[0002] Subway is a form of urban public transportation. The term can be interpreted in two ways: First, it refers to a predominantly underground urban rail transit system, often shortened to "underground railway" or "subway." Many such systems, to accommodate the construction environment and consider construction and operating costs, may transition to surface or elevated sections outside the city center. Second, it encompasses a wide range of high-density, high-capacity urban rail transit systems with dedicated underground and surface rights in metropolitan areas. Subways have evolved from surface railway systems into a rapid, high-capacity urban rail transit mode powered by electricity. Their lines are typically laid in underground tunnels, but some transition from underground to surface or elevated sections outside the city center.

[0026] Please see Figure 1-2 An air purification and circulation device for subway cars, comprising the car body 1;
[0027] A ventilation assembly 2 is installed at the upper end of the carriage body 1;
[0028] An exhaust system 3 is installed on the side wall of the carriage body 1;
[0029] A purification component 4 is installed between the exhaust component 2 and the ventilation component 3.
[0030] By installing a ventilation component 2, an exhaust component 3, and a purification component 4 on the carriage body, the ventilation component 2 draws away the air exhaled by passengers in the carriage body 1, the purification component 4 purifies the air, and the exhaust component 3 blows the purified air back into the carriage body 1, thus realizing the internal circulation ventilation of the carriage body 1.
[0031] As a further aspect of the present invention: the ventilation assembly 2 includes a ventilation fan 21, which is installed on the upper part of the carriage body 1. The air inlet of the ventilation fan 21 is connected to a plurality of first air inlets 22 and second air inlets 23. The first air inlets 22 are located on the upper inner part of the carriage body 1, and the second air inlets 23 are located on the lower part of the left and right side walls inside the carriage body 1. The air outlet of the ventilation fan 21 is connected to the purification assembly 4.
[0032] The exhaust fan 21 draws air from the upper and lower parts of the carriage body 1. The air exhaled by passengers, whether sitting or standing, has a certain temperature and will rise, so it can be drawn away through the first exhaust vent 22. At the same time, the lower part of the carriage body 1 is where the passengers' feet are, so it can draw away the air through the second exhaust vent 23. While the second exhaust vent 23 draws away the air from the passengers' feet, it also generates a certain amount of external airflow, which can improve the comfort of the passengers' feet and help relieve the fatigue in their feet.
[0033] As a further aspect of the present invention: the purification component 4 includes an air collection chamber 41, which is disposed on one side of the upper end of the carriage body 1. The air outlet of the exhaust fan 21 is connected to the air collection chamber 41. The air inlet of the air collection chamber 41 is provided with a plurality of air filters 42. The air outlet of the air collection chamber 41 is connected to the exhaust component 3. It also includes a plurality of air quality detectors 43, which are spaced apart on the inner side wall of the carriage body 1.
[0034] Air quality detectors 43 are installed at various locations within the carriage body 1, enabling them to detect different locations within the carriage body 1 and ensuring the accuracy of the detection. When the exhaust fan 21 draws air from the carriage into the air collection chamber 41, it activates a corresponding number of air filters 42 based on the detection values of the air quality detectors 43. The air filters 42 are ultra-high efficiency filters (removing dust particles ≥0.1μm, with an initial resistance ≤280), ensuring that the air entering the air collection chamber 41 after passing through the air filters 42 meets the usage standards of the subway carriage.
[0035] As a further aspect of the present invention: the exhaust assembly 3 includes a blower 31, which is installed at the lower end of the air outlet of the air collection chamber 41. The air outlet of the blower 31 is provided with a plurality of first air outlets 32 and second air outlets 33. The first air outlets 32 are respectively located on the upper part of the left and right side walls inside the carriage body 1, and the second air outlets 33 are respectively located in the middle part of the left and right side walls inside the carriage body 1.
[0036] The purified air in the air collection chamber 41 is returned to the carriage body 1 by the blower 31. After the air is filtered to remove dust, the air temperature will drop. Therefore, the purified air discharged from the first air outlet 32 will gradually decrease, which will make standing passengers feel comfortable. The second air outlet 33 is set relative to the back of the passenger, which can make sitting passengers feel comfortable, thus improving the overall comfort of the carriage body 1.
[0037] As a further aspect of the present invention: an aromatherapy cover 34 is provided on the outer side of each first air outlet 32 and second air outlet 33; a wind speed control valve 35 is also provided inside the first air outlet 32 and the second air outlet 33; and a control panel 36 electrically connected to the wind speed control valve 35 is provided on the inner wall of the carriage body 1.
[0038] The aromatherapy cover 34 can impart a certain fragrance to the air exhausted into the carriage body 1, making passengers more comfortable, and at the same time, it can protect the first air outlet 32 and the second air outlet 33. The wind speed regulating valve 35 can intelligently control the exhaust wind speed of the first air outlet 32 and the second air outlet 33 according to the current indoor temperature, in order to improve the comfort of passengers in the carriage. Meanwhile, the control panel 36 can independently control the small range of exhaust wind speed of the carriage body 1, which can be adjusted according to the passengers' feelings and needs at the time, and can fully consider the passengers' riding comfort.
[0039] As a further aspect of the present invention, a temperature regulating component 5 is also provided inside the air collecting cavity 41. The temperature regulating component 5 includes several temperature regulating water pipes 41 disposed inside the air collecting cavity 41. Electric heating rods 52 and semiconductor cooling chips 53 are respectively disposed at intervals inside the temperature regulating water pipes 51.
[0040] The liquid in the temperature-regulating water pipe 51 is heated by an electric heating rod 52, and the air in the air collection cavity 41 is heated to a certain temperature through heat transfer. This air is suitable for use in the carriage body 1 when the weather is cold. The liquid in the temperature-regulating water pipe 51 is cooled by a semiconductor cooling chip 53, and the air in the air collection cavity 41 is cooled through temperature conduction. This air is suitable for use in the carriage body 1 when the weather is hot. At the same time, the heating surface of the semiconductor cooling chip 53 is located on the outside of the air collection cavity 41, and the wind generated by the subway movement is used to dissipate heat from it, thus saving energy.
[0041] As a further aspect of the present invention, the air collection chamber 41 is also provided with a number of ultraviolet germicidal lamps 44.
[0042] After the purified air is discharged into the air collection chamber 41, the air can be effectively disinfected and sterilized by turning on the ultraviolet germicidal lamp 44, thereby meeting the safety standards for air used in the subway.
[0043] As a further embodiment of the present invention: a manhole 45 is provided on the outside of the air collecting chamber 41, an air outlet pipe 46 is provided on the outside of the air collecting chamber 41, and solenoid valves 47 are respectively provided between the air collecting chamber 41 and the air inlet end of the blower 31 and at the air outlet pipe 46.
[0044] The manhole 45 allows for cleaning of the air collection chamber 41 to ensure its internal air quality. After cleaning, the solenoid valve 47 between the air collection chamber 41 and the blower 31 is closed, and the solenoid valve 47 at the air outlet pipe 46 is opened to discharge the cleaned air from the air collection chamber 41 through the air outlet pipe 46. Once the air in the air collection chamber 41 meets the usage standards, the solenoid valve 47 between the air collection chamber 41 and the blower 31 is opened, and the solenoid valve 47 at the air outlet pipe 46 is closed to discharge the air from the air collection chamber 41 into the carriage body 1.
