Description

Technical Field

[0001] This utility model relates to the field of airborne microparticle sampling and measurement technology, and in particular to an aerosol moisture-proof sampling box suitable for high humidity environments. Background Technology

[0002] A moisture-proof aerosol sampling box is a device used to collect aerosol samples. It usually has a moisture-proof function to protect the collected aerosol samples from moisture and deterioration, so that they can be used for subsequent scientific analysis.

[0003] Aerosol moisture-proof sampling boxes suitable for high humidity environments are devices specifically designed for collecting and preserving aerosol samples under high humidity conditions. They use highly efficient moisture-proof materials or technologies, such as sealing structures and desiccants, to prevent external moisture from entering the sampling box. At the same time, they employ special sample collection and fixation methods to ensure that aerosol samples remain stable in high humidity environments, so as to facilitate accurate collection and subsequent analysis.

[0004] In existing technologies, some aerosol moisture-proof sampling boxes have traditionally fixed integrated clamping mechanisms. In actual use, due to the long-term exposure of the filter box to complex environments, the internal components are easily contaminated, worn, or damaged by moisture. Once the clamping mechanism malfunctions, such as failing to tightly fix the filter paper and other filter elements, the sampling effect is greatly reduced, and the collected aerosol samples are inaccurate and incomplete, seriously affecting the subsequent detection and analysis results. Therefore, a moisture-proof aerosol sampling box suitable for high humidity environments is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an aerosol moisture-proof sampling box suitable for high humidity environments, aiming to improve the problem of significantly reduced sampling effect in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A moisture-proof aerosol sampling box suitable for high humidity environments includes a box body. A connecting tube is fixedly connected to the top inner wall of the box body. A fixing groove is formed inside the connecting tube. Multiple springs are fixedly connected to the top inner wall of the fixing groove. A connecting ring is fixedly connected to the bottom of the multiple springs. Multiple limiting posts are fixedly connected to the bottom of the connecting ring. A lever is fixedly connected to the front side of the connecting ring. A filter box is provided inside the box body. Multiple limiting holes are formed inside the filter box. A fixing groove is formed inside the filter box. Multiple springs are fixedly connected to the top inner wall of the fixing groove. Limiting rings are fixedly connected to the bottom of the multiple springs. Two portable components are fixedly connected to the right inner wall of the box body to facilitate keeping the inside of the sampling box dry.

[0008] As a further description of the above technical solution:

[0009] The portable component includes a fixing block, the fixing block has a driven groove inside, two driven grooves are respectively fixedly connected to the adjacent side of each of the two driven grooves, and two driven blocks are respectively fixedly connected to the adjacent side of each of the two driven grooves. The box body is provided with a drying box, and the upper and lower sides of the drying box are respectively fixedly connected to connecting blocks.

[0010] As a further description of the above technical solution:

[0011] The outer part of the connecting ring is slidably connected to the inside of the fixing groove, and the outer part of the limiting post is in contact with the inner wall of the limiting hole.

[0012] As a further description of the above technical solution:

[0013] The outer side of the limiting ring is slidably connected to the inside of the second fixing groove, and an exhaust pipe is fixedly connected to the bottom inner wall of the box body. The outer side of the limiting ring is in contact with the inner wall of the exhaust pipe.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the filter box is fixedly connected with multiple springs four, and the bottom of the multiple springs four is fixedly connected with a pressure ring. The inner wall of the filter box is fixedly connected with a fixing ring, and filter paper is detachably connected inside the filter box.

[0016] As a further description of the above technical solution:

[0017] The top of the box is provided with an air inlet, and the bottom of the box is provided with an exhaust outlet;

[0018] As a further description of the above technical solution:

[0019] The front side of the box is rotatably connected to a rotating door, and the far sides of the two connecting blocks and the near sides of the two driven blocks are in contact.

[0020] As a further description of the above technical solution:

[0021] The driven block is externally slidably connected to the inside of the driven groove, and the two fixed blocks are fixedly connected to the right inner wall of the box body on their right sides.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by manually moving the lever upward, the lever drives the connecting ring to rise, which in turn compresses the first spring. As the connecting ring rises, the limiting post disengages from the limiting hole, releasing the limiting effect on the filter box. The lever then drives the connecting ring and the limiting post to rise, allowing the filter box to be aligned and placed on top of the exhaust pipe. The limiting ring then engages with the exhaust pipe through the elastic action of the second spring, and the limiting post naturally falls into the limiting hole under the elastic action of the first spring, securing the filter box. This allows for quick separation or docking of the limiting post and the limiting hole by simply moving the lever, greatly improving the efficiency of maintenance and component replacement. The filter box is stable and reliable after installation, ensuring that the aerosol collection effect is not affected by shaking or other factors during sampling.

[0024] 2. In this utility model, the connecting block on the moving drying box first squeezes the driven block on one side, and then the driven block on one side squeezes the spring three. Then, the connecting block on the other side is aligned with the driven groove on the other side. Then, through the elastic action of the spring three, the driven block on one side pushes the connecting block on one side, and then drives the connecting block on the other side to squeeze the driven block on the other side. Through the elastic support of the driven blocks by the spring three on both sides, the connecting block is stuck inside the driven groove. The drying box is first pushed to one side, and then the connecting block squeezes the driven block, causing the connecting block on the other side to disengage from the driven groove. This effectively ensures the stability of the drying environment inside the box, provides good conditions for aerosol sampling, facilitates quick removal of the drying box to replenish the desiccant, and greatly improves the convenience and efficiency of daily maintenance of the sampling box.

[0033] 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.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of an aerosol moisture-proof sampling box suitable for high humidity environments, comprising a box body 1, which provides installation space and protection for internal components. A connecting pipe 2 is fixedly connected to the top inner wall of the box body 1. The connecting pipe 2 receives and transports gas collected from the air inlet 23. A fixing groove 3 is provided inside the connecting pipe 2. The fixing groove 3 provides fixing and support for the spring 4, and also provides limiting and guiding functions for the connecting ring 5. Multiple springs 4 are fixedly connected to the top inner wall of the fixing groove 3. The springs 4 have an elastic function and provide elastic support for the connecting ring 5.

[0035] Multiple springs 4 are fixedly connected to a connecting ring 5 at their bottom. The connecting ring 5 provides fixation and support for the limiting post 6. Multiple limiting posts 6 are fixedly connected to the bottom of the connecting ring 5. The limiting posts 6 are used to cooperate with the limiting hole 18 to complete the limiting fixation of the filter box 8. A lever 7 is fixedly connected to the front side of the connecting ring 5. When the internal components of the filter box 8 need to be maintained or replaced after long-term use, the operator moves the lever 7 upward, thereby driving the connecting ring 5 to squeeze the spring 4, thereby driving the limiting post 6 to disengage from the inside of the limiting hole 18, thereby releasing the limiting of the filter box 8.

[0036] Reference Figure 2 and Figure 6The housing 1 contains a filter box 8. The filter box 8 provides installation space and protection for the sampling element. The filter box 8 has multiple limiting holes 18. The limiting post 6 and the limiting holes 18 work together to limit and fix the filter box 8. The filter box 8 has a fixing groove 9. The fixing groove 9 provides fixation and support for the spring 10, and also provides limiting and guiding for the limiting ring 11. Multiple springs 10 are fixedly connected to the top inner wall of the fixing groove 9. The springs 10 are elastic. When the filter box 8 is installed, if the limiting post 6 is inserted into the limiting hole 18, the limiting ring 11 at the bottom of the filter box 8 will be reset by the elasticity of the springs 10 and inserted into the exhaust pipe 25, thus fixing the filter box 8. The bottom of the multiple springs 10 is fixedly connected to the limiting ring 11. The limiting ring 11 is used to insert into the exhaust pipe 25, thus fixing the filter box 8. Two portable components are fixedly connected to the right inner wall of the housing 1 to facilitate keeping the inside of the sampling box dry.

[0037] Reference Figure 2 and Figure 3 The portable component includes a fixing block 12, which provides space for the driven slot 13. The driven slot 13 is provided inside the fixing block 12. The driven slot 13 provides a fixing and support function for the spring 14, and thus provides a limiting and guiding function for the driven block 15. The spring 14 is fixedly connected to the adjacent side of the two driven slots 13 respectively. The spring 14 has an elastic function and provides elastic support for its driven block 15.

[0038] Two springs 14 are respectively fixedly connected to adjacent sides of driven blocks 15. Driven blocks 15 receive elastic support from springs 14 and transmit force to connecting blocks 16, so that connecting blocks 16 are just inserted into the interior of driven grooves 13. By pressing the connecting blocks 16 with the driven blocks 15 on both sides, they are just inserted into the interior of driven grooves 13, thus completing the fixation of the drying box 17. When desiccant needs to be added, the drying box 17 is moved, so that the connecting block 16 on one side presses against the driven block 15, so that the connecting block 16 on the other side is disengaged from the interior of driven grooves 13, and the drying box 17 can be removed. The drying box 17 is provided inside the box body 1. The drying box 17 provides space for the desiccant and keeps the inside of the sampling box dry. Connecting blocks 16 are fixedly connected to the upper and lower sides of the drying box 17, and the connecting blocks 16 are used to insert into the interior of driven grooves 13 to fix the drying box 17.

[0039] Reference Figures 2 to 4The outer side of the connecting ring 5 is slidably connected to the inside of the fixing groove 1 3. The fixing groove 1 3 provides a limit and guide for the connecting ring 5. The outer side of the limiting post 6 is in contact with the inner wall of the limiting hole 18. The outer side of the limiting ring 11 is slidably connected to the inside of the fixing groove 2 9. The fixing groove 2 9 provides a limit and guide for the limiting ring 11. The bottom inner wall of the box body 1 is fixedly connected to the exhaust pipe 25. After the filter paper 22 collects the aerosol, the excess gas is discharged through the exhaust pipe 25. The outer side of the limiting ring 11 is in contact with the inner wall of the exhaust pipe 25. Similarly, when the filter box 8 is installed, when the limiting post 6 is inserted into the limiting hole 18, the limiting ring 11 at the bottom of the filter box 8 is elastically reset by the spring 2 10 and inserted into the exhaust pipe 25, thereby completing the fixation of the filter box 8.

[0040] Multiple springs 19 are fixedly connected to the inner wall of the filter box 8. The springs 19 have an elastic function and provide elastic support for the pressure ring 20. The pressure ring 20 is fixedly connected to the bottom of the multiple springs 19. The pressure ring 20 can be moved by the front moving block. When the filter paper 22 needs to be replaced, the filter paper 22 can be taken out and replaced by moving the pressure ring 20 upward. The inner wall of the filter box 8 is fixedly connected to the fixing ring 21. The fixing ring 21 cooperates with the pressure ring 20 to fix the filter paper 22. The filter paper 22 is detachably connected inside the filter box 8. The filter paper 22 is used for air passage and sample collection. The top of the box body 1 is provided with an air inlet 23. The air inlet 23 collects the required gas into the collection box. The bottom of the box body 1 is provided with an exhaust port 24. The exhaust port 24 is used to remove excess gas.

[0041] A rotating door 26 is rotatably connected to the front of the box body 1. The rotating door 26 allows the operator to easily view the internal components or add desiccant. The far sides of the two connecting blocks 16 and the near sides of the two driven blocks 15 are in contact. The two connecting blocks 16 are squeezed by the two driven blocks 15, which allows the connecting blocks 16 on both sides to be inserted into the interior of the driven groove 13, thus completing the limiting and fixing of the drying box 17. The outside of the driven blocks 15 is slidably connected to the interior of the driven groove 13. The driven groove 13 provides limiting and fixing for the driven blocks 15. The right side of the two fixing blocks 12 is fixedly connected to the right inner wall of the box body 1. The box body 1 provides fixing and support for the fixing blocks 12.

[0042] Working principle: During use, before sampling begins, aerosol-containing gas enters through inlet 23 and is guided by connecting pipe 2. When it is necessary to disassemble filter box 8 for maintenance or replacement of internal components, the operator manually moves the lever 7 upwards. Lever 7 then moves the connecting ring 5 upwards, which in turn compresses spring 4. As the connecting ring 5 rises, the limiting post 6 disengages from the limiting hole 18, releasing the limiting of filter box 8. Filter box 8 can then be easily removed from the box body 1. During installation, lever 7 moves the connecting ring 5 and limiting post 6 upwards, aligning filter box 8 and placing it on top of exhaust pipe 25. Limiting ring 11 is then engaged inside exhaust pipe 25 by the elastic action of spring 10. Limiting post 6 then naturally falls into limiting hole 18 under the elastic action of spring 4, securing filter box 8.

[0043] When it is necessary to keep the inside of the box 1 dry, after the additive is added, when installing the drying box 17, by moving the connecting block 16 on the drying box 17, one side of the driven block 15 is first squeezed, and then the driven block 15 on one side squeezes the spring 14. Then, the connecting block 16 on the other side is aligned with the driven groove 13 on the other side. Then, through the elastic action of the spring 14, the driven block 15 on one side pushes the connecting block 16 on one side, and then the connecting block 16 on the other side squeezes the driven block 15 on the other side. Through the elastic support of the driven blocks 15 by the springs 14 on both sides, the connecting block 16 is locked inside the driven groove 13, thus completing the fixation of the drying box 17. When it is necessary to add desiccant, the drying box 17 is first pushed to one side, and then the connecting block 16 squeezes the driven block 15, causing the connecting block 16 on the other side to disengage from the driven groove 13. Thus, the drying box 17 can be easily removed for desiccant replenishment, continuously ensuring the dry environment inside the sampling box.

[0044] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
