Description

Technical Field

[0001] This utility model relates to a cooking utensil, and more particularly to a sealing ring and a cooking pot using the same. Background Technology

[0002] A high-quality sealing ring effectively prevents steam and heat from escaping, allowing a high-temperature, high-pressure environment to form inside the pot more quickly. For example, pressure cookers rely on the sealing ring to increase internal pressure, raising the boiling point of water above 100°C and significantly shortening cooking time. A well-sealed lid reduces internal heat convection disturbances, preventing localized heat loss and ensuring more even heating of food, thereby improving heating efficiency.

[0003] However, the sealing ring is usually fixed on the pot lid. To ensure the sealing effect of the sealing ring, it is necessary not only to ensure the sealing effect between the sealing ring and the pot body, but also to ensure the sealing effect between the pot lid and the sealing ring.

[0004] Traditional sealing rings have the following technical problems:

[0005] First, the tilted lid causes seal failure: In existing technology, the lid is often tilted when closed, which can easily create gaps between the sealing ring and the lid, compromising the seal. These gaps allow steam to leak out, reducing the pressure inside the pot and affecting cooking performance.

[0006] Secondly, the limitations of static sealing: Traditional sealing rings mostly rely on static structures (such as fixed protrusions or pressing surfaces) to achieve sealing, and cannot dynamically adapt to the tilt or deformation of the pot lid. Especially under high temperature and high pressure environments, the sealing ring is prone to losing its sealing performance due to elastic fatigue.

[0007] Third, insufficient utilization of hot steam: Existing technology fails to fully utilize the pressure dynamics of hot steam inside the boiler to enhance the sealing effect, which may cause the sealing ring to loosen or deform under high temperature conditions, further aggravating the leakage problem. Utility Model Content

[0008] This utility model designs a sealing ring and a cooking pot using it. The technical problem it solves is that the existing pot lid has a certain degree of tilt, and when the pot lid and the sealing ring are combined, gaps that damage the seal are easy to appear. This technical problem needs to be solved.

[0009] To solve the aforementioned technical problems, the present invention adopts the following solution:

[0010] A sealing ring includes a first sealing ring and a second sealing ring, which are connected to form an integral part. The first sealing ring is connected to a pot lid, and the second sealing ring is connected to a sealing surface of the pot body. The first sealing ring has a pot lid mounting cavity, and an insertion port communicates with the mounting cavity. The characteristic feature is that a pot lid sealing protrusion is provided at the lower end of the insertion port, and the pot lid sealing protrusion can seal the tilted pot lid through the hot steam in the pot body.

[0011] Preferably, the first sealing ring includes an upper sealing part and a lower sealing part, the common side of the upper sealing part and the lower sealing part is connected by a connecting part, the common other side of the upper sealing part and the lower sealing part is an insertion port, and the lid sealing protrusion is provided on the lower sealing part.

[0012] Preferably, when the pot lid is inserted into the mounting cavity, there is a gap between the pot lid sealing protrusion, the lower sealing part, and the pot lid.

[0013] Preferably, when the lid is inserted into the mounting cavity, the lid sealing protrusion is sloped and fits against the bottom surface of the lid, and there are no gaps between the lid sealing protrusion, the lower sealing part, and the lid.

[0014] Preferably, the second sealing ring includes a first sealing ring piece and a second sealing ring piece, the first sealing ring piece and the second sealing ring piece are connected to form a first included angle, and the first sealing ring piece is connected to the lower sealing part to form a second included angle.

[0015] Preferably, the connection point between the first sealing ring and the lower sealing part is located below the sealing protrusion of the pot lid, and the length of the first sealing ring is greater than the length of the second sealing ring, so that the upward hot steam inside the pot can act on the sealing protrusion of the pot lid to make it adhere to the pot lid. Alternatively, the length of the first sealing ring is not greater than the length of the second sealing ring.

[0016] Preferably, the first included angle is greater than the second included angle to prevent the first and second sealing rings from easily losing their elasticity. Alternatively, the first included angle is not greater than the second included angle; the first included angle and the second included angle face opposite directions, and the opening of the first included angle faces the center of the sealing ring.

[0017] Preferably, there are multiple second sealing rings, each of which includes a first sealing ring piece and a second sealing ring piece, and the multiple second sealing rings are connected to form a continuous "V" or "U" shape.

[0018] Preferably, the pot body has an arc-shaped sealing surface that fits against the second sealing ring or a combination of a horizontal sealing surface and a vertical sealing surface.

[0019] A cooking pot, characterized in that it includes the aforementioned sealing ring, lid, and pot body.

[0020] The sealing ring and the cooking pot using it have the following beneficial effects:

[0021] (1) This utility model uses the design of the lid sealing protrusion to automatically fit the inclined surface of the lid when it is closed, effectively eliminating the gap problem caused by the angle deviation of the lid in traditional sealing rings.

[0022] (2) This utility model achieves double sealing protection and has excellent anti-leakage performance. In the initial mechanical seal, when the pot lid is inserted into the installation cavity, the sealing protrusion of the pot lid and the pot lid form a basic seal. Steam-assisted sealing: When the pressure inside the pot increases, the steam pushes the first sealing ring to deform, so that the sealing protrusion presses more tightly against the pot lid, completely eliminating leakage.

[0023] (3) This utility model not only achieves a seal between the pot lid and the sealing ring, but also the double-ring plate structure of the second sealing ring can adapt to the sealing surface of the pot body, ensuring that the sealing ring is fully sealed to both the pot lid and the pot body.

[0024] (4) The present invention adopts a structural design in which the first included angle is greater than the second included angle, so that the sealing ring can still maintain elasticity under steam pressure and avoid deformation and failure due to long-term high temperature and high pressure.

Detailed Implementation

[0034] The following is combined with Figures 1 to 7 The present invention will be further described below:

[0035] like Figure 1 As shown, the sealing ring of this utility model includes a first sealing ring 1 and a second sealing ring 2.

[0036] The first sealing ring 1 is used to connect with the pot lid 3, and includes an upper sealing part 12 and a lower sealing part 16, which are connected as one unit by a connecting part 17 to form a mounting cavity 13 for accommodating the edge of the pot lid. An insertion port 18 is located on one side of the mounting cavity 13 for inserting the edge of the pot lid 3. A pot lid sealing protrusion 11 is provided on the lower sealing part 16 to enhance the sealing effect when the pot lid is closed.

[0037] The second sealing ring 2 is used to connect with the sealing surface 41 of the pot body 4. It includes a first sealing ring piece 21 and a second sealing ring piece 22, which form a first included angle 23 to enhance the elastic sealing ability. The first sealing ring piece 21 is connected to the lower sealing part 16 to form a second included angle 24, so that the sealing ring can better fit the pot body.

[0038] The connection point between the first sealing ring 21 and the lower sealing part 16 is located below the sealing protrusion 11 of the pot lid. The length of the first sealing ring 21 is greater than the length of the second sealing ring 22, so that the upward hot steam inside the pot body 4 can act on the sealing protrusion 11 of the pot lid to make it adhere to the pot lid 3. Of course, the length of the first sealing ring 21 can also be no greater than the length of the second sealing ring 22, but the effect will not be as good as the former.

[0039] The first included angle 23 being greater than the second included angle 24 prevents the first sealing ring 1 and the second sealing ring 2 from easily losing their elasticity. The sealing rings maintain their elasticity under pressure, preventing them from losing their sealing performance due to long-term use. Of course, the first included angle 23 can also be no greater than the second included angle 24, but the effect will be less than the former.

[0040] The first included angle 23 and the second included angle 24 face opposite directions, with the opening of the first included angle 23 facing the center of the sealing ring.

[0041] The pot body 4 has an arc-shaped sealing surface or a combination of a horizontal sealing surface and a vertical sealing surface that fits with the second sealing ring 2. The second sealing ring 2 can self-adjust to ensure a complete seal.

[0042] like Figure 2 As shown, the sealing ring of this utility model is annular, and the annular upper sealing part 12 can be seen from the front of the pot lid facing downwards.

[0043] like Figure 3 As shown, the sealing ring of this utility model is annular. From the back of the pot lid, the first sealing ring 21 and the second sealing ring 22 are visible. A portion of the first sealing ring 21 is blocked by the second sealing ring 22.

[0044] like Figure 4 As shown, the initial state when the lid is closed: After the edge of the lid 3 is inserted into the mounting cavity 13, the lid sealing protrusion 11 fits against the bottom surface of the lid, ensuring an initial seal. At this time, there is a gap 14 between the lid sealing protrusion 11, the lower sealing part 16 and the lid 3.

[0045] like Figure 5 As shown, the lid sealing protrusion 11 can also be a second shape: the lid sealing protrusion 11 is an entire slope 15. The slope 15 fits completely against the bottom surface of the lid 3, and there are no gaps between the lid sealing protrusion 11, the lower sealing part 16, and the lid 3.

[0046] like Figure 6 As shown, the dynamic seal under the action of hot steam is as follows:

[0047] When hot steam is generated inside the pot, the steam pressure pushes the first sealing ring 1 to deform upward, so that the sealing protrusion 11 of the pot lid fits the pot lid 3 more tightly, eliminating any possible gaps between the first sealing ring 1 and the pot lid 3.

[0048] At the same time, when hot steam is generated inside the pot, the steam pressure pushes the second sealing ring 2 to deform toward the sealing surface 41 of the pot body 4, and makes the included angle formed by the first sealing ring piece 21 and the second sealing ring piece 22 fit onto the sealing surface 41 of the pot body 4, preventing hot steam from escaping between the pot body and the sealing ring.

[0049] Therefore, the sealing ring achieves a seal between itself and the pot lid 3 through the first sealing ring 1, and a seal between itself and the pot body 4 through the second sealing ring 2.

[0050] like Figure 7 As shown, the sealing ring of this utility model can also be a plurality of second sealing rings 2, each of which includes a first sealing ring piece 21 and a second sealing ring piece 22, and the plurality of second sealing rings 2 are connected to form a plurality of continuous “V” or “U” shapes. Figure 2 There are two second sealing rings.

[0051] This utility model of a cooking pot includes a sealing ring, a lid 3, and a pot body 4, as described above. Cooking pots include, but are not limited to, metal pots, non-metal pots, titanium pots, frying pans, stew pots, soup pots, milk pots, hot pots, electric hot pots, electric frying pans, pressure cookers, rice cookers, purple clay pots, earthenware pots, wooden fish stone pots, maifan stone pots, health-preserving pots, etc.

[0052] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
