Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, specifically a leak-proof thermos cup. Background Technology

[0002] A thermos flask is generally a water-filled container made of ceramic or stainless steel with a vacuum layer. It has a lid that seals tightly, and the vacuum insulation layer slows down heat dissipation from the liquid inside, thus keeping it warm. The thermos flask evolved from the thermos bottle, and its insulation principle is the same; it's just that people made it into a cup for convenience.

[0003] During use, thermos cups may leak due to collisions or aging. Since the containers are mostly filled with high-temperature liquids, leaks can easily cause burns to users. In addition, when there is too much hot water inside the thermos cup, the lid will squeeze the hot water inside the cup when the user puts the lid on the cup, causing hot water to leak out.

[0010] Preferably, a connecting ring is provided on the top of the outer side of the sealing block, and the sealing block is connected to the first sealing ring through the connecting ring.

[0011] By adopting the above technical solution, the user can stably and securely install the first sealing ring on the sealing block through the connecting ring, preventing the first sealing ring from falling off during use.

[0012] Preferably, the sealing block has grooves at the middle and bottom of its outer side, and the grooves at the middle and bottom of the sealing block are respectively engaged with the second sealing ring and the third sealing ring.

[0015] By adopting the above technical solution, the second and third sealing rings overlap with the inner wall of the cup body to achieve a leak-proof effect.

[0016] Preferably, the sealing block has exhaust ports on both sides inside, and the exhaust ports on the sealing block are connected to the top of the cavity.

[0017] By adopting the above technical solution, after excess hot water enters the stepped channel, the air will be compressed inside the cavity and can be discharged through the exhaust port, so that the excess hot water can smoothly enter the stepped channel.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This leak-proof thermos cup is equipped with a sealing block, and a first sealing ring, a second sealing ring and a third sealing ring are provided on the sealing block. The first sealing ring, the second sealing ring and the third sealing ring cooperate to achieve a multi-level leak-proof effect. In addition, a stepped groove and a cavity are provided in the sealing block. When the user puts the cup lid on the cup body, if there is too much hot water in the cup body, the hot water will enter the stepped groove and the cavity, which can prevent hot water leakage during the connection between the cup lid and the cup body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides an embodiment of a leak-proof thermos cup, including a lid 1. A connector 2 is provided at the top of the lid 1, and an inner liner 3 is provided inside the lid 1. A sealing block 5 is installed in the middle of the inside of the lid 1 via the connector 2. A first sealing ring 4 is provided at the top of the outer side of the sealing block 5, a second sealing ring 6 is provided in the middle of the outer side of the sealing block 5, and a third sealing ring 7 is provided at the bottom of the outer side of the sealing block 5. A stepped groove 8 is provided at the bottom of the inside of the sealing block 5, and a cavity 9 is provided at the top of the stepped groove 8. A cup body 10 is installed at the bottom of the lid 1 via the inner liner 3. When the user uses the thermos cup, the first sealing ring 4, the second sealing ring 6, and the third sealing ring 7 provide multi-level leak prevention. The stepped groove 8 and the cavity 9 on the sealing block 5 cooperate to allow excess hot water to be pressed into the stepped groove 8 during the connection process between the lid 1 and the cup body 10, further enhancing the leak-proof effect.

[0027] In this embodiment, an installation port is provided at the middle position of the top of the cup lid 1. The size of the installation port on the cup lid 1 is adapted to the size of the connector 2. The cup lid 1 is fitted with the connector 2 through the installation port. The bottom of the outer side of the connector 2 is provided with threads. A threaded hole is provided at the middle position of the top of the sealing block 5. The connector 2 is threadedly connected to the sealing block 5 through the threads and the threaded hole. The worker can connect the connector 2 and the sealing block 5 through the threads on the connector 2 and the threaded hole on the sealing block 5, so that the sealing block 5 can be stably and firmly installed in the inner liner 3.

[0028] In this embodiment, a connecting ring is provided on the top of the outer side of the sealing block 5. The sealing block 5 is connected to the first sealing ring 4 through the connecting ring. The user can install the first sealing ring 4 stably and firmly on the sealing block 5 through the connecting ring to prevent the first sealing ring 4 from falling off during use.

[0029] In this embodiment, grooves are provided at the middle and bottom of the outer side of the sealing block 5. The grooves at the middle and bottom of the sealing block 5 are respectively engaged with the second sealing ring 6 and the third sealing ring 7. The second sealing ring 6 and the third sealing ring 7 can be stably and firmly installed on the sealing block 5 through the grooves, which can prevent the second sealing ring 6 and the third sealing ring 7 from falling off during use.

[0030] In this embodiment, the top of the second sealing ring 6 is slightly larger than the bottom of the second sealing ring 6. The second sealing ring 6 overlaps with the inner wall of the cup body 10. The top of both the outer side of the third sealing ring 7 and the inner side of the cup body 10 are provided with retaining rings. The upper retaining ring of the third sealing ring 7 overlaps with the upper retaining ring of the cup body 10. The top of the second sealing ring 6 is slightly larger than the bottom of the second sealing ring 6, making the second sealing ring 6 trapezoidal, which facilitates the assembly of the cup lid 1 and the cup body 10. The overlap between the second sealing ring 6 and the third sealing ring 7 and the inner wall of the cup body 10 can achieve a leak-proof effect.

[0031] In this embodiment, exhaust ports are provided on both sides inside the sealing block 5. The exhaust ports on the sealing block 5 are connected to the top of the cavity 9. After excess hot water enters the stepped groove 8, the air will be squeezed inside the cavity 9 and can be discharged through the exhaust ports, so that excess hot water can smoothly enter the stepped groove 8.

[0032] Working principle: When the user uses the thermos, the first sealing ring 4, the second sealing ring 6 and the third sealing ring 7 all overlap with the cup body 10, which can play a multi-level leak-proof role. The stepped groove 8 on the sealing block 5 cooperates with the cavity 9, so that during the connection between the cup lid 1 and the cup body 10, excess hot water will be pressed into the stepped groove 8, which further plays a leak-proof role.
