By adopting the above scheme, when the atomizer is started to work, the aerosol-forming substrate in the liquid storage cavity 11 of the liquid storage component 1 enters the atomizing cavity 75 through the liquid inlet 721, the atomizing core 73 is driven by the power supply device to heat and atomize the aerosol-forming substrate entering the atomizing cavity 75, air entering the atomizing cavity 75 from the air inlet 141 on the base 14 is rapidly mixed with the atomized aerosol-forming substrate to form aerosol smoke, the aerosol smoke is guided to the smoke outlet 151 through the smoke guide channel 741 along with negative pressure airflow formed when a user sucks, and smoke in the smoke outlet 151 enters the cigarette holder 9 through the smoke guide port 31 to be sucked by the user. The pouring outlet 12 is provided in the upper cover 15, the pouring lid having the locking portion 41 is movably provided in the upper cover 15 along a predetermined path, and a guide groove 43 and a lock groove 42 are provided in the predetermined path. When in use, the liquid injection cover can be moved to the first position along the preset path, and the liquid injection cover can be utilized to seal and cover the liquid injection port 12. And when annotating the liquid, only need along predetermineeing the route and will annotate liquid lid and remove the sealed closing cap effect of annotating liquid lid to annotating liquid mouth 12, annotate liquid mouth 12 and be exposed, user alright conveniently through annotating liquid mouth 12 on stock solution spare 1 upper portion add gas colloidal sol to stock solution chamber 11 and form the matrix.

Referring to fig. 1, 4 and 13, in some embodiments, the air adjusting ring 8 is rotatably sleeved on the outer circumferential surface of the base 14, and the air adjusting ring 8 is provided with an air adjusting hole 81 aligned and communicated with the air inlet hole 141 or staggered with the air inlet hole 141, so that the air adjusting ring 8 can be rotated along the circumferential direction of the base 14 to adjust the aligned and communicated area of the air adjusting hole 81 and the air inlet hole 141, so as to adjust the flow rate of the external air entering the atomizing chamber 75.

When the atomizer provided by the embodiment of the utility model is in a non-liquid injection state, the liquid injection cover only needs to be moved from the second position to the first position along the preset path, the locking part 41 can be moved into the locking groove 42 along with the liquid injection cover, then the liquid injection cover is rotated relative to the liquid storage part 1, the liquid injection cover drives the convex ring to rotate 90 degrees in the flaring groove 421 of the locking groove 42, the stopping part 424 of the locking groove 42 stops the convex ring 412, and the liquid injection cover can be locked at the first position on the liquid storage part 1, so that a child cannot easily open the liquid injection port 12 through simple stirring action. When the atomizer provided by the embodiment of the utility model needs to inject liquid, the liquid injection cover only needs to be rotated relative to the liquid storage component 1, the liquid injection cover drives the convex ring 412 to rotate 90 degrees in the flared groove 421 of the locking groove 42, the stopping part 424 of the locking groove 42 releases the stopping of the convex ring 412, and the locking of the liquid injection cover can be released. After the locking structure 4 releases the locking of the liquid injection cover, the liquid injection cover is shifted from the first position to the second position along the preset path, so that the liquid injection port 12 is exposed, and then a user can add gas sol to the liquid storage cavity 11 through the liquid injection port 12 to form matrix. Annotate the liquid back that finishes, will annotate the liquid lid again and will be annotated the liquid lid by the second position along presetting route towards the primary importance and stir, will annotate the liquid lid lock in the primary importance through locking structure 4, children just are difficult to open through simple stirring action and annotate liquid mouth 12 to avoid children to contact and eat aerosol formation matrix by mistake even, improve the security of atomizer.

The utility model also provides an aerosol generating device comprising an atomiser as provided in any of the embodiments above, the atomiser being actuated by electrical power from a power supply means (not shown) of the aerosol generating device. The atomizer provided in any one of the above embodiments has all the technical features, so that the atomizer has the same technical effects as the atomizer.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
