Air collection device

Abstract

This invention discloses an air collection device suitable for an outdoor air quality detection device. The air collection device includes a main body and a humidity regulator. The main body contains a gas passage and at least one perforation, each perforation communicating with the gas passage; the perforation provides a mounting for an air quality detector, enabling the detector to detect the air quality in the gas passage. The humidity regulator is located in the main body and is used to reduce the humidity of the air in the gas passage.

Claims

1. An air collection device suitable for an outdoor air quality detection device, the air collection device comprising: a body having an internal gas channel and at least one perforation, each of the perforations communicating with the gas channel; the perforations being configured to provide an air quality detector for detecting air quality in the gas channel; and a humidity regulator disposed on the body for reducing the humidity of the air in the gas channel.

2. The air collection device as claimed in claim 1, wherein, The humidity regulator includes a heating unit for increasing the temperature of the gas channel to reduce the humidity of the air in the gas channel.

3. The air collection device as claimed in claim 1, wherein, The main body has a spacer structure, the humidity adjuster is disposed in the spacer structure, the spacer structure divides the gas channel into a first channel, a second channel and a connecting channel, the first channel is connected to the second channel through the connecting channel; the air quality detector is used to measure the gas in the first channel or the second channel.

4. The air collection device as claimed in claim 3, wherein, The body has two air vents, which are respectively connected to the first channel and the second channel.

5. The air collection device as claimed in claim 3, wherein, The body further includes a first structure and a second structure. The first structure includes a receiving groove, and the second structure includes a recess. The spacer structure is disposed on the first structure, and the spacer structure and the receiving groove together form the first channel. The second structure is disposed on the side of the first structure having the receiving groove. The spacer structure and the recess together form the second channel. A portion of the receiving groove and a portion of the recess of the two structures together form the communicating channel.

6. The air collection device as claimed in claim 3, wherein, The humidity regulator includes a heating unit disposed in the spacer structure, the heating unit being used to increase the temperature of the gas channel in order to reduce the air humidity in the gas channel.

7. The air collection device as claimed in claim 1, wherein, The air collection device also includes at least one humidity detector for detecting the air humidity in the gas channel.

8. The air collection device as claimed in claim 6, wherein, The air collection device also includes a temperature sensor for detecting the temperature of the heating unit or the gas passage.
