Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, specifically a building design ventilation structure. Background Technology

[0002] Existing energy-efficient buildings generally have internal ventilation systems. The function of these systems is to promote the exchange and circulation of air between the building and the outside air, meeting the needs of people engaged in various activities. Ventilation is a building environmental control technology that uses methods such as air exchange and dilution or ventilation and exhaust to ensure the quality of indoor and outdoor air environments.

[0003] A search revealed that patent CN219955559U discloses an energy-saving ventilation structure for building design. By rotating two limiting plates 90 degrees to opposite sides, the limiting of the filter screen is removed, allowing the filter screen to be disassembled. The operation is very simple and convenient for quick disassembly and cleaning of the filter screen. The insect-blocking plate can prevent insects from entering the room, and the collection box can be used to collect and dispose of insect carcasses.

[0004] While the above solution can protect the openings at both ends of the air outlet duct from dust and insects by setting up insect screens and filters to prevent dust and insects from entering the building from the outside, the insect screen located on the outside of the building cannot be directly removed from the inside of the building. If the ventilation structure is installed on the second floor or above of the building, it is very inconvenient to maintain the insect screen, and needs to be improved. Utility Model Content
