Lift car convenient to ventilate

Abstract

The invention discloses a lift car convenient to ventilate. The lift car comprises a lift car body, a primary ventilation device, a secondary ventilation device, a primary buffer device, a secondary buffer device and a handle device. The primary ventilation device is arranged in the side wall, far away from a door body, of the lift car body. The secondary ventilation device is arranged at the topof the lift car body. The primary buffer device is arranged at the bottom of the lift car body. The secondary buffer device is arranged under the primary buffer device. The handle device is arranged in the lift car body. The primary ventilation device is composed of an air inlet, an air exhauster and a first ventilation mechanism. The lift car has the beneficial effects that a plurality of ventilation devices are arranged, different ventilation methods are adopted according to the number of passenger, the lift car is uniformly ventilated; buffer devices are arranged in and out of the lift car,buffer strength is increased, and uttermost safety of personnel in the lift car is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator cars, in particular to an elevator car that is convenient for ventilation. Background technique [0002] Existing elevator car ventilation is divided into two types: active ventilation and passive ventilation. Regardless of active ventilation or passive ventilation, the common idea is to intake air from the lower part of the side wall of the elevator car and exhaust air from the upper edge of the car. . Adopting the above-mentioned ventilation method can avoid disturbing the passengers in the car by the airflow generated during the ventilation process to the greatest extent, and the airflow will not directly blow on the passengers. But, adopt existing ventilation mode, air flow has greater influence on the passengers standing on the edge of the car, and based on considerations such as safety, people often stand on the above-mentioned position, so that the above-mentioned defects are particularly...

Problems solved by technology

However, the elevators that are currently in service or will be put into use all over the country generally lack safety protection devices.

For the safety of elevators, manufacturers mostly carry out technical improvements from the perspective of controlling elevators to prevent them from falling, but there is a lack of elevators for passengers to save themselves when they fall.
