ABSTRACT:
A novel soot filtering cap in a range hood includes a hood body, a soot absorbing perforated filter and a magnetic strip frame. A hook and loop fastener is provided on the peripheral rim of the vent cap of the hood body. The filter is made of fabric material having strong oil absorbability and strong gas penetrability and is fastened on the peripheral rim of the vent cap of the hood body. A plurality of vent holes are provided on the filter for smooth venting during operation of the range hood, while soot are completely absorbed by the filter. Furthermore, the plane area of the filter is larger than the cross section area of the vent cap and a protective edge is provided on the periphery of the filter. The magnetic strip frame is made of magnetic strip encased with rubber sheath and used to fasten the protective edge of the perforated filter onto the peripheral rim of the vent cap in a manner that facilitates the handling of the perforated filter and assures the positioning of the perforated filter on the peripheral rim of the vent cap.
