As shown in connection with fig. 1-5. The utility model discloses a food chopper includes at least: a cup body 1 for providing a chopping processing space for food; a cutter assembly 2 detachably mounted on the magnetic cup shaft 11, the cutter assembly 2 including a cutter shaft 21 having a cutter shaft fixing hole 211 at a lower end thereof, a plurality of chopping cutters 22 fixed to the cutter shaft 21, and a lower connector 23 provided at an upper end of the cutter shaft 21; the cup cover 3 can be covered on the cup body 1, and the machine head component 4 is fixed on the cup cover 3 and used for driving the cutter component 2 to rotate, a motor 41 electrically connected with an external power supply and an upper connector 42 connected with a transmission shaft of the motor 41 are arranged in the machine head component 4, and the upper connector 42 can be coupled and connected with the lower connector 23; the cutter assembly 2 further comprises a magnetic conduction piece made of magnetic conduction materials such as iron, cobalt, nickel and alloys thereof, the cup bottom of the cup body 1 is provided with a magnetic cup shaft 11 which is used for generating magnetic attraction to the magnetic conduction piece in the cutter assembly 2 so as to enable the cutter shaft 21 to stop rotating within a preset time when the nose assembly 4 is taken down, and the cutter assembly 2 is detachably assembled on the magnetic cup shaft 11.

In one embodiment, the magnetic cup shaft 11 is fixed on the bottom of the cup body 1 by a fixing element 12 penetrating through the bottom of the cup body 1 from bottom to top.

In one embodiment, the knife assembly 2 further comprises a bushing 24 fixed in the arbor shaft fixing hole 211, and the magnet cup shaft 11 is detachably connected with the bushing 24. The upper tail end of the magnetic cup shaft 11 is sleeved in the cutter shaft fixing hole 211 of the cutter shaft 21 through the shaft sleeve 24, the magnetic cup shaft 11 provides positioning for the cutter assembly 2 in the rotating process and generates magnetic attraction force when the machine head assembly 4 is taken down so as to enable the cutter shaft 21 to stop rotating rapidly. Preferably, the sleeve 24 and the knife shaft 21 are integrally formed.

In one embodiment, the magnetic conductor is disposed within the arbor 21, the sleeve 24, and/or the chopper 22; alternatively, the knife shaft 21, the sleeve 24 and/or the chopping knife 22 are made of the magnetic conduction member. That is, the magnetic attraction force can be generated between any part of the cutter assembly 2 and the magnetic cup shaft 11, so that the purpose of the magnetic cup shaft 11 that the cutter shaft 21 stops rotating rapidly within a preset time can be achieved.

In one embodiment, the magnetic cup shaft 11 is made of a permanent magnetic material, so that the magnetic cup shaft 11 generates a magnetic attraction force to the knife assembly 2 to realize a quick rotation stopping function of the knife assembly 2; alternatively, in one embodiment, the magnetic cup shaft 11 is made of a non-permanent magnetic material, and a magnet is provided on the magnetic cup shaft 11.
