Description

Technical Field

[0001] This invention relates to the field of food processing technology, and more particularly to a food processing apparatus and a food processing machine. Background Technology

[0002] Currently, food processors such as juicers and grinders on the market generally have a grinding head, a stirring head, and a drive unit to rotate the grinding or stirring head. The drive unit usually includes a motor, or a combination of a motor and gears. If the motor directly drives the grinding head, it is difficult to control the working speed of the grinding head, making it impossible to achieve the effect of slow grinding and juicing. If a gear is used to connect the motor and then drive the grinding head, the gears and motor will occupy a large amount of structural space, resulting in an increase in the size of the product, which is inconvenient for users. For example, Chinese patent CN103705098A discloses a juicer, specifically including a base, a drive mechanism, a shell, a cover, a juicing head, and a filter structure. The drive mechanism is located in the inner cavity of the base, and the juicing head is mounted on the output end of the drive mechanism. It can be seen that the rotation speed of the juicing head is the same as the rotation speed of the motor output. Its rotation speed is singular, and the motor speed is relatively high. Without a reduction mechanism to slow down the speed, it is impossible to achieve the effect of slow grinding to make the food more fine. Summary of the Invention

[0003] To address the aforementioned technical problems in the prior art, the present invention provides a food processing device and a food processor that can reduce the speed of the rotating head through a planetary gear assembly, thereby achieving the effect of slow food processing. Furthermore, the planetary gear assembly is placed inside the receiving cavity of the rotating head, resulting in a more compact structural layout and miniaturized product size.

[0004] This invention provides a food processing apparatus, comprising:

[0005] The rotating head has a receiving cavity formed inside it;

[0006] A shaft assembly includes a drive shaft disposed within the accommodating cavity and at least one fixed shaft, both the drive shaft and the fixed shaft having one end extending out of the accommodating cavity. The drive shaft has a connecting end connected to the output shaft of a drive device, and drive teeth are formed on the drive shaft. The extended end of the fixed shaft is used to connect to a fixed structural member.

[0007] A planetary gear assembly, disposed within the accommodating cavity, includes a first planetary gear set, a first planetary carrier for mounting the first planetary gear set, and a gear ring fitted around the first planetary gear set. The first planetary gear set is kinetically connected to the drive gear section to rotate under the drive of the drive shaft. The first planetary carrier is fixedly connected to the fixed shaft. The gear ring is connected to the rotating head, so that the first planetary gear set drives the gear ring to rotate, thereby driving the rotating head connected to the gear ring to rotate. This food processing device can reduce the speed of the rotating head through the planetary gear assembly, achieving the effect of slow food processing. Furthermore, the planetary gear assembly is placed within the accommodating cavity of the rotating head, resulting in a more compact structural layout and miniaturized product size.

[0008] In some embodiments, the planetary gear assembly further includes at least one first gear set. The first gear set includes a second planet carrier and a second sun gear and a second planetary gear set that are connected in a transmission manner. The second sun gear is fixedly mounted on the second planet carrier. The first planetary gear set is mounted on the second planet carrier of the adjacent first gear set. The first planet carrier is equipped with the second planetary gear set of the adjacent first gear set, so that the first planetary gear set is mounted on the first planet carrier through the at least one first gear assembly. By setting the first gear set, the rotational speed transmitted to the rotating head can be flexibly adjusted by adjusting the transmission ratio of the first gear set.

[0009] In some embodiments, there may be one or more first gear sets. When there are multiple first gear sets, they are sequentially connected and driven along the axial direction of the transmission shaft. The above structural design is reasonable, and the rotational speed transmitted to the rotating head can be further flexibly adjusted by using multiple first gear sets.

[0010] In some embodiments, the fixed shaft and the transmission shaft are spaced apart, and the fixed shaft is positioned relative to the connecting end of the drive gear portion away from the transmission shaft. The first planetary carrier and the first planetary gear set are disposed between the fixed shaft and the transmission shaft. The above structure has a reasonable spatial layout and stable transmission.

[0011] In some embodiments, the fixed shaft is sleeved outside the drive shaft, and one end of the fixed shaft extends from the lower part of the accommodating cavity. The fixed shaft is positioned relative to the connecting end of the drive gear near the drive shaft. The first planetary carrier is sleeved outside the drive shaft, and the first planetary gear set rotates around the drive shaft. By setting the fixed shaft to be sleeved outside the drive shaft, structural stability can be increased, and the structural layout can be made more compact.

[0012] In some embodiments, there are two fixed shafts, which are nested together. One of the two fixed shafts is connected to the fixed structural member. The first planetary carrier is configured to correspond one-to-one with the fixed shafts. The first planetary gear set is used to drive the gear ring to rotate synchronously with the other of the two fixed shafts. In this way, by selecting different fixed shafts, different output speeds can be achieved, thereby realizing flexible adjustment of the output speed.

[0013] In some embodiments, the two fixed shafts are a first fixed shaft and a second fixed shaft, with the first fixed shaft sleeved around the second fixed shaft. The ends of the first and second fixed shafts near the transmission shaft are respectively connected to the first planetary carrier. The two first planetary carriers are spaced apart vertically. The planetary gear set further includes a second gear set disposed between the two first planetary carriers. The second gear set includes a third sun gear and a third planetary gear set that are connected in a transmission relationship. The third sun gear is disposed on the first planetary carrier connected to the second fixed shaft, and the third planetary gear set is disposed on the first planetary carrier connected to the first fixed shaft. The above structural layout is reasonable and provides stable transmission.

[0014] In some embodiments, the planetary gear assembly further includes a third gear set, which includes a third planet carrier and a fourth sun gear and a fourth planetary gear set that are connected in a transmission manner. The fourth sun gear is fixedly mounted on the third planet carrier, the fourth planetary gear set is mounted on a first planet carrier connected to the second fixed shaft, and the first planetary gear set is mounted on the third planet carrier, such that the first planetary gear set is mounted on the first planet carrier via the third gear set. By providing the third gear set, the rotational speed transmitted to the rotating head can be flexibly adjusted by adjusting the transmission ratio of the third gear set.

[0015] In some embodiments, the planetary gear assembly is detachably connected to the rotating head to achieve compatibility between different planetary gear assemblies and different rotating heads, so as to achieve different combinations by assembling and disassembling the planetary gear assembly.

[0016] This invention also provides a food processor, including the aforementioned food processing device. The food processor employing this device can reduce the speed of the rotating head via a planetary gear assembly, achieving a slower processing speed for ingredients. Furthermore, the planetary gear assembly is positioned within the housing cavity of the rotating head, resulting in a more compact structural layout and miniaturized product size.

[0017] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: the present invention can reduce the speed of the output shaft of the drive device by means of the first planetary gear set, the first planetary carrier and the gear ring of the planetary gear assembly, so as to achieve the effect of slow processing of food. In addition, the planetary gear assembly is placed in the receiving cavity of the rotating head and the rotating head is directly driven to rotate by the gear ring. The above structure is compact, which can reduce the size of the product and reduce the space occupied by the product. Attached Figure Description

Detailed Implementation

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This invention provides a food processing device, such as... Figures 1 to 3As shown, the food processing device includes a rotating head 1, a shaft assembly 2, and a planetary gear assembly 3. A receiving cavity 11 is formed within the rotating head 1. The shaft assembly 2 includes a drive shaft 21 and at least one fixed shaft 22 disposed within the receiving cavity 11. Both the drive shaft 21 and the fixed shaft 22 extend out of the receiving cavity 11 at one end. The drive shaft 21 has a connecting end 23 that connects to the output shaft of a drive device 71. A drive tooth 24 is formed on the drive shaft 21. The extended end of the fixed shaft 22 is used for connection to a fixed structural member. The planetary gear assembly 3 is disposed in the accommodating cavity 11. The planetary gear assembly 3 includes a first planetary gear set 31, a first planetary carrier 32 for mounting the first planetary gear set 31, and a gear ring 33 sleeved on the outside of the first planetary gear set 31. The first planetary gear set 31 is connected to the driving gear 24 for rotation under the drive of the transmission shaft 21. The first planetary carrier 32 is fixedly connected to the fixed shaft 22. The gear ring 33 is connected to the rotating head 1 so that the first planetary gear set 31 drives the gear ring 33 to rotate, thereby driving the rotating head 1 connected to the gear ring 33 to rotate.

[0041] Specifically, the aforementioned rotating head 1 can be one of the following: a stirring head or a grinding head. The stirring head requires a higher rotational speed than the grinding head.

[0042] Specifically, the drive gear 24 on the aforementioned drive shaft 21 can be understood as a first sun gear, and each star gear included in the first star gear set 31 is arranged around the first sun gear and rotates under the drive of the first sun gear. In addition, the aforementioned drive gear 24 can be integrally formed on the outer wall of the drive shaft 21.

[0043] Specifically, the aforementioned drive device 71 may include at least a drive motor, with the output shaft configured as the output end of the drive motor, and the transmission shaft 21 connected to the output shaft to drive the transmission shaft 21 to rotate via the output shaft.

[0044] Specifically, the fixed structural member connected to the aforementioned fixed shaft 22 can be understood as a fixed component. For example, a food processor using the aforementioned food processing device may include a cup lid that is fastened to the cup body. The cup lid is fixed after being fastened in place. The cup lid may be constructed as the aforementioned fixed structural member, that is, one end of the fixed shaft 22 extending out of the receiving cavity 11 may be engaged with the cup lid. The rotation of the fixed shaft 22 is limited by the cup lid, so that the fixed shaft 22 is fixed. For another example, the aforementioned cup body may be constructed as the aforementioned fixed structural member, and one end of the fixed shaft 22 extending out of the receiving cavity 11 may be engaged with the bottom of the cup body. The rotation of the fixed shaft 22 is limited by the cup body, so that the fixed shaft 22 is fixed.

[0045] Specifically, the first planetary gear set 31 can be directly mounted on the first planetary carrier 32, or it can be mounted on the first planetary carrier 32 through other structural components. The following will describe this in detail with reference to several embodiments, which will not be repeated here.

[0046] Specifically, the inner wall of the aforementioned gear ring 33 is formed with teeth that mesh with each star wheel of the first star wheel group 31, so as to realize the transmission connection between the first star wheel group 31 and the gear ring 33.

[0047] Specifically, the planetary gear assembly 3 can be understood as a reduction mechanism, which is used to transmit the rotational speed of the output shaft of the drive device 71 to the rotating head 1, and make the rotational speed of the rotating head 1 lower than the rotational speed of the output shaft. The rotational speed of the rotating head 1 can be adjusted by adjusting the transmission ratio of the planetary gear assembly 3.

[0048] Specifically, the first planetary carrier 32 can be integrally formed with the fixed shaft 22, and the first planetary carrier 32 can be formed at the end of the fixed shaft 22 near the transmission shaft 21. This can be further combined with... Figure 3 , Figure 3 The first planetary carrier 32 shown is formed at one end of the fixed shaft 22 near the drive shaft 21.

[0049] Specifically, the first star wheel assembly 31 can drive the gear ring 33 to rotate directly, or it can be connected to other structural components to indirectly drive the gear ring 33 to rotate. This will be explained in detail below with reference to several embodiments, and will not be repeated here.

[0050] The present invention can reduce the speed of the output shaft of the drive device 71 by means of the first planetary gear set 31, the first planetary carrier 32 and the gear ring 33 of the planetary gear assembly 3, so as to achieve the effect of slow processing of food. Furthermore, the planetary gear assembly 3 is placed in the receiving cavity 11 of the rotating head 1 and directly drives the rotating head 1 to rotate through the gear ring 33. The above structure is compact, which can reduce the size of the product and reduce the space occupied by the product.

[0051] Example 1

[0052] like Figures 1 to 3 As shown, the planetary gear assembly 3 adopts a single fixed shaft and a single-layer planetary gear structure, and the transmission method is a bottom-to-top sequential transmission. This bottom-to-top sequential transmission can be understood as the drive gear 24 being located below the planetary gear assembly 3, thus achieving bottom-to-top sequential transmission. The aforementioned planetary gear assembly 3 includes only a first planetary gear set 31, a first planetary carrier 32, and a fixed shaft 22. The first planetary gear set 31 is directly mounted on the first planetary carrier 32, and there is no need for any other structural components to connect the first planetary gear set 31 and the first planetary carrier 32.

[0053] In some embodiments, such as Figures 1 to 3 As shown, in Embodiment 1, the fixed shaft 22 is spaced apart from the transmission shaft 21, and the fixed shaft 22 is positioned away from the connecting end 23 of the transmission shaft 21 relative to the drive gear 24. The first planetary carrier 32 and the first planetary gear set 31 are located between the fixed shaft 22 and the transmission shaft 21. The above structure has a reasonable spatial layout and stable transmission.

[0054] Specifically, one end of the fixed shaft 22 extends from the upper part of the accommodating cavity 11.

[0055] The following description uses the clockwise rotation output of the drive shaft of the drive device 71 in Embodiment 1 as an example. Figures 1 to 3 As shown, the output shaft drives the transmission shaft 21 to rotate clockwise synchronously, and the first planetary gear set 31, which is connected to the transmission shaft 21, rotates counterclockwise under the drive of the transmission shaft 21. At this time, the first planetary carrier 32 is synchronously fixed to the fixed shaft 22. The first planetary carrier 32 will not rotate with the first planetary gear set 31, that is, the first planetary gear set 31 is fixed by the first planetary carrier 32 and cannot revolve around the sun, but can only rotate counterclockwise. Thus, the first planetary gear set 31 will drive the gear ring 33 to rotate counterclockwise synchronously, and the gear ring 33 will drive the rotating head 1 to rotate synchronously, so as to realize the rotation of the rotating head 1 through the transmission shaft 21 and the planetary gear assembly 3. It should be noted that the above synchronous rotation does not mean rotation in the same direction, but that the two components are in a follower relationship. That is, it does not limit the rotation direction of the gear ring 33 and the rotating head 1, but emphasizes that the gear ring 33 can drive the rotating head 1 to rotate. Synchronous rotation is synonymous in the following text.

[0056] Example 2

[0057] like Figure 4 and Figure 5As shown, the planetary gear assembly 3 adopts a single fixed shaft and a multi-layer planetary gear structure, and the transmission method is a bottom-up sequential transmission. This bottom-up sequential transmission can be understood as the drive gear 24 being located below the planetary gear assembly 3, thus achieving bottom-up sequential transmission. The planetary gear assembly 3 also includes at least one first gear set 4, i.e., one or more first gear sets 4. The first gear set 4 includes a second planet carrier 41 and a second sun gear 42 and a second star gear set 43 connected in transmission. The second sun gear 42 is fixedly mounted on the second planet carrier 41. The first star gear set 31 is mounted on the second planet carrier 41 adjacent to the first gear set 4. The first planet carrier 32 is mounted on the second star gear set 43 adjacent to the first gear set 4, so that the first star gear set 31 is mounted on the first planet carrier 32 through the at least one first gear set 4. By setting the first gear set 4, the speed of the transmission to the rotating head 1 can be flexibly adjusted by adjusting the transmission ratio of the first gear set 4. For example, when the rotating head 1 is a stirring head, a higher rotational speed is provided to the stirring head through the first gear set 4; when the rotating head 1 is a grinding head, a lower rotational speed is provided to the grinding head through the first gear set 4.

[0058] Specifically, the aforementioned second sun gear 42 can be integrally formed with its corresponding second planetary carrier 41.

[0059] In some embodiments, such as Figure 4 and Figure 5 As shown, when there are multiple first gear sets 4, the multiple first gear sets 4 are sequentially connected and driven along the axial direction of the transmission shaft 21. The above structural design is reasonable, and the rotational speed transmitted to the rotating head 1 can be further flexibly adjusted through multiple first gear sets 4.

[0060] Specifically, the second planetary gear set 43 is mounted on the second planetary carrier 41 or the first planetary carrier 32 of the adjacent first gear set 4. For example, as Figure 5 As shown in the figure, two first gear sets 4 are shown. The second planetary gear set 43 of the lower first gear set 4 is mounted on the second planetary carrier 41 of the upper first gear set 4, and the second planetary gear set 43 of the upper first gear set 4 is mounted on the first planetary carrier 32 above it.

[0061] In some embodiments, such as Figure 4 and Figure 5 As shown, in Embodiment 2, the fixed shaft 22 is spaced apart from the transmission shaft 21, and the fixed shaft 22 is positioned away from the connecting end 23 of the transmission shaft 21 relative to the drive gear 24. The first planetary carrier 32 and the first planetary gear set 31 are located between the fixed shaft 22 and the transmission shaft 21. The above structure has a reasonable spatial layout and stable transmission.

[0062] Specifically, one end of the fixed shaft 22 extends from the upper part of the accommodating cavity 11.

[0063] The following description uses the clockwise rotation output of the drive shaft of the drive device 71 in Embodiment 2 as an example. Figure 4 and Figure 5 As shown, the output shaft drives the transmission shaft 21 to rotate clockwise synchronously. The first planetary gear set 31, which is connected to the transmission shaft 21, rotates counterclockwise and revolves clockwise under the drive of the transmission shaft 21. Since the first planetary gear set 31 is located on the second planetary carrier 41 of the first gear set 4, which is close to it, the second planetary carrier 41 will rotate clockwise with the first planetary gear set 31, and the second sun gear 42 on the second planetary carrier 41 will drive the second planetary gear set 43 connected to it to rotate. Then, through the second planetary gear set 43, the transmission is carried upward step by step until it reaches the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32. At this time, the first planetary carrier 32 is synchronously fixed with the fixed shaft 22. The first planetary carrier 32 will not rotate with the rotation of the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32. That is, the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32, is fixed by the first planetary carrier 32 and cannot revolve around the sun, but can only rotate counterclockwise. Thus, the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32, will drive the gear ring 33 to rotate counterclockwise synchronously. The gear ring 33 will drive the rotating head 1 to rotate synchronously, so as to realize the rotation of the rotating head 1 through the transmission shaft 21 and the planetary gear assembly 3.

[0064] Example 3

[0065] like Figure 6 and Figure 7 As shown, the planetary gear assembly 3 adopts a single fixed shaft and a single-layer planetary gear structure, and the transmission method is a top-to-bottom sequential transmission. This top-to-bottom sequential transmission can be understood as the drive gear 24 being located above the planetary gear assembly 3, thereby achieving top-to-bottom sequential transmission. That is, the planetary gear assembly 3 only includes a first planetary gear set 31, a first planetary carrier 32, and a fixed shaft 22. The first planetary gear set 31 is directly mounted on the first planetary carrier 32, and there is no need for other structural components to connect the first planetary gear set 31 and the first planetary carrier 32.

[0066] In some embodiments, such as Figure 6 and Figure 7As shown, in Embodiment 3, the fixed shaft 22 is sleeved outside the transmission shaft 21, and one end of the fixed shaft 22 extends from the lower part of the accommodating cavity 11. The fixed shaft 22 is positioned relative to the drive gear 24 near the connecting end 23 of the transmission shaft 21. The first planetary carrier 32 is sleeved outside the transmission shaft 21, and the first planetary gear set 31 rotates around the transmission shaft 21. By setting the fixed shaft 22 to be sleeved outside the transmission shaft 21, the structural stability can be increased, and the structural layout is more compact.

[0067] The following description uses the clockwise rotation output of the drive shaft of the drive device 71 in Embodiment 3 as an example. Figure 6 and Figure 7 As shown, the output shaft drives the transmission shaft 21 to rotate clockwise synchronously, and the first planetary gear set 31, which is connected to the transmission shaft 21, rotates counterclockwise under the drive of the transmission shaft 21. At this time, the first planetary carrier 32 is synchronously fixed to the fixed shaft 22. The first planetary carrier 32 will not rotate with the first planetary gear set 31, that is, the first planetary gear set 31 is fixed by the first planetary carrier 32 and cannot revolve around the sun, but can only rotate counterclockwise. In this way, the first planetary gear set 31 will drive the gear ring 33 to rotate counterclockwise synchronously, and the gear ring 33 will drive the rotating head 1 to rotate synchronously, so as to realize the rotation of the rotating head 1 through the transmission shaft 21 and the planetary gear assembly 3.

[0068] Example 4

[0069] like Figure 8 and Figure 9 As shown, the planetary gear assembly 3 adopts a single fixed shaft and a multi-layer planetary gear structure, and the transmission method is a top-to-bottom sequential transmission. This top-to-bottom sequential transmission means that the drive gear 24 is located above the planetary gear assembly 3, thus achieving top-to-bottom sequential transmission. The planetary gear assembly 3 also includes at least one first gear set 4, i.e., one or more first gear sets 4. The first gear set 4 includes a second planet carrier 41 and a second sun gear 42 and a second star gear set 43 connected in transmission. The second sun gear 42 is fixedly mounted on the second planet carrier 41. The first star gear set 31 is mounted on the second planet carrier 41 of the adjacent first gear set 4. The first planet carrier 32 is equipped with the second star gear set 43 of the adjacent first gear set 4, so that the first star gear set 31 is mounted on the first planet carrier 32 through the at least one first gear set 4. By setting the first gear set 4, the speed of the transmission to the rotating head 1 can be flexibly adjusted by adjusting the transmission ratio of the first gear set 4. For example, when the rotating head 1 is a stirring head, a higher rotational speed is provided to the stirring head through the first gear set 4; when the rotating head 1 is a grinding head, a lower rotational speed is provided to the grinding head through the first gear set 4.

[0070] Specifically, the aforementioned second sun gear 42 can be integrally formed with its corresponding second planetary carrier 41.

[0071] In some embodiments, such as Figure 8 and Figure 9 As shown, when there are multiple first gear sets 4, the multiple first gear sets 4 are sequentially connected and driven along the axial direction of the transmission shaft 21. The above structural design is reasonable, and the rotational speed transmitted to the rotating head 1 can be further flexibly adjusted through multiple first gear sets 4.

[0072] Specifically, the second planetary gear set 43 is mounted on the second planetary carrier 41 or the first planetary carrier 32 of the adjacent first gear set 4. For example, as Figure 9 As shown in the figure, two first gear sets 4 are shown. The second planetary gear set 43 of the upper first gear set 4 is mounted on the second planetary carrier 41 of the lower first gear set 4, and the second planetary gear set 43 of the lower first gear set 4 is mounted on the first planetary carrier 32 below it.

[0073] In some embodiments, such as Figure 8 and Figure 9 As shown, in Embodiment 4, the fixed shaft 22 is sleeved outside the transmission shaft 21, and one end of the fixed shaft 22 extends from the lower part of the accommodating cavity 11. The fixed shaft 22 is positioned relative to the drive gear 24 near the connecting end 23 of the transmission shaft 21. The first planetary carrier 32 is sleeved outside the transmission shaft 21, and the first planetary gear set 31 rotates around the transmission shaft 21. By setting the fixed shaft 22 to be sleeved outside the transmission shaft 21, the structural stability can be increased, and the structural layout can be more compact.

[0074] The following description uses the clockwise rotation output of the drive shaft of the drive device 71 in Embodiment 4 as an example. Figure 8 and Figure 9As shown, the output shaft drives the transmission shaft 21 to rotate clockwise synchronously. The first planetary gear set 31, which is connected to the transmission shaft 21, rotates counterclockwise and revolves clockwise under the drive of the transmission shaft 21. Since the first planetary gear set 31 is located on the second planetary carrier 41 of the first gear set 4, which is close to it, the second planetary carrier 41 will rotate clockwise with the first planetary gear set 31, and the second sun gear 42 on the second planetary carrier 41 will drive the second planetary gear set 43 connected to it to rotate. Then, the transmission is passed down step by step through the second planetary gear set 43 until it is transmitted to the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32. At this time, the first planetary carrier 32 is fixed synchronously with the fixed shaft 22. The first planetary carrier 32 will not rotate with the rotation of the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32. That is, the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32, is fixed by the first planetary carrier 32 and cannot revolve around the sun, but can only rotate counterclockwise. Thus, the second planetary gear set 43 of the first gear set 4, which is close to the first planetary carrier 32, will drive the gear ring 33 to rotate counterclockwise synchronously. The gear ring 33 will drive the rotating head 1 to rotate synchronously, so as to realize the rotation of the rotating head 1 through the transmission shaft 21 and the planetary gear assembly 3.

[0075] Example 5

[0076] like Figure 10 and Figure 11 As shown, the planetary gear assembly 3 adopts a dual fixed shaft and multi-layer planetary gear structure, and the transmission method adopts a bottom-to-top sequential transmission method. The bottom-to-top sequential transmission method can be understood as the driving tooth 24 being located below the planetary gear assembly 3, thereby realizing bottom-to-top sequential transmission.

[0077] In some embodiments, such as Figure 10 and Figure 11 As shown, there are two fixed shafts 22, and the two fixed shafts 22 are nested together. One of the two fixed shafts 22 is connected to the fixed structural member. The first planetary carrier 32 is arranged in a one-to-one correspondence with the fixed shafts 22. The first planetary gear set 31 is used to drive the gear ring 33 to rotate synchronously with the other of the two fixed shafts 22. In this way, by selecting different fixed shafts 22, different output speeds can be achieved, so as to realize flexible adjustment of the output speed.

[0078] Specifically, the above-mentioned nesting relationship can be understood as one of the two fixed shafts 22 being nested outside the other fixed shaft 22. One of the two fixed shafts 22 can be selectively connected to a fixed structural member; that is, one fixed shaft 22 is connected to the fixed structural member to remain stationary, while the other fixed shaft 22 is not connected to the fixed structural member and can rotate.

[0079] In some embodiments, such as Figure 10and Figure 11 As shown, the two fixed shafts 22 are a first fixed shaft 25 and a second fixed shaft 26, respectively. The first fixed shaft 25 is sleeved on the second fixed shaft 26. The first fixed shaft 25 and the second fixed shaft 26 are respectively connected to the first planetary carrier 32 at their ends near the transmission shaft 21. The two first planetary carriers 32 are arranged vertically at intervals. The planetary gear set also includes a second gear set 5 disposed between the two first planetary carriers 32. The second gear set 5 includes a third sun gear 51 and a third planetary gear set 52 that are connected in a transmission manner. The third sun gear 51 is disposed on the first planetary carrier 32 connected to the second fixed shaft 26, and the third planetary gear set 52 is disposed on the first planetary carrier 32 connected to the first fixed shaft 25. The above structural layout is reasonable and the transmission is stable.

[0080] Specifically, when the first fixed shaft 25 is fixed, the rotating head 1 can rotate at a first speed; when the second fixed shaft 26 is fixed, the rotating head 1 can rotate at a second speed; wherein the first speed is lower than the second speed.

[0081] Specifically, each of the aforementioned fixed shafts 22 may be connected to a first planetary carrier 32 at one end near the drive shaft 21, and a third planetary gear set 52 located on the first planetary carrier 32 is mounted on one side of the first planetary carrier 32 facing the drive shaft 21.

[0082] In some embodiments, such as Figure 10 and Figure 11 As shown, the planetary gear assembly 3 further includes a third gear set 6. The third gear set 6 includes a third planet carrier 61 and a fourth sun gear 62 and a fourth star gear set 63 connected in a transmission manner. The fourth sun gear 62 is fixedly mounted on the third planet carrier 61, and the fourth star gear set 63 is mounted on a first planet carrier 32 connected to the second fixed shaft 26. The first star gear set 31 is mounted on the third planet carrier 61, so that the first star gear set 31 is mounted on the first planet carrier 32 through the third gear set 6. By setting the third gear set 6, the speed of the transmission to the rotating head 1 can be flexibly adjusted by adjusting the transmission ratio of the third gear set 6.

[0083] The following description uses the clockwise rotation output of the drive shaft of the drive device 71 in Embodiment 5 as an example. Figure 10 and Figure 11 As shown, the output shaft drives the transmission shaft 21 to rotate clockwise synchronously. The first planetary gear set 31, which is connected to the transmission shaft 21, rotates counterclockwise and revolves clockwise under the drive of the transmission shaft 21. Since the first planetary gear set 31 is located on the third planetary carrier 61 of the third gear set 6, the third planetary carrier 61 will rotate clockwise with the first planetary gear set 31, and the fourth sun gear 62 on the third planetary carrier 61 will drive the fourth planetary gear set 63 connected to it to rotate.

[0084] Furthermore, when the second fixed shaft 26 is fixed in place by the fixing structure, the first planetary carrier 32 mounted on the second fixed shaft 26 will be fixed synchronously with the second fixed shaft 26. At this time, the first fixed shaft 25 is not restricted and can rotate with the first planetary carrier 32 connected to it. The first planetary carrier 32 will not rotate with the fourth planetary gear set 63, that is, the fourth planetary gear set 63 is fixed by the first planetary carrier 32 mounted on the second fixed shaft 26 and cannot revolve around the sun, but can only rotate counterclockwise. In this way, the fourth planetary gear set 63 will drive the gear ring 33 to rotate counterclockwise synchronously, and the gear ring 33 will drive the rotating head 1 to rotate synchronously, so as to realize the rotation of the rotating head 1 through the transmission shaft 21 and the planetary gear assembly 3.

[0085] Furthermore, when the first fixed shaft 25 is fixed in place by the fixed structural members, the first planetary carrier 32 mounted on the first fixed shaft 25 will be fixed synchronously with the first fixed shaft 25. At this time, the second fixed shaft 26 is not restricted and can rotate with the first planetary carrier 32 connected to it. The fourth sun gear 62 can drive the fourth planetary gear set 63 to revolve and rotate. Driven by the revolving fourth planetary gear set 63, the first planetary carrier 32 connected to the second fixed shaft 26 will rotate with the fourth planetary gear set 63. At this time, the rotating third sun gear 51 will drive the third planetary gear set 52 to rotate. Since the third planetary gear set 52 is mounted on the first planetary carrier 32 connected to the fixed shaft 22, the third planetary gear set 52 can only rotate on its own axis and cannot revolve around the sun. Thus, the third planetary gear set 52 will drive the gear ring 33 to rotate counterclockwise synchronously, and the gear ring 33 will drive the rotating head 1 to rotate synchronously, so as to realize the rotation of the rotating head 1 through the transmission shaft 21 and the planetary gear assembly 3.

[0086] In some embodiments, such as Figures 12 to 14 As shown, the planetary gear assembly 3 is detachably connected to the rotating head 1 to achieve compatibility between different planetary gear assemblies 3 and different rotating heads 1, allowing for different combinations through the assembly and disassembly of the planetary gear assembly 3. Figure 12 The diagram shown is a schematic of the connection between the planetary gear assembly 3 and the rotating head 1 in Embodiment 2. Figure 13 The diagram shown is a schematic of the connection between the planetary gear assembly 3 and the rotating head 1 in Embodiment 5. Figure 14 The diagram shown is a schematic of the connection between the planetary gear assembly 3 and the rotating head 1 in Embodiment 4.

[0087] Specifically, the shaft assembly 2 can be assembled inside the planetary gear assembly 3, that is, the shaft assembly 2 and the planetary gear assembly 3 are assembled into a detachable module. This detachable module can be adapted to rotating heads 1 with different functions and different sizes, so as to further improve the compatibility between the planetary gear assembly 3 and the rotating head 1.

[0088] This invention also provides a food processing machine, such as... Figures 15 to 18 As shown, the food processor includes the aforementioned food processing device. The food processor employing this device, through the first planetary gear set 31, the first planetary carrier 32, and the gear ring 33 of the planetary gear assembly 3, can reduce the rotational speed of the output shaft of the drive device 71, achieving a slower processing of ingredients. Furthermore, the planetary gear assembly 3 is placed within the receiving cavity 11 of the rotating head 1, and directly drives the rotating head 1 to rotate via the gear ring 33. This compact structural layout allows for miniaturization of the product size, reducing the space occupied by the product.

[0089] In some embodiments, the food processor may further include a body 7 and a drive unit 71, a centrifugal blade 72 and a stirring blade 73 disposed thereon, with the food processing device disposed on the body 7.

[0090] Combination Figures 15 to 18 , Figure 15 The rotating head 1 shown is specifically a grinding head. Figure 16 The rotating head 1 shown is specifically a stirring head. Figure 17 This is a schematic diagram of a food processor using a centrifugal blade 72 to process food. Figure 18 This is a schematic diagram of the food processor using the mixing blade 73 to process ingredients. Thus, the aforementioned food processor can be used to process ingredients in at least the four scenarios described above, increasing its functionality.

[0091] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its scope and spirit, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
