Description

Technical Field

[0001] This utility model belongs to the field of drinking vessel technology, specifically relating to a sealing structure for drinking vessels. Background Technology

[0002] Drinking vessels are commonly used containers in daily life. To ensure hygiene and ease of carrying, drinking vessels are all sealed with lids. To improve their sealing performance, the openings on the cup body and lid are often equipped with sealing elements. Existing sealing elements mostly use silicone sealing rings and sealing gaskets. When the cup lid is sealed, the above-mentioned sealing elements achieve a sealing effect by interfering with and squeezing the components of the drinking vessel. However, the squeezing force between the above-mentioned sealing elements and the components is fixed and cannot be adjusted according to the internal and external pressure of the drinking vessel. If the squeezing force is too small, it will affect the sealing effect; if the squeezing force is too large, it will be difficult to open and will affect the service life of the sealing elements. Summary of the Invention

[0003] This invention addresses the problem in existing technologies where the interference pressure between the sealing element and the drinking vessel components cannot be adjusted according to the internal and external pressures of the drinking vessel, by providing a sealing structure for the drinking vessel. The objective of this invention is achieved through the following technical solution: A sealing structure for a drinking vessel includes a sealing element and a rigid component. The sealing element includes a base and a sealing ring protruding from the base. The sealing ring is distributed around the area to be sealed. The sealing ring includes a beveled edge made of soft rubber. The beveled edge is annular and extends obliquely relative to the base. The beveled edge forms an interference compression with the rigid component. The beveled edge has a pressure-bearing inclined surface that receives the internal pressure of the drinking vessel. The inclination angle of the beveled edge decreases as the internal pressure of the drinking vessel increases, and the compressive force applied to the rigid component increases. Conversely, the inclination angle of the beveled edge increases as the internal pressure of the drinking vessel decreases, and the compressive force applied to the rigid component decreases.

[0004] Preferably, the drinking vessel has a pressure relief channel, and the free end of the inclined contact edge extends at least partially into the pressure relief channel, with the pressure-bearing inclined surface facing the internal pressure of the drinking vessel.

[0005] Preferably, the pressure relief channel is distributed inside the inclined contact edge, and the inclined contact edge is inclined inward toward the pressure relief channel.

[0006] Preferably, the sealing ring further includes an outer ring contact edge formed around the oblique contact edge, the outer ring contact edge also being made of soft rubber material, and forming interference compression with the rigid component.

[0007] Preferably, the outer ring contact edge is inclined relative to the substrate and is in the same direction as the inclined contact edge.

[0008] Preferably, the pressure relief channel is distributed outside the inclined contact edge, and the inclined contact edge is inclined outward toward the pressure relief channel.

[0009] Preferably, the sealing ring further includes an inner ring contact edge formed inside the oblique contact edge, the inner ring contact edge also being made of soft rubber material, and forming interference compression with the rigid component.

[0010] Preferably, the inner ring contact edge is arranged perpendicularly or obliquely relative to the substrate.

[0011] Preferably, the substrate is fixedly assembled onto the fixed component and / or movable component of the drinking vessel.

[0012] Compared with the prior art, this utility model has the following beneficial effects: This solution provides an adaptive and dynamically adjustable sealing structure, which solves the problem that the fixed extrusion pressure of traditional seals cannot balance sealing effect and service life; through ingenious mechanical structure design, it enables the seal to automatically adjust the extrusion pressure on hard components according to the internal pressure of the drinking vessel; by using the pressure-bearing inclined surface of the inclined contact edge, the fluid pressure is efficiently converted into the required sealing pressure, realizing the adaptive adjustment of sealing pressure with internal pressure, fundamentally solving the contradiction between sealing reliability and sealing durability; by adding sealing contact edges to the outer or inner periphery of the inclined contact edge, multiple sealing guarantees are formed, greatly improving the reliability of the entire sealing system.

Detailed Implementation

[0014] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example 1, such as Figures 1-3As shown, this embodiment discloses a sealing structure for a drinking vessel. Specifically, the sealing structure is disposed on a lid, which includes a fixed lid 10 and a functional disc 20. The functional disc 20 is rotatably disposed above the fixed lid 10, and a drinking spout is fixedly mounted on the functional disc 20. The fixed lid 10 is divided into sections with a drinking inlet, a direct drinking inlet, and a vent hole that communicate with the cup body. A straw is fitted below the drinking inlet. The functional disc 20 can rotate relative to the fixed lid 10 to an assembly position and a mating position. The mating position includes a direct drinking position, a drinking position, and a sealing position. When the functional disc 20 is in the direct drinking position, the drinking spout is sealed and connected to the direct drinking inlet. When the functional disc 20 is in the drinking position, the drinking spout is sealed and connected to the drinking inlet. When the functional disc 20 is in the sealing position, it blocks the drinking inlet, the direct drinking inlet, and the vent hole.

[0015] The sealing structure includes a sealing element 30 and a rigid functional disc 20. In this embodiment, two sealing elements 30 are provided, namely a first sealing element 33 and a second sealing element 34. The first sealing element 33 is located around the vent hole, and the second sealing element 34 is located around the drinking inlet and the direct drinking outlet. The sealing element 30 includes a base 31 and a sealing ring 32 protruding from the base 31. One or more sealing rings 32 can be provided on the base 31. The base 31 is fixedly assembled on the fixed cover 10, and the sealing rings 32 are distributed at the drinking inlet, the vent hole, and the direct drinking outlet. The outer sealing ring 32 includes a beveled edge 321 made of soft rubber. The beveled edge 321 is annular and extends obliquely relative to the base 31. The beveled edge 321 forms an interference compression with the function disk 20. The beveled edge 321 has a pressure-bearing inclined surface 3211 that bears the internal pressure of the drinking vessel. The inclination angle of the beveled edge 321 decreases as the internal pressure of the drinking vessel increases, and the compressive force applied to the rigid component increases. The inclination angle of the beveled edge 321 increases as the internal pressure of the drinking vessel decreases, and the compressive force applied to the rigid component decreases. The inclined contact edge 321, made of soft rubber, forms an interference compression with the function disk 20 to ensure sealing. The pressure-bearing inclined surface 3211 bears the internal pressure and achieves adaptive adjustment. When the internal pressure increases, the tilt angle of the inclined contact edge 321 decreases, increasing the compression force on the function disk 20, enhancing the seal and preventing leakage. When the internal pressure decreases, the tilt angle returns to normal, reducing the compression force, lowering the rotational resistance, and extending the life of the seal 30. This achieves dynamic self-adjusting sealing, taking into account both high-pressure leak prevention and low-pressure easy operation.

[0016] The drinking inlet, direct drinking inlet, and vent hole form a pressure relief channel. At least part of the free end of the inclined contact edge 321 extends into the pressure relief channel. The pressure-bearing inclined surface 3211 faces the internal pressure of the drinking vessel. The pressure relief channel is located inside the inclined contact edge 321. The inclined contact edge 321 is inclined inward toward the pressure relief channel to better bear the internal fluid pressure and efficiently convert the internal fluid pressure into the required sealing pressure. This achieves adaptive adjustment of the sealing pressure with the internal pressure, fundamentally solving the contradiction between sealing reliability and the durability of the sealing element 30.

[0017] The sealing ring 32 also includes an outer ring contact edge 322 formed around the oblique contact edge 321. The outer ring contact edge 322 is also made of soft rubber and forms an interference compression with the function disk 20. The outer ring contact edge 322 is inclined relative to the base 31 and is in the same direction of inclination as the oblique contact edge 321. The double sealing ring 32 design ensures the sealing of the core interface. Adding an outer ring contact edge 322 outside the adaptive oblique contact edge 321 forms a double seal, improving the sealing effect and the adaptive adjustment effect.

[0018] Example 2, as Figure 4 , Figure 5 As shown, this embodiment discloses a sealing structure for a drinking vessel. Specifically, the sealing structure is disposed on a lid, comprising a fixed lid 10 fixedly connected to the cup body, and a functional disk 20 rotatable relative to the fixed lid 10. A drinking spout is fixedly mounted on the fixed lid 10. The functional disk 20 is divided into a drinking inlet and a direct drinking inlet communicating with the cup body, and a straw is fitted below the drinking inlet. The functional disk 20 can rotate relative to the fixed lid 10 to an assembly position and a mating position. The mating positions include a direct drinking position, a drinking position, and a sealing position. When the functional disk 20 is in the direct drinking position, the drinking spout is sealed and connected to the direct drinking inlet. When the functional disk 20 is in the drinking position, the drinking spout is sealed and connected to the drinking inlet. When the functional disk 20 is in the sealing position, it blocks the drinking spout.

[0019] The sealing structure includes a sealing element 30 and a rigid functional disk 20. The sealing element 30 includes a base 31 and a sealing ring 32 protruding from the base 31. One or more sealing rings 32 can be provided on the base 31. The base 31 is fixedly assembled to the bottom of the fixed cover 10. The sealing rings 32 are distributed around the periphery of the hole structure. Each sealing ring 32 includes a beveled edge 321 made of soft rubber. The beveled edge 321 is annular and extends obliquely relative to the base 31. The beveled edge 321 forms an interference compression with the functional disk 20. The beveled edge 321 has a pressure-bearing inclined surface 3211 that bears the internal pressure of the drinking vessel. The inclination angle of the beveled edge 321 decreases as the internal pressure of the drinking vessel increases, and the compressive force applied to the rigid component increases. The inclination angle of the beveled edge 321 increases as the internal pressure of the drinking vessel decreases, and the compressive force applied to the rigid component decreases. The inclined contact edge 321, made of soft rubber, forms an interference compression with the function disk 20 to ensure sealing. The pressure-bearing inclined surface 3211 bears the internal pressure and achieves adaptive adjustment. When the internal pressure increases, the tilt angle of the inclined contact edge 321 decreases, increasing the compression force on the function disk 20, enhancing the seal and preventing leakage. When the internal pressure decreases, the tilt angle returns to normal, reducing the compression force, lowering the rotational resistance, and extending the life of the seal 30. This achieves dynamic self-adjusting sealing, taking into account both high-pressure leak prevention and low-pressure easy operation.

[0020] A pressure relief channel is provided between the function panel 20 and the fixed cover 10. At least part of the free end of the inclined contact edge 321 extends into the pressure relief channel, and the pressure-bearing inclined surface 3211 faces the internal pressure of the drinking vessel. The pressure relief channel is distributed outside the inclined contact edge 321, and the inclined contact edge 321 extends outward toward the pressure relief channel to better bear the internal fluid pressure and efficiently convert the internal fluid pressure into the required sealing pressure, realizing the adaptive adjustment of the sealing pressure with the internal pressure. The sealing ring 32 also includes an inner ring contact edge 323 formed inside the inclined contact edge 321. The inner ring contact edge 323 is also made of soft rubber and forms interference compression with the rigid component. The inner ring contact edge 323 is set vertically or inclined relative to the base 31. The double sealing ring 32 design ensures the sealing of the core interface. An additional vertical inner ring contact edge 323 is added inside the adaptive inclined contact edge 321 to form double protection.
