Therefore, the atomizer base assembly 1, atomizer 100 and electronic atomization device provided by the utility model can effectively solve the problem of easy leakage at the position of the electrode sheet 102 of the existing atomizer 100.

[0051] In this embodiment, the atomizer 100 further includes a hard bracket 6 and a soft rubber sleeve 7 .

The soft rubber sleeve 7 is sleeved on the insulating base 101 of the atomizer base assembly 1 and is provided with an atomizer core mounting groove 701 for mounting the atomizer core assembly 3.

[0053] The atomizer core assembly 3 is installed in the atomizer core installation groove 701 , and the lower end of the atomizer core pin 301 of the atomizer core assembly 3 extends downward to the electrode sheet 102 through the bracket threading hole 601 so as to abut against the electrode sheet 102 .

[0054] The soft rubber sleeve 7 and the nozzle housing 2 surround a liquid storage chamber 202, and the side of the atomizer core assembly 3 is provided with an atomizer core inlet connected to the liquid storage chamber 202, and the top of the atomizer core assembly 3 is provided with an atomizer core outlet connected to the nozzle opening 201 of the nozzle housing 2.

[0064] S40: Put the soft rubber sleeve 7 on the upper part of the insulating base 101 so that the U-shaped structure abuts against the second power connection part 1023;

[0065] S50: Finally, the nozzle housing 2 is placed on the insulating base 101 to complete the assembly of the atomizer 100.

[0066] S60: After obtaining the assembled atomizer 100, the atomizer 100 is clamped onto the top of the battery assembly 200, and the elastic ejector pin 200a on the top surface of the battery assembly 200 abuts against the first power connection portion 1021 to achieve electrical conduction. The first power connection portion 1021 is electrically connected to the U-shaped structure 3011 at the bottom of the atomizer core pin 301 through the fixing portion 1022 and the second power connection portion 1023 in sequence, thereby supplying power to the atomizer core assembly 3.
