Large-range sterilization device

Technical Field

The utility model belongs to the technical field of sterilization devices, and particularly relates to a large-range sterilization device.

Background

Ultraviolet radiation is electromagnetic radiation having a wavelength shorter than visible light but longer than the X-ray, the ultraviolet wavelength ranging from 10 nm to 400 nm, and energy ranging from 3 electron volts (eV) to 124 electron volts (eV). Its name is that the electromagnetic wave frequency in the spectrum is higher than the purple visible to the naked eye, also known as ultraviolet light.

Ultraviolet rays are classified into ultraviolet rays a, ultraviolet rays B, ultraviolet rays C, and the like according to wavelength. The ultraviolet C, abbreviated as UVC, also called deep ultraviolet, generally refers to ultraviolet light wave with wavelength of 100 nm to 280 nm, and its energy is between 12.4eV and 4.43 eV. Scientific researches show that the deep ultraviolet has extremely strong killing effect on microorganisms such as bacteria, viruses and the like.

UVC LED disinfects has outstanding advantages: the irradiation intensity is high, the light intensity of unit area is more than 1000 times higher than that of a mercury lamp, and the sterilization efficiency is high; the detergent is nontoxic, residue-free and odor-free when being used, and has no influence on the environment completely; the spectral line is concentrated, no clutter exists, and no ozone is generated; does not contain toxic elements such as mercury and the like, meets the international water guarantee, and is safe and environment-friendly; long service life, generally 10000-20000 hours, and high reliability.

Because of these outstanding advantages of the UVC LED, the UVC LED is currently being widely used in various sterilization and disinfection scenes, such as portable, household, and commercial applications.

The deep ultraviolet LED can effectively kill various bacteria and viruses, but the deep ultraviolet LED is a point light source, the packaged deep ultraviolet LED has a fixed luminous angle, and only microorganisms in the coverage range of the luminous angle can be irradiated and killed, so that the sterilization area of the fixedly installed deep ultraviolet LED sterilization device is limited.

Patent document CN201110368006.0 discloses a removable type sterilization device, which is a flat structure and has a substrate and a transparent plate inside, wherein a plurality of uv leds are installed between the substrate and the transparent plate, and when the device is placed inside an electrical appliance such as a refrigerator, the uv light emitted from the uv leds can penetrate through the transparent plate to irradiate the articles placed thereon for sterilization.

The device needs to increase the number of ultraviolet LEDs for realizing comprehensive disinfection, otherwise, if the ultraviolet LEDs are covered by articles placed above the device, the disinfection effect is greatly influenced; but the cost is greatly increased by adding the ultraviolet LED; in addition, the ultraviolet LED has large heat productivity, and can influence the refrigeration power consumption of devices such as a refrigerator and the like.

The application numbers are: CN201610952311.7 patent document discloses a refrigerator and a sterilization control method thereof. In the refrigerator structure, an intelligent sterilization module is added. The intelligent sterilization module can automatically detect the position of food through the distance measurement unit, and then the control unit moves the deep ultraviolet LED unit to a proper sterilization position for irradiation sterilization through controlling the driving unit.

The mode can improve the utilization rate of ultraviolet light and improve the sterilization and bacteriostasis efficiency, but a set of detection and driving device is required to be arranged in the refrigerating box, the structure is complex, and the cost is increased; the additional sterilization module and the driving module will occupy the limited refrigerator space.
