The bottom cover plate 410 is fixed to the lower end of the shield 100 by a fixing member 530. To ensure effective retention and material reduction, the diameter of bottom cover plate 410 is less than the maximum radius of shield 100.
As shown in fig. 5-6, the present invention provides a second embodiment of an air purification system, which comprises a fan (not shown) located at the upstream, and a light energy purification module located at the downstream, wherein the light energy purification module comprises a shield 1000 having a plurality of through holes 1005 on the surface and being hollow inside, and an ultraviolet lamp tube assembly 2000 at least partially located inside the shield 1000, wherein ultraviolet rays emitted from the ultraviolet lamp tube assembly 2000 and the shield 1000 undergo a photocatalytic reaction to generate a plurality of beneficial factors such as superoxide ions, hydroxyl radicals, hydroxyl ions, etc., and are blown out from the inside to the outside of the plurality of through holes 1005, so as to rapidly capture and remove indoor pollution such as bacteria, viruses, harmful gases, and respirable particles in the air.
The shield 1000 is a porous material, and is made of at least one or more of the following components: silicon carbide, aluminum oxide, silicon oxide, titanium dioxide, zinc oxide, tin oxide, and the like. The surface of the shield 1000 is at least partially curved, preferably cylindrical in this embodiment to ensure a sufficient reaction area, and the thickness of the shield 1000 is 0.5mm to 5 mm. In order to ensure sufficient optical energy purification reaction and to ensure miniaturization of the product, the height of the shield 1000 is more than twice its diameter.
The ultraviolet lamp tube assembly 2000 is extended in a straight line shape and coincides with the central axis of the shield 1000 and includes a lamp cover 2100 at the top end, and a lamp tube 2200 extended from the lamp cover 2100 to the bottom end, the ultraviolet wavelength of the lamp tube 2200 being 10-400nm, preferably 185 nm.

To ensure effective retention and cost reduction, the diameter of the bottom cover plate 4100 is smaller than the radius of the shield 1000.
The porous material in the protective cover of the invention is preferably located outside or inside the ultraviolet lamp tubeFor semiconductor photocatalytic materials, the generated electrons and holes do not immediately combine and disappear, but rather stay for a short time, albeit very short in the order of picoseconds, due to the very short residence time, the photocatalytic properties are developed. The electrons of the transition are captured by the dissolved oxygen adsorbed on the surface of the semiconductor particles to form superoxide anions (O)2 -),O2+e-→O2 -(superoxide anion). The holes oxidize hydroxide ions and water adsorbed on the surface of the scavenger into hydroxyl radicals (OH)-),H2O+h+→ OH (hydroxyl radical). The superoxide anion and hydroxyl radical have strong oxidizability, and can oxidize most organic matters to final product CO2And H2O, even for some inorganic substances. The reaction energy is about 240Kcal/mol, the oxidizing power is second to periodic acid, the oxidizing power is stronger than that of typical oxidants such as ozone, and almost all chemical bonds forming organic molecules can be cut and decomposed. Therefore, when the free hydroxyl group (. OH) encounters an organic compound such as formaldehyde or a microorganism such as bacteria or viruses, it is oxidized and decomposed. The reaction rate is very fast, about 1000 times that of atomic oxygen, which is 100 ten thousand times that of ozone. Taking formaldehyde as an example, the reaction equation is as follows: HCHO (Formaldehyde) + (. OH) → H2O+CO2
The porous material can generate superoxide ions, hydroxyl and the like under the action of ultraviolet rays, oxygen molecules in the air are rapidly decomposed to generate free oxygen, namely active oxygen, and the free oxygen carries out imbalance of positive and negative electrons and needs to be combined with the oxygen molecules to further generate enough ozone, and the ozone, the superoxide ions, the hydroxyl and the like have extremely strong oxidation effect on organic matters, so that malodorous gas substances are degraded and converted into low molecular compounds, water and carbon dioxide, thus toxic and harmful gases are oxidized and decomposed in extremely short time, various bacteria can be effectively killed, and toxins released by the bacteria or fungi can be decomposed and harmlessly treated; meanwhile, the paint also has the functions of deodorization, stain resistance and the like. Therefore, the optical energy purification module can be widely applied to the aspects of air purification, air conditioning, water treatment and the like.
The invention has the advantages of simple structure, long service life, high purification efficiency, peculiar smell elimination, bacteriostasis and improvement of user comfort level through the porous material.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
