The invention relates to an electrical heating tobacco set comprising a tobacco nozzle, an electrical heater, a power source, a control system and a shell body. The tobacco nozzle is located at the upper end of the heater and is integrally connected with the heater. Heating materials are arranged on the inner wall of the heater and define a heating cavity, and the heating cavity contains tobacco products by laterally opening a movable cover. The outer side of the heating materials is provided with a thermal insulation reflecting layer composed of an isolation thermal insulation film and a temperature reflecting film, and the heat loss is reduced. The control system is used for collecting smoking signals and controlling on-off of the power source of the heating materials. The power source provides electricity for working of the system. As the heater adopts the mode of lateral opening, a user only needs to open the movable cover in the lateral direction of the heater when using the tobacco set, and then the tobacco products can be placed; the convenience and rapidness degree of user experience are improved greatly, and as the thermal insulation reflecting layer is arranged on the inner wall of the heater, and the heat loss of the heater is reduced.
