Description

Technical Field

[0001] This utility model relates to the technical field of food processing, and in particular to a reducer for a food processing machine and a food processing machine. Background Technology

[0002] Existing food processors for grinding meat generally include a base shell, a motor and reducer installed inside the base shell, a cup body, and a blade assembly housed within the cup body. When the cup body is placed on the base shell, the output of the reducer is connected to the blade assembly via a transmission connection assembly. When the motor starts, it outputs power to the reducer, which drives the blades on the blade assembly to rotate at low speed and high torque to grind the food inside the cup. Existing food processors for grinding beans (soybeans, red beans, etc.) generally include a base shell, a motor installed inside the base shell, a cup body, and a grinding blade assembly located at the bottom of the cup body. When the cup body is placed on the base shell, the output of the motor is connected to the grinding blade assembly via a transmission connection assembly, enabling high-speed rotation of the grinding blades to grind the beans inside the cup. If a household frequently needs to grind meat and beans, they would need to purchase two different food processors, increasing the user's operating costs. Summary of the Invention

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a speed reducer for a food processing machine and a food processing machine to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a reducer for a food processing machine is designed, comprising: a housing, a planetary carrier disposed within the housing, a plurality of planetary gears rotatably coupled to the planetary carrier, a sun gear meshing with the plurality of planetary gears, and a drive shaft rotatably coupled to the housing and connected at its upper end to the sun gear. The plurality of planetary gears mesh with a ring of teeth on the housing. A plurality of slots are distributed circumferentially on the inner sidewall of the first annular portion at the top of the planetary carrier. The lower end of the drive shaft extends to the lower part of the housing and is connected to a first drive head.

[0006] Using the above technical solution, when the reducer in this technology is used in conjunction with food processing machines for meat grinding and bean grinding, only one base shell and one motor are needed. When the motor, reducer and blade assembly in the first cup are combined, meat grinding can be achieved. When the motor and the grinding blade assembly in the second cup are combined, bean grinding can be achieved. This can meet the grinding needs of different materials. Compared with the existing method of purchasing two food processing machines (requiring two base shells and two motors) to complete the grinding of meat, beans and other materials, the production cost and selling price can be greatly reduced, thereby reducing the user's operating cost.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the inner wall of the second annular portion at the lower part of the housing is provided with a first male buckle, and the outer wall at the upper end is provided with a second male buckle.

[0009] In some embodiments, the bottom of the housing is provided with a locking pin, an unlocking rocker, and a button. One end of the locking pin slides into a through hole on the housing, and the other end slides into a through hole in the second annular portion. The end of the locking pin extends into the interior of the second annular portion. A spring is sleeved on the locking pin. One end of the spring abuts against the housing, and the other end abuts against a boss on the locking pin. The button is movably installed in a mounting hole on the housing. The through hole in the middle of the unlocking rocker rotates with a column on the housing. One end of the unlocking rocker abuts against the boss, and the other end abuts against the button. Pressing the button can drive the end of the locking pin to move into the through hole in the second annular portion.

[0010] In some embodiments, the upper opening of the slot has an inverted figure-eight shape.

[0011] In some embodiments, the first male buckle and the second male buckle are each provided with three circumferences.

[0012] In some embodiments, the mounting plates at both ends of the button abut against the blocks inside the housing.

[0013] According to another aspect of this utility model, a food processing machine is designed, comprising: a base shell, a motor installed in the base shell, a first cup body, a first blade assembly installed on the first cup body, a second cup body, a second blade assembly installed on the second cup body, and any of the aforementioned reducers. A first screw-lock groove is provided on a first screw-lock seat at the top of the base shell. The output shaft of the motor is fixedly connected to a drive seat located within the first screw-lock seat. A transmission seat at the bottom of the first cup body is connected to a first blade bar on the first blade assembly. A second transmission head at the bottom of the second cup body is connected to a second blade bar on the second blade assembly. When the reducer... The speed reducer is placed on top of the base shell. The first transmission head on the speed reducer is connected to the drive slot on the drive seat. Rotating the speed reducer can engage the first male buckle on it with the first buckle slot. When the first cup is placed on top of the base shell, the insertion block on the transmission seat is connected to the slot on the speed reducer. Rotating the first cup can engage the second buckle slot on it with the second male buckle on the speed reducer. When the second cup is placed on top of the base shell, the second transmission head at the bottom of the second cup is connected to the drive slot on the drive seat. Rotating the second cup can engage the third male buckle on it with the first buckle slot.

[0014] The food processing machine of this technical solution can pulverize meat and other materials when the motor, reducer and blade assembly in the first cup are used together. When the motor and the pulverizing blade assembly in the second cup are used together, it can pulverize beans. This can meet the pulverizing needs of different materials. Compared with the existing method of purchasing two food processing machines (requiring two base shells and two motors) to complete the pulverizing of meat, beans and other materials, it can greatly reduce production costs and selling prices, thereby reducing the user's operating costs.

[0015] In some embodiments, the first rotary seat is provided with a pin groove, and each first rotary groove has an insertion port on its right side that communicates with it. An inclined surface is provided on the left side of the insertion port. When the reducer is placed on the top of the base shell, the first male rotary buckle on the reducer moves through the insertion port to the right side of the first rotary groove. At this time, the end of the locking pin on the reducer is located on the right side of the inclined surface. When the reducer is rotated counterclockwise, the end of the locking pin abuts against the inclined surface and moves. When the first male rotary buckle is engaged with the first rotary groove, the end of the locking pin is inserted into the pin groove to stop the reducer from rotating relative to the base shell.

[0016] In some embodiments, the first cup body includes a cup body and a lid covering the top of the cup body. A connecting rod is provided inside the handle of the cup body, and a compression spring is provided at the lower end of the connecting rod to abut against it. A micro switch is provided inside the base shell. The micro switch and a motor are electrically connected to a control circuit board. When the first cup body rotates and engages with the top of the base shell, the lower end of the connecting rod corresponds vertically to the trigger rod on the micro switch. When the lid is placed on top of the cup body, the lid presses against the upper end of the connecting rod, driving it downwards and pressing the trigger rod downwards, thus triggering the micro switch. After the micro switch is triggered, it sends a feedback signal to the control circuit board, after which the motor can be started. This prevents the crushing operation from starting without a lid on the cup body, which could lead to a safety accident, thereby improving safety. Attached Figure Description

[0040] The output shaft of the motor 3 is fixedly connected to a drive seat 31 located in the first rotary seat 21, and a drive groove is provided in the drive seat 31.

[0041] The first blade assembly 5 includes a first blade holder 51 and a plurality of blades 52 distributed on the first blade holder 51. The first blade holder 51 is rotatably engaged with the first cup body 4. The bottom of the first cup body 4 is provided with a transmission seat 41, which is fixedly connected to the first blade holder 51. A plurality of insertion blocks 411 are distributed circumferentially on the outer side wall of the transmission seat 41. Two, three or more second screw grooves 42 are distributed circumferentially on the lower end of the first cup body 4. The number of second screw grooves 42 is the same as the number of second male screws 114 on the reducer 1. A plurality of L-shaped fasteners 43 are distributed circumferentially on the bottom of the first cup body 4. The interior of the L-shaped fasteners 43 forms the second screw grooves 42.

[0042] The second blade assembly 7 includes a second blade holder and multiple crushing blades fixed to the upper part of the first blade holder. The second blade holder is rotatably engaged with the second cup body 6. The bottom of the second cup body 6 is provided with a second transmission head, which is fixedly connected to the second blade holder. The structure of the second transmission head is the same as that of the first transmission head 18. Two, three, or more third male screw threads are distributed around the lower end of the inner circumference of the second cup body 6. The number and structure of the third male screw threads are the same as those of the first male screw threads 113 on the reducer 1.

[0043] The first cup body 4 includes a cup body 4a and a cup lid 4b covering the top of the cup body 4a. The handle of the cup body 4a is provided with a connecting rod 44. The lower end of the connecting rod 44 is provided with a compression spring 45 that abuts against it. The lower end of the compression spring 45 abuts against the handle. The base shell 2 is provided with a micro switch 8. The micro switch 8 and the motor 3 are electrically connected to the control circuit board respectively.

[0044] The second cup body 6 includes a cup cylinder 6a, a lid 6b covering the top of the cup cylinder 6a, and a cup base 6c that is sealed and fixed to the bottom of the cup cylinder 6a. The second cutter bar is rotatably engaged with the cup base 6c.

[0045] When the reducer 1 is placed on top of the base housing 2, the first transmission head 18 at the bottom of the reducer 1 is connected to the drive slot on the drive seat 31. The first male swivel 113 on the reducer 1 moves through the insertion port 212 to the right side of the first swivel slot 211. At this time, the end 191a of the locking pin shaft 191 on the reducer 1 is located on the right side of the inclined surface 213, that is, in the insertion hole 212. Rotating the reducer 1 clockwise, the first male swivel 113 moves into the first swivel slot 211, and the end 191a of the locking pin shaft 191 and the inclined surface 213 are connected. 3. The locking pin 191 is abutted and moved axially. When the first male swivel 113 is engaged with the first swivel groove 211, the end of the locking pin 191 is inserted into a pin groove 214, which stops the reducer 1 from rotating relative to the base shell 2, thus realizing the connection between the reducer 1 and the base shell 2. When the button 193 of the reducer 1 is pressed, the locking pin 191 can be driven to move, so that the end 191a of the locking pin 191 leaves the pin groove 214. Then, the reducer 1 can be removed by rotating it counterclockwise.

[0046] After the reducer 1 is connected to the top of the base shell 2, when the first cup body 4 is placed on the top of the base shell 2, the transmission seat 41 is inserted into the first annular part 121, and the insertion block 411 is connected to the slot 1211 on the reducer 1. Rotating the first cup body 4 can make its second screw groove 42 engage with the second male screw 114 of the reducer 1. After engaging, the lower end 441 of the connecting rod 44 corresponds vertically to the trigger rod 81 on the micro switch 8. When the cup lid 4b is placed on the top of the cup body 4a, the lower part of the cup lid 4b presses against the upper end of the connecting rod 44, driving the connecting rod 44 to move down. The lower end 441 of the connecting rod 44 presses against the trigger rod 81 on the micro switch 8, causing the micro switch 8 to move down, which can trigger the micro switch 8. When the cup lid 4b is removed, the connecting rod 44 is driven to move up under the action of the compression spring 45, and the trigger rod 81 on the micro switch 8 moves up to reset, and the micro switch 8 is not triggered. When the first cup body 4 is rotated in the opposite direction, the second screw groove 42 can disengage from the second male screw 114. When the second screw groove 42 and the second male screw 114 are engaged, the motor 3 starts and drives the drive seat 31 to rotate. The drive seat 31 drives the first transmission head 18 on the reducer 1 to rotate, which in turn drives the first annular part 121 at the top of the reducer 1 to rotate, realizing the high-speed to low-speed rotation. The rotation of the first annular part 121 drives the transmission seat 41 to rotate, which in turn drives the first blade bar 51 to rotate. The rotation of the first blade bar 51 drives the multiple blades 52 on it to rotate, which can realize the crushing of meat and other materials placed in the first cup body 4.

[0047] When the reducer 1 and the first cup 4 are not placed on top of the base shell 2, the second cup 6 can be placed on top of the base shell 2. When the second cup 6 is placed on top of the base shell 2, the second transmission head at the bottom of the second cup 6 is connected to the drive groove on the drive seat 31. The third male buckle on the bottom of the second cup 6 moves through the inlet 212 to the right side of the first buckle groove 211. Rotating the second cup 6 clockwise will cause the third male buckle on it to engage with the first buckle groove 211. Rotating the second cup 6 in the opposite direction will cause the third buckle groove to disengage from the first buckle groove 211. When the third buckle groove and the first buckle groove 211 are engaged, the motor 3 starts and drives the drive seat 31 to rotate. The rotation of the drive seat 31 drives the second transmission head to rotate and drives the second blade to rotate. The rotation of the second blade drives the multiple crushing blades on it to rotate, thereby crushing beans and other materials placed in the second cup 6.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
