ELECTRONIC ATOMIZATION DEVICE AND ATOMIZER HAVING SAME

An electronic atomization device and an atomizer (100) having same. The atomizer (100) comprises an atomization component (130), a liquid storage cavity (141) connected to the atomization component (130) for liquid conduction, and a gas channel communicated with the atomization component (130) for gas conduction. The atomizer (100) further comprises a gas-liquid equilibrium element (150) and a gas inlet (1430) communicated with the gas-liquid equilibrium element (150). The gas-liquid equilibrium element (150) comprises liquid storage tanks (1510, 1520) with capillary force function and a gas return groove (153). One end of the gas return groove (153) is communicated with the liquid storage cavity (141), and the other end is communicated with the gas inlet (1430). The gas return groove (153) is communicated with the liquid storage tanks (1510, 1520) such that the liquid storage tanks (1510, 1520) are communicated with the liquid storage cavity (141). The gas-liquid equilibrium element (150) can balance the gas pressure in the liquid storage cavity (141), facilitate liquid discharge, prevent dry burning, and prevent liquid leakage caused by gas pressure imbalance.
