Description

Technical Field

[0001] This utility model relates to the field of air sampling technology, and in particular to an ambient air sampling device. Background Technology

[0002] Based on human needs for air quality safety, and through evolution from simple to complex and from manual to intelligent, relying on the cross-integration of multiple disciplines such as materials, analysis, and control, air sampling technology will continue to develop towards higher precision, intelligence, and multi-functionality as environmental problems become more diversified and detection needs become more refined, providing stronger technical support for atmospheric environmental management and human health protection.

[0003] Ambient air sampling devices typically consist of an air inlet, a sampling pump, a flow meter, a collection medium (such as a filter membrane or adsorption tube), and a housing. The principle is as follows: the sampling pump draws in air, which enters the device through the air inlet. The air flows through a specific collection medium (the filter membrane captures particulate matter, and the adsorption tube enriches gaseous pollutants). The flow meter controls the stable flow rate and sampling volume, thereby capturing the target pollutants for subsequent laboratory analysis.

[0004] Traditional ambient air sampling devices, by extracting air from a single location, lack flexibility and cannot sample air at different heights and angles, thus limiting their use. To address this issue, an ambient air sampling device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an ambient air sampling device, which aims to improve the problem of limited sampling angle and reduced flexibility in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ambient air sampling device, comprising a control panel, a mounting groove fixedly connected to the bottom of the control panel, a fixing slot fixedly connected to the bottom of the mounting groove, four support rods fixedly connected to the bottom of the fixing slot, support blocks fixedly connected to the bottom of the four support rods, a sleeper rail fixedly connected to the top of the support blocks, two sliding plates slidably connected to the top of the sleeper rail, a limiting block fixedly connected to the top of each of the two sliding plates, a sliding rod slidably connected inside the two limiting blocks, two springs sleeved on the outside of the sliding rods, and a height adjustment component fixedly connected to the bottom of the support blocks;

[0007] As a further description of the above technical solution: a fixed shaft is fixedly connected to the top of the control panel, a support shaft is fixedly connected to the top of the fixed shaft, an air trap is fixedly connected to the top of the support shaft, a support plate is fixedly connected to one side of the control panel, two absorption bottles are fixedly connected to the top of the support plate, a hose is fixedly connected to the top of each of the two absorption bottles, a mounting hole is fixedly connected to the end of each of the two hoses away from the absorption bottle, one side of the mounting hole is fixedly connected to the top of the control panel, a display screen is fixedly connected to one side of the control panel, and four control buttons are fixedly connected to one side of the control panel.

[0008] As a further description of the above technical solution: the control panel is externally fixedly connected to three protective railings, and a timing button is fixedly connected to one side of the control panel;

[0009] As a further description of the above technical solution: a data interface is fixedly connected to one side of the control panel, and a temperature adjustment knob is fixedly connected to one side of the control panel;

[0010] As a further description of the above technical solution: the height adjustment component includes a rotating shaft, a telescopic rod rotatably connected to the bottom of the rotating shaft, a screw threaded to the bottom of the telescopic rod, a limiting roller fixedly connected to the bottom of the telescopic rod, a fixed roller fixedly connected to the bottom of the limiting roller, and three support columns rotatably connected to the bottom of the limiting roller, with connecting plates rotatably connected to the outer sides of each of the three support columns.

[0011] As a further description of the above technical solution: the bottom of the telescopic rod is slidably connected to the inside of the fixed roller, and a sliding ring is rotatably connected to one side of the connecting plate;

[0012] As a further description of the above technical solution: the sliding ring is internally slidably connected to the outside of the fixed roller, and a motor is fixedly connected to the top of the support block;

[0013] As a further description of the above technical solution: the telescopic rod has multiple screw holes inside, and the sliding ring is slidably connected to the outside of the fixed roller.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by sliding the telescopic rod in the fixed roller and connecting the screw thread to the appropriate screw hole on the telescopic rod, the equipment can be adjusted to the required height. The various structures are interlocked and precisely matched to form an efficient transmission chain, which greatly improves the installation speed and thus achieves the effect of height adjustment.

[0016] 2. In this utility model, the connecting shaft can be rotated by the control key. When the connecting shaft rotates, it drives the support block to rotate. The rotation of the support block drives the object on the support block to rotate. All components achieve linkage and rotation through rotational cooperation. The structure is compact and ingenious, and the operation is simple and convenient, so as to solve the problem of fixed angle sampling.

[0017] 3. In this utility model, during installation, the sliding ring drives the connecting plate and support column outward away from the fixed roller. By sliding the telescopic rod and adjusting the screw to the required height, the motor is then started. Under the starting of the motor, the two sliding plates slide inward on the sleeper rail. When the two sliding plates slide inward, they drive the two limiting blocks to slide inward. When the two limiting blocks slide inward, they drive the springs to press inward. At this time, the mounting groove is aligned with the fixing slot. Then, the two limiting blocks slide outward under the elastic force of the two springs, so that the two limiting blocks lock into the mounting groove, thereby completing the installation of the equipment.

[0024] 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.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of an ambient air sampling device, including a control panel 1. The control panel 1 can be used to integrate the device's control module and display module to realize parameter setting and status monitoring of the sampling process. The bottom of the control panel 1 is fixedly connected to a mounting groove 15. The mounting groove 15 adopts a groove-type structure design, with a smooth inner wall and dimensions adapted to a fixed slot 16, providing a positioning reference for the installation of the device body. The bottom of the mounting groove 15 is fixedly connected to a fixed slot 16, which is rigidly connected to the mounting groove 15 by bolts. The four connecting holes at the bottom of the fixed slot 16 can accurately align with support rods 17 to ensure the stability of the structural connection. The bottom of the fixed slot 16 is fixedly connected to four support rods 17. The four support rods 17 are rectangularly distributed and made of high-strength metal material, which can evenly bear the weight of the upper part of the device and provide vertical support force. The bottom of the four support rods 17 is fixedly connected to a support block 18. The support block 18 is a rectangular plate structure with anti-slip texture on its bottom to increase friction with the ground and provide a mounting base for the height adjustment component.

[0026] A sleeper rail 19 is fixedly connected to the top of the support block 18. The sleeper rail 19 is a long strip track structure with a polished top surface to reduce the resistance of the sliding plate 20 during sliding, enabling smooth lateral movement. Two sliding plates 20 are slidably connected to the top of the sleeper rail 19. The two sliding plates 20 contact the sleeper rail 19 through pulleys at the bottom and can slide inward or outward along the track under the drive of the motor 24, thereby driving the limiting block 21 to perform locking or releasing actions. A limiting block 21 is fixedly connected to the top of each of the two sliding plates 20. The limiting block 21 has a convex structure and an anti-slip rubber pad is provided on the inner side of its vertical surface. When sliding inward, it can fit tightly against the outer wall of the mounting groove 15 to form a locking force. The two limiting blocks 21 are slidably connected internally by sliding... The rod 23 and the sliding rod 23 pass through the horizontal through holes of the two limiting blocks 21, serving as a guide shaft to constrain the movement trajectory of the limiting blocks 21 and ensure that they slide in a straight line in the horizontal direction. Two springs 22 are sleeved on the outside of the sliding rod 23. The two springs 22 are located between the shoulders of the two limiting blocks 21 and the sliding rod 23, respectively. When the limiting blocks 21 slide inward, they are compressed and accumulate elastic potential energy. After the mounting slot 15 is in place, the elastic force is released to push the limiting blocks 21 outward and lock them in place. The bottom of the support block 18 is fixedly connected to a height adjustment component, which includes a telescopic rod 26 and a screw 28. The vertical height of the device can be adjusted by sliding the telescopic rod 26, and the current height can be locked by tightening the screw 28 to meet the height requirements of different sampling scenarios.

[0027] Reference Figure 4 A fixed shaft 2 is fixedly connected to the top of the control panel 1. The fixed shaft 2 is used to stably support the structure above and ensure the overall vertical stability of the equipment. A support shaft 3 is fixedly connected to the top of the fixed shaft 2. The support shaft 3 can assist the fixed shaft 2 in sharing the load and also provides an installation base for the air trap 4. The air trap 4 is fixedly connected to the top of the support shaft 3. The air trap 4 is the core inlet for ambient air sampling. After activation, it can actively absorb outside air and provide an air source for subsequent sampling processes. A support plate 5 is fixedly connected to one side of the control panel 1. The support plate 5 provides a stable support platform for the absorption bottle 6 through a horizontally extended structural design, ensuring its stability during sampling. Two absorption bottles 6 are fixedly connected to the top of the support plate 5. The two absorption bottles 6 contain different absorption liquids, which are used to specifically absorb different components in the air to achieve the effect of classified sampling.

[0028] Both absorption bottles 6 are fixedly connected to the top of a flexible hose 7. The hose 7 is made of flexible material and can flexibly connect the absorption bottle 6 to the mounting hole 8 while ensuring airflow sealing. The ends of the two hoses 7 away from the absorption bottle 6 are fixedly connected to the mounting holes 8. The mounting holes 8 are fixed to the top of the control panel 1 and serve to position the hoses 7 so that air can enter the absorption bottle 6 according to a preset path. A display screen 10 is fixedly connected to one side of the control panel 1. The display screen 10 is activated after connecting to the data interface 13 and is used to display information such as device status and sampling time for convenient real-time monitoring by the user. Four control keys 11 are fixedly connected to one side of the control panel 1. The control keys 11 can be used to control the rotation of the rotating shaft 25, which in turn drives the support block 18 to rotate, thereby adjusting the sampling angle of the device to adapt to the sampling needs of different environments.

[0029] Reference Figures 2 to 4 The control panel 1 has three protective railings 9 fixedly connected to its exterior, which can provide physical protection for the control panel 1, preventing damage from external impacts and scratches, and extending the service life of the control panel 1. A timer button 12 is fixedly connected to one side of the control panel 1. By operating the timer button 12, the sampling time can be set, so that the device can carry out air sampling work for a preset duration, ensuring the accuracy and controllability of the sampling time. A data interface 13 is fixedly connected to one side of the control panel 1. The data interface 13 is used to connect to external devices to realize data transmission between the device and external devices, which facilitates the export of sampling data or the receipt of external commands. A temperature adjustment knob 14 is fixedly connected to one side of the control panel 1. The temperature adjustment knob 14 can adjust the temperature of temperature-related components inside the device or the sampling environment, ensuring that the device operates under suitable temperature conditions and ensuring the accuracy of the sampling data.

[0030] The height adjustment assembly includes a rotating shaft 25, which is rotatable and provides support and connection points for the rotation of the height adjustment assembly. A telescopic rod 26 is rotatably connected to the bottom of the rotating shaft 25. The telescopic rod 26 can change its length by sliding, thereby adjusting the height of the equipment to adapt to different sampling height requirements. A screw 28 is threadedly connected to the bottom of the telescopic rod 26, which engages with a screw hole on the telescopic rod 26. After adjusting the height of the telescopic rod 26, tightening the screw 28 can fix the position of the telescopic rod 26 and prevent it from slipping during use. A limiting roller 29 is fixedly connected to the bottom of the telescopic rod 26, which limits the rotation range of the support column 30 to ensure the stability of the support structure. A fixed roller 32 is fixedly connected to the bottom of the limiting roller 29, providing fixed support for the bottom of the entire height adjustment assembly and enhancing the overall stability of the equipment. Three support columns 30 are rotatably connected to the bottom of the limiting roller 29, and these three support columns 30 can rotate at the bottom of the limiting roller 29, cooperating with the connecting plate 31, etc., to form a support structure that supports the main body of the equipment.

[0031] Each of the three support columns 30 is rotatably connected to a connecting plate 31. The connecting plate 31 is used to connect the support column 30 and the sliding ring 27. When the sliding ring 27 slides, it drives the support column 30 to rotate, realizing the expansion and contraction of the support structure. The bottom of the telescopic rod 26 is slidably connected to the inside of the fixed roller 32, so that the telescopic rod 26 can remain stable when sliding inside the fixed roller 32. At the same time, the fixed roller 32 provides support and guidance for the bottom of the telescopic rod 26. A sliding ring 27 is rotatably connected to one side of the connecting plate 31. The sliding ring 27 can slide outside the fixed roller 32. By sliding, it drives the connecting plate 31 to rotate, which in turn drives the support column 30 to rotate, realizing the adjustment of the support structure.

[0032] The sliding ring 27 is internally slidably connected to the outside of the fixed roller 32. The fixed roller 32 provides a track for the sliding ring 27, allowing it to slide smoothly along the outside of the fixed roller 32. A motor 24 is fixedly connected to the top of the support block 18. After the motor 24 is started, it can drive the related components to rotate, realizing the adjustment of the equipment angle or other functions. It is the power source for the equipment to perform certain actions. The telescopic rod 26 has multiple screw holes inside. These screw holes cooperate with the screw 28. When the telescopic rod 26 is adjusted to different heights, it can be fixed by the screw 28 to meet the adjustment requirements of different heights. The internal sliding ring 27 is slidably connected to the outside of the fixed roller 32, ensuring the smoothness and stability of the sliding ring 27 sliding outside the fixed roller 32, thereby ensuring the reliability of the support structure adjustment.

[0033] Working principle: When it is necessary to sample ambient air, slide the telescopic rod 26 and adjust the screw 28 to the required height, then start the motor 24. The motor 24 drives the two sliding plates 20 to slide inward on the sleeper rail 19. When the two sliding plates 20 slide inward, they drive the two limiting blocks 21 to slide inward. When the two limiting blocks 21 slide inward, they drive the spring 22 to press inward. At this time, the mounting groove 15 is aligned with the fixing slot 16. Then, the two limiting blocks 21 slide outward under the elastic force of the two springs 22, so that the two limiting blocks 21 lock the mounting groove 15, thereby completing the installation of the equipment.

[0034] After connecting to the data interface 13, the display screen 10 is activated, and the device enters the preparation state. The rotating shaft 25 can be controlled to rotate via the control key 11. When the rotating shaft 25 rotates, it drives the support block 18 to rotate. The rotation of the support block 18 drives the object on the support block 18 to rotate, thereby adjusting the device to the required angle. The sampling time can be set by adjusting the timing button 12. When the start button is clicked, the air trap 4 begins to absorb air. The absorbed air enters different absorption bottles 6 through the absorbent liquid in the hose 7, thereby completing the ambient air sampling.

[0035] 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.
