Description

Technical Field

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

[0002] Airborne particulate matter refers to tiny particles suspended in the air, including dust, pollen, spores, sea salt particles, volcanic ash, etc. It is also known as particulate matter or aerosol particles. By detecting and analyzing airborne particulate matter, its sources can be traced, such as industrial emissions, vehicle exhaust, dust, and biomass combustion, thus identifying the main sources of pollution.

[0003] In existing air particulate detection devices, impurities from airborne particles tend to accumulate on the sensor over prolonged use. This prevents the sensor from making sufficient contact with the target substance in the air, hindering its ability to accurately detect the true concentration of the substance and leading to inaccurate measurement results. To address this issue, we provide a portable air particulate detection device. Utility Model Content

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model is a portable airborne particulate detection device, including an instrument body 1. Specifically, the instrument body 1 consists of a data acquisition module, a signal processing module, a data processing module, and a power supply module. The data acquisition module includes a protective shell 2 fixed on the instrument body 1. One end of the protective shell 2 penetrates the instrument body 1 and extends into the interior. A groove 3 is provided on the outer wall of the protective shell 2. A sensor 4 is fixedly connected inside the groove 3. The sensor 4 is electrically connected to the signal processing module, the data processing module, and the power supply module. A cleaning component that works with the sensor 4 is fixedly installed inside the instrument body 1.

[0024] The acquisition module on the instrument body 1 collects airborne particles. After being processed by the signal processing module and the data processing module, the airborne particle data is displayed on the screen on the instrument body 1. The power module supplies power to the above modules. In conjunction with the reciprocating motion of the cleaning component, the sensor 4 in the acquisition module is adsorbed and cleaned to avoid the accumulation of airborne particulate impurities on the surface of the sensor 4 after long-term use, which would cause the sensor 4 to collect inaccurate data.

[0025] Furthermore, the cleaning component includes a miniature pump body 7, the suction end of the miniature pump body 7 is connected to a connecting pipe 6, one end of the connecting pipe 6 is connected to a vacuum head 10 that slides inside the protective shell 2, the bottom of the vacuum head 10 is fixedly provided with a power source, and the outer wall of the miniature pump body 7 is fixedly provided with a collection component that works in conjunction with the cleaning component.

[0026] When the micro pump body 7 is connected to an external power source, it starts to generate negative pressure inside the suction head 10 through the air intake port of the micro pump body 7 and the connecting pipe 6. The connecting pipe 6 is made of soft material. The negative pressure inside the suction head 10 is used to adsorb and clean the air particles and impurities on the surface of the sensor 4. The adsorbed and cleaned impurities are transported to the collection component for unified processing.

[0027] Furthermore, the power source is specifically an electric push rod 5. The bottom of the electric push rod 5 is fixed to the top of the micro pump body 7. The inside of the protective shell 2 is provided with a sliding groove 9 that is used in conjunction with the electric push rod 5 and the vacuum head 10. The sliding groove 9 is connected to the groove 3.

[0028] An external power source powers the electric push rod 5, which in turn drives the suction head 10 to extend and retract. The extension and retraction of the suction head 10 within the slide groove 9 allows for more comprehensive adsorption and cleaning of particulate impurities on the surface of the sensor 4, preventing incomplete adsorption on the surface of the sensor 4.

[0029] Furthermore, the collection assembly includes a housing 8, and the outlet end of the micro pump body 7 is connected to a connecting pipe 2 15. The end of the connecting pipe 2 15 is connected to the housing 8. A collection box 11 is slidably connected inside the housing 8, and one end of the collection box 11 passes through the instrument body 1.

[0030] The particulate impurities adsorbed by the micro pump body 7 are discharged from the outlet end of the micro pump body 7 through the connecting pipe 15 to the collection box 11 inside the housing 8. The housing 8 and the collection box 11 allow the gas in the micro pump body 7 to pass through. When a certain amount of impurities are collected in the collection box 11, the collection box 11 is pulled out and the impurities in the collection box 11 are poured out, thus avoiding the discharge of impurities adsorbed by the micro pump body 7 to the outside environment and causing pollution.

[0031] Furthermore, a rotating shaft 13 is fixedly connected to the outer wall of the instrument body 1, and a limiting plate 12 that is used in conjunction with the collection box 11 is rotatably connected to the outer wall of the rotating shaft 13.

[0032] Push the collection box 11 into the housing 8 and rotate the limiting plate 12 to block the collection box 11, so as to prevent the collection box 11 from shaking and falling out of the housing 8 during use, causing the impurities in the collection box 11 to spill out.

[0033] Furthermore, a handle 14 is fixedly connected to the top of the instrument body 1.

[0034] The handle 14 on the instrument body 1 makes it easy for users to carry.

[0035] The operation process of this embodiment is as follows: The acquisition module on the instrument body 1 collects airborne particles. After processing by the signal processing module and the data processing module, the airborne particle data is displayed on the display screen on the instrument body 1. The power supply module supplies power to the above modules. The micro pump 7 is connected to an external power source and started. The air intake of the micro pump 7 generates negative pressure inside the suction head 10 through the connecting pipe 6. The connecting pipe 6 is made of soft material. The negative pressure inside the suction head 10 is used to adsorb and clean airborne particles and impurities on the surface of the sensor 4. The external power source supplies power to the electric push rod 5, which drives the suction head 10 to extend and retract. Through the extension and retraction of the suction head 10 in the slide groove 9 and the groove 3, the surface of the sensor 4 can be more comprehensively cleaned. The micropump 7 adsorbs and cleans particulate impurities on the surface of the sensor 4 to avoid incomplete adsorption. The particulate impurities adsorbed by the micropump 7 are discharged from the outlet end of the micropump 7 into the collection box 11 inside the housing 8 through the connecting pipe 15. The housing 8 and the collection box 11 allow the gas in the micropump 7 to pass through. When a certain amount of impurities are collected in the collection box 11, pull the collection box 11 out and pour out the impurities in the collection box 11 to avoid the impurities adsorbed by the micropump 7 being discharged outdoors and causing environmental pollution. Push the collection box 11 into the housing 8 and rotate the limiting plate 12 to block the collection box 11 to prevent the collection box 11 from shaking and falling off the housing 8 during use, which would cause the impurities in the collection box 11 to spill.
