Problems solved by technology

Therefore, the external side flow path needs to have a length corresponding to the provision of two external air introduction parts, and the length of the exhaust path increases, resulting in a complicated structure of the exhaust path.
In addition, if the length of the external flow path portion is increased, it needs to be arranged so as to avoid interference with other components, which may lead to adjustment of the arrangement position and complexity of the support structure.
