Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermos flask technology, specifically a thermos flask with an exhaust vent in the lid. Background Technology
[0002] Thermos flasks are indispensable practical appliances in modern life. They feature a double-walled stainless steel or vacuum glass inner liner, achieving efficient heat preservation by blocking heat convection and conduction. Their core advantage lies in long-lasting temperature retention. The flask design balances portability and safety, equipped with a leak-proof silicone sealing ring, a one-button opening button, and an ergonomic handle. Some models also include a tea infuser or intelligent temperature display. Made of food-grade certified materials, they are corrosion-resistant and easy to clean, suitable for everyday household use, outdoor travel, and in-car use. Capacities range from 0.5L to 2L, meeting both individual drinking needs and sharing tea sets. Compared to traditional thermos flasks, thermos flasks are lighter and more durable, making them a preferred choice for those who pursue a quality lifestyle.
[0003] Existing thermos flasks with venting lids often contain hot water, which causes steam to accumulate and pressure to rise gradually as the flask is heated. When the user opens the lid again, the high pressure inside may cause hot water to suddenly splash out, resulting in burns. If the pressure accumulates excessively, it may even cause the flask to burst, thus increasing the risk of accidental injury during use. There is an urgent need to improve the safety of use through structural optimization. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a thermos with a ventable lid, which solves the problem that such thermoses are often used to hold hot water. Continuous heating causes steam to accumulate inside the thermos, and the pressure gradually increases. When the user opens the lid again, the high internal pressure may cause hot water to suddenly splash out, resulting in burns. If the pressure accumulates excessively, it may even cause the thermos to burst, thus increasing the risk of accidental injury during use.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a thermos with an ventable lid, comprising a body and a lid. The lid is rotatably connected to the top side of the body. A handle is fixedly connected to one side of the body, and a spout is fixedly connected to the top side of the body. A sealing plate is fixedly connected to the inner top side of the body, with a water outlet at the top of the sealing plate. A pressing plate is fixedly connected to one side of the lid, and the pressing plate and handle are located on the same side. A venting mechanism is provided between the bottom and top of the lid. In this invention, when the thermos is not in use, the lid is closed, and the water outlet on the sealing plate is blocked by a sealing plug, preventing water from flowing out of the body. When the thermos is in use, the body is lifted by the handle, and the pressing plate is manually pressed. The lid is then opened, and the sealing plug no longer blocks the water outlet, allowing water to be poured out through the water outlet and spout. The venting mechanism automatically vents air in one direction when the internal air pressure is high, preventing injury from excessive pressure inside the thermos when it is opened.
[0008] Preferably, the venting mechanism includes a sealing plug and an extension block. The sealing plug is fixedly connected to the bottom of the lid, and the extension block is fixedly connected to the top of the lid. The top of the sealing plug passes through the inner wall of the lid and is fixedly connected to the bottom of the extension block.
[0009] Preferably, a cavity is formed between the interior of the sealing plug and the interior of the extension block, and an air inlet is formed at the bottom of the sealing plug. Multiple air inlets are provided, and the multiple air inlets and the cavity are interconnected.
[0010] Preferably, an exhaust hole is provided on one bottom side of the extension block, a temperature sensor is fixedly connected to the top side inside the cavity, and a receiving cavity is provided inside the extension block.
[0011] Preferably, the receiving cavity is located outside the cavity, a micro-cooler is fixedly connected to one side of the extension block, the output end of the micro-cooler passes through the side wall of the extension block and extends into the interior of the receiving cavity, and a controller is fixedly connected to the back of the extension block.
[0012] Preferably, a movable block is slidably connected inside the cavity, and limiting blocks are fixedly connected to both sides of the movable block. Limiting grooves are formed on both sides of the cavity, and the limiting blocks are slidably connected inside the limiting grooves. A tension spring is connected between the bottom of the limiting block and the inner bottom wall of the limiting groove. In this invention, when the movable block moves up and down inside the cavity, the limiting blocks move in the limiting grooves, thereby preventing the movable block from rotating in the cavity and making the movement of the movable block more stable. Furthermore, the tension spring can keep the movable block tightly pressed against the air inlet when there is no exhaust, preventing air leakage.
[0013] In this invention, when the air pressure inside the kettle is high, the gas is first released through the air inlet into the cavity. Due to the air pressure, the moving block is pushed to the top of the cavity, allowing the gas to escape through the exhaust port. This process continues until the air pressure inside the kettle decreases, at which point the moving block is pulled back to its original position by the tension spring, blocking the air inlet. Simultaneously, the exhaust port, located at the top of the moving block, stops releasing gas. The gas inside the kettle is no longer released. A temperature sensor monitors the temperature inside the cavity. When the temperature of the gas inside the cavity is detected to be high, the controller activates a micro-cooler. The micro-cooler cools the containment cavity surrounding the main cavity. The temperature-transferable kettle lid further lowers the temperature inside the cavity, allowing the air inside the kettle to cool before being released. This prevents burns from excessively hot gas and improves user safety.
[0014] (III) Beneficial Effects
[0015] This utility model provides a thermos with an air-venting lid. It has the following beneficial effects:
[0016] (I) This thermos with an exhaust vent has an exhaust mechanism. When the internal air pressure is high, gas enters the cavity through the air inlet. Due to the air pressure, the moving block is pushed to the top of the cavity, and the gas can then be discharged through the exhaust vent. As the exhaust continues, the air pressure decreases, and the moving block returns to its original position, blocking the air inlet. Thus, the exhaust mechanism can automatically exhaust and seal when the internal air pressure increases, preventing excessive internal air pressure from causing danger and improving the safety of the thermos during use. Furthermore, it can only exhaust in one direction, preventing outside air from entering the inside of the thermos and preventing external contaminants from polluting the inside of the thermos, thus ensuring the hygiene of the thermos during use.
[0017] (ii) The thermos with an exhaust vent can monitor the gas temperature inside the kettle in real time through the setting of a miniature cooler, temperature sensor and containment cavity, and can also take cooling measures when the temperature inside the kettle is high to prevent people from being burned by the hot gas when opening the lid, thus improving the safety of people when using it.

[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] See Figures 1-4 This utility model provides a technical solution: a thermos with an exhaust vent, comprising a body 1 and a lid 2. The lid 2 is rotatably connected to the top side of the body 1. A handle 3 is fixedly connected to one side of the body 1. A spout 4 is fixedly connected to the top side of the body 1. A sealing plate 5 is fixedly connected to the inner top side of the body 1. An outlet 6 is provided at the top of the sealing plate 5. A pressing plate 7 is fixedly connected to one side of the lid 2. The pressing plate 7 and the handle 3 are located on the same side. An exhaust mechanism 8 is provided between the bottom and top of the lid 2. When the thermos is not in use, the lid 2 is closed, and the outlet 6 on the sealing plate 5 is blocked by the sealing plug 81, so that the water in the body 1 will not flow out. When the thermos is in use, the body 1 is lifted by the handle 3 and the pressing plate 7 is pressed manually. Then the lid 2 is opened, the sealing plug 81 is no longer blocking the outlet 6, so the water in the body 1 is poured out through the outlet 6 and the spout 4. The exhaust mechanism 8 can automatically exhaust air in one direction when the air pressure inside the body 1 is high, to prevent people from being injured when the body 1 is opened due to excessive air pressure.
[0025] The venting mechanism 8 includes a sealing plug 81 and an extension block 82. The sealing plug 81 is fixedly connected to the bottom of the lid 2, and the extension block 82 is fixedly connected to the top of the lid 2. The top of the sealing plug 81 passes through the inner wall of the lid 2 and is fixedly connected to the bottom of the extension block 82.
[0026] A cavity 83 is provided between the interior of the sealing plug 81 and the interior of the extension block 82. An air inlet 84 is provided at the bottom of the sealing plug 81. Multiple air inlets 84 are provided, and the multiple air inlets 84 and the cavity 83 are interconnected.
[0027] Among them, an exhaust hole 85 is provided on the bottom side of one side of the extension block 82, a temperature sensor 86 is fixedly connected to the top side inside the cavity 83, and a receiving cavity 87 is provided inside the extension block 82.
[0028] The cavity 87 is located outside the cavity 83. A micro-cooler 88 is fixedly connected to one side of the extension block 82. The output end of the micro-cooler 88 passes through the side wall of the extension block 82 and extends into the cavity 87. A controller 89 is fixedly connected to the back of the extension block 82.
[0029] The cavity 83 has a sliding connection to a movable block 810, and limit blocks 811 are fixedly connected to both sides of the movable block 810. Limit grooves 812 are opened on both sides of the cavity 83. The limit blocks 811 are slidably connected to the inside of the limit grooves 812. A tension spring 813 is connected between the bottom of the limit blocks 811 and the bottom wall of the limit grooves 812. Specifically, when the movable block 810 moves up and down inside the cavity 83, the limit blocks 811 move in the limit grooves 812, thereby preventing the movable block 810 from rotating in the cavity 83, making the movement of the movable block 810 more stable. In addition, the tension spring 813 can keep the movable block 810 tightly pressed against the air inlet 84 when there is no exhaust, preventing air leakage.
[0030] Specifically, when the air pressure inside the kettle body 1 is high, and the exhaust mechanism 8 is used to exhaust the gas, the gas first enters the cavity 83 through the air inlet 84. Due to the air pressure, the moving block 810 is pushed to the top of the cavity 83. At this time, the gas can be discharged through the exhaust port 85, thus achieving the exhaust function. Until the air pressure inside the kettle body 1 decreases, the moving block 810 is pulled back to its original position by the tension spring 813, thus blocking the air inlet 84. At the same time, the exhaust port 85 is located at the top of the moving block 810, and the exhaust port 85 no longer continues to exhaust gas. The gas inside body 1 stops being discharged. Temperature sensor 86 can monitor the temperature inside cavity 83. When the temperature of the gas inside cavity 83 is detected to be high, controller 89 controls micro-cooler 88 to work. Micro-cooler 88 cools the containment cavity 87 surrounding cavity 83. The temperature inside cavity 83 can be lowered through the temperature-transferable lid 2, thereby cooling the air inside body 1 before it is discharged, preventing the gas temperature from being too high and scalding people, thus improving the safety of people when using it.
