Description

A no-dead-angle intelligent deep ultraviolet sterilization and disinfection device

Technical Field

The utility model relates to the technical field of sterilization and disinfection, and in particular to a no-dead-angle intelligent deep ultraviolet sterilization and disinfection device.

Background Art

Public areas such as wash basins and toilets are important media for the breeding, reproduction and spread of bacteria and viruses. At present, the main method of sterilizing and disinfecting the air in public areas is to spray alcohol, disinfectant, etc., but since alcohol cannot be sprayed throughout the space, there are still problems such as volatilization, untimely spraying, and explosion when exposed to open flames, resulting in poor sterilization and disinfection effects and high safety risks. Ultraviolet rays, especially deep ultraviolet rays in the UVC band with a wavelength below 280nm, can destroy the molecular structure of microorganisms in a very short time, causing bacteria to die or unable to reproduce, thereby achieving efficient disinfection of bacteria and viruses, and has become one of the important means to curb the spread of bacteria and viruses.

Traditional ultraviolet disinfection devices are mercury lamps, and the emission of mercury will cause serious environmental pollution. During use, the breakage of mercury lamps will cause huge safety hazards, so the safety issues of mercury lamps limit their promotion and application in the field of sterilization and disinfection in public places. Therefore, deep ultraviolet LEDs, which are more environmentally friendly, lightweight and portable, and have low power consumption than mercury lamps, will inevitably become the mainstream of ultraviolet light sources in the future.

At present, most of the deep ultraviolet LED sterilization lamps on the market are handheld or panel-type sterilization lamps. The handheld method is used to sterilize and disinfect the disinfection area, which makes the operation more cumbersome, and there is also a huge risk of human body being easily damaged by deep ultraviolet radiation during operation. Panel-type sterilization lamps can only sterilize and disinfect the air and the surface of objects in a certain direction, and cannot sterilize and disinfect the surrounding air efficiently without dead angles, resulting in poor sterilization and disinfection effect on viruses in the surrounding air.

The composition of the nanoparticles can be TiO2, ZnO, CdS, WO3, Fe2O3, PbS, SnO2, ZnS, SrTiO3, SiO2, etc., and the size of the nanoparticles is between 50nm-50μm.

In some embodiments, the LED lamp beads also include infrared lamp beads, and the emission wavelength of the infrared lamp beads is 1000-2000nm.

In this embodiment, infrared light can attract mosquitoes to attach to the vicinity of the intelligent deep ultraviolet sterilization and disinfection device 100 without dead angles, and kill them through the high-energy light emitted by the deep ultraviolet LED lamp beads 102.

In some embodiments, the spectrum wavelength of the LED lamp beads covers 200-365nm.

Furthermore, in this embodiment, 360-600 nm is the sensitive wavelength range of mosquitoes.

In some embodiments, a plurality of lamp bead installation areas are provided on the surface of the shell, and the angle of the ultraviolet irradiation area formed when the shell rotates around the rotation axis constrained by the first rotating mechanism 106 is 180-330°.

In this embodiment, when the shell rotates around the rotation axis constrained by the first rotating mechanism 106, multi-angle and full coverage of the ultraviolet irradiation area is guaranteed, so that the range of sterilization and disinfection is as large as possible.

In some embodiments, the lamp bead installation area includes one to three lamp bead installation holes, and the lamp bead installation holes are provided with LED lamp bead sockets, and the LED lamp bead sockets are connected to the control mechanism 107 through the wire 108.

In this embodiment, the lamp bead installation area includes one to three lamp bead installation holes to ensure that each lamp bead installation area has both deep ultraviolet LED lamp beads and visible light or near ultraviolet band LED103, thereby ensuring that the ultraviolet area can be indicated by visible light.

The first fluorescent plate is irradiated by the deep ultraviolet LED lamp beads 102 over a larger area, and the fluorescent effect produced is better.

In some embodiments, an infrared detection device is used to detect whether there is a person in the room;

When there is no person in the room, the control mechanism 107 turns on the ultraviolet lamp bead circuit to power the ultraviolet lamp bead, and the deep ultraviolet light excites the first fluorescent plate to emit blue light.
