this embodiment, multiple convex teeth are arranged along the length (axial direction) of the rod-shaped body 24, and the multiple convex teeth are evenly distributed around the outer periphery of the rod-shaped body 24 to form the gear section.
[0044] In some embodiments, the low-speed output transmission assembly 3 includes a plurality of low-speed planetary gears 31. These planetary gears 31 are arranged around the rod-shaped body 24 and mesh with the gear portion of the rod-shaped body 24. When the motor 1 starts and drives the medium-speed output transmission assembly 2 to rotate, the gear portion drives the plurality of low-speed planetary gears 31 to rotate at the same speed. Each of the plurality of low-speed planetary gears 31 is provided with a low-speed planetary shaft 35, and both ends of the low-speed planetary shaft 35 are respectively engaged with two low-speed planetary supports. This fixes the two low-speed planetary supports to the low-speed planetary shafts 35, and they rotate under the drive of the low-speed planetary shafts 35. That is, the two low-speed planetary supports are assembled with the low-speed planetary gears 31 via the low-speed planetary shafts 35 to form a synchronously rotating whole.
[0045] Specifically, such as Figure 2 and Figure 3 As shown, the two low-speed planetary carriers are a first low-speed planetary carrier 32 and a second low-speed planetary carrier 33. The first low-speed planetary carrier 32 is located below the second low-speed planetary carrier 33 and is closer to the motor 1 relative to the second low-speed planetary carrier 33. The middle part of the second low-speed planetary carrier 33 extends upward to form a cylindrical body 331. The inner wall of the cylindrical body 331, at least at the upper end, is provided with a rib-like structure to form a low-speed output interface 34. Using the cylindrical body 331 formed by extending upward from the middle of the upper second low-speed planetary carrier 33 as the low-speed output interface 34 is not only simple and reasonable in structure, but also convenient in processing and manufacturing.
[0046] The rod-shaped body 24 has through holes extending through both ends of its axial direction. The motor shaft 11 passes through the through holes, exposing the high-speed output interface 13 at its upper end. The rod-shaped body 24 passes through the cylindrical body 331, exposing the medium-speed output interface 25 at its upper end. The high-speed output interface 13, the medium-speed output interface 25, and the low-speed output interface 34 form a concentric structure nested sequentially from the inside out. The three output interfaces are located at the same end of the device and nested sequentially, further achieving a compact structure and reducing the space occupied by the device.
[0047] Understandably, both the two medium-speed planetary carriers and the two low-speed planetary carriers are provided with coaxial through holes for the motor shaft 11 to pass through, so that the high-speed output interface 13 is exposed; and the through holes on the two low-speed planetary carriers are also used for the rod-shaped body 24 to pass through, so that the medium-speed output interface 25 is exposed.
[0048] In some embodiments, such as Figure 2 and Figure 3 As shown, the multi-speed output device 10 also includes a fixedly installed internal gear 4. The medium-speed output transmission component 2 and the low-speed output transmission component 3 are both located inside the internal gear 4, and the medium-speed planetary gear 21 and the low-speed planetary gear 31 mesh with the internal gear 4 respectively. By setting the internal gear 4, the rotation of the medium-speed planetary gear 21 and the low-speed planetary gear 31 can be limited, causing them to rotate along a predetermined trajectory, thus ensuring the stability of the entire device.
[0049] In some embodiments, such as Figure 2 As shown, the multi-speed output device 10 also includes a housing 5. The motor 1, the medium-speed output transmission assembly 2, and the low-speed output transmission assembly 3 are all housed within the housing 5. An internal gear 4 is fixed to the motor housing of the motor 1 or the housing 5. In this embodiment, the internal gear 4 is fixedly connected to the motor housing. The upper end of the housing 5 has an opening 51 for exposing the high-speed output interface 13, the medium-speed output interface 25, and the low-speed output interface 34. (See [reference]). Figure 4 The high-speed output interface 13, the medium-speed output interface 25, and the low-speed output interface 34 are all constrained within the same opening 51, resulting in a neat and compact structure.
[0050] In this embodiment of the multi-speed output device 10, the first medium-speed planetary support 22, the medium-speed planetary gear 21, the second medium-speed planetary support 23, the first low-speed planetary support 32, the low-speed planetary gear 31, and the second low-speed planetary support 33 are arranged sequentially from bottom to top, forming a structure similar to a series connection. This allows the overall structure to be made smaller in the radial direction, resulting in high manufacturing precision. Moreover, since the inner gear 4 on the outer side is fixed, only the medium-speed planetary gear 21 and the low-speed planetary gear 31 on the inner side, which have a smaller diameter than the inner gear 4, rotate. This results in greater forces on both the medium-speed output transmission component 2 and the low-speed output transmission component 3, enabling not only high-power output but also extended service life.
[0051] This application also provides a food processor, such as... Figure 5 As shown, the food processor includes multiple food processing cups and a multi-speed output device 10 in any of the above embodiments. The multiple food processing cups are interchangeably mounted on the opening 51 of the multi-speed output device 10 and are respectively connected to a high-speed output interface 13, a medium-speed output interface 25, and a low-speed output interface 34. The food processor of this embodiment can output three different speeds (high, medium, and low), and its overall structure is simple and compact, with high output power and a long service life.
[0052] Continue to combine Figure 5 The blending cup system includes at least three blending cups that can be respectively adapted to the high-speed output interface 13, the medium-speed output interface 25, and the low-speed output interface 34. The three blending cups can be, for example, a juice cup 20, a vegetable chopper 30, and a juicing cup 40. The juice cup 20 is connected to the high-speed output interface 13 for blending and making juice; the vegetable chopper 30 is connected to the medium-speed output interface 25 for slicing vegetables or fruits; and the juicing cup 40 is connected to the low-speed output interface 34 for slowly juicing oranges, etc.
[0053] The food processors in this application embodiment have different output speeds, and when combined with different processing cups, they can be configured as juicers, food processors, orange juicers, meat grinders, noodle makers, etc., thus achieving diversified food processing functions.
[0054] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
