Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a food processor with simple operation comprises a base 1 and a mixing cup 2 mounted on the base 1. The mixing cup 2 comprises an outer cup 4 with an outer comminution device 3 and an inner cup 6 with an inner comminution device 5 which is arranged inside the outer cup 4. The outer cup 4 is integrally connected with the base 1.

Referring to fig. 2, the inner side of the cup body of the outer cup 4 is provided with a plurality of projections 7 along the circumferential direction of the outer cup 4, and the plurality of projections 7 each extend axially along the outer cup 4. The lug 7 can play the role of turbulent flow in the outer cup piece 4, and the crushing effect of the outer crushing device 3 is enhanced. The lower extreme of a plurality of lugs 7 flushes, and the upper end height varies to when making edible material smash in outer cup 4, a plurality of lugs 7 reduce the resistance to eating material flow when realizing the vortex effect, reduce motor load.

Referring to fig. 3, 4 and 5, each of the bosses 7 includes a face block 71 and a back block 72, but the arc length of the face block 71 is smaller than that of the back block 72, and the rotation direction of the drive shaft 31 is from the face block 71 to the back block 72. If the arc length of the front piece 71 is longer than that of the back piece 72, the joint between the back piece 72 and the inner side of the cup body of the outer cup 4 is less likely to be impacted, and the food material is likely to accumulate. And the arc length of the facing block 71 is smaller than that of the back block 72, the food material can impact the facing block 71 and the back block 72 at the same time, and the food material accumulation is not easy to occur. The inner cup 6 comprises a base 8, an inner cup 9 and a cup holder 10 between the base 8 and the inner cup 9. The base 8 and the inner cup 9 are fixedly connected through screws, and the cup clamping seat 10 is extruded by the base 8 and the inner cup 9 to be fixedly connected with the base 8 and the inner cup 9. The inner cup 9 is provided with a plurality of ribs 11 protruding toward the inside of the inner cup 9 along the circumferential direction, thereby forming depressions 12 on the outer surface of the inner cup 9. The inner cup 6 further comprises an inner lid 13 which seals the inner cup 9. The arrangement of the inner cup cover 13 plays a role in separating the inner part of the inner cup 6 from the inner part of the outer cup 4, so that powder generated by grinding in the inner cup 6 is prevented from entering the outer cup 4 from the inner part of the inner cup 6, and the pollution to the inner part of the outer cup 4 is reduced. The inner cup cover 13 radially protrudes out of the inner cup body 9, the distance between the inner cup cover 13 and the outer cup piece 4 is X, X is more than 0 and less than or equal to 1mm, and preferably X =0.5mm. The inner cup cover 13 radially protrudes out of the inner cup body 9 and has a smaller distance with the outer cup body 4, so that the radial limit of the inner cup piece 6 can be realized by the matching of the outer cup body 4 and the inner cup cover 13. A plurality of grooves 14 which penetrate through the base 8 and the cup body clamping seat 10 along the axial direction of the inner cup piece 6 are arranged on the outer side of the base 8 and the outer side of the cup body clamping seat 10 along the circumferential direction. The recesses 14 and the projections 7 are in one-to-one correspondence so that the projections 7 can each be snapped into the corresponding recess 14, and the plurality of recesses 14 are aligned with the lower end of the corresponding projection 7. The projections 7 are snapped into the recesses 14 in the axial direction, so that the outer cup 4 and the inner cup 6 are fixed in the circumferential direction. The lower end of the projection 7 is close to the outer crushing apparatus 3 and the groove 14 corresponds to the lower end of the projection 7, so that the fitting portions of the plurality of grooves 14 and the plurality of projections 7 can be close to the outer crushing apparatus 3, and the circumferential fixing effect of the inner cup 6 and the outer cup 4 can be enhanced. Upon rotation of the drive shaft 31, the inner cup 6 has a tendency to follow the rotation of the drive shaft 31. Because the arc length of the facing block 71 is smaller than that of the back block 72, the width of the contact surface between the facing block 71 and the groove 14 is smaller than that of the contact surface between the back block 72 and the groove 14, and the guiding effect of the facing block 71 is smaller than that of the back block 72, so that the groove 14 is more difficult to cross the joint of the facing block 71 and the back block 72 along the rotation direction of the driving shaft 31 than against the rotation direction of the driving shaft 31, thereby enhancing the circumferential fixing effect of the outer cup 4 and the inner cup 6. The cup body clamping seat 10 is provided with mounting grooves 15 communicated with the grooves 14 on two side walls opposite to the grooves 14, and the cup body clamping seat 10 is provided with a circumferential cushion pad 16, two ends of which are clamped in the two mounting grooves 15 respectively and are tightly attached to the bumps 7. When the projection 7 snaps into the groove 14, the projection 7 abuts the circumferential cushion 16. During grinding, when the outer crushing device 3 drives the inner crushing device 5 to rotate, the outer cup piece 4 and the inner cup piece 6 tend to rotate relatively. The circumferential cushion 16 serves to prevent the protrusions 7 from colliding with the walls of the grooves 14 and to reduce wear and vibration of the outer and inner cups 4, 6. The cup holder 10 is provided with a stopper rod 17 integrally coupled with the cup holder 10 in the groove 14, and the circumferential cushion 16 is provided with a stopper groove 18 for the stopper rod 17 to be caught in. The limiting rod 17 is clamped in the limiting groove 18, and the installation strength of the circumferential cushion 16 and the groove 14 is enhanced.

Referring to figures 6 and 7, the rim of the base 8 is provided with a downwardly extending support ring 19, the outer grating device 3 being located within the support ring 19. The support ring 19 serves to support the inner cup 6 and to prevent the inner cup 6 from pressing against the drive shaft 31 and affecting the transmission of the drive shaft 31 and the inner crusher 5. The minimum distance between the outer crushing device 3 and the inner wall of the support ring 19 is D, D is more than or equal to 1mm and less than or equal to 3mm, and D =2mm is preferred. The minimum distance between the outer crusher 3 and the inner wall of the support ring 19 is too small, the outer crusher 3 easily hits the inner wall of the support ring 19 during operation. And the minimum distance between the outer crushing device 3 and the inner wall of the support ring 19 is too large, the working range of the outer crushing device 3 is small, and the crushing effect is poor. The lower end of the support ring 19 is integrally connected to a connecting portion 20 and a flange portion 21 in this order from the top. Wherein the flange portion 21 and the support ring 19 have the same outer diameter, and the connecting portion 20 has a smaller outer diameter than the flange portion 21. The lower end of the support ring 19 is provided with a bottom cushion 22, and the bottom cushion 22 is provided with a catch 23 into which the flange portion 21 is fitted. The groove wall on one side of the groove 23 abuts against the connecting portion 20, and the groove wall on the other side protrudes from the flange portion 21. The bottom cushion 22 is fixed to the support ring 19 by engagement of the catch 23 with the flange 21 and the connecting portion 20. And the arrangement of the bottom buffer cushion 22 avoids the collision of the support ring 19 directly contacting with the engine base 1, and reduces the abrasion and vibration of the support ring 19 and the engine base 1.

Referring to fig. 5, 6 and 8, inner cup lid 13 is provided with an annular sunken platform 24, and inner cup lid 13 is provided with a handle 25 at the center of annular sunken platform 24. The inner cup cover 13 can be axially fixed with the inner cup body 9 by adopting a lock catch structure, and the arrangement of the handle 25 is convenient for people to apply force to the inner cup cover 13, so that the inner cup piece 6 can be taken out from the outer cup piece 4. The length of the handle 25 can be prolonged by the arrangement of the annular sinking platform 24, so that people can conveniently grab the handle 25 stably, an anti-overflow electrode arranged on the outer cup cover 26 can be avoided, and a sealing structure for sealing the inner cup body 9 and the inner cup cover 13 can be installed at the annular sinking platform 24. An outer cup cover 26 for sealing the outer cup 4 is fixedly connected to the outer cup 4. The minimum distance between the outer cup cover 26 and the handle 25 is d, d is more than or equal to 0 and less than or equal to 3mm, and d =2mm is preferred. When the inner cup 6 moves upwards for a distance d, the handle 25 contacts with the outer cup cover 26, so that the axial position of the inner cup 6 is limited. The outer cap 26 is provided with an upper cap cushion 27 located at a minimum distance between the outer cap 26 and the handle 25. The arrangement of the upper cover buffer cushion 27 is used for avoiding collision between the handle 25 and the outer cup cover 26 when the handle 25 is contacted with the outer cup cover 26, and reducing abrasion and vibration of the handle 25 and the outer cup cover 26. The outer cap 26 is provided with a seal 28 which seals the junction of the outer cap 26 and the outer cup member 4. One end of the sealing element 28 protrudes out of the joint of the outer cup cover 26 and the outer cup piece 4 and is positioned above the inner cup cover 13, and the other end of the sealing element protrudes out of the joint of the outer cup cover 26 and the outer cup piece 4 and is clamped between the inner cup cover 13 and the outer cup piece 4. The sealing member 28 is located above the inner cup 6 so that when the inner cup 6 is moved upwardly, the inner cup 6 will contact the sealing member 28 and be retained by the sealing member 28. One end of the sealing element 28 is inserted between the inner cup cover 13 and the outer cup piece 4, so that the radial limiting effect of the inner cup cover 13 is achieved, the inner cup cover 13 is prevented from colliding with the outer cup piece 4, and the abrasion and the vibration of the inner cup cover 13 and the outer cup piece 4 are reduced. An annular groove 29 is formed in the circumferential outer side of the inner cup cover 13, and a lower cup buffer cushion 30 is arranged in the annular groove 29. The lower cover cushion pad 30 is positioned between the inner cup cover 13 and the outer cup piece 4, so that the inner cup cover 13 is prevented from colliding with the outer cup piece 4, and the abrasion and the vibration of the inner cup cover 13 and the outer cup piece 4 are reduced. When the sealing element 28 deforms along with the increase of the service time, one end of the sealing element 28 is difficult to insert between the inner cup cover 13 and the outer cup 4, and the lower cover buffer cushion 30 can replace the sealing element 28 to play a role in buffering.

Referring to fig. 9 and 10, the outer crushing apparatus 3 includes a driving shaft 31 and a lower blade 32 fitted around the driving shaft 31. The driving shaft 31 can be directly connected to and rotated by the motor, or can be connected to an output shaft of the motor to transmit the motion of the output shaft. The lower blade 32 includes an upper group 321 and a lower group 322. The surfaces of the upper lifting knife set 321 and the lower lifting knife set 322 are provided with pressure relief holes 333. When the outer cup 4 crushes the food, the food located under the lower blade 32 is ejected from the pressure release hole 333 by a large pressure generated by the lower blade 32. The drive shaft 31 is provided with a step 33, the lower blade 32 abuts against the step 33 of the drive shaft 31, and the drive shaft 31 is threadedly connected with a nut 34, the nut 34 and the drive shaft 31 pressing and fixing the lower blade 32. The lower connector 35 is screwed to the driving shaft 31 above the nut 34, and the pressure relief hole 333 of the upper raising blade set 321 is aligned with the lower connector 35. Since the pressure relief holes 333 of the upper raising blade set 321 are aligned with the lower connector 35, the food material ejected from the pressure relief holes 333 of the upper raising blade set 321 impacts the lower connector 35, thereby enhancing the turbulence effect. The lower connector 35 is provided with a fixing groove 36 screw-coupled with the driving shaft 31 and a receiving groove 37 wrapping the nut 34, and the fixing groove 36 and the receiving groove 37 communicate. The lower connector 35 is provided with a guide groove 38 communicating with the receiving groove 37, but the width of the guide groove 38 is larger than the width of the receiving groove 37. The junction of the guide groove 38 and the accommodation groove 37 is provided with an accommodation chamfer 39. The lower connector 35 is used for wrapping the nut 34, so that the situation that the driving shaft 31 in threaded connection with the nut 34 is polluted by food materials and the nut 34 is difficult to withdraw from the driving shaft 31 is reduced. The provision of the guide groove 38 and the receiving chamfer 39 makes it easier for the nut 34 to enter the receiving groove 37.

Referring to fig. 9 and 10, the inner crushing apparatus 5 includes an upper blade 40 and an upper connecting shaft 41. One end of the upper connecting shaft 41 is connected with the upper blade 40, and the other end is fixedly connected with an upper connector 42. The upper connector 42 is provided with a linking groove 43 at one end facing the lower connector 35, and the lower connector 35 is clipped into the linking groove 43. The lower connecting head 35 is clamped into the linkage groove 43 to realize the mechanical linkage of the upper connecting head 42 and the lower connecting head 35, and further realize the mechanical linkage of the inner crushing device 5 and the outer crushing device 3. If the lower connecting head 35 is provided with the linking groove 43 and the upper connecting head 42 is clamped in the linking groove 43, the opening of the linking groove 43 faces upwards, and at the moment, the food material is easy to fall into the gap between the linking groove 43 and the upper connecting head 42. And the linkage groove 43 is arranged on the upper connector 42, the food material is easy to fall into the linkage groove 43 under the action of self gravity. Referring to fig. 11, the notch of the interlocking groove 43 is provided with an interlocking chamfer 44 for guiding the lower connector 35 to be caught in the interlocking groove 43, thereby making it easier for the lower connector 35 to be caught in the interlocking groove 43. The interlocking groove 43 includes a positioning groove 45 distant from the notch of the interlocking groove 43 and a guide groove 46 near the notch of the interlocking groove 43. The groove wall of the guide groove 46 is provided with a plurality of guide slopes 47. The plurality of guide slopes 47 are in the same direction. The cross section of the positioning groove 45 is polygonal, preferably square, and the outer portion of the lower connector 35 is rectangular. The ratio of the height of the guide slope 47 to the depth of the interlocking groove 43 is 1. When the lower connector 35 abuts the guiding slope 47, the lower connector 35 is aligned with the positioning groove 45 and finally enters the positioning groove 45 under the guiding of the guiding slope 47 as the inner cup 6 slowly enters the inner part of the outer cup 4. If the height of the guide slope 47 is too high in the depth of the linkage groove 43, the depth of the positioning groove 45 is low, which is not favorable for circumferential linkage of the lower connector 35 and the upper connector 42; if the height is too low, the guiding effect of the guiding inclined surface 47 is poor, which is not favorable for the upper connector 42 or the lower connector 35 to be clamped into the positioning groove 45.

It can be understood that the upper end of the cup body clamping seat 10 extends to the rib 11, and the cup body clamping seat 10 is provided with a clamping block clamped in the recess 12.

It will be appreciated that inner cup cover 13 is eliminated and the minimum distance between outer cup cover 26 and inner cup 6 is 0, so that outer cup cover 26 can both limit axial movement of inner cup 6 and act to seal inner cup 6.

The outer cup 4 is provided with a self-cleaning function, and the inner cup 6 is provided with a polishing function. When the inner cup 6 is not needed, the inner cup 6 is removed from the outer cup 4. When the inner cup piece 6 is needed to be used, the inner cup piece 6 is loaded into the outer cup piece 4, and the driving shaft 31 is utilized to drive the inner crushing device 5 to rotate. Finally, the grinding function is realized while the self-cleaning function is realized.
