Household ventilating fan capable of realizing circulating filtration by utilizing indoor air

Abstract

The invention discloses a household ventilating fan capable of realizing circulating filtration by utilizing indoor air. The fan comprises a wall body, wherein an outer decoration cavity is arranged in the outer side end of the wall body; the inner wall of the outer decoration cavity is communicated with a circulation air cavity; a dust screen is arranged in the circulation air cavity; the inner wall of the circulating air chamber is communicated with a filter cavity; a main air suction fan and a filter cylinder are arranged in the filter cavity; a first inner decoration cavity and a second inner decoration cavity are arranged in the inner side end of the wall body; the inner wall of the first inner decoration cavity is communicated with an air outlet cavity; the inner wall of the second inner decoration cavity is communicated with an air inlet cavity; and an auxiliary air suction fan is arranged in the air inlet cavity. The household ventilating fan disclosed by the invention has theadvantages that a water vapor filter layer, a first filter layer, a second filter layer, a third filter layer and a plant layer are arranged in the filter cylinder to filter the air layer by layer, sothat the air is completely purified, the air quality is improved by a big margin and the indoor environmental quality is increased; and dust in outdoor air is directly filtered through the dust screen to facilitate the further air filtration and improvement carried out by the filter cylinder and facilitate the improvement of air quality.
