[0002] In today's era of rapid globalization, ecological environment and public health security are closely intertwined, becoming a focal point of common concern for all humankind. Bioaerosols, as aggregates of biological particles suspended in the air containing microorganisms, viruses, bacteria, fungal spores, and other biological particles, can not only trigger localized outbreaks of infectious diseases but also have a profound impact on the balance of ecosystems. This urgently necessitates reliable and efficient sampling equipment, leading to the development of temperature-controlled bioaerosol sampling racks.
[0003] Most bioaerosol sampling racks create negative pressure through a connected air pump, causing air carrying bioaerosol particles to flow through the sampling head, where they are captured by the collection medium, thus completing the sampling process.
[0004] In existing technologies, different locations have different requirements for sampling height in complex and variable sampling environments. For example, in hospital wards, in order to accurately capture possible pathogenic aerosols around the bed, the sampling rack needs to be lowered to a height close to the bed, which limits the accuracy and comprehensiveness of the sampling. To address this issue, a bioaerosol sampling rack with temperature control function is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a bioaerosol sampling rack with temperature control function, comprising an outer shell 1, a support column 2 fixedly connected to the bottom of the outer shell 1, the support column 2 ensuring the overall structural stability of the sampling rack, an adjustment mechanism provided at the top of the support column 2, three universal wheels provided at the bottom of the support column 2, a sliding column 21 fixedly connected to the top of the adjustment mechanism, and a collection mechanism provided at the top of the sliding column 21. The outer shell 1 provides physical protection for the internal components, blocking the intrusion of external dust, water vapor and other impurities, and ensuring stable operation of the equipment.
[0025] The adjustment mechanism includes a cylinder 3. The bottom of the cylinder 3 is fixedly connected to the outside of the support column 2. The driving end of the cylinder 3 is fixedly connected to a sliding plate 4. The cylinder 3 is the driving core of the adjustment mechanism. After receiving a control signal, it extends and retracts, driving the sliding plate 4 to move. The outside of the sliding plate 4 is fixedly connected to a rotating shaft 8. The outside of the rotating shaft 8 is rotatably connected to a linkage assembly for pushing.
[0026] The linkage assembly includes two rotating connecting plates 2 and 9. The external parts of rotating connecting plates 2 and 9 are rotatably connected to the outside of the rotating shaft 8. One end of rotating connecting plate 2 and 9 is rotatably connected to rotating connecting plate 1 and 6, respectively, and the other end is rotatably connected to rotating connecting plate 3 and 10. Rotating around the rotating shaft 8, rotating connecting plate 2 and 9 is the key link for force transmission and conversion. The other end of rotating connecting plate 1 and 6 is rotatably connected to a support block 7. One end of rotating connecting plate 1 and 6 is connected to rotating connecting plate 2 and 9, while the other end is fixed to the top of the support column 2 via the support block 7, thus stabilizing the linkage structure. The support block 7 is fixed to the top of the cylinder 3 at the bottom. The other end of the rotating connecting plate 3 10 is rotatably connected to the bottom of the sliding column 21. One end of the rotating connecting plate 3 10 is connected to the rotating connecting plate 2 9, and the other end is rotatably connected to the bottom of the sliding column 21. The rotation of the rotating connecting plate 2 9 is converted into a thrust on the sliding column 21, driving it to rise and fall. The bottom of the sliding column 21 is fixedly connected to the sliding column 1 5. The outside of the sliding column 1 5 is slidably connected to the inside of the sliding plate 4. The support block 7 provides a stable support point for the rotating connecting plate 1 6. The sliding column 1 5 is used to assist the sliding column 21 in stabilizing its rise and fall and prevent it from shaking or deviating.
[0027] Reference Figure 1 , Figure 3 and Figure 4The collection mechanism includes a sample placement box 14, the bottom of which is fixedly connected to the top of the sliding column 21. The sample placement box 14 is equipped with a sample placement assembly, providing space for the internal sample placement assembly, sampler 16, etc., and protecting the sample from external interference. A rotating connecting plate 15 is fixedly connected to the top of the sample placement box 14, and the sampler 16 is fixedly connected to the top of the rotating connecting plate 15. The sample placement assembly includes a sample collection and placement temperature control stage 13, which regulates the temperature to create a suitable living environment for the bioaerosol sample and prevent damage to microbial activity. The external side of the sample collection and placement temperature control stage 13 is fixedly connected to the internal bottom side of the sample placement box 14. An ultraviolet disinfection rod 19 is fixedly connected inside the sample placement box 14 for ultraviolet disinfection. The poison rod 19 disinfects the sample placement space. The sample placement box 14 is equipped with a detection drying hole 20. The rotating connecting plate 3 10 is used to detect the sample humidity or assist in drying to prevent the sample from deteriorating due to excessive moisture. The sample placement box 14 is equipped with a temperature display port 11 on the outside, which displays the internal temperature in real time. The sample placement box 14 is rotatably connected to a glass protective cover 12. The sampler 16 is fixedly connected to a fixing ring 18 on the outside. The sampler 16 is a key piece of equipment for collecting bioaerosols and accurately captures target samples in the air. The fixing ring 18 is slidably connected to a sampling head 17. The sampling head 17 is easy to replace with different types of sampling heads to adapt to different sampling needs. At the same time, the position can be finely adjusted during sampling to optimize the sampling effect.
[0028] Working principle: When height adjustment is required, the cylinder 3 drives the sliding plate 4 to move. The sliding plate 4 is fixed with a rotating shaft 8. When the sliding plate 4 moves, the rotating connecting plate 2 9 will rotate around the rotating shaft 8. Since the two ends of the rotating connecting plate 2 9 are rotatably connected to the rotating connecting plate 1 6 and the rotating connecting plate 3 10 respectively, the other end of the rotating connecting plate 1 6 is fixed to the top of the support column 2 through the support block 7, and the other end of the rotating connecting plate 3 10 is rotatably connected to the bottom of the sliding column 21, the rotation of the rotating connecting plate 2 9 will drive the rotating connecting plate 3 10 to push the sliding column 21 to rise and fall. The sliding column 1 5, which is fixedly connected to the bottom of the sliding column 21, slides inside the sliding plate 4, playing an auxiliary support and guiding role, ensuring that the sliding column 21 can move up and down stably, thereby realizing the adjustment of the height of the acquisition mechanism to adapt to different sampling height requirements.
[0029] Sampler 16 is responsible for collecting bioaerosols. A sampling head 17 is slidably connected to a fixing ring 18 on the outside of sampler 16. The sampling head 17 can collect bioaerosols in the air. Through specific airflow, a built-in small air pump collects air, allowing air containing bioaerosols to enter the sampling head 17 and then be collected inside sampler 16. The temperature control stage 13 inside the sample placement box 14 can control the temperature of the collected samples to maintain their activity and stability. The temperature is sensed by a temperature sensor inside the sample placement box 14, and the temperature is adjusted to the set value by a heating or cooling device. The temperature display port 11 can display the current temperature.
[0030] The sample placement box 14 is equipped with an ultraviolet disinfection rod 19, which can disinfect the collected samples and prevent them from being contaminated. The drying detection hole 20 can be used to detect the dryness of the samples or to perform drying treatment. The glass protective cover 12 can be rotatably connected to the outside of the sample placement box 14. During the sampling process, the glass protective cover 12 can be opened to place or take out the samples. After the sampling is completed, the glass protective cover 12 is closed to protect the samples and prevent external contamination.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
