[0052] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0053] like Figures 1 to 9As shown, according to the first aspect of an embodiment of the present disclosure, a pot cover assembly 100 is proposed, comprising: a first cover body portion 110, having a connecting side and an operating side 1101; a second cover body portion 120, rotatably disposed on the connecting side, for covering or opening the pot mouth; an operating portion 130, detachably disposed on the operating side 1101, and the operating portion 130 is used to apply a magnetic force to the second cover body portion 120 to drive the second cover body portion 120 to rotate.

[0054] The pot cover assembly 100 provided in the embodiment of the present disclosure includes a first cover portion 110, a second cover portion 120 and an operating portion 130, wherein the second cover portion 120 is arranged on the connection side of the first cover portion 110, and in actual application, the second cover portion 120 can be used to cover or open the pot mouth, and the first cover portion 110 can provide structural protection for the second cover portion 120 to reduce the risk of damage to the second cover portion 120, and the second cover portion 120 can be rotated relative to the first cover portion 110, so that in actual application, the second cover portion 120 can be rotated to align the locking structure with the pot body assembly 200, so as to facilitate the locking and unlocking between the second cover portion 120 and the pot body assembly 200.

[0055] The operating portion 130 is used to apply a magnetic force to the second cover portion 120 to rotate it relative to the first cover portion 110, and the operating portion 130 is arranged on the operating side 1101 and can be separated from the operating side 1101. Therefore, in actual application, on the one hand, it is convenient for the user to use the magnetic force of the operating portion 130 to drive the second cover portion 120 to rotate, so as to lock or unlock the pot cover assembly 100 relative to the pot body assembly 200. While facilitating user operation, the operating portion 130 does not need to be in rigid contact with the second cover portion 120, thereby reducing the risk of wear or structural damage between the operating portion 130 and the second cover portion 120, and is conducive to improving the rotation smoothness of the second cover portion 120 and reducing the probability of the second cover portion 120 getting stuck during the rotation process; on the other hand, the rate of the operating portion 130 can be greatly reduced. The transmission component between the pot cover assembly 100 and the second cover body 120 can reduce the number of parts and the overall volume of the pot cover assembly 100, which is beneficial to improving the miniaturization and lightweight level of the pot cover assembly 100 and the pressure cooking appliance; on the other hand, based on the detachable setting of the operating part 130, it can be convenient to use and store the operating part 130 in actual applications. For example, when performing the locking or unlocking operation of the pot cover assembly 100, the operating part 130 can be close to or placed on the operating side 1101 so that the operating part 130 can apply magnetic force to the second cover body 120. When there is no need to lock or unlock the pot cover assembly 100, the operating part 130 can be placed on the operating side 1101 for subsequent use by the user, or the operating part 130 can be removed from the operating side 1101 and stored independently, which is beneficial to improving the aesthetics of the pot cover assembly 100.

[0056] It can be understood that the connection side of the first cover body 110, that is, the side of the first cover body 110 that is used to face the pot mouth in actual application, so that the second cover body 120 is arranged on the aforementioned connection side, which can facilitate the second cover body 120 to cover the pot mouth, and the second cover body 120 can be located between the pot body assembly 200 and the first cover body 110, so as to provide reliable structural protection for the second cover body 120; the aforementioned connection side and the aforementioned operating side 1101 are different sides of the first cover body 110. In actual application, the aforementioned operating side 1101 can be the outer side of the first cover body 110, so that the operating side 1101 can be exposed to the external environment, so that the user can operate the pot cover assembly 100 through the operating side 1101. For example, the operating side 1101 can be the side of the first cover body 110 that is away from the pot mouth when the second cover body 120 covers the pot mouth, or the outer peripheral side distributed around the pot mouth when the second cover body 120 covers the pot mouth.

[0057] For example, Figure 1 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 As shown, the first cover 110 may be a hood-shaped structure, and accordingly, the connection side may be the inner side of the first cover 110, so that when the second cover 120 covers the pot mouth, the first cover 110 may cooperate with the pot assembly 200 to surround the second cover 120, so as to further improve the sealing performance of the pressure cooking device. It should be noted that, in order to facilitate the illustration of the structure of the second cover 120, Figure 2 , Figure 3 , Figure 6 and Figure 8 The first cover portion 110 is hidden in the figure. It is not difficult to understand that, in practical applications, at least part of the first cover portion 110 is located on the side of the second cover portion 120 away from the pot mouth.

[0058] It is understandable that the magnetic force applied by the operating portion 130 to the second cover portion 120 may be a magnetic force in the form of attraction or a magnetic force in the form of repulsion, as long as it can drive the second cover portion 120 to rotate, and no further limitation is made here.

[0059] It is understandable that the pot cover assembly 100 provided in the embodiment of the present disclosure can be used to be set in the pot body assembly 200 of the pressure cooking device or used as a component of the pressure cooking device in actual application, and accordingly, the second cover body portion 120 can be used to cover the pot mouth of the pot body assembly 200 of the pressure cooking device. The pressure cooking device can be, but is not limited to, a pressure cooker, a pressure cooker, etc.

[0060] It should be noted that the lid and pot of the pressure cooking device are usually matched with each other by a locking mechanism. During the pressure cooking process, the lid can be locked to the pot to ensure the pressure stability of the cooking environment. Among them, the screw-on pressure cooker is widely used. The lid and pot of the screw-on pressure cooker are both formed with locking teeth. When the lid covers the pot mouth, the user can adjust the corresponding relationship between the pot body locking teeth and the lid body locking teeth by rotating the lid. When the pot body locking teeth and the lid body locking teeth are aligned, the lid is locked to the pot body. Correspondingly, when the pot body locking teeth and the lid body locking teeth are misaligned, the lid can be separated from the pot body. Similarly, the second cover body portion 120 of the pot cover assembly 100 provided in the present disclosure can also be formed with a locking tooth structure 1211 for locking the pot body assembly 200. Correspondingly, based on the above-mentioned setting of the pot cover assembly 100, the second cover body portion 120 can be rotated under the drive of the operating portion 130 to achieve locking or unlocking with the pot body assembly 200.

[0061] It should be noted that, in the conventional technology, in order to facilitate the user to perform the locking operation of the cover, some screw-on pressure cookers are provided with a handpiece located on the outside of the cover, and one or more transmission components are usually provided between the handpiece and the cover, so that the user can drive the cover to rotate by moving the handpiece. However, the aforementioned arrangement, on the one hand, will lead to an increase in the number of components, thereby increasing the overall volume and weight of the screw-on pressure cooker; on the other hand, the transmission between the handpiece and the cover is carried out by a mechanical mechanism, which is also prone to wear or structural damage in actual application, and the probability of structural jamming will increase, which is not conducive to improving the user's operating convenience, and will also increase the repair and maintenance costs of the product.

[0062] Compared with the aforementioned conventional technology, the pot cover assembly 100 provided in the embodiment of the present disclosure is based on the aforementioned setting. On the one hand, in actual applications, the second cover body 120 can be driven to rotate by a non-contact magnetic drive method, which is beneficial to reduce the risk of wear or structural damage between the operating part 130 and the second cover body 120 while facilitating user operation, and improves the rotation smoothness of the second cover body 120, and reduces the probability of the second cover body 120 getting stuck during rotation; on the other hand, the transmission components between the operating part 130 and the second cover body 120 can be greatly reduced, and the number of components and the overall volume of the pot cover assembly 100 can be reduced, which is beneficial to improving the miniaturization and lightweight level of the pot cover assembly 100 and the pressure cooking appliance.

[0063] like Figure 2 , Figure 3 and Figure 6As shown, in some examples, the second cover body portion 120 includes: a cover body 121, rotatably disposed on the connection side; a mating piece 122, disposed on the cover body 121, a gap is formed between the mating piece 122 and the rotating axis of the cover body 121, and the operating part 130 is used to apply magnetic force to the mating piece 122.

[0064] In this technical solution, the aforementioned second cover body portion 120 may include a cover body 121 and a matching piece 122, wherein the cover body 121 is arranged on the connecting side and can rotate relative to the first cover body portion 110. In actual application, the cover body 121 can be used as the active part of the second cover body portion 120 and is used to cover or open the pot mouth. Accordingly, the pot cover assembly 100 can be locked to the pot body assembly 200 through the cover body 121 to maintain pressure stability during pressure cooking; the matching piece 122 is arranged on the cover body 121, and the aforementioned operating part 130 can be used to apply a magnetic force to the matching piece 122 to drive the cover body 121 to rotate through the matching piece 122, and a gap is formed between the matching piece 122 and the rotating shaft of the cover body 121, that is, there is a radial spacing between the matching piece 122 and the rotating shaft axis of the cover body 121, so that the aforementioned magnetic force can form a torque to drive the cover body 121 to rotate, which is beneficial to further improve the driving convenience and driving efficiency.

[0065] In some examples, one of the operating portion 130 and the fitting 122 includes a magnet, and at least a portion of the other is made of a ferromagnetic material; or both the operating portion 130 and the fitting 122 include a magnet.

[0066] In this technical solution, it can be arranged that one of the operating portion 130 and the matching piece 122 may include a magnet, and the other may be at least partially made of a ferromagnetic material. For example, the operating portion 130 may include a magnet, so that the operating portion 130 may radiate a magnetic field to the outside. Accordingly, at least a portion of the matching piece 122 may be made of a ferromagnetic material, so that the portion of the matching piece 122 made of the ferromagnetic material may be magnetized under the influence of the magnetic field applied by the operating portion 130, and may be acted upon by the magnetic force applied by the operating portion 130, so that the matching piece 122 moves under the magnetic force of the operating portion 130, thereby driving the cover body 121 to rotate, thereby realizing the unlocking or locking of the pot cover assembly 100. Alternatively, at least a portion of the operating portion 130 may be made of ferromagnetic material, so that the portion of the operating portion 130 made of ferromagnetic material is easily magnetized under the influence of an external magnetic field. Accordingly, the fitting 122 may include a magnet, so that the fitting 122 can radiate a magnetic field to the outside. Based on the aforementioned arrangement, when the operating portion 130 is close to the fitting 122, the portion of the operating portion 130 made of ferromagnetic material can be magnetized under the influence of the magnetic field applied by the fitting 122, and generate a magnetic force on the fitting 122, so that the fitting 122 can move under the magnetic force of the operating portion 130, thereby driving the lid body 121 to rotate, thereby realizing the unlocking or locking of the pot cover assembly 100.

[0067] Alternatively, in this technical solution, the operating part 130 and the mating part 122 can both include magnets, so that the operating part 130 and the mating part 122 can radiate magnetic fields to the outside, and then when the operating part 130 is close to the mating part 122, the operating part 130 can apply suction or repulsion to the mating part 122 to drive the mating part 122 to drive the cover body to rotate, and it is beneficial to improve the magnetic field strength between the operating part 130 and the mating part 122, thereby enhancing the stability of the driving process.

[0068] It is understandable that the aforementioned ferromagnetic material may be but is not limited to iron-chromium-cobalt, aluminum-nickel-cobalt, neodymium-iron-boron, etc.; the aforementioned magnet may be but is not limited to a permanent magnet, such as an alloy permanent magnet, a ferrite permanent magnet, etc.

[0069] In some examples, when the fitting member 122 includes a magnet, the spacing direction between the opposite magnetic poles of the magnet of the fitting member 122 is inclined or perpendicular to the rotation axis direction of the cover body 121 .

[0070] In this technical solution, the spacing direction between the opposite poles of the magnet included in the mating piece 122 can be set to be inclined or perpendicular to the rotation axis direction of the cover body 121. Based on the above setting, the direction of the strong magnetic force generated between the operating part 130 and the mating piece 122 can be correspondingly inclined or perpendicular to the rotation axis direction of the cover body 121, and then the above magnetic force can generate a tangential component of the above rotation axis, so as to increase the torque applied by the operating part 130 to the second cover body part 120, further improve the convenience and driving efficiency of the operating part 130 when driving the second cover body part 120 to rotate, and help improve the rotation smoothness of the second cover body part 120.

[0071] It can be understood that the opposite poles of the aforementioned magnet are the N pole and S pole of the magnet. Accordingly, the magnetic poles of the magnet are usually the parts with the strongest magnetism. When the magnetic poles of the operating part 130 correspond to the magnetic poles of the matching part 122, the magnetic force generated by the operating part 130 on the matching part 122 is the strongest. Based on the aforementioned setting of the technical solution, when the magnetic force generated by the operating part 130 on the matching part 122 is the strongest, the direction of the magnetic force will have a tangential component in the direction of the cover body shaft, which is beneficial to increase the torque applied by the operating part 130 on the second cover body 120.

[0072] like Figure 2 and Figure 3 As shown, in some examples, the mating piece 122 includes: a base 1221, which is arranged on the cover body 121, and a gap is formed between the base 1221 and the rotating shaft of the cover body 121; a pressure cover 1222, which is arranged on the base 1221, and the pressure cover 1222 and the base 1221 together form an installation cavity; a mating body 1223, which is arranged in the installation cavity, and the operating part 130 is used to apply magnetic force to the mating body 1223; wherein the mating body 1223 is a magnet or is made of ferromagnetic material.

[0073] In this technical solution, the aforementioned matching piece 122 may include a base 1221, a pressure cover 1222 and a matching body 1223, wherein the matching body 1223 is a magnet or is made of a ferromagnetic material, so that the matching body 1223 is easily affected by the magnetic force applied by the operating part 130, so as to move under the magnetic force of the operating part 130; the base 1221 is arranged on the cover body 121 and forms a gap with the rotating shaft of the cover body 121, the pressure cover 1222 and the base 1221 are surrounded by a mounting cavity, and the aforementioned matching body 1223 is arranged in the aforementioned mounting cavity, so that based on the aforementioned arrangement On the one hand, there can be a radial spacing between the axis of the rotating shaft of the mating body 1223 and the cover body 121, so that the magnetic force applied to the mating body 1223 by the operating part 130 can form a torque to drive the cover body 121 to rotate, which is beneficial to further improve the driving convenience and driving efficiency; on the other hand, the mating body 1223 can maintain a relatively stable relative position relationship with the cover body 121 under the constraints of the base 1221 and the pressure cover 1222, thereby avoiding the movement of the mating body 1223 relative to the cover body 121, which is beneficial to ensure the smooth progress of the driving process.

[0074] In some feasible examples, the pressure cover 1222 is detachably disposed on the base 1221 , so as to facilitate opening the aforementioned installation cavity in actual application, and further facilitate maintenance or replacement of the matching part 122 , which is beneficial to reducing the use cost of the pot cover assembly 100 .

[0075] like Figure 3 As shown, in some examples, the base 1221 and the cover body 121 are an integral structure.

[0076] In this technical solution, the base 1221 and the cover body 121 can be set as an integrated structure, so as to further improve the connection strength between the base 1221 and the cover body 121, which is beneficial to reduce the probability of the base 1221 detaching from or moving relative to the cover body 121, providing further guarantee for the smooth progress of the driving process, and facilitating the processing of the base 1221 and the cover body 121 by integrated molding in the process of manufacturing the pot cover assembly 100, which is beneficial to improve the processing convenience and processing efficiency of the pot cover assembly 100, and save the processing cost of the pot cover assembly 100.

[0077] like Figure 4 and Figure 5As shown, in some examples, the pot cover assembly 100 also includes: a first identification portion 140, which is arranged on the operating side 1101, and the mating piece 122 has a locking position and an unlocking position along the rotation direction of the cover body 121, and the first identification portion 140 is arranged corresponding to the locking position; a second identification portion 150, which is arranged on the operating side 1101, and the second identification portion 150 is arranged corresponding to the unlocking position; wherein, when the mating piece 122 is in the locking position, the second cover body portion 120 is used to lock at the pot mouth; when the mating piece 122 is in the unlocking position, the second cover body portion 120 is used to be detachably arranged at the pot mouth.

[0078] In this technical solution, the aforementioned pot cover assembly 100 may also include a first identification portion 140 and a second identification portion 150 arranged on the aforementioned operating side 1101, wherein the first identification portion 140 is arranged corresponding to the locked position of the matching piece 122, and the second identification portion 150 is arranged corresponding to the unlocked position of the matching piece 122. It can be understood that in the process of using the operating portion 130 to drive the matching piece 122 to move, considering the stability of the magnetic force between the operating portion 130 and the matching piece 122, the operating portion 130 can drive the matching piece 122 by moving relative to the first cover body portion 110. The mating piece 122 moves, so that during the driving process, the relative position between the operating part 130 and the mating piece 122 can be in a relatively stable state, thereby maintaining the stability of the aforementioned magnetic force; based on the aforementioned setting of the technical solution, during the movement of the operating part 130 on the operating side 1101, the pot cover assembly 100 can use the relative position between the operating part 130 and the first identification part 140 or the second identification part 150 to more intuitively prompt the user of the position of the mating piece 122, so as to further improve the user's convenience during operation and improve the user experience of the product.

[0079] It can be understood that the aforementioned locking position and unlocking position are also the angular positions of the fitting 122 relative to the rotation axis of the cover body 121 . In combination with the above, taking the case where the pot cover assembly 100 is applied to a screw-on pressure cooker as an example, the aforementioned locking position, i.e., when the second cover body 120 covers the pot mouth, the locking tooth structure 1211 of the second cover body 120 corresponds to the locking tooth structure of the pot body assembly 200, and when the matching piece 122 is in the locking position, the second cover body 120 can be locked at the pot mouth of the pot body assembly 200; the aforementioned unlocking position, i.e., when the second cover body 120 covers the pot mouth, the locking tooth structure 1211 of the second cover body 120 is misaligned with the locking tooth structure of the pot body assembly 200, and when the matching piece 122 is in the unlocking position, the locking relationship between the second cover body 120 and the pot body assembly 200 is released, and accordingly, the second cover body 120 can be separated from the pot mouth of the pot body assembly 200.

[0080] It can be understood that the structural forms of the first identification part 140 and the second identification part 150 can be stickers, coatings, raised structures, recessed structures, etc.; and the first identification part 140 and the second identification part 150 can respectively indicate the aforementioned locking position and unlocking position through their respective structural appearances. For example, the structural appearances of the first identification part 140 and the second identification part 150 can be in the form of words, letters, graphics, etc. There are no excessive limitations on the structural forms and structural appearances of the first identification part 140 and the second identification part 150. Exemplarily, as Figure 5 shown, the structural appearance of the first identification part 140 can be the Chinese character "lock" to indicate the locking position, and the structural appearance of the second identification part 150 can be the Chinese character "open" to indicate the unlocking position.

[0081] It should be noted that Figure 4 and Figure 5 only schematically show some feasible structural appearances of the first identification part 140 and the second identification part 150 in actual applications. In addition, there can be various structural appearances of the first identification part 140 and the second identification part 150, and there is no excessive enumeration and limitation here.

[0082] Such as Figure 4 and Figure 5 shown, in some examples, the pot lid assembly 100 further includes: a third identification part 160, arranged on the operation side 1101, the third identification part 160 is located between the first identification part 140 and the second identification part 150, and the extending direction of the third identification part 160 is consistent with the rotation direction of the lid body 121; wherein, when the fitting 122 is located between the locking position and the unlocking position, the orthographic projection of the fitting 122 on the operation side 1101 and the orthographic projection of the third identification part 160 on the operation side 1101 at least partially overlap.

[0083] In this technical solution, the aforementioned pot cover assembly 100 may further include a third identification portion 160 arranged on the operating side 1101, the third identification portion 160 is located between the first identification portion 140 and the second identification portion 150 and may extend in an arc shape, and accordingly, the extension direction of the third identification portion 160 may be set to be consistent with the rotation direction of the cover body 121, so that based on the aforementioned setting, when the user uses the operating portion 130 to drive the matching member 122, the pot cover assembly 100 may further prompt the user with the moving direction of the operating portion 130 through the third identification portion 160, which is conducive to further improving the pot cover. The operating convenience of the component 100; at the same time, it can be arranged that when the fitting 122 is located between the locked position and the unlocked position, the orthographic projection of the fitting 122 on the operating side 1101 and the orthographic projection of the third identification portion 160 on the operating side 1101 at least partially overlap, thereby further improving the matching degree between the moving range of the fitting 122 and the distribution range of the third identification portion 160, so that when the operating portion 130 is located within the distribution range of the third identification portion 160, it is more reliably and stably to apply magnetic force to the fitting 122, which is conducive to further improving the reliability of the pot cover assembly 100.

[0084] It is understandable that the third identification portion 160 may be in the form of a sticker, a coating, a convex structure or a concave structure, etc., and the third identification portion 160 may be in an arc shape, for example, the orthographic projection of the third identification portion 160 on the operating side 1101 may be an arc line, an arc shape, etc. The structural form and structural appearance of the third identification portion 160 are not limited too much here.

[0085] It should be noted that Figure 4 and Figure 5 The figure only schematically shows some feasible structural appearances of the third identification portion 160 in practical applications. In addition, the structural appearances of the third identification portion 160 can be various, which will not be listed or limited in detail here.

[0086] In some examples, the pot cover assembly 100 further includes: a driving portion connected to the second cover portion 120 and configured to drive the second cover portion 120 to rotate.

[0087] In this technical solution, the pot lid assembly 100 may also include a driving portion connected to the second cover body portion 120, and the driving portion is used to drive the second cover body portion 120 to rotate. Based on the above-mentioned arrangement, if the operating portion 130 is unable to drive the second cover body portion 120 in actual application, the pot lid assembly 100 can further utilize the driving portion to unlock or lock the pot lid assembly 100, which is beneficial to further improve the reliability of the pot lid assembly 100 and improve the user experience of the product.

[0088] It can be understood that the aforementioned driving unit can be, but is not limited to, a driving device such as an electric motor or an electric motor.

[0089] It can be understood that, in actual applications, based on the settings of the aforementioned driving portion and the aforementioned operating portion 130, there can be two ways to drive the second cover body portion 120 to rotate, that is, the user can manually drive the second cover body portion 120 to rotate using the operating portion 130, or the driving portion can drive the second cover body portion 120 to rotate, so that when one of the aforementioned two driving methods fails, the pot cover assembly 100 can drive the second cover body portion 120 to rotate in another way, thereby enhancing the reliability of the pot cover assembly 100 during use.

[0090] like Figures 7 to 9 As shown, according to the second aspect of the embodiment of the present disclosure, a pressure cooking device is proposed, including: a pot body assembly 200, which is formed with a pot mouth; and a pot cover assembly 100 as proposed in any one of the first aspects above, which is used to cover or open the pot mouth.

[0091] The pressure cooking device provided by the embodiment of the present disclosure includes a pot body assembly 200 and a pot cover assembly 100 as proposed in any one of the first aspects above, wherein the pot body assembly 200 is formed with a pot mouth, and the second cover body portion 120 of the pot cover assembly 100 is used to cover or open the pot mouth. It can be understood that both the second cover body portion 120 and the pot body assembly 200 can be formed with a locking tooth structure. When the second cover body portion 120 covers the aforementioned pot mouth, the second cover body portion 120 can adjust the corresponding relationship between the locking tooth structure 1211 of the second cover body portion 120 and the locking tooth structure of the pot body assembly 200 by rotating, so as to achieve locking or unlocking between the pot cover assembly 100 and the pot body assembly 200. At the same time, based on the above-mentioned arrangement of the pot cover assembly 100, it is convenient for the user to utilize the operating portion 130 to magnetically drive the second cover body portion 120 to rotate, so as to perform a locking or unlocking operation of the pot cover assembly 100 relative to the pot body assembly 200. While facilitating the user's operation, the operating portion 130 does not need to be in rigid contact with the second cover body portion 120, thereby reducing the risk of wear or structural damage between the operating portion 130 and the second cover body portion 120, and is conducive to improving the rotation smoothness of the second cover body portion 120, and reducing the probability of the second cover body portion 120 getting stuck during the rotation process; on the other hand, the transmission components between the operating portion 130 and the second cover body portion 120 can be greatly reduced, which can reduce the number of components and the overall size of the pot cover assembly 100. On the other hand, based on the detachable setting of the operating part 130, the use and storage of the operating part 130 in practical applications can be facilitated. For example, when performing the locking or unlocking operation of the pot cover assembly 100, the operating part 130 can be close to or placed on the operating side 1101, so that the operating part 130 can apply magnetic force to the second cover body part 120. When there is no need to lock or unlock the pot cover assembly 100, the operating part 130 can be placed on the operating side 1101 for subsequent use by the user, or the operating part 130 can be removed from the operating side 1101 and stored independently, which is beneficial to improving the aesthetics of the pot cover assembly 100 and the pressure cooking appliance.

[0092] It can be understood that the pressure cooking device provided in the embodiment of the present disclosure can be used as a cooking device such as a pressure cooker or a pressure kettle in practical applications.

[0093] In addition, since the pressure cooking device provided by the embodiment of the present disclosure includes the pot cover assembly 100 as proposed in any one of the first aspects above, it has all the beneficial effects of the pot cover assembly 100, which will not be elaborated here.
