Description

Technical Field

[0001] The invention relates to food processing technology, in particular to a food processing machine which is easy to operate. Background Art

[0002] People like to grind grains and seasonings into powder before eating. However, the self-cleaning wall-breaking machine, which is popular in the market, often has a non-detachable mixing cup to meet the self-cleaning function, which makes it difficult for people to replace the mixing cup with a dry grinding cup, making it impossible to grind grains and seasonings, which needs to be improved. Summary of the invention

[0003] The object of the present invention is to provide a food processor which is easy to operate and can realize a grinding function while realizing a self-cleaning function.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A food processor which is easy to operate comprises a machine base and a mixing cup installed on the machine base, wherein the mixing cup comprises an outer cup member with an outer crushing device and an inner cup member with an inner crushing device installed inside the outer cup member, the outer cup member is integrally connected to the machine base, the inner cup member is detachably connected to the outer cup member, and the outer crushing device comprises a lower blade and a driving shaft for driving the lower blade and the inner crushing device to rotate.

[0006] By adopting the above technical solution, the outer cup is endowed with a self-cleaning function, and the inner cup is endowed with a grinding function. When the inner cup is not needed, the inner cup can be removed from the outer cup. When the inner cup is needed, the inner cup is installed in the outer cup, and the inner crushing device is driven to rotate by the driving shaft. Finally, the self-cleaning function is realized while the grinding function is realized.

[0007] The present invention is further configured as follows: the internal crushing device is connected to an upper connecting head, the driving shaft is connected to a lower connecting head, and one of the upper connecting head and the lower connecting head is provided with a linkage groove, and the other is inserted into the linkage groove and tightly abuts against the wall of the linkage groove to achieve circumferential fixation of the upper connecting head and the lower connecting head.

[0008] By adopting the above technical solution, the mechanical linkage between the upper connector and the lower connector is achieved by utilizing the clamping of the linkage groove, thereby achieving the mechanical linkage between the inner crushing device and the outer crushing device.

[0009] The present invention is further configured as follows: the linkage groove includes a positioning groove away from the linkage groove opening and a guide groove close to the linkage groove opening, the groove wall of the guide groove is provided with multiple guide slopes, the multiple guide slopes are in the same direction, and the cross-section of the positioning groove is non-circular.

[0010] By adopting the above technical solution, when the inner cup is installed inside the outer cup, the linkage groove needs to be aligned with the upper connector or the lower connector so that the upper connector or the lower connector can be inserted into the linkage groove. However, the linkage groove is located below the inner cup, and it is difficult for people to directly observe the alignment of the linkage groove with the upper connector or the lower connector. When the upper connector or the lower connector abuts the guide slope, as the inner cup slowly enters the outer cup, under the guidance of the guide slope, the upper connector or the lower connector is aligned with the positioning groove and finally enters the positioning groove.

[0011] The present invention is further configured such that the ratio of the height of the guide slope to the depth of the linkage groove is 1:3-2:3.

[0012] By adopting the above technical solution, if the height of the guide bevel accounts for too high a proportion of the depth of the linkage groove, the depth of the positioning groove is relatively low, which is not conducive to the circumferential linkage of the lower connector and the upper connector; if it is too low, the guiding effect of the guide bevel is relatively poor, which is not conducive to the upper connector or the lower connector being inserted into the positioning groove.

[0013] The present invention is further configured such that: the cross section of the positioning groove is a polygon.

[0014] By adopting the above technical solution, the outer part of the upper connector or the lower connector is in a polygonal column shape, so that the positioning groove and the upper connector or the lower connector are easy to process, thereby reducing production costs.

[0015] The present invention is further configured as follows: the lower blade is sleeved with the drive shaft, the drive shaft is threadedly connected with a nut for fixing the lower blade, and the lower connector is threadedly connected with the drive shaft and is located above the nut.

[0016] The present invention is further configured as follows: the lower connecting head is provided with a fixing groove threadedly connected to the driving shaft and a receiving groove wrapping the nut, and the fixing groove and the receiving groove are communicated.

[0017] By adopting the above technical solution, the nut is wrapped with the lower connecting head, which reduces the contamination of the driving shaft threaded with the nut by food, making it difficult for the nut to withdraw from the driving shaft.

[0018] The present invention is further configured as follows: the lower connector is provided with a guide groove connected to the accommodating groove, the width of the guide groove is greater than the width of the accommodating groove, and an accommodating chamfer is provided at the connection between the guide groove and the accommodating groove.

[0019] By adopting the above technical solution, the setting of the guide groove and the receiving chamfer makes it easier for the nut to enter the receiving groove.

[0020] The present invention is further configured as follows: the lower blade comprises an upper rising blade group and a lower rising blade group, surfaces of the upper rising blade group and the lower rising blade group are both provided with pressure relief holes, and the pressure relief hole of the upper rising blade group is aligned with the lower connecting head.

[0021] By adopting the above technical solution, when the outer cup is crushing food, the food below the lower blade is ejected from the pressure relief hole due to the greater pressure generated by the lower blade. Since the pressure relief hole of the upper blade assembly is aligned with the lower connector, the food ejected from the pressure relief hole of the upper blade assembly impacts the lower connector, thereby enhancing the turbulence effect.

[0022] The present invention is further configured as follows: the upper connector is provided with a linkage groove, and the lower connector is snapped into the linkage groove.

[0023] By adopting the above technical solution, if the lower connector is provided with a linkage groove, and the upper connector is inserted into the linkage groove, the linkage groove is facing upward, and at this time, the food is easy to fall into the gap between the linkage groove and the upper connector. If the linkage groove is provided on the upper connector, the food is easy to fall into the linkage groove under the action of its own gravity.

[0024] In summary, the present invention has the following beneficial effects:

[0025] The outer cup is endowed with a self-cleaning function, and the inner cup is endowed with a grinding function. When the inner cup is not needed, the inner cup can be removed from the outer cup. When the inner cup is needed, the inner cup is installed in the outer cup, and the inner crushing device is driven to rotate by the driving shaft. Finally, the self-cleaning function is realized while the grinding function is realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figure 1 A food processor with easy operation includes a machine base 1 and a mixing cup 2 mounted on the machine base 1. The mixing cup 2 includes an outer cup member 4 with an outer crushing device 3 and an inner cup member 6 with an inner crushing device 5 and mounted inside the outer cup member 4. The outer cup member 4 and the machine base 1 are connected as one piece.

[0040] Reference Figure 2 The inner side of the cup body of the outer cup 4 is provided with a plurality of protrusions 7 along the circumference of the outer cup 4, and the plurality of protrusions 7 extend axially along the outer cup 4. The protrusions 7 can play a role of disturbing the flow in the outer cup 4, and enhance the crushing effect of the outer crushing device 3. The lower ends of the plurality of protrusions 7 are flush, while the upper ends are of different heights, so that when the food is crushed in the outer cup 4, the plurality of protrusions 7 can reduce the resistance to the flow of the food while achieving the disturbing effect, and reduce the load of the motor.

[0041] reference Figure 3 , 45, each convex block 7 includes a facing block 71 and a back block 72, but the arc length of the facing block 71 is smaller than the arc length of the back block 72, and the rotation direction of the drive shaft 31 is from the facing block 71 to the back block 72. If the arc length of the facing block 71 is greater than the arc length of the back block 72, the inner connection between the back block 72 and the cup body of the outer cup member 4 is difficult to be impacted, which causes the food to pile up easily. If the arc length of the facing block 71 is less than the arc length of the back block 72, the food will impact the facing block 71 and the back block 72 at the same time, which is not easy to cause the food to pile up. The inner cup member 6 includes a base 8, an inner cup body 9, and a cup body holder 10 located between the base 8 and the inner cup body 9. The base 8 and the inner cup body 9 are fixedly connected by screws, and the cup body holder 10 is squeezed by the base 8 and the inner cup body 9 to achieve a fixed connection with the base 8 and the inner cup body 9. The inner cup body 9 is provided with a plurality of ribs 11 protruding toward the inside of the inner cup body 9 along the circumferential direction, thereby forming a depression 12 on the outer surface of the inner cup body 9. The inner cup member 6 also includes an inner cup cover 13 that seals the inner cup body 9. The setting of the inner cup cover 13 serves to separate the inside of the inner cup member 6 from the inside of the outer cup member 4, thereby preventing the powder generated by grinding in the inner cup member 6 from entering the inside of the outer cup member 4 from the inside of the inner cup member 6, and reducing the pollution to the inside of the outer cup member 4. The inner cup cover 13 protrudes radially from the inner cup body 9, and the distance between the inner cup cover 13 and the outer cup member 4 is X, 0<X≤1mm, preferably X=0.5mm. The inner cup cover 13 protrudes radially from the inner cup body 9 and the distance between it and the cup body of the outer cup member 4 is small, so that the radial limitation of the inner cup member 6 can be achieved by relying on 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 body holder 10 are provided with a plurality of grooves 14 along the axial direction of the inner cup member 6 and penetrating the base 8 and the cup body holder 10. The grooves 14 correspond to the protrusions 7 one by one so that the protrusions 7 can be inserted into the corresponding grooves 14, and the plurality of grooves 14 are aligned with the lower ends of the corresponding protrusions 7. The protrusions 7 are inserted into the grooves 14 along the axial direction, thereby realizing the circumferential fixation of the outer cup member 4 and the inner cup member 6. The lower end of the protrusion 7 is close to the outer crushing device 3, and the groove 14 corresponds to the lower end of the protrusion 7, so the matching parts of the plurality of grooves 14 and the plurality of protrusions 7 can be close to the outer crushing device 3, thereby enhancing the circumferential fixation effect of the inner cup member 6 and the outer cup member 4. When the drive shaft 31 rotates, the inner cup member 6 has a tendency to rotate along the drive shaft 31. Since the arc length of the face block 71 is smaller than the arc length of the back block 72, the width of the fitting surface between the face block 71 and the groove 14 is smaller than the width of the fitting surface between the back block 72 and the groove 14, and the guiding effect of the face block 71 is smaller than the guiding effect of the back block 72. Therefore, it is more difficult for the groove 14 to pass over the connection between the face block 71 and the back block 72 along the rotation direction of the drive shaft 31 than against the rotation direction of the drive shaft 31, thereby enhancing the circumferential fixing effect of the outer cup member 4 and the inner cup member 6. The cup body holder 10 is provided with mounting grooves 15 connected to the groove 14 on both side walls opposite to the groove 14, and the cup body holder 10 is provided with a circumferential buffer pad 16 whose two ends are respectively inserted into the two mounting grooves 15 and tightly attached to the protrusion 7.When the projection 7 is inserted into the groove 14, the projection 7 abuts against the circumferential buffer pad 16. During grinding, when the outer crushing device 3 drives the inner crushing device 5 to rotate, the outer cup member 4 and the inner cup member 6 tend to rotate relative to each other. The circumferential buffer pad 16 prevents the projection 7 from colliding with the groove wall of the groove 14, and reduces the wear and vibration of the outer cup member 4 and the inner cup member 6. The cup body holder 10 is provided with a limiting rod 17 in the groove 14, which is integrally connected to the cup body holder 10, and the circumferential buffer pad 16 is provided with a limiting groove 18 for the limiting rod 17 to be inserted. The limiting rod 17 is inserted into the limiting groove 18 to enhance the installation strength of the circumferential buffer pad 16 and the groove 14.

[0042] Reference Figure 6 and 7 , the edge of the base 8 is provided with a support ring 19 extending downward, and the external crushing device 3 is located inside the support ring 19. The support ring 19 plays the role of supporting the inner cup 6 to prevent the inner cup 6 from exerting pressure on the drive shaft 31 and affecting the transmission 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 support ring 19 is D, 1mm≤D≤3mm, preferably D=2mm. If the minimum distance between the external crushing device 3 and the inner wall of the support ring 19 is too small, the external crushing device 3 is easy to hit the inner wall of the support ring 19 during operation. If the minimum distance between the external crushing device 3 and the inner wall of the support ring 19 is too large, the working range of the external crushing device 3 is small and the crushing effect is poor. The lower end of the support ring 19 is integrally connected with a connecting portion 20 and a flange portion 21 from top to bottom. Among them, 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 that of the flange portion 21. The bottom buffer pad 22 is provided at the lower end of the support ring 19, and the bottom buffer pad 22 is provided with a slot 23 for the flange 21 to be inserted. The slot wall on one side of the slot 23 abuts against the connecting portion 20, and the slot wall on the other side protrudes from the flange 21. The bottom buffer pad 22 is fixed to the support ring 19 by the cooperation of the slot 23, the flange 21 and the connecting portion 20. The provision of the bottom buffer pad 22 prevents the support ring 19 from directly contacting the base 1 and colliding with it, thereby reducing the wear and vibration of the support ring 19 and the base 1.

[0043] Reference Figure 5 , 68, the inner cup cover 13 is provided with an annular sink 24, and the inner cup cover 13 is provided with a handle 25 at the center of the annular sink 24. The inner cup cover 13 can be axially fixed with the inner cup body 9 by a locking structure, and the setting of the handle 25 is convenient for people to apply force to the inner cup cover 13, so as to remove the inner cup 6 from the outer cup 4. The setting of the annular sink 24 can extend the length of the handle 25, so that people can grasp the handle 25 firmly, and at the same time, it can also avoid the anti-overflow electrode provided on the outer cup cover 26. In addition, a sealing structure for sealing the inner cup body 9 and the inner cup cover 13 can be installed at the annular sink 24. The outer cup 4 is fixedly connected with an outer cup cover 26 for sealing the outer cup 4. The minimum distance between the outer cup cover 26 and the handle 25 is d, 0≤d≤3mm, preferably d=2mm. When the inner cup 6 moves upward by a distance d, the handle 25 will contact the outer cup cover 26, thereby realizing the limit of the axial position of the inner cup 6. The outer cup cover 26 is provided with an upper cover cushion 27 located at the minimum distance between the outer cup cover 26 and the handle 25. The setting of the upper cover cushion 27 serves to prevent the handle 25 and the outer cup cover 26 from colliding when the handle 25 and the outer cup cover 26 are in contact, and to reduce the wear 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 connection between the outer cup cover 26 and the outer cup member 4. One end of the seal 28 protrudes from the connection between the outer cup cover 26 and the outer cup member 4 and is located above the inner cup cover 13, and one end protrudes from the connection between the outer cup cover 26 and the outer cup member 4 and is stuck between the inner cup cover 13 and the outer cup member 4. The seal 28 is located above the inner cup member 6, so when the inner cup member 6 moves upward, the inner cup member 6 will contact the seal 28 and be limited by the seal 28. One end of the seal 28 is inserted between the inner cup cover 13 and the outer cup member 4, which plays a role in radially limiting the inner cup cover 13, avoiding collision between the inner cup cover 13 and the outer cup member 4, and reducing wear and vibration of the inner cup cover 13 and the outer cup member 4. An annular groove 29 is provided on the circumferential outer side of the inner cup cover 13, and a lower cover buffer pad 30 is provided in the annular groove 29. The lower cover buffer pad 30 is located between the inner cup cover 13 and the outer cup member 4, avoiding collision between the inner cup cover 13 and the outer cup member 4, and reducing wear and vibration of the inner cup cover 13 and the outer cup member 4. When the seal 28 is deformed as the use time increases, one end of the seal 28 is difficult to insert between the inner cup cover 13 and the outer cup member 4. At this time, the lower cover buffer pad 30 can replace the seal 28 to play a buffering role.

[0044] Reference Fig. 9 and 10The outer crushing device 3 includes a driving shaft 31 and a lower blade 32 sleeved on the driving shaft 31. The driving shaft 31 can be directly connected to the motor and driven to rotate by the motor, or it can be connected to the output shaft of the motor to transmit the movement of the output shaft. The lower blade 32 includes an upper blade group 321 and a lower blade group 322. Pressure relief holes 333 are provided on the surfaces of the upper blade group 321 and the lower blade group 322. When the outer cup 4 crushes the food, the food below the lower blade 32 is ejected from the pressure relief hole 333 due to the greater pressure generated by the lower blade 32. The driving shaft 31 is provided with a step 33, and the lower blade 32 abuts against the step 33 of the driving shaft 31, and the driving shaft 31 is threadedly connected with a nut 34, and the nut 34 and the driving shaft 31 squeeze and fix the lower blade 32. The driving shaft 31 is threadedly connected with a lower connector 35 located above the nut 34, and the pressure relief hole 333 of the upper blade group 321 is aligned with the lower connector 35. Since the pressure relief hole 333 of the upper blade assembly 321 is aligned with the lower connector 35, the food ejected from the pressure relief hole 333 of the upper blade assembly 321 impacts the lower connector 35, thereby enhancing the turbulence effect. The lower connector 35 is provided with a fixing groove 36 threadedly connected to the drive shaft 31 and a receiving groove 37 wrapping the nut 34, and the fixing groove 36 and the receiving groove 37 are connected. The lower connector 35 is provided with a guide groove 38 connected to the receiving groove 37, but the width of the guide groove 38 is greater than the width of the receiving groove 37. A receiving chamfer 39 is provided at the connection between the guide groove 38 and the receiving groove 37. By wrapping the nut 34 with the lower connector 35, the drive shaft 31 threadedly connected to the nut 34 is reduced from being contaminated by food, which makes it difficult for the nut 34 to withdraw from the drive shaft 31. 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.

[0045] Reference Fig. 9 and 10 The internal crushing device 5 includes an upper blade 40 and an upper connecting shaft 41. One end of the upper connecting shaft 41 is connected to the upper blade 40, and the other end is fixedly connected to an upper connecting head 42. A linkage groove 43 is provided at one end of the upper connecting head 42 facing the lower connecting head 35, and the lower connecting head 35 is inserted into the linkage groove 43. The mechanical linkage between the upper connecting head 42 and the lower connecting head 35 is achieved by inserting the lower connecting head 35 into the linkage groove 43, thereby realizing the mechanical linkage between the internal crushing device 5 and the external crushing device 3. If the lower connecting head 35 is provided with a linkage groove 43, and the upper connecting head 42 is inserted into the linkage groove 43, the notch of the linkage groove 43 faces upward. At this time, the food is easy to fall into the gap between the linkage groove 43 and the upper connecting head 42. If the linkage groove 43 is set on the upper connecting head 42, the food is not easy to fall into the linkage groove 43 under the action of its own gravity. Refer to Fig.11, the notch of the linkage groove 43 is provided with a linkage chamfer 44 for guiding the lower connector 35 to be inserted into the linkage groove 43, so that the lower connector 35 can be more easily inserted into the linkage groove 43. The linkage groove 43 includes a positioning groove 45 away 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 multiple guide slopes 47 are in the same direction. The cross-section of the positioning groove 45 is polygonal, preferably square, and the outer part of the lower connector 35 is rectangular. The ratio of the height of the guide slope 47 to the depth of the linkage groove 43 is 1:3-2:3, preferably 1:2. When the lower connector 35 abuts the guide slope 47, as the inner cup member 6 slowly enters the interior of the outer cup member 4, under the guidance of the guide slope 47, the lower connector 35 is aligned with the positioning groove 45 and finally enters the positioning groove 45. If the height of the guide slope 47 accounts for too high a proportion of the depth of the linkage groove 43, the depth of the positioning groove 45 is relatively low, which is not conducive to the circumferential linkage between the lower connector 35 and the upper connector 42; if it is too low, the guiding effect of the guide slope 47 is relatively poor, which is not conducive to the upper connector 42 or the lower connector 35 being inserted into the positioning groove 45.

[0046] It can be understood that the upper end of the cup body holder 10 extends to the rib 11 , and the cup body holder 10 is provided with a block that is inserted into the recess 12 .

[0047] It can be understood that the inner cup cover 13 is removed, and the minimum distance between the outer cup cover 26 and the inner cup member 6 is 0, so that the outer cup cover 26 can not only limit the axial movement of the inner cup member 6, but also play a role in sealing the inner cup member 6.

[0048] The outer cup 4 is endowed with a self-cleaning function, and the inner cup 6 is endowed with a grinding function. When the inner cup 6 is not needed, the inner cup 6 can be removed from the outer cup 4. When the inner cup 6 is needed, the inner cup 6 is installed in 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 while the grinding function is realized.

[0049] This embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
