Title:
ULTRAVIOLET STERILIZATION AND DISINFECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/222481
Kind Code:
A1
Abstract:
An ultraviolet sterilization and disinfection apparatus, comprising: a lamp body (301) and an optical filter. The lamp body (301) and the optical filter are both cylindrical. The optical filter is coaxially sleeved on the outer side of the lamp body (301), and an outer side wall of the optical filter is circumferentially 360° fully plated with an optical filter film, such that light of a first wavelength emitted by the lamp body (301) passes through, and associated light of a second wavelength emitted by the lamp body (301) is isolated. The two ends of the lamp body (301) and the optical filter are fixed by means of a lamp holder (303). In this way, 360° and wide range output of UV light of the first wavelength that is safe for human body is achieved, the associated light of the second wavelength harmful to the human body is effectively reduced, the space operation range of the ultraviolet sterilization and disinfection apparatus is expanded, the loss of light of the first wavelength is reduced, and the use efficiency of the ultraviolet sterilization and disinfection apparatus is greatly improved.
