Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a cooking equipment. Background Art

[0002] In the related art, the transmission structure on the cooking device can transmit power to the target mechanism through rotation, so as to realize functions such as opening and closing the cover, locking and unlocking the inner pot, etc. through the target mechanism.

[0003] However, during the high-temperature cooking process, the transmission structure will inevitably produce thermal deformation, which will affect the matching accuracy of the transmission structure and cause the transmission structure to become stuck, disconnected, and other problems, resulting in technical problems such as poor transmission reliability and high failure rate in the cooking equipment.

[0004] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, the utility model proposes a cooking device.

[0007] In view of this, in the cooking device defined in the present invention, the cooking device includes: a main body; a shaft body, which is arranged on the main body, and the shaft body includes a limiting portion; a first transmission component, which is connected to the shaft body and can rotate around the axis of the shaft body; a second transmission component, which is connected to the first transmission component; wherein, along the axial direction of the shaft body, the first transmission component is clamped between the limiting portion and the second transmission component.

[0008] The cooking device defined in the present application includes a body, which is the main frame structure of the cooking device and is used to position, support and protect other working structures on the cooking device, wherein a cooking cavity is formed in the body, and ingredients are cooked into finished food in the cooking cavity.

[0009] The cooking device also includes a shaft, a first transmission component and a second transmission component. Specifically, the shaft is arranged on the main body, the first transmission component is connected to the shaft, the first transmission component can rotate relative to the shaft, and the shaft can provide radial positioning for the first transmission component. The second transmission component is connected to the first transmission component, and the rotating first transmission component can drive the second transmission component to move through contact to achieve power transmission. The second transmission component can be directly connected to the functional component, and can also be connected to other transmission components. When power is transmitted to the functional component, the functional component realizes the corresponding function of the cooking device through movement.

[0010] For example, the functional component locks the inner pot in the body to the cover in the body through movement, or the functional component locks the pot body and the cover in the body together through movement, or the functional component automatically pops the engaged cover off the pot body through movement. In this regard, the technical solution does not impose a rigid limit on the specific use of power transmission, and it is sufficient to meet the need to transmit power through the first transmission component and the second transmission component.

[0011] The shaft body proposed in the present application is provided with a limiting portion, and the limiting portion cooperates with the second transmission component to axially position the first transmission component. Specifically, in the axial direction of the shaft body, the limiting portion is located on the first side of the first transmission component, and the second transmission component is located on the opposite side of the limiting portion. The limiting portions and the second transmission components distributed on both sides can clamp the first transmission component between the two. Among them, considering that the thermal deformation of the structure cannot be avoided, the matching accuracy of the transmission structure is related to the length of its own dimension chain. The longer the dimension chain of the transmission matching is, the greater the amplitude of the thermal deformation is, and the greater the impact on the corresponding matching accuracy is. In this regard, the first transmission component rotating in the transmission process has a smaller size in the axial direction. In the axial direction, the limiting portions and the second transmission components respectively located on both sides of the first transmission component are used to clamp and position the first transmission component, which can reduce the length of the dimension chain of the shaft body, the first transmission component and the second transmission component, thereby reducing the thermal deformation amount and the influence of thermal deformation on the transmission matching accuracy, thereby solving the technical problems of large thermal deformation influence of the transmission structure, poor transmission reliability and high failure rate existing in the related art.

[0012] On the other hand, the clamping and positioning structure of the limiting part and the second transmission part can also reduce the axial misalignment space of the first transmission part, prevent the first transmission part from being separated from the shaft body, and ensure that the first transmission part can transmit power to the second transmission part. It can be seen that by clamping the first transmission part through the limiting part on the shaft body and the second transmission part, the first transmission part can be axially positioned with the help of the inherent shaft body and the second transmission part without adding a positioning structure.

[0013] On the other hand, the processing difficulty and production cost of the cooking equipment can be reduced on the basis of meeting the axial limit requirements, thereby achieving the technical effects of improving the structural stability and reliability of the cooking equipment, improving the transmission accuracy of the cooking equipment, and reducing the transmission failure rate of the cooking equipment.

[0014] Specifically, the limiting portion may be a limiting step provided on the shaft body, and the limiting step may block the first transmission component at the first side of the first transmission component.

[0015] In addition, the cooking device provided by the present invention may also have the following additional technical features:

[0016] In some technical solutions of the present utility model, optionally, the first transmission component includes a gear, and the gear is sleeved on the shaft; the second transmission component includes a rack, and the rack is meshed with the gear.

[0017] In this technical solution, the first transmission component includes a gear, and the second transmission component includes a rack. The gear meshes with the rack, and the rotating gear can drive the rack to move through meshing to achieve power transmission. The gear is sleeved on the rotating shaft, and the rotating shaft can provide radial positioning for the gear to ensure the meshing accuracy of the gear and the rack in the radial direction. The limiting part and the partial area on the rack can clamp the gear in the axial direction of the gear to ensure the meshing accuracy of the gear and the rack in the axial direction, ensure that the gear can work in the predetermined position, and avoid transmission failure caused by gear misalignment.

[0018] Gears and racks have the advantage of low transmission precision. Choosing gears and racks to transmit power can ensure the movement precision of functional components and ensure the effective execution of corresponding functions. At the same time, gears and racks also have the advantage of low transmission noise, which is conducive to reducing the working noise of cooking equipment.

[0019] In some technical solutions of the present utility model, optionally, the gear includes a first tooth portion, the rack includes a second tooth portion, the first tooth portion and the second tooth portion are meshed, and the first transmission component also includes: a boss, which is provided on the gear; along the axial direction of the shaft body, the limiting portion is located on the first side of the boss, and is opposite to the boss and / or the gear, and the second tooth portion is located on the second side of the boss, and is opposite to the boss.

[0020] In this technical solution, the gear is provided with a first tooth portion, the rack is provided with a second tooth portion adapted to the first tooth portion, and the gear and the rack are meshed through the first tooth portion and the second tooth portion.

[0021] On this basis, the first transmission component further includes a boss, which is arranged on the gear and located on the first side of the gear, the surface of the boss facing the limiting portion is the first surface, and the surface of the boss facing the rack is the second surface. After the first transmission component and the second transmission component are assembled, the boss is between the second tooth portion and the limiting portion, the limiting portion can provide a block to the first surface, and the second tooth portion can provide a block to the second surface, thereby achieving axial positioning of the gear and preventing the gear from being misplaced or even falling off the shaft.

[0022] By providing the boss, the axial movement of the gear can be limited by the second tooth portion without affecting the meshing relationship between the gear and the rack. At the same time, the structural complexity is low, and the boss can be integrally formed on the gear, which is conducive to reducing the cost of the cooking device and can provide convenient conditions for the miniaturization and lightweight design of the cooking device.

[0023] In some technical solutions of the present utility model, optionally, in the axial direction of the shaft body, the distance between the second tooth portion and the boss is greater than or equal to 0.2 mm.

[0024] In this technical solution, in the axial direction of the shaft body, the distance between the second tooth portion and the boss is L1, where L1 needs to be greater than or equal to 0.2 mm, that is, there needs to be enough clearance between the second tooth portion and the boss.

[0025] By setting a gap L1 between the second tooth portion and the boss, on the one hand, interference between the second tooth portion and the boss can be avoided, the transmission resistance between the gear and the rack can be reduced, and the possibility of the gear and the rack being stuck can be reduced. On the other hand, the gap L1 can leave enough axial displacement margin for the gear to prevent the moving gear from pushing the rack away from the predetermined position. This can achieve the technical effect of improving the transmission reliability and transmission accuracy of the gear and the rack, and improving the axial positioning stability of the gear.

[0026] In some technical solutions of the present invention, optionally, in the axial direction of the shaft body, the height of the first tooth portion is a first height; in the axial direction of the shaft body, the distance between the second tooth portion and the boss is less than or equal to two-thirds of the first height.

[0027] In this technical solution, in the axial direction of the shaft body, the height of the first tooth portion is a first height H. Correspondingly, in the axial direction of the shaft body, the distance between the second tooth portion and the boss is L1. Wherein, L1 and H satisfy the following relationship:

[0028] L1≤2÷3×H;

[0029] By limiting the above-mentioned dimensional relationship, it is possible to ensure that there is sufficient engagement depth between the first tooth portion and the second tooth portion, thereby preventing the first tooth portion on the gear from separating from the second tooth portion during movement, reducing the possibility of disconnection between the gear and the rack, and thereby achieving the technical effect of improving the transmission reliability of the gear and rack and reducing the failure rate of the cooking equipment.

[0030] In some technical solutions of the present invention, optionally, in the radial direction of the gear, the length of the overlapping area between the second tooth portion and the boss is greater than or equal to 2 mm.

[0031] In this technical solution, in the radial direction of the gear and the rack, the length of the overlap area between the second tooth portion and the boss is L2, and L2 must be greater than or equal to 2 mm. Among them, the area on the second tooth portion that overlaps with the boss in the radial direction can provide a barrier to the boss. By limiting the length of the overlap area L2 to be greater than or equal to 2 mm, it can be ensured that the second tooth portion can effectively block the movement of the boss, reducing the possibility of the boss knocking off the second tooth portion, thereby achieving the technical effect of improving the transmission reliability of the gear and rack and reducing the failure rate of the cooking equipment.

[0032] In some technical solutions of the present utility model, optionally, the boss is annular, and the boss and the gear share a common axis.

[0033] In this technical solution, the boss is annular, and the annular boss can ensure that when the gear rotates to any angle, the rack can provide axial limitation for the boss to avoid the occurrence of a limiting dead angle.

[0034] At the same time, the annular boss also has an anti-fool function, which can reduce the possibility of reverse installation of the gear.

[0035] Specifically, when the working stroke of the gear is less than 360°, the boss can also be semi-annular, and the specific orbiting angle is adapted to the working of the gear.

[0036] In some technical schemes of the utility model, optionally, the main body includes: a pot body; an inner pot, which is arranged in the pot body; a cover body, which is connected to the pot body, and the cover body is used to cover the inner pot; the cooking device also includes: a locking assembly, which is arranged on the cover body and connected to the second transmission component, and the locking assembly is used to lock the inner pot and / or the cover body.

[0037] In this technical solution, the main body includes a pot body, an inner pot and a cover body. The inner pot is embedded in the pot body. The pot body is used to position, support and protect the inner pot. A cooking cavity is formed in the inner pot. The food is cooked into finished food in the inner pot. The cover body is connected to the pot body and can move relative to the pot body. When the cover body is in the open state, the cover body avoids the opening of the inner pot. At this time, the user can put in the food or take out the finished food, and the inner pot can also be removed for cleaning. When the cover body is in the closed state, the cover body covers the opening of the inner pot.

[0038] On this basis, the cooking device further includes a locking component, which corresponds to the functional component in the aforementioned content, and specifically includes a first locking component and a second locking component.

[0039] The first locking assembly is disposed on the cover body, and the first locking assembly cooperates with the inner pot. Specifically, the first locking assembly includes a first posture and a second posture. When the cover body is closed and the first locking assembly is in the first posture, the first locking assembly can be locked with the inner pot in the pot body to lock the inner pot under the cover body, thereby creating a closed cooking environment in the inner pot. In this case, the air pressure value in the inner pot can be increased by heating the inner pot to achieve a high-pressure cooking function. Correspondingly, when the first locking assembly is in the second posture, the first locking assembly releases the lock on the inner pot, and the opening of the inner pot can be exposed by opening the cover body.

[0040] The second locking assembly is arranged on the pot body and / or the lid body, and the second locking assembly includes a third posture and a fourth posture. When the lid body is closed and the second locking assembly is in the third posture, the second locking assembly can lock the inner pot and the lid body together to ensure that the lid body can cover the inner pot, forming a closed environment in the inner pot, and facilitating pressure increase. When the lid body is closed and the second locking assembly is in the fourth posture, the second locking assembly releases the locking relationship between the inner pot and the lid body, and the lid body can be opened at this time to expose the opening of the inner pot.

[0041] In some technical solutions of the present invention, optionally, the cooking device further includes: a driving component, which is arranged on the cover body, and the driving component drives the first transmission component to rotate through the shaft.

[0042] In this technical solution, the cooking device further includes a driving component, which is disposed on the cover body and connected to the shaft body. The driving component can drive the gear to rotate by driving the shaft body.

[0043] Specifically, a knob may be selected as the driving component, and the user may rotate the gear and the rack by rotating the knob.

[0044] A motor can also be selected as a driving component, and the motor drives the gear and rack to rotate by forward and reverse rotation.

[0045] In some technical solutions of the present invention, optionally, the cooking device is: an electric rice cooker, a pressure cooker or an electric stew pot.

DETAILED DESCRIPTION

[0060] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0062] Refer to the following Figures 1 to 10 A cooking device according to some embodiments of the present invention is described.

[0063] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of the utility model proposes a cooking device 100, including: a main body 110; a shaft body 120, which is arranged on the main body 110, and the shaft body 120 includes a limiting portion 1202; a first transmission component 130, which is connected to the shaft body 120 and can rotate around the axis of the shaft body 120; a second transmission component 140, which is connected to the first transmission component 130; wherein, along the axial direction of the shaft body 120, the first transmission component 130 is clamped between the limiting portion 1202 and the second transmission component 140.

[0064] Figure 4 In FIG. 1 , the dotted line b shows the axial direction of the shaft body 120 .

[0065] The cooking device 100 defined in the present application includes a body 110, which is the main frame structure of the cooking device 100. The body 110 is used to position, support and protect other working structures on the cooking device 100, wherein a cooking cavity is formed in the body 110, and ingredients are cooked into finished food in the cooking cavity.

[0066] The cooking device 100 further includes a shaft 120, a first transmission component 130 and a second transmission component 140. Specifically, the shaft 120 is disposed on the body 110, the first transmission component 130 is connected to the shaft 120, the first transmission component 130 can rotate relative to the shaft 120, and the shaft 120 can provide radial positioning for the first transmission component 130. The second transmission component 140 is connected to the first transmission component 130, and the rotating first transmission component 130 can drive the second transmission component 140 to move through contact to achieve power transmission. The second transmission component 140 can be directly connected to the functional component, and can also be connected to other transmission components. When power is transmitted to the functional component, the functional component realizes the corresponding function of the cooking device 100 through movement.

[0067] For example, the functional component locks the inner pot 114 in the body 110 on the cover 116 in the body 110 by movement, or the functional component locks the pot body 112 and the cover 116 in the body 110 together by movement, or the functional component automatically pops the engaged cover 116 off the pot body 112 by movement. In this regard, this embodiment does not impose a rigid limitation on the specific use of power transmission, and it is sufficient to meet the need to transmit power through the first transmission component 130 and the second transmission component 140.

[0068] During operation, no matter the first transmission component 130 rotates on the shaft 120 or the shaft 120 drives the first transmission component 130 to rotate synchronously, the shaft 120 can provide radial positioning for the first transmission component 130. However, the positioning of the first transmission component 130 in the radial direction of the shaft 120 cannot be guaranteed, which causes the first transmission component 130 to be easily dislocated radially or even fall out of the shaft 120 during operation, so that the functional components cannot operate normally, the corresponding functions fail, and the reliability of the cooking device 100 is affected.

[0069] In this regard, the shaft body 120 proposed in the present application is provided with a limiting portion 1202, and the limiting portion 1202 cooperates with the second transmission component 140 to axially position the first transmission component 130. Specifically, in the axial direction of the shaft body 120, the limiting portion 1202 is located on the first side of the first transmission component 130, and the second transmission component 140 is located on the opposite side of the limiting portion 1202. The limiting portions 1202 and the second transmission component 140 distributed on both sides can clamp the first transmission component 130 therebetween. Among them, considering that thermal deformation of the structure is unavoidable, the matching accuracy of the transmission structure is related to the length of its own dimension chain. The longer the dimension chain of the transmission matching, the greater the amplitude of thermal deformation, and the greater the impact on the corresponding matching accuracy. In this regard, the first transmission component 130 that rotates during the transmission process has a smaller size in the axial direction. The first transmission component 130 is clamped and positioned in the axial direction by the limiting parts 1202 and the second transmission component 140 respectively located on both sides of the first transmission component 130, which can reduce the length of the dimension chain of the shaft body 120, the first transmission component 130 and the second transmission component 140, thereby reducing the amount of thermal deformation and the influence of thermal deformation on the transmission matching accuracy, thereby solving the technical problems existing in the related technology that the transmission structure is greatly affected by thermal deformation, the transmission reliability is poor, and the failure rate is high.

[0070] On the other hand, the clamping and positioning structure of the limit portion 1202 and the second transmission component 140 can also reduce the misalignment space of the first transmission component 130 in the axial direction, prevent the first transmission component 130 from detaching from the shaft body 120, and ensure that the first transmission component 130 can transmit power to the second transmission component 140.

[0071] It can be seen that by clamping the first transmission component 130 through the limiting portion 1202 on the shaft body 120 and the second transmission component 140, the first transmission component 130 can be axially positioned with the inherent shaft body 120 and the second transmission component 140 without adding a positioning structure.

[0072] On the other hand, the processing difficulty and production cost of the cooking device 100 can be reduced on the basis of meeting the axial positioning requirements, thereby achieving the technical effects of improving the structural stability and reliability of the cooking device 100, improving the transmission accuracy of the cooking device 100, and reducing the transmission failure rate of the cooking device 100.

[0073] Specifically, the limiting portion 1202 may be a limiting step provided on the shaft body 120 , and the limiting step may block the first transmission component 130 at the first side of the first transmission component 130 .

[0074] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, optionally, the first transmission component 130 includes a gear 132 , and the gear 132 is sleeved on the shaft 120 ; the second transmission component 140 includes a rack 142 , and the rack 142 is meshed with the gear 132 .

[0075] In this embodiment, the first transmission component 130 includes a gear 132, and the second transmission component 140 includes a rack 142. The gear 132 meshes with the rack 142. The rotating gear 132 can drive the rack 142 to move through meshing to achieve power transmission. Among them, the gear 132 is sleeved on the rotating shaft, and the rotating shaft can provide radial positioning for the gear 132 to ensure the meshing accuracy of the gear 132 and the rack 142 in the radial direction. The limiting portion 1202 and the partial area on the rack 142 can clamp the gear 132 in the axial direction of the gear 132 to ensure the meshing accuracy of the gear 132 and the rack 142 in the axial direction, ensure that the gear 132 can work at a predetermined position, and avoid transmission failures caused by the misalignment of the gear 132.

[0076] The gear 132 and the rack 142 have the advantage of low transmission precision. Selecting the gear 132 and the rack 142 to transmit power can ensure the action precision of the functional components and ensure the effective execution of the corresponding functions. At the same time, the gear 132 and the rack 142 also have the advantage of low transmission noise, which is conducive to reducing the working noise of the cooking device 100.

[0077] like Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9As shown, in some embodiments of the utility model, optionally, the gear 132 includes a first tooth portion 1322, the rack 142 includes a second tooth portion 1422, the first tooth portion 1322 and the second tooth portion 1422 are meshed, and the first transmission component 130 also includes: a boss 134, which is provided on the gear 132; along the axial direction of the shaft body 120, the limiting portion 1202 is located on the first side of the boss 134, and is opposite to the boss 134 and / or the gear 132, and the second tooth portion 1422 is located on the second side of the boss 134, and is opposite to the boss 134.

[0078] In this embodiment, the gear 132 is provided with a first tooth portion 1322 , and the rack 142 is provided with a second tooth portion 1422 adapted to the first tooth portion 1322 . The gear 132 and the rack 142 are meshed through the first tooth portion 1322 and the second tooth portion 1422 .

[0079] On this basis, the first transmission component 130 further includes a boss 134, which is disposed on the gear 132 and located on the first side of the gear 132. The surface of the boss 134 facing the limiting portion 1202 is the first surface, and the surface of the boss 134 facing the rack 142 is the second surface. After the first transmission component 130 and the second transmission component 140 are assembled, the boss 134 is located between the second tooth portion 1422 and the limiting portion 1202. The limiting portion 1202 can provide a block to the first surface, and the second tooth portion 1422 can provide a block to the second surface, thereby achieving axial positioning of the gear 132 and preventing the gear 132 from being misplaced or even falling out of the shaft 120.

[0080] By providing the boss 134, the axial movement of the gear 132 can be limited by the second tooth portion 1422 without affecting the meshing relationship between the gear 132 and the rack 142. At the same time, the structural complexity is relatively low, and the boss 134 can be integrally formed on the gear 132, which is conducive to reducing the cost of the cooking device 100 and providing convenient conditions for the miniaturization and lightweight design of the cooking device 100.

[0081] like Figure 4 As shown, in some embodiments of the present invention, optionally, in the axial direction of the shaft body 120 , the distance between the second tooth portion 1422 and the boss 134 is greater than or equal to 0.2 mm.

[0082] In this embodiment, in the axial direction of the shaft body 120 , the distance between the second tooth portion 1422 and the boss 134 is L1, where L1 needs to be greater than or equal to 0.2 mm, that is, there needs to be enough clearance between the second tooth portion 1422 and the boss 134 .

[0083] By setting a gap L1 between the second tooth portion 1422 and the boss 134, on the one hand, interference between the second tooth portion 1422 and the boss 134 can be avoided, the transmission resistance between the gear 132 and the rack 142 can be reduced, and the possibility of the gear 132 and the rack 142 being stuck can be reduced. On the other hand, the gap L1 can leave enough axial displacement margin for the gear 132 to prevent the gear 132 from moving and pushing the rack 142 away from the predetermined position. In this way, the transmission reliability and transmission accuracy of the gear 132 and the rack 142 can be improved, and the technical effect of improving the axial positioning stability of the gear 132 can be achieved.

[0084] like Figure 4 As shown, in some embodiments of the present invention, optionally, in the axial direction of the shaft body 120, the height of the first tooth portion 1322 is a first height; in the axial direction of the shaft body 120, the distance between the second tooth portion 1422 and the boss 134 is less than or equal to two-thirds of the first height.

[0085] In this embodiment, in the axial direction of the shaft body 120, the height of the first tooth portion 1322 is a first height H. Correspondingly, in the axial direction of the shaft body 120, the distance between the second tooth portion 1422 and the boss 134 is L1. Wherein, L1 and H satisfy the following relationship:

[0086] L1≤2÷3×H;

[0087] By limiting the above-mentioned dimensional relationship, it is possible to ensure that there is sufficient meshing depth between the first tooth portion 1322 and the second tooth portion 1422, thereby preventing the first tooth portion 1322 on the gear 132 from separating from the second tooth portion 1422 during movement, thereby reducing the possibility of disconnection between the gear 132 and the rack 142, and thereby achieving the technical effect of improving the transmission reliability of the gear 132 and the rack 142 and reducing the failure rate of the cooking device 100.

[0088] like Figure 3 As shown, in some embodiments of the present invention, optionally, in the radial direction of the gear 132 , the length of the overlapping area between the second tooth portion 1422 and the boss 134 is greater than or equal to 2 mm.

[0089] Figure 3 , the dot-dash line a shows the radial direction of the gear 132 .

[0090] In this embodiment, in the radial direction of the gear 132 and the rack 142, the length of the overlapped area between the second tooth portion 1422 and the boss 134 is L2, and L2 needs to be greater than or equal to 2 mm. Among them, the area on the second tooth portion 1422 that overlaps with the boss 134 in the radial direction can provide a barrier to the boss 134. By limiting the length L2 of the overlapped area to be greater than or equal to 2 mm, it can be ensured that the second tooth portion 1422 can effectively block the movement of the boss 134, reducing the possibility of the boss 134 knocking off the second tooth portion 1422, thereby achieving the technical effect of improving the transmission reliability of the gear 132 and the rack 142 and reducing the failure rate of the cooking device 100.

[0091] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments of the present invention, optionally, the boss 134 is annular, and the boss 134 and the gear 132 share a common axis.

[0092] In this embodiment, the boss 134 is annular, and the annular boss 134 can ensure that when the gear 132 rotates to any angle, the rack 142 can provide axial limitation for the boss 134 to avoid the occurrence of a limiting dead angle.

[0093] At the same time, the annular boss 134 also has an anti-foolproof function, which can reduce the possibility of the gear 132 being installed in reverse.

[0094] Specifically, when the working stroke of the gear 132 is less than 360°, the boss 134 may also be semi-annular, and the specific orbiting angle is adapted to the working of the gear 132 .

[0095] like Figure 1 , Figure 2 and Fig.10 As shown, in some embodiments of the present invention, optionally, the main body 110 includes: a pot body 112; an inner pot 114, which is arranged in the pot body 112; a cover body 116, which is connected to the pot body 112, and the cover body 116 is used to cover the inner pot 114; the cooking device 100 also includes: a locking assembly 150, which is arranged on the cover body 116 and connected to the second transmission component 140, and the locking assembly 150 is used to lock the inner pot 114 and / or the cover body 116.

[0096] In this embodiment, the main body 110 includes a pot body 112, an inner pot 114 and a cover 116. The inner pot 114 is embedded in the pot body 112. The pot body 112 is used to position, support and protect the inner pot 114. A cooking cavity is formed in the inner pot 114, and the food is cooked into finished food in the inner pot 114. The cover 116 is connected to the pot body 112, and the cover 116 can move relative to the pot body 112. When the cover 116 is in an open state, the cover 116 avoids the opening of the inner pot 114. At this time, the user can put in the food or take out the finished food, and can also remove the inner pot 114 for cleaning. When the cover 116 is in a closed state, the cover 116 covers the opening of the inner pot 114.

[0097] On this basis, the cooking device 100 further includes a locking component 150 . The locking component 150 corresponds to the functional component in the aforementioned content. The locking component 150 specifically includes a first locking component 150 and a second locking component 150 .

[0098] The first locking assembly 150 is disposed on the cover 116, and the first locking assembly 150 cooperates with the inner pot 114. Specifically, the first locking assembly 150 includes a first posture and a second posture. When the cover 116 is closed and the first locking assembly 150 is in the first posture, the first locking assembly 150 can be locked with the inner pot 114 in the pot body 112 to lock the inner pot 114 under the cover 116, thereby creating a closed cooking environment in the inner pot 114. In this case, the air pressure value in the inner pot 114 can be increased by heating the inner pot 114 to achieve a high-pressure cooking function. Correspondingly, when the first locking assembly 150 is in the second posture, the first locking assembly 150 releases the lock on the inner pot 114, and the opening of the inner pot 114 can be exposed by opening the cover 116.

[0099] The second locking assembly 150 is disposed on the pot body 112 and / or the cover body 116, and the second locking assembly 150 includes a third posture and a fourth posture. When the cover body 116 is closed and the second locking assembly 150 is in the third posture, the second locking assembly 150 can lock the inner pot 114 and the cover body 116 together to ensure that the cover body 116 can cover the inner pot 114, forming a closed environment in the inner pot 114, and facilitating pressure increase. When the cover body 116 is closed and the second locking assembly 150 is in the fourth posture, the second locking assembly 150 releases the locking relationship between the inner pot 114 and the cover body 116, and at this time, the cover body 116 is opened to expose the opening of the inner pot 114.

[0100] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the cooking device 100 further includes: a driving component 160 disposed on the cover body 116 , and the driving component 160 drives the first transmission component 130 to rotate through the shaft body 120 .

[0101] In this embodiment, the cooking device 100 further includes a driving component 160 , which is disposed on the cover 116 and connected to the shaft 120 . The driving component 160 can drive the gear 132 to rotate by driving the shaft 120 .

[0102] Specifically, a knob may be selected as the driving component 160 , and the user may rotate the gear 132 and the rack 142 by rotating the knob.

[0103] A motor may also be selected as the driving component 160 , and the motor drives the gear 132 and the rack 142 to rotate by forward and reverse rotation.

[0104] In some embodiments of the present invention, optionally, the cooking device 100 is: an electric rice cooker, a pressure cooker or an electric stew pot.
