The present application will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of an electronic atomization device provided in the present application; fig. 2 is a schematic structural diagram of the electronic atomization device shown in fig. 1 with a part of the housing removed.
