Description

Technical Field

[0001] This invention relates to the field of pathogen detection and sampling technology, specifically a rapid detection and sampling toolkit for yak brucellosis. Background Technology

[0002] As the core livestock of the Qinghai-Tibet Plateau and surrounding high-altitude areas, yaks are an important source of income for local herders, possessing multiple values ​​including meat, milk, wool, and draft power. They play an irreplaceable role in maintaining the plateau's ecology and people's livelihoods. However, yak farming has long been threatened by brucellosis, a zoonotic infectious disease caused by Brucella bacteria. Brucellosis is highly pathogenic to yaks, causing miscarriage and stillbirth in pregnant yaks, orchitis in male yaks, decreased immunity and stunted growth in adult yaks, and a significantly reduced survival rate for calves. This results in huge economic losses to the plateau livestock industry every year. Even more seriously, brucellosis can be transmitted to humans through the blood, secretions, and excrement of infected animals. Therefore, testing for brucellosis in yaks has become an essential need for the industry. Rapid testing for brucellosis in yaks requires various testing tools, necessitating the use of a testing and sampling toolbox for carrying these tools.

[0003] However, the existing detection and sampling toolkits still have certain shortcomings in use; A livestock quarantine toolbox, as proposed in application number CN202022341285.9, mainly includes a box body with an item placement cavity for storing quarantine items; a lid rotatably mounted on the box body with a platform placement cavity for storing a quarantine platform assembly; and the quarantine platform assembly, which is foldable within the platform placement cavity and can be pulled out and unfolded to form a quarantine platform. This foldable assembly allows for easy quarantine operations by personnel. Additionally, an item placement slot can be provided on the quarantine platform for storing quarantine supplies. However, in practical use, the following problems still exist: The toolbox adopts a split structure of "box body (item placement chamber) + box cover (platform placement chamber)". Quarantine supplies and quarantine platform components are stored in different chambers. During sampling, tools and platforms need to be retrieved from the box body and box cover respectively. There is no integrated linkage opening and closing mechanism, which results in tools being scattered and cumbersome retrieval steps. In addition, the toolbox does not integrate a disinfection device, so it cannot disinfect waste generated during the sampling process (such as sampling needles, contaminated dressings, etc.), which reduces its practicality. Its structure lacks a sealing mechanism for sample containers, and sample storage relies solely on the basic space separation of the item placement cavity. This makes it prone to cross-contamination due to tool contact. Furthermore, the functions of its quarantine platform components, such as deployment, tool retrieval, and waste disposal, are independent and lack linkage design. During sampling, operations such as "deploying the platform - retrieving tools - disposing of waste" must be completed step by step, reducing on-site operational efficiency.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing rapid detection and sampling toolkit for yak brucellosis. Summary of the Invention

[0006] The purpose of this invention is to provide a rapid sampling toolbox for brucellosis detection in yaks, in order to solve the problems mentioned in the background art, such as the existing livestock quarantine toolbox adopting a split structure, which does not form an integrated linkage opening and closing mechanism, resulting in tools being scattered and cumbersome to use, and lacking disinfection devices and sample container sealing mechanisms, and there is no linkage between functions, which can easily cause cross-contamination and reduce the efficiency and practicality of on-site operations.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rapid detection sampling toolbox for yak brucellosis, comprising a placement plate, a storage box one, a storage box two, and a fixed base. A slider is fixedly installed on the rear side of the placement plate, the storage box one, and the storage box two. A limiting rail is sleeved on the outer side of the slider, and the bottom of the limiting rail is fixedly connected to the fixed base. A limit opening and closing mechanism is connected between the placement plate, storage box one, storage box two, and the fixed base; The storage box one and storage box two are equipped with a movable sealing mechanism inside, and the movable sealing mechanism is linked with the limiting opening and closing mechanism; Piston power mechanisms are symmetrically installed on the rear side of the fixed base; The limiting track is internally threaded with a positioning pin, and a liquid storage tank is fitted into the bottom of the fixed base. A liquid replenishment seat is installed on the front side of the liquid storage tank. A waste storage box is slidably installed inside the fixed base, and a telescopic disinfection mechanism is movably installed on the top of the fixed base.

[0008] Preferably, the limiting opening and closing mechanism includes limiting slide grooves symmetrically opened on the rear sides of storage box one, storage box two and fixed base. A positioning rod is fixedly installed inside the limiting slide groove. A slide seat is slidably sleeved on the outer ring of the positioning rod. The slide seat is slidably connected to the limiting slide groove. A telescopic spring is sleeved on the outer ring of the positioning rod inside the slide seat. The two ends of the telescopic spring are fixedly connected to the inner walls of the slide seat and the limiting slide groove, respectively. The slide seat and the limiting slide groove form a telescopic structure through the telescopic spring.

[0009] Preferably, the limiting opening and closing mechanism further includes positioning posts symmetrically installed on the rear sides of the placement plate, storage box one, and storage box two. Support plates are rotatably connected between the positioning posts on the rear side of the placement plate and the slide on the rear side of storage box one, between the positioning posts on the rear side of storage box one and the slide on the rear side of storage box two, and between the positioning posts on the rear side of storage box two and the slide on the rear side of the fixed base.

[0010] By adopting the above technical solution, through the combination structure of "limiting slide groove - positioning rod - sliding block - telescopic spring", and with the rotational connection between the positioning column and the support plate, the integrated linkage opening and closing of the placement plate, storage box one, storage box two and fixed base is realized. Before sampling, it is only necessary to release the restriction of the positioning pin, and the support plate can be rotated by the push of the telescopic spring, which will drive the components to unfold in an orderly manner. There is no need to take tools separately, which completely solves the pain point of existing tools being "dispersed and easy to miss". Furthermore, the placement plate can be squeezed after sampling to reset the slide and retract each component, reducing the overall size of the toolbox and improving portability. At the same time, the support plate unfolds to form a stable support structure, preventing the toolbox from shaking during sampling and ensuring stability.

[0011] Preferably, the movable sealing mechanism includes a positioning seat that is fitted and installed inside storage box one and storage box two. The positioning seat has a lifting groove inside, and a movable sealing element is slidably installed inside the lifting groove. Both the placement plate and the bottom of storage box one have sealing grooves.

[0012] Preferably, the movable sealing mechanism further includes a piston box 1 fixedly installed on both sides of storage box 1 and storage box 2. A connecting pipe is connected between the piston box 1 and the bottom of the lifting slide groove. A piston plate 1 is slidably installed inside the piston box 1. Return springs are symmetrically installed between the piston plate 1 and the outer inner wall of the piston box 1. A venting groove is opened on the inner side of the rear end of the piston box 1. A linkage rod is fixedly installed on the inner side of the piston plate 1. When the support plate expands outward, it squeezes the linkage rod to realize the rise of the movable sealing element.

[0013] By adopting the above technical solution, through the sealing base structure of "positioning seat - movable seal" and the linkage design of "piston box - connecting pipe - linkage rod" and the limit opening and closing mechanism, automatic sealing protection of sample storage is realized. When the support plate expands outward to open the toolbox, it will simultaneously squeeze the linkage rod to push the piston plate one. Through the connecting pipe, the gas in the piston box one is forced into the lifting slide groove, which drives the movable seal to rise and tightly fit the sealing groove opened at the bottom of the placement plate and storage box one, solving the pain point of "poor sealing and easy cross-contamination" of existing samples and ensuring sample quality. The reset spring can pull the piston plate to reset when the support plate retracts, causing the movable seal to descend, which facilitates the placement and removal of sample containers. The vent groove can balance the internal air pressure of the piston box, ensuring smooth lifting and lowering of the movable seal.

[0014] Preferably, the piston power mechanism includes a piston box two symmetrically installed on the rear side of the fixed base. A piston plate two is slidably installed inside the piston box two. A connecting rod is fixedly installed on the top surface of the piston plate two. A connecting seat is fixedly installed at the top end of the connecting rod. The connecting seat is fixedly connected to the slider on the rear side of the storage box two.

[0015] Preferably, the piston power mechanism further includes a one-way three-way valve connected to the inner side of the bottom of the piston box two. The inlet end of the one-way three-way valve is fixedly connected to the liquid storage tank. A one-way outlet valve is embedded on the outer side of the bottom of the piston box two. A connecting pipe is fixedly connected to the outlet end of the one-way outlet valve. The connecting pipe is fixedly connected to the fixed base through a mounting seat. A telescopic bellows is fixedly connected to the outlet end of the connecting pipe. A diverter pipe is fixedly installed at the outlet end of the telescopic bellows. An atomizing nozzle is fixedly installed at the outlet end of the diverter pipe.

[0016] By adopting the above technical solution, through the linkage design of "piston box two - piston plate two - connecting rod" and storage box two, and in conjunction with the fluid control structure of "one-way three-way valve - atomizing nozzle", automatic atomizing disinfection without external power is realized. When storage box 2 unfolds, the connecting rod pulls piston plate 2 upward, creating negative pressure inside piston box 2. Disinfectant is drawn from the storage tank through a one-way three-way valve. When storage box 2 retracts, piston plate 2 descends and squeezes the disinfectant, which is then transported to the distribution pipe through a one-way outlet valve, connecting pipe, and telescopic corrugated pipe. Finally, the disinfectant is sprayed out through the atomizing nozzle to disinfect the waste sampled inside the waste storage box. This design facilitates the linkage of the toolbox opening and closing action. The design of the storage tank and replenishment base allows for easy replenishment of disinfectant at any time, meeting the disinfection needs of multiple sampling sessions and improving the continuity of on-site operations.

[0017] Preferably, a fixing block is symmetrically installed on the rear side of the fixing base, and a protective plate is fixedly installed on the fixing block.

[0018] By adopting the above technical solution, the protective plate is stably installed on the rear side of the fixed base by the fixing block, which can form a physical protective barrier for the limit opening and closing mechanism and piston power mechanism on the rear side of the toolbox, preventing personnel from accidentally touching the linkage components on the rear side during the sampling process and ensuring operational safety.

[0019] Preferably, the telescopic disinfection mechanism includes a symmetrically sliding opening and closing plate on the top of the fixed base. The opening and closing of the top of the opening and closing plate realizes the opening and closing of the top of the fixed base. The outer end of the opening and closing plate provides stable support for the whole when it is open. The diverter pipe and the atomizing nozzle are fitted and installed inside the top of the opening and closing plate. The telescopic disinfection mechanism also includes a roller rotatably mounted on the inner rear side of the opening and closing plate. A drive plate is fixedly mounted on the bottom rear side of the storage box two. A connecting groove is provided inside the drive plate. The connecting groove is slidably connected to the roller. The connecting groove is obliquely opened.

[0020] By adopting the above technical solution, through the linkage structure of "opening and closing plate - drive plate - roller", and combining the dual functions of the opening and closing plate as a support and a disinfection carrier, the disinfection range is expanded and the operational stability is improved. When the storage box 2 is unfolded, the drive plate at its bottom pushes the rollers through the inclined connecting groove, causing the opening and closing plate to slide open to both sides. At this time, the diversion tube and atomizing nozzle embedded at the top of the opening and closing plate expand outwards. The unfolded opening and closing plate can form a stable support structure with the fixed base, improving the stability of the toolbox on the uneven ground of the high-altitude pasture and preventing the toolbox from tipping over during sampling. When stored, the opening and closing plate can retract to the top of the fixed base, and during the movement, the disinfectant sprayed by the atomizing nozzle will cover and disinfect the test and sampled waste inside the waste storage box, without increasing the volume of the toolbox, thus balancing portability and disinfection function.

[0021] Preferably, a sealing strip for sealing is fixedly installed on the outer end of the top surface of the opening and closing plate, and replaceable absorbent sponges are installed on the inner side of the outer end of the opening and closing plate and on both sides of the fixed base. Using the above technical solution, after the opening and closing plate is closed, the sealing strip and the absorbent sponge can effectively seal the gap between the opening and closing plate and the fixed base, thereby preventing disinfectant or pollutants from leaking out of the gap. At the same time, the absorbent sponge can absorb the disinfectant and pollutants that leak out of the gap, and the absorbent sponge can be easily replaced.

[0022] Compared with existing technologies, the beneficial effects of this invention are as follows: This rapid yak brucellosis detection sampling toolbox integrates multiple linkage mechanisms such as limit opening and closing, movable sealing, piston power, and telescopic disinfection, achieving coordinated functions of tool retrieval, sample protection, disinfection, and stable operation. It effectively solves the pain points of existing livestock quarantine toolboxes, such as scattered tools, easy sample contamination, incomplete disinfection, and poor stability, significantly improving the efficiency, safety, and portability of field sampling. It is suitable for the complex operational scenarios of high-altitude pastures. Specific details are as follows: The limiting opening and closing mechanism, through its combined design, achieves integrated linkage opening and closing of the placement plate, storage box one, storage box two, and fixed base. After releasing the positioning pin, the telescopic spring can push the support plate to rotate, causing each component to unfold in an orderly manner, avoiding the problem of omission caused by tools being scattered and taken out. When retracted, the slide can be reset by squeezing the placement plate, which greatly reduces the overall volume and improves portability. At the same time, the support plate forms a stable support structure after unfolding, effectively preventing shaking and providing a stable operating foundation. The movable sealing mechanism is linked with the limit opening and closing mechanism to achieve automatic sealing protection for sample storage. When the support plate expands outward, it squeezes the linkage rod, pushes the piston plate to push the gas into the lifting slide through the connecting pipe, drives the movable sealing part to rise and tightly fit the sealing groove to form a sealed space, which solves the problem of cross-contamination of samples caused by insufficient sealing. When the support plate retracts, the return spring pulls the piston plate to return to its original position, driving the movable sealing part to descend, which facilitates the loading and unloading of sample containers. The piston power mechanism, relying on the linkage with the storage box two, realizes automatic atomization disinfection without external power. When the storage box two is opened, the piston plate two is pulled up by the connecting rod, so that the piston box two forms a negative pressure and draws disinfectant from the storage tank. When it is contracted, the piston plate two descends and squeezes the disinfectant, which is then sprayed out from the atomizing nozzle through the one-way outlet valve and the diversion pipe, thus completing the disinfection of pollutants in the waste storage box. The opening and closing action realizes the disinfection linkage, improving the convenience and functionality of use. The telescopic disinfection mechanism achieves comprehensive disinfection and improved operational stability. When the storage box is unfolded, the inclined connecting groove of the drive plate pushes the rollers, causing the opening and closing plate to slide to both sides. This allows the opening and closing plate to form a stable support structure with the fixed base after unfolding, enhancing stability on uneven ground. When retracted, the opening and closing plate is stored on top of the fixed base, achieving comprehensive disinfection of the waste storage box without adding extra volume, thus balancing disinfection function and portability.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-11This invention provides a technical solution: a rapid sampling toolbox for yak brucellosis detection, comprising a placement plate 1, a first storage box 2, a second storage box 3, and a fixed base 4. A slider 5 is fixedly installed on the rear side of the placement plate 1, the first storage box 2, and the second storage box 3. A limiting rail 6 is sleeved on the outer side of the slider 5, and the bottom of the limiting rail 6 is fixedly connected to the fixed base 4. A limiting opening and closing mechanism is connected between the placement plate 1, the first storage box 2, the second storage box 3, and the fixed base 4. The limiting opening and closing mechanism includes limiting grooves 7 symmetrically opened on the rear side of the first storage box 2, the second storage box 3, and the fixed base 4. A positioning rod 8 is fixedly installed inside the limiting groove 7. A sliding seat 9 is slidably sleeved on the outer ring of the positioning rod 8. The sliding seat 9 is slidably connected to the limiting groove 7. The positioning rod 8 is positioned inside the sliding seat 9. A telescopic spring 10 is fitted around the outer ring of the rod 8. The two ends of the telescopic spring 10 are fixedly connected to the inner walls of the slide block 9 and the limiting slide groove 7, respectively. The slide block 9 forms a telescopic structure with the limiting slide groove 7 through the telescopic spring 10. The limiting opening and closing mechanism also includes positioning pins 12 symmetrically installed on the rear side of the placement plate 1, storage box 1 2 and storage box 2 3. Support plates 11 are rotatably connected between the positioning pin 12 on the rear side of the placement plate 1 and the slide block 9 on the rear side of storage box 1 2, between the positioning pin 12 on the rear side of storage box 1 2 and the slide block 9 on the rear side of storage box 2 3, and between the positioning pin 12 on the rear side of storage box 2 3 and the slide block 9 on the rear side of the fixed base 4. The internal thread of the limiting track 6 is connected to a positioning pin 32. Fixed blocks 33 are symmetrically installed on the rear side of the fixed base 4. Protective plates 34 are fixedly installed on the fixed blocks 33. In the initial storage state of the above structure, the positioning pin 32 in the limiting track 6 is in a locked state, fixing the placement plate 1, storage box 1 2, and storage box 2 3 in the retracted position. At this time, the telescopic spring 10 in the limiting slide groove 7 is in a stretched energy storage state due to the stretching of the slide block 9, and the support plate 11 is attached to the rear side of each component to maintain a compact storage form.

[0027] When the toolbox needs to be unfolded, first remove the positioning pin 32 on the limiting rail 6 to release the locking restrictions on each component. At this time, the compressed telescopic spring 10 releases its elastic potential energy and pushes the slide 9 to slide inward along the positioning rod 8 in the limiting slide groove 7. Since the two ends of the support plate 11 are rotatably connected to the positioning post 12 and the slide 9 of the adjacent components, the sliding of the slide 9 will drive the support plate 11 to rotate inward around the connection point of the positioning post 12 and the slide 9. During this process, the slider 5 on the back of the placement plate 1, storage box 1 2, and storage box 2 3 will slide upward synchronously along the limiting rail 6 to ensure that each component unfolds stably in the vertical direction and avoids lateral displacement. As the support plate 11 continues to rotate to a near-vertical state, the distance between the connection points at both ends reaches the minimum. At this time, the placement plate 1, storage box 1 2, and storage box 2 3 are fully unfolded, and the support plate 11 forms a support structure to stably support each component at different heights, providing a flat and stable platform for tool retrieval and sample operation. When the sampling is completed and needs to be stored, press the placement plate 1 towards the fixed base 4. The placement plate 1 slides down along the limiting track 6 via the slider 5, and then pushes the support plate 11 to rotate via the positioning post 12. The rotation of the support plate 11 will drive the slide 9 to slide along the positioning rod 8 to the outside of the limiting slide groove 7, while stretching the telescopic spring 10 to store energy. When the placement plate 1, storage box 1 2, and storage box 2 3 are completely retracted to the initial position, install the positioning pin 32 on the limiting track 6 to lock and fix the slider 5, completing the storage. At this time, the overall volume of the toolbox is greatly reduced, making it easy to carry and transport.

[0028] The storage boxes 1 and 2 are equipped with a movable sealing mechanism. The movable sealing mechanism is linked with the limiting opening and closing mechanism. The movable sealing mechanism includes a positioning seat 13 that is fitted inside the storage boxes 1 and 2. The positioning seat 13 has a lifting slide 14 inside. The movable sealing element 15 is slidably installed inside the lifting slide 14. The bottom of the placement plate 1 and the storage box 1 are both provided with sealing grooves. The movable sealing mechanism also includes a piston box 16 fixedly installed on both sides of the storage boxes 1 and 2. A connecting pipe 17 is connected between the piston box 16 and the bottom of the lifting slide 14. A piston plate 18 is slidably installed inside the piston box 16. A return spring 19 is symmetrically installed between the piston plate 18 and the outer inner wall of the piston box 16. A vent groove 20 is provided on the inner side of the rear end of the piston box 16. A linkage rod 21 is fixedly installed on the inner side of the piston plate 18. When the support plate 11 expands outward, it squeezes the linkage rod 21 to realize the rise of the movable sealing element 15. In the above-described structure, when the support plate 11 of the limiting opening and closing mechanism expands outward, its rotation trajectory will contact the outer end of the linkage rod 21 and generate compression. The outward expansion force of the support plate 11 pushes the linkage rod 21 to move inward toward the piston box 16, thereby causing the piston plate 18, which is fixedly connected to the linkage rod 21, to slide outward along the inner wall of the piston box 16. At this time, the return spring 19 on the outer side of the piston box 16 is compressed and stored by the piston plate 18, the internal space of the piston box 16 is compressed, and the gas in the cavity is forced into the lifting slide groove 1 of the positioning seat 13 through the connecting pipe 17. 4. As the gas pressure inside the lifting slide 14 gradually increases, the gas pressure will generate an upward thrust on the bottom of the movable seal 15, pushing the movable seal 15 to rise vertically along the lifting slide 14. When the support plate 11 is fully extended and the toolbox reaches the retracted and closed state, the movable seal 15 just rises to the top, and its top end fits tightly against the sealing groove at the bottom of the placement plate 1 and the bottom of the storage box 1 2, forming a sealed space inside the storage box 1 2 and the storage box 2 3, sealing the storage box 1 2 and the storage box 2 3, effectively isolating external pollution and preventing cross contact with other tools. After sampling, when the support plate 11 of the limiting opening and closing mechanism retracts in the reverse direction, the squeezing force of the support plate 11 on the linkage rod 21 disappears. At this time, the return spring 19 compressed on the outside of the piston box 16 releases its elastic potential energy, pushing the piston plate 18 to slide inward. The internal space of the piston box 16 expands again, forming a negative pressure. The gas in the lifting slide 14 flows back to the piston box 16 through the connecting pipe 17. The movable seal 15, due to the loss of air pressure support, naturally descends to the bottom along the lifting slide 14. The staff can directly and conveniently remove the testing and sampling tools in the storage box 2 and storage box 3.

[0029] A piston power mechanism is symmetrically mounted on the rear side of the fixed base 4. The piston power mechanism includes a piston box 22 symmetrically mounted on the rear side of the fixed base 4. A piston plate 23 is slidably mounted inside the piston box 22. A connecting rod 24 is fixedly mounted on the top surface of the piston plate 23. A connecting seat 25 is fixedly mounted on the top end of the connecting rod 24. The connecting seat 25 is fixedly connected to the slider 5 on the rear side of the storage box 3. The piston power mechanism also includes a one-way three-way valve 26 connected to the inner bottom of the piston box 22. The inlet end of the one-way three-way valve 26 is connected to the storage box. The piston box 22 is fixedly connected to the bottom outer side of the piston box 22. A one-way liquid outlet valve 27 is embedded in the bottom outer side of the piston box 22. A connecting pipe 28 is fixedly connected to the liquid outlet end of the one-way liquid outlet valve 27. The connecting pipe 28 is fixedly connected to the fixed base 4 through the mounting seat. A telescopic bellows 29 is fixedly connected to the liquid outlet end of the telescopic bellows 29. A diverter pipe 30 is fixedly installed at the liquid outlet end of the diverter pipe 30. An atomizing nozzle 31 is fixedly installed at the liquid outlet end of the diverter pipe 30. A liquid storage tank 35 is fitted into the bottom of the fixed base 4. A replenishment seat 36 is installed on the front side of the liquid storage tank 35. In the above-described structure, when the limiting opening and closing mechanism drives the storage box 2 3 to unfold upwards, the slider 5 on the rear side of the storage box 2 3 drives the connecting rod 24 to be lifted upwards synchronously through the connecting seat 25. The connecting rod 24 pulls the piston plate 23 inside the piston box 22 to slide upwards along the box wall, causing the internal space of the piston box 22 to expand rapidly and a negative pressure to be formed inside the cavity. Under the action of the negative pressure, the liquid inlet channel of the one-way three-way valve 26 is opened, and the disinfectant pre-filled in the storage tank 35 is sucked into the piston box 22 through the one-way three-way valve 26. When the storage box 2 3 is fully unfolded, the piston plate 23 rises to the top of the piston box 22, and the piston box 22 is filled with disinfectant, and the liquid suction process ends. After sampling, when the limiting opening and closing mechanism drives the storage box 2 3 to retract downward, the slider 5 on the rear side of the storage box 2 3 drives the connecting rod 24 to press downward synchronously through the connecting seat 25. The connecting rod 24 pushes the piston plate 23 in the piston box 2 22 to slide downward along the box wall, squeezing the disinfectant in the piston box 2 22, causing the pressure in the cavity to rise rapidly. At this time, under the action of high pressure, the outlet channel of the one-way outlet valve 27 is opened, and the disinfectant in the piston box 2 22 enters the connecting pipe 28 through the one-way outlet valve 27 under pressure. Then, the disinfectant entering the connecting pipe 28 is transported to the telescopic corrugated pipe 29 along the pipeline, and then diverted to multiple atomizing nozzles 31 through the diversion pipe 30, and finally sprayed out in the form of atomization to disinfect the waste storage box 37 in the fixed base 4.

[0030] A waste storage box 37 is slidably installed inside the fixed base 4. A telescopic disinfection mechanism is movably installed on the top of the fixed base 4. The telescopic disinfection mechanism includes an opening and closing plate 38 symmetrically slidably arranged on the top of the fixed base 4. The opening and closing of the top of the opening and closing plate 38 realizes the opening and closing of the top of the fixed base 4. The outer end of the opening and closing plate 38 provides stable support for the whole when it is open. The diverter pipe 30 and the atomizing nozzle 31 are fitted and installed inside the top of the opening and closing plate 38. The telescopic disinfection mechanism also includes a roller 39 rotatably installed on the inner rear side of the opening and closing plate 38. A drive plate 40 is fixedly installed on the bottom rear side of the storage box 3. A connecting groove 41 is opened inside the drive plate 40. The connecting groove 41 is slidably connected to the roller 39. The connecting groove 41 is opened at an angle. In the above-described structure, when the limiting opening and closing mechanism drives the storage box 3 to unfold upwards, the storage box 3 simultaneously drives the bottom drive plate 40 to rise vertically. Since the connecting groove 41 of the drive plate 40 is designed at an angle and is slidably connected to the roller 39 of the opening and closing plate 38, the vertical upward force of the drive plate 40 will be converted into a horizontal outward pushing force on the roller 39 through the inclined inner wall of the connecting groove 41. Under the action of this pushing force, the opening and closing plate 38 unfolds smoothly to both sides along the sliding track at the top of the fixed base 4. When the storage box 3 is fully unfolded, the outer end of the opening and closing plate 38 just touches the ground, forming a stable support structure with the bottom of the fixed base 4, improving the stability of the toolbox and preventing the toolbox from tipping over during sampling operations. At the same time, after the opening and closing plate 38 is unfolded, the opening of the waste storage box 37 at the top of the fixed base 4 is fully exposed, and the staff can directly put the infectious waste generated during the sampling process, such as sampling needles, contaminated swabs, and waste sample tubes, into the waste storage box 37 from the opening. After sampling, when the limiting opening and closing mechanism drives the storage box 2 3 to retract downwards, the storage box 2 3 drives the drive plate 40 to descend vertically. At this time, the connecting groove 41 of the drive plate 40 exerts a horizontal inward pulling force on the roller 39, pulling the opening and closing plate 38 to retract inwards along the top of the fixed base 4. At the same time, the piston power mechanism simultaneously enters the "spraying stage". The disinfectant in the piston box 2 22 is transported to the diversion pipe 30 through the connecting pipe 28 and the telescopic corrugated pipe 29. As the opening and closing plate 38 is in the process of retraction, the atomizing nozzle 31 embedded on it will gradually "retract" with the opening and closing plate 38. The system sweeps through the interior space of the waste storage box 37, evenly spraying the atomized disinfectant onto the surface of the waste, achieving a "disinfection upon retraction" linkage effect. When the storage box 37 is fully retracted to its initial position, the opening and closing plate 38 also retracts to the top of the fixed base 4, closing again and covering the opening of the waste storage box 37. When processing the waste, the staff can pull the waste storage box 37 outward along the sliding track of the fixed base 4. After the disinfected waste is centrally processed, the waste storage box 37 is pushed back into the fixed base 4 to complete the entire storage process.

[0031] Example 2: Based on Example 1, the present invention adopts the following... Figure 12 The technical solution shown further discloses that a sealing strip 42 for sealing is fixedly installed on the outer end of the top surface of the opening and closing plate 38, and replaceable absorbent sponges 43 are installed on the inner side of the outer end of the opening and closing plate 38 and on both sides of the fixed base 4. The above structure is designed such that when the opening and closing plate 38 is closed, the sealing strip 42 at the outer end of its top surface can seal the upper gap between the opening and closing plate 38 and the fixed base 4, effectively preventing disinfectant and pollutants from leaking out of the gap. After closing, the absorbent sponge 43 on the inner side of the outer end of the opening and closing plate 38 can seal the lower gap between the opening and closing plate 38 and the fixed base 4, further preventing disinfectant and pollutants from leaking out of the gap. When the hinged panel 38 is in the unfolded state, the absorbent sponges 43 on the inner side of the outer end of the hinged panel 38 and on both sides of the fixed base 4 can absorb the disinfectant and pollutants that leak out from the gaps, thereby effectively preventing the spread of disinfectant and pollutants, and can be easily replaced when they fail.
