The present invention disclosed a super dry fog generator comprising a liquid-storage device, an atomization device, an air-blower and a dry separation device with an opening on the top wherein said dry separation device is above said liquid-storage device and connected with said liquid-storage device said atomization device is located at the exterior of said liquid-storage device the two ends of said atomization device are connected with said air-blower and the interior of said dry separation device, respectively said atomization device is connected with said liquid-storage device, and the liquid entering into the interior of said atomization device is blown into the interior of said dry separation device by said air-blower. The disinfection liquid entering into the atomization device from the liquid-storage device is atomized into small atomized liquid particles by the atomization device, and then the small atomized liquid particles are driven into the dry separation device by said air-blower. After being dried, the small atomized liquid particles are discharged to a space intended to be disinfected, then the disinfection is carried out. The small atomized liquid particles produced by the super dry fog generator of the present invention, whose size is small and much closer to the bacterial size, can be suspended in air for a long time so as to contact fully with the bacteria in air to achieve the purpose of sterilization, and they are convenient and safe with the less corrosion to the objects in the disinfection space.
