Description

Multifunctional UV LED Air Purifier

technical field

The multifunctional ultraviolet LED air purification device described in the utility model relates to an air purification device.

Background technique

At present, the formaldehyde contained in the chemical gas released from paints, composite boards and composite floors in home decoration seriously endangers our health. Finding a convenient and effective way to decompose formaldehyde and purify the air is a common concern of everyone. Ultraviolet light stimulates photocatalysts to decompose harmful gases, which is a commonly used method for purifying air.

Photo-catalyst is a photo-semiconductor material with photocatalytic function, which has the characteristics of fresh air, sterilization and antibacterial, anti-mildew, and non-toxic. Nanoscale TiO2 has become the main research and environmental application object of photocatalyst because of its strong redox ability, chemical stability, and environmental friendliness. The energy level of TiO2 is about 3.0eV, which belongs to the excitation range of ultraviolet light (wavelength below 380nm). Therefore, in the application, ultraviolet light must be used as the light source to have the photocatalytic effect.

Existing photocatalyst excitation light sources mainly include sunlight, ultraviolet light tubes, general incandescent lamps, fluorescent lamps or energy-saving fluorescent lamps. These traditional trigger light sources have their own shortcomings, or are limited by time, and cannot effectively play the role of photocatalyst. Either the volume is large, the energy consumption is high, and it will also cause harm to the human body. In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a novel multifunctional ultraviolet LED air purification device, so as to overcome the problems existing in the prior art.

In view of the problems existing in the above-mentioned prior art, the purpose of this utility model is to study and design a novel multifunctional ultraviolet LED air purification device, thereby solving the shortcomings of the existing photocatalyst excitation light source, or limited by time, unable to effectively play The role of photocatalyst. Either the volume is large, the energy consumption is high, and there are problems such as harm to the human body. The multi-functional ultraviolet LED air purification device described in the utility model is composed of a DC stabilized power supply, a housing, a UV LED photocatalytic reactor, a fan, and a spherical mesh freshener vessel, and the DC power supply is installed on the left side of the housing. On the inner wall, the UV LED photocatalytic reactor and the fan are respectively fixed in the center of the housing through brackets, and the spherical mesh freshener container is fixedly installed on the right inner wall of the housing. The UV LED photocatalytic reactor adopts a cylindrical structure, and from the inside to the outside are UV LED light-emitting diodes, photocatalyst coatings, and nanometer photocatalytic nets.

The photocatalyst coating is attached to the nano photocatalytic net. Under the excitation of the ultraviolet LED diode light source, the photocatalyst generates free radical active substances with strong oxidation ability through the photocatalytic oxidation reaction, which can remove formaldehyde, benzene, ammonia, and sulfur in the air. Harmful pollutants such as hydrogen are oxidized and decomposed into non-toxic and tasteless substances such as CO2 and H2O. The effect of the low-power fan is to accelerate the air circulation inside and outside the housing, and the effect of the spherical mesh freshener vessel is to freshen the air.
