Referring to FIG. 3 and FIG. 4 together, in the first embodiment of the present invention, the atomizing head 90a includes an atomizing head sleeve 91a, an atomizing unit 93a, and a partitioning piece 95a in which an atomizing chamber 910a is disposed. The atomizing head sleeve 91a is generally a tubular shape in which both ends penetrate each other, and includes a base 911a and a tube portion 912a provided on the base 911a. A pipe opening 913a communicating with the liquid storage pipe 50 is opened in the pipe wall of the pipe portion 912a, and a vent hole 914a communicating with the atomizing chamber 910a is opened at the top of the pipe portion 912a.

The atomizing assembly 93a is housed in the atomizing chamber 910a in a direction perpendicular to the axis of the atomizing head sleeve 91a, and includes a liquid guiding member 930a, a heat generating member 932a, and a fixing seat 934. The liquid guiding member 930a is substantially semi-cylindrical, and both ends of the axial direction thereof are formed through the receiving hole 9301.

The intake port 915b and the air outlet 916b communicate with each other through the bottom of the outer periphery of the heat generating element 932b. After the external airflow flows in through the air inlet 915b, the airflow flows to the bottom along the top of the outer circumference of the heat generating element 932b, and flows to the top along the bottom of the other side of the outer periphery of the heat generating element 932b and flows out through the air outlet 916b. In this way, the external airflow can bypass the entire heat generating member 932b in the atomizing chamber 910b, thereby reducing the temperature difference and improving the liquid accumulation problem.
