Description

Electronic cigarette smoker and electronic cigarette

Technical field

The invention relates to the technical field of cigarette substitutes, in particular to an electronic cigarette smoker and an electronic cigarette.

Background technique

E-cigarette is an electronic product that imitates cigarettes, because the harmful components in tobacco will enter the user's body along with smoking, which will cause adverse effects on the health of the user and the people around him; and electronic cigarettes use chemical substances and various The e-liquid made of flavoring agent is heated and atomized to produce smoke, and the nicotine content can be controlled by controlling the composition of the e-liquid. Therefore, electronic cigarettes, which are mainly used for smoking cessation and replacing cigarettes, have been quickly promoted.

The existing atomizer of an electronic cigarette is a smoke generating device of an electronic cigarette. Injecting smoke oil into the atomizer and electrifying it can be used for smoking. In the existing atomizers, a heating wire is usually used to wind the oil-conducting cotton to heat and atomize the e-liquid, or a ceramic heating element is used to conduct the oil, and the e-liquid is energized to generate the smoke. The airflow during suction from the mouthpiece enters the user's mouth for the user to suck. However, if the oil guiding cotton/rope does not conduct enough oil at high temperature, it will cause the oil guiding cotton/rope to burn, which affects the suction taste and the service life of the atomizer; and the ceramic heating element may be carried or heated during high temperature. Dust is generated in the dust, and the dust is inhaled into the user's body with the smoke.

For the convenience of users, the existing electronic flue-cured cigarettes are generally provided with a heating chamber that can be opened and closed. The cigarettes are put into the heating chamber and heated to form smoke for users to use; generally speaking, heating wires are wound on the outer wall of the heating chamber to generate heat. After the wire is energized to generate heat, the heat is transferred to the heating chamber to bake the cigarette to make the tobacco high temperature to form smoke; or a metal heating plate is installed in the heating chamber and fixed at the bottom, and the metal heating plate is inserted into the cigarette axially when the cigarette is placed in the heating chamber Inside, the metal heating plate can be energized and heated to generate heat, which makes the tobacco form smoke for users to inhale. However, the heating wire wrapped around the outer wall of the heating chamber may cause the tobacco to not be cured completely due to uneven heating, and the greater heat may cause the shell to become hot; and the metal heating sheet may produce substances or dust that affect the absorption of taste at high temperatures, which may be inhaled with smoke The user's body.
