- the first elongated portion 3712, the second elongated portion 3722, the third elongated portion 3732, and the fourth elongated portion 3742 are arranged clockwise and at equal intervals on the heating substrate 31.
- the current on the first elongated portion 3712 flows clockwise along the circumferential direction of the heating substrate 31 through the far-infrared coating 32 to reach the second elongated portion 3722, and the current on the first elongated portion 3712 runs along the heating substrate.
- the circumferential direction of 31 flows through the far-infrared coating 32 counterclockwise to reach the fourth elongated portion 3742, and the current on the third elongated portion 3732 flows clockwise through the far-infrared coating 32 along the circumferential direction of the heating substrate 31 to reach The current on the fourth elongated portion 3742 and the third elongated portion 3732 flows counterclockwise along the circumferential direction of the heating substrate 31 through the far infrared coating 32 and reaches the second elongated portion 3722.
- first and third long portions 3712 and 3732 are electrically connected to the positive pole of the power supply unit 5, and the second long portion 3722 and the fourth long portion 3742 are electrically connected to the negative pole of the power supply unit 5. connection.
- the first elongated portion 3712, the second elongated portion 3722, the third elongated portion 3732, and the fourth elongated portion 3742 in this embodiment will be coated
- the far-infrared coating 32 covering the outside of the heating substrate 31 is divided into four parts, which further shortens the flow distance of the current on the far-infrared coating 32 and further reduces the resistance of the far-infrared coating 32 in the current path.
- the thickness of the far-infrared coating 32 in this embodiment can be made thinner, which can further save costs and improve the market competitiveness of the low-temperature baking smoking set provided by this embodiment.
- the far-infrared coating 32 can also be divided into six parts, eight parts, and ten parts along the circumferential direction of the heating substrate 31 to conduct current, which further reduces the current in the far-infrared coating. Flow distance on layer 32.
