Description

Technical Field

[0001] The utility model belongs to the technical field of elevator ventilation, and particularly relates to an elevator environmental protection ventilation system. Background Art

[0002] An elevator is a fixed lifting device that serves specified floors. Due to its special structure, the elevator car is often a relatively sealed cavity with poor air circulation. When the passenger load is large, the stuffiness in the elevator car is particularly obvious, so air supply equipment is often installed in the elevator car; however, there are still some problems with the environmentally friendly ventilation structure of elevators in the prior art. For example, a filter is generally installed at the air inlet duct of the elevator fan. Although the filter can prevent dust from entering the elevator bridge box with the fan, over time, the mesh of the filter will gradually be clogged with dust, affecting the ventilation effect. Since the air inlet duct is usually installed at the top of the elevator bridge box, the top plate needs to be removed when the filter is replaced, which makes disassembly and assembly difficult.
