A kind of elevator with convenient and automatic adjustment of air volume

Abstract

The invention discloses an elevator for convenient and automatic air volume adjustment, which comprises an elevator outer shell, an elevator inner shell, a pulley seat and pulleys, an elevator inner shell is installed inside the elevator outer shell, an elevator outer shell and an elevator inner shell Ventilation channels are provided between the bodies, and a plurality of projections are arranged at equal intervals at the bottom of the inner casing of the elevator, and slide grooves are provided on both sides of the inner casing of the elevator above the projections. The invention drives the pulley to rotate when the elevator rises and falls, and uses the rotation of the pulley to drive the rotation of the first blade and the second blade, so that the outside air is introduced into the elevator and the elevator's internal air is introduced into the outside, thereby improving the circulation of the air inside the elevator , and can change the ventilation volume of the elevator car according to the number of passengers in the elevator car, improve the air quality of the elevator car, and at the same time filter the dust in the air entering the elevator, and the air entering the elevator can drive the third The fan blade rotates to make the brush on the second rotating shaft clean the dust on the dust filter net.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator that can conveniently and automatically adjust the air volume. Background technique [0002] In recent years, with the development of high-rise buildings, the use of elevators has become one of the indispensable equipment for people. Its main function is to transport passengers at vertical heights. Running speed and safety performance are two important performance indicators of elevators. However, with the development of the economy and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort and air quality of the elevator car, so the ventilation device inside the car is particularly important. [0003] The interior of the traditional elevator car is generally equipped with ventilation holes, and some elevator cars are ventilated by means of exhaust fans to avoid the possibility of suffocation caused by the...

Problems solved by technology

[0003] The interior of the traditional elevator car is generally equipped with ventilation holes, and some elevator cars are ventilated by means of exhaust fans to avoid the possibility of suffocation caused by the lack of air circulation when passengers take the elevator. In the internal ventilation of the elevator car, the air volume cannot be changed according to the number of passengers and the weight of the elevator car, so that when there are many people in the elevator car, it cannot meet the ventilation requirements for a large number of people, and it is inconvenient to use
