Abstract

The invention discloses a range hood combined with mobile photographing equipment. The range hood is equipped with a range hood main body, a harmful substance detecting device for analysing an oily fume picture and detecting a temperature in a cooking area, an oily fume size, particulate matter concentration and polycyclic aromatic hydrocarbon concentration, and the mobile photographing equipmentfor acquiring the oily fume picture of the cooking area, wherein the harmful substance detecting device is electrically connected to the range hood main body; and the mobile photographing equipment isin signal connection to the harmful substance detecting device. The range hood can be combined with the mobile photographing equipment for use, so that the temperature in the cooking area, the oil fume size, PM2.5 concentration, PM10 concentration and polycyclic aromatic hydrocarbon concentration are detected, and health grading further can be performed according to particle matter concentration,polycyclic aromatic hydrocarbon concentration and volatile organic compound concentration. The range hood is further provided with an air speed control module, a prompting module and a fire control module, and air speed and firepower of an external stove are automatically regulated according to the health grade of the current environment, so that harmful substance concentration of the current environment is reduced, and a user is reminded to pay attention to protection.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood combined with a mobile photographing device. Background technique [0002] In modern life, many families produce a lot of cooking fume. Studies have shown that cooking fume has complex components, has certain inhalation toxicity, immunotoxicity and mutagenicity, and has certain hazards to human health. The fume gas includes polycyclic aromatic hydrocarbons and various particulate matter. A considerable part of the polycyclic aromatic hydrocarbons is carcinogenic, such as benzo[α]pyrene. The particulate matter has varying degrees of impact on the human respiratory system. The range hood in the prior art cannot automatically identify the concentration of polycyclic aromatic hydrocarbons in the range hood in the current cooking environment, which greatly limits the intelligent development of the range hood. [0003] Therefore aiming at the deficiencies in the prior art, it ...
