The length of the temperature control band 13 corresponds to the period of the cosine function in fig. 6, so the length of the temperature control band 13 can be defined by the period of the corresponding cosine function. In addition, the length of the heating tube 1 determines the upper limit of the amplitude of the cosine function curve corresponding to the temperature control zone 13, and the diameter of the heating tube 1 determines the upper limit of the period of the cosine function curve corresponding to the temperature control zone 13. The circumference of the cross section of the heating tube 1 corresponds to the period of the cosine function curve.
In this embodiment, the value range of the amplitude a of the cosine function curve where the temperature control band is located is 10mm-80mm, and this range can fully ensure that different heating pipes all fall into this range, so that the heating pipes can perform zoned heating on the fuming medium, and simultaneously can preheat or/and keep warm another region when heating one region, so that the fuming medium can be released rapidly and continuously. The value range of the period t of the sine function curve or the cosine function curve of the temperature control zone 13 is 9.42mm-31.4mm, and the range enables media with different volumes to be well accommodated by the heater, so that the applicability of the heater is improved.
