Description

Technical Field

[0001] The utility model belongs to the technical field of elevator ventilation and air exchange, and in particular relates to a ventilation and air exchange device for a sightseeing elevator. Background Art

[0002] A sightseeing elevator is a vertical elevator powered by an electric motor, equipped with a box-shaped cabin, used to carry people or goods in multi-story buildings. One or more of the shaft walls and car walls are made of transparent materials, so passengers can see the scenery outside the car while riding the elevator. With the development of the economy, there are more and more types of sightseeing elevators. In order to improve the air quality inside the sightseeing elevator, it is necessary to ventilate the sightseeing elevator through a ventilation device. At the same time, sachets are generally placed inside the sightseeing elevator to reduce the odor inside the sightseeing elevator.

[0003] For example, the patent with publication number CN213011474U discloses a ventilation structure for a sightseeing elevator, including a sightseeing elevator body, one side of the top of the sightseeing elevator body is embedded with an air inlet body, and the other side of the top of the sightseeing elevator body is connected with a first air outlet. When the gas enters the interior of the sightseeing elevator body, the dust in the gas will be filtered when passing through the filter net, and some toxic gases in the air will be adsorbed when passing through the activated carbon net. Clean air is discharged along the ventilation duct through two second air outlets, and a fragrance bag is arranged inside the second air outlet. When the air is discharged through the fragrance bag, a part of the fragrance will be brought out. When the elevator fails, the switch can be turned on, and the backup power supply provides power to the motor to ensure that the motor can continue to drive the exhaust fan to rotate, so that the air inside the elevator body continues to circulate, and fresh air continues to be provided for people inside the elevator body.

[0004] However, in the existing ventilation and air exchange device for sightseeing elevators, it is difficult to replace the sachets used to reduce the odor inside the sightseeing elevators, resulting in a decrease in the fragrance of the sachets and even easy infection by bacteria. In view of this, we propose a ventilation and air exchange device for sightseeing elevators. Utility Model Content
