Adapter for a vacuum cleaner

摘要

Owing to the design, the exhaust air of any vacuum cleaner contains very fine dust which is so fine that it is forced through the filter pores together with the exhaust air. Conventional vacuum cleaners blow the exhaust air laden with very fine dust back into the room again. For this purpose, they have large-area slots for reasons of noise damping. Conventional central vacuum-cleaning installations can be installed only at relatively high cost. For someone allergic to dust, however, it is intolerable that the vacuum-cleaner exhaust air loaded with very fine dust is blown back into the dwelling. The adapter offers the possibility of converting conventional vacuum cleaners without great expense such that an exhaust-air hose can be connected. Through the latter, the exhaust air laden with very fine dust can be carried away directly to the outside air, which is highly advantageous especially for those allergic to dust.
