Atomizing unit and atomizing device

An atomizing device, comprising:

• an atomizing unit (2);
• a shell (1) that is hollow;
• and
• a base (3);
• wherein the atomizing unit (2) comprises:
• a tubular heating assembly (100);
• and
• a liquid conducting member (200);
• wherein the liquid conducting member (200) is wrapped around an outer periphery of the tubular heating assembly (100) or fitted to an inner peripheral surface of the tubular heating assembly (100);
• wherein the tubular heating assembly (100) comprises an annular connecting portion (10), at least two heating portions (20) connected to one end surface of the connecting portion (10) and arranged around the end surface, and electrode portions (30) connected to one end of the heating portions (20) away from the connecting portion (10);
• wherein each side of two opposite sides of one heating portion (20) faces to a corresponding side of its adjacent heating portion (20) with a gap (50) therebetween;
• and
• wherein the at least two heating portions (20) are connected in series through the connecting portion (10);
• wherein one end of the shell (1) is provided with an air outlet (110), and another opposite end of the shell (1) is opened to form an open end;
• wherein the base (3) is fitted to the open end of the shell (1), and the atomizing unit (2) is disposed in the shell (1) and inserted on the base (3);
• wherein the shell (1) is provided therein with an air duct (120) communicated between the air outlet (110) and the atomizing unit (2), and a liquid storage chamber (130) located on an outer periphery of the air duct (120) and in fluid communication with the liquid conducting member (200) of the atomizing unit (2).
