Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a pressure cooker cover and a pressure cooker. Background Art

[0002] A pressure cooker is a common cooking appliance. Its main function is to increase the heating temperature by increasing the gas pressure in the pot, thereby increasing the heating speed. The pressure cooker is mainly composed of a pressure cooker lid and a pot body. The pressure cooker lid and the pot body are fixed to each other by means of buckles, etc. The pressure cooker lid is usually equipped with a pressure limiting valve to release the pressure in the pot.

[0003] In the prior art, it is difficult to control the exhaust speed during the venting and pressure reduction process of the pressure cooker lid. When cooking liquid ingredients such as porridge or soup, the liquid in the pot is likely to overflow during the venting process, causing contamination of the pressure cooker or countertop, affecting the user experience of the pressure cooker. Utility Model Content

[0004] The present application provides a pressure cooker cover and a pressure cooker, so as to control the exhaust speed of a pressure limiting valve as required, prevent liquid from overflowing during the exhaust process, and improve the user experience of the pressure cooker.

[0005] The first aspect of the present application provides a pressure cooker cover, comprising:

[0006] The cover body is provided with an exhaust hole;

[0007] a pressure limiting valve, facing the exhaust hole and capable of sliding along the axial direction of the exhaust hole to open or close the exhaust hole;

[0008] A stepped seat is arranged above the cover body, and the stepped seat gradually increases or decreases along the circumferential height of the pressure limiting valve;

[0009] An operating handle is connected to the pressure limiting valve, the operating handle protrudes from one side of the pressure limiting valve along the radial direction of the pressure limiting valve, and the operating handle can rotate around the axis of the exhaust hole and overlap the stepped seat to keep the exhaust hole in an open state.

[0010] The pressure cooker lid provided by the present application includes a lid body, a pressure limiting valve, a stepped seat, and an operating handle; the lid body is provided with an exhaust hole, the pressure limiting valve is opposite to the exhaust hole and can slide along the axial direction of the exhaust hole to open or close the exhaust hole, so as to limit the maximum pressure in the pot, meet the high-pressure requirements during the cooking process, and the exhaust and pressure relief requirements after cooking; the stepped seat is arranged above the lid body, and the circumferential height of the stepped seat gradually increases or gradually decreases along the pressure limiting valve, so as to form at least two platforms with different heights around the pressure limiting valve; the operating handle is connected to the pressure limiting valve and protrudes radially from one side of the pressure limiting valve, and the operating handle can rotate around the axis of the exhaust hole and lap on the stepped seat to keep the exhaust hole open. After cooking, the user lifts the pressure limiting valve through the operating handle to achieve exhaust and pressure relief. The operating handle can avoid the ejection area of the exhaust hole to prevent scalding the user. By lapping the operating handle on the support seat, the exhaust hole can still maintain the exhaust state after the user releases the operating handle, improving the convenience and safety of use. Moreover, by lapping the operating handle on platforms with different heights, the opening degree of the exhaust hole can be adjusted, so as to control the exhaust speed of the pressure limiting valve as needed, prevent liquid overflow during the exhaust process, and improve the use experience of the pressure cooker. In addition, using the operating handle to support the pressure limiting valve eliminates the need to set up a special support structure on the pressure limiting valve, which can simplify the structure of the pressure limiting valve.

[0011] Optionally, the lid body is provided with an installation hole, and the pressure cooker lid further includes a safety valve, and the safety valve passes through the installation hole; in the natural state, the safety valve closes the installation hole, and the exhaust and pressure relief are realized by opening the exhaust hole through the pressure limiting valve; when the pressure is too high, the safety valve opens the installation hole, that is, when the exhaust hole is blocked or otherwise abnormal and cannot exhaust normally, the pressure in the pot will rise rapidly, and the exhaust and pressure relief are carried out through the installation hole, so as to play a safety protection role and prevent dangerous situations such as explosion due to too high pressure in the pot.

[0012] Optionally, the pressure cooker lid further includes an elastic support seat, and the support seat is arranged above the lid body and connects the lid body and the safety valve; in the natural state, the safety valve is in sealed cooperation with the upper side of the lid body to close the installation hole; when the pressure is too high, the safety valve rises to open the installation hole, and the support seat deforms in a direction away from the lid body along with the safety valve. By deforming the support seat, the lifting stroke of the support seat is limited, making the movement of the safety valve more stable, and it can also prevent parts such as the safety valve from popping out under the impact of high-pressure gas, improving the safety of using the pressure cooker lid. In addition, after the pressure in the pot drops to the normal range, the support seat can automatically recover its deformation to make the safety valve close the installation hole, eliminating the need to replace parts and reducing the use cost and maintenance cost of the pressure cooker.

[0013] Optionally, the support base is arranged as a thin sheet-like structure extending along the radial direction of the lid body. The support base can be bent and deformed along its own thickness direction to have elasticity; the support bases are stacked on one side of the lid body. This can reduce the overall thickness of the pressure cooker lid, improve the compactness of the overall structure of the pressure cooker lid, and reduce the overall volume of the pressure cooker lid.

[0014] Optionally, a groove is provided at the top of the lid body, the support base is arranged in the groove, the pressure cooker lid further includes a lid head, the lid head is detachably connected to the lid body or the support base, and the lid head covers the groove. This can not only reduce the overall height of the lid body, thereby reducing the overall volume of the pressure cooker lid and improving the compactness of the structure of the pressure cooker lid, but also enable components such as the support base and the safety valve to be hidden inside the pressure cooker lid, thereby improving the appearance of the pressure cooker lid.

[0015] Optionally, the exhaust hole is arranged outside the area of the groove. On the one hand, the exhaust hole only needs to penetrate through the lid body with a smaller thickness, which can reduce the axial length of the exhaust hole and reduce the risk of blockage of the exhaust hole; on the other hand, the gas is discharged on the exposed surface of the lid body, preventing the liquid generated by gas condensation from remaining inside the pressure cooker lid and affecting the cleanliness of the use of the pressure cooker lid.

[0016] Optionally, the stepped seat is integrally formed on the edge of the lid head. On the one hand, the original structure of the lid body is basically unchanged, simplifying the processing technology of the lid body; on the other hand, since the lid head is generally made of heat-insulating material, and the stepped seat is integrally formed with the lid head, the stepped seat plays a heat-insulating role under the operating handle, preventing the operating handle from directly contacting the lid body and overheating.

[0017] Optionally, the pressure limiting valve includes a sealing part and a guide rod. The guide rod penetrates through the exhaust hole and forms an annular gap with the exhaust hole. The sealing part is located above the exhaust hole to open or close the annular gap. The exhaust hole serves as the guiding structure of the pressure limiting valve, which can not only improve the relative position accuracy between the pressure limiting valve and the exhaust hole, ensure that the pressure limiting valve can accurately close the exhaust hole, but also enable a part of the pressure limiting valve to sink into the inside of the lid body, thereby reducing the overall height of the pressure limiting valve and improving the compactness of the overall structure of the pressure cooker lid.

[0018] Optionally, the pressure limiting valve includes a weight part. The weight part is located below the lid body, and the weight part is connected to the guide rod. By arranging the weight part inside the lid body, the weight of the pressure limiting valve is increased, which can reduce the volume of the pressure limiting valve exposed outside the lid body, thereby further improving the structural compactness of the pressure cooker lid and improving the appearance of the pressure cooker lid.

[0019] The second aspect of the present application provides a pressure cooker, which includes a pot body and any one of the pressure cooker lids provided by the present application, wherein the pressure cooker lid is movably connected to the pot body and can be sealed with the pot body. After cooking is finished, the user lifts the pressure limiting valve through an operating handle to exhaust and release pressure, and the operating handle can avoid the spraying area of the exhaust hole to prevent scalding the user. By overlapping the operating handle with the support seat, the exhaust hole can still maintain the exhaust state after the user releases the operating handle, thereby improving the convenience and safety of use, and by overlapping the operating handle with platforms of different heights, the opening size of the exhaust hole can be adjusted, thereby controlling the exhaust speed of the pressure limiting valve as needed, preventing liquid from overflowing during the exhaust process, and improving the user experience of the pressure cooker.

[0055] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments in line with the present application, and are used together with the specification to explain the principles of the present application. Detailed implementation manners

[0056] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further details the present application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] In the description of the present application, unless otherwise clearly specified or limited, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "plurality" means two or more; the terms "connection", "fixation", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0058] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0059] As Figures 1 - 3 shown, the embodiments of the present application also provide a pressure cooker, which includes a pot body 10 and a pressure pot lid 20. The pressure pot lid 20 is movably connected to the pot body 10 and can be hermetically fitted with the pot body 10 so that high pressure can be generated inside the pot to meet the high-pressure cooking requirements. Among them, a plurality of first pot teeth 10a can be convexly provided on the inner wall of the pot body 10, and the first pot teeth 10a are arranged at intervals along the circumferential direction of the pot body 10; second pot teeth 20a can be convexly provided on the outer wall of the lid body 1, and the second pot teeth 20a are arranged at intervals along the circumferential direction of the lid body 1. When the pressure pot lid 20 needs to be covered on the pot body 10, the second pot teeth 20a face the intervals between the first pot teeth 10a, and the pressure pot lid 20 is moved downward from top to bottom; when the pressure pot lid 20 moves into place, the pressure pot lid 20 is rotated so that the second pot teeth 20a are blocked below the first pot teeth 10a, thereby realizing the installation and fixation of the pressure pot lid 20.

[0060] As Figures 3 - 5 shown, the pressure pot lid 20 provided by the embodiments of the present application includes a lid body 1 and a pressure-limiting valve 2. The lid body 1 is provided with an exhaust hole 11, and the pressure-limiting valve 2 faces the exhaust hole 11 and can slide along the axial direction of the exhaust hole 11 to open or close the exhaust hole 11, thereby limiting the maximum pressure inside the pot to meet the high-pressure requirements during the cooking process and the exhaust pressure relief requirements after the cooking is completed. Specifically, when the pressure-limiting valve 2 closes the exhaust hole 11, a sealed state is formed inside the pot, so that the pressure inside the pot can rise to meet the high-pressure cooking requirements; when the pressure-limiting valve 2 opens the exhaust hole 11, a pressure relief state is formed inside the pot, and the gas inside the pot quickly discharges from the exhaust hole 11. On the one hand, it prevents the pressure inside the pot from being too high during the cooking process, and on the other hand, it realizes exhaust pressure relief after the cooking is completed.

[0061] Furthermore, the pressure cooker lid 20 provided by the embodiments of the present application further includes a stepped seat 3 and an operating handle 4. The stepped seat 3 is disposed above the lid body 1. The stepped seat 3 ascends and descends along the circumference of the pressure limiting valve 2, thereby forming at least two platforms with different heights around the pressure limiting valve 2. The operating handle 4 is connected to the pressure limiting valve 2 and protrudes radially from one side of the pressure limiting valve 2. After cooking is completed, the user lifts the pressure limiting valve 2 by holding the operating handle 4 to achieve exhaust pressure relief. The operating handle 4 can avoid the ejection area of the exhaust hole 11, preventing scalding the user. The operating handle 4 can rotate around the axis of the exhaust hole 11 and lap on the stepped seat 3, so that the exhaust hole 11 remains open. That is to say, after the user releases the operating handle 4, the exhaust hole 11 can still maintain the exhaust state, improving the convenience and safety of use. Moreover, by lapping the operating handle 4 on platforms with different heights, the opening degree of the exhaust hole 11 can be adjusted, thereby controlling the exhaust speed of the pressure limiting valve 2 as needed, preventing liquid from overflowing during the exhaust process, and improving the use experience of the pressure cooker. In addition, by using the operating handle 4 to support the pressure limiting valve 2, there is no need to provide a special support structure on the pressure limiting valve 2, which can simplify the structure of the pressure limiting valve 2.

[0062] Specifically, the stepped seat 3 can be directly connected to the lid body 1, or can be indirectly connected to the lid body 1 through other components, as long as the stepped seat 3 is located above the lid body 1 and the stepped seat 3 ascends and descends along the circumference of the pressure limiting valve 2. When the stepped seat 3 is directly connected to the lid body 1, the stepped seat 3 can be integrally formed on the surface of the lid body 1, or the stepped seat 3 can be fixed to the surface of the lid body 1 by means of bonding or screws.

[0063] Furthermore, the operating handle 4 and the pressure limiting valve 2 are provided as two independent components. A connecting portion 41 can be provided at one end of the operating handle 4 facing the pressure limiting valve 2. The connecting portion 41 is sleeved on the pressure limiting valve 2 and forms a detachable connection with the pressure limiting valve 2, so that the operating handle 4 and the pressure limiting valve 2 are connected to form a whole, thereby simplifying the structure of the pressure limiting valve 2 and improving the processing precision of the pressure limiting valve 2. In addition, the operating handle 4 can also be made of a heat-insulating material, which can not only reduce the weight of the operating handle 4, but also avoid scalding caused by the overheating of the operating handle 4. It can be understood that in other embodiments, the operating handle 4 and the pressure limiting valve 2 can also be integrally formed.

[0064] Specifically, when the operating handle 4 and the pressure limiting valve 2 are provided as two independent components, the pressure limiting valve 2 and the operating handle 4 are axially relatively fixed to ensure that the pressure limiting valve 2 can ascend and descend synchronously with the operating handle 4 to adjust the opening degree of the exhaust hole 11. The pressure limiting valve 2 and the operating handle 4 can be circumferentially relatively fixed, that is, the pressure limiting valve 2 rotates and ascends and descends synchronously with the operating handle 4; or the operating handle 4 can be rotatably connected to the pressure limiting valve 2, that is, the operating handle 4 rotates independently, and the pressure limiting valve 2 only ascends and descends axially with the operating handle 4.

[0065] Furthermore, the pressure limiting valve 2 includes a sealing portion 21 and a guide rod 22. The guide rod 22 passes through the exhaust hole 11 and forms an annular gap with the exhaust hole 11. The sealing portion 21 is located above the exhaust hole 11 to open or close the annular gap. The exhaust hole 11 serves as a guiding structure for the pressure limiting valve 2, which can not only improve the relative position accuracy between the pressure limiting valve 2 and the exhaust hole 11 to ensure that the pressure limiting valve 2 can accurately close the exhaust hole 11, but also allow a part of the pressure limiting valve 2 to sink into the interior of the cover body 1, thereby reducing the overall height of the pressure limiting valve 2 and improving the compactness of the overall structure of the pressure cooker lid 20. It can be understood that in other embodiments, a dedicated guiding structure can also be provided on the surface of the cover body 1.

[0066] Furthermore, a conical surface or an arc surface can be provided on the side of the sealing portion 21 facing the exhaust hole 11 to form a sealing fit with the exhaust hole 11 through the conical surface or the arc surface. On the one hand, the sealing area can be reduced, and the reliability of the sealing fit can be increased; on the other hand, it can play an automatic centering role to prevent the pressure limiting valve 2 from deviating from the exhaust hole 11 and affecting the sealing effect.

[0067] Furthermore, the sealing portion 21 and the guide rod 22 are integrally formed. This can not only reduce the machining error and improve the accuracy of the pressure limiting valve 2 itself, but also reduce the number of components and lower the production cost. It can be understood that in other embodiments, the sealing portion 21 and the guide rod 22 can also be provided as two separate components and connected into a whole by means of threaded cooperation or the like.

[0068] Furthermore, the pressure limiting valve 2 includes a counterweight portion 23. The counterweight portion 23 is located below (i.e., inside) the cover body 1, and the counterweight portion 23 is connected to the guide rod 22. By providing the counterweight portion 23 inside the cover body 1 to increase the weight of the pressure limiting valve 2, the volume of the pressure limiting valve 2 exposed outside the cover body 1 can be reduced, thereby further improving the structural compactness of the pressure cooker lid 20 and improving the appearance of the pressure cooker lid 20.

[0069] Furthermore, the counterweight portion 23 can be provided as a circular columnar structure with a larger diameter and a smaller height to minimize the distance that the counterweight portion 23 extends downward and prevent the liquid or foam in the pot from coming into contact with the counterweight portion 23, resulting in problems such as pollution or weight change of the counterweight portion 23. It can be understood that in other embodiments, the counterweight portion 23 can also be provided in other shapes according to needs, for example, a conical or polygonal column.

[0070] Specifically, the counterweight portion 23 is sleeved on the outer periphery of the guide rod 22. An axial fixing structure such as a buckle, a circlip or a nut can be provided below the counterweight portion 23 to provide an axial supporting effect on the counterweight portion 23, so that the counterweight portion 23 can be stably installed on the guide rod 22. In addition, the counterweight portion 23 is detachably connected to the guide rod 22, which can facilitate the disassembly and cleaning of the pressure limiting valve 2.

[0071] Further, there is a gap between the top surface of the counterweight portion 23 and the lower surface of the cover body 1 to provide a movement stroke for the pressure limiting valve 2 along the axial direction of the exhaust hole 11, avoiding interference between the counterweight portion 23 and the cover body 1, which may cause the pressure limiting valve 2 to be unable to open the exhaust hole 11 normally. The counterweight portion 23 can stop against the lower surface of the cover body 1, playing an axial limiting role for the pressure limiting valve 2 to prevent the pressure limiting valve 2 from falling off the valve body.

[0072] Further, at least one of the top surface of the counterweight portion 23 and the lower surface of the cover body 1 is provided with limiting protrusions 231. The number of the limiting protrusions 231 is not less than two, and the limiting protrusions 231 are arranged at intervals around the axis of the counterweight portion 23. An exhaust gap is formed between adjacent limiting protrusions 231 to prevent the counterweight portion 23 and the cover body 1 from fitting together to close the exhaust hole 11, affecting the normal discharge of gas.

[0073] Specifically, the limiting protrusions 231 can be set into any appropriate structures such as convex dots or strips. When the limiting protrusions 231 are set as strips, the limiting protrusions 231 can extend along the radial direction of the counterweight portion 23, or the limiting protrusions 231 can also extend along the circumferential direction of the counterweight portion 23.

[0074] As Figures 3 - 7 shown, the pressure cooker lid 20 provided by the embodiment of the present application further includes a safety valve 5. The cover body 1 is provided with an installation hole 12, and the safety valve 5 is inserted through the installation hole 12. In the natural state, the safety valve 5 closes the installation hole 12, and the exhaust hole 11 is opened by the pressure limiting valve 2 to achieve exhaust pressure relief. When the exhaust hole 11 is blocked or otherwise abnormal and cannot exhaust normally, the pressure inside the pot will rise rapidly. When the pressure is too high, the safety valve 5 opens the installation hole 12, and exhaust pressure relief is carried out through the installation hole 12, thereby playing a safety protection role to prevent dangerous situations such as explosion due to too high pressure inside the pot.

[0075] Further, the pressure cooker lid 20 provided by the embodiment of the present application further includes an elastic support seat 6. The support seat 6 is arranged above the cover body 1, connecting the cover body 1 and the safety valve 5 to realize the installation and fixation of the safety valve 5. In the natural state, the safety valve 5 is in sealing cooperation with the upper side of the cover body 1 (for example, conical surface sealing, etc.) to close the installation hole 12; when the pressure is too high, the safety valve 5 rises to open the installation hole 12, and the support seat 6 deforms in a direction away from the cover body 1 along with the safety valve 5. The lifting stroke of the support seat 6 is limited by the deformation of the support seat 6, making the movement of the safety valve 5 more stable. It can also prevent components such as the safety valve 5 from popping out under the impact of high-pressure gas, improving the safety of using the pressure cooker lid 20. In addition, after the pressure inside the pot drops to the normal range, the support seat 6 can automatically recover its deformation, making the safety valve 5 close the installation hole 12, without the need to replace components, reducing the use cost and maintenance cost of the pressure cooker.

[0076] Further, the safety valve 5 is provided with a seal 51, and the seal 51 can be made of an elastic material such as silica gel or rubber. The safety valve 5 forms a sealing fit with the cover body 1 through the elastic seal 51, so as to reduce the requirement for the fitting accuracy between the safety valve 5 and the cover body 1 and reduce the production cost.

[0077] Further, a mounting portion 52 protrudes from the bottom of the safety valve 5, and the seal 51 is sleeved on the mounting portion 52. The mounting portion 52 passes through the mounting hole 12 to form a radial limit for the seal 51; an annular limit groove 53 is provided on the outer periphery of the mounting portion 52, and the seal 51 is installed in the limit groove 53 to form an axial limit for the seal 51; the seal 51 elastically abuts against the upper side of the cover body 1, thereby realizing the sealing fit between the seal 51 and the mounting hole 12.

[0078] Further, the support seat 6 is arranged as a thin sheet-like structure extending along the radial direction of the cover body 1. The support seat 6 can be bent and deformed along its own thickness direction to have elasticity. The support seats 6 are stacked on one side of the cover body 1 to reduce the overall thickness of the pressure cooker lid 20, improve the compactness of the overall structure of the pressure cooker lid 20, and reduce the overall volume of the pressure cooker lid 20. For example, the support seat 6 can be arranged as a strip-like structure extending along the radial direction of the cover body 1, or the support seat 6 can be arranged as a circular sheet-like structure, etc. It can be understood that in other embodiments, elastic members such as springs can also be arranged in the support seat 6 to make the support seat 6 have elasticity as a whole.

[0079] Specifically, the support seats 6 can be stacked above the cover body 1, or the support seats 6 can be stacked below the cover body 1. The support seat 6 and the cover body 1 can be detachably connected to each other by means such as screws or buckles, or can be integrally formed in a non-detachable manner. Similarly, the support seat 6 and the safety valve 5 can be detachably connected to each other by means such as screws or buckles, or can be integrally formed in a non-detachable manner.

[0080] Further, the support seats 6 are stacked above the cover body 1, and a groove 13 is provided at the top of the cover body 1. The support seat 6 is arranged in the groove 13 to reduce the overall height of the cover body 1, thereby reducing the overall volume of the pressure cooker lid 20 and improving the compactness of the structure of the pressure cooker lid 20.

[0081] Further, the pressure cooker lid 20 further includes a cover head 7, and the user lifts the pressure cooker lid 20 by holding the cover head 7. The cover head 7 covers the groove 13, so that components such as the support seat 6 and the safety valve 5 are hidden inside the pressure cooker lid 20, thereby improving the appearance of the pressure cooker lid 20. The cover head 7 is detachably connected to the cover body 1 or the support seat 6 to facilitate the maintenance or replacement of internal components such as the safety valve 5.

[0082] Specifically, one end of the lid 7 facing the lid body 1 can be provided with a movable buckle 71, and the lid body 1 or the support base 6 can be provided with a clamping groove 61. In the natural state, the movable buckle 71 and the clamping groove 61 are locked with each other, and the lid 7 is stably installed and fixed on the lid body 1; when the user applies an external force to the movable buckle 71, the movable buckle 71 and the clamping groove 61 are disengaged from the lock, and the lid 7 can be disassembled and removed. The movable buckle 71 is connected with a buckle release portion 72, and at least a part of the buckle release portion 72 is exposed outside the lid 7. Driving the movable buckle 71 to disengage from the clamping groove 61 through the buckle release portion 72 can make the operation more convenient and labor-saving, and improve the convenience of the operation.

[0083] Further, the exhaust hole 11 is arranged outside the area of the groove 13. On the one hand, the exhaust hole 11 only needs to penetrate through the lid body 1 with a smaller thickness, which can reduce the axial length of the exhaust hole 11 and reduce the risk of blockage of the exhaust hole 11; on the other hand, the gas is discharged on the surface of the exposed lid body 1, preventing the liquid generated by gas condensation from remaining inside the pressure cooker lid 20 and affecting the cleanliness of the use of the pressure cooker lid 20.

[0084] Wherein, the lid body 1 can be provided with a boss 14 and other structures around the exhaust hole 11, which can not only improve the local strength of the lid body 1, prevent damage such as deformation or cracking at the edge of the exhaust hole 11, but also form a mating surface with higher precision, and improve the mating precision between the pressure limiting valve 2 and the exhaust hole 11.

[0085] Further, the stepped seat 3 is integrally formed at the edge of the lid 7, and the stepped seat 3 is connected to the upper surface of the lid body 1 through the lid 7. On the one hand, the original structure of the lid body 1 is basically unchanged, simplifying the processing technology of the lid body 1; on the other hand, since the lid 7 is generally made of a heat-insulating material, and the stepped seat 3 is integrally formed with the lid 7, the stepped seat 3 plays a heat-insulating role below the operating handle 4, preventing the operating handle 4 from directly contacting the lid body 1 and overheating.
