The first receiving sleeve 113 may include a guide section 1131, a main body section 1132, and a coupling section 1133; the guide section 1131 has a guide hole slightly larger than the upper end of the temperature sensing element 201, and the main body section 1132 has a guide hole slightly larger than the first elastic member 203. During assembly, the temperature sensing element 201 is disposed in the first receiving sleeve 113, and the upper end of the temperature sensing element 201 is inserted into the guide section 1131 and exposed from the top of the first receiving sleeve 113; the first fixing block 202 can be connected with the coupling section 1133 and installed at the bottom of the first receiving sleeve 113, so as to prevent the temperature sensing element 201 from falling off from the first receiving sleeve 113; the first elastic member 203 can be located in the guide hole of the main body section 1132. The first fixing block 202 can be provided with a sleeve extending toward the temperature sensing element 201, so as to receive the lower end of the first elastic member 203, so as to stabilize the first elastic member 203.
[0035] A safety device 21 may also be provided on the machine base 10, and the safety device 21 is arranged on the bottom wall 111 of the accommodating space 11; when the food processing cup 30 is installed on the machine base 10, the safety device 21 abuts against the heating component 32 arranged on the bottom 310 of the cup body 31, and can disconnect the power supply circuit of the heating component 32 when the temperature threshold is reached.
[0036] See also Figures 5 and 6, a second receiving sleeve 114 is also provided on the bottom wall 111 of the receiving space 11. The second receiving sleeve 114 may extend from the bottom wall 111 into the receiving space 11. The second receiving sleeve 114 may be integrally formed with the bottom wall 111, or may be a separate component mounted on the bottom wall 111. The safety device 21 may include a safety element 211, a second fixing block 212, and a heat-conducting cover 213. The safety device 21 may also include a positioning block 214 and a second elastic member 215. The second receiving sleeve 114 may include a guide section 1141 and a main body section 1142; the guide section 1141 has a guide hole slightly larger than the upper end of the heat-conducting cover 213, and the main body section 1142 has a guide hole slightly larger than the second elastic member 215. The safety element 211 is arranged in the heat-conducting cover 213, and the heat-conducting cover 213 is arranged in the second receiving sleeve 114. The upper end of the heat-conducting cover 213 can be inserted into the guide section 1141 of the second receiving sleeve 114 and exposed from the top of the second receiving sleeve 114; the second fixing block 212 can be installed at the bottom of the second receiving sleeve 114 to prevent the heat-conducting cover 213 from falling off from the second receiving sleeve 114. The heat-conducting cover 213 can be made of metal material, and its top can have a flat surface to contact with the heating component 32 as much as possible to transfer heat. The safety element 211 can be a thermostat or a fuse. When a thermostat is used, if the temperature of the heating component 32 is higher than the first temperature threshold, the thermostat can be automatically disconnected to stop the heating component 32 from being energized and generating heat; when the temperature of the heating component 32 is lower than the first temperature threshold, the thermostat can automatically return to the on state to allow the heating component 32 to continue to be energized and generate heat. When a fuse is used, if the temperature of the heating component 32 is higher than the second temperature threshold (the second temperature threshold may be higher than the first temperature threshold), the fuse may be automatically blown to avoid damage or safety accidents caused by the excessive temperature of the heating component 32. The positioning block 214 may hold the fuse element 211 and be arranged in the heat-conducting cover 213; the second elastic member 215 may be arranged between the second fixing block 212 and the positioning block 214, and apply elastic thrust to the second fixing block 212 and the positioning block 214, so that the heat-conducting cover 213 elastically abuts against the heating component 32. The first elastic member 203 and the second elastic member 215 may be springs, elastic rubbers, etc. The top of the second fixing block 212 may be provided with a boss, and the lower side of the positioning block 214 may also be provided with a boss, so that the two bosses are respectively inserted into the openings at both ends of the second elastic member 215, thereby achieving a stabilizing effect on the second elastic member 215, that is, the elastic member 215 can only be extended and retracted in the axial direction, and will not move in a direction deviating from the axial direction.
[0037] See also Figures 7 to 11 , shows a food processing cup 30 provided in one embodiment of the present invention.
[0038] The heating component 32 may be a heating tube, which may be arranged in a ring shape and have a first end 321 and a second end 322 close to each other. The two power pins 34 are respectively connected to the first end 321 and the second end 322 of the heating tube, and extend in a direction away from the bottom 310 of the cup body 31. When the food processing cup 30 is mounted on the machine base 10, the power pin 34 is inserted into the power socket 13. Since the number of the power pins 34 is two, the number of the power sockets 13 is also two. Of course, the bottom 310 of the cup body 31 may also be provided with a grounding pin, and a corresponding grounding socket is provided on the machine base 10. The first end 321 and the second end 322 are conductive components and may be welded to the two power pins 34. In addition, the diameters of the first end 321 and the second end 322 may be set so that they have sufficient strength (for example, a diameter of about 2 mm to about 5 mm) to stabilize the power pins 34 welded thereon. Of course, the two power pins 34 can also be fixed to the bottom 310 of the cup body 31 in other ways so as to be stably plugged into and matched with the power socket 13 on the base 10 .
[0039] Return to see Figure 8 and Fig. 9, the thermometer 331 may be a temperature sensor such as a thermistor, the thermometer fixing part 332 may be a fixing glue with a certain elasticity or other elastic or non-elastic body, and the metal box 334 and the bottom 310 of the cup body 31 may be made of stainless steel. Of course, the metal box 334 may also be made of other suitable metal materials, as long as it can be fixed or welded to the bottom 310 of the cup body 31; in addition, the metal box 334 may be a box-shaped container, the top of which may be open so as to be fixed or welded to the bottom 310 of the cup body 31, and the bottom of which may be provided with a small opening so as to allow the thermometer pin 333 to extend from the metal box 334; it is easy to understand that the shape of the metal box 334 may be in various forms, as long as it can accommodate the thermometer 331 and the thermometer fixing part 332 and be fixed to the bottom 310 of the cup body 31. The metal box 334 can be sealed and welded to the bottom 310 of the cup body 31 by, for example, laser welding; in other words, the metal box 334 can be connected to the bottom 310 of the cup body 31 by a welding structure W. Of course, the metal box 334 can also be fixed to the bottom 310 of the cup body 31 by, for example, screws, and a sealing material can be applied to the part where the metal box 334 and the bottom 310 are combined to achieve fixation and sealing; in addition, in order to ensure the sealing effect, a sealing material can be applied to the welding structure W. The heating component 32 can be a sealed waterproof structure, so that the other energized heating parts of the heating component 32 except for the two power pins 34 that need to be electrically connected to the two power pins 34 are surrounded by the waterproof structure. The metal box 334 can seal the thermometer 331 between the metal box 334 and the bottom 310 of the cup body 31 through sealing material; that is, while the metal box 334 and the bottom 310 of the cup body 31 are sealed by welding, other parts of the metal box 334 are also provided with sealing material at locations that may be permeable to water (for example, an opening opened on the metal box 334 to allow the thermometer pin 333 to extend from the metal box 334), so that all the components housed in the metal box 334 are sealed and will not come into contact with liquids such as water.
[0040] The two ends 3311 and 3312 of the thermistor can be respectively connected to the two temperature detector pins 333 by direct welding or by a wire in the middle. The two temperature detector pins 333 can also be fixed by a pin fixing block 335, and the pin fixing block 335 can be installed in the metal box 334 by screws 336, for example.
[0041] See also Figure 7 , Figure 8 and Fig.10, the mixing knife set 35 is installed at the bottom 310 of the cup body 31. The mixing knife set 35 may include a mixing knife 351, a shaft 352, a bearing 353, a locking member 354 and a retaining member 355. The bearing 353 is installed on the shaft 352, and the bearing 353 includes a flange 3531 and a joint section 3532. The mixing knife 351 is installed at the upper end of the shaft 352, and the lower end of the joint section 3532 has a protrusion 3533. The upper end of the shaft 352 has a driven end 3521. The locking member 354 has a barrel 3541 and a lever 3542, and the lever 3542 extends outward from the outer side of the barrel 3541, and the inner side of the barrel 3541 has a fastening structure for cooperating with the protrusion 3533. The fastening structure is, for example, an axial groove for the protrusion 3533 to pass axially and a circumferential groove for cooperating with the protrusion 3533 when the cylinder 3541 is rotated circumferentially. The axial groove and the circumferential groove can be mutually connected; the circumferential groove can be defined by a horizontal surface, and the horizontal surface can also be changed to a gradually lowered surface so that the protrusion 3533 is gradually compressed along the rotation of the surface, so that the mixing knife group 35 can be fixedly installed on the bottom 310 of the cup body 31. The retaining member 355 can be installed on the bottom cover 36 and is used to cooperate with the locking member 354 to prevent the locking member 354 from falling off the bottom cover 36. The bearing 353 can be inserted into the opening 312 of the bottom 310 in sequence (see Fig.11 ), the through hole 365 of the bottom cover 36 and the barrel 3541, so that the flange 3531 abuts against the bottom 310 of the cup body 31, and the engagement section 3532 engages with the opening 312 of the bottom 310 in a manner to prevent the bearing 353 from rotating. By toggling the lever 3542 to drive the barrel 3541 to rotate, the protrusion 3533 at the lower end cooperates with the fastening structure, thereby locking the mixing knife group 35 on the cup body 31. By toggling the lever 3542 in the opposite direction, the barrel 3541 can be rotated so that the protrusion 3533 is out of cooperation with the fastening structure, thereby removing the mixing knife group 35 except the barrel 3541 and the retaining member 355 from the cup body 31.
[0042] See also Figure 7 and Figure 8 The bottom cover 36 may be fixed to the bottom 310 of the cup body 31 or to a portion of the cup body 31 close to the bottom 310. The bottom cover 36 may include an annular inner wall 361 and an annular outer wall 362, the annular inner wall 361 and the annular outer wall 362 enclose a space 363 for accommodating the heat generating component 32, and the thermometer pin 333 extends into the space 364 enclosed by the annular inner wall 361. The portion of the bottom cover 36 defining the through hole 365 may be provided with a plurality of openings so that the thermometer pin 333 and the power pin 34 can pass therethrough.
[0043] The cup cover 37 is used to cooperate with the handle 38 and cover the opening 311 of the cup body 31. The cup cover 37 may include a cup cover body 371, a sealing ring 372 and an anti-overflow cover 373. The cup cover body 371 may also include a cup cover handle 3712. The sealing ring 372 is used to form a seal between the cup cover 37 and the opening 311 of the cup body 31 when the cup cover 37 is matched on the handle 38. The cup cover 37 is provided with a through hole 3711 at its central part to allow steam to be discharged when the food in the cup body 31 is heated. The anti-overflow cover 373 may also be inserted into the through hole 3711. The anti-overflow cover 373 may be a hollow cylinder with a top so that it can be used as a measuring cup.
[0044] The handle 38 may be two and fixed to two opposite sides of the cup body 31, respectively. Each handle 38 may include a handle body 381 and a handle cover 382. A connecting rod 383 and a fastener 384 are provided in the handle 38. The cup cover 37 may, for example, be fitted into the slot of the handle 38 through a card block thereon. When the cup cover 37 is fitted on the handle 38, the cup cover 37 may also cause the connecting rod 383 to move in a first direction (e.g., downward direction) through the card block, and the movement of the connecting rod 383 may also cause the fastener 384 to move in a second direction perpendicular to the first direction. It should be noted that the movement of the fastener 384 in the second direction described herein is not limited to moving the fastener 384 as a whole in the second direction, but only to causing the movement of the fastener 384 to have a component along the second direction. For example, the movement of the connecting rod 383 can cause the catch 384 to pivot, and since the pivotal movement of the catch 384 has a component along the second direction, the pivoting of the catch 384 should also belong to the range of the movement of the catch 384 in the second direction. For another example, the block may have an inclined surface so that when the cup cover 37 is rotated to cooperate with the slot of the handle 38, the inclined surface can gradually press down the upper end of the connecting rod 383, so that the connecting rod 383 moves downward; the connecting rod 383 can also be directly or indirectly engaged with the catch 384, so that when the connecting rod 383 moves downward, the lower end of the catch 384 is caused to protrude to the left or right side of the handle 38. The connecting rod 383 and the catch 384 can each be maintained in a stable position by, for example, a spring, and only move when actuated, and when the actuating force is canceled, they each return to the original stable position by a spring.
[0045] Return to see Figure 1 and Figure 2When the food processing cup 30 is mounted on the base 10, the thermometer pin 333 can be inserted into the thermometer socket 12, and the power pin 34 can be inserted into the power socket 13. Thus, the thermometer pin 333 can lead out the temperature signal measured by the thermometer 331, and then transmit it to the control circuit in the base 10; and the power pin 34 can transmit current from the power socket 13 to the heating component 32, so that the heating component 32 generates heat to heat the bottom 310 of the cup body 31, and then heat the food in the food processing cup 30. In addition, when the food processing cup 30 is mounted on the base 10 and when the cup cover 37 is engaged with the handle 38, the cup cover 37 causes the connecting rod 383 to move in the first direction, so that the connecting rod 383 can press the micro switch 14, and the buckle 384 moves in the second direction and buckles with the card slot 15 to fix the food processing cup 30 on the base 10. The micro switch 14 can be used to control the on and off of the internal circuit of the base 10. When the micro switch 14 is pressed and closed by the connecting rod 383, the micro switch 14 controls the internal circuit of the base 10 to be turned on, realizing functions such as heating and stirring; when the food processing cup 30 is removed, the micro switch controls the internal circuit of the base 10 to be automatically disconnected, realizing functions such as automatic power off after the food processing cup 30 is removed, thereby improving the safety factor of the cooker. The card slot 15 can be a hole opened on the side wall 112 of the receiving space 11, so that when the card fastener 384 moves, it can accommodate a part of the card fastener 384 and thereby limit the food processing cup 30 from moving in a direction away from the base 10; of course, the card slot 15 can also be changed to a baffle structure, as long as it can limit the food processing cup 30 from moving in a direction away from the base 10 when it cooperates with a part of the card fastener 384. In addition, corresponding to the number of handles 38, there can also be two micro switches 14 and they are arranged on both sides of the receiving space 11, and there can also be two card slots 15 and they are arranged on both sides of the receiving space 11. The control panel 16 provided on the base 10 can be used to control the operation of the food processor 100 through touch operation, and the control panel 16 can also be changed into a mechanical knob or button. A driving motor can be provided in the base 10. When the micro switch 14 is pressed to conduct the circuit, the driving motor can drive the driven end 3521 of the shaft 352 of the stirring knife group 35 to rotate through the transmission wheel 17, thereby driving the stirring knife 351 to rotate in the food processing cup 30. The driving motor can be directly engaged with the transmission wheel 17, or can drive the transmission wheel 17 to rotate through an intermediate transmission wheel and / or belt.
[0046] The food processing cup 30 and the base 10 may further include other necessary components to realize their functions, which are well known to those skilled in the art and will not be described in detail herein.
