The change-over pipe joint of the air passage pipe orifice of the humidification tank is set to be an adjusting valve, a change-over inner pipe and a change-over joint; when liquid is to be added through the air passage pipe orifice in misoperation, the switching inner pipe is synchronously driven to close the regulating valve in the process of removing the adapter, so that the regulating valve is closed, liquid is effectively prevented from being added at the air passage pipe orifice due to misoperation, and safety accidents are avoided; and, when will again when the adapter is installed, the adapter drives in step the switching inner tube will the regulating valve is opened, and then has ensured simultaneously the normal operating of humidifying jar, and can adjust the flow of giving vent to anger.

It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
