Ventilating and noise-reduction device on top of elevator

Abstract

The invention discloses a ventilating and noise-reduction device on the top of an elevator. The ventilating and noise-reduction device on the top of the elevator comprises an elevator car and a sound-insulation material, wherein a vacuum chamber is formed in the right side of the sound-insulation material; an air extractor is welded to the upper part of the right side of the vacuum chamber; an exhaust tube is mounted on the right side of the air extractor; a gas buffering region is arranged on the left side of the exhaust tube; an activated carbon layer is mounted below the gas buffering region; an air suction tube is welded to the right side of the activated carbon layer; a damper is fixedly mounted above the gas buffering region; the middle of the lower part of the damper is connected with a supporting column through a bolt; a gas storage box is arranged on the left side of the supporting column; an aromatherapy layer is laid on the lower part of the gas storage box; a gas outlet is formed in the lower part of the aromatherapy layer; a steel wire rope is mounted in the middle of the upper part of the elevator car; and a driving device is seamlessly welded to the upper part of the steel wire rope. The ventilating and noise-reduction device on the top of the elevator has the characteristics of simple structure, convenience in operation and high practicality.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator top ventilation and noise reduction device. Background technique [0002] With the increasing number of high-rise buildings in our country and the increasing requirements for building automation and intelligence, people have put forward higher requirements for elevator products in terms of performance, quality and quantity. At the same time, the rapid development of the elevator market has promoted the rapid expansion of elevator research and development, production, maintenance services and other related industries. [0003] Due to the lack of ventilation devices in the current elevators, fainting is prone to occur in the elevator, and when the motor drives the elevator to run, it is easy to generate relatively large noise, which requires the equipment of sound insulation materials to reduce the harm of noise to the human body.
