[0002] Tea leaves, commonly known as tea, generally consist of the leaves and buds of the tea plant. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all beneficial to health. Tea beverages are one of the world's three major beverages. After harvesting, tea leaves require proper preservation, necessitating a new type of fire-resistant and fresh-keeping device.

[0003] Some existing storage facilities do not have fire prevention mechanisms when storing tea. When an open flame occurs, it is too late to extinguish it. In addition, after the existing fire extinguishing devices extinguish the fire, embers may remain in the tea. This could lead to a secondary open flame when exposed to oxygen, resulting in low safety. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a new type of fireproof and freshness-preserving device for tea, in order to solve the problem that some existing storage devices do not have fireproof mechanisms when storing tea. When an open flame occurs, it is too late to extinguish it. At the same time, some existing fire extinguishing devices leave embers in the tea after extinguishing the fire, which may cause a secondary open flame when exposed to oxygen, resulting in low safety.

[0005] Based on the above objectives, this utility model provides a novel fireproof and fresh-keeping device for tea, including a fresh-keeping machine shell, in which a placement box is uniformly and fixedly connected, and a fireproof component is provided inside the fresh-keeping machine shell.

Air chambers are opened on both sides of the cover plate, and an air pipe is fixedly connected to one side of each of the two air chambers. The upper end of the air pipe extends into the interior of the air cylinder and is slidably connected to the lower end of the air cylinder. A first spring is fixedly connected inside the air chamber, and a block is fixedly connected to the lower end of the first spring. A vertical rod is fixedly connected to the lower end of the block. Air ports are opened on both sides of the lower end of the cover plate.

[0007] Preferably, a limiting rod is fixedly connected inside the air cavity, and the wall of the limiting rod is slidably connected to the plug and the vertical rod.

[0008] Preferably, a hollow rod is fixedly connected inside the placement box, and the inner diameter of the hollow rod is the same as the diameter of the vertical rod.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figure 1-3 As shown, this utility model provides a novel fireproof and fresh-keeping device for tea, including a fresh-keeping machine shell 1. According to the prior art, it can ensure the freshness of tea. The fresh-keeping machine shell 1 has a placement box 4 evenly and fixedly connected inside. The tea that needs to be kept fresh is placed inside the placement box 4. The fresh-keeping machine shell 1 is equipped with fireproof components inside.

[0024] The fireproof component includes an electric rod 2 fixed to both sides of the upper end of the refrigerator casing 1. The electric rod 2 is a driving device. In the prior art, a cover plate 5 is fixedly connected to the lower end of the electric rod 2, and the electric rod 2 drives the cover plate 5 to move up and down. An air cylinder 3 is fixedly connected to the upper end of the refrigerator casing 1. A piston 7 is slidably connected inside the air cylinder 3, and the piston 7 can move up and down inside the air cylinder 3. A rod 8 is fixedly connected to the lower end of the piston 7, and the lower end of the rod 8 is slidably connected to the cover plate 5. When the cover plate 5 moves downward, it drives the rod 8, and the movement of the rod 8 drives the piston 7 to move downward. Both sides of the cover plate 5 are open. An air chamber 14 is provided, and an air pipe 9 is fixedly connected to one side of each air chamber 14. The air pipe 9 is used to guide air. The upper end of the air pipe 9 extends into the interior of the air cylinder 3 and is slidably connected to the lower end of the air cylinder 3. A first spring 18 is fixedly connected inside the air chamber 14. A block 15 is fixedly connected to the lower end of the first spring 18. The first spring 18 has a downward pushing force on the block 15. A vertical rod 13 is fixedly connected to the lower end of the block 15. Air ports 16 are opened on both sides of the lower end of the cover plate 5. Monitoring devices 12 are provided on both inner walls of the refrigerator shell 1. The internal components are monitored at all times through the monitoring devices 12.

[0025] The tea leaves that need to be preserved are placed inside the preservation machine casing 1. When an open flame occurs, the monitoring device 12 detects it and then controls the electric lever 2 to move the cover plate 5 downward. When the cover plate 5 moves downward, it moves the lever 8 downward. When the lever 8 moves downward, it moves the piston 7 downward. The air cylinder 3 is filled with carbon dioxide. When the piston 7 moves downward, it squeezes the carbon dioxide downward. The air pipe 9 also moves downward with the cover plate 5. The cover plate 5 moves the vertical rod 13 downward. The vertical rod 13 moves and contacts the placement box 4, which causes the block 15, which is fixedly connected to the vertical rod 13, to move upward relative to the cover plate 5, compressing the first spring 18. At this time, Carbon dioxide is allowed to pass through the trachet 9 into the gas chamber 14 and then exit from the gas outlet 16. Since carbon dioxide is denser than air, it moves downward inside the placement box 4, squeezing out the air. Then, the cover plate 5 continues to move downward, covering the top of the placement box 4, thus sealing it and preventing external oxygen from entering. This effectively blocks the fire. In the event of an open flame, the carbon dioxide can squeeze out the air inside the placement box 4, thus extinguishing the fire. At the same time, the cover plate 5 seals the top of the placement box 4, preventing oxygen from entering and thus preventing the fire from spreading, thereby improving the safety performance of the device.

[0026] like Figure 3 As shown, a limiting rod 17 is fixedly connected inside the air chamber 14. The rod wall of the limiting rod 17 is slidably connected to the block 15 and the vertical rod 13. The limiting rod 17 makes the block 15 and the vertical rod 13 more stable when they move.

[0027] like Figure 2 As shown, a hollow rod 6 is fixedly connected inside the placement box 4. The inner diameter of the hollow rod 6 is the same as the diameter of the vertical rod 13. When the vertical rod 13 moves down, it enters the interior of the hollow rod 6 and will not press on the tea leaves, thus avoiding damage to the tea leaves.

[0028] like Figure 2 As shown, there are two cover plates 5, one above the other. The two cover plates 5 are fixedly connected by a metal rod, and the lower cover plate 5 is connected to the air cylinder 3 by a pipe fitting.

[0029] like Figure 2 As shown, a gas filling valve 11 is provided at the lower end of the gas cylinder 3, through which carbon dioxide is filled into the interior of the gas cylinder 3.

[0030] like Figure 2As shown, rod 8 is a telescopic rod, and a second spring 10 is fixedly connected inside. When the cover plate 5 moves downward, the carbon dioxide inside the air cylinder 3 is not discharged because the vertical rod 13 is in contact with the inner wall of the placement box 4. The telescopic rod and the second spring 10 can prevent the air pressure inside the air cylinder 3 from being too high, so that the release of carbon dioxide is relatively stable and will not spray out all at once.

[0031] Working principle: The tea leaves to be preserved are placed inside the preservation machine casing 1. When an open flame occurs, the monitoring device 12 detects it and then controls the electric lever 2 to move the cover plate 5 downward. When the cover plate 5 moves downward, it moves the lever 8 downward. When the lever 8 moves downward, it moves the piston 7 downward. The air cylinder 3 is filled with carbon dioxide. When the piston 7 moves downward, it squeezes the carbon dioxide downward. The air pipe 9 also moves downward with the cover plate 5. The cover plate 5 moves the vertical rod 13 downward. The vertical rod 13 moves and contacts the placement box 4, which causes the block 15, which is fixedly connected to the vertical rod 13, to move upward relative to the cover plate 5, compressing the first spring 18. At this point, carbon dioxide passes through the trachet 9 into the interior of the gas chamber 14 and is then discharged from the gas outlet 16. Since carbon dioxide is denser than air, it moves downward inside the placement box 4, squeezing out the air. Then, the cover plate 5 continues to move downward, covering the top of the placement box 4, thus sealing the placement box 4 and preventing external oxygen from entering, thereby blocking the fire. In the event of an open flame, carbon dioxide can squeeze out the air inside the placement box 4, thus extinguishing the fire. At the same time, the cover plate 5 seals the top of the placement box 4, preventing oxygen from entering and avoiding the spread of the fire, thereby improving the safety performance of the device.
