[0034] See also Figure 1-7 As shown, this embodiment discloses a food processor that can realize high-speed functions such as mixing, crushing, and breaking food; as well as low-speed functions such as mincing, shredding, slicing, and kneading noodles.

[0035] The food processor includes a main machine, a blending cup assembly 60 and a cup cover assembly; the blending cup assembly 60 is installed on the main machine, and the blending cup assembly 60 includes a blending cup and a knife assembly arranged at the bottom of the blending cup, and the knife assembly is connected to the transmission shaft 41; the cup cover assembly is arranged on the blending cup assembly 60. In this way, there is no need to replace the blending cup assembly 60, and the cooking requirements of different speeds can be achieved by switching the working mode of the main machine, which is simple to use and low in cost.

[0036] In the illustrated embodiment, the main machine includes a housing 10, a driving device 20, a speed change device 30 and a shift mechanism 50. The driven clutch 42 in the transmission assembly 40 moves up and down through the shift mechanism 50, and respectively engages with the second clutch 31 in the speed change device 30 and the first clutch 23 in the driving device 20 to achieve different speed outputs to meet various cooking needs.

[0037] Specifically:

[0038] The driving device 20 is installed in the housing 10, and includes a driving shaft 21, and the driving shaft 21 is provided with a driving gear 22 and a first clutch 23. The driving gear 22 is fixed on the driving shaft 21, and the first clutch 23 is detachably mounted on the top of the driving shaft 21 by screws, so that the first clutch 23 with a suitable number of teeth can be easily replaced to meet the requirements of different speed ratios.

[0039] The speed change device 30 is mounted on the drive shaft 21 and meshes with the drive gear 22. A second clutch 31 is provided at the output end of the speed change device 30. The speed of the second clutch 31 is different from that of the first clutch 23. In this embodiment, the second clutch 31 is detachably mounted at the output end of the speed change device 30. In this way, when the drive gear 22 drives the speed change device 30 to rotate, the speed change device 30 drives the second clutch 31 to rotate synchronously.

[0040] The transmission assembly 40 includes a transmission shaft 41, a driven clutch 42 and an output clutch 43. The output clutch 43 is arranged at the top of the transmission shaft 41. The driven clutch 42 is arranged on the transmission shaft 41 so as to be movable up and down. The driven clutch 42 includes a base 421, upper teeth 422 extending upward from the base 421, and lower teeth 423 extending downward from the base 421. The output clutch 43 includes an output bearing 431 and an output clutch head 432. The knife assembly is meshed with the output clutch head 432. When the transmission shaft 41 rotates, the output clutch 43 at the top of the transmission shaft 41 is driven to rotate synchronously, and then the knife assembly rotates to work.

[0041] The shift mechanism 50 is installed in the housing 10. The shift mechanism 50 is used to cause the driven clutch 42 to switch between the first position and the second position. The driven clutch 42 is matched with the first clutch 23 through the lower teeth 423 in the first position, and is matched with the second clutch 31 through the upper teeth 422 in the second position. In this way, the driven clutch 42 can move up and down through the shift mechanism 50, and respectively mesh with the second clutch 31 and the first clutch 23 to achieve different speed outputs to meet various cooking needs.

[0042] Furthermore, the width of the upper teeth 422 gradually decreases from bottom to top, and the width of the lower teeth 423 gradually decreases from top to bottom. In this way, the root width of the upper teeth 422 and the lower teeth 423 is large, the strength is good, and the tooth tip jamming can be effectively avoided during the meshing process.

[0043] In the illustrated embodiment, the upper teeth 422, the lower teeth 423, the first teeth 311 and the second teeth 231 are in a triangular ratchet shape. In this way, the root strength of the upper teeth 422 and the lower teeth 423 is better, the triangular shape is more stable, and the bevel travel guide bevel on the triangular shape ensures the reliability of the meshing process, and effectively avoids the situation of tooth tip jamming during the meshing process. Of course, the upper teeth 422 and the lower teeth 423 can also be any other suitable shape, which is not limited here.

[0044] Correspondingly, the second clutch 31 is provided with a first tooth 311 meshing with the upper tooth 422 of the driven clutch 42, and the first clutch 23 is provided with a second tooth 231 meshing with the lower tooth 423 of the driven clutch 42. In this way, the second clutch 31 achieves different speed outputs by meshing with the second clutch 31 and the first clutch 23 respectively.

[0045] In the illustrated embodiment, the driving device 20 uses a motor 24, and the driving shaft 21 is the output shaft of the motor 24. In this way, power can be output to the driven clutch 42 through the output shaft.

[0046] The speed change device 30 includes a ring gear 32 and a first planetary gear assembly 33. The first planetary gear assembly 33 includes a first gear frame 331 and a first planetary gear 332 disposed on the first gear frame 331. The first planetary gear 332 is meshed with the driving gear 22 and the ring gear 32. The second clutch 31 is fixed to the first gear frame 331. In this way, a reduction ratio of several times to dozens or even hundreds of times can be achieved, and a low speed and high torque output can be achieved.

[0047] In addition to the above-mentioned embodiment, the figure also provides another embodiment. The speed change device 30 includes a ring gear 32, a first planetary gear assembly 33 and a second planetary gear assembly 34. The first planetary gear assembly 33 includes a first gear frame 331 and a first planetary gear 332 disposed on the first gear frame 331. The first planetary gear 332 is meshed with the driving gear 22 and the ring gear 32. The second planetary gear assembly 34 includes a second gear frame 341 and a second planetary gear 342 disposed on the second gear frame 341. The first gear frame 331 is provided with a central gear 333 protruding upward. The second planetary gear 342 is meshed with the central gear 333 and the ring gear 32. The second clutch 31 is fixed to the second gear frame 341. In this way, a reduction ratio of several times to dozens or even hundreds of times can be achieved, and a low speed and high torque output can be achieved.

[0048] Furthermore, the transmission device 30 further includes a ring gear housing 35, which is connected to the ring gear 32 to form a space for accommodating the planetary gear assembly. The ring gear housing 35 and the ring gear 32 are screwed to facilitate installation and removal; specifically, in this embodiment, mounting blocks are provided on the side walls of the ring gear housing 35 and the ring gear 32, and the mounting blocks are connected by screws. In addition, the second planetary gear assembly 34 is provided with a positioning ring 343 protruding upward to locate the installation position of the second clutch 31.

[0049] It should be pointed out that one set of the first planetary gear assembly 33 or two sets, namely the first planetary gear assembly 33 and the second planetary gear assembly 34, are provided to achieve deceleration. Of course, three, four or other sets of planetary gear assemblies can also be provided in combination with factors such as the output speed, the actual required speed, the main engine structure size, etc., and there is no specific limitation here.

[0050] In the illustrated embodiment, the transmission assembly 40 further includes a gantry 44 and a bearing disposed between the driven clutch 42 and the gantry 44, and the gantry 44 is provided with a convex portion 441. Specifically, the shift mechanism 50 includes a shift motor 51, a shift arm 52 and a housing 53, the shift motor 51 is used to drive the shift arm 52 to move horizontally, the shift arm 52 is used to drive the gantry 44 to move vertically, and the convex portion 441 is movably disposed on the housing 53. In this way, the driven clutch 42 moves up and down through the shift mechanism 50, and engages with the second clutch 31 and the first clutch 23 respectively to achieve different speed outputs. Of course, the shift mechanism 50 mentioned here is only a mechanism for driving the gantry 44 and the driven clutch 42 to slide up and down, and the specific structure and form of the shift mechanism 50 are not limited here.

[0051] In addition, a third limiting member is provided between the driven clutch 42 and the gantry 44, and the third limiting member 47 is provided on the top of the bearing to further ensure the stability of the bearing position. In addition, by providing a bearing between the driven clutch 42 and the gantry 44, the driven clutch 42 can have the advantages of smooth rotation, stable operation and low noise during operation.

[0052] Furthermore, the transmission shaft 41 is provided with a driving section 411, a first stopper 45 provided at the upper end of the driving section 411, and a second stopper 46 provided at the lower end of the driving section 411, and the driven clutch 42 is provided with a driving hole 424 matched with the driving section 411. In this way, the sliding range of the driven clutch 42 is limited, which is safe and stable.

[0053] The driving hole 424 is in a flat shape to ensure clearance fit with the driving section 411. The flat shape mentioned here means that one set of opposite sides is a straight line and the other set of opposite sides is an arc convex outward.

[0054] In addition, in the illustrated embodiment, the transmission shaft 41 and the drive shaft 21 are coaxially arranged, which facilitates the engagement of the driven clutch 42 with the second clutch 31 and the first clutch 23; it also makes the internal structure of the main engine more compact and the space utilization rate higher.

[0055] The first limiter 45 and the second limiter mentioned here refer to limiter clips, which extend outwardly away from the driving end, thereby limiting the movement of the driven clutch 42 slidably arranged on the driving end. Of course, a step portion and a limiter block can also be provided to limit the movement of the driven clutch 42.
