Referring to fig. 1 to 8, 12 and 14, the food processing machine includes a main machine 1 and a food processing cup 2. The host 1 comprises a machine head 11, an upper adsorption piece 13 and a motor 141, wherein the upper adsorption piece 13 and the motor 141 are arranged on the machine head 11, and the motor 141 drives the upper adsorption piece 13 to rotate. The cooking cup 2 comprises a crushing cup 21 and a stirring device 22. The stirring device 22 includes a cutter shaft 221, a suction member 222 and a stirring member 223 disposed on the cutter shaft 221. The stirring member 223 is positioned in the pulverizing cup 21. The host 1 further comprises a coil 142, a control board 143, a first detection switch 144 and a trigger 145. The cuisine cup 2 can move between a first position and a second position when assembled to the host 1. When in the first position, the cooking cup 2 presses the trigger piece 145, the trigger piece 145 moves to trigger the first detection switch 144, and the control board 143 receives a signal sent by the first detection switch 144 to control the coil 142 to be electrified so as to reduce or eliminate the magnetic attraction between the upper suction piece 13 and the lower suction piece 222; in the second position, the stirring device 22 is driven to rotate by the magnetic attraction between the upper adsorbing member 13 and the lower adsorbing member 222.

In some embodiments, when the trigger 145 and the first detection switch 144 of the above-mentioned technical solution are disposed, the trigger 145 is pressed by the cooking cup 2 when the cooking cup 2 is in the first position, the trigger 145 moves to trigger the first detection switch 144, the control board 143 controls the coil 142 to be energized, so as to reduce or eliminate the magnetic attraction between the upper suction member 13 and the lower suction member 222, and the magnetic attraction between the upper suction member 13 and the lower suction member 222 is small or even none, so that the cooking cup 2 is easier to be assembled; meanwhile, the magnetic force is reduced, so that the automatic centering of the upper adsorption piece 13 and the lower adsorption piece 222 is facilitated, concentricity index is improved, and noise caused by the eccentricity of the upper adsorption piece 13 and the lower adsorption piece 222 in the working process of the cooking machine can be reduced.

The food processor drives the stirring device 22 to rotate through the magnetic attraction between the upper adsorption piece 13 and the lower adsorption piece 222, the rotation of the motor 141 is not influenced by the stopping of the stirring device 22, and the motor 141 can idle, so that even if the stirring device 22 is blocked and cannot rotate, the motor 141 can still rotate normally, the damage of the motor 141 caused by the excessively high temperature rise due to the blocked rotation is effectively prevented, and the motor 141 is effectively protected; meanwhile, the concentricity requirement of the stirring device 22 is not high, and the position can be automatically corrected during high-speed operation; furthermore, the upper clutch and the lower clutch are not arranged, so that noise in the working process of the food processor is effectively reduced.

The magnetic force between the upper absorbing member 13 and the lower absorbing member 222 satisfies the torque of 0.05n.m or more when rotating, so as to ensure that the motor 141 can drive the stirring device 22 to rotate, so as to stir the food materials. Because the torque between the upper suction member 13 and the lower suction member 222 is relatively large, when the cuisine cup 2 is assembled to the main machine 1, the magnetic attraction between the upper suction member 13 and the lower suction member 222 needs to be reduced or eliminated, so that the cuisine cup 2 can be easily pushed in and the centering of the upper suction member 13 and the lower suction member 222 can be ensured.

Optionally, the upper absorbing member 13 and the lower absorbing member 222 are electromagnets or magnets or made of materials that can be magnetically absorbed.

The host 1 further comprises a resilient member 146. The elastic member 146 is pressed when the trigger 145 moves.

The magnetic attraction between the upper attraction member 13 and the lower attraction member 222 is recovered, and the motor 141 can drive the stirring device 22 to rotate so as to stir the food.

In some embodiments, the above technical solution resets through the trigger 145, so that the control board 143 controls the coil 142 to be powered off, and when the cooking cup 2 moves to the second position, the coil 142 is powered off, so that compared with the use of a control program, the power-on time of the coil 142 can be flexibly controlled, the coil 142 is prevented from being powered on for a long time, and the service life of the coil 142 is prolonged.

Alternatively, the trigger 145 may not be reset when in the second position, the energizing time of the coil 142 may be set by a program, and when the energizing time of the coil 142 reaches a threshold value, the control board 143 controls the coil 142 to be de-energized to restore the magnetic attraction force between the upper attraction member 13 and the lower attraction member 222; meanwhile, the coil 142 may be protected, since long-time energization may cause the temperature rise of the coil 142 to rise, and the coil 142 may burn out. Alternatively, the energizing time of the coil 142 is 1 minute or less, preferably within 1 to 20 seconds.

In some embodiments, the first detection switch 144, the elastic member 146, the triggering member 145 and the bracket 147 in the above technical solution are easy to assemble, so as to improve the assembly efficiency.

When the trigger 145 is reset, the tip of the crimp post 1451 protrudes from the through hole 1213 and protrudes from the top plate 1211, and the limit portion 1452 abuts against the top plate 1211; when the cuisine cup 2 is assembled to the main machine 1, the crushing cup 21 is pressed against the pressing post 1451, the pressing post 1451 is forced to move downwards and press against the elastic piece 146, so that the triggering part 1453 contacts the first detection switch 144 to trigger the first detection switch 144; when the compression force is lost, the elastic force of the elastic member 146 pushes up against the limiting portion 1452, so that the compression column 1451 moves upward to return.
