The first air inlet 12 is located between the two sides of the first isolation lifting curtain devices 17. The first isolation lifting curtain device 17 includes a first roller shutter drive roller and a first isolation curtain 171 disposed on the first roller shutter drive roller. The first roller shutter drive roller can drive the first isolation curtain 171 to roll up or unfold. The first housing 1 is mounted on a wall by attaching its back side. A second housing 2... The system includes a second ventilation cavity 21, a second air inlet 22, a second connecting port 23, and a rotating part 24. The second ventilation cavity 21 is connected to the second air inlet 22 and the second connecting port 23. The second air inlet 22 is located on the front of the second housing 1. The rotating part 24 is hinged to the front of the first housing 1. The second housing 2 has second isolation lifting curtain devices 26 on both sides of the front edge. The second air inlet 22 is located between the two second isolation lifting curtain devices 26 on both sides. The two second isolation lifting curtain devices 26 on both sides are correspondingly arranged with the two first isolation lifting curtain devices 17 on both sides. The second isolation lifting curtain device 26 includes a second roller shutter drive roller and a second isolation curtain 261 disposed on the second roller shutter drive roller. The second roller shutter drive roller can drive the second isolation curtain 261 to roll up or unfold. A rotating device 4 is disposed on the first housing 1 and is connected to the rotating part 24. A connecting channel 3 is also included. The interior is hollow, and the two ends of the connecting channel 3 are connected to the first connecting port 14 and the second connecting port 23, respectively. Under the action of the rotating device 4, the second housing 2 can rotate relative to the first housing 1 through the rotating part 24 to change the orientation angle of the front of the second housing 2. Specifically, the exhaust device 111 is an exhaust fan, and the angle between the bottom surface of the first housing 1 and the front surface of the second housing 2 is 180° to 280°.

[0042] The working principle of this embodiment is as follows:

[0043] 1) Start the exhaust device 111 and the disinfection device 112. Under the action of the exhaust device 111, negative pressure is formed inside the first ventilation chamber 11.

[0044] 2) The air surrounding the air sterilizer enters the first ventilation chamber 11 through the first air inlet 12, then passes through the exhaust device 111 and the sterilization device 112, and finally exits from the air outlet 13; and / or,

[0045] The air around the air sterilizer enters the second ventilation chamber 21 through the second air inlet 22, then passes through the second connection port 23, the connection channel 3 and the first connection port 14 in sequence to enter the first ventilation chamber 11, then passes through the exhaust device 111 and the sterilization device 112, and finally is discharged from the air outlet 13.

[0046] 3) As the air passes through the disinfection device 112, the disinfection device 112 disinfects the air.

[0047] 4) When people are moving around indoors and their positions are uncertain, the second housing 2 is set to the initial closed state, and the front of the second housing 2 is parallel to the front of the first housing 1, that is, the second air inlet 22 is parallel to the front of the first housing 1, and the angle between the bottom surface of the first housing 1 and the front surface of the second housing 2 is 270-280°; at this time, the air sterilizer has the largest exhaust disinfection area and the exhaust disinfection effect is the most extensive.

[0048] 5) When personnel linger under the air sterilizer for an extended period, the second housing 2 is opened. Under the action of the rotating device 4, the second housing 2 rotates relative to the first housing 1 via the rotating part 24 to change the orientation angle of the front of the second housing 2 until the front of the second housing 2 is parallel to the bottom surface of the first housing 1, that is, the second air inlet 22 is parallel to the bottom surface of the first housing 1, and the angle between the bottom surface of the first housing 1 and the front of the second housing 2 is 180°. At this time, the exhaust disinfection area of ​​the air sterilizer is below it, and the exhaust disinfection effect is strong.

[0049] 6) When personnel need to be isolated, place the isolated personnel under the air sterilizer and open the second housing 2. Under the action of the rotating device 4, the second housing 2 rotates relative to the first housing 1 through the rotating part 24 to change the orientation angle of the front of the second housing 2 until the front of the second housing 2 is parallel to the bottom surface of the first housing 1, that is, the second air inlet 22 is parallel to the bottom surface of the first housing 1, and the angle between the bottom surface of the first housing 1 and the front of the second housing 2 is 180°. Then, activate the first isolation lifting curtain device 17 on both sides. Under the forward rotation of the first roller shutter drive roller, the first isolation curtain 171 is pulled down. At the same time, activate the second isolation lifting curtain device 26 on both sides. Under the forward rotation of the second roller shutter drive roller, the second isolation curtain 261 is pulled down. After the first isolation curtain 171 and the second isolation curtain 261 are pulled down, the first housing 1 The wall attached to its back, the first isolation curtain 171 on both sides and the second isolation curtain 261 on both sides form a semi-enclosed space; under the action of the exhaust device 111, the semi-enclosed space forms a negative pressure, thereby blocking the air inside the semi-enclosed space, that is, the aerosol of the isolated personnel will not diffuse outward, thus achieving the isolation function.

[0050] This embodiment has at least the following beneficial effects:

[0051] 1) In this embodiment, a second air inlet 22 is provided on the second housing 2, so that the air around the air sterilizer can enter the first ventilation cavity 11 through the first air inlet 12 and the second air inlet 22 at the same time, thereby expanding the exhaust and sterilization area of ​​the air sterilizer.

[0052] 2) In this embodiment, a rotating device 4 is provided that is connected to the rotating part 24 for transmission. Under the action of the rotating device 4, the second housing 2 rotates relative to the first housing 1 through the rotating part 24 to change the orientation angle of the front of the second housing 2, so that the air sterilizer can adjust the angle of the air inlet according to different environmental conditions, thereby adjusting the exhaust sterilization area.

[0053] 3) In this embodiment, a first isolation lifting curtain device 17 and a second isolation lifting curtain device 26 are provided. When it is necessary to isolate personnel, the isolated personnel are placed under the air sterilizer and the second housing 2 is set to the open state. At the same time, the first isolation curtain 171 and the second isolation curtain 261 on both sides are unfolded, so that a semi-enclosed space is formed under the air sterilizer. Under the action of the exhaust device 111, the semi-enclosed space forms a negative pressure, and the air flow direction is from the outside to the semi-enclosed space, so that the air inside the semi-enclosed space, that is, the aerosol of the isolated personnel, will not diffuse outward, thereby achieving the isolation function.
