[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] (Embodiment One)

[0042] At present, a cooking machine crushes (cuts and grinds) food to obtain a slurry. The slurry can be understood as a mixture of dregs and liquid. The dregs are mostly insoluble dietary fibers and are relatively large solid particles in volume. The liquid is a liquid with high fluidity in the slurry. In order to achieve a better drinking taste, it is necessary to further filter to separate the dregs and the liquid. In addition to crushing food, the cooking machine of this embodiment can also perform centrifugal treatment on the slurry to separate at least part of the dregs from the slurry without filtration operation. Centrifugal treatment: The container of the cooking machine rotates at a predetermined speed, and the slurry moves away from the center of the container under the action of centrifugal force. After contacting the inner wall of the container, the dregs adhere to the inner wall of the container, so that the dregs are separated from the liquid.

[0043] Figure 1 It is a three-dimensional structure diagram of the first embodiment of the cooking machine of this application. Figure 2 Is Figure 1 An exploded view of the cooking machine.

[0044] As Figure 1 And Figure 2 As shown, the cooking machine 1000 includes a base 100 and a cup body 200. The cup body 200 is detachably arranged on the base 100 to facilitate the transfer of food (slurry) and cleaning. The base 100 is used to provide power and electricity to the cup body 200 to cooperate with the cup body 200 to cook food. The cup body 200 can heat the food according to the electricity provided by the base 100. The cup body 200 can crush and / or centrifuge the food according to the power provided by the base 100.

[0045] The base 100 and the cup body 200 will be introduced in detail below.

[0046] Base 100:

[0047] Figure 3 And Figure 4 Are respectively sectional views of different orientations of the cooking machine. Figure 5 And Figure 6 Are respectively Figure 3 And Figure 4 The enlarged views of the base part in

[0048] As Figure 3 And Figure 4 As shown, the base 100 includes a base housing 110, a latch assembly 120, a power source 130, a power supply assembly 140, a drive board 150, and an input panel (not shown in the figure).

[0049] The base housing 110 is a structural support member for installing the remaining components of the base 100. As Figure 5As shown, the base housing 110 is formed with a cavity 111 having an open top. The opening is generally cylindrical, and the upper edge extends towards the center to form a flange 116. A wind channel 115 is also formed within the cavity 111 to enhance heat dissipation. Anti-vibration pads 112 are fixedly provided at the bottom of the base housing 110. The anti-vibration pads 112 can be made of rubber material and have elasticity to reduce the vibration during the operation of the cooking machine 1000. A tray 113 is also fixedly provided at the bottom end of the opening of the base housing 110. The tray 113 is used to clamp the locking component 120 together with the flange 116. An elastic pad 114 is provided on the tray 113, and the elastic pad 114 is used to be clamped between the locking component 120 and the tray 113 for shock absorption.

[0050] As Figure 3 shown, the locking component 120 is disposed on the top of the base 100. A card slot 2111 is provided at the bottom of the cup body 200, and the locking component 120 is provided with a lock 1231 that cooperates with the card slot 2111. Through the locking or detachment of the lock 1231 and the card slot 2111, the fixation or separation of the cup body 200 and the base 100 is realized.

[0051] Figure 7 is a three-dimensional structural schematic diagram of the locking component in the first embodiment of the cooking machine of the present application, Figure 8 is Figure 7 an exploded view of the locking component.

[0052] Figure 7 and Figure 8 as shown, the locking component 120 includes a support cover 121, a bottom cover 122, a locking ring 123, a locking gear 124, a locking handle 125, and an elastic pad 126.

[0053] As Figure 5 shown, the support cover 121 is embedded at the opening at the top end of the base housing 110. The top of the support cover 121 abuts against the flange 116 at the upper edge of the opening through the elastic pad 126, and its bottom abuts against the tray 113 through the elastic pad 114.

[0054] As Figure 8 shown, the support cover 121 is provided with a through hole 1211. The through hole 1211 is arc-shaped. A positioning post 1212 is provided at the edge of the through hole 1211. A water guide groove 1213 is also formed on the upper end surface of the support cover 121 for draining water. In addition, a fixing post 1214 for installing the power source 130 is provided at the lower end of the support cover 121.

[0055] As Figure 7 and Figure 8 shown, the bottom cover 122 is fixed to the bottom of the support cover 121, and a space for accommodating the locking ring 123 is formed between the bottom cover 122 and the support cover 121.

[0056] The locking ring 123 is rotatably disposed within the space. A locking latch 1231 is provided at the top of the locking ring 123. The locking latch 1231 penetrates through the through hole 1211. The center of the arc path of the through hole 1211 is located on the rotation axis of the locking ring 123. A plurality of first teeth 1232 are provided along the outer periphery of the locking ring 123.

[0057] A plurality of second teeth 1241 are provided along the outer periphery of the locking gear 124. The locking gear 124 is rotatably disposed within the space between the bottom cover 122 and the support cover 121, and the second teeth 1241 mesh with the first teeth 1232.

[0058] As Figure 2 and Figure 7 shown, the locking handle 125 is rotatably disposed on the base housing 110. The main body portion is located outside the base housing 110, and the other portion is located inside the base housing 110 and is connected to the locking gear 124 to drive the locking gear 124 to rotate.

[0059] As Figure 7 and Figure 8 shown, the user rotates the locking handle 125 to drive the locking gear 124 to rotate. Through the transmission of the first teeth 1232 and the second teeth 1241, the locking gear 124 drives the locking latch 1231 on the locking ring 123 to rotate, realizing the locking or detachment of the locking latch 1231 from the card slot 2111 (see Figure 3 ), and further realizing the detachable connection between the cup body 200 and the base 100. The length of the through hole 1211 can ensure that the locking latch 1231 can achieve positioning and guiding between the locking position and the detachment position. The positioning post 1212 cooperates with the locking latch 1231. When the locking latch 1231 is in the detachment position, the positioning post 1212 supports the locking latch 1231 and also facilitates the positioning of the cup body 200.

[0060] As Figure 5 shown, the power source 130 includes a motor 131, a second connector 132, and an elastic pad 133. The main body of the motor 131 is disposed in the cavity 111 of the base housing 110 and is fixed on the fixing post 1214 (see Figure 8 ) in the locking component 120. The top end of its drive shaft 1311 extends out from the top of the base housing 110. The second connector 132 is coaxially fixed to the top end of the drive shaft 1311. The elastic pad 133 is sleeved outside the second connector 132. The second connector 132 is used to be plugged and matched with the first connector 265 in the cup body 100 to form a coupling, thereby transmitting the power of the motor 131 to the cup body 100. The elastic pad 133 can be made of rubber material and is clamped between the first connector 265 and the second connector 132 to reduce the noise generated during the power transmission process.

[0061] As Figure 6As shown, the power supply assembly 140 includes a first electrode 141, a mounting base 142, and a driver 143. The first electrode 141 is disposed on the mounting base 142. The mounting base 142 is movably connected to the support cover 121 and can approach or move away from the cup body 200. The driving unit 142 is used to drive the mounting base 142 to move, so as to contact or separate from the second electrode 240 in the cup body 200, and selectively supply power to the cup body 200.

[0062] The input panel is disposed on the outer surface of the base housing 110 to input control instructions.

[0063] As Figure 5 shown, the driving board 150 is disposed in the cavity 111 and is electrically connected to the power source 130 and the input panel respectively. It is used to receive the control instructions transmitted by the input panel and control the operation of the power source 130 according to the control instructions, that is, to control the start, stop, forward and reverse rotation of the motor 131, or to control the rotation speed of the motor 131. Please refer to Figure 6 together. The driving board 150 is also electrically connected to the driver 143 in the power supply assembly 140 (see Figure 6 ), and is used to control the operation of the driver 143 according to the control instructions, so as to control the power supply assembly 140 to supply power to or cut off power from the cup body 200.

[0064] Cup body 200:

[0065] Figure 9 is a sectional view of the cup body in the first embodiment of the cooking device of the present application.

[0066] As Figure 9 shown, the cup body 200 includes a container housing 210, a container 220, a heating plate 230, a second electrode 240, an operation assembly 250, and a transmission assembly 260.

[0067] The container housing 210 includes a housing main body 211, a second hollow column 212, and an outer cover 213.

[0068] A card slot 2111 is provided at the bottom of the housing main body 211, and is cooperated with the lock 1231 of the lock assembly 120 through the card slot 2111 (see Figure 3 ), and is detachably fixed to the top of the base 100. The housing main body 211 forms a cavity with an open top.

[0069] The outer cover 213 is detachably sealed at the top of the housing main body 211. Specifically, the outer cover 213 is snap-connected to the housing main body 211. Of course, a threaded connection can also be used instead.

[0070] The second hollow column 212 is specifically described in the part of the transmission assembly 260 below.

[0071] The container 220 is a rotating body, which is rotatably accommodated in the container shell 210 around its own axis and is rotatably connected to the container shell 210. The container shell 210 is isolated from the outside world to avoid accidental injuries during the rotation process. The container 220 and the container shell 210 are rotatably matched, and the weight of the container 220 is transferred to the container shell 210, which can prevent the weight from being transferred to the power source 130 and affecting the service life of the power source 130. The specific structure of the container 220 being rotatably matched with the container shell 210 is shown in the transmission assembly 260 section below.

[0072] like Figure 9 As shown, the container 220 includes a container body 221 , a first hollow column 222 and an inner cover 223 .

[0073] The container body 221 is a rotating body, forming a cavity 2211 with an opening at the upper end. The user can put food or slurry to be cooked through the opening, pour out the cooked slurry in the cavity 2211 through the opening, and clean the inner wall of the container body 221 through the opening. Grinding teeth 2212 are convexly provided on the bottom surface of the container body 221. The grinding teeth 2212 are used to cooperate with the operating component 250 to grind the food.

[0074] The first hollow column 222 protrudes downward from the bottom of the container body 221 and is integrally formed with the container body 221. In another embodiment, it can also be a split structure. The first hollow column 222 is coaxial with the axis of rotation of the container body 221 and is used to receive force to drive the container body 221 to rotate. A through hole is provided at the bottom of the container body 221, and the through hole connects the cavity 2211 and the space inside the first hollow column 222.

[0075] The inner cover 223 is detachably sealed on the opening at the top of the container body 221 , and a vent hole is provided at the center of the inner cover 223 so that hot air inside the container 220 can escape.

[0076] like Figure 9 As shown, the heating plate 230 is accommodated in the cavity formed by the shell body 211, attached to the outer wall surface of the bottom of the container body 221, and is used to generate heat after being powered on to heat the food in the container 220. The heating plate 230 is a rotating body and is coaxial with the container 220 to avoid affecting the rotation stability of the container 220.

[0077] like Figure 9 As shown, the second electrode 240 is accommodated in the cavity formed by the shell body 211 and fixed to the bottom of the heating plate 230, and is used to cooperate with the power supply component 140 to supply power to the heating plate 230. The second electrode 240 is a rotating body and is coaxial with the container 220 to avoid affecting the rotation stability of the container 220.

[0078] Specifically, Figure 4 andFigure 6 As shown, when the container 220 is not rotating, the driver 143 drives the mounting base 142 to rise, so that the first electrode 141 contacts the second electrode 240 and conducts, thus realizing power supply. After heating is completed, the driver 143 drives the mounting base 142 to descend, so that the first electrode 141 separates from the second electrode 240 and power supply stops. When grinding food, heating the food can save grinding time and improve processing efficiency. Since the second electrode 240 is a rotating body, no matter where the container 220 stops after rotation, it does not affect the contact between the first electrode 141 and the second electrode 240.

[0079] As Figure 9 shown, the operating assembly 250 is rotatably disposed in the cavity 2211 of the container body 221 to perform a crushing operation on food. In this embodiment, the operating assembly 250 includes a cutting tool 251 and a grinding tool 252. The cutting tool 251 is used for cutting food. The grinding tool 252 is used to cooperate with the grinding teeth 2212 to grind the cut food.

[0080] Figure 10 is Figure 9 an enlarged view of a partial view, which can more clearly show the structure at the transmission assembly.

[0081] As Figure 9 and Figure 10 shown, the transmission assembly 260 includes a rotating shaft 261 and a first one-way bearing 262. The rotating shaft 261 is an 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 can achieve rotational connection in one direction and lock in the reverse direction.

[0082] One end of the rotating shaft 261 is used to introduce power from the power source 130, and the other end is used to extend into the container 220 to connect the operating assembly 250.

[0083] In this embodiment, the other end (top end) of the rotating shaft 261 extends into the container 220 from the bottom of the container 220. Specifically, the rotating shaft 261 is coaxially inserted into the first hollow column 222. The bottom end of the rotating shaft 261 is connected to the power source 130 (see Figure 3 ), and rotates under the drive of the power source 130. The top end of the rotating shaft 261 extends into the cavity 2211 of the container body 221 through the through hole, and a sealing treatment is performed between the rotating shaft 261 and the container body 221.

[0084] Both the cutting tool 251 and the grinding tool 252 are arranged at the top end of the rotating shaft 261 and rotate driven by the rotating shaft 261. In other embodiments, the operating assembly 250 may also include a tool shaft (not shown in the figure). The cutting tool 251 and the grinding tool 252 are arranged on the tool shaft. The tool shaft is connected to the rotating shaft 261 and rotates following the rotating shaft 261.

[0085] The first one-way bearing 262 is configured to be connected to the container 220 and the rotating shaft 261. When the rotating shaft 261 rotates in one direction, it can drive the operating assembly 250 and the container 220 to rotate simultaneously. When the rotating shaft 261 rotates in the opposite direction of this direction, it only drives the operating assembly 250 to rotate.

[0086] Specifically, the inner ring of the first one-way bearing 262 is fixedly sleeved on the rotating shaft 261. The outer ring of the first one-way bearing 262 is embedded in the first hollow column 222. The inner and outer rings of the first one-way bearing 262 can be limited by keys. This limiting method is a prior art and will not be elaborated here. When the first one-way bearing 262 is in a rotatable 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.

[0087] In the following text, for the convenience of distinguishing the rotation directions of the rotating shaft 261, the following definitions are made: when the rotating shaft 261 rotates forward, the first one-way bearing 262 is in a rotatable connection state; when the rotating shaft 261 rotates reversely, the first one-way bearing 262 is in a locked state. Forward and reverse rotations only indicate that the rotating shaft 261 rotates in two opposite directions.

[0088] When the rotating shaft 261 rotates forward, the rotating shaft 261 only drives the operating assembly 250 to rotate to perform a crushing operation to process food into slurry. When the rotating shaft 261 rotates reversely, the rotating shaft 261 drives the operating assembly 250 and the container 220 to rotate simultaneously to perform a centrifugation operation on the slurry. By controlling the forward and reverse rotations of the rotating shaft 261, the cooking machine 1000 can selectively perform a crushing operation or a centrifugation operation.

[0089] To enable the operating assembly 250 and the container 220 to rotate respectively, one way is to drive the operating assembly 250 and the container 220 to rotate through two transmission parts respectively. When a crushing operation is required, only the operating assembly 250 is driven to rotate. When a centrifugation operation is required, only the container 220 is driven to rotate. At this time, two power sources need to be set. During the centrifugation operation, only the container 220 is driven to rotate, and the operating assembly 250 does not move. The operating assembly 250 rotates relative to the container 220, and the operating assembly 250 will disturb the slurry in the container 220, thereby affecting the centrifugation effect.

[0090] In this embodiment, the transmission assembly 260 is respectively connected to the container 220 and the operation assembly 250, and can selectively drive the container 220 and the operation assembly 250 to rotate respectively. It has a simple structure, small occupied space and low cost. In addition, during the centrifugation operation, the operation assembly 250 and the container 220 are relatively stationary, avoiding the operation assembly 250 from disturbing the slurry and ensuring the centrifugation effect.

[0091] As Figure 9 and Figure 10 shown, to prevent the container 220 from yawing during rotation and improve the stability of the centrifugation operation of the food processor 1000, the transmission assembly 260 further includes a first bi-directional bearing 263. Whether the rotating shaft 261 rotates forward or backward, the first bi-directional bearing 263 will not hinder the relative rotation of the rotating shaft 261 and the container 220. The first bi-directional bearing 263 can be a deep groove ball bearing. The inner ring of the first bi-directional bearing 263 is fixedly sleeved on the rotating shaft 261, and the outer ring of the first bi-directional bearing 263 is embedded in the first hollow column 222. The first bi-directional bearing 263 and the first one-way bearing 262 are coaxially arranged and axially spaced on the rotating shaft 261. In other embodiments, they can also be axially abutted against each other on the rotating shaft 261. Compared with axially abutting against each other, axially spacing can better prevent the container 220 from yawing during rotation.

[0092] Furthermore, as Figure 9 and Figure 10 shown, the transmission assembly 260 further includes a sleeve 264. The inner ring of the first bi-directional bearing 263 is non-rotatably sleeved on the rotating shaft 261 through a key, and its outer ring is non-rotatably embedded in the first hollow column 222 through a key. Similarly, the inner ring of the first one-way bearing 262 is non-rotatably sleeved on the rotating shaft 261 through a key, and its outer ring is non-rotatably embedded in the first hollow column 222 through a key. Axially, the outer ring of the first bi-directional bearing 263 abuts against the limiting surface 2221 of the first hollow column 222. The sleeve 264 is sleeved on the rotating shaft 261 and clamped between the inner rings of the first one-way bearing 262 and the first bi-directional bearing 263. A snap ring 265 clamped on 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 bi-directional bearing 263 axially on the rotating shaft 261. After removing the snap ring 265, the first one-way bearing 262, the sleeve 264 and the first bi-directional bearing 263 can be respectively removed from the rotating shaft 261.

[0093] By axially limiting the first one-way bearing 262 and the first bi-directional bearing 263 through the sleeve 264, the structure is simple and easy to disassemble and assemble.

[0094] As Figure 5 and Figure 10As shown, the transmission assembly 260 further includes a first connector 265. The first connector 265 is fixedly disposed at the end of the rotating shaft 261 to be pluggable and matched with the power source 130 at the end of the rotating shaft 261, so as to transmit the power of the power source 130.

[0095] The first connector 265 is detachably fixed to the bottom end of the rotating shaft 261. In other embodiments, the first connector 265 can also be an integral structure with the rotating shaft 261. Specifically, the first connector 265 is sleeve-shaped, and the opening faces the power source 130. The first connector 265 is coaxially arranged with the rotating shaft 261. The inner wall of the first connector 265 is provided with a plurality of ribs 2651 at intervals along the circumferential direction, and each rib 2651 extends along the axial direction of the rotating shaft 261. The shape of the second connector 132 in the power source 130 matches the cavity of the first connector 265, and the outer periphery of the second connector 132 is provided with a plurality of grooves (not visible in the figure), and the plurality of grooves are equal to and correspond to the plurality of ribs 2651 one by one, and each groove extends in the axial direction of the driving shaft 1311. When in use, the ribs 2651 are clamped in the corresponding grooves to transmit torque.

[0096] Since the rotating shaft 261 can be plugged in and out of the power source 130 , it is convenient to realize a detachable connection between the base 100 and the cup body 200 .

[0097] like Figure 9 As shown, during the crushing operation, especially when grinding food, the grinding teeth 2212 will be stressed. If the container 220 can rotate freely, it will be disadvantageous for grinding. Therefore, in this embodiment, during the crushing operation, the container 220 is fixed relative to the container shell 210; during the centrifugal operation, the container 220 can rotate relative to the container shell 210.

[0098] The specific structure of the rotational cooperation between the container 220 and the container shell 210 is described below:

[0099] like Figure 9 As shown, the second hollow column 212 protrudes upward from the bottom of the shell body 211 and is integrally formed with the shell body 211. In other embodiments, the second hollow column 212 and the shell body 211 may also be separate structures. The second hollow column 212 is coaxially disposed outside the first hollow column 222.

[0100] Please refer to Figure 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 connected to the container 220 and the container shell 210, and can allow the container 220 to rotate relative to the container shell 210 when the rotating shaft 261 rotates in one direction, and prevent the container 220 from rotating relative to the container shell 210 when the rotating shaft 261 rotates in the opposite direction of the direction.

[0101] The second one-way bearing 266 can achieve rotational connection in one direction and lock in the reverse direction.

[0102] Specifically, the inner ring of the second one-way bearing 266 is fixedly sleeved on the outer side of the first hollow column 222, and the outer ring of the second one-way bearing 266 is fixedly sleeved on the inner side of the second hollow column 212. The second one-way bearing 266 is coaxially arranged with the rotating shaft 261.

[0103] When the rotating shaft 261 rotates, one of the first one-way bearing 262 and the second one-way bearing 266 is in a rotational connection state, and the other is in a locked state.

[0104] When the food processor 1000 performs a 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 rotational connection state, and the rotating shaft 261 drives the operating assembly 250 to rotate;

[0105] When the food processor 1000 performs a centrifugal operation, the second one-way bearing 266 is in a rotational connection state, the container 220 can rotate relative to the container housing 210, the first one-way bearing 262 is in a locked state, and the rotating shaft 261 drives the container 220 to rotate.

[0106] To prevent the container 220 from wobbling when rotating relative to the container housing 210, as Figure 9 and Figure 10 shown, the transmission assembly 260 further includes a second double-direction bearing 267. The second double-direction bearing 267 is coaxially arranged with the second one-way bearing 266 and abuts against the second one-way bearing 266 in the axial direction of the second one-way bearing 266. In other embodiments, if there is enough space, the second double-direction bearing 267 and the second one-way bearing 266 can also be arranged at intervals. The inner ring of the second double-direction bearing 267 is fixedly sleeved on the outer side of the first hollow column 222, and the outer ring of the second double-direction bearing 267 is fixedly sleeved on the inner side of the second hollow column 212. Whether performing a crushing operation or a centrifugal operation, the second double-direction bearing 267 will not hinder the rotation of the container 220 relative to the container housing 210. The second double-direction bearing 267 can be a deep groove ball bearing, which is a prior art.

[0107] Beneficial effects of the first embodiment of the food processor:

[0108] The container is driven by a rotating shaft to rotate. The slurry in the container moves away from the center of the container under the action of centrifugal force and contacts the inner wall of the container. After centrifugation, the dregs in the slurry adhere to the inner wall of the container, and the slurry flows back to the bottom of the container, thereby separating the dregs from the slurry and reducing or even avoiding the filtration operation. In a usage scenario, when the rotation speed of the container reaches 500 revolutions per minute to 5000 revolutions per minute, the dregs in the slurry can adhere to the inner wall of the container. The rotation speed can be set according to the portion and type of food.

[0109] There can be various implementation manners for the first one-way rotating member, and the present application is not limited to the first one-way bearing 262. Figure 11 Another alternative implementation manner of the first one-way rotating member is shown. As Figure 11 shown, the first one-way rotating member includes an internal gear ring 10 and a pawl disk 20.

[0110] The internal gear ring 10 can be embedded in the first hollow column 222. The internal gear ring 10 and the first hollow column 222 can be of a split structure or an integral structure. The internal gear ring 10 is annular, and a plurality of teeth 11 are formed on its inner peripheral edge.

[0111] The pawl disk 20 can be fixedly sleeved on the rotating shaft 261. The pawl disk 20 is disk-shaped, and a plurality of pawls 30 are arranged at intervals on its outer peripheral edge. The pawls 30 are in elastic contact and cooperation with the internal gear ring 10.

[0112] When the pawl disk 20 rotates counterclockwise in Figure 11 , the end of the pawl 30 fits against the first surface 12 of the tooth 11 and moves relatively. The first surface 12 generates a radially inward acting force on the pawl 30 along the pawl disk 20, causing the pawl 30 to elastically deform and retract, and further enabling the pawl disk 20 to rotate unhindered. When the pawl disk 20 rotates clockwise in Figure 11 , the end of the pawl 30 abuts against the second surface 13 of the tooth 11. The second surface 13 generates a radially outward acting force on the pawl 30 along the pawl disk 20, causing the pawl 30 to elastically deform and expand, hindering the rotation of the pawl disk 20.

[0113] In this implementation manner, the rotating shaft 261 can only rotate counterclockwise in Figure 11 , which can replace the first one-way bearing 262. The first one-way rotating member in this implementation manner can also replace the second one-way bearing 266 in the above text.

[0114] In this embodiment, the rotating shaft and the power source are pluggable and cooperate with each other in contact for transmission. In other embodiments, a non-contact transmission method may also be adopted between the rotating shaft 261 and the power source 130. For example, magnetic drive coupling can be used for transmission. A magnetic drive coupling generally consists of two magnets, which are respectively arranged on the driving shaft and the driven shaft. By using the magnetic coupling principle, the transmission of force and torque between the driving shaft and the driven shaft can be realized without direct contact. The magnetic drive coupling is a prior art and will not be elaborated here.

[0115] In other embodiments, the outer cover may not be provided in the container housing. That is, the container housing only includes the housing body. When the cooking machine is in use, especially during centrifugal operation, the housing body protects the periphery of the container, which can reduce the risk of injury caused by the rotation of the container to a certain extent. Not providing the outer cover can reduce one opening operation. In addition, the hot air in the container can also escape more easily.

[0116] In other embodiments, the power source, the power supply component, the drive board, and the input panel in the base may also be arranged in the cup body, for example, on the container housing. The base only includes the base housing to support the cup body. The cup body uses its own power to heat the food and uses its own power to crush and / or centrifuge the food.

[0117] In this embodiment, the container is rotatably connected to the container housing, but the present application is not limited thereto. In other embodiments, the container may also be rotatably connected to the base. When the volume of the container is small, the container may also be only (unidirectionally) rotatably connected to the rotating shaft (neither rotatably connected to the container housing nor to the base).

[0118] (Embodiment 2)

[0119] In Embodiment 1, the second one-way rotating member is arranged at the bottom of the container and sleeved outside the first hollow column. In order to accommodate the first one-way rotating member, the outer diameter of the first hollow column is relatively large. This results in a relatively large size and weight of the second one-way rotating member, and thus a relatively large load on the power source. To reduce the weight of the second one-way rotating member, the cup body is improved in Embodiment 2.

[0120] Figure 12 It is a sectional view of the cup body in Embodiment 2 of the cooking machine of the present application.

[0121] As Figure 12 shown, the cup body 300 includes a container housing 310, a container 320, a heating plate (not shown in the figure), a second electrode (not shown in the figure), an operation component 350, and a transmission component 360.

[0122] The container housing 310 includes a housing body 311, a second hollow column 312, and an outer cover 313.

[0123] The outer shell main body 311 is detachably fixed to the top of the base through a card slot. The outer shell main body 311 forms a cavity with an open top end. The second hollow column 312 protrudes upward from the bottom of the outer shell main body 311 and is integrally formed with the outer shell main body 311.

[0124] The outer cover 313 includes an outer cover main body 3131 and a third hollow column 3132.

[0125] The outer cover main body 3131 detachably seals the top end of the outer shell main body 311. Specifically, the outer cover main body 3131 is snap-connected to the outer shell main body 311. The third hollow column 3132 protrudes downward from the central area of the outer cover main body 3131 and is integrally formed with the outer cover main body 3131. The third hollow column 3132 is coaxial with the second hollow column 312.

[0126] The container 320 includes a container main body 321, a first hollow column 322, and an inner cover 323.

[0127] The container main body 321 forms a cavity with an open top end. The container main body 321 is accommodated in the cavity of the outer shell main body 311. The container main body 321 is a rotating body.

[0128] The first hollow column 322 protrudes downward from the bottom of the container main body 321 and is integrally formed with the container main body 321. The first hollow column 322 is coaxial with the container main body 321 and is coaxially arranged inside the second hollow column 312 for rotational cooperation with the second hollow column 312.

[0129] The inner cover 323 includes an inner cover main body 3231 and a hollow shaft 3232.

[0130] The inner cover main body 3231 is embedded in the opening at the top end of the container main body 321 and is relatively fixed to the container main body 321 through friction. In other embodiments, a limiting structure may also be provided so that after the inner cover main body 3231 covers the opening at the top end of the container main body 321, it is non-rotatable relative to the container main body 321. The hollow shaft 3232 is fixed to the center of the inner cover main body 3231 and is coaxially arranged inside the third hollow column 3132. The hollow shaft 3232 communicates the cavity of the container 320 with the external environment. The hot air inside the container 320 can escape through the hollow shaft 3232.

[0131] 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.

[0132] The rotating shaft 361 is coaxially arranged in the first hollow column 322, with its top end inserted into the container body 321 to be connected to the operating component 350, and its bottom end fixedly connected to the first connector 365.

[0133] 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, if it is necessary to drive the container 320 to rotate, the power source needs to provide a large torque to the container 320 through the first one-way bearing 362. To meet the requirement of large torque, two first one-way bearings 362 are provided in this embodiment. In other embodiments, more first one-way bearings 362 can also be provided, and multiple first one-way bearings 362 are axially distributed on the rotating shaft 361. The more the number of the first one-way bearings 362, the smaller the torque transmitted by a single first one-way bearing 362. However, at the same time, the weight will also increase, which will increase the load of the power source. Therefore, comprehensive consideration should be given to reasonably determine the number of the first one-way bearings 362.

[0134] The inner ring of the first two-way 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 two-way bearing 363 and the two first one-way bearings 362 are axially arranged on the rotating shaft 361 and are in contact with each other.

[0135] The inner rings of the two third two-way bearings 368 are fixedly sleeved outside the first hollow column 322, and the outer rings are fixedly embedded in the second hollow column 312.

[0136] 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 column 3132.

[0137] The inner ring of the second two-way bearing 367 is fixedly sleeved on the hollow shaft 3232, and the outer ring is fixedly embedded in the third hollow column 3132.

[0138] When the rotating shaft 361 rotates, one of the first one-way bearing 362 and the second one-way bearing 366 is in a rotating connection state, and the other is in a locked state.

[0139] When the food processor performs a 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 rotating connection state, and the rotating shaft 361 drives the operating component 350 to rotate;

[0140] When the food processor performs a centrifugal operation, the second one-way bearing 366 is in a rotating connection state, the container 320 can rotate relative to the container housing 310, the first one-way bearing 362 is in a locked state, and the rotating shaft 361 drives the container 320 to rotate.

[0141] In this embodiment, the second one-way bearing 366 is sleeved outside the hollow shaft 3232, and the hollow shaft 3232 is used for ventilation and has an outer diameter smaller than that of the first hollow column 322. Therefore, compared with the first embodiment, a smaller specification of the second one-way bearing 366 can be selected in this embodiment. The second one-way bearing 366 with a smaller specification has a smaller weight, which can reduce the load on the power source.

[0142] Both the top and the bottom of the container 320 are rotatably connected to the container housing 310. Compared with the first embodiment (only the bottom is rotatably connected), during the centrifugation operation, the container 320 rotates more stably and is not prone to yaw.

[0143] By providing the hollow shaft 3232, the hot air in the container 320 can be better discharged. At the same time, combining the second one-way bearing 366 with the hollow shaft 3232 results in a simple structure. In addition, the outer cover 313 and the inner cover 323 are integrally connected (rotatable relative to each other), making the opening operation simpler. In the first embodiment, the cover needs to be opened twice, while in this embodiment, only one opening is required.

[0144] The remaining parts of this embodiment can refer to the first embodiment and will not be elaborated here.

[0145] The above are only the embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
