Problems solved by technology

However, due to the lack of consideration in the structural layout of the above-mentioned patents, the mixing density of water and air is not enough, resulting in poor washing effect of oil fumes, and the fan still needs to be cleaned irregularly. In the patent ZL200820145732.X, an additional protective cover is required, which will inevitably increase manufacturing. cost
