Description

Technical Field

[0001] This utility model relates to the field of infectious disease prevention and control technology, specifically to a ceiling-mounted air purification and disinfection device for infectious disease prevention and control. Background Technology

[0002] A crucial part of infectious disease prevention and control is blocking the spread of viruses. Public places are densely populated and have high mobility, allowing viruses to remain suspended in the air for extended periods, which greatly facilitates their transmission. Therefore, disinfecting the air in public areas is particularly important, effectively reducing the risk of infection for healthy individuals and breaking the chain of transmission. Currently, the main methods for air purification and virus disinfection in public places are manual spraying of disinfectants and the use of air purification devices. Manual spraying is time-consuming, labor-intensive, and uneven, while air purification devices occupy considerable space and primarily purify the lower and middle levels, failing to effectively disinfect the upper air. Furthermore, existing devices and methods often have insufficient disinfection effects and cannot effectively block the virus transmission chain. Therefore, we propose a ceiling-mounted air purification and disinfection device for infectious disease prevention and control. Utility Model Content

[0003] The purpose of this invention is to provide a ceiling-mounted air purification and disinfection device for the prevention and control of infectious diseases, so as to solve the problems mentioned in the background art.

[0004] A ceiling-mounted air purification and disinfection device for infectious disease prevention and control includes a cylindrical disinfection box. An air guiding device is installed inside the disinfection box. A flared air inlet is located at the lower end of the disinfection box, and the upper end of the air inlet is connected to an air intake cylinder. A first partition is connected to the upper end of the air intake cylinder. A connecting pipe is vertically connected to the center of the upper end of the first partition. Three second partitions are horizontally arranged from top to bottom between the connecting pipe and the inner wall of the disinfection box. Air guiding holes are opened on the second partitions. The three second partitions divide the interior of the disinfection box into sections from top to bottom. The system has three disinfection chambers connected vertically by air vents. Each chamber contains disinfectant. An exhaust port is located on the upper side of the disinfection box. Each chamber is also equipped with a U-shaped air vent. One end of the air vent is mounted on the first partition and connected to the air intake cylinder. The other end of the air vent is inserted into the lowest disinfection chamber. The uppermost part of the air vent is higher than the disinfection chamber, allowing air from the air inlet to enter the disinfection chamber through the air vent and preventing the disinfectant in the disinfection chamber from flowing back into the air intake cylinder.

[0005] The air guiding device includes a motor, which is installed inside the air duct via a connecting rod. The upper output shaft of the motor is connected to a long connecting shaft, which can drive the long connecting shaft to rotate. The long connecting shaft passes through a connecting pipe and is inserted into the upper part of the disinfection box. Several first air guiding blades are provided on the long connecting shaft located inside the air duct, which draws air into the air duct from the air inlet. Several second air guiding blades are provided on the long connecting shaft located at the upper part of the disinfection box, which discharges the air in the upper part of the disinfection box from the exhaust port.

[0006] Preferably, a bearing is provided inside the connecting pipe, and the bearing is sleeved outside the long connecting shaft to ensure the stable rotation of the long connecting shaft.

[0007] Preferably, the upper end of the disinfection box is provided with an extension portion, and the extension portion is provided with a connecting hole, so that the disinfection box can be easily fixed to the indoor ceiling through the extension portion.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The motor of the air-guiding device drives the rotation of the long connecting shaft, causing the first and second air-guiding blades to rotate. This draws in air from below the indoor disinfection box, which then passes through an air intake pipe and a U-shaped air duct into the disinfection chamber. After passing through three disinfection chambers from bottom to top, the viruses in the air come into prolonged and thorough contact with the disinfectant solution inside, resulting in effective disinfection. Finally, the air is discharged laterally from the exhaust port by the action of the second air-guiding blade. The discharged air contains a certain concentration of disinfectant, effectively disinfecting viruses in public places. At the same time, because the disinfection box is installed on the ceiling, it can fully absorb and treat the air in the space below, and the discharged airflow containing disinfectant flows from top to bottom within the space, achieving full coverage and disinfection without dead angles, effectively improving the air disinfection treatment effect and blocking the virus transmission chain.

An extension 17 is provided on the upper end of the disinfection box 1, and a connecting hole 171 is provided on the extension 17 to facilitate fixing the disinfection box 1 to the indoor ceiling. An air guiding device 2 is provided inside the disinfection box 1. A trumpet-shaped air inlet 11 is provided at the lower end of the disinfection box 1. The upper end of the air inlet 11 is connected to an air intake cylinder 12. A first partition 13 is connected to the upper end of the air intake cylinder 12. A connecting pipe 14 is vertically connected to the center of the upper end of the first partition 13. Three second partitions 15 are horizontally arranged from top to bottom between the connecting pipe 14 and the inner wall of the disinfection box 1. Air guiding holes 151 are provided on the second partitions 15. The three second partitions 15 divide the disinfection box 1 into three disinfection chambers 16 from top to bottom. Hole 151 connects the three disinfection chambers 16 vertically. The three disinfection chambers 16 are filled with disinfectant. An exhaust port 101 is provided on the upper side of the disinfection box 1. A U-shaped air guide pipe 3 is also provided in each disinfection chamber 16. One end of the air guide pipe 3 is installed on the first partition 13 and connected to the air intake cylinder 12. The other end of the air guide pipe 3 is inserted into the lowest disinfection chamber 16. The uppermost part of the air guide pipe 3 is higher than the disinfection chamber 16, so that the air in the air inlet 11 can enter the disinfection chamber 16 through the air guide pipe 3 and prevent the disinfectant in the disinfection chamber 16 from flowing back into the air intake cylinder 12. After the airflow passes through the air intake cylinder 12, it enters the disinfection chamber 16 through the U-shaped air guide pipe 3. After passing through the three disinfection chambers 16 from bottom to top, the virus in the air comes into full contact with the disinfectant in the disinfection chamber 16 for a long time and is effectively disinfected.

[0015] The air guiding device 2 includes a motor 21, which is installed inside the air duct 12 via a connecting rod 22. The upper output shaft of the motor 21 is connected to a long connecting shaft 23, and the motor 21 can drive the long connecting shaft 23 to rotate. The long connecting shaft 23 passes through a connecting pipe 14 and is inserted into the upper part of the disinfection box 1. A bearing 26 is installed inside the connecting pipe 14 and is sleeved on the outside of the long connecting shaft 23 to ensure the stable rotation of the long connecting shaft 23. Several first air guiding blades 24 are provided on the long connecting shaft 23 located inside the air duct 12. The first air guiding blades 24 draw air into the air duct 12 from the air inlet 11. Several second air guiding blades 25 are provided on the long connecting shaft 23 located at the upper part of the disinfection box 1. The second air guiding blades 25 discharge the air in the upper part of the disinfection box 1 from the exhaust port 101.

[0016] Working principle: When disinfecting the air, the device is first installed on the indoor ceiling. Then, disinfectant is filled into the disinfection chamber 16. After the motor 21 of the air guiding device 2 is powered on, the motor 21 drives the rotation of the long connecting shaft 23, causing the first air guiding blade 24 and the second air guiding blade 25 to rotate. This draws in the air below the indoor disinfection box 1, which then passes through the air intake cylinder 12 and enters the disinfection chamber 16 through the U-shaped air guiding pipe 3. After passing through the three disinfection chambers 16 from bottom to top, the viruses in the air come into full contact with the disinfectant in the disinfection chambers 16 for a long time, achieving effective disinfection. Finally, the air is discharged horizontally outward from the exhaust port 101 through the action of the second air guiding blade 25. The discharged air contains a certain concentration of disinfectant components, which can effectively disinfect viruses in public places.
