[0003] The pressure cooker in the related art generally needs to be sealed between the pot cover and the pot body with a seal. When the pot cover is thick, it is not easy to form the installation position of the seal through the shrinking process, and when the pot cover is thin, its own strength is poor. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model provides a pot cover and a pressure cooker, which have the advantages of being easy to seal and having a high pot cover strength.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pot cover comprises a sealing member, an outer cover and an inner cover laminated and fixed to the outer cover, wherein the edge of the inner cover extends in a direction away from the outer cover to form an installation space between the edge of the outer cover and the edge of the inner cover, and the sealing member is installed in the installation space.

[0007] Optionally, the edge of the inner cover is configured as a first oblique straight section inclined in a direction away from the outer cover, and the first oblique straight section and the outer cover are combined to form the installation space.

[0008] Optionally, the first oblique straight section is configured as a ring, the sealing member is configured as a sealing ring, and the sealing member is sleeved on a side surface of the first oblique straight section close to the outer cover.

DETAILED DESCRIPTION

[0033] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0034] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] Example:

[0036] This embodiment provides a pot cover, such as Figures 1 to 3 As shown, it includes a sealing member 3, an outer cover 1, and an inner cover 2 stacked and fixed on the outer cover 1, the edge of the inner cover 2 extends in a direction away from the outer cover 1 to form an installation space 4 between the outer cover 1 and the inner cover 2, and the sealing member 3 is installed in the installation space 4.

[0037] The pot cover produces tangential shrinkage plastic deformation under the action of axial force, and finally forms a reduced end diameter. When the pot cover is thick, it is difficult to form the installation position of the seal 3 using the traditional shrinking process. The thicker material may not easily reach the required shape and size during the shrinking process, thereby affecting the installation and sealing effect of the seal 3. When the pot cover is thin, its own strength is poor. During the high-pressure or high-temperature cooking process, the pot cover may be easily deformed or damaged, thereby affecting the sealing effect and service life. In this embodiment, a pot cover suitable for use on a pressure cooker is provided, which includes an outer cover 1, an inner cover 2 and a seal 3. The outer cover 1 and the inner cover 2 are stacked, and the edge of the inner cover 2 extends in a direction away from the outer cover 1, so that an installation space 4 capable of accommodating the seal 3 is reserved between the inner cover 2 and the outer cover 1, which is convenient for improving the sealing effect of the pressure cooker. And because the pot cover is configured as a double-layer, compared with a single-layer pot cover, the thickness of the inner cover 2 and the outer cover 1 in this embodiment can be appropriately reduced to facilitate the necking process, and the inner cover 2 and the outer cover 1, both of which are relatively thin, can cooperate to improve the strength of the pot cover as a whole. That is, the inner cover 2 and the outer cover 1 provide additional structural support and stability. Although the thickness of the inner cover 2 and the outer cover 1 may be relatively thin when viewed separately, their combination can meet or exceed the requirements of the single-layer pot cover in terms of strength, rigidity and sealing. In addition, the inner cover 2 and the outer cover 1 can be made of different materials, such as the inner cover 2 is made of food-grade metal, and the outer cover 1 is made of ordinary metal, so as to save the production cost of the pot cover.

[0038] like Figure 4As shown, the edge of the inner cover 2 is configured as a first oblique straight section 21 inclined in a direction away from the outer cover 1 , and the first oblique straight section 21 and the outer cover 1 enclose a mounting space 4 .

[0039] In this embodiment, the first oblique straight section 21 of the edge of the inner cover 2 is inclined in a direction away from the outer cover 1, providing sufficient installation space 4 for the seal 3, ensuring that the seal 3 can fit tightly between the pot body and the pot cover after installation, thereby enhancing the sealing effect. The space enclosed by the first oblique straight section 21 and the outer cover 1 is the installation space 4, which is used to install the seal 3, such as silica gel or rubber ring, etc. After installation, the seal 3 is compressed in this space. When the pot cover is closed, the seal 3 is squeezed by the pot body and the inner cover 2 and the outer cover 1 to form a tight seal. In other embodiments, the edge of the inner cover 2 can also be constructed as a curved section, a wavy section, etc. inclined in the direction of the outer cover 1, which is not limited here.

[0040] The first oblique straight section 21 is configured in a ring shape, and the sealing member 3 is configured in a sealing ring. The sealing member 3 is sleeved on a side surface of the first oblique straight section 21 close to the outer cover 1 .

[0041] In the present embodiment, the first oblique straight section 21 is constructed as an annular shape, that is, the first oblique straight section 21 extends around the entire edge of the inner cover 2, ensuring that no matter at which angle or direction the pot cover is placed, it can form a uniform seal with the pot body. The annular design also enhances the structural strength of the pot cover, making it more durable. The seal 3 is constructed as a soft and elastic sealing ring, usually made of silicone, rubber or other similar materials. The sealing ring is sleeved on a side surface of the first oblique straight section 21 close to the outer cover 1. When the pot cover is covered on the pot body, the sealing ring will be compressed between the pot body and the inner cover 2 and the outer cover 1 to form a tight sealing interface. In other embodiments, the first oblique straight section 21 can also be constructed as an arc section, and a plurality of first oblique straight sections 21 of arc structure are distributed around the periphery of the inner cover 2 in an equidistant or unequally spaced manner.

[0042] The outer cover 1 includes, in a direction away from its central axis, a second oblique straight section 11 that fits with the edge of the inner cover 2 , a straight section 12 that abuts against the seal 3 , and a flange 13 that extends away from the inner cover 2 .

[0043] In this embodiment, the second oblique straight section 11 of the outer cover 1 is used to fit tightly with the first oblique straight section 21 of the inner cover 2, which enhances the overall structural strength of the pot cover and ensures the sealing performance between the inner cover 2 and the outer cover 1. Due to the mutual cooperation of the two oblique straight sections, the pot cover can form a stable sealing surface when it is closed. The straight section 12 is located behind the second oblique straight section 11 and abuts against the seal 3. When the pot cover is closed, a part of the sealing ring will be compressed between the straight section 12 and the pot body to form a tight sealing interface. The straight section 12 ensures the uniform compression and distribution of the sealing ring, thereby improving the sealing effect. A flange 13 extending in a direction away from the inner cover 2 is also provided after the second oblique straight section 11, which enhances the aesthetic appearance of the pot cover and provides additional structural support and stability. In addition, in other embodiments, the flange 13 can also be used to cooperate with a locking mechanism (such as a lock) on the pot body to ensure that the pot cover is tightly fixed during the cooking process and prevent accidental opening. Figure 6 As shown, in other embodiments, the flange 13 may not be provided on the outer cover 1.

[0044] In summary, when the pot cover and the pot body are used together, the first oblique straight section 21 of the inner cover 2 and the second oblique straight section 11 of the outer cover 1 are tightly fitted to form a stable sealing surface. At the same time, the sealing ring is sleeved on the first oblique straight section 21 and is compressed between the straight section 12 and the pot body to form a continuous sealing ring, ensuring the tight connection and sealing effect between the pot cover and the pot body, and preventing the leakage of steam and food.

[0045] In other embodiments, Figure 7 and Figure 8 As shown, the end of the flange 13 away from the straight section 12 can also be configured as a curling edge 131, and the end of the curling edge 131 extends toward the straight section 12 to strengthen the strength of the flange 13 and the pot cover. In addition, a steel ring 132 can also be configured between the flange 13 and the second oblique straight section 11 to further strengthen the strength of the pot cover.

[0046] like Fig. 9 As shown, one end of the flange 13 away from the straight section 12 is configured as a curling edge 131, and the end of the curling edge 131 is welded to the outer surface of the outer cover 1. In other embodiments, the end of the curling edge 131 can also be welded to the outer surface of the outer cover 1.

[0047] The outer cover 1 is formed with an annular reinforcement rib 14 protruding in a direction away from the inner cover 2 .

[0048] In this embodiment, the annular reinforcing ribs 14 are located on the outer cover 1, specifically protruding in a direction away from the inner cover 2, and the reinforcing ribs 14 can be evenly distributed on the edge of the outer cover 1, thereby providing effective support and reinforcement. The reinforcing ribs 14 can also significantly enhance the structural strength of the outer cover 1. During the high-pressure and high-temperature cooking process, the pot cover may be subjected to various forces from the inside and outside, and the annular reinforcing ribs 14 can effectively resist these forces to prevent the pot cover from deformation or damage.

[0049] The pot cover comprises a locking tongue 5 movably arranged on the outer cover 1 , and the bottom surface of the locking tongue 5 is higher than the top surface of the outer cover 1 .

[0050] In this embodiment, the locking tongue 5 is movably arranged on the outer cover 1, and the pot body is provided with a lock buckle or a slot structure that matches the locking tongue 5. The user can flexibly operate the locking tongue 5 as needed to achieve locking or unlocking of the pot cover and the pot body. The bottom surface of the locking tongue 5 is higher than the top surface of the outer cover 1. When the locking tongue 5 matches with the corresponding structure (such as the lock buckle) on the pot body, an effective locking mechanism can be formed and the outer cover 1 will not interfere with the movement of the locking tongue 5, ensuring the convenience and safety of the user when operating the pot cover, and preventing the pot cover from being accidentally opened during cooking.

[0051] The maximum value of the outer diameter of the outer cover 1 is greater than the maximum value of the outer diameter of the inner cover 2 .

[0052] In this embodiment, the outer cover 1 and the inner cover 2 are both roughly circular, which makes the pot cover more harmonious and unified visually, and also conforms to the circular design of most pots, so that the pot cover and the pot body can be closely matched. The maximum outer diameter of the outer cover 1 is greater than the maximum outer diameter of the inner cover 2, so that the outer cover 1 can cover the outside of the inner cover 2, providing additional protection for the inner cover 2, and also increasing the overall thickness and strength of the pot cover.

[0053] The pot cover includes a functional valve 6. A first valve hole is opened on the outer cover 1, and a second valve hole corresponding to the position of the first valve hole is opened on the inner cover 2. The functional valve 6 passes through the first valve hole and the second valve hole to fix the outer cover 1 and the inner cover 2.

[0054] In this embodiment, a first valve hole is provided on the outer cover 1, and the diameter and shape of the first valve hole match the functional valve 6, so that the functional valve 6 can smoothly pass through the outer cover 1. A second valve hole corresponding to the position of the first valve hole is also provided on the inner cover 2. When the inner cover 2 is stacked on the outer cover 1, the two valve holes will be aligned with each other to ensure that the functional valve 6 can smoothly move between the double-layer pot cover. With the functional valve 6 passing through the first valve hole and the second valve hole, the outer cover 1 and the inner cover 2 are firmly fixed together, ensuring that the inner cover 2 and the outer cover will not shift or loosen during the cooking process. Specifically, the functional valve 6 can be a pressure relief valve, an exhaust valve, a check valve, etc.

[0055] The pot cover includes a fastener 7. A first mounting hole is opened on the outer cover 1, and a second mounting hole corresponding to the position of the first mounting hole is opened on the inner cover 2. The fastener 7 passes through the first mounting hole and the second mounting hole to fix the inner cover 2 and the outer cover 1.

[0056] In this embodiment, the inner cover 2 and the outer cover 1 are firmly connected by the fastener 7 passing through the mounting holes of the inner and outer covers 1, forming a stable integral structure. The introduction of the fastener 7 makes the installation and removal of the inner and outer covers 1 simple and convenient, and the user can easily perform maintenance and cleaning work. In addition, the fastener 7 can adapt to pot covers of different sizes and shapes, and only the position and number of the mounting holes need to be adjusted. Specifically, the fastener 7 includes bolts, screws, etc. The fastener 7 passes through the first mounting hole of the outer cover 1 and the second mounting hole of the inner cover 2 to fix the inner cover 2 and the outer cover 1. During the installation process, one end of the fastener 7 (usually the threaded part) will be fixed on a layer between the inner and outer covers 1 (for example, through a nut or a threaded hole on the inner cover 2), while the other end passes through the double-layer pot cover and may be exposed outside the outer cover 1, which is convenient for the user to tighten or loosen the operation.

[0057] In this embodiment, the pot cover is provided with both fasteners 7 and functional valves 6. In other embodiments, the pot cover may be provided with only fasteners 7 or functional valves 6, as long as they can connect the outer cover 1 and the inner cover 2, which is not limited here.

[0058] like Figure 5 As shown, in this embodiment, a protrusion 22 protruding toward the outer cover 1 is formed on the inner cover 2, and a groove 15 recessed in a direction away from the inner cover 2 is formed on the outer cover 1. The protrusion 22 cooperates with the groove 15 to fix the inner cover and the outer cover so that the inner cover and the outer cover will not slide relative to each other easily.

[0059] In this embodiment, a stopper 23 is formed on the inner cover 2 , and the stopper 23 is arranged at the end of the first oblique straight section 21 . The lower end of the seal 3 abuts against the stopper 23 to prevent the seal 3 from falling off.

[0060] This embodiment also provides a pressure cooker, comprising a cooker body and a cooker cover, wherein the cooker cover comprises the aforementioned cooker cover.

[0061] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
