In the present embodiment, the first shifting group 2120 and the second shifting group 2130 are stacked, and there is a certain gap between them to avoid interference with each other, and the shifting transmission can be reliably realized. In addition, a sleeve 2300 is disposed between the power output shaft 2200 and the cover plate 2300, so that the rotation of the power output shaft 2200 is ensured by the positioning of the sleeve 2300.

The driving gear 1300 meshes with the first gear set 2121, and the center position of the first planet carrier 2122 A first ring gear 21223 is disposed, the transmission gear 2140 is engaged with the first carrier 2122, the other end is meshed with the second gear set 2131, and the second carrier 2132 is provided with a second ring gear 21323 at the center of the second carrier 2132. The first outer ring gear 2150 on the power output shaft 2200 is meshed with the second ring gear 21323. Further, the driving gear 1300 is located at a center position of the first gear set 2121, and the transmission gear 2140 is located at a center position of the second gear set 2131 to ensure the balance of the force. The actual transmission mode is as follows: the driving gear 1300 transmits power to the first gear set 2 121 to drive the first gear set 2121 to rotate, and since the first carrier 2122 is disposed on the first gear set 21 21 , The first planet carrier 2122 can be driven to rotate. The one end of the transmission gear 2140 is meshed with the first carrier 2122, and the other end is meshed with the second gear set 2131, so that the power of the first carrier 2122 is transmitted through the transmission gear 2140, and the power can be transmitted to the second gear set. 2131. Similarly, since the second planet carrier 2132 is disposed on the second gear set 2131, the second planet carrier 2132 follows the first The two gear sets 2131 rotate together, and since the power output shaft 2200 and the second carrier 2132 are meshed and driven by the first outer ring gear 2150 and the second inner ring gear 21323, the power is finally transmitted to the power output shaft. On the 2200, the processing tool 7000 that drives the connection on the power output shaft 2200 is rotated to realize the function of processing the processed food. With such a setting method, the gear ratio can be changed by changing the number of teeth of the corresponding gear, so that different magnitudes of torque can be output, and the setting method is flexible and variable, which can meet the different use requirements of the processing 吋 for the rotation speed requirement, and the improvement is improved.

[0033] Preferably, as shown in FIG. 1 to FIG. 3, in order to reliably perform shifting and transmitting power, and simplify the structure, the difficulty and cost of manufacturing are reduced. In the present embodiment, the first gear set 2121 includes three. The first rotating gear 21211 is evenly arranged, and the driving gear 1300 is disposed at the center positions of the three first rotating gears 21211, and both mesh with the three first rotating gears 21211. Therefore, when the driving gear 1300 is rotated, the three first rotating gears 21211 can be driven to rotate at the same time, and the rotation is stable and reliable. This arrangement not only satisfies the use requirements, but also saves manufacturing costs. Of course, it is understood that the number of gears in the first gear set 2121 can also be set to four, five or more depending on the usage requirements.

Specifically, as shown in FIG. 1 to FIG. 3, the first planet carrier 2122 includes a first bottom plate 21221 and three first fixing posts 21222 evenly distributed on the first bottom plate 21221, and three first rotating gears 21211. The corresponding internal activities are disposed on the first fixing post 21222, and the first internal spurs 21223 are disposed at a central position of the first bottom plate 21221. Thus, after the first rotating gear 21211 is rotated, under the transmission of the first fixed post 21222, the entire first carrier 2122 can be pulled to realize the function of transmitting power. The first ring gear 21223 is disposed at a center position of the first bottom plate 21221, so that when the transmission gear 2140 is engaged with the first ring gear 21223 thereon, the smoothness of the rotational force can be maintained.

At the center positions of the three second rotating gears 21311, both of them mesh with the three second rotating gears 21311. Therefore, after the transmission gear 2140 is rotated, the three second rotating gears 21311 can be driven to rotate at the same time, and the rotation is smooth and reliable. This arrangement not only satisfies the use requirements, but also saves manufacturing costs. Of course, it can be understood that the number of gears in the second gear set 2131 can be set to four, five or more according to the use requirements.

[0036] Specifically, as shown in FIGS. 1 to 3, the second planet carrier 2132 includes a second bottom plate 21321 and is evenly distributed in the second Three second fixing posts 21322 and three second rotating gears 21311 are respectively disposed on the second fixing post 21322, and the second internal latch 21323 is disposed at a central position of the second bottom plate 21321. Thus, after the second rotating gear 21311 is rotated, under the second fixed column 21322, the entire second carrier 2132 can be pulled to rotate, thereby rotating the power output shaft 2200. Similarly, the second ring gear 2 1323 is disposed at a central position of the second bottom plate 21321, so that when the first outer ring gear 2150 on the power output shaft 2200 is engaged with the second inner ring gear 21323 thereon, the rotation can be maintained. The stability of power.

Specifically, as shown in FIG. 1 to FIG. 3, the power output shaft 2200 is a hollow shaft, and the transmission gear 2140 is provided with a concentric shaft 3000 coaxial with the power output shaft 2200, and the concentric shaft 3000 is movably inserted in the power. The output shaft 220 0 is further included, and the processing tool 7000 is also detachably coupled to the concentric shaft 3000. In this way, the shifting of the internal shifting mechanism enables the PTO shaft 2200 and the concentric shaft 3000 to have different rotational speeds and thus different torques to meet different usage requirements. The specific speed setting of the power output shaft 2200 and the concentric shaft 300 0 can be set according to actual design requirements. In the present embodiment, the power output shaft 2200 is set to output a large torque, and the concentric shaft 3000 is set to have a higher rotation speed, and the processing tool 7000 can be detachably connected to the concentric shaft 3000 or The processing of food is performed on the power output shaft 2200. With such an arrangement, the power output shaft 2200 and the concentric shaft 3000 can both rotate at the same time and have different rotational speeds, so that the machining tool 7 000 can be connected to the power output shaft 2200 according to actual use requirements. Connected to the concentric shaft 3000, the selection is varied and the functions are comprehensive, which improves the practicality of the food mixer.

Specifically, as shown in FIGS. 1 to 4, in the present embodiment, the planetary gearbox 2000 is coupled to the first rotating shaft 1100, so that the second rotating shaft 1200 can be directly coupled to the processing tool 7000. To ensure the reliability of the driving force transmission, at least one of the power output shaft 2200 and the second rotating shaft 1200 is further connected with a transmission structure 4000, and the machining tool 7000 is detachably coupled to the transmission structure 4000. The transmission structure 4000 has a stable transmission and rotation function, which can prevent the slippage and affect the power transmission efficiency after the connection. In this way, the transmission structure 4000 can be simultaneously disposed on the power output shaft 2200 or the second rotating shaft 1200 or on the power output shaft 2200 and the second rotating shaft 1200 according to specific design requirements, thereby ensuring the transmission. Reliability and meet different design requirements.

Specifically, as shown in FIG. 2 to FIG. 4, in the embodiment, the transmission structure 4000 is coupled to the power output shaft 2200, including the transmission frame 4100, the planetary gear 4200, and the second planetary ring gear 4300 having internal teeth. Planet tooth The wheel 4200 is movably disposed on the transmission frame 4100 through the transmission shaft 4400, and is engaged with the second planetary ring gear 4300. The transmission frame 4100 is provided with a connecting hole 4500 for connecting with the power output shaft 2200, and the power output shaft 2200 is inserted in the The connecting tool 7000 is detachably coupled to the drive shaft 4400 by being fastened by fasteners. With such an arrangement, the entire transmission frame 4100 and the planetary gears 4200 are disposed in the second planetary ring gear 4300. Under the driving of the power output shaft 2200, the transmission frame 4100 can be rotated, thereby driving the planetary gear 4200 to rotate, and the transmission The shaft 4400 is coupled to the planetary gear 4200. When the planetary gear 4200 is rotated, the transmission shaft 4400 can be rotated to drive the processing tool 7 000 to rotate with the transmission shaft 4400 to perform food processing. The rotation of the processing tool 7000 is centered on the connection point of the transmission frame 4100 and the power output shaft 2200, and is rotated by the vertical distance between the transmission shaft 4400 and the power output shaft 2200. Therefore, the rotation mode can be expanded. The area that can be processed by the tool 7000 (such as the mixing area that can be stirred by the flour to ensure the uniformity of food agitation). Since the second planetary ring gear 4300 is disposed and meshed with the planetary gears 4200 by the rotation of the processed food, the planetary gears 4200 can be supported to avoid the planetary gears due to the imbalance of the force. 4200 suffocation occurred. Moreover, the second planetary ring gear 4300 can also provide a guiding function for the rotation of the planetary gear 4200, ensuring the reliability of the rotational agitation.

Rotatingly coupled to the carriage 4100, the machining tool 7000 can be coupled to either of the two transmission shafts 4400. Of course, if the structure of the two transmission shafts 4400 connected to the processing tool 7000 is different, the matching tool 7000 can be selectively connected to the corresponding transmission shaft 4400. By using such a setting method, the convenience of the installation and connection of the processing tool 7000 is improved. To ensure the smoothness of the rotation, the connection hole 4500 is opened at the center of the transmission frame 4100, ensuring that the planetary gears 4200 at both ends of the transmission frame 4100 can receive a balanced rotational force.

[0041] Specifically, as shown in FIG. 1, in order to improve the convenience of use, a handle 5000 is further provided on the casing of the drive motor 1000. In this way, in actual use, by holding the handle 5000, the whole motor can be manually held for food processing, so that the motor can be used not only for processing the food in the container, but also by artificial hand support. It is used to process food in other containers, so that the range of use of the motor is not limited to only the food in the fixed matching container, but also can be artificial according to the specific situation. The hand-held processing for food in other containers further increases the range of application, the utility is greatly improved, and the usability is good.

[0042] As shown in FIG. 5, an embodiment of the present invention further provides a food processor including a container 6000 for holding food and a processing tool 7000 for processing food, and the above-mentioned motor having a planetary gearbox. The motor having the planetary gearbox is disposed on the vessel 6000 and is coupled to the processing tool 7000 and extends the processing tool 7000 into the vessel 6000. Thus, in use, the processed food will need to be placed in the container 6000, and then the processing tool 7000 can perform the function of processing the food in the container 6000 under the driving of the motor. In this embodiment, the food processor is a blender for stirring food. To improve the use function, the processing tool 7000 is a juice knife for preparing juice or a stirring hook for stirring flour or used for breaking up. Egg egg baskets or meat cleavers for minced meat can be used to complete different food processing components, and will not be explained here. The motor can not only output different speeds stably, but also can be used to connect the processing tool 7000 for processing food at both ends, thereby improving the function of the food processor, and the functions are comprehensive and diverse, and can meet different needs, and is convenient and practical.

[0043] Specifically, the processing tool 7000 may be a juicer or dough agitating hook, a paste agitator, an egg cage, a meat cleaver, a slicing disc. These processing tools 7000 are the same as those commonly found on the market. For example, the juicer has a broken knife set, the dough stirrer has a spiral stirring hook, and the meat cleaver has a blade for the ground meat. Moreover, these processing tools 7000 each have a connection portion through which the detachable connection can be made with the drive shaft 4400 or with the second rotary shaft 1200 or the concentric shaft 3000. The specific structure of the connecting portion is set in accordance with the structure of the transmission shaft 4400 or the second rotating shaft 1200 or the concentric shaft 3000 to be connected, so that the corresponding connection can be realized.
