Atomizer and aerosol inhaling device having same

An atomizer, comprising:

• a main body;
• an atomizing component received in the main body;
• and
• a liquid chamber configured for receiving tobacco liquid, the atomizing component being configured for generating aerosol from the tobacco liquid;
• wherein the atomizing component and the liquid chamber cooperatively defining a liquid passage therebetween;
• the atomizer further comprises a liquid blocking element defining a notch, the liquid blocking element is capable of rotating relative to the main body between a first position where the liquid blocking element prevents the tobacco liquid in the liquid chamber from flowing into the liquid passage, and a second position where the notch is in alignment with the liquid passage, so that the tobacco liquid flows to the atomizing component via the liquid passage;
• and
• wherein the liquid blocking element defines a first groove and a second groove in an outer surface, the first and the second grooves cooperatively form a predetermined arc angle;
• the main body comprises an elastic pin matching with the first and the second grooves, when the liquid blocking element is rotated, the elastic pin is selectively engaged in the first or the second grooves.
