For this purpose, ozone generators are installed on the main bodies or suctioning heads of vacuum cleaners in the related art. The ozone generated from the ozone generators is discharged through a vacuum cavity by means of the vacuuming force.
- Accordingly, in such devices relying on this structure employing vacuuming force to discharge ozone into the vacuum cavity, the ozone cannot effectively reach the carpet, so that effective removal of mites and germs from the carpet is not possible.
- Also, to increase suctioning power, conventional vacuum cleaners use large capacity-blowers, resulting in increased noise and power consumption as well as increased discharge of fine dust particles.
- Accordingly, the present invention is directed to a vacuum cleaner that substantially obviates one or more problems due to limitations and disadvantages of the related art.
- An object of the present invention is to provide a vacuum cleaner that has a structure in which air circulates back to a vacuum cavity of a vacuum head by air suctioning and discharging forces generated by a blower motor, while at the same time using the principle of a venturi to cause ozone to infiltrate a surface that is being cleaned for a sterilizing and disinfecting effect.
