Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a main unit and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of a food processor mainly include, but are not limited to, making soy milk, juicing, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or meat grinders—machines that pulverize and mix food. Current food processors only have the function of pulverizing ingredients; after chopping the ingredients, they cannot further blend them evenly. Summary of the Invention

[0003] The purpose of this application is to provide a main unit and a food processor that can both crush and blend food ingredients.

[0004] This application provides a host computer. The host computer includes: a housing; a motor disposed within the housing, the motor including a motor shaft; and a forward / reverse speed control device disposed within the housing, the forward / reverse speed control device including an input frame, a shifting component, a high-speed drive component, a low-speed drive component, and a gear assembly. The motor shaft drives the input frame to rotate forward or reverse. The shifting component is movable between a first position and a second position via a lifting mechanism, and engages with the input frame in these two positions respectively. The gear assembly includes a ring gear, an output frame, a first sun gear, and a planetary gear disposed on the output frame. The high-speed drive component engages with the output frame. The first sun gear is fixed to the bottom end of the low-speed drive component, and the first planetary gear meshes with the first sun gear and the gear ring. When the input frame rotates forward, the lifting mechanism moves the shifting component to a first position to engage with the high-speed drive component, which in turn drives the output frame to rotate. When the input frame rotates in reverse, the lifting mechanism moves the shifting component to a second position to engage with the low-speed drive component, which in turn drives the first sun gear to rotate, causing the output frame to rotate along with the first planetary gear. When the input frame rotates forward, the output frame drives the rotating tool assembly to rotate at high speed, which can then pulverize the ingredients. When the input frame rotates in reverse, the output frame drives the rotating tool assembly to rotate at a lower speed, which can then stir the pulverized ingredients and perform other functions such as kneading dough, thus better meeting the user's needs. Furthermore, when the motor rotates forward or in reverse, the forward and reverse speed switching device can automatically switch between high and low speeds under the action of centrifugal force, thereby achieving different output speeds for forward and reverse rotation of the motor. This application does not require control circuits or control chips to achieve high-speed and low-speed switching, thus eliminating the need for circuit redesign, making implementation easier, and resulting in lower overall costs. The rotating tool assembly can be a stirring blade assembly capable of cutting food into smaller pieces. Alternatively, the rotating tool assembly can also include interchangeable tools, such as stirring tools, mixing tools, chopping tools, pounding tools, etc.

[0005] Furthermore, the lifting mechanism includes an internal thread disposed inside the input frame and an external thread disposed outside the shifting component, the internal thread engaging with the external thread. Through the engagement of the internal and external threads, rotation of the input frame allows the shifting component to rise or fall, and the structure is simple and easy to assemble.

[0006] Furthermore, the shifting component includes a high-speed stop position disposed at one end of the external thread and a low-speed stop position disposed at the other end of the external thread. The input frame includes a high-speed stop surface corresponding to the high-speed stop position and a low-speed stop surface corresponding to the low-speed stop position. When the input frame rotates forward, the shifting component descends until the high-speed stop position and the high-speed stop surface abut together, at which point the input frame drives the shifting component to rotate forward together. When the input frame rotates in reverse, the shifting component rises until the low-speed stop position and the low-speed stop surface abut together, at which point the input frame drives the shifting component to rotate in reverse together. In this way, the shifting component completes the switching between lifting and rotating.

[0007] Furthermore, the input frame includes a high-speed stop groove and a stop block disposed within the high-speed stop groove, with the high-speed stop surface disposed on the stop block. During assembly, the shifting component is first installed into the input frame, and then the stop block is installed into the high-speed stop groove, making assembly more convenient.

[0008] Furthermore, the high-speed stop groove is tapered, wider at the top and narrower at the bottom, and the shape of the stop block matches the high-speed stop groove. The stop block is inserted into the high-speed stop groove from the outside of the input frame. In this way, the high-speed stop groove can limit the stop block in the vertical direction, preventing the stop block from detaching from the high-speed stop groove under the action of gravity.

[0009] Furthermore, the input frame includes a bearing disposed on the outside of the stop block. The bearing can limit the stop block from the outside, making the input frame structure more stable and less prone to shaking.

[0010] Furthermore, the lifting mechanism includes a spiral guide groove disposed inside the input frame and a guide post disposed outside the shifting component, the guide post being slidably engaged with the spiral guide groove. Alternatively, the lifting mechanism includes a guide post disposed inside the input frame and a spiral guide groove disposed outside the shifting component, the guide post being slidable within the spiral groove. Through the engagement of the guide post and guide groove, rotation of the input frame allows the shifting component to rise or fall, and the structure is simple and easy to assemble.

[0011] Furthermore, the low-speed drive component includes a rotating shaft and a low-speed drive block, with the first sun gear fixed to the bottom end of the rotating shaft and the low-speed drive block fixed to the top end of the rotating shaft. Thus, the rotating shaft and the low-speed drive block are manufactured separately and then assembled together, making manufacturing easy.

[0012] Furthermore, the top end of the rotating shaft is provided with a flat section, and the low-speed drive block is provided with a flat section hole that mates with the flat section. The mating of the flat section and the flat section hole makes the fit between the rotating shaft and the low-speed drive block more reliable, preventing relative rotation.

[0013] Furthermore, the low-speed drive block is provided with a low-speed drive protrusion, and the shifting component is provided with a low-speed drive groove corresponding to the low-speed drive protrusion. The shifting component and the low-speed drive block are joined together by the cooperation of the low-speed drive protrusion and the low-speed drive groove. The cooperation of the low-speed drive protrusion and the low-speed drive groove allows for a more convenient and reliable joining of the shifting component and the low-speed drive block.

[0014] Furthermore, the high-speed drive component is provided with a high-speed drive protrusion, and the shift component is provided with a high-speed drive groove corresponding to the high-speed drive protrusion. The shift component and the high-speed drive component are combined by the cooperation of the high-speed drive protrusion and the high-speed drive groove. The cooperation of the high-speed drive protrusion and the high-speed drive groove enables the shift component and the high-speed drive component to be combined more conveniently and reliably.

[0015] Furthermore, the high-speed drive component has a downwardly extending latching portion, and the output frame has a latching slot corresponding to the latching portion. The latching portion and the latching slot engage to allow the output frame to rotate together with the high-speed drive component. Thus, the high-speed drive component can rotate along with the output frame through the engagement of the latching portion and the latching slot.

[0016] Furthermore, the input frame is equipped with a second sun gear and a second planetary gear. The second sun gear is connected to the motor shaft, and the second planetary gear meshes with the second sun gear and the ring gear. The gear shaft of the second planetary gear is fixed to the input frame. By setting the second sun gear and the second planetary gear, the motor shaft can be decelerated before the speed is transmitted to the input frame.

[0017] This application also provides a food processor. The food processor includes: a food container comprising a container body and a container lid covering the container body; a main unit as described above, disposed on the container lid; and a rotating tool assembly installed within the container body, the rotating tool assembly being connected to the output rack. The rotating tool assembly may be a mixing blade assembly capable of cutting food into smaller pieces. Alternatively, the rotating tool assembly may also include interchangeable tools, such as a mixing tool, a blending tool, a chopping tool, a pounding tool, etc.

It includes a base for receiving a container body; a container lid covering the container body; a main unit as described above, disposed on the base; and a rotating tool assembly installed inside the container body, the rotating tool assembly being connected to the output rack.

[0028] Please see Figures 1 to 7 The food processor 100 includes a food container 50, a main unit 40, and a rotating tool assembly 60. In the illustrated embodiment, the rotating tool assembly is a blade assembly. The food container 50 includes a container body 51 and a container lid 52 covering the container body 51. The food container 50 can be used to hold food to be processed, such as meat. The food is pulverized within the food container 50. The blade assembly 60 is installed within the container body 51 and includes a blade shaft 61 and blades 62 disposed on the blade shaft 61.

[0029] The main unit 40 is disposed on the container lid 52. The main unit 40 includes a housing 10, a motor 20, a forward / reverse speed control device 30, a forward / reverse switch 19, a forward button 18, and a reverse button 17. The motor 20 is disposed inside the housing 10, and the motor 20 includes a motor shaft. The forward button 18 and the reverse button 17 are respectively coupled to the forward / reverse switch 19. Pressing the forward button 18 controls the motor 20 to start rotating forward, and pressing the reverse button 17 controls the motor 20 to start rotating in reverse.

[0030] The outer casing 10 includes a base 11, an upper casing 12 covering the base 11, and a cover 13 disposed on the upper casing 12. In one embodiment, during assembly, the forward / reverse speed control device 30 is first fixed to the motor 20, then the motor 20 and the forward / reverse speed control device 30 are installed as a whole inside the base 11, and then the upper casing 12 is fixed to the base 11. The forward / reverse switch 19 is disposed inside the upper casing 12, and the forward button 18 and the reverse button 17 are disposed on the cover 13.

[0031] A forward / reverse speed control device 30 is disposed within the housing 10. The device includes an input frame 31, a shifting component 32, a high-speed drive component 33, a low-speed drive component 34, and a gear assembly 35. The motor shaft drives the input frame 31 to rotate forward or reverse. The shifting component 32 is movable between a first position and a second position via a lifting mechanism 36, and engages with the input frame 31 in both positions. The gear assembly 35 includes a ring gear 354, a first sun gear 352, an output frame 351, and a first planetary gear 353 disposed on the output frame 351. The high-speed drive component 33 engages with the output frame 351. The first sun gear 352 is fixed to the bottom end of the low-speed drive component 34. The first planetary gear 353 meshes with the first sun gear 352 and the ring gear 354. The stirring blade assembly 60 is connected to the output frame 351.

[0032] When the input frame 31 rotates clockwise, the shifting component 32, under the action of centrifugal force, moves to a first position via the lifting mechanism 36 and engages with the high-speed drive component 33, which in turn drives the output frame 351 to rotate. When the input frame 31 rotates counterclockwise, the shifting component 32, also under the action of centrifugal force, moves to a second position via the lifting mechanism 36 and engages with the low-speed drive component 34, which in turn drives the first sun gear 352 to rotate, thereby causing the output frame 351 to rotate together with the first planetary gear 353. In one embodiment, "clockwise rotation" refers to clockwise rotation, and "counterclockwise rotation" refers to counterclockwise rotation. In another embodiment, "clockwise rotation" refers to counterclockwise rotation, and "counterclockwise rotation" refers to clockwise rotation.

[0033] Please see Figure 4 and Figure 5 When the input frame 31 rotates clockwise, the shifting component 32 is driven to descend along the lifting mechanism 36 under the action of centrifugal force until it reaches its first position and directly engages with the high-speed drive component 33. At this point, the shifting component 32 stops descending and rotates together with the input frame 31, and the high-speed drive component 33 rotates along with the shifting component 32. The high-speed drive component 33 drives the output frame 351 to rotate. At this time, there is no deceleration through the gear assembly 35, and the output frame 351 drives the stirring blade assembly 60 to rotate at high speed. Please refer to [link to relevant documentation]. Figure 6 and Figure 7When the input frame 31 reverses, the shifting member 32 is driven to rise along the lifting mechanism 36 under the action of centrifugal force until it reaches its first position and engages with the low-speed drive member 34. At this time, the shifting member 32 stops rising and rotates together with the input frame 31, and the low-speed drive member 34 rotates with the shifting member 32, driving the first sun gear 352 to rotate, thereby causing the output frame 351 to rotate with the first planetary gear 353. At this time, deceleration is achieved through the gear assembly 35, and the output frame 351 drives the stirring blade assembly 60 to rotate at a lower speed.

[0034] In another embodiment, when the input frame 31 rotates forward, the lifting mechanism 36 drives the shifting member 32 to rise to its first position and engage with the high-speed drive member 33, which in turn drives the output frame 351 to rotate. When the input frame 31 rotates in reverse, the shifting member 32 descends along the lifting mechanism 36 to its second position and engages with the low-speed drive member 34, which in turn drives the first sun gear 352 to rotate, thereby causing the output frame 351 to rotate together with the first planetary gear 353. For example, Figure 3 The outer casing 10 can be placed upside down in the base of the food processor, which also includes a container body received by the base and a rotating tool assembly mounted in the container body and connected to the output rack.

[0035] This food processor 100, when the input rack 31 rotates forward, drives the output rack 351 to drive the mixing blade assembly 60 to rotate at high speed, thus pulverizing the ingredients. When the input rack 31 rotates in reverse, the output rack 351 drives the mixing blade assembly 60 to rotate at a lower speed, thus mixing the pulverized ingredients and performing other functions such as kneading dough, thereby better meeting user needs. Furthermore, when the motor 20 rotates forward or in reverse, the forward / reverse speed switching device 30 can automatically switch between high and low speeds, resulting in different output speeds for forward and reverse rotation. This application does not require a control circuit or control chip to achieve high-speed and low-speed switching, thus eliminating the need for circuit redesign, making implementation easier, and reducing overall cost.

[0036] In the illustrated embodiment, the lifting mechanism 36 includes an internal thread 361 disposed inside the input frame 31 and an external thread 362 disposed outside the shift member 32, wherein the internal thread 361 and the external thread 362 engage. Through the engagement of the internal thread 361 and the external thread 362, rotation of the input frame 31 allows the shift member 32 to rise or fall, and the structure is simple and easy to assemble.

[0037] When the input frame 31 begins to rotate forward, the shifting component 32 is engaged with the low-speed drive component 34. The low-speed drive component 34 limits the shifting component 32 in the circumferential direction, so that the shifting component 32 can only descend and cannot rotate with the input frame 31. When the input frame 31 begins to rotate in reverse, the shifting component 32 is engaged with the high-speed drive component 33. The high-speed drive component 33 limits the shifting component 32 in the circumferential direction, so that the shifting component 32 can only rise and cannot rotate with the input frame 31.

[0038] The shifting component 32 includes a high-speed stop position 321 disposed at one end of the external thread 362 and a low-speed stop position 322 disposed at the other end of the external thread 362. The input frame 31 includes a high-speed stop surface 311 corresponding to the high-speed stop position 321 and a low-speed stop surface 312 corresponding to the low-speed stop position 322. When the input frame 31 rotates forward, the shifting component 32 descends until the high-speed stop position 321 and the high-speed stop surface 311 abut against each other. At this time, the input frame 31 drives the shifting component 32 to rotate forward together. When the input frame 31 rotates in reverse, the shifting component 32 rises until the low-speed stop position 322 and the low-speed stop surface 312 abut against each other. At this time, the input frame 31 drives the shifting component 32 to rotate in reverse together. In this way, the shifting component 32 completes the switching between lifting and rotating.

[0039] In the illustrated embodiment, the input frame 31 includes a high-speed stop groove 313 and a stop block 314 disposed within the high-speed stop groove 313, with the high-speed stop surface 311 disposed on the stop block 314. During assembly, the shifting component 32 is first installed into the input frame 31, and then the stop block 314 is installed into the high-speed stop groove 313, making assembly more convenient.

[0040] The high-speed stop groove 313 is tapered, wider at the top and narrower at the bottom. The shape of the stop block 314 matches the high-speed stop groove 313, and the stop block 314 is inserted into the high-speed stop groove 313 from the outside of the input frame 31. In this way, the high-speed stop groove 313 can limit the stop block 314 in the vertical direction, preventing the stop block 314 from detaching from the high-speed stop groove 313 under the action of gravity.

[0041] The input frame 31 includes a bearing 315 disposed on the outside of the stop block 314. The bearing 315 can limit the stop block 314 on the outside of the stop block 314, and make the structure of the input frame 31 more stable and less prone to shaking.

[0042] In another embodiment, the lifting mechanism 36 includes a spiral guide groove disposed inside the input frame 31 and a guide post disposed outside the shift member 32, the guide post being slidably engaged with the spiral guide groove; or, the lifting mechanism 36 includes a guide post disposed inside the input frame 31 and a spiral guide groove disposed outside the shift member 32, the guide post being slidably engaged with the spiral guide groove. Through the engagement of the guide post and guide groove, rotation of the input frame 31 allows the shift member 32 to rise or fall, and the structure is simple and easy to assemble.

[0043] In the illustrated embodiment, the low-speed drive component 34 includes a rotating shaft 341 and a low-speed drive block 342. The first sun gear 352 is fixed to the bottom end of the rotating shaft 341, and the low-speed drive block 342 is fixed to the top end of the rotating shaft 341. Thus, the rotating shaft 341 and the low-speed drive block 342 are manufactured separately and then assembled together, making manufacturing easy. In another embodiment, the rotating shaft 341 and the low-speed drive block 342 are integrally formed.

[0044] The top end of the rotating shaft 341 is provided with a flat part 3411, and the low-speed drive block 342 is provided with a flat part hole 3421 that mates with the flat part 3411. The mating of the flat part 3411 and the flat part hole 3421 makes the fit between the rotating shaft 341 and the low-speed drive block 342 more reliable and prevents relative rotation.

[0045] The low-speed drive block 342 is provided with a low-speed drive protrusion 3429, and the shift member 32 is provided with a low-speed drive groove 329 corresponding to the low-speed drive protrusion 3429. The shift member 32 and the low-speed drive block 342 are joined together by the cooperation of the low-speed drive protrusion 3429 and the low-speed drive groove 329. The cooperation of the low-speed drive protrusion 3429 and the low-speed drive groove 329 allows for a more convenient and reliable joining of the shift member 32 and the low-speed drive block 342. In the illustrated embodiment, the low-speed drive protrusion 3429 extends in the vertical direction, and the low-speed drive groove 329 penetrates the shift member 32 in the vertical direction, but this is not a limitation.

[0046] The high-speed drive component 33 is provided with a high-speed drive protrusion 339, and the shift component 32 is provided with a high-speed drive groove 328 corresponding to the high-speed drive protrusion 339. The shift component 32 and the high-speed drive component 33 are joined together by the cooperation of the high-speed drive protrusion 339 and the high-speed drive groove 328. The cooperation of the high-speed drive protrusion 339 and the high-speed drive groove 328 makes it easier and more reliable to join the shift component 32 and the high-speed drive component 33 together.

[0047] In the illustrated embodiment, the high-speed drive component 33 has a downwardly extending latching portion 337, and the output frame 351 has a latching groove 3517 corresponding to the latching portion 337. The latching portion 337 and the latching groove 3517 cooperate to allow the output frame 351 to rotate together with the high-speed drive component 33. Thus, by engaging the latching portion 337 and the latching groove 3517, the high-speed drive component 33 can rotate together with the output frame 351.

[0048] The input frame 31 is equipped with a second sun gear 316 and a second planetary gear 317. The second sun gear 316 is connected to the motor shaft, and the second planetary gear 317 meshes with the second sun gear 316 and the gear ring 354. The gear shaft of the second planetary gear 317 is fixed to the input frame 31. By setting the second sun gear 316 and the second planetary gear 317, the motor shaft of the motor 20 can be decelerated before being transmitted to the input frame 31.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
