Therefore, fans are generally installed in the elevator to increase the ventilation performance of the elevator. However, when the elevator staff inspect the top of the elevator, the air flow at the top is slow and the ventilation performance is poor. It still feels hot, which is inconvenient for maintenance.

[0003] The existing Chinese patent CN219009642U is an elevator with good ventilation. When solving the above problem, it is necessary to pull the connecting piece to unlock the fan and then turn the fan over as a whole.
