In this embodiment, the oil storage chamber 160 and the air flow channel 170 are respectively located on opposite sides of the atomizer core 120, and at least part of the wall surface of the air flow channel 170 is defined by the atomizer core 120. The atomizer core 120 is in liquid communication with the oil storage chamber 160, and the liquid in the oil storage chamber 160 is heated and atomized to form an aerosol and discharged to the air flow channel 170.

[0036] According to the atomizer 100 of the embodiment of the utility model, the atomizer 100 includes a housing assembly 110, and an oil storage chamber 160, an air flow channel 170 and an atomizer core 120 are provided in the housing assembly 110. The oil storage chamber 160 and the air flow channel 170 are respectively located on opposite sides of the atomizer core 120, and at least part of the wall surface of the air flow channel 170 is defined by the atomizer core 120. The atomizer core 120 is in liquid communication with the oil storage chamber 160, and heats and atomizes the liquid in the oil storage chamber 160 to form an aerosol and discharges it to the air flow channel 170. In the atomizer 100 of the embodiment of the utility model, the oil storage chamber 160 and the air flow channel 170 are separated in parallel, and the air flow channel 170 no longer passes through the oil storage chamber 160, thereby greatly reducing the possibility of the atomized liquid being heated in advance in the oil storage chamber 160, thereby facilitating the maintenance of the quality of the atomized liquid in the oil storage chamber 160. In addition, since the conduction of heat from the air flow channel 170 to the oil storage chamber 160 is reduced, the phenomenon of atomized liquid being squeezed out due to thermal expansion of gas in the oil storage chamber 160 can be prevented, thereby reducing the possibility of liquid leakage.
