Abstract

The invention relates to an ultraviolet light source sterilization device. The ultraviolet light source sterilization device comprises a support (1), a supporting rod (2), a supporting seat (3) and alight source sterilization structure (4), an installation end of the supporting rod (2) is connected with the support (1), a free end of the supporting rod (2) is connected with the supporting seat (3), and the supporting rod (2) is supported on the support (1) through the installation end in a reciprocating mode, the supporting seat (3) can rotate by using the free end as an axis, and the light source sterilization structure (4) is supported on the supporting seat (3) in the mode that an irradiation angle can be adjusted. The ultraviolet light source sterilization device has a distance measuring function, can adjust sterilization time in real time according to different sterilization distances, and realizes uniform, accurate and efficient sterilization; and by adopting an ultraviolet truncated cone-shaped groove array design, an ultraviolet sterilization lamp has very high directionality, and meanwhile, an attenuation of ultraviolet power can be reduced. The ultraviolet light source sterilization device can realize 360-degree dead-corner-free sterilization in an independent space.

Description

technical field [0001] The invention relates to the technical field of sterilization devices, in particular to an ultraviolet light source sterilization device and a sterilization method. Background technique [0002] Bacteria are ubiquitous in people's living environment, and most of these bacteria are harmful to health, such as Escherichia coli, Clostridium tetani, etc. At the same time, viruses are always around us, threatening our human health. Because ultraviolet rays can destroy the molecular bonds of bacterial deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), destroy the original bacterial colony and prevent the reproduction of bacteria, so ultraviolet rays can kill bacteria and viruses. Ultraviolet disinfection technology uses high-intensity ultraviolet radiation to directly kill various bacteria, viruses, parasites and other microorganisms. Ultraviolet sterilization has broad-spectrum and high efficiency, and has the ability to kill most bacteria and viruses...

AI Technical Summary

Problems solved by technology

[0005] 1. The directionality of the existing ultraviolet rays is very poor, and it is very difficult to concentrate the energy of sterilization, and it is difficult to achieve efficient sterilization

[0006] 2. There is an exponential attenuation law in the propagation of ultraviolet rays in air and water, which will inevitably lead to a significant decrease in the power of ultraviolet rays after long-distance transmission, and a significant decrease in the sterilization and disinfection efficiency, and may even fail to achieve the effect of sterilization and disinfection

[0007] 3. There is no way to measure the sterilization distance, and it is impossible to perceive and calculate the loss of ultraviolet energy at different distances

[0008] 4. Unable to sterilize large area and multi-angle

[0009] 5. Long-distance ultraviolet rays cannot be oriented and focused, resulting in low sterilization efficiency;

[0010] 6. Hand-held sterilization equipment requires personnel assistance, and it is easy to cause omissions and incomplete sterilization;

[0011] 7. The existing sterilization equipment cannot detect the sterilization distance, so the required sterilization time cannot be calculated;

[0012] 8. The dose of irradiation reaching the sterilization surface is uneven, resulting in uneven sterilization rate

[0013] Due to the above shortcomings of long-distance sterilization and disinfection, the long-distance sterilization is very inefficient, so it is particularly important to solve the above shortcomings for the application and expansion of long-distance ultraviolet sterilization
