[0002] Freight elevator, as the name implies, is a lifting device used to transport goods or people vertically. It is widely used in factories, warehouses, shopping centers, hospitals, docks, stadiums and other places where goods need to be lifted. Freight elevators can be divided into: freight elevators, car elevators, utility elevators, hydraulic freight elevators, scissor-type freight elevators, rail-type lifting freight elevators, etc., among which the freight elevator ventilation device is an important component of the freight elevator. Its main function is to ensure the internal air circulation of the freight elevator, prevent the air from being polluted or the humidity from being too high due to long-term closure, so as to maintain the comfort of the internal environment of the freight elevator and the normal operation of the equipment. Freight elevator ventilation devices usually consist of vents, fans or blowers and related pipes. Ventilators are generally set at the top or side of the freight elevator so that fresh air can enter the interior of the freight elevator. Fans or blowers are responsible for extracting the air inside the freight elevator to form air convection and maintain air circulation. Related pipes are used to connect the vents and fans or blowers to form a complete ventilation system.
