It should be noted that the above embodiments only represent specific implementations of the electronic atomization device 1 in the present invention. Those of ordinary skill in the art may make some modifications and adjustments to the structure of the electronic atomization device 1 without departing from the concept of the present invention. For example, the atomizing core 15 can also be arranged in the connection control module 20, so that the liquid storage module 10 is only used to store the liquid matrix without performing atomization work, and the atomization work on the liquid matrix is performed in the connection control module 20, Correspondingly, the first electrode assembly 14 and the second electrode assembly 27 do not need to be provided in the liquid storage module 10 and the connection control module 20 .

Fig. 9 shows the electronic atomization device 1 in the second embodiment of the present invention. The main difference between it and the above-mentioned first embodiment is that the liquid storage module 10, the power supply module 30, and the connection control module 20 are vertically from top to bottom. Set in sequence.
