Geometric parameters of the scale-up experimental device and prototype EHTP stick.

Section	Parameter (mm)	Scale-up device	Prototype
Tobacco section	Length	54.00	13.50
	Diameter	31.20	7.80
Heater	Total length	70.00	19.00
	Heater length	50.00	12.00
	Diameter	6.00	2.15
	Insertion depth	50.00	13.80
Hollow section^a	Length	48.00	12.00
	Diameter	14.00	3.50
Hollow section^b	Length	80.00	10.00

Note. (1) “a” denotes the hollow section of 3.50 mm diameter in Figure 1, “b” denotes the hollow section of 5.20 mm diameter in Figure 1. (2) The scale-up experiment is only conducted on the tobacco section of the prototype tobacco product under equivalent criteria conditions (scaled-up by a factor of 4).
