Description

Technical Field

[0001] The invention relates to a fresh air system, and in particular to a vertical fresh air isolation system. Background Art

[0002] The world is currently under the threat of COVID-19. Since the beginning of this century, infectious diseases that are mainly transmitted through droplets and aerosols include SARS in 2003, MERS in 2015, and COVID-19 in 2020, as well as respiratory infectious diseases that have long coexisted with humans, such as bacterial meningitis, chickenpox, common cold, influenza, mumps, tuberculosis, and measles. How to prevent such diseases in public places has become an urgent global issue.

[0003] Respiratory transmission is the most difficult mode of transmission to control among all transmission routes. WHO and many domestic papers have pointed out the importance of ventilation in controlling the cluster transmission of respiratory infections. In civil aircraft, trains and other public transportation vehicles and closed buildings, natural ventilation cannot be achieved or cannot meet the ventilation requirements. Fresh air systems and air purification circulation systems are required for forced ventilation.

[0004] The current fresh air systems and air purification equipment all supply air from the top or horizontally, and exhaust air from the top or sideways. Airflow in the environment is mostly in a horizontal flow state. People are distributed horizontally in the space. If there are viruses or pollution sources transmitted by droplets and aerosols in the upwind, people in the downwind are at risk of infection or contamination. Increasing air flow can only reduce the overall concentration of viruses and pollutants in the air, but cannot eliminate infection or pollution, let alone form air isolation between individuals in the same indoor space. The odor generated by pollutants such as sputum and garbage on the ground will also pollute the air under the action of airflow and natural diffusion, affecting air quality and posing a risk of infection. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a vertical fresh air isolation system, which can form a vertical airflow by using a fresh air outlet arranged downward and an exhaust device located below the fresh air outlet in combination, and the air directly enters the exhaust device during exhaust to prevent the air from spreading to the surroundings, which is safe and practical.

[0007] The vertical fresh air isolation system according to the embodiment of the present invention has at least the following technical effects: fresh air is vertically delivered downward into the indoor space through the fresh air outlet on the fresh air device, the air after delivery enters the exhaust device through the breathable floor, and the exhaust device discharges the air carrying droplets and other substances, that is, the air flow in the indoor space is vertical, and the air is delivered from above and discharged from below, so as to avoid the air delivered to the indoor space from spreading around, thereby improving the air quality inhaled by people and reducing the possibility of transmission of viruses and the like.

[0008] According to some embodiments of the present invention, the breathable floor panels are arranged on both sides of the exhaust duct.

[0009] According to some embodiments of the present invention, an air duct is provided at the exhaust inlet, and the air duct has an air duct inlet extending to the interior of the breathable floor.

[0010] According to some embodiments of the present invention, the angle between the direction in which the air guide duct delivers air into the exhaust duct and the air flow direction in the exhaust duct at that location is an acute angle.

[0011] According to some embodiments of the present invention, an exhaust fan is provided in the air guide duct to guide air flow into the exhaust duct.

[0012] According to some embodiments of the present invention, the air duct inlet is connected to a side of the breathable floor and communicates with the cavity of the breathable floor, and the exhaust fan is located inside the air duct inlet.

In addition, an air purifier 130 can be provided between the air inlet 111 and the fresh air outlet 112 to purify the air, thereby improving the air supply quality.

[0029] The exhaust device 200 is provided with a breathable floor 210 and an exhaust duct 220. The breathable floor 210 and the exhaust duct 220 can be arranged on the ground or at the bottom of the vehicle body according to actual conditions. The breathable floor 210 is located below the fresh air outlet 112. A floor through hole 211 is provided above the breathable floor 210 and has a cavity inside, that is, the air sent downward from the fresh air outlet 112 can directly pass through the floor through hole 211 into the cavity of the breathable floor 210; the exhaust duct 220 has an exhaust inlet 221 and an exhaust outlet 222. The exhaust inlet 221 is connected to the cavity of the breathable floor 210, that is, the air entering the breathable floor 210 from the floor through hole 211 eventually flows into the exhaust duct 220 and is discharged from the exhaust outlet 222. Through this structural design, the air sent into the space such as a house or a vehicle will directly enter the exhaust device 200 downward and be finally discharged, and will not spread around after being sent into the space such as a house or a vehicle, thereby spreading the air with substances such as droplets, effectively eliminating the source of danger, and being safe and reliable. It is conceivable that an exhaust fan 250 can be provided in the exhaust duct 220 to provide exhaust power. In addition, a disinfection and sterilization device 260 can also be provided in the exhaust duct 220 before the exhaust outlet 222, so as to disinfect and sterilize the exhaust gas in the exhaust duct 220, and then discharge the pollution-free air, which is safe and environmentally friendly.

[0030] like Figure 1 As shown, a floor cover plate 212 is disposed above the breathable floor 210, and a floor through hole 211 is disposed on the floor cover plate 212. It is conceivable that the floor cover plate 212 is detachable to facilitate cleaning and maintenance of the inside of the breathable floor 210. In addition, an elastic sealing ring may be disposed below the floor cover plate 212 to ensure air tightness and reduce noise generated by walking on it.

[0031] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the breathable floors 210 are arranged on both sides of the exhaust duct 220, so that one exhaust duct 220 can be used by multiple breathable floors 210 on both sides thereof, saving space and cost.

[0032] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, an air duct 230 is provided at the exhaust inlet 221, and the air duct 230 has an air duct inlet 231 extending into the air permeable floor 210. The air duct 230 is provided to guide air into the exhaust duct 220, and the shape of the air duct 230 can be flexibly designed according to the relative positions and shapes of the exhaust duct 220 and the air permeable floor 210, which is simple and practical.

[0033] In some embodiments of the present invention, Figure 4 As shown, the angle between the direction in which the air guide 230 delivers air into the exhaust duct 220 and the direction of the air flow in the exhaust duct 220 is an acute angle. This structure can effectively reduce resistance and facilitate the discharge of air.

[0034] In some embodiments of the present invention, Figure 2 As shown, an exhaust fan 232 is provided in the air duct 230 , and the exhaust fan 232 is located at the air duct inlet 231 to guide the air flow into the exhaust duct 220 .

[0035] In some embodiments of the present invention, Figure 2 As shown, the air duct inlet 231 is connected to the side of the breathable floor 210 and is connected to the cavity of the breathable floor 210, that is, the lowest point of the air duct inlet 231 is higher than the bottom of the breathable floor 210 to prevent liquid in the breathable floor 210 from flowing into the exhaust fan 232; in addition, the exhaust fan 232 is located inside the air duct inlet 231, that is, the air duct 230 blocks the exhaust fan 232 in the vertical direction to prevent liquid from falling into the breathable floor 210 and then entering the exhaust fan 232.

[0036] In some embodiments of the present invention, Figure 2 As shown, the air duct inlet 231 is provided with a filter 233 to prevent debris from entering the exhaust duct 220. It is conceivable that the filter 233 can be provided in the air duct 230 before the exhaust fan 232 to prevent debris from entering the exhaust fan 232.

[0037] In some embodiments of the present invention, Figure 1As shown, a pipe cover plate 223 is provided above the drainage pipe 320, which can protect the pipe on the one hand, and can be designed to be flush with the breathable floor 210 on the other hand. It is conceivable that the pipe cover plate 223 is set to be detachable for easy cleaning and maintenance. In addition, an elastic sealing ring can be provided below the pipe cover plate 223 to ensure air tightness and reduce the noise generated by walking on it.
