Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air collection, in particular to a portable device for collecting air quality samples. BACKGROUND ART

[0002] A portable device for collecting air quality samples is a portable device for storing collected air samples. It is a miniaturized tool designed specifically for safely and stably storing air samples, and is suitable for transportation and temporary storage scenarios after on-site sampling. The core function of such devices is to prevent sample contamination, leakage or composition change through physical isolation, environmental control and other methods, so as to ensure the accuracy of analysis results.

[0003] At present, some air sample storage devices on the market have significant limitations when adapting to small vial samples. The internal space design of such devices often tends to standardized specifications, and lacks a refined storage structure for small-volume sample vials, making it difficult to fix small vial samples due to excessive gaps during storage. During carrying, the shaking inside the device may not only cause sample vials to collide with each other, increasing the risk of breakage of glassware, but also cause sample leakage or contamination due to loosening of the sealed bottle cap. CONTENTS OF THE UTILITY MODEL

[0004] To solve various above problems, the utility model provides a portable device for collecting air quality samples that can well fix small air sample vials, is not easy to topple over, and is portable.

[0005] To solve the above technical problems, the technical solution proposed by the utility model is: A portable device for collecting air quality samples, comprising:

[0006] a box body, which is a heat insulation box, a box cover is detachably arranged above the box body, and connecting handles are symmetrically arranged on side walls of the box body;

[0007] storage grooves, which are arranged in the box body in a plurality of numbers, a plurality of partition plates are arranged inside each storage groove, an upper cover is buckled above the storage grooves, positioning strips corresponding to the storage grooves are arranged on an inner wall of the box body, and sliding grooves matched with the positioning strips are arranged on side walls of the storage grooves.

[0008] Further, a vacuum layer is arranged in the side wall of the box body.

[0009] Further, two sides of the box cover are connected and fixed with the side wall of the box body through fixing buckles, and a sealing gasket matched with the box cover is arranged at an edge of an upper wall of the box body.

[0010] Further, the connecting handle is in a D-ring shape, allowing a shoulder strap to pass through.

[0011] Further, a transparent observation window is arranged on an upper wall of the upper cover.

[0012] Further, a lifting strip is fixedly arranged on the side wall of the storage groove.

[0013] Furthermore, the box is also equipped with several placement slots, which are located between the storage slots.

[0014] Compared with existing technologies, the advantages of this invention are as follows: the storage compartment inside the box is equipped with a partition plate, which can precisely divide the space, allowing small air sample vials to be neatly placed in independent areas to prevent them from colliding with each other; combined with the top cover and transparent observation window, it can further secure the sample vials and eliminate the need for frequent opening of the box to check, reducing the risk of sample tipping. At the same time, the design of the positioning strip and sliding groove ensures that the storage compartment is stable inside the box, preventing shaking and displacement.

[0015] The side wall of the enclosure features a rectangular handle that allows for easy hand carrying or shoulder carrying via a shoulder strap, catering to various carrying needs. The overall equipment boasts a compact structure, and the insulated box design and vacuum layer isolate temperature, while the fastening buckles and sealing gaskets ensure airtightness. Balancing practicality and portability, it provides convenience for sample collection. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 A portable air quality sample collection device includes: a box 1, which is an insulated box, and the side wall of the box 1 is provided with a vacuum layer, which can effectively isolate the external temperature, avoid the influence of the external ambient temperature on the air quality sample inside the box, ensure sample stability, and improve sampling quality.

[0024] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4A box cover 2 is detachably arranged above a box body 1, two sides of the box cover 2 are connected and fixed with side walls of the box body 1 through fixing buckles 8, and a sealing gasket 9 matching the box cover 2 is arranged at an edge of an upper wall of the box body 1, which can achieve good sealing, prevent external air, dust and the like from polluting samples, and ensure the purity of the samples.

[0025] with reference to the accompanying Figure 1 and accompanying Figure 2 , connecting handles 3 are symmetrically arranged on the side wall of the box body 1, the connecting handles 3 are in a D-frame shape, which allows a strap to pass through, facilitates connecting the strap for hand carrying or shoulder carrying, and also facilitates directly holding the connecting handles 3 to move the box body.

[0026] with reference to the accompanying Figure 4 and accompanying Figure 5 , a plurality of storage tanks 4 are arranged in the box body 1, positioning strips 7 corresponding to the storage tanks 4 are arranged on the inner wall of the box body 1, and sliding grooves matching the positioning strips 7 are arranged on side walls of the storage tanks 4. Lifting strips 10 are fixedly arranged on the side walls of the storage tanks 4, which facilitates staff to quickly lift the storage tanks 4, and it is easier and more convenient whether taking samples or adjusting the positions of the storage tanks 4.

[0027] with reference to the accompanying Figure 4 and accompanying Figure 5 , a plurality of partition plates 5 are arranged inside the storage tank 4, an upper cover 6 is buckled above the storage tank 4, and a transparent observation window is arranged on an upper wall of the upper cover 6, which is convenient for staff to directly check the quantity and state of samples in the storage tank 4 without opening the upper cover, reduces unnecessary unpacking operations, and avoids samples from being disturbed by the outside.

[0028] with reference to the accompanying Figure 5 , a plurality of placement grooves 11 are also fixedly arranged in the box body 1, the placement grooves 11 are arranged between the storage tanks 4, and can be used for storing refrigeration materials such as ice bags, so as to ensure that air samples are safely stored in a low-temperature environment.
