Referring to fig. 1 to 8, the food processor 800 includes a main body 500, a stirring cup assembly 300 and a cup cover assembly 400. The blending cup assembly 300 is detachably mounted to the main body 500. The cup cover assembly 400 covers the stirring cup assembly 300.

The main machine 500 comprises a shell 51 and a motor 52 arranged in the shell 51; the stirring cup assembly 300 is detachably mounted on the main machine 500, the stirring cup assembly 300 comprises a stirring cup 10 and a stirring cutter disc assembly 20 detachably mounted at the bottom of the stirring cup 10, the stirring cutter disc assembly 20 comprises a chassis 21 and a cutter assembly 23, and the cutter assembly 23 comprises a cutter shaft 231 penetrating through the chassis 21 and a cutter blade 232 fixed on the cutter shaft 231; the output end of the motor 52 is provided with a magnetic driving member, and the magnetic driving member is magnetically matched with the knife assembly 23 and drives the knife assembly 23 to rotate.

Because stirring cutter head assembly 20 detachably installs in stirring cup 10 bottom, when stirring cup subassembly 300 used the back and need wash, will stir cutter head assembly 20 and dismantle, convenient operation, and wash thoroughly, so, stirring cutter head assembly 20 no longer has unable abluent dead angle, has effectively avoided breeding the bacterium, has produced the condition of peculiar smell.

The stirring cup assembly 300 further comprises a fixing member 30, and the stirring cutter disc assembly 20 is detachably mounted at the bottom of the stirring cup 10 through the fixing member 30. Therefore, the stirring cutter head assembly 20 is arranged at the bottom of the stirring cup 10 through the fixing piece 30, and the stirring cutter head assembly is stable, reliable and simple in structure.

The fixing member 30 is rotatably installed at the bottom of the mixing cup 10, the fixing member 30 is switched between an open position and a locked position by rotation, when the fixing member 30 is located at the open position, the mixing cutter head assembly 20 is detachably installed at the bottom of the mixing cup 10, and when the fixing member 30 is switched to the locked position, the fixing member 30 fixes the mixing cutter head assembly 20 to the mixing cup 10 and seals the bottom of the mixing cup 10. Therefore, the fixing part 30 is rotated, so that the stirring cutter head assembly 20 can be mounted and dismounted, and the operation is convenient.

The stirring cup assembly 300 further comprises two locking assemblies 60 mounted at the bottom of the stirring cup 10, and the two locking assemblies 60 are respectively in locking fit with the fixing member 30, so as to fix the stirring cutter head assembly 20 to the stirring cup 10 and seal the bottom of the stirring cup 10. So, through two hasp subassemblies 60 and the cooperation of mounting 30, with the dual locking in stirring cup 10 bottom of stirring cutter head subassembly 20, in the cooking machine use, the difficult pine of stirring cutter head subassembly 20 takes off safe and reliable to two hasp subassemblies 60 can effectively prevent to open the potential safety hazard that one of them caused by the human maloperation.

The first locking part 611 is located at one end of the first locking part 61, and the mating triggering part 612 is located at the other end of the first locking part 61. When the key 64 is pressed, the triggering portion 641 presses the matching triggering portion 612, so that the first locking member 61 rotates outward and is separated from the fixing member 30. Thus, the locked state between the first latch 61 and the fixed member 30 can be released by operating the push button 64.

The triggering portion 641 and the matching triggering portion 612 are disposed at an interval, and when the key 64 is pressed until the key 64 is disengaged from the second locking member 62, the triggering portion 641 does not press the matching triggering portion 612. At this time, the locking between the second locking member 62 and the fixing member 30 is released, and the first locking member 61 and the fixing member 30 are still in the locked state. Thus, the fixing member 30 can be more reliably locked by the locking assembly 60, and the locking assembly 60 is effectively prevented from being opened due to misoperation.

When the key 64 is further pressed, the triggering portion 641 presses the matching triggering portion 612 until the lock between the first locking member 61 and the fixing member 30 is released. At this time, the first and

second locking members

61 and 62 are all unlocked from the fixing member 30, and the stirring blade assembly 20 can be detached.

The matching triggering portion 612 extends into the sliding slot, and the matching triggering portion 612 corresponds to the triggering portion 641 of the key 64. The engagement triggering portion 612 is further provided with an escape groove 613 engaged with the second elastic member 65.

When the key 64 is pressed, the key 64 compresses the second elastic member 65 and slides downward until the first position-limiting portion 643 and the second position-limiting portion 622 are disengaged, the second locking member 62 rotates outward under the elastic force of the first elastic member 63, so that the locking between the second locking portion 621 and the second engaging locking portion 32 is disengaged. At this time, the first locking piece 61 is still in a state of locking the fixing member 30. Therefore, if the second locking member 62 is opened by pressing the button 64 by mistake, the first locking member 61 is still locked with the fixing member 30, and the operation is safe and reliable.

The key 64 is continuously pressed downward, so that the triggering portion 641 of the key 64 presses the matching triggering portion 612, and the first locking member 61 rotates outward and releases the locking with the fixing member 30. Thus, the locking between the locking assembly 60 and the fixing member 30 is completely released, and the stirring cup assembly 300 can be disassembled for cleaning.
