Detailed implementation manners

[0032] In order to enable those skilled in the art of the present technology to better understand the solution of the embodiment of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the embodiments of the present invention.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] In the related art, the methods of opening and closing the pot lid of a cooking device include manually opening and closing the pot lid or fully automatically opening and closing the pot lid. Manually opening and closing the pot lid requires the user to completely screw the pot lid to open or close it, which will make the user feel strenuous and inconvenient for the user to operate. The fully automatic opening and closing of the pot lid is achieved by setting a driving motor to automatically lock or unlock the pot lid. Although this method can facilitate the user to open or close the pot lid, in the power-off state, the driving motor cannot work, which will cause the pot lid to not be able to be normally opened or closed. Although some cooking devices are provided with an abnormal power-off unlocking device, due to the driving motor not being decoupled, a relatively large force is required to drive the driving motor to decouple, and then the pot lid is locked or unlocked through the abnormal power-off unlocking device, which is inconvenient for the user to operate.

[0035] Refer to Figure 1 , an embodiment of the present invention provides a cooking device 1000, and the cooking device 1000 can be a rice cooker, an electric cooking pot, an air oven, a griddle and other devices. The cooking device 1000 can be a flip-top device, an open-top device, etc.

[0036] Refer to Figure 1 and Figure 2 , in some embodiments, the cooking device 1000 includes a pot lid 200 and a pot lid opening and closing device 100, and the pot lid opening and closing device 100 is installed on the pot lid 200.

[0037] In this way, the cooking device 1000 can assist in opening and closing the pot lid 200 through the pot lid opening and closing device 100, which helps to facilitate the opening and closing of the pot lid 200 and is convenient for the user to operate.

[0038] Refer to Figures 2 to 6 , in some embodiments, the pot lid opening and closing device 100 includes a locking component 10, an electric drive component 13 and a manual unlocking component 14. The electric drive component 13 can move along the first direction Y, and when the electric drive component 13 is in the first position, it is coupled with the locking component 10, and when it is in the second position, it is decoupled from the locking component 10. The manual unlocking component 14 can drive the electric drive component 13 to move along the first direction Y, and when the manual unlocking component 14 drives the electric drive component 13 to move to the second position, the manual unlocking component 14 is coupled with the locking component 10. Wherein, the first direction Y can be the height direction of the pot lid opening and closing device 100.

[0039] In this way, when the power is normally on, the electric drive assembly 13 can be coupled with the latch assembly 10, so as to drive the latch assembly 10 to act in an electric drive manner, so that the latch assembly 10 is locked or unlocked, thereby opening or closing the pot lid 200; and in the power-off state, the electric drive assembly 13 can also be decoupled from the latch assembly 10 by operating the manual unlocking assembly 14, and the manual unlocking assembly 14 can manually drive the latch assembly 10 to act, so that the latch assembly 10 is locked or unlocked, thereby opening or closing the pot lid 200. The pot lid opening and closing device 100 can work normally under both power-on and power-off conditions, so that the pot lid opening and closing device 100 can be applied to different scenarios, which helps to better meet the user's usage requirements.

[0040] Exemplarily, as Figure 3 and Figure 4 shown, when the electric drive assembly 13 is in the first position, the manual unlocking assembly 14 is decoupled from the latch assembly 10, and the electric drive assembly 13 is coupled with the latch assembly 10 to drive the latch assembly 10 to act by electric drive; for another example, as Figure 5 and Figure 6 shown, when the electric drive assembly 13 is in the second position, the manual unlocking assembly 14 drives the electric drive assembly 13 to move away from the latch assembly 10 along the first direction Y, so that the electric drive assembly 13 is decoupled from the latch assembly 10, and the manual unlocking assembly 14 is coupled with the latch assembly 10 to drive the latch assembly 10 to act manually.

[0041] In some embodiments, the latch assembly 10 includes a driving member 11, the electric drive assembly 13 and the manual unlocking assembly 14 are respectively located on opposite sides of the driving member 11, and when the electric drive assembly 13 is in the first position, the electric drive assembly 13 is coupled with the driving member 11. When the manual unlocking assembly 14 drives the electric drive assembly 13 to move away from the driving member 11 along the first direction Y to the second position, the electric drive assembly 13 is decoupled from the driving member 11, and the manual unlocking assembly 14 is coupled with the driving member 11.

[0042] In this way, the electric drive assembly 13 can be coupled with the driving member 11, so that the electric drive assembly 13 can drive the driving member 11 to act electrically, so that the latch assembly 10 is locked or unlocked, thereby opening or closing the pot lid 200; or the electric drive assembly 13 can be decoupled from the driving member 11 by operating the manual unlocking assembly 14, and the manual unlocking assembly 14 can manually drive the driving member 11 to act, so that the latch assembly 10 is locked or unlocked, thereby opening or closing the pot lid 200.

[0043] Among them, the electric drive assembly 13 and the manual unlocking assembly 14 are respectively located on two opposite sides of the driving member 11, which means that the electric drive assembly 13, the driving member 11, and the manual unlocking assembly 14 are arranged in sequence along one direction, and the driving member 11 is located between the electric drive assembly 13 and the manual unlocking assembly 14. For example, the electric drive assembly 13, the driving member 11, and the manual unlocking assembly 14 are arranged in sequence along the first direction Y, and the driving member 11 is located between the electric drive assembly 13 and the manual unlocking assembly 14.

[0044] In this way, the electric drive assembly 13 or the manual unlocking assembly 14 can be selectively moved along the first direction Y towards the driving member 11, so that the electric drive assembly 13 or the manual unlocking assembly 14 is coupled with the driving member 11 to lock or unlock the latch assembly 10. This also helps to reasonably layout the positions of the electric drive assembly 13 and the manual unlocking assembly 14, and helps to reduce the interference between the electric drive assembly 13 and the manual unlocking assembly 14 when they are located on the same side of the driving member 11.

[0045] In some embodiments, the electric drive assembly 13 and the manual unlocking assembly 14 are located on the same side of the driving member 11, and when the electric drive assembly 13 is in the first position, the electric drive assembly 13 is coupled with the driving member 11. When the manual unlocking assembly 14 drives the electric drive assembly 13 to move away from the driving member 11 along the first direction Y to the second position, the electric drive assembly 13 is decoupled from the driving member 11, and the manual unlocking assembly 14 is coupled with the driving member 11.

[0046] In this way, the electric drive assembly 13 or the manual unlocking assembly 14 can be selectively moved along the first direction Y towards the driving member 11, so that the electric drive assembly 13 or the manual unlocking assembly 14 is coupled with the driving member 11 to lock or unlock the latch assembly 10. This also helps to conveniently arrange the electric drive assembly 13 and the manual unlocking assembly 14 from the same side of the driving member 11, and helps to improve the structural compactness of the pot lid opening and closing device 100.

[0047] Refer to Figure 4 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the drive shaft 132 of the electric drive assembly 13 passes through the driving member 11 and abuts against the manual unlocking assembly 14. When the electric drive assembly 13 is in the first position, the electric drive assembly 13 is adapted to drive the driving member 11 to rotate synchronously relative to the manual unlocking assembly 14; when the electric drive assembly 13 is in the second position, the manual unlocking assembly 14 is adapted to drive the driving member 11 to rotate synchronously relative to the electric drive assembly 13.

[0048] In this way, the way for the electric drive assembly 13 and the manual unlocking assembly 14 to achieve linkage is simple, which is convenient for the manual unlocking assembly 14 to drive the electric drive assembly 13. This also helps to simplify the structure of the pot lid opening and closing device 100 and is conducive to the manufacture of the pot lid opening and closing device 100.

[0049] In addition, the rotation of the electric drive assembly 13 driving the driving member 11 relative to the manual unlocking assembly 14 will not affect the manual unlocking assembly 14, and the rotation of the manual unlocking assembly 14 driving the driving member 11 relative to the electric drive assembly 13 will not affect the electric drive assembly 13 either. The rotation of the electric drive assembly 13 driving the driving member 11 and the rotation of the manual unlocking assembly 14 driving the driving member 11 do not interfere with each other, which helps to ensure that the pot lid opening and closing device 100 can achieve electric unlocking and manual unlocking, and also helps to reduce the energy consumption waste and device wear caused by the long-term operation of the devices due to the synchronous rotation of the electric drive assembly 13, the driving member 11 and the manual unlocking assembly 14.

[0050] Refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 In some embodiments, the electric drive assembly 13 includes a driving member 133 and a first elastic member 134. The driving member 133 is connected between the first elastic member 134 and the driving member 11. The elastic force of the first elastic member 134 is adapted to drive the driving member 133 to move along the first direction Y, so that the electric drive assembly 13 is in the first position. Wherein, the driving member 133 can be a motor, and the first elastic member 134 can be a spring.

[0051] In this way, the acting force of the user operating the manual unlocking assembly 14 can overcome the elastic force of the first elastic member 134, so that the electric drive assembly 13 is decoupled from the driving member 11. When the acting force applied to the manual unlocking assembly 14 disappears, for example, when the user releases the manual unlocking assembly 14, the elastic force of the first elastic member 134 enables the driving member 133 to move along the first direction Y, so that the electric drive assembly 13 is coupled with the driving member 11, without the need for the user to manually drive the driving member 133 to move, which helps to simplify the user's operation process. When the electric drive assembly 13 is coupled with the driving member 11, the elastic force of the first elastic member 134 also enables the driving member 133 to move along the first direction Y to abut the electric drive assembly 13 against the driving member 11, which helps to reduce the situation where the electric drive assembly 13 becomes loose from the driving member 11.

[0052] Refer to Figures 5 to 8 In some embodiments, the manual unlocking assembly 14 includes an unlocking member 142 and a second elastic member 143. The second elastic member 143 is connected between the unlocking member 142 and the driving member 11. The elastic force of the second elastic member 143 is adapted to drive the unlocking member 142 to move along the first direction Y. Wherein, the second elastic member 143 can be a spring.

[0053] In this way, the acting force of the user operating the unlocking member 142 can overcome the elastic force of the second elastic member 143, so that the manual unlocking assembly 14 is coupled to the driving member 11. When the acting force applied to the unlocking member 142 disappears, for example, when the user releases the unlocking member 142, the elastic force of the second elastic member 143 enables the unlocking member 142 to move along the first direction Y, so that the manual unlocking assembly 14 is decoupled from the driving member 11, without the need for the user to manually drive the unlocking member 142 to move, which helps to simplify the user operation process.

[0054] The first elastic member 134 and the second elastic member 143 provided in this application help to absorb the impact and vibration outside the pot lid opening and closing device 100, and reduce the damage to the sensitive electronic components and other mechanical components inside the pot lid opening and closing device 100. The acting force of the user operating the unlocking member 142 can overcome the elastic forces of the first elastic member 134 and the second elastic member 143 to decouple the driving member 133 from the driving member 11 and couple the unlocking member 142 to the driving member 11. When the acting force applied to the unlocking member 142 disappears, the elastic force of the first elastic member 134 can drive the driving member 133 to act, so that the driving member 133 is automatically coupled to the driving member 11, and the elastic force of the second elastic member 143 can drive the unlocking member 142 to act, so that the unlocking member 142 is coupled to the driving member 11.

[0055] In this way, after the user operates the unlocking member 142 to open or close the pot lid 200, the driving member 133 and the unlocking member 142 can be reset to appropriate working positions under the action of the first elastic member 134 and the second elastic member 143 respectively, without the need for the user to manually reset the driving member 133 and the unlocking member 142, which simplifies the user operation process.

[0056] Refer to Figure 2 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the driving member 11 is provided with a first engaging portion 111 and a second engaging portion 112 that face away from each other. A first engaging portion 131 is provided on one side of the electric drive assembly 13 facing the driving member 11, and the first engaging portion 131 is movably engaged with the first engaging portion 111 along the first direction Y. A second engaging portion 141 is provided on one side of the manual unlocking assembly 14 facing the driving member 11, and the second engaging portion 141 is movably engaged with the second engaging portion 112 along the first direction Y. When the electric drive assembly 13 is in the first position, the first engaging portion 131 is engaged with the first engaging portion 111. When the electric drive assembly 13 is in the second position, the first engaging portion 131 disengages from the first engaging portion 111, and the second engaging portion 141 is engaged with the second engaging portion 112.

[0057] In this way, the way the electric drive assembly 13 and the manual unlocking assembly 14 are snap-connected to the driving member 11 is simple, which helps to facilitate the manufacture of the pot lid opening and closing device 100. The user can drive the electric drive assembly 13 to be decoupled from the driving member 11 by operating the manual unlocking assembly 14 to move along the first direction Y towards the driving member 11, and couple the manual unlocking assembly 14 to the driving member 11. At this time, the first snap-connecting portion 131 is disengaged from the first engaging portion 111, and the second snap-connecting portion 141 is snap-connected to the second engaging portion 112. Thus, by operating the manual unlocking assembly 14 to manually drive the driving member 11 to act, the locking assembly 10 can be locked or unlocked, so as to open or close the pot lid 200.

[0058] Exemplarily, as Figure 4 shown, when the pot lid opening and closing device 100 is powered on and working, the electric drive assembly 13 is powered on and working, the first snap-connecting portion 131 is snap-connected to the first engaging portion 111, and the electric drive assembly 13 electrically drives the driving member 11 to act, so as to lock or unlock the locking assembly 10, thus opening or closing the pot lid 200. For example, the electric drive assembly 13 drives the driving member 11 to rotate, so as to lock or unlock the locking assembly 10, thus opening or closing the pot lid 200, without the user manually screwing the pot lid 200, which is convenient for the user to open and close the pot lid 200.

[0059] Again, for example, as Figure 6 shown, when the pot lid opening and closing device 100 is powered off and working, the electric drive assembly 13 stops working. The user can operate the manual unlocking assembly 14, for example, pressing the manual unlocking assembly 14, so that the manual unlocking assembly 14 moves along the first direction Y towards the driving member 11. The manual unlocking assembly 14 drives the driving member 11 to move through the drive shaft 132, so that the driving member 11 moves away from the driving member 11 along the first direction Y, so as to disengage the first snap-connecting portion 131 from the first engaging portion 111. The way the electric drive assembly 13 is decoupled from the driving member 11 is simple and convenient for the user to operate. The manual unlocking assembly 14 moving along the first direction Y towards the driving member 11 also couples the manual unlocking assembly 14 to the locking assembly 10. At this time, the second snap-connecting portion 141 is snap-connected to the second engaging portion 112. The user can manually drive the driving member 11 to rotate by rotating the manual unlocking assembly 14, so as to lock or unlock the locking assembly 10, thus opening or closing the pot lid 200. The way the manual unlocking assembly 14 decouples the electric drive assembly 13 and drives the driving member 11 to act in a linked manner is simple, which is convenient for the user to open and close the pot lid 200.

[0060] In this way, the pot lid opening and closing device 100 can work normally in both the powered-on and powered-off states, so that the pot lid opening and closing device 100 can be applied to different scenarios, which helps to better meet the user's usage requirements.

[0061] Wherein, the snap connection between the first engaging portion 111 and the first snap-connecting portion 131 can adopt the cooperation of a convex block and a slot.

[0062] Exemplarily, the first engaging portion 111 may be a protrusion, which is located on the surface of the active component 11 facing the driving main component, and the first engaging portion 131 may be a slot, which is located on the surface of the driving main component facing the active component 11, and the protrusion is engaged in the slot to achieve the engagement between the first engaging portion 111 and the first engaging portion 131.

[0063] For another example, the first engaging portion 111 may be a slot located on the surface of the active component 11 facing the driving component, and the first engaging portion 131 may be a protrusion located on the surface of the driving component facing the active component 11, and the slot and the protrusion may be connected to each other to realize the engagement between the first engaging portion 111 and the first engaging portion 131.

[0064] In other embodiments, the first engaging portion 111 and the first engaging portion 131 may be engaged with each other in other ways, which may be specifically configured according to actual conditions.

[0065] The second engaging portion 112 and the second engaging portion 141 may be engaged in the same manner as the first engaging portion 111 and the first engaging portion 131, so as to simplify the structure of the pot cover opening and closing device 100 and facilitate manufacturing; the second engaging portion 112 and the second engaging portion 141 may also be engaged in a manner different from the first engaging portion 111 and the first engaging portion 131, and the specific arrangement may be made according to actual conditions.

[0066] In some embodiments, the first clamping portion 131 is chamfered, or the first clamping portion 131 is rounded. The second clamping portion 141 is chamfered, or the second clamping portion 141 is rounded.

[0067] In this way, it helps to facilitate the connection and separation of the first clamping portion 131 and the first clamping portion 111, helps to improve the connection efficiency and separation efficiency of the first clamping portion 131 and the first clamping portion 111, and also helps to facilitate the connection and separation of the second clamping portion 141 and the second clamping portion 112, helps to improve the connection efficiency and separation efficiency of the second clamping portion 141 and the second clamping portion 112.

[0068] In some embodiments, the locking assembly 10 also includes a driven member 12, which is transmission-connected to the driving member 11. The driving member 11 includes a driving tooth portion 113. The driving tooth portion 113 and the first engaging portion 111 and the second engaging portion 112 are respectively located on different sides of the driving member 11. The driven member 12 includes a driven tooth portion 121, which is meshed with the driving tooth portion 113.

[0069] In this way, the driving member 11 and the driven member 12 adopt a gear transmission form, which helps to simplify the transmission method between the driving member 11 and the driven member 12, is convenient for manufacturing, and also helps to improve the compactness of the structure between the driving member 11 and the driven member 12, and helps to reduce the space occupied by the pot lid opening and closing device 100 of the driving member 11 and the driven member 12.

[0070] Among them, the cooking device 1000 may further include a pot body 300, and the pot lid 200 is installed on the pot body 300. The pot lid 200 may be provided with a locking portion, and the pot body 300 may be provided with a locking and mating portion that cooperates with the locking portion. The pot lid opening and closing device 100 may drive the driven member 12 to move so that the driven member rotates to a suitable position, so that the locking portion can selectively connect or separate from the locking and mating portion, thereby realizing the locking or unlocking of the pot lid 200.

[0071] Refer to Figure 7 and Figure 8 In some embodiments, the first engaging portion 111 includes a plurality of first engaging sub-portions 1111, and the plurality of first engaging sub-portions 1111 are spaced apart. The first engaging portion 131 includes a plurality of first engaging sub-portions 1311, and the plurality of first engaging sub-portions 1311 are spaced apart around the driving shaft 132. When the first engaging portion 131 is engaged with the first engaging portion 111, the plurality of first engaging sub-portions 1111 are engaged with the plurality of first engaging sub-portions 1311 one by one.

[0072] In this way, the plurality of first engaging sub-portions 1111 and the plurality of first engaging sub-portions 1311 help to increase the contact area between the electric drive assembly 13 and the driving member 11, help to increase the force transmission efficiency, help to improve the stability of the electric drive assembly 13 driving the driving member 11 to move, and also help the electric drive assembly 13 and the driving member 11 to distribute the load more evenly, help to reduce the stress concentration of a single first engaging sub-portion 1111 and a single first engaging sub-portion 1311, and help to reduce the wear rate of a single first engaging sub-portion 1111 and a single first engaging sub-portion 1311, and extend the service life.

[0073] In addition, when a first engaging sub-portion 1111 or a first engaging sub-portion 1311 is worn or damaged, the other first engaging sub-portions 1111 and first engaging sub-portions 1311 can still continue to work, which helps to ensure the normal operation of the pot lid opening and closing device 100 and helps to improve the reliability of the pot lid opening and closing device 100.

[0074] Among them, the plurality means two or more. For example, the first engaging portion 111 includes two, three, four, five, six or other numbers of first engaging sub-portions 1111, and the number of the first engaging sub-portions 1311 is the same as the number of the first engaging sub-portions 1111 to ensure that the plurality of first engaging sub-portions 1111 are engaged with the plurality of first engaging sub-portions 1311 one by one.

[0075] In some embodiments, the second engaging portion 112 includes a plurality of second engaging sub - portions 1121 which are spaced apart. The second engaging sub - portions 1121 are distributed at intervals. The second engaging part 141 includes a plurality of second engaging sub - parts 1411 which are spaced apart around the driving shaft 132. When the second engaging part 141 is engaged with the second engaging portion 112, the plurality of second engaging sub - portions 1121 are engaged with the plurality of second engaging sub - parts 1411 one by one.

[0076] Thus, the plurality of second engaging sub - portions 1121 and the plurality of second engaging sub - parts 1411 help to increase the contact area between the manual unlocking assembly 14 and the driving member 11, help to increase the force transmission efficiency, help to improve the stability of the driving member 11 when the manual unlocking assembly 14 drives it to act, also help the manual unlocking assembly 14 and the driving member 11 to distribute the load more evenly, help to reduce the stress concentration on a single second engaging sub - portion 1121 and a single second engaging sub - part 1411, help to reduce the wear rate of a single second engaging sub - portion 1121 and a single second engaging sub - part 1411, and extend the service life.

[0077] In addition, when a second engaging sub - portion 1121 or a second engaging sub - part 1411 is worn or damaged, the other second engaging sub - portions 1121 and second engaging sub - parts 1411 can still continue to work, which helps to ensure the normal operation of the pot lid opening and closing device 100 and helps to improve the reliability of the pot lid opening and closing device 100.

[0078] Refer back to Figure 1 and Figure 2 In some embodiments, at least a part of the manual unlocking assembly 14 is exposed on the outer surface of the pot lid 200. For example, the unlocking member 142 is at least partially exposed on the outer surface of the pot lid 200.

[0079] Thus, the user can directly operate the exposed part of the manual unlocking assembly 14 without performing operations such as opening the lid to operate the manual unlocking assembly 14, which helps to facilitate the user's operation of the manual unlocking assembly 14 and also helps to improve the efficiency of the user in opening or closing the pot lid 200.

[0080] Refer to Figure 2 、 Figure 5 and Figure 9 In some embodiments, the pot lid 200 includes a lid body main body 210. The lid body main body 210 is provided with a limiting portion 211. The side of the driven member 12 away from the driving member 11 is rotatably connected to the limiting portion 211. The action of the driving member 11 is adapted to drive the driven member 12 to rotate around the central axis of the limiting portion 211.

[0081] In this way, the limiting portion 211 can limit the movement of the driven member 12 along the first direction Y, which helps to improve the stability of the connection between the driven member 12 and the cover body 210, helps to reduce the situation where the driven member 12 detaches from the cover body 210, helps to ensure the normal operation of the driven member 12, also helps to position the installation position of the driven member 12 and the cover body 210, helps to improve the accuracy of the installation position of the driven member 12 and the cover body 210, and helps to improve the efficiency of installing the driven member 12 on the cover body 210.

[0082] In some embodiments, the cover body 210 is further provided with a pressing portion 212. The pressing portion 212 and the limiting portion 211 are spaced apart. The driven member 12 is provided with an extending portion 122. The extending portion 122 rotatably abuts against the pressing portion 212, and the extending portion 122 is located between the pressing portion 212 and the inner wall of the cover body 210.

[0083] In this way, the pressing portion 212 and the limiting portion 211 can jointly limit the movement of the driven member 12 along the first direction Y, which helps to better improve the stability of the connection between the driven member 12 and the cover body 210, helps to better reduce the situation where the driven member 12 detaches from the cover body 210, and the pressing portion 212 can provide a supporting force for the extending portion 122, which helps to reduce the shaking when the driven member 12 rotates relative to the cover body 210 and helps to improve the stability of the rotation of the driven member 12 relative to the cover body 210.

[0084] In some embodiments, the pot lid 200 further includes a rotating cover body 220. The end of the cover body 210 is provided with a first guiding and sliding portion 213. The driven member 12 is provided with a first mating portion 123. The first mating portion 123 passes through the first guiding and sliding portion 213 and is connected to the rotating cover body 220. The first mating portion 123 slides in the first guiding and sliding portion 213 and is adapted to drive the rotating cover body 220 to rotate relative to the cover body 210.

[0085] In this way, the first guiding and sliding portion 213 can guide the rotation path of the driven member 12 relative to the cover body 210 by slidingly connecting with the first mating portion 123, and then drive the rotating cover body 220 to rotate relative to the cover, so that the rotating cover body 220 can rotate to a suitable position to open or close the pot lid 200, which helps to reduce the situation where the first mating portion 123 deviates from the rotation path, and also helps to reduce the frictional force during the rotation between the driven member 12, the rotating cover body 220 and the cover body 210, and helps to facilitate the user to operate the unlocking member 142 to drive the driven member 12 and the rotating cover body 220 to move.

[0086] In addition, the first guiding and sliding part 213 can provide a supporting force for the first mating part 123, which helps to reduce the wobbling when the first mating part 123 rotates relative to the cover body 210, helps to improve the stability of the rotation of the driven part 12 and the rotating cover 220 relative to the cover body 210, helps to reduce the wobbling when the driven part 12 and the rotating cover 220 rotate relative to the cover body 210, and also helps to reduce the frictional force during the rotation between the driven part 12, the rotating cover 220 and the cover body 210, which helps to facilitate the user to operate the unlocking part 142 to drive the driven part 12 and the rotating cover 220 to act.

[0087] Among them, the sliding connection between the first mating part 123 and the first guiding and sliding part 213 can adopt the cooperation of a connecting part and a sliding groove.

[0088] Exemplarily, the first mating part 123 can be a connecting part such as a screw. The screw is located on the surface of the driven part 12 facing the cover body 210. The first guiding and sliding part 213 can be a sliding groove, which is located on the surface of the cover body 210 facing the driven part 12. The rod part of the screw penetrates through the sliding groove and is connected to the rotating cover 220. The screw slides in the sliding groove to realize the sliding connection between the first mating part 123 and the first guiding and sliding part 213.

[0089] Also, for example, the sliding connection between the first mating part 123 and the first guiding and sliding part 213 can also adopt the cooperation of a slider and a slide rail.

[0090] Exemplarily, the first mating part 123 can be a slider, which is located on the surface of the driven part 12 facing the cover body 210. The first guiding and sliding part 213 can be a slide rail, which is located on the surface of the cover body 210 facing the driven part 12. The slider slides in the slide rail to realize the sliding connection between the first mating part 123 and the first guiding and sliding part 213.

[0091] In other embodiments, the sliding connection between the first mating part 123 and the first guiding and sliding part 213 can also adopt other methods, which can be specifically set according to the actual situation.

[0092] In some embodiments, a second guiding and sliding part 214 is further provided at the end of the cover body 210, and the driven part 12 is provided with a second mating part 124. The second guiding and sliding part 214 slides in the second mating part 124.

[0093] In this way, the first guiding and sliding part 213 and the second guiding and sliding part 214 can jointly guide the rotation paths of the driven part 12 and the rotating cover 220, which helps to more precisely guide the rotation paths of the driven part 12 and the rotating cover 220, and also helps to better support and fix the driven part 12 and the rotating cover 220, helps to reduce the inclination or offset problems caused by a single guiding and sliding part, and helps to improve the smoothness of the rotation of the driven part 12 and the rotating cover 220.

[0094] In addition, when a relatively large acting force is applied to the follower 12, the first sliding guide portion 213 and the second sliding guide portion 214 help to disperse the acting force received by a single sliding guide portion, which helps to extend the service life of a single sliding guide portion.

[0095] Among them, the sliding connection between the second mating portion 124 and the second sliding guide portion 214 can adopt the cooperation of a slider and a slide rail. For example, the second mating portion 124 is a slider, and the second sliding guide portion 214 is a slide rail, and the slider slides in the slide rail to achieve the sliding connection between the second mating portion 124 and the second sliding guide portion 214; or for another example, the second mating portion 124 is a slide rail, and the second sliding guide portion 214 is a slider, and the slider slides in the slide rail, which can also achieve the sliding connection between the second mating portion 124 and the second sliding guide portion 214.

[0096] In other embodiments, the sliding connection between the second mating portion 124 and the second sliding guide portion 214 can also adopt other methods, which can be specifically set according to the actual situation.

[0097] In summary, for the pot lid opening and closing device 100 and the cooking device 1000 provided by the embodiments of the present invention, the electric drive assembly 13 of the pot lid opening and closing device 100 can move along the first direction Y, and when the electric drive assembly 13 is in the first position, it is coupled to the locking component 10, and when it is in the second position, it is decoupled from the locking component 10.
