The anti-counterfeiting module 15 may be a PCB circuit board, which may be substantially in the shape of a circular plate. Two poles of the anti-counterfeiting module 15 are respectively communicated with the base 12 and the thimble 13, so that the anti-counterfeiting module 15 is powered. The anti-counterfeit module 15 may be disposed in the main body portion 121, a step 1211 for supporting the anti-counterfeit module 15 is formed on an inner wall surface of the main body portion 121, and at least a portion of a lower end surface of the anti-counterfeit module 15 is in contact with the step 1211. The anti-counterfeiting module 15 is longitudinally provided with a through hole 150, the thimble 13 is arranged in the through hole 150 in a penetrating manner, and the outer wall surface of the thimble 13 is in contact conduction with the hole wall of the through hole 150. Specifically, conductive layers may be formed on a portion of the lower end surface of the anti-counterfeit module 15 and the hole wall of the through hole 150 by spraying or electroplating, and the conductive layers are in contact with the base 12 and the thimble 13.

The anti-counterfeit module 15 is formed with a first through hole 151 for the first lead 171 to pass through and a second through hole 152 for the second lead 172 to pass through. The first lead 171 and the second lead 172 can be respectively connected to the first through hole 151 and the second through hole 152 by soldering. The first lead 171 is inserted through the first through hole 151, and then clamped between the outer wall surface of the insulating sleeve 14 and the inner wall surface of the abutting portion 122 by interference fit, and is in contact with the base 12. After penetrating out of the second through hole 152, the second pin 172 is clamped between the inner wall surface of the insulating sleeve 14 and the outer wall surface of the thimble 13 in an interference fit manner, and is in contact conduction with the thimble 13. The tail end of the second pin 172 can be bent and clamped between the upper end surface of the flange 131 and the lower end surface of the insulating sleeve 14, so as to increase the contact area between the second pin 172 and the thimble 13. The interference fit conduction mode has higher efficiency than welding, reduces welding procedures, ensures the reliability of connection due to interference fit, and improves the yield of products; in addition, the space is small if welding, the operation is not easy, and the welding yield is not easy to control.

The protective sleeve 16 is used to protect the anti-counterfeit module 15 from damage, contact by liquid matrix, and the like, and may be made of elastic material such as silica gel. The protective casing 16 may in some embodiments include a nest 161 at an upper, smaller outer diameter and a contact 162 at a lower, larger outer diameter. The nesting portion 161 can be tightly sleeved in the vent pipe 18, and the upper end of the thimble 13 can pass through the anti-counterfeiting module 15 and be embedded in the nesting portion 161. The lower end surface of the vent tube 18 can abut against the upper end surface of the contact portion 162, and the lower end surface of the contact portion 162 abuts against the upper end surface of the anti-counterfeit module 15, so that the protective sleeve 16 and the anti-counterfeit module 15 are clamped and fixed between the lower end surface of the vent tube 18 and the upper end surface of the step 1211. In other embodiments, protective sleeve 16 and security module 15 may be integrated, thereby eliminating the need for a separate protective sleeve 16; at this time, two contacts may be further disposed on the first lead 171 and the second lead 172 to be in contact with and electrically connected to the two contacts on the counterfeit prevention module 15, so that a welding process is not required.

The protective sheath 16 is provided with two electrode holes 160 for the first lead 171 and the second lead 172 to pass through. A thin wall 1601 may be formed in the electrode hole 160, and the thin wall 1601 divides the electrode hole 160 into two portions which are not communicated with each other. When the atomization assembly 17 is installed, the first pin 171 and the second pin 172 can pierce the thin wall 1601 and penetrate out of the electrode hole 160. The thin wall 1601 functions to enable the protective sleeve 16 to tightly wrap the first pin 171 and the second pin 172, and when the liquid matrix infiltrates into the electrode hole 160 from the atomizing assembly 17 side, the liquid matrix can remain on the upper side of the thin wall 1601 and cannot infiltrate into the anti-counterfeiting module 15, so that the anti-counterfeiting module 15 is damaged.

It can be understood that, in other embodiments, the atomizer 1 may not be provided with the anti-counterfeit module 15, at this time, only the first pin 171 and the second pin 172 of the atomizing assembly 17 need to be connected and conducted with the base 12 and the thimble 13, and the connection and conduction mode may be welding, riveting, crimping, and the like.

Fig. 5 to 7 show an atomizer 1 according to a second embodiment of the present invention, which is different from the first embodiment mainly in that in this embodiment, a first pin 171 is bent after passing through a first through hole 151, and a first contact portion 1711 of the first pin 171 at an end away from a heat-generating body is clamped between a counterfeit prevention module 15 and a main body portion 121 by interference fit. The first lead 171 is in contact with and electrically connected to the step 1211 and the inner circumferential surface of the body portion 121 via the first contact portion 1711, thereby electrically connecting the first lead 171 to the base 12. In addition, a first conductive layer 1531 may be further formed on a portion of the lower end surface of the anti-counterfeit module 15 and a portion of the outer peripheral surface correspondingly communicated with the portion of the lower end surface through spraying or electroplating, and the first lead 171 may be in contact conduction with the first conductive layer 1531 through the first contact portion 1711, so as to conduct the first lead 171 with the anti-counterfeit module 15, and the interference fit conduction manner may avoid a welding operation at the first through hole 151, thereby providing a processing efficiency and a product yield. In other embodiments, the first lead 171 can also be soldered in the first through hole 151, so as to be electrically connected to the anti-counterfeit module 15.

The second pin 172 is bent after penetrating through the second through hole 152, and the second contact portion 1721 of the second pin 172 at the end far away from the heating element is clamped between the hole wall of the through hole 150 and the outer wall surface of the thimble 13 in an interference fit manner. The second lead 172 is in contact with and conducted to the outer wall surface of the thimble 13 through the second contact portion 1721, so that the second lead 172 is conducted to the thimble 13. The second conductive layer 1532 may be formed on the hole wall of the through hole 150 of the anti-counterfeit module 15 by spraying or electroplating, and the second pin 172 may be in contact with the second conductive layer 1532 through the second contact portion 1721, so as to connect the second pin 172 to the anti-counterfeit module 15, thereby avoiding the welding operation at the second through hole 152 and improving the processing efficiency and the product yield. In other embodiments, the second lead 172 can also be soldered in the second through hole 152, so as to be electrically connected to the anti-counterfeit module 15.
