[0092] 1. When the bottle is sent, the staff puts the transmission bottle 5 into the limiting hole 471 of the transfer plate 47 close to the placing opening 44 through the placing opening 44; then the bottle sending program of the workstation 4 is started, the horizontal drive cylinder 473 drives the support plate 46 to slide in the horizontal direction, and the transmission bottle 5 is moved to the lower side of the conveying pipeline 2; then the vertical drive cylinder 474 drives the support plate 46 to move in the vertical direction, so as to drive the transmission bottle 5 to push into the conveying pipeline 2; at the same time, the fan power unit 1 provides driving wind power to drive the transmission bottle 5 to move towards the commutator 3;

[0093] When the magnetic ring 54 at one end of the transport bottle 5 passes through the magnetic induction switch 64, the medicine is sprayed into the conveying pipeline 2 through the atomizing nozzle 63; when the magnetic ring 54 at the other end of the transport bottle 5 passes through the magnetic induction switch 64, the medicine stops being sprayed into the conveying pipeline 2;

8. The hospital pneumatic circulation device with an air disinfection structure inside the pipeline according to claim 1, characterized in that, Both of the solenoid valves (76) are electrically connected to the controller, which is electrically connected to the magnetic induction switch (64).

9. A method for disinfecting air inside hospital pneumatic tube systems, characterized in that, The hospital pneumatic tube system with an air disinfection structure within the duct, as described in any one of claims 1-8, comprises the following steps: Disinfectant solutions with appropriate ingredients are stored in the drug storage module; A response point and a disinfectant spraying point are set on the delivery pipeline connected to the workstation, and a first sensing point and a second sensing point adapted to the response point are set on the transmission bottle. When the first sensing point on the delivery bottle passes the response point, the disinfectant in the medicine storage module is atomized and sprayed into the delivery pipeline. When the second sensor on the delivery bottle passes the response point, the disinfectant spraying stops. The distance between the spray point and the response point is greater than the length of the transfer bottle to avoid the disinfectant being sprayed directly onto the transfer bottle.
