The utility model discloses a theory of operation:
the infrared remote control receiving head 8 is used for receiving an infrared signal transmitted by the remote controller, when a user presses a digital '1' (or '2', '3', '4') key of the remote controller, the singlechip minimum system U1 judges whether the infrared remote control receiving head 8 receives a digital key signal of the remote controller, when a program confirms that the digital '1' (or '2', '3', '4') key transmitted by the infrared remote controller is received, a pin P2.4 (or P2.5, P2.6, P2.7) of the singlechip minimum system U1 sends a low level, and the relay module 7 controls an ultraviolet disinfection lamp 6 corresponding to the layer of drawers 3 to be turned on; meanwhile, a P2.3 pin of a minimum system U1 of the singlechip also sends out low level, and a buzzer J6 is controlled to send out a 'dripping' sound; meanwhile, a pin P1.0 (or P1.2, P1.4 and P1.6) of the minimum system U1 of the single chip microcomputer sends out a low level, and a RED disinfection work indicator light RED corresponding to the layer of drawer 3 is controlled to be lightened through the indicator light module 12. (note: when a certain layer of drawer 3 is not closed or opened, so that the corresponding limit switch 4 is in an opened state, the SCM minimum system U1 prohibits the ultraviolet disinfection lamp 6 of the layer of drawer 3 from being lighted, so as to prevent the ultraviolet rays of the ultraviolet disinfection lamp 6 from damaging the human body. the program processing mode is that the SCM minimum system U1 firstly detects whether the limit switch 4 is in a closed state, namely whether the pin P3.4 (or P3.5, P3.6, P3.7) of the SCM minimum system U1 is at a low level, when the drawer is not closed or opened, the limit switch 4 is in an opened state, namely the pin P3.4 (or P3.5, P3.6, P3.7) of the SCM minimum system U1 is at a high level, even if the keys of numbers '1' (or '2', '3', '4') on the remote controller are pressed, the ultraviolet disinfection lamp 6 corresponding to the layer of drawer will not be lighted, that is, pin P2.4 (or P2.5, P2.6, P2.7) of the minimum system U1 of the mcu sends high. )
In order to simplify the operation, the disinfection time is not required to be set, the disinfection time is internally set to be 1 time and 30 minutes, when the disinfection time is considered to be insufficient, the disinfection can be carried out again, namely, the number '1' (or '2', '3', '4') key on the remote controller is pressed again, and the ultraviolet disinfection lamp 6 is started to work again. When the disinfection time reaches 30 minutes, a pin P1.0 (or P1.2, P1.4 and P1.6) of the minimum system U1 of the singlechip sends out a high level, a RED disinfection work indicator RED in the disinfection cabinet indicator module 12 of No. 1 (or No. 2, No. 3 and No. 4) is turned off, meanwhile, a pin P1.1 (or P1.3, P1.5 and P1.7) of the minimum system U1 of the singlechip sends out a low level, a GREEN disinfection end indicator GREEN in the disinfection cabinet indicator module 12 of No. 1 (or No. 2, No. 3 and No. 4) is turned on, and meanwhile, a pin P2.3 of the minimum system U1 of the singlechip sends out a low level to control the buzzer 6 to send out a 'drop' sound to remind a user that the disinfection time is up. In the disinfection process, if the drawer 3 is pulled open, the limit switch 4 is in an off state, the single chip microcomputer minimum system U1 controls the ultraviolet disinfection lamp 6 to be turned off immediately, and meanwhile, the RED disinfection working indicator lamp RED and the GREEN disinfection ending indicator lamp GREEN in the indicator lamp module 12 are turned off simultaneously to return to the initial state.
