[0038] The present application provides a transmission system, including a driving member, a driven member, a first transmission assembly and a second transmission assembly. The first transmission assembly is drivably connected to the driving member and the driven member only in a first direction, and the first transmission assembly can transmit between the driving member and the driven member at the beginning stage of the actuation of the driving member, and does not transmit in the subsequent stage of the actuation of the driving member. The second transmission assembly is drivably connected to the driving member and the driven member only in a second direction, and the second transmission assembly can transmit between the driving member and the driven member at the beginning stage of the actuation of the driving member, and does not transmit in the subsequent stage of the actuation of the driving member. The first direction is opposite to the second direction, and when one of the first transmission assembly and the second transmission assembly is in a transmission state, the other is in a non-transmission state.

[0039] The present application also provides a food processor, comprising a container, a heating component, a stirrer, the above-mentioned transmission system and a driver. The container is used to hold cooking materials. The heating component can approach or move away from the container and heat the container. The stirrer is rotatably arranged in the container. The active member in the transmission system is used to connect with the stirrer to drive the stirrer to rotate. The driven member in the transmission system is used to drive the heating component to approach or move away from the container. The driver is used to drive the active member to operate.

[0040] The transmission system and the food processor are described below with reference to a food processor. In the following embodiments, the transmission system is applied to the food processor.

[0041] Figure 1 and Figure 2 They are the three-dimensional structural diagram and exploded diagram of the food processor. Figure 1 and Figure 2 As shown, the food processor includes a cup body 10 and a main body 20. The cup body 10 is detachably arranged on the top of the main body 20, so as to facilitate the transfer of cooking materials and the cleaning of the cup body 10. The main body 20 is used to support the cup body 10 and provide power and heat to the cup body 10 to cook the cooking materials in cooperation with the cup body 10. The cooking materials are, for example, soybeans and water, and soy milk can be prepared through the cooking operation.

[0042] Figure 3 and Figure 4 They are a cross-sectional view and a three-dimensional structural schematic diagram of the cup body 10 respectively. Figure 5 1 is a schematic diagram of the three-dimensional structure of the bottom of the cup body 10, and the bottom of the cup body 10 specifically refers to the bottom wall 112 and the connecting wall 1112 in the container shell 11. Figures 3 to 5As shown, the cup body 10 includes a container shell 11, a container 12, a knife group 13, a transmission assembly 14 and a cup cover 15. The container shell 11 includes a side wall 111 and a bottom wall 112. The side wall 111 and the bottom wall 112 are arranged to form a first cavity 113 for accommodating the container 12. The top end of the first cavity 113 is open to facilitate the user to operate the container 12. Specifically, the side wall 111 includes a side wall body 1111 and a connecting wall 1112. The side wall body 1111 is generally conical, and the outer diameter of the top end is smaller than the outer diameter of the bottom end. The connecting wall 1112 is generally cylindrical, integrally formed with the bottom wall 112, embedded in the bottom end of the side wall body 1111, and detachably connected to the side wall body 1111. During the manufacturing process, the side wall body 1111 is a part, and the connecting wall 1112 and the bottom wall 112 are a part. After assembly, the connecting wall 1112 is fixedly connected to the side wall body 1111, and the two together form the side wall 111. The bottom wall 112 is detachable, which makes it easier to assemble the container 12 into the first cavity 113. The container 12 is used to hold cooking materials. The container 12 can form a second cavity 121 with a top opening, and the cooking materials are held in the second cavity 121. The user can load or pour out the cooking materials through the top opening of the container 12, and can also clean the inner wall of the container 12 through the opening.

[0043] The container 12 is rotatably connected to the bottom wall 112 of the container housing 11 through the transmission assembly 14 so as to be able to rotate around its own axis. The transmission assembly 14 includes a cooking shaft 141, a bearing 142 and two bearings 143.

[0044] A bearing hole 112c is provided in the center of the bottom wall 112. A bearing seat 123 protruding downward is provided in the center of the bottom of the container 12, and a bearing hole 1231 penetrating the bottom of the container 12 is provided in the bearing seat 123. The bearing seat 123 of the container 12 is inserted into the bearing hole 112c and is rotatably connected to the bottom wall 112 through the bearing 142. The cooking shaft 141 is inserted into the bearing hole 1231 and is rotatably connected to the bearing seat 123 through the bearing 143. The upper end of the cooking shaft 141 extends into the container 12 and is connected to the knife assembly 13. Both the bearing 142 and the bearing 143 are one-way bearings. A one-way bearing is a bearing that can realize a rotational connection in one direction and is locked in the opposite direction. In this embodiment, when the cooking shaft 141 rotates, one of the bearings 142 and 143 is in a rotationally connected state, and the other is in a locked state. When the cooking shaft 141 rotates forward, the bearing 142 is in a locked state, the bearing 143 is in a rotational connection state, and the cooking shaft 141 only drives the knife group 13 to rotate. At this time, the cooking machine performs a crushing operation to process the cooking materials to obtain slurry. When the cooking shaft 141 rotates reversely, the bearing 142 is in a rotational connection state, the bearing 143 is in a locked state, and the cooking shaft 141 drives the knife group 13 and the container 12 to rotate at the same time. At this time, the cooking machine performs a centrifugal operation on the slurry. By controlling the rotation direction of the cooking shaft 141, the cooking machine can selectively perform a crushing operation or a centrifugal operation. When the rotation speed of the container 12 reaches a predetermined rotation speed, the slurry runs toward the inner wall of the container 12 under the action of centrifugal force and contacts the inner wall of the container 12, at least part of the slag (i.e., solid particles such as food residues in the slurry) adheres to the inner wall of the container 12, and the slurry (i.e., the liquid with high fluidity in the slurry) flows back to the bottom of the container 12, thereby realizing the centrifugal separation of the slurry.

[0045] The knife group 13 is arranged in the second cavity 121 and at the top of the cooking shaft 141. It can rotate under the drive of the cooking shaft 141 to crush the cooking materials to obtain slurry. The knife group 13 is an example of a stirrer. In this embodiment, the knife group 13 also has a stirring function. The knife group 13 includes a cutting knife 131 and a grinding knife 132. The cutting knife 131 is used to cut the cooking materials. The bottom of the container 12 is provided with grinding teeth 122, and the grinding knife 132 is used to cooperate with the grinding teeth 122 to grind the cut cooking materials.

[0046] The cup cover 15 is detachably covered on the top of the container shell 11 and the container 12. The cup cover 15 includes an outer cover 151, a bearing seat 152, an inner cover 153, a hollow column 154 and a bearing 155. The outer cover 151 is snap-connected to the container shell 11 to seal the top opening of the container shell 11. The bearing seat 152 protrudes downward from the central area of ​​the outer cover 151. The inner cover 153 is embedded in the opening at the top of the container 12, fixed relative to the container 12 by friction, and cannot rotate relative to the container 12. The hollow column 154 is fixed in the center of the inner cover 153 and is rotatably connected to the bearing seat 152 through the bearing 155. The hollow column 154 connects the second cavity 121 with the external environment so that the hot air in the container 12 can escape through the hollow column 154. The bearing 155 is a bidirectional bearing. Due to the bearing 155, when the food processor performs centrifugal operation, the inner cover 153 can rotate with the container 12 without affecting the rotation of the container 12. Since the inner cover 153 and the outer cover 151 are inseparable, the container 12 and the container shell 11 can be opened or sealed synchronously. The cup cover 15 can prevent liquid from splashing during the operation of the food processor. In this embodiment, the cup cover 15 is not necessary.

[0047] Figure 6 is a cross-sectional view of a food processor. Figure 6 As shown, the body 20 includes a base 21, a heating component 22 and a host.

[0048] Please also read Figure 2 and Figure 3 The base 21 is a hollow shell and forms a cavity 21a with an opening at the top. A locking assembly 211 is disposed at the top of the base 21. A snap-fit ​​portion 1112a is disposed at the bottom of the side wall 111 of the container shell 11, and the snap-fit ​​portion 1112a is snap-fitted with the locking assembly 211 to detachably mount the container shell 11 on the base 21.

[0049] like Figure 6 As shown, the heating component 22 is disposed on the base 21, and can rise to approach the bottom of the container 12, or fall to move away from the bottom of the container 12 when the container 12 is detachably assembled on the base 21. Specifically, the heating component 22 is located below the container 12, at least a portion of which is disposed in the cavity 21a of the base 21, and is movably connected to the base 21 so as to be able to move up and down relative to the base 21.

[0050] Figure 7 yes Figure 6 AA section view. Figure 6 and Figure 7As shown, in order to enable the heating component 22 to move along a predetermined path, the base 21 has a guide portion 217, and the heating component 22 has a guide portion 2221a, and the guide portion 2221a and the guide portion 217 are slidably matched in the direction in which the heating component 22 moves. Specifically, the guide portion 217 and the guide portion 2221a are respectively arranged on a pair of opposite surfaces of the base 21 and the heating component 22, the guide portion 217 is a column extending in the moving direction of the heating component 22, and the guide portion 2221a is a groove extending in the moving direction of the heating component 22. In this embodiment, the guide portion 217 is arranged on the cavity wall of the cavity 21a of the base 21. The guide portion 2221a is arranged on the outer edge of the heating component 22. Of course, in other embodiments, the positions of the guide portion 217 and the guide portion 2221a can also be interchanged, that is, the guide portion 217 is arranged on the heating component 22, and the guide portion 2221a is arranged on the base 21.

[0051] The heating component 22 can also generate heat by itself, so as to heat the container 12 when it is close to the bottom of the container 12, thereby heating the cooking materials in the container 12. Furthermore, when the heating component 22 contacts the bottom of the container 12, it heats the container 12 to improve the heat transfer efficiency.

[0052] Figure 8 3D schematic diagram of the heating component 22 in the food processor. Figure 5 and Figure 8 As shown, in order to enable the heating component 22 to heat the bottom of the container 12, a first through hole 112a is provided on the bottom wall 112, so that at least a portion of the heating component 22 can extend into the first cavity 113 and fit with the bottom of the container 12. Specifically, the number of the first through holes 112a on the bottom wall 112 is several. The upper surface of the heating component 22 has heating protrusions 2211a corresponding to the first through holes 112a one by one. Avoidance grooves 2211b matching the shape of the bottom wall 112 are formed between the heating protrusions 2211a. When the heating component 22 approaches the bottom of the container 12, the heating protrusions 2211a can pass through the first through holes 112a on the bottom wall 112, and the bottom wall 112 is at least partially accommodated in the avoidance grooves 2211b. In this embodiment, the bottom wall 112 has three spokes 112b distributed radially. The first through hole 112a is formed between two adjacent spokes 112b. The shape of each first through hole 112a is generally fan-shaped. The shape and size of the heating protrusion 2211a match the first through hole 112a. When the heating component 22 approaches the bottom of the container 12, the spokes 112b are accommodated in the avoidance grooves 2211b between adjacent heating protrusions 2211a. A plurality of first through holes 112a are provided on the bottom wall 112 so that the heating component 22 can contact the bottom of the container 12 as much as possible, thereby improving the heating efficiency.

[0053] The main machine is used to drive the knife assembly 13 and / or the container 12 to rotate, and to drive the heating component 22 to rise and fall.

[0054] Figures 9 to 12 In order, there are a three-dimensional structural diagram of the main unit in the body 20 of the food processor, a cross-sectional view, an exploded view from one perspective, and an exploded view from another perspective. Figures 9 to 12 The drive is omitted.

[0055] like Figure 6 , Figures 9 to 12 As shown, the main machine includes a transmission system 23, a mounting seat 24, a rotating member 25, bearings 271, 272, a fifth gear 273, and a driver (motor 26).

[0056] The mounting seat 24 is fixedly arranged in the cavity 21a of the base 21, and is used to install the remaining parts of the host. The mounting seat 24 includes a lower gear box cover 242 and an upper gear box cover 241. The lower gear box cover 242 is fixedly connected to the cavity wall of the cavity 21a. The lower gear box cover 242 is provided with an open first recess 2421 on the upper side, and an open second recess 2422 on the lower side. The upper gear box cover 241 is covered on the lower gear box cover 242, and is detachably connected to the lower gear box cover 242.

[0057] The transmission system is disposed in the first recess 2421. The transmission system includes a driving shaft 231, a driven shaft 232, a first transmission assembly, and a second transmission assembly. The driving shaft 231 and the driven shaft 232 are examples of a driving member and a driven member, respectively. In other embodiments, the driving shaft 231 and the driven shaft 232 may also be replaced by objects of other shapes, for example, a cylinder with a rectangular cross section.

[0058] The upper and lower ends of the driving shaft 231 respectively penetrate the upper gear box cover 241 and the lower gear box cover 242, and are rotatably connected to the upper gear box cover 241 and the lower gear box cover 242 through bearings 271 and 272. When the cup body 10 is set on the base 21, the upper end of the driving shaft 231 is plugged into and matched with the cooking shaft 141 to drive the cooking shaft 141 to rotate, thereby driving the knife group 13 and / or the container 12 to rotate.

[0059] The driven shaft 232 is parallel to the driving shaft 231 and is arranged at intervals. The upper and lower ends of the driven shaft 232 are respectively inserted into the grooves on the opposite sides of the upper gear box cover 241 and the lower gear box cover 242, and can rotate. In order to limit the rotation range of the driven shaft 232, a second limiting portion 239 is also fixed to the lower end of the driven shaft 232. The second limiting portion 239 can be integrally formed with the driven shaft 232. Correspondingly, a third limiting portion 2425 is also provided on the lower gear box cover 242. The third limiting portion 2425 is used to conflict with the second limiting portion 239 to limit the rotation of the driven shaft 232. The third limiting portion 2425 can be an annular groove extending around the driven shaft 232, and the second limiting portion 239 is accommodated in the annular groove. In other embodiments, the third limiting portion 2425 can also be provided on the upper gear box cover 241, and correspondingly, the second limiting portion 239 is provided on the upper end of the driven shaft 232.

[0060] The first transmission assembly connects the driving shaft 231 and the driven shaft 232. When the driving shaft 231 rotates along the first direction D1, the first transmission assembly is in a transmission state, and the first transmission assembly can be transmission-connected to the driving shaft 231 and the driven shaft 232. The first transmission assembly can transmit between the driving shaft 231 and the driven shaft 232 at the beginning of the actuation of the driving shaft 231, and does not transmit in the subsequent stages of the actuation of the driving shaft 231. When the driving shaft 231 rotates along the second direction D2 opposite to the first direction D1, the first transmission assembly is in a non-transmission state. Specifically, the first transmission assembly includes a first gear 233, a second gear 234 and a first one-way bearing 235. The outer peripheral side wall of the first gear 233 is covered with transmission teeth along the circumferential direction. The first one-way bearing 235 is an example of a first one-way rotating member. The first gear 233 is rotatably sleeved on the driving shaft 231 in only one direction through the first one-way bearing 235. The second gear 234 is fixedly sleeved on the driven shaft 232. A portion of the outer peripheral side wall of the second gear 234 along the circumferential direction has transmission teeth, forming a first toothed area 2342. The remaining portion of the outer peripheral side wall of the second gear 234 along the circumferential direction has no transmission teeth, forming a first toothless area 2341. The first gear 233 and the second gear 234 (the first toothed area 2342) are meshed with each other. When the driving shaft 231 rotates along the first direction D1, the first one-way bearing 235 is in a fixed connection state, the driving shaft 231 drives the first gear 233 to rotate, and the first gear 233 and the second gear 234 are driven, so that the driven shaft 232 rotates along the third direction D3. When the first gear 233 intersects with the first toothless area 2341 of the second gear 234, the driving shaft 231 no longer drives the driven shaft 232 to rotate, and the first transmission assembly does not transmit. When the driving shaft 231 rotates along the second direction D2, the first one-way bearing 235 is in a rotational connection state, the driving shaft 231 cannot drive the first gear 233 to rotate, and the first transmission assembly is in a non-transmission state.

[0061] The second transmission assembly connects the driving shaft 231 and the driven shaft 232. When the driving shaft 231 rotates along the second direction D2, the second transmission assembly is in a transmission state, and the second transmission assembly can be transmission-connected to the driving shaft 231 and the driven shaft 232. The second transmission assembly can transmit between the driving shaft 231 and the driven shaft 232 at the beginning of the actuation of the driving shaft 231, and does not transmit in the subsequent stages of the actuation of the driving shaft 231. When the driving shaft 231 rotates along the first direction D1, the second transmission assembly is in a non-transmission state. Specifically, the second transmission assembly includes a third gear 236, a fourth gear 237 and a second one-way bearing 238. The outer peripheral side wall of the third gear 236 is covered with transmission teeth in the circumferential direction. The second one-way bearing 238 is an example of a second one-way rotating member. The third gear 236 is rotatably sleeved on the driving shaft 231 in only one direction through the second one-way bearing 238. The fourth gear 237 is fixedly sleeved on the driven shaft 232. A portion of the outer peripheral side wall of the fourth gear 237 along the circumferential direction has transmission teeth, forming a second toothed area 2372. The remaining portion of the outer peripheral side wall of the fourth gear 237 along the circumferential direction has no transmission teeth, forming a second toothless area 2371. The third gear 236 and the fourth gear 237 (the second toothed area 2372) are meshed with each other. When the driving shaft 231 rotates along the second direction D2, the second one-way bearing 238 is in a fixed connection state, the driving shaft 231 drives the third gear 236 to rotate, and the third gear 236 and the fourth gear 237 are driven, so that the driven shaft 232 rotates along the fourth direction D4 opposite to the third direction D3. When the third gear 236 intersects with the second toothless area 2371 of the fourth gear 237, the driving shaft 231 no longer drives the driven shaft 232 to rotate, and the second transmission assembly does not transmit. When the driving shaft 231 rotates along the first direction D1, the second one-way bearing 238 is in a rotationally connected state, the driving shaft 231 cannot drive the third gear 236 to rotate, and the second transmission assembly is in a non-transmission state.

[0062] From the above analysis, it can be known that when the driving shaft 231 continuously rotates along the first direction D1, under the transmission action of the first transmission component, the driving shaft 231 drives the driven shaft 232 to rotate along the third direction D3 in the initial stage of rotation (the rotation range of the driven shaft 232 is less than 1 circle), and the driving shaft 231 no longer drives the driven shaft 232 to rotate in the subsequent stage of rotation. In the subsequent stage of rotation, the driving shaft 231 rotates and the driven shaft 232 is stationary. When the driving shaft 231 continuously rotates along the second direction D2, under the transmission action of the second transmission component, the driving shaft 231 drives the driven shaft 232 to rotate along the fourth direction D4 in the initial stage of rotation (the rotation range of the driven shaft 232 is less than 1 circle), and the driving shaft 231 no longer drives the driven shaft 232 to rotate in the subsequent stage of rotation. In the subsequent stage of rotation, the driving shaft 231 rotates and the driven shaft 232 is stationary.

[0063] Fig.13 yes Fig.10 In the CC section view, Fig.13 Only the second gear 234, the fourth gear 237 and the driven shaft 232 are shown. In this embodiment, the second gear 234 and the fourth gear 237 have the same outer diameter, but in order to facilitate the distinction between the second gear 234 and the fourth gear 237, Fig.13 The outer diameters of the second gear 234 and the fourth gear 237 are set to be different.

[0064] like Fig.13 As shown, the first toothed area 2342 of the second gear 234 and the second toothed area 2372 of the fourth gear 237 both extend in the circumferential direction of the driven shaft 232. The first end 2342a of the first toothed area 2342 exceeds the first end 2372a of the second toothed area 2372. The second end 2342b of the first toothed area 2342 does not reach the second end 2372b of the second toothed area 2372.

[0065] Fig.14 The driving shaft 231 rotates in the first direction D1 in the later stage. Fig.10 BB section view in. Fig.15 The driving shaft 231 rotates in the first direction D1 in the later stage. Fig.10 CC section view in. Fig.14 and Fig.15 Only part of the transmission system 23 is shown. Fig.14 and Fig.15 The status shown is at the same moment.

[0066] like Fig.14 and Fig.15 As shown, when the driving shaft 231 rotates along the first direction D1, the first one-way bearing 235 is in a fixed connection state, and the second one-way bearing 238 is in a rotational connection state. The first gear 233 and the second gear 234 are transmitted, so that the driving shaft 231 drives the driven shaft 232 to rotate along the third direction D3. When the first gear 233 and the second end 2342b of the first toothed area 2342 of the second gear 234 are meshed, the meshing position of the third gear 236 and the fourth gear 237 is located at the side where the second end 2372b of the second toothed area 2372 is away from the second toothless area 2371. In this way, it can be ensured that when the driving shaft 231 rotates along the second direction D2, the third gear 236 and the fourth gear 237 are well meshed.

[0067] Fig.16 The driving shaft 231 rotates in the second direction D2 in the later stage. Fig.10 CC section view in. Fig.17 The driving shaft 231 rotates in the second direction D2 in the later stage. Fig.10 BB section view in. Fig.16 and Fig.17Only part of the transmission system 23 is shown. Fig.16 and Fig.17 The status shown is at the same moment.

[0068] like Fig.16 and Fig.17 As shown, when the driving shaft 231 rotates along the second direction D2, the second one-way bearing 238 is in a fixed connection state, and the first one-way bearing 235 is in a rotational connection state. The third gear 236 and the fourth gear 237 are driven, so that the driving shaft 231 drives the driven shaft 232 to rotate along the fourth direction D4. When the third gear 236 is meshed with the first end 2372a of the second toothed area 2372 of the fourth gear 237, the meshing position of the first gear 233 and the second gear 234 is located at the side of the first end 2342a of the first toothed area 2342 away from the first toothless area 2341. In this way, it can be ensured that when the driving shaft 231 rotates along the first direction D1, the first gear 233 and the second gear 234 are well meshed.

[0069] like Figures 9 to 12 As shown, the rotating member 25 is located between the lower gear box cover 242 and the upper gear box cover 241. The rotating member 25 is annular and is disposed outside the driving shaft 231 and the driven shaft 232, and outside the first recess 2421. The rotating member 25 can move in a direction (direction) in which the heating assembly 22 approaches or moves away from the container 12. Fig.10 The upper and lower directions) are the rotation axes. Specifically, a column 252 extending along the rotation axis of the rotating member 25 is provided on the rotating member 25. The column 252 is an example of a first guide portion. A groove 2423 extending around the rotation axis of the rotating member 25 is provided on the lower gear box cover 242. The groove 2423 is an example of a second guide portion. The column 252 is at least partially inserted in the groove 2423 and slidably fits around the rotation axis of the rotating member 25 to guide the rotation of the rotating member 25. A first limiting portion 2424 is also provided in the groove 2423. The first limiting portion 2424 is used to interfere with the column 252 to limit the rotation of the rotating member 25. In other embodiments, the groove 2423 and the first limiting portion 2424 may also be provided on the upper gear box cover 241.

[0070] The rotating member 25 has a plurality of transmission teeth, and the plurality of transmission teeth are arranged around the rotating shaft of the rotating member 25. The fifth gear 273 is fixedly sleeved on the upper end of the driven shaft 232. The rotating member 25 is meshed with the fifth gear 273 through the plurality of transmission teeth. When the driven shaft 232 rotates, the rotating member 25 can be driven to rotate.

[0071] The rotational motion of the rotating member 25 can be converted into a linear motion of the heating component 22 along the rotation axis direction of the rotating member 25. Specifically, the rotating member 25 has a transmission surface 251, which is located outside the rotation axis of the rotating member 25, extends around the rotation axis of the rotating member 25 and extends along the rotation axis of the rotating member 25 to form a spiral surface, and the transmission surface 251 is used to conflict with the heating component 22 in a direction inclined to the rotation axis of the rotating member 25. When the rotating member 25 rotates under the drive of the driven shaft 232, it can drive the heating component 22 to rise or fall. In other embodiments, the transmission surface 251 can also be provided on the heating component 22.

[0072] The driver may be a motor 26. At least a portion of the motor 26 is accommodated in the second recess 2422 and is fixedly connected to the lower gear box cover 242. The output shaft of the motor 26 can rotate forward and reverse, and is connected to the driving shaft 231.

[0073] Working process:

[0074] The food processor starts the crushing operation: the motor 26 rotates forward, and only the knife assembly 13 is driven to rotate through the driving shaft 231 . At the same time, the driven shaft 232 drives the heating component 22 to rise and fit the container 12 .

[0075] During or after the cooking materials are crushed, the heating component 22 heats the container 12 to cook the cooking materials.

[0076] After the cooking is completed, the food processor starts the centrifugal operation: the motor 26 reverses, driving the knife assembly 13 and the container 12 to rotate through the driving shaft 231, and at the same time, the driven shaft 232 drives the heating component 22 to descend, so that the heating component 22 is separated from the container 12.

[0077] Beneficial effects of this embodiment:

[0078] In the present application, without adding a driving device, the stirring of the stirrer and the lifting and lowering of the heating component 22 are simultaneously realized by a motor 26. In the present embodiment, the rotation of the knife group 13 and the rotation of the container 12 both realize the stirring function.

[0079] The toothed areas of the second gear 234 and the fourth gear 237 both extend in the circumferential direction of the driven shaft 232, the first end of the toothed area of ​​the second gear 234 exceeds the same end of the toothed area of ​​the fourth gear 237, and the second end of the toothed area of ​​the second gear 234 does not reach the same end of the toothed area of ​​the fourth gear 237. Thus, it is ensured that the first gear 233 and the second gear 234 are stably meshed, or the third gear 236 and the fourth gear 237 are stably meshed in the initial stages of the driving shaft 231 rotating in the first direction and the second direction, respectively.

[0080] The food processor is provided with an upper gear box cover 241 and a lower gear box cover 242. An open first recess 2421 is provided on the upper side of the lower gear box cover 242. The upper gear box cover 241 is covered on the lower gear box cover 242 and is detachably connected to the lower gear box cover 242. The transmission system 23 is provided in the first recess 2421, which can be kept clean. In addition, it is also convenient to assemble the transmission system 23. An open second recess 2422 is provided on the lower side of the lower gear box cover 242, and at least part of the motor 26 is accommodated in the second recess 2422 and is fixedly connected to the lower gear box cover 242. Compared with the fixed connection between the motor 26 and the base 21, the main structure of the food processor is more compact. In the process of assembling the food processor, the main machine can be assembled first, and then assembled into the cavity 21a of the base 21. Thereby, the assembly efficiency can be improved.

[0081] The heating component 22 is disposed on the base 21 and can be close to or away from the container 12. Therefore, when the heating component 22 is away from the container 12, even if liquid flows down the outer wall of the container 12, it will not flow directly onto the heating component 22. In addition, since the heating component 22 is detachable from the container 12, the heating component 22 will not be stained with liquid (water) when the container 12 is cleaned. This embodiment can reduce the probability of the heating component 22 being stained with liquid, thereby reducing the risk of the heating component 22 being short-circuited or damaged.

[0082] The heating assembly 22 is disposed on the main body 20, which reduces the weight of the cup body 10 compared to being fixed on the container 12. When the cup body 10 is transferred, the user can operate more conveniently.

[0083] The heating component 22 is disposed on the main body 20 , which lowers the center of gravity of the food processor compared to being fixed on the container 12 , making the food processor more stable during operation.

[0084] In this embodiment, the container 12 is rotatable, and the heating component 22 is disposed on the body 20 , which reduces the load of the motor 26 compared to being fixed on the container 12 .

[0089] Structure three: The transmission system 23 includes a driving shaft 231, a driven shaft 232, a first gear 233, a second gear 234, a first one-way bearing 235, a third gear 236, a fourth gear 237 and a second one-way bearing 238. The first gear 233 is fixedly sleeved on the driving shaft 231. The second gear 234 is rotatably sleeved on the driven shaft 232 in only one direction through the first one-way bearing 235.

[0090] Figure 1 In the illustrated embodiment, the output shaft of the motor 26 is coaxially connected to the driving shaft 231. Generally, the axial dimension of the motor 26 at the output shaft is large, so that the motor 26 occupies a large space in the up and down directions, thereby making the overall height of the food processor higher. In other embodiments, in order to reduce the overall height of the food processor, the output shaft of the motor 26 can be tilted relative to the driving shaft 231. Specifically, the driver includes a motor 26 and an intersecting shaft transmission assembly (not shown). The output shaft of the motor 26 intersects with the driving shaft 231 and can rotate forward and reverse. The intersecting shaft transmission assembly can be a prior art for transmitting between two intersecting shafts. The output shaft of the motor 26 drives the driving shaft 231 to rotate through the intersecting shaft transmission assembly. For example, the output shaft of the motor 26 is perpendicular to the driving shaft 231. When the food processor is in use, the conveying shaft of the motor 26 is placed horizontally. As a result, the overall height of the food processor can be reduced.
