Abstract: The present disclosure discloses a tobacco leaf foliar spraying substance for reducing harmful ingredients in cheroot, a method for reducing carcinogenic components in flue-cured tobacco leaves and flue-cured tobacco shreds. The tobacco leaf foliar spraying substance contains a lotus leaf extract, the harmful chemical ingredients comprise N-nitrosonornicotine, 4-(N-methyl-nitrosamine)-1-(3-pyridinyl)-1-butanone, N-nitrosoanabasine and N-nitrosoanatabine. Foliar spraying is performed on a fertile field by using the lotus leaf extract before tobacco leaves are harvested and modulated, which not only significantly promotesagronomic characters and economic traits of tobacco and alleviates tobacco leaf browning but also effectively reduces harmful chemical ingredients unique to tobacco leaves, such as nitrosamine and nicotine.

Abstract: The present disclosure relates to electronic cigarettes, and in particular to a control method of an electronic cigarette and an electronic cigarette. The method includes: activating an electromagnetic heating component to output a predetermined output power at a first stage, so that a heating device heats up; feedback controlling the output power of the electromagnetic heating component through a first PID algorithm according to the temperature information of the heating device and a preset preheating temperature, so that the heating device reaches the preheating temperature; and after the heating device reaches the preheating temperature, adjusting the output power of the electromagnetic heating component at a second stage, so that the heating device keeps a target smoking temperature, the target smoking temperature being less than the preheating temperature. The control method of the electronic cigarette provided in the embodiment adopts a combination of PID algorithms and electromagnetic heating.

Abstract: A heating element for heating cigarette and a heater are disclosed, the heating element includes: a heating part at a proximal end of the heating element, with a longitudinal axis along the longitudinal direction of the heating element; the heating part is configured for inserting inside the cigarette along the longitudinal direction; a fixing part at a distal end of the heating element and secured with the heating part, the fixing part is provided with an air inlet; the heating part comprises an air flow path formed therein and extending along the longitudinal direction; the air inlet is in communication with the air flow path; the heating part is bored with an air hole that communicates the air flow path with outside the heating part, such that the air flow in the air flow path is flowing into the cigarette.

Abstract: A tobacco-heating smoking set includes: a first component and a second component, wherein the first component includes: a first housing and a bracket, wherein the bracket is fixed on the first housing, and a heating chamber is formed inside the bracket; the second component includes: a second housing and a heating component, the second housing is matched and engaged with the first housing to form a housing of the tobacco-heating smoking set, the heating component is fixed on the second housing, the heating component includes a heating element, the heating element is accommodated in the heating chamber and is configured for heating a cigarette, and the first component is capable of being removed from the second component to expose the heating element.
