Personal air cleaning apparatus

A personal air cleaning apparatus comprising:

• a sucking/discharging unit having a suction port for drawing in contaminated air, a discharge port for discharging filtered air, and a filter for filtering contaminants contained in air;
• a filter for outwardly discharging contaminated air received from the sucking/discharging unit;
• a conduit unit for connecting the sucking/discharging unit to the filter;
• and
• a position determining member arranged around the conduit unit and adapted to allow the conduit unit to be bent without being folded, while fixing the position of the sucking/discharging unit, wherein said sucking/discharging unit comprises:
• a suction guide provided with a suction port at one end thereof while being connected to the conduit at the other end thereof;
• a suction port cap mounted to the suction port of the suction guide while having a plurality of suction holes to guide the flow of air introduced therein;
• a discharge guide formed with a discharge port at one end thereof, connected to the conduit unit at the other end thereof, and arranged around the suction guide while being spaced apart from the suction guide by a desired gap to guide the flow of discharged air while having a shape similar to that of the suction guide;
• a U-turn guide mounted to the other end of the discharge guide and adapted to partially return, to the discharge port, contaminated air introduced by the suction guide;
• and
• a filter arranged between the suction guide and the discharge guide and adapted to filter the contaminated air returned by the U-turn guide.

A personal air cleaning apparatus comprising:

• a sucking/discharging unit having a suction port for drawing in contaminated air, and a discharge port for discharging filtered air;
• a filter for outwardly discharging air received from the sucking/discharging unit while supplying clean air via the sucking/discharging unit;
• a conduit unit for connecting the sucking/discharging unit to the filter;
• and
• a position determining member arranged around the conduit unit and adapted to allow the conduit unit to be bent without interrupting air flow therethrough, while fixing the position of the sucking/discharging unit,
• an inner conduit connected at one end thereof to the suction guide while being connected at the other end thereof to a sucking section included in the filter;
• and
• an outer conduit arranged around the inner conduit while defining a passage for clean air in cooperation with the inner conduit, the outer conduit being connected at one end thereof to the discharge guide, and at the other end thereof to a discharge section included in the filter, and wherein
• the conduit has a detachable end structure so as to adjust its length, while having no portion thereof sharply bent through an angle of more than 90°, so as no to interfere with the flow of air.
