Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a heat-insulating sealing ring for a thermos cup lid. Background Technique

[0002] A thermos cup is generally a water container made of ceramic or stainless steel with a vacuum layer in between, which has the function of heat preservation and insulation. The principle of heat preservation is the same as that of a thermos flask. The vacuum insulation layer can slow down the heat dissipation of liquids such as water inside, so as to achieve the purpose of heat preservation.

[0003] A thermos cup consists of a cup body and a cup lid. The cup lid usually adopts a snap or threaded connection method. An existing thermos cup places a sealing ring at the opening connected to the cup lid to achieve a waterproof effect. The sealed structure can slow down heat dissipation. Due to different connection methods of the cup lid, the contact area between the cup lid and the cup body is relatively large, and the temperature of the liquid in the cup body conducts heat through the cup lid and loses heat. Therefore, the heat preservation time limit of the existing thermos cup is limited. Content of the Utility Model

[0006] A heat-insulating sealing ring for a thermos cup lid provided by the utility model includes a sealing ring body. The sealing ring body includes a waterproof ring and a heat-insulating ring. An exhaust channel communicating with each other is opened in the waterproof ring and the heat-insulating ring. Inner thread parts and outer thread parts are respectively arranged on the inner and outer sides of the heat-insulating ring, and a bottom cover is arranged at the lower end of the heat-insulating ring.

[0007] Further, the waterproof ring and the heat-insulating ring are of an integrally formed structure. The waterproof ring includes an upper edge and a lower edge, and the outer sides of the upper edge and the lower edge are connected to each other.

[0008] Further, a plurality of upper extrusion gaps and lower extrusion gaps are respectively opened at the upper and lower ends of the upper edge and the lower edge. The plurality of upper extrusion gaps and the lower extrusion gaps are arranged in an up-and-down corresponding manner.

[0009] Further, a plurality of anti-slip grooves are also opened on the inner wall of the waterproof ring, and the plurality of anti-slip grooves are arranged at equal distances with the waterproof ring as the center.

[0010] Further, a plurality of conical air holes are opened on the side of the waterproof ring, and the plurality of conical air holes communicate with the exhaust channel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following are specific embodiments of the present invention in combination with the accompanying drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0021] Embodiment

[0022] As Figures 1-4 shown, a heat-insulating sealing ring for a thermos cup lid includes a sealing ring body, the sealing ring body includes a waterproof ring 1 and a heat-insulating ring 2, an exhaust passage 3 communicating with each other is arranged inside the waterproof ring 1 and the heat-insulating ring 2, an internal thread portion 21 and an external thread portion 22 are respectively arranged on the inner and outer sides of the heat-insulating ring 2, and a bottom cover 23 is arranged at the lower end of the heat-insulating ring 2.

[0023] The waterproof ring 1 and the heat insulation ring 2 are of an integrally formed structure. The waterproof ring 1 includes an upper edge 11 and a lower edge 12. The outer sides of the upper edge 11 and the lower edge 12 are connected. The upper end of the upper edge 11 is matched and installed with the lower edge of the cup lid. The lower edge 12 is matched with the cup mouth part of the cup body. A plurality of upper extrusion gaps 111 and lower extrusion gaps 121 are respectively formed at the upper and lower ends of the upper edge 11 and the lower edge 12. After the cup lid and the cup body are closed, a closing pressure is generated through extrusion by the upper extrusion gaps 111 and the lower extrusion gaps 121 to achieve sealing. The plurality of upper extrusion gaps 111 and the lower extrusion gaps 121 are arranged in an up-and-down corresponding manner. A plurality of anti-slip grooves 13 are also formed on the inner wall of the waterproof ring 1. The plurality of anti-slip grooves 13 are arranged at equal distances with the waterproof ring 1 as the center. The anti-slip grooves 13 surround the inner side of the cup lid. After fitting, an adsorption force is generated through the anti-slip grooves 13, so that a frictional force is generated between the sealing ring body and the cup lid to tightly fit. A plurality of tapered air holes 14 are formed on the side of the waterproof ring 1. The plurality of tapered air holes 14 communicate with the exhaust passage 3. The air extruded in the exhaust passage 3 is discharged upward through the plurality of tapered air holes 14.

[0024] The exhaust passage 3 is located between the internal thread part 21 and the external thread part 22. The upper end of the exhaust passage 3 is connected to the waterproof ring 1. The internal thread part 21 and the external thread part 22 are arranged in an internal and external corresponding manner. There is a certain distance between the upper ends of the internal thread part 21 and the external thread part 22 and the waterproof ring 1. The internal thread part 21 and the external thread part 22 are respectively matched with the external thread of the cup lid and the internal thread of the cup body. During the process of screwing the threads, the air in the exhaust passage 3 of the heat insulation ring 1 is extruded and discharged to achieve a sealing effect, thereby isolating the cup lid and the cup body to achieve a heat insulation effect.

[0025] During use, the heat insulation ring 2 is sleeved into the bottom of the cup lid. The internal thread part 21 is matched with the external thread of the cup lid in place. The waterproof ring 1 at the upper end of the heat insulation ring 2 fits with the lower edge of the cup lid. The two are firmly adsorbed through the plurality of anti-slip grooves 13 to prevent the cup lid from falling off during the screwing process. After the sealing ring body and the cup lid are installed, the cup lid is screwed into the cup body. During the screwing process, the air in the exhaust passage 3 in the heat insulation ring 2 is extruded. The air in the exhaust passage 3 is discharged upward from the plurality of tapered air holes 14. After the cup lid is screwed in place until there is no gap between the cup lid and the cup body, a comprehensive heat insulation and waterproof sealing effect between the cup lid and the cup body is achieved.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
