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 includes a base 1 and a stirring cup 2 mounted on the base 1. The stirring cup 2 comprises an outer cup 4 with an outer comminution means 3 and an inner cup 6 with an inner comminution means 5 and mounted inside the outer cup 4. The outer cup 4 is integrally connected with the machine 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 along the axial direction of the outer cup 4. The protruding blocks 7 can play a role in turbulence in the outer cup 4, and the crushing effect of the outer crushing device 3 is enhanced. The lower ends of the plurality of protruding blocks 7 are flush, and the heights of the upper ends are unequal, so that when food materials are crushed in the outer cup 4, the plurality of protruding blocks 7 achieve the turbulence effect, simultaneously reduce the resistance to the flow of the food materials, and reduce the load of a motor.

Referring to fig. 3, 4 and 5, each of the projections 7 includes a facing block 71 and a rear block 72, but the arc length of the facing block 71 is smaller than the arc length of the rear block 72, and the rotation direction of the drive shaft 31 is from the facing block 71 to the rear block 72. If the arc length of the facing block 71 is longer than that of the back block 72, the junction between the back block 72 and the inner side of the cup body of the outer cup 4 is hard to be impacted, and the food materials are easily accumulated. When the arc length of the facing block 71 is smaller than that of the back block 72, the food material simultaneously impacts the facing block 71 and the back block 72, and food material accumulation is not easily caused. 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 inward 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 member 6 also includes an inner cup lid 13 that seals the inner cup 9. The inner cup cover 13 plays a role in separating the inner cup member 6 from the outer cup member 4, so that powder generated by grinding in the inner cup member 6 is prevented from entering the outer cup member 4 from the inner cup member 6, and pollution to the inner cup member 4 is reduced. The inner cup cover 13 radially protrudes from the inner cup body 9, and the distance between the inner cup cover 13 and the outer cup member 4 is X, wherein X is more than 0 and less than or equal to 1mm, and preferably X=0.5 mm. The inner cup cover 13 protrudes radially from the inner cup body 9 and has smaller distance with the cup body of the outer cup member 4, so that the radial limit of the inner cup member 6 can be realized by means of the cooperation of the cup body of the outer cup member 4 and the inner cup cover 13. The outer side of the base 8 and the outer side of the cup holder 10 are provided with a plurality of grooves 14 penetrating the base 8 and the cup holder 10 in the axial direction of the inner cup 6 in the circumferential direction. The grooves 14 and the projections 7 are in one-to-one correspondence so that the projections 7 can each be caught in the corresponding groove 14, and the plurality of grooves 14 are aligned with the lower ends of the respective projections 7. The circumferential fixation of the outer cup 4 and the inner cup 6 is achieved by means of the lugs 7 being snapped into the grooves 14 in the axial direction. The lower ends of the projections 7 are close to the outer pulverizing device 3, and the grooves 14 correspond to the lower ends of the projections 7, so that the mating portions of the grooves 14 and the projections 7 can be close to the outer pulverizing device 3, thereby enhancing the circumferential fixing effect on the inner cup 6 and the outer cup 4. As the drive shaft 31 rotates, the inner cup 6 has a tendency to rotate along the drive shaft 31. Since the arc length of the facing block 71 is smaller than the arc length of the back block 72, the width of the joint surface between the facing block 71 and the groove 14 is smaller than the width of the joint surface between the back block 72 and the groove 14, and the guiding effect of the facing block 71 is smaller than the guiding effect of the back block 72, so that the groove 14 is harder to cross the joint between 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 two opposite side walls of the cup body clamping seat 10 are respectively provided with a mounting groove 15 communicated with the groove 14, and the cup body clamping seat 10 is provided with a circumferential buffer pad 16 of which the two ends are respectively clamped into the two mounting grooves 15 and are clung to the protruding blocks 7. When the lugs 7 are snapped into the grooves 14, the lugs 7 abut the circumferential cushion 16. While during grinding, when the outer grinding device 3 drives the inner grinding device 5 to rotate, the outer cup 4 and the inner cup 6 have a relative rotation tendency. The circumferential cushion 16 serves to avoid collision of the lugs 7 with the walls of the grooves 14 and to reduce wear and vibration of the outer cup 4 and the inner cup 6. The cup holder 10 is provided with a limit lever 17 integrally connected with the cup holder 10 in the groove 14, and the circumferential cushion pad 16 is provided with a limit groove 18 for the limit lever 17 to be caught. The limiting rod 17 is clamped into the limiting groove 18, so that the mounting strength of the circumferential cushion pad 16 and the groove 14 is enhanced.

Referring to fig. 6 and 7, the rim of the base 8 is provided with a downwardly extending support ring 19, and the external comminution means 3 is located within the support ring 19. The support ring 19 serves to support the inner cup 6 and prevent the inner cup 6 from pressing the drive shaft 31 to affect the drive of the drive shaft 31 and the inner crushing device 5. The minimum distance between the external crushing device 3 and the inner wall of the supporting ring 19 is D, and D is more than or equal to 1mm and less than or equal to 3mm, and preferably D=2 mm. The minimum distance between the external crushing device 3 and the inner wall of the support ring 19 is too small, so that the external crushing device 3 easily hits the inner wall of the support ring 19 during operation. And the minimum distance between the external crushing device 3 and the inner wall of the supporting ring 19 is too large, the working range of the external crushing device 3 is smaller, and the crushing effect is poorer. The lower end of the support ring 19 is integrally connected with a connecting portion 20 and a flange portion 21 in this order from top to bottom. Wherein the outer diameters of the flange portion 21 and the support ring 19 are equal, and the outer diameter of the connecting portion 20 is smaller 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 groove 23 for the flange portion 21 to catch in. The groove wall of one side of the clamping groove 23 is abutted against the connecting part 20, and the groove wall of the other side is protruded from the flange part 21. The bottom cushion 22 is fixed to the support ring 19 by engagement of the locking groove 23 with the flange portion 21 and the connecting portion 20. The arrangement of the bottom cushion pad 22 prevents the supporting ring 19 from directly contacting the stand 1 to collide, and reduces the abrasion and vibration of the supporting ring 19 and the stand 1.

Referring to fig. 5, 6 and 8, the inner cup cover 13 is provided with an annular counter 24, and the inner cup cover 13 is provided with a handle 25 at the center of the annular counter 24. The inner cup cover 13 can be axially fixed with the inner cup body 9 by adopting a locking structure, and the handle 25 is arranged so that people can apply force to the inner cup cover 13, thereby taking the inner cup piece 6 out of the outer cup piece 4. The length of the handle 25 can be prolonged through the arrangement of the annular sinking platform 24, so that people can grasp the handle 25 conveniently, and meanwhile, an anti-overflow electrode arranged on the outer cup cover 26 can be avoided, and in addition, a sealing structure for sealing the inner cup body 9 and the inner cup cover 13 can be arranged at the annular sinking platform 24. The outer cup 4 is fixedly connected with an outer cup cover 26 for sealing the outer cup 4. The minimum distance between cup cover 26 and handle 25 is d, 0.ltoreq.d.ltoreq.3 mm, preferably d=2mm. When the inner cup 6 moves upwards by a distance d, the handle 25 contacts the outer cup cover 26, so that the limit of the axial position of the inner cup 6 is realized. The outer cup cover 26 is provided with an upper cover cushion 27 located at a minimum distance from the outer cup cover 26 and the handle 25. The arrangement of the upper cover buffer cushion 27 prevents the handle 25 from colliding with the outer cup cover 26 when the handle 25 is contacted with the outer cup cover 26, and reduces abrasion and vibration of the handle 25 and the outer cup cover 26. The outer cup cover 26 is provided with a seal 28 that seals the junction of the outer cup cover 26 and the outer cup 4. One end of the sealing member 28 protrudes from the joint of the outer cup cover 26 and the outer cup member 4 and is positioned above the inner cup cover 13, and one end of the sealing member protrudes from the joint of the outer cup cover 26 and the outer cup member 4 and is clamped between the inner cup cover 13 and the outer cup member 4. The seal 28 is located above the inner cup 6 so that when the inner cup 6 moves upwardly, the inner cup 6 will contact the seal 28 and be restrained by the seal 28. One end of the sealing element 28 is inserted between the inner cup cover 13 and the outer cup 4, plays a role in limiting the radial direction of the inner cup cover 13, prevents the inner cup cover 13 from colliding with the outer cup 4, and reduces abrasion and vibration of the inner cup cover 13 and the outer cup 4. An annular groove 29 is arranged on the outer side of the circumference of the inner cup cover 13, and a lower cover buffer pad 30 is arranged in the annular groove 29. The lower cover buffer pad 30 is positioned between the inner cup cover 13 and the outer cup 4, so that collision between the inner cup cover 13 and the outer cup 4 is avoided, and abrasion and vibration of the inner cup cover 13 and the outer cup 4 are reduced. When the sealing member 28 is deformed with the increase of the use time, one end of the sealing member 28 is difficult to be inserted between the inner cup cover 13 and the outer cup 4, and the lower cover buffer pad 30 can replace the sealing member 28 to play a role of buffering.

Referring to fig. 9 and 10, the external crushing device 3 includes a driving shaft 31 and a lower blade 32 sleeved on the driving shaft 31. The driving shaft 31 may be directly connected to the motor and rotated by the motor, or may be connected to an output shaft of the motor to transmit the motion of the output shaft. The lower blade 32 includes an upper lifting blade set 321 and a lower lifting blade set 322. The surfaces of the upper lifting cutter group 321 and the lower lifting cutter group 322 are provided with pressure relief holes 333. When the outer cup 4 pulverizes the food, the food below the lower blade 32 is ejected from the pressure release hole 333 by the 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 screwed with a nut 34, and the nut 34 and the drive shaft 31 press and fix the lower blade 32. The driving shaft 31 is connected with a lower connector 35 above the nut 34 in a threaded manner, and a pressure release hole 333 of the lifting knife set 321 is aligned with the lower connector 35. Since the pressure release hole 333 of the upper lifting blade set 321 is aligned with the lower connector 35, the food sprayed from the pressure release hole 333 of the upper lifting blade set 321 impacts the lower connector 35, thereby enhancing the turbulence effect. The lower connector 35 is provided with a fixing groove 36 screwed with the driving shaft 31 and a receiving groove 37 surrounding the nut 34, and the fixing groove 36 communicates with the receiving groove 37. The lower connector 35 is provided with a guide groove 38 communicating with the accommodation groove 37, but the width of the guide groove 38 is larger than the width of the accommodation groove 37. The connection of the guide groove 38 and the receiving groove 37 is provided with a receiving 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 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 pulverizing device 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 the upper connector 42. The upper connector 42 is provided with a linkage groove 43 towards one end of the lower connector 35, and the lower connector 35 is clamped into the linkage groove 43. The lower connector 35 is clamped into the linkage groove 43 to realize mechanical linkage of the upper connector 42 and the lower connector 35, so that the inner crushing device 5 and the outer crushing device 3 are mechanically linked. If the lower connector 35 is provided with the linkage groove 43, and the upper connector 42 is clamped into the linkage groove 43, the notch of the linkage groove 43 faces upwards, and at this time, the food material easily falls into the gap between the linkage groove 43 and the upper connector 42. The linkage groove 43 is arranged on the upper connector 42, so that the food material is not 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 that guides 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 linkage groove 43 includes a positioning groove 45 distant from the notch of the linkage groove 43 and a guide groove 46 close to the notch of the linkage 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 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 1:3 to 2:3, preferably 1:2. When the lower connector 35 abuts against the guide inclined surface 47, the lower connector 35 is aligned with the positioning groove 45 and finally enters the positioning groove 45 under the guidance of the guide inclined surface 47 as the inner cup 6 slowly enters the inside of the outer cup 4. If the ratio of the height of the guide inclined surface 47 to the depth of the linkage groove 43 is too high, the depth of the positioning groove 45 is low, which is not beneficial to the circumferential linkage of the lower connector 35 and the upper connector 42; too low, the guiding effect of the guiding inclined surface 47 is poor, which is disadvantageous in that the upper connector 42 or the lower connector 35 is caught in the positioning groove 45.

It can be appreciated that the upper end of the cup holder 10 extends to the rib 11, and the cup holder 10 is provided with a clamping block clamped into the recess 12.

It will be appreciated that inner cup lid 13 is eliminated and the minimum distance between outer cup lid 26 and inner cup 6 is 0, thereby allowing outer cup lid 26 to both limit axial movement of inner cup 6 and also to seal inner cup 6.

The outer cup 4 is given its self-cleaning function and the inner cup 6 is given its grinding function. When the inner cup 6 is not needed, the inner cup 6 is removed from the outer cup 4. When the inner cup 6 is needed, the inner cup 6 is put into the outer cup 4, and the inner crushing device 5 is driven to rotate by the driving shaft 31. Finally, the self-cleaning function is realized, and the grinding function is realized.

The present embodiment is merely illustrative of the present invention and is not intended to be limiting, and modifications thereof without creative contribution can be made by those skilled in the art after reading the present specification, as long as they are protected by patent laws within the scope of claims of the present invention.
