Detailed Implementation

[0045] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0046] In related technologies, the lid and pot of a pressure cooker are typically fitted together using a locking mechanism. This mechanism usually employs latches and latches, with one latch on the lid and the other on the pot. A column is mounted on the lid. Before pressure cooking, the column can be operated to rotate the lid in one direction, engaging the latches and locking the lid to the pot. To open the lid, the column can be operated to rotate the lid in the opposite direction, disengaging the latches and separating the lid from the pot. Because pressure cookers operate under high pressure, metal lids are typically used to withstand this pressure. The column needs to be welded to the lid, requiring a high degree of flatness in the welding surface. For example, if the welding surface is curved, the lid structure needs to be modified or a new location for the column needs to be found, resulting in difficult and time-consuming assembly, and significant limitations on the lid's shape design. Therefore, this application proposes a pot lid assembly 100 to solve the aforementioned technical problems.

[0047] like Figures 1 to 4As shown, a pot lid assembly 100 according to a first aspect of the present disclosure includes: a housing portion; a hanging shaft portion 120 rotatably disposed on the housing portion; a lid portion 130 whose center is fixedly connected to the hanging shaft portion 120; a first gear 140 fixedly connected to the hanging shaft portion 120; a second gear 150 meshing with the first gear 140; and a drive portion connected to the second gear 150 for driving the second gear 150 to rotate.

[0048] It is understood that the pot lid assembly 100 provided in this embodiment includes a housing portion, a hanging shaft portion 120, a lid portion 130, a first gear 140, a second gear 150, and a drive portion. The hanging shaft portion 120 is rotatably disposed on the housing portion, and the center of the lid portion 130 is fixedly connected to the hanging shaft portion 120, and can move synchronously with the hanging shaft portion 120. The first gear 140 is fixedly connected to the hanging shaft 120, and the first gear 140 and the second gear 150 mesh with each other. The second gear 150 is connected to the drive unit so that the drive unit can drive the second gear 150 to rotate. The second gear 150 is the driving gear, and the first gear 140 is the driven gear. The second gear 150 drives the first gear 140 to rotate, so that the rotation of the first gear 140 can drive the hanging shaft 120 to rotate, thereby causing the hanging shaft 120 to drive the lid part 130 to rotate relative to the shell part, so as to realize the locking or unlocking of the lid part 130 on the pot body. Moreover, the hanging shaft 120 can drive the lid part 130 to rotate through the gear transmission, without the need to set other structures on the lid part 130 for cooperating with the gear, thus eliminating the need to consider the shape and flatness of the mounting surface of the lid part 130, reducing the design and assembly difficulty of the pot lid assembly 100.

[0049] Understandably, the lid portion 130 is rotatable relative to the shell portion. With this configuration, when it is necessary to lock the lid assembly 100 to the pot body or separate the lid assembly 100 from the pot body, only the drive unit needs to drive the second gear 150 to rotate, which in turn drives the first gear 140 to rotate the hanging shaft portion 120, thereby rotating the lid portion 130. There is no need to rotate the entire lid assembly 100, saving time and effort during adjustment and improving the user experience.

[0050] It should be noted that the lifting shaft 120 can be located in the middle of the housing portion and connected to the middle of the cover portion 130. This arrangement ensures that when the housing portion and cover portion 130 are assembled, their centers coincide, guaranteeing a tight connection. It also ensures that the shapes of the cover portion 130 and the housing portion match, and that the rotation center of the lifting shaft coincides with the rotation center of the cover portion 130. This prevents the cover portion 130 from eccentrically moving relative to the lifting shaft, which could cause it to hit the side wall of the housing during rotation, thus ensuring smooth rotation. The housing portion can be provided with a rotating bracket 112 and a rotating shaft 113. The rotating shaft 113 is mounted on the rotating bracket 112, and the second gear 150 can be inserted into the rotating shaft 113 and mounted on the rotating bracket 112 to ensure the rotational stability of the second gear 150.

[0051] For example, the lid part 130 may be provided with a fastening position, and the corresponding pot body may be provided with a fastening tooth. After the pot lid assembly 100 is placed on the pot body in the indicated initial position, the user can adjust the rotation direction of the second gear 150 by operating the drive unit, so that the lid part 130 rotates relative to the pot body, and the fastening position is screwed onto the fastening tooth, so that the lid part 130 is locked to the pot body.

[0052] In some examples, such as Figures 1 to 4 As shown, the housing portion includes: a first housing 110, the hanging shaft portion 120 rotatably passing through the first housing 110, the cover portion 130 located on one side of the first housing 110, and the first gear 140 and the second gear 150 located on the other side of the first housing 110.

[0053] It is understood that the housing portion may be provided with a first housing 110. Specifically, the first housing 110 may have a mounting hole, and a mounting edge is formed around the mounting hole. The hanging shaft portion 120 can pass through the mounting hole and be rotatably mounted on the mounting edge. In the vertical direction, the projected area of ​​the first housing 110 is larger than the projected area of ​​the cover portion 130, so that the first housing 110 can cover the cover portion 130, and the cover portion 130 can be located on one side of the first housing 110. An installation space may be formed on the other side of the first housing 110, and the first gear 140 and the second gear 150 are both located in the installation space. The first gear 140 is connected to the hanging shaft portion 120 to drive the hanging shaft portion 120 to rotate. The first housing 110 separates the first gear 140 and the second gear 150 from the cover portion 130, ensuring stable transmission of the first gear 140 and the second gear 150, reducing interference caused by pressure cooking, and improving reliability.

[0054] For example, an annular groove may be provided around the mounting hole of the first housing 110, and an opening may be provided in the annular groove. Correspondingly, a protrusion is provided around the end of the lifting shaft 120 connected to the first housing 110. With this configuration, when the lifting shaft is installed in the first housing 110, the protrusion can be aligned with the opening first, and the lifting shaft 120 can be rotated to offset the protrusion and the opening, so that the protrusion is inserted into the annular groove. The vertical degree of freedom of the lifting shaft 120 is restricted by the annular groove, and the rotation of the lifting shaft 120 can be guided by the annular groove to ensure smooth rotation.

[0055] In some examples, such as Figures 1 to 4 As shown, the first gear 140 has a plurality of first grooves 141 formed on the side facing the housing portion; and / or the second gear 150 has a plurality of second grooves 151 formed on the side facing the housing portion; and / or the first housing 110 has a plurality of third grooves 111 and / or a plurality of fourth grooves formed on one side, wherein the third grooves 111 are arranged corresponding to the first gear 140 and the fourth grooves are arranged corresponding to the second gear 150.

[0056] It is understood that a first groove 141 can be formed on the side of the first gear 140 where it is mounted on the housing portion. By providing the first groove 141, the protrusion of the housing portion's surface facing the first gear 140 can be avoided, and the contact area between the first gear 140 and the housing portion can be reduced. This ensures smooth rotation of the first gear 140 while reducing friction between it and the housing portion, reducing frictional wear, and extending the service life of both the first gear 140 and the housing portion. Furthermore, multiple first grooves 141 can be provided, arranged at intervals, to further improve the wear resistance of the first gear 140, reduce its overall weight, and facilitate transmission with the second gear 150.

[0057] It should be noted that a third groove 111 may be formed on the side of the first housing 110 facing the first gear 140 and the second gear 150. The third groove 111 may be arranged corresponding to the first gear 140. By setting the third groove 111, the contact area between the first housing 110 and the first gear 140 can be reduced, thereby further ensuring the smooth rotation of the first gear 140 while reducing friction between it and the housing, reducing frictional wear between the first gear 140 and the housing, and extending the service life of the first gear 140 and the housing. Furthermore, multiple first grooves 141 may be provided, and multiple first grooves 141 are arranged at intervals to further improve the wear resistance of the housing.

[0058] It is understood that a second groove 151 can be formed on the side of the second gear 150 where it is mounted on the housing portion. By providing the second groove 151, the protrusion of the housing portion's surface facing the second gear 150 can be avoided, and the contact area between the second gear 150 and the housing portion can be reduced. This ensures smooth rotation of the second gear 150 while reducing friction with the housing portion, reducing frictional wear between the second gear 150 and the housing portion, and extending the service life of both the second gear 150 and the housing portion. Furthermore, multiple second grooves 151 can be provided, arranged at intervals, to further improve the wear resistance of the second gear 150, reduce the overall weight of the second gear 150, and facilitate transmission with the first gear 140.

[0059] It should be noted that a fourth groove may be formed on the side of the first housing 110 facing the first gear 140 and the second gear 150. The fourth groove may be arranged corresponding to the second gear 150. By providing the fourth groove, the contact area between the first housing 110 and the second gear 150 can be reduced, thereby further ensuring the smooth rotation of the second gear 150 while reducing friction between it and the housing, reducing frictional wear between the second gear 150 and the housing, and extending the service life of the second gear 150 and the housing. Furthermore, multiple fourth grooves may be provided, and the multiple fourth grooves are arranged at intervals to further improve the wear resistance of the housing.

[0060] In some examples, such as Figure 3 and Figure 4 As shown, the pot lid assembly 100 further includes a first limiting part 160, which is connected between the lid part 130 and the first gear 140.

[0061] It is understood that the lid assembly 100 may also be provided with a first limiting part 160. The first limiting part 160 limits the relative position of the first gear 140 and the lid part 130 so that when the first gear 140 rotates, it can drive the lid part 130 to rotate synchronously.

[0062] For example, the first limiting part 160 may be a limiting post, which may be vertically disposed at the end of the cover part 130 facing the first housing 110. The first gear 140 may have a connecting hole in the vertical direction, through which the first gear 140 passes to the limiting post. The cross-section of the limiting post and the shape of the connecting hole may both be elliptical to limit the relative rotation between the first gear 140 and the limiting post, ensuring that the first gear 140 can drive the cover part 130 to rotate synchronously when rotating. The limiting post and the cover part 130 may be an integrated structure. Correspondingly, the first housing 110 may have an arc-shaped groove, in which the limiting post may be inserted, guiding the movement of the limiting post and limiting its range of movement.

[0063] In some examples, such as Figure 3 and Figure 4 As shown, there is a gap between the axial position of the aforementioned hanging shaft portion 120 and the aforementioned first limiting portion 160.

[0064] It is understandable that since the first gear 140 drives the cover portion 130 to rotate via the first limiting portion 160, the line connecting the axis of the first limiting portion 160 and the axis of the hanging shaft portion 120 can serve as the rotational force arm of the cover portion 130. Therefore, forming a gap between the axis of the hanging shaft portion 120 and the first limiting portion 160 ensures that a rotational force arm is formed between the axis of the first limiting portion 160 and the axis of the hanging shaft portion 120.

[0065] It should be noted that if the rotation arm between the axis of the first limiting part 160 and the axis of the hanging shaft 120 is too short, a large driving force is required to drive the lid part 130 to rotate. If the rotation arm between the axis of the first limiting part 160 and the axis of the hanging shaft 120 is too long, the size of the lid part 130 will be too large, affecting the storage area occupied by the entire lid assembly 100. Therefore, the first limiting part 160 can be set at the edge of the lid part 130 to maximize the rotation arm while meeting the design requirements of the lid part 130, facilitating the rotation of the lid part 130 and improving the user experience.

[0066] In some examples, such as Figures 1 to 4 As shown, the first gear 140 is a sector gear; and / or the second gear 150 is a sector gear.

[0067] It is understandable that the first gear 140 can be a first sector gear, and the second gear 150 can be a second sector gear. The first sector gear and the second sector gear mesh with each other so that when the operating drive component drives the second sector gear to rotate, the second sector gear can drive the first sector gear to rotate, and the first sector gear can drive the cover part 130 to rotate relative to the housing part. While playing a transmission role, the sector gear can increase the torque output and improve the rotation efficiency of the rotating cover part 130. Furthermore, the sector gear can complete high-power transmission operations in a relatively small space, which is beneficial for placing it on the other side of the first housing 110, reducing the space occupied by the first gear 140 and the second gear 150, facilitating the rational planning and utilization of the internal space of the pot lid assembly 100, and contributing to the overall miniaturization design of the pot lid assembly 100.

[0068] In some examples, such as Figures 1 to 4As shown, the first gear 140 is a sector gear, and the pot lid assembly 100 further includes: a second limiting part 170 disposed in the housing part; and a third limiting part 180 disposed in the housing part. The second limiting part 170 and the third limiting part 180 are arranged at intervals along the rotation direction of the first gear 140; wherein the first gear 140 is rotatable between the second limiting part 170 and the third limiting part 180.

[0069] It is understandable that, when the first gear 140 is a sector gear, the pot lid assembly 100 may also be provided with a second limiting part 170 and a third limiting part 180. Specifically, the second limiting part 170 may be located at the other end of the first housing 110, and the second limiting part 170 may be located on one side of the first gear 140. When the first gear 140 rotates in the first direction, it may abut against the second limiting part 170, thereby limiting the first gear 140 from continuing to rotate in the first direction. The second limiting part 170 is located at the other end of the first housing 110, and the third limiting part 180 may be located on the other side of the first gear 140. When the first gear 140 rotates in the second direction, it may abut against the third limiting part 180, thereby limiting the first gear 140 from continuing to rotate in the second direction. The first direction and the second direction are opposite. The rotation range of the first gear 140 can be limited by the cooperation of the second limiting part 170 and the third limiting part 180, so as to avoid the first gear 140 rotating too much and causing the second gear 150 to separate, thereby improving reliability.

[0070] For example, the second limiting part 170 may be a protrusion located on one side of the first gear 140. When the first gear 140 rotates in the first direction, it can abut against the protrusion to limit the first gear 140 from continuing to rotate in the first direction. The third limiting part 180 may be a rib protruding from the other side of the first housing 110. There may be multiple ribs, arranged at intervals on the other side of the first gear 140. When the first gear 140 rotates in the second direction, it can abut against the rib to limit the first gear 140 from continuing to rotate in the second direction. The rib can also improve the structural strength of the housing part.

[0071] In some examples, such as Figures 5 to 10 As shown, the pot lid assembly 100 further includes a stop 190 for restricting the axial movement of the first gear 140 and the second gear 150.

[0072] It is understandable that the first gear 140 and the second gear 150 mesh with each other. During the transmission process of the first gear 140 and the second gear 150, axial movement can easily occur, causing the first gear 140 and the second gear 150 to disengage axially, resulting in transmission failure. By setting the stop part 190 to limit the axial movement between the first gear 140 and the second gear 150, the transmission stability of the first gear 140 and the second gear 150 can be ensured, and the reliability can be improved.

[0073] For example, the stop portion 190 may be a baffle. Specifically, the baffle may be provided with a first baffle 191 and a second baffle 192. The first baffle 191 may be disposed on the side of the first gear 140 away from the second gear 150. When the first gear 140 and the second gear 150 are meshed, the first baffle 191 can restrict the axial movement of the second gear 150 towards the first gear 140. The second baffle 192 may be disposed on the side of the second gear 150 away from the first gear 140. When the first gear 140 and the second gear 150 are meshed, the second baffle 192 can restrict the axial movement of the first gear 140 towards the second gear 150. Through the cooperation of the first baffle 191 and the second baffle 192, stable meshing of the first gear 140 and the second gear 150 can be ensured, axial movement can be avoided, and reliability can be improved.

[0074] For example, the first baffle 191 and the second baffle 192 can be disposed on both sides of the first gear 140. The first baffle 191, the second baffle 192, and the teeth of the first gear 140 can be arranged to form multiple slots, and the teeth of the second gear 150 can be inserted into the slots and mesh with the teeth of the first gear 140. Alternatively, the first baffle 191 and the second baffle 192 can be disposed on both sides of the second gear 150. The first baffle 191, the second baffle 192, and the teeth of the second gear 150 can be arranged to form multiple slots, and the teeth of the first gear 140 can be inserted into the slots and mesh with the teeth of the second gear 150. This arrangement can prevent the first gear 140 and the second gear 150 from axially moving during meshing, ensuring stable meshing of the first gear 140 and the second gear 150 and improving transmission reliability.

[0075] In some examples, the aforementioned hanging shaft portion 120 and the aforementioned cover portion 130 are integral structures; and / or the aforementioned hanging shaft portion 120 and the aforementioned first gear 140 are integral structures.

[0076] It is understandable that the lifting shaft portion 120 and the cover portion 130 can be machined into an integral structure through casting or other processing methods. This improves the structural strength of the connection between the lifting shaft portion 120 and the cover portion 130, ensuring that the lifting shaft portion 120 can stably drive the cover portion 130 to rotate, thus improving reliability. Simultaneously, the first gear 140 can be detachably connected to the lifting shaft portion 120. After connecting the first gear 140 to the lifting shaft portion 120, the second gear 150 is driven to rotate by the operating drive unit. The second gear 150 can then drive the first gear 140 to rotate, thereby driving the lifting shaft portion 120 to rotate. Alternatively, the lifting shaft portion 120 and the first gear 140 can be machined into an integral structure through injection molding or other processing methods. This improves the structural strength of the connection between the lifting shaft portion 120 and the first gear 140, ensuring that the first gear 140 can stably drive the lifting shaft portion 120 to rotate, thus improving reliability. Meanwhile, the hanging shaft portion 120 can be detachably connected to the cover portion 130. After the hanging shaft portion 120 is connected to the cover portion 130, the second gear 150 is driven to rotate by the operating drive unit. The second gear 150 can drive the first gear 140 to rotate, thereby driving the hanging shaft portion 120 to rotate through the first gear 140. Alternatively, the hanging shaft portion 120 and the cover portion 130 can be integrated into one structure, while the hanging shaft portion 120 and the first gear 140 can also be integrated into one structure, improving the connection strength at the connection points between the hanging shaft portion 120 and the first gear 140, as well as between the hanging shaft portion 120 and the cover portion 130, thus improving reliability.

[0077] According to a second aspect of the present disclosure, a cooking appliance is provided, comprising: a pot lid assembly 100 as described in any of the above technical solutions.

[0078] It is understood that since the cooking appliance is equipped with the aforementioned lid assembly 100, it possesses all the beneficial effects of the aforementioned lid assembly 100, which will not be elaborated further here. The cooking appliance may also be equipped with a pot body, in which a cooking space is formed. The lid portion 130 of the lid assembly 100 is used to lock onto the pot body. The lid portion 130 may be provided with a latch, and the corresponding pot body may be provided with a locking tooth. After the lid assembly 100 is placed on the pot body in the indicated initial position, the user can operate the drive unit to rotate the second gear 150 in the first rotation direction. The second gear 150 drives the first gear 140 to rotate, and the first gear 140 drives the hanging shaft portion 120 to rotate. Thus, the hanging shaft portion 120 drives the lid portion 130 to rotate relative to the pot body, so that the latch is screwed onto the locking tooth, thereby locking the lid portion 130 onto the pot body, sealing the cooking space, and ensuring that the cooking space is in a high-pressure environment. When the cooking space needs to be opened, the user can operate the drive unit to rotate the second gear 150 in the second rotation direction. The second gear 150 drives the first gear 140 to rotate, and the first gear 140 drives the hanging shaft 120 to rotate. This, in turn, causes the lid 130 to rotate relative to the pot body, thereby disengaging the latch and locking teeth, and unlocking the lid 130 from the pot body. The first and second rotation directions are opposite.
