ATOMIZATION DEVICE

A three-dimensional heating atomization device includes a shell, a heating element, a first thermo-electrode lead and a second thermo-electrode lead, wherein a heating chamber is arranged in the shell, one end of the first thermo-electrode lead is connected with one end of the heating element, and one end of the second thermo-electrode lead is connected with the other end of the heating element, so that a bottom surface and a side surface of the heating chamber are both heated by one heating member, and three-dimensional heating is more uniform and efficient, thus being beneficial for improving an atomization effect. Moreover, the first thermo-electrode lead and the second thermo-electrode lead not only can be used for supplying electric energy to the heating element to heat the heating chamber, but also can form a thermocouple by using the first thermo-electrode lead and the second thermo-electrode lead, so that a temperature of the heating element is detected by the thermocouple to realize a temperature control function of the heating element, thus avoiding use of a temperature measurement accessory such as a temperature sensor, simplifying an internal structure of an atomizer product, reducing accessories needed by the whole product, and allowing assembly and use to be more convenient and efficient.
