Air supply device in elevator and using method thereof

Abstract

The invention discloses an air supply device in an elevator and a using method thereof. The device comprises an elevator car, a ceiling is fixedly installed at the position, close to the top, in the elevator car, and a purification air supply mechanism is arranged at the top of the outer portion of the elevator car. The purification air supply mechanism comprises an air supply box, an air supply flexible hose, an air supply main pipe, an air supply branch pipe, an air inlet flexible hose, an air inlet main pipe, an air inlet branch pipe, a drawer, a handle, an air filter screen, a supporting frame, a fan and a blocking strip. According to the air supply device in the elevator, air supplied into the elevator car can be filtered, passenger health is facilitated, the air direction can be adjusted, the air supply device is suitable for various different use environments and higher in practicability, in addition, when the elevator car operates, an excellent damping effect can be achieved onthe air supply box, the service life of the air supply device is prolonged, meanwhile, noise caused by vibration is reduced, and the use comfort is improved.

Description

technical field [0001] The present invention relates to the field of air supply devices, in particular to an elevator internal air supply device, and more particularly to an elevator internal air supply device and a method for using the same. Background technique [0002] Elevators are usually divided into two categories, one is a car-type vertical elevator, and the other is an escalator-type elevator. The vertical elevator needs to use the air supply device to ventilate the elevator car when it is in use; [0003] However, the existing air supply device in the elevator has certain disadvantages in use. First, it does not have the purification function, and debris such as dust and hair in the air will be sent into the inside of the elevator car through the air supply device, causing the elevator to The air inside the car is polluted, which affects the health of the occupants, and the use effect is poor; secondly, it does not have the function of adjusting the wind direction...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide an air supply device in an elevator, which can effectively solve the problem in the background technology that there is no purification function. Dust, hair and other sundries in the air will be sent into the interior of the elevator car through the air supply device. As a result, the air inside the elevator car is polluted, affecting the health of the occupants, and the use effect is poor; secondly, it does not have the function of adjusting the wind direction. The traditional elevator air supply device only has the air supply function of the outer circulation, does not have the function of the inner circulation, and has low functionality. , not conducive to use in different environments, and the scope of application is small; in addition, it does not have a shock absorption function. When the elevator car is running, it will cause a large vibration force on the air supply device, and the vibration will affect the service life of the air supply device. , it will also produce a lot of noise, which will affect the technical problems of comfort
