The second predetermined spacing 116 may be configured to prevent heat transfer between the first region 113 and the second region 114 caused by thermal conduction of the copper electrode sheet 1112 over the ceramic resistor 1111. In alternative embodiments, the second preset distance 116 may be another value greater than or equal to 5mm, as long as it is ensured that the second preset distance 116 is greater than the first preset distance 115, and the difference between the second preset distance 116 and the first preset distance 115 is less than or equal to 5mm, so as to ensure the uniformity of the outlet air temperature of the first area 113 and the second area 114.
