Abstract

An elevator interior rapid ventilation device comprises an elevator car. The internal top of the elevator car is provided with a box. The front end of the box is provided with a front air inlet. A front draught fan is mounted at the front air inlet. An air outlet is formed in the lower portion of the rear end of the box and connected with the upper end of a vertical air pipe. The lower end of the vertical air pipe is connected with an inlet of an exhaust seat. An outlet of the exhaust seat faces the front portion of the elevator car. A plurality of layers of filter screens are arranged in the box. According to the elevator interior rapid ventilation device, when the elevator car stays on a certain floor and an elevator door is opened, fresh air is sucked in through the front draught fan and filtered through the filter screens; the filtered fresh air passes through the vertical air pipe and then is exhausted through the exhaust seat; accordingly, the ventilation initiative is effectively improved, the ventilation efficiency is improved when the elevator car stays, the air quality in an elevator is effectively improved, and the ventilation speed is increased.

Description

technical field [0001] The invention belongs to the field of elevator engineering, in particular to a quick ventilation device in an elevator. Background technique [0002] The air flow in the car of the elevator is relatively slow, and natural ventilation is performed only by opening and closing the door on the floor, resulting in poor air quality in the car. Contents of the invention [0003] The invention provides a quick ventilation device in an elevator to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] The quick ventilation device in the elevator includes the car, and the box is installed on the top of the car. The front end of the box is provided with a front air inlet, and the front fan is installed at the front air inlet. The upper end of the air duct and the lower end of the vertical air duct are connected to the inlet of the air exhaust seat, and the outlet of the air exhaust se...
