Abstract
Description
Technical Field
[0001] This utility model relates to the field of exhaust system technology, specifically an elevator air conditioning exhaust system. Background Technology
[0002] Elevator cars need to move vertically up and down within the elevator shaft, so the elevator's exhaust system needs to be carried on the car. To reduce the weight of the exhaust system, the current technology usually involves making a hole in the car and then installing an exhaust fan in the hole. However, this installation method lacks a barrier or filtration structure between the car and the elevator shaft, which can easily cause dust from the elevator shaft to fall into the car, resulting in a lot of dust inside the car.
[0003] According to Chinese patent publication number CN223050152U, an elevator air conditioning exhaust system is disclosed. The second filter is used to filter the air entering the car from the elevator shaft to prevent dust from the elevator shaft from entering the car. The first filter is used to filter the dust discharged from the car and can also catch the dust particles falling from the second filter. When the elevator starts or stops, the dust from the second filter is prevented from falling into the car.
[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The filter structure is set inside the top fixing part of the box, which requires complete disassembly during cleaning. The internal filter is fixed by bolts, which is cumbersome to install and remove. In addition, the filter structure is simple, which reduces the efficiency of the elevator air conditioning exhaust system. Utility Model Content
