Description

Technical Field

[0001] This utility model relates to the field of anti-dry-burning metal heating tubes, specifically an anti-dry-burning metal heating tube structure. Background Technology

[0002] Anti-dry-burning metal heating elements are safe heating components with built-in temperature sensors that automatically cut off power when water shortage or dry burning is detected to prevent overheating damage. They feature a high-temperature resistant metal casing, provide even heating, and have a long lifespan. Widely used in water heaters, water dispensers, and other equipment, they ensure safe and energy-efficient operation.

[0003] A specific example of an existing anti-dry-burning metal heating pipe structure can be found in application number CN202020279257.6, which describes an electric heating metal pipe comprising a metal pipe body, an insulating connecting sleeve, an inner lining, an anti-corrosion layer, and a thermal insulation composite layer. The metal pipe body has insulating connecting sleeves at both ends, an inner lining on its outer surface, an anti-corrosion layer on the side of the inner lining away from the metal pipe body, and a thermal insulation composite layer between the anti-corrosion layer and the inner lining. The insulating connecting sleeves provide insulation at the joints of the metal pipe body during use. The inner lining and anti-corrosion layer reinforce and support the anti-corrosion layer, preventing the thermal insulation composite layer from loosening after prolonged use and affecting the pipe's insulation performance. The organic polymer layer, foamed insulation layer, and insulating support block provide insulation when the metal pipe body generates heat, preventing rapid heat loss and energy waste when the pipe is not powered. The aforementioned device does not have any easily replaceable components. When the metal heating tube ages and becomes damaged after long-term use and needs to be replaced, the existing device cannot easily remove the metal heating tube for later replacement. Therefore, a metal heating tube structure that prevents dry burning is proposed to address the above problem. Summary of the Invention

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 scope of protection of the present utility model.

[0016] Please see Figures 1-5As shown, a dry-burning-proof metal heating tube structure includes a dry-burning-proof heating tube 1; a connector 2 is provided at the top of the dry-burning-proof heating tube 1, and a mechanism for easy disassembly and assembly is provided between the dry-burning-proof heating tube 1 and the connector 2. The easy-to-disassemble mechanism includes a positioning plug 10, which is also located on the left and right sides above the anti-dry-burning heating tube 1. One end of the positioning plug 10 is inserted into the side end of the connector 2, and the positioning plug 10 is slidably connected to the connector 2. The top of the positioning plug 10 is designed with a bevel, and the bottom of the positioning plug 10 is fixedly connected to the top of the movable frame 11. The top of the anti-dry-burning heating tube 1 has a guide groove 12, and the inside of the guide groove 12 is fixedly connected to the first guide rod 13. The movable frame 11 is sleeved on the outside of the first guide rod 13, and the movable frame 11 is slidably connected to the first guide rod 13. The inner wall of the movable frame 11 is designed with a circular shape. During operation, the positioning plug 10 moves outward along the inside of the connector 2, and when the positioning plug 10 moves outward, it will drive the moving frame 11 to move outward along the outside of the first guide rod 13 inside the guide groove 12.

[0017] Furthermore, the left and right ends of the outer side of the first guide rod 13 are also fitted with first return springs 14. One end of the first return spring 14 is fixedly connected to the guide groove 12, and the other end of the first return spring 14 is fixedly connected to the movable frame 11. The first guide rod 13 is designed as a round rod. During operation, as the movable frame 11 moves outward, it will compress the first return spring 14 on the outer side of the first guide rod 13, causing it to contract.

[0018] Furthermore, the other end of the positioning plug 10 is fixedly connected to one end of the fixing frame 15, and the other end of the fixing frame 15 is fixedly connected to the fixing plate 16. The rear end of the fixing plate 16 is fixedly connected to the front end of the first fixing seat 17 near the lower position. The front end of the rotating push rod 18 is sleeved on the outer side of the rear end of the first fixing seat 17, and the rotating push rod 18 is rotatably connected to the first fixing seat 17. The rear end of the rotating push rod 18 is sleeved on the outer side of the front end of the second fixing seat 19, and the rotating push rod 18 is rotatably connected to the second fixing seat 19. The rear end of the second fixing seat 19 is fixedly connected to the front end of the pressing plate 20. The inner wall of the rotating push rod 18 is circular. During operation, the pressing plate 20 is pressed against the side of the anti-dry-burning heating tube 1. When the pressing plate 20 is pressed, it will drive the second fixed seat 19 to move. The second fixed seat 19 pushes the rotating push rod 18 to rotate along the outer side of the second fixed seat 19 and the first fixed seat 17, and drives the fixed plate 16 to move outward. At the same time, when the first fixed seat 17 drives the fixed plate 16 to move outward, it also drives the fixed frame 15 to move outward synchronously.

[0019] Furthermore, the middle position of the front end of the pressing plate 20 is fixedly connected to the rear end of the fixed plate 21, the front end of the fixed plate 21 is fixedly connected to the rear end of the second return spring 22, and the front end of the second return spring 22 is fixedly connected to the rear end of the anti-dry-burning heating tube 1. When in operation, pressing the pressing plate 20 will cause the fixed plate 21 to move synchronously, and the fixed plate 21 will compress the second return spring 22 to retract.

[0020] Furthermore, the top of the fixed plate 21 is fixedly connected to the bottom of the first fixed block 23. The first fixed block 23 is sleeved on the outside of the second guide rod 24, and the first fixed block 23 is slidably connected to the second guide rod 24. The front end of the second guide rod 24 is fixedly connected to the rear end of the anti-dry-burning heating tube 1. The second guide rod 24 is a round rod design. During operation, the fixed plate 21 will drive the first fixed block 23 to move, and when the first fixed block 23 moves, the first fixed block 23 will move along the outside of the second guide rod 24.

[0021] Furthermore, the connector 2 is also fixedly connected to the front and rear ends with a second fixing block 25. The second fixing block 25 is sleeved on the outside of the third guide rod 26, and the second fixing block 25 is slidably connected to the third guide rod 26. The bottom end of the third guide rod 26 is fixedly connected to the top end of the anti-dry-burning heating tube 1. The third guide rod 26 is a round rod design. During operation, pull connector 2 upwards. When connector 2 is pulled upwards, it will cause the second fixing block 25 to move along the outside of the third guide rod 26 until it is completely disengaged, thus completing the disassembly.

[0022] Working principle: When disassembly is required, first press the pressing plate 20 towards the side of the anti-dry-burning heating tube 1. When the pressing plate 20 is pressed, it will drive the second fixing seat 19 to move. The second fixing seat 19 pushes the rotating push rod 18 to rotate along the outer side of the second fixing seat 19 and the first fixing seat 17, and drives the fixing plate 16 to move outward. At the same time, when the first fixing seat 17 drives the fixing plate 16 to move outward, it also drives the fixing frame 15 to move outward synchronously. When the fixing frame 15 moves outward, it will drive the positioning plug 10 to move outward along the inside of the connector 2. When the positioning plug 10 moves outward, it will drive the moving frame 11 to move along the inside of the guide groove 12. As the guide rod 13 moves outward, the moving frame 11 compresses the first return spring 14 and retracts until the positioning plug 10 is completely disengaged from the connector 2. When the pressing plate 20 is pressed, the fixing plate 21 moves synchronously and compresses the second return spring 22. At the same time, the fixing plate 21 moves the first fixing block 23. When the first fixing block 23 moves, it moves along the outside of the second guide rod 24 and pulls the connector 2 upward. When the connector 2 is pulled upward, it moves the second fixing block 25 along the outside of the third guide rod 26 until it is completely disengaged, thus completing the disassembly.
