Description
Technical Field
[0001] This utility model relates to the field of thermal cookers, specifically a thermal cooker. Background Technology
[0002] A thermal food jar is used to cook food (especially soups) by placing it inside, pouring in boiling water, and then covering it with the lid to let it simmer for about 2 hours. The jar's heat retention function allows the food to cook at a temperature close to boiling water. It's a convenient and economical cooking appliance that combines the functions of stewing, braising, cooking, keeping food hot or cold, and is easy to carry. It resembles a cup in shape and consists of a body and a lid.
[0003] However, existing insulated food jars still have the following problems during use:
[0004] Existing thermal cookers often overcook vegetables, causing them to become mushy and potentially leading to the loss of some nutrients. Furthermore, carrying vegetables around is inconvenient. Therefore, it is necessary to develop a thermal cooker that can be used in the existing thermal cooker market. Utility Model Content
[0005] To address the shortcomings of existing technologies, conventional thermal cookers often overcook vegetables for extended periods, causing them to become mushy and potentially leading to the loss of some nutrients. Additionally, they are inconvenient to carry around with vegetables. Therefore, this invention proposes a thermal cooker.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a thermos flask, including a thermos flask body and a lid, wherein the thermos flask body is provided with an operating cavity, and the bottom surface of the operating cavity is symmetrically provided with a traction port. Two sets of fixing blocks are fixedly assembled on the bottom surface of the operating cavity, each set having two fixing blocks, and the two fixing blocks in each set are respectively located on both sides of the traction port. A guide rod is fixedly assembled between the two fixing blocks in each set. A double-threaded screw is movably assembled on the two sets of fixing blocks. The double-threaded screw has two external threads, and a traction block is threaded onto the external threads of the double-threaded screw. The traction block is movably assembled with the guide rod and the traction port. A connecting rod is fixedly assembled on each traction block. A semi-conical heat insulation cylinder is fixedly assembled at one end of each connecting rod. The two semi-conical heat insulation cylinders are located outside the traction port, and the end faces of the two semi-conical heat insulation cylinders are in contact with each other. The top of the semi-conical heat insulation cylinders is in contact with the inner top surface of the lid.
[0007] Preferably, the two external threads of the double-threaded lead screw are in opposite directions, and the external threads of the double-threaded lead screw are located between the two fixed blocks in each group.
[0008] Preferably, the inner wall of the semi-conical heat insulation cylinder is fixedly fitted with partition plates, which are located below the connecting rod, and the end faces of the two partition plates are fitted together.
[0009] Preferably, a feed pipe is fixedly mounted on the semi-conical heat insulation cylinder, and the inside of the feed pipe is in communication with the inside of the semi-conical heat insulation cylinder.
[0010] Preferably, the feed pipe is located below the partition plate at the internal connection point of the semi-conical heat insulation cylinder, and a threaded cap is threaded onto the feed pipe.
[0011] Preferably, a first equal diameter bevel gear is fixedly mounted on the double threaded screw, and the first equal diameter bevel gear is located between two sets of fixed blocks.
[0012] Preferably, a rotating rod is movably mounted on the thermos body, one end of which extends into the operating cavity, and a second equal-diameter bevel gear is fixedly mounted on one end of the rotating rod, with the second equal-diameter bevel gear and the first equal-diameter bevel gear being toothed together.
[0013] Preferably, a knob is fixedly mounted on the other end of the rotating rod, and the knob is located above the lid, with the thermos body and the lid being threaded together.
[0014] The advantages of this utility model are:
[0015] This invention allows vegetables to be fed into two semi-conical insulated cylinders through an inlet pipe after the threaded cap is unscrewed. Boiling water is then poured into the thermos jar. The two semi-conical insulated cylinders insulate the vegetables. The thermos jar and lid are then installed together to keep the boiling water warm. Before use, the double-threaded screw is rotated, causing the two external threads of the screw to rotate on the traction blocks. This allows the traction blocks to move on the guide rod and the traction port, causing the semi-conical insulated cylinders on the connecting rod to move away from each other. This allows the vegetables to be poured out of the semi-conical insulated cylinders and fall into the boiling water, facilitating the stewing process and preventing the vegetables from becoming mushy due to prolonged stewing, thus reducing the loss of nutrients.
