[0051] An aerosol-generating device generally includes a power supply structure, an atomizer and the like. The power supply structure supplies power to the atomizer. The atomizer generally includes a liquid storage shell and an atomizing core. A liquid storage cavity is arranged in the liquid storage shell to store an aerosol-generating substrate. The atomizing core is installed in the liquid storage shell. The aerosol-generating substrate in the liquid storage cavity flows to the atomizing core. The atomizing core is powered to heat the aerosol-generating substrate and atomize the aerosol-generating substrate to generate an aerosol for a user to use.

[0052] With use of the atomizer, the aerosol-generating substrate in the liquid storage cavity will gradually decrease or even be used up. At this time, the atomizer needs to be used again, and the aerosol-generating substrate needs to be added to the liquid storage cavity. In order to facilitate the addition of the aerosol-generating substrate to the liquid storage cavity, an injection hole is generally arranged on the side of the liquid storage shell. In order to prevent the aerosol-generating substrate in the liquid storage shell from leaking from the injection hole, a plug is generally arranged to cooperate with the injection hole after the addition is completed. A connecting portion is generally arranged on the plug. The connecting portion is connected to the liquid storage cavity through a clamping protrusion or a buckle. After the plug is pulled out, the plug is still supported on the liquid storage shell by the connecting portion. Therefore, after the injection, the plug can be sealed in the injection hole in a direction, so as to facilitate use. However, after being pulled out and inserted for many times, the clamping of the connecting portion and the liquid storage shell is prone to loosening, and the plug is prone to falling off.

[0053] Based on the above considerations, in order to improve the problem of easy falling after multiple plug-in use of the blockage on the liquid storage shell in the related art, the embodiment of the present application provides an atomizer, by setting a liquid injection hole on the liquid storage shell, so as to inject the aerosol generating substrate into the liquid injection cavity, by setting the hole plug part, so as to block the liquid injection hole; the support part is connected on one side of the hole plug part, and the blocking piece is installed on the liquid storage shell, so that the blocking piece cooperates with the liquid storage shell to limit the support part, so as to prevent the risk of falling of the support part, and the support part is connected with the hole plug part, so as to support the hole plug part through the support part, and then the hole plug part can be prevented from falling well.
