US 12,667,633 B2 · Aqueous ozone floor disinfection system

Abstract

The present invention relates to an aqueous ozone floor disinfection system. A floor cleaning machine traverses a floor surface entering a pre-hygienic zone prior to cleaning, cleaning within a midst-hygienic zone for a cleaning period, and moving away from the midst-hygienic zone creating a post-hygienic zone. An aqueous ozone generator receives water and generates an ozonated concentrate liquid. A post-hygienic mixer ratiometrically blends the ozonated concentrate liquid and water to form a post-hygienic ozone disinfection solution having a predetermined post-hygienic ozone treatment concentration. A post-hygienic nozzle spray of the post-hygienic ozone disinfection solution onto the post-hygienic zone portion of the floor surface for at least the post-hygienic treatment time absent agitation or removal by the floor cleaning machine improving disinfection of the floor surface. The service life of the aqueous ozone generator can be tracked and the disinfected floor surface can be GPS geofenced.

Dependent claims

An aqueous ozone floor disinfection system comprising;

a cleaning mechanism that is capable of traversing a floor surface and cleaning the floor surface;
an aqueous ozone generator that receives water and generates an ozonated concentrate liquid from the water;
a mixer that receives and ratiometrically blends a portion of the ozonated concentrate liquid with water to form an ozone disinfection solution at a desired ozone concentration level, the mixer changes the ozone concentration levels of the ozone disinfection solution based on speed that the cleaning mechanism traverses the floor;
and
a nozzle that sprays the ozone disinfection solution onto the floor surface after the floor surface has been cleaned by the cleaning mechanism.
