When an elevator is lifted, an ear blockage phenomenon occurs due to changes of an internal pressure of an elevator car. The internal pressure of the elevator car is changed repeatedly between two different pressure change rates so that a control method inducing passengers' swallow actions can effectively ease the ear blockage phenomenon. However, in existing control methods, the pressure in the elevator car needs to be repeatedly switched to be a positive pressure and a negative pressure relative to the atmospheric pressure in a short time, and problems that a structure of a control device and a control method are complex exist. When the elevator goes down, a positive pressure state in the elevator car is only used to form stair-stepping pressure control in the first half of the running time (TT0). Therefore, the pressure control device only needs to implement switchover once, that is to say, a pressurized state is switched into a pressure reducing state, and the pressure control can be realized.
