The invention discloses a porous
ceramic electronic cigarette heater. The porous
ceramic electronic cigarette heater comprises a porous
ceramic carrier, a heating layer and a power supply, wherein theporous ceramic carrier is used for attracting tobacco
tar, the heating layer covers the upper surface of the porous ceramic carrier and is used for heating the tobacco
tar, particularly, the heatinglayer is formed by
sintering resistance paste, the heating layer comprises a permeable heating layer permeating into the porous ceramic carrier, and the power supply is connected to the heating layerthrough a lead and used for supplying power to the heating layer. The provided porous ceramic
electronic cigarette heater has the advantages that heating is quick, the
power density is high, the thermal capacity is low, the small-scale integration is easy, the
impact resistance is strong, the porous ceramic electronic cigarette heater is low-temperature and environmentally-friendly, and the heavymetal
pollution does not exist, and the problems are solved that a traditional electronic cigarette heater has low heat efficiency, easy oxidation, brittle failure, change of a resistance value (power) and the like. The invention further provides a preparation method of the porous ceramic electronic cigarette heater and an electronic cigarette, and the preparation method of the porous ceramic electronic cigarette heater and the electronic cigarette have the above advantages.
