As shown in fig. 7 and 8, the user rotates the latch handle 125 to drive the latch gear 124 to rotate, and the latch gear 124 drives the latch 1231 on the latch ring 123 to rotate through the transmission of the first tooth 1232 and the second tooth 1241, so as to lock or separate the latch 1231 and the slot 2111 (see fig. 3), thereby achieving the detachable connection between the cup 200 and the base 100. The length of the through hole 1211 ensures that the latch 1231 can be positioned and guided from the locking position to the releasing position. The positioning post 1212 cooperates with the latch 1231 such that the positioning post 1212 supports the latch 1231 when the latch 1231 is in the disengaged position and also facilitates positioning of the cup 200.

The second connector 132 is coaxially fixed to the top end of the driving shaft 1311. The elastic pad 133 is sleeved outside the second connector 132. The second socket connector 132 is used for being plugged and matched with the first socket connector 265 in the cup 100 to form a coupling, so as to transmit the power of the motor 131 to the cup 100. The elastic pad 133 may be made of rubber material and is sandwiched between the first connector 265 and the second connector 132 to reduce noise generated during the power transmission process.

As shown in fig. 6, the power supply assembly 140 includes a first electrode 141, a mount 142, and a driver 143. The first electrode 141 is disposed on the mounting base 142. The mounting base 142 is movably coupled to the support cap 121 and can be moved toward or away from the cup body 200. The driving unit 142 is used to drive the mounting seat 142 to move so as to contact with or separate from the second electrode 240 in the cup 200, thereby selectively supplying power to the cup 200.

The input panel is disposed on an outer surface of the base housing 110 to input a control command.

As shown in fig. 5, the driving board 150 is disposed in the cavity 111, and is electrically connected to the power source 130 and the input panel, respectively, for receiving a control command transmitted from the input panel, and controlling the power source 130 to operate according to the control command, that is, controlling the start, stop, forward, and reverse rotation of the motor 131, or controlling the rotation speed of the motor 131. Referring to fig. 6, the driving plate 150 is further electrically connected to a driver 143 (see fig. 6) in the power supply assembly 140, and is used for controlling the driver 143 to operate according to a control command, so as to control the power supply assembly 140 to supply power to or cut off power from the cup 200.

The cup body 200:

fig. 9 is a cross-sectional view of a cup body in a first embodiment of the food processing apparatus of the present application.

As shown in fig. 9, the cup 200 includes a container housing 210, a container 220, a heat generating plate 230, a second electrode 240, an operating assembly 250, and a driving assembly 260.

The vessel shell 210 includes a shell body 211, a second hollow column 212, and an outer cover 213.

The bottom of the housing body 211 is provided with a locking slot 2111, and the locking slot 2111 is matched with a locking buckle 1231 of the locking buckle assembly 120 (see fig. 3), and is detachably fixed on the top of the base 100. The housing body 211 forms a cavity open at the top end.

The outer lid 213 detachably covers the top end of the housing body 211. Specifically, the outer cover 213 is snap-coupled with the housing main body 211. Of course, a threaded connection could be used instead.

The second hollow post 212 is described in detail below in the section of the drive assembly 260.

The container 220 is a rotational body rotatably received in the container housing 210 about its own axis and rotatably connected to the container housing 210. By isolating the container housing 210 from the outside, accidental injury accidents during rotation are avoided. The container 220 is rotatably engaged with the container housing 210, and the weight of the container 220 is transmitted to the container housing 210, so that the influence of the weight transmitted to the power source 130 on the service life of the power source 130 can be avoided. The specific structure by which the reservoir 220 may be rotatably engaged with the reservoir housing 210 is described below in the section of the drive assembly 260.

As shown in fig. 9, the container 220 includes a container body 221, a first hollow column 222, and an inner lid 223.

The container body 221 is a rotating body and forms a cavity 2211 with an open upper end. The user can fill in food or slurry to be cooked through the opening, can pour out the slurry cooked in the cavity 2211 through the opening, and can clean the inner wall of the container body 221 through the opening. A grinding tooth 2212 is provided on the bottom surface of the container main body 221. The grinding teeth 2212 are adapted to cooperate with the operating assembly 250 to grind food.

The first hollow column 222 protrudes downward from the bottom of the container body 221, and is integrally formed with the container body 221. The first hollow column 222 is coaxial with the axis of the container body 221 for bearing force to rotate the container body 221. The bottom of the container body 221 is provided with a through hole which communicates the space between the cavity 2211 and the first hollow column 222.

The inner cap 223 is detachably closed over the opening at the top of the container body 221, and a vent hole is provided at the center of the inner cap 223 so that hot air inside the container 220 can escape.

As shown in fig. 9, the heating plate 230 is accommodated in a cavity formed by the housing body 211, attached to an outer wall surface of the bottom of the container body 221, and used for heating food in the container 220 after being electrified. The heating plate 230 is a revolving body and is coaxial with the container 220 to avoid affecting the rotating stability of the container 220.

As shown in fig. 9, the second electrode 240 is accommodated in the cavity formed by the housing body 211 and is fixedly disposed at the bottom of the heating plate 230 for cooperating with the power supply assembly 140 to supply power to the heating plate 230. The second electrode 240 is a solid of revolution and is coaxial with the container 220 to avoid affecting the rotational stability of the container 220.

Specifically, as shown in fig. 4 and 6, when the container 220 is not rotated, the driver 143 drives the mounting base 142 to ascend, so that the first electrode 141 is in contact with the second electrode 240 and is conducted, thereby implementing power supply. After the heating is completed, the driver 143 drives the mounting base 142 to descend, so that the first electrode 141 is separated from the second electrode 240, and the power supply is stopped. When grinding food, heat food, can practice thrift grinding time, improve machining efficiency. Because the second electrode 240 is a revolving body, the container 220 stays at any position after rotating, and the contact between the first electrode 141 and the second electrode 240 is not affected.

As shown in fig. 9, the operating member 250 is rotatably provided in the cavity 2211 of the container body 221 to perform a pulverizing operation on the food. In this embodiment, the operating assembly 250 includes a cutting tool 251 and a grinding tool 252. The cutting knife 251 is used to cut the food. The grinding tool 252 is used to grind the cut food in cooperation with the grinding teeth 2212.

Fig. 10 is an enlarged view of the partial view of fig. 9, to more clearly show the structure at the transmission assembly.

As shown in fig. 9 and 10, the transmission assembly 260 includes a rotation shaft 261 and a first one-way bearing 262. The rotating shaft 261 is one example of a power introduction member. The first one-way bearing 262 is an example of a first one-way rotating member. The first one-way bearing 262 may be rotationally coupled in one direction and locked in the opposite direction.

The rotation shaft 261 has one end for introducing power from the power source 130 and the other end for protruding into the container 220 to connect the operating assembly 250.

In this embodiment, the other end (top end) of the shaft 261 extends into the container 220 from the bottom of the container 220. Specifically, the rotating shaft 261 is coaxially inserted in the first hollow column 222. The bottom end of the rotating shaft 261 is connected to the power source 130 (see fig. 3), and is driven by the power source 130 to rotate. The top end of the rotating shaft 261 extends into the cavity 2211 of the container main body 221 through the through hole, and the rotating shaft 261 and the container main body 221 are sealed.

The cutting tool 251 and the grinding tool 252 are both disposed at the top end of the rotating shaft 261 and are driven by the rotating shaft 261 to rotate. In other embodiments, the operating assembly 250 may also include a cutter shaft (not shown), on which the cutting tool 251 and the grinding tool 252 are disposed, and the cutter shaft is connected to the rotating shaft 261 and rotates along with the rotating shaft 261.

The first one-way bearing 262 is configured to be coupled to the container 220 and the rotation shaft 261, and is capable of driving the operation member 250 and the container 220 to rotate simultaneously when the rotation shaft 261 rotates in one direction, and driving only the operation member 250 to rotate when the rotation shaft 261 rotates in the opposite direction to the one direction.

Specifically, the inner ring of the first one-way bearing 262 is fixedly sleeved on the rotating shaft 261. The outer race of the first one-way bearing 262 is embedded in the first hollow post 222. The inner ring and the outer ring of the first one-way bearing 262 can be limited by a key, which is the prior art and is not described herein again. When the first one-way bearing 262 is in a rotation connection state, the rotating shaft 261 can rotate relative to the first hollow column 222; when the first one-way bearing 262 is in a locked state, the rotating shaft 261 and the first hollow column 222 are relatively fixed.

Hereinafter, for the convenience of distinguishing the rotation direction of the rotation shaft 261, the following definitions are made: when the rotating shaft 261 rotates forward, the first one-way bearing 262 is in a rotation connection state; when the rotating shaft 261 rotates reversely, the first one-way bearing 262 is in a locked state. The positive and negative rotation merely means that the rotation shaft 261 rotates in two opposite directions.

When the rotating shaft 261 rotates forwards, the rotating shaft 261 only drives the operating assembly 250 to rotate, crushing operation is carried out, and food is processed to obtain slurry; when the rotating shaft 261 rotates reversely, the rotating shaft 261 simultaneously rotates the operating assembly 250 and the container 220 to perform centrifugal operation on the slurry. By controlling the rotation shaft 261 to rotate forward and backward, the food processor 1000 can selectively perform the crushing operation or the centrifugal operation.

To achieve the rotation of the operating assembly 250 and the container 220, one way is to rotate the operating assembly 250 and the container 220 by two transmission members. When the crushing operation is required, only the operating assembly 250 is driven to rotate; when centrifugation is desired, only the vessel 220 is driven to rotate. Two power sources are needed. In centrifugal operation, only the vessel 220 is driven to rotate, the operating assembly 250 is not moved, the operating assembly 250 rotates relative to the vessel 220, and the operating assembly 250 disturbs slurry in the vessel 220, thereby affecting the centrifugal effect.

In this embodiment, the driving assembly 260 is respectively connected to the container 220 and the operating assembly 250, and can selectively respectively drive the container 220 and the operating assembly 250 to rotate, so that the structure is simple, the occupied space is small, and the cost is low. In addition, the operating assembly 250 and the vessel 220 are relatively static during the centrifugal operation, so that the operating assembly 250 is prevented from disturbing slurry, and the centrifugal effect is ensured.

As shown in fig. 9 and 10, in order to avoid the container 220 from deflecting during rotation and improve the stability of the food processor 1000 during centrifugal operation, the transmission assembly 260 further includes a first bidirectional bearing 263. The first bidirectional bearing 263 does not prevent the rotation shaft 261 and the container 220 from rotating relatively regardless of the forward rotation or the reverse rotation of the rotation shaft 261. The first bidirectional bearing 263 may be a deep groove ball bearing. The inner ring of the first bidirectional bearing 263 is fixedly sleeved on the rotating shaft 261, and the outer ring of the first bidirectional bearing 263 is embedded in the first hollow column 222. The first bidirectional bearing 263 is disposed coaxially with the first unidirectional bearing 262 and spaced apart in the axial direction of the rotating shaft 261. In another embodiment, the shafts 261 may abut against each other in the axial direction. The spacing arrangement can better avoid the container 220 from deflecting during rotation, as compared to mutual abutment.

Further, as shown in fig. 9 and 10, the transmission assembly 260 further includes a sleeve 264. The inner ring of the first bidirectional bearing 263 is non-rotatably sleeved on the rotating shaft 261 by a key, and the outer ring thereof is non-rotatably embedded in the first hollow column 222 by a key. Similarly, the inner ring of the first one-way bearing 262 is non-rotatably sleeved on the rotating shaft 261 by a key, and the outer ring thereof is non-rotatably embedded in the first hollow column 222 by a key. In the axial direction of the rotating shaft 261, the outer ring of the first bidirectional bearing 263 abuts against the position-limiting surface 2221 of the first hollow column 222. The sleeve 264 is sleeved on the rotating shaft 261 and clamped between inner rings of the first one-way bearing 262 and the first two-way bearing 263. The snap ring 265 engaged with the rotating shaft 261 abuts against the inner ring of the first one-way bearing 262. The snap ring 265, the sleeve 264 and the limiting surface 2221 limit the first one-way bearing 262 and the first two-way bearing 263 in the axial direction of the rotating shaft 261. After the snap ring 265 is removed, the first one-way bearing 262, the sleeve 264 and the first two-way bearing 263 can be removed from the rotating shaft 261.

The sleeve 264 limits the first one-way bearing 262 and the first two-way bearing 263 in the axial direction of the rotating shaft 261, and the structure is simple, and the dismounting and the mounting are easy.

As shown in fig. 5 and 10, the drive assembly 260 also includes a first connector 265. The first connector 265 is fixedly disposed at an end of the rotating shaft 261 to be detachably engaged with the power source 130 at the end of the rotating shaft 261, so as to transmit power of the power source 130.

The first connector 265 is detachably fixed to the bottom end of the rotary shaft 261. In another embodiment, the first connector 265 may be integrated with the rotating shaft 261. Specifically, the first connector 265 is sleeve-shaped, opening toward the power source 130. The first connector 265 is disposed coaxially with the rotary shaft 261. The inner wall of the first connector 265 is provided with a plurality of ribs 2651 at intervals in the circumferential direction, and each rib 2651 extends in the axial direction of the rotary shaft 261. The second connector 132 of the power source 130 is shaped to fit the cavity of the first connector 265. the second connector 132 is provided at its outer periphery with a plurality of grooves (not visible) which correspond to the plurality of ribs 2651 in equal and one-to-one correspondence, each groove extending in the axial direction of the drive shaft 1311. In use, the ribs 2651 are engaged with the corresponding grooves to transmit torque.

Because the rotating shaft 261 can be inserted into and pulled out from the power source 130, the base 100 and the cup 200 can be detachably connected with each other.

As shown in fig. 9, the grinding teeth 2212 are subjected to forces during the grinding operation, particularly when food is being ground. If the container 220 is free to rotate, it is not conducive to grinding. For this reason, in the present embodiment, the container 220 is fixed with respect to the container casing 210 when the pulverizing operation is performed; during centrifugation, the reservoir 220 may be rotated relative to the reservoir housing 210.

The specific structure of the container 220 and the container housing 210 for rotational engagement is described below:

as shown in fig. 9, the second hollow column 212 protrudes upward from the bottom of the housing main body 211, and is integrally formed with the housing main body 211. In another embodiment, the second hollow column 212 and the housing body 211 may be formed as separate bodies. The second hollow column 212 coaxially surrounds the first hollow column 222.

Referring also to fig. 10, the transmission assembly 260 further includes a second one-way bearing 266. The second one-way bearing 266 is an example of a second one-way rotating member. The second one-way bearing 266 is configured to be coupled to the vessel 220 and the vessel housing 210, and is capable of allowing the vessel 220 to rotate with respect to the vessel housing 210 when the rotation shaft 261 rotates in one direction and preventing the vessel 220 from rotating with respect to the vessel housing 210 when the rotation shaft 261 rotates in the opposite direction to the one direction.

The second one-way bearing 266 may be rotationally coupled in one direction and locked in the opposite direction.

Specifically, the inner ring of the second one-way bearing 266 is fixedly sleeved outside the first hollow column 222, and the outer ring of the second one-way bearing 266 is fixedly sleeved inside the second hollow column 212. The second one-way bearing 266 is disposed coaxially with the rotating shaft 261.

When the rotating shaft 261 rotates, one of the first one-way bearing 262 and the second one-way bearing 266 is in a rotationally coupled state, and the other is in a locked state.

When the food processor 1000 performs the crushing operation, the second one-way bearing 266 is in a locked state, the container 220 and the container housing 210 are relatively fixed, the first one-way bearing 262 is in a rotation connection state, and the rotating shaft 261 drives the operation assembly 250 to rotate;

when the food processor 1000 performs centrifugal operation, the second one-way bearing 266 is in a rotation connection state, the container 220 can rotate relative to the container shell 210, the first one-way bearing 262 is in a locking state, and the rotating shaft 261 drives the container 220 to rotate.

To prevent yaw when the vessel 220 rotates relative to the vessel housing 210, the transmission assembly 260 further includes a second bi-directional bearing 267, as shown in fig. 9 and 10. Second bidirectional bearing 267 is disposed coaxially with second one-way bearing 266, and abuts second one-way bearing 266 in the axial direction of second one-way bearing 266. In another embodiment, if there is enough space, the second bidirectional bearing 267 and the second unidirectional bearing 266 may be disposed at an interval. An inner ring of the second bidirectional bearing 267 is fixedly sleeved outside the first hollow column 222, and an outer ring of the second bidirectional bearing 267 is fixedly sleeved inside the second hollow column 212. The second bi-directional bearing 267 does not impede the rotation of the vessel 220 relative to the vessel shell 210, whether by comminution or centrifugation. The second bi-directional bearing 267 may be a deep groove ball bearing, as is known in the art.

Beneficial effect of cooking machine implementation mode one:

the container is rotated by the pivot drive, and the ground paste in the container moves towards keeping away from the container center under the effect of centrifugal force to with the inner wall contact of container, the material sediment wherein of ground paste behind the centrifugation is adhered to the inner wall of container, and the bottom to the container is flowed back to the thick liquid, thereby separates the material sediment from the ground paste, reduces and can avoid even filtering operation. In a use scene, when the rotating speed of the container reaches 500 to 5000 revolutions per minute, the slag in the slurry can be adhered to the inner wall of the container. The rotation speed can be set according to the amount and kind of food.

The first one-way rotating member may be implemented in various ways, and the present application is not limited to the first one-way bearing 262. Figure 11 illustrates another alternative embodiment of the first unidirectional rotating member. As shown in fig. 11, the first one-way rotating member includes the ring gear 10 and the ratchet plate 20.

The ring gear 10 may be inserted into the first hollow post 222. The ring gear 10 and the first hollow column 222 may be of a separate structure or an integral structure. The ring gear 10 is annular and has a plurality of teeth 11 formed on an inner periphery thereof.

The ratchet plate 20 may be fixedly sleeved on the rotating shaft 261. The pawl plate 20 is disc-shaped, a plurality of pawls 30 are arranged at intervals on the outer periphery of the pawl plate, and the pawls 30 are in elastic contact fit with the inner gear ring 10.

When pawl disc 20 rotates in a counterclockwise direction in fig. 11 relative to ring gear 10, the distal ends of pawls 30 engage first surfaces 12 of teeth 11 and move relative to each other, and first surfaces 12 exert a force on pawls 30 radially inward of pawl disc 20, so that pawls 30 elastically deform and retract, and pawl disc 20 rotates unimpeded. When pawl plate 20 rotates clockwise in fig. 11 relative to ring gear 10, the ends of pawls 30 abut against second surfaces 13 of teeth 11, and second surfaces 13 exert an outward force on pawls 30 in the radial direction of pawl plate 20, so that pawls 30 elastically deform and expand to hinder rotation of pawl plate 20.

In this embodiment, the rotation shaft 261 can rotate only in the counterclockwise direction in fig. 11, and may replace the first one-way bearing 262. The first one-way rotating member in this embodiment may also replace the second one-way bearing 266 described above.

In this embodiment, the shaft and the power source are pluggable and engaged to each other for transmission. In other embodiments, the rotation shaft 261 and the power source 130 may be in a non-contact transmission manner. For example, the transmission may be performed by a magnetic transmission coupling. The magnetic transmission coupler generally comprises two magnets which are respectively arranged on a driving shaft and a driven shaft, and the transmission of force and torque between the driving shaft and the driven shaft can be realized without direct contact by adopting a magnetic coupling principle. The magnetic transmission coupling is prior art and will not be described herein.

In other embodiments, the outer lid may not be provided in the container housing. That is, the container casing includes only the casing main body. When the cooking machine is used, especially during centrifugal operation, the periphery of the container is protected through the shell main body, and the injury risk caused by rotation of the container can be reduced to a certain extent. The cover opening operation can be reduced once by not arranging the outer cover. In addition, the hot air in the container is also more easily escaped.

In other embodiments, the power source, power supply assembly, drive plate, and input panel in the base may also be disposed in the cup, for example, on the container housing. The base includes only a base shell to support the cup. The cup body uses self electric power to heat the food, and utilizes self power to crush and/or centrifuge the food.

In the present embodiment, the container is rotatably coupled to the container housing, but the present application is not limited thereto. In other embodiments, the container may be pivotally attached to the base. In the case of a small container volume, the container can also be connected to the rotary shaft only in a (unidirectional) rotary manner (neither in rotary connection with the container housing nor in rotary connection with the base).

(second embodiment)

In the first embodiment, the second unidirectional rotating member is disposed at the bottom of the container and sleeved outside the first hollow column. The first hollow column has a larger outer diameter so as to accommodate the first one-way rotating member. This results in a larger size and a heavier weight of the second one-way rotating member, which in turn results in a larger load on the power source. In order to reduce the weight of the second unidirectional rotating member, the two pairs of cup bodies are improved.

Fig. 12 is a sectional view of a cup body in the second embodiment of the food processor of the present application.

As shown in fig. 12, the cup 300 includes a vessel housing 310, a vessel 320, a heat generating plate (not shown), a second electrode (not shown), an operating assembly 350, and a driving assembly 360.

The vessel shell 310 includes a shell body 311, a second hollow column 312, and an outer cover 313.

The housing body 311 is detachably fixed to the top of the base through a locking groove. The housing body 311 forms a cavity open at the top end. The second hollow column 312 protrudes upward from the bottom of the housing body 311 and is integrally formed with the housing body 311.

The outer lid 313 includes an outer lid body 3131 and a third hollow post 3132.

The cover body 3131 detachably covers the top end of the housing body 311. Specifically, the outer cover body 3131 is snap-coupled with the housing body 311. The third hollow pillar 3132 protrudes downward from the central region of the cover body 3131 and is integrally formed with the cover body 3131. The third hollow post 3132 is coaxial with the second hollow post 312.

Container 320 includes a container body 321, a first hollow post 322, and an inner lid 323.

The container body 321 forms an open-topped cavity. The container body 321 is received in the cavity of the housing body 311. The container body 321 is a rotating body.

The first hollow pillar 322 protrudes downward from the bottom of the container body 321 and is integrally formed with the container body 321. The first hollow post 322 is coaxial with the container body 321 and is coaxially disposed within the second hollow post 312 for rotational engagement with the second hollow post 312.

The inner cap 323 includes an inner cap body 3231 and a hollow shaft 3232.

The inner cap body 3231 is fitted into an opening at the top end of the container body 321, and is fixed to the container body 321 by friction. In another embodiment, a stopper structure may be provided so that the inner cap body 3231 is not rotatable with respect to the container body 321 after covering the opening provided at the distal end of the container body 321. The hollow shaft 3232 is fixedly disposed at the center of the inner cap body 3231, coaxially disposed in the third hollow post 3132. Hollow shaft 3232 communicates the cavity of container 320 with the outside environment. The hot air within the container 320 may escape through the hollow shaft 3232.

The transmission assembly 360 includes a rotating shaft 361, two first one-way bearings 362, a first two-way bearing 363, a first connector 365, a second one-way bearing 366, a second two-way bearing 367, and two third two-way bearings 368.

The shaft 361 is coaxially disposed in the first hollow column 322, and has a top end inserted into the container body 321 to connect with the operating assembly 350 and a bottom end fixedly connected with the first connector 365.

The inner rings of the two first one-way bearings 362 are fixedly sleeved on the rotating shaft 361, and the outer rings are fixedly embedded in the first hollow column 322. After the container 320 is filled with food, the power source needs to provide a large torque to the container 320 through the first one-way bearing 362 in order to rotate the container 320. To meet the requirement of large torque, two first one-way bearings 362 are provided in the present embodiment. In another embodiment, more first one-way bearings 362 may be provided, and the plurality of first one-way bearings 362 are distributed in the axial direction of the rotating shaft 361. The greater the number of first one-way bearings 362, the less torque the single first one-way bearing 362 transmits, but at the same time, the weight also increases, which may increase the load of the power source. Therefore, it should be considered comprehensively that the number of the first one-way bearings 362 is reasonably determined.

The inner ring of the first bidirectional bearing 363 is fixedly sleeved on the rotating shaft 361, and the outer ring is fixedly embedded in the first hollow column 322. The first bidirectional bearing 363 and the two first unidirectional bearings 362 are arranged in the axial direction of the rotating shaft 361 and are in contact with each other.

The inner rings of the two third bidirectional bearings 368 are fixedly sleeved outside the first hollow column 322, and the outer rings are fixedly embedded in the second hollow column 312.

The inner ring of the second one-way bearing 366 is fixedly sleeved on the hollow shaft 3232, and the outer ring is fixedly embedded in the third hollow post 3132.

The inner ring of the second bidirectional bearing 367 is fixedly sleeved on the hollow shaft 3232, and the outer ring is fixedly embedded in the third hollow post 3132.

When the rotating shaft 361 rotates, one of the first one-way bearing 362 and the second one-way bearing 366 is in a rotation connection state, and the other one is in a locking state.

When the food processor performs the crushing operation, the second one-way bearing 366 is in a locked state, the container 320 and the container housing 310 are relatively fixed, the first one-way bearing 362 is in a rotation connection state, and the rotating shaft 361 drives the operating component 350 to rotate;

when the food processor is operated centrifugally, the second one-way bearing 366 is in a rotation connection state, the container 320 can rotate relative to the container housing 310, the first one-way bearing 362 is in a locking state, and the rotating shaft 361 drives the container 320 to rotate.

In this embodiment, the second one-way bearing 366 is sleeved outside the hollow shaft 3232, the hollow shaft 3232 is used for ventilation, and the outer diameter is smaller than that of the first hollow column 322. Therefore, the second one-way bearing 366 in this embodiment can be selected to have a smaller size than in the first embodiment. The smaller gauge second one-way bearing 366 weighs less and may reduce the load on the power source.

Both the top and bottom of the container 320 are rotatably connected to the container housing 310. in contrast to the first embodiment (only the bottom is rotatably connected), the container 320 is more stable to rotate during centrifugation and less prone to yaw.

By providing a hollow shaft 3232, the hot air in the container 320 can be better evacuated. Meanwhile, the second one-way bearing 366 is combined with the hollow shaft 3232, so that the structure is simple. In addition, the outer cap 313 is integrally (relatively rotatably) coupled to the inner cap 323, so that the opening operation is simpler. In the first embodiment, the cover needs to be opened twice, and only once in the first embodiment.

The rest of this embodiment can refer to embodiment one, and is not described herein again.

The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow changes made by the following claims and drawings, or directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present disclosure.
