Description

Portable deep ultraviolet ray disinfection equipment

Technical Field

The utility model relates to an ultraviolet ray disinfection technical field, concretely relates to portable dark ultraviolet ray disinfection equipment.

Background

The ultraviolet sterilization and disinfection effect is discovered at the end of the nineteenth century and is a serious scientific conclusion which has been verified for hundreds of years. Ultraviolet with the wavelength range of 250-280nm has broad-spectrum sterilization effect on bacteria and viruses, and particularly, the ultraviolet with the wavelength range of 250-280nm has effective sterilization effect only on C-band ultraviolet, and the influence of B-band ultraviolet and A-band ultraviolet on microorganisms is only one thousand times of that of C-band ultraviolet, so that the ultraviolet-sterilization disinfection composite material has no practical sterilization and disinfection significance. The C-band ultraviolet ray destroys the molecular structure of genetic material DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) of microbial organism cells (including bacteria, fungi, algae, protozoa and the like) and acellular bodies (viruses), thereby achieving the effects of sterilization and disinfection. The main inactivation mechanism is that the substance nucleic acid (DNA and RNA) has strong absorption capacity (the absorption peak value is 265nm) to the ultraviolet ray of the C wave band, and the energy carried by the C wave band ultraviolet photon can effectively reach the genetic material and destroy the chain structure of the genetic material, so that the replication of the genetic material is stopped and destroyed, and finally, the bacteria and the virus cannot replicate (propagate), thereby achieving the disinfection effect. In addition, ultraviolet rays also have the function of breaking hydrogen bonds in protein molecules of microbial cells, so that the protein is denatured, and the cell body loses the metabolic capability and dies.

Deep ultraviolet LEDs are significantly different in materials, processes and applications compared to common visible light LEDs (for illumination). The group III nitride, one of the most advanced in the semiconductor material field, is the most ideal and spectrally-fullest all-solid-state uv-luminescent material currently known. Group III nitrides emit light with increasing aluminum Al composition in a stepwise shift from visible to Ultraviolet (UV) wavelengths. Pure aluminum nitride (AlN, 100 percent of aluminum component) has the luminescence wavelength of 203nm, and the AlGaN luminescence wavelength can cover the spectrum of 203-400nm, which covers the ultraviolet rays in three bands of UVA, UVB and UVC. Ultraviolet sterilization is physical sterilization, is basically not influenced by environmental factors such as temperature, humidity and the like compared with chemical sterilization, has broad-spectrum sterilization capability, has more effective and faster inactivation capability on bacteria, viruses, fungi, protozoa and the like, does not have any harmful residues, toxic or side effect and drug resistance problem, and has great significance on reducing abuse of antibiotics and improving the environment.

Comparison of deep ultraviolet LEDs with conventional ultraviolet light sources: until the breakthrough of group III nitride ultraviolet light emission was achieved, the ultraviolet gain was mainly due to high voltage arc discharge and mercury vapor ionization. The method has the defects of large volume, high power consumption, high voltage requirement, poor safety, harm to human and environment (mercury pollution) and poor spectrum adjustability, wherein the mercury pollution is regarded as a permanent pollutant which is most harmful by the world, China has approved to be officially added into the United nations environmental protection agency 'Water-good-for-mercury convention' in 2016, and aims to comprehensively limit the production and import and export of mercury and mercury addition products. The development of all-solid-state semiconductor-based ultraviolet LEDs will overcome these disadvantages, cover and broaden the ultraviolet application range, and have a tremendous impact on the environment and national economy.

The differences between the deep ultraviolet LED and the conventional low-pressure mercury lamp are compared as follows: (1) environmental protection and safety: the low-pressure mercury lamp contains heavy metal, the ultraviolet LED does not contain heavy metal, and the RoHS standard is compounded; (2) spectral characteristics: low pressure mercury lamps, ultraviolet LEDs; (3) output light intensity per unit area: the low-pressure mercury lamp is 1mw/cm²Grade, ultraviolet LED 1000mw/cm²A rank; (4) response frequency: the low-voltage mercury lamp needs stable time, cannot be switched on and off at high frequency, the ultraviolet LED responds in time, and the switching frequency is 10⁸Hz; (5) the external dimension is as follows: the lamp tube of the low-voltage mercury lamp has large volume, needs a ballast, has small ultraviolet LED volume, and the chip volume is 1 multiplied by 0.5mm³(ii) a (6) Working current: the low-voltage mercury lamp is generally larger than 0.2 ampere, the ultraviolet LED is 0.02 ampere, and the low-voltage mercury lamp is adjustable; (7) working voltage: alternating current of the low-pressure mercury lamp is 110-; (8) output regulation: the low-pressure mercury lamp is not adjustable, and the ultraviolet LED is adjustable; (9) the use environment is as follows: the working environment temperature of the low-pressure mercury lamp is 25 ℃, and the working environment temperature of the ultraviolet LED is-20 ℃ to 55 ℃; (10) reliability: the low-pressure mercury lamp vacuum glass pipe fitting is easy to damage, and the ultraviolet LED is a solid-state light source, so that the LED is firm and reliable.

Based on this, it is especially necessary to design a new portable deep ultraviolet disinfection device.
