Description

technical field [0001] The invention belongs to the technical field of elevator equipment, and in particular relates to a suspended ceiling of an elevator car and an elevator car. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, the competition in elevator technology has not only stopped at running speed and safety performance, but people have higher and higher requirements for the comfort of the elevator car. [0003] The existing elevator car is usually equipped with an intake fan on the outside of the car, and an air supply pipe is arranged on the inner wall of the car. The intake fan blows the wind from the air supply pipe to provide ventilation in the car. However, the existing elevator car The box has the following disadvantages: [0004] a. When someone smokes in the elevator car, the smoke cannot escape from the elevator car quickly; [0005] b. In summer or winter, the fresh air coming i...
