Pm2.5 measurement module and range hood with same

A particulate matter (PM) 2.5 measurement module, applied to a range hood, comprising:

• a main body, comprising a frame assembly and a cover assembly, wherein the frame assembly and the cover assembly are connected to form a telescopic inner cavity, and a third measurement hole is provided at a bottom of the frame assembly;
• a telescopic panel assembly, slidably connected in the telescopic inner cavity, wherein a first measurement hole is provided at a top of the telescopic panel assembly, and a second measurement hole is provided at a bottom of the telescopic panel assembly;
• a PM2.5 measurement unit, provided at an installation cavity of the telescopic panel assembly;
• and
• a driving assembly, provided in the telescopic inner cavity, wherein the driving assembly is connected to the telescopic panel assembly and configured to drive the telescopic panel assembly to extend out of or retract into the telescopic inner cavity;
• wherein when the telescopic panel assembly extends out of the telescopic inner cavity, the PM2.5 measurement unit is connected to an outside through the first measurement hole;
• and
• when the telescopic panel assembly is retracted into the telescopic inner cavity, the PM2.5 measurement unit is communicated with the third measurement hole through the second measurement hole, and the third measurement hole is communicated with the outside.
