A process and apparatus for disinfection of spaces using a disinfecting liquid droplet spray atomization are described, in which an electric fan 107 is used to dispense the atomization from an atomization chamber 104 via venture outlets 106 into the space to be disinfected. The operation of the electric fan 107 is modulated in a cycle having a first phase in which the fan is operated at full speed and a second phase at which the fan is operated at a randomly selected speed to vary the rate of dispensing into the space in order to improve the dispersal of the atomized droplets in the space and hence the efficacy of disinfection.

A liquid introducing device transfers a fixed amount of liquid medicine into atomized particles. The liquid medicine is connected to the liquid introducing device which allows the users to quickly replace the bottles and avoid cross infection between different medicines.
