[0021] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 and Figure 6 The present invention relates to an anti-dry-burning heating tube, comprising an end base 1, an indicator light 2 fixedly installed on the outer side of the end base 1, a power connection wire 29 fixedly installed on the side of the end base 1 away from the indicator light 2, and a plug 30 fixedly installed on the end of the power connection wire 29 away from the end base 1, a base 3 fixedly installed at the bottom of the end base 1, a water level sensor 4 fixedly installed at the middle of the bottom end of the base 3, U-shaped heating tubes 5 symmetrically fixedly installed at the bottom of the base 3, and an adjustment and positioning component 6 installed on the outer side of the end base 1;

[0022] The adjusting positioning assembly 6 includes a top frame 7, which has a U-shaped structure. Fixing blocks 8 are symmetrically fixedly installed on the outer side of the end seat 1, and the two fixing blocks 8 are respectively fixedly connected to the inner side of the top frame 7 on the side away from the end seat 1. A circular frame 9 is fixedly installed at the middle of the top of the top of the top frame 7, and an opening 10 is symmetrically opened through the outer side of the circular frame 9. An adjusting block 11 is provided at the top of the circular frame 9, and an adjusting rod 12 is fixedly installed at the bottom of the adjusting block 11. The bottom of the adjusting rod 12 moves through and extends into the interior of the circular frame 9. A positioning shaft seat 13 is rotatably installed at the bottom of the adjusting rod 12, and the bottom of the positioning shaft seat 13 is fixedly connected to the middle of the top of the top of the top frame 7. A take-up and release wheel 14 is fixedly installed inside the circular frame 9 and outside the adjusting rod 12. Pull ropes 15 are symmetrically fixedly installed on the outer side of the take-up and release wheel 14.

[0023] The top of the top frame 7 is symmetrically provided with positioning crossbars 16, and the ends of the two positioning crossbars 16 that are close to each other are fixedly connected to the outside of the top frame 7. The ends of the two positioning crossbars 16 that are far from each other are fixedly installed with connecting blocks 17, and the bottom of the connecting blocks 17 is fixedly connected to the top of the top frame 7. The outer side of the end of the positioning crossbar 16 that is close to the connecting blocks 17 is slidably installed with a movable sleeve 18. Four positioning sliders 27 are symmetrically fixedly installed on the inner wall of the movable sleeve 18. Four positioning grooves 28 are symmetrically opened on the outer side of the positioning crossbar 16, and the positioning sliders 27 are slidably installed inside the positioning grooves 28. The top of the movable sleeve 18 is fixedly installed with a movable block 19, and the end of the pull rope 15 that is away from the take-up and release wheel 14 passes through the opening 10 and is fixedly connected to the movable block 19.

[0024] A movable ring 20 is fixedly installed on the side of the movable sleeve 18 away from the connecting block 17, and the movable ring 20 is slidably installed on the outside of the positioning crossbar 16. A positioning ring 21 is fixedly installed on the outside of the end of the positioning crossbar 16 away from the connecting block 17. A positioning spring 22 is fixedly installed between the positioning ring 21 and the movable ring 20, and the positioning spring 22 is sleeved on the outside of the positioning crossbar 16. A sliding block 23 is fixedly installed at the bottom of the movable sleeve 18. Sliding grooves 24 are symmetrically opened through the two ends of the top frame 7, and the sliding block 23 is slidably installed through the sliding grooves 24. A positioning frame 25 is fixedly installed at the bottom of the sliding block 23, and both positioning frames 25 are inverted L-shaped structures. The two positioning frames 25 are symmetrically arranged at the bottom of the top frame 7. An arc-shaped positioning block 26 is fixedly installed on the side of the two positioning frames 25 away from each other.

[0025] During use, the interaction of the end seat 1, base 3, water level sensor 4, U-shaped heating tube 5, and adjustment and positioning component 6 ensures that the anti-dry-boil heating tube is positioned in the center of the kettle container when directly inserted into it, improving its stability and reducing safety hazards, thus achieving better practicality. Furthermore, the interaction of the positioning slider 27 and positioning groove 28 ensures better stability when the movable sleeve 18 moves, thereby ensuring that the adjustment and positioning component 6 can work stably.

[0026] Working principle: During operation, first lift the top frame 7, then rotate the adjusting block 11, which drives the adjusting rod 12 to rotate. The adjusting rod 12 drives the take-up and release wheel 14 to rotate, and the take-up and release wheel 14 rotates to wind up the two pull ropes 15. The pull ropes 15 drive the movable block 19 to move. The movable block 19 drives the movable sleeve 18 to slide on the outside of the positioning crossbar 16 towards the end away from the connecting block 17. The movable sleeve 18 drives the positioning slider 27 to slide inside the positioning groove 28, which can ensure better stability of the movable sleeve 18 during movement. Meanwhile, the movable sleeve 18 drives the movable ring 20 to move, and the movable ring 20 compresses the positioning spring 22, causing the positioning spring 22 to undergo elastic deformation. At the same time, the movable sleeve 18 drives the sliding block 23 to slide inside the sliding groove 24, and the sliding block 23 drives the positioning frame 25 to move. At this time, the two positioning frames 25 move closer to each other, and the positioning frame 25 drives the arc-shaped positioning block 26 to move. When the distance between the two arc-shaped positioning blocks 26 is less than the diameter of the top port of the kettle container, the rotation of the adjusting block 11 stops.

[0027] Then, manually move the top bracket 7, and under the action of the fixing block 8, move the end seat 1. The end seat 1 drives the U-shaped heating tube 5 to move through the base 3, and inserts the U-shaped heating tube 5 into the inside of the kettle container, so that the top bracket 7 is located at the top of the kettle container. After the two arc-shaped positioning blocks 26 are flush with the top port of the kettle container, release the adjusting block 11. At this time, under the rebound force of the positioning spring 22, push the movable ring 20 to reset. The movable ring 20 drives the movable sleeve 18 to reset. The movable sleeve 18 is in the sliding block 23. Under the connection action, the positioning frame 25 is driven to move back to its original position. The positioning frame 25 drives the arc-shaped positioning block 26 to move back to its original position. At this time, the two arc-shaped positioning blocks 26 move away from each other. The two arc-shaped positioning blocks 26 move to contact the inner wall of the top port of the kettle container respectively. Under the elastic force applied by the positioning spring 22, the two arc-shaped positioning blocks 26 are pressed against the inner wall of the kettle container port. Then the top frame 7 is released. At this time, the end seat 1 is positioned directly above the kettle container port, and the two U-shaped heating tubes 5 are located in the center area inside the kettle container.

[0028] Then, cold water can be added into the kettle. Once the cold water level reaches the height of the water level sensor 4, stop adding water and insert the plug 30 into the external power socket. Power is supplied to the end seat 1 under the action of the power cord 29. At the same time, the water level sensor 4 works and generates a sensing signal. The U-shaped heating tube 5 starts heating the cold water in the kettle. During the heating process, when the water level is lower than the height of the water level sensor 4, the U-shaped heating tube 5 stops working.

[0029] This ensures that the anti-dry-burning heating element is positioned in the center of the kettle container when directly inserted into it, improving its stability during use and reducing safety hazards, thus facilitating better practicality.
