【Embodiment】
Elaborate below in conjunction with the accompanying drawings to embodiments of the present invention.
As shown in Figure 1 to Figure 3, a kind of range hood filter screen structure, including set gradually first layer filter screen 1,
Two layers of filter screen 2 and third layer filter screen 3, the first layer filter screen 1 and third layer filter screen 3 are the metal plate with through hole
Net, the second layer filter screen 2 include filtering sponge 22.
First layer filter screen plays first of oil smoke and stops, intercepts, and oil smoke is pre-processed；
Second layer filter screen has good air-flow character, low windage and strong adsorption capacity, not only to air quantity, wind pressure
Influence small, but also the grease in oil smoke is passed through in absorption comprehensively, greatly promotes the grease intercepting efficiency of strainer；When often using one section
Between after the filtering sponge that conveniently can be cleaned or more renewed；
Third layer filter screen does oil smoke last plane collision condensation, further reduce oil smoke enter smoke machine cavity and
Blower interior；
Through actual test, the grease intercepting efficiency of this filter screen can reach more than 60%, than 30% lifting of common oil network
