Soot filtering cap in a range hood

A soot filtering cap for a range hood having a hood body, comprising

• a plurality of hook and loop fasteners provided on a peripheral rim of a vent cap of said hood body;
• a soot absorbing perforated filter which is made of fabric material having strong oil absorbability and strong gas penetrability and has a plurality of fine vent holes provided on a surface thereof for smoothly venting during operation of said range hood while soot is completely absorbed by said soot absorbing perforated filter so as to achieve an effect of soot removal, wherein said soot absorbing perforated filter has a plane area larger than a cross sectional area of said vent cap of said hood body and forms a protective edge on a periphery thereof, said soot absorbing perforated filter being fastened onto said vent cap of said hood body by means of said hook and loop fasteners and said protective edge of said soot absorbing perforated filter is folded upwardly to cover said peripheral rim of said vent cap of said hood body;
• and
• a magnetic strip frame, which is made of a magnetic strip encased with a rubber sheath, fitly mounted on an outer periphery of said protective edge for sticking said protective edge of said soot absorbing perforated filter onto said peripheral rim of said hood body, thereby said soot absorbing perforated filter not only is fastened on said peripheral rim of said vent cap by said hook and loop fasteners, but also is stuck and positioned magnetically beneath said hood body by said magnetic strip frame in order to prevent said soot absorbing perforated filter from falling off due to heavily absorbing soot and reduction of bonding power between said soot absorbing perforated filter and said hook and loop fasteners and to assure said soot absorbing perforated filter fastening on said peripheral rim of said vent cap and to facilitate soot absorption of said soot absorbing perforated filter.
