Specifically, the mixing cup 20 comprises a cup body 21 and a cup cover 22, the cup body 21 is a hollow cavity structure with an open top, the cup cover 22 covers the open top of the cup body 21, and the cup body 21 and the cup cover 22 enclose to form a containing cavity for containing food. The bottom of the cup body 21 of the mixing cup 20 is provided with a cup shaft 23 extending upwards, wherein the cup shaft 23 can be integrally formed with the cup body 21 or the cup shaft 23 is mounted on the bottom of the cup body 21 through a fastener. For example, in the present embodiment, the bottom of the cup shaft 23 is provided with a fixing hole 234, the bottom center of the cup body 21 is provided with a mounting hole, the fixing hole 234 of the cup shaft 23 is aligned with the mounting hole of the cup body 21, and then a fastener (e.g., a screw) sequentially passes through the mounting hole and the fixing hole 234 to lock and fix the cup body 21 and the cup shaft 23. The cutter 30 comprises a cutter shaft 31 and a blade 33 connected with the cutter shaft 31, a cutter shaft plug block 32 is arranged at the bottom of the cutter shaft 31, a cutter shaft inner hole 301 is arranged on the cutter shaft plug block 32, and the cutter shaft inner hole 301 can be a cylindrical hole with a smooth hole wall and a downward opening. And because the diameter of the cutter shaft inner hole 301 is greater than the maximum diameter of the cup shaft 23, a certain gap is formed between the outer circumferential surface of the cup shaft 23 and the inner circumferential surface of the cutter shaft inner hole 301, so that the contact area between the cutter shaft inner hole 301 and the cup shaft 23 is as small as possible, and the cutter shaft 31 is easy to incline when the cutter is stopped.

Specifically, the hole wall of the arbor inner hole 301 opposite to the top end surface of the cup shaft 23 (i.e. the top wall of the arbor inner hole 301) is provided with a protrusion 321, and the protrusion 321 may be set to be hemispherical, conical or other shapes. After the cup shaft 23 is inserted into the cutter shaft inner hole 301, the protrusion 321 forms a point contact with the top end surface of the cup shaft 23, so that the supporting area of the cup shaft 23 on the cutter shaft 31 is further reduced, and the cutter shaft 31 is more easily inclined.

Referring to fig. 3 to 5, further, the cutter 30 further includes a cutter shaft plug 32 embedded in the bottom of the cutter shaft 31, the cutter shaft plug 32 is in a cylindrical shape with a downward opening, and an inner cavity of the cutter shaft plug 32 forms a cutter shaft inner hole 301.

When the cutter shaft 31 rotates, the groove wall of the limiting groove exerts an acting force on the limiting rib, and the cutter shaft stopper 32 can be driven to rotate together. And the limiting groove is in limiting fit with the limiting rib, so that the cutter shaft plug block 32 and the cutter shaft 31 can be limited to rotate relatively, and the slipping phenomenon is prevented. Optionally, the limiting rib is arranged in a long strip shape, for example, the limiting rib can extend to the other end along one end of the cutter shaft plug block 32, and the limiting groove is matched with the limiting rib in shape, so as to improve the reliability of limiting matching. In order to further ensure the limiting reliability, optionally, at least two limiting grooves are formed in the inner circumferential surface of the jack at intervals along the circumferential direction, and the number of the limiting ribs is matched with that of the limiting grooves.

During assembly, the cutter shaft plug block 32 is inserted into the insertion hole of the cutter shaft 31, and when the cutter shaft plug block 32 is assembled in place, the limiting flange 323 on the cutter shaft plug block 32 abuts against the step surface to prevent the cutter shaft plug block 32 from being inserted too deeply, and meanwhile, the fit clearance between the cutter shaft plug block 32 and the cutter shaft 31 can be smaller, and the fit is tighter.

In one embodiment, the top of the cup shaft 23 is cylindrical or hemispherical. For example, the top of the cup shaft 23 may be formed in a cylindrical shape, and the top surface of the cup shaft 23 may be formed in a flat surface. For another example, the top of the cup shaft 23 may be formed in a hemispherical shape, and in this case, the top surface of the cup shaft 23 is formed in an arc shape that is arched upward, so that the point contact area between the protrusion 321 at the top of the cutter shaft inner hole 301 and the top surface of the cup shaft 23 is smaller, and the cutter shaft 31 is more easily inclined when the main body 10 is separated from the cutter shaft 31.

In one embodiment, the difference between the diameter of the inner hole 301 of the cutter shaft and the maximum diameter of the cutter shaft 31 is 0.2 mm-1 mm. Therefore, when the good support of the cup shaft 23 on the cutter shaft 31 is ensured, and the main machine 10 is separated from the cutter shaft 31, the cutter shaft 31 can be smoothly inclined, and the guarantee is provided for quick cutter stop.

Therefore, when the cup cover 22 is opened after the food processor is stopped, the cutter shaft 31 is inclined, if the cutter shaft 31 moves upwards relative to the cup shaft 23, the limiting step 233 on the cup shaft 23 can limit the cutter shaft 31 to a certain extent, the cutter shaft 31 is prevented from being directly separated from the cup shaft 23, and the use safety is further improved. And the peripheral surface of the main shaft body 231 is provided with a boss 232, the distance between the boss 232 and the hole wall of the cutter shaft inner hole 301 is small, and when the cutter shaft 31 inclines, the boss 232 can collide with the hole wall of the cutter shaft inner hole 301 quickly, so that the cutter stopping is further accelerated.

In one embodiment, the dimension L of the retention step 233 in the radial direction of the cup axis 23 is greater than 0.2mm. Therefore, the limiting step 233 has a larger size in the radial direction of the cup shaft 23, the effective blocking effect of the limiting step 233 on the inner hole 301 of the cutter shaft can be increased, and the safety is further improved.

In one embodiment, the boss 232 is disposed annularly around the spindle body 231. Through setting up boss 232 to the annular, when arbor 31 axle center changed to equidirectional not, annular boss 232 homoenergetic collided with arbor hole 301's pore wall to increased rotational inertia's loss speed, made arbor 31 can be in the very short time quick stall, improved safety in utilization.

Alternatively, in other embodiments, the boss 232 is provided in plurality, and the plurality of bosses 232 are arranged at intervals along the circumferential direction of the main shaft body 231. Due to the arrangement, when the main machine 10 is separated from the cutter shaft 31, when the axis of the cutter shaft 31 is changed to different directions, collision and friction between the hole wall of the cutter shaft inner hole 301 and the boss 232 of the cup shaft 23 are ensured to a greater extent, so that the cutter shaft 31 can stop rotating more quickly.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the inventive concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
