The bearing seat 7 is provided with two symmetrical through holes 72, and two second assembly cylinders 73 are provided between the two through holes 72. Fixed cylinders 74 are respectively provided on both sides of the second assembly cylinder 73. The bearing seat 7 is fixed to the swivel 5 at the fixed cylinder 74 by screws. A placement plate 71 is provided on one side of one of the through holes 72. Two of the first assembly cylinders 52 extend upward through the bearing seat 7 at the through hole 72. An angle sensor is placed in the placement plate 71. After the power supply of the angle sensor is turned on, it is connected to the circuit board 9. The circuit board 9 is covered by the upper cover 6. The temperature index on the circuit board 9 and the temperature of the electric heater are observed from the upper cover 6. The circuit board 9 is also provided with a switch for controlling the temperature of the electric heater.

[0027] The gear transmission group 8 includes a first transmission gear 81, a second transmission gear 82, a third transmission gear 83 and a fourth transmission gear 84. The second transmission gear 82 and the third transmission gear 83 are transmission-connected and arranged between the first transmission gear 81 and the fourth transmission gear 84. The first transmission gear 81 and the fourth transmission gear 84 are arranged on the circumference of the first assembly cylinder 52, and the second transmission gear 82 and the third transmission gear 83 are arranged on the circumference of the second assembly cylinder 73. Limiting blocks 522 are symmetrically arranged on the circumference of the two first assembly cylinders 52, and the limiting blocks 522 are provided with fixing holes 521. The first transmission gear 81 and the fourth transmission gear 84 are arranged on the circumference of the first assembly cylinder 52.

The fourth transmission gear 84 is a semicircular fan-shaped gear, and the meshing teeth of the fourth transmission gear 84 are arranged on the side close to the third transmission gear 83. The meshing teeth of the first transmission gear 81, the second transmission gear 82, the third transmission gear 83 and the fourth transmission gear 84 are meshed with each other. Since the fourth transmission gear 84 is a semicircular fan-shaped gear, the two swivels 5 can drive the first electric heater 1 and the second electric heater 2 to fold or unfold between 0 and 180 degrees according to the gear transmission group 8.

[0028] The first electric heater 1 and the second electric heater 2 are respectively provided with a first vertical plate 12 and a second vertical plate 13, two first offset plates 121 are provided on one side of the first vertical plate 12, and two second offset plates 131 are provided on the side of the second vertical plate 13 close to the first vertical plate 12, and the side walls 11 are fixed to the outer sides of the first vertical plate 12 and the second vertical plate 13, and the top and bottom of the first vertical plate 12 and the second vertical plate 13 are respectively provided with an upper shell 3 and a lower shell 4, and the upper shell 3 is provided with an air outlet 31, and the lower shell 4 is provided with an air inlet 41, and the top and bottom of the first vertical plate 12 and the second vertical plate 13 are respectively provided with assembly convex 14, a connecting groove 32 matching the assembly protrusion 14 is provided in the upper shell 3 and the lower shell 4, and the upper shell 3 and the lower shell 4 are installed at the upper and lower ends of the first vertical plate 12 and the second vertical plate 13 through the cooperation of the assembly protrusion 14 and the connecting groove 32. The height of the first vertical plate 12 is consistent with that of the second vertical plate 13, and the height between the two first offset plates 121 is greater than the height between the two second offset plates 131; a heating wire is provided on the inner wall of the first vertical plate 12 and the second vertical plate 13 between the two first offset plates 121 and between the two second offset plates 131, and the connecting wire of the heating wire passes through the swivel 5 and then passes through the lower cover 61 to connect to the power supply.

[0029] A linkage plate 10 is provided between the first electric heater 1 and the second electric heater 2 , and two ends of the linkage plate 10 are respectively connected to two supporting seats 7 , so that the supporting seats 7 are always in a vertical state when the first electric heater 1 and the second electric heater 2 are folded or rotated.

[0030] When the foldable carbon fiber electric heater of the invention is folded: the meshing teeth of the first transmission gear 81, the second transmission gear 82, the third transmission gear 83 and the fourth transmission gear 84 are meshed with each other. Since the fourth transmission gear 84 is a semicircular fan-shaped gear, swinging the first electric heater 1 will cause the first electric heater 1 to fold toward the first electric heater 2 until the first electric heater 1 and the second electric heater 2 are parallel to each other. After the first electric heater 1 and the second electric heater 2 are parallel to each other, the first electric heater 1 is swung in the opposite direction to rotate the first electric heater 1 until the first electric heater 1 and the second electric heater 2 are flat. Similarly, swinging the second electric heater 2 is the same as swinging the first electric heater 1, and the first electric heater 1 and the second electric heater 2 can rotate freely between 0 and 180 degrees.

[0031] When the foldable carbon fiber electric heater of the invention is internally ventilated and heated: the heating wire is fixed to the inner side surfaces of the first vertical plate 12 and the second vertical plate 13, and the first vertical plate 12 and the second vertical plate 13 are arranged in parallel in the electric heater. After the power is turned on, the heating wire heats up, and the cold air enters from the air inlet 41 in an "S" shape, is heated by the heating wire, and is discharged from the air outlet 31; wherein the first vertical plate 12, the second vertical plate 13, the first offset plate 101 and the second offset plate 201 can increase the residence time and contact area of ​​the cold air in the electric heater, increase the heating efficiency, and also prevent foreign matter and debris from directly entering the device from the air outlet 31 to damage the heating wire.

[0032] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
