1. An atomizer of an electronic atomization device, comprising:
a housing provided with a liquid storage chamber for storing liquid and a liquid outlet channel communicated with the liquid storage chamber;
an atomization component mounted on the housing, the liquid storage chamber being capable of supplying liquid to the atomization component through the liquid outlet channel; and
an on-off component moveably connected to the housing and having a first station and a second station;
when the on-off component is located at the first station, the on-off component blocking the liquid outlet channel; and when the on-off component is located at the second station, the on-off component opening the liquid outlet channel;
wherein the housing comprises a body portion and an isolation portion connected to each other, the isolation portion and the body portion define a first chamber and a second chamber, the atomization component is partially received in the first chamber, and a remaining part of the first chamber except a space for receiving the atomization component forms the liquid storage chamber; and the on-off component is arranged in the second chamber; and
wherein the liquid outlet channel comprises a first through hole and a second through hole spaced apart on the isolation portion, the first through hole communicates the liquid storage chamber with the second chamber, and the second through hole is communicated with the second chamber and configured to supply liquid to the atomization component; a communicating chamber is concavely formed on a surface of the on-off component; when the on-off component is located at the first station, the on-off component blocks the first through hole so that the first through hole and the second through hole are isolated from each other; and when the on-off component is located at the second station, the first through hole, the communicating chamber and the second through hole are communicated with one another.
