Intelligent dust-removing sterilizing sound-insulating ventilation device for room

The utility model relates to a room intelligent device functioning in aspirating, degerming, soundproofing, breathing and air changing, which is composed of a getter device and an expiring device, wherein the getter device comprises an air suction pipe, at least a section of pipeline and an air outlet. A dust catcher is arranged in the inner side of the nozzle on the lower end of the air suction pipe. A resonance-type silencer is arranged on the upper end of the air suction pipe and the two ends of the pipeline respectively. An impedance silencer, a pipe-type resistance silencer, a slice-type resistance silencer and a blower are arranged in the pipeline. The sidewall of the air suction pipe near the upper end is communicated with the sidewall of the pipeline near one end. The sidewall of the pipeline near the other end is communicated with the air outlet. The expiring device comprises a pumping hole, at least a section of pipeline and a relief tube. The pumping hole has a blower controlled by a controller and an impedance silencer is arranged in the pipeline. The pumping hole is communicated with one end of the pipeline. The sidewall of the pipeline near the other end is communicated with the sidewall of the relief tube. The controller has an infrared sensor. The utility model has the advantages of convenient usage and good effects of aspirating, degerming and soundproofing, and is used for room air changing.
