The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0063] Currently, with the development of technology and the improvement of people's living standards, more and more cooking utensils have appeared in kitchens to meet different cooking needs and preferences. These utensils not only improve cooking efficiency but also enrich the flavor and nutrition of food.

[0064] There are many types of cooking appliances, including rice cookers, pressure cookers, and slow cookers. Taking a pressure cooker as an example, a pressure cooker uses steam pressure through a sealed system to speed up the cooking process. The working principle of a pressure cooker is to seal the air inside the pot, preventing steam from escaping, thus generating pressure higher than atmospheric pressure. This increased pressure raises the boiling point of water, allowing food to be cooked at a higher temperature, thereby shortening cooking time while preserving the food's nutrients and flavor.

[0065] Whether it's a pressure cooker used over an open flame or one heated electrically, ease of use and operability are the primary concerns for most users. The opening and closing mechanism of the pressure cooker, in particular, directly impacts its usability. The main components of a pressure cooker include the pot body and the lid, which is installed on the pot body and can be opened and closed. The lid and pot body are equipped with various opening and closing mechanisms to accommodate different usage needs and safety standards, mainly categorized as drop-type, screw-on type, and clamp type.

[0066] In related technologies, pressure cookers also include handles or clamps connected to the lid. The lid is opened or closed by turning the handle or prying the clamp. This requires two hands or continuous operation, which is cumbersome and inconvenient for users, and the manufacturing cost is high.

[0067] Therefore, please refer to the following: Figures 1 to 3 This application provides a cover 11 and a cooking appliance, which aims to improve the problem that cooking appliances in the related art are not easy to operate.

[0068] Cooking appliances may include one of pressure cookers, rice cookers, and slow cookers; this embodiment does not limit the specific type of cooking appliance. For ease of explanation, the cooking appliance in the following embodiment is a pressure cooker, and the advantages of the cooking appliance of this application will be described in detail.

[0069] Taking a pressure cooker as an example, the pot body usually consists of an outer pot and an inner pot. The inner pot is used to directly hold food and is detachably installed inside the outer pot, making it easy for users to clean and replace. It also prevents users from directly contacting the heated surface of the inner pot, reducing the risk of burns. The outer pot can act as an insulation layer to reduce heat loss, allowing the food in the inner pot to be heated more quickly and evenly.

[0070] The upper cover 1 is closable and fits over the pot body, which includes an outer shell, an outer pot, and an inner pot. The upper cover 1 includes a cover body 11, a pot lid 12, a transmission component 13, a transmission structure, and a limiting component 20. The pot lid 12 is disposed inside the cover body 11 and can rotate relative to the cover body 11 along the circumference of the upper cover 1. The pot lid 12 has a locking position for locking with the outer pot or the inner pot and an unlocking position for unlocking with the outer pot or the inner pot. The pot lid 12 is used to seal the outer pot to form a cooking cavity. The transmission component 13 is vertically and vertically mounted on the cover body 11 along the axial direction of the upper cover 1, so as to switch between a locked position and a released position. The transmission component 13 can be an irregular structure or a columnar structure, without specific limitations. It can be understood that when the transmission component 13 is in the locked position, the pot lid 12 is in the locked position, and when the transmission component 13 is in the released position, the pot lid 12 is in the released position. A transmission structure connects the transmission component 13 and the pot lid 12, and is configured to drive the pot lid 12 to rotate based on the lifting and lowering of the transmission component 13, so that the pot lid 12 can switch between a locked position and an unlocked position; a limiting component 20 is movably connected to the lid body 11, and engages with the transmission structure based on the pot lid 12 being in the unlocked position, so that the pot lid 12 tends to maintain the unlocked position. The upper cover 1 is approximately circular, with its circumference being the direction of its own circumference, and its axial direction being consistent with the direction of the axis at the circular part of the upper cover 1.

[0071] There are many ways for the lid 12 to lock onto the pot body. For example, the lid 12 may have threads on its outer periphery and a threaded groove on the inner wall of the pot body. When the lid 12 is in the locked position, the lid 12 and the pot body are locked together by the threads and the threaded groove. When the pot body is in the unlocked position, the threads and the threaded groove are spaced apart circumferentially on the lid 11. Another example is that the lid 12 may have a latching part on its outer periphery and a latching groove on the inner wall of the pot body. The lid 12 and the pot body are locked together by the latching part and the latching groove. When the pot body is in the unlocked position, the latching part and the latching groove are spaced apart circumferentially on the lid 11. These are just a few examples; a complete list is not provided here.

[0072] The transmission component 13 is mounted on the cover 11 in a lifting manner. The cover 11 needs to limit the circumferential movement of the transmission component 13 to prevent it from rotating. For example, the transmission component 13 has a limiting protrusion protruding in its circumferential direction, and the cover 11 has a guide groove recessed therein. The guide groove extends vertically, and the limiting protrusion extends into the guide groove. The circumferential movement of the transmission component 13 is limited by the cooperation between the groove wall of the guide groove and the limiting protrusion. Other examples are not listed here.

[0073] The transmission structure connects the transmission component 13 and the pot lid 12. It can be a single structure or a structure composed of multiple components. Its purpose is to synchronously drive the pot lid 12 to rotate relative to the lid body 11 during the lifting and lowering movement of the transmission component 13. For example, the transmission structure can be a gear set or a linkage structure, which is not limited here. Specifically: When opening the upper lid 1, the user operates the transmission component 13 in the lifting direction to switch from the locked position to the released position. The transmission component 13 drives the pot lid 12 to rotate through the transmission structure, causing the pot lid 12 to switch from the locked position to the unlocked position. The user can then continue to operate the transmission component 13 in the lifting direction to open the upper lid 1. When closing the upper lid 1, the user operates the transmission component 13 to close the inner pot of the upper lid 1. Then, the user operates the transmission component 13 in the lifting direction to switch from the released position to the locked position. The transmission component 13 drives the pot lid 12 to rotate through the transmission structure, causing the pot lid 12 to switch from the unlocked position to the locked position.

[0074] When the lid 12 is in the unlocked position, the limiting member 20 engages with the transmission structure. This engagement can take the form of a snap-fit ​​or abutment. For example, if the transmission structure has a groove, the limiting member 20 extends into the groove, thus restricting further movement of the transmission structure and maintaining its current position. Since the transmission structure is connected to both the lid 12 and the transmission component 13, when the limiting member 20 engages with the transmission structure, the transmission structure also acts on the lid 12 and the transmission component 13, keeping them relatively stationary relative to the transmission structure. This allows the lid 12 to remain in the unlocked position and the transmission component 13 to remain in the released position.

[0075] It is understood that the cooperation between the limiting member 20 and the transmission structure provides a tendency for the pot lid 12 to maintain the unlocked position. When the force acting on the transmission member 13 is greater than the cooperation force between the limiting member 20 and the transmission structure, the limiting member 20 and the transmission structure can release the limiting cooperation state without damage, allowing the transmission member 13, the transmission structure and the pot lid 12 to move.

[0076] The lid 1 and cooking appliance provided in this application embodiment allow the user to operate the transmission component 13 in the lifting direction, so that the transmission component 13 switches from the locked position to the released position. The transmission component 13 drives the pot lid 12 to rotate through the transmission structure, so that the pot lid 12 switches from the locked position to the unlocked position. The user can open the lid 1 by lifting the transmission component 13. At the same time, when closing the lid 1, the user only needs to close the lid 1 by using the transmission component 13 and switch the transmission component 13 from the released position to the locked position. The transmission component 13 drives the pot lid 12 to rotate through the transmission structure, so that the pot lid 12 switches from the unlocked position to the locked position. This reduces the complexity of user operation, makes it easier for users to use the cooking appliance, simplifies the overall structure of the lid 1, and reduces costs.

[0077] This application embodiment also sets a limiting member 20 to cooperate with the transmission structure to limit the movement. After the operation of the transmission member 13 causes the pot lid 12 to switch to the unlocked position, the pot lid 12 and the transmission member 13 can maintain the switched position, so that the pot lid 12 is not affected by gravity in the unlocked position, avoiding the user from continuously or repeatedly operating the transmission member 13, further improving the ease of operation of the lid 1 and the cooking utensil, and improving the user experience.

[0078] Of course, in some embodiments of this application, when the lid 12 is in the unlocked position and the locked position, the limiting member 20 is in limiting cooperation with the transmission structure, so that the lid 12 can maintain the unlocked position and the locked position, and the transmission member 13 maintains the locked position and the released position. This not only improves the ease of operation of the lid 1 and the cooking utensil, but also further improves the stability of the lid 12 when it is in the locked position, and prevents the lid 12 from loosening.

[0079] In some embodiments, the transmission structure includes a driven member 14 and a transmission assembly. The driven member 14 is rotatably mounted on the lid 11 and connected to the transmission member 13, so that it can be driven to rotate by the transmission member 13. The transmission structure drives the driven member 14 and the lid 12, and is used to drive the lid 12 to rotate when the driven member 14 rotates. That is, in this embodiment, the cooperation between the driven member 14 and the transmission member 13 realizes the conversion of the lifting motion of the transmission member 13 into the rotation of the driven member 14, and the transmission structure transmits the rotation of the driven member 14 to the lid 12, driving the lid 12 to rotate. The transmission member 13 moves up and down along its centerline, and the centerline of the transmission member 13 is collinear with the rotation axis of the driven member 14. It can be understood that the driven member 14 rotates around the centerline of the transmission member 13. The transmission member 13 can move on the rotation axis of the lid 12, or it can move at a position spaced apart from the rotation axis in the radial direction of the lid 12, without specific limitation.

[0080] For example, please refer to Figures 4 to 6 One of the transmission member 13 and the driven member 14 is provided with a spiral groove 15, and the other of the transmission member 13 and the driven member 14 is provided with a driving part 16. The driving part 16 is inserted into the spiral groove 15. When the transmission member 13 switches from the locked position to the released position, the transmission member 13 drives the driven member 14 to rotate through the cooperation of the driving part 16 and the spiral groove 15, and drives the pot lid 12 to rotate from the locked position to the unlocked position. In this way, the conversion of the lifting motion of the transmission member 13 to the rotation of the driven member 14 can be achieved in a simple structure.

[0081] It is understood that the driving part 16 can be disposed on the transmission member 13, in which case the helical groove 15 is disposed on the driven member 14; alternatively, the driving part 16 can be disposed on the driven member 14, in which case the helical groove 15 is disposed on the transmission member 13. The driving part 16 can have many shapes; it can be cylindrical, square, or other shapes, without specific limitations. Preferably, the driving part 16 is cylindrical, which reduces wear between the outer peripheral wall of the driving part 16 and the groove wall of the helical groove 15.

[0082] It should be noted that the downward projection of the spiral groove 15 is located on the circumference of a circle, and the center line of the transmission component 13 of this application is a line that extends along its own lifting direction and passes through the center of the aforementioned circle.

[0083] In some embodiments of this application, there are multiple spiral grooves 15, which are spaced apart in the rotation direction of the pot lid 12. There are also multiple driving units 16, each corresponding to a spiral groove 15. This arrangement improves the transmission stability between the transmission member 13 and the driven member 14 through the cooperation of multiple driving units 16 and spiral grooves 15. Furthermore, if one driving unit 16 or one spiral groove 15 is damaged, the transmission member 13 can still be rotated by the cooperation of the remaining driving units 16 and spiral grooves 15, thereby extending the service life of the transmission member 13 and the driven member 14.

[0084] There are many possible positional relationships between the transmission member 13 and the driven member 14. For example, the transmission member 13 can be fitted onto the outer peripheral wall of the driven member 14 by providing a groove, or the driven member 14 can be fitted onto the outer peripheral wall of the transmission member 13 by providing a groove. No specific limitation is made here.

[0085] In some embodiments of this application, please refer to Figure 4 The cover 11 has a movable channel 111 extending through it along the lifting direction of the transmission member 13. One end of the transmission member 13 is connected to the driven member 14, and the other end of the transmission member 13 passes through the movable channel 111. This arrangement allows the transmission member 13 to be limited by the movable channel 111, thereby ensuring that the transmission member 13 moves in the lifting direction and preventing the transmission member 13 from detaching from the cover 11.

[0086] Furthermore, the upper cover 1 also includes a handle 10c. One end of the handle 10c passes through the movable channel 111 and connects to the transmission component 13, while the other end extends out of the cover 11, facilitating user grip and operation and improving the user experience. The handle 10c can have various shapes; it can be arched, "7"-shaped, or any other shape that facilitates user gripping. No specific limitations are made here. The handle 10c can be installed on the transmission component 13 in various ways. It can be integrally formed with the transmission component 13, reducing the number of parts, lowering costs, and improving structural integrity. Alternatively, it can be installed via a threaded connection or a snap-fit ​​mechanism. Preferably, the handle 10c and transmission component 13 are detachably connected. If the handle 10c assembly or the transmission component 13 is damaged, only the corresponding part needs to be replaced, thereby reducing future maintenance costs.

[0087] In this embodiment, the limiting member 20 is limited to the transmission assembly. It can be seen that since the transmission assembly is used to drive the rotation of the driven member 14 to the pot lid 12, the limiting member 20 is matched with the transmission assembly to avoid the driven member 14 having an additional structure that matches the limiting member 20, thereby reducing the structural complexity of the driven member 14 and making it easier to manufacture.

[0088] Combination Figure 3 In some embodiments of this application, the centerline of the transmission member 13 is spaced apart from the rotation axis of the pot lid 12, and the outer peripheral wall of the driven member 14 is provided with a first transmission tooth 143. The transmission assembly includes a first rotating member 18 and a second rotating member 19. The first rotating member 18 is rotatably mounted on the lid 11 and is provided with a first driven tooth 181 and a second transmission tooth 182 spaced apart from the first driven tooth 181. The first driven tooth 181 meshes with the first transmission tooth 143. The second rotating member 19 is movably mounted on the lid 11 to slide around the rotation axis of the pot lid 12. The second rotating member 19 is provided with a second driven tooth 191, which meshes with the second transmission tooth 182. With this configuration, the transmission member 13 moves in the lifting direction, causing the driven member 14 to rotate. The driven member 14, through the engagement of the first transmission tooth 143 and the first driven tooth 181, causes the first rotating member 18 to rotate. The first rotating member 18, through the second transmission tooth 182 and the second driven tooth 191, causes the pot lid 12 to rotate. This application uses a two-stage transmission system with a first rotating member 18 and a second rotating member 19, which has a reasonable structural arrangement. Furthermore, the driven member 14 and the first rotating member 18, as well as the first rotating member 18 and the second rotating member 19, are connected by the cooperation of transmission teeth and driven teeth, resulting in high transmission accuracy and reliability.

[0089] Please see Figure 2 and Figure 3The lid 12 has a pressure relief port 121 at the center of its own rotation axis. The rotation axis of the first rotating member 18 is spaced apart from the rotation axis of the lid 12. The upper cover 1 also includes an exhaust valve 17, which is movably installed in the pressure relief port 121 to open or close the pressure relief port 121. In this embodiment, the transmission member 13 avoids the rotation axis of the lid 12 through the first rotating member 18 and the second rotating member 19. Therefore, when the lid 12 and the driven member 14 rotate, the exhaust valve 17 will not interfere with the lid 12, ensuring smooth exhaust.

[0090] In this embodiment, the limiting member 20 engages with at least one of the first rotating member 18 and the second rotating member 19. That is, the limiting member 20 can engage with the first rotating member 18 alone, or with the second rotating member 19 alone, or with both the first rotating member 18 and the second rotating member 19 simultaneously; this embodiment does not limit the specific engagement. Since both the first rotating member 18 and the second rotating member 19 rotate, the engagement of the limiting member 20 with both is easier to achieve, and the structure can be simpler.

[0091] Specifically, in combination Figure 3 , Figure 7 as well as Figure 8 The second rotating component 19 is arranged in a fan-shaped ring, and a second driven tooth 191 is provided on the inner side of the second rotating component 19. This arrangement facilitates the machining of the second rotating component 19. At the same time, during the installation of the second rotating component 19, it is only necessary to overlap the center of the fan ring with the rotation axis of the pot lid 12 to ensure that the movement direction of the second rotating component 19 is around the rotation axis of the pot lid 12, thereby facilitating the assembly of the second rotating component 19.

[0092] In this embodiment, the inner side of the second rotating member 19 is also provided with at least two limiting parts 193. The at least two limiting parts 193 are spaced apart along the sliding direction of the second rotating member 19. The limiting member 20 is located inside the second rotating member 19. When the transmission member 13 is in the locked position and the released position, the limiting member 20 and the at least two limiting parts 193 respectively limit and cooperate.

[0093] like Figure 7 and Figure 8Taking the second rotating member 19 having two limiting parts 193 on its inner side as an example, when the transmission member 13 is in the locked position, the limiting member 20 engages with one of the limiting parts 193; when the transmission member 13 is in the released position, the limiting member 20 engages with the other limiting part 193. When the transmission member 13 is in the locked and released positions, the second rotating member 19 is restricted from rotating by the limiting member 20, so that the first rotating member 18 remains in its current position. This allows the transmission member 13 to be stably in the locked and released positions, while the lid 12 is stably in the locked and unlocked positions, facilitating user operation.

[0094] Of course, in other embodiments, the second rotating member 19 may also be provided with only a limiting part 193, which is used to limit the rotation of the second rotating member 19 by the limiting part 20 when the transmission member 13 is in the locked position or the released position, so that the first rotating member 18 maintains the current position, thereby enabling the transmission member 13 to be stably in the locked position or the released position, and the pot lid 12 to be stably in the locked position or the unlocked position.

[0095] In this embodiment, the limiting part 193 is disposed inside the second rotating member 19, which facilitates processing. Correspondingly, the limiting part 20 is also located inside the second rotating member 19, which facilitates structural arrangement and improves the space utilization of the cover 11.

[0096] In some embodiments, the limiting portion 193 is a limiting groove, and the limiting member 20 has a limiting end 22 located within the limiting groove, so that the limiting member 20 and the limiting portion 193 are in a limiting engagement, or the limiting end 22 disengages from the limiting groove, and the limiting member 20 and the limiting portion 193 are released from the limiting engagement. The limiting member 20 can abut against the inner side of the second rotating member 19 under the action of external force, and can slide relative to the inner side of the second rotating member 19. When the second rotating member 19 rotates to a limiting groove that aligns with the limiting member 20, the limiting end 22 extends into the limiting groove, and the limiting end 22 interacts with the groove wall of the limiting groove, so that the limiting member 20 and the limiting portion 193 achieve a limiting engagement and block the rotation of the second rotating member 19. When the user increases the force applied to the transmission component 13 by the handle 10c until the first rotating component 18 drives the second rotating component 19 to rotate, causing the limiting groove to overcome the force between itself and the limiting end 22, the limiting end 22 disengages from the limiting groove and returns to abutting the inner surface of the second rotating component 19. Thus, through the cooperation of the limiting end 22 and the limiting groove, the limiting engagement and disengagement of the limiting part 193 and the limiting component 20 can be achieved, resulting in a simple and effective structure.

[0097] Optionally, the limiting part 193 is disposed on the side of the second driven tooth 191, making the overall structure of the transmission structure and the limiting member 20 more compact.

[0098] Combination Figure 2 and Figure 3In one embodiment, the cover 11 is provided with a connecting groove 117, the opening of the connecting groove 117 facing the inner side of the second rotating member 19. The limiting member 20 includes an elastic member 21 installed in the connecting groove 117. The elastic member 21 can elastically extend and retract along the radial direction of the upper cover 1. The limiting end 22 is formed at one end of the elastic member 21 near the second rotating member 19, so that the limiting end 22 can slidably abut against the inner side of the second rotating member 19 and has a tendency to move into the limiting groove.

[0099] Optionally, the elastic element 21 can be a spring, with one end of the spring connected to the bottom wall of the connecting groove 117. The limiting element 20 also includes a top end connected to the other end of the spring, which forms the limiting end 22 of the limiting element 20. The spring elastically expands and contracts radially along the upper cover 1, and the top end can extend into or exit the limiting groove. Of course, the elastic element 21 can also be an integral rubber structural component or other elastic structure, with one end of itself forming the aforementioned limiting end 22, which is not limited here.

[0100] Understandably, when the lid 12 is not in the locked or unlocked position, the limiting end 22 abuts against the inner side of the second rotating member 19, and the elastic member 21 is compressed and has elastic potential energy. When the lid 12 is not in the locked or unlocked position, the limiting end 22 is aligned with a limiting groove, and the limiting end 22 extends into the limiting groove under the elastic action of the elastic member 21. Optionally, when the limiting end 22 is located in the limiting groove, the elastic member 21 may still be in a compressed state and have elastic potential energy to make the limiting end 22 abut against the inner wall of the limiting groove, thereby increasing the interaction force between the limiting end 22 and the inner wall of the limiting groove and improving the stability of the fit between the limiting member 20 and the limiting part 193. In addition, the connecting groove 117 of this application can extend radially along the upper cover 1, the elastic member 21 can elastically expand and contract radially along the upper cover 1, and the second rotating member 19 can rotate around the central axis of the pot lid 12. In this way, on the one hand, the design length of the elastic member 21 can be shortened and the cost can be reduced, and on the other hand, the stability of the force between the limiting end 22 and the limiting groove and the inner side of the second rotating member 19 can be further guaranteed, making it less prone to instability and with high structural reliability.

[0101] It is worth mentioning that the opening of the limiting groove is smoothly connected to the rest of the inner side of the second rotating member 19, which facilitates the insertion and removal of the limiting end 22, prevents the second rotating member 19 from getting stuck, and improves the user experience.

[0102] In one embodiment, please refer to Figure 3One of the driven member 14 and the cover 11 is provided with a first guide groove 145, and the other is provided with a first guide post 118. The first guide groove 145 extends along the rotation direction of the driven member 14, and the first guide post 118 passes through the first guide groove 145. That is, the driven member 14 can be provided with the first guide groove 145 and the first guide post 118 can be provided on the cover 11, or the cover 11 can be provided with the first guide groove 145 and the first guide post 118 can be provided on the driven member 14. The cooperation between the first guide post 118 and the first guide groove 145 not only maintains the stability of the rotation of the driven member 14, but also limits the rotational stroke of the driven member 14. For example, when the transmission component 13 is in the locked position, the first guide post 118 is located at one end of the first guide groove 145. When the transmission component 13 is in the released position, the first guide post 118 is located at the other end of the first guide groove 145. In this way, the first guide groove 145 can limit the first guide post 118 so that when the transmission component 13 is in the locked position and the released position, the position of the driven component 14 remains unchanged, which further helps to ensure the stability of the positions of the transmission component 13 and the pot lid 12.

[0103] Furthermore, combined Figure 7 or Figure 8 One of the second rotating member 19 and the cover 11 is provided with a second guide groove 192, and the other is provided with a second guide post 119. The second guide groove 192 extends along the sliding direction of the second rotating member 19, and the second guide post 119 passes through the second guide groove 192. That is, the second rotating member 19 can be provided with the second guide groove 192, and the second guide post 119 can be provided on the cover 11, or the cover 11 can be provided with the second guide groove 192, and the second guide post 119 can be provided on the second rotating member 19. The cooperation between the second guide post 119 and the second guide groove 192 not only maintains the stability of the rotation of the second rotating member 19, but also limits the rotational stroke of the second rotating member 19, thereby further improving the positional stability of the transmission member 13 and the pot lid 12.

[0104] Taking the second rotating member 19 having a second guide groove 192 as an example, the second rotating member 19 can be provided with two or more second guide grooves 192. The multiple second guide grooves 192 are arranged radially along the upper cover 1. Correspondingly, the cover body 11 is provided with two or more second guide posts 119. One second guide post 119 is correspondingly inserted into one second guide groove 192, so as to further improve the movement stability of the second rotating member 19.

[0105] In some embodiments of this application, please refer to Figure 3The outer peripheral wall of the first rotating member 18 is provided with a connecting portion 183, and the surface of the connecting portion 183 in the radial direction of the first rotating member 18 is provided with a first driven tooth 181. The cover 11 is provided with a limiting protrusion 112. When the transmission member 13 is in the locked or released position, the surface of the connecting portion 183 in the circumferential direction of the first rotating member 18 abuts against the limiting protrusion 112. With this configuration, the abutment between the limiting protrusion 112 and the connecting portion 183 avoids interference between the connecting portion 183 and the exhaust valve 17. At the same time, the rotation amplitude of the first rotating member 18 can be limited. Thus, the first rotating member 18 limits the rotation amplitude of the driven member 14 through the first driven tooth 181 and the first transmission tooth 143. In turn, the driven member 14 limits the movement amplitude of the transmission member 13 through the spiral groove 15 and the drive portion 16.

[0106] Please see Figure 2 and Figure 3 In one embodiment, the first driven tooth 181 and the second transmission tooth 182 are spaced apart in the lifting direction, and the first transmission tooth 143 and the second driven tooth 191 are spaced apart in the lifting direction. This arrangement avoids interference between the driven member 14 and the second rotating member 19, while making full use of the space of the upper cover 1 in the lifting direction of the transmission member 13.

[0107] Furthermore, the second transmission tooth 182 is closer to the rotation axis of the first rotating member 18 than the first driven tooth 181, or in other words, the radius of the second transmission tooth 182 is smaller than the radius of the first driven tooth 181 relative to the rotation axis of the first rotating member 18. This further offsets the first driven tooth 181 and the second transmission tooth 182, thereby further separating the driven member 14 and the second rotating member 19 radially in the upper cover 1, avoiding interference and facilitating spatial arrangement and assembly. On the other hand, the larger radius of the first driven tooth 181 also facilitates driving the second rotating member 19, preventing jamming and ensuring smooth transmission connection.

[0108] In some embodiments of this application, please refer to Figure 3The lid 11 is provided with a guide channel 113 extending circumferentially along the lid 12, and the guide channel 113 extends through the lid in the lifting direction. The upper lid 1 also includes a guide device 10a, one end of which is fixedly connected to the lid 12, and the other end of which at least partially extends into the guide channel 113. This arrangement guides the rotation of the lid 12. There can be multiple guide devices 10a, spaced apart circumferentially along the lid 12. The number of guide devices 10a can vary; for example, multiple guide devices 10a may be installed within a single guide channel 113; multiple guide channels 113 may be provided, with each guide channel corresponding to a guide device 10a; or multiple guide channels 113 may be provided, with some guide devices 10a installed within the same guide channel 113. These variations are not listed here.

[0109] For further clarification, please refer to [link / reference]. Figure 2 The cover 11 may include two parts: a face cover 115 and an inner cover 116. The face cover 115 covers the outer surface of the inner cover 116. The face cover 115 may partially or completely cover the outer surface of the inner cover 116. The aforementioned transmission structure and driven member 14 are located on the upper surface of the inner cover 116 and are covered by the face cover 115, thus not being exposed. The structure is relatively aesthetically pleasing.
