Description

Technical Field

[0001] This utility model relates to the field of air detection technology, and in particular to a portable rapid air pollutant detection device. Background Technology

[0002] Rapid air pollutant detection devices are a type of equipment that can collect air samples in real time and quickly analyze and output data on the concentration of harmful pollutants in the air through specific detection principles. They cover daily air quality monitoring in homes, offices, schools, and hospitals, and are also suitable for on-site investigations in high-incidence outdoor pollution areas such as factory workshops, construction sites, and roadsides, providing real-time data support for environmental monitoring personnel.

[0003] Traditional rapid air pollutant detection devices consist of a core detection module, a data display module, a power supply module, a sampling module, and a housing structure. In actual use, users need to place the device on a flat surface and start it by connecting an external power source or using a built-in battery. After the sampling module draws in an air sample, the core detection module analyzes the pollutants, and the data display module outputs the detection results. However, the core detection module of these traditional devices has a single function and can only detect one or two types of pollutants. If multiple pollutants need to be monitored, multiple detection devices with different functions need to be carried, which not only increases the equipment investment cost but also makes the detection operation more complicated.

[0004] To address the issue of limited functionality in traditional devices, existing technologies integrate multiple types of sensors into the core detection module to simultaneously detect various pollutants. They also add data storage chips and USB interfaces to store and export detection data. However, in practical use, integrating multiple types of sensors increases the size, weight, and overall volume. Furthermore, the core detection module uses a multi-sensor integrated design rather than modular disassembly, resulting in rigid connections between modules and making it too bulky and inconvenient to carry, failing to meet users' needs for efficient and convenient outdoor monitoring.

[0036] 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.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a portable rapid air pollutant detection device, including an operating table 1, which serves as the core of the device's control operation, for integrating control components and providing operation for the user. A locking mechanism 2 is provided on the right side of the operating table 1 to enable quick assembly and disassembly and stable connection between the operating table 1 and the detection table 4. The detection table 4 is provided on the right side of the locking mechanism 2, serving as the core area for gas detection, for accommodating detection elements and completing the gas detection process. A filter mechanism 3 is provided on the front side of the detection table 4 to pre-treat the gas entering the detection table 4, removing impurities from the gas to ensure detection accuracy.

[0038] The engaging mechanism 2 includes two locking blocks 201 that cooperate with the locking slots 202 to achieve mechanical connection. Both locking blocks 201 are fixedly connected to the top right side of the operating table 1. Two locking slots 202 are provided on the top left side of the testing table 4 to accommodate the locking blocks 201 and provide connection space. Two ball grooves 203 are provided on the front and rear sides of the inner walls of the two locking slots 202 to accommodate springs 204 and sliders 205. Springs 204 are fixedly connected to the inner walls of the multiple ball grooves 203 to provide elastic force, pushing the sliders 205 to engage with the locking blocks 201. Each side of the spring 204 is fixedly connected to a slider 205, which engages with the locking block 201 under the action of the spring 204 to enhance the connection stability. Multiple sliders 205 engage with their corresponding locking blocks 201. A plug 206 is fixedly connected to the bottom right side of the operating table 1 and cooperates with the slot 207 to realize the data and power transmission between the operating table 1 and the detection table 4. A slot 207 is fixedly connected to the bottom left side of the detection table 4 to accommodate the plug 206 and complete the circuit connection with the operating table 1. The plug 206 engages with the slot 207.

[0039] Specifically, during use, first take out the independently stored operating table 1 and testing table 4. During assembly, align the two locking blocks 201 on the top right side of the operating table 1 with the corresponding two locking slots 202 on the top left side of the testing table 4, and push them in horizontally. During the pushing process, the locking blocks 201 press against the ball grooves 203 inside the inner wall of the slots 202. The ball grooves 205 compress the springs 204 and retract into the slots 203, preventing the locking blocks 201 from being obstructed. When the locking blocks 201 are fully inserted into the slots 202, the surface of the locking blocks 201 fits against the corresponding position of the ball grooves 203. The springs 204 elastically return to their original position, pushing the ball grooves 205 out of the ball grooves 203 and tightly engaging with the locking blocks 201, thus achieving mechanical locking of the operating table 1 and testing table 4 and preventing separation due to vibration during use. At the same time, the plug 206 on the bottom right side of the operating table 1 is simultaneously inserted. Insert the device into slot 207 at the bottom left of the testing platform 4 to complete the data and power connection without additional wiring. After assembly, operate the display screen 5 of the control panel 1 to start the built-in air pump of the testing platform 4. The air pump drives the external air through the filter mechanism 3 before entering the testing platform 4 to complete the test. When the test is finished or maintenance is required, hold the top handles of the control panel 1 and the testing platform 4 with both hands and pull in the opposite direction. The pulling force causes the locking block 201 to squeeze the sliding ball 205, the spring 204 to compress again, the sliding ball 205 to return to the ball groove 203, the locking block 201 to disengage from the slot 202, and the plug 206 to separate from the slot 207 simultaneously, achieving quick disassembly. The control panel 1 and the testing platform 4 can be stored and transported separately, reducing the footprint, lowering the overall weight, and improving portability. In case of a single module failure, it can be replaced individually, solving the problem of insufficient modularity in existing devices.

[0040] Reference Figure 1 , Figure 4 and Figure 5Two fixed bases 301 are fixedly connected to the top front side of the testing platform 4, which fix and support the filter tank 302 and the adsorption tank 303. The filter tank 302 is fixedly connected to the front side of the top fixed base 301 and is filled with filter material to remove solid impurities in the gas. The adsorption tank 303 is fixedly connected to the front side of the bottom fixed base 301 and is filled with adsorbent to remove volatile organic impurities in the gas. The right end of the filter tank 302 and the adsorption tank 303 is provided with the same diversion pipe 304, which distributes the outside gas to the filter tank 302 and the adsorption tank 303. The left side of the diversion pipe 304 is connected to two valves 305, which control the opening and closing of the passage between the diversion pipe 304 and the filter tank 302 and the adsorption tank 303, respectively. The right end of both the filter tank 302 and the adsorption tank 303 is provided with a detection pipe 306, which transports the pretreated gas to the testing platform 4. Both detection pipes 306 are... The filter tank 302 and the adsorption tank 303 are connected to the upper left front end of the detection platform 4. The left and right sides of the filter tank 302 and the adsorption tank 303 are equipped with quick-release components 307 to realize quick disassembly and assembly of the filter tank 302, the adsorption tank 303 and other components, which facilitates maintenance and replacement of consumables. The quick-release component 307 includes multiple connecting cylinders 3071, which connect the filter tank 302, the adsorption tank 303 and the diversion pipe 304 and the detection pipe 306. The multiple connecting cylinders 3071 are rotatably connected to the left and right ends of the filter tank 302 and the adsorption tank 303 respectively. The inner wall of the multiple connecting cylinders 3071 is provided with threaded grooves 3072, which cooperate with the threaded cylinders 3073 to realize threaded connection and fixation. The diversion pipe 304 and the two detection pipes 306 are fixedly connected to the adjacent side of the threaded cylinders 3073, which cooperate with the threaded grooves 3072 to complete the fixation of the connecting cylinders 3071. The multiple threaded cylinders 3073 are threadedly connected to the corresponding threaded grooves 3072 respectively.

[0041] Specifically, before testing, the connection status of the filter mechanism 3 needs to be confirmed. Two fixed bases 301 on the top front side of the testing platform 4 fix the filter tank 302 and the adsorption tank 303 respectively. Their right ends are connected by a diversion pipe 304. Two valves 305 on the left side of the diversion pipe 304 control the gas passages of the two tanks respectively. The right ends of both the filter tank 302 and the adsorption tank 303 are connected to the upper left front side of the testing platform 4 via a detection pipe 306, ensuring that gas can enter the testing platform 4. When testing gas containing dust and impurities, close the valve 305 corresponding to the bottom adsorption tank 303 and open the valve 305 corresponding to the top filter tank 302. External gas enters the filter tank 302 through the diversion pipe 304. After the filter material inside the tank intercepts the dust, clean gas passes through the detection pipe. The tube 306 enters the detection station 4. If the gas contains organic matter, the valve 305 in the filter tank 302 is closed and the valve 305 in the adsorption tank 303 is opened. The gas enters the adsorption tank 303, and the adsorbent in the tank adsorbs the organic matter. Then, the gas enters the detection station 4 through the detection tube 306. When it is necessary to replace the consumables in the filter tank 302 and the adsorption tank 303, rotate the connecting cylinder 3071 at both ends of the filter tank 302 and the adsorption tank 303 to separate the threaded groove 3072 on its inner wall from the threaded cylinder 3073 on the diversion tube 304 and the detection tube 306. The tank can then be removed to replace the consumables. After replacement, align the connecting cylinder 3071 with the threaded cylinder 3073 and rotate it in the opposite direction to complete the thread lock. This enables quick disassembly and assembly, ensuring the continuous and efficient operation of the filter mechanism 3.

[0042] Reference Figure 1 , Figure 3 and Figure 6 The front upper middle part of the operating console 1 is fixedly connected to a display screen 5, which displays the working status of the device, detection parameters and detection results. Multiple control buttons 6 are fixedly connected to the left and right sides of the front upper part of the operating console 1, which allow users to input operation commands and realize the detection mode switching and parameter adjustment functions. The lower left side of the front of the operating console 1 is provided with a power interface 7, which is connected to an external power source to power the device and charge the battery. The lower middle side of the front of the operating console 1 is provided with a USB interface 8, which exports detection data and realizes communication between the device and external devices. The lower right side of the front of the operating console 1 is fixedly connected to a switch 9, which controls the power supply of the device. The bottom left side of the operating console 1 is provided with a slide groove 10, which provides a sliding track for the battery box 11, making it easy to pull out and push in the battery box 11. The inner wall of the slide groove 10 is slidably connected to the battery box 11 to hold the battery and provide portable power supply for the device.

[0043] Specifically, before use, pull out the battery box 11 along the slide 10, insert the compatible battery, and push the slide 10 back to complete the power supply; alternatively, an external power source can be connected through the power interface 7. Press the switch 9 to start the device, and the display screen 5 in the middle of the front will light up, showing the device status and detection parameters. During detection, the detection mode and parameters can be set and adjusted through the control buttons 6 on the left and right sides of the front. Operation commands are fed back to the display screen 5 in real time, and detection data can be exported through the USB interface 8. When the battery power is low, the display screen 5 will prompt that the battery box 11 can be pulled out to replace the battery and connect to the power interface 7 for power supply. This does not require interruption of the core components of the device, ensuring the continuity of detection and making it suitable for outdoor scenarios without a fixed power source.

[0044] Reference Figure 2 , Figure 6 and Figure 7 A dust cover 12 is fixedly connected to the top of the testing platform 4, covering the top of the testing platform 4 to prevent dust from entering the interior of the testing platform 4 and protecting the testing components. A fixing seat 13 is fixedly connected to the right side of the dust cover 12, which cooperates with the diversion pipe 304 to enhance the connection stability between the dust cover 12 and the diversion pipe 304. The fixing seat 13 engages with the upper side of the diversion pipe 304. An air inlet pipe 14 is fixedly connected to the top of the diversion pipe 304 to guide external gas into the diversion pipe 304. An air outlet 15 is opened at the bottom front end of the testing platform 4 to allow air to pass through after testing. The gas is discharged from the testing platform 4. Multiple heat dissipation slots 16 are provided on the rear side of both the operating platform 1 and the testing platform 4 to dissipate the heat generated by the internal components of the operating platform 1 and the testing platform 4 during operation, and to prevent the equipment from overheating and affecting its performance. Two brackets 17 are fixedly connected to the bottom of both the operating platform 1 and the testing platform 4 to support the operating platform 1 and the testing platform 4, so that the bottom of the device is kept at a distance from the contact surface, which facilitates heat dissipation and stable placement. Multiple friction grooves 18 are provided on the bottom of the multiple brackets 17 to increase the friction between the brackets 17 and the contact surface and prevent the device from sliding during use.

[0045] Specifically, before use, the dust cover 12 is engaged with the test platform 4, and the right-side fixing seat 13 is separated from the upper side of the diversion pipe 304, exposing the air inlet pipe 14. During testing, external gas enters the diversion pipe 304 through the air inlet pipe 14, and after pretreatment, it enters the test platform 4. The gas after testing is discharged from the bottom air outlet 15 at the front end. During the testing process, the heat dissipation grooves 16 on the rear side of the operating table 1 and the test platform 4 can dissipate the heat generated by the internal components in a timely manner to avoid overheating and affecting performance. When placed, the bottom bracket 17 supports the device, and the friction groove 18 at the bottom of the bracket 17 increases the friction with the contact surface to prevent slippage. After the test is completed, the dust cover 12 is covered, and the fixing seat 13 engages with the diversion pipe 304 to prevent dust from entering the air inlet pipe 14 and the interior of the test platform 4.

[0046] Working principle: The independently stored operating table 1 and testing table 4 are taken out separately. One side of the operating table 1 integrates two symmetrically distributed locking blocks 201, each with a pre-drilled circular groove adapted to the sliding ball 205 mechanism. The mating surface of the testing table 4 has two slots 202 matching the size of the locking blocks 201. During assembly, the two locking blocks 201 are aligned with their corresponding slots 202 and inserted horizontally. The arc-shaped end face of the locking block 201 presses against the sliding ball 205, causing the sliding ball 205 to overcome the elastic force of the spring 204 and retract into the limiting sleeve, ensuring smooth insertion of the locking block 201. When the locking block 201 is fully inserted into the slot 202, the circular groove inside the locking block 201 coincides with the position of the sliding ball 205. The spring 204 springs back, pushing the sliding ball 205 into the groove, forming a mechanical lock. Simultaneously, the plug 206 at the end of the locking block 201... The slot 207 at the bottom of the card slot 202 engages tightly, completing the data and power connection between the operating table 1 and the testing table 4. When the testing task is completed or a component needs to be repaired separately, hold the handles on the top of the operating table 1 and the testing table 4 with both hands and pull gently in opposite directions. The pulling force will cause the card block 201 to squeeze the slider 205, causing the slider 205 to compress the spring 204 again and disengage from the groove. At this time, the card block 201 can be pulled out of the card slot 202, and the plug 206 and the slot 207 separate simultaneously, completing the quick disassembly of the two. This modular structure design allows the operating table 1 and the testing table 4 to be stored and transported separately, reducing the overall footprint and improving portability. At the same time, if a module malfunctions, there is no need to disassemble and repair the entire device; only the faulty module needs to be replaced, reducing maintenance costs and time costs. This solves the problems of low modularity and poor portability in existing technologies.

[0047] Furthermore, impurities in the air will directly adhere to the surface of the sensor built into the detection station 4, which will not only cause the sensor detection accuracy to drift, but also accelerate the aging of the sensor and shorten its service life. In the actual detection process, if the target of detection is gas that needs to be dust removed, the valve 305 corresponding to the filter tank 302 on the upper side is opened. At this time, the outside gas enters through the air inlet pipe 14. Under the negative pressure of the air pump built into the detection station 4, it will enter the filter tank 302 along the diversion pipe 304 to filter the gas. The filtered clean gas then enters the sensor detection chamber of the detection station 4 through the detection pipe 306. If the target of detection is gas that needs to be organic matter removed, the valve 305 corresponding to the adsorption tank 303 is opened. After the gas enters the adsorption tank 303 through the diversion pipe 304, the volatile organic matter in it will be captured by the adsorbent. The gas after removing the organic matter then enters the detection station 4 through the detection pipe 306 for detection. This switchable graded pretreatment design can accurately match the filtration scheme according to the actual detection needs, ensuring the accuracy of the detection results from the source, and solving the problem that the existing technology cannot adapt to different impurity removal needs.

[0048] 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.
