The invention provides a T-shaped range hood with multiple
layers of oil fume separation meshes. The T-shaped range hood comprises a housing, an external oil fume separation mesh, a middle oil fume separation mesh, an internal oil fume separation mesh, an oil cup, a motor, a
volute with a motor bracket, double worms, a smog sensor and other range hood assemblies, wherein the external oil fume separation mesh is of an
inverted pyramid shape, the middle oil fume separation mesh is in a plane shape, the internal oil fume separation mesh is in an M shape, and the three oil fume separation meshes form a wrapping progressive space. In light of a principle of fluid dynamics, a huge negative pressure region is generated to collect oil
smoke deeply, the resistance is reduced when the oil fume rises and the exhaust air quantity is increased; the smog sensor senses smog to automatically adjust the motor to rotate so as to adjust the suction of the range hood. The T-shaped range hood sucking and exhausting the oil fume has the functions of quickly sucking the oil
smoke and automatically adjusting
wind power, avoids the risk that the working performance of the range hood is affected as the oil fume is unsmooth to suck and exhaust when the oil fume in the raising process blocks the
smoke meshes, and improves the performance of the T-shaped range hood in the oil fume suction and exhaust.
