In some embodiments, as shown in fig. 7 and 8, the electrode lead 221 further includes a bent portion 2212 bent from the exposed portion 2211, the bent portion 2212 being bent and extended toward the heating element 22 such that an end portion of the electrode lead 221 exposed to the atomizer 100 is not electrically connected to the power supply means, that is, an end portion 22121 of the bent portion 2212 is not electrically connected to the power supply means, and the end portion 22121 is not easily observed by a user through the bending of the bent portion 2212 to enhance the aesthetic appearance of the atomizer 100. In addition, by bending the bending portion 2212, the end portion 22121 is not easily hooked during the use of the atomizer 100, so that the exposed portion of the electrode lead 221 is prevented from being turned over due to the hooking of the end portion 22121.

In some embodiments, as shown in fig. 9, the base 30 is formed with an electrode groove 341, and the electrode groove 341 is used to receive the electrode lead 221, so as to position the electrode lead 221 in the electrode groove 341, avoiding easy displacement of the electrode lead 221.

Preferably, the clamping space 221d is designed in a U-shape to better enable the base 30 to provide support for the electrode lead 221.

In some embodiments, since a portion of the electrode lead 221 is exposed to the atomizer 100, the exposed portion of the electrode lead 221 is easily corroded or worn during use, to reduce the probability of corrosion or wear of the exposed portion of the electrode lead 221, thereby increasing the service life of the electrode lead 221, the atomizer 100 further includes a shield (not shown) that is removably attachable to the base 30, and that is attachable to the base 30 when the atomizer 100 is not in use, and that shields the electrode lead 221; when it is desired to use the nebulizer 100, the shield is removed from the base 30, and the electrode lead 221 is exposed for electrical connection to the power supply mechanism.
