Problems solved by technology

[0002] The traditional ultraviolet light source for sterilization and disinfection is a low-pressure mercury lamp. The Chinese patent document with the notification number CN2887310Y discloses a portable ultraviolet sterilizer. The light source is a low-pressure mercury lamp. Large size, high voltage requirements, fragility, and high heat generation limit the application of low-pressure mercury lamps in portable, small, battery-powered, temperature-sensitive, and outdoor applications.

Abstract

The invention belongs to the field of ultraviolet disinfection sterilization and discloses a portable ultraviolet (UV)-light-emitting diode (LED) sterilizer and a disinfection application thereof. An irradiation portion of the sterilizer comprises a battery compartment, a power switch, a working station indicator, a gravity sensor and at least one UV-LED luminous chip, the gravity sensor is used for preventing the sterilizer from upwards irradiating so as to protect human eyes from being burnt, the UV-LED luminous chip is arranged on a luminous surface of the irradiation portion, and the emission wavelength of the luminous chip is in a range from 250nm to 300nm, preferably 265nm to 280nm. The portable UV-LED sterilizer has the advantages of being small and exquisite in size, capable of low voltage direct current supply, low in heat productivity, impact resistant, convenient to carry about and particularly applicable to ultraviolet sterilization for articles of tableware, mobile phones, keyboards, elevator buttons, remote control, underclothes and the like.

Description

Technical field [0001] The invention belongs to the field of ultraviolet disinfection and sterilization, and particularly relates to a portable UV-LED disinfector and its disinfection use. Background technique [0002] The traditional ultraviolet light source for sterilization and disinfection is a low-pressure mercury lamp. The Chinese patent document with the publication number CN2887310Y discloses a portable ultraviolet sterilizer. Its light source is a low-pressure mercury lamp. The dominant wavelength of the low-pressure mercury lamp is usually 253.7nm. Large size, high voltage requirements, fragility, large heat generation and other reasons limit the application of low-pressure mercury lamps in portable, small, battery-powered, temperature-sensitive, and field applications. Summary of the invention [0003] Studies have found that some wavelengths of ultraviolet light can destroy the DNA structure of bacteria or viruses, and play a role in killing viruses and bacteria. The u...
