Description

Technical Field

[0001] This utility model relates to the field of sports water bottle technology, specifically a double-layer vacuum insulated sports water bottle. Background Technology

[0002] Double-walled vacuum insulated sports water bottles are designed specifically to meet the needs of sports enthusiasts for convenient drinking during exercise and maintaining a certain beverage temperature. Their structure typically features a double-walled design, consisting of an inner liner and an outer shell, with a vacuum layer formed between them. This vacuum layer is created by removing air from the space between the two layers using a special process, resulting in a near-air-free vacuum. Since air is a crucial medium for heat transfer, the vacuum layer significantly reduces heat transfer through conduction and convection, thus achieving highly efficient insulation.

[0003] Traditional water bottles often have cumbersome opening mechanisms, requiring either unscrewing the lid or using complex flip-top designs. These methods have several drawbacks in practical use. For example, their use is limited during exercise. During activities like running, cycling, and hiking, the user's hands are usually busy or need to maintain balance. Using a traditional water bottle with a screw-on lid requires stopping and freeing both hands, interrupting the workout and potentially leading to falls due to distraction. Water bottles with complex flip-top designs often require pressing multiple buttons and manipulating latches to open, which is time-consuming and laborious during exercise, hindering quick hydration and impacting the workout experience and performance. Furthermore, one-handed operation is difficult. When a user needs to use one hand for other tasks, such as carrying a child, lifting heavy objects, or driving, opening a traditional water bottle with one hand is inconvenient. Screwing the lid requires both hands, making it difficult to apply force with one hand. Complex flip-top designs also make it difficult to open the bottle entirely with one hand, preventing timely hydration and reducing usability. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that the traditional way of opening a water cup is rather cumbersome, requiring the lid to be unscrewed or a complex flip-top design. This opening and closing method has many shortcomings in actual use.

[0005] To address the aforementioned technical problems, this application provides a double-layered vacuum insulated sports water cup, comprising a shell and a lid. The lid is snapped onto the upper end of the shell. A first limiting buckle is fixedly installed on one side of the middle of the upper end of the lid.

A spring is fixedly installed on the upper end of the middle of the pressing buckle. One end of the spring is fixedly connected to a rotating shaft. A second limiting buckle is fixedly installed on one side of the lower end of the pressing buckle. A rotation groove is formed on the surface of the rotating shaft. Connecting rods are fixedly installed on both sides of the middle of the lower end of the rotating shaft. A rotating locking plate is fixedly installed on one end of each of the two connecting rods. A side sliding groove is formed on the outer side of the middle of the pressing buckle. The rotating locking plate is slidably snapped onto the middle of the side sliding groove.

[0006] In some embodiments, the upper end of the outer shell is fixedly connected to a bottle mouth, a limiting groove is formed below the middle of the bottle mouth, and notches are formed on both sides of the middle of the bottle mouth, and the limiting groove and the notches are connected.

[0007] In some embodiments, the two rotating plates are slidably engaged with the limiting slots, and the length of the limiting slots is less than the length of the notch.

[0008] In some embodiments, the limiting groove is slidably engaged with the limiting buckle one, the limiting buckle two is slidably engaged with the rotary groove, one end of the spring is fixedly connected to the press buckle, the other end of the spring is fixedly connected to the rotating shaft, and the lower end of the rotating shaft is rotatably connected to the partition.

[0009] In some embodiments, the push-button is slidably engaged with the outside of the rotating shaft, and the push-button is connected by engaging with the rotating groove opened on the surface of the rotating shaft through a limiting buckle two.

[0010] In some embodiments, the top of the bottle opening abuts against the partition, and a sealing ring is provided on the outer side of the connection between the bottle opening and the partition.

[0011] In some embodiments, an inner liner is fixedly installed in the middle of the outer shell, and a vacuum layer is formed between the outer shell and the inner liner.

[0012] In some embodiments, a cup sleeve is fitted onto the outer side of the outer shell, and the surface of the cup sleeve is uniformly provided with a plurality of through holes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a double-layer vacuum insulated sports water cup, including a shell 1 and a lid 2. The lid 2 is snapped onto the upper end of the shell 1. A limit buckle 1 25 is fixedly installed on one side of the middle of the upper end of the lid 2. A press buckle 21 is slidably snapped onto the middle of the upper end of the lid 2. A limit groove 22 is formed on one side of the press buckle 21. A partition 23 is formed in the middle of the lid 2. A spring 28 is fixedly installed on the upper end of the middle of the press buckle 21. One end of the spring 28 is fixedly connected to a rotating shaft 26. A limit buckle 29 is fixedly installed on one side of the lower end of the press buckle 21. A rotation groove 27 is formed on the surface of the rotating shaft 26. Connecting rods 30 are fixedly installed on both sides of the middle of the lower end of the rotating shaft 26. One end of each connecting rod 30 is fixedly installed with a... Rotate the locking plate 31. A side sliding groove 24 is provided on the outer side of the middle of the pressing buckle 21. The rotating locking plate 31 is slidably engaged with the middle of the side sliding groove 24. The two rotating locking plates 31 are respectively slidably engaged with the limiting groove 13. The length of the limiting groove 13 is less than the length of the notch 14. The limiting groove 22 is slidably engaged with the first limiting buckle 25. The second limiting buckle 29 is slidably engaged with the rotary groove 27. One end of the spring 28 is fixedly connected to the pressing buckle 21. The other end of the spring 28 is fixedly connected to the rotating shaft 26. The lower end of the rotating shaft 26 is rotatably connected to the partition plate 23. The pressing buckle 21 is slidably engaged with the outer side of the rotating shaft 26. The pressing buckle 21 is connected by engaging with the rotary groove 27 opened on the surface of the rotating shaft 26 through the second limiting buckle 29.

[0025] In this embodiment, the sliding engagement design of the pressing buckle 21 with the limiting buckle 25 and the limiting slide groove 22 enables quick one-handed opening and closing of the cup lid 2. During operation, the user only needs to press the pressing buckle 21, and the cup lid 2 can be easily unlocked by sliding the limiting buckle 25 within the limiting slide groove 22, eliminating the need for cumbersome twisting operations and greatly improving ease of use during operation. The cooperation between the spring 28 and the rotating shaft 26, as well as the sliding engagement between the rotating plate 31 and the limiting slot 13, form a double sealing guarantee. When the pressing buckle 21 is pressed down, the spring 28 is compressed, and the rotating shaft 26 drives the rotating plate 31 to rotate and engage with the limiting slot 13, tightly fixing the cup lid 2 to the outer shell 1. After the snap fastener 21 is pressed, the spring 28 rebounds, further enhancing the clamping force between the rotating plate 31 and the limiting slot 13. This effectively prevents liquid leakage during movement and ensures that the heat preservation and cold preservation effects are not affected. The sliding engagement between the limiting buckle 29 and the rotating groove 27, as well as the guiding effect of the side sliding groove 24 on the rotating plate 31, ensures that the snap fastener 21 is evenly stressed and moves smoothly during operation. This design not only avoids damage to the snap fastener 21 due to uneven stress but also prevents accidental opening, ensuring the safety of the water cup during carrying. At the same time, users can precisely control the opening and closing state of the rotating plate 31 by controlling the pressing force and angle, making the operation experience more flexible.

[0026] Example 2: As Figure 1-4 As shown, a bottle mouth 12 is fixedly connected to the upper end of the outer shell 1. A limiting groove 13 is opened at the lower part of the middle of the bottle mouth 12. Notches 14 are opened on both sides of the middle of the bottle mouth 12. The limiting groove 13 and the notches 14 are connected. The top of the bottle mouth 12 abuts against the partition 23. A sealing ring 15 is provided on the outside of the connection between the bottle mouth 12 and the partition 23. An inner liner 11 is fixedly installed in the middle of the outer shell 1. A vacuum layer is formed between the outer shell 1 and the inner liner 11. A cup sleeve 16 is sleeved on the outside of the outer shell 1. Multiple through holes 17 are evenly opened on the surface of the cup sleeve 16.

[0027] In this embodiment, the sealing ring 15 provided on the outer side of the contact point between the bottle mouth 12 and the partition 23 can tightly fill the gap between them. Combined with the snap-fit ​​structure of the cup lid 2 pressing buckle 21, the rotating locking plate 31, and the limiting slot 13, a double-seal protection is formed. During movement, the cup frequently shakes and flips; the sealing ring 15 and the mechanical snap-fit ​​structure work together to effectively prevent liquid leakage, avoiding wetting the item and ensuring that the vacuum layer is not invaded by liquid, maintaining long-term stable heat preservation and cold insulation performance. The vacuum layer between the outer shell 1 and the inner liner 11 greatly reduces heat transfer through conduction and convection, which is the core of achieving efficient heat preservation and cold insulation. At the same time, the tight fit between the bottle mouth 12 and the partition 23, and the presence of the sealing ring 15, further reduce the possibility of heat loss or transfer from the bottle mouth 12, extending the duration of hot water heat preservation and cold water cold preservation, meeting the user's needs for extended outdoor use. The temperature requirements of beverages during exercise are addressed by the limiting slot 13 and notch 14 on the bottle opening 12, which precisely cooperate with the rotating plate 31 of the lid 2. This ensures smooth opening and closing of the lid 2 while providing stable support for the connection between the lid 2 and the bottle opening 12, dispersing the external forces generated by collisions and squeezing during exercise, and preventing damage to the connection due to uneven force. The high-quality materials used in the outer shell 1 and inner liner 11, combined with a scientific structural design, make the water cup drop-resistant and wear-resistant, extending its service life. The evenly spaced through holes 17 on the outer side of the cup sleeve 16 reduce the weight of the cup sleeve 16 and improve breathability when holding it. When hands sweat a lot during exercise, it can prevent slippage between the hand and the cup sleeve 16 due to the accumulation of sweat, and increase the comfort of the hand contacting the cup sleeve 16. In addition, the cup sleeve 16 can also play a certain role in cushioning, reducing the impact force when the water cup is dropped, and protecting the outer shell 1 and inner liner 11 of the water cup.

[0028] like Figure 1-5As shown, this sports water bottle mainly consists of an outer shell 1, an inner liner 11, and a lid 2. The inner liner 11 is fixedly installed in the middle of the outer shell 1, forming a vacuum layer between the outer shell 1 and the inner liner 11. The vacuum layer can greatly reduce the heat transfer through conduction and convection, thereby effectively preventing the heat of the beverage inside the cup from exchanging with the external environment, achieving the effect of keeping drinks hot or cold. At the same time, a sealing ring 15 is provided on the outside of the connection between the bottle mouth 12 and the partition 23, further reducing the possibility of heat loss or transfer from the bottle mouth 12, enhancing the heat preservation performance. When it is necessary to open the lid 2, press the pressing buckle 21 by hand. The limiting groove 22 on one side of the pressing buckle 21 slides and engages with the limiting buckle 25 fixedly installed on one side of the upper middle part of the lid 2. When the pressing buckle 21 is pressed, it will slide along the limiting buckle 25. Simultaneously, the limiting buckle 29, fixedly installed on one side of the lower middle part of the pressing buckle 21, slides within the rotation groove 27 opened on the surface of the rotating shaft 26, causing the rotating shaft 26 to rotate. The connecting rods 30, fixedly installed on both sides of the lower middle part of the rotating shaft 26, drive the rotating plate 31 to rotate. The rotating plate 31 slides out from the limiting groove 13, releasing the lock on the cup lid 2. Since the limiting groove 13 and the notch 14 are connected, the rotating plate 31 can rotate out through the notch 14, thereby opening the cup lid 2 upwards. During this process, the spring 28 is compressed, storing elastic potential energy. When the cup lid 2 is placed back on the bottle mouth 12, the cup lid 2 is aligned with the bottle mouth 12 and placed down, so that the top of the bottle mouth 12 abuts against the partition 23. Then the pressing buckle 21 is released, the spring 28 releases elastic potential energy, driving the rotating shaft 26 to rotate in the opposite direction. Through the connecting rod 30, the rotating plate 31 slides back into the limiting groove 13, realizing the locking and fixing of the cup lid 2 and the bottle mouth 12, completing the closing action. The rotating plate 31 is slidably engaged in the side sliding groove 24 opened on the outer side of the middle of the pressing buckle 21. During the rotation, it plays a guiding and limiting role, ensuring that the movement trajectory of the rotating plate 31 is accurate, so that the opening and closing operation of the cup lid can be carried out stably and reliably.
