Background technique

At present, the electronic hookah carbon on the market uses electric heating wire or electric heating sheet to generate heat, and heat is transferred to the tobacco leaf by heat radiation or heat conduction or heat convection generated by human smoking, and the tobacco leaf is heated to release the smoke. There are two main ways: First, The electric heating wire or the electric heating piece is arranged above the tobacco leaf, and the electric heating wire or the electric heating piece is provided with an air inlet. When the person smokes, the air enters from the air inlet, and the electric heating wire or the electric heating piece passes the electric heating wire. Or the heat generated by the electric heating piece is brought to the tobacco leaf, and then passes through the tobacco leaf through the air outlet hole at the bottom of the cigarette lighter to enter the air passage of the hookah assembly, but in the case of no smoking action, since the hot air is light, the heat will rise and pass through Air outlet , Moreover, the heat radiation generated by the electric heating wire or the electric heating sheet is free to radiate to the surroundings, the heat loss is large, and the thermal efficiency is low; the second type, the electric heating wire or the electric heating sheet is around or below the tobacco leaf, that is, the electric heating wire or the electric heating piece Set inside the smoker, the heat generated by the electric heating wire or the electric heating piece is directly transmitted to the tobacco through the cigarette smoker, although the smoke is directly contacted with the tobacco leaf, the method is the same as the first 1 The heating efficiency of the method is high, but it is easy to burn the tobacco leaves, affecting the taste of the smoke, and because the generated heat is concentrated under the tobacco leaves, the upper tobacco leaves cannot get enough heat, especially when there is smoking action, the outside air enters.
