The cooking machine includes: a main body, including a motor and a gearbox, the gearbox includes a driving gear, a first driven gear and a second driven gear, the first driven gear and the second driven gear are respectively meshed with the driving gear, the driving gear is fixedly arranged on the output shaft of the motor, the first driven gear is fixedly arranged on a first driven shaft, the second driven gear is fixedly arranged on a second driven shaft, and the rotational speed of the driving gear is greater than the rotational speed of the first driven gear, the rotational speed of the driving gear is less than the rotational speed of the second driven gear; and a mixing cup assembly, assembled on the main body, the mixing cup assembly includes a mixing cup and a chassis arranged at the bottom of the mixing cup, the first driven shaft and the second driven shaft respectively penetrate the chassis, and the first driven shaft is provided with a first driven knife, the second driven shaft is provided with a second driven knife. When the main body is started, the motor drives the driving gear to rotate, the driving gear drives the first driven gear and the second driven gear to rotate. Since the first driven gear and the second driven gear are respectively meshed with the driving gear, the rotational directions of the first driven gear and the second driven gear are the same. That is to say, the first driven shaft and the second driven shaft respectively drive the first driven knife and the second driven knife to rotate in the same direction. On the one hand, it can efficiently stir and crush food materials, and on the other hand, it makes the first driven knife and the second driven knife rotate more smoothly and generate less noise; in addition, since the rotational speed of the driving gear is greater than the rotational speed of the first driven gear, the rotational speed of the driving gear is less than the rotational speed of the second driven gear, that is to say, the rotational speed of the first driven knife is less than the rotational speed of the motor, the rotational speed of the second driven knife is greater than the rotational speed of the motor, the first driven knife rotates at a low speed, and the second driven knife rotates at a high speed, which can further reduce noise.

[0005] Further, the driving gear includes a first gear portion and a second gear portion coaxially arranged with the first gear portion. The first gear portion meshes with the first driven gear, and the second gear portion meshes with the second driven gear. The radial dimension of the first gear portion is smaller than that of the first driven gear, and the radial dimension of the second gear portion is larger than that of the second driven gear. In this way, deceleration is achieved through the cooperation of the first gear portion and the first driven gear, and speed increase is achieved through the cooperation of the second gear portion and the second driven gear, and the structure is simple.

The second driven shaft includes a second driven driving section, the second driven driving section includes a plurality of second driven driving edges extending in the up-down direction, the plurality of second driven driving edges are gradually deflected along the circumferential direction of the second driven driving section, the deflection direction of the plurality of second driven driving edges from bottom to top is opposite to the rotation direction of the second driven cutter, the second driven cutter is provided with a second driven driving hole matching the second driven driving section, and the second driven driving hole includes a convex angle extending vertically in the up-down direction. Thus, the second driven driving edge has a downward limiting effect on the second driven cutter, so that the second driven cutter cannot axially disengage from the second driven shaft 23 upward during high-speed rotation.

[0010] Further, the first driven cutter includes a first driven tool holder and a first driven blade provided on the first driven tool holder, the second driven cutter includes a second driven tool holder and a second driven blade provided on the second driven tool holder, and the top end of the first driven blade is lower than the bottom end of the second driven blade. Thus, the first driven blade rotates at a low speed, which is more conducive to agitating the ingredients deposited at the bottom of the mixing cup, and the second driven blade rotates at a high speed, which is more conducive to crushing the ingredients at a corresponding height.

[0011] Further, the distance between the first driven blade and the second driven blade in the vertical direction is between 2 mm and 50 mm. Thus, the cooperation between the first driven blade and the second driven blade can further improve the crushing efficiency.

[0012] Further, the chassis is provided with a through hole for the first driven shaft and the second driven shaft to pass through and a convex platform surrounding the through hole.

[0021] Please refer to Figures 1 to 5 , the cooking machine 100 includes a mixing cup assembly 10, a main body 20, and a cup cover assembly 30. The mixing cup assembly 10 is assembled to the main body 20, and the cup cover assembly 30 is covered on the mixing cup assembly 10.

[0022] The main body 20 includes a motor 29 and a gearbox 28. The gearbox 28 includes a driving gear 281, a first driven gear 282, and a second driven gear 283. The first driven gear 282 and the second driven gear 283 are respectively meshed with the driving gear 281. The driving gear 281 is fixed on the output shaft of the motor 29. The first driven gear 282 is fixed on a first driven shaft 22, and the second driven gear 283 is fixed on a second driven shaft 23. And the rotational speed of the driving gear 281 is greater than the rotational speed of the first driven gear 282, and the rotational speed of the driving gear 281 is less than the rotational speed of the second driven gear 283. The motor 29 drives the driving gear 281 to rotate, and the driving gear 281 drives the first driven gear 282 and the second driven gear 283 to rotate. Since the first driven gear 282 and the second driven gear 283 are respectively meshed with the driving gear 281, the first driven gear 282 and the second driven gear 283 rotate in the same direction.

[0023] The stirring cup assembly 10 includes a stirring cup 11 and a chassis 12 disposed at the bottom of the stirring cup 11. The first driven shaft 22 and the second driven shaft 23 respectively penetrate through the chassis 12, and the first driven shaft 22 is provided with a first driven knife 211, and the second driven shaft 23 is provided with a second driven knife 221. The stirring cup 11 is used to hold food ingredients. In the illustrated embodiment, the chassis 12 is provided with a heating tube to heat the food ingredients in the stirring cup 11. In other embodiments, the chassis 12 is not provided with a heating tube and cannot heat the food ingredients.

[0024] When the host 20 is started, the motor 29 drives the driving gear 281 to rotate. The driving gear 281 drives the first driven gear 282 and the second driven gear 283 to rotate. Since the first driven gear 282 and the second driven gear 283 are respectively engaged with the driving gear 281, the first driven gear 282 and the second driven gear 283 rotate in the same direction. That is to say, the first driven shaft 22 and the second driven shaft 23 respectively drive the first driven knife 211 and the second driven knife 221 to rotate in the same direction. On the one hand, it can efficiently beat and crush the food ingredients, and on the other hand, it makes the first driven knife 211 and the second driven knife 221 rotate more smoothly and generate less noise. In addition, since the rotation speed of the driving gear 281 is greater than the rotation speed of the first driven gear 282, and the rotation speed of the driving gear 281 is less than the rotation speed of the second driven gear 283, that is to say, the rotation speed of the first driven knife 211 is less than the rotation speed of the motor 29, and the rotation speed of the second driven knife 221 is greater than the rotation speed of the motor 29. The first driven knife 211 rotates at a low speed, and the second driven knife 221 rotates at a high speed, which can further reduce the noise.

The first gear portion 2811 is engaged with the first driven gear 282, and the second gear portion 2812 is engaged with the second driven gear 283. The radial dimension of the first gear portion 2811 is smaller than the radial dimension of the first driven gear 282, and the radial dimension of the second gear portion 2812 is larger than the radial dimension of the second driven gear 283. Thus, deceleration is achieved by the cooperation of the first gear portion 2811 and the first driven gear 282, and speed increase is achieved by the cooperation of the second gear portion 2812 and the second driven gear 283, and the structure is simple.

[0026] The first gear portion 2811, the second gear portion 2812, the first driven gear 282, and the second driven gear 283 are all helical gears, and the normal module of the first gear portion 2811, the second gear portion 2812, the first driven gear 282, and the second driven gear 283 is between 1 and 2.5, the helix angle is between 15 degrees and 30 degrees, and the tooth thickness is between 5 mm and 30 mm. In this way, the cooperative transmission between the driving gear 281 and the first driven gear 282 and the second driven gear 283 is more stable and reliable. In the illustrated embodiment, the first gear portion 2811 is disposed above the second gear portion 2812.

In this way, the crushing effect of the first driven blade 211 and the second driven blade 221 on the food ingredients is better, and the noise can be reduced better.

[0029] In some embodiments, the ratio of the rotational speed of the first driven gear 282 to the rotational speed of the driving gear 281 can be 0.26, 0.75, 0.99, or a value between any two adjacent ones of the above. The ratio of the rotational speed of the second driven gear 283 to the rotational speed of the driving gear 281 can be 1.1, 2, 3, 3.9, or a value between any two adjacent ones of the above.

After the food processor 100 finishes working, the first driven blade 211 and the second driven blade 221 can be detached for cleaning, making it more convenient and thorough for the user to clean the food processor 100.

[0031] The first driven shaft 22 includes a first driven driving section 222. The first driven driving section 222 includes a plurality of first driven driving edges 2221 extending in the up and down direction. The plurality of first driven driving edges 2221 are gradually deflected along the circumferential direction of the first driven driving section 222. The deflection direction of the plurality of first driven driving edges 2221 from bottom to top is opposite to the rotation direction of the first driven cutter 211. The first driven cutter 211 is provided with a first driven driving hole 2111 matching the first driven driving section 222. The first driven driving hole 2111 includes a convex angle extending vertically in the up and down direction. In this way, the first driven driving edge 2221 has a downward limiting effect on the first driven cutter 211, so that the first driven cutter 211 cannot axially disengage from the first driven shaft 22 upward during high-speed rotation.

[0032] The second driven shaft 23 includes a second driven driving section 232. The second driven driving section 232 includes a plurality of second driven driving edges 2321 extending in the up and down direction. The plurality of second driven driving edges 2321 are gradually deflected along the circumferential direction of the second driven driving section 232. The deflection direction of the plurality of second driven driving edges 2321 from bottom to top is opposite to the rotation direction of the second driven cutter 221. The second driven cutter 221 is provided with a second driven driving hole 2211 matching the second driven driving section 232. The second driven driving hole 2211 includes a convex angle extending vertically in the up and down direction. In this way, the second driven driving edge 2321 has a downward limiting effect on the second driven cutter 221, so that the second driven cutter 221 cannot axially disengage from the second driven shaft 23 upward during high-speed rotation.

[0033] The first driven cutter 211 includes a first driven tool holder 2119 and a first driven blade 2118 arranged on the first driven tool holder 2119. The second driven cutter 221 includes a second driven tool holder 2219 and a second driven blade 2218 arranged on the second driven tool holder 2219. The top end of the first driven blade 2118 is lower than the bottom end of the second driven blade 2218. In this way, the first driven blade 2118 rotates at a low speed, which is more conducive to stirring the food materials deposited at the bottom of the mixing cup 11. The second driven blade 2218 rotates at a high speed, which is more conducive to crushing the food materials at a corresponding height.

[0034] The distance between the first driven blade 2118 and the second driven blade 2218 in the vertical direction is between 2 mm and 50 mm. In this way, the cooperation between the first driven blade 2118 and the second driven blade 2218 can further improve the crushing efficiency. In some embodiments, the distance between the first driven blade 2118 and the second driven blade 2218 in the vertical direction can be 2 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm or a value between any two adjacent ones of the above.

[0035] The chassis 12 is provided with a perforation 126 for the first driven shaft 22 and the second driven shaft 23 to pass through, and a boss 125 surrounding the perforation 126. By providing the boss 125, on the one hand, it is convenient to limit the first driven shaft 22 and the second driven shaft 23, and on the other hand, it increases the heat dissipation area and improves the phenomenon of bottom sticking.
