Indoor ventilation system for air purification, sound insulation and noise reduction

Abstract

The invention relates to an indoor ventilation system for air purification, sound insulation and noise reduction. Air pressure balance between two spaces is realized by arranging ventilation grooves in the two spaces. Each ventilation groove comprises a ventilation groove main body, a ventilation channel and an air filtering combination board, wherein the air filtering combination board is arranged in the ventilation groove main body through a magnet, and comprises a filter layer and a sound insulation layer, not only is air filtration realized, but also noise can be reduced. Through the ventilation system, automatic air pressure balance can be realized under the action of the ventilation grooves; the ventilation grooves are internally provided with the air filtering combination boards, when airflow flows between the two spaces, the airflow passing through the ventilation grooves can be filtered, and the effect of sound insulation is achieved to a certain degree; and the air filteringcombination boards are installed through the magnets, installation and dismounting are convenient, and washing and replacement in the later period are both relatively convenient.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to an indoor ventilation system for air purification, sound insulation and noise reduction. Background technique [0002] Doors, windows, etc. are common openable devices in buildings. For the purposes of privacy protection, anti-theft, sound insulation, and heat preservation, doors and windows are installed on buildings, and they have good airtightness after closing. For example, once the doors and windows are closed, the air flow in the building will be poor, which will easily lead to a decline in the air quality in the building for a long time; in addition, good sealing will bring certain difficulties to the opening of the doors and windows. Especially for swing doors and windows, the opening method of such doors and windows is to open to the outside of the building. When the air pressure inside the building is smaller than the air pressure difference outside the...

Problems solved by technology

[0002] Doors, windows, etc. are common openable devices in buildings. For the purposes of privacy protection, anti-theft, sound insulation, and heat preservation, doors and windows are installed on buildings, and they have good airtightness after closing. For example, once the doors and windows are closed, the air flow in the building will be poor, which will easily lead to a decline in the air quality in the building for a long time; in addition, good sealing will bring certain difficulties to the opening of the doors and windows. Especially for swing doors and windows, the opening method of such doors and windows is to open to the outside of the building. When the air pressure inside the building is less than the air pressure difference outside the building and the difference is large, it is more laborious to be affected by the air pressure when opening.
