The disinfection method of the split dry-hot air disinfection device in the embodiment of the invention is characterized by comprising the following steps:

s1, rotating the handle 1-7 of the file cabinet to open the cabinet door 1-4, and putting the medical records on the transverse partition board 1-6 in the file cabinet. And (3) turning on a system switch 2-7 to electrify the heating bin positioning electromagnet 2-19-2, wherein the file cabinet guiding and positioning module 1-10 and the heating bin guiding and positioning module 2-19 are connected to form a complete electric loop, so that the file cabinet guiding and positioning module 1-10 has no electric shock danger at the moment, but the part of the heating bin guiding and positioning hole 2-19-1 and the heating bin guiding and positioning needle 2-19-3 which is not coated with insulating paint is prevented from being touched by hands, and the electric shock is prevented. A worker holds the transportation handrails 1-3 by hand to push thefile cabinet 1 onto the heating bin floors 2-15, and since the file cabinet guiding and positioning seats 1-10-3 are made of metal magnetic materials, when thefile cabinet 1 and theheating bin 2 are close to each other, the heating bin positioning electromagnets 2-19-2 can attract and guide the file cabinet guiding and positioning seats 1-10-3, and the worker is helped to align the file cabinet guiding and positioning modules 1-10 and the heating bin guiding and positioning modules 2-19. Until the file cabinet guiding and positioning needle 1-10-2 is just clamped into the heating bin guiding and positioning hole 2-19-1, the file cabinet guiding and positioning module 1-10 is tightly connected with the heating bin guiding and positioning module 2-19, the male head 1-11 is tightly connected with the female head 2-16, and thefile cabinet 1 is communicated with theheating bin 2 through air; at the moment, the communication indicator lamp 2-20-1 is long and bright, which indicates that thefile cabinet 1 and theheating chamber 2 are successfully connected, and the disinfection work can be started.

S2, setting the disinfection time and the disinfection temperature on the operation panel 2-8 by the staff, after confirming that the work is started, operating the indicator lamp 2-20-2 to be normally on, controlling the heating pipe 2-13-2 to start heating, operating the heat exchange fan 2-4, and exhausting air upwards to accelerate the heat dissipation of the heating pipe 2-13-2, so that the air in theheating bin 1 is uniformly heated as soon as possible. The two circulation fans 2-5, which are opposite in direction, ensure good air fluidity inside thefile cabinet 1 and theheating compartment 2, so that the air inside thefile cabinet 1 and theheating compartment 2 quickly and uniformly reaches a predetermined disinfection temperature.

When the real-time temperature detected by the temperature sensor 2-12 reaches the preset disinfection temperature, a signal is transmitted to the controller in the operation panel 2-8, and the controller controls the power of the heating pipe 2-13-2 to be reduced. When the real-time temperature detected by the temperature sensor 2-12 is lower than the preset temperature, a signal is transmitted to a controller in the operation panel 2-8, and the controller controls the power of the heating pipe 2-13-2 to be increased. The air temperature in thefile cabinet 1 and theheating bin 2 is kept constant by controlling the power of the heating pipes 2-13-2.

When the pressure sensor 2-11 detects that the pressure in theheating bin 2 is overhigh, a signal is transmitted to the controller in the operation panel 2-8, and the controller opens the electromagnetic valve 2-17 of the heat dissipation air outlet fan, so that high-pressure air in theheating bin 2 flows out, and the pressure in the bin is reduced. When the pressure sensors 2-11 detect that the pressure in theheating chamber 2 returns to normal, a signal is transmitted to the controller in the operation panel 2-8, the controller closes the electromagnetic valves 2-17 of the heat dissipation air outlet fan, and the closed state of theheating chamber 1 is restored. If the pressure in theheating bin 2 is too high, the electromagnetic valves 2-17 of the heat-dissipation air-out fans are failed or cannot be opened due to other reasons, and when the pressure in the bin reaches the working pressure of the file cabinet pressure relief valves 1-8, the file cabinet pressure relief valves 1-8 are opened, so that high-pressure air in thefile cabinet 1 and theheating bin 2 flows out, and the pressure in the bin is reduced. And when the pressure in the bin is lower than the working pressure of the file cabinet pressure relief valves 1-8, the file cabinet pressure relief valves 1-8 are closed. The file cabinet pressure release valves 1-8 are mechanical pressure release valves, so that the failure probability is low and the safety coefficient is high; more levels of protective safety devices may be provided.

S3, after the set disinfection time is reached, thefile cabinet 1 is only required to be far away from theheating bin 2, the connection between the male head 1-11 and the female head 2-16 is released, the guide column 2-16-4 seals the central through hole through the annular sealing ring under the action of the return spring 2-16-2, and the vent hole 2-16-5 is sealed by the air hole plug 2-16-6, so that theheating bin 2 is in a closed state.

S4, if a plurality offile cabinets 1 need to be disinfected continuously, after the disinfection time of thefirst file cabinet 1 reaches a preset time, the staff can choose not to lower the temperature on the operation panel 2-8. The controller cuts off the power of the heating bin positioning electromagnet 2-19-2, the communicated indicator lamp 2-20-1 is turned off, the heating pipe 2-13-2 stops heating, the heat exchange fan 2-4 stops, and the circulating fan 2-5 stops.

And then, the operator selects the next file on the operation panel 2-8, the controller energizes the heating bin positioning electromagnet 2-19-2, the operator pushesother file cabinets 1 to be disinfected, and the steps S1-S3 are repeated, so that thenext file cabinet 1 can be disinfected.

Because the male heads 1-11 are not totally closed, the hot air in thefile cabinet 1 can exchange heat with the outside air from the gaps of the male heads 1-11 to dissipate heat, thefile cabinet 1 does not have a heating device, and after the file cabinet is separated from a heating bin, the file cabinet can be cooled slowly by self without supervision of personnel, so that the safety is guaranteed. And generally, the operation is carried out, and the emergent articles cannot be taken out for disinfection, so that thefile cabinet 1 does not have the necessity of rapid cooling under the normal condition; if thefile cabinets 1 need to be rapidly cooled, a cooling fan is installed on eachfile cabinet 1.

If thefile cabinet 1 does not need to be disinfected continuously, after disinfection is finished, a worker can select to start cooling on the operation panel 2-8, the controller controls the heating pipe 2-13-2 to stop heating, the controller opens the heat dissipation air outlet fan electromagnetic valve 2-17 and the heat dissipation air inlet fan electromagnetic valve 2-18, meanwhile, the heat dissipation air inlet fan 2-2 and the heat dissipation air outlet fan 2-6 work to respectively suck cold air and discharge hot air into theheating bin 2, when the temperature sensor 2-12 detects that the real-time temperature is unchanged within 5min, a signal is transmitted to the controller, the controller controls the heat dissipation air inlet fan 2-2 and the heat dissipation air outlet fan 2-6 to stop working, cooling is finished, and the system switch 2-7 is closed.

When eachfile cabinet 1 reaches the set disinfection time, the operation indicator lamp 2-20-2 flickers, and a worker can confirm whether to start cooling on the operation panel 2-8. If thenext file cabinet 1 does not need to be disinfected continuously, the staff can choose to start cooling, the controller controls the heating pipe 2-13-2 to stop heating, the controller opens the electromagnetic valve 2-17 of the heat dissipation air outlet fan and the electromagnetic valve 2-18 of the heat dissipation air inlet fan, and simultaneously the heat dissipation air inlet fan 2-2 and the heat dissipation air outlet fan 2-6 work to respectively suck cold air and discharge hot air into theheating bin 2. Because the heat exchange fans 2-4 and the circulating fans 2-5 are always operated, the temperature in theheating bin 2 and the temperature in thefile cabinet 1 can be quickly reduced. When the temperature sensor 2-12 detects that the real-time temperature is unchanged within 5min, a signal is transmitted to the controller, the controller controls the heat dissipation air inlet fan 2-2 and the heat dissipation air outlet fan 2-6 to stop working, the heat exchange fan 2-4 and the circulating fan 2-5 to stop working, the heat dissipation air outlet fan electromagnetic valve 2-17 and the heat dissipation air inlet fan electromagnetic valve 2-18 are closed, the end indicator light 2-20-3 is lightened, and the operation indicator light 2-20-2 is extinguished. The controller cuts off the power of the heating bin positioning electromagnet 2-19-2 and the communicated indicator light 2-20-1 is turned off. At this time, the worker can hold the transportation handrails 1-3 by hand to pull thefile cabinet 1 away from the heating chamber floors 2-15. The handle 1-7 of the file cabinet is rotated to open the cabinet door 1-4, and the medical records are taken out to complete one-time disinfection operation. The system switch 2-7 can be pressed to turn off the device for a longer time without the need for sterilization. When the disinfection operation needs to be carried out again, the system switch 2-7 is pressed to turn on the device.

Theheating bin 2 needs accelerated heat dissipation because the heating source is arranged, and the accelerated heat dissipation can protect theheating bin 2; under general conditions, the shutdown waiting time of a user can be greatly shortened due to the fact that a special person takes care of or at least sets up warning reminding before theheating chamber 2 is not cooled, and safety and use efficiency are improved.

The disinfection temperature of theheating chamber 2 in the embodiment of the invention can be adjusted within the range of 40-120 ℃, and the disinfection time can be adjusted within the range of 10-120 min; in the disinfection process, if the controller receives faults of overhigh real-time temperature, overlow temperature and the like sent by the temperature sensors 2-12, the alarm indicator lamps 2-20-4 are controlled to flash to give an alarm. Optionally, a buzzer is provided, and the buzzer simultaneously gives out a buzzing alarm. When a fault or a bad state occurs, the emergency stop button 2-10 can be pressed to stop working emergently for follow-up inspection and maintenance.
