[0003] Based on the above problems existing in the prior art, designing a pressure relief device which does not destroy the integrity of the cup body and facilitates the pressure relief inside the cup body becomes the problem to be solved by this application. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a pressure relief device, including: a mounting carrier, provided with a mounting groove, and a pressure relief hole is arranged in the mounting groove; the pressure relief hole is arranged at the bottom of the mounting groove, connecting the outside with the inside of the mounting carrier.

[0006] The valve mechanism is installed at the pressure relief hole arranged in the installation groove, and is used for opening or closing the pressure relief hole.

[0007] The elastic component is arranged in the mounting groove of the mounting carrier and is located between the valve mechanism and the mounting carrier to provide a closing force for the valve mechanism to seal the pressure relief hole.

[0008] By adopting the above technical solution, the arrangement of the pressure relief hole and the valve mechanism enables the device to quickly release the pressure inside the mounting carrier when needed, effectively preventing equipment damage or safety accidents caused by excessive internal pressure. The valve mechanism can flexibly open or close the pressure relief hole as needed, making the use of the device more controllable. The elastic component provides a stable closing force for the valve mechanism, ensuring its tight fit and sealing effect in the closed state, while providing a buffering effect during the pressure relief process to protect the valve mechanism and the pressure relief hole.

[0009] In addition to the above technical features, this application also makes improvements in the following aspects:

[0010] In some embodiments, the valve mechanism includes a sealing assembly and a pressure relief switch. The pressure relief switch is disposed on the upper portion of the sealing assembly. By pressing the pressure relief switch, the valve mechanism is opened to release pressure.

[0011] By adopting the above technical solution, the user only needs to press the pressure relief switch to easily open the valve mechanism for pressure relief. This design makes the operation process simpler and faster, and improves the user experience.

[0012] In some embodiments, the sealing assembly includes a sealing piston and a guide rod connected to the sealing piston.

[0013] The sealing piston is installed at the pressure relief hole through a guide rod. Under the action of the pressure relief switch and the elastic component, the guide rod can move up and down along the pressure relief hole to drive the sealing piston to open or close the pressure relief hole for sealing or pressure relief.

[0014] By adopting the above technical solution: under the joint action of the pressure relief switch and the elastic component, the guide rod can quickly respond to the operation command, drive the sealing piston to quickly open or close the pressure relief hole, and realize flexible pressure relief control. At the same time, the sealing plug and the sealing sleeve form a multiple sealing structure, which effectively prevents the leakage of liquid and ensures the sealing performance of the installation carrier in the closed state.

[0015] In some embodiments, the guide rod and the sealing piston are an integrated structure, the piston is disposed at one end of the guide rod, and the other end of the guide rod is connected to a pressure relief switch.

[0016] By adopting the above technical solution, this integrated structure not only improves the stability of the pressure relief device, but also enables the pressure relief switch to transmit force more quickly when triggered to drive the piston to move.

[0017] In some embodiments, the mounting groove is an injection-molded groove structure, which is integrally formed with the mounting carrier. The upper portion of the mounting groove is open and the bottom protrudes upward, forming a sealing structure that matches the sealing piston.

[0018] By adopting the above technical solution, this design not only enhances the overall structural strength and stability, but also simplifies the manufacturing process and reduces production costs.

[0019] In some embodiments, the pressure relief hole extends upward to form a limiting boss, and the limiting boss is used to install an elastic component. One end of the elastic component is sleeved on the guide rod and the limiting boss, and the other end abuts against the pressure relief spring.

[0020] By adopting the above technical solution, the installation position of the elastic component is directly integrated on the pressure relief hole, so that the structure of the pressure relief device is more compact and integrated, and the pressure relief performance is optimized.

[0021] In some embodiments, the sealing piston is shaped as a cone or an arcuate spherical structure.

[0022] By adopting the above technical solution, it is possible to better adapt to the shape of the pressure relief hole, form a tighter sealing environment, and evenly distribute the internal pressure, thereby improving the pressure resistance of the pressure relief device.

[0023] In some embodiments, the sealing piston is a rubber sealing plug, and a sealing sleeve is placed on the outside of the sealing piston. The sealing sleeve is an elastic rubber ring, and the sealing sleeve fully or partially wraps the outside of the sealing piston.

[0024] By adopting the above technical solution, the sealing effect is further enhanced and the leakage of liquid is prevented.

[0025] The second aspect of the utility model is to provide a mounting carrier, wherein the mounting carrier is a cup cover, and the cup cover is provided with the above-mentioned pressure relief device, which is installed inside the cup cover and is used to relieve pressure inside the cup body.

[0026] By adopting the above technical solution, the cup cover has good sealing and pressure relief capabilities. When the cup cover is tightly closed, the sealing component can ensure that the liquid inside the cup body will not leak. When pressure relief is required, the pressure relief device can quickly reduce the internal pressure while maintaining the sealing of the cup cover.

[0027] The third aspect of the utility model is to provide a thermos cup, comprising a cup body and a cup cover, wherein the cup cover is a cup cover equipped with a pressure relief device.

[0028] By adopting the above technical solution, the user only needs to perform simple operations to trigger the pressure relief device to achieve rapid pressure relief inside the cup body.

The present application can be implemented in other different forms and is not limited to the embodiments described herein.

[0041] 1. Explanation of Descriptive Terms in This Application

[0042] The embodiments provided in this application in conjunction with the technical solutions are intended to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art. It should be noted that unless otherwise specifically stated in this application, the relative arrangement of components described in these embodiments should be interpreted as merely exemplary, and not as a limitation to the technical solutions of this application.

These or other directional terms should not be understood as restrictive terms.

[0044] In the present application, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0045] In addition, this application does not discuss in detail the technologies and equipment known to ordinary technicians in the relevant fields, but where appropriate, the technologies and equipment should be considered as part of the specification.

[0046] The application scenario of the present application is mainly based on the thermal insulation container, and it can also be applied to other scenarios according to its function. Its application scenario is not restricted or limited by the specific embodiments recorded in this application.

[0047] Second, after a thermos cup or carbonated beverage cup is filled with hot water or carbonated beverages, the cup lid is often difficult to open or pops open due to the difference between the internal and external air pressures. The traditional solution is to install a pressure relief valve on the cup body, but this approach destroys the integrity of the cup body, is difficult to process, and is prone to leakage. This application specifically provides a technical solution to the above problem. The technical solution, working principle, and technical effect of this application are described in detail below in conjunction with specific embodiments.

[0048] like Figure 1 , Figure 2 As shown, the utility model describes a pressure relief device, which includes a mounting carrier 1, a pressure relief hole 3, a valve mechanism 4 and an elastic component 5.

[0049] The mounting carrier is provided with a mounting groove 2, and a pressure relief hole 3 is located at the bottom of the mounting groove 2, connecting the outside with the inside of the mounting carrier. The valve mechanism 4 is installed at the pressure relief hole 3, and is used to control the opening or closing of the pressure relief hole 3, and the elastic component 5 is arranged in the mounting groove 2, located between the valve mechanism 4 and the mounting carrier, to provide a closing force for the valve mechanism 4, and ensure its sealing in the closed state. Preferably, in this embodiment, the elastic component 5 is a coil spring.

[0050] Specifically, the device can quickly open the pressure relief hole 3 when needed to release the pressure inside the mounting carrier 1, thereby effectively preventing damage to the cup body or safety accidents caused by excessive internal pressure.

[0051] The valve mechanism 4 can open or close the pressure relief hole 3 as needed, making the use of the device more flexible and controllable. Under normal circumstances, the valve mechanism 4 remains closed to ensure the sealing inside the mounting carrier 1; when pressure relief is required, the valve mechanism 4 can be quickly opened to achieve rapid pressure relief.

[0052] The elastic component 5 provides a stable closing force for the valve mechanism 4, so that the valve mechanism 4 can fit closely to the pressure relief hole 3 in the closed state, ensuring a good sealing effect. At the same time, the elastic component 5 can also provide necessary buffering during the pressure relief process to protect the valve mechanism 4 and the pressure relief hole 3 from damage.

[0053] This pressure relief device can be used in various occasions that require pressure relief protection, such as pressure vessels, piping systems, chemical equipment, etc., providing reliable protection for the safe operation of these equipment.

[0054] Furthermore, the valve mechanism 4 of the pressure relief device includes a sealing component 41 and a pressure relief switch 42. The pressure relief switch 42 is arranged on the upper part of the sealing component 41. The user only needs to simply press the pressure relief switch 42 to open the valve mechanism 4 for pressure relief.

[0055] When in use, by pressing the pressure relief switch 42, the valve mechanism 4 can be opened quickly to quickly release the internal pressure, thereby achieving rapid pressure relief.

[0056] When the pressure relief switch 42 is not pressed, the sealing component 41 maintains a tight sealing state, effectively preventing liquid leakage and ensuring the sealing and safety during use.

[0057] The above design makes the operation process simpler and faster, thus improving the user experience.

[0058] like Figure 3 As shown, the sealing assembly 41 includes a sealing piston 401, a guide rod 402 connected to the sealing piston 401, and a sealing sleeve 403 arranged on the sealing piston 401. The sealing piston 401 is installed at the pressure relief hole 3 through the guide rod 402. Under the action of the pressure relief switch 42 and the elastic assembly 5, the guide rod 402 can move up and down along the pressure relief hole 3, driving the sealing piston 401 to open or close the pressure relief hole 3.

[0059] The sealing piston 401 is tightly matched with the pressure relief hole 3 , and the sealing sleeve 403 on the sealing piston 401 forms a multiple sealing structure, which effectively prevents liquid leakage and ensures the sealing performance of the mounting carrier 1 in the closed state.

[0060] In addition, the design of the guide rod 402 enables the sealing piston 401 to stably move up and down in the pressure relief hole 3, which not only ensures the accuracy of the sealing piston 401 when closing, but also ensures the smoothness of the pressure relief.

[0061] In summary, through the combined action of the pressure relief switch 42 and the elastic component 5, the guide rod 402 can quickly respond to the operation instruction, drive the sealing piston 401 to quickly open or close the pressure relief hole 3, and realize flexible pressure relief control.

[0062] In order to enhance the connection strength between the guide rod 402 and the sealing piston 401 , the guide rod 402 and the sealing piston 401 are designed as an integrated structure, the piston is arranged at one end of the guide rod 402 , and the other end of the guide rod 402 is connected to the pressure relief switch 42 .

[0063] The guide rod 402 and the sealing piston 401 are designed as an integrated structure, which enhances the connection strength between the guide rod 402 and the sealing piston 401, making them more stable and less prone to deformation or breakage when subjected to external force or internal pressure.

[0064] Since there is no gap between the piston and the guide rod 402, this integrated structure helps to form a more tightly sealed environment. When the pressure relief switch 42 is not triggered, the piston can fit tightly against the pressure relief hole 3, effectively preventing leakage of liquid.

[0065] The integrated design of the guide rod 402 and the sealing piston 401 enables the pressure relief switch 42 to transmit force more quickly when triggered, driving the piston to move, thereby quickly opening or closing the pressure relief hole 3. This improves the response speed of the pressure relief device and helps to quickly release pressure in an emergency.

[0066] The mounting groove 2 is an injection-molded groove structure, which is integrally formed with the mounting carrier, has an opening at the top and a protruding bottom, forming a sealing structure that matches the sealing piston 401 .

[0067] The upwardly protruding sealing structure at the bottom of the mounting groove 2 is closely matched with the sealing piston 401 to form multiple seals, effectively preventing the leakage of liquid, thereby ensuring the sealing performance of the pressure relief device in the closed state.

[0068] The injection molded groove structure is integrally formed with the mounting carrier 1 and seamlessly connected, which greatly enhances the overall structural strength and stability. This design makes the pressure relief device more compact and can withstand greater internal pressure.

[0069] The injection molding process makes the manufacturing process of the mounting slot 2 simpler and more efficient, reducing the production cost. At the same time, the one-piece molding design also reduces the assembly steps and improves the production efficiency.

[0070] In the present application, the pressure relief hole 3 extends upward to form a limiting boss 6 for installing the elastic component 5. One end of the elastic component 5 is sleeved on the guide rod 402 and the limiting boss 6, and the other end is in contact with the pressure relief spring. This design makes the structure of the pressure relief device more compact and integrated, while optimizing the pressure relief performance.

[0071] The pressure relief hole 3 is extended upward to form a limiting boss 6, and the installation position of the elastic component 5 is directly integrated on the pressure relief hole 3 without the need for additional installation components or space, thereby making the structure of the pressure relief device more compact and integrated.

[0072] At the same time, the design of the limiting boss 6 enables the elastic component 5 to be accurately installed and stably positioned, thereby optimizing the pressure relief performance. When pressure relief is required, the elastic component 5 can provide a stable closing force to ensure that the sealing piston 401 fits tightly against the pressure relief hole 3. When the pressure relief switch 42 is triggered, the elastic component 5 can respond quickly and drive the sealing piston 401 to move, thereby achieving rapid pressure relief.

[0073] The shape of the sealing piston 401 is set to a conical body or an arcuate spherical body structure, and the sealing piston 401 of the conical body or arcuate spherical body structure can better adapt to the shape of the pressure relief hole 3 and form a tighter sealing environment. This design helps to reduce the gap between the piston and the pressure relief hole 3, thereby preventing liquid leakage.

[0074] In addition, the use of a conical or arc-shaped spherical structure allows the sealing piston 401 to distribute pressure more evenly when subjected to internal pressure, avoiding local stress concentration, thereby improving the pressure resistance of the pressure relief device and enabling it to work stably under higher pressure.

[0075] Preferably, the sealing piston 401 is a rubber sealing plug, the outside of which is sleeved with an elastic rubber ring that fully or partially wraps around the outside of the sealing piston 401 .

[0076] The rubber sealing plug itself has good elasticity and deformation ability, and can fit tightly with the pressure relief hole 3 to form an effective seal. The fully or partially wrapped elastic rubber ring on the outside further enhances the sealing effect, fills the small gap between the piston and the pressure relief hole 3, and prevents liquid leakage.

[0077] Combined with the above description of the pressure relief device, the working principle of this device is as follows:

[0078] When the air pressure in the thermos cup or carbonated beverage cup increases due to the temperature difference between the inside and outside or the release of carbon dioxide by carbonated beverages, the air pressure inside the bottle will exceed the set value. At this time, the user only needs to gently press the pressure relief switch 42 on the mounting carrier, and the pressure relief switch 42 will drive the valve mechanism 4 to open and release the air pressure inside the bottle. When the air pressure drops to a balance with the external environment, the valve mechanism 4 is closed under the action of the elastic component 5, and the sealing performance of the mounting carrier is restored.

[0079] The utility model also provides a cup cover, on which the above-mentioned pressure relief device is arranged. The pressure relief device is installed inside the cup cover and is used to relieve pressure inside the cup body. When the cup cover is tightly closed, the sealing component 41 can ensure that the liquid inside the cup body will not leak; and when pressure relief is required, the pressure relief device can quickly reduce the internal pressure while maintaining the sealing of the cup cover.

[0080] The utility model also records a thermos cup, including a cup body and the cup cover. Through the design of an integrated pressure relief device, the thermos cup not only improves the safety of use, but also enhances the sealing and heat preservation performance. The user can trigger the pressure relief device through simple operation to achieve rapid pressure relief inside the cup body.

[0081] In summary, the pressure relief device, cup cover and thermos cup of the utility model realize an efficient, safe and easy-to-use pressure relief function through ingenious structural design and material selection, and provide a reliable solution for various occasions requiring pressure relief protection.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0083] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in the field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it is deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
