Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to an elevator exhaust device which is easy to maintain. Background Art
[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment that serve specified floors. It is customary to use elevators as a general term for vertical transportation vehicles in a building regardless of its driving mode. However, in order to keep the air in the elevator car flowing smoothly, an exhaust device is often installed on the top of the elevator bridge.
[0003] Traditionally, when exhausting the elevator box, air is extracted from the elevator box through an air pump. When the exhaust device is used for a long time, a lot of dust will accumulate on the exhaust head, thereby affecting the exhaust effect of the elevator box. However, the existing exhaust head is usually fixed to the top of the elevator bridge top by bolts. Every time the staff disassembles and cleans it, they need to remove multiple bolts one by one, which is cumbersome. At the same time, the existing exhaust device is equipped with a filter box, but the filter plates in the existing filter box are fixedly installed in the box, and the filter plates cannot be conveniently disassembled and replaced. When used for a long time, the box is directly replaced, which greatly increases the cost of use.
[0004] Therefore, it is urgent to provide an elevator exhaust device that is easy to maintain to solve the above problems. Utility Model Content
