[0026] 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.

[0027] 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.

[0028] Example:

[0029] like Figures 1 to 3 As shown, this embodiment provides a pressure cooker, comprising a pot body 1 and a pot cover 2, wherein the pot cover 2 is formed with a flange 21 extending toward the inside of the pot body 1 on one side facing the pot body 1; the pot body 1 is provided with a rim 11 on one side close to the pot cover 2, the top end of the rim 11 is bent along a horizontal direction toward the inside of the pot body 1 to form a locking groove 112, and the pot cover 2 comprises a locking tongue 24, which at least partially extends into the locking groove 112 to lock the pot cover 2 on the pot body 1.

[0030] In a conventional pressure cooker, the sealing structure between the pot cover 2 and the pot body 1 is usually relatively simple, and mainly relies on the direct contact between the sealing ring 23 and the mouth of the pot body 1 to achieve sealing. However, due to the aging and wear of the sealing ring 23 material, and the slight change in the shape of the mouth of the pot body 1, the sealing performance may be reduced. In addition, the conventional pot cover 2 design often lacks effective fixation and support for the sealing ring 23, so that the sealing ring 23 is easily deformed when subjected to pressure, further reducing the sealing effect. Therefore, a pressure cooker is provided in this embodiment, and the pot body 1 is the main part of the pressure cooker, and its shape and size can be customized according to specific needs. The pot body 1 is usually made of a high temperature resistant and high pressure resistant metal material to ensure safety during high pressure cooking. In this embodiment, the top of the pot body 1 has a rim 11, which is annular and arranged around the opening of the pot body 1. The pot cover 2 is a component covering the top of the rim 11 of the pot body 1, and is used to close the opening of the pot body 1. In addition, the pot cover 2 is formed with a flange 21 extending toward the inside of the pot body 1 on the side facing the pot body 1. In this embodiment, the flange 21 is integrally formed with the main body of the pot cover 2 and extends around the central axis of the pot cover 2. The shape and size of the flange 21 match the rim 11 of the pot body 1 to ensure a close fit between the two. The top of the rim 11 is bent toward the inside of the pot body 1 to form a locking groove 112, so that the pot cover 2 and the pot body 1 can form a closer contact when closed, ensuring that the gap between the pot cover 2 and the pot body 1 is minimized, thereby reducing the overflow of steam or food soup and enhancing the sealing performance of the pot. The bent rim 11 can prevent food residues or soup from accumulating between the pot body 1 and the pot cover 2, making the cleaning process simpler and more convenient. The locking tongue 24 can enter the locking groove 112 to lock the pot cover on the pot body, that is, the flange 21 can resist the locking tongue 24 to achieve the fixation of the locking tongue 24 and the pot cover 2, and the pressure cooker can maintain a high degree of sealing during the cooking process, thereby maintaining the pressure and temperature during the cooking process and achieving a better cooking effect.

[0031] A reinforcing rib 22 is provided on the side of the pot cover 2 facing away from the pot body 1. The reinforcing rib 22 is constructed in an annular shape and has a clearance groove 221. The pot cover 2 includes a driving mechanism 25. The rim 11 is provided with a locking groove 112 engaged with the locking tongue 24. The driving mechanism 25 drives the locking tongue 24 to pass through the clearance groove 221 and disengage from or engage with the locking groove 112.

[0032] In this embodiment, the reinforcing ribs 22 and the flanges 21 are arranged on both sides of the pot cover 2. The design of the reinforcing ribs 22 can significantly improve the structural strength of the pot cover 2, making it more durable. During high-pressure cooking, the pot cover 2 needs to withstand strong pressure from the inside of the pot body 1. The reinforcing ribs 22 can effectively disperse this pressure and prevent the pot cover 2 from causing safety accidents due to deformation or rupture. Figure 5As shown, in this embodiment, the annular reinforcing rib 22 can significantly improve the structural strength of the pot cover 2, enhance its pressure resistance under high pressure environment, and prevent safety hazards caused by deformation or rupture. The clearance groove 221 provided on the reinforcing rib 22 provides enough space for the lock tongue 24, so that it can pass smoothly and achieve engagement or disengagement with the locking groove 112 of the pot body 1. The clearance groove 221 optimizes the structure of the pot cover 2, making it more compact and reasonable, while not affecting the overall strength and aesthetics of the pot cover 2. The lock tongue 24 cooperates with the locking groove 112 of the rim 11 of the pot body 1, and is engaged or disengaged through the drive of the driving mechanism 25, ensuring the tight locking between the pot cover 2 and the pot body 1, and preventing accidental opening of the lid during cooking. The driving mechanism 25 allows the user to easily control the action of the lock tongue 24, thereby quickly completing the locking or unlocking operation of the pot cover 2.

[0033] The driving mechanism 25 includes a first driving member 251 and a second driving member 252 fixedly connected to the lock tongue 24. The first driving member 251 is constructed as a turntable. The second driving member 252 is provided with a guide column. The first driving member 251 is provided with an arc guide groove corresponding to the guide column one by one. When the first driving member 251 rotates, the guide groove drives the guide column to move in the guide groove to move the lock tongue 24.

[0034] like Figure 4 As shown, in this embodiment, the movement of the locking tongue 24 can be accurately controlled by rotating the first driving member 251 (turntable). The design of the arc-shaped guide groove makes the moving track of the guide column therein match the moving path of the locking tongue 24, thereby achieving accurate engagement or disengagement between the locking tongue 24 and the locking groove 112. The user only needs to simply rotate to achieve locking or unlocking of the pot cover 2. Through the cooperation of the guide groove and the guide column, the first driving member 251 can drive the locking tongue 24 to translate when rotating, thereby achieving separation or engagement of the pot body 1 and the pot cover 2.

[0035] There are two locking tongues 24 , and the reinforcing rib 22 is provided with two paving grooves 221 corresponding to the positions of the locking tongues 24 .

[0036] In this embodiment, the two locking tongues 24 are respectively located at different positions of the pot cover 2. When they are engaged with the locking groove 112 of the pot body 1 at the same time, the pot cover 2 can be evenly stressed on the pot body 1, avoiding deformation or damage of the pot cover 2 due to uneven local stress. The two giving way grooves 221 provided on the reinforcing rib 22 correspond to the positions of the locking tongues 24 one by one, ensuring that the locking tongues 24 can pass smoothly during the movement without being hindered, improving the smoothness of the operation, and also enhancing the stability and reliability of the entire driving mechanism 25. In other embodiments, the locking tongues 24 can also be configured as multiple, and the design of multiple locking tongues 24 makes the pressure cooker suitable for pot bodies 1 of different sizes and specifications. By adjusting the distance and position between the locking tongues 24, it can be easily matched with the locking grooves 112 on different pot bodies 1, improving the versatility and adaptability of the product.

[0037] A sealing ring 23 is disposed between the rim portion 11 and the flange 21 ; along the extending direction of the flange 21 , the distance between the rim portion 11 and the flange 21 is continuously reduced to compress the sealing ring 23 .

[0038] A sealing ring 23 is arranged between the rim 11 and the flange 21 of the pot cover 2. The sealing ring 23 is usually made of a soft, high temperature resistant, high pressure resistant material, such as silicone or rubber, and the sealing ring 23 is used to fill the gap between the two to achieve a tight sealing effect. In addition, the spacing between the rim 11 and the flange 21 along the extension direction of the flange 21 is continuously reduced, so that the contact between the sealing ring 23 and the rim 11 is closer, forming an effective seal, so that the pressure cooker can maintain a high sealing performance during the cooking process, thereby maintaining the pressure and temperature during the cooking process, and achieving a better cooking effect. There are many ways to continuously reduce the spacing between the rim 11 and the flange 21. For example, an inclined surface or a curved surface can be set on the inner side of the flange 21 and / or the outer side of the rim 11, so that the spacing between the rim 11 and the flange 21 is gradually reduced, thereby pressing the sealing ring 23 to achieve a tighter seal.

[0039] The sealing ring 23 has two side walls, one of which is fixedly connected to the flange 21 , and the other side wall is in contact with the rim 11 .

[0040] The two side walls of the sealing ring 23 are in close contact with the flange 21 and the rim 11 respectively, forming a complete sealing surface, thereby effectively preventing the leakage of steam, liquid or food, ensuring the sealing between the pot cover 2 and the pot body 1, and enabling the pressure cooker to work safely and stably under high pressure or high temperature conditions.

[0041] The rim 11 is formed with a first oblique straight section 111 inclined toward the flange 21 along the extending direction of the flange 21 , and the flange 21 is formed with a second oblique straight section 211 inclined toward the rim 11 along the extending direction of the flange 21 .

[0042] like Figure 3 and Figure 6 As shown, in the present embodiment, since both the rim 11 and the flange 21 are designed with oblique straight sections inclined toward each other, when the pot cover 2 is closed on the pot body 1, the first oblique straight section 111 and the second oblique straight section 211 will approach each other, thereby more effectively compressing the sealing ring 23, ensuring that when high pressure is formed inside the pot body 1, the sealing ring 23 will not be pushed open by the pressure, but will be pressed more tightly between the rim 11 and the flange 21, thereby achieving a better sealing effect.

[0043] The flange 21 is configured as a ring or a plurality of arc segments evenly distributed on the pot cover 2 .

[0044] In this embodiment, the flange 21 is configured as a ring, ensuring that the sealing ring 23 can be subjected to uniform sealing pressure when the pot cover 2 is closed with the pot body 1, which helps prevent damage or leakage of the sealing ring 23 due to excessive local pressure during high-pressure cooking, thereby improving the sealing effect and cooking safety. In other embodiments, the flange 21 can also be configured as a plurality of arc segments evenly distributed on the pot cover 2.

[0045] The diameter of the flange 21 gradually increases in the direction away from the pot body 1 .

[0046] In this embodiment, the diameter of the flange 21 gradually increases in the direction away from the pot body 1 , and the locking tongue 24 cooperates with the flange 21 .

[0047] The diameter of the flange 21 gradually decreases in the direction away from the pot body 1 .

[0048] In other embodiments, the diameter of the flange 21 may also gradually decrease in the direction away from the pot body 1, so as to further enhance the sealing effect of the pressure cooker.

[0049] The reinforcing rib 22 is formed with a straight section 222 that abuts against the sealing ring 23. The straight section 222 of the reinforcing rib 22 is in direct contact with the sealing ring 23, providing a stable support surface for the sealing ring 23, which helps to ensure that the sealing ring 23 can fit more closely when the pot cover 2 and the pot body 1 are closed, thereby effectively preventing the gas and moisture inside the pressure cooker from leaking out and improving the sealing effect.

[0050] 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. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
