The invention discloses a range hood control method and a range hood; the method comprises the following steps: obtaining the first lip image information of a target; using the first model to analyzethe first lip image information, determining the first identification content corresponding to the first lip image information, wherein the first model is obtained by using a plurality of data sets for machine learning training, each the data set comprises the lip image information and the content corresponding to the lip image information; forming the first control order according to the first identification content; controlling the range hood to execute motions corresponding to the first control order according to the first control order. An existing range hood needs manual operations in work, thus reducing the user usage experiences; the range hood control method and the range hood can solve said problems.
