Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, specifically a UVC-LED air sterilization device. Background Technology

[0002] Air disinfection devices are important equipment in the field of public health and environmental safety. Their core function is to remove pathogenic microorganisms (such as bacteria and viruses) in the air through physical or chemical means to reduce the risk of airborne diseases and protect the health of people indoors. Traditional air disinfection technologies include filtration and chemical spraying, while ultraviolet (especially UVC band) disinfection technology is increasingly favored due to its advantages such as high efficiency and no chemical residue.

[0003] UVC ultraviolet rays, especially short-wave deep ultraviolet rays in the 265-275nm band, can be absorbed by the DNA or RNA of microorganisms, destroying their molecular structure and causing cell death, thereby achieving efficient sterilization. Most mainstream ultraviolet air disinfection devices on the market use traditional ultraviolet mercury lamps as light sources. Ultraviolet mercury lamps contain gaseous mercury, which poses a risk of leakage and a potential threat to the environment and human health. They also have high energy consumption, and their luminous efficiency decreases rapidly with use, resulting in shortened lamp life and severe light decay. Utility Model Content

[0004] The purpose of this invention is to provide a UVC-LED air sterilization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A UVC-LED air sterilization device includes a housing, a heat dissipation air chamber at the bottom of the housing, a lamp board inside the housing, and multiple LED beads arranged on the lamp board, including LED-UVC single-core LED beads and LED-UVC dual-core LED beads. Side plates are provided on both sides of the outer side of the housing, and multiple heat dissipation holes are opened on the side plates. The heat dissipation air chamber and the heat dissipation holes form a heat dissipation air channel for cooling the lamp board and LED beads.

[0007] The outer shell has a light outlet, and a grille is provided at the light outlet. The grille is provided with multiple upwardly inclined louvers to form an ultraviolet radiation channel for exporting UVC light.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0022] In one embodiment, such as Figure 1-5 As shown, a UVC-LED air sterilization device includes a housing 1, a heat dissipation air chamber 2 at the bottom of the housing 1, a lamp board 5 inside the housing 1, and a plurality of LED beads 4 arranged on the lamp board 5. The LED beads 4 include LED-UVC single-core LED beads and LED-UVC dual-core LED beads. Side plates 9 are provided on both sides of the outer side of the housing 1, and a plurality of heat dissipation holes 11 are opened on the side plates 9. The heat dissipation air chamber 2 and the heat dissipation holes 11 constitute a heat dissipation air channel for cooling the lamp board 5 and the LED beads 4.

[0023] The outer shell 1 has a light outlet 101 on its exterior. A grille 3 is provided at the light outlet 101. Multiple upwardly inclined louvers 14 are provided on the grille 3 to form an ultraviolet radiation channel for directing UVC light. This directs the UVC light outward and forms a three-dimensional radiation disinfection area centered on the device, ensuring that the ultraviolet rays mainly act on the air above and the ceiling, thus avoiding direct exposure to the human body.

[0024] The UVC-LED air sterilization device powers the lamp board 5 via the driver power supply 6, activating the LED-UVC single-core and dual-core lamp beads 4 arranged on it. These emit ultraviolet rays with a center wavelength in the range of 265-275nm. This wavelength is located in the absorption peak range of microbial DNA / RNA, which can effectively destroy the genetic material of bacteria, viruses and other microorganisms in the air that are drawn into the device and along the irradiation path, causing them to lose their ability to reproduce, thereby achieving the purpose of rapid inactivation. During the operation of the device, the LED chip generates a lot of heat. The cool air around the device flows through the heat dissipation air chamber 2 at the bottom, absorbing and carrying away the heat, ensuring that the LED chip can work at a suitable temperature. As an example, the left, right and up and down positions of the various components shown in the attached figure are only one arrangement method. The specific positions are set according to specific needs.

[0025] In one embodiment, such as Figure 1 As shown, a fixing plate 13 is provided on the outer shell 1. The aluminum fixing plate 13 has hanging holes 12. The entire device is fixedly installed on the wall or ceiling with screws and other fasteners.

[0026] In one embodiment, such as Figure 1 As shown, the side plate 9 is provided with fixing screws 10. The side plate 9 is connected to the outer shell 1 by fixing screws 10. Tightening the fixing screws 10 can lock the side plate 9 onto the outer shell 1, which facilitates the assembly, disassembly and subsequent maintenance of the device.

[0027] In one embodiment, such as Figure 1 As shown, a drive power supply 6 is provided on the outer casing 1, and a power cord 7 is provided on the drive power supply 6.

[0028] In one embodiment, such as Figure 1 As shown, the driving power supply 6 is electrically connected to the lamp board 5 to supply power to the LED-UVC lamp beads 4 on it, and a plug 8 is provided at one end of the power line 7.

[0029] The above embodiments of this utility model provide a UVC-LED air disinfection device. The device is fixed to a predetermined position on the wall or ceiling using corresponding screws, bolts and other fasteners through the hanging holes 12 on the aluminum fixing plate 13. The standard plug 8 at the end of the power cord 7 is inserted into the power socket to power the device. The drive power supply 6 provides stable power to the lamp board 5, and the LED-UVC single-core and dual-core lamp beads 4 arranged on it are activated. The lamp beads emit high-intensity short-wave deep ultraviolet rays with a center wavelength of 270nm in the range of 265-275nm. The light is directed through the upward-sloping grille louvers 14 and irradiates the air above and the ceiling area, instantly disinfecting the air flowing through this radiation area and destroying the DNA / RNA of bacteria, viruses and other microorganisms. The upward light avoids direct irradiation of the indoor activity area, thereby achieving safe and continuous air disinfection.

[0030] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
