Technical Field
[0001] This utility model relates to a kitchen device, and more particularly to a steam-free sealing pot ring that prevents steam from overflowing from a large pot into the kitchen space. Background Technology
[0002] A steam-free sealing pot ring is a device used to prevent steam from escaping from a large pot into the kitchen through the gap between the lid and the pot rim. In use, the steam-free sealing pot ring is fixed to the edge of the pot. The lower edge of the steam-free sealing pot ring is sealed to the pot rim with a sealing ring. The upper edge of the steam-free sealing pot ring has a water seal groove, into which the edge of the pot lid is inserted to form a water seal. A steam vent is located on the side wall of the steam-free sealing pot ring, and a steam vent box or steam vent adapter is installed at the vent. This allows steam from the pot to enter the steam vent pipe through the vent or steam vent adapter, and ultimately be guided to the outside or into the stove for discharge. CN214466061 U discloses a steam-free boiler sealing structure, including a hollow vent box and a sealing profile plate inserted therein. The vent box has first notches at both ends for inserting the ends of the sealing profile plate, forming a closed ring. The insertion positions of the vent box and the sealing profile plate have corresponding first mounting holes for fasteners. The upper end of the sealing profile plate has a first sealing groove, and the upper end of the vent box has a corresponding first groove. The lower end of the sealing profile plate has a second sealing groove, and the lower end of the vent box has a corresponding second groove. A sealing strip is also provided in the second sealing groove. This allows for rapid assembly through the insertion of the sealing profile plate and the vent box, eliminating the need for pins or rubber gaskets, facilitating production, installation, and transportation, and improving assembly efficiency. Furthermore, since the vent box is part of the sealing structure, there is no need to fabricate an exhaust device structure on the sealing profile plate, reducing the height of the sealing profile plate, resulting in a compact and practical structure. However, to ensure a proper seal between the vent box and the profile plate, this steam-free boiler sealing structure requires assembly of the vent box and profile plate in the factory. The assembled vent box protrudes from the outer surface of the annular boiler ring, making it difficult to stack during transportation. Furthermore, the vent box is easily deformed and damaged by compression and impacts during transport, which can also disrupt the seal between the vent box and the profile plate, affecting the product's performance. In addition, the vent box structure is overly complex, making demolding difficult when using casting processes, resulting in low production efficiency, low yield, and high manufacturing costs. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a steam-free sealing pot ring that is convenient to transport, does not damage the airtightness of the product during transportation, and is easy to manufacture and process with low manufacturing cost.
[0004] The technical solution adopted to solve the technical problem is as follows: A steam-free sealing pot ring, comprising a circular pot ring with an upper edge that is water-sealed with the edge of the pot lid and a lower edge that is sealed with the edge of the pot by a rubber ring. A pot lid water-sealing annular groove is provided on the upper edge of the circular pot ring, and a pot edge sealing annular groove is provided on the lower edge of the circular pot ring. A sealing rubber ring is embedded in the pot edge sealing annular groove. The circular pot ring consists of a profile bending body and an arc-shaped connector that is inserted into both ends of the profile bending body. Connecting slots corresponding to the cross-sectional shape of the profile bending body are provided at both ends of the arc-shaped connector. Both ends of the profile bending body are respectively inserted into the connecting slots of the arc-shaped connector. A radial steam venting flat hole is opened on the arc-shaped connector. A steam venting adapter is installed on the outer arc surface of the arc-shaped connector corresponding to the radial steam venting flat hole. A steam venting pipe is connected to the steam venting adapter. The steam venting adapter is fixed to the arc-shaped connector by bolts, screws, or rivets.
[0005] As a further improvement of this utility model: the two ends of the profile bending body are fixed in the connecting slot of the arc-shaped connector by bolts, screws or rivets.
[0006] As a further improvement of this utility model, a silicone sealing gasket is provided between the arc-shaped connector and the exhaust adapter.
[0007] As a further improvement of this utility model, the thickness of the silicone sealing gasket is not less than 5 mm.
[0008] As a further improvement of this utility model: the silicone sealing gasket is a double-arc surface unequal thickness silicone sealing gasket.
[0009] As a further improvement of this utility model: the connecting end faces at both ends of the profile bending body are parallel to each other, and the two sealing end faces in the connecting slot that cooperate with the connecting end faces of the profile bending body are parallel to each other.
[0010] As a further improvement of this utility model: the connecting end faces at both ends of the profile bending body and the sealing end faces at both ends of the connecting slot are all on a plane determined by the radius of the circular pot ring and the central axis.
[0011] As a further improvement of this utility model: a sealing gasket or sealant is provided between the connecting end face of the profile bending body and the sealing end face of the connecting slot.
[0012] As a further improvement of this utility model: multiple fixing clips are provided on the outer arc surface of the profile bending body to cooperate with the edge of the pot and fix the circular pot ring to the edge of the pot. The fixing clips are connected to the profile bending body by bolts or screws.
[0013] Beneficial Effects: The steam-free sealing pot ring of this utility model comprises a circular pot ring with an upper edge that is water-sealed to the edge of the pot lid and a lower edge that is sealed to the pot edge by a rubber ring. The upper edge of the circular pot ring has a water-sealing groove for the pot lid, and the lower edge has a sealing groove for the pot edge. A sealing rubber ring is embedded in the sealing groove for the pot edge. The circular pot ring consists of a bent profile and an arc-shaped connector that inserts into both ends of the bent profile. Both ends of the arc-shaped connector have connecting slots corresponding to the cross-sectional shape of the bent profile. Both ends of the bent profile are inserted into the connecting slots of the arc-shaped connector. A radial venting flat section is formed on the arc-shaped connector. The system features an exhaust adapter installed on the outer arc surface of the arc-shaped connector, corresponding to the radial exhaust flat hole, to connect the exhaust flat hole to the exhaust pipe. This exhaust adapter is fixed to the arc-shaped connector using bolts, screws, or rivets. This separate structure makes the exhaust adapter and arc-shaped connector easier to manufacture, reducing production costs. Furthermore, the factory assembles only the profile bending body and the arc-shaped connector into a circular pot ring during shipment, while the exhaust adapter is packaged separately. This maximizes space utilization during transport, prevents damage to the exhaust adapter, and preserves the sealing performance at the joint between the profile bending body and the arc-shaped connector, ensuring the product's performance. The use of bolts, screws, or rivets to fix both ends of the profile bending body within the connecting slots of the arc-shaped connector further enhances the connection and fixation between the profile bending body and the arc-shaped connector. The use of a silicone sealing gasket between the arc-shaped connector and the exhaust adapter improves the sealing effect. Furthermore, the elasticity of the silicone gasket allows it to fill gaps caused by differences in curvature between the mating surfaces, enabling a single exhaust adapter model to seal with several arc-shaped connectors of varying radii. This saves on mold costs and further reduces manufacturing costs. The parallel connection faces at both ends of the profile bending body, along with the parallel sealing faces in the connecting slot, allow for equal angles and distances between the end faces of the profile bending body in circular pot rings of different diameters. This enables the use of parallel cutting tools with fixed intervals to cut the ends of profile bending bodies of different diameters, creating smooth connection faces that mate with the sealing faces of the connecting slots. This further reduces investment in production equipment. Because of the technical feature that the connecting end faces at both ends of the profile bending body and the sealing end faces at both ends of the connecting slot are all on a plane determined by the radius of the circular pot ring and the central axis, the mating accuracy between the connecting end face and the sealing end face is higher, and the required sealing effect can be achieved without the use of sealing gaskets.The use of a sealing gasket or sealant between the connecting end face of the profile bending body and the sealing end face of the connecting slot ensures a good seal between the connecting and sealing ends, compensating for steam leakage caused by insufficient machining precision. Furthermore, the inclusion of multiple fixing clips on the outer arc surface of the profile bending body that mate with the pot rim and secure the circular pot ring to the pot rim, connected to the profile bending body by bolts or screws, makes fixing the steam-free sealing pot ring to the pot rim of this invention more convenient.

[0019] Figure 5 This is a perspective view of the steam exhaust adapter in the steam-free sealed pot ring of this utility model. Detailed Implementation
[0020] like Figure 1 As shown, the steam-free sealing pot ring of this utility model includes a circular pot ring 1 with an upper edge that is water-sealed with the edge of the pot lid and a lower edge that is sealed with the edge of the pot by a rubber ring. A pot lid water seal ring groove 13 is provided on the upper edge of the circular pot ring, and a pot edge sealing ring groove is provided on the lower edge of the circular pot ring. A sealing rubber ring is embedded in the pot edge sealing ring groove.
[0021] like Figure 2As shown, the circular pot ring consists of a profile bending body 11 and an arc-shaped connector 12 that is inserted and fitted to both ends of the profile bending body. A sealing water groove is provided on the upper edge of the profile bending body, and a sealing groove for embedding a sealing rubber ring is provided on the lower edge of the profile bending body. Multiple fixing clips 3 are provided on the outer arc surface of the profile bending body to fit with the pot edge and fix the circular pot ring to the pot edge. The fixing clips are connected to the profile bending body by bolts or screws. Both ends of the profile bending body are respectively inserted into the connecting slots 125 of the arc-shaped connector. A radial steam venting flat hole 123 is opened on the arc-shaped connector. A steam venting adapter 2 is installed on the outer arc surface of the arc-shaped connector corresponding to the radial steam venting flat hole, which connects the steam venting flat hole to the steam venting pipe 4. The steam venting adapter is fixed to the arc-shaped connector by bolts 22, screws, or rivets.
[0022] like Figure 5 As shown, the steam exhaust adapter includes an arc-shaped mating edge 23 that mates with the arc-shaped outer arc surface of the arc-shaped connector, a steam output short pipe 25, and a transition pipe 24 that connects the arc-shaped mating edge and the steam output short pipe. The function of the steam exhaust adapter is to connect the steam exhaust flat hole with the steam exhaust pipe with a circular cross-section, so that the height of the circular boiler ring can be smaller than the outer diameter of the steam exhaust pipe.
[0023] Preferably, a silicone sealing gasket 21 is provided between the arc-shaped connector and the exhaust adapter, and the thickness of the silicone sealing gasket is not less than 5 mm. The silicone sealing gasket can be made into a double-arc, unequal-thickness silicone sealing gasket, that is, the arc radii on both sides of the silicone sealing gasket are unequal, being thinner at both ends and thicker in the middle, or as shown below. Figure 4 As shown, the overall shape is thicker at both ends and thinner in the middle, which allows the same exhaust adapter to be matched with sealing rings of various diameters. By producing the exhaust adapter as a general-purpose part, the cost is lower.
[0024] like Figure 3 As shown, a sealing groove 121 is provided on the upper edge of the arc-shaped connector, and a sealing groove 122 for embedding a sealing ring is provided on the lower edge of the arc-shaped connector. Connection slots 125 corresponding to the cross-sectional shape of the profile bending body are provided at both ends of the arc-shaped connector. The two ends of the profile bending body are fixed in the connection slots of the arc-shaped connector by bolts 15, screws, or rivets. Fixing holes are provided at both ends of the profile bending body and both ends of the arc-shaped connector.
[0025] Preferably, the connecting end faces 14 at both ends of the profile bending body are parallel to each other, and the two sealing end faces 124 in the connecting slot that mate with the connecting end faces of the profile bending body are parallel to each other. With this structure, after the profile bending body and the arc-shaped connector are assembled, the connecting end faces and the sealing end faces are parallel to each other, which facilitates the installation of a sealing gasket of equal thickness between the connecting end faces and the sealing end faces to compensate for the lack of tight sealing caused by insufficient processing precision and to ensure the effectiveness of use.
[0026] Preferably, the connecting end faces at both ends of the profile bending body and the sealing end faces at both ends of the connecting slot are all on a plane determined by the radius of the circular ring and the central axis. With this structure, if a sealing gasket is added between the connecting end face and the sealing end face, it is necessary to select a fan-shaped or wedge-shaped section sealing gasket of unequal thickness to ensure that both sides of the sealing gasket fit tightly against both the connecting end face and the sealing end face. However, when the machining accuracy of the connecting end face and the sealing end face is high enough, the connecting end face and the connecting slot using this structure can directly butt together or only require a very small amount of sealant to meet the sealing requirements, without the need for a sealing gasket.
[0027] When the steam-free sealing pot ring of this invention uses a 5mm silicone sealing gasket, a steam venting adapter of the same specification can be used to match several specifications of round pot rings. For example, a steam venting adapter with an arc-shaped butt joint edge and an arc surface radius of 375mm can be used to match all specifications of round pot rings with radii between 300mm and 450mm. If a double-arc surface silicone sealing gasket of unequal thickness is used, a steam venting adapter of the same specification can be used to match even more specifications of round pot rings, resulting in better versatility and lower manufacturing costs for the steam-free sealing pot ring.
