AI Technical Summary
In existing technologies, the air inlet position of range hoods is fixed and cannot be adjusted according to the height of kitchen utensils and usage, resulting in the range hood being unable to effectively remove fumes from different heights.
Design a lifting air duct structure. Through an electric push rod structure, the air duct can be raised and lowered according to the height of the kitchen utensils. The electric push rod drives the lifting air duct to adjust the height of the side air inlet, ensuring that the range hood can effectively absorb oil fumes from different heights.
The range hood can be adjusted according to the height of the cookware and the height of the oil fume release. The side air inlet position ensures that the air intake is close to the source of oil fumes, which improves the suction effect and enhances the suction efficiency of the range hood.
