Atomizer and electronic atomization device

An electronic atomization device, comprising a body assembly and an atomizer, wherein the body assembly is connected to the atomizer and is configured to supply power for the atomizer, and the atomizer comprises:

• an atomization core assembly, configured to atomize liquid;
• a liquid storage assembly, comprising an inner barrel, wherein the inner barrel defines a slide cavity for receiving the atomization core assembly;
• and
• a mouthpiece assembly, disposed at an end of the inner barrel, wherein the mouthpiece assembly is configured to push the atomization core assembly to slide the atomization core assembly in the slide cavity, and an end of the atomization core assembly is capable of being exposed to an outside of the atomizer by being pushed by the mouthpiece assembly.

An atomizer, comprising:

• an atomization core assembly, configured to atomize liquid;
• a liquid storage assembly, defining a receiving channel, wherein the atomization core assembly is received in the receiving channel;
• and
• a mouthpiece assembly, disposed at a first end of the liquid storage assembly, wherein the mouthpiece assembly is configured to push the atomization core assembly to slide the atomization core assembly in the receiving channel, and an end of the atomization core assembly is capable of being exposed to an outside of the atomizer through a second end of the liquid storage assembly opposite to the first end.
