Atomization device with improved assembling features

An atomization device, comprising:

• a housing assembly comprising a first housing portion and an incentive assembly at least partially located in the first housing portion;
• the incentive assembly comprising an incentive element, a first wire and a second wire connected to the incentive element, and a first conductive piece and a second conductive piece connected to the first wire and the second wire, respectively;
• the first conductive piece comprising a first contact portion;
• the second conductive piece comprising a second contact portion;
• and
• a handle assembly comprising a casing assembly and a battery assembly at least partially installed in the casing assembly;
• the casing assembly comprising a second housing portion;
• the second housing portion comprising an arc-shaped groove and an extending protrusion protruding into the arc-shaped groove;
• the extending protrusion comprising a first wall portion, a second wall portion opposite to the first wall portion, and a receiving groove located between the first wall portion and the second wall portion;
• the first conductive piece and the second conductive piece being fixed on the extending protrusion;
• the first contact portion and the second contact portion being respectively located on two sides of the receiving groove, and are exposed in the receiving groove;
• wherein the battery assembly comprises a mounting seat, a built-in circuit board installed on the mounting seat, a battery installed on the mounting seat and electrically connected to the built-in circuit board, and a first conductive terminal and a second conductive terminal electrically connected to the built-in circuit board;
• the first conductive terminal comprises a first elastic arm;
• the second conductive terminal comprises a second elastic arm;
• and
• wherein the mounting seat comprises a docking boss;
• the docking boss comprises a first outer surface and a second outer surface opposite to the first outer surface;
• the first elastic arm protrudes beyond the first outer surface;
• the second elastic arm protrudes beyond the second outer surface;
• the docking boss is inserted into the receiving groove, so that the first elastic arm is in contact with the first contact portion, and the second elastic arm is in contact with the second contact portion.
