Abstract

The invention provides a novel lift car with ventilation and noise reduction functions. The novel lift car comprises a lift car body and further comprises an air inlet and an air outlet which are formed in the lift car body. A ventilation hose is arranged through the air inlet and the air outlet and mounted on a sound isolating layer of the lift car through a sealing piece. The sealing piece comprises a fixed seat arranged at the bottom of the sound isolating layer and further comprises a butting piece and an elastic hoop which are arranged in an assembling groove in the upper portion of the sound isolating layer. A first butting part and a second butting part which are arranged on the sealing piece of the novel lift car are each of a double-butting structure, and thus the sealing effect is better; further, the first butting part deforms under the air pressure effect, the second butting part is extruded by a sealing soft body to be attached to the ventilation hose more closely, the sealing effect is very good, and odors and dust can be prevented from entering the lift car from gaps of the air inlet and the air outlet.

Description

technical field [0001] The invention belongs to the technical field of elevator cars, in particular to a novel car with ventilation and noise reduction. Background technique [0002] When the elevator car is running in the hoistway, the air in the hoistway is compressed, and at the same time, the airflow in the gap between the car and the hoistway will suddenly increase due to the reduction of the flow area, and the speed of the airflow relative to the car will suddenly increase. Wind resistance, these wind resistances not only create resistance to the movement of the car, but also enter from various gaps in the car. In addition to generating wind resistance noise, it will also bring in odors and dust in the shaft, directly affecting the air quality in the car and ride experience. [0003] The ventilation and internal circulation system of the car is an important means to improve the air quality inside the car. When the air intake pipeline is arranged, there is a small gap ...
