Electronic cigarette with multiple temperature zones distributed in axial direction

Abstract

The invention discloses an electronic cigarette with multiple temperature zones distributed in axial direction, aiming at providing the electronic cigarette with multiple temperature zones distributed in axial direction, which is characterized in that multiple kinds of tobacco juice are vaporized under different temperature conditions. The electronic cigarette comprises a tube-shaped cigarette rod, a suction nozzle connected at one end of the cigarette rod and filled with an inner core, a plurality of smoking devices connected end to end, a battery and an LED lamp, which are sequentially arranged in the cigarette rod along the axial direction of the cigarette rod, from one end, close to the suction nozzle, of the cigarette rod to the end, far away from the suction nozzle, of the cigarette rod, a power supply switch arranged on the cigarette rod, and a transparent or semitransparent air vent housing with air vent holes arranged at the end part of the cigarette rod, wherein a smoke mixing cavity is connected at the joint of the cigarette rod and the suction nozzle; the smoking devices comprise thermal insulation sleeves sleeving inside of the cigarette rod, being in air-tight seal matching with the inner wall of the cigarette rod, and having the ends, facing the air vent housing being closed, PCT heaters arranged in the thermal insulation sleeves and being in mutual thermal conduction, and a radiator containing tobacco juice; and the power supply switch, the LED lamp and the PCT heater are electrically connected with one another. The electronic cigarette has the advantages that the purity of the taste is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an axially distributed multi-temperature heating electronic cigarette. Background technique [0002] Existing electronic cigarettes use a single heating body to complete the heating of the e-liquid. When the heating working temperature reaches the actual control value, the gasification and heating process of the e-liquid can be completed; since the e-cigarette must meet the physiological needs of consumers for smoking , all will be blended with various components of e-liquid in order to obtain products with superior aroma, irritation, fullness, dryness, etc. The boiling points of liquids are also different. In an electronic cigarette heater with a single working temperature, the e-liquid with a low boiling point is often evaporated first, and the e-liquid with a high boiling point is evaporated later, so that the same smoke is formed in the oral cavity. The ingredi...

In an electronic cigarette heater with a single working temperature, the e-liquid with a low boiling point is often evaporated first, and the e-liquid with a high boiling point is evaporated later, so that the same smoke is formed in the oral cavity. The ingredients in the initial stage will be different, which will affect consumers' evaluation of this electronic cigarette to a certain extent.
