Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to a pressure cooking appliance. Background Art

[0002] In order to ensure pressure cooking in a safe environment, a pressure cooking appliance (such as a pressure cooker) needs to lock the lid to the pot body. In the prior art, the lid teeth on the lid are generally locked with the pot teeth on the pot body, or the lid teeth and the pot teeth are unlocked by horizontal rotation of the lid.

[0003] In order to facilitate the user to operate the pot cover, the pot cover is often provided with a handle. The handle on the pot cover of the existing pressure cooking device is generally located in the center of the pot cover. When the user rotates the pot cover by the handle, since the handle is located at the rotation center of the pot cover, it is very laborious to rotate and is relatively inconvenient to use.

[0004] To address this issue, some pressure cooking appliances have the handle eccentrically positioned on the lid, for example, on the edge of the lid. This handle arrangement increases the lever arm of the handle, making rotation more labor-efficient. However, when rotating at the same angle, the further outward the lid is, the longer the arc length, that is, the path of the handle, becomes. This results in a greater positional change before and after the handle is rotated. This not only makes it easier for the handle to interfere with other objects in a small space, but also gradually increases the user's range of motion, making operation and use less convenient.

[0005] In addition, this operating method is more flexible and difficult to control, and the center of rotation of the handle may change, thereby affecting the smoothness and stability of the operation. Utility Model Content

[0006] The present application provides a pressure cooking appliance to solve the problems that the handle is laborious to rotate, has a large movement path, undergoes large position changes before and after rotation, and is difficult to control, resulting in inconvenience in use.

[0007] The technical solutions adopted in this application are:

[0008] A pressure cooking appliance comprises a pot body and a pot lid, wherein the pot lid is provided with cover teeth and the pot body is provided with pot teeth; the pot lid comprises an inner lid and a lid body located outside the inner lid, and the inner lid can be rotated relative to the lid body to unlock or lock the cover teeth and the pot teeth; the pot lid also comprises an operating handle arranged on the top surface of the lid body, the operating handle is used to drive the inner lid to rotate, the operating handle has a rotating ring and a gripping portion, the gripping portion extends from the rotating ring to the edge of the pot lid so as to be suspended above the pot lid; the rotating ring is concentrically arranged with the inner lid, and the gripping portion is eccentrically arranged with respect to the inner lid, the lower end of the rotating ring is provided with a step portion and a fixing platform, the lower end of the fixing platform is fixed to the inner lid to drive the inner lid to rotate, and the step portion cooperates with the lid body to form a rotation limit.

[0009] The pressure cooking device of the present application also has the following additional technical features:

[0010] The pressure cooking appliance further comprises a pressure relief valve arranged at the center of the pot cover, an exhaust valve cover is arranged in the rotating ring, the exhaust valve cover covers the pressure relief valve, and the exhaust valve cover rotates synchronously with the rotating ring.

[0011] The fixing platform is sunken to form an accommodating sink, and at least a part of the pressure relief valve is located in the accommodating sink.

[0012] The lower end of the rotating ring is provided with a bottom wall, and the bottom wall is provided with a mounting hole for the pressure relief valve to pass through. The pressure cooking appliance further comprises a sealing member located between the pressure relief valve and the mounting hole to seal the mounting hole.

[0013] An escape opening is provided at the center of the cover body, the fixing platform passes through the escape opening, and the step portion comprises a convex rib protruding outwardly along the radial direction of the rotating ring, and the convex rib is placed above the edge of the escape opening.

[0014] The pot cover has a connecting end which is rotatably connected to the pot body so that the pot cover can be turned over relative to the pot body to open or close the pot body, and the gripping portion is located on a side of the rotating ring away from the connecting end.

[0015] The top surface of the cover body is provided with a convex structure, which is located on the side of the rotating ring close to the connecting end. The side of the convex structure facing the operating handle is provided with a guide arc surface, and the outer peripheral side of the rotating ring cooperates with the guide arc surface.

[0016] The top surface of the cover body is provided with a convex structure, the convex structure is located on one side of the rotating ring, and a cooling fan is provided in the convex structure.

[0017] The gripping portion extends upwardly and obliquely relative to the rotating ring, so that a gripping gap is formed between the gripping portion and the top surface of the cover body.

[0018] The operating handle includes a handle seat and a handle cover. The fixing platform is arranged on the handle seat. The center of the cover body is provided with an avoidance opening. The center of the inner cover is provided with a fixing part which is fixedly connected to the fixing platform. The handle cover covers the handle seat.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] 1. In this application, the operating handle is used to drive the inner lid to rotate horizontally relative to the lid body to unlock or lock it with the pot body. The operating handle includes a rotating ring and a grip portion. The grip portion extends from the rotating ring toward the edge of the pot lid, suspended above the pot lid. The extended grip portion allows the entire operating handle to be controlled by manipulating it. The rotating ring is concentric with the inner lid, while the grip portion is eccentric with the inner lid. Therefore, when the user rotates the operating handle using the grip portion, the operating handle rotates about the center of the rotating ring, i.e., the center of the inner lid. This ensures that the rotation center of the operating handle is located within the operating handle itself. Consequently, the operating handle's movement is a swing of the grip portion about the rotating ring, while the rotating ring remains in position, rotating in place. The operating handle as a whole does not experience significant positional changes. This reduces the space occupied by the operating handle during movement, as well as the user's operating space. This facilitates pot lid operation in confined spaces and enhances the user experience. Furthermore, the eccentricity of the grip portion with the inner lid increases the moment arm between the user's operating position and the rotation center, making operation more labor-efficient.

[0021] In addition, the fixed platform below the rotating ring is fixedly connected to the inner cover, and the stepped portion cooperates with the cover body to limit rotation, so that the rotation center of the operating handle is always located at the center of the rotating ring, that is, the center of the inner cover, thereby greatly improving the rotation stability and reliability of the operating handle. Furthermore, the rotating ring is fixedly connected to the inner cover. When the operating handle drives the inner cover to rotate, the rotation limit of the inner cover is formed by the rotation limit of the stepped portion and the cover body, further improving the rotation limit effect of the inner cover, making the movement of the inner cover more stable, and improving the limit of the inner cover, which helps to reduce shaking during the opening and closing of the cover and during the rotation of the inner cover.

[0022] 2. As a preferred embodiment of the present application, the pressure relief valve is arranged at the center of the pot lid and passes through the rotating ring. This not only makes the pressure relief valve located at the rotation center of the inner lid, but also during the rotation of the inner lid, the pressure relief valve rotates in place and does not change its position relative to the lid body, thereby greatly reducing the difficulty of sealing between the pressure relief valve and the lid body. In addition, an integrated design of the pressure relief valve and the operating handle is also implemented, so that the functional components on the pot lid are arranged more centrally, thereby freeing up space on the top surface of the pot lid and making the appearance of the pot lid more simple and beautiful. The exhaust valve cover is provided with an exhaust port, and the exhaust valve cover will rotate with the rotation of the rotating ring. Therefore, no matter which position the operating handle is rotated to, the relative position of the exhaust port and the grip portion always remains consistent, so that the grip position and the exhaust position remain relatively fixed, greatly reducing the risk of burns during user operation and improving the user experience.

[0023] 3. As a preferred embodiment of the present application, the lower end of the rotating ring has a bottom wall, which defines a mounting hole for the pressure relief valve. The pressure cooking appliance further includes a sealing member positioned between the pressure relief valve and the mounting hole to seal the mounting hole. The arrangement of the bottom wall allows the sealing member to deform due to compression between the pressure relief valve and the bottom wall, thereby sealing the mounting hole and improving the sealing effect of the mounting hole. This prevents gas or liquid from entering the lid through the mounting hole during the venting of the pressure relief valve, thereby ensuring a clean interior of the lid.

[0024] 4. As a preferred embodiment of the present application, the pot lid has a connecting end that is rotatably connected to the pot body, allowing the pot lid to be flipped relative to the pot body to open or close the pot body. The grip is located on the side of the rotating ring away from the connecting end. In addition to operating the handle to lock or unlock the pot lid with the pot body, the user can also operate the handle to flip the pot lid open or close the pot body. The grip is located away from the connecting end, which also increases the lever arm between the grip and the connecting end, thereby reducing the user's effort when opening and closing the pot lid.

[0025] 5. As a preferred embodiment of the present application, the top surface of the lid is provided with a convex structure, which is located on the side of the rotating ring close to the connection end. A guide arc surface is provided on the side of the convex structure facing the operating handle, and the rotating ring cooperates with the guide arc surface. The operating handle is a structure protruding from the top surface of the pot cover, and the convex structure also protrudes from the top surface of the pot cover. The convex structure is located on the side of the operating handle close to the connection end. When the operating handle is not rotated, the convex structure is collinear with the operating handle, thereby reducing the abruptness of the operating handle, optimizing the structural layout of the top surface of the pot cover, and making it more beautiful. In addition, the convex structure has a guide arc surface that cooperates with the rotating ring. When the operating handle rotates around the rotating ring, the guide arc surface can guide the rotating ring, guiding the rotating ring to rotate, thereby improving the smoothness of the rotation of the operating handle and the operating feel.

In the description of this specification, the reference terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" and the like mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0051] like Figure 1 、 Figure 2 、 Figure 8 、 Figure 11As shown, a pressure cooking device includes a pot body 1 and a pot cover 2, the pot cover 2 is provided with a cover tooth 25, the pot body is provided with a pot tooth 11, the pot cover 2 includes an inner cover 22 and a cover body 21 located outside the inner cover 22, the inner cover 22 can be horizontally rotated relative to the cover body 21 to unlock or lock the cover tooth 25 with the pot tooth 11 on the pot body, the pot cover 2 also includes an operating handle 3 arranged on the top surface of the cover body 21, the operating handle 3 is used to drive the inner cover 22 to rotate, the operating handle 3 has a rotating ring 32 and a gripping portion 31, the gripping portion 31 extends from the rotating ring 32 to the edge of the pot cover 2 so as to be suspended above the pot cover, the rotating ring 32 is concentrically arranged with the inner cover 22, the gripping portion 31 is eccentrically arranged relative to the inner cover 22, the lower end of the rotating ring 32 is provided with a step portion 36 and a fixing platform 35, the lower end of the fixing platform 35 is fixed to the inner cover 22 to drive the inner cover 22 to rotate, and the step portion 36 cooperates with the cover body 21 to form a rotation limit.

[0052] It should be noted that the lower side of the inner cover 22 is used to cooperate with the pot body 1 to form a cooking cavity, so the cover body 21 is located outside the inner cover 22, which means that the cover body 21 surrounds the outer periphery of the inner cover 22 and the upper side of the inner cover 22. Preferably, the cover body 21 is made of plastic, while the inner cover 22 needs to withstand high temperature and high pressure and is therefore made of metal.

[0053] In the present application, the operating handle 3 is used to drive the inner cover 22 to rotate horizontally relative to the cover body 21 to unlock or lock it with the pot body 1. The operating handle 3 includes a rotating ring 32 and a gripping portion 31, wherein the rotating ring 32 is concentrically arranged with the inner cover 22, and the gripping portion 31 is eccentrically arranged with the inner cover 22. The gripping portion 31 extends from the rotating ring 32 to the edge of the pot cover 2 to be suspended above the pot cover. The gripping portion 31 is suspended in the space below the pot cover to provide a convenient operating space for the hand to hold, so that the entire operating handle 3 can be controlled by operating the extended gripping portion. Therefore, when the user rotates the operating handle 3 through the gripping portion 31, the operating handle 3 will rotate around the center of the rotating ring 32, that is, the center of the cover body 21. This arrangement allows the center of rotation of the operating handle 3 to be located within the operating handle 3 itself. Consequently, the operating handle 3 moves as the grip portion 31 swings about the rotating ring 32. The rotating ring 32 remains in place, rotating in place. The operating handle 3 as a whole does not experience significant positional changes, saving space occupied by the operating handle 3 during movement and the user's operating space. This facilitates operation of the pot lid 2 in confined spaces and improves the user experience. Furthermore, the eccentricity of the grip portion 31 relative to the inner lid 22 increases the lever arm between the user's operating position and the center of rotation, making operation more labor-efficient.

[0054] Furthermore, the fixed platform 35 below the rotating ring 32 is fixedly connected to the inner cover 22, and the stepped portion 36 cooperates with the cover body 21 to limit the rotation, ensuring that the rotation center of the operating handle 3 is always located at the center of the rotating ring 32, that is, the center of the inner cover 22, thereby greatly improving the rotational stability and reliability of the operating handle 3. Furthermore, the rotating ring 32 is fixedly connected to the inner cover 22, and the movement of the inner cover 22 is also more stable during the process of the operating handle 3 driving the inner cover 22 to rotate, thereby improving the position limit of the inner cover 22 and helping to reduce the shaking that occurs during the opening and closing of the cover and during the rotation of the inner cover 22.

[0055] Specifically, such as Figure 1 As shown, the center of the rotating ring 32 has an annular opening, and at least a portion of the outer circumference is in an arc shape.

[0056] It is understood that the inner cover 22 is circular. In one embodiment, Figure 1 、 Figure 8 As shown, the lid 21 includes a cover plate and a protrusion on one side of the edge of the cover plate for mounting a hinged connection structure with the pot body 1. The center of the lid 21 is the center of the cover plate, so the rotating ring 32 is concentric with the inner lid 22, that is, the central axis of the inner lid 22, the lid 21, the rotating ring 32, and the pressure relief valve 6 coincide. Similarly, the center of the pot lid 2 in this application is also on this central axis.

[0057] As a preferred embodiment of the present application, Figure 8 As shown, the pressure cooking appliance further includes a pressure relief valve 6 arranged at the center of the pot cover 2, and an exhaust valve cover 5 is provided in the rotating ring 32. The exhaust valve cover 5 covers the pressure relief valve 6, and the exhaust valve cover 5 rotates synchronously with the rotating ring 32.

[0058] The pressure relief valve 6 is located at the center of the pot lid 2 and passes through the rotating ring 32. This not only positions the pressure relief valve 6 at the rotation center of the inner lid 22, but also allows the pressure relief valve 6 to rotate in place during the rotation of the inner lid 22 without changing its position relative to the lid 21. This significantly reduces the difficulty of sealing the pressure relief valve 6 with the lid 21. Furthermore, the integrated design of the pressure relief valve 6 and the operating handle 3 allows for a more centralized arrangement of the functional components on the pot lid 2, freeing up space on the top surface of the pot lid 2 and making the pot lid 2 more concise and aesthetically pleasing.

[0059] Furthermore, the pressure relief valve 6 is located at the center of the pot lid 2, i.e., at the rotation center of the inner lid 22. Therefore, the moment arm between the two is zero. Therefore, when the user rotates the inner lid 22 via the operating handle 3, there is no need to bear the weight of the pressure relief valve 6, resulting in less resistance during rotation and greater effort saving. Furthermore, the pressure relief valve 6 being located at the center of the pot lid 2 eliminates the need for a rotation slot in the pot lid 2 for the pressure relief valve 6 to rotate with the inner lid 22, thus saving space.

[0060] Furthermore, if Figures 1 to 5As shown, the exhaust valve cover 5 is provided with an exhaust port 51 .

[0061] The gas discharged by the pressure relief valve 6 can flow out through the exhaust port 51 to ensure the normal use of the exhaust and pressure relief function. Preferably, the exhaust valve cover 5 is detachably fixed to the rotating ring 32 so that the accommodating sink 321 can be opened, making it convenient for the user to clean the interior of the accommodating sink 321.

[0062] The exhaust valve cover 5 will rotate with the rotation of the rotating ring 32, and no matter what position the operating handle 3 is rotated to, the relative position of the exhaust port 51 and the grip portion 31 will always remain consistent, so that the grip position and the exhaust position remain relatively fixed, greatly reducing the risk of users being burned during operation and improving the user experience.

[0063] Preferably, the exhaust valve cover 5 is detachable, and at least one of the exhaust valve cover 5 and the rotating ring 32 is provided with a limiting portion to limit relative rotation between the exhaust valve cover 5 and the rotating ring 32 .

[0064] Furthermore, if Figure 1 As shown, the exhaust port 51 is located on a side away from the grip portion 31. This position keeps the exhaust away from the user's hand, thereby reducing the impact of high-temperature airflow on the user's manipulation of the operating handle 3. This also prevents the high-temperature airflow from being too close to the grip portion 31, which could cause the grip portion 31 to heat up. This keeps the grip portion 31 at a lower temperature, improving the user's grip.

[0065] In other embodiments, the exhaust port 51 is opened at the center of the exhaust valve cover 5 .

[0066] Specifically, such as Figure 2 、 Figure 3 、 Figure 8 As shown, the pressure relief valve 6 includes an exhaust pipe 61 and a weight 62 placed at the top of the exhaust pipe 61. The exhaust pipe 61 passes through the inner cover 22 and is connected to the environment inside the pot. The upper end passes through the outside of the cover body 21 and is blocked by the weight 62.

[0067] Furthermore, if Figure 3 As shown, a mating port 221 is provided at the center of the inner cover 22, and the pressure relief valve 6 passes through the mating port 221. A first sealing ring 71 is provided between the mating port 221 and the pressure relief valve 6. The operating handle 3 can drive the inner cover 22 to drive the pressure relief valve 6 to rotate synchronously.

[0068] The first sealing ring 71 not only seals the gap between the pressure relief valve 6 and the mating opening 221, preventing gas leakage within the pot, but also creates significant frictional resistance when the sealing member 7 is squeezed by the pressure relief valve 6 and the rim of the mating opening 221. Consequently, when the operating handle 3 rotates the inner lid 22, this frictional resistance also causes the pressure relief valve 6 to rotate synchronously. The pressure relief valve 6 rotates around its own axis and does not change position.

[0069] As a preferred embodiment of the present application, Figure 3 As shown, the fixing platform 35 is sunken to form an accommodating groove 321 , and at least a portion of the pressure relief valve 6 is located in the accommodating groove 321 .

[0070] The pressure relief valve 6 is accommodated in the accommodating recess 321, thereby preventing the pressure relief valve 6 from excessively protruding from the operating handle 3, helping to reduce the overall height of the pot cover 2 and achieve a lightweight design. On the other hand, the pressure relief valve 6 can be hidden, improving the aesthetics of the pot cover 2.

[0071] Preferably, if Figure 11 As shown, the lower end of the rotating ring 32 has a bottom wall 322, and the bottom wall 322 is provided with a mounting hole for the pressure relief valve 6 to pass through. The pressure cooking appliance further includes a sealing member 7 located between the pressure relief valve 6 and the mounting hole to seal the mounting hole.

[0072] The bottom wall 322 allows the seal 7 to be squeezed by the pressure relief valve 6 and the bottom wall, thereby deforming and sealing the mounting hole, thereby improving the sealing effect of the mounting hole. This prevents gas or liquid from entering the interior of the cover 21 through the mounting hole during the exhaust process of the pressure relief valve 6, thereby ensuring that the interior of the cover 21 is clean.

[0073] It should be noted that the seal 7 can be arranged between the outer peripheral side of the pressure relief valve 6 and the mounting hole, or can be arranged as shown in FIG. Figure 11 As shown, it is arranged in the accommodating groove 321, fits against the bottom wall 322, and is squeezed by the heavy hammer so as to fit against the bottom wall 322, thereby sealing the installation hole.

[0074] Specifically, the bottom wall 322 is further provided with a plurality of fixing holes, and the sealing member 7 is provided with avoidance holes corresponding to the installation holes and the fixing holes.

[0075] In a preferred embodiment, Figure 11 As shown, a clearance opening 211 is opened in the center of the cover body 21 , and the fixing platform 35 passes through the clearance opening 211 . The step portion 36 includes a rib protruding radially outward along the rotating ring 32 , and the rib is placed above the edge of the clearance opening 211 .

[0076] The rotating ring 32 is securely connected to the inner cover 22 and also engages with the edge of the escape opening 211, providing upward support for the rotating ring 32 and further stabilizing the rotating ring 32. Specifically, a sliding groove can be provided on the upper side of the edge of the escape opening 32, or a stop rib can be provided to define the rotation angle. The rib can also be provided with a mating structure to limit the rotation angle of the rotating ring 32, so that the rotating ring 32 can only rotate within a limited angle.

[0077] It should be noted that the present application does not limit the assembly method of the pot lid 2 and the pot body 1. In one embodiment, the pot lid 2 and the pot body 1 are of a separate structure, and the pot lid 2 can be removed from the pot body 1 to completely open the pot body 1. When closing the lid, the user first places the pot lid 2 on the pot body 1, and then rotates the operating handle 3 to lock the pot lid 2 with the pot body 1.

[0078] In another embodiment, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, the pot cover 2 has a connecting end 24, which is rotatably connected to the pot body 1 so that the pot cover 2 can be flipped relative to the pot body 1 to open or cover the pot body 1, and the gripping portion 31 is located on the side of the rotating ring 32 away from the connecting end 24.

[0079] In this embodiment, the lid 2 and the pot body 1 are integrated. The connection end 24 of the lid 2 is rotatably connected to the pot body 1, allowing the lid 2 to be flipped up and down around the connection end 24 to open and close. In addition to locking and unlocking the lid 2 with the pot body 1 using the handle 3, the user can also flip the lid 2 open or close the pot body 1 using the handle 3 when the lid 2 is unlocked. The grip 31 is positioned away from the connection end 24, which also increases the lever arm between the grip 31 and the connection end 24, thereby reducing the user's effort when opening and closing the lid.

[0080] In addition, since the grip portion 31 and the lid body 21 are eccentrically arranged, when the user flips the pot lid 2 to open it, the user's arm can more easily avoid the pot lid 2 and is not likely to touch the pot lid 2, thereby greatly reducing the risk of the user being scalded during the opening process.

[0081] Specifically, the connection end 24 can be the rear end of the pot lid 2, that is, the end away from the user when in use, and when opening the lid, the pot lid 2 is flipped open from front to back. Of course, the connection end 24 can also be located on one side of the pot lid 2, such as the left or right side, and when opening the lid, the pot lid 2 is flipped open from one side to the other.

[0082] Preferably, if Figure 1 、 Figures 4 to 7 As shown, the top surface of the cover body 21 is provided with a convex structure 4, which is located on the side of the rotating ring 32 close to the connecting end 24. The side of the convex structure 4 facing the operating handle 3 is provided with a guide arc surface, and the rotating ring 32 cooperates with the guide arc surface.

[0083] The operating handle 3 protrudes from the top surface of the pot lid 2. The convex structure 4 also protrudes from the top surface of the pot lid 2. The convex structure 4 is located on the side of the operating handle 3 near the connecting end 24. When the operating handle 3 is not rotated, it is collinear with the operating handle 3, thereby reducing the abruptness of the operating handle 3 and optimizing the structural layout of the pot lid 2, making it more aesthetically pleasing. Furthermore, the convex structure 4 has a guide arc surface that cooperates with the rotating ring 32. When the operating handle 3 rotates around the rotating ring 32, the guide arc surface can guide the rotating ring 32, guiding the rotation of the rotating ring 32, thereby improving the smoothness of the rotation of the operating handle 3 and the operating feel.

[0084] Specifically, such as Figure 4 、 Figure 5 As shown, the side of the rotating ring 32 facing the convex structure 4 is an arc surface. When the rotating ring 32 rotates, it rotates along the guide arc surface. Specifically, the rotating ring 32 can contact the guide arc surface or not, which is not limited here.

[0085] like Figure 1 As shown, the operating handle 3 extends along the radial direction of the pot cover 2, the outer end (the end away from the center of the pot cover 2) constitutes a gripping portion 31, and the inner end (the end located at the center of the pot cover 2) constitutes a rotating ring 32. Figure 4 、 Figure 5 、 Figure 9 As shown, the convex structure 4 extends to the edge of the top surface of the cover 21. Figure 4 As shown, when the operating handle 3 is in the first position, the operating handle 3 and the convex hull structure 4 are collinear, as shown in FIG. Figure 5 As shown, when the operating handle 3 is in the second position, the operating handle 3 forms an angle with the convex structure 4. Specifically, the first position is where the lid 2 is locked to the pot body 1, and the second position is where the lid 2 is unlocked from the pot body 1. Of course, the first position can also be the unlocked position and the second position the locked position, which is not limited here.

[0086] Preferably, a cooling fan is provided within the convex hull structure 4, and the airflow blown by the cooling fan is blown toward the inner cover 22 to cool the inner cover 22, accelerate pressure relief, and shorten the time it takes to open the cover. Specifically, as shown in the figure, the cooling fan is located on one side of the center of the pot lid 2, blowing airflow toward the center of the pot lid 2, while the pressure relief valve 6, the grip portion 31 and other structures are all located on one side of the cooling fan, thereby allowing the airflow to cool the inner cover 22, the pressure relief valve 6 and the grip portion 31 simultaneously, thereby improving the cooling efficiency. Preferably, the convex hull structure 4 is also provided with an air inlet for external airflow to reach the cooling fan from the air inlet.

[0087] Preferably, the pot body 1 is also provided with a cooling fan for blowing cold air toward the outer wall of the inner pot to accelerate the cooling speed in the cooking cavity and improve the pressure reduction efficiency.

[0088] In a preferred embodiment, Figure 2 、 Figure 3 As shown, the top surface of the cover body 21 is further provided with an upwardly protruding support boss, which is used to support the rotating ring 32 , and a gripping gap 312 is defined between the gripping portion 31 and the top surface of the cover body 21 .

[0089] The support boss provides upward support for the rotating ring 32, making the operating handle 3 more stable and preventing it from shaking. A gripping gap 312 is provided between the grip portion 31 and the cover 21, facilitating the user's grip. The user can insert their fingers into the gripping gap and grasp the grip portion 31, allowing for more comfortable operation of the operating handle 3 and enhancing grip comfort and user experience. Furthermore, the presence of the gripping gap 312 allows heat from the cover 21 to dissipate through the gap, preventing excessive heat from being transferred to the grip portion 31. This keeps the grip portion 31 cool, making it easier for the user to grasp.

[0090] like Figure 1 As shown, the grip portion 31 is provided with a grip opening 311 , and the user can insert his fingers into the grip opening 311 and the grip gap 312 below to grasp the edge of the grip portion 31 .

[0091] Of course, the gripping portion 31 may also be of other structures, for example, the gripping portion 31 may be provided with an upwardly protruding handle for the user to grasp.

[0092] In another preferred embodiment, Figure 10 As shown, the gripping portion 31 extends upwardly at an angle relative to the rotating ring 32 , so that a gripping gap 312 is formed between the gripping portion 31 and the top surface of the cover body 21 .

[0093] The grip portion 31 extends upwardly at an angle compared to the rotating ring 32, so that the grip gap 312 between the grip portion 31 and the upper surface of the cover body 21 is increased, thereby leaving enough space between the two to accommodate the user's fingers, allowing the user to grasp the grip portion 31 more completely and improve the gripping feel.

[0094] Preferably, the operating handle 3 gradually rises from the rotating ring 32 to the gripping portion 31 , and the angle between the gripping portion 31 and the horizontal plane is 5°-45° to facilitate the user's grip.

[0095] Preferably, if Figure 7 As shown, the inner cover 22 is provided with a cover tooth 25, and the pot body 1 is provided with a pot tooth 11. When the pot cover 2 is locked with the pot body 1, the cover tooth 25 and the pot tooth 11 are aligned and engaged. When the pot cover 2 and the pot body 1 are unlocked, the cover tooth 25 and the pot tooth 11 are misaligned. The pot cover 2 also includes a pressure-bearing cover 23 located below the inner cover 22, and the pressure-bearing cover 23 is detachably fixed to the inner cover 22.

[0096] The pressure-bearing cover 23 forms the top wall of the cooking space and is in direct contact with the cooking environment within the pot, making it easily contaminated. The pressure-bearing cover 23 is designed to be removable, allowing the user to remove it separately for cleaning. The inner cover 22, on the other hand, houses the pressure relief valve 6 and is designed to be non-removable to ensure a tight seal.

[0097] Specifically, such as Figure 3 、 Figure 11 As shown, a through hole is provided in the center of the pressure cover 23, through which the lower end of the exhaust pipe 61 of the pressure relief valve 6 passes, and a second sealing ring 72 is provided between the two. Since the pressure relief valve 6 is provided in the center of the pot cover 2, the positioning of the pressure cover 23 during installation is also simpler and more convenient, improving the user's installation efficiency.

[0098] In a preferred embodiment, Figure 8 As shown, the operating handle 3 includes a handle base 33 and a handle cover 34 . A avoidance opening 211 is provided at the center of the cover body 21 , and a fixing portion 222 is provided at the center of the inner cover 22 . The fixing portion 222 is fixedly connected to the handle base 33 , and the handle cover 34 covers the handle base 33 .

[0099] The handle seat 33 is fixedly connected to the fixing portion 222 of the inner cover 22 through the avoidance opening 211 in the center of the cover body 21, thereby fixing the operating handle 3 and linking it with the inner cover 22. After installation, the handle cover 34 is placed over the handle seat 33 to complete the assembly of the operating handle 3. Preferably, the handle cover 34 and the handle seat 33 are fixed by snapping together. For example, the handle seat 33 is provided with a plurality of snaps along the circumference, and the handle cover 34 is provided with corresponding snaps that cooperate therewith, thereby firmly fixing the handle cover 34 and the handle seat 33 around the circumference. In one embodiment, the fixing portion 222 is a screw column, which is used to fasten the handle seat 33 and the inner cover 22 together by screw connection. Of course, the two can also be connected by other means, such as snap connection, etc., which are not limited here.

[0100] Preferably, the operating handle 3 extends in the radial direction of the pot cover 2 , there are two fixing portions 222 , and the line connecting the two fixing portions 222 is perpendicular to the extending direction of the operating handle 3 , or the two are coincident.

[0101] The operating handle 3 is designed as a split structure, and the step-by-step installation can reduce the installation difficulty and improve the assembly efficiency. Of course, the operating handle 3 can also be designed as an integrated structure, which is fixedly connected to the inner cover 22 as a whole, which is not limited here.
