The embodiment of the application provides a food material crusher, which can be a juicer or a wall breaking machine and the like which need to crush food materials. As shown in fig. 1 and 5, the food material crusher comprises: the food cutting machine comprises a machine body assembly 1, a cutting assembly 4 and a driving assembly 5, wherein the machine body assembly 1 is provided with a first inner cavity 121, the first inner cavity 121 is used for containing food materials and water, and liquid obtained after cutting the food materials is also placed in the first inner cavity 121; the cutting assembly 4 comprises a cutting knife 41, the cutting knife 41 is located in the first inner cavity 121 and is used for cutting the food material under the driving of the driving assembly 5, so as to realize the crushing of the food material.

The driving assembly 5 includes a first magnet 52, a second magnet 53 and a driving member, a magnetic attraction force exists between the first magnet 52 and the second magnet 53, the second magnet 53 is connected with the cutting knife 41, the first magnet 52 rotates under the driving of the driving member, and under the action of the magnetic attraction force between the first magnet 52 and the second magnet 53, the second magnet 53 can rotate along with the first magnet 52, so as to drive the cutting knife 41 to rotate, thereby realizing the cutting of the food material.

Specifically, as shown in fig. 8, the first magnet 52 includes a plurality of first magnetic poles, and the magnetic polarities of the adjacent first magnetic poles are opposite, and similarly, the second magnet 53 includes a plurality of second magnetic poles, and the magnetic polarities of the adjacent second magnetic poles are opposite.

In the embodiment shown in fig. 8, the first magnetic pole of the first magnet 52 includes a first N pole 523 and a first S pole 524 that are opposite in magnetism, and the first N pole 523 and the first S pole 524 are spaced apart from each other, and in the embodiment shown in fig. 9, the second magnetic pole of the second magnet 53 includes a second N pole 533 and a second S pole 534 that are opposite in magnetism. In the food material crusher, the first magnet 52 and the second magnet 53 are oppositely arranged, the first N pole 523 of the first magnet 52 and the second S pole 534 of the second magnet 53 are oppositely arranged, and have a magnetic attraction therebetween, and the first S pole 524 of the first magnet 53 and the second N pole of the second magnet 53 are oppositely arranged, and have a magnetic attraction therebetween.

It is understood that, in the first and

second magnets

52 and 53, when the first N pole 523 and the second S pole 534 are opposite to each other and the first S pole 524 and the second N pole 533 are opposite to each other, there is a magnetic attraction between the poles, and the attraction is greater at this time, so that the attraction between the first magnet 52 and the second magnet 53 is greater; when the first N pole 523 and the second S pole 534 of the first magnet 52 are offset (i.e. they are no longer directly opposite), the area where they are directly opposite decreases, and the attractive force between the magnetic poles decreases, so that the attractive force between the first magnet 52 and the second magnet 53 decreases; when there is no mutually opposite region between the first N pole 523 and the second S pole 534, the first N pole 523 and the second N pole 533 are opposite, and the first S pole 524 and the second S pole 534 are opposite, and at this time, a repulsive force is generated between the first magnet 52 and the second magnet 53.

Therefore, in the present application, when the food material crusher normally works, the N pole of the first magnet 52 is opposite to the S pole of the second magnet 53, the attractive force between the first magnet 52 and the second magnet 53 is large, and the driving member drives the cutting knife 41 to rotate through the magnetic force between the first magnet 52 and the second magnet 53, which has the advantages of high driving precision and stability.

When the food material crusher exceeds the rated load or the cutting knife 41 is stuck, the rotation resistance of the cutting knife 41 is increased, so that the rotation resistance of the second magnet 53 is increased, the rotation speed of the second magnet is reduced, and the rotation of the first magnet 52 is driven by the driving piece, therefore, the rotation speed between the first magnet 52 and the second magnet 53 is different, the first magnet 52 and the second magnet 53 rotate relatively, so that the N pole of the first magnet 52 is not directly opposite to the S pole of the second magnet 53, the attraction force between the first magnet 52 and the second magnet is reduced or disappears, the second magnet 53 cannot rotate along with the first magnet 52, namely, the second magnet 53 and the cutting knife 41 stop rotating. Consequently, this drive assembly 5 makes food material breaker surpass rated load or cutting knife 41 card when dead, cutting knife 41 can automatic stop rotate to reduce the risk of damaging cutting knife 41 and drive assembly 5 under this operating mode, improve food material breaker's life.

In one possible design, as shown in fig. 8, the first magnet 52 includes an even number of first magnetic poles, and each of the first magnetic poles is symmetrical with respect to the rotation center of the first magnet 52, the first magnetic poles include a first N pole 523 and a first S pole 524, and the number of the first N pole 523 and the first S pole 524 is equal; similarly, as shown in fig. 9, the second magnet 53 includes an even number of second magnetic poles, each of which is symmetrical with respect to the rotational center of the second magnet 53, the second magnetic poles include a second N pole 533 and a second S pole 534, and the number of the second N pole 533 and the number of the second S pole 534 are equal.

In this embodiment, when the numbers of the N poles and the S poles of the first magnet 52 and the second magnet 53 are equal and symmetrical, the magnetic fields of the first magnet 52 and the second magnet 53 are stable.
