[0003] In view of this, the present application provides a pressure cooker lid and a pressure cooker, so as to solve the problem that the pressure cooker in the prior art cannot be opened immediately due to the pressure inside the pot.

[0004] In a first aspect, an embodiment of the present application provides a pressure cooker lid, comprising a lid body and a pressure limiting assembly, wherein the pressure limiting assembly is mounted on the lid body, and the pressure limiting assembly comprises a valve assembly and a control member. The valve assembly comprises a pressure relief channel and a valve core for blocking or opening the pressure relief channel, the control member is located on the outer side of the lid body and connected to the valve core, and the control member is used to drive the valve core to move along its own axial direction, so that the pressure relief channel is blocked when the valve core moves to a first position, and the pressure relief channel is opened when the valve core moves to a second position.

[0005] In the embodiment of the present application, a control member connected to the valve core is provided on the outer side of the cover body, and the user directly changes the position of the valve core by operating the control member, thereby controlling the valve core to open or block the pressure relief channel. For example, after the pressure cooker finishes cooking, the user can operate the control member to move the valve core to the second position to open the pressure relief channel, so that the steam retained in the pressure cooker is quickly discharged, that is, the manual steam exhaust function of the pressure cooker is realized, thereby reducing the pressure in the pot, making it convenient to remove the pressure cooker lid and take out the food in the pot. When the pressure cooker lid is closed on the pot body again, the user can operate the control member to move the valve core from the second position to the first position to block the pressure relief channel, so that the pressure cooker can achieve normal pressure, so as to facilitate the next cooking work. Such a design is conducive to improving the convenience of using the pressure cooker, reducing the time required for the user to wait for the lid to be opened, and facilitating the user to quickly take out the food in the pot, thereby helping to improve the user's experience. Among them, arranging the control member on the outer side of the cover body is conducive to saving space inside the pressure cooker lid, thereby helping to reduce the thickness of the pressure cooker lid, and at the same time, it is convenient for the user to operate the control member, which is conducive to further improving the user's experience.

[0006] In a possible embodiment, the cover body includes an outer cover and an inner cover connected to the outer cover, the control member is located on a side of the outer cover away from the inner cover, the pressure relief channel is located on a side of the outer cover close to the inner cover, the valve core penetrates the outer cover along the axial direction of the outer cover, one end of the valve core is connected to the control member, and the other end of the valve core is used to block or open the pressure relief channel.

[0007] This design allows the control element to be directly connected to the valve core, reducing the possibility of setting other linkage components between the control element and the valve core, thereby helping to simplify the structure of the pressure limiting assembly, facilitating the assembly of the pressure limiting assembly, and also helping to improve the reliability of the pressure limiting assembly.

[0008] In a possible implementation, the control member includes a toggle portion and a connecting portion, wherein the connecting portion is connected to the valve core, and the toggle portion is connected to the connecting portion and extends along the axial direction of the cover body in a direction away from the outer cover.

[0009] The connection part is provided to improve the stability and reliability of the connection between the control member and the valve core, so that the control member can drive the valve core to move. The toggle part is provided to increase the contact area between the user's hand and the control member, so that the user can grasp the control member to operate the control member accordingly, thereby improving the user experience.

[0010] In a possible embodiment, the connecting portion includes a slide groove extending radially along the valve core, the slide groove has a first end face, and the valve core includes a matching portion, the matching portion is located in the slide groove and abuts against the first end face; the valve core can move along the first end face relative to the control member to switch between the first position and the second position.

[0011] By moving the control member left and right along the radial direction of the valve core to control the up and down movement of the valve core, that is, controlling the valve core to open or block the pressure relief channel, it is helpful to simplify the operation steps. At the same time, this embodiment does not need to pull up or press down the control member, which is easier for users to operate, thereby helping to improve the user experience.

[0012] In a possible embodiment, the first end surface includes a first platform segment and a second platform segment; the first platform segment is connected to the second platform segment along the radial side of the valve core; along the axial direction of the valve core, the second platform segment is located on the side of the first platform segment away from the outer cover; when the mating portion abuts against the first platform segment, the valve core is in the first position; when the mating portion abuts against the second platform segment, the valve core is in the second position.

[0013] The first platform section and the second platform section guide the movement of the valve core, so that the valve core can open or block the pressure relief channel as the control member moves left and right, thereby facilitating user operation.

[0014] In a possible implementation manner, a handle is installed on the outer side of the outer cover; the control component is accommodated in the handle and is movably connected to the handle.

[0015] The handle provides installation space for the control part, thereby improving the stability of the control part installation and reducing the possibility of the control part falling off the outer cover. At the same time, the handle also protects the connection between the control part and the valve core, thereby improving the stability and reliability of the connection between the control part and the valve core. In addition, accommodating the control part in the handle is conducive to saving the volume of the entire pressure cooker lid, which is convenient for packaging and storing the pressure cooker lid.

[0016] In a possible implementation manner, the handle is provided with a handle cover; the handle cover is provided with a lever slidable relative to the handle cover; and the toggling portion is connected to the lever.

[0017] The user operates the control element by toggling the lever, which is convenient for the user to operate and helps to improve the user experience.

[0018] In a possible implementation, the outer cover includes a first outer cover and a second outer cover, the first outer cover is connected to the inner side of the second outer cover through a fixed bracket; the first outer cover is provided with a pressure relief hole connected to the pressure relief channel; the second outer cover includes a supporting portion and a hollow portion, the valve core is located in the supporting portion, and the pressure relief hole is connected to the outside through the hollow portion.

[0019] The pressure relief hole is provided on the first outer cover, so as to facilitate the pressure relief of the pressure cooker and improve the safety of the pressure cooker. The support portion of the second outer cover provides an installation space for the valve core. The hollow portion of the second outer cover is conducive to the connection between the pressure relief hole and the outside world, thereby facilitating the safety of the pressure cooker. At the same time, the hollow portion is also conducive to reducing the dead weight of the outer cover, making it easier for users to take the pressure cooker cover.

[0020] In a possible embodiment, a valve sleeve is provided on the outer side of the valve core; an elastic member is provided between the valve sleeve and the valve core, and two ends of the elastic member are respectively abutted against the valve sleeve and the valve core; the pressure limiting assembly also includes an adjusting member, which is cooperatively connected with the valve sleeve, and the adjusting member can drive the valve sleeve to move relative to the valve core along the axial direction of the valve core to cause the elastic member to deform.

[0021] The pressure limiting assembly of the embodiment of the present application has a pressure regulating function. By operating the adjusting member, the valve sleeve is driven to move, thereby changing the force of the elastic member acting on the valve core, and then changing the normal working pressure value in the pressure cooker to play a pressure regulating role. Specifically, the adjusting member can be preset with gears, gears and gears. Gear can be understood as neutral gear. When the adjusting member is in gear, the valve core blocks the pressure relief channel, and the pressure in the pressure cooker can be normally pressurized. When the pressure value in the pressure cooker reaches A under the gear, the valve core is pushed up under the pressure to open the pressure relief channel, so that the pressure cooker is relieved. By rotating the adjusting member to put it in gear, the adjusting member drives the valve sleeve to move along the axial direction of the valve core toward the side close to the pressure relief channel to increase the compression of the elastic member. At this time, the force of the elastic member acting on the valve core becomes larger, resulting in the pressure value in the pressure cooker needing to rise to A (i.e. A>A) before the valve core can be pushed up to relieve pressure. That is, it can be understood that as the force of the elastic member acting on the valve core increases, the pressure value required to open the pressure relief channel increases. Similarly, when the adjusting member rotates from gear to gear, the valve sleeve further compresses the elastic member to increase the force of the elastic member acting on the valve core, and the pressure relief channel can be opened only when the pressure value in the pressure cooker rises to A (i.e., A>A). In the above process, since the force of the elastic member acting on the valve core continues to increase, the pressure value required to open the pressure relief channel also continues to increase, so that the pressure value of the pressure cooker during cooking continues to increase. For example, when the pressure cooker is in gear, the pressure cooker can perform normal pressure cooking at a pressure value of A or A. The adjusting member can adjust the pressure in the pressure cooker to increase. Of course, according to the actual use needs of the pressure cooker, the adjusting member can also adjust the pressure in the pressure cooker to decrease. When the pressure cooker heats the food, the adjusting member can be operated to adjust the pressure value of the pressure cooker according to the type of food to ensure the cooking effect of the pressure cooker, that is, the pressure cooker meets the cooking needs of different foods, which is conducive to meeting the diverse use needs of users and improving the user experience.

[0022] In a possible implementation, the valve sleeve has a first gear portion; the adjusting member has a second gear portion, the second gear portion is meshed with the first gear portion, and when the adjusting member rotates relative to the valve sleeve, the adjusting member is used to drive the valve sleeve to rotate and move along the axial direction of the valve core.

[0023] The adjusting member is connected to the valve sleeve in a gear meshing manner, which is conducive to achieving a stable transmission relationship between the adjusting member and the valve sleeve, and is conducive to the pressure cooker to achieve a reliable pressure regulation function. The user can adjust the pressure value in the pressure cooker by turning the adjusting member, which simplifies the user's operation steps and reduces the difficulty of operation, thereby helping to improve the user's experience.

[0024] In a possible implementation manner, the valve assembly includes a valve bracket fixedly connected to the cover body; the valve core and the valve sleeve are accommodated in the valve bracket, and the valve sleeve is threadedly connected to the valve bracket.

[0025] The above design is conducive to improving the stability of the connection between the elastic member and the valve sleeve and the valve core, so that the elastic member can provide a stable and reliable force for the valve core.

[0026] In a possible implementation, the valve bracket includes a mounting portion and a pressure relief portion connected to the mounting portion along one side of the valve core axial direction; the valve sleeve and the valve core are accommodated in the mounting portion; along the axial direction of the valve core, the valve sleeve and the valve core are used to abut against the bottom wall of the mounting portion; the pressure relief channel is arranged in the pressure relief portion, and the bottom wall of the mounting portion is provided with a valve head through-hole connected to the pressure relief channel, and the valve head of the valve core extends into the pressure relief channel through the valve head through-hole.

[0027] Along the axial direction of the valve core, the valve sleeve and the valve core are used to abut against the bottom wall of the mounting portion to limit the valve sleeve and the valve core. The embodiment of the present application is conducive to improving the stability and reliability of the installation of the valve core and the valve sleeve while achieving pressure increase and pressure relief of the pressure cooker by providing the pressure relief portion and the mounting portion.

[0028] In a possible embodiment, the pressure relief portion includes a main body and a bottom cover installed on the main body; the main body is provided with a steam outlet extending along the radial direction of the valve core; the bottom cover is provided with a steam inlet extending along the axial direction of the valve core; the steam inlet is connected with the steam outlet to form the pressure relief channel, and the valve head is used to block or open the steam inlet.

[0029] The embodiment of the present application sets the steam inlet on the bottom cover, and forms a complete pressure relief channel after the bottom cover and the main body are assembled, thereby reducing the possibility of simultaneously setting the steam inlet and the steam outlet on the main body, which is conducive to reducing the difficulty of processing the main body and improving the structural strength of the main body. At the same time, when food residues accumulate in the steam inlet and cause the pressure relief process to be unsmooth, the bottom cover can be removed to clean the air inlet or directly replaced with a new bottom cover to ensure normal pressure relief of the pressure cooker, thereby improving the safety of the pressure cooker.

[0030] In a possible implementation manner, the pressure relief portion is connected to an anti-blocking cover; the bottom cover is located inside the anti-blocking cover; the anti-blocking cover is provided with a connecting hole, and the connecting hole is connected to the steam inlet.

[0031] By providing an anti-blocking cover, steam can enter the steam inlet through the connecting hole, while food residues are filtered out, thereby reducing the possibility of the pressure relief channel being blocked by food residues, resulting in an unsmooth pressure relief process or even failure of normal pressure relief, which is beneficial to improving the safety of the pressure cooker.

[0032] In a possible embodiment, the cover body includes an outer cover and an inner cover connected to the outer cover; the valve bracket is connected to the outer cover; the anti-blocking cover passes through the inner cover and is connected to the inner cover through a second sealing member; wherein a pressure relief space connected to the pressure relief channel is formed between the outer cover and the inner cover; the inner cover can undergo elastic deformation to generate a pressure relief gap connected to the pressure relief space between the inner cover and the second sealing member under pressure.

[0033] During the process of pressure relief of the pressure cooker, the steam discharged from the pressure relief channel usually flows at a fast speed, and the pressure relief space can buffer the steam, reducing the possibility of strong steam or liquid being discharged to the outside and causing safety hazards to users, thereby helping to improve the safety of the pressure cooker. Under the action of the pressure in the pot, the inner cover can undergo elastic deformation toward the side close to the outer cover. At this time, a pressure relief gap connected to the pressure relief space will be generated between the inner cover and the second sealing member. The steam in the pot can enter the pressure relief space through the pressure relief gap and then be discharged to the outside, thereby playing a role of rapid pressure relief, reducing the possibility of explosion caused by continuous increase in internal pressure of the pressure cooker due to untimely pressure relief, thereby helping to improve the safety and reliability of the pressure cooker. When the pressure value in the pot returns to the normal range, the inner cover can return to its initial shape and connect to the second sealing member to ensure the normal operation of the pressure cooker.

[0034] In a second aspect, an embodiment of the present application provides a pressure cooker, comprising a pot body and a pressure cooker lid, wherein the pressure cooker lid is covered on the pot body, and the pressure cooker lid is any one of the pressure cooker lids described above.

[0035] Since the pressure cooker cover has the above-mentioned technical effects, the pressure cooker having the pressure cooker cover also has the above-mentioned technical effects, which will not be described in detail here.

[0036] In a possible implementation, the pot body includes a pot tooth that is buckled with the pressure cooker lid; the pressure cooker lid includes a stop-opening assembly, and the stop-opening assembly includes a float and a lock; wherein the float has a first state of sinking and a second state of floating; when the float is in the first state, the lock can move radially along the pressure cooker lid under the push of the pot tooth to release the limitation between the pressure cooker lid and the pot body; when the float is in the second state, the lock is limited by the float in the radial direction of the pressure cooker lid to limit the position of the pressure cooker lid on the pot body.

[0037] The pressure cooker is provided with a stop-opening component, which helps to reduce the possibility that the lid of the pressure cooker is opened by mistake during cooking and the user may be scalded by high-temperature steam, thereby helping to improve the safety of the pressure cooker.

[0038] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0065] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0066] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0067] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0068] like Figure 1 As shown, the embodiment of the present application provides a pressure cooker cover 100 and a pressure cooker 1000. The pressure cooker 1000 comprises a pot body 200 and a pressure cooker cover 100, wherein the pressure cooker cover 100 covers the pot body 200.

[0069] The pressure cooker lid 100 can be connected to the pot body 200 through the third sealing member 300, thereby facilitating the improvement of the sealing performance between the pressure cooker lid 100 and the pot body 200. Specifically, the third sealing member 300 can be an annular sealing ring, and its material can also be rubber or silicone.

[0070] Continue to refer Figure 1 The pressure cooker lid 100 includes a cover body 10 and a pressure limiting assembly 20, and the pressure limiting assembly 20 is installed on the cover body 10. The pressure limiting assembly 20 includes a valve assembly 20a and a control member 26, and the control member 26 is located outside the cover body 10. Figure 2 As shown, the valve assembly 20a includes a valve core 21 and a pressure relief passage 272a.

[0071] The pressure relief channel 272a is used to discharge the steam in the pressure cooker 1000 to the outside, so as to keep the pressure value in the pressure cooker 1000 within a normal range, thereby reducing the possibility of explosion of the pressure cooker 1000.

[0072] The valve core 21 is rod-shaped and can move along the axial direction Z of the pressure cooker 1000 to block or open the pressure relief channel 272a of the valve assembly 20a. Specifically, the pressure cooker 1000 has a pressure-up state and a pressure relief state. When the pressure cooker 1000 is in the pressure-up state, the valve core 21 blocks the pressure relief channel 272a, so that the steam generated in the pressure cooker 1000 cannot be discharged to the outside, thereby facilitating the rapid increase of the pressure in the pot to heat the food. When the pressure cooker 1000 is in the pressure relief state, the valve core 21 moves along the axial direction Z of the pressure cooker 1000 in the direction away from the pressure relief channel 272a under the action of the pressure in the pot, and the pressure relief channel 272a is opened, and the steam is discharged to the outside through the pressure relief channel 272a. When the pressure in the pot returns to normal, the valve core 21 can move along the axial direction Z of the pressure cooker 1000 toward the pressure relief channel 272a, that is, the valve core 21 blocks the pressure relief channel 272a again, so that the pressure cooker 1000 can be pressurized.

[0073] The control member 26 is connected to the valve core 21, and is used to drive the valve core 21 to move along its own axial direction. Since the control member 26 is located outside the cover body 10, the user can directly operate the control member 26 to change the position of the valve core 21. When the valve core 21 moves to the first position, the valve core 21 blocks the pressure relief channel 272a; when the valve core 21 moves to the second position, the valve core 21 opens the pressure relief channel 272a.

[0074] In some embodiments, the control member 26 can move up and down along the axial direction Z of the pressure cooker 1000, thereby driving the valve core 21 to move up and down. Specifically, when the control member 26 moves downward, it drives the valve core 21 to move downward to the first position, so that the valve core 21 blocks the pressure relief channel 272a, so that the pressure cooker 1000 can be pressurized. When the control member 26 moves upward, it can drive the valve core 21 to move upward, so that the valve core 21 opens the pressure relief channel 272a, so that the pressure cooker 1000 can be depressurized.

[0075] In other embodiments, the control member 26 can move left and right along the radial direction X of the pressure cooker 1000, thereby driving the valve core 21 to move up and down, so that the valve core 21 switches between the first position and the second position.

[0076] At present, after the pressure cooker 1000 finishes cooking, the lid cannot be opened immediately due to the high pressure inside the pot. The lid can only be opened after the pressure inside the pot drops, which causes the user to wait for a long time before taking out the food from the pressure cooker, affecting the user's experience. In the embodiment of the present application, a control member 26 connected to the valve core 21 is provided on the outer side of the cover body 10. The user directly changes the position of the valve core 21 by operating the control member 26, thereby controlling the valve core 21 to open or block the pressure relief channel 272a. For example, after the pressure cooker 1000 finishes cooking, the user can open the pressure relief channel 272a by operating the control member 26 to move the valve core 21 to the second position, so that the steam retained in the pressure cooker 1000 is quickly discharged, that is, the manual exhaust function of the pressure cooker 1000 is realized, so that the pressure inside the pot drops, which is convenient for removing the pressure cooker lid 100 and taking out the food in the pot. When the pressure cooker lid 100 is closed on the pot body 200 again, the user can operate the control member 26 to move the valve core 21 from the second position to the first position to block the pressure relief channel 272a, so that the pressure cooker 1000 can be normally pressurized to facilitate the next cooking work. Such a design is conducive to improving the convenience of using the pressure cooker 1000, reducing the time required for the user to wait for the lid to be opened, and facilitating the user to quickly take out the food in the pot, thereby helping to improve the user's experience. Among them, arranging the control member 26 on the outside of the lid body 10 is conducive to saving space inside the pressure cooker lid 100, thereby helping to reduce the thickness of the pressure cooker lid 100, and at the same time, it is convenient for the user to operate the control member 26, which is conducive to further improving the user's experience.

[0077] like Figure 3 As shown, in a possible embodiment, the cover body 10 includes an outer cover 11 and an inner cover 12 connected to the outer cover 11. The outer cover 11 is located on the outer side of the inner cover 12. The control member 26 is located on the side of the outer cover 11 away from the inner cover 12, that is, the control member 26 is located on the outer side of the outer cover 11. The pressure relief channel 272a is located on the side of the outer cover 11 close to the inner cover 12, that is, the pressure relief channel 272a is located on the inner side of the outer cover 11. The valve core 21 penetrates the outer cover 11 along the axial direction Z of the outer cover 11, and one end of the valve core 21 located on the outer side of the outer cover 11 is connected to the control member 26, and one end of the valve core 21 located on the inner side of the outer cover 11 is used to block or open the pressure relief channel 272a.

[0078] This design allows the control member 26 to be directly connected to the valve core 21, reducing the possibility of setting other linkage components between the control member 26 and the valve core 21, thereby helping to simplify the structure of the pressure limiting assembly 20, facilitating the assembly of the pressure limiting assembly 20, and also helping to improve the reliability of the pressure limiting assembly 20.

[0079] like Figure 3 and Figure 4As shown, in a possible implementation, the control member 26 includes a toggle portion 263 and a connecting portion 264. The connecting portion 264 is connected to the valve core 21. The toggle portion 263 may be cylindrical and connected to the connecting portion 264. The toggle portion 263 extends in a direction away from the outer cover 11 along the axial direction Z of the cover body 10, and the user can move the control member 26 by grasping the toggle portion 263.

[0080] The connection portion 264 is provided to improve the stability and reliability of the connection between the control member 26 and the valve core 21, so that the control member 26 can drive the valve core 21 to move. The toggle portion 263 is provided to increase the contact area between the user's hand and the control member 26, so that the user can grasp the control member 26 to perform corresponding operations on the control member 26, thereby improving the user's experience.

[0081] Furthermore, the control member 26 can be made of plastic, metal or other materials. The toggle portion 263 and the connecting portion 264 can be integrally formed to improve the stability of the connection between the toggle portion 263 and the connecting portion 264, thereby improving the reliability of the control member 26 and extending the service life of the control member 26.

[0082] like Figure 4 and Figure 5 As shown, in a possible implementation, the connecting portion 264 includes a slide groove 261 extending along the radial direction of the valve core 21. The slide groove 261 has a first end surface 262, and the valve core 21 includes a matching portion 213, which is located in the slide groove 261 and abuts against the first end surface 262; the valve core 21 can move relative to the control member 26 along the first end surface 262 to switch between the first position and the second position.

[0083] The matching portion 213 has a T-shaped structure. The matching portion 213 includes a matching section 213a and a limiting section 213b connected to the matching section 213a. The diameter of the matching section 213a is smaller than the diameter of the limiting section 213b. The matching section 213a extends into the slide groove 261. The limiting section 213b abuts against the first end face 262 along the axial direction Z of the valve core 21 to limit the position of the valve core 21. Since the matching section 213a abuts against the above-mentioned first end face 262, the control member 26 drives the valve core 21 to switch between the first position and the second position by moving along the radial direction X of the valve core 21.

[0084] By moving the control member 26 left and right along the radial direction X of the valve core 21 to control the up and down movement of the valve core 21, that is, controlling the valve core 21 to open or block the pressure relief channel 272a, it is helpful to simplify the operation steps. At the same time, this embodiment does not need to pull up or press down the control member 26, which is easier for users to operate, thereby helping to improve the user experience.

[0085] like Figure 4 As shown, in a possible implementation, the first end surface 262 includes a first platform segment 262a and a second platform segment 262b. Along the axial direction Z of the valve core 21, the first platform segment 262a is located below the second platform segment 262b. The first platform segment 262a is connected to one side of the second platform segment 262b along the radial direction X of the valve core 21. Specifically, the first platform segment 262a can be connected to the second platform segment 262b through an inclined segment 262c.

[0086] Combined with Figure 2 As shown, when the matching portion 213 abuts against the first platform section 262a, the valve core 21 is in the first position and blocks the pressure relief channel 272a. The moving control member 26 moves the valve core 21 from the first platform section 262a to the second platform section 262b via the inclined section 262c, so that the matching portion 213 abuts against the second platform section 262b. At this time, the valve core 21 is in the second position. Since the position of the second platform section 262b is higher than the first platform section 262a, the valve core 21 moves away from the pressure relief channel 272a, thereby opening the pressure relief channel 272a.

[0087] The first platform section 262a and the second platform section 262b guide the movement of the valve core 21, so that the valve core 21 can open or block the pressure relief channel 272a as the control member 26 moves left and right, thereby facilitating user operation.

[0088] like Figure 6 As shown, the pressure cooker lid 100 has an operating assembly 60 for the user to grasp. The operating assembly 60 is connected to the outer cover 11 through a heat insulation pad 80, which is conducive to reducing the possibility of the user being scalded when touching the operating assembly 60, so as to improve the safety of the pressure cooker 1000.

[0089] In a possible implementation, the operating assembly 60 includes a handle 61. The handle 61 is installed on the outside of the outer cover 11. The control member 26 is received in the handle 61 and is movably connected to the handle 61.

[0090] Specifically, the control member 26 has a receiving space, and the connection between the control member 26 and the valve core 21 is located in the receiving space. The handle 61 provides an installation space for the control member 26, which is conducive to improving the stability of the control member 26 and reducing the possibility of the control member 26 falling off the outer cover 11. At the same time, the handle 61 also protects the connection between the control member 26 and the valve core 21, which is conducive to improving the stability and reliability of the connection between the control member 26 and the valve core 21. In addition, accommodating the control member 26 in the handle 61 is conducive to saving the volume of the entire pressure cooker cover 100, and is convenient for packaging and storing the pressure cooker cover 100.

[0091] like Figure 4 and Figure 6 As shown, in a possible implementation, the handle 61 is provided with a handle cover 62, which is buckled on the upper end of the handle 61. The handle cover 62 is provided with a lever 63 that can slide relative to the handle cover, and the toggle portion 263 is connected to the lever 63. The user operates the control member 26 by toggling the lever 63, which is convenient for the user to operate, thereby facilitating the user's experience.

[0092] like Figure 3 , Figure 6 and Figure 7 As shown, in a possible implementation, the outer cover 11 includes a first outer cover 111 and a second outer cover 112, and the first outer cover 111 is connected to the inner side of the second outer cover 112 through a fixing bracket 113. The first outer cover 111 is a circular flat plate, and the first outer cover 111 is provided with a pressure relief hole 111a connected to the pressure relief channel 272a, and the number of the pressure relief holes 111a can be one or more. The second outer cover 112 includes a support portion 112a and a hollow portion 112b, the valve core 21 is located in the support portion 112a, and the pressure relief hole 111a is connected to the outside through the hollow portion 112b.

[0093] Specifically, the material of the first outer cover 111 includes, but is not limited to, glass. In some embodiments, the material of the first outer cover 111 can be transparent glass. A portion of the first outer cover 111 can be exposed from the hollow portion 112b, so that the outside world can observe the internal situation of the pressure cooker 1000 through the first outer cover 111. That is, the first outer cover 111 can serve as a visual window. For example, the situation of the inner cover 12 can be observed through the first cover plate to ensure that it is in a normal use state.

[0094] In other embodiments, the first cover plate may be made of opaque glass, or other materials such as metal.

[0095] The pressure relief hole 111a is provided on the first outer cover 111, so as to facilitate the pressure relief of the pressure cooker 1000, thereby improving the safety of the pressure cooker 1000. The support portion 112a of the second outer cover 112 provides an installation space for the valve core 21. The hollow portion 112b of the second outer cover 112 is conducive to achieving the communication between the pressure relief hole 111a and the outside, thereby improving the safety of the pressure cooker 1000. At the same time, the hollow portion 112b is also conducive to reducing the dead weight of the outer cover 11, so that the user can take the pressure cooker cover 100.

[0096] like Figure 2As shown, in a possible implementation, the valve assembly 20a further includes a valve sleeve 23 and an elastic member 24. The valve sleeve 23 is sleeved on the outside of the valve core 21, and the valve sleeve 23 can move relative to the valve core 21. An elastic member 24 is provided between the valve sleeve 23 and the valve core 21, and the elastic member 24 can be a spring, which is sleeved on the outside of the valve core 21. Along the axial direction Z of the pressure cooker 1000, one end of the elastic member 24 abuts against the valve sleeve 23, and the other end of the elastic member 24 abuts against the valve core 21.

[0097] The pressure limiting assembly 20 further includes an adjusting member 25, which is connected to one side of the valve sleeve 23. The adjusting member 25 is used to drive the valve sleeve 23 to move relative to the valve core 21 along the axial direction Z of the valve core 21, so as to deform the elastic member 24. The adjusting member 25 can be a knob, and by turning the knob, the valve sleeve 23 can be driven to move up and down to change the compression amount of the elastic member 24, thereby changing the magnitude of the force of the elastic member 24 acting on the valve core 21, so as to achieve the effect of pressure regulation.

[0098] Specifically, the adjusting member 25 can be preset to gear 0, gear 1 and gear 2. Gear 0 can be understood as neutral gear. When the adjusting member 25 is in gear 0, the valve core 21 blocks the pressure relief channel 272a, and the pressure in the pressure cooker 1000 can be normally increased. When the pressure value in the pressure cooker 1000 reaches A1 at gear 0, the valve core 21 is pushed up by the pressure to open the pressure relief channel 272a, so that the pressure cooker 1000 is relieved. By rotating the adjusting member 25 to make it in the first gear, during this process, the adjusting member 25 drives the valve sleeve 23 to move along the axial direction Z of the valve core 21 toward the side close to the pressure relief channel 272a to increase the compression of the elastic member 24. At this time, the force of the elastic member 24 acting on the valve core 21 becomes larger, resulting in the pressure value in the pressure cooker 1000 to rise to A2 (i.e., A2>A1) before the valve core 21 can be lifted up to release the pressure. That is, it can be understood that as the force of the elastic member 24 acting on the valve core 21 increases, the pressure value required to open the pressure relief channel 272a increases. Similarly, when the adjusting member 25 is rotated from the first gear to the second gear, the valve sleeve 23 further compresses the elastic member 24, thereby increasing the force of the elastic member 24 acting on the valve core 21. The pressure relief channel 272a can be opened only when the pressure value in the pressure cooker 1000 rises to A3 (i.e., A3>A2). In the above process, as the force of the elastic member 24 acting on the valve core 21 increases continuously, the pressure value required to open the pressure relief channel 272a also increases continuously, so that the pressure value of the pressure cooker 1000 during cooking increases continuously. For example, when the pressure cooker 1000 is in gear 3, the pressure cooker 1000 can perform normal pressure cooking at the pressure value of A1 or A2. The adjusting member 25 can adjust the pressure in the pressure cooker 1000 to increase gradually. Of course, according to the actual use needs of the pressure cooker 1000, the adjusting member 25 can also adjust the pressure in the pressure cooker 1000 to decrease gradually.

[0099] At present, the pressure limiting valve of the conventional pressure cooker does not have the pressure regulating function, which makes it difficult for the pressure cooker to meet the user's usage requirements. The pressure limiting assembly 20 of the embodiment of the present application has a pressure regulating function. By operating the adjusting member 25, the valve sleeve 23 is driven to move, thereby changing the force of the elastic member 24 acting on the valve core 21, and then changing the normal working pressure value in the pressure cooker 1000 to play a pressure regulating role. When the pressure cooker 1000 heats the food, the adjusting member 25 can be operated to adjust the pressure value of the pressure cooker 1000 according to the type of food to ensure the cooking effect of the pressure cooker 1000, that is, the pressure cooker 1000 meets the cooking needs of different foods, which is conducive to meeting the diverse usage needs of users and improving the user experience.

[0100] like Figure 6 As shown, one end of the adjusting member 25 can be connected to the handle 61, and the other end of the adjusting member 25 can pass through the handle cover 62 and extend in a direction away from the handle cover 62, so as to facilitate operation by the user.

[0101] like Figure 2 As shown, in a possible embodiment, the valve sleeve 23 includes a cavity 232, which extends along the axial direction Z of the valve core 21 and is connected to the outside. A protrusion 232a extending toward the inside of the cavity 232 is provided on the side wall of the cavity 232. The valve core 21 includes a main body 211, which is located in the cavity 232. The main body 211 has a boss 212 extending toward the side close to the valve sleeve 23 along the radial direction X of the valve core 21. Along the axial direction Z of the valve core 21, one end of the elastic member 24 abuts against the protrusion 232a, and the other end of the elastic member 24 abuts against the boss 212.

[0102] The protrusion 232a can be arranged along the circumference of the cavity 232, and the boss 212 can be arranged along the circumference of the main body 211 to increase the contact area with the elastic member 24. The above design is conducive to improving the stability of the connection between the elastic member 24 and the valve sleeve 23 and the valve core 21, so that the elastic member 24 provides a stable and reliable force for the valve core 21.

[0103] like Figure 5 As shown, in a possible implementation manner, the valve sleeve 23 has a first gear portion 231, and the first gear portion 231 is arranged on the outer circumferential surface of the valve sleeve 23. The adjusting member 25 has a second gear portion 251, and the second gear portion 251 is arranged on the outer circumferential surface of the adjusting member 25. The second gear portion 251 is meshed with the first gear portion 231. When the adjusting member 25 rotates relative to the valve sleeve 23, the adjusting member 25 is used to drive the valve sleeve 23 to rotate and move along the axial direction Z of the valve core 21.

[0104] The adjusting member 25 is connected to the valve sleeve 23 in a gear meshing manner, which is conducive to achieving a stable transmission relationship between the adjusting member 25 and the valve sleeve 23, and is conducive to the reliable pressure regulation function of the pressure cooker 1000. The user can adjust the pressure value in the pressure cooker 1000 by rotating the adjusting member 25, which simplifies the user's operation steps and reduces the difficulty of operation, thereby helping to improve the user's experience.

[0105] like Figure 1 and Figure 2 As shown, in a possible embodiment, the valve assembly 20a includes a valve bracket 27. The valve core 21 and the valve sleeve 23 are accommodated in the valve bracket 27. The valve bracket 27 is fixedly connected to the cover body 10. Specifically, the valve bracket 27 can be connected to the cover body 10 by fasteners such as screws (not shown in the figure). The valve bracket 27 is provided to improve the stability of the installation of the valve core 21 and the valve sleeve 23.

[0106] Specifically, if Figure 8 As shown, the outer circumference of the valve sleeve 23 is provided with a first threaded portion 233, and the inner circumference of the valve support 27 is provided with a second threaded portion 275. The first threaded portion 233 and the second threaded portion 275 cooperate to realize the threaded connection between the valve sleeve 23 and the valve support 27. As mentioned above, when the adjusting member 25 rotates relative to the valve sleeve 23, the adjusting member 25 drives the valve sleeve 23 to rotate and move along the axial direction Z of the valve core 21. Therefore, the valve sleeve 23 is threadedly connected with the valve support 27, so that the valve sleeve 23 can rotate relative to the valve support 27 and can also move relative to the valve support 27 along the axial direction Z of the valve core 21. At the same time, when the adjusting member 25 drives the valve sleeve 23 to move to a certain position, the first threaded portion 233 and the second threaded portion 275 cooperate with each other to keep the valve sleeve 23 at the position, that is, the valve sleeve 23 is limited, and the possibility of the valve sleeve 23 shaking up and down is reduced, which is conducive to improving the stability of the elastic member 24, so that the elastic member 24 applies a stable force to the valve core 21.

[0107] like Figure 2 and Figure 8 As shown, in a possible implementation, the valve bracket 27 includes a mounting portion 271 and a pressure relief portion 272, and along the axial direction Z of the valve core 21, the mounting portion 271 is connected above the pressure relief portion 272. The above-mentioned pressure relief channel 272a is arranged in the pressure relief portion 272. The mounting portion 271 has an installation space, and the valve sleeve 23 and the valve core 21 are accommodated in the installation space. Along the axial direction Z of the valve core 21, the valve sleeve 23 and the valve core 21 are used to abut against the bottom wall of the mounting portion 271, so as to limit the valve sleeve 23 and the valve core 21, and help to improve the stability of the valve sleeve 23 and the valve core 21 arranged on the valve bracket 27.

[0108] The end of the valve core 21 has a valve head 214. The bottom wall of the mounting portion 271 is provided with a valve head through hole 271a connected to the pressure relief channel 272a, and the valve head through hole 271a can extend along the axial direction Z of the valve core 21. The valve head 214 extends into the pressure relief channel 272a through the valve head through hole 271a to block the pressure relief channel 272a. The pressure relief channel 272a may have a first sealing member 30. The valve head 214 is provided with a mounting groove 214a along the radial direction X of the valve core 21, and the mounting groove 214a may be an annular groove arranged along the circumference of the valve core 21. The first sealing member 30 may be sleeved on the outer side of the valve head 214 and engaged with the mounting groove 214a to seal the valve head through hole 271a. The first sealing member 30 may be a sealing ring, and its material may be rubber or silicone. The first sealing member 30 seals the valve head perforation 271a to reduce the possibility of the steam in the pot leaking out through the valve head perforation 271a, thereby helping to improve the cooking effect of the pressure cooker 1000 and improving the safety of the pressure cooker 1000.

[0109] The embodiment of the present application provides a pressure relief portion 272 and a mounting portion 271 , which is beneficial for improving the stability and reliability of the installation of the valve core 21 and the valve sleeve 23 while achieving pressure increase and pressure relief of the pressure cooker 1000 .

[0110] like Figure 8 As shown, in a possible implementation, the pressure relief portion 272 includes a body portion 273 and a bottom cover 274 mounted on the body portion 273. The bottom cover 274 and the body portion 273 may be threadedly connected, or the bottom cover 274 and the body portion 273 may also be snap-connected.

[0111] The bottom cover 274 is provided with a steam inlet 274a extending along the axial direction Z of the valve core 21, and the steam in the pot enters the pressure relief channel 272a through the steam inlet 274a. The body 273 is provided with a steam outlet 273a extending along the radial direction X of the valve core 21. Specifically, the body 273 can be provided with a plurality of steam outlets 273a along its own circumference, and each steam outlet 273a is connected to each other and is connected to the steam inlet 274a. The above-mentioned steam inlet 274a is connected to the steam outlet 273a to form a pressure relief channel 272a. When the valve core 21 is located at the above-mentioned first position, the valve head 214 blocks the steam inlet 274a. At this time, the steam inlet 274a and the steam outlet 273a are not connected, and the pressure relief channel 272a is closed; when the valve core 21 is in the above-mentioned second position, the valve head 214 leaves the steam inlet 274a. At this time, the steam inlet 274a is connected to the steam outlet 273a, and the pressure relief channel 272a is opened.

[0112] In the embodiment of the present application, the steam inlet 274a is arranged on the bottom cover 274, and a complete pressure relief channel 272a is formed after the bottom cover 274 and the body 273 are assembled, thereby reducing the possibility of simultaneously opening the steam inlet 274a and the steam outlet 273a on the body 273, which is conducive to reducing the processing difficulty of the body 273 and improving the structural strength of the body 273. At the same time, the bottom cover 274 can be detachably connected to the body 273 to facilitate cleaning, maintenance or replacement of the bottom cover 274. For example, food residues in the pot are easy to enter the pressure relief channel 272a through the steam inlet 274a along with the steam. When the food residues accumulate in the steam inlet 274a and the pressure relief process is not smooth, the bottom cover 274 can be removed to clean the air inlet or directly replace a new bottom cover 274 to ensure normal pressure relief of the pressure cooker 1000, thereby improving the safety of the pressure cooker 1000.

[0113] like Fig. 9 As shown, in a possible implementation, the pressure relief portion 272 is connected to an anti-blocking cover 40. Specifically, the anti-blocking cover 40 can be threadedly connected to the pressure relief portion 272. The bottom cover 274 is located in the anti-blocking cover 40, and the anti-blocking cover 40 is provided with a connecting hole 41, which is connected to the steam inlet 274a.

[0114] The number of the connecting holes 41 can be multiple. As mentioned above, the food residue in the pot can easily enter the pressure relief channel 272a through the steam inlet 274a along with the steam. By providing the anti-blocking cover 40, the steam can enter the steam inlet 274a through the connecting hole 41, while filtering the food residue out, thereby reducing the possibility that the pressure relief channel 272a is blocked by food residue, resulting in an unsmooth pressure relief process or even failure to release pressure normally, which is conducive to improving the safety of the pressure cooker 1000.

[0115] like Figure 3 and Figure 7 As shown, in a possible embodiment, the cover body 10 includes an outer cover 11 and an inner cover 12 connected to the outer cover 11. The valve bracket 27 is connected to the outer cover 11 and the inner cover 12 respectively. Along the axial direction Z of the pressure cooker 1000, a pressure relief space 13 is formed between the outer cover 11 and the inner cover 12. The outer cover 11 is provided with a pressure relief hole 111a. The pressure relief space 13 is connected to the pressure relief channel 272a and the pressure relief hole 111a. The steam discharged from the pressure relief channel 272a first enters the pressure relief space 13 and then is discharged to the outside through the pressure relief hole 111a. In the process of pressure relief of the pressure cooker 1000, the steam discharged from the pressure relief channel 272a usually has a fast flow rate, and the pressure relief space 13 can play a buffering role on the steam, reducing the possibility of strong steam or liquid being discharged to the outside through the pressure relief hole 111a to cause safety hazards to users, thereby helping to improve the safety of the pressure cooker 1000.

[0116] The material of the inner cover 12 can be metal, and the inner cover 12 can be elastically deformed. The inner cover 12 is provided with a through hole, and the anti-blocking cover 40 passes through the inner cover 12 through the through hole and is connected to the inner cover 12 through the second sealing member 50. The second sealing member 50 can be a sealing ring, and its material can be rubber or silicone. Under the action of the pressure in the pot, the inner cover 12 can be elastically deformed toward the side close to the outer cover 11. At this time, since the anti-blocking cover 40 is connected to the pressure relief portion 272 of the valve bracket 27 (such as Fig. 9 As shown in the figure, it will not move with the inner cover 12, so a pressure relief gap connected to the pressure relief space 13 is generated between the inner cover 12 and the second sealing member 50, and the steam in the pot can enter the pressure relief space 13 through the pressure relief gap, and then be discharged to the outside through the pressure relief hole 111a, thereby playing a role of rapid pressure relief, reducing the possibility of explosion caused by continuous increase in internal pressure of the pressure cooker 1000 due to untimely pressure relief, thereby helping to improve the safety and reliability of the pressure cooker 1000. When the pressure value in the pot returns to the normal range, the inner cover 12 can return to its initial shape and connect to the second sealing member 50 to ensure that the pressure cooker 1000 works normally.

[0117] like Fig.10 As shown, in a possible embodiment, the pot body 200 includes pot teeth 201, which protrude toward the inside of the pot body 200. The outer cover 11 has pot cover teeth 114, which protrude toward the outside of the outer cover 11. When the pressure cooker lid 100 is buckled on the pot body 200, the pot teeth 201 can cooperate with the pot cover teeth 114, so that the pressure cooker lid 100 is locked on the pot body 200.

[0118] like Fig.11As shown, the pressure cooker lid 100 includes a stop opening assembly 70, which is mounted on the inner cover 12. The stop opening assembly 70 includes a float 71 and a lock 72, and the lock 72 passes through the inner cover 12 and the outer cover 11, that is, one end of the lock 72 can be located outside the outer cover 11 and can contact the pot teeth 201. Under the action of the pressure in the pot, the float 71 can move up and down along the axial direction Z of the pressure cooker 1000. When the pressure value in the pot is within a preset range, the float 71 is in a first state of sinking. At this time, the pressure cooker lid 100 is rotated, and the lock 72 can move in the radial direction X of the pressure cooker lid 100 in a direction away from the pot body 200 under the push of the pot teeth 201, so as to release the limit between the pressure cooker lid 100 and the pot body 200, so as to facilitate opening the pressure cooker lid 100. When the pressure value in the pot rises and exceeds the above-mentioned preset range, the float 71 is in the second state of floating up under the action of pressure. At this time, the lock buckle 72 is limited by the float 71 in the radial X direction of the pressure cooker cover 100. Even if the pressure cooker cover 100 is rotated to make the pot teeth 201 apply thrust to the lock buckle 72, the lock buckle 72 cannot move due to the obstruction of the float 71, thereby limiting the position of the pressure cooker cover 100 on the pot body 200 and the pressure cooker cover 100 cannot be opened.

[0119] In the embodiment of the present application, the pressure cooker 1000 is provided with a stop-opening assembly 70, which helps to reduce the possibility of the user being scalded by high-temperature steam due to the lid being opened by mistake during the cooking process, thereby helping to improve the safety of the pressure cooker 1000.

[0120] Continue to refer Fig.11 Further, the stop opening assembly 70 also includes a stop opening bracket 73, a return spring 74, a stop opening bracket sealing ring 75 and a float sealing ring 76. The stop opening bracket 73 is installed on the inner cover 12. The stop opening bracket 73 is provided with a float hole for installing the float 71 and a lock hole for installing the lock buckle 72. The float sealing ring 76 is sleeved on the outer side of the float 71 to seal the hole of the float 71. The stop opening bracket sealing ring 75 is sleeved on the outer side of the stop opening bracket 73 and the lock buckle 72 to seal the hole of the lock buckle 72. The return spring 74 is sleeved on the lock buckle 72, and along the radial direction X of the pressure cooker pot cover 100, one end of the return spring 74 is connected to the stop opening bracket 73, and the other end of the return spring 74 is connected to the lock buckle 72. When the lock buckle 72 is pushed by the pot teeth 201 and retracts toward the inside of the inner cover 12, the return spring 74 is compressed. When the lock catch 72 is not pressed by the pot teeth 201 , the lock catch 72 moves toward the outside of the inner cover 12 under the action of the return spring 74 .

[0121] The anti-opening assembly 70 provided in the embodiment of the present application has good sealing performance, which is conducive to improving the reliability of the anti-opening assembly 70. At the same time, by providing a reset spring 74, it is conducive to achieving automatic reset of the lock buckle 72, thereby achieving repeated use of the lock buckle 72, thereby improving the convenience of using the anti-opening assembly 70.

[0122] The working process of the stopper assembly 70 is as follows: before the pressure cooker 1000 is used for cooking, the pressure cooker lid 100 is closed onto the pot body 200. At this time, the pressure cooker 1000 is not pressurized and the float 71 is in the first state. At this time, the pressure cooker lid 100 is rotated, and the lock buckle 72 moves along the radial direction X of the pressure cooker lid 100 in a direction away from the pot body 200 under the push of the pot teeth 201. When the pressure cooker lid 100 is rotated into place, the pot teeth 201 on the pot body 200 cooperate with the pot cover teeth 114 on the pressure cooker lid 100, and the lock buckle 72 loses the function of the pot teeth 201 and pops out under the action of the reset spring 74. When the pressure cooker 1000 is cooking, the pressure value in the pot increases, and the float 71 floats up to the second state under the action of the pressure. At this time, the lock buckle 72 cannot retract inwards under the limiting action of the float 71, that is, the lock buckle 72 plays a limiting role between the pressure cooker lid 100 and the pot body 200, preventing the pressure cooker lid 100 from being opened when the pressure cooker 1000 is cooking. After the pressure cooker 1000 finishes cooking, the pressure value in the pot decreases, and the float 71 returns to the first state, that is, the limiting action of the float 71 on the lock buckle 72 is released. At this time, the pressure cooker lid 100 is rotated, and the lock buckle 72 retracts inwards again under the push of the pot teeth 201. The pressure cooker lid 100 is continuously rotated until the pot teeth 201 are disengaged from the pot cover teeth 114, thereby releasing the limiting action between the pressure cooker lid 100 and the pot body 200, and facilitating the opening of the pressure cooker lid 100.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
