Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a self-ventilating traction elevator. Background Art

[0002] Traction elevators operate by using an electric motor and a traction sheave to move the elevator car up and down. Specifically, when a passenger presses the elevator button, the elevator control system sends a signal to start the traction motor. The motor converts electrical energy into mechanical energy, using a speed reducer to convert high-speed rotation into low-speed, high-torque output. The speed reducer transmits power to the traction sheave, which begins to rotate, moving the wire rope, thereby driving the elevator car up and down. Traction elevators rely on friction between the wire rope and the rope grooves of the traction sheave to drive the car up and down. This structure allows elevators to withstand heavy loads, making them suitable for high-rise buildings and heavy load applications.

[0003] Traction elevators are widely used in large shopping malls, office buildings and other areas as a means of transportation between floors. However, many times when a large number of passengers step into the elevator car, they often experience chest tightness and shortness of breath, or even dizziness and shock due to poor air circulation inside the car. Moreover, the problems caused by the closed environment in the car are reflected in all aspects. Specifically, the elderly, pregnant women, and children are all people who like to stroll around the mall. However, when entering the traction elevator, first, the poor internal air circulation brings about their own breathing difficulties, second, it is inevitable that there will be body odor among the passengers, and third, if a passenger smokes in the car, the air in the car will be polluted for a long time thereafter. These seem small things, but they have a great impact.

[0004] Based on this, this solution proposes a self-ventilated traction elevator. Utility Model Content

[0005] The purpose of the present utility model is to provide a self-ventilated traction elevator to solve the problems raised in the above background technology.
