A Portable Deep Ultraviolet Sterilizer

Abstract

The invention discloses a portable deep-ultraviolet sterilizing instrument, comprising a distance measuring device for detecting whether the distance between the object to be sterilized and the sterilizing lamp of the sterilizing instrument is within a preset distance range; a human body recognition device for recognizing a human face Whether to enter the irradiated area of ​​the disinfection lamp of the sterilizer; the gravity sensing device is used to detect whether the sterilization lamp of the sterilizer is perpendicular to the object to be sterilized; the diameter of the irradiation area of ​​the blue visible light is the same as the The diameter of the irradiation area of ​​the disinfection lamp is equal; when the control circuit board receives that the face does not enter the irradiation area of ​​the disinfection lamp of the disinfection instrument, the distance between the object to be disinfected and the disinfection lamp of the disinfection instrument is within the preset distance range And when the disinfection lamp of the disinfection instrument is perpendicular to the information of the object to be disinfected, the control circuit board controls the disinfection lamp to disinfect the object to be disinfected. The invention can protect people's faces from being hurt; the distance measuring device is also used to make the irradiation distance of the light emitted by the disinfection lamp accurate, and the disinfection effect is good.

Description

technical field [0001] The invention belongs to the technical field of virus disinfecting, and in particular relates to a portable deep ultraviolet disinfecting instrument, especially a portable deep ultraviolet killing instrument for disinfecting novel coronaviruses. Background technique [0002] Since December 2019, multiple cases of pneumonia patients infected with the new coronavirus have been found in Wuhan City, Hubei Province. With the spread of the epidemic, such cases have also been found in other parts of my country and abroad. As an acute respiratory infectious disease, the disease is a Class B infectious disease. [0003] According to the "Guidelines for Transmission and Prevention of Novel Coronavirus" drawn up by the National Health and Construction Commission, the transmission routes of the virus mainly include: direct or aerosol transmission: inhalation of droplets sprayed by infected people when they cough, sneeze or talk, or the air formed by droplets Sol ...

AI Technical Summary

Problems solved by technology

[0018] (1) Multi-band, but consumes a lot of power, and excess bands generate heat;

[0019] (2) The service life is short, with an average life span of 1000 hours;

[0021] (4) Harmful gas-ozone will be produced in the working state;

[0022] (5) The lamp tube contains mercury, and the discarded lamp tube needs special treatment;

[0023] (6) Use high voltage excitation (up to 5000V), which is very dangerous

[0027] 1. Large volume, inconvenient to carry;

[0028] 2. When the human body is accidentally irradiated by the deep ultraviolet light emitted by the deep ultraviolet LED, it will cause harm to the human body;

[0029] 3. In addition, because the object to be sterilized is placed within a suitable distance from the deep ultraviolet LED, the best sterilization effect can be achieved, and the disinfection instrument in the prior art cannot judge the object to be sterilized and the deep ultraviolet light. The distance of the LED can only be judged by the experience of the user, so the objects that cannot be accurately sterilized will be placed within the optimal irradiation distance of the deep ultraviolet LED, so the sterilization effect is not good and the objects cannot be sterilized to the maximum extent.
