The orientation of the surface air hole 79 of the rotating drum 78 is adjusted in real time by changing the rotation state of the rotating drum 78.

[0028] As shown in Figures 8 to 10As shown, the disinfection assembly 8 comprises a storage box 81 fixedly installed at the top end of the support frame 5, and a shunt valve 82 is connected through the bottom end of the storage box 81, and the disinfection assembly 8 further comprises a positioning pipe 83 fixedly installed on the inner wall of the installation box 1, and the positioning pipe 83 is partially in nested contact with another set of sealing rings 710, and a sponge block 84 is installed at the bottom end of the positioning pipe 83, and a plurality of groups of sponge blocks 84 are equidistantly arranged and installed at the bottom end of the positioning pipe 83, and a flow guide pipe 85 is nestedly installed on the inner wall of the positioning pipe 83, and a plurality of groups of drip holes 86 are equidistantly arranged and correspondingly arranged with the plurality of groups of sponge blocks 84, and one end of the flow guide pipe 85 is connected with the shunt valve 82.

[0029] By setting the storage box 81 and the shunt valve 82, the precise pouring of disinfectant alcohol is realized, and by cooperating the positioning pipe 83, the sponge block 84 and the flow guide pipe 85, the disinfectant alcohol is evenly soaked in the sponge block 84 through the drip holes 86 at the bottom end of the flow guide pipe 85, and then naturally volatilizes, so that the incoming ventilation airflow carries the alcohol, and the ventilation airflow forms a mild disinfection atmosphere, which can ensure the ventilation disinfection effect in the infectious disease room while reducing the irritability to the personnel in the infectious disease room.

[0030] As shown in the figure, Figure 11 The closing assembly 9 comprises a motor 91 fixedly installed at the bottom end of the support frame 5, and a rotating rod 92 connected with one end of the motor 91, and a connecting rod 93 sleeved on the surface of one end of the rotating rod 92, and two groups of connecting rods 93 are sleeved on the surface of one end of the rotating rod 92, and a pin shaft 94 is sleeved on the surface of one end of the rotating rod 92, and a rotating plate 95 is fixedly connected with the bottom end of the pin shaft 94, and two groups of rotating plates 95 are rotatably installed at the bottom end of the installation box 1.

[0031] By setting the rotating rod 92, the connecting rod 93 and the pin shaft 94 in linkage, the real-time change of the rotating state of the rotating plate 95 is realized, the rotating plate 95 is opened when the ultraviolet rays are used for disinfection, the disinfection path is not blocked, and the ultraviolet rays are prevented from leaking after being closed, and the use safety is further improved.

[0032] The working principle of the technical scheme provided by the present application is as follows: When the ventilation in the infectious disease room is needed, the personnel situation in the infectious disease room is detected by the infrared sensor 3 first, when there is personnel in the infectious disease room, the infrared data obtained by the infrared sensor 3 is transmitted to the control module 2 through electrical signal, and in this process, the ventilation equipment continuously introduces the ventilation airflow into the air inlet pipe 4. When the infrared sensor 3 detects the presence of personnel in the infectious ward, the control module 2 controls the shunt valve 82 to start, and under the shunt effect of the shunt valve 82, the disinfectant alcohol stored in the storage tank 81 continuously enters the flow guide pipe 85 through the shunt valve 82, and continuously drops through the drop hole 86 on the bottom surface of the flow guide pipe 85. The dropped alcohol enters the sponge block 84 and gathers at the bottom end of the sponge block 84 under the action of gravity, and the alcohol on the bottom surface of the sponge block 84 quickly evaporates due to the porous properties of the sponge block 84. In this process, the ventilation airflow continuously enters the rotating drum 78 through the air inlet pipe 4 and the sleeve 711. Since the positioning pipe 83 and the sponge block 84 are located in the internal cavity of the rotating drum 78, the ventilation airflow entering the rotating drum 78 carries alcohol. Under the action of continuous ventilation, the ventilation airflow carrying alcohol is blown out through the air holes 79 on the surface of the rotating drum 78, and after passing through the dust screen 20, the ventilation airflow carrying alcohol enters the ward, disinfects and ventilates the infectious ward, realizes the ventilation treatment under the condition that there is someone in the infectious ward, and replenishes the alcohol in the storage tank 81 during subsequent maintenance and repair; When the infrared sensor 3 detects that there is no personnel in the infectious ward, the control module 2 controls the shunt valve 82 to close, and then the control module 2 controls the motor one 73 to start. After the motor one 73 starts, the screw rod 72 is synchronously rotated, and under the action of the rotation of the screw rod 72, the piston disc one 74 sleeved with threads on the surface of the screw rod 72 slides and extrudes along the direction of the screw rod 72, continuously extruding the oil liquid stored in the liquid storage barrel 71 into the liquid inlet barrel 75. After the oil liquid enters the liquid inlet barrel 75, it pushes the piston disc two 76 to slide along the inner wall of the liquid inlet barrel 75. The piston disc two 76 slides upward while synchronously driving the rack 77 to slide. The rack 77 slides while engaging with the spur gear 712, causing the spur gear 712 to rotate. The spur gear 712 rotates while synchronously driving the rotating drum 78 to rotate, causing the air holes 79 on the surface of the rotating drum 78 to rotate to the top of the flow guide plate 713. Subsequently, the control module 2 controls the motor two 91 to start. After the motor two 91 starts, the rotating rod 92 is rotated, and one end of the rotating rod 92 drives one end of the two groups of connecting rods 93 to press down. Under the action of the connecting rods 93, the other end of the connecting rods 93 pushes the pin shaft 94 and the rotating plate 95 along a circular trajectory, causing the two groups of rotating plates 95 to synchronously open. Subsequently, the control module 2 controls the ultraviolet disinfection lamp 6 to be turned on, while the ventilation air flow continuously enters the rotating drum 78 through the air inlet pipe 4 and the sleeve 711, and is blown out through the air holes 79 on the surface of the rotating drum 78, so that the air flow blown out through the air holes 79 continuously passes through the surface of the guide plate 713, and the ventilation air flow is continuously decelerated by the shape of the guide plate 713, so that the ventilation air flow is concentrated to pass through the bottom end of the ultraviolet disinfection lamp 6, and the infectious disease room is ventilated, the ventilation air flow passing through the ultraviolet disinfection lamp 6 is continuously disinfected, and the ultraviolet irradiated by the ultraviolet disinfection lamp 6 continuously disinfects the infectious disease room, so that the ventilation of the infectious disease room under the condition of no one is realized.
