Specifically, the safety detection unit 302 is connected to the MCU control module 301, and is used to detect whether a person or animal enters the elevator or is at the door of the elevator in the state of opening the door of the elevator when the sterilization assembly 400 performs sterilization. The duration setting module 303 is connected with the MCU control module 301, and the duration setting module 303 is used for setting the timing duration of the disinfection timing module 304 and the waiting timing module 305. The disinfection timing module 304 is connected with the MCU control module 301, and the disinfection timing module 304 is used for calculating the disinfection duration of the disinfection assembly 400 and sending a control signal to the MCU control module 301 after the duration is reached so as to control the elevator button sterilizer to enter a sleep state. The waiting time module 305 is connected with the MCU control module 301, and the waiting time module 305 is used for calculating the duration that the first sensing unit 500 and the second sensing unit 320 do not sense the human or animal in the sensing area, and sending a control signal to the MCU control module 301 after the duration is reached, so as to control the elevator button sterilizer to enter a sleep state. The time adjustment module 306 is connected to the MCU control module 301, and the time adjustment module 306 is configured to adjust the calculated duration of the disinfection timer module 304 after the disinfection module 400 is broken during operation.
It should be noted that, after the first sensing unit 500 senses that the person uses the elevator button, the sensing signal is sent to the MCU control module 301, so that the MCU control module 301 controls the elevator button sterilizer to enter the working state in a sleep state, then, when the second sensing unit 320 and the first sensing unit 500 sense that no person takes in the elevator car, the sensing signal is sent to the MCU control module 301, the MCU control module 301 controls the sterilizing component 400 to perform the sterilizing operation, meanwhile, the sterilizing timing module 304 is controlled to perform the timing of the sterilizing duration, and after the sterilizing timing module 304 reaches the sterilizing duration, the MCU controls the elevator button sterilizer to enter the sleep state again. When the safety detection unit 302 senses that a person enters the sterilization area of the sterilization assembly 400, the sterilization assembly 400 is controlled to suspend sterilization, and at the same time, the sterilization timing module 304 suspends timing, and then the sterilization assembly 400 and the sterilization timing module 304 are controlled by the time adjustment module 306.

S3, sensing the respective sensing areas through the first sensing unit 500 and the second sensing unit 320, when the first sensing unit 500 and the second sensing unit 320 do not sense a person or an animal, the MCU control module 301 controls the sterilization assembly 400 to perform sterilization and disinfection operation, meanwhile, the sterilization timing module 304 enters a timing stage, and after the sterilization timing module 304 reaches a sterilization time period, a control signal is sent to the MCU control module 301 to control the elevator button sterilizer to enter a sleep state; otherwise, the waiting-in-time module automatically enters a timing stage and sends a control signal to the MCU control module 301 after the arrival time to control the elevator button sterilizer to enter a sleep state.
Further, during sterilization of the sterilization assembly 400, S3 includes the steps of:
S31, detecting a detection area through a safety detection unit 302, when the safety detection unit 302 detects a person or an animal, controlling a disinfection assembly 400 to pause the disinfection operation by an MCU control unit, otherwise, enabling a MCU control unit disinfection timing module 304 to enter a timing stage, and sending a control signal to the MCU control module 301 after reaching a time length so as to control an elevator button sterilizer to enter a sleep state;
S32, after the disinfection assembly 400 pauses disinfection, the time adjustment module 306 counts the pause time, and adjusts the disinfection timing module 304 according to the timing condition of the pause time so as to enable the disinfection assembly 400 to achieve the disinfection effect;
S33, when the timing condition of the pause time reaches the preset time in the time adjustment module 306, the time adjustment module 306 controls the disinfection timing module 304 to reenter the timing stage and simultaneously controls the disinfection assembly 400 to disinfect and sterilize the elevator keys again; when the timing condition of the pause duration does not reach the preset duration in the time adjustment module 306, the time adjustment module 306 controls the disinfection module 400 to continue disinfecting the elevator keys while controlling the disinfection timing module 304 to continue timing.
By adopting the method, the disinfection effect of the elevator button can be improved, the elevator button can be timely disinfected after being used, meanwhile, the disinfection assembly 400 can be timely suspended when the elevator is opened, people taking the elevator can safely enter and exit the elevator, and the elevator disinfection device has the advantages of good disinfection effect, simplicity and convenience in disinfection operation and high safety coefficient.
