[0003] The core of the atomization device is a heating element and a liquid guide, and after the heating element and the liquid guide are in full contact, the heat generated by the heating body heats the liquid on the liquid guide to the boiling point to be atomized into atomized vapor. The contact between the heating element and the liquid guide affects the stability and consistency of the atomization effect. Poor contact between the heating element and the liquid guide can cause the heating body temperature to rise, that is, the core is burnt, affecting the consumer experience.

In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0041] The present application provides an electronic atomization device 100, which comprises a heating atomization aerosol generating substrate, in the present embodiment, the aerosol generating substrate can be a liquid aerosol generating substrate, i.e. atomization liquid.

The power supply assembly can comprise a battery for supplying power to the atomizer. As shown in FIG. 1, the atomizer of an embodiment of the present application can be used to accommodate and heat the atomization aerosol generating substrate.

[0042] As shown in FIG. 1, in some embodiments, the atomizer comprises an atomization core 10 and a shell 20, the atomization core 10 is accommodated in the shell 20, the shell 20 is provided with a liquid inlet, and a liquid storage cavity is formed in the shell 20 for storing the aerosol generating substrate such as atomization liquid.
