The bearing 353 is mounted on the shaft 352, the bearing 353 includes a flange 3531 and a joint section 3532, the stirring blade 351 is mounted at the upper end of the shaft 352, and the joint section 3532 has a protrusion 3533 at the lower end. The lower end of the shaft 352 has a driven end 3521. The locking member 354 has a barrel 3541 and a lever 3542, the lever 3542 extends outwardly from the outer side of the barrel 3541, and the inner side of the barrel 3541 has a fastening structure for engaging with the protrusion 3533. Such as an axial groove for passing the protrusion 3533 in the axial direction and a circumferential groove for engaging with the protrusion 3533 when the cylinder 3541 is rotated in the circumferential direction, the axial groove and the circumferential groove may be communicated with each other; the circumferential groove can be defined by a horizontal surface that can also be modified to a gradually decreasing surface to gradually compress as the nub 3533 rotates along the surface to fixedly mount the blending knife assembly 35 to the cup 31. The bearing 353 can be inserted into the opening 321 of the heat-generating plate 32, the through hole 391 of the base 39 and the cylinder 3541 in sequence, so that the flange 3531 abuts against the heat-generating plate 32 of the cup body, and the joint section 3532 is jointed with the opening 321 of the heat-generating plate 32 in a manner of preventing the bearing 353 from rotating. The shifting lever 3542 is shifted to drive the cylinder 3541 to rotate, so that the protrusion 3533 at the lower end is matched with the fastening structure, and the stirring knife assembly 35 is locked on the cup body 31. By reversing the toggle 3542, the barrel 3541 can be rotated such that the protrusion 3533 disengages from the fastening structure, thereby removing the portion of the blending tool set 35 other than the barrel 3541 and the retainer 355 from the cup 31.

The lid 37 is adapted to engage the handle 38 and cover the opening 311 of the cup 31. Lid 37 may include a lid body 371, a sealing ring 372, and a spill-resistant cover 373. Lid body 371 may also include lid handle 3712. The seal 372 is used to form a seal between the lid 37 and the opening 311 of the cup 31 when the lid 37 is fitted on the handle 38. The lid 37 is provided at a central portion thereof with a through hole 3711 to allow steam to be discharged when food in the cup 31 is heated. The overflow preventing cap 373 may be further inserted into the through hole 3711. The spill-proof cap 373 may be a hollow cylinder with a top so as to be able to function as a measuring cup.

The handles 38 may be two and fixed to two opposite sides of the cup 31, respectively. Each handle 38 may include a handle body 381 and a handle cover 382. Within the handle 38 are a link 383 and a catch 384. Cap 37 may fit within a detent of handle 38, for example, via a detent thereon, and when cap 37 fits on handle 38, cap 37 may also urge link 383 to move in a first direction (e.g., downward), via the detent, and movement of link 383 may also urge catch 384 to move in a second direction perpendicular to the first direction. It should be noted that the movement of the locking member 384 in the second direction is not limited to the movement of the locking member 384 in the second direction as a whole, and the movement of the locking member 384 may have a component along the second direction. For example, the movement of the link 383 can cause the latch 384 to pivot, and since the pivoting movement of the latch 384 has a component in the second direction, the pivoting of the latch 384 should also be within the range of movement of the latch 384 in the second direction. For another example, the catching block may have an inclined surface so that the inclined surface may gradually press the upper end of the link 383 down when the cap 37 is engaged with the catching groove of the handle 38 by rotation, thereby moving the link 383 down; the link 383 can also directly or indirectly engage the catch 384 to urge the lower end of the catch 384 to protrude to the left or right of the handle 38 while the link 383 moves down. The link 383 and catch 384 can each be held in a stable position by, for example, a spring, move only when actuated, and each return to the original stable position by the spring when the actuation force is removed.

Referring back to fig. 1 and 2, the conductive pins 337 are inserted into the sockets 12 when the food processing cup 30 is mounted on the housing 10. Therefore, the conductive pin 337 can lead out the temperature signal measured by the temperature sensor 333 and transmit the temperature signal to the control circuit in the base 10; moreover, the conductive pins 337 can also supply current to the heating plate 32 to heat the food material in the food processing cup 30. In addition, when the food processing cup 30 is mounted on the housing 10 and when the cap 37 is engaged on the handle 38, the cap 37 urges movement of the link 383 in the first direction to cause the link 383 to depress the microswitch 14, and the catch 384 moves in the second direction to snap-engage with the catch 15 to secure the food processing cup 30 on the housing 10. The microswitch 14 can be used for controlling the on-off of an internal circuit of the machine base 10, and when the microswitch 14 is pressed by the connecting rod 383 to be closed, the microswitch 14 controls the conduction of the internal circuit of the machine base 10 to realize the functions of heating, stirring and the like; when the food processing cup 30 is taken down, the internal circuit of the machine base 10 is controlled to be automatically disconnected by the micro switch, so that the functions of automatically powering off after the food processing cup 30 is taken down and the like are realized, and the safety factor of the cooker is improved. The catching groove 15 may be a hole opened on a sidewall of the receiving space 11 so as to receive a portion of the catching member 384 and thereby restrict the food processing cup 30 from moving in a direction away from the housing 10 when the catching member 384 moves; of course, the engaging groove 15 may be modified to a baffle structure as long as it can limit the movement of the food processing cup 30 in a direction away from the housing 10 when engaging with a portion of the engaging member 384. In addition, the micro switch 14 may be provided in two and on both sides of the accommodating space 11, and the card slot 15 may be provided in two and on both sides of the accommodating space 11, corresponding to the number of the handles 38. The control panel 16 disposed on the base 10 can be used for controlling the operation of the food processor 100 through touch control operation, and the control panel 16 can be changed into a mechanical knob or a button. The base 10 may be provided therein with a driving motor, which can drive the driven end 3521 of the shaft 352 of the stirring blade set 35 to rotate through the transmission wheel 17 when the microswitch 14 is pressed to conduct a circuit, so as to drive the stirring blade 351 to rotate in the food processing cup 30. The driving motor can be directly meshed with the driving wheel 17, and can also drive the driving wheel 17 to rotate through a middle driving wheel and/or a belt and the like.

The food processing cup 30 and housing 10 may also include other necessary components to perform their functions, which are well known to those skilled in the art and will not be described further herein.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
