TH17419U - Disinfectant for objects attached to a stationary structure. - Google Patents

Abstract

This invention relates to a sterilizing device for stationary or fixed public equipment, such as doorknobs or handrails, elevator control buttons, or restroom fixtures, etc., which relies on the sterilization of contaminants on the equipment with ultraviolet light or ozone gas within a closed system and can be moved to the location where the equipment is installed, making it convenient and safe for the operator to use. This invention provides a sterilizing device (1) for objects (2) fixed to a stationary structure (3), consisting of a sterilization chamber (4) with an opening (5) as the only area open to the inside and outside of the chamber, an ultraviolet light or ozone gas source (6), a power source (7), a control device (8), an operation display device (9), a leak detection device (10), a sealing device (11), and a movable structure (12) in which the sterilization chamber (4) fits the object (2) onto the structure (3) through the opening (5) in such a way that the edge of the opening (5) contacts the surface of the structure (3). The light source The ultraviolet or ozone source (6) emits ultraviolet light or ozone gas into the sterilization chamber (1) and impacts the object (2). A leak detection device (10) is installed at the edge of the opening (5) and detects the air gap along the contact between the edge of the opening (5) and the surface of the structure (3). A sealing device (11) is installed at the edge of the opening (3) and seals the air gap along the contact between the edge of the opening (R) and the surface of the structure (3). A movable structure (12) moves the sterilization chamber (4), the ultraviolet or ozone source (6), the control device (8), the display device (9), the leak detection device (10), and the sealing device (11) to the location where the object (2) is installed and the ultraviolet or ozone source (6) is deactivated when the leak detection device (11) detects the air gap along the contact between the edge of the opening (S) and the surface of the structure (3).
