[0107] When assembling the atomizing device 100, the battery assembly 40 can be assembled first. At this time, the built-in circuit board 42 is installed in the first mounting slot 4110 of the first base 411. Both ends (e.g., the top and bottom ends) of the built-in circuit board 42 are respectively constrained between the first baffle 413 and the third baffle 416.

Simultaneously, the limiting slot 422 of the built-in circuit board 42 engages with the corresponding limiting post 4112. Then, the first connecting terminal 46 and the second connecting terminal 47 are electrically connected to the built-in circuit board 42.

The first gripper 4121 and the second gripper 4122 abut against the battery 43 to prevent the battery 43 from falling out. The first gripper 4121 and the second gripper 4122 are adaptive elastic holding structures, thereby compensating for assembly loosening caused by manufacturing errors or expansion caused by use. Then, the first conductive terminal 44a and the second conductive terminal 44b are inserted along the longitudinal direction of the mounting base 41 and pass through the mating boss 415. The first base 44a1 is fixed in the first fixing slot 4155; the second base 44b1 is fixed in the second fixing slot 4156.

Furthermore, by assembling the first conductive terminal 44a and the second conductive terminal 44b onto the mating boss 415, the first claw 44a2 and the second claw 44b2 can hold and fix the built-in circuit board 42. The shock-absorbing pad 45 is installed at the bottom of the second baffle 414.

[0108] The first conductive sheet 226a and the second conductive sheet 226b are respectively crimped and fixed to the first wire 225a and the second wire 225b. Then, the first conductive sheet 226a and the second conductive sheet 226b are assembled onto the extension protrusion 524 of the second housing portion 52.

[0109] Then, the battery assembly 40 is assembled into the internal space 511 of the handle portion 51 through the mounting opening 512 along the extending direction of the handle portion 51. The mating boss 415, together with the first elastic arm 44a3 and the second elastic arm 44b3, is inserted into the receiving groove 5240 of the extending protrusion 524. The first elastic arm 44a3 and the second elastic arm 44b3 elastically abut against the first contact portion 226a1 of the first conductive sheet 226a and the second contact portion 226b1 of the second conductive sheet 226b, respectively.

[0110] Then, the tail cap 53 is installed and fixed to the bottom end of the handle portion 51. The shock-absorbing pad 45 interacts with the tail cap and the handle portion 51, making the atomizing device 100 less prone to loosening and producing abnormal noise during use.

[0111] Then, the housing assembly 20 is assembled onto the handle assembly 10, with the first mounting protrusion 5211 and the second mounting protrusion 5221 of the housing assembly 50 respectively locking into the first mounting hole 2130 and the second mounting hole 2140 of the housing assembly 20. After assembly, the first inner wall 2131 and the second inner wall 2141 of the first housing portion 21 are received in the arcuate groove 520 of the second housing portion 52; the first inner wall 2131 of the first housing portion 21 is engaged with the inner side of the third side wall 521 of the second housing portion 52; the second inner wall 2141 of the first housing portion 21 is engaged with the inner side of the fourth side wall 522 of the second housing portion 52. The third side wall 521 is flush with and smoothly transitions to the outer surface of the first side wall 213, and the fourth side wall 522 is flush with and smoothly transitions to the outer surface of the second side wall 214.

[0112] Finally, the liquid storage tank assembly 30 is rotatably installed into the mounting cavity 210 of the housing assembly 20. Specifically, the protrusion 312 of the liquid storage tank outer shell 31 is first inserted obliquely into the mounting cavity 210, and then rotated downwards with the rotational hinge circular surface 3122 of the protrusion 312 as the fulcrum, so that the liquid storage tank assembly 30 is finally installed into the mounting cavity 210 of the housing assembly 20.

[0113] Those skilled in the relevant technology can understand that the above assembly steps can be flexibly adjusted to achieve automated assembly, improve production efficiency, and reduce costs.

[0114] Please combine Figure 3 As shown, when the atomizing device 100 is assembled, the outer surfaces of the first housing part 21, the second housing part 52 and the liquid storage tank outer shell 31 are all smoothly transitioned to each other, making the atomizing device 100 look roughly circular to improve its aesthetics.
