Elevator with disinfection function and disinfection method of elevator

The invention discloses an elevator with a disinfection function and a disinfection method of the elevator, and relates to the field of elevators. A solution tank, a high-pressure pump and a disinfection control device are arranged at the top of an elevator car, a spray head is fixed to the bottom of the elevator car, and the solution tank, the high-pressure pump and the spray head are sequentially connected through a pipeline. The disinfection control device is electrically connected with an elevator control device, and the high-pressure pump and a human body sensor fixed to the upper end of the interior of the elevator car are connected with the disinfection control device. After the elevator control device sends out a disinfection preparation instruction and when the human body sensor detects that disinfection conditions are met, the high-pressure pump is started for disinfection, and meanwhile the elevator car is controlled to ascend and descend, so that disinfectant can be evenly dispersed in an elevator
