Ventilation device of elevator

Abstract

The invention discloses a ventilation device of an elevator. The ventilation device comprises an elevator car vertical shaft and an elevator car, wherein a plurality of vent holes are formed in the side surface of the bottom of the elevator car vertical shaft; a plurality of air outlets are formed in the top of the elevator car vertical shaft; upper air inlets and lower air inlets are formed in the two sides of the elevator car; an air blowing device is mounted on one side of the top of the elevator car; the air blowing device comprises an electric motor, a fan, an activated carbon particle layer and a plurality of blocks of solid air freshening glue; the fan is mounted on the electric motor; the activated carbon particle layer is positioned under the fan; and the solid air freshening glueis positioned in the middle of the activated carbon particle layer. According to the ventilation device, air blown by the air blowing device at the top has an air freshening function, circulation ofair in the elevator car can be maintained at any time, and people taking the elevator have a good mood as air in the elevator car is fresh.

Description

Technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator ventilation device. Background technique [0002] In recent years, the outbreak of infectious diseases has caused the general public to pay more and more attention to disease prevention and treatment. Most of these infectious diseases can be spread through air, contact, droplets, etc. Strengthening physical exercise and reducing going out has reduced the chance of infection to a certain extent. However, as a public place, elevators appear in high-rise buildings in every city. The ventilation situation directly affects the spread of diseases. The development of elevator technology. Major manufacturers are competing on the battlefield of comfort in elevator cars. , The ventilation, temperature and humidity in the car are directly related to the comfort of the ride. The elevator car is like a black box with no windows and no communication with the outside world. It only ...

AI Technical Summary

Problems solved by technology

At present, the national standard does not stipulate the relevant air parameters in the car, so the design of the car cannot refer to the relevant standards. There are various ventilation methods, which may easily cause poor ventilation in the car. On the one hand, it affects the comfort of passengers. Inability to prevent the spread of disease
