The driving gear ring 281 includes an inner gear ring 285. The driven gear 282 meshes with the inner gear ring 285 inside the inner gear ring 285. The driving gear ring 281 is fixed on the main driving shaft 21, and the driven gear 282 is fixed on the driven shaft 22. The motor 29 drives the main driving shaft 21 to rotate. When the main driving shaft 21 drives the driving gear ring 281 to rotate, the driven gear 282 rotates together with the driving gear ring 281, and the rotation directions of the driven gear 282 and the driving gear ring 281 are the same.

[0023] The mixing cup assembly 10 includes a mixing cup 11 and a chassis 12 disposed at the bottom of the mixing cup 11. The main driving shaft 21 and the driven shaft 22 respectively penetrate through the chassis 12.

Through the meshing between the driving gear ring 281 and the driven gear 282, the driven shaft 22 rotates together with the main drive shaft 21 in the same direction. The main drive shaft 21 drives the active knife 211 to rotate together, and the driven shaft 22 drives the driven knife 221 to rotate together, so as to efficiently beat and crush food ingredients. Since the driven shaft 22 and the main drive shaft 21 rotate in the same direction, that is to say, the active knife 211 and the driven knife 221 rotate in the same direction. In this way, the active knife 211 and the driven knife 221 rotate more smoothly and generate less noise.

[0025] In the illustrated embodiment, the active knife 211 is detachably provided at the top of the main drive shaft 21, and the driven knife 221 is detachably provided at the top of the driven shaft 22.

The active knife 211 is provided with a main drive hole 2111 matching the main drive section 212. The main drive hole 2111 includes a convex angle extending vertically in the vertical direction. In this way, the main drive edge 2121 has a downward limiting effect on the active knife 211, so that the active knife 211 cannot axially disengage from the main drive shaft 21 upward during high-speed rotation.

[0027] The driven shaft 22 includes a slave drive section 222. The slave drive section 222 includes a plurality of slave drive edges 2221 extending in the vertical direction. The plurality of slave drive edges 2221 are gradually deflected along the circumferential direction of the slave drive section 222. The deflection direction of the plurality of slave drive edges 2221 from bottom to top is opposite to the rotation direction of the driven knife 221. The driven knife 221 is provided with a slave drive hole 2211 matching the slave drive section 222. The slave drive hole 2211 includes a convex angle extending vertically in the vertical direction. In this way, the slave drive edge 2221 has a downward limiting effect on the driven knife 221, so that the driven knife 221 cannot axially disengage from the driven shaft 22 upward during high-speed rotation.

The driven cutter 221 includes a driven cutter holder 2219 and a driven cutter blade 2218 disposed on the driven cutter holder 2219. The distance between the main cutter blade 2118 and the driven cutter blade 2218 in the vertical direction is between 2 mm and 50 mm. Thus, the main cutter blade 2118 and the driven cutter blade 2218 can crush food materials at different heights in the mixing cup 11, which can further improve the crushing efficiency. In some embodiments, the distance between the main cutter blade 2118 and the driven cutter 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.

[0029] The ratio of the center distance between the main drive shaft 21 and the driven shaft 22 to the inner diameter of the mixing cup 11 is between 0.25 and 0.75. Thus, the active cutter 211 and the driven cutter 221 can beat and crush the food materials in the mixing cup 11 within a relatively large radial range, and the crushing effect is better.

[0030] In some embodiments, the ratio of the center distance between the main drive shaft 21 and the driven shaft 22 to the inner diameter of the mixing cup 11 can be 0.25, 0.5, 0.75 or a value between any two adjacent ones of the above.

[0033] The chassis 12 is provided with a perforation 126 for the main drive shaft 21 and the driven shaft 22 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 main drive shaft 21 and the driven shaft 22, and on the other hand, it increases the heat dissipation area and improves the phenomenon of bottom sticking.

[0034] In the illustrated embodiment, elastic sealing rings 2884 are respectively provided on the chassis 12, the main drive shaft 21 and the driven shaft 22, which can effectively improve the assembly process tolerance, play a better sealing role, and at the same time reduce the noise.
