[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes a disinfection device consisting of a photocatalytic layer and multiple ultraviolet lamps. Under ultraviolet irradiation, the surface of the photocatalytic layer generates highly oxidizing hydroxyl radicals and superoxide anion radicals. These radicals can rapidly react with harmful microorganisms and organic pollutants in the air, such as bacteria, viruses, and formaldehyde, through oxidation-reduction reactions, destroying their cell structure or molecular chains and decomposing them into harmless substances such as carbon dioxide and water.

[0022] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The invention will now be further described with reference to the accompanying drawings and embodiments:

[0023] Please see Figure 1-3 An indoor microbial disinfection and purification system includes a housing with an air inlet and an air outlet. The housing is equipped with a purification device, a disinfection device, and a centrifugal fan, which are arranged sequentially along the airflow direction. The disinfection device includes a photocatalyst layer and multiple ultraviolet lamps, which are arranged sequentially from the air inlet to the air outlet.

[0024] The air inlet is used to draw in indoor air to be treated, and the air outlet is used to discharge the purified and disinfected air into the indoor environment. The combination of the purification device, the disinfection device and the centrifugal fan enables the air to be purified and disinfected efficiently along the path from the air inlet to the air outlet.

[0025] The disinfection device consists of a photocatalyst layer and multiple ultraviolet lamps, which work together to achieve highly efficient air disinfection. Specifically, the photocatalyst layer uses nano-sized titanium dioxide as the main active material, uniformly coated on the surface of a honeycomb metal mesh carrier with high strength and corrosion resistance. The honeycomb structure design greatly increases the specific surface area of ​​the photocatalyst, allowing more air to come into contact with the photocatalyst material per unit area. Under ultraviolet irradiation, the surface of the photocatalyst material generates highly oxidizing hydroxyl radicals and superoxide anion radicals. These radicals can rapidly react with harmful microorganisms and organic pollutants in the air, such as bacteria, viruses, and formaldehyde, through oxidation-reduction reactions, destroying their cell structure or molecular chains and decomposing them into harmless substances such as carbon dioxide and water, thereby achieving the purpose of disinfection and purification.

[0026] The air undergoes initial oxidation and decomposition disinfection through the photocatalytic layer, and then enters the ultraviolet lamp irradiation area to receive high-intensity ultraviolet radiation, achieving dual disinfection protection. This greatly enhances the disinfection effect on various microorganisms and pollutants in the air, ensuring that the air treated by the disinfection device meets high standards of cleanliness.

[0027] Furthermore, the housing is provided with a first cavity and a second cavity, the air inlet, the first cavity, the second cavity and the air outlet are connected in sequence, the purification device and the disinfection device are arranged in the first cavity in sequence along the direction from the air inlet to the air outlet, and the centrifugal fan is arranged in the second cavity.

[0028] The air inlet, first chamber, second chamber, and air outlet are connected in sequence to form an air circulation channel. Air enters the housing from the air inlet and passes through the purification device and disinfection device in sequence before being discharged from the air outlet. A centrifugal fan is installed in the second chamber, which serves as the power source for airflow. Through its operation, it generates suction, which causes indoor air to enter the system from the air inlet, pass through the purification device and disinfection device in sequence, and then be discharged into the room through the air outlet.

[0029] Furthermore, the first cavity is provided with a support plate, and the purification device and disinfection device are installed on the support plate.

[0030] The support plate is installed in the first cavity as a load-bearing structure to securely install the purification and disinfection devices and ensure stability during system operation.

[0031] Furthermore, the photocatalyst layer is mounted on the support plate, and the ultraviolet lamp tube is mounted on the support plate via a fixing bracket.

[0032] Furthermore, the multiple ultraviolet lamps are arranged at equal intervals.

[0033] Multiple ultraviolet lamps are arranged at equal intervals to ensure that the ultraviolet lamps can evenly irradiate the photocatalyst layer, avoiding incomplete disinfection in some areas due to uneven irradiation.

[0034] Furthermore, the purification device includes a pre-filter layer and an activated carbon filter layer, which are sequentially arranged within the first cavity. The pre-filter layer and the activated carbon filter layer are mounted on a support plate.

[0035] The pre-filter layer is used to filter larger particles in the air, effectively intercepting impurities such as dust and hair, and initially purifying the air; the activated carbon filter layer utilizes the rich pore structure and strong adsorption properties of activated carbon to adsorb harmful gases and various odors in the air, further purifying the air and providing better air conditions for subsequent disinfection treatment.

[0036] Furthermore, the centrifugal fan is a turbine centrifugal fan.

[0037] The centrifugal fan is a turbine centrifugal fan, which is connected to a motor (not shown in the figure). During operation, the motor drives the turbine centrifugal fan to rotate. The high-speed rotation of the impeller creates a strong centrifugal force field inside the fan, which throws the intake air radially out, generating stable and strong airflow power, providing a reliable guarantee for the air circulation of the entire system.

[0038] Furthermore, the air inlet is located above the first cavity, and the air outlet is located on the side wall of the second cavity. The housing is detachably connected to a top cover, and the air outlet is located on the top cover.

[0039] By placing the air outlet on the side wall of the second cavity of the casing, the purified air can be ejected horizontally, forming a transverse airflow in the room, which mixes fully with the original indoor air, accelerates the diffusion speed of the air, and achieves rapid indoor air renewal.

[0040] Furthermore, a negative ion generator is installed inside the housing, and the second cavity is provided with a carbonized fiber wire. One end of the carbonized fiber wire is electrically connected to the negative ion generator, and the other end of the carbonized fiber wire is located at the air outlet.

[0041] The negative ion generator generates a negative high voltage through a high-voltage module, which is transmitted to the end of the carbonized fiber wire via an insulated wire for tip discharge. Under the effect of tip discharge, oxygen molecules in the surrounding air are ionized to generate negative oxygen ions. These charged particles undergo heterogeneous aggregation with suspended particulate matter through Coulomb force, forming large-diameter agglomerates that settle under gravity, thereby achieving the removal of aerosol particulate matter and the neutralization of odor molecules.

[0042] By incorporating a negative ion generator and carbonized fiber wire, the purified air discharged from the air outlet is enriched with negative ions, further enhancing the purification effect on indoor air and effectively improving indoor air quality.

[0043] The main functions of this utility model are:

[0044] This invention utilizes a disinfection device comprised of a photocatalytic layer and multiple ultraviolet lamps. Under ultraviolet irradiation, the surface of the photocatalytic layer generates highly oxidizing hydroxyl radicals and superoxide anion radicals. These radicals rapidly react with harmful microorganisms and organic pollutants in the air, such as bacteria, viruses, and formaldehyde, through oxidation-reduction reactions, destroying their cell structure or molecular chains and decomposing them into harmless substances like carbon dioxide and water. After initial oxidation and decomposition disinfection by the photocatalytic layer, the air enters the ultraviolet lamp irradiation area, receiving high-intensity ultraviolet radiation. This dual disinfection ensures significantly improved effectiveness against various microorganisms and pollutants in the air, guaranteeing that the air treated by the disinfection device meets high standards of cleanliness.
