The invention relates to a dual-function filter type pot cover, comprising an outside plate, an inside plate, a diverting cover, a filter element and a switching knob, wherein the outside plate, the inside plate and the diverting cover are combined as one, while the switching knob can rotate in relation to the diverting cover, on the inside plate are air vents, on the diverting cover is a separating plate that divide it into a first space with a filter element and a cover plate and a second space with steam holes and an arched guide groove, while on the inner rim of the switching knob is a protruded obstructing plate that is located in the guide groove, so that by rotating the switching knob, when the obstructing plate is away from the steam holes, the steam in the pot will escape without obstruction from the air vent on the inside cover to the first space and out of the steam holes, suitable for cooking food with water, or on the other hand, in case the cooking involves frying with oil, the obstructing plate will obstruct the steam holes, so the oily vapor in the pot may escape from the air vent to the first space, then to the second space, to be filtered by the filter element before clean air is discharged from the air vent on the cover plate.

[ I claim:] [1.] A dual-function filter type pot cover, comprising:an outside plate, which is a main unit or a part thereof, with an assembling opening at its center;an inside plate, on one half of which are air vent holes, which is fixed to the assembling opening of said outside plate;a diverting c
[ I claim:] [1.] A dual-function filter type pot cover, comprising:an outside plate, which is a main unit or a part thereof, with an assembling opening at its center;an inside plate, on one half of which are air vent holes, which is fixed to the assembling opening of said outside plate;a diverting cover, fixed to the assembling opening on the outside plate and in connection with the inside plate, its bottom side being divided by a separating plate into a first space and a second space, the first space communicating directly to the air vent on said inside plate and on its top are steam holes, while the second space accommodating a filter element and being partially communicating with the first space;a switching knob that is mounted on the diverting cover, that will rotate in relation to the diverting cover, on its inner rim at an appropriate location is an obstructing plate, which can be rotated to timely open the steam holes on the diverting cover to allow the water steam in the pot to escape without obstruction from the air vent on the inside plate to the first space and out of the steam holes, or the steam holes can be timely obstructed so the oily vapor could escape from the first space to the second space, then filtered by the filter element before it becomes clean air and comes out of the pot.
