Portable LED ultraviolet disinfection and sterilization device

Abstract

The invention discloses a portable LED ultraviolet disinfection and sterilization device, and relates to the technical field of sterilization / disinfection. The device comprises a holding body, a handguard and a functional body, the hand guard is arranged between the holding body and the functional body; a power supply device is arranged in the holding body, the functional body is a carrier of anLED ultraviolet lamp, and the hand guard is a transition body between the holding body and the functional body, protects the hand of a user from being irradiated by ultraviolet light, serves as a ruler, and positions a disinfected and sterilized object and the optimal position of the functional body. The device is simple in structure, diverse in device mode, flexible in switching and reliable in operation; a user can refer to the ruler to select the effective distance (the surface of the functional body and the surface of the disinfected and sterilized object), effective sterilization and disinfection are enhanced, and therefore the effectiveness of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sterilization / sterilization, in particular to a portable LED ultraviolet disinfection and sterilization device. Background technique [0002] LEDs with a light emitting wavelength of 240-300nm have disinfection and bactericidal effects. Mainly because of its short wavelength and high energy, it is easy to destroy the ribonucleic acid of bacteria, and make bacteria lose their vigor and reproductive ability. Ultraviolet light has become an important physical sterilization method. With the improvement of people's quality of life, enough attention has been paid to the disinfection and sterilization of daily necessities. However, the traditional industrial-grade disinfection and sterilization equipment using mercury lamps as ultraviolet light sources is not conducive to small-scale use due to its large size, high power consumption, and complicated operation. . Furthermore, the portable LED ultraviolet disinf...

Problems solved by technology

[0003] At present, there are many portable LED ultraviolet disinfection and sterilization devices, but most of them are based on one ("point") light source. The disinfection and sterilization area is too small to effectively kill flat-like items, which increases the use time of disinfection and sterilization, and needs to be carried out. Reciprocating multiple killings; or multiple ("line") light sources are arranged in one line, but the irradiation range of the light bar is too large, resulting in most of the excess ultraviolet rays being easily irradiated elsewhere, which increases the power consumption of the device, which is not conducive to the protection of the device. Energy saving; easy to make users vulnerable to ultraviolet radiation, which also has a serious impact on health; the above structure limits the scope of use of LED ultraviolet disinfection and sterilization devices, and cannot eliminate and sterilize tubular cavities (such as cups) ,

[0004] In summary, in order to solve the problem that the disinfecting area is too small when the point light source is configured in the prior art, the irradiation area is too large when the line light source is configured, and at the same time, the tubular cavity cannot be eliminated and sterilized
