[0002] Pressure cookers, as kitchen appliances capable of quickly cooking food, have been widely accepted by consumers. Pressure cookers utilize the high pressure and high temperature environment generated inside a sealed pot to achieve ideal cooking results in a short time, saving time while preserving the food's nutrition and taste. Chinese Patent No. CN202421473123.2 discloses a pot lid and pressure cooker, relating to the field of cooking utensils. It includes a sealing element, an outer lid, and an inner lid stacked and fixed to the outer lid. The edge of the inner lid extends away from the outer lid to form an installation space between the edge of the outer lid and the edge of the inner lid. The sealing element is installed within this installation space. This utility model has the advantages of easy sealing and a high-strength lid.

[0003] Based on the above, the inventors have discovered the following problems: While the aforementioned device has the advantages of high sealing and lid strength, it overlooks the complex structure of the pressure cooker. The lid has numerous components, and with prolonged use, these components easily accumulate debris, especially food residue. If this residue is not cleaned promptly and thoroughly, it can easily breed bacteria, contaminating the food inside the pot and posing a threat to food safety. Furthermore, the numerous components also make maintenance cumbersome, increasing the operational difficulty and skill level for maintenance personnel, extending maintenance time, and increasing maintenance costs. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a detachable, leak-proof, sealed pressure cooker, comprising a pot body and a rotating component. The upper end of the pot body is provided with a pot lid, and the lower end of the pot lid is provided with a plurality of fixing components arranged in a circular array. A connecting ring is provided on the side of the pot body, and a connecting component is connected to the connecting ring. A sliding ring is provided on the outer side of the connecting component. A sliding groove is provided on the inner side of the rotating component, and the sliding ring slidably engages with the sliding groove. A plurality of through holes are arranged in a circular array on the connecting ring, and a plurality of fixing holes are arranged in a circular array on the rotating component. The fixing components, through holes, and fixing holes have the same cross-sectional dimensions. A recessed hole is provided on the fixing component, allowing the fixing component to pass through the through hole and the fixing hole sequentially. When the fixing component passes through, the inner wall structure of the fixing hole engages with the recessed hole. A connecting assembly is provided between the connecting component and the pot body. A sealing assembly is provided between the upper end of the pot body and the bottom end of the pot lid.

[0005] Furthermore, the connecting assembly includes a threaded strip located on the outer wall of the pot body and a threaded groove provided on the inner wall of the connector, wherein the threaded groove is threadedly connected to the threaded strip.

[0006] Furthermore, the sealing assembly includes a groove formed on the upper end of the side wall of the pot body, and a sealing ring is movably disposed in the groove.

[0007] Furthermore, a sealing ring is provided at the bottom of the pot lid, the outer diameter of the sealing ring is less than or equal to the inner diameter of the pot body, and a limiting groove is provided on the outer side of the sealing ring and at the bottom of the pot lid, the width of the limiting groove being the same as the thickness of the upper side wall of the pot body.

[0008] Furthermore, the height from the top of the fastener to the bottom of the recess is equal to the height from the top of the through hole to the bottom of the fixing hole.

[0009] Furthermore, a rotating rod is provided on the outer side of the rotating component, and the outer surface of the rotating rod is covered with an anti-scalding layer.

[0010] Furthermore, a pair of handles are symmetrically fixed to the side wall of the pot body, and a handle is provided at the upper end of the pot lid.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this detachable leak-proof sealed pressure cooker is reasonable and has the following advantages:

[0012] (1) Traditional pressure cookers are prone to accumulating food residue and grease around their moving parts and in the gaps between the parts and the pot body. These areas are usually complex in structure and narrow in space, making them difficult to reach with conventional cleaning tools, thus becoming a breeding ground for stubborn stains and bacteria. Moreover, maintenance often requires complete replacement or complex disassembly. This device achieves threaded connection between the connector and the pot body through the threaded strip and threaded groove, making the connector, slip ring, rotating parts and their fixing holes and rotating rods as a whole module, which can be easily unscrewed and removed from the pot body. Users can directly scrub and rinse these parts thoroughly to ensure the removal of all food residue and grease, eliminating hygiene hazards. Furthermore, when a part of this device malfunctions, thanks to the modular design, the entire module can be removed without professional tools or complex operations. Users can easily check the problem and replace the damaged individual parts or the entire module, which greatly reduces the technical threshold, time and cost of maintenance.

[0013] (2) By combining the sealing ring and the sealing ring, a two-stage sealing effect is achieved; so that if one of the seals has a small leakage path due to minor defects, aging or instantaneous pressure impact, the other seal can still effectively prevent steam from overflowing, greatly reducing the overall leakage probability; this design not only provides a reliability far exceeding that of a single seal, effectively preventing high-pressure steam leakage and ensuring cooking safety and efficiency; its pressure adaptability, structural stability and easy maintenance features together ensure the stability and durability of the sealing performance during long-term use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example:

[0023] In this embodiment, a detachable leak-proof sealing pressure cooker includes a pot body 1 and a rotating component 18. The upper end of the pot body 1 is provided with a pot lid 2, and the lower end of the pot lid 2 is provided with a plurality of fixing components 6 arranged in a circular array. A connecting ring 12 is provided on the side of the pot body 1, and the connecting ring 12 is connected to a connecting component 16. A sliding ring 17 is provided on the outer side of the connecting component 16. A sliding groove 20 is provided on the inner side of the rotating component 18, and the sliding ring 17 slidably fits into the sliding groove 20. A plurality of through-holes are arranged in a circular array on the connecting ring 12. The rotating component 18 has a plurality of fixing holes 19 arranged in a ring array. The fixing component 6, the through hole 15, and the fixing holes 19 have the same cross-sectional dimensions. The fixing component 6 has a recessed hole 11, through which the fixing component 6 can pass in sequence through the through hole 15 and the fixing hole 19. When the fixing component 6 passes through, the inner wall structure of the fixing hole 19 engages with the recessed hole 11. A connecting component is provided between the connecting component 16 and the pot body 1. A sealing component is provided between the upper end of the pot body 1 and the bottom end of the pot lid 2.

[0024] When using this device for cooking, the operator rotates the rotating rod 4 to make the rotating part 18 rotate on the connecting part 16, thereby aligning the fixing hole 19 on the rotating part 18 with the through hole 15 on the connecting ring 12. Then, the fixing parts 6 on the pot lid 2 are aligned with the through hole 15, and the pot lid 2 and the pot body 1 are combined together. Then, the rotating rod 4 is rotated to make the rotating part 18 rotate, so that the side wall of the fixing hole 19 on the rotating part 18 is inserted into the recessed hole 11 on the fixing part 6, thereby firmly fixing the pot body 1 and the pot lid 2, and then the cooking process can be carried out.

[0025] The connecting component includes a threaded strip 14 on the outer wall of the pot body 1 and a threaded groove 13 on the inner wall of the connector 16, wherein the threaded groove 13 is threadedly connected to the threaded strip 14.

[0026] The design of the threaded connection between the connector 16 and the pot body 1 allows for easy and convenient disassembly of the connector 16 and its components, thereby facilitating maintenance and cleaning, reducing maintenance difficulty, and improving the hygiene and safety of the cooking container.

[0027] The sealing assembly includes a slot 8 formed on the upper side wall of the pot body 1, and a sealing ring 7 is movably disposed in the slot 8.

[0028] With the design of the slot 8 and the sealing ring 7, the sealing ring 7 is used to seal the gap between the pot body 1 and the pot lid 2. The slot 8 can limit the sealing ring 7, and the sealing ring 7 can be easily removed within the slot 8, thus facilitating the user's cleaning operation.

[0029] The bottom of the pot lid 2 is provided with a sealing ring 9. The outer diameter of the sealing ring 9 is less than or equal to the inner diameter of the pot body 1. A limiting groove 10 is provided on the outer side of the sealing ring 9 and at the bottom of the pot lid 2. The width of the limiting groove 10 is the same as the thickness of the upper side wall of the pot body 1.

[0030] The outer diameter of the sealing ring 9 is slightly less than or equal to the inner diameter of the pot body 1;

[0031] As the sealing ring 7 inside the slot 8 is inserted into the limiting groove 10 at the edge of the pot body, it is squeezed between the outer surface of the side wall of the pot body 1 and the groove wall of the limiting groove 10, forming the first annular sealing barrier. The protruding sealing ring 9 fits tightly against the inner wall of the pot body 1, forming the second annular sealing barrier. When the rotating rod 4 is rotated to drive the rotating part 18 to rotate, causing the side wall of the fixing hole 19 to engage with the concave hole 11 of the fixing part 6, the pot lid 2 is pulled down forcefully. This action simultaneously strengthens the double seal: the sealing ring 7 inside the limiting groove 10 is further compressed to ensure a tight seal; at the same time, the sealing ring 9 fits more tightly against the inner wall of the pot body 1.

[0032] The design incorporates two independent physical sealing barriers: a dual-layer design with a compression seal by the sealing ring 7 and a close-fitting seal by the sealing ring 9. Even if one of the seals experiences a minor leak due to slight defects, aging, or instantaneous pressure shocks, the other seal can still effectively prevent steam from escaping, significantly reducing the overall probability of leakage. When the pressure inside the pot body 1 increases, the pressure acting on the lid 2 forces the sealing ring 9 to press more tightly against the inner wall of the pot body 1, enhancing the second-level seal. At the same time, it also presses the lid 2 more tightly against the edge of the pot body 1, further compressing the sealing ring 7 within the limiting groove 10 to enhance the first-level seal. This design allows the sealing effect to automatically increase with rising pressure. The structure of the limiting groove 10 precisely accommodates the edge of the pot body, and the design of the fastener 6 being ultimately locked in place not only provides a strong locking force but also ensures the precise alignment of the lid 2 and the pot body 1 under high pressure, preventing damage to the sealing surface due to misalignment or warping.

[0033] The height from the top of the fastener 6 to the bottom of the recessed hole 11 is equal to the height from the top of the through hole 15 to the bottom of the fixing hole 19.

[0034] The rotating component 18 is provided with a rotating rod 4 on its outer side, and the outer surface of the rotating rod 4 is covered with an anti-scalding layer.

[0035] With the design of the rotating rod 4, the rotating part 18 can be easily rotated on the connecting part 16 by rotating the rotating rod 4. The rotating rod 4 is also designed with an anti-scalding layer to avoid the risk of users being burned.

[0036] The pot body 1 has a pair of handles 5 symmetrically fixedly connected to its side wall, and the pot lid 2 has a handle 3 at its upper end.

[0037] The pot body 1 and pot lid 2 can be easily held by a pair of handles 5 and handles 3.

[0038] Working principle: When using this device for cooking, the operator rotates the rotating rod 4, causing the rotating part 18 to rotate on the connecting part 16. This aligns the fixing hole 19 on the rotating part 18 with the through hole 15 on the connecting ring 12. Then, several fixing parts 6 on the lid 2 are aligned with the through hole 15, thus combining the lid 2 and the pot body 1. The sealing ring 7 is located in the slot 8, and the sealing ring 9 is locked inside the pot body 1. The side wall of the pot body 1 and the sealing ring 7 are located in the limiting groove 10, thereby sealing the gap between the lid 2 and the pot body 1. Then, rotating the rotating rod 4 again causes the rotating part 18 to rotate, causing the side wall of the fixing hole 19 on the rotating part 18 to engage with the recess 11 on the fixing part 6, thus firmly fixing the pot body 1 and the lid 2 together. The cooking process can then begin. The threaded connection between the connecting part 16 and the pot body 1 allows the connecting part 16 and its components to be disassembled from the pot body 1, facilitating thorough cleaning of the entire device and ensuring the hygiene and safety of the cooking container.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
