Beschreibung
Zusammenfassung:	The present invention relates to a blower pipe for an air circulator. In particular, the present invention relates to a blower pipe for an air circulator, which consists of an inner blower pipe and an outer blower pipe, and is capable of reducing air circulator noise in various frequency bands, especially low frequency bands. The inner blower pipe and the outer blower pipe are spaced apart from each other by a spacer plate or a spacing pillar, and a through hole or resonance hole communicating with the outer blower pipe is formed in the deep part of the inner blower pipe. 본 발명은 공기순환기용 송풍관에 관한 것으로, 특히 송풍내관과 송풍외관으로 구성되고 그 사이에서 다양한 주파수 대역 특히 저주파 대역의 공기순환기 소음을 감소시킬 수 있는 공기순환기용 송풍관에 관한 것이다.
