[0031] See Figure 1-5 As shown, the embodiment of the present invention provides a power supply module, which includes: a first shell 10, a second shell 20, a circuit board 50, a first electrode 40, a protective member 60 and a first limit portion 13; wherein the first shell 10 is provided with a first through hole 15; the second shell 20 is detachably connected to the first shell 10 to form a receiving cavity 30; the circuit board 50 is received in the receiving cavity 30; the first electrode 40 is connected to the circuit board 50 and passes through the first through hole 15, and the first electrode 40 is spaced from the hole wall of the first through hole 15. A first gap 16 is formed; the protective member 60 is accommodated in the accommodating cavity 30, the protective member 60 is sleeved on the first electrode 40, and a portion of the first electrode 40 extends out of the protective member 60; the first limiting portion 13 is provided on the first shell 10 and extends toward the accommodating cavity 30, the first limiting portion 13 and the circuit board 50 are constructed to form an accommodating space 31, the protective member 60 is located in the accommodating space 31, the protective member 60 is in contact with the circuit board 50, and the protective member 60 and the first limiting portion 13 are separated to form a second gap 32, and the first gap 16 is larger than the second gap 32.

[0032] Specifically, when the first shell 10 and the second shell 20 are assembled, if the position of the first electrode 40 deviates from its designed position, the first electrode 40 is likely to hit the hole wall of the first through hole 15. Since the first gap 16 is larger than the second gap 32, the protective member 60 abuts against the first limiting portion 13 to limit the first electrode 40 and prevent the first electrode 40 from hitting the hole wall of the first through hole 15.

[0033] See Figure 2 and Figure 3As shown, the first electrode 40 includes a connecting portion 43, a mounting portion 42, and an extension portion 41. The connecting portion 43 is connected to the circuit board 50; the mounting portion 42 is connected to the connecting portion 43 and is disposed through the protective member 60; and the extension portion 41 is connected to the mounting portion 42 and is disposed through the first through hole 15. The protective member 60 defines a second through hole 61, and the mounting portion 42 is disposed through the second through hole 61.

[0034] See Figure 2 、 Figure 3 as well as Figure 9 As shown, the mounting portion 42 includes a first sub-mounting portion 421 and a second sub-mounting portion 422. The first sub-mounting portion 421 is connected to the protruding portion 41, and the second sub-mounting portion 422 is connected to the connecting portion 43. The diameter of the first sub-mounting portion 421 is smaller than the diameter of the second sub-mounting portion 422. A first positioning step 423 is formed between the first sub-mounting portion 421 and the second sub-mounting portion 422.

[0035] The second through hole 61 includes a third sub-hole 611 and a fourth sub-hole 612. The aperture of the third sub-hole 611 is smaller than the aperture of the fourth sub-hole 612.

The first sub-mounting portion 421 is accommodated in the third sub-hole 611, and the second sub-mounting portion 422 is accommodated in the fourth sub-hole 612. The first positioning step 423 abuts against the second positioning step 613, thereby fixing the relative position of the protective member 60 and the first electrode 40.

[0036] See Figure 2 and Figure 3 As shown, the first through hole 15 includes a first guide hole 153, the first guide hole 153 is close to the accommodating cavity 30, and the direction of the first shell 10 toward the second shell 20 is configured as a first direction. The aperture of the first guide hole 153 gradually increases along the first direction. When the first shell 10 is assembled to the second shell 20, the first guide hole 153 guides the first electrode 40 so that the first electrode 40 can smoothly enter the first through hole 15.

[0037] The first direction is Figure 2 and Figure 3 As shown by L1 in FIG, the first direction is the direction from the first shell 10 to the second shell 20.

The second sub-hole 152 is close to the accommodating cavity 30. The aperture of the first sub-hole 151 is smaller than the aperture of the second sub-hole 152. The diameter of the protruding portion 41 is smaller than the diameter of the first sub-mounting portion 421. The aperture of the second guide hole 154 gradually increases along the first direction. When the first shell 10 is assembled to the second shell 20, the second guide hole 154 guides the protruding portion 41 so that the protruding portion 41 can smoothly enter the first sub-hole 151.

[0039] A portion of the first sub-mounting portion 421 is received in the second sub-hole 152, and the extending portion 41 extends out of the first shell 10 from the first sub-hole 151. The gap between the extending portion 41 and the hole wall of the first sub-hole 151 is larger than the gap between the first sub-mounting portion 421 and the hole wall of the second sub-hole 152 to prevent the extending portion 41 from being stuck when extending.

The second sub-limiting portion 132 and the third sub-limiting portion 133 are separated to form a gap. The second sub-limiting portion 132 is provided with a first limiting groove 1321, and the third sub-limiting portion 133 is provided with a second limiting groove 1331. The end of the circuit board 50 away from the second shell 20 is simultaneously embedded in the first limiting groove 1321 and the second limiting groove 1331; the second shell 20 is provided with a third limiting groove 231 and a fourth limiting groove 232. The end of the circuit board 50 away from the first shell 10 is simultaneously embedded in the third limiting groove 231 and the fourth limiting groove 232 to fix the circuit board 50.

[0041] Specifically, the first housing 10 includes a first cover 11 and a first peripheral wall 12. The first peripheral wall 12 is disposed around the first cover 11. The first through hole 15, the first sub-limiting portion 131, the second sub-limiting portion 132, and the third sub-limiting portion 133 are all disposed on the first cover 11. The first sub-limiting portion 131, the second sub-limiting portion 132, and the third sub-limiting portion 133 are protruding in the first direction, and the first sub-limiting portion 131, the second sub-limiting portion 132, and the third sub-limiting portion 133 are all located within the receiving cavity 30.

Specifically, the first peripheral wall 12 is provided with the buckle 121, and the second peripheral wall 22 is provided with the slot 221.

[0043] See Figure 10 As shown, a second guide portion 25 is provided on the side of the second limiting portion 23 and the third limiting portion 24 away from the circuit board 50. The second guide portion 25 has a second guide slope 251. The distance between the second guide portion 25 and the circuit board 50 gradually decreases along the first direction to guide the circuit board 50 to embed into the third limiting groove 231 and the fourth limiting groove 232.

[0044] See Figure 4 and Figure 5 As shown, a reinforcing rib 134 is provided on one side of the first limiting portion 13 near the protective member 60. The reinforcing rib 134 is used to reduce the gap between the protective member 60 and the first limiting portion 13, further preventing the first electrode 40 from contacting the wall of the first through-hole 15. Because the protective member 60 needs to cooperate with the first limiting portion 13 during use, the protective member 60 will squeeze the first limiting portion 13.

The first guide portion 14 has a first guide slope 141. The distance between the first guide portion 14 and the protective member 60 gradually increases along the first direction to guide the protective member 60. At the same time, the first guide portion 14 strengthens the strength of the first limiting portion 13, thereby increasing the service life of the first limiting portion 13.

[0047] An embodiment of the present invention also provides an atomization device, including an atomization module and the above-mentioned power module; the atomization module and the power module are detachably connected, and the atomization module includes a second electrode, which abuts against the first electrode 40 to electrically connect the atomization module and the power module.

[0048] The atomization module in the embodiment of the present invention is conventional technology in the field, so its layout and connection are not described in detail here.

[0049] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0051] The above are merely preferred embodiments of the present application and are not intended to limit the present application.
