The bottom of plug-in groove 907 and plug-in part 912 is provided with hard rubber strip 913, and the side of hard rubber strip 913 away from the vertical central axis of front support 3 is provided with plastic curtain three 914, one end of lead screw 902 away from servo motor 901 is rotatably connected with front support 3, the number of fixed block one 904, connecting rod 905 and fixed block two 906 is the same, the side of plastic curtain three 914 away from hard rubber strip 913 is fixedly connected with support frame 2, and sick bed 5 is placed behind plastic curtain three 914.
[0023] Specific operation is as follows, lead screw 902 rotates under the driving of servo motor 901, so that fixed block one 904 moves linearly along the outside of lead screw 902 with lead screw nut 903, thereby driving plug-in groove 907 and plug-in part 912 to slide horizontally towards or away from each other in front support 3 through connecting rod 905, realizing the automatic opening and closing effect of two plastic curtains three 914, without manual pulling to close, improving the use flexibility.
[0024] As Figure 2 and Figure 3As shown, the front end of the fixed block two 906 on the left is provided with a plug-in groove 907, and a sliding groove inside the plug-in groove 907 is provided with a moving plate one 908.

The plug-in part 912 is slidingly arranged in the front support 3, and the internal structure of the plug-in groove 907 is matched with the external structure of the plug-in part 912.
[0025] Specific operation is as follows, in the process of closing two plastic curtain three 914, the plug-in part 912 will be inserted into the plug-in groove 907 to press the moving plate one 908 and the spring 909. The pressing force will act on the pressure sensor 911 through the moving plate two 910. Since the servo motor 901, the pressure sensor 911 and the controller are electrically connected, when the pressure value sensed by the pressure sensor 911 is greater than the threshold value, the controller controls the servo motor 901 to be closed at the first time, so as to ensure that the hard rubber strip 913 is kept close and the isolation effect is better.
[0026] In summary, the ultraviolet laminar bed with automatic closing effect is used. Firstly, the sickbed 5 and the outside air are isolated by two plastic curtain one 7, one plastic curtain two 8, two plastic curtain three 914 and two hard rubber strips 913. Then the air purification device 1 is started. The filtered air is delivered to the sickbed 5 area in a laminar flow manner, so that the sickbed 5 area maintains a positive pressure, preventing external dust and bacteria from entering. At the same time, the ultraviolet lamp 6 sterilizes the sickbed 5 area. After sterilization, the ultraviolet lamp 6 is turned off. Then the patient is placed in the sickbed 5 area.
[0027] When the medical staff needs to enter the sickbed 5 area, the servo motor 901 is started to drive the lead screw 902 to rotate. The fixed block one 904 is driven by the lead screw nut 903 to move along the outside of the lead screw 902 from back to front, so that the rotating connecting rod 905 provides support force for the fixed block two 906. The plug-in groove 907 and the plug-in part 912 slidingly move in the front support 3 in opposite directions, so as to drive the two hard rubber strips 913 to separate, so that the personnel can pass between the two plastic curtain three 914.
[0028] Then the screw rod 902 is rotated under the drive of the servo motor 901, so that the fixed block one 904 follows the screw nut 903 to displace from front to back along the outside of the screw rod 902, thereby the connecting rod 905 is rotated to drive the plug-in groove 907 and the plug-in piece 912 to slide in the front support 3, the plug-in piece 912 is inserted into the plug-in groove 907 and presses the moving plate one 908 and the spring 909, the pressing force is applied to the pressure sensor 911 through the moving plate two 910, when the sensed pressure value is greater than a threshold value, the servo motor 901 stops working according to the control signal sent by the controller, at this time, the two plastic curtain pieces three 914 keep flat, the hard rubber strip 913 keeps close, so that the area of the sickbed 5 is good in sealing performance.
