Electronic atomization device and atomization assembly

An atomizer, comprising:

• a liquid storage portion defining a liquid cavity configured to store liquid to be vaporized;
• a heating assembly configured to heat and atomize the liquid flowing from the liquid cavity to the heating assembly;
• a sealing component, arranged between the liquid storage portion and the heating assembly, wherein the sealing component is configured to reduce leakage of the liquid flowing from the liquid cavity to the heating assembly;
• and
• one or more spaces formed between the sealing component and the liquid storage portion or the heating assembly, wherein the one or more spaces are configured to allow external air to flow to the liquid cavity.
