Description

Technical Field

[0001] The utility model relates to the technical field of kitchenware, in particular to a pressure cooker cover and a pressure cooker. Background Art

[0002] A pressure cooker is a kitchen appliance that uses high-pressure steam in a sealed pot to accelerate cooking. It uses the heated liquid in the pot to generate steam and form a high-pressure environment in the pot, so that food can be cooked faster. The pressure cooker lid is the main component used to lock and seal the pressure cooker. The quality of the pressure cooker lid will directly affect the cooking effect and cooking safety during use.

[0003] Most of the existing pressure cookers on the market adopt a side buckle or twist buckle locking method. The side buckle pressure cooker lid is usually provided with multiple buckles for fastening the pressure cooker near the side of the pressure cooker lid. The user needs to use both hands to unlock the buckles or one hand to unlock the buckles one by one to loosen the buckles of the pressure cooker lid, which is inconvenient to open.

[0004] The screw-on pressure cooker lid is usually only equipped with bidirectional symmetrical retractable claws, which drive the claws on both sides to retract and retract by rotating the knob in the center to fasten the pressure cooker. However, the symmetrical arrangement of the claws in the pressure cooker still has the risk of side leakage during cooking. Because the intervals between the claws are large, the high-pressure gas in the pot will rush toward the position where the locking force between the claws is relatively weak, resulting in uneven force on the edge of the lid between the claws on both sides and pressure leakage. In addition, the edge of the lid between the claws on both sides will shake slightly and make noise due to the uneven force on both sides due to the high-pressure gas rushing to the top, affecting the cooking environment.

[0031] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, a pressure cooker cover comprises a cover body 100 for locking and sealing the pressure cooker, and a locking mechanism and a pressure regulating mechanism 500 installed on the cover body 100, wherein the locking mechanism comprises at least three locking members 200 for locking and buckling, and a screwing assembly 300 for driving the locking members 200, and a locking groove 11 for sliding the locking member 200 is provided on one side of the cover body 100 close to the locking mechanism, and the locking members 200 and the locking groove 11 are provided in the same number and are both arranged at intervals around the central circumference of the cover body 100;

[0033] The screwing assembly 300 is used to limit the connection between the locking member 200 and the pot cover body 100. When the screwing assembly 300 is rotated, the screwing assembly 300 can drive the locking member 200 to slide along the locking groove 11 in a direction away from the center of the pot cover body 100, or slide in a direction close to the center of the pot cover body 100.

[0034] Specifically, in some embodiments, the pot cover body 100 is a pot cover for installing a locking component and for covering the pressure cooker. The pot cover body 100 adopts a thin-wall design. The side of the pot cover body 100 for installing the locking mechanism and the pressure regulating mechanism 500 is the upper side, and the side of the pot cover body 100 for covering the pressure cooker is the lower side. A plurality of island structures 15 are protruded from the upper surface of the pot cover body 100, and locking grooves 11 that are recessed toward the lower side of the pot cover body 100 are formed between adjacent island structures 15. The length direction of the locking groove 11 extends from the center of the screwing assembly 300 toward the radial outer side of the pot cover body 100. The middle part of the locking member 200 is placed in the locking groove 11. When sliding, the groove wall of the locking groove 11 can limit the locking member 200 from sliding in the length direction of the locking groove 11. The locking member 200 and the screwing assembly 300 are installed on the pot cover body 100. The user drives the locking member 200 to slide along the length direction of the locking groove 11 by rotating the screwing assembly 300, thereby achieving the telescopic locking effect of the locking member 200.

[0035] The locking member 200 is a key component of the locking mechanism for locking the pressure cooker. The locking member 200 can adopt a claw structure to lock the side of the pressure cooker under the drive of the screw assembly 300. The pressure cooker cover can be provided with three or more locking members 200 to meet the mechanical properties required for locking the pressure cooker cover. Multiple locking members 200 lock the pressure cooker at the same time, which can improve the overall locking force and balance the locking force of the pressure cooker cover, avoid uneven force on the side caused by high-pressure gas rushing to the top, and improve the locking stability;

[0036] The screwing assembly 300 is a driving assembly of the pressure cooker lid for driving the locking member 200 to move and retract on the lid body 100. The screwing assembly 300 can be arranged at the middle part of the upper side of the lid body 100, so that the length of each locking member 200 can be as consistent as possible, which is convenient for manufacturing and production installation. When in use, the user can drive the locking member 200 to extend and loosen or retract and lock along the length direction of the locking groove 11 by rotating the screwing assembly 300, so that the user can loosen or tighten the pressure cooker lid with one hand, which is convenient for the user to use;

[0037] The pressure regulating mechanism 500 is a regulating valve for timely adjusting the pressure of the pressure cooker. The pressure regulating mechanism 500 is installed on the island structure 15. When the pressure of the pressure cooker exceeds the set value during cooking, the pressure regulating mechanism 500 will automatically release the pressure to prevent the pressure from continuing to rise and ensure that the pressure in the pot works within a safe pressure range. When the pressure of the pressure cooker exceeds the limit value during cooking, the pressure regulating mechanism 500 will open and release the pressure to prevent the pressure cooker from exploding or causing other serious safety problems due to excessive pressure.

[0038] Specifically, in some embodiments, a sealing shock-absorbing rubber ring 700 is provided on one side of the pot cover body 100 for covering the pressure cooker. The sealing shock-absorbing rubber ring 700 adopts a ring-shaped rubber ring structure connected end to end. A groove structure for shock absorption is provided on the side of the sealing shock-absorbing rubber ring 700 facing the center of the pot cover body 100. The groove structure opens toward the center of the pot cover body 100. When in use, the sealing shock-absorbing rubber ring 700 contacts the edge of the pot mouth of the pressure cooker and is pressed against the pot mouth by the locking force of the pressure cooker cover, thereby achieving an air pressure sealing effect. During the cooking process, the impact of the pressurized gas on the pressure cooker cover can also be eliminated by the characteristics of the flexible material of the sealing shock-absorbing rubber ring 700 to eliminate shaking and vibration, thereby achieving the effect of reducing vibration and noise.

[0039] like Figure 2 and Figure 3 As shown, the locking member 200 includes a locking connector 21 for limiting the sliding direction and a locking fastener 22 for buckling. The locking fastener 22 is fixedly connected to one end of the locking connector 21 away from the screw assembly 300, and the buckling height of the locking fastener 22 is greater than the side height of the pot cover body 100.

[0040] Specifically, in some embodiments, the locking fastener 22 is a claw component of the locking component 200 for locking the pressure cooker. The locking fastener 22 adopts an arc-shaped semi-wrapped structure to facilitate the buckling effect. The locking connector 21 is a connecting component used to connect the locking fastener 22 and the screw assembly 300. One end of the locking connector 21 is movably hinged to the screw assembly 300, and the other end of the locking connector 21 is fixedly connected to the locking fastener 22. The width of the locking fastener 22 is smaller than the slot width of the locking groove 11, so that the locking fastener 22 can be easily placed in the locking groove 11 and It can slide back and forth easily. The locking fastener 22 adopts a thin-walled bending structure. The inner wall height of the locking fastener 22 is greater than the side edge height of the pot cover body 100. When in use, the pot cover body 100 is covered on the pressure cooker. The user can push the locking connector 21 to slide along the length direction of the locking groove 11 by rotating the screw assembly 300. The locking connector 21 slides together with the locking fastener 22 in a direction away from the center of the pot cover body 100, or slides in a direction close to the center of the pot cover body 100, to achieve a locking effect of extending to loosen or closing to lock.

[0041] like Figure 2 and Figure 3 As shown, the locking fastener 22 adopts an arc-shaped curved structure, and the locking fastener 22 is respectively provided with an upper locking portion 221 and a lower locking portion 222 extending toward the center of the pot cover body 100, the upper locking portion 221 is located on the upper side of the locking fastener 22, and the lower locking portion 222 is located on the lower side of the locking fastener 22, and the distance between the upper locking portion 221 and the lower locking portion 222 is greater than the side height of the pot cover body 100.

[0042] Specifically, in some embodiments, the locking fastener 22 adopts a curved structure that is curved in an arc shape around the center of the screw assembly 300, and the upper and lower sides of the curved structure are respectively provided with an upper locking portion 221 and a lower locking portion 222 extending toward the center of the pot cover body 100. When locked, the upper locking portion 221 and the lower locking portion 222 respectively extend from the upper and lower sides of the side position of the pot cover body 100 and tightly fasten the pressure cooker and the pot cover body 100 to form a cooking space in the pot. The distance between the upper locking portion 221 and the lower locking portion 222 is greater than the side height of the pot cover body 100, which facilitates the extension of the locking fastener 22 to implement locking.

[0043] like Figure 2 As shown, the locking mechanism includes a locking cover 23 for covering the locking member 200 . The locking cover 23 is installed between the locking member 200 and the screw assembly 300 . The locking cover 23 is provided with covering portions 231 corresponding in number to the locking member 200 .

[0044] Specifically, in some embodiments, in order to further improve the appearance of the pressure cooker cover, the pressure cooker cover uses a locking cover 23 to cover the middle part of the locking mechanism. The user does not need to see the complex transmission structure between the locking member 200 and the screw assembly 300, and can directly rotate the screw assembly 300 to loosen or lock the pressure cooker cover. Each position of the locking member 200 is covered by a corresponding cover portion 231. More specifically, three or more locking members 200 are arranged around the central circumference of the screw assembly 300 at intervals on the cooker cover body 10. 0, correspondingly, the covering portion 231 is arranged on the locking cover 23 at intervals around the central circumference of the screwing component 300, and the locking cover 23 is located between the locking member 200 and the screwing component 300. The screwing component 300 passes through the locking cover 23 to drive the locking member 200 to slide and retract along the locking groove 11. When in use, the locking cover 23 can block external sauces and materials to avoid falling into the screwing component 300, prevent the screwing component 300 from being eroded by the sauce, and prevent the material from getting stuck at the joint position of the screwing component 300, thereby protecting the operation of the locking mechanism.

[0045] like Figure 2 and Figure 4 As shown, the screwing assembly 300 includes a screwing head 31 for easy screwing and a connecting rod assembly 32 for driving the locking member 200, the locking cover 23 is located between the screwing head 31 and the connecting rod assembly 32, the screwing head 31 is installed on the locking mechanism through the connecting rod assembly 32, and the screwing head 31 is rotated to drive the connecting rod assembly 32, thereby driving the locking member 200 to move.

[0046] Specifically, in some embodiments, the screwing head 31 is a screwing component of the screwing assembly 300 for the user to hold, and an anti-slip structure is provided on the outer side of the screwing head 31 to enhance the friction of the user's hand when using the screwing head 31 to avoid rotation and slipping due to water stains and oil stains. The connecting rod assembly 32 is a transmission component of the screwing assembly 300 for the screwing head 31 to cooperate with the connecting rod assembly 32 to connect the locking component 200. The screwing head 31 uses the connecting rod assembly 32 to pass through the locking cover 23 to hinge the locking component 200. When in use, the screwing head 31 is rotated to drive the connecting rod assembly 32 to drive the locking component 200 to move along the length direction of the locking groove 11 to realize the loosening and locking functions of the pressure cooker cover, so that the user can loosen and tighten the pressure cooker cover with one hand, which is convenient for the user to use.

[0047] like Figure 2 and Figure 4 As shown, the connecting rod assembly 32 includes a transmission member 321 and a connecting rod 322, the transmission member 321 is provided with a transmission rod 323 for installing the connecting rod 322, the end of the connecting rod 322 away from the transmission rod 323 is hinged on the locking member 200, the transmission rod 323 extends into the locking cover 23 and is connected with the screwing head 31, the locking cover 23 is provided with a movable groove 232 for the transmission rod 323 to pass through, and a plurality of the movable grooves 232 are distributed around the central circumference of the locking cover 23 at intervals.

[0048] Specifically, in some embodiments, the connecting rod 322 is a transmission connecting member of the connecting rod assembly 32 for articulating the locking member 200. The transmission member 321 is articulated to one end of the connecting rod 322 through the transmission rod 323, and the locking member 200 is articulated to the other end of the connecting rod 322. The connecting rod 322 adopts an arc-shaped crank structure. Compared with a straight handle structure, when the crank structure rotates, the recessed part of the crank structure can provide a certain space for another adjacent connecting rod 322 to extend into, further increasing the tightness and the rotatable angle of the connecting rod assembly 32. When in use, the user rotates the screwing head 31 to drive the transmission member 321 to rotate, and the transmission rod 323 on the transmission member 321 pushes the locking member 200 to slide along the length direction of the locking groove 11 through the connecting rod 322.

[0049] The movable groove 232 is an arc-shaped groove structure provided on the locking cover 23 for limiting the rotation angle of the screwing assembly 300. A plurality of movable grooves 232 are spaced apart around the central circumference of the locking cover 23. The number of movable grooves 232 is set according to the actual number of transmission rods 323. The groove width of the movable groove 232 is greater than the outer diameter of the transmission rod 323. When the screwing head 31 rotates, the transmission rod 323 is driven to move in the movable groove 232. The two ends of the movable groove 232 respectively limit the upper limit of the clockwise rotation angle and the upper limit of the counterclockwise rotation angle of the screwing head 31. The groove length of the movable groove 232 can be determined according to the sliding distance of the locking component 200, so as to ensure the maximum travel limit of the locking component 200 when locking and releasing.

[0050] like Figure 2 and Figure 7 As shown, the locking groove 11 is provided with a limiting column 12 for limiting the sliding direction of the locking member 200, and the locking member 200 is provided with a limiting groove 24 for the limiting column 12 to extend into, and the locking mechanism includes a limiting fastener 400 for reinforcement, and the limiting fastener 400 passes through the covering portion 231 and is cooperatively connected with the limiting column 12.

[0051] Specifically, in some embodiments, the limiting column 12 is a hollow column structure integrally formed on the locking groove 11 for limiting the sliding direction of the locking member 200. The limiting column 12 extends and stands upright from the locking groove 11 toward the upper side of the pot cover body 100. The limiting groove 24 is a straight groove structure provided in the middle of the locking member 200 for the limiting column 12 to extend into. The groove width of the limiting groove 24 is greater than the outer diameter of the limiting column 12 so that the limiting column 12 can easily extend into the limiting groove 24. The length direction of the limiting groove 24 is in the same direction as the sliding direction of the locking member 200. When in use, the user rotates the screwing assembly 300 to drive the locking member 200 to slide along the length direction of the locking groove 11. The sliding of the locking member 200 is controlled by the gap of the limiting column 12 in the limiting groove 24 to prevent the deviation of the sliding member 200 from deviating to both sides, thereby further controlling the locking force distribution balance of the locking member 200 on the pressure cooker.

[0052] The limiting fastener 400 is a fastening accessory used to lock the covering part 231 on the pot cover body 100. The limiting fastener 400 passes through the covering part 231 and is connected with the limiting column 12, so that when the locking part 200 slides, the locking cover 23 will not move with the sliding of the locking part 200, avoiding shaking and noise, and also playing a certain aesthetic role.

[0053] like Figure 2 and Figure 4 As shown, the screwing head 31 includes an anti-slip shell 311, a screwing limiter 312 and a screwing cover 313. The anti-slip shell 311 is installed between the screwing limiter 312 and the locking cover 23. The screwing cover 313 is buckled on the side of the screwing limiter 312 away from the locking cover 23. The anti-slip shell 311 and the screwing cover 313 enclose an installation space 314 for installing the screwing limiter 312.

[0054] Specifically, in some embodiments, the anti-skid shell 311 is a shell component installed on the outside of the screwing head 31 for the user's hand to directly contact and screw. The outside of the anti-skid shell 311 is provided with convex and concave anti-skid patterns. The anti-skid patterns are circumferentially arranged on the anti-skid shell 311 around the central axis of the screwing head 31. The anti-skid patterns are convex and concave toward the upper side or the lower side of the pot cover body 100. When the user rotates the screwing head 31, the anti-skid patterns can avoid slipping due to water stains or oil stains. The screwing limiter 312 is installed The interior of the anti-slip housing 311 is used for connecting the connection parts of the pot cover body 100. A central column structure for connecting the screw limiter 312 is extended from the middle of the pot cover body 100. The height of the central column structure can be set according to the actual thickness of the locking cover 23 and the locking member 200 installed on the pot cover body 100. If the height of the central column structure is too small, the resistance of the user to turning the screw head 31 will increase. If the height of the central column structure is too large, the locking cover 23 and the locking member 200 will shake. When the central column structure extends from the bottom of the anti-slip shell 311, the user uses screws or bolts to pass through the screw limiter 312 to connect to the central column structure. The screw cover 313 is a covering component installed on the side of the anti-slip shell 311 away from the pot cover body 100. The screw cover 313 can play a role in covering the internal structure of the screw head 31 for beauty. The outer shape of the screw cover 313 matches the opening shape on the upper side of the anti-slip shell 311. The screw cover 313 is provided with a screw limiter for easy connection. The screw limiter 312 is provided with a clamping portion for the clamping portion to extend into, and the clamping portion and the clamping portion are matched and connected so that the screw cover 313 is stably installed on the screw limiter 312. The screw head 31 adopts a split structure design consisting of an anti-slip shell 311, a screw limiter 312 and a screw cover 313, which helps to avoid the heat transfer of the pressure cooker during cooking causing the surface temperature of the screw head 31 to be too high to affect the user's hand screwing, reduce heat burns to the user's hand, and facilitate user use.

[0055] like Figure 2 , Figure 5 and Figure 6 As shown, the pressure regulating mechanism 500 includes a pressure limiting valve 51 and a safety valve 52 installed on the pot cover body 100. The pot cover body 100 is provided with a first valve port 13 for installing the pressure limiting valve 51 and a second valve port 14 for installing the safety valve 52. The aperture of the first valve port 13 is larger than the aperture of the second valve port 14.

[0056] Specifically, in some embodiments, the pressure limiting valve 51 is a pressure relief valve used by the pressure regulating mechanism 500 to control the internal pressure of the pressure cooker within a safe range. When the pressure of the pressure cooker exceeds the set value during cooking, the pressure cooker cover can automatically release the pressure through the pressure limiting valve 51, thereby preventing the pressure from continuing to rise, ensuring that the pressure cooker continues to cook within a safe pressure range; the safety valve 52 is a pressure relief valve used by the pressure regulating mechanism 500 to serve as a safety guarantee in extreme cases (such as failure of the pressure limiting valve 51). When the pressure of the pressure cooker exceeds the limit value during cooking or the pressure limiting valve 51 fails, the pressure cooker cover can open the safety valve 52 and release the pressure in the pot to prevent explosion or other serious safety problems caused by excessive pressure, thereby further improving the stability and safety of the pressure cooker cover. The aperture of the first valve port 13 is larger than the aperture of the second valve port 14, which can further increase the pressure flow rate in an emergency, so that the safety valve 52 can handle excessive pressure at a faster speed, ensuring the safety of the pressure cooker.

[0057] like Figures 5 to 8 As shown, the pressure cooker comprises a pressure cooker body 600 and a pressure cooker cover for covering the cooker body. The pressure cooker body 600 is provided with a cooker body opening 61 for the pressure cooker cover to buckle. The cooker body opening 61 is provided with a cooker body buckling portion 62 extending outward and bending downward. The screwing assembly 300 can drive the locking member 200 to buckle on the cooker body buckling portion 62 to form a closed space 63.

[0058] Specifically, in some embodiments, the pressure cooker body 600 is a container body for holding and cooking food. The pressure cooker body 600 is provided with a pressure cooker cavity for placing food. The upper side of the pressure cooker cavity is provided with a pot body opening 61 connected to the outside. The pot body buckle part 62 is located at the edge of the pot body opening 61, extends outward and bends downward. The pot body buckle part 62 is arranged around the central circumference of the pressure cooker body 600 along the edge of the pot body opening 61. When in use, the pressure cooker lid is buckled in the pot body opening 61. The user drives the locking member 200 to tighten and lock in the pot body buckle part 62 by rotating the screw assembly 300, so that the pressure cooker lid is buckled in the pot body opening 61. The pot lid and the pressure cooker body 600 are covered to form a closed space 63 for high-pressure cooking. More specifically, when the pressure cooker lid is buckled on the pot body opening 61, the sealing shock-absorbing rubber ring 700 contacts the edge of the pot body opening 61. When the locking member 200 is tightened and locked on the pot body buckling portion 62, the sealing shock-absorbing rubber ring 700 is pressed and contacts the edge of the pot body opening 61 more closely, further ensuring the airtightness of the pressure cooker. During the cooking process, the impact of pressurized gas on the pressure cooker lid can also be eliminated by the characteristics of the flexible material of the sealing shock-absorbing rubber ring 700 to eliminate shaking and vibration, thereby achieving the effect of reducing vibration and noise.

[0059] Specifically, in some embodiments, the outer side of the pressure cooker body 600 is provided with a pot grip 64 for the user to hold and lift the pressure cooker. The pot grip 64 is respectively provided on both sides of the outer side of the pressure cooker body 600 near the pot opening 61. The pot grip 64 can be made of one or a combination of materials such as metal, plastic, wood or stone with poor thermal conductivity, so as to reduce the influence of high temperature after cooking on the user to move the pressure cooker body 100.

[0060] like Figures 1 to 9 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0061] When the user needs to lock the pressure cooker lid, the lid body 100 is closed on the pot body opening 61. The user can drive the transmission member 321 to rotate by rotating the screw head 31. The multiple transmission rods 323 on the transmission member 321 respectively pull the multiple locking members 200 to slide along the length direction of the locking groove 11 through the connecting rod 322. During sliding, the limiting column 12 limits the movable gap of the limiting groove 24 to further control the moving direction during sliding. The locking connector 21 slides together with the locking fastener 22 toward the center of the lid body 100, so that the locking member 200 is tightened and locked on the pot body fastening portion 62, and the pressure cooker lid is locked on the pressure cooker body 600.

[0062] When the user needs to open the pressure cooker lid, the user can drive the transmission member 321 to rotate by rotating the screwing head 31. The multiple transmission rods 323 on the transmission member 321 push the multiple locking members 200 to slide along the length direction of the locking groove 11 through the connecting rod 322. During sliding, the limiting column 12 limits the movable gap of the limiting groove 24 to further control the moving direction during sliding. The locking connector 21 slides together with the locking fastener 22 in a direction away from the center of the pot cover body 100, so that the locking member 200 is loosened and disengaged from the pot body fastening portion 62. The user holds the screwing head 31 with his hand to lift the pressure cooker lid in a direction away from the center of the pressure cooker body 600 to complete the opening of the pressure cooker lid.

[0063] like Figures 1 to 9 As shown, the specific implementation of Example 2 of the utility model is as follows:

[0064] Different from the first embodiment, a pressure limiting valve 51 and a safety valve 52 are installed on the pot cover body 100 of the present embodiment.

[0065] When the pressure in the pressure cooker exceeds the set value during cooking, the pressure cooker cover can automatically release the pressure through the pressure limiting valve 51, thereby preventing the pressure from continuing to rise, ensuring that the pressure cooker continues to cook within a safe pressure range. When the pressure in the pressure cooker exceeds the limit value during cooking or the pressure limiting valve 51 fails, the pressure cooker cover can open the safety valve 52 and release the pressure in the cooker to prevent explosion or other serious safety problems caused by excessive pressure, thereby further improving the stability and safety of the pressure cooker cover.

[0066] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
