In some embodiments, the first outlet 102 may be in communication with the outside of the cabin, the first outlet 102 may be provided with an airflow direction control device 18, and the airflow direction control device 18 may be a valve, a louver, a wind deflector, or other devices capable of controlling the airflow direction. The air flow direction control device 18 controls the air flow direction in at least two directions. One of the directions may be into the cabin and the other direction may be out of the cabin. In some embodiments, a portion of the first outlet 102 is in communication with a vent in the ceiling, floor, or interior side wall of the compartment, and another portion is in communication with the air within the compartment. Control device 16 controls the flow of air to control device 18 to open or close air flow in one or both directions. The control device 16 can realize automatic control according to the opening frequency of the screen door. For example, when the opening frequency of the shield door reaches a preset value, the air flow direction to the outside of the cabin is opened, and when the opening frequency of the shield door is lower than the preset value, the air flow direction to the inside of the cabin is opened. In some embodiments, the control device 16 may also turn on or off the corresponding air flow direction based on a manipulation instruction input by the user through the manipulation device 17. In some embodiments, the airflow direction control device 18 may also be turned on or off by the user. Aiming at different scenes, the air flow direction control device can be controlled according to the air circulation condition of the cabin. For example, during an epidemic situation, when the flux of a patient is large, the shielding door is frequently opened and closed, the frequency of convection of air inside and outside the cabin is high, at this time, the first air outlet 102 and the air circulation direction outside the cabin can be opened through the air flow direction control device 18, at this time, the air inside the cabin can be discharged outside the cabin through the first air outlet 102, negative pressure is formed inside the cabin, and when the shielding door is opened, the air outside the cabin enters the cabin under the action of the negative pressure, so that fresh air outside the cabin is introduced, and the air quality inside the cabin is further improved. On the contrary, if the flux is small, the alternating frequency of the air inside and outside the cabin is low, and at this time, only the first air outlet 102 can be opened to communicate with the air inside the cabin, so as to directly filter, disinfect and sterilize the air inside the sealed cabin.

In some embodiments, the air purification apparatus 1 may be disposed in the cabin by a movable structure, so as to be movable to different positions according to user's needs.

In some embodiments, the air cleaning device 1 may comprise a fixing device 11, and the air cleaning device 1 is fixed on the ceiling, floor or inner side wall of the cabin by the fixing device 11. It will be appreciated that in some embodiments the air cleaning device 1 may also be arranged outside the cabin, for example on the ceiling, outside wall of the cabin. The air inlet 100 and the first air outlet 102 are separately disposed at an interval and respectively communicated with the cabin, so that air in the cabin enters the air duct 104 of the air purification device 1 through the air inlet 100, and is filtered, sterilized and then output to the cabin through the first air outlet 102.

Fig. 4 is a schematic structural diagram of an air purification system according to another embodiment of the present invention.

The difference from the embodiment shown in fig. 1 is that the air purification apparatus 1 is further provided with a second air outlet 103, the second air outlet 103 is independent from the first air outlet 102, and the air flow directions of the first air outlet 102 and the second air outlet 103 are different. For example, one of the first outlet 102 and the second outlet 103 is communicated with the inside of the cabin, air flows into the cabin from the air cleaning device 1, the other is communicated with the outside of the cabin, and air flows out of the cabin from the air cleaning device 1. The first outlet 102 and the second outlet 103 may be controlled by respective air flow direction control devices. The airflow direction control device of the first outlet 102 and the second outlet 103 may be connected to the control device 16, and the control device 16 receives a control command input by a user through the control device 17 to control the opening and closing of the first outlet 102 and the second outlet 103. It will be appreciated that the control means 16 may be automatically controlled in dependence on the frequency at which the screen door is opened. For example, when the opening frequency of the shielding door reaches a preset value, the air outlet communicated with the outside of the cabin is opened, and when the opening frequency of the shielding door is lower than the preset value, the air outlet communicated with the inside of the cabin is opened. In some embodiments, the opening and closing of the valves of the first outlet 102 and the second outlet 103 can be controlled by the user. The opening and closing of the airflow direction control devices of the first air outlet 102 and the second air outlet 103 are similar to the opening and closing of the airflow direction control device 18, and for different scenarios, the corresponding airflow direction control devices can be controlled according to the airflow condition of the cabin, which is not described herein again.

In some embodiments, the air purification system may include two or more air purification devices 1, for example, one of which is disposed on the ceiling of the cabin, the other is disposed on the floor of the cabin, or disposed on different inner side walls of the cabin, so as to further improve the air purification effect.

In some embodiments, when two or more air purification devices 1 are provided in the air purification system, the air flow direction of the first air outlet 102 of one air purification device 1 is different from the air flow direction of the first air outlet 102 of another air purification device 1. For example, one flowing into the cabin and one flowing out of the cabin.

It is understood that, in some embodiments, the air cleaning device 1 may further include a second air inlet, and the second air inlet is communicated with the outside of the cabin, so as to facilitate the air outside the cabin to enter the cabin. For example, when the air outlet communicated with the outside of the cabin is opened, the air in the cabin is discharged out of the cabin, and negative pressure is generated in the cabin, the second air inlet can be opened, so that the air outside the cabin is allowed to enter the air purification device 1 through the second air inlet, and is conveyed into the cabin after being filtered, sterilized and disinfected, so that the air communication between the inside and the outside of the cabin is realized, and the air quality in the cabin can be further improved due to the introduction of the fresh air outside the cabin.
