[0002] Currently, the mixing method of cooking machines is generally to break up the ingredients in the pot by rotating the mixing claws. This simple mixing method makes it difficult for the ingredients to be fully mixed, resulting in poor mixing and stir-frying effects. This can easily lead to uneven heating of the ingredients in the pot, which in turn leads to a decline in the taste of the dish. Utility Model Content

[0008] Furthermore, at least one power receiving tooth and one power output tooth are movably arranged relative to the tooth structure and are capable of changing their meshing position with the tooth structure to change the direction of rotation.

[0009] Furthermore, the drive assembly has a power output shaft, wherein the rotation centers of at least one power receiving tooth and power output tooth coincide with the axis of the power output shaft; or the rotation centers of at least one power receiving tooth and power output tooth intersect with the axis of the power output shaft.

[0010] Furthermore, the rotation centers of the power receiving tooth and the power output tooth intersect the axis of the power output shaft, wherein at least one power receiving tooth and the power output tooth are located on both sides of the extended axis of the power output shaft; or at least one power receiving tooth and the power output tooth are simultaneously located on one side of the extended axis of the power output shaft.

[0012] Furthermore, both the drive output unit and the power receiving tooth mesh with the first toothed structure, and the power output tooth meshes with the second toothed structure. The drive output unit drives the rotating outer shell to rotate through the first toothed structure, which in turn drives the power receiving tooth and the power output tooth to rotate synchronously. The power output tooth drives the second toothed structure to rotate the stirring shovel assembly. Alternatively, both the drive output unit and the power receiving tooth mesh with the second toothed structure, and the power output tooth meshes with the first toothed structure.

At this time, the rotating component can rotate as a whole under the action of the driving force. Since the stirring spatula component is set on the rotating component, it rotates together with the rotating component, realizing the revolution of the stirring spatula component.

[0034] To address the problem of poor food mixing performance in existing technologies, this invention provides a cooking mixing mechanism and a cooking appliance.

[0035] Example 1

[0036] like Figures 1 to 4The cooking mixing mechanism shown includes a rotating component 10, a stirring spatula assembly 20, a driving component 30, and an intermediate component 40. The rotating component 10 has a rotating housing 11 and at least one toothed structure. The stirring spatula assembly 20 is movably connected to the rotating housing 11, and the rotating housing 11 drives the stirring spatula assembly 20 to rotate. The driving component 30 has a driving output section 31, which drives the rotating housing 11 to rotate. The intermediate component 40 is disposed close to the driving component 30 and the rotating component 10, and the intermediate component 40 transmits the driving force of the driving output section 31 to at least one toothed structure, thereby driving the stirring spatula assembly 20 or the rotating housing 11 to rotate.

[0037] In this embodiment, an intermediate component 40 is provided. According to the transmission relationship, the intermediate component 40 is located between the driving component 30 and the rotating component 10, so that the driving force of the driving component 30 can be transmitted to the toothed structure of the rotating component 10 through the intermediate component 40. At this time, the rotating component 10 can rotate as a whole under the action of the driving force. Since the stirring spatula component 20 is located on the rotating component 10, the stirring spatula component 20 rotates together with the rotating component 10, realizing the revolution of the stirring spatula component 20. At the same time, since the stirring spatula component 20 and the rotating component 10 are movably connected, the stirring spatula component 20 can also rotate relative to the rotating component 10. The two aspects work together so that the rotating component 10 drives the stirring spatula component 20 to revolve while the stirring spatula component 20 can also rotate, so that the cooking utensils can perform multiple stirring forms at the same time, improve the coverage of the stirring trajectory, and the ingredients can be thoroughly stirred. The effect of breaking up and stir-frying the ingredients is better, and the quality of the cooked dishes is higher.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, there are multiple toothed structures. This embodiment uses two toothed structures as an example, specifically including a first toothed structure 12 and a second toothed structure 13. The first toothed structure 12 is connected to the rotating outer shell 11, and the second toothed structure 13 is connected to the stirring spatula assembly 20. Thus, the driving force of the driving assembly 30 can be directly or indirectly transmitted to the first toothed structure 12, thereby causing the rotating outer shell 11 to rotate. This causes the rotating assembly 10 to drive the stirring spatula assembly 20 to revolve around the axis of the rotating outer shell 11. Simultaneously, the driving force can also be directly or indirectly transmitted to the second toothed structure 13, thereby causing the stirring spatula assembly 20 to rotate around its own axis. These two aspects cooperate to allow the stirring spatula assembly 20 to simultaneously revolve and rotate, thereby improving the stirring effect. Of course, the number of toothed structures can be adjusted as needed, and is not limited to the two configurations in this embodiment; more toothed structures can also be used.

[0039] In this embodiment, the overall drive transmission trajectory is as follows: the drive output unit 31 drives the second toothed structure 13 to rotate, causing the stirring shovel assembly 20 to rotate. At the same time, the drive output unit 31 also drives the intermediate component 40 to move. The drive output unit 31 transmits the driving force to the first toothed structure 12 through the intermediate component 40, thereby realizing the revolution of the stirring shovel assembly 20.

[0040] Of course, the first toothed structure 12 and the second toothed structure 13 mentioned above can be interchanged. That is, the drive output unit 31 drives the first toothed structure 12 to rotate, so that the stirring shovel assembly 20 revolves. At the same time, the drive output unit 31 also drives the intermediate part 40 to move. The drive output unit 31 transmits the driving force to the second toothed structure 13 through the intermediate part 40, thereby realizing the rotation of the stirring shovel assembly 20.

[0041] like Figure 2 As shown, in this embodiment, the intermediate component 40 includes at least one power receiving tooth 41 and at least one power output tooth 42. The power receiving tooth 41 meshes with the toothed structure or drive output part 31, receiving the driving force from the toothed structure or drive output part 31, and outputting the driving force through the power output tooth 42. This embodiment uses one power receiving tooth 41 and one power output tooth 42 as an example for illustration; of course, the number can be increased accordingly as needed. The transmission between the power receiving tooth 41 and the power output tooth 42 can be achieved through direct connection, meshing, or indirect transmission by adding components between them. The power receiving tooth 41 and the power output tooth 42 realize the reception and transmission of power, thereby achieving the transmission of driving force.

[0042] In this embodiment, the power receiving tooth 41 and the power output tooth 42 do not employ direct transmission. Instead, indirect transmission is achieved through other components. Specifically, the intermediate component 40 in this embodiment also includes a drive shaft 43. Both the power receiving tooth 41 and the power output tooth 42 are circumferentially fixedly sleeved on the drive shaft 43. The power receiving tooth 41, the power output tooth 42, and the drive shaft 43 can be connected via an interference fit or by welding, allowing the power receiving tooth 41, the power output tooth 42, and the drive shaft 43 to rotate synchronously. When the power receiving tooth 41 receives driving force, it drives the drive shaft 43 to rotate, which in turn drives the power output tooth 42 to rotate, thus achieving the effect of the intermediate component 40 transmitting driving force.

[0043] In this embodiment, the drive output unit 31 adopts a gear structure, and the gear and the tooth structure are meshed together. The drive assembly 30 also has a power output shaft 32, and the drive output unit 31 is sleeved on the outside of the power output shaft 32 and rotates together under the drive of the power output shaft 32, thereby realizing the output of driving force. In this embodiment, the rotation centers of the power receiving teeth 41 and the power output teeth 42 intersect with the axis of the power output shaft 32. Since the power receiving teeth 41 and the power output teeth 42 are both sleeved on the transmission shaft 43, the rotation centers of the power receiving teeth 41 and the power output teeth 42 are essentially the rotation centers of the transmission shaft 43, that is, the axis of the transmission shaft 43. Therefore, the above arrangement means that the axis of the transmission shaft 43 and the axis of the power output shaft 32 are not parallel. In this embodiment, it is preferable that they are perpendicular. In this way, the positions of the power receiving teeth 41 and the power output teeth 42 can be staggered from the position of the drive output unit 31, avoiding interference between them, and at the same time helping to reduce the space between components and make the structure more compact.

[0044] Based on the above structural form, the specific cooperation between the rotating assembly 10, the driving assembly 30, and the intermediate component 40 in this embodiment is as follows: the driving output part 31 simultaneously meshes with the power receiving tooth 41 and the second toothed structure 13, and the first toothed structure 12 meshes with the power output tooth 42. In this way, the driving output part 31 drives the second toothed structure 13 to rotate, causing the second toothed structure 13 to drive the stirring shovel assembly 20 to rotate. At the same time, the driving output part 31 drives the power receiving tooth 41, which in turn drives the transmission shaft 43 and the power output tooth 42 to rotate. The power output tooth 42 drives the first toothed structure 12 to rotate, thereby realizing that the driving output part 31 drives the first toothed structure 12 to rotate through the intermediate component 40, causing the rotating shell 11 to drive the stirring shovel assembly 20 to revolve.

[0045] In this embodiment, the power receiving tooth 41 and the power output tooth 42 are movably configured relative to the toothed structure. This allows the power receiving tooth 41 and the power output tooth 42 to independently change their meshing positions with the toothed structure, thereby adjusting the revolution and rotation directions of the stirring shovel assembly 20. The revolution and rotation directions of the stirring shovel assembly 20 can be the same or opposite. Since both the power receiving tooth 41 and the power output tooth 42 are mounted on the drive shaft 43, they are not completely fixed relative to the drive shaft 43. Both the power receiving tooth 41 and the power output tooth 42 can move along the axial direction of the drive shaft 43, thereby changing their meshing positions with the corresponding toothed structure. This allows adjustment of the rotation direction during the transmission of driving force, thus achieving adjustment of the rotation and revolution directions.

[0046] Since the rotation centers of the power receiving tooth 41 and the power output tooth 42 in this embodiment intersect with the axis of the power output shaft 32, the power receiving tooth 41 and the power output tooth 42 are respectively located on both sides of the extended axis of the power output shaft 32. Based on the above-mentioned axially adjustable position setting, it is necessary to ensure that both the power receiving tooth 41 and the power output tooth 42 can rotate synchronously with the transmission shaft 43 and move axially. In this case, there are various specific structural configurations. For example, the transmission shaft 43 can be a non-circular cross-section shaft, and the inner rings of the power receiving tooth 41 and the power output tooth 42 can match the shape of the transmission shaft 43. Of course, the above configuration can also be adjusted as needed and is not limited to the configuration of this embodiment. Furthermore, since the number of power receiving teeth 41 and power output teeth 42 can be increased as needed, multiple positional relationships can coexist when multiple power receiving teeth 41 or power output teeth 42 are provided.

[0047] In this embodiment, the rotating outer shell 11 is sleeve-shaped, with an installation space formed in its middle. A part of the stirring spatula assembly 20 and the second toothed structure 13 are both disposed within the installation space. A first toothed structure 12 is provided on the end face of the rotating outer shell 11, so that the first toothed structure 12 and the second toothed structure 13 are located at the same end of the rotating outer shell 11. In this embodiment, the first toothed structure 12 does not use a separate gear, but only has teeth provided on the end face of the rotating outer shell 11, forming the first toothed structure 12. In this embodiment, the second toothed structure 13 uses a gear, which is disposed inside the first toothed structure 12. The drive output part 31 and the intermediate part 40 are also disposed at this position, so that the drive output part 31, the intermediate part 40, the first toothed structure 12, and the second toothed structure 13 can achieve transmission and cooperation. The axes of the power output shaft 32, the transmission shaft 43, and the second tooth structure 13 are perpendicular to each other. Since the mixing shovel assembly 20 is generally arranged longitudinally, the axis of the second tooth structure 13 is also arranged longitudinally. The axes of the power output shaft 32 and the transmission shaft 43 are arranged transversely, thereby realizing the meshing and transmission between the above components.

[0048] The cooking appliance in this embodiment also includes a mounting bracket. The rotating housing 11 is rotatably mounted on the mounting bracket. A longitudinally extending connecting arm is provided on the mounting bracket. The connecting arm is located on opposite sides of the rotating housing 11 and protrudes upwards from the upper surface of the rotating housing 11 by a certain distance. The two ends of the drive shaft 43 are tractably mounted on the two extending arms, allowing the drive shaft 43 to be rotatably mounted above the rotating housing 11. This allows the power receiving tooth 41 and the power output tooth 42 to be positioned above the rotating housing 11, achieving meshing with the first tooth structure 12 and the second tooth structure 13 on the upper surface of the rotating housing 11. Of course, the specific positional relationship between the rotating housing 11, the second tooth structure 13, the drive output part 31, and other components in this embodiment is not limited to the arrangement described above. The positions can be adjusted as needed, as long as the transmission and engagement relationship described above can be achieved.

[0049] In this embodiment, the rotating outer shell 11 has a first axis of rotation, and the stirring spatula assembly 20 includes a stirring spatula 23 rotatably mounted on the rotating outer shell 11. The stirring spatula 23 has a second axis of rotation relative to the rotating outer shell 11. Since the bottom surface of the cooking vessel is usually curved, an angle is formed between the first axis of rotation and the second axis of rotation in this embodiment. Taking the first axis of rotation as longitudinal as an example, the second axis of rotation forms an angle greater than 0 degrees and less than 90 degrees with the first axis of rotation, thereby adapting the structure of the stirring spatula assembly 20 to the design of the bottom surface of the pot, further improving the stirring effect of the ingredients.

[0050] The specific structural form of the stirring spatula assembly 20 can be set as needed. It can be directly set as a rod-shaped stirring spatula 23, with gears or teeth at its end to form stirring spatula teeth 231. For example... Figure 3As shown, to further improve the stirring effect, the stirring spatula assembly 20 of this embodiment includes a central shaft 21, stirring output teeth 22, and at least one stirring spatula 23. At least one toothed structure is located on the end face of the central shaft 21; specifically, a second toothed structure 13 is sleeved on the end of the central shaft 21 facing the drive assembly 30. Thus, the central shaft 21 and the second toothed structure 13 are associated, and when the second toothed structure 13 is driven, it causes the central shaft 21 to rotate together. The stirring output teeth 22 are located at the end of the central shaft 21 away from the toothed structure and rotate synchronously with the central shaft 21. Since the second toothed structure 13 in this embodiment is located at the top of the central shaft 21, the stirring output teeth 22 are located at the bottom of the central shaft 21. The stirring shovel 23 is rotatably mounted on the rotating housing 11. The stirring shovel 23 has stirring shovel teeth 231, which extend into the rotating housing 11 and mesh with the stirring output teeth 22. Thus, due to the connection between the stirring shovel 23 and the rotating housing 11, the rotating housing 11 can drive the stirring shovel 23 to rotate together. At the same time, when the central shaft 21 rotates, the central shaft 21 transmits driving force through the stirring output teeth 22 and the stirring shovel teeth 231, thereby driving the stirring shovel 23 to rotate around its own axis relative to the rotating housing 11, thus realizing the rotation of the stirring shovel 23.

[0051] In this embodiment, multiple stirring shovels 23 are preferably provided, and each stirring shovel 23 is arranged at intervals along the circumference of the rotating outer shell 11. Taking three stirring shovels 23 as an example, the three stirring shovels 23 are arranged at 120-degree intervals along the circumference of the rotating outer shell 11. The three stirring shovels 23 cooperate with the central shaft 21 and the stirring output teeth 22 on it. The stirring shovels 23 extend downward at an angle away from the axis of the central shaft 21, thereby improving the stirring effect.

[0052] In this embodiment, the stirring output tooth 22 is configured as a gear-shaped structure. Thus, the stirring output tooth 22 is an external gear ring structure with external teeth. The external teeth mesh with the stirring shovel tooth 231. At this time, the inner part of the stirring shovel tooth 231, which is close to the central shaft 21, meshes with the external teeth. As a result, when the rotating shell 11 drives the stirring shovel 23 to rotate, the stirring shovel tooth 231 rotates due to its meshing with the stirring output tooth 22, and the revolution direction and rotation direction of the stirring shovel 23 are the same.

[0053] When there are multiple stirring shovels 23, there can be only one stirring output tooth 22 with its outer teeth distributed circumferentially, so that the stirring shovel teeth 231 of multiple stirring shovels 23 can simultaneously mesh with the outer teeth of the stirring output tooth 22 at different positions, achieving the effect of one stirring output tooth 22 driving multiple stirring shovels 23 to rotate at the same time.

[0054] Besides the aforementioned external gear ring structure, the stirring output tooth 22 can also adopt an internal gear ring structure. Specifically, the stirring output tooth 22 adopts a U-shaped structure, forming a downward-facing receiving area. The inner wall of the receiving area has internal teeth, thus making the stirring output tooth 22 an internal gear ring structure. The end of the stirring shovel 23 extends into the receiving area, so that the stirring shovel tooth 231 is located within the receiving area. The side of the stirring shovel tooth 231 away from the central axis 21, that is, the outer part, meshes with the internal teeth, while the inner part of the stirring shovel tooth 231 near the central axis 21 leaves a gap with the central axis 21, thereby avoiding interference and collision. It should be noted that since the stirring shovel 23 rotates continuously during rotation, the outer part of the stirring shovel tooth 231 mentioned here is not a fixed part, but changes continuously with the rotation of the stirring shovel 23. Through the above arrangement, the rotation direction of the stirring shovel 23 is opposite to the revolution direction, thereby making the stirring more thorough and the stirring effect better.

[0055] like Figure 4 As shown, the stirring spatula 23 in this embodiment includes a first rod portion 232, a second rod portion 233, an elastic element 234, and a scraper element 235. The first rod portion 232 is in a driving engagement with the stirring output teeth 22. One end of the first rod portion 232 extends into the rotating outer shell 11, and its end is provided with stirring spatula teeth 231, thereby achieving meshing with the stirring output teeth 22. The second rod portion 233 is movably connected to the first rod portion 232. In this embodiment, the first rod portion 232 and the second rod portion 233 are arranged in a sleeve configuration, meaning one of the first rod portion 232 and the second rod portion 233 has a sleeve structure, and the other has a rod-shaped structure. The rod-shaped structure extends into the sleeve structure and can move axially within the sleeve structure. This allows the relative position between the first rod portion 232 and the second rod portion 233 to be adjusted, thereby adjusting the overall length of the stirring spatula 23, ensuring a tight fit between the stirring spatula 23 and the inner wall of the pot, thus improving the stirring effect. Meanwhile, in this embodiment, an elastic element 234 is provided between the first rod portion 232 and the second rod portion 233. The elastic element 234 can be a spring or other components. The two ends of the elastic element 234 abut against the first rod portion 232 and the second rod portion 233 respectively, thereby providing the second rod portion 233 with an elastic force to move away from the first rod portion 232, so that the stirring spatula 23 has a tendency to increase in overall length. The scraper 235 is connected to the second rod portion 233. The scraper 235 is a component that fits against the inner wall of the pot to scrape the pot. The specific material of the scraper 235 can be set as needed. Under the action of the elastic element 234, the scraper 235 remains against the inner wall of the pot, thereby ensuring a good scraping and stirring effect.

[0056] It should be noted that the relationship between the rotation direction and the revolution direction of the stirring shovel assembly 20 is not determined by a single set of gears, but by the meshing relationship between multiple sets of gears on the transmission path. This includes not only the direction of the rotational driving force transmitted between the drive output part 31, the intermediate part 40 and the tooth structure, but also the direction of the rotational driving force transmitted between the stirring output teeth 22 and the stirring shovel 23. These aspects work together to adjust the relationship between the rotation direction and the revolution direction.

[0057] This embodiment also provides a cooking appliance, including the cooking stirring mechanism described above. Elastic buffers can be provided between the gears in the cooking stirring mechanism, such as between the drive output part 31 and the second tooth structure 13, between the drive output part 31 and the power receiving tooth 41, and between the first tooth structure 12 and the power output tooth 42. The elastic buffers can prevent rigid contact between the teeth from causing easy wear and extend the service life.

[0059] The difference from Embodiment 1 is that the cooperation between the drive component 30, the rotation component 10, and the intermediate component 40 is different.

[0060] like Figure 5 As shown, in this embodiment, the drive output unit 31 drives the first tooth structure 12 to rotate, and the first tooth structure 12 transmits the driving force to the second tooth structure 13 through the intermediate member 40.

[0061] Specifically, the structural form of the components in this embodiment is basically the same as that in Embodiment 1, but the specific transmission route is different. The intermediate component 40 in this embodiment still includes a power receiving tooth 41, a power output tooth 42, and a transmission shaft 43, and the axis of the transmission shaft 43 is still perpendicular to the power output shaft 32. The power receiving tooth 41 and the power output tooth 42 are located on both sides of the extended axis of the power output shaft 32. However, in this embodiment, both the drive output part 31 and the power receiving tooth 41 are engaged with the first tooth structure 12, while the power output tooth 42 is engaged with the second tooth structure 13. In this way, the driving force of the drive output part 31 is transmitted to the rotating housing 11 through the first tooth structure 12, thereby driving the rotating housing 11 to rotate and realize the revolution of the stirring shovel assembly 20. At the same time, the driving force of the first tooth structure 12 is transmitted to the second tooth structure 13 in sequence through the power receiving tooth 41, the transmission shaft 43, and the power output tooth 42, driving the power receiving tooth 41 and the power output tooth 42 to rotate synchronously, and driving the stirring shovel assembly 20 to rotate on its own axis through the second tooth structure 13. In this way, the two parts work together to achieve the revolution and rotation of the mixing shovel assembly 20.

[0062] It should be noted that the meshing relationships between the power receiving tooth 41 and the power output tooth 42 and the first tooth structure 12 and the second tooth structure 13 can be interchanged. That is, both the drive output part 31 and the power receiving tooth 41 mesh with the second tooth structure 13, while the power output tooth 42 meshes with the first tooth structure 12. In this way, the drive output part 31 drives the second tooth structure 13 to rotate, thereby realizing the rotation of the stirring shovel assembly 20. At the same time, the second tooth structure 13 drives the power receiving tooth 41 and the power output tooth 42 to rotate synchronously, thereby transmitting the driving force to the first tooth structure 12 through the intermediate part 40. The power output tooth 42 drives the rotating outer shell 11 to rotate through the first tooth structure 12, thereby realizing the revolution of the stirring shovel assembly 20.

[0063] Example 3

[0064] The difference from Embodiment 2 is that the positional relationship between the power receiving tooth 41 and the power output tooth 42 on the transmission shaft 43 is different in this embodiment.

[0065] like Figure 6 As shown, specifically, in this embodiment, both the power receiving tooth 41 and the power output tooth 42 are located on one side of the extended axis of the power output shaft 32, so that they mesh with the first tooth structure 12 and the second tooth structure 13 facing the same side. Compared with the arrangement in Embodiment 2, while keeping other gear meshing methods unchanged, this embodiment changes the relative positions of the power receiving tooth 41 and the power output tooth 42, thereby changing the rotation direction of the stirring spatula assembly 20. If the rotation direction and the revolution direction of the stirring spatula assembly 20 in Embodiment 2 are the same, then the rotation direction and the revolution direction of the stirring spatula assembly 20 in this embodiment are opposite; if the rotation direction and the revolution direction of the stirring spatula assembly 20 in Embodiment 2 are opposite, then the rotation direction and the revolution direction of the stirring spatula assembly 20 in this embodiment are the same. This achieves the adjustment of the rotation direction and the revolution direction of the stirring spatula assembly 20, making the stirring effect of the stirring spatula assembly 20 more in line with cooking needs.

[0066] It should be noted that the configuration method in this embodiment can also be used in other embodiments, not limited to Embodiment 2.

[0067] Example 4

[0068] The difference from Embodiment 2 is that the positional relationship between the rotation center of the power receiving tooth 41 and the power output tooth 42 and the axis of the power output shaft 32 is different in this embodiment.

[0069] like Figures 7 to 11As shown, in this embodiment, the rotation centers of the power receiving gear 41 and the power output gear 42 are no longer intersecting with the axis of the power output shaft 32, but rather coincident. That is, the axis of the transmission shaft 43 coincides with the axis of the power output shaft 32, and they can be directly connected to form a single shaft structure. Alternatively, a coupling can be installed between them, allowing the power output shaft 32 to directly drive the transmission shaft 43 to rotate. In this embodiment, the power output shaft 32 and the transmission shaft 43 from Embodiment 2 are integrally formed into a single power output shaft 32, thus simplifying the structure.

[0070] In this embodiment, the drive output part 31, the power receiving tooth 41, and the power output tooth 42 are all sleeved on the power output shaft 32. However, unlike the arrangement in Embodiment 2, in this embodiment, the drive output part 31 is fixedly sleeved on the power output shaft 32, while the power receiving tooth 41 and the power output tooth 42 are rotatably sleeved on the power output shaft 32. Furthermore, the power receiving tooth 41 and the power output tooth 42 are connected together, so that the power receiving tooth 41 and the power output tooth 42 rotate synchronously. In this way, the power output shaft 32 can drive the drive output part 31 to rotate. The driving force of the drive output part 31 is transmitted to the first toothed structure 12, thereby driving the rotating outer shell 11 to rotate, realizing the revolution of the stirring shovel assembly 20. At the same time, the driving force of the first toothed structure 12 is transmitted to the power receiving tooth 41, thereby driving the power receiving tooth 41 and the power output tooth 42 to rotate synchronously. The power output tooth 42 transmits the driving force to the second toothed structure 13, thereby driving the stirring shovel assembly 20 to rotate, making the stirring shovel assembly 20 rotate on its own axis. In this way, the stirring shovel assembly 20 can simultaneously revolve around the sun and rotate on its own axis.

[0071] Of course, similar to Embodiment 2, the meshing relationship between the power receiving tooth 41 and the power output tooth 42 and the first tooth structure 12 and the second tooth structure 13 described above in this embodiment can also be interchanged. After the interchange, the driving force of the drive output part 31 is first transmitted to the second tooth structure 13, causing the stirring shovel assembly 20 to rotate. At the same time, the driving force is transmitted to the first tooth structure 12 through the second tooth structure 13, the power receiving tooth 41, and the power output tooth 42, causing the rotating outer shell 11 to rotate, thus realizing the revolution of the stirring shovel assembly 20. Further details will not be elaborated further.

[0072] In this embodiment, the power receiving tooth 41 and the power output tooth 42 can both be located on one side of the extended axis of the central shaft 21, that is... Figure 8 and Figure 9The arrangement shown is as follows. Alternatively, the power receiving tooth 41 and the power output tooth 42 can also be located on opposite sides of the extended axis of the central shaft 21, i.e. Figure 10 and Figure 11 The two settings shown will change the relationship between the revolution direction and the rotation direction of the mixing spatula assembly 20.

[0073] Example 5

[0074] The difference from Embodiment 1 is that the cooperation between the drive component 30, the rotation component 10, and the intermediate component 40 is different.

[0075] In this embodiment, the drive output unit 31 drives the intermediate component 40 to rotate, and the intermediate component 40 drives the first tooth structure 12 and the second tooth structure 13 to rotate respectively.

[0076] Specifically, in this embodiment, there is no direct driving relationship between the drive output unit 31 and the first toothed structure 12 and the second toothed structure 13. Instead, they are all driven through the intermediate component 40. Taking the engagement of the power receiving tooth 41 with the second toothed structure 13 and the power output tooth 42 with the first toothed structure 12 as an example, the drive output unit 31 engages with the power receiving tooth 41, the power receiving tooth 41 engages with the second toothed structure 13, and the power output tooth 42 engages with the first toothed structure 12. In this way, the driving force of the drive output unit 31 is transmitted to the second toothed structure 13 through the power receiving tooth 41, and the second toothed structure 13 drives the stirring shovel assembly 20 to rotate. At the same time, the driving force of the drive output unit 31 is also transmitted to the first toothed structure 12 in sequence through the power receiving tooth 41, the transmission shaft 43, and the power output tooth 42, and the first toothed structure 12 drives the rotating shell 11 to rotate, so that the stirring shovel assembly 20 revolves. In this way, the mixing shovel assembly 20 can simultaneously revolve around the sun and rotate on its own axis.

[0077] It should be noted that the arrangement in Embodiment 3, in which both the power receiving tooth 41 and the power output tooth 42 are located on one side of the axis extension line of the power output shaft 32, is also applicable to this embodiment.

[0078] Example 6

[0079] This embodiment combines the arrangement in Embodiment 4 where the axis of the transmission shaft 43 coincides with the axis of the power output shaft 32 with the transmission method in Embodiment 5 where the drive output unit 31 drives the intermediate component 40 to rotate, and the intermediate component 40 drives the first tooth structure 12 and the second tooth structure 13 to rotate.

[0080] In this embodiment, the axis of the transmission shaft 43 coincides with the axis of the power output shaft 32 in Embodiment 2, and the two form a single power output shaft 32. However, in this embodiment, the drive output part 31 does not mesh with either the first tooth structure 12 or the second tooth structure 13. In addition to fixing the drive output part 31 on the power output shaft 32, at least one of the power receiving tooth 41 and the power output tooth 42 is also fixedly fixed on the power output shaft 32. When only one of the power receiving tooth 41 and the power output tooth 42 is fixedly fixed on the power output shaft 32, the power receiving tooth 41 and the power output tooth 42 remain connected. When both the power receiving tooth 41 and the power output tooth 42 are fixedly fixed on the power output shaft 32, the power receiving tooth 41 and the power output tooth 42 do not need to be connected. In this way, the driving force of the drive output unit 31 is transmitted to the power receiving tooth 41 and the power output tooth 42 through the power output shaft 32. Then, the power receiving tooth 41 and the power output tooth 42 drive the first tooth structure 12 and the second tooth structure 13 to rotate, thereby realizing the rotation of the rotating shell 11 driving the stirring shovel assembly 20 to revolve and the stirring shovel assembly 20 to rotate on its own axis.

[0081] Similarly, the meshing relationship between the power receiving tooth 41 and the power output tooth 42 and the first tooth structure 12 and the second tooth structure 13 can be interchanged, which will not be elaborated here.

[0082] Example 7

[0083] The difference from Embodiment 1 is that the cooperation between the drive component 30, the rotation component 10, and the intermediate component 40 is different.

[0084] In this embodiment, the drive output unit 31 meshes with the power receiving tooth 41, the power receiving tooth 41 meshes with the first toothed structure 12, the first toothed structure 12 meshes with the power output tooth 42, and the power output tooth 42 meshes with the second toothed structure 13. In this embodiment, the power receiving tooth 41 and the power output tooth 42 are not fixedly mounted on the transmission shaft 43, and they can rotate independently. In this way, the driving force of the drive output unit 31 is transmitted to the first toothed structure 12 through the power receiving tooth 41, thereby driving the rotating outer shell 11 to rotate and realizing the revolution of the stirring shovel assembly 20. At the same time, the first toothed structure 12 transmits the driving force to the power output tooth 42, and the power output tooth 42 transmits it to the second toothed structure 13, thereby driving the stirring shovel assembly 20 to rotate on its own axis. Thus, the revolution and rotation of the stirring shovel assembly 20 are realized.

[0085] Similarly, the meshing relationship between the power receiving tooth 41 and the power output tooth 42 and the first tooth structure 12 and the second tooth structure 13 can be interchanged, which will not be elaborated here.

[0086] It should also be noted that the configurations in the aforementioned embodiments, such as the power receiving tooth 41 and the power output tooth 42 being located on both sides of the extended axis of the power output shaft 32, the power receiving tooth 41 and the power output tooth 42 being located on one side of the extended axis of the power output shaft 32, and the axis of the transmission shaft 43 coinciding with the axis of the power output shaft 32, are all applicable to this embodiment.

[0087] It should be noted that the specific arrangement of the drive component 30, the rotation component 10, and the intermediate component 40 in this application is not limited to the arrangement methods listed in the above embodiments, and can be adjusted accordingly as needed. Furthermore, "multiple" in the above embodiments of this application refers to at least two.

[0091] 3. The relationship between the revolution direction and the rotation direction of the mixing shovel assembly can be adjusted to achieve rotation in the same direction and opposite directions.
