In an embodiment, the stamping depth of the first press mold 112 is greater than or equal to the stamping depth of the second press mold 113, that is, the width of the second press mold main body 1131 protruding out of the first press mold main body 1121 is smaller than the width of the first press mold 112 protruding out of the back plate main body 111, so that waste oil attached to the second press mold main body 1131 can drop into the second press mold 113, the drainage effect of the waste oil is improved, and the problem that the waste oil on the second press mold main body 1131, caused by the fact that the second press mold main body 1131 directly protrudes out of the back plate main body 111, directly drops down to the bottom of the fume collecting hood 1 is avoided.

In an embodiment, the distance between two adjacent second profiling 113 is equal, so as to facilitate the processing of the back plate 11, and improve the appearance aesthetics of the fume collecting hood 1 and the range hood. In other embodiments, the spacing between portions of adjacent second profiling 113 may not be equal.

The length of the second profiling 113 in the left-right direction is preferably greater than 50mm and less than 120mm, in order to avoid that the second profiling 113 is too small, which leads to an increase in the number of second profiling 113 required, while also avoiding the problem that the length of the second profiling 113 is too large, which leads to a smaller number of second profiling 113 that can be provided. The number of the second profiling 113 is preferably 3 to 5, so that the problem that the cleaning difficulty is increased due to the excessive number of the second profiling 113 is avoided.

In an embodiment, the inner wall surface of the fume collecting hood 1 is provided with an oleophobic coating so as to reduce the adhesion of grease in the fume collecting hood 1 and further improve the cleaning convenience of the fume collecting hood 1.
