3. The elevator sterilization method according to claim 1, wherein: the near-lower end sterilization operation specifically comprises the following steps:
controlling the elevator to move until the lower end of the elevator reaches the nearest position which can be far away from a lower end positioning point;
opening an air passing hole at the lower end of the elevator car, and closing the air passing hole at the upper end of the elevator car;
the sterilizing agent atomizing and spraying mechanism at the lower end of the hoistway of the elevator is controlled to work and spray sterilizing agent to enter the elevator car for sterilization through the air passing hole;
and opening the air passing holes at the upper end and the lower end of the elevator car, controlling the elevator to move to the middle positioning point, and then closing all the air passing holes to finish the near-lower-end sterilization operation.
4. The elevator sterilization method according to claim 1, wherein: the near-middle sterilization operation specifically comprises the following steps:
controlling the elevator to move until the center of the elevator reaches the nearest position which can be far away from the middle positioning point;
judging the movement of the elevator as upward movement or downward movement;
if the sterilizing agent is upwards moved, the air passing hole is closed before moving, the sterilizing agent atomizing and spraying mechanism at the lower end of the hoistway of the elevator is controlled to work and spray the sterilizing agent, the moving operation is carried out after the spraying is finished, and the air passing hole is opened after the moving to the specified position so that the sterilizing agent penetrates through the elevator along with the air flow through the air passing hole to finish the near-middle sterilizing operation;
if the sterilizing agent spraying device moves downwards, the air passing hole is closed before moving, the sterilizing agent atomizing and spraying mechanism at the upper end of the hoistway of the elevator is controlled to work and spray the sterilizing agent, the moving operation is carried out after the spraying is finished, the air passing hole is opened after the moving device moves to the specified position, so that the sterilizing agent penetrates through the elevator along with the air flow through the air passing hole, and the near-middle sterilizing operation is finished.
5. The elevator sterilization method according to claim 1, wherein: the whole-well sterilization and disinfection operation specifically comprises the following steps:
controlling sterilizing agent atomizing and spraying mechanisms at two ends of a hoistway of the elevator to work and continuously spray sterilizing agent;
controlling the elevator to move upwards to an upper end positioning point, then move downwards to a lower end positioning point, and then return to a middle positioning point to stop moving;
and when the elevator moves to the upper end positioning point and the lower end positioning point in the moving process, the air passing holes are opened, and all the air passing holes are closed in other states.
6. The elevator sterilization method according to claim 1, wherein: the quantity relationship of the L1, the L2, the L3, the L4 and the L5 is as follows: l2=0.75L1, L3= L4= L5=0.5L1.
