Description

Technical Field

[0001] The present invention relates to the technical field of indoor air quality monitoring, and in particular to a fast, non-destructive, accurate and visual indoor pollutant detection device. Background Art

[0002] In the development of modern society, indoor air pollution has become an important issue of general concern. Studies have shown that harmful pollutants in indoor air, such as formaldehyde, benzene and its derivatives, have serious harm to human health. These substances usually come from building materials, furniture, decorative materials, paints, coatings and adhesives. Long-term exposure to these pollutants may lead to serious health problems such as respiratory diseases, allergic reactions, and even cancer.

[0003] At present, the commonly used indoor air quality detection methods include chemical analysis and physical detection methods. Chemical analysis methods usually require complex operation steps and long detection time, and require destructive sampling, which leads to certain limitations in practical applications. While physical detection methods, such as electrochemical sensors, are relatively simple to operate, they are insufficient in sensitivity and accuracy, and it is difficult to meet the needs of high-precision detection. In addition, most existing detection equipment lacks real-time monitoring capabilities and intuitive visualization functions, making it difficult for users to quickly obtain specific information on indoor air quality, and thus difficult to evaluate the effect of indoor pollution control. Summary of the invention

[0004] The present invention discloses a rapid, non-destructive, precise and visual indoor pollutant detection device, which aims to improve the sensitivity and accuracy of detection, and also has the advantages of real-time monitoring and non-destructive detection, so that users can quickly and accurately understand the indoor air quality status.

[0005] A fast, non-destructive, accurate and visual indoor pollutant detection device includes the following main parts: a pollutant absorption container, which is provided with a fluorescent probe dripping inlet, and the fluorescent probe reagents corresponding to formaldehyde and benzene are dripped into the multiple inlets respectively, and these pollutants are marked by fluorescent probe technology; a pollutant absorption conduit is provided, which is used to absorb indoor air into the container; a fluorescent particle classification conduit is provided, which classifies the particles according to their size and makes them pass through the laser beam in sequence. This process is usually achieved through holes or channels with different apertures. A heating tube is provided, which is located inside the pollutant absorption container and is used to accelerate the reaction process of the pollutant. An insulating net is provided on the upper part of the heating tube to prevent the detection gas from directly contacting the heating tube, thereby ensuring the reaction efficiency and safety. The laser particle counter is connected to the end of the fluorescent particle classification conduit to provide a stable laser beam to irradiate the particles in the air. The laser particle counter is equipped with an optical sensor to detect the scattering or blocking of laser by particles; a signal processor is provided to receive the signal from the optical sensor and convert it into a measurable electrical signal; a data converter is provided to further convert the electrical signal into a digital signal for further analysis and display; a display screen is provided to display the particle counting results in real time, including the count of particles of different sizes and the total particle count; and a control button is provided to control the laser particle counter. The MR head display has a high-definition three-dimensional visualization function and can receive and display the distribution and concentration data of the measured pollutants in real time. Its interactive design allows users to interact with the environment through head movements, gestures or voice.

[0006] The headset supports wireless data transmission, has good wearing comfort and long-term power management, ensuring a stable, safe and intuitive detection experience in various indoor environments. The particle suspension technology uses aerosol and tracer particles to suspend the marked pollutant particles in the air. By controlling the flow rate and direction of the airflow, the fluorescently marked pollutant particles are evenly distributed in the room. The fluorescent particles enter the laser particle counter through the classification duct. The laser beam illuminates the particles to stimulate the fluorescent signal. The detector captures the fluorescent signal and transmits it to the computer for processing, generating real-time data on the concentration and distribution of pollutants, and transmitting it to the MR headset via wireless or wired methods. After wearing the MR headset, the user can see the concentration, distribution and change trend of indoor air pollutants updated in real time.

[0007] Compared with the prior art, the beneficial effects of the present invention are: a fast, non-destructive, accurate and visual indoor pollutant detection device combines fluorescent labeling technology, laser particle counting technology and MR head display visualization technology, has the advantages of high sensitivity and high precision, and can monitor the concentration and distribution of pollutants in indoor air in real time and non-destructively, and display them through intuitive three-dimensional graphics. It is easy to operate and users can quickly obtain air quality information. It is widely applicable to various indoor environments such as residences, offices and schools, greatly improving the efficiency and accuracy of air quality detection.

[0008] The present invention combines advanced fluorescent labeling technology, laser particle counting technology and MR head display visualization technology to provide an efficient and reliable indoor air quality detection and evaluation solution, aiming to improve people's living environment and ensure their health and safety.

[0014] Examples, such as Figure 1-2As shown, a rapid, non-destructive, accurate and visual indoor pollutant detection device described in this embodiment includes: a pollutant absorption container 1, which is provided with a transparent glass shell 9, and a fluorescent probe dropping inlet 5 is provided on the top, including a fluorescent probe dropping inlet 15 corresponding to benzene substances, a fluorescent probe dropping inlet 16 corresponding to aldehyde substances, and a fluorescent probe dropping inlet 17 corresponding to other pollutants, into which fluorescent probe reagents corresponding to formaldehyde, benzene and other pollutants to be tested are dropped respectively; a pollutant absorption duct 7 is provided on the top to collect indoor air; a fluorescent particle classification duct 6 is provided on the side, including a fluorescent particle duct 18 corresponding to benzene substances, a fluorescent particle duct 19 corresponding to aldehyde substances, and a fluorescent particle duct 20 corresponding to other pollutants, which can classify the particles according to their size and make them pass through the laser beam in sequence, which is usually achieved by using holes or channels with different apertures. A laser particle counter 2, wherein the laser particle counter 2 is connected to the end of the fluorescent particle classification conduit 6, and provides a stable laser beam for irradiating particles in the air; a laser particle counter operation button 14 is provided; a laser particle counter display screen 13 is provided for real-time display of particle counting results, which usually includes counts of particles of different sizes and total particle counts. In addition, the laser particle counter is provided with a signal processor for receiving signals from optical sensors and converting them into measurable electrical signals; a data converter is provided for converting electrical signals into digital signals for further analysis and display; an optical sensor is provided, which is usually located on the path of the laser beam, and is used to detect scattering or blocking of light by particles passing through the laser beam; and a filter is provided to prevent the air exhausted by the instrument from affecting the clean area.

[0015] In order to speed up the process, a heating tube 11 is arranged inside the pollutant absorption container 1 , and a heat insulation net 10 is arranged on the upper part of the heating tube 11 to prevent the detection gas in the pollutant absorption container 1 from directly contacting the heating tube 11 .

[0016] In order to visualize the parameters on the laser particle counter 2, a fast, non-destructive, accurate and visual indoor pollutant detection device is equipped with an MR headset 4. The MR headset 4 is specifically a Mediated Reality head-mounted display device with high-definition three-dimensional visualization function, which can receive and display the distribution and concentration data of the measured pollutants in real time; its interactive design enables users to interact with the virtual environment through head movements, gestures or voice, and spatial mapping technology ensures the precise alignment of fluorescent labeled particles with the environment; at the same time, the MR headset 4 supports wireless data transmission, and takes into account wearing comfort and power management for long-term use, ensuring that stable, safe and intuitive indoor air quality detection can be provided under various indoor environmental conditions.

[0017] Using aerosols and tracer particles, the marked pollutant particles are suspended in the air. The flow rate and direction of the airflow are controlled so that the fluorescently marked pollutant particles are evenly distributed in the room. The fluorescent particles enter the laser particle counter 2 through the classification duct 6. The high-frequency laser beam is irradiated on the particles to stimulate their fluorescent signals. After the detector captures the fluorescent signals, the data is transmitted to the computer 3. After processing by the computer 3, real-time data on the concentration and distribution of pollutants are generated and transmitted to the MR headset 4 by wireless or wired means. After wearing the MR headset 4, the user can see the concentration, distribution and change trend of indoor air pollutants updated in real time. These data are presented in the form of intuitive three-dimensional graphics or charts, allowing users to quickly understand the indoor air quality status.
