Document Type and Number:
WIPO Patent Application WO/2019/085554
Kind Code:
A1
Abstract:
Disclosed is a combined heating and smoking device for heating-non-burning tobacco. The combined heating and smoking device comprises a main heating machine and a filtering and cooling device (1), wherein the main heating machine comprises upper cover high-temperature-resistant silica gel (3), an outer aluminium-alloy tube (5), a heat-insulating housing (6), an inner aluminium-alloy tube (7), lower cover high-temperature-resistant silica gel (8), a tobacco tube (9), one or more heating tubes (11), a PCBA, a battery (14), and one or more groups of heating wires (15); one group of heating wires (15) is installed on each of the heating tubes (11); one heat-insulating tube (16) is installed between every two adjacent heating tubes (11); the heat-insulating tube (16) is connected to the heating tubes (11) at upper and lower ends; the tobacco tube (9) is inserted in one or more heating tubes (11) from the bottom; and tobacco (10) is inserted in the tobacco tube (9), and non-burning-heating of the tobacco (10) is realized by the heating wires (15) at the outside of the heating tubes (11). According to the device, plurality groups of aluminium-alloy tubes treated with anodic oxidation and a plurality groups of PEEK-material heat-insulating tubes (16) are combined to constitute a device used for segmented heating and smoking a cigarette, providing a relatively high heating efficiency and a relatively low temperature of the outer surface.
