In a configuration that meets the requirements, an end that is in the air inlet side of gas channel has a guide ring of expanding at least gradually towards the air inlet side direction.Guide ring itself cross a main air intake, in the running, enter gas channel by blowing impeller inhaled air by main air intake.Guide ring relative wind passage is to arrange like this, forms the ring-type air inlet of a broad between guide ring and gas channel.The notion of " an additional ring-type air inlet " in the scope of this embodiment that this additional air inlet is formed by the inner surface and the guide ring outer surface of gas channel tube wall can be understood as the structure that an air inlet or each air inlet are formed.When the device running, the additional air flow that it will cause surrounding the primary air that passes guide ring enters into gas channel.
Conform with the destination, the longitudinal axis of guide ring and gas channel is arranged with one heart, wherein is designed in one embodiment: this gas channel is made of a tubular part, and its internal fixation has one in order to drive the required motor of blowing impeller.
In a favourable configuration, be constituted as with its cylindrical sector and extend in the gas channel, so that the additional air flow that the air inlet by ring-type sucks can produce certain deflection, and this causes that in vertical section of gas channel second air-flow enters into this gas channel.
Guide ring is curved the funnel shaped that opens mouthful to the air inlet side, and like this from being particularly advantageous for reducing running noise, and this section has straight part equally, therefore formed the profile of a truncated cone.This section can be connected on the cylindrical sector again, and the latter inserts in the gas channel as described above.Minimum in order running noise to be reduced to, bending section also will connect another section at air inlet side place, this section have on the contrary to curvature, wherein this curvature reaches such degree, has promptly avoided reducing again of the inner air inlet clear span of guide ring.The S-shaped bending in the longitudinal section of this guide ring is satiable.
Guide ring for example can be fixed in the support on the parts that constitute gas channel by insertion.
