VENTILATION REFLUX TYPE VACUUM CLEANER

摘要

PURPOSE: A ventilation reflux type vacuum cleaner is provided to prevent foreign matters from being dispersed in a suction area, to smoothly suck the foreign matters and to hygienically clean a room. CONSTITUTION: A suction body(300) consists of a suction hole(310) sucking foreign matters and air; a suction passage(320) guiding air into the body of a ventilation reflux type vacuum cleaner with an air inlet(321); and an injection hole(330) injecting reflux air through a reflux passage(40) at the farthest part from the air inlet. The injection hole is place in the opposite side to the air inlet when the air inlet is formed on one side of the suction hole or placed in both sides of the suction hole when the air inlet is formed it the center of the suction hole. In the structure, a suction area and an injection area are surely separated each other so that foreign matters are smoothly sucked without the influence of injection pressure.
