Description

Technical Field

[0001] This utility model relates to the field of heating wire design technology, and in particular to an adjustable power spiral heating wire structure. Background Technology

[0002] Heating wire is a component that converts electrical energy into heat energy. It is widely used in heating equipment, household appliances, industrial furnaces and other fields. According to its shape and use, it can be divided into spiral heating wire, corrugated heating wire, bag heating wire and composite heating wire.

[0003] Spiral heating wires are made by winding the wire into a spiral shape to increase the heat dissipation area and improve thermal efficiency. However, when the power exceeds the rated value, the heating wire remains at a high temperature, which accelerates oxidation and material fatigue, significantly shortening its lifespan. For example, a nickel-chromium alloy heating wire can have a lifespan of over 1000 hours at rated power, but if it is operated under a 20% overload, its lifespan may drop to less than 500 hours.

[0004] Therefore, it is necessary to provide an adjustable power spiral heating wire structure to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides an adjustable power spiral heating wire structure, which solves the problem that excessive power affects the lifespan of the heating wire.

[0006] To solve the above technical problems, this utility model provides an adjustable power spiral heating wire structure, comprising: a heating element, one end of which is provided with a circuit connection mechanism, the circuit connection mechanism including a winding component and a line connector, the winding component being used to wind heating elements of different lengths, and the line connector being used to connect to external devices;

[0007] An adjustment mechanism, comprising a rotating component, is used to drive the winding component to rotate in order to connect lines of different heating element lengths.

[0008] Preferably, one end of the heating element is provided with a connecting mechanism, which includes a protective component and a connecting component. The protective component is used for connection protection, and the connecting component is used to provide a channel for the connection between the circuit connector and external equipment.

[0009] Preferably, one end of the winding member is fixedly connected to a conductor, and the other end of the winding member is fixedly connected to an insulator. The winding member is used for circuit connection, and the insulator is used for connection and support while driving the winding member to rotate.

[0010] Preferably, a fixing member is connected to the surface of the rotating component, and a positioning mark is connected to one end of the protective component. The fixing member is used to connect and fix the rotating component, and the position of the heating element on the surface of different winding components can be determined by the position. The positioning mark is used to position the fixing member.

[0011] Compared with related technologies, the adjustable power spiral heating wire structure provided by this utility model has the following beneficial effects:

[0012] This invention provides an adjustable power spiral heating wire structure. By connecting heating elements of different lengths to the surfaces of multiple winding components, the length of the heating element on the corresponding winding component can be rotated to the circuit connection position by rotating the rotating component. This changes the length of the heating element, thereby changing the power of the heating wire, preventing excessive power and improving the service life of the heating element.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the first embodiment of an adjustable power spiral heating wire structure provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the protective component. An adjustable power spiral heating wire structure includes: a heating element 1, one end of which is provided with a circuit connection mechanism 3. The circuit connection mechanism 3 includes a winding component 32 and a line connector 34. The winding component 32 is used to wind up heating elements 1 of different lengths, and the line connector 34 is used to connect to external devices.

[0021] Adjustment mechanism 4 includes a rotating component 41, which is used to drive the winding component 32 to rotate in order to connect lines of different lengths of heating element 1.

[0022] There are four take-up pieces 32, and each take-up piece 32 has a heating element 1 of different lengths connected to its surface. One end is fixedly connected to a wiring connector 34. By connecting the wiring connector 34 at one end of the corresponding take-up piece 32 to an external device, the total circuit length of the heating element 1 is the sum of the lengths of the external heating element 1 and the heating element 1 on the surface of the take-up piece 32, thereby changing the resistance of the heating element 1. According to the formula P = U 2 / R, if a shorter heating wire is selected to connect to the circuit, the resistance will be smaller, and the power will be greater if the power supply voltage remains unchanged; conversely, if a longer heating wire is selected to connect to the circuit, the resistance will be larger, and the power will be smaller. The rotating part 41 is a disc-shaped component that is rotatably connected to the outer surface of the protective part 21.

[0023] One end of the heating element 1 is provided with a connecting mechanism 2. The connecting mechanism 2 includes a protective component 21 and a connecting component 22. The protective component 21 is used for connection protection, and the connecting component 22 is used to provide a channel for the connection of the line connector 34 to external equipment.

[0024] The protective component 21 is cylindrical. One end of the heating element 1 is fixedly connected to the inside of the protective component 21. The conductive element 31 is rotatably connected to one end of the heating element 1 embedded inside the protective component 21. The size of the connecting component 22 is larger than that of the line connector 34. When the line connector 34 rotates, the external device plug can be connected to the line connector 34 through the connecting component 22.

[0025] One end of the winding member 32 is fixedly connected to a conductor 31, and the other end of the winding member 32 is fixedly connected to an insulator 33. The winding member 32 is used for circuit connection, and the insulator 33 is used for connection and support while driving the winding member 32 to rotate.

[0026] The conductor 31 is a disc-shaped conductive material. One end of the heating element 1 connected to the surface of the winding member 32 is connected to the surface of the conductor 31. The insulator 33 is a disc-shaped insulating material. The other end of the winding member 32 is connected to the line connector 34 through the surface of the insulator 33, and the other end of the surface heating element 1 is connected to the corresponding line connector 34.

[0027] The surface of the rotating component 41 is connected to a fixing component 42, and one end of the protective component 21 is connected to a positioning mark 43. The fixing component 42 is used to connect and fix the rotating component 41, and the position of the heating element 1 on the surface of different winding components 32 can be determined by the position. The positioning mark 43 is used to position the fixing component 42.

[0028] The rotating component 41 is connected to the insulator 33 via a rod. When the rotating component 41 is rotated, the winding component 32 can be driven to rotate through the insulator 33, thereby causing the corresponding line connector 34 to rotate to the connecting component 22. There are four fixing components 42 arranged in a circular array on the surface of the rotating component 41, corresponding one-to-one with the four winding components 32. The power is marked at each fixing component 42. When the corresponding fixing component 42 rotates to the positioning mark 43, the corresponding line connector 34 rotates to the connecting component 22.

[0029] The working principle of the adjustable power spiral heating wire structure provided by this utility model is as follows:

[0030] According to the circuit connection of the heating element 1, the rotating part 41 is rotated, and the rotating part 41 drives multiple winding parts 32 to rotate circumferentially through the insulator 33 until the fixing part 42 corresponding to the winding part 32 connected to the heating element 1 of the corresponding length rotates to the positioning mark 43. At this time, the line connector 34 connected to one end of the winding part 32 is in the connecting part 22. Then, the bolt is inserted into the protective part 21 through the internal thread of the fixing part 42, and the rotating part 41 is fixed, thereby changing the length of the heating element 1 connected to the circuit. Then, the plug of the external power supply is connected to the line connector 34 through the connecting part 22. When working, the current flows through the line connector 34 to the heating element 1 that passes through the surface of the winding part 32 connected to it, and then through the conductor 31 to the surface of the external heating element 1.

[0031] Compared with related technologies, the adjustable power spiral heating wire structure provided by this utility model has the following beneficial effects:

[0032] This invention provides an adjustable power spiral heating wire structure. By connecting heating elements 1 of different lengths to the surfaces of multiple winding members 32, the length of the heating element 1 on the corresponding surface of the winding member 32 can be rotated to the circuit connection position by rotating the rotating member 41, thereby changing the length of the heating element 1 and thus changing the power of the heating wire, preventing excessive power and improving the service life of the heating element 1.
