For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified in conjunction with the accompanying drawings as follows:

when the user cooks the work, the lampblack absorber is used for the oil smoke extraction and the discharge that produce the culinary art in-process to make the air in the kitchen keep clean, avoid the oil smoke to pollute kitchen wall and cupboard, but current lampblack absorber, the during operation, the fan main part of album of bellows starts, and the oil smoke that the extraction user cooks the in-process and produces, when fan main part extraction oil smoke, the oil smoke gets into album of bellows and is discharged from the oil smoke entry. For convenience of explanation, a surface of the range hood aligned with the kitchen range and visible to a user is called a panel, a fume inlet on the panel is called a panel air inlet, a fume inlet on the air collecting box aligned with the panel air inlet is called an air collecting box air inlet, and the panel air inlet and the air collecting box air inlet are consistent with the description herein below. When the fan main part starts, the oil smoke gets into in the collection bellows air intake through the panel air intake, then is discharged from collection bellows under the effect of fan main part, and the part that collection bellows is located fan main part lower extreme is called the wind chamber, and the wind chamber communicates with collection bellows air intake, and the part of collection bellows installation fan main part is called the wind channel section of discharging fume, and fan main part during operation, the oil smoke gets into collection bellows air intake by the panel air intake, then gets into the wind chamber, then discharges out collection bellows under the effect of fan main part. When the range hood works, as the fan body extracts oil smoke, a negative pressure area can be formed near the air inlet of the panel, air in other spaces in a kitchen can be supplemented to the negative pressure area, if the height of the air inlet of the panel is aligned with the head of a user, the supplemented air to the negative pressure area can be inhaled by the user, if the oil smoke extraction effect of the range hood is poor, the oil smoke content in the supplemented air to the negative pressure area is high, and the health of the user can be influenced if the user absorbs too much oil smoke in the long-term cooking process. If the lampblack absorber is when the oil smoke is being extracted, there is air detection device, detects the oil smoke content of air to remind the user to increase the wind-force of lampblack absorber or automatically increase the wind-force of lampblack absorber when oil smoke content is too high, the lampblack absorber can be better to the extraction effect of oil smoke, can avoid the user to inhale too much oil smoke in the long-term culinary art in-process. In order to detect the air quality, an air detection device needs to be installed in the range hood, but in the existing range hood, an electric control device is usually installed on a panel, a glass panel is pasted on the outer surface of the panel, when the electric control device needs to be overhauled, the range hood needs to be dismantled, the maintenance is troublesome, after the range hood is assembled, electric devices are sealed in a shell, and a channel which is specially used for supplying air for an air detection assembly is not arranged on the panel.
