Referring to FIG. 4, the body portion 110 includes a shell 111 and a battery 101 arranged in the shell 111. As shown in FIG. 5, a first accommodating space A is arranged in the shell 111, and the first accommodating space A is configured for the atomization cartridge 121 to be mounted. It may be understood that the atomization cartridge 121 may be mounted in the shell 111 before use, or may be taken out of the atomization cartridge chamber 120 and mounted in the shell 111 when in use, which is not limited herein. In other words, the body portion 110 of this embodiment of this application may include the atomization cartridge 121, or may not include the atomization cartridge 121. As shown in FIG. 3 and FIG. 4, a second accommodating space B for storing at least one atomization cartridge 121 is arranged in the atomization cartridge chamber 120. The first accommodating space A is configured to removably receive the atomization cartridge from the second accommodating space B. The electronic atomization device 100 further includes an atomization core 112. A liquid substrate is stored in the atomization cartridge 121. The atomization core 112 is configured to heat the liquid substrate to generate an aerosol, and the battery 101 supplies power to the atomization core 112, so that the atomization core 112 heats the liquid substrate in the atomization cartridge 121 to form an aerosol.
The atomization core 112 may be arranged in the body portion 100 or in the atomization cartridge 121. In an embodiment, as shown in FIG. 4, the atomization core 112 is arranged in the body portion 110. Specifically, the atomization core 112 is arranged in the shell 111 of the body portion 110, and the atomization core 112 can receive an electric power of the battery 101 to heat the liquid substrate in the atomization cartridge 121 to form an aerosol. In another optional embodiment, the atomization core 112 may also be integrated in the atomization cartridge 121. One atomization core 112 is arranged in each atomization cartridge 121.
