Description

Air collection device for air detection

Technical Field

The utility model relates to the technical field of air collection and sampling, in particular to an air collection device for air detection.

Background

The broad sense of air detection refers to the detection of the constituent components of air. The narrow sense of air detection is mainly from the application point of view, and the focus is on indoor air detection. It refers to the substances harmful to human body contained in indoor decoration materials, furniture and the like, and the substances are released into the house and office environment to cause decoration pollution so as to detect the air quality.

Prior to air detection, an air sample needs to be collected using an air sampling collection device. However, when the existing air sample collecting device collects the air sample, the sample air is more or less mixed with the original air in some collecting devices, which is convenient for causing the condition that the accuracy of the air sample is affected during detection and is not high.

the utility model provides an air collection device for air detection, includes miniature air exhauster, gas tube, blast pipe, bottle plug and gas storage bag, bottle plug movable mounting is in the sack department of gas storage bag, has seted up the through-hole that link up the bottle plug from top to bottom on the bottle plug left and right sides two parts respectively, the gas tube passes left through-hole and the lower extreme extends to the interior bottom of gas storage bag, and gas tube movable mounting is in the inboard of left side through-hole, is connected through the air hose between gas tube upper end and the gas outlet of miniature air exhauster, blast pipe fixed mounting is in the inboard of right side through-hole, the sack of gas storage bag is tightly sealed by clamping structure clamp.

As an improvement, the gas storage bag is an opaque silica gel bag.

As an improvement, the clamping structure is a clip. The bag opening of the air storage bag is convenient to clamp and seal.

As an improvement, the bottle stopper is in a round table shape. The bottle plug can be suitable for air storage bags with different diameters of the bag openings in a certain range.

As an improvement, the gas filled tube is a stainless steel tube with a smooth outer surface.

As an improvement, the exhaust pipe penetrates through the right through hole and is positioned on the upper side of the clip.

Compared with the prior art, the utility model has the advantages that: when the air sample is collected, the original gas in the air storage bag is almost completely removed, so that the air sample in the air storage bag is kept, and the collected air sample can hardly contain other irrelevant gases by the sampling mode, so that the accuracy of the air sample detection in the later stage is higher.
