[0002] With increasingly stringent requirements for sample collection and preservation in fields such as environmental monitoring, food safety, and medical testing, the convenience of on-site sampling and the integrity of samples have become paramount. Traditional sampling devices often have limited functionality and cannot meet the demands for rapid sample processing and safe preservation in complex environments. For example, collected liquid samples often require timely cooling to inhibit microbial growth and chemical reactions, but conventional sampling boxes lack active cooling capabilities, making it difficult to guarantee sample quality. Furthermore, the solid-liquid separation process for on-site samples often requires additional equipment and operations, posing a risk of secondary contamination and being cumbersome, thus impacting sampling efficiency.

[0003] Therefore, there is an urgent need for a portable sampling box that integrates multiple functions, enabling rapid cooling and cryogenic preservation of samples, as well as on-site solid-liquid separation, avoiding secondary sample transfer and contamination, and improving the convenience of sampling and the safety of samples.

[0024] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0025] In fields such as environmental monitoring, food testing, medical and health care, and industrial production, on-site sampling is the first and crucial step in analytical testing. Quality control during the sampling process directly affects the accuracy and reliability of subsequent analytical results. Currently, on-site sampling typically relies on general-purpose sampling boxes or insulated containers.

[0026] However, most existing sampling boxes are single-function containers, typically serving only as centralized storage and transportation of various sampling tools (such as sample bottles, gloves, and record sheets). When low-temperature sample preservation is required, operators often simply place ice packs or dry ice into a regular insulated box. This simplistic approach suffers from inaccurate temperature control, uneven temperature distribution within the box, and short insulation time, making it difficult to meet the preservation requirements of temperature-sensitive samples and potentially leading to sample deterioration during transportation.

[0027] Furthermore, existing technologies have significant shortcomings for sampling scenarios requiring on-site solid-liquid separation or filtration (such as suspended solids analysis in water samples). A common practice is for sampling personnel to carry separate filtration devices to the site, perform the filtration in an open environment, and then transfer the filtrate and filter membrane separately into sample vials. This process is cumbersome, and the samples are exposed to the open environment for extended periods, undergoing multiple container transfers, which greatly increases the risk of sample contamination. Simultaneously, carrying multiple, dispersed devices makes on-site operation inconvenient and reduces work efficiency.

[0028] Therefore, there is an urgent need in the field for an integrated sampling device that is highly integrated, fully functional, can effectively protect the original properties of samples, and simplifies on-site operation procedures, in order to overcome the above-mentioned deficiencies of the prior art.

[0029] Based on this, the present invention provides a portable multifunctional sampling box, which, by setting up two functional partitions, an active cooling chamber 2 and an integrated filter chamber 3 that can be opened and closed independently, realizes rapid cooling and low-temperature preservation of samples as well as on-site solid-liquid separation, effectively avoiding secondary transfer and contamination of samples, thereby improving the convenience of sampling and sample safety.
